Since the SARS outbreak 18 years ago, a large number of severe acute respiratory syndrome related coronaviruses (SARSr-CoV) have been discovered in their natural reservoir host, bats. Previous studies indicated that some those bat SARSr-CoVs potential to infect humans. Here we report identification and characterization novel coronavirus (nCoV-2019) which caused an epidemic humans, Wuhan, China. The epidemic, started from December 12th, 2019, has 198 laboratory confirmed infections with three...

Coronavirus disease 2019 (COVID-19) most commonly presents with respiratory symptoms, including cough, shortness of breath, and sore throat. However, digestive symptoms also occur in patients COVID-19 are often described outpatients less severe disease. In this study, we sought to describe the clinical characteristics mild severity.We identified one or more (diarrhea, nausea, vomiting), without compared them a group presenting solely symptoms. We followed up clinically until they tested...

Continuous glucose monitoring (CGM) has provided new measures of glycemic control that link to diabetes complications. This study investigated the association between time in range (TIR) assessed by CGM and diabetic retinopathy (DR).A total 3,262 patients with type 2 were recruited. TIR was defined as percentage spent within 3.9-10.0 mmol/L during a 24-h period. Measures variability (GV) well. DR determined using fundus photography graded 1) non-DR; 2) mild nonproliferative (NPDR); 3)...

Contamination with pathogenic and infectious viruses severely threatens human health animal husbandry. Current methods for disinfection have different disadvantages, such as inconvenience contamination of by-products (e.g., chlorine disinfection). In this study, atmospheric surface plasma in argon mixed air plasma-activated water was found to efficiently inactivate bacteriophages, still had strong antiviral activity after prolonged storage. Furthermore, it shown that bacteriophage...

A sensitive assay to identify biomarkers using non-invasively collected clinical specimens is ideal for breast cancer detection. While there are other studies showing disease in saliva cancer, our study tests the hypothesis that discriminatory de novo discovery and validation approaches. This first of this kind no has engaged a biomarker approach In study, case-control independent preclinical validations were conducted evaluate performance translational utilities salivary transcriptomic...

New WHO guidelines recommend ART initiation for HIV-positive persons with CD4 cell counts ≤500 cells/µL, a higher threshold than was previously recommended. Country decision makers must consider whether to further expand eligibility accordingly.We used multiple independent mathematical models in four settings-South Africa, Zambia, India, and Vietnam-to evaluate the potential health impact, costs, cost-effectiveness of different adult criteria under scenarios current expanded treatment...

We present a timely evaluation of the Chinese 2019-nCov epidemic in its initial phase, where demonstrates comparable transmissibility but lower fatality rates than SARS and MERS. A quick diagnosis that leads to case isolation integrated interventions will have major impact on future trend. Nevertheless, as China is facing Spring Festival travel rush has spread beyond borders, further investigation potential spatiotemporal transmission pattern novel intervention strategies are warranted.

Structural variations (SVs) are a major contributor to genetic diversity and phenotypic variations, but their prevalence functions in domestic animals largely unexplored. Here we generated high-quality genome assemblies for 15 individuals from genetically diverse sheep breeds using Pacific Biosciences (PacBio) high-fidelity sequencing, discovering 130.3 Mb nonreference sequences, which 588 genes were annotated. A total of 149,158 biallelic insertions/deletions, 6531 divergent alleles, 14,707...
