Recent experience has shown that it is possible to use ML to discover new antiviral candidates from virtual screening and drug repurposing.Extracellular matrix (ECM) plays an important role in tissue repair, cell proliferation, and differentiation. Our previous study showed that collagen I and collagen V differently regulate the proliferation of rat pancreatic β cells (INS-1 cells) through opposite influences on the nuclear translocation of β-catenin. In this study, we investigated the β-catenin pathway in INS-1 cells on dishes coated with collagen I or V. check details We found that nuclear translocation of the transcription factor Yes-associated protein (YAP) was enhanced by collagen I and suppressed by collagen V, but had no effect on INS-1 cell proliferation. Morphologically, INS-1 cells on collagen V-coated dishes showed stronger cell-to-cell adhesion, while the cells on collagen I-coated dishes showed weaker cell-to-cell adhesion in comparison with the cells on non-coated dishes. E-cadherin played an inhibitory role in the proliferation of INS-1 cells cultured on collagen I or collagen V coated dishes via regulation of the nuclear translocation of β-catenin. Integrin β1 was enhanced with collagen I, while it was repressed with collagen V. The integrin β1 pathway positively regulated the cell proliferation. Inhibition of integrin β1 pathway restored the protein level of E-cadherin and inhibited the nuclear translocation of β-catenin in the cells on collagen I-coated dishes, but no effect was observed in the cells on collagen V-coated dishes. In conclusion, collagen I enhances the proliferation of INS-1 cells via the integrin β1 and E-cadherin/β-catenin signaling pathway. In INS-1 cells on collagen V-coated dishes, both integrin β1 and E-cadherin/β-catenin signal pathways are involved in the inhibition of proliferation.Y‑autosome translocations are relatively uncommon in humans, with t(Y;1) stated to be even rarer. On the contrary, pericentric inversion 9 is the most commonly seen inversion of chromosome . Although considered to have no significant effect on male fertility, the literature reporting on reproductive risks for both aberrations remains controversial. We report here, as far as we know, the first case of a unique combination of balanced reciprocal translocation t(Y;1) with pericentric inversion of chromosome 9 in a patient with nonobstructive azoospermia (NOA) and an otherwise normal phenotype. Our patient was a 37-year-old Caucasian male sent to our Department due to azoospermia reported by semen analysis. The cytogenetic analysis revealed a balanced reciprocal translocation including chromosomes Y and 1 in all observed metaphases 46, X,t(Y;1)(q12;q21) and a pericentric inversion of chromosome 9 inv(9)(p12q13). By performing metaphase FISH, the t(Y;1) translocation was confirmed. By means of multiplex-PCR, no Y-chromosome microdeletions were detected in the AZF regions. This report demonstrates a unique karyotype showing balanced reciprocal translocation t(Y;1)(q12;q21) with pericentric inversion 9 inv(9)(p12q13), in a patient with NOA, and highlights the importance of appropriate genetic counseling for patients with regard to the medical management of balanced chromosomal aberrations.Glutaminase is an important target that is often over expressed in neurodegenerative and lifestyle related diseases but few effective inhibitors of this enzyme have yet reached clinical trials. Ursolic acid (1), betulinic acid (2) and oleanolic acid (3), three pentacyclic triterpene acids, have been isolated from the leaves of Thymus vulgaris L. Enzyme inhibition experiments demonstrated their inhibitory effects against glutaminase activity. Compound 2 significantly inhibited the glutaminase activity with IC50 of 0.31 mM, stronger than the positive control 6-diazo-5-oxo-L-norleucine (DON) with IC50 of 0.57 mM. Compound 2 may serve as a potential lead compound for the prevention and treatment of neurodegenerative diseases and lifestyle related diseases by targeting glutaminase. This is the first report on glutaminase inhibitory activities of 1-3 isolated from T. vulgaris L.Self-inflicted injury, the most common form of intentional injury, disproportionately affects low-income countries, but is poorly described in this setting. This retrospective review of the 2008-2018 trauma registry at a referral hospital in Malawi included all victims of intentional injury ≥10 years. Self-inflicted injuries were compared to assaults. The primary outcome was in-hospital mortality. Common mechanisms of self-inflicted injuries were fall from height, poisoning, and penetrating injury. In-hospital mortality from self-inflicted injury was 8.8% vs. 1.9% for assault. Those who died from self-inflicted injury were more often older (median 34 vs. 26 years, p less then 0.001), male (91.9% vs. 67.8%, p less then 0.001), unemployed (32.8% vs. 6.4%, p less then 0.001), and most commonly died by hanging (60%). The odds of in-hospital mortality after self-inflicted injury was four times assault (OR 4.0 [95% CI 1.4-11.5], p = 0.01). The trauma registry proved useful for describing self-inflicted injury in this setting.Jasminum multiflorum Burm. f. (J. multiflorum) is an ornamental plant with traditional medicinal importance. This study aims to evaluate the activity of J. multiflorum isolated compounds against hepatocellular carcinoma cells infected with hepatitis C virus (HCV) in vitro. The in vitro anti-viral and anti-oncogenic-related activity were validated by anchorage-independent assay plus transwell migration/invasion and spreading assay. In addition to chromatographic isolation of the active metabolites. The flower extract demonstrated a significant antiviral potential through reducing active viral replication by more than 90%. Study results credit this to specific reduction of viral NS5A and cellular EphA2 protein levels. Molecular docking analysis proved the role of the isolated compounds especially multifloroside, jasfloroside A and jasfloroside B as possible anti HCV molecules.We sought to provide evidence for a combined effect of two attentional mechanisms during associative learning. Participants' eye movements were recorded as they predicted the outcomes following different pairs of cues. Across the trials of an initial stage, a relevant cue in each pair was consistently followed by one of two outcomes, while an irrelevant cue was equally followed by either of them. Thus, the relevant cue should have been associated with small relative prediction errors, compared to the irrelevant cue. In a later stage, each pair came to be followed by one outcome on a random half of the trials and by the other outcome on the remaining half, and thus there should have been a rise in the overall prediction error. Consistent with an attentional mechanism based on relative prediction error, an attentional advantage for the relevant cue was evident in the first stage. However, in accordance with a mechanism linked to overall prediction error, the attention paid to both types of cues increased at the beginning of the second stage.
