Article Synopsis
  • Osteoporosis is a common issue among postmenopausal women, leading to increased risk of fractures and associated health problems. Raloxifene hydrochloride is a treatment option that boosts bone density without affecting the breast or uterus.
  • This study investigated the impact of raloxifene on various biochemical markers in 22 postmenopausal women with osteoporosis over 12 weeks, comparing results with a control group of non-osteoporotic women.
  • Results showed improved serum osteocalcin, parathyroid hormone, and vitamin D levels in patients, but no significant change in key inflammatory cytokines, with levels of IL-6 and TGF-beta1 becoming lower than those in the control group after treatment.*

Acromegaly is associated with a two to three-fold increase in mortality related predominantly to cardiovascular disease. The excess mortality is associated most closely with higher levels of growth hormone (GH). Survival in acromegaly may be normalized to a control age-matched rate by controlling GH levels; in particular, GH levels less than 2.

Background: In West of Scotland Coronary Prevention Study (WOSCOPS), development of type 2 diabetes mellitus (DM) was found to decrease by 30% in pravastatin-treated patients. In the study, it is suggested that pleiotropic effects of pravastatin may be responsible too as well as its lipid lowering effect.

Objective: The aim of this study was to assess the effects of pravastatin treatment on the insulin resistance in patients with metabolic syndrome with impaired glucose tolerance (IGT), by Homeostasis Model Assessment (HOMA) test, insulin sensitivity indices and glucose half activation time (glucose t1/2).

Homocysteinemia is an independent risk factor for cardiovascular disease, but information on its association with type 2 diabetes and mild renal dysfunction is limited. Plasma total homocysteine (tHcy) concentration is partly determined by renal plasma clearance. Serum cystatin C (Cys C) concentration has been introduced as a marker of renal function, specifically as an indicator of glomerular filtration rate (GFR).

Objective: Biochemical evidence suggests that the oxidative damage of the lens proteins is involved in the genesis of senile cataract and the development of diabetes-related pathologic changes such as the formation of cataracts. In particular, lens proteins are subject to extensive oxidative modification. Oxidative damage either decreases the antioxidant capacity or decreased antioxidant capacity results in oxidative damage.
