Protein phosphatase 2A (PP2A) is a multimeric serine/threonine phosphatase which has multiple functions. However, the potential involvement of PP2A in insulin’s metabolic signaling pathway is presently unknown. Brain insulin resistant state is characterized by disturbances in transducing the signal from IR/IRS/AKT, changing feeding behaviour and body weight. We showed that diet induced obese rats (DIO) have a marked increase in PP2A protein expression in the hypothalamus....

Objective: A reliable form of androgen substitution therapy in terms of favorable kinetics and tolerance as well as effective restoration of androgenicity is paramount in hypogonadal men. A feasible modality is the intramuscular injection of the long-acting ester testosterone undecanoate (TU).Design: We report data from 22 patients (15 with primary and 7 with secondary hypogonadism) aged 30 to 65 years (mean 43.8±8 years) who received injections of ...

Objective: to study nerve functions in IDDM at an early stage to evaluate the prevalence of neuropathy.Subjects and methods: The study included 20 children with IDDM and 10 healthy subjects as controls. Patients were subjected to clinical evaluation of neuropathic manifestations. Laboratory tests included fasting blood glucose and serum glycated hemoglobin (HbA1c). Electrophysiological study included motor conduction studies of the median and deep perone...

Topiramate (TPM) is an anticonvulsant drug used for the treatment of epilepsy and prophylaxis of migraine. Weight loss is a side effect frequently reported in patients and animal models treated with TPM. Some studies showed that TPM may decrease energy storage, and thus increase energy expenditure and thermogenesis. However, the mechanisms by which TPM reduces body weight are not completely understood. Anorexigenic hormones such as insulin and leptin regulate the activity of d...

Metabolic syndrome (MetS) and benign prostatic hyperplasia (BPH)/lower urinary tract symptoms (LUTS) are often associated. One of their common denominators is hypogonadism. However, testosterone supplementation is limited by concerns for potential prostatic side effects. The objective was to determine whether MetS-associated prostate alterations are prevented by testosterone supplementation. We used a previously described animal model of MetS, obtained by feeding male rabbits ...
