Most social distancing videos came from news agencies (68.8%). Hand-washing videos were mostly uploaded by health agencies or academic institutes (52.6%). The videos were less likely to be understandable and actionable and to be of good quality when uploaded by sources other than health agencies or academic institutes. The paucity of adequate information and the limited representation of 'authoritative' sources were concerning. Strategies for harnessing social media as an effective medium for public health education are necessary during pandemics.Neratinib, a tyrosine kinase inhibitor, was very recently approved by USFDA in 2017 as an anticancer drug to treat of HER2 positive breast cancers. The present work provides an account on the development of a validated bioanalytical UPLC-MS/MS method for quantification of neratinib and internal standard (imatinib) in rat plasma and tissue homogenates. A UPLC having a 100 mm C18 column (1.7 μm sized particles) was used with acetonitrile (0.1% formic acid) 2 mMol of ammonium acetate in water (pH 3.5) as the mobile phase. An efficient chromatographic separation was performed and detection was achieved by monitoring precursor-to-product ion transitions with m/z 557.29 → 112.06 for neratinib and m/z 494.43 → 294.17 for IS. The method demonstrated excellent linearity in the spiked plasma drug concentrating ranging between 1 and 800 ng.mL-1 (r2 = 0999), with lower limit of quantification (LLOQ) was observed at 1 ng.mL-1. Intra-assay and inter-assay precision relative standard deviations were found to be within 6.58. Sodiumorthovanadate Mean extraction recovery for neratinib and IS were 99.44 and 99.33%, while matrix effect for neratinib and IS was ranging between -4.35 and - 3.66%, respectively. Overall, the method showed successful applicability in pharmacokinetic analysis of pure various formulations in Wistar rat plasma.

Travelers' diarrhea (TD) is the most common clinical syndrome affecting travelers. This narrative review summarizes key discoveries reported in the last two years related to TD and suggests areas for future research.

A PubMed literature search was conducted for novel data in TD research published between 12/01/2018 and 12/01/2020. Inclusion was based on contribution to epidemiology, etiology, diagnostics, management, and long-term consequences and relevance to public health, discovery and clinical practice.

The initial literature search yielded 118 articles. We retrieved 72 and reviewed 31 articles for inclusion. The findings support our understanding that TD incidence varies by traveler group and environment with students and military-travel remaining moderately high risk, and control of food and water in mass gathering events remain an important goal. The growth of culture-independent testing has led to a continued detection of previously known pathogens, but also an increased detection frequency of nsue and advances in our understanding continue. More research is needed to mitigate risk factors where possible and develop risk-based management strategies to reduce antibiotic usage and its attendant consequences.

Globally, TD remains an important travel health issue and advances in our understanding continue. More research is needed to mitigate risk factors where possible and develop risk-based management strategies to reduce antibiotic usage and its attendant consequences.Bone mineral density (BMD) is a highly heritable complex trait and is a key indicator for diagnosis and treatment for osteoporosis. In the last decade, numerous susceptibility loci for BMD and fracture have been identified by genome wide association studies (GWAS); however, fine mapping of these loci is challengeable. Here, we proposed a new long-range fine-mapping approach that combined super-enhancers (SEs) and microRNAs (miRNAs) data, which were two important factors in control of cell identity and specific differentiation, with the GWAS summary datasets in cell-type-restricted way. Genome-wide SE-based analysis found that the BMD-related variants were significantly enriched in the osteoblast SE regions, indicative of potential long-range effects of such SNPs. With the SNP-mapped SEs (mSEs), 13 accessible long-range mSE-interacted miRNAs (mSE-miRNAs) were identified by integrating osteoblast Hi-C and ATAC-seq data, including three known bone-related miRNAs (miR-132-3p, miR-212-3p and miR-125b-5p). The putative targets of the two newly identified mSE-miRNAs (miR-548aj-3p and miR-190a-3p) were found largely enriched in osteogenic-related pathway and processes, suggesting that these mSE-miRNAs could be functional in the regulation of osteoblast differentiation. Furthermore, we identified 54 genes with the long-range 'mSE-miRNA' approach, and 24 of them were previously reported to be related to skeletal development. Besides, enrichment analysis found that these genes were specifically enriched in the post-transcriptional regulation and bone formation processes. This study provided a new insight into the approach of fine-mapping of GWAS loci. A tool was provided for the genome-wide SE-based analysis and the detection of long-range osteoblast-restricted mSE-miRNAs (https//github.com/Zheng-Lab-Westlake/Osteo-Fine-Mapp-SNP2SE2miRNA).Severe respiratory impairment is a prominent feature of Rett syndrome (RTT), an X-linked disorder caused by mutations in methyl CpG-binding protein 2 (MECP2). Despite MECP2's ubiquitous expression, respiratory anomalies are attributed to neuronal dysfunction. Here, we show that neutral lipids accumulate in mouse Mecp2-mutant lungs, while surfactant phospholipids decrease. Conditional deletion of Mecp2 from lipid-producing alveolar epithelial 2 (AE2) cells causes aberrant lung lipids and respiratory symptoms, while deletion of Mecp2 from hindbrain neurons results in distinct respiratory abnormalities. Single-cell RNA sequencing of AE2 cells suggests lipid production and storage increase at the expense of phospholipid synthesis. Lipid production enzymes are confirmed as direct targets of MECP2-directed nuclear receptor corepressor 1/2 (NCOR1/2) transcriptional repression. Remarkably, lipid-lowering fluvastatin improves respiratory anomalies in Mecp2-mutant mice. These data implicate autonomous pulmonary loss of MECP2 in respiratory symptoms for the first time and have immediate impacts on patient care.
