Evaluating the Effect of Hypoxia on Human Adult Mesenchymal Stromal Cell Chondrogenesis In Vitro A Systematic Review.

Human adult mesenchymal stromal cells (MSCs) from a variety of sources may be used to repair defects in articular cartilage by inducing them into chondrogenic differentiation. The conditions in which optimal chondrogenic differentiation takes place are an area of interest in the field of tissue engineering. Chondrocytes exist in vivo in a normally hypoxic environment and thus it has been suggested that exposing MSCs to hypoxia may also contribute to a beneficial effect on their differentiation.

Cell type-specific mechanistic target of rapamycin-dependent distortion of autophagy pathways in lupus nephritis.

Pro-inflammatory immune system development, metabolomic defects, and deregulation of autophagy play interconnected roles in driving the pathogenesis of systemic lupus erythematosus (SLE). Lupus nephritis (LN) is a leading cause of morbidity and mortality in SLE. While the causes of SLE have not been clearly delineated, skewing of T and B cell differentiation, activation of antigen-presenting cells, production of antinuclear autoantibodies and pro-inflammatory cytokines are known to contribute to disease development.

Predictors of cognitive behavioral therapy outcomes for insomnia in veterans with post-traumatic stress disorder.

Background: Insomnia is a well-recognized co-morbid condition in veterans with post-traumatic stress disorder (PTSD) with negative personal and social consequences. Cognitive behavioral therapy (CBT) is considered an efficacious treatment, yet little attention has been devoted to treatment response in this population. The aim of this study was to identify factors that may predict clinical response to CBT for insomnia (CBT-I) in veterans with PTSD.

An infected urachal cyst presenting as an acute abdomen - A case report.

Introduction: An infected urachal cyst is one of a spectrum of presentations of urachal pathology, all of which are rare in adulthood.

Presentation Of Case: We report the case of a 45-year-old obese Russian lady who presented with a 2-week history of suprapubic pain radiating to the right iliac fossa. Although previously fit and well, she had a history of 17 miscarriages.

Bare below elbows: does this policy affect handwashing efficacy and reduce bacterial colonisation?

Introduction: UK Department of Health guidelines recommend that clinical staff are 'bare below the elbows'. There is a paucity of evidence to support this policy. One may hypothesise that absence of clothing around wrists facilitates more effective handwashing: this study aims to establish whether dress code affects bacterial colonisation before and after handwashing.
