Recent data on the coronavirus disease 2019 (COVID-19) outbreak caused by severe acute respiratory syndrome 2 (SARS-CoV-2) has begun to shine light impact of liver. But no studies date have systematically described liver test abnormalities in patients with COVID-19. We evaluated clinical characteristics COVID-19 abnormal results.Clinical records and laboratory results were obtained from 417 laboratory-confirmed who admitted only referral hospital Shenzhen, China January 11 February 21, 2020...
Abstract Background The clinical characteristics of novel coronavirus disease (COVID‐2019) patients outside the epicenter Hubei Province are less understood. Methods We analyzed epidemiological and features all COVID‐2019 cases in only referral hospital Shenzhen City, China, from January 11, 2020, to February 6, followed until March 2020. Results Among 298 confirmed cases, 233 (81.5%) had been Hubei, while 42 (14%) did not have a clear travel history. Only 218 (73.15%) fever as initial...
Acute hepatitis E (AHE) poses a significant threat to global public health, particularly among women of childbearing age (WCBA), who are at heightened risk for severe pregnancy-related complications. This study aimed delineate the temporal trends and project future incidence AHE in WCBA, providing insights crucial targeted prevention control strategies.
Abstract Background A new type of novel coronavirus infection (COVID-19) occurred in Wuhan, Hubei Province. Previous investigations reported patients Wuhan city often progressed into severe or critical and had a high mortality rate.The clinical characteristics affected outside the epicenter province are less well understood. Methods All confirmed COVID-19 case treated Third People’s Hospital Shenzhen,from January 11, 2020 to February 6, 2020, were included this study. We analyzed...
Support vector machine (SVM) is a popular supervised learning classifier and has found extensive applied in many fields, including biological sciences, disease detection, health clinical cancer classification, more. However, the major challenge faced by SVM its high-computational complexity, which becomes bottleneck for large-scale SVM. To reduce computational we design novel truncated squared loss function to get <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML"...
This article presents recent progress in the conversion of propargyl vinyl ethers into heterocyclic scaffolds and how this goal can be reached a diversity-oriented approach. The also includes examples transformations where ether moieties are formed situ. Furthermore, related reactions transforming amines to heterocycles discussed.
Lewis acid or Brønsted catalyzed reactions of vinylidene cyclopropanes (VDCPs), 1, with activated carbon-nitrogen, nitrogen-nitrogen, and iodine-nitrogen double-bond-containing compounds have been thoroughly investigated. We found that pyrrolidine 1,2,3,4-tetrahydroquinoline derivatives can be formed in good yields the VDCPs 1 ethyl (arylimino)acetates 2 by a [3+2] cycloaddition intramolecular Friedel-Crafts reaction pathway. Based on these results, we carbon-nitrogen nitrogen-nitrogen...
In Brief Background Male clients of female sex workers (FSWs) serve as a potential bridge human immunodeficiency virus (HIV) to the general population. Little is known about characteristics and risk factors for HIV infection among male patronizing FSWs in Hekou County, Yunnan Province southern China bordering with Vietnam. Methods were recruited through outreach study staff, referrals by Vietnamese their bosses, snowball sampling. Each participant completed questionnaire survey donated blood...
Catalyzed by the first-generation Grubbs' ruthenium complex, tandem intramolecular/intermolecular metathesis of 1,6-enynes bearing a cyclopropene ring took place smoothly to produce 3-pyrroline derivatives in satisfactory yields via ring-opening/ring-closing/cross-metathesis processes.
The common spatial pattern (CSP) is a very effective feature extraction method in motor imagery based brain computer interface (BCI), but its performance depends on the selection of optimal frequency band. Although lot research works have been proposed to improve CSP, most these problems large computation costs and long time. To this end, three new methods CSP non-convex log regularization are paper. Firstly, EEG signals spatially filtered by then proposed. We called them CSP-wavelet,...
Background: Salvianolic acid B (Sal B) is one of the main active ingredients Sa lvia miltiorrhiza Bunge . In China, many traditional Chinese medicines have been modified into injections for higher bioavailability and better efficacy. injection has widely used in clinic. Objective: This phase 1, randomized, double-blind, placebo-controlled, single-center study aimed to evaluate safety, tolerance, pharmacokinetics Sal healthy volunteers. Methods: For single-ascending-dose study, forty-seven...
