Adipocyte-Specific Laminin Alpha 4 Deletion Preserves Adipose Tissue Health despite Increasing Adiposity.

Laminins are heterotrimeric glycoproteins with structural and functional roles in basement membranes. The predominant laminin alpha chain found in adipocyte basement membranes is laminin α4 (LAMA4). Global LAMA4 deletion in mice leads to reduced adiposity and increased energy expenditure, but also results in vascular defects that complicate the interpretation of metabolic data.

Oncostatin M Induces Lipolysis and Suppresses Insulin Response in 3T3-L1 Adipocytes.

Oncostatin M (OSM) is an immune cell-derived cytokine that is upregulated in adipose tissue in obesity. Upon binding its receptor (OSMR), OSM induces the phosphorylation of the p66 subunit of Src homology 2 domain-containing transforming protein 1 (SHC1), called p66Shc, and activates the extracellular signal-related kinase (ERK) pathway. Mice with adipocyte-specific OSMR deletion () are insulin resistant and exhibit adipose tissue inflammation, suggesting that intact adipocyte OSM-OSMR signaling is necessary for maintaining adipose tissue health.

Coercion and the Inpatient Treatment Alliance.

Objective: The importance of building a strong treatment alliance is widely accepted and uncontroversial. Quantitative research suggests that coercive experiences during psychiatric treatment negatively affect the treatment alliance, but reveals little about how this happens or how patients navigate treatment relationships while experiencing coercion during psychiatric treatment.

Methods: Fifty psychiatric inpatients were interviewed at two hospitals.

Oncostatin M Mediates Adipocyte Expression and Secretion of Stromal-Derived Factor 1.

Adipose tissue homeostasis depends on interactions between stromal cells, adipocytes, and the cytokines and chemokines they produce. The gp130 cytokine, oncostatin M (OSM), plays a role in adipose tissue homeostasis. Mice, lacking the OSM receptor (OSMR) in adipocytes ( mice), exhibit derangements in adipose tissue, insulin sensitivity, and immune cell balance.

Adipose Tissue Dysfunction Occurs Independently of Obesity in Adipocyte-Specific Oncostatin Receptor Knockout Mice.

Objective: This study examined the phenotypic effects of adipocyte-specific oncostatin M receptor (OSMR) loss in chow-fed mice.

Methods: Chow-fed adipocyte-specific OSMR knockout (FKO) mice and littermate OSMR controls were studied. Tissue weights, insulin sensitivity, adipokine production, and stromal cell immunophenotypes were assessed in epididymal fat (eWAT); serum adipokine production was also assessed.

Adipogenic Differentiation of Human Adipose-Derived Stem Cells Grown as Spheroids.

Understanding the process of adipogenesis is critical if suitable therapeutics for obesity and related metabolic diseases are to be found. The current study presents proof of feasibility of creating a 3-D spheroid model using human adipose-derived stem cells (hASCs) and their subsequent adipogenic differentiation. hASC spheroids were formed atop an elastin-like polypeptide-polyethyleneimine (ELP-PEI) surface and differentiated using an adipogenic cocktail.

A Review of HIV Pre-Exposure Prophylaxis: The Female Perspective.

When taken consistently, pre-exposure prophylaxis (PrEP) against human immunodeficiency virus (HIV) with once daily tenofovir disoproxil fumarate-emtricitabine (TDF-FTC) has been shown to safely reduce the incidence of HIV infection in high-risk individuals by more than 90%. Yet, according to the Centers for Disease Control and Prevention, there were about 2.1 million new cases of HIV reported worldwide in 2015.

HIV and STI knowledge, testing, and risk among adult crack users in Mexico city: baseline findings from a feasibility study.

Recent research has documented crack cocaine's increasing spread in Mexico, which is likely to contribute to the rapid transmission of HIV and other sexually transmitted infections (STIs). In Mexico, crack use is increasing most rapidly in vulnerable, hard-to-reach populations, where little is known about risk behaviors. This report aims to present baseline data regarding HIV and STI knowledge and testing prevalence from an innovative projection mapping HIV intervention, in which 3-D illusions, animation, and visual text graphics and sound are projected onto buildings with health messages that were designed to disrupt everyday life and connect with the target population.

Loss of Oncostatin M Signaling in Adipocytes Induces Insulin Resistance and Adipose Tissue Inflammation in Vivo.

Oncostatin M (OSM) is a multifunctional gp130 cytokine. Although OSM is produced in adipose tissue, it is not produced by adipocytes. OSM expression is significantly induced in adipose tissue from obese mice and humans.

Probiotics for disease prevention: a focus on ventilator-associated pneumonia.

Objective: To summarize published data regarding the safety and efficacy of probiotics in the prevention of ventilator-associated pneumonia (VAP).

Data Sources: PubMed databases (January 2000-August 2011) were searched and a bibliographic review of published articles was performed to identify original reports of probiotic administration for the prevention of VAP using the search terms probiotics, synbiotics, and ventilator-associated pneumonia.

Study Selection And Data Extraction: Two pilot studies, 2 randomized controlled trials (RCTs), and 1 meta-analysis have addressed probiotic use for VAP prevention and were included in the review.

Primary abdominal gestational choriocarcinoma.

Background: Gestational choriocarcinoma associated with ectopic pregnancy is an extremely infrequent event. Primary abdominal gestational choriocarcinoma has not been previously described.

Case: A pregnant woman presented to the emergency room with 6 days of vaginal spotting.

Inflammation, immune reactivity, and angiogenesis in a severe combined immunodeficiency model of rheumatoid arthritis.

Severe combined immunodeficiency (SCID) mice were engrafted with rheumatoid arthritis (RA) synovium and evaluated to determine whether RA synovial morphology and function were maintained in the RA-SCID grafts. The four major components of RA synovitis, inflammation, immune reactivity, angiogenesis, and synovial hyperplasia persisted in RA-SCID grafts for 12 weeks. Retention of chronic inflammatory infiltrates was demonstrated by histological evaluation and by immunohistology for CD3, CD20, and CD68.
