Graphical Abstract Physicochemical characteristics of particle-based carriers influence their peritoneal residence time, biological fate and anticancer efficacy after intraperitoneal administration.Metal complexes were obtained by the reaction of zinc, cadmium and mercury(II) salts with Schiff base HL (N(salicylidene)benzylamine). HL was synthesized by the condensation reaction of benzylamine and 2-hydroxybenzaldehyde. The fluorescence properties of the Schiff base and its metal complexes were studied in ethanol-water solutions. HL was examined for its utility as a fuorescent chemosensor for the determination of Zn2+, Cd2+ and Hg2+ in aqueous samples. The HL chemosensor was found to be sensitive to Zn2+, Cd2+ and Hg2+ than some metal ions and its complexes emitted strong fluorescence at 452 nm for Zn2+ at 474 nm for Cd2+ and at 491 nm for Hg2+, respectively. It was determined that HL forms complexes with a ratio of 21 for Zn2+ and Hg2+ and with a ratio of 11 for Cd2+ by Job plots. For the detection of Zn2+, Cd2+ and Hg2+ in aqueous samples, pH, solvent type and ligand concentration were optimized for an analytical method based on HL chemosensor. HL gave a wide range of linearity with Zn2+, Hg2+ and Cd2+, the limit of detection was found to be 2.7 × 10-7 M, 7.5 × 10-7 M and 6.0 × 10-7 M, respectively.A significant challenge concerning the development of fluorescence lifetime (FL) based pH sensors is the paucity of fluorophores with sufficiently large FL variation with pH. Acridine is amongst the indicators with highest fluoresce lifetime responses to pH, with a change in lifetime of about 13 ns within a pH range of 5-8. Here we examine the two acridine derivatives, 9-acridinemethanamine (9-AMA) and acridine-9-carbaldehyde (9-ACA) in terms of their FL pH sensitivity and pH sensing range. Both indicators are characterized when dissolved in buffer solutions, as well as when immobilized in support materials. 9-AMA has a change in FL of 11 ns between pH 2-5, both when dissolved in solution and when immobilized in surfactant-filled mesoporous silica. The FL of 9-ACA is not sensitive to pH when dissolved in buffer solutions; however, when covalently bound to amine-modified silica, its FL changes 15 ns between pH 3-6. 9-AMA and 9-ACA represent promising FL in the pH range of pH 2-6, and could potentially form the basis of new FL pH sensors. Graphical Abstract.Dendrobium officinale is a rare and endangered perennial herb in China, which have been used in preparing Chinese tonic medicine for hundreds of years. The severe shortage of this herb and high price have caused that many similar plants were processed as an adulterant and it became difficult to distinguish genuine D. officinale by traditional authentication methods. A sensitive, convenient, and specific method for rapid identification of D. officinale is urgently needed. In the present study, 3D front-face fluorescence technique merged with Independent Component Analysis was used to get the "pure" independent fluorescence signals. The overall 3D-FFF spectra were decomposed into seven independent components (IC). https://www.selleckchem.com/products/sn-001.html To distinguish D. officinale from other species, IC1 and IC4 were chosen as fluorescence markers and the fluorescence intensity (FI) value at 340 nm/ 442 nm (excitation /emission wavelength) of IC1and 315 nm/ 468 nm of IC4 were used to build a linear model for identifying D. officinale successfully. Compared with other Dendrobium species, D. officinale showed much higher FI1 and FI4 value which is a direct criterion for identification. Meanwhile, even though the FI values of D. officinale may fluctuate due to the difference of growing conditions, the relation between FI1 and FI4 amazingly always fit the linear model constructed (FI4 = 9.9046 + 0.6119FI1, R2 = 0.9811). The linear model is an important finding and specific for D. officinale. Based on the FI value and the goodness of fit in the linear model, D. officinale can be identified quickly.Based on boron-dipyrromethene (BODIPY), taking 2-hydroxy-N-(2-hydroxyphenyl)benzamide as recognition site, a new fluorescent probe HHPBA-BODIPY aimed at sensitively detecting Cu ions was designed, synthesized and characterized.The emission spectra of HHPBA-BODIPY exhibited an intensive green fluorescence around 510 nm, with a maximum absorption near 500 nm. When Cu2+ ions are present, the fluorescence at 510 nm can be quenched with a good linearity between the copper ion concentrationand the fluorescence intensity and the detection limit is 0.35 μM. HHPBA-BODIPY is also selective toward Cu2+, while other metal ions show no interfere except Fe3+ and Cr3+ ions. In addition, HHPBA-BODIPY also proved efficient to detect Cu2+ in water samples which offers the possibility to detect trace amount of Cu2+ for environmental monitoring. Copper ions; BODIPY; fluorescent probe.The absorption and fluorescence spectra of synthesized 4-[5-(2,5-Dimethyl-pyrrol-1-yl)-[1, 3, 4] thiadiazol-2-ylsulfanylmethyl]-6-methoxy-chromen-2-one (DTYMC) compound were recorded in various solvents like acetone, acetonitrile, chloroform, dimethyl formamide (DMF),1,4-dioxane, ethanol, ethyl acetate, methanol, tetrahydrofuran (THF) and dimethylsulphoxide (DMSO) at room temperature in order to estimate the ground and excited state dipole moment. The ground state dipole moment (μg) and excited state dipole moment (μe) were calculated using solvatochromic shift method which involve equations proposed by Lippert, Bakshiev and Kawski-Chamma-Viallete. The results were signified that the excited state dipole moment is greater than the ground state dipole moment, which indicates the excited state is more polar than the ground state of the molecule. The bond angle between the ground state and excited state dipole moments were found to be 00, The change in dipole moment (∆μ) was calculated using microscopic solvent polarity parameter ([Formula see text]). Further multiple linear regression analysis of Kamlet-Taft parameter, HOMO-LUMO energy were determined by cyclic voltammetry using phosphate buffer solution.In this study, we developed two different very sensitive magnetite fluorescent Fe3O4@SiO2-TPED-BODIPY and Fe3O4@SiO2-TMPTA-BODIPY nano-sensors for the selective detection of Cr(VI) ions. The Cr(VI) metal ions sensing is based on the fluorescent quenching of BODIPY functionalized with Fe3O4@SiO2-TPED and Fe3O4@SiO2-TMPTA nanoparticles in the ethanol-water environment. Characterization of the newly synthesized fluorescent BODIPY compound was performed on a 1H and 13C-NMR spectrometer. The morphology, chemical and physical properties of the sensing nano-sensors were studied by transmission thermogravimetric analysis (TGA), X-ray diffraction (XRD), energy dispersive X-ray (EDX), scanning electron microscopy (SEM), FT-IR spectroscopy, and transmission electron microscopy (TEM). UV-visible and fluorescent spectroscopy were used to characterize BODIPY functionalized magnetite fluorescent nano-sensors. Characterization measurements revealed that the mean particle diameter of magnetite fluorescent Fe3O4@SiO2-TPED-BODIPY and Fe3O4@SiO2-TMPTA-BODIPY nano-sensors was 18.

The aim of this study was to assess the reliability, durability, and safety of this procedure as the definitive treatment for complex, chronically infected TKA, in a current series of patients. Methods We retrospectively identified 41 patients (41 TKAs) with a complex infected TKA, who were treated between 2002 and 2016 using a deliberate, two-stage knee arthrodesis. Their mean age was 64 years (34 to 88) and their mean body mass index (BMI) was 39 kg/m2 (25 to 79). The mean follow-up was four years (2 to 9). The extensor mechanism (EM) was deficient in 27 patients (66%) and flap cover was required in 14 (34%). Most patients were host grade B (56%) or C (29%), and limb grade 3 (71%), according to the classification of McPherson et al. A total of 12 patients (29%) had polymicrobial infections and 20 (49%) had multi-drug resistant on (32%). This is not surprising as this series included worst-case infected TKAs in which two-thirds of the patients had a disrupted EM, one-third required flap cover, and most had polymicrobial or multi-drug resistant organisms.

Methods A group of 156 knees (134 F22 M) in 133 patients with a mean age 75.8 years (SD 6.4) who underwent TKA with the cruciate-substituting Bi-Surface Knee prosthesis were retrospectively enrolled. On lateral radiographs, γ angle (the angle between the distal femoral axis and the line perpendicular to the distal rear surface of the femoral component) was measured, and the patients were divided into four groups according to the γ angle. The 2011KSSs among groups were compared using the Kruskal-Wallis test. A secondary regression analysis was used to investigate the association between the 2011KSS and γ angle. Results According to the mean and SD of γ angle (γ, 4.0 SD 3.0°), four groups (Extended or minor flexed group, -0.5° ≤ γ 8.5° showed inferior clinical outcomes in 2011KSSs. Secondary regression analyses showed that mild flexion of the femoral component was associated with the highest score. When implanting the Bi-Surface Knee prosthesis surgeons should pay careful attention to avoiding flexing the femoral component extensively during TKA. Our findings may be applicable to other implant designs.

In the present study, to explore the role of autocrine factors in embryo self-spent culture media, we prospectively compared embryo transfer with self-spent culture medium and fresh medium on clinical pregnancy outcomes. A total of 318 fresh IVF/intracytoplasmic sperm injection (ICSI) cycles were randomly allocated into two subgroups based on their transfer media (using a self-spent culture medium or new pre-equilibrated culture media), and the clinical outcomes were compared between groups. The implantation rates, clinical pregnancy rates and live birth rates for transfer using self-spent medium instead of new pre-equilibrated culture medium were slightly improved without statistical significance. Interestingly, however, biochemical pregnancy rate was found to be significantly decreased after transfer using self-spent medium for Day 3 embryos compared with new pre-equilibrated culture media. In short, embryo transfer with self-spent culture medium has shown some advantages, and large sample size studies are still needed to confirm these observations.

Design Double-blind multicenter randomized trial. Participants People with multiple sclerosis of 18 to 60 years, Expanded Disability Status Scale ⩽6.0, mild to moderate cognitive impairment. Interventions They were randomized into cognitive rehabilitation program (ProCog-SEP) or in a placebo program. ProCog-SEP comprises 13 group's sessions over 6 months and includes psychoeducational advices and cognitive exercises. Placebo program included non-cognitive exercises. No strategy and no cognitive advice were provided. Main measures The primary endpoint was the percentage of verbal memory learning measured by the Selective Reminding Test. A comprehensive neuropsychological assessment is carried out before and after interventions by a neuropsychologist blinded to intervention. Effectiveness of the ProCog-SEP versus Placebo has been verified using linear regression models. Results In total, 128 participants were randomized and 110 were included in the study after planning session in groups; 101 completed this trial (77.2% females); mean age 46.1 years (±9.6); disease duration 11.8 years (±7.5). ProCog-SEP was more effective in increasing in learning index (9.21 (95% confidence interval (CI) 1.43, 16.99); p = 0.02) and in working memory on manipulation (0.63 (95% CI 0.17, 1.09); p = 0.01), and updating capacities (-1.1 (95% CI -2.13, -0.06); p = 0.04). No difference was observed for other neuropsychological outcomes. Regarding quality of life outcomes, no change was observed between the two groups. Conclusion These findings suggest that ProCog-SEP could improve verbal learning abilities and working memory in people with multiple sclerosis. https://www.selleckchem.com/products/mln2480.html These improvements were observed with 13 group sessions over 6 months.

Here, we present the findings on the effect of the continuous release of 2ccPA from the capsule to reduce the lysophospholipase D activity and also decrease plasma levels of lysophosphatidic acid in rat. These findings will be useful in further studies for evaluating the application of 2ccPA in several disorders. OBJECTIVE To explore the unified and disease specific structural features of the brain in patients spanning six mental disorders who experience own-thought auditory verbal hallucinations (OTAVH). METHODS A pilot study was conducted on 25 patients with schizophrenia (FUSCH-OTAVH), 20 patients with major depression disorder (FUMDD-OTAVH), 28 patients with bipolar disorder (FUBD-OTAVH), 22 patients with posttraumatic stress disorder (FUPTSD-OTAVH), 21 patients with anxiety disorder (FUAD-OTAVH), and 27 patients with borderline personality disorder (FUBPD-OTAVH). Twenty-five healthy controls (HCs) were also recruited. Auditory Hallucinations Rating Scale (AHRS) multiple psychometric scales were adopted to assess the clinical features of voxel-based morphometry (VBM), tract-based spatial statistics (TBSS), and multiple regression in all patients. Common and specific brain features of OTAVH among these mental disorders were investigated. RESULTS Compared to HCs, GMV aberrant pattern across all the six categories patients with OTAVH decreased in the occipital cortex, left parietal lobe, prefrontal cortex (PFC), and insular cortex (IC). Aberrant patterns in white matter (WM) were detected in the corpus callosum and impairment of the fronto-occipital fasciculus. Structural differences in the brain were observed for each mental disorder versus HCs CONCLUSIONS The unified brain aberrant features of OTAVH across six mental disorders were characterized by decreased GMV and WM impairments in some regions and the specific brain features of each disease were also characterized. In conclusion, this study provides evidence for the structural basis of OTAVH and potential avenues for investigating disease specific brain features of OTAVH. Constraint-induced movement therapy (CIMT) has proven to be an effective way to restore functional deficits following stroke in human and animal studies, but its underlying neural plasticity mechanism remains unknown. Accumulating evidence indicates that rehabilitation after stroke is closely associated with synaptic plasticity. We therefore investigated the impact of CIMT on synaptic plasticity in ipsilateral and contralateral brain of rats following stroke. Rats were subjected to 90 minutes of transient middle cerebral artery occlusion (MCAO). CIMT was performed from 7 days after stroke and lasted for two weeks. Modified Neurology Severity Score (mNSS) and the ladder rung walking task tests were conducted at 7,14 and 21 days after stroke. Golgi-Cox staining was used to observe the plasticity changes of dendrites and dendritic spines. The expression of glutamate receptors (GluR1, GluR2 and NR1) were examined by western blot. Our data suggest that the dendrites and dendritic spines are damaged to varying degrees in bilateral sensorimotor cortex and hippocampus after acute stroke. CIMT treatment enhances the plasticity of dendrites and dendritic spines in the ipsilateral and contralateral sensorimotor cortex, increases the expression of synaptic GluR2 in ipsilateral sensorimotor cortex, which may be mechanisms for CIMT to improve functional recovery after ischemic stroke. OBJECTIVE An unexpected promising effect of low-molecular-weight heparins (LMWHs) on survival in cancer patients was observed in early trials in post-hoc subgroup analyses but not found in more recent trials. In order to highlight a possible regression over time toward the lack of antitumoral effect of LMWHs, we performed a cumulative meta-analysis of survival data from RCTs. STUDY DESIGN AND SETTING Medical databases were searched to identify randomized clinical trials comparing LMWHs to placebo or no treatment in cancer patients without VTE, or to VKA in cancer patients with VTE in overall survival. Cumulative hazard ratio (HR) was estimated after each study inclusion in chronological order. RESULTS Twenty-three studies (12,970 patients) were included. https://www.selleckchem.com/products/ITF2357(Givinostat).html The cumulative meta-analysis of the earlier trials showed a significant improvement in overall survival with LMWHs. This apparent benefit then gradually regressed over time toward an absence of effect of LMWHs on survival(HR 0.98 [95% CI, 0.93; 1.03]). CONCLUSION Despite supportive experimental data and early clinical findings, the promising antitumor effect of LMWHs in cancer patients gradually vanished over time toward a lack of impact on overall survival. This result suggests 'p-hacking' and selective reporting of positive results from post-hoc subgroup analyses in the early studies. OBJECTIVES The fragility of clinical trial findings has been previously defined as the number of changes in outcomes that are required to change their statistical significance. We show that reliance on statistical significance alone provides only a limited and potentially misleading perspective, and an enhanced approach is developed. METHODS Clinical importance of trial results and their quantitative stability are incorporated into an enhanced framework to assess fragility. RESULTS Examples show that the small data changes required to affect statistical significance may actually be unlikely to occur. Recognising this limitation, and because statistical significance conveys no information about the treatment effect size, our approach additionally takes into account the clinical importance of the results, and their quantitative stability. The interpretation of studies with various combinations of these features is described. CONCLUSION The concept of fragility should include clinical importance of trial findings and their quantitative stability, as well as statistical significance. Study results should be declared as stable only if they are statistically significant and quantitatively stable, but they can be either clinically important or unimportant; otherwise the findings should be declared as unstable, or fragile.

Hierarchical Co3O4@MnOx material has been synthesized by in-suit growth of MnOx on the Co3O4 and applied in catalytic oxidation of volatile organic compounds (VOCs). Results revealed that T90 of acetone on the Co3O4@MnOx was 195 °C, which was 36 °C and 32 °C lower than that on the Co3O4 and MnOx/Co3O4, respectively. The universality experiments demonstrated that T90 of ethyl acetate and toluene on the Co3O4@MnOx were 200 °C and 222 °C, respectively. The above results indicated that Co3O4@MnOx catalyst presented a robust catalytic performance. Characterization results showed that high catalytic activity of the Co3O4@MnOx catalyst could be attributed to the improvement of low temperature reducibility, the enhancement of Co3+ and adsorbed oxygen species resulted from the sufficient reaction between MnO4- and Co2+ during secondary hydrothermal process. Furthermore, stability and water-resistance experiments showed the Co3O4@MnOx catalyst with high cycle and long-term stability, satisfied endurability to 5.5-10 vol. % water vapor at 210 °C. Fluidized bed bioreactors can overcome the limitations of packed bed bioreactors such as clogging, which has been observed in the industrial application for decades. The key to establish a gaseous fluidized bed bioreactor for treatment of volatile organic compounds is to achieve microbial growth on a light packing material. https://www.selleckchem.com/products/bpv-hopic.html In this study, Two fungal species and two bacterial species were isolated to build a fungal fluidized-bed reactor (FFBR). A light packing material with wheat bran coated on expended polystyrene was used. The FFBR was operated for 65 days for gaseous ethanol removal and obtained elimination capacities of 500-1800 g∙m-3∙h-1 and removal efficiencies of 20-50%. The pressure drops was well controlled with values around 400 Pa∙m-1. Stress tolerant genera including Aureobasidium, Stenotrophomonas and Brevundimonas were dominant. Meyerozyma, whose species were present in an initial inoculated isolate, was detected among the dominant species with 28.70% relative abundance; they were reported to degrade complicated compounds under similarly stressful environments. The speciation and mobility of As are controlled by both Fe and Mn (oxyhydr)oxides through a series of surface complexation and redox reactions occurring in the environment, which is also complicated by the solution chemistry conditions. However, there is still a lack of quantitative tools for predicting the coupled kinetic processes of As reactions with Fe and Mn (oxyhydr)oxides. In this study, we developed a quantitative model for the coupled kinetics of As adsorption/desorption and oxidation in ferrihydrite-Mn (oxyhydr)oxides and ferrihydrite-Mn(II)-O2 systems. This model also accounted for the variations in solution chemistry conditions and binding site heterogeneity. Our model suggested that Mn (oxyhydr)oxide and ferrihydrite mainly served as an oxidant and an adsorbent, respectively, when they coexisted. Among the three types of binding sites of ferrihydrite, the adsorbed As(V) was mainly distributed on the nonprotonated bidentate sites. Our model quantitatively showed that the oxidation rates of different reaction systems varied significantly. The rates of As(III) oxidation were enhanced with higher pH values and higher molar ratios of Mn(II)/As(III) in the ferrihydrite-Mn(II)-O2 system. This study provides a modeling framework for predicting the kinetic behavior of As when multiple adsorption/desorption and oxidation reactions are coupled in the environment. Stable and long-term power output is a prerequisite for the application of the energy recovered from microbial fuel cells (MFCs). In this study, a novel fuel supplying strategy based on slow-release carbon embedded in polymer gels was attempted in MFCs aimed to achieve a sustainable power generation. Polymer gels containing starch acetate as the carbon source (40% (w/w)) were prepared, and the effects of its loading dosage on power generation and microbial community structure were investigated. Results showed that the MFCs once fed with 20.0 g/L, 37.5 g/L and 55.0 g/L polymer gels attained a long-term power generation periods of 110, 140 and 170 days, respectively, with a maximum power density of 386-427 mW/m2. The MFC with a medium loading dosage (37.5 g/L polymer gels) performed best. MFCs fed with the slow-release carbon enriched a distinct microbial community comparing to the control MFC with acetate as the carbon source, with the genera Geobacter, Sphaerochaeta, Christensenellaceae, Aminiphilus and Proteiniphilum significantly enriched on the anode electrode, and Sphaerochaeta, Proteiniphilum and Bacteroidetes in the anolyte. This carbon source providing method will promote the application of MFCs as a sustainable and stable power source for environmental monitoring and remediation. To achieve efficient biological nutrients removal at low temperature, a modified sequencing batch reactor (SBR) was developed at 10 °C by extending sludge retention time (SRT), shortening aerobic stage and compensating anoxic stage. The average removal rates of ammonium (NH4+-N), total nitrogen (TN) and total phosphorus (TP) were 98.82%, 94.12% and 96.04%, respectively. Variation of carbon source in a typical cycle demonstrated the maximum synthesis of poly-β-hydroxybutyrate (PHB) (60 mg/L) occurred after feast period. Furthermore, the TP in sludge reached 50.4 mg/g mixed liquor suspended solids (MLSS) (78.4% was inorganic phosphorus and 21.6% was organic phosphorus) after 120 days of operation, indicating an excellent P-accumulating capacity was achieved in this system. Ammonia oxidizing bacteria (AOB) activity inhibition test verified both AOB and ammonia oxidizing archaea (AOA) were involved in ammonia-oxidizing process and the latter accounted for 17%-19%. Metagenomic-based taxonomy revealed the dominant genera were Candidatus Accumulibacter (12.18%), Dechloromonas (7.54%), Haliangium (6.69%) and Candidatus Contendobacter (3.40%). As described from the denitrifying genes perspective, with the exception of nitrite reduction (performed by denitrifiers), denitrifying phosphorus-accumulating organisms (DPAOs) played a leading role in denitrification pathway, showing that poly-β-hydroxyalkanoates (PHA)-driven nutrients removal was the dominate process.

In contrast, lower FBS concentrations (5 and 10%) improved all post-thaw variables when compared to control. Afterwards, based on regression analysis, the concentration of 7% FBS was chosen to be assessed against CLCs in an experiment composed by four groups control, FBS, CLCs, and FBS + CLCs. FBS and FBS + CLCs groups exhibited higher progressive motility in fresh samples, whereas only FBS maintained higher post-thaw progressive motility. Additionally, the incorporation FBS into extenders increased the percentage of rapid cells and reduced free radicals production and plasma membrane peroxidation. Together, these outcomes indicated that FBS minimize some harmful effects of cryopreservation, providing an alternative for chicken semen extenders that in many aspects appears to be superior to CLCs at 1 mg/mL.Background The recent identification of embryo cell-free DNA in the spent blastocyst media opened a new era of possibilities for non-invasive embryo aneuploidy testing in assisted reproductive technologies. Yet, previous studies assessing limited numbers of embryos reported variable concordance between embryo cell-free DNA and trophectoderm biopsies, thus questioning the validity of this approach. Objective(s) 1) To evaluate the concordance and reproducibility of testing embryo cell-free DNA versus trophectoderm DNA obtained from the same embryo in a large sample of human blastocysts. 2) To assess the contribution of the inner cell mass and/or trophectoderm to the embryo cell-free DNA released to the culture media. Study design This is the interim analysis of a prospective, observational study among eight in vitro fertilization centers, on four continents, to assess consistency between non-invasive embryo aneuploidy testing of embryo cell-free DNA and conventional trophectoderm biopsy. Analysis included 1,301vantages such as avoiding invasive embryo biopsy and decreased cost, potentially increasing accessibility for a wider patient population.Recent surveys have shown widespread lapses in the procedures used to reduce the risk of transmitting infection via medical devices. Transvaginal ultrasound examination has the potential to transmit vaginal infections, including human papillomavirus (HPV). Areas of particular concern are the use of probe covers with high rates of leakage, use of disinfectants that are not effective against HPV, and use of coupling gel from multiple-use containers. We review these issues and recommend four steps to reduce the risk of transmitting infection. First, during every transvaginal ultrasound exam, the probe should be covered with a sterile, single-use "viral barrier" cover or a condom. Second, sterile, single-use ultrasound gel packets should be used. Third, after every examination, the probe should be cleaned to remove any visible gel or debris. Fourth, after cleaning, the probe should undergo high-level disinfection using an agent with proven efficacy against HPV, including hydrogen peroxide, hypochlorite, or peracetic acid. Glutaraldehyde, ortho-phthalaldehyde, phenols, and isopropyl alcohol have virtually no efficacy against HPV.Background A majority of women in the United States with gestational diabetes mellitus (GDM) do not undergo the recommended 4-12 week post-partum glucose tolerance test (GTT). Objective To compare the diagnostic value of the 2-day postpartum GTT during the delivery hospitalization to the 4-12 week post-partum GTT in identifying impaired glucose metabolism 1 year post-partum STUDY DESIGN Post-partum women who delivered at one hospital between January 2017 and July 2018 were offered enrollment in a prospective cohort if they had GDM diagnosed by Carpenter Coustan criteria or a 1-hour glucose challenge test >200 mg/dl, spoke English or Spanish, and planned to remain in-hospital until at least 2 days post-partum. Participating women underwent a 75-gram 2-hour GTTs on post-partum day 2 and were incentivized to have a 4-12 week GTT and measurement of glycosylated hemoglobin (HgbA1c) 1 year post-partum. Participants and providers were blinded to the 2-day post-partum results. The diagnostic value of an abnormal 2-dafference in the 2-day compared to the 4-12 week GTT for identifying diabetes at one year post-partum. Both the 2 day and 4-12 week GTTs had similar ROC curves for identifying impaired glucose metabolism and diabetes at 1 year post-partum. Conclusion GTTs 2 days post-partum have similar diagnostic value as 4-12 weeks post-partum GTTs for predicting impaired glucose metabolism and diabetes 1 year post-partum and are associated with nearly 100% adherence to the test. Thus, changing the timing of the GTT should be considered.Plant-based ingredients are successfully replacing fishmeal in fish feeds. However, this practice increases the risk of feed contamination by mycotoxins that reduce production and heath associated with oxidative damage. The aim of this study was to determine whether feed contaminated with environmentally relevant concentrations of ochratoxin A (OTA) causes muscle oxidative damage in tambaqui (Colossoma macropomum), and to determine whether this feed impairs fatty acid profiles in fish meat. Final mean weight, weight gain, daily weight gain, feed efficiency, and specific growth rate were significantly lower in fish fed 1.6 and 2.4 mg OTA/kg compared to those fed basal diet, while feed conversion was significantly higher in these same groups compared to the basal group. Levels of reactive oxygen species and lipid peroxidation in muscle were significantly higher in fish fed 1.6 and 2.4 mg OTA/kg compared to those in the basal group. Likewise, muscle superoxide dismutase and glutathione peroxidase activities were significantly higher in fish fed 1.6 and 2.4 mg OTA/kg then in those fed basal feed. The total content of saturated fatty acids was significantly higher, and total content of polyunsaturated fatty acids was significantly lower in fish fed 2.4 mg OTA/kg compared to those fed basal feed. https://www.selleckchem.com/products/AZD6244.html Taken together, the data suggest that OTA-contaminated feed induces oxidative damage and disturbs enzymatic and non-enzymatic antioxidant responses in tambaqui meat. The perturbations of fatty acid profiles in fish meat appears to mediated by oxidative damage, representing negative impact on fish health and presenting concerns for consumers of fish.

Concerns included the lack of Pap screenings and prescriptions written for the wrong birth control. Within most student characteristics or attitudes assessed, at least 70% of the students would use this service. Based on student opinions, female college students would use pharmacists prescribing birth control services.In China, red pandas (Ailurus fulgens) have been raised in zoos for 60 years. It is very important to understand the genetic diversity and population genetic structure of the captive red pandas. Based on 19 microsatellite loci, we investigated genetic diversity and population genetic structure of 116 captive red pandas, with samples taken from 11 captive populations in China. Our results revealed a high genetic diversity among the populations, with mean allelic richness varying from 3.505 (Beijing) to 4.026 (Mianning), and expected heterozygosities varying from 0.631 (Huangshan) to 0.782 (Wenling). In particular, significant deviation from Hardy-Weinberg equilibrium was found in populations of Fuzhou and Jiangsu. The genetic differentiation index across all populations was 0.055, indicating a significant genetic differentiation among the 11 populations. These populations could be divided into three genetic clusters using a microsatellite-based Bayesian clustering analysis, which were consistent with the clustering results of wild populations. We conclude that the genetic diversity among captive red pandas is as high as that of the wild population. More attention should be paid to develop a proper and scientifically-based management program to avoid inbreeding and maintain a high genetic diversity in captive red pandas.Heavy metal ion contamination in water poses a significant risk to human health as well as to the environment. Millions of tons of agricultural wastes are produced from oil palm plantations which are challenging to manage. In this study, we converted palm kernel shells (PKS) from a palm oil plantation into activated carbon (AC) having a surface area of 1099 m2/g using phosphoric acid as an activator. The prepared material was characterized using BET, XRD, Raman, FESEM and FTIR analyses. The AC was applied for the treatment of heavy-metal-contaminated water, and different parameters; the pH, adsorbent dosage, contact time and metal ion concentrations were varied to determine the optimal conditions for the metal ion adsorption. Different kinetic models; the zeroth, first-order and second-order, and Freundlich and Langmuir isotherm models were used to determine the mechanism of metal ion adsorption by the AC. Under the optimized conditions, Cr6+ and Pb2+ were removed completely, while Zn2+ and Cd2+ were more than 80% removed. This is a greener approach in which an agricultural waste, PKS is converted into a useful product, activated carbon and subsequently applied for the treatment of heavy metal-contaminated water.Abscisic acid (ABA) is a hormone with a very long evolutionary history, dating back to the earliest living organisms, of which modern (ABA-producing) cyanobacteria are likely the descendants, well before separation of the plant and animal kingdoms, with a conserved role as a signal regulating cell responses to environmental challenges. In mammals, nanomolar ABA controls the metabolic response to glucose availability by stimulating glucose uptake in skeletal muscle and adipose tissue with an insulin-independent mechanism and increasing energy expenditure in the brown and white adipose tissues. Activation by ABA of AMP-dependent kinase (AMPK), in contrast to the insulin-induced activation of AMPK-inhibiting Akt, is responsible for stimulation of GLUT4-mediated muscle glucose uptake, and for the browning effect on white adipocytes. Intake of micrograms per Kg body weight of ABA improves glucose tolerance in both normal and in borderline subjects and chronic intake of such a dose of ABA improves blood glucose, lipids and morphometric parameters (waist circumference and body mass index) in borderline subjects for prediabetes and the metabolic syndrome. This review summarizes the most recent results obtained in vivo with microgram amounts of ABA, the role of the receptor LANCL2 in the hormone's action and the significance of the endowment by mammals of two different hormones controlling the metabolic response to glucose availability. Finally, open issues in need of further investigation and perspectives for the clinical use of nutraceutical ABA are discussed.Neurotensin subtype 1 receptors (NTS1R) represent attractive molecular targets for directing radiolabeled neurotensin (NT) analogs to tumor lesions for diagnostic and therapeutic purposes. This approach has been largely undermined by the rapid in vivo degradation of linear NT-based radioligands. Herein, we aim to increase the tumor targeting of three 99mTc-labeled NT analogs by the in-situ inhibition of two key proteases involved in their catabolism. DT1 ([N4-Gly7]NT(7-13)), DT5 ([N4-βAla7,Dab9]NT(7-13)), and DT6 ([N4-βAla7,Dab9,Tle12]]NT(7-13)) were labeled with 99mTc. Their profiles were investigated in NTS1R-positive colon adenocarcinoma WiDr cells and mice treated or not with the neprilysin (NEP)-inhibitor phosphoramidon (PA) and/or the angiotensin converting enzyme (ACE)-inhibitor lisinopril (Lis). Structural modifications led to the partial stabilization of 99mTc-DT6 in peripheral mice blood (55.1 ± 3.9% intact), whereas 99mTc-DT1 and 99mTc-DT5 were totally degraded within 5 min. Coinjection of PA and/or Lis significantly stabilized all three analogs, leading to a remarkable enhancement of tumor uptake for 99mTc-DT1 and 99mTc-DT5, but was less effective in the case of poorly internalizing 99mTc-DT6. https://www.selleckchem.com/products/blu-285.html In conclusion, NEP and/or ACE inhibition represents a powerful tool to improve tumor targeting and the overall pharmacokinetics of NT-based radioligands, and warrants further validation in the field of NTS1R-targeted tumor imaging and therapy.Used lubricant oils (ULOs) strongly bind to soil particles and cause persistent pollution. In this study, soil microcosm experiments were conducted to model the ex situ bioremediation of a long term ULO-polluted area. Biostimulation and various inoculation levels of bioaugmentation were applied to determine the efficacy of total petrol hydrocarbon (TPH) removal. ULO-contaminated soil microcosms were monitored for microbial respiration, colony-forming units (CFUs) and TPH bioconversion. Biostimulation with inorganic nutrients was responsible for 22% of ULO removal after 40 days. Bioaugmentation using two hydrocarbon-degrader strains Rhodococcus quingshengii KAG C and Rhodococcus erythropolis PR4 at a small inoculum size (107 CFUs g-1 soil), reduced initial TPH concentration by 24% and 29%, respectively; the application of a higher inoculum size (109 CFUs g-1 soil) led to 41% and 32% bioconversion, respectively. After 20 days, all augmented CFUs decreased to the same level as measured in the biostimulated cases, substantiating the challenge for the newly introduced hydrocarbon-degrading strains to cope with environmental stressors.

ssion glucagon-like peptide 1 level can discriminate hospital-acquired infections-free survival and predict long-term mortality in a group of patients with burn injury. Our data suggests that glucagon-like peptide 1 may be a predictive biomarker for hospital-acquired infections and mortality in burn patients. BACKGROUND/PURPOSE Choledochal cysts are congenital dilations of the bile ducts, and are associated with an increased risk of malignant transformation. The purpose of this study is to report the outcomes of a large series of patients with choledochal cysts and to highlight our analysis of one patient who developed malignancy after cyst resection. METHODS We conducted a retrospective review of patients less then 18 years of age with a choledochal cyst who underwent surgical resection between 1995 and 2018. Molecular testing of resected choledochal cyst specimens using the UCSF500 gene panel was performed on three patients including a 3-month-old boy and a 7-year-old girl who have remained cancer-free, and a 16-year-old girl who subsequently developed cholangiocarcinoma less than two years after resection. RESULTS One patient of the 48 included in our study developed cholangiocarcinoma after choledochal cyst resection. We observed de novo somatic mutations in TP53 and RBM10, and KRAS amplification in this patient's tumor. CONCLUSIONS In our series, the rate of malignancy after choledochal cyst resection was low. One patient developed de novo mutations in the remnant bile ducts after cyst resection. While it is a rare occurrence, the risk of malignancy following cyst resection supports the need for lifelong surveillance. LEVEL OF EVIDENCE IV. INTRODUCTION The composition and relative abundance of bacterial species change throughout the development of dental caries; however, how these changes relate to clinical symptoms remains elusive. In this study, we explored the relationship between clinical symptoms and specific microorganisms in advanced dentinal caries. METHODS A total of 111 permanent premolars and molars were used to simulate the progression from caries to pulpitis indirectly. Clinical symptoms were evaluated, and teeth were diagnosed according to the diagnostic criteria of the American Association of Endodontics. Samples were collected for 16S ribosomal DNA sequencing. Associations between the microbiota and clinical symptoms/diagnosis and the relationship between alpha diversity and clinical symptoms/diagnosis were evaluated independently by the linear discriminant analysis effect size and Spearman rank correlation analyses. RESULTS The 16S ribosomal DNA sequences were assigned to 13,852 operational taxonomic units. The linear discriminant analysis effect size and Spearman correlations unveiled negative associations between the relative abundance of Bacteroidia and Gammaproteobacteria and referred pain, Gammaproteobacteria and the electric pulp test response, and Actinomyces and Propionibacterium and diagnosis (r .05). CONCLUSIONS Clinical symptoms and diagnosis were significantly associated with specific microorganisms in the most advanced layers of dentinal caries. INTRODUCTION Cone-beam computed tomographic (CBCT) imaging is useful in detecting apical periodontitis, which is often missed in periapical (PA) radiographs. This study aimed to identify preoperative predictors correlated with the presence of apical periodontitis visible only in CBCT images and to investigate the important characteristics of such lesions. METHODS In total, 332 consecutive patients with both PA radiographs and CBCT images were enrolled in this study. The patients' clinical charts were reviewed retrospectively to collect information regarding their symptoms and diagnoses. Periapical lesions were assessed using a modified CBCT PA index by 2 endodontists. Patient-related factors (age, sex, and symptoms) and tooth-related factors (tooth type, location, pulp status, and pulpal diagnosis) were assessed to determine their relationships with the presence of apical periodontitis visible only in CBCT images. RESULTS Apical periodontitis was detected in 24.6% and 35.5% of untreated teeth by PA radiographs and CBCT images, respectively. In a multivariate logistic regression analysis, pulp necrosis was significantly correlated with the presence of apical periodontitis visible only in CBCT images (odds ratio = 5.401; 95% confidence interval, 1.911-15.265; P = .001); the involvement of molars showed borderline nonsignificant correlation (odds ratio = 2.843; 95% confidence interval, 0.990-8.164; P = .052). Lesion sizes smaller than 2 mm in diameter and the involvement of molars were significant factors of lesions visible only in CBCT images (P less then .05). CONCLUSIONS Pulp necrosis was a preoperative predictor of apical periodontitis visible only in CBCT images. This research could provide a proper indication for CBCT imaging at diagnostic stages. Type 1 autoimmune pancreatitis (AIP) is a kind of IgG4-related disease in which higher IgG4 and total IgG levels have been found in patient serum. Due to the similar imaging features and laboratory parameters between AIP and pancreatic ductal adenocarcinoma (PDAC), a differential diagnosis is still challenging. https://www.selleckchem.com/products/rin1.html Since IgG profiles can be potential bio-signatures for disease, we developed and validated a method which coupled on-bead enzymatic protein elution process to an efficient UHPLC-MS/MS method to determine IgG subclass and glycosylation. A stable-isotope labeled IgG was incorporated as internal standard to achieve accurate quantification. For calibration curves, the correlation coefficients for total IgG and the four IgG subclasses were higher than 0.995. Intraday (n = 5) and interday (n = 3) precisions of the peak area ratios of LLOQ, low, medium, and high QC samples were all less than 6.6% relative standard deviation (% RSD), and the accuracies were between 93.5 and 114.9%. Calibration curves, precision, and accuracy were also evaluated for 26 IgG glycopeptides. The method was applied to samples from healthy controls and patients with AIP and PDAC. Distinct IgG patterns were discovered among the groups, and 7 glycopeptides showed high potential in differentiating AIP and PDAC. The results demonstrated that the developed method is suitable for multi-feature analysis of human IgG, and the discovered IgG profiles can be used as bio-signatures for AIP and PDAC. V.

Conclusions These findings may explain some of the motor difficulties experienced by children with DCD as well as contribute to the discussion on mechanisms involved in skill learning in these children.Magnesium (Mg) is a material widely used in industrial applications due to its low weight, ductility, and excellent mechanical properties. For non-permanent implants, Mg is particularly well-suited because of its biodegradability, while its degradation products are not harmful. However, Mg is chemically reactive, and cytotoxic hydrogen gas is released as part of the degradation. This adverse degradation can be tuned using plasma electrolytic oxidation (PEO). With PEO, a surface layer of MgO/Mg(OH)2 is deposited on the surface of Mg in a controlled way. The electrolytes used during PEO influence the surface's chemistry and topography and thus expectedly the biological response of adhered cells. In this study, thin samples of commercial pure of Mg (c.p Mg) were modified by PEO guided by different electrolytes, and the biological activity was assessed on vascular cells, immune cells, and repair cells (adipose tissue-derived stromal cells, ASCs). Vascular cells were more vulnerable than ASCs for compounds released by surface-coated Mg. All surface coatings supported the proliferation of adhered ASC. Released compounds from surface-coated Mg delayed but did not block in vitro wound closure of fibroblasts monolayers. Preformed endothelial tubes were vulnerable for released compounds, while their supporting ASC was not. We conclude that PEO-based surface-coating of Mg supports adhesion and future delivery of therapeutic vascular repair cells such as ASC, but that the observed vulnerability of vascular cells for coated Mg components warrants investigations in vivo.Objective To compare outcomes, specifically development of preeclampsia with severe features (sPE), between angiogenic biomarker-based admission and admission based on routine clinical care. Study design This secondary analysis of a prospective study evaluated soluble fms-like tyrosine kinase-1 (sFlt1)/placental growth factor (PlGF) ratio in women presenting to triage for preeclampsia evaluation. Biomarkers levels were measured in samples collected from triage and analyzed retrospectively after outcomes were achieved. For this analysis patients would be hypothetically assigned to 'discharged' with a sFlt1/PlGF ratio ≤ 38 and 'admitted' with a sFlt1/PlGF ratio > 85. Development of sPE and other outcomes were then compared using the biomarker and clinical criteria for admission. Results 459 patients were included in this analysis. Using biomarker criteria, a larger proportion of patients were hypothetically discharged (67.8% vs 51.0%, p less then 0.0001). A larger proportion of patients 'admitted' with a high biomarker level developed sPE (69.5% vs 40.9%, p less then 0.0001). A sFlt1/PlGF ratio ≤ 38 had a negative predictive value of 96.8% for development of sPE within two weeks. Conclusion Assessment of angiogenic biomarkes that 'discharges' patients with a low sFlt1/PlGF ratio and 'admits' patients with high ratio could result in reduced admissions and increased admission of patients at risk for developing sPE. Randomized trials are needed to determine the effectiveness of angiogenic biomarker use in decision making in a triage setting among women with suspected preeclampsia.Objectives Airway macrophages represents a central site for the mechanisms involved in the complex interactions between environmental triggers and airway inflammation. https://www.selleckchem.com/products/tat-beclin-1-tat-becn1.html Based on anti-inflammatory activity of adiponectin, we hypothesize that adiponectin inhibits the proinflammatory cytokines production and the activation of alveolar macrophages expose to cigarette smoke. Materials and methods To examine the effects of adiponectin on alveolar macrophages, we used the cigarette smoke-induced the alveolar inflammation model in C57BL/6 mice and the macrophages activation model in vitro, both in the presence or absence of adiponectin, to assess the accumulation of inflammatory cells and the concentration of inflammatory cytokines and chemokines in the bronchoalveolar lavage (BAL), and the proinflammatory cytokines production and M1/2 phenotype in alveolar macrophages. Results Our results showed that adiponectin improves cigarette smoke-induced airway inflammation in vivo and decreases proinflammatory cytokine production and alveolar macrophages polarization in vitro. Moreover, our study further demonstrates that anti-inflammatory activity of adiponectin depends on the suppression of the proinflammatory cytokine production through TLR2/4 signaling and the inhibition of macrophage polarization vit COX-2/PGE2 signaling. Conclusions Our study suggests that the anti-inflammatory activity of adiponectin might contribute to its therapeutic potential in airway inflammation, such as COPD.Rheumatoid arthritis (RA) is a chronic, symmetric, systemic autoimmune disease. Because insufficient apoptosis of fibroblast-like synoviocytes (FLS) is an important characteristic of RA, promoting apoptosis is considered a potential therapeutic tool for treating RA. We have previously found that daphnetin (7,8-dihydroxycoumarin, DAP) has a pro-apoptotic effect on fibroblast-like synoviocytes from collagen-induced arthritis (CIA) rats. In the present study, we further investigated the mechanisms of DAP-induced apoptosis in CIA-FLS. CIA-FLS were incubated with DAP for 48 h in the presence or absence of caspase inhibitors, including inhibitors of caspase-3, caspase-8, or caspase-9 or a pan-caspase inhibitor; then, a series of experiments were performed to evaluate the mechanisms of DAP-induced apoptosis. Our results showed that DAP markedly decreased cell viability and induced the apoptosis of CIA-FLS along with typical morphological and ultrastructural changes; moreover, DAP increased FasL, cytochrome c (Cyt-c), Bax, caspase-3, caspase-8, and caspase-9 mRNA expression and Bax, caspase-3, caspase-8, and caspase-9 protein expression. In contrast, DAP decreased Bcl-2 mRNA and protein expression and promoted the release of Cyt-c from the mitochondria into the cytosol; these effects were attenuated to varying degrees by pre-treatment with caspase inhibitors, especially with caspase-3 or caspase-9 inhibitors or a pan-caspase inhibitor. In conclusion, the current findings demonstrate that the DAP-induced apoptosis of CIA-FLS occurred mainly via a caspase-dependent pathway, in particular the mitochondrial pathway, and that the Bax/Bcl-2 ratio was involved in this process. Thus, DAP may be a potential therapeutic agent for RA.

Conclusion Hydrocele affects both sperm count and motility, but it has no effects on ICSI outcomes. Clinical pregnancy rate was comparable in patients with or without hydrocele. Hence, the surgical management of hydrocele before ICSI is not recommended. Copyright © 2019 Journal of Human Reproductive Sciences.Context In in vitro fertilization (IVF) cycles, the recommended dose of recombinant human chorionic gonadotropin (r-hCG), for triggering final follicular maturation is 250 μg, although there is some disagreement. Aims The aim of our study was to assess the effect on the number of mature oocytes retrieved after triggering ovulation in IVF cycles using 250 μg or 500 μg of r-hCG. Settings and Design Prospective, single-center, randomized study. Subjects and Methods 100 women undergoing IVF with embryo transfer. The primary outcome measure was the total number of oocytes retrieved per follicle, number of mature oocytes, and number of embryos generated. The secondary outcomes included clinical and biochemical pregnancy rates and incidence of ovarian hyperstimulation syndrome. Results Mean number of oocytes retrieved (6.5 ± 4.0 vs. 6.4 ± 3.9, P = 0.3) and mean number of mature oocytes (4.0 ± 2.3 vs. 3.2 ± 2.3, P = 0.09) were similar in the two groups; however, mean number of oocytes retrieved per follicle was found to be higher with 500 μg r-hCG (67.4 ± 23.9 vs. 77.5 ± 23.3, P = 0.04). In the subgroup of poor responder women, there was a significant increase in the number of mature oocytes retrieved with double dose of r-hCG (2.2 ± 1.8 vs. 3.7 ± 1.9, P = 0.06), leading to improvement in fertilization and clinical pregnancy rates. Conclusions Double dose of r-hCG for final follicular maturation in IVF cycles resulted in improvement in mean number of oocytes per follicle but did not result in improved pregnancy rates in the women. In the subset of poor responders, 500 μg r-hCG seems to be more advantageous than the lower dose, although larger randomized trials are needed to generalize this strategy. Copyright © 2019 Journal of Human Reproductive Sciences.Context Therapeutic proteins can cause immune responses, which may have clinical implications. Aims The aim of the study was to assess the immunogenicity of recombinant human follicle-stimulating hormone (r-hFSH), when used for controlled ovarian stimulation (COS). Settings and Design Prospective, multicenter study conducted at reproductive medicine clinics in India and Vietnam. Materials and Methods A total of 285 women, aged 20-40 years, undergoing 354 COS cycles for either intrauterine insemination (IUI) or in vitro fertilization (IVF) were studied. The primary outcome measure was the incidence of development of anti-drug antibodies (ADA) and their neutralization potential. Other outcome measures were follicle development, dose and duration of r-hFSH, positive serum pregnancy test, clinical pregnancy, cycle cancellation, and adverse events (AEs). Statistical Analysis Used A sample size of 250 was planned. Descriptive statistics are presented. Results Four patients tested positive for ADA after r-hFSH administration at different time points; all of them tested negative, subsequently. None were found to have neutralization potential. The mean dose and duration of r-hFSH were 816 IU and 8.1 days in IUI and 2183 IU and 9.5 days in IVF, respectively. The serum and clinical pregnancy rates were 12.4% and 11.6% in IUI and 32.7% and 29.9% in IVF cycles, respectively. Seven AEs were reported, including two cases of ovarian hyperstimulation syndrome; two AEs were judged to be serious. Conclusions The tested r-hFSH has very low immunogenic potential and did not lead to the development of neutralizing antibodies. The overall efficacy and safety of the drug were in-line with existing literature data, and no specific clinical impact of immunogenicity could be identified.

The aim of this study was to evaluate the association between serum human fetuin-A/alpha2-Heremans-Schmid glycoprotein levels and idiopathic premature ovarian insufficiency (POI). Methods A total of 75 women were included in this case-control study between January 2013 and December 2013. Serum fetuin-A concentrations were measured in 36 women with idiopathic POI and 39 healthy women with regular cycles. https://www.selleckchem.com/products/caspofungin-acetate.html Blood samples were drawn after a 12-h overnight fast and were kept at -80°C for subsequent assay. The serum levels of fetuin-A were assessed by commercial ELISA kits (BioVendor Laboratory Medicine Inc., Brno, Czech Republic) and serum concentration values were expressed as μg/ml. Results The mean serum fetuin-A levels of idiopathic POI and control women were 229.02 ± 27.79 and 232.37 ± 65.56, respectively, with P = 0.771 (independent samples t-test). Our results showed no statistically significant difference between serum fetuin-A levels of idiopathic POI women and controls. Conclusion The mean values of serum fetuin-A in idiopathic POI women were not significantly different from controls, which implies that there is no significant association between serum fetuin-A levels and idiopathic POI. Copyright © 2019 Journal of Human Reproductive Sciences.Context In many developing countries, subfertility treatment is not covered by government-funded institutions. It is observed that healthcare providers incriminate male factor for subfertility even when only a slight deviation from presumed normal criteria is observed. Aim This study aims to provide scientific evidence that pregnancies are possible at semen parameters that are below the generally accepted lower limits of normal. Setting and Design This was a retrospective cohort study conducted from January 2014 to December 2018. Materials and Methods During the study period, couples who conceived without any treatment of male partner were included. The World Health Organization (WHO) reference values for semen analysis were utilized to assess the reports. The primary outcome measure was conception despite abnormal semen parameters. Statistical Analysis Used Data were analyzed using the SPSS software program, version 15.0 (IBM, Armonk, USA). Results Of the 332 couples included, 233 (70.1%) couples conceived despite suboptimal semen parameters, The most common criterion not satisfied was rapid linear motility -200 (85.
