Population aging is a global phenomenon driving research focus toward preventing and managing age-related disorders. Functional hypogonadism (FH) has been defined as the combination of low testosterone levels, typically serum total testosterone below 300-350 ng/dL, together with manifestations of hypogonadism, in the absence of an intrinsic pathology of the hypothalamic-pituitary-testicular (HPT) axis. It is usually seen in middle-aged or elderly males as a product of aging and multimorbidity.

Canagliflozin-with the patent number WO2011142478A1- belongs to a novel class of antidiabetic drugs known as SGLT2 inhibitors, which has been approved by FDA in March 2013. This medication acts through the inhibition of glucose reabsorption in the kidney resulting in glucosuria and thus lowering of glucose blood levels. There are several phase III clinical ongoing trials involving this new class of medications.

Primary Objective: Granulocyte-colony stimulating factor (G-CSF) is used for the mobilization of bone marrow and endothelial progenitor cells, though G-CSF-induced inflammation may cause endothelial dysfunction. We examined the effects of G-CSF on endothelium, C-reactive protein (CRP), tumour necrosis factor-alpha (TNF-alpha) and anti-inflammatory cytokines namely interleukin 10 (IL-10).

Research Design: We studied 60 women with breast cancer, who were randomized to either subcutaneous G-CSF (5 microg/kg), o.

Current thinking supports the notion that several inflammatory proteins intervene with endothelium and haemostatic factors leading to plaque formation and rupture. Of these, C-reactive protein (CRP), monocyte/macrophage colony-stimulating factor (MCSF) and interleukin-6 (IL-6) promote atherogenesis by inducing monocyte-macrophage activation, foam cell formation, platelet activation, tissue factor expression, release of other procoagulant cytokines or downregulation of atheroprotective cytokines such as interleukin 10 and transforming growth factor b-1 (TGFb-1). CRP, MSCF and IL-6 are interrelated and have been found in increased blood concentrations in CAD.

Background: Circulating anticardiolipin antibodies (aCL) may cause endothelial dysfunction. We investigated whether aCL are related to platelet activation, thrombin generation and daily-life ischaemia in patients with chronic coronary artery disease (CAD).

Methods: We measured (medians 25th-75th percentile) IgG, IgM, IgA aCL serum levels (Arbitrary Elisa Units, AEU), prothrombin fragments (F1+2, nmol/l), 24 h urine excretion of 11-dehydrothromboxane B2 (11-DHTXB2, ng/mg creatinine) creatine kinase (CK) and its cardiac isoenzyme CK-MB (IU/l) in 60 patients with angiographically documented CAD and in 40 age and sex matched controls.

Diabetes mellitus type 2 (DM type 2) is associated with depressive symptomatology and intermittent hyperfunction of the hypothalamic-pituitary-adrenal (HPA) axis. DM type 2 is also accompanied by increased tissue levels of angiotensin II (Ang II), which stimulates the HPA axis through the Ang II type 1 receptors (AT1). We investigated the effect of candesartan, an angiotensin receptor blocker (ARB) that crosses the blood brain barrier, on the activity of the HPA axis and on the affect of 17 patients with DM type 2, aged 40-65 years, who were treated with 4 mg/day candesartan per os for at least 3 months.

Endothelial dysfunction is considered to be the first step in atherogenesis as well as a predictor of adverse cardiovascular events in patients with coronary artery disease (CAD), while endothelial function improvement is associated with improved clinical outcome. Nebivolol is a beta1-adrenoreceptor antagonist with an independent beneficial action on endothelial function, increasing nitric oxide bioavailability. The aim of the present study was to examine the effects of nebivolol on endothelial function in the brachial artery in patients with CAD compared with another selective beta1 adrenergic receptor antagonist, atenolol.
