Many studies have examined effects of predators on guppy behaviour, reproduction, survival strategies, feeding and other life-history traits, but few have studied variation in their parasite diversity. We surveyed parasites of 18 Trinidadian populations of guppy, to provide insight on the geographical mosaic of parasite variability, which may act as a source of natural selection acting on guppies. We found 21 parasite species, including five new records for Trinidad. Spatial variation in parasite diversity was significantly higher than that of piscine predators, and significant variation in parasite richness among individuals and populations was correlated with (i) host size, (ii) snail species richness, and (iii) the distance between populations. Differences in parasite species richness are likely to play an important, yet underestimated role in the biology of this model species of vertebrate ecology and evolution. © 2020 The Authors.The evolution of spoken languages has been studied since the mid-nineteenth century using traditional historical comparative methods and, more recently, computational phylogenetic methods. By contrast, evolutionary processes resulting in the diversity of contemporary sign languages (SLs) have received much less attention, and scholars have been largely unsuccessful in grouping SLs into monophyletic language families using traditional methods. To date, no published studies have attempted to use language data to infer relationships among SLs on a large scale. Here, we report the results of a phylogenetic analysis of 40 contemporary and 36 historical SL manual alphabets coded for morphological similarity. Our results support grouping SLs in the sample into six main European lineages, with three larger groups of Austrian, British and French origin, as well as three smaller groups centring around Russian, Spanish and Swedish. The British and Swedish lineages support current knowledge of relationships among SLs based on extra-linguistic historical sources. With respect to other lineages, our results diverge from current hypotheses by indicating (i) independent evolution of Austrian, French and Spanish from Spanish sources; (ii) an internal Danish subgroup within the Austrian lineage; and (iii) evolution of Russian from Austrian sources. © 2020 The Authors.Agent-based models (ABMs) are gaining traction as one of the most powerful modelling tools within the social sciences. They are particularly suited to simulating complex systems. Despite many methodological advances within ABM, one of the major drawbacks is their inability to incorporate real-time data to make accurate short-term predictions. This paper presents an approach that allows ABMs to be dynamically optimized. Through a combination of parameter calibration and data assimilation (DA), the accuracy of model-based predictions using ABM in real time is increased. We use the exemplar of a bus route system to explore these methods. The bus route ABMs developed in this research are examples of ABMs that can be dynamically optimized by a combination of parameter calibration and DA. The proposed model and framework is a novel and transferable approach that can be used in any passenger information system, or in an intelligent transport systems to provide forecasts of bus locations and arrival times. https://www.selleckchem.com/products/heptadecanoic-acid.html © 2020 The Authors.Chromatin remodelling and transcription factors play important roles in lineage commitment and development through control of gene expression. Activation of selected lineage-specific genes and repression of alternative lineage-affiliated genes result in tightly regulated cell differentiation transcriptional programmes. However, the complex functional and physical interplay between transcription factors and chromatin-modifying enzymes remains elusive. Recent evidence has implicated histone demethylases in normal haematopoietic differentiation as well as in malignant haematopoiesis. Here, we report an interaction between H3K4 demethylase JARID1A and the haematopoietic-specific master transcription proteins SCL and GATA1 in red blood cells. Specifically, we observe a direct physical contact between GATA1 and the second PHD domain of JARID1A. This interaction has potential implications for normal and malignant haematopoiesis. © 2020 The Authors.We developed a time-dependent stochastic neutral model for predicting diverse temporal trajectories of biodiversity change in response to ecological disturbance (i.e. habitat destruction) and dispersal dynamic (i.e. emigration and immigration). The model is general and predicts how transition behaviours of extinction may accumulate according to a different combination of random drift, immigration rate, emigration rate and the degree of habitat destruction. We show that immigration, emigration, the areal size of the destroyed habitat and initial species abundance distribution (SAD) can impact the total biodiversity loss in an intact local area. Among these, the SAD plays the most deterministic role, as it directly determines the initial species richness in the local target area. By contrast, immigration was found to slow down total biodiversity loss and can drive the emergence of species credits (i.e. a gain of species) over time. However, the emigration process would increase the extinction risk of species and accelerate biodiversity loss. Finally but notably, we found that a shift in the emigration rate after a habitat destruction event may be a new mechanism to generate species credits. © 2020 The Authors.It is often observed that married women have a later age of natural menopause (ANM) than unmarried women; however, the reason for this association is unknown. We test an original hypothesis that sexual frequency acts as a bio-behavioural mediator between marital status and ANM. We hypothesize that there is a trade-off between continued ovulation and menopause based on the woman's chances of becoming pregnant. If a woman is sexually inactive, then pregnancy is impossible, and continued investment in ovulation would not be adaptive. In addition, we test an existing hypothesis that the observed relationship is because of the exposure to male pheromones. Data from 2936 women were drawn from 11 waves of the Study of Women's Health Across the Nation, which is a longitudinal study conducted in the United States. Using time-varying Cox regression, we found no evidence for the pheromone hypothesis. However, we did observe that women who reported to have sex weekly during the study period were 28% less likely to experience menopause than women who had sex less than monthly.

When analyzed in lithium-sulfur batteries, these sulfur-carbon composites show high specific capacities of 1100 mAh g-1 at a low C-rate of 0.1 C and above 500 mAh g-1 at a high rate of 2 C for sulfur contents in the range of 50-80 wt%. Remarkably, the composites with 51-65 wt% S can still provide above 400 mAh g-1 at an ultra-fast rate of 4 C (where a charge and discharge cycle takes only ten minutes). The good rate capability and sulfur utilization was additionally assessed for cathodes with a high sulfur content (65-74%) and a high sulfur loading (>5 mg cm-2). In addition, cathodes of 4 mg cm-2 successfully cycled for 260 cycles at 0.2 C showed only a low loss of 0.12%/cycle.There have been concerns about abuse and unnecessary chronic administration of zolpidem, and zolpidem's relation to suicide risk. https://www.selleckchem.com/products/eidd-1931.html To investigate the temporal association of zolpidem with the risk of suicide, we conducted a 12-year, population-based, retrospective cohort study on the National Health Insurance Service-National Sample Cohort (NHIS-NSC), South Korea. Data were collected from 2002 to 2013 from the NHIS-NSC, and data cleaning was performed for 1,125,691 subjects. Cox proportional hazards regression analysis was used to investigate the correlation over time between zolpidem medication and suicide. Over intervals commencing after 80 months of observation, the adjusted hazard ratio of suicides associated with the use of the zolpidem was 2.01 (95% CI 1.58-2.56; p  less then  0.001). The mean cumulative number of days of zolpidem prescription was significantly longer in the suicide group than in the non-suicide group after log-transformation (p = 0.005). Cases of chronic use of zolpidem (over six months or one year) were significantly more common in the suicide group compared to the non-suicide group (p = 0.002 and 0.005, respectively). Subjects who received zolpidem medication had a significantly higher risk of suicide after at least 80 months of observation, suggesting a long-term increased suicide risk associated with insomnia exposed to zolpidem medication.The use of illicit drugs causes unquestionable societal and economic damage. To implement actions aimed at combating drug abuse, it is necessary to assess illicit drug consumption patterns. The purpose of this paper was to develop, optimize, validate and apply a procedure for determining new psychoactive substances (NPSs) and classic drugs of abuse and their main metabolites in wastewater samples by using solid phase extraction (SPE) and high-performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS). Moreover, detailed validation of the procedure was conducted. The developed SPE-HPLC-MS/MS procedure (within the sewage-based epidemiology strategy) allowed for the simultaneous, selective, very sensitive, accurate (recoveries ≥ 80.1%) and precise (CV ≤ 8.1%) determination of new and classic psychoactive substances in wastewater samples. This study is characterized by new scientific elements, especially in terms of the freeze-thaw and post-preparative stability of the selected psychoactive substances. This is the first time that NPSs (mephedrone and ketamine), the main metabolites of heroin (6-acetylmorphine, 6-AM) and marijuana (11-nor-9-carboxy-Δ9-tetrahydrocannabinol, THC-COOH) have been detected and monitored in Poland. This study is also the first to corroborate the data available from the EMCDDA and EUROPOL report and indicates that the retail market for cocaine is expanding in Eastern Europe.Humpback whales (Megaptera novaeangliae) are known for their nearshore distribution during the breeding season, but their pelagic habitat use patterns remain mostly unexplored. From 2016 to 2018, 18 humpback whales were equipped with depth-recording satellite tags (SPLASH10) to shed light on environmental and social drivers of seamount association around New Caledonia in the western South Pacific. Movement paths were spatially structured around shallow seamounts (80 m, max 616 m) were also recorded (11.5%), including by maternal females. Deep dives often occurred in series and were characterized by U-shapes suggesting high energy expenditure. This study provides new insights into the formerly overlooked use of pelagic habitats by humpback whales during the breeding season. Given increasing anthropogenic threats on deep sea habitats worldwide, this work has implications for the conservation of vulnerable marine ecosystems.Secreted Protein Acidic and Rich in Cysteine (SPARC)-related modular calcium-binding protein-2 (SMOC2), a secreted matricellular protein, is reported to be involved in various processes related to cancer progression such as regulating the cell cycle, angiogenesis, and invasion. However, its expression and prognostic significance in papillary thyroid carcinomas (PTCs) remains unknown. Using immunohistochemistry, we evaluated the expression profile of SMOC2 and its prognostic value in a large cohort of PTCs. Real time-PCR analysis with fresh-frozen tissues showed that SMOC2 mRNA expression in PTCs was substantially lower than the expression in matched non-cancerous thyroid tissues, consistent with the results from thyroid cancer cell lines. Immunohistochemical analysis demonstrated that SMOC2 was normally present in thyroid follicular epithelial cells and the expression level was maintained in nodular hyperplasia. However, SMOC2 expression was significantly lower in lymphocytic thyroiditis and follicular tumors including follicular adenomas and carcinomas. In particular, 38% of PTCs exhibited a complete loss of SMOC2 expression, which was associated with the presence of BRAF (V600E) mutation. Moreover, SMOC2 further declined during lymph node metastasis in PTCs. DNA methylation chip analysis revealed one hypermethylated CpG site in the promoter region of SMOC2 gene, suggesting an epigenetic regulation of SMOC2 in PTCs. Remarkably SMOC2 positivity was associated with improved recurrence-free survival along with female sex, tumor size, and the N stage. However, SMOC2 was not identified as an independent prognostic marker in multivariate analyses. Taken together, SMOC2 expression is significantly down-regulated in PTCs and SMOC2 positivity is closely associated with better clinical outcomes, suggesting that SMOC2 can be a prognostic marker in PTC patients.

Although viruses must navigate the complex host endomembrane system to infect cells, the strategies used to achieve this is unclear. During entry, polyomavirus SV40 is sorted from the late endosome (LE) to the endoplasmic reticulum (ER) to cause infection, yet how this is accomplished remains enigmatic. Here we find that EMC4 and EMC7, two ER membrane protein complex (EMC) subunits, support SV40 infection by promoting LE-to-ER targeting of the virus. They do this by engaging LE-associated Rab7, presumably to stabilize contact between the LE and ER. These EMC subunits also bind to the ER-resident fusion machinery component syntaxin18, which is required for SV40-arrival to the ER. Our data suggest that EMC4 and EMC7 act as molecular tethers, inter-connecting two intracellular compartments to enable efficient transport of a virus between these compartments. https://www.selleckchem.com/products/bi-3812.html As LE-to-ER transport of cellular cargos is unclear, our results have broad implications for illuminating inter-organelle cargo transport.Stem rust is an important disease of wheat that can be controlled using resistance genes. The gene SuSr-D1 identified in cultivar 'Canthatch' suppresses stem rust resistance. SuSr-D1 mutants are resistant to several races of stem rust that are virulent on wild-type plants. Here we identify SuSr-D1 by sequencing flow-sorted chromosomes, mutagenesis, and map-based cloning. The gene encodes Med15, a subunit of the Mediator Complex, a conserved protein complex in eukaryotes that regulates expression of protein-coding genes. Nonsense mutations in Med15b.D result in expression of stem rust resistance. Time-course RNAseq analysis show a significant reduction or complete loss of differential gene expression at 24 h post inoculation in med15b.D mutants, suggesting that transcriptional reprogramming at this time point is not required for immunity to stem rust. Suppression is a common phenomenon and this study provides novel insight into suppression of rust resistance in wheat.Directed evolution of the ribosome for expanded substrate incorporation and novel functions is challenging because the requirement of cell viability limits the mutations that can be made. Here we address this challenge by combining cell-free synthesis and assembly of translationally competent ribosomes with ribosome display to develop a fully in vitro methodology for ribosome synthesis and evolution (called RISE). We validate the RISE method by selecting active genotypes from a ~1.7 × 107 member library of ribosomal RNA (rRNA) variants, as well as identifying mutant ribosomes resistant to the antibiotic clindamycin from a library of ~4 × 103 rRNA variants. We further demonstrate the prevalence of positive epistasis in resistant genotypes, highlighting the importance of such interactions in selecting for new function. We anticipate that RISE will facilitate understanding of molecular translation and enable selection of ribosomes with altered properties.The structure-specific endonuclease XPF-ERCC1 participates in multiple DNA damage repair pathways including nucleotide excision repair (NER) and inter-strand crosslink repair (ICLR). How XPF-ERCC1 is catalytically activated by DNA junction substrates is not currently understood. Here we report cryo-electron microscopy structures of both DNA-free and DNA-bound human XPF-ERCC1. DNA-free XPF-ERCC1 adopts an auto-inhibited conformation in which the XPF helical domain masks the ERCC1 (HhH)2 domain and restricts access to the XPF catalytic site. DNA junction engagement releases the ERCC1 (HhH)2 domain to couple with the XPF-ERCC1 nuclease/nuclease-like domains. Structure-function data indicate xeroderma pigmentosum patient mutations frequently compromise the structural integrity of XPF-ERCC1. Fanconi anaemia patient mutations in XPF often display substantial in-vitro activity but are resistant to activation by ICLR recruitment factor SLX4. Our data provide insights into XPF-ERCC1 architecture and catalytic activation.Little is known regarding lymph node (LN)-homing of immune cells via afferent lymphatics. Here, we show, using a photo-convertible Dendra-2 reporter, that recently activated CD4 T cells enter downstream LNs via afferent lymphatics at high frequencies. Intra-lymphatic immune cell transfer and live imaging data further show that activated T cells come to an instantaneous arrest mediated passively by the mechanical 3D-sieve barrier of the LN subcapsular sinus (SCS). Arrested T cells subsequently migrate randomly on the sinus floor independent of both chemokines and integrins. However, chemokine receptors are imperative for guiding cells out of the SCS, and for their subsequent directional translocation towards the T cell zone. By contrast, integrins are dispensable for LN homing, yet still contribute by increasing the dwell time within the SCS and by potentially enhancing T cell sensing of chemokine gradients. Together, these findings provide fundamental insights into mechanisms that control homing of lymph-derived immune cells.Idiopathic pulmonary fibrosis (IPF) is a fatal and incurable form of interstitial lung disease in which persistent injury results in scar tissue formation. As fibrosis thickens, the lung tissue loses the ability to facilitate gas exchange and provide cells with needed oxygen. Currently, IPF has few treatment options and no effective therapies, aside from lung transplant. Here we present a series of studies utilizing lung spheroid cell-secretome (LSC-Sec) and exosomes (LSC-Exo) by inhalation to treat different models of lung injury and fibrosis. Analysis reveals that LSC-Sec and LSC-Exo treatments could attenuate and resolve bleomycin- and silica-induced fibrosis by reestablishing normal alveolar structure and decreasing both collagen accumulation and myofibroblast proliferation. Additionally, LSC-Sec and LSC-Exo exhibit superior therapeutic benefits than their counterparts derived from mesenchymal stem cells in some measures. We showed that an inhalation treatment of secretome and exosome exhibited therapeutic potential for lung regeneration in two experimental models of pulmonary fibrosis.The interaction between immune cells and phosphatidylserine (PS) molecules exposed on the surface of apoptotic-tumor bodies, such as those induced by chemotherapies, contributes to the formation of an immunosuppressive tumor microenvironment (TME). Annexin A5 (AnxA5) binds with high affinity to PS externalized by apoptotic cells, thereby hindering their interaction with immune cells. Here, we show that AnxA5 administration rescue the immunosuppressive state of the TME induced by chemotherapy. Due to the preferential homing of AnxA5 to the TME enriched with PS+ tumor cells, we demonstrate in vivo that fusing tumor-antigen peptide to AnxA5 significantly enhances its immunogenicity and antitumor efficacy when administered after chemotherapy. Also, the therapeutic antitumor effect of an AnxA5-peptide fusion can be further enhanced by administration of other immune checkpoint inhibitors. Our findings support the administration of AnxA5 following chemotherapy as a promising immune checkpoint inhibitor for cancer treatment.

The cutoff value for the number of CAC sites for predicting future CVEs was 4.5. The new and easy method accurately reflected future CVEs risk and may be clinically applicable. Few studies have examined the most frequent pediatric users of hospital services. Our objective was to determine the clinical diagnoses, demographic characteristics, and medical severity of high-use pediatric patients in Canada. We conducted a retrospective analysis of patients <18 years of age who either were admitted to hospital or visited an emergency department (ED) using the Canadian Institute for Health Information's (CIHI) Dynamic Cohort of Complex, High System Users. The analysis of hospital admission data excluded Quebec and Manitoba. ED data was only available for Alberta and Ontario. 121 104 patients were identified as the most frequent hospital users and 459 998 patients as the most frequent ED users. High users were more likely to reside in a rural community, to be in a lower income quintile, and face more deprivation. The most frequent conditions for hospitalization for high use patients were disorders related to length of prematurity and fetal growth, respiratory and cardiovascular disorders specific to the perinatal period, and haemorrhagic and haematological disorders of fetus and newborn. For the most frequent ED users, the most common clinical diagnoses were acute upper respiratory infections, injuries to the head, and diseases of the middle ear and mastoid. Pediatric high users by frequency of hospital and ED services are a distinct population. Better understanding their characteristics will allow for more appropriate planning of children's health services and help identify areas for effective preventive or quality improvement initiatives. Pediatric high users by frequency of hospital and ED services are a distinct population. Better understanding their characteristics will allow for more appropriate planning of children's health services and help identify areas for effective preventive or quality improvement initiatives.[This corrects the article DOI 10.1371/journal.pone.0246312.].Quantifying the contribution of rheumatoid arthritis to the acquisition of subsequent health care costs is an emerging focus of the rheumatologic community and payers of health care. Our objective was to determine the healthcare costs before and after diagnosis of rheumatoid arthritis (RA) from the public payer's perspective. The study design was a longitudinal observational administrative data-based cohort with RA cases from Ontario Canada (n = 104,933) and two control groups, matched 11 on year of cohort entry from 2001 to 2016. The first control group was matched on age, sex and calendar year of cohort entry (diagnosis year for those with RA); the second group added medical history to the match before RA diagnosis year. The main exposure was new onset RA. The secondary exposure was calendar year of RA diagnosis to compare attributable costs over the study observation window. Main outcomes were health care costs in 2015 Canadian dollars, overall and by cost category. We used attribution methods to classify costs into those associated with RA, those associated with comorbidities, and age/sex-related underlying costs. Health care costs associated with RA increased up to the year of diagnosis, where they reached $8,591 $4,142 in RA associated costs; $1,242 in RA comorbidity associated costs; and $3,207 in underlying costs. In the eighth-year post diagnosis, the RA costs declined to $2,567 while the RA comorbidity associated costs remained relatively constant at $1,142, and the underlying age/sex related cost increased to $4,426. RA patients had lower costs when diagnosed in later calendar years. Our results suggest a large proportion of disease related health care costs are a result of costs associated with RA comorbidities, which may appear many years before diagnosis.Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo in humans, yet the molecular etiology is currently unknown. Evidence suggests that genetic factors may play an important role in some cases of idiopathic BPPV, particularly in familial cases, but the responsible genetic variants have not been identified. In this study, we performed whole exome sequencing [including untranslated regions (UTRs)] of 12 families and Sanger sequencing of additional 30 families with recurrent BPPV in Caucasians from the United States (US) Midwest region, to identify the genetic variants responsible for heightened susceptibility to BPPV. Fifty non-BPPV families were included as controls. In silico and experimental analyses of candidate variants show that an insertion variant rs113784532 (frameshift causing truncation) in the neural cadherin gene PCDHGA10 (protocadherin-gamma A10) is an exceedingly strong candidate (p = 1.80x10-4 vs. sample controls; p = 5.85x10-19 vs. ExAC data; p = 4.9x10-3 vs. NHLBI exome data). The mutant protein forms large aggregates in BPPV samples even at young ages, and affected subjects carrying this variant have an earlier onset of the condition than those without [average 44.0±14.0 (n = 16) versus 54.4±16.1 (n = 36) years old, p = 0.054]. In both human and mouse inner ear tissues, PCDHGA10 is expressed in ganglia, hair cells and vestibular transitional epithelia. Fluorescent RNA in situ hybridization using mouse inner ear tissues shows that expression increases with age. In summary, our data show that a variant in the PCDHGA10 gene may be involved in causing or aggravating some familial cases of recurrent idiopathic BPPV.[This corrects the article DOI 10.1371/journal.pone.0213535.].On March 2019 the World Health Organization declared Coronavirus disease (COVID-19) pandemic. Several recent reports disclose that the outcome of the infection is related to age, sex and can be influenced by underlying clinical conditions. Parkinson's disease (PD) and other parkinsonisms are the most common chronic disease which can cause, directly or indirectly, the patient to be more exposed to other diseases, mostly respiratory system's ones. https://www.selleckchem.com/products/Staurosporine.html Our primary outcome is to evaluate if PD patients are more susceptible than non-PD to take COVID-19 infection. Second, to detect if the infection course is worse in PD-COVID+ patients versus non-PD. This is a retrospective observational study on a cohort of 18 patients (13 PD- 5 non-PD), hospitalized in a Rehabilitative Unit during the occurrence of SARS-CoV2 epidemic outbreak. All patients performed laboratory tests, lung Computed Tomography (CT) and have been tested for COVID-19 thorough pharyngeal swab. PD and non-PD groups were comparable for age, gender and Hoehn and Yahr stage.

5. Taken together, the data suggested kallikrein to play a key role in PM2.5-induced airway hyperresponsiveness, and that it could be a potential therapeutic target in asthma. To decipher the Cd hyperaccumulation and tolerance mechanisms of plants and increase phytoremediation efficiency, in this study, the physiological effects induced by environmentally relevant concentrations (0, 25 and 200 mg/kg) of Cd were characterized in Amaranthus hypochondriacus (K472) at three growth stages using LC/MS-based metabolomics. https://www.selleckchem.com/products/bzatp-triethylammonium-salt.html Metabolomic analysis identified 31, 29 and 30 significantly differential metabolites (SDMs) in K472 exposed to Cd at the early, intermediate and late stages of vegetative growth, respectively. These SDMs are involved in nine metabolic pathways responsible for antioxidation, osmotic balance regulation, energy supplementation and the promotion of metabolites that participate in phytochelatin (PC) synthesis. K472 at the intermediate stage of vegetative growth had the strongest tolerance to Cd with the combined action of Ala, Asp and Glu metabolism, purine metabolism, Gly, Ser and Thr metabolism and Pro and Arg metabolism. Among these crucial metabolic biomarkers, purine metabolism could be the primary regulatory target for increasing the Cd absorption of K472 for the restoration of Cd-contaminated soil. Caseahomopene A (1), a rare natural product with a ring-expanded homotriterpenoid skeleton, was isolated from the leaves of Casearia kurzii. The structure including the absolute configuration was determined by spectroscopic data and X-ray crystallography analysis. Compound 1 showed anti-inflammatory effects in vitro and in vivo using LPS-stimulated cell and zebrafish model. As a potential anti-inflammatory agent, the anti-inflammatory mechanism of 1 was also investigated. A phytochemical investigation to obtain bioactive substances as lead compounds or agents for cancer led to the obtainment of six new and two known clerodane diterpenoids from the leaves of Casearia kurzii. Their structures were elucidated using NMR techniques and electronic circular dichroism (ECD) calculations. The subsequent biological cytotoxicity evaluation of these isolates toward human lung cancer A549, human cervical cancer HeLa, human chronic myeloid leukemia K562, and human hepatocellular carcinoma HepG2 was carried out. The most active compound 4 with an IC50 value of 9.7 μM against HepG2 cells was selected to examine the cytotoxic mechanism, which induced the apoptosis and arrested the HepG2 cell cycle at S stage. The in vivo zebrafish experiments revealed that compound 4 had the property of inhibiting tumor proliferation and migration. Per- and polyfluoroalkyl substances (PFASs) contamination in the Bohai Sea and its surrounding rivers has attracted considerable attention in recent years. However, few studies have been conducted regarding the distribution of PFASs in multiple environmental media and their distributions between the suspended particles and dissolved phases. In this study, surface water, surface sediment, and air samples were collected at the Bohai Sea to investigate the concentration and distribution of 39 targeted PFASs. Moreover, river water samples from 35 river estuaries were collected to estimate PFAS discharge fluxes to the Bohai Sea. The results showed that total ionic compound (Σi-PFASs) concentrations ranged from 19.3 to 967 ng/L (mean 125 ± 152 ng/L) in the water and 0.70-4.13 ng/g dw (1.78 ± 0.76 ng/g) in surface sediment of the Bohai Sea, respectively. In the estuaries, Σi-PFAS concentrations were ranged from 10.5 to 13500 ng/L (882 ± 2410 ng/L). In the air, ΣPFAS (Σi-PFASs + Σn-PFASs) concentrations ranged from 199 to 678 pg/m3 (462 ± 166 pg/m3). Perfluorooctanoic acid (PFOA) was the predominant compound in the seawater, sediment, and river water; in the air, 82 fluorotelomer alcohol was predominant. Xiaoqing River discharged the largest Σi-PFAS flux to the Bohai Sea, which was estimated as 12,100 kg/y. Some alternatives, i.e., 62 fluorotelomer sulfonate acid (62 FTSA), hexafluoropropylene oxide dimer acid (HFPO-DA), and chlorinated 62 polyfluorinated ether sulfonic acid (Cl-62 PFESA), showed higher levels than or comparable concentrations to those of the C8 legacy PFASs in some sampling sites. The particle-derived distribution coefficient in seawater was higher than that in the river water. Using high resolution mass spectrometry, 29 nontarget emerging PFASs were found in 3 river water and 3 seawater samples. Further studies should be conducted to clarify the sources and ecotoxicological effects of these emerging PFASs in the Bohai Sea area. Photothermal therapy (PTT) normally requires to maintain the temperature of tumor lesions above 50 °C, which potentially induces local inflammation and tumor metastasis. To avoid these side effects, it is vital to achieve effective antitumor efficacy at relatively low temperature (42-45 °C) during the PTT treatment. Herein, we design a polydopamine (PDA)-coated nucleic acid nanogel as a therapeutic complex for siRNA-mediated low-temperature PTT. First, siRNAs that target the heat-shock-protein 70 (Hsp70) serve as crosslinkers to guide the DNA-grafted polycaprolactone (DNA-g-PCL) assemble into nanosized hydrogel particles through nucleic acid hybridization. Thereafter, the obtained siRNA-embedded nanogels are further coated with a thin layer of polydopamine, which not only protects the nanogels against enzymatic degradation but also endows the nanogels with excellent photothermal conversion capacity under near infrared (NIR) light irradiation. After surface PEGylation, this triple shield siRNA delivery complex shows the capability of effective ablating the tumor under relatively mild condition. A penicillin G acylase (PGA) from Achromobacter xylosoxidans PX02 was newly isolated, and site-directed mutagenesis at three important positions αR141, αF142, βF24 was carried out for improving the enzymatic synthesis of β-lactam antibiotics. The efficient mutant βF24A was selected, and the (Ps/Ph)ini (ratio between the initial rate of synthesis and hydrolysis of the activated acyl donor) dramatically increased from 1.42-1.50 to 23.8-24.1 by means of the optimization of reaction conditions. Interestingly, the efficient enzymatic synthesis of ampicillin (99.1% conversion) and amoxicillin (98.7% conversion) from a high concentration (600 mM) of substrate 6-APA in the low acyl donor/nucleus ratio (1.11) resulted in a large amount of products precipitation from aqueous reaction solution. Meanwhile, the by-product D-phenylglycine was hardly precipitated, and 93.5% yield of precipitated ampicillin (561 mM) and 94.6% yield of precipitated amoxicillin (568 mM) were achieved with high purity (99%), which significantly simplified the downstream purification.

BACKGROUND AND AIM Entecavir (ETV) and tenofovir disoproxil fumarate (TDF) may reduce the risk of hepatocellular carcinoma (HCC) in chronic hepatitis B (CHB). However, it is not clear whether there is difference in the on-treatment HCC risks between ETV and TDF. METHODS In this retrospective cohort study, we compared the on-treatment HCC incidence of ETV and TDF in 1340 consecutive nucleos(t)ide analog-naïve CHB patients by propensity score (PS) matching analysis. PS was calculated by using age, sex, drinking history, diabetes, liver cirrhosis, hepatitis B e antigen positivity, hepatitis B virus DNA, hepatitis B s antigen titer, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alpha-fetoprotein, albumin, bilirubin, prothrombin time, platelet count, and calendar year of treatment initiation as covariates. The HCC risk was assessed by Cox regression with death and liver transplantation as competing risks in the 11 PS-matched cohorts (n = 596). RESULTS TDF had higher cumulative virologic response (P = 0.027) whereas ETV showed higher AST and ALT normalization rates (P = 0.005 and  less then  0.001, respectively) in PS-matched cohorts. HCC risk was similar between ETV and TDF, either by PS-matching analysis (hazard ratio [HR] for TDF over ETV = 2.06, 95% confidence interval [CI] = 0.98-4.33, P = 0.058) or inverse probability of treatment weighting analysis (HR = 1.30, 95% CI = 0.81-2.10; P = 0.276).

To investigate whether CS adjusts to increasing water deficit, variation in stem water content (StWC) was monitored in vivo for 2 years and related to periodical measurements of tree water potential in Mediterranean Quercus ilex trees subjected either to permanent throughfall exclusion (TE) or to control conditions. Seasonal reductions in StWC were larger in TE trees relative to control ones, resulting in greater seasonal CS (154 and 80 kg m-3 MPa-1 , respectively), but only during the first phase of the desorption curve, when predawn water potential was above -1.1 MPa. Below this point, CS decreased substantially and did not differ between treatments ( less then 20 kg m-3 MPa-1 ). The allometric relationship between tree diameter and sapwood area, measured via electrical resistivity tomography, was not affected by TE. Our results suggest that (a) CS response to water deficit in the drought-tolerant Q. ilex might be more important to optimize carbon gain during well-hydrated periods than to prevent drought-induced embolism formation during severe drought stress, and (b) enhanced CS during early summer does not result from proportional increases in sapwood volume, but mostly from increased elastic water. © 2020 John Wiley & Sons Ltd.BACKGROUND AND AIM The presence and severity of upper gastrointestinal mucosal lesions have not been evaluated using esophagogastroduodenoscopy (EGD) in patients receiving ticagrelor plus aspirin or alone after myocardial revascularization. We assessed upper gastrointestinal mucosal injury and the use of proton pump inhibitors (PPIs) in patients receiving 1 year of antiplatelet therapy after coronary artery bypass grafting (CABG). METHODS In this single-center prospective substudy of a randomized trial, 231 patients completing 1-year antiplatelet therapy (ticagrelor 90 mg twice daily plus aspirin 100 mg once daily, ticagrelor 90 mg twice daily, or aspirin 100 mg once daily, in 81, 80, and 70 patients, respectively) after CABG underwent 13 C urea breath testing and EGD. Gastroduodenal lesions were assessed by modified Lanza score, and reflux esophagitis was evaluated according to Los Angeles classification. Additionally, at least one ulcer ≥ 5 mm was separately analyzed. RESULTS Among 231 patients, EGD showed 28 (12.1%) with ulcers ≥ 5 mm, which were detected in 13.6% (11/81) of ticagrelor plus aspirin recipients, 8.8% (7/80) of ticagrelor recipients, and 14.3% (10/70) of aspirin recipients, and 24 (10.4%) had reflux esophagitis. Eighty-eight (38.1%) patients had a positive 13 C urea breath testing after 1 year of treatment, and one patient received eradication therapy during follow up. Nineteen (8.2%) patients received a PPI for ≥ 6 months. CONCLUSIONS Severe upper gastrointestinal mucosal lesions were more frequently observed in patients treated with ticagrelor plus aspirin and aspirin monotherapy than in patients treated with ticagrelor monotherapy for 1 year post-CABG. Prophylactic use of PPIs might be inadequate. © 2020 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.BACKGROUND & AIMS Hepatocellular carcinoma (HCC) is associated with high malignancy rates. Recently, a known deacetylase SIRT1 is discovered in HCC, while its presence is positively correlated with malignancy and metastasis. N6 -methyladenosine (m6 A) is the most prominent modification but the exact mechanisms on how SIRT1 regulates m6 A modification to induce hepatocarcinogenesis remain unclear. APPROACH & RESULTS Here we demonstrate that SIRT1 exerts oncogenic role by downregulating fat mass and obesity-associated protein (FTO), which is an m6 A demethylase. A crucial component of small ubiquitin-related modifiers (SUMOs) E3 ligase, RANBP2, is activated by SIRT1 and it is indispensable for FTO SUMOylation at Lysine (K)-216 site that promotes FTO degradation. https://www.selleckchem.com/products/PCI-24781.html Moreover, Guanine nucleotide-binding protein G (o) subunit alpha (GNAO1) is firstly identified as m6 A downstream targets of FTO and tumor suppressor in HCC, and depletion of FTO by SIRT1 improves m6 A+ GNAO1 and downregulates its mRNA expression. CONCLUSIONS We demonstrate an important mechanism whereby SIRT1 destabilizes FTO, steering the m6 A+ of downstream molecules and subsequent mRNA expression in HCC tumorigenesis. Our findings uncover a novel target of SIRT1 for therapeutic agents to treat HCC. This article is protected by copyright. All rights reserved.

The objectives of the present study were to characterize GNE-947 for its phosphoinositide 3-kinase (PI3K) and mammalian target of rapamycin (mTOR) inhibitory activities, in vitro anti-cell migration activity in Human Umbilical Vein Endothelial Cells (HUVEC), in vivo anti-neovascularization activity in laser induced rat choroidal neovascular (CNV) eyes, pharmacokinetics in rabbit plasma and eyes, and ocular distribution using Matrix-Assisted Laser Desorption Ionization Imaging mass spectrometry (MALDI-IMS) and autoradioluminography. Its PI3K and mTOR Ki were 0.0005 µM and 0.045 µM, respectively, and its HUVEC IC50 was 0.093µM. GNE-947 prevented neovascularization in the rat CNV model at 50 or 100 µg/eye with repeat dosing. Following a single intravenous injection at 2.5 and 500 μg/kg in rabbits, its plasma terminal half-lives (t1/2) were 9.11 and 9.59 hours, respectively. Following a single intravitreal injection of a solution at 2.5 μg/eye in rabbits, its apparent t1/2 values were 14.4, 16.3, and 23.2 hours it with t1/2 less than a day. However, the duration following intravitreal dose of a suspension is very long with t1/2 up to six months due to its low solubility and slow dissolution process. These results indicate that intravitreal injection of a suspension formulation for low solubility drugs can be used to achieve long-term drug exposure potentially useful for the treatment of wet AMD and other retinal diseases. https://www.selleckchem.com/products/heptadecanoic-acid.html The American Society for Pharmacology and Experimental Therapeutics.BACKGROUND Monoclonal antibodies of anti-epidermal growth factor receptor (EGFR) have been recommended as first-line therapy for patients with left-sided metastatic colorectal cancer (mCRC) with wild-type RAS. The effect of tumour laterality on antivascular endothelial growth factor antibody and how to optimise targeted therapies for the right-sided cases remain controversial. PATIENTS AND METHODS A comprehensive meta-analysis enrolling 16 first-line clinical trials was performed to evaluate the efficacy of chemotherapy alone and chemotherapy plus targeted therapies for patients with mCRC with right primary tumour site, and we validated the results in metastatic setting (14 trials containing 4306 patients with unresectable mCRC). RESULTS Here, we found that progression-free survival (PFS) (combined HR 1.30, 95% CI 1.17 to 1.44) and overall survival (OS) (combined HR 1.46, 95% CI 1.32 to 1.62) of the right-sided patients were significantly inferior to the left-sided individuals receiving chemotherapy alone in s with right-sided mCRC. © Author (s) (or their employer(s)) 2020.

PATIENTS AND METHODS A total of 210 consecutive patients who were surgically diagnosed with PTC were included in this study. Synchronous nodules, divided into probably benign and suspicious nodules based on US findings, were correlated with pathologic results using a nodule-by-nodule analysis. RESULTS Among the 302 synchronous nodules in 129 patients, 83 (27.5%) synchronous nodules in 73 patients were diagnosed as malignant after surgery. Ipsilateral probably benign nodules on US were more likely to be malignant than contralateral probably benign nodules (ipsilateral, 10.6%; contralateral, 2.0%, p=0.015). The presence of suspicious contralateral nodules on US and the number of synchronous nodules were significant factors related to contralateral cancer (p less then 0.001 and 0.030). CONCLUSION For evaluation of synchronous nodules in PTC patients, US assessment for synchronous nodules can be applied for preserving the contralateral lobe. BACKGROUND/AIM To validate the effect of treatment intensification on survival in esophageal squamous cell carcinoma (ESCC) patients undergoing definitive concurrent chemoradiotherapy (dCCRT). PATIENTS AND METHODS We reviewed the medical records of 73 ESCC patients who underwent dCCRT between 2006 and 2017 in 3 institutions. RESULTS The median follow-up time was 13.3 months. The median overall survival (OS) and locoregional recurrence-free survival (LRFS) were 13.3 and 11.2 months, respectively. The median radiotherapy dose was 55.8 Gy, and the median biologically effective dose (BED) was 65.8 Gy. Chemotherapy was given in all patients during dCCRT, and adjuvant chemotherapy was administered in 56 patients (76.7%). Adjuvant chemotherapy improved OS (3-year, 24.2% vs. 11.8%, p=0.004). Higher BED ≥70 Gy improved LRFS (3-year, 41.7% vs. 23.6%, p=0.035). CONCLUSION The addition of chemotherapy after dCCRT improves OS. A higher radiotherapy dose improved LRFS, but not OS. Adjuvant chemotherapy should be considered after dCCRT for better outcomes. BACKGROUND Brain metastases from breast cancer have poor prognosis and are a challenge to treat. Multiple treatment options are available. Descriptive and prognostic data on breast cancer brain metastases is limited. PATIENTS AND METHODS This study analyzed clinical data of patients who underwent surgical resection of one or more brain metastases. Histological and clinical characteristics, as well as treatment modalities, were analyzed. RESULTS Initial tumor stage or grade was found not to correlate with the median time to developing brain metastases or survival. Human epidermal growth factor receptor 2 (HER2)-positive status was not associated with shorter median time to developing brain metastases. No correlation was found between the number of brain metastases and patient outcome. Results confirm the survival benefit of surgical resection with or without irradiation. CONCLUSION Data showed that patients with HER2-positive and those with triple-negative breast cancer develop brain metastases at lower stages but not earlier after diagnosis, and survival is mostly dependent on treatment modality rather than histological subtype. BACKGROUND/AIM Esophagectomy is a major surgical procedure associated with a significant risk of morbidity and mortality that has traditionally been performed by an open approach. Although minimally invasive procedures for benign esophageal disease have been widely accepted worldwide, they have not yet been established for the treatment of malignancy. PATIENTS AND METHODS A total of 137 consecutive hybrid esophagectomies for cancer were performed by the same surgical team. Surgical approach included either 2-stage or 3-stage hybrid minimally-invasive esophagectomy. RESULTS Median age of patients was 64 years. Respiratory complication and anastomotic leak rates were 16.78% and 9.48%, respectively. Median follow-up was 48 months with median overall survival and disease free survival were 58 and 48 months, respectively. CONCLUSION Advances in minimally invasive surgery can benefit patients with esophageal cancer, mainly by reducing post-operative respiratory complications. Hybrid esophagectomy is safe and feasible in tertiary esophago-gastric centers with vast expertise that can lead to improved clinical and oncological outcomes.

Social interactions are a crucial aspect of human behaviour. Numerous neurophysiological studies have focused on socio-cognitive processes associated with the so-called theory of mind-the ability to attribute mental states to oneself and others. Theory of mind is closely related to social intelligence defined as a set of abilities that facilitate effective social interactions. Social intelligence encompasses multiple theory of mind components and can be measured by the Four Factor Test of Social Intelligence (the Guilford-Sullivan test). However, it is unclear whether the differences in social intelligence are reflected in structural brain differences. During the experiment, 48 healthy right-handed individuals completed the Guilford-Sullivan test. T1-weighted structural MRI images were obtained for all participants. Voxel-based morphometry analysis was performed to reveal grey matter volume differences between the two groups (24 subjects in each)-with high social intelligence scores and with low social intelligence scores, respectively. Participants with high social intelligence scores had larger grey matter volumes of the bilateral caudate. The obtained results suggest the caudate nucleus involvement in the neural system of socio-cognitive processes, reflected by its structural characteristics.Floral stickiness is a rare trait with unknown function, but it is common in the mega-diverse Cape genus Erica (Ericaceae). This study investigated the role of stickiness measured as adhesive strength in Erica as protection against nectar robbing and its correlation with floral traits. We compared the incidence of nectar robbing in flowers of the same species with or without experimentally added stickiness, and amongst communities of co-occurring species with flowers differing in stickiness. Additionally, we tested the relationship between stickiness and pollination syndrome, corolla shape, corolla length and sepal-corolla ratio across the whole genus. Stickiness was correlated with lower floral damage rates within and between species, indicating it functions as an anti-nectar robbing trait. Across the genus Erica, stickiness is most strongly correlated with bird and long-proboscid fly pollination, presumably because of their larger nectar rewards. Stickiness was also correlated with floral traits that are often associated with high risk of being damaged by nectar robbers narrow-mouthed corollas, long corollas and shorter sepals. These results show that corolla stickiness defends Erica flowers against nectar robbing and thereby potentially improves fitness. We examined associations between the 2010 Affordable Care Act (ACA) provisions, 2011 Advisory Committee on Immunization Practices (ACIP) recommendation, and 2014 ACA-related health insurance reforms with HPV vaccine initiation rates by sex and health insurance type. Using 2009-2015 public and private health insurance claims for 551,764 males and females aged 9-26years (referred to as youth) from Maine, New Hampshire, and Massachusetts, we conducted linear regression models to examine the associations between three policy changes and HPV vaccine initiation rates by sex and health insurance type. In 2009, HPV vaccine initiation rates for males and females were 0.003 and 0.604 per 100 enrollees, respectively. https://www.selleckchem.com/products/Trichostatin-A.html Among males, the 2010 ACA provisions and ACIP recommendation were associated with significant increases in HPV vaccine uptake among those with private plans (0.207 [0.137, 0.278] and 0.419 [0.353, 0.486], respectively) and Medicaid (0.157 [0.083, 0.230] and 0.322 [0.257, 0.386], respectively). Among finsured males in three New England states, closing the gender gap. In contrast, females and youth with private insurance did not exhibit the same changes in HPV vaccine uptake over the study period.Using a Markov microsimulation model among hypothetical cohorts of community-dwelling older osteoporotic Japanese women with prior vertebral fracture over a lifetime horizon, we found that daily subcutaneous teriparatide for 2 years followed by weekly oral alendronate for 8 years was not cost-effective compared with alendronate monotherapy for 10 years. Teriparatide has proven efficacy in reducing osteoporotic fractures, but with substantial cost. We examined the cost-effectiveness of sequential teriparatide/alendronate (i.e., daily subcutaneous teriparatide for 2 years followed by weekly oral alendronate for 8 years) compared with alendronate monotherapy for 10 years among community-dwelling older osteoporotic women with prior clinical or morphometric vertebral fracture in Japan. Using a previously validated and updated Markov microsimulation model, we obtained incremental cost-effectiveness ratios (Japanese yen [¥] (or US dollars [$]) per quality-adjusted life year [QALY]) from the perspective of a singln Japan, sequential teriparatide/alendronate was not cost-effective compared with alendronate monotherapy, even with the availability of biosimilar teriparatide. Among high-risk osteoporotic women in Japan, sequential teriparatide/alendronate was not cost-effective compared with alendronate monotherapy, even with the availability of biosimilar teriparatide.Interest in the development and promotion of clinical practice guidelines (CPGs) continues to grow in many professions. However, the potential benefits associated with CPGs are dependent upon their quality. A number of studies have shown that the quality of CPGs varies greatly. Furthermore, the quality of many of the CPGs used in health and social sciences has yet to be examined. In light of this, the aim of this study was to examine the quality of CPGs that focus on intervention and care management in mental health in Quebec. A search of Quebec regulatory bodies websites was conducted and six CPGs were included in this study. The CPGs were assessed by four trained raters using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument. Items scores and domains scores were considered to determine the quality of the six CPGs. Results show that many of the CPGs did not achieve minimum ratings for numerous quality checks. Notably, none of the CPGs were designed using a rigorous methodology, they lacked transparency throughout the development process and insufficient consideration was given to the applicability of the recommendations they included.

Blood pressure (BP) is determined by several physiological factors that are regulated by a range of complex neural, endocrine, and paracrine mechanisms. This study examined a collection of 198 human genes related to BP regulation, in the biological processes and functional prisms, as well as gene expression in organs and tissues. This was made in conjunction with an orthology analysis performed in 19 target organisms along the phylogenetic tree. We have demonstrated that transport and signaling, as well as homeostasis in general, are the most prevalent biological processes associated with BP gene orthologs across the examined species. https://www.selleckchem.com/products/TG100-115.html We showed that these genes and their orthologs are expressed primarily in the kidney and adrenals of complex organisms (e.g., high order vertebrates) and in the nervous system of low complexity organisms (e.g., flies, nematodes). Furthermore, we have determined that basic functions such as ion transport are ancient and appear in all organisms, while more complex regulatory functions, such as control of extracellular volume emerged in high order organisms. Thus, we conclude that the complex system of BP regulation evolved from simpler components that were utilized to maintain specific homeostatic functions that play key roles in existence and survival of organisms.Seafood products are highly perishable, owing to their high water activity, close to neutral pH, and high content of unsaturated lipids and non-protein nitrogenous compounds. Thus, such products require immediate processing and/or packaging to retain their safety and quality. At the same time, consumers prefer fresh, minimally processed seafood products that maintain their initial quality properties. The present article aims to review the literature over the past decade on (i) innovative, individual packaging technologies applied to extend the shelf life of fish and fishery products, (ii) the most common combinations of the above technologies applied as multiple hurdles to maximize the shelf life of seafood products, and (iii) the respective food packaging legislation. Packaging technologies covered include Modified atmosphere packaging; vacuum packaging; vacuum skin packaging; active food packaging, including oxygen scavengers; carbon dioxide emitters; moisture regulators; antioxidant and antimicrobial packaging; intelligent packaging, including freshness indicators; time-temperature indicators and leakage indicators; retort pouch processing and edible films; coatings/biodegradable packaging, used individually or in combination for maximum preservation potential.Cellulose paper has been functionalized by nanoparticles such as Ag nanoparticles, TiO2, and BaTiO3 for versatile applications including supercapacitor, sensors, photoactivity, and packaging. Herein, zinc oxide (ZnO) nanosheet-modified paper (ZnO@paper) with excellent antibacterial properties was fabricated via a mild ZnCl2-urea eutectic solvent. In this proposed method, cellulose fibers as the raw material for ZnO@paper were treated by an aqueous solvent of ZnCl2-urea; the crystalline region was destroyed and [ZnCl]+-based cations were adsorbed on the surface of cellulose fibers, facilitating more ZnO growth on ZnO@paper. A flexible paper-based triboelectric nanogenerator (P-TENG) was made of ZnO@paper paired with a PTFE film. The P-TENG presents high triboelectric output performance and antibacterial activity. For instance, the output voltage and current of the P-TENG were 77 V and 0.17 μA, respectively. ZnO@paper showed excellent antibacterial activity against E. coli and S. aureus, suggesting that a P-TENG can restrain and kill the bacteria during the working process. The results also indicated that ZnO could improve the surface roughness of cellulose paper, enhancing the output performance of a flexible P-TENG. In addition, the potential application of a P-TENG-based pressure sensor for determining human motion information was also reported. This study not only produced a high-performance P-TENG for fabricating green and sustainable electronics, but also provides an effective and novel method for ZnO@paper preparation.The tumorigenic potential of mouse polyomavirus (MPyV) has been studied for decades in cell culture models and has been mainly attributed to nonstructural middle T antigen (MT), which acts as a scaffold signal adaptor, activates Src tyrosine kinases, and possesses transforming ability. We hypothesized that MPyV could also transform mouse cells independent of MT via a Toll-like receptor 4 (TLR4)-mediated inflammatory mechanism. To this end, we investigated the interaction of MPyV with TLR4 in mouse embryonic fibroblasts (MEFs) and 3T6 cells, resulting in secretion of interleukin 6 (IL-6), independent of active viral replication. TLR4 colocalized with MPyV capsid protein VP1 in MEFs. Neither TLR4 activation nor recombinant IL-6 inhibited MPyV replication in MEFs and 3T6 cells. MPyV induced STAT3 phosphorylation through both direct and MT-dependent and indirect and TLR4/IL-6-dependent mechanisms. We demonstrate that uninfected mouse fibroblasts exposed to the cytokine environment from MPyV-infected fibroblasts upregulated the expressions of MCP-1, CCL-5, and α-SMA. Moreover, the cytokine microenvironment increased the invasiveness of MEFs and CT26 carcinoma cells. Collectively, TLR4 recognition of MPyV induces a cytokine environment that promotes the cancer-associated fibroblast (CAF)-like phenotype in noninfected fibroblasts and increases cell invasiveness.Food-grade titanium dioxide (TiO2) containing a nanoparticle fraction (TiO2 NPs -nanoparticles) is widely used as a food additive (E171 in the EU). In recent years, it has increasingly been raising controversies as to the presence or absence of its harmful effects on the gastrointestinal microbiota. The complexity and variability of microbiota species present in the human gastrointestinal tract impede the assessment of the impact of food additives on this ecosystem. As unicellular organisms, bacteria are a very convenient research model for investigation of the toxicity of nanoparticles. We examined the effect of TiO2 (three types of food-grade E171 and one TiO2 NPs, 21 nm) on the growth of 17 strains of lactic acid bacteria colonizing the human digestive tract. Each bacterial strain was treated with TiO2 at four concentrations (60, 150, 300, and 600 mg/L TiO2). The differences in the growth of the individual strains were caused by the type and concentration of TiO2. It was shown that the growth of a majority of the analyzed strains was decreased by the application of E171 and TiO2 NPs already at the concentration of 150 and 300 mg/L.
