r patients' healthcare during the pandemic.<br />The results of the retrospective study indicated that clinical pharmacist can effectively reduce and prevent drug-related, life-related and COVID-19-related problems for COVID-19 patients, which is important for the disease recovery. This study also demonstrated that clinical pharmacist played a key role for patients' healthcare during the pandemic.Hepatitis E virus (HEV) infection is the most common cause of acute viral hepatitis worldwide. However, host-HEV interactions have yet to be fully understood. Zinc-finger antiviral protein (ZAP) is a novel interferon (IFN)-stimulated gene product that inhibits a variety of viruses in synergy with IFN-β. To evaluate the role of ZAP in HEV infection, its expressions in HEV-infected patients and in cell cultures were measured. We report a significant inhibition of ZAP expression in patients with HEV genotype four acute infection. The expression of ZAP in the HEV life cycle was monitored in cultures of HEV-infected cells. Results indicated that the ZAP level decreased significantly after HEV infection. ZAP over-expression inhibited HEV replication, whereas its knockdown by RNA interference significantly increased HEV RNA. These suggest that ZAP serves as an antiviral in HEV infection. Moreover, silencing ZAP decreased IFN regulatory factor 3 (IRF3) phosphorylation in HEV-infected cells treated with poly(IC), indicating that ZAP synergizes with IFN-β. In conclusion, ZAP is an important anti-HEV host factor and in synergy with IFN-β, inhibits HEV replication.Some studies have exposed an increase in liver cirrhosis in hepatitis E seropositive individuals living with human immunodeficiency virus. The interrelation between HEV seroprevalence and risk of liver disease in immune-competent individuals remains under- investigated. Using the National Health and Nutrition Examination Survey (NHANES) data containing &gt;30,000 subjects, we addressed if HEV exposure leads to subclinical effects that can influence liver health. We determined the association between HEV IgM and ALT and that of HEV IgG and Fib-4-a composite score reflecting potential liver fibrosis. These analyses were repeated in populations at risk for liver disease as well as among different races and ethnicities. The prevalence of HEV IgG was significantly associated with age as IgG positive individuals were, on average, 20 years older than IgG negative patients. We found a statistically significant increase in the likelihood of having a Fib-4 score &gt;1.45 (significant fibrosis) in those positive for HEV IgG (RR 1.03; 95% CI 1.01-1.05). However, due to the small effect, it is unlikely that this association has clinical significance. Moreover, the effect was not present in those with pre-existing liver disease. We found no association between ALT levels and the presence of HEV IgM or IgG. This is the first study examining subclinical effects of HEV infection in the United States. Our study found that in the general US population, predominantly asymptomatic HEV infections do not contribute to the overall burden of liver disease.<br />Elevated serum matrix metalloproteinase-8 (MMP-8) concentrations are associated with high risk of vascular disease, but the causality remains unclear. A two-sample Mendelian randomization (MR) study was performed to examine the causal effect of serum MMP-8 concentrations on the risk of ischaemic stroke, ischaemic stroke subtypes and coronary artery disease.<br />Ten independent single-nucleotide polymorphisms related to serum MMP-8 concentrations were identified as instrumental variables from a genome-wide association study of 6049 European subjects. Genetic association estimates for ischaemic stroke were obtained from the Multiancestry Genome-wide Association Study of Stroke consortium with 446,696 European individuals. The inverse-variance weighted method was applied to assess the causal associations of serum MMP-8 with ischaemic stroke and its subtypes in the main analysis.<br />No significant causal association was observed for MMP-8 levels with total ischaemic stroke, large artery stroke or cardioembolic str system requires further investigation.<br />Ultraviolet (UV) radiation is a key risk factor of environment to contribute photoaging and skin cancer through production of reactive oxygen species (ROS) and inflammatory responses. Here, we explored the effects of Astragaloside IV (AS-IV), an active component from Astragalus membranaceus, on UVB-induced oxidative injury and inflammatory response in human epidermal keratinocytes.<br />HaCaT keratinocytes were exposed to UVB irradiation, followed by AS-IV incubation. The cell viability, intracellular ROS level, oxidative stress, and apoptosis were determined. The regulatory effects of AS-IV on toll-like receptor 4 (TLR4) pathway in UVB-exposed HaCaT cells were also investigated.<br />AS-IV pretreatment (10, 25, 50, 100 and 150 μM) increased cell viability in UVB-exposed HaCaT cells. AS-IV (50 μM) significantly reduced intracellular ROS level and lipid oxidation product malondialdehyde (MDA) content, and increased a ROS-scavenging enzyme superoxide dismutase (SOD) in HaCaT cells with UVB irradiation. In addition, AS-IV pretreatment suppressed apoptosis, increased Bax protein, caspase-3 and 9, and decreased BCL-2 protein in contrast to HaCaT cells with UVB-irradiation. AS-IV suppressed proinflammatory cytokine production, inhibited TLR4 and its downstream signaling molecules NF-κB, iNOS and cyclooxygenase-2 (COX-2) protein expression. We also found that the effects of AS-IV on cell viability and TLR4 expression was reversed by NAC. The protective of AS-IV on UVB-induced damage and TLR4 expression was dependent on ROS, as the increase in viability and decrease in TLR4 protein by AS-IV was significantly attenuated by ROS scavenger NAC (1 mM).<br />AS-IV prevent UVB-induced oxidative damage and inflammation by inhibiting TLR4 expression.<br />AS-IV prevent UVB-induced oxidative damage and inflammation by inhibiting TLR4 expression.<br />Wilms tumor is the most frequently occurring renal malignancy in pediatrics. The FTO gene exhibits a featured genetic contribution to cancer development. Nonetheless, its single nucleotide polymorphism (SNP) contribution to Wilms tumor remains unknown.<br />In the present study, 402 Wilms tumor patients and 1198 healthy controls were successfully genotyped for FTO gene SNPs (rs1477196 G&gt;A, rs9939609 T&gt;A, rs7206790 C&gt;G and rs8047395 A&gt;G) using TaqMan SNP genotyping assays. Odds ratios (ORs) and 95% confidence intervals (CIs), generated from unconditional logistic regression, were applied to quantify the effects of FTO gene SNPs on Wilms tumor risk.<br />We found that the rs8047395 A&gt;G polymorphism was significantly correlated with an increased risk for Wilms tumor (GG versus AA/AG adjusted OR = 1.38, 95% CI = 1.04-1.85, p = 0.027). Carriers with 1 and 1-2 risk genotypes are more susceptible of developing Wilms tumor than those without risk genotypes. Stratified analysis of rs8047395 and risk genotypes revealed more significant relationships with Wilms tumor risk in certain subgroups. Preliminary functional annotations revealed that the rs8047395 A allele increases expression levels of the FTO gene as determined by expression quantitative trait locus analysis.<br />The present study provides evidence that rs8047395 may regulate FTO gene expression and thus confer susceptibility to Wilms tumor.

Although investigations into the effects of changing mean climate are widespread, changing patterns of variation in environmental forcing also affect dynamics in complex ways. Using wavelet and time series analyses, we identify a regime shift in the dynamics of a moth species in California from shorter to longer period oscillations over a 34-year census, and contemporaneous changes in regional precipitation dynamics. Simulations support the hypothesis that shifting precipitation dynamics drove changes in moth dynamics, possibly due to stochastic resonance with delayed density-dependence. The observed shift in climate dynamics and the interaction with endogenous dynamics mean that predicting future population dynamics will require information on both climatic shifts and their interaction with endogenous density-dependence, a combination that is rarely available. Consequently, models based on historical data may be unable to predict future population dynamics.Reductive transformations of easily available oxidized matter are at the heart of synthetic manipulation and chemical valorization. The applications of catalytic hydrofunctionalization benefit from the use of liquid reducing agents and operationally facile setups. Metal-catalyzed hydroborations provide a highly prolific platform for reductive valorizations of stable C=X electrophiles. Here, we report an especially facile, broad-scope reduction of various functions including carbonyls, carboxylates, pyridines, carbodiimides, and carbonates under very mild conditions with the inexpensive pre-catalyst Mn(hmds)2 . The reaction could be successfully applied to depolymerizations.<br />To assess the effect of oral anticoagulant (OAC) administration on incidence of dementia in patients with atrial fibrillation (AF) with Systematic review and meta-analysis.<br />We systematically searched the electronic databases including Pubmed, Embase, Cochrane library and ClinicalTrails.gov for relevant articles. The primary outcome was the incidence of dementia. The adjusted risk ratio (RR), odds ratio or hazard ratio were extracted and pooled by the random-effects models. Subgroup analysis was performed according to the setting observational window. Risk of bias was assessed using the Newcastle-Ottawa Scale, while publication bias was assessed by the Begg's and Egger's tests.<br />Nine studies were included in this review (2 prospective and 7 retrospective observational studies, including 613,920 patients). The results presented the significant association between OAC therapy and the reduced risk of dementia compared with no treatment (RR [95% CI]=0.72 [0.60, 0.86], I<br />=97.2%; P=.000). In the subgroup analysis with an observational window, the pooled RR became statistically non-significant (including four studies, RR [95% CI]=0.75 [0.51, 1.10], I<br />=98.8%; P=.000). There is no significant risk of bias and publication bias.<br />This study indicated the protective effect of OAC therapy for dementia in patients with AF. However, the results are limited because of high heterogeneity, inconsistent direction of effect in subgroup analysis with an observational window. Further prospective well-designed study is needed with longer follow-up duration in younger patients.<br />This study indicated the protective effect of OAC therapy for dementia in patients with AF.
