Function associated with laminin as well as bovine collagen organizations inside human being spermatogenesis * Insights via reports within rats along with scRNA-Seq transcriptome profiling.
In addition to confirming the 7 cleavage sites, 9 new sites (R122, R137, R138, K150, K170, R172, R180, K181, K189) in synthesized peptides were found to be cleaved by plasmin with mass spectrometry. These cleavage sites were located in the finger and the thumb, particularly the GRIP domain of human ENaC 3D model composed of two proteolytic centres for plasmin. Novel uncleaved sites beyond the GRIP domain in both α and γ subunits were identified to interrupt the plasmin cleavage-induced conformational change in ENaC channel complexes. Additionally, plasmin could regulate ENaC activity via the G protein signal. CONCLUSION AND IMPLICATIONS We demonstrate that plasmin could cleave ENaC to benefit the blood-gas exchange by resolving oedema fluid as a potent fibrinolytic therapy for oedematous pulmonary diseases.

Variceal bleeding commonly occurs in children with chronic liver disease or portal vein obstruction. Therefore, prevention is important. Primary prophylaxis of variceal bleeding in adults is the established standard of care because of the results of numerous randomised clinical trials demonstrating the efficacy of non-selective beta-blockers or endoscopic variceal ligation in decreasing the incidence of variceal bleeding. In children, band ligation, beta-blockers, and sclerotherapy have been proposed as alternatives for primary prophylaxis of oesophageal variceal bleeding. However, it is unknown whether those treatments are of benefit or harm when used for primary prophylaxis in children. OBJECTIVES To assess the benefits and harms of sclerotherapy compared with sham or no intervention for primary propeed to be interpreted with caution. Larger randomised clinical trials, following the SPIRIT and CONSORT statements, assessing the benefits and harms of sclerotherapy compared with sham or no intervention for primary prophylaxis of oesophageal variceal bleeding in children with chronic liver disease or portal vein thrombosis are needed. The trials should include important clinical outcomes such as death, failure to control bleeding, and adverse events. Copyright © 2020 The Cochrane Collaboration.

Two previous studies that used the 50 mg dose in HHD patients (3 patients total) had failed to show any positive response. This article is protected by copyright.

Real-life evidence has shown that the switch from infliximab originator to CT-P13 did not impair overall clinical efficacy and safety in patients with Crohn's disease, ulcerative colitis, spondyloarthritis, rheumatoid arthritis, psoriatic arthritis and chronic plaque psoriasis.

Hepatocyte growth factor (HGF) protects cardiomyocytes from injury, but its administration is hampered by low biodistribution. In this study we investigated whether the activation of the HGF receptor - encoded by the Met gene - by an agonist monoclonal antibody (mAb) protects from doxorubicin-induced cardiotoxicity. EXPERIMENTAL APPROACH MAb (5 mg/kg) was injected in vivo into C57BL/6J mice prior to doxorubicin (three doses of 7 mg/kg). The cardiac functions were evaluated through magnetic resonance imaging (MRI) after treatment termination. Heart histological staining and mRNA levels of genes associated with heart failure (Acta1, Nppa), inflammation (IL-6) and fibrosis (Ctgf, Col1a2, Timp1, and Mmp9) were assessed. MAb (100 nM) was administered in vitro to H9c2 cardiomyoblasts before addition of doxorubicin (25 μM). DDR and apoptosis markers were evaluated by quantitative western blotting, flow cytometry and immunofluorescence. Stattic was used for pharmacological inactivation of signal transducer and activation of transcription 3 (Stat3). KEY RESULTS In vivo, administration of mAb alleviated doxorubicin-induced cardiac dysfunction and fibrosis. In vitro, mAb mimicked the response to HGF by (i) inhibiting histone H2AX phosphorylation at S139, (ii) quenching the expression of the DNA repair enzyme poly (ADP-ribose) polymerase 1, and (iii) reducing the proteolytic activation of caspase 3. The Met-driven cardioprotection involved, at least in vitro, the phosphorylation of Stat3. CONCLUSION AND IMPLICATIONS This paper shows that Met agonist mAb provides a new tool for cardioprotection against anthracycline cardiotoxicity. This article is protected by copyright.

Several sex differences in GABA-mediated responses are gonadal hormone-dependent; however, few studies have dealt with sex differences detected before the critical period of brain masculinisation. In this study, we assessed GABAA receptor functionality in sexually segregated neurons before brain hormonal masculinisation. EXPERIMENTAL APPROACH Ventromedial hypothalamic neurons were obtained from embryonic day 16 rat brains and grown in vitro for 2 days. Calcium imaging and electrophysiology recordings were carried out to assess GABAA receptor functional parameters. KEY RESULTS GABAA receptor activation elicited calcium entry in immature hypothalamic neurons mainly through L-type voltage-dependent calcium channels. Nifedipine blocked calcium entry more efficiently in male than in female neurons. There were more male than female neurons responding to GABA, and they needed more time to return to resting levels. Pharmacological characterisation revealed that propofol enhanced GABAA -mediated currents and blunted GABA-mediated calcium entry more efficiently in female neurons than in males. Testosterone treatment did not erase such sex differences. These data suggest sex differences in the expression of GABAA receptor subtypes. CONCLUSION AND IMPLICATIONS GABA-mediated responses are sexually dimorphic even in the absence of gonadal hormone influence, suggesting genetically biased differences. These results highlight the importance of GABAA receptors in hypothalamic neurons even before hormonal masculinisation of the brain. This article is protected by copyright.

The aim of the present study was to investigate the melanoma specific survival (MSS) as well as conditional MSS (CMSS) in patients with thin CMM in Sweden. METHOD Clinical and histologic parameters from the Swedish Melanoma Registry were obtained for patients diagnosed with thin CMM between 1990-2017. Patients were followed until the end of 2017. MSS as well as CMSS for different thickness groups were calculated using Kaplan-Meier method and Cox regression analyses were used to calculate for survival differences between thickness groups. RESULTS 31 670 patients were included for final analyses. The overall 10- and 20-year MSS for thin CMMs was 97% (95% CI 97-97) and 95% (95% CI 95-96) respectively. From 0·7 mm and above, MSS decreased significantly with increasing thickness level. All thickness groups had an increased survival over time. The lowest CMSS was confirmed for men with 1·0 mm in thickness but their 10-year CMSS steadily increased over time. Women had overall better MSS as well as CMSS than men. However, the relation between MSS and CMSS was similar for both sexes. CONCLUSION Long-term MSS was confirmed excellent for patients with thin CMMs in Sweden. Although we could show a decreased MSS for patients with 0·7 mm and above, the long-term survival and in addition a very favourable CMSS for those patients, do not support more extended follow-up programs than current recommendations in Sweden.

An up-to-date analysis of international MM mortality trends is required for assessing burden of disease, and may support assessment of the effectiveness of new diagnostic, therapeutic and preventative strategies. OBJECTIVES To report MM mortality trends between 1985 and 2015 using the World Health Organization (WHO) Mortality Database. METHODS We used country-level MM mortality data from the WHO Mortality Database for all countries with high usability death registration data. Mortality trends were described using Joinpoint regression modelling. RESULTS 31 countries met inclusion criteria. All countries demonstrated increased age-standardised death rates (ASDRs) in males over the observation period except the Czech Republic. More countries exhibited decreased or stable MM mortality in females. Median mortality for 2013-2015 was 2.57 deaths per 100 000 for males and 1.55 per 100 000 for females. Australia and Norway had the highest ASDRs for males (5.72 per 100 000 and 4.55 per 100 000, respectively). Norway and Slovenia had the highest ASDRs for females (3.02 per 100 000 and 2.58 per 100 000, respectively). MM mortality was greater for males than females in all countries, with sex disparity increasing across the period. Disparity in mortality between older and younger cohorts in several countries was also found. CONCLUSIONS Overall increase in MM mortality over the past 30 years was observed. However, there was notable variation in mortality trends between countries, as well as between males and females, and between different age groups. This article is protected by copyright.

Sixty-two individuals were sampled; muscle and liver were isolated and analyzed by atomic absorption spectrophotometry. The mean Hg concentrations (wet weight) obtained for muscle (0.08 ± 0.10 μg g-1) and liver (0.09 ± 0.26 μg g-1) were below the allowed limits ( less then  1.0 μg g-1 Hg). The average Se concentration was 0.03 ± 0.01 μg g-1 in muscle and 0.13 ± 0.05 μg g-1 in liver. The Se/Hg molar ratio of muscle was 1.83; however, the selenium health benefit value (HBVSe) was of 0.08. We calculated that an adult man (70 kg), an adult woman (60 kg), and a child (16 kg) could consume 1595, 838, and 223 g/week of M. henlei muscle, respectively, without risks to health. In conclusion, the concentrations and molar ratio of Hg and Se in M. henlei muscle mean that consumption of this shark's meat does not represent neither a benefit nor a public health risk.
