80) and the lowest in group C (IRR = 0.72). When assessing "haze," there was good agreement in groups A (IRR = 0.75) and B (IRR = 0.76) but low agreement in group C (IRR = 0.37). CONCLUSIONS We report the development and evaluation of a novel method for grading results of limbal stem cell deficient eyes after treatment and provide this system as a free, open-source online tool. The grading tool offers an easy and standardized way of assessing the corneal surface in patients with LSCD, enables evaluation of progression over time, reduces assessment bias, and-if adopted universally-will harmonize outcome being reported between groups.PURPOSE Ocular exposure to sulfur mustard (SM) vapor causes acute loss of corneal endothelial cells (CECs). Persistent corneal endothelial pathologies are observed in eyes that do not recover from SM exposure, suggesting that endothelial toxicity contributes to mustard gas keratopathy (MGK). Here, we evaluated the contributions of endothelial loss to acute and chronic corneal injuries in SM-exposed eyes. METHODS Rabbit eyes were exposed in vivo to equivalent doses of SM using 9-, 11-, or 14-mm vapor caps. The effects of exposure area on corneal injury progression were longitudinally evaluated over 12 weeks using clinical evaluations. The effects of exposure area on CEC morphology, endothelial and epithelial ultrastructure, and endothelial barrier function were determined from 1 day to 12 weeks. RESULTS SM exposure caused loss of CECs and failure of endothelial barrier integrity at 1 day, independent of exposure cap size. By 3 weeks, eyes exposed with the 14-mm vapor cap exhibited increased corneal permeability, repopulation of the endothelium by cells with fibroblastic morphology, and abnormal deposition of extracellular matrix. Eyes exposed with 9- or 11-mm vapor caps exhibited transient symptoms of injury that fully resolved, with the rate of recovery correlated with cap size. CONCLUSIONS The nonlinear correlation between endothelial lesion size and probability of developing MGK suggests that the CEC loss is a determinative factor for emergence of MGK. https://www.selleckchem.com/products/nsc697923.html These studies illustrate the importance of endothelial repair in preventing MGK. Furthermore, they exclude chemical modification of basement membrane as a mechanistic cause of recurrent epithelial erosions in MGK eyes.The NTRK genes (NTRK1, NTRK2, and NTRK3) encode for TrkA, TrkB, and TrkC, neurotrophic tyrosine receptor kinases which serve a variety of functions including in the regulation of pathways involved in carcinogenesis. A number of reports have described NTRK gene fusions in a variety of adult and pediatric tumor types from various organ systems including the central nervous system, thyroid gland, breast, and soft tissue. NTRK-rearranged uterine sarcomas are a recently described group of tumors which occur in both the uterine corpus and cervix, tend to morphologically resemble fibrosarcoma, and may behave aggressively, although data is limited given the newly recognized nature and thus relative rarity of these tumors. Herein, we present the case of a cervical sarcoma with SPECC1L-NTRK3 fusion (detected with Illumina RNA Fusion Panel), prospectively diagnosed at the time of cervical biopsy and subsequently treated with hysterectomy. The clinical presentation, radiologic findings, morphologic features, and immunohistochemical profile of this case will be reviewed and compared with the body of existing literature to date. Identification of NTRK-rearranged neoplasms is important as targeted therapy in the form of NTRK inhibitors has recently become widely available.INTRODUCTION Proximal humerus fractures (PHF) are a common upper extremity fracture in the elderly cohort. An aging and more comorbid cohort, along with recent trends of increased operative intervention, suggests that there could be an increase in resource utilization caring for these patients. We sought to quantify these trends and quantify the impact that comorbidity burden has on resource utilization. METHODS Data on 83,975 patients with PHFs were included from the Premier Healthcare Claims database (2006 to 2016) and stratified by Deyo-Charlson index. Multivariable models assessed associations between Deyo-Charlson comorbidities and resource utilization (length and cost of hospitalization, and opioid utilization in oral morphine equivalents [OME]) for five treatment modalities (1) open reduction internal fixation (ORIF), (2) closed reduction internal fixation (CRIF), (3) hemiarthroplasty, (4) reverse total shoulder arthroplasty, and (5) nonsurgical treatment (NST). We report a percentage change in resourcofound effects on the cohort level and resource utilization for those with PHFs, especially because the use of bundled payment strategies for fractures increases. LEVEL OF EVIDENCE Level III.Non-alcoholic fatty liver disease is a highly prevalent medical condition, characterized by intrahepatic fat accumulation which may eventually lead to hepatic inflammation, cell death and reactive fibrosis. Obesity and metabolic disturbances constitute significant contributors to liver steatosis pathogenesis, however, there is a growing awareness that fatty liver may emerge even in normal weight or metabolically healthy individuals. In recent years, advanced imaging techniques have revealed that liver steatosis is quite common in inflammatory bowel disease patients, suggesting that intestinal inflammation and disturbances of the liver-gut axis may also play a key role in non-alcoholic fatty liver disease pathophysiology. The current review focuses on the co-occurrence of the two disorders, integrating research findings on epidemiology, clinical characteristics and common pathophysiological processes. The study of liver steatosis in inflammatory bowel disease patients may provide useful insights on the complex links between dietary fat intake, metabolic dysregulation, gut physiology and intrahepatic cellular mechanisms underlying liver inflammation and damage.INTRODUCTION The present study was conducted to compare the efficacy and side effects of Spironolactone and Eplerenone in management of ascites due to liver cirrhosis. MATERIALS AND METHODS 105 patients of ascites with liver cirrhosis were randomized into three groups of 35 patients each. Group I was given Spironolactone 100 mg, group II was given Eplerenone 100 mg and group III was given Eplerenone 50 mg. All patients were put on salt-restricted diet (less than or equal to 2 g of sodium) and no loop diuretics were used. Patients were followed after 7 days from the baseline and then biweekly for the period of three months and serial measurements of weight, abdominal girth and incidence of side effects especially gynecomastia, mastalgia, hyperkalemia were recorded. Results were compared. Patients having Child-Turcotte-Pugh score-C, massive ascites, hepatic encephalopathy, Hepatorenal syndrome and ascites due to cardiac, renal, malignant causes were excluded. OBSERVATIONS Difference in mean weight reduction was non significant (P = 0.

Development of resistance to chemo- and radiotherapy in patients suffering from advanced cervical cancer narrows the therapeutic window for conventional therapies. Previously we reported that a combination of the selective BCL-2 family inhibitors ABT-263 and A-1210477 decreased cell proliferation in C33A, SiHa and CaSki human cervical cancer cell lines. As ABT-263 binds to both BCL-2 and BCL-XL with high affinity, it was unclear whether the synergism of the drug combination was driven either by singly inhibiting BCL-2 or BCL-XL, or inhibition of both. In this present study, we used the BCL-2 selective inhibitor ABT-199 and the BCL-XL selective inhibitor A1331852 to resolve the individual antitumor activities of ABT-263 into BCL-2 and BCL-XL dependent mechanisms. A-1210477 was substituted for the orally bioavailable S63845. Four cervical cancer cell lines were treated with the selective BCL-2 family inhibitors ABT-199, A1331852 and S63845 alone and in combination using 2-dimensional (2D) and 3-dimensional (3D)ation of MCL-1-selective inhibitors with either selective inhibitors of either BCL-XL or BCL-2 may be potentially useful as treatment strategies for the management of cervical cancer. © 2020 The Authors.Early diagnosis of gastric cancer (GC) provides patients opportunities for minimally invasive endoscopic resection. Here, we developed a new strategy integrated the state-of-the-art sequential windowed acquisition of all theoretical fragment ion (SWATH) mass spectra (MS) with multi-dataset joint analysis to screen for the stage-I GC plasma biomarker. In SWATH-MS assays, we identified 37 upregulated and 21 downregulated proteins in GC plasma. In the mRNA database analysis, 633 genes were identified as differentially expressed genes in at least 4 out of 5 datasets, but there were only 94 genes identified as upregulated. Only 1 gene, CHI3L1, was characterized as upregulated in both the dataset consensus list and the SWATH-MS list. Then, we detected the CHI3L1 level in the plasma of a large cohort consisting of 200 participants. The area under the ROC curve (AUC) of CHI3L1 in distinguishing GC from others was 0.788. Integrating the plasma CHI3L1 level with clinical factors further boosted the AUC to 0.887. In conclusion, we provide a novel strategy for biomarker screening, combining recent MS techniques with public database analysis, and identified plasma CHI3L1 as a potential biomarker for patients with endoscopically resectable GC. © 2020.Lung cancer is the most common cause of cancer deaths worldwide, and lung adenocarcinoma (LUAD) is the most common histological subtype. However, the prognostic and predictive outcomes differ because of this cancer type heterogeneity. LUAD subtypes were identified on the basis of the immunogenomic profiling of 29 immune signatures. We named three LUAD subtypes Immunity High, Immunity Medium, and Immunity Low. The Immunity High subtype was characterized by immune activation, e.g., increased immune scores, elevated stromal scores and the highest infiltration of CD8+ T cells, and decreased tumor purities. Activated expressions of human leukocyte antigen (HLA) genes, immune checkpoint molecules, and T helper 1 (Th1)/interferon-gamma (IFNγ) gene signature were also observed in the Immunity High subtype. N 6-methyladenosine (m6A) RNA methylation, associated with cancer initiation and progression, was reduced in the Immunity High subtype. Functional and signaling pathway enrichment analysis further showed that differentially expressed genes between the Immunity High subtype and the other subtypes mainly participated in immune response and some cancer-associated pathways. In addition, the Immunity High subtype exhibited more sensitivity to immunotherapy and chemotherapy. Finally, candidate compounds that aimed at LUAD subtype differentiation were identified. Comprehensively characterizing the LUAD subtypes based on immune signatures may help to provide potential strategies for LUAD treatment. © 2020 The Author(s).Chimeric antigen receptor (CAR) T cell therapy has had limited efficacy for solid tumors, largely due to a lack of selectively and highly expressed surface antigens. To avoid reliance on a tumor's endogenous antigens, here we describe a method of tumor-selective delivery of surface antigens using an oncolytic virus to enable a generalizable CAR T cell therapy. Using CD19 as our proof of concept, we engineered a thymidine kinase-disrupted vaccinia virus to selectively deliver CD19 to malignant cells, and thus demonstrated potentiation of CD19 CAR T cell activity against two tumor types in vitro. In an immunocompetent model of B16 melanoma, this combination markedly delayed tumor growth and improved median survival compared with antigen-mismatched combinations. We also found that CD19 delivery could improve CAR T cell activity against tumor cells that express low levels of cognate antigen, suggesting a potential application in counteracting antigen-low escape. This approach highlights the potential of engineering tumors for effective adoptive cell therapy. © 2020 The Author(s).Glioma is the most common primary malignancy in the brain, and vasculogenic mimicry (VM) is one of the blood supply methods. Here we investigated the possibility that lncRNAs regulate the stability of transcription factors through the SMD pathway, which affects proliferation, migration, invasion, and the ability to form VMs in glioma. Expression of PABPC5, HCG15, and ZNF331 was detected by real-time qPCR or western blot in glioma. https://www.selleckchem.com/products/ly3009120.html Cell Counting Kit-8, Transwell assays, and in vitro VM tube formation were used to investigate PABPC5, HCG15, and ZNF331 function in cell proliferation, migration, invasion, and VM, respectively. ChIP assays were used to ascertain the interaction betweenZNF331 and LAMC2 or PABPC5. PABPC5 and HCG15 were highly expressed in glioma cells. ZNF331 was lowly expressed. PABPC5 bound HCG15 to increase its stability. Knockdown HCG15 reduced the degradation of ZNF331 mRNA by the SMD pathway. ZNF331 inhibited transcription through binding to the promoter region of LAMC2 and PABPC5 and inhibited the ability to form VMs in glioma cells. The PABPC5/HCG15/ZNF331 feedback loop plays an important role in regulating VM formation in glioma and provides new targets for glioma treatment. © 2020 The Authors.

Uveal effusion can lead to anterior swelling of the choroid up to angle-closure glaucoma. This article reports the case of a 57-year-old male patient who presented with headache, vertigo and bilaterally reduced visual acuity. The examination showed a myopic shift and angle-closure glaucoma caused by uveal effusion. The medical history revealed that 3 days before the appearance of the symptoms, treatment with chlorthalidone was added to the antihypertensive medication. After discontinuation of the chlorthalidone intake the uveal effusion and its concomitant symptoms disappeared without residues.Natural killer (NK) cells are critically involved in anti-tumor immunity by targeting tumor cells. In this study, we show that intratumoral NK cells from NSCLC patients expressed elevated levels of the immune checkpoint receptor PD-1 on their cell surface. In contrast to the expression of activating receptors, PD-1+ NK cells co-expressed more inhibitory receptors compared to PD-1- NK cells. Intratumoral NK cells were less functional compared to peripheral NK cells, and this dysfunction correlated with PD-1 expression. Tumor cells expressing PD-L1 inhibited the functionality of PD-1+ NK cells in ex vivo models and induced PD-1 clustering at the immunological synapse between NK cells and tumor cells. Notably, treatment with PD-1 blockade was able to reverse PD-L1-mediated inhibition of PD-1+ NK cells. Our findings highlight the therapeutic potential of PD-1+ NK cells in immune checkpoint blockade and could guide the development of NK cell-stimulating agents in combination with PD-1 blockade.Clostridioides difficile infection (CDI) is one of the most common causes of nosocomial diarrhea in developed countries and the main cause in healthcare settings. This case-control study was designed to evaluate the composition of the gut microbiota dominant bacterial groups in patients with CDI compared to the healthy control subjects. A total of 100 adult subjects involving 50 inpatients with CDI and 50 healthy persons were enrolled in the study. C. https://www.selleckchem.com/products/epz005687.html difficile isolates were characterized according to the anaerobic culture and presence of toxin genes with multiplex PCR. An ecological analysis was performed real-time quantitative PCR for bacterial elements. The abundances of Enterococcus spp., Lactobacillus spp., Escherichia coli, C. difficile, and Akkermansia muciniphila were higher in group CDI compared with group HC (P  less then  0.05). The abundances of Bacteroides spp., Bifidobacterium spp., and Faecalibacterium prausnitzii were lower in group CDI than in group HC (P  less then  0.05). No significant difference was observed in the copy number of Prevotella genus between the CDI and HC subjects (P-value = 0.087). We observed that economic status and income levels were reduced at patients with CDI, however, there was no significant difference between CDI and HC group results and other variables, such as age, BMI, and educational level. These findings showed a reduction in butyrate-producing bacteria and increase in lactic acid-producing bacteria was seen in CDI status. Overrepresentation of Akkermansia may be a predictive marker for the development of nosocomial diarrhea can result in a worse CDI prognosis.Early diagnosis and targeted preemptive antifungal treatment are crucial in reducing cryptococcal meningitis (CM)-related mortality in individuals living with human immunodeficiency virus (HIV). The present study was performed to determine cryptococcal antigenemia and outcomes among HIV-infected patients in Iran. This multicenter prospective study was conducted between October 2016 and December 2018. For the purpose of the study, blood samples were randomly collected from 177 profoundly immunosuppressed (CD4+ counts  less then  200 cells/µL) HIV-positive individuals in six major cities of Iran. The patients were antiretroviral therapy-naive or had received inadequate medication. The stored sera were screened for cryptococcal antigen (CrAg), using point-of-care lateral flow assay (IMMY® diagnostics, Norman, OK, US). Overall, out of the 174 asymptomatic patients, 3 (1.72%) cases were CrAg-positive using the LFA in serum. Accordingly, the prevalence of cryptococcal antigenemia was 7.14%, 0%, and 1.2% in the patients with the CD4+ counts of  less then  50, 50-100, and 100-200 cells/μL, respectively. The median age of the patients with antigenemia was 36 years (age range 8-55 years). The median CD4+ count of the cohort was 98 cells/μL (range 14-200 cells/μL). Routine screening of Iranian HIV-infected patients with CD4+ count of less then 50 cells/µL before initiating antiretroviral therapy is justified. It is suggested to conduct more inclusive research throughout the whole country on more patients to recommend screening cryptococcal antigen strongly.The article "The Bacterial Population of Neutral Mine Drainage Water of Elizabeth's Shaft (Slovinky, Slovakia)", written by Jana Kisková, Zuzana Perháèová, Ladislav Vlèko, Jana Sedláková, Simona Kvasnová and Peter Pristaš, was originally published electronically on the publisher's internet portal on 12 March 2018 without open access.

It is approved in combination with dexamethasone as first-line therapy for transplant-ineligible patients with NDMM, and as maintenance treatment following autologous stem cell transplantation (ASCT). Although strong clinical trial evidence has supported the integration of lenalidomide into current treatment paradigms for NDMM, applying those paradigms to individual patients and determining which patients are most likely to benefit from lenalidomide treatment are more complex. In this paper, we utilize the available clinical trial evidence to provide recommendations for patient selection and lenalidomide dosing in both the first-line setting in patients ineligible for ASCT and the maintenance setting in patients who have undergone ASCT. In addition, we provide guidance on management of those adverse events that are most commonly associated with lenalidomide treatment, and consider the optimal selection and sequencing of next-line agents following long-term frontline or maintenance treatment with lenalidomide.

BACKGROUND Longevity and population growth generate an increase in the number of people with dependency, who require homecare assistance to meet their health needs. Homecare support workers provide this care in Spain, and they may have unique insights into the unmet health needs of those receiving homecare assistance. The aim of this study was to determine the unmet health needs of people with dependency based on the perspective of homecare support workers. METHODS Qualitative exploratory-descriptive study. Through convenience sampling, homecare support workers from a Spanish province were selected, following inclusion and exclusion criteria. Four focus groups, transcription and thematic analyses were performed using Atlas.ti. Coding triangulation was carried out, applying criteria for scientific rigour. RESULTS The six themes obtained were classified into the material, psychoemotional, socioeconomical and psychosocial needs of people with dependency from the point of view of homecare support workers, along with the contributions of improvements and the need of these professionals for continuous training. CONCLUSIONS People with dependency need complex technical assistance, materials, psychological attention due to their situation, and more effective assessments of their health and disability status. Homecare support workers perceive themselves to be essential in these assessments. They ask for psychological assistance, due to the emotional burden of their work, and believe this help would contribute to improving the quality of their service. Homecare support workers perceive that they are capable of performing their job, although they believe that some delegated activities are beyond their levels of competency.High-cis polydicyclopentadiene (PDCPD) aerogels were synthesized using ring opening metathesis polymerization (ROMP) of dicyclopentadiene (DCPD) with a relatively air-stable ditungsten catalytic system, Na[W2(-Cl)3Cl4(THF)2]·(THF)3 (W2; (W 3 W)6+, a΄2e΄4), and norbornadiene (NBD)as a co-initiator. These aerogels are compared in terms of chemical structure and material properties with literature PDCPD aerogels obtained using well-established Ru-based alkylidenes as catalysts. The use of NBD as a co-initiator enhances the degree of crosslinking versus the more frequently used phenylacetylene (PA), yielding materials with a controlled molecular structure that would persist solvent swelling. Indeed, those PDCPD aerogels absorb selected organic solvents (e.g., chloroform, tetrahydrofuran) and swell rapidly, in some cases up to 4 times their original volume within 10 min, thus showing their potential for applications in chemical sensors and solvent-responsive actuators. The advantage of aerogels versus xerogels or dense polymers for these applications is their open porosity, which provides rapid access of the solvent to their interior, thus decreasing the diffusion distance inside the polymer itself, which in turn accelerates the response to the solvents of interest.Biopsy is the standard for assessment of bone marrow involvement in mantle cell lymphoma (MCL). We investigated whether [18F]FDG-PET radiomic texture features can improve prediction of bone marrow involvement in MCL, compared to standardized uptake values (SUV), and whether combination with laboratory data improves results. Ninety-seven MCL patients were retrospectively included. SUVmax, SUVmean, SUVpeak and 16 co-occurrence matrix texture features were extracted from pelvic bones on [18F]FDG-PET/CT. A multi-layer perceptron neural network was used to compare three combinations for prediction of bone marrow involvement-the SUVs, a radiomic signature based on SUVs and texture features, and the radiomic signature combined with laboratory parameters. This step was repeated using two cut-off values for relative bone marrow involvement REL > 5% (>5% of red/cellular bone marrow); and REL > 10%. https://www.selleckchem.com/products/azd4573.html Biopsy demonstrated bone marrow involvement in 67/97 patients (69.1%). SUVs, the radiomic signature, and the radiomic signature with laboratory data showed AUCs of up to 0.66, 0.73, and 0.81 for involved vs. uninvolved bone marrow; 0.68, 0.84, and 0.84 for REL ≤ 5% vs. REL > 5%; and 0.69, 0.85, and 0.87 for REL ≤ 10% vs. REL > 10%. In conclusion, [18F]FDG-PET texture features improve SUV-based prediction of bone marrow involvement in MCL. The results may be further improved by combination with laboratory parameters.The use of edible biopolymers and natural additives obtained from food processing by-products is a sustainable strategy for food packaging applications. Gelatin is a biopolymer with great potential as a coating due to its low cost, high availability, and technological and functional properties. Among them, gelatin can be used as a carrier of bioactive compounds such as antioxidants, which can retard oxidation processes and thus extend the shelf-life of highly-perishable products. This study evaluated the effect of gelatin coating enriched with antioxidant tomato by-products hydrolysate (TBPH) on the quality of pork meat during cold storage. Results showed that TBPH obtained from Alcalase hydrolysis presented antioxidant activity with good stability against cooking. Additionally, chromatographic and mass spectrometry techniques, as well as in silico analysis, were used for the peptidomic characterisation of TBPH. The application of enriched gelatin coating on meat led to some physicochemical changes including increased weight loss and colour differences; however, the pH and water activity, which control meat spoilage, were maintained during storage. Moreover, coating prevented lipid oxidation of meat, and enriched-coated meat presented high antioxidant activity after cooking. These results suggest the positive role of gelatin coating enriched with TBPH in extending the shelf-life of meat during storage.Colicins are specific and potent toxins produced by Enterobacteriaceae that result in the rapid elimination of sensitive cells. Colicin production is commonly found throughout microbial populations, suggesting its potential importance for bacterial survival in complex microbial environments. Nonetheless, as colicin biology has been predominately studied using synthetic models, it remains unclear how colicin production contributes to survival and fitness of a colicin-producing commensal strain in a natural environment. To address this gap, we took advantage of MP1, an E. coli strain that harbors a colicinogenic plasmid and is a natural colonizer of the murine gut. Using this model, we validated that MP1 is competent for colicin production and then directly interrogated the importance of colicin production and immunity for MP1 survival in the murine gut. We showed that colicin production is dispensable for sustained colonization in the unperturbed gut. A strain lacking colicin production or immunity shows minimal fitness defects and can resist displacement by colicin producers.

Introduction Statistics on death are the basis of a country's health, safety, and welfare policies. Emergency physicians issue a postmortem examination certificate (PEC) for death outside the hospital as well as a death certificate (DC) for death in the hospital. This study investigated the actual conditions and criteria for writing a DC and PEC, writing environment, and doctor's experience. Material and methods The physicians' DC and PEC writing experience and demographic data were analyzed. https://www.selleckchem.com/products/loxo-195.html The questions focused on CPR, patient's medical certificate, time and place of death, difficulty in writing the PEC and DC, and education in certificate writing. Results 229 emergency physicians were included. Physicians' opinions differed for CPR patients in terms of time of death, location, and whether or not to issue DC/PEC. The causes of death were also different. Further, 76.9% of the doctors did not have enough time to write a medical certificate and about 45% of them wrote it within 30 min; 76% had DC-related complaints, and 7.0% faced legal problems due to the DC; 93.3% of the emergency physicians stated that a coroner system is needed in South Korea. Conclusion Emergency physicians are responsible for writing DCs and PECs. The standards vary from physician to physician at the time of writing. Writing DCs and PECs is also burdensome. In South Korea, it is necessary to separate the DC and PEC, to develop national data management networks, and to introduce a postmortem examination system.Estimates by the World Health Organization indicate that 1 in 3 women-more than one billion people worldwide-have experienced some form of Gender-Based Violence (GBV). Violence Against Women (VAW) is a prominent subset of GBV, defined by the United Nations as any act "that results in, or is likely to result in, physical, sexual, or mental harm or suffering to women, including threats of such acts, coercion or arbitrary deprivation of liberty, whether occurring in public or in private life." VAW can include verbal harassment, physical abuse, sexual abuse, honor killing, and femicide and can occur at the hands of individuals, institutions, or states. Whereas numerous studies have documented the multiple forms of physical, sexual, and psychological violence experienced by women, a thorough characterization of the abuses experienced by asylum-seeking women in the United States has not yet been undertaken. Our analysis of the affidavits for 85 cisgender, female asylum seekers who applied for forensic medical evaluations through a student-run asylum clinic, reveals a life-long pattern of multiple types of VAW inflicted by multiple perpetrators. These findings have implications for the focus of the medico-legal documentation submitted in support of female asylum seekers as well as for the design of comprehensive healthcare services for women and girls who are granted relief.The body of a 53-year-old man was found in a burning car. The ignition key was in start position and the accelerator pedal was held down by his right foot. Autopsy revealed a gunshot entrance wound in the hard palate, a bullet track through the anterior cranial fossa and a projectile lodged in the left frontal lobe. The brain stem was free of lesions and any signs of secondary brain injury, such as brain oedema and intracranial haemorrhage, were not significant. Soot deposits and thermal injury to the mucosa were observed in the airways below the glottis and carboxyhaemoglobin (COHb) saturation was 40%. A single bullet case and a handgun were recovered next to the driver's seat. Fire investigators identified the motor as the beginning of the burning therefore, the conclusion was that the car had caught fire due to overheating of the engine. Differential diagnosis between complex and complicated suicide was essential. The cause of death was identified as carbon monoxide intoxication, and the injuries to the brain were not felt to be immediately fatal. The case has been classified as a complicated suicide. There are no other published cases of a complicated suicide involving exposure to fire or the use of firearms.Conversion therapy is a set of practices that aim to change or alter an individual's sexual orientation or gender identity. It is practiced in every region of the world by health professionals, religious practitioners, and community or family members often by or with the support of the state. Conversion therapy is performed despite evidence that it is ineffective and likely to cause individuals significant or severe physical and mental pain and suffering with long-term harmful effects. The purpose of this medico-legal statement is to provide legal experts, adjudicators, health care professionals, and policy makers, among others, with an understanding of 1) the lack of medical and scientific validity of conversion therapy; 2) the likely physical and psychological consequences of undergoing conversion therapy; and 3) whether, based on these effects, conversion therapy constitutes cruel, inhuman, or degrading treatment or torture when individuals are subjected to it forcibly or without their consent. This medico-legal statement also addresses the responsibility of states in regulating the practice, the ethical implications of offering or performing it, and the role that health professionals and medical and mental health organisations should play with regards to it.Purpose Familiarization is necessary for an accurate strength assessment as it reduces confounding factors such as learning and training effects. However, the number of contractions required for familiarization and whether cross-limb transfer during familiarization could affect bilateral assessment are unknown. This study aimed at identifying the number of maximum contractions required for isokinetic knee extension and flexion familiarization in both dominant (D) and non-dominant limb (ND). Methods Twenty-eight right-limb dominant males (age 22.64 ± 2.60 years, BMI 23.82 ± 2.85 kg/m2) performed a total of 6 sets (each consisted of 5 continuous maximum contractions) at 60o/s for each limb. Results The number of sets required for familiarization is determined when the average peak torque achieved stabilization from the series of contractions of each limb. For knee extension, 3 sets (15 contractions) were required for familiarization, whereas 2 sets (10 contractions) for knee flexion in both limbs. Interestingly, for knee extension in ND, the number of sets required for familiarization was reduced to 2 following contralateral contractions in D, however, for knee extension in D, there was no difference in the number of sets required for familiarization following contralateral contractions in ND.

Furthermore, the GOx immobilization and enzyme activity in MC-COOH increased 140.72% and 252.74%, leading to the enhanced electroactive GOx surface coverage of Nafion/GOx/MC-COOH electrode (22.92% higher, 1.29 × 10-8 mol cm-2) than the control electrode. Results showed that carboxyl functionalization could increase the amount and activity of immobilized GOx, thereby improving the electrode properties.Background This study aimed at assessing socioeconomic inequalities in the increment of dental caries and growth among preschool Chinese children, and to assess the best predictor of socioeconomic inequality for each of these conditions. Methods This is a longitudinal population-based study. The sample data included preschool children living in three cities of the Liaoning Province, China. At baseline, 15 kindergartens with 1111 participants were included and dropped to 772 with a response rate of 70% at follow-up. Mean ages at baseline and follow-up were 50.82 and 60.55 months, respectively. Median follow-up time was 10.12 months. Data were collected through structured questionnaire, oral examination and anthropometric measurement. https://www.selleckchem.com/ The questionnaire collected information on sex, age, family income, mother's education and children's dietary habits. The numbers of decayed, missing and filled teeth (DMFT) was used to indicate dental caries. Weight- and height-for-age z-scores were calculated using the WHO Growth Standard. Multilevel analysis was used to assess the association between baseline socioeconomic position and each of dental caries and child's growth. Results Mother's education was negatively associated with increments of DMFT. Family income was not significantly associated with DMFT in the fully adjusted model. The association persisted after accounting for other socioeconomic and dietary factors. Higher income was positively related to an increase in the weight-for-age z-score. The relationship between income and changes in the height-for-age z-score was positive and significant in the second highest income group. Conclusions Mother's education appeared to be the strongest predictor of increments of dental caries. Only income was significantly associated with an increase in children's weight and height.Resveratrol is a naturally occurring polyphenol compound which has been shown to possess antioxidant and anti-inflammatory properties. However, its pharmaceutical applications are limited by its poor water solubility. In this study, we used electrospinning technology to synthesize nanofibers of polyvinylpyrrolidone (PVP) and hydroxypropyl-β-cyclodextrin (HPBCD) loaded with resveratrol. We used X-ray diffractometry to analyze crystalline structure, Fourier transform infrared spectroscopy to determine intermolecular hydrogen bonding, antioxidant assays to measure antioxidant activity, and Franz diffusion cells to evaluate skin penetration. Our results showed that the aqueous solubility of resveratrol nanofibers was greatly improved (by more than 20,000-fold) compared to the pure compound. Analysis of physicochemical properties demonstrated that following nanofiber formation, resveratrol was converted from a crystalline to amorphous structure, and resveratrol formed new intermolecular bonds with PVP and HPBCD. Moreover, resveratrol nanofibers showed good antioxidant activity. In addition, the skin penetration ability of resveratrol in the nanofiber formulation was greater than that of pure resveratrol. Furthermore, resveratrol nanofibers suppressed particulate matter (PM)-induced expression of inflammatory proteins (COX-2 and MMP-9) in HaCaT keratinocytes. Therefore, resveratrol-loaded nanofibers can effectively improve the solubility and physicochemical properties of resveratrol, and may have potential applications as an antioxidant and anti-inflammatory formulation for topical skin application.In this review, we retraced the '40-year evolution' of molecular docking algorithms. Over the course of the years, their development allowed to progress from the so-called 'rigid-docking' searching methods to the more sophisticated 'semi-flexible' and 'flexible docking' algorithms. Together with the advancement of computing architecture and power, molecular docking's applications also exponentially increased, from a single-ligand binding calculation to large screening and polypharmacology profiles. Recently targeting nucleic acids with small molecules has emerged as a valuable therapeutic strategy especially for cancer treatment, along with bacterial and viral infections. For example, therapeutic intervention at the mRNA level allows to overcome the problematic of undruggable proteins without modifying the genome. Despite the promising therapeutic potential of nucleic acids, molecular docking programs have been optimized mostly for proteins. Here, we have analyzed literature data on nucleic acid to benchmark some of the widely used docking programs. Finally, the comparison between proteins and nucleic acid targets docking highlighted similarity and differences, which are intrinsically related to their chemical and structural nature.Significant depots of brown adipose tissue (BAT) have been identified in many adult humans through positron emission tomography (PET), with the amount of BAT being inversely correlated with obesity. As dietary activation of BAT has implications for whole body glucose metabolism, leucine was used in the present study to determine its ability to promote BAT activation resulting in increased glucose uptake. In order to assess this, 2-deoxy-2-(fluorine-18)fluoro-d-glucose (18F-FDG) uptake was measured in C57BL/6 mice using microPET after treatment with leucine, glucose, or both in interscapular BAT (IBAT). Pretreatment with propranolol (PRP) was used to determine the role of β-adrenergic activation in glucose and leucine-mediated 18F-FDG uptake. Analysis of maximum standardized uptake values (SUVMAX) determined that glucose administration increased 18F-FDG uptake in IBAT by 25.3%. While leucine did not promote 18F-FDG uptake alone, it did potentiate glucose-mediated 18F-FDG uptake, increasing 18F-FDG uptake in IBAT by 22.

The results showed injury of aortic endothelium, along with reductions of the concentration of nitric oxide and generation of VEGF in diabetic rats. However, β-hydroxybutyrate treatment attenuated diabetic injury of the endothelium and up-regulated the generation of VEGF. Furthermore, β-hydroxybutyrate treatment caused marked total protein β-hydroxybutyrylation and significant elevation of H3K9bhb content in the aorta of diabetic rats. The ability of β-hydroxybutyrate to protect against diabetic injury of the aortic endothelium was greatest for its intermediate concentration. In conclusion, moderately elevated β-hydroxybutyrate could antagonize aortic endothelial injury, potentially by causing H3K9bhb to promote generation of VEGF in diabetic rats.The jugular ganglion (JG) contains sensory neurons of the vagus nerve which innervate somatic and visceral structures in cranial and cervical regions. In this study, the number of sensory neurons in the human JG was investigated. And, the morphology of sensory neurons in the human JG and nodose ganglion (NG) was compared. The estimated number of JG neurons was 2721.8-9301.1 (average number of sensory neurons ± S.D. = 7975.1 ± 3312.8). There was no significant difference in sizes of the neuronal cell body and nucleus within the JG (cell body, 1128.8 ± 99.7 μ m2; nucleus, 127.7 ± 20.8 μ m2) and NG (cell body, 963.8 ± 225.7 μ m2; nucleus, 123.2 ± 32.3 μ m2). These findings indicate that most of sensory neurons show the similar morphology in the JG and NG. Our immunohistochemical method also demonstrated the distribution of ion channels, neurotransmitter agents and calcium-binding proteins in the human JG. Numerous JG neurons were immunoreactive for transient receptor potential cation channel subfamily V member 1he external auditory canal. It is likely that sensory neurons in the human JG can transduce nociceptive and mechanoreceptive information from the external auditory canal. Theses neurons may be also associated with neurogenic inflammation in the external auditory canal and ear-cough reflex through the vagus nerve.Objective Considering the association of macrophage migration inhibitory factor with development of prostate diseases, this study aims to explore the effect and mechanism of macrophages (MAs) in inflammation and proliferation of benign prostate hyperplasia (BPH) cells. Methods Totally 85 prostate tissues (75 from BPH patients and 10 from brain death patients) were collected for determination of biomarkers of T lymphocyte (CD4 and CD8), B lymphocyte (CD20) and MAs (CD68), as well as androgen receptor (AR) and CD40/CD40L. MAs stimulated by phorbol myristate acetate (PMA) were cultured with BPH cells (BPH-1), followed by AR inhibitor or anti-CD40 L antibody treatment. Proliferation and cell apoptosis were observed by MTT assay, colony formation assay and flow cytometer. Expressions of apoptotic related proteins and MAPK signaling pathway-related proteins were determined by qRT-PCR and Western blot. Results BPH tissues had increased expressions of AR, CD40 and CD40 L, as well as elevated expressions of inflammation biomarkers (CD4, CD8, CD20 and CD68) in comparison to normal prostate tissues. MAs could increase the expressions of lymphocytes and inflammation biomarkers, in addition to promoting cell proliferation and inhibiting cell apoptosis. Cell proliferation and inflammation reaction could be attenuated by anti-CD40 L antibody and AR inhibitor in a concentration dependent manner through inhibiting the phosphorylation of JNK, ERK1/2 and p38. Conclusion MAs regulate AR and CD40/CD40L expression to promote the inflammation and proliferation as well as inhibiting apoptosis of BPH-1 cells through activation of the MAPK signaling pathway. https://www.selleckchem.com/products/mmaf.html This conclusion may provide a therapeutic strategy for BPH patients.The developmental changes of Sertoli cells were examined and described in the freshwater pearl mussel Margaritifera laevis using light and transmission electron microscopy. Sertoli cells, which are located on the basal lamina of acini in the testis, include a large number of glycogen granules, electron-dense globules, lipid droplets, and sperm morulae. Electron-dense globules are the vacuoles into which the electron-dense material is condensed. In aging Sertoli cells, the content of the globules leaks out to the extracellular area. Large lipid droplets are formed by the deposition of smaller lipid droplets into a vacuole. After the disruption of the Sertoli cell, the lipid droplets are discharged to the extracellular area and fuse with to form a larger mass. The spermatogonia which were engulfed by the Sertoli cells begin to condense their chromatin and transform themselves into sperm morulae. The constituent cells of the sperm morulae proliferate and finally differentiate into the spermatozoa. After the disruption of the Sertoli cell, the spermatozoa produced from the sperm morulae are released into the acinus lumen. Numerous matured spermatozoa in the acini gather around the large lipid droplet, to form the sperm sphere. The completed sperm spheres are subsequently released through the exhalant siphon into the stream.Oral-Facial-Digital type I (OFD1) is a rare inherited form of renal cystic disease associated with ciliary dysfunction. This disorder is due to mutations in the OFD1 gene that encodes a protein localized to centrosomes and basal bodies in different cell types. Immunofluorescence analysis demonstrated that OFD1 displays a dynamic distribution during cell cycle. High-content microscopy analysis of Ofd1-depleted fibroblasts revealed impaired cell cycle progression. Immunofluorescence analysis and cell proliferation assays also indicated the presence of a variety of defects such as centrosome accumulation, nuclear abnormalities and aneuploidy. In addition, Ofd1-depleted cells displayed an abnormal microtubule network that may underlie these defects. All together our results suggest that OFD1 contributes to the function of the microtubule organizing center (MTOC) in the cell, controlling cell cycle progression both in vitro and in vivo.Deltex-3-like (DTX3L), an E3 ligase, which is also known as B-lymphoma and BAL-associated protein (BBAP), is a member of the Deltex (DTX) family and was originally identified as a binding partner of diphtheria-toxin-like ADP-ribosyltransferase-9 (ARTD9). The present study found that DTX3L and ARTD9 were upregulated in synovial tissues obtained from rheumatoid arthritis (RA) patients compared with those from the controls. Healthy synovial tissues were obtained by arthroscopic biopsy from patients with meniscus injury (n = 10 samples) without a history of RA in the Orthopedic Department of the Affiliated Hospital of Nantong University. FLSs were isolated from RA patients who underwent total knee arthroplasty. We performed dual immunofluorescence staining on DTX3L and ARTD9, and these data strongly demonstrated that DTX3L and ARTD9 were colocalized with fibroblast-like synoviocytes (FLSs) in patients with RA. Furthermore, Western blot assays were performed to confirm that the expression levels of DTX3L and ARTD9 in the FLSs increased in a time-dependent manner and peaked at 24 h after TNF-α stimulation.

Collectively, the dynamic Ras-Raf assembly promotes Raf activation not by allostery; instead, Ras activates Raf by shifting its ensemble toward kinase domain-accessible states through enhanced affinity at the membrane. © 2020 The Authors.Pathogenic mutation in BRCA1 gene is one of the most penetrant genetic predispositions towards cancer. Identification of the mutation provides important aspect in prevention and treatment of the mutation-caused cancer. Of the large quantity of genetic variants identified in human BRCA1, substantial portion is classified as Variant of Uncertain Significance (VUS) or unclassified variants due to the lack of functional evidence. In this study, we focused on the VUS and unclassified variants in BRCT repeat located at BRCA1 C-terminal. Utilizing the well-determined structure of BRCT repeats, we measured the influence of the variants on the structural conformations of BRCT repeats by using molecular dynamics simulation (MDS) consisting of RMSD (Root-mean-square-deviation), RMSF (Root-mean-square-fluctuations), Rg (Radius of gyration), SASA (Solvent accessible surface area), NH bond (hydrogen bond) and Covariance analysis. Using this approach, we analyzed 131 variants consisting of 89 VUS (Variant of Uncertain Significance) and 42 unclassified variants (unclassifiable by current methods) within BRCT repeats and were able to differentiate them into 78 Deleterious and 53 Tolerated variants. Comparing the results made by the saturation genome editing assay, multiple experimental assays, and BRCA1 reference databases shows that our approach provides high specificity, sensitivity and robust. Our study opens an avenue to classify VUS and unclassified variants in many cancer predisposition genes with known protein structure. © 2020 The Authors.The calcium-activated chloride channel, also known as TMEM16A, shows both calcium and membrane potential dependent activation. The channel is expressed broadly and contributes to a variety of physiological processes, and it is expected to be a target for the treatment of diseases such as hypertension, pain, cystic fibrosis and lung cancer. A thorough understanding of the structural characteristics of TMEM16A is important to reveal its physiological and pathological roles. Recent studies have released several Cryo-EM structures of the channel, revealed the structural basis and mechanism of the gating of the channel. This review focused on the understandings of the structural basis and molecular mechanism of the gating and permeation of TMEM16A channel, which will provide important basis for the development of drugs targeting TMEM16A. © 2020 The Authors.

There is clear evidence for regulation of SERCA activity by PLB, whose activity is modulated by phosphorylation of its N-terminal domain (residues 1-25), but there is less clear evidence for the role of this domain in PLB's functional divergence. It is widely accepted that only sarcolipin (SLN), a protein that shares substantial homology with PLB, uncouples SERCA Ca2+ transport from ATP hydrolysis by inducing a structural change of its energy-transduction domain; yet, experimental evidence shows that the transmembrane domain of PLB (residues 26-52, PLB26-52) partially uncouples SERCA in vitro. These apparently conflicting mechanisms suggest that PLB's uncoupling activity is encoded in its transmembrane domain, and that it is controlled by the N-terminal phosphorylation domain. To test this hypothesis, we performed molecular dynamics simulations (MDS) of the binary complex between PLB26-52 and SERCA. Comparison between PLB26-52 and wild-type PLB (PLBWT) showed no significant changes in the stability and orientation of the transmembrane helix, indicating that PLB26-52 forms a native-like complex with SERCA. MDS showed that PLB26-52 produces key intermolecular contacts and structural changes required for inhibition, in agreement with studies showing that PLB26-52 inhibits SERCA. However, deletion of the N-terminal phosphorylation domain facilitates an order-to-disorder shift in the energy-transduction domain associated with uncoupling of SERCA, albeit weaker than that induced by SLN. This mechanistic evidence reveals that the N-terminal phosphorylation domain of PLB is a primary contributor to the functional divergence among homologous SERCA regulators. © 2020 The Authors.The density regulated protein (DENR) forms a stable heterodimer with malignant T-cell-amplified sequence 1 (MCT-1). https://www.selleckchem.com/products/H-89-dihydrochloride.html DENR-MCT-1 heterodimer then participates in regulation of non-canonical translation initiation and ribosomal recycling. The N-terminal domain of DENR interacts with MCT-1 and carries a classical tetrahedral zinc ion-binding site, which is crucial for the dimerization. DENR-MCT-1 binds the small (40S) ribosomal subunit through interactions between MCT-1 and helix h24 of the 18S rRNA, and through interactions between the C-terminal domain of DENR and helix h44 of the 18S rRNA. This later interaction occurs in the vicinity of the P site that is also the binding site for canonical translation initiation factor eIF1, which plays the key role in initiation codon selection and scanning. Sequence homology modeling and a low-resolution crystal structure of the DENR-MCT-1 complex with the human 40S subunit suggests that the C-terminal domain of DENR and eIF1 adopt a similar fold. Here we present the crystal structure of the C-terminal domain of DENR determined at 1.74 Å resolution, which confirms its resemblance to eIF1 and advances our understanding of the mechanism by which DENR-MCT-1 regulates non-canonical translation initiation and ribosomal recycling. © 2020 The Authors.Hepatocellular carcinoma (HCC) is an essentially incurable inflammation-related cancer. We have previously shown by network analysis of proteomic data that the flavonoids epigallocatechin gallate (EGCG) and fisetin (FIS) efficiently downregulated pro-tumor cytokines released by HCC through inhibition of Akt/mTOR/RPS6 phospho-signaling. However, their mode of action at the global transcriptome level remains unclear. Herein, we endeavor to compare gene expression alterations mediated by these compounds through a comprehensive transcriptome analysis based on RNA-seq in HEP3B, a responsive HCC cell line, upon perturbation with a mixture of prototypical stimuli mimicking conditions of tumor microenvironment or under constitutive state. Analysis of RNA-seq data revealed extended changes on HEP3B transcriptome imposed by test nutraceuticals. Under stimulated conditions, EGCG and FIS significantly modified, compared to the corresponding control, the expression of 922 and 973 genes, respectively, the large majority of which (695 genes), was affected by both compounds.

BACKGROUND Children with and without speech sound disorders (SSDs) are exposed to different patterns of infant feeding (breast/bottle-feeding) and may or may not engage in non-nutritive sucking (NNS) (pacifier/digit-sucking). Sucking and speech use similar oral musculature and structures, therefore it is possible that early sucking patterns may impact early speech sound development. The objective of this review is to synthesise the current evidence on the influence of feeding and NNS on the speech sound development of healthy full-term children. SUMMARY Electronic databases (PubMed, NHS CRD, EMBASE, MEDLINE) were searched using terms specific to feeding, NNS and speech sound development. All methodologies were considered. Studies were assessed for inclusion and quality by 2 reviewers. Of 1,031 initial results, 751 records were screened, and 5 primary studies were assessed for eligibility, 4 of which were included in the review. Evidence from the available literature on the relationship between feeding, NNS an.

Here, we investigated how the surface defects and conduction-band (CB) offsets between core and shell materials affect the PET from CuInS2 quantum dots (QDs) by means of time-resolved femtosecond transient absorption and nanosecond photoluminescence spectroscopy. The transfer of 1S excited electrons from CuInS2 QDs to TiO2 films is demonstrated and we find that the surface-electron trapping can significantly reduce the efficiency of the PET. Though the electron trapping can be suppressed after ZnS surface passivation, the PET decreases significantly to a low efficiency of ∼33% from the type I CuInS2/ZnS core/shell QDs because of their low electron density at the surface of the QDs. The surface-electron density is increased with the strategy of wavefunction engineering by reducing the CB offset, which allows us to achieve a quasi-type II carrier confinement in CuInS2/CdS core/shell QDs. The PET efficiency appears to be as high as ∼95% from the CuInS2/CdS core/shell QDs, which is ascribed to synergistic effects of the surface passivation and enhanced delocalization of the electron wavefunction from the CuInS2 core to the CdS shell. Finally, we demonstrate that these new mechanistic understandings of the PET processes are crucial to improving the efficiency of CuInS2 QDSSCs.An ultrathin near-perfect MoSe2 absorber working in the visible regime is demonstrated theoretically and experimentally, and it consists of a MoSe2/Au bi-layer film. The polymer-assisted deposition method is used to synthesize MoSe2 films, which can reduce the roughness and thus improve the film absorption. https://www.selleckchem.com/products/AC-220.html Simulation results show that the absorption of the absorber with 22 nm MoSe2 reaches to larger than 90% between 628.5 nm and 718 nm with a peak value up to 99.5% at 686 nm. Moreover, the measured absorption also shows near-perfect absorption of this simple absorber. Finally, an ultrathin photodetector is fabricated based on this perfect absorber and shows on/off reproducibility and remarkable photocurrent, which is three orders of magnitude higher than the dark current.The first step in every systematic approach to investigating population exposure to radon on a national level is to perform a comprehensive indoor radon survey. Based on the general knowledge of the radon levels in Serbia and corresponding doses, the results obtained from a national indoor radon survey would allow policy-makers to decide if it is necessary to establish a national radon programme. For this reason, Serbia initiated work on a national radon action plan (RAP) in 2014 when it was decided to carry out the first national indoor radon survey. The responsibility for establishing the RAP in Serbia is that of the national regulatory body in the field of radiation protection - the Serbian Radiation and Nuclear Safety and Security Directorate (SRBATOM), formerly known as the Serbian Radiation Protection and Nuclear Safety Agency (SRPNA). The first national indoor radon survey was supported by the International Atomic Energy Agency (IAEA) through a Technical Cooperation Programme. Thanks to the IAEA, we received 6,000 passive radon devices based on track-etched detectors. In addition, in order to ensure technical support for the project, SRBATOM formed a task force made up of expert radon representatives from national research institutions. This paper presents a thorough description of the sampling design of the first Serbian indoor radon survey. It also presents the results of the national indoor radon survey, including descriptive statistics and testing of the distribution of the obtained results for log-normality. Based on GPS coordinates, indoor radon data were projected onto a map of 10x10 km grid cells. Two values were calculated for each cell to create two distinct maps. One map shows the arithmetic mean value of indoor radon concentration per grid cell, and the other map shows the number of radon detectors per grid cell used for the calculation of mean values. © 2020 Society for Radiological Protection.

We propose a solvated potential model that approximates the potential energy of a solvated protein by projecting the solvent information into the protein structure. Using the model, we derive three properties of the solvent. First, the influence of the solvent on protein structure and dynamics, mostly by the bulk solvent, decays drastically (near-exponentially) as the distances of the solvent from the protein increases. This decay pattern can be used to determine the economical size of solvent boxes in molecular dynamics simulations. Second, the hydration shell regulates the protein dynamics by effecting extra interactions within the protein structure. Lastly, the lowest frequency modes are determined mostly by protein structures. © 2020 IOP Publishing Ltd.
