UnknownTwo New Aristolochic Acid Analogues from the Roots of Aristolochia contorta with Significant Cytotoxic Activity.
Twelve compounds, including two new aristolochic acid analogues with a formyloxy moiety (9-10) and 10 known aristolochic acid derivates (1-8 and 11-12), were obtained from the roots of Aristolochiacontorta. Their structures were elucidated using extensive spectroscopic methods. Their c...

UnknownLasting antibody and T cell responses to SARS-CoV-2 in COVID-19 patients three months after infection.
The dynamics, duration, and nature of immunity produced during SARS-CoV-2 infection are still unclear. Here, we longitudinally measured virus-neutralising antibody, specific antibodies against the spike (S) protein, receptor-binding domain (RBD), and the nucleoprotein (N) of SARS-CoV-2, as well as T...

UnknownEndovascular treatment for cerebral venous thrombosis: a multicenter study in China.

Background

Endovascular treatment (EVT) is gaining popularity for the management of severe forms of cerebral venous thrombosis (CVT), but the evidence supporting its efficacy and safety is limited.

Methods

This multicenter study included patients with CVT admitted to 104 hospitals in ...

UnknownDetection of disk-jet coprecession in a tidal disruption event.
Theories and simulations predict that intense space-time curvature near black holes bends the trajectories of light and matter, driving disk and jet precession under relativistic torques. However, direct observational evidence of disk-jet coprecession remains elusive. Here, we report the most compel...

UnknownMeta-analysis of genome-wide association studies in East Asian-ancestry populations identifies four new loci for body mass index.
Recent genetic association studies have identified 55 genetic loci associated with obesity or body mass index (BMI). The vast majority, 51 loci, however, were identified in European-ancestry populations. We conducted a meta-analysis of associations between BMI and ∼2.5 million genotyped or imputed s...

UnknownGenome-wide association studies in East Asians identify new loci for waist-hip ratio and waist circumference.
Sixty genetic loci associated with abdominal obesity, measured by waist circumference (WC) and waist-hip ratio (WHR), have been previously identified, primarily from studies conducted in European-ancestry populations. We conducted a meta-analysis of associations of abdominal obesity with approximate...

UnknownContinual Decline in Azole Susceptibility Rates in Candida tropicalis Over a 9-Year Period in China.

Background

There have been reports of increasing azole resistance in Candida tropicalis, especially in the Asia-Pacific region. Here we report on the epidemiology and antifungal susceptibility of C. tropicalis causing invasive candidiasis in China, from a 9-year surveillance st...

UnknownAssociation analyses of East Asian individuals and trans-ancestry analyses with European individuals reveal new loci associated with cholesterol and triglyceride levels.
Large-scale meta-analyses of genome-wide association studies (GWAS) have identified >175 loci associated with fasting cholesterol levels, including total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG). With differen...

UnknownIdentification of type 2 diabetes loci in 433,540 East Asian individuals.
Meta-analyses of genome-wide association studies (GWAS) have identified more than 240 loci that are associated with type 2 diabetes (T2D)1,2; however, most of these loci have been identified in analyses of individuals with European ancestry. Here, to examine T2D risk in East Asian individ...

UnknownUltrahigh-energy gamma-ray emission associated with black hole-jet systems.
Black holes (BHs), one of the most intriguing objects in the universe, can manifest themselves through electromagnetic radiation initiated by the accretion flow. Some stellar-mass BHs drive relativistic jets when accreting matter from their companion stars, forming microquasars. Non-thermal emission...
