Fixation is required to reinforce reconstituted collagen for orthopedic bioprostheses such as tendon or ligament replacements.Previous studies have demonstrated that collagen fibers cross-linked by the biocompatible dicatechol nordihydroguaiaretic acid (NDGA) have mechanical strength comparable to native tendons.This work focuses on investigating f
INTRODUCTION: Neonatal Sepsis (NNS) is a public health problem which causes death or disability unless appropriate antibiotic treatment is given promptly.Globally, sepsis is an important cause of morbidity and mortality in neonates despite recent progress in health care delivery.We assessed the factors associated with culture proven sepsis among ne
Follicular helper CD4+ T cells (TFH) are highly permissive Little Friend Buildings to HIV and major foci of virus expression in both untreated and treated infection.Follicular regulatory CD4+ T cells (TFR) limit TFH numbers and function in vitro and in vivo.We evaluated the hypothesis that TFR suppress HIV replication in TFH using a well-establishe
Abstract In this study, based on the classical Archard adhesion wear theory, a three-dimensional finite element model was established, with the aim of simulating the failure process of self-lubricating spherical plain bearings in the swinging wear condition.The results show that the self-lubricating spherical plain bearings go through two different
