Improving the sensitivity of protein-protein interaction detection and protein structure probing is a principal challenge in cross-linking mass spectrometry (XL-MS) data analysis. In this talk, we pro...
After decades of fundamental scientific and drug discovery research, Alzheimer’s disease has remained inscrutable and incurable, with a bare minimum of therapeutic progress. But in a new review articl...
We consider a joint production-service planning problem with demand uncertainty, where the manufacturer aims to determine the portfolio of products with the associated service levels and the capacity ...
自从科学家们研究清楚CRISPR-Cas系统的作用机理并将其应用于真核细胞的基因编辑后,相关工具的开发、改造和应用呈爆发式增长,成为生物学研究的重要手段。目前主要的CRISPR编辑工具有Cas9、Base editor (BE)和Prime editor (PE),及衍生的各种工具。CRISPR编辑工具在基因功能研究、转录调控、表观遗传修饰和基因治疗等众多研究领域具有重要应用和广阔前景。但是,CR...
Unlike electrons, quarks cannot wander freely in ordinary matter. They are confined by the strong force within hadrons such as the protons and neutrons that make up atomic nuclei. However, at very hig...
近日,国际地球物理Nature Index期刊《Journal of Geophysical Research: Solid Earth》刊出了中国地质大学关于多孔介质二维和三维之间输运机理方面的最新研究成果:基于分形几何的二维截面分析确定毛细管压力曲线:多孔介质的二维和三维孔隙结构之间的桥梁(Capillary Pressure Curve Determination Based on a 2-...
Background: The ω-6 (n–6) to ω-3 (n–3) fatty acid (FA) ratio (n–6:n–3 ratio) was previously shown to be a predictor of executive function performance in children aged 7–9 y.
Background: Aging is associated with a progressive decline in vitamin B-12 status. Overt vitamin B-12 deficiency causes neurologic disturbances in peripheral and central motor and sensory systems, but...
This study assessed the influence of genetic type (Embden-Anser anser, EE; Toulouse-Anser anser, TT and F1 cross, ET) for meat characteristics (carcass, meat quality and fatty acid (FA) profiles), of ...
A study was conducted to assess the genetic diversity among Simmental Cross cattle in West Sumatra using microsatellite DNA markers. A total of 176 individual cattle blood samples was used for obtaini...
Raymond K. Cross, Jr., M.D.,M.S. is a board certified Gastroenterologist and Associate Professor of Medicine, Division of Gastroenterology and Hepatology, at the University of Maryland School of Medic...
Background: Age-related progressive loss of muscle mass is an increasing problem in our aging society, affecting physical ability, risk of falls, and need for health care. Telomere length has been rec...
The study of proteins and protein complexes using chemical cross-linking followed by the MS identification of the cross-linked peptides has found increasingly widespread use in recent years. Thus far,...
This paper is concerned with properties of maximal solutions of the Ricci and cross curvature flows on locally homogeneous three-manifolds of type SL2(R). We prove that, generically, a maximal solut...
Factor analysis is over a century old, but it is still problematic to choose the number of factors for a given data set. The scree test is popular but subjective. The best performing objective method...
