Abstract In the adult vertebrate intestine, multi-potent stem cells continuously generate all of the epithelial cells throughout the adulthood.While it has long been known that the frog intestine is formed via the development of adult intestinal stem cells during thyroid hormone (TH)-dependent metamorphosis, the basic structure of the adult intesti
Fossil sites from Brazil have yielded specimens of spinosaurid theropods, among which the most informative include the cranial remains of Irritator, Angaturama, and Oxalaia.In this work some of their craniodental features are reinterpreted, providing new data for taxonomic and evolutionary Curler issues concerning this particular clade of dinosaurs
ABSTRACT Coronavirus disease 2019 (COVID-19) has wreaked havoc across the globe; although the number of cases in Africa remains lower than in other regions, it is on a gradual upward trajectory.To date, COVID-19 cases have been reported in 54 out of 55 African countries.However, due to limited severe acute respiratory syndrome coronavirus Accessori
The germinal center (GC) reaction is a key feature of adaptive humoral immunity.GCs represent the site where mature B cells refine their B-cell receptor (BCR) and are selected based on the newly acquired affinity for the antigen.In the GC, B cells undergo multiple cycles of proliferation, BCR remodeling by immunoglobulin somatic hypermutation (SHM)
To improve the Skin Treatment starting performance of the P2.5 plug-in hybrid electric vehicles with a wet dual-clutch transmission, an adaptive starting control strategy is presented in this paper, which controls the two clutches simultaneously involved in the starting process.A fuzzy controller is designed to identify the starting intention and d
