Mechanisms underlying cold-induced immunosuppression remain unclear. Here we found that cold exposure leads to transient receptor potential melastatin 8 (TRPM8)-dependent, renin-angiotensin-aldosterone system (RAAS)-mediated hypertension, which subsequently induces small molecule and fluid extravasation, increases plasma Ig levels, and elicits immunosuppression. An effect is similar to the clinically-used immunosuppressive treatments of intravenous immunoglobulin (IVIg) against various inflammatory diseases, such as immune thrombocytopenia (ITP)...

In the present study, we purified α-amino acid ester hydrolase (AEH) from cell-free extracts of the Stenotrophomonas maltophilia strain HS1. The approximately 70-kDa AEH from S. maltophilia HS1 (SmAEH) was homogeneous in sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) analyses, and was present as a tetramer in gel-filtration experiments. The activity of the SmAEH enzyme was then determined by monitoring the synthesis of the antihypertensive agent dipeptide isoleucyl-tryptophan (Ile-Trp) from isoleucyl methyl ester (Ile-OMe) and tryptophan (Trp)...

The African wild olive ( Olea europaea subsp. africana ) is traditionally used as a hypotensive agent. Herb-drug interactions may result from the concurrent use of herbal medicines and conventional prescription drugs. This aspect was investigated by determining the effect of the extract on the in vitro intestinal epithelial permeation of selected hypotensive drugs using the Caco-2 cell culture model. The phytochemical profiles of leaf extracts of African wild olive from different localities in South Africa were compared, since efficacy is determined by the chemical composition...

INTRODUCTION: Hypertension is the leading cardiovascular risk factor globally, associated with a high morbidity and mortality. The high prevalence of hypertension in sub-Saharan Africa (SSA) is associated with contrastingly low awareness, treatment and control rates. Adherence to medication remains a major determinant of optimal blood pressure control. This systematic review aims to determine the prevalence, and factors associated with adherence to antihypertensive pharmacotherapy among patients with hypertension in SSA...

The presence of hypertension in individuals with type 2 diabetes augments the risk for cardiovascular morbidity and mortality. In this regard, data support that management of hypertension in this high-risk population is a critical risk reduction strategy. In recent years, a number of work groups have redefined hypertension, management strategies, and targets. In this context, there is still considerable discussion on an appropriate target for blood pressure in the diabetic population. However, despite this discussion on target blood pressure, it is widely recognized that there is considerable residual risk for heightened cardiovascular events in the hypertensive, diabetic population despite widespread awareness and treatment...

BACKGROUND: In general, women have lower risk for cardiovascular disease. We tested whether this sex-specific protection persists also in the presence of hypertensive left ventricular hypertrophy (LVH). METHODS: 12,329 women and men with hypertension and free from prevalent cardiovascular disease enrolled in the prospective Campania Salute Network registry were followed over a median of 4.1years. Subjects were grouped according to the absence or the presence of LVH identified by echocardiography using validated sex-specific cut-off values of LV mass index (>47g/m2...
