Keystone species are thought to play a critical role in determining the structure and function of microbial communities.As they are important candidates for microbiome-targeted interventions, the identification and characterization of keystones is a pressing research goal.Both empirical as well as computational approaches to identify keystones have
Generation of novel in vitro flexible kidney organoid model to investigate the role of extracellular vesicles in induction of nephrogenesis
Abstract Background During kidney organogenesis, metanephric Jar Set mesenchyme (MM) and ureteric bud (UB) interact reciprocally to form nephrons.Signaling stimuli involved in these interactions include Wnts, growth factors and nano/micro particles.How UB and MM are interacting is not completely understood.Our study investigated the signaling and c

Friction Coefficient of Wet Clutches as a Function of Service Mileage
As a core component for efficient variable speed transmission 30" Gas Cooktop and energy saving, wet clutches are widely used in the transmission systems of energy-saving and new energy vehicles.However, with an increase in the service mileage of the wet clutch, the friction coefficient undergoes alterations.This leads to a deterioration of the con
