Many studies have shown insulin resistance (IR) in majority of patients with adrenal incidentaloma. The euglycaemic hyperinsulinaemic glucose clamp technique is still considered as ‘golden standard’ for evaluation of insuline sensitivity. These methods are also complicated, labor-intensive procedure better for small research studies. Today, several surrogate indexes for insulin sensitivity were introduced such as: HOMA, QUIQI or G/IR. Some studies showed that QUIQI h...

Subclinical hyperthyroidism is a biochemical diagnosis defined with suppressed levels of TSH and normal levels of thyroid hormones. One of the main metabolic responses to thyroid hyperfunction is peripheral lipolysis and release of free fatty acids (FFA). The aim of this study was to compare levels of cholesterol, LDL, HDL and triglycerides in persons with subclinical hyperthyroidism to age and BMI matched euthyroid healthy control. We evaluated 45 persons in two groups: 1st g...

Subclinical hypothyroidism is a biochemical diagnosis defined with elevated levels of TSH and normal levels of thyroid hormones. The most common abnormality linked to this condition is hypercholesterolemia. The aim of this study was to search for MSy among the persons with subclinical hypothyroidism which was already proven to have hypercholesterolemia when compared to healthy control. MSy was identified in those with elevated triglycerides (Tgc), reduced HDL and elevated fast...

Several studies show that characteristics of metabolic syndrome are often seen in patients with adrenal incidentaloma. The aim of our study was to evaluate metabolic factors in these patients. 208 patients (148 female and 60 male, age 55.08±11.02 y’s and BMI 27.91±4.6 kg/m2) were admitted and biochemical, endocrine testing were performed. Lipid status: cholesterol 5.77±1.26 mmol/L, triglyceride 1.92±0.98 mmol/L. 113(55%) patients were hypert...

POF is a disease of unclear origin affecting women under age 40. They are at high risk of cardiovascular diseases (CVD).The objective of this study was to compare the lipid status and atherogenic indexes - total cholesterol/high density lipoprotein (TC/HDL) and low density lipoprotein/HDL (LDL/HDL) - of women with POF with healthy women of the same age and the same BMI.We evaluated 54 women in two groups. 1st group: 31 women with P...

Proliferative inflammatory atrophy and prostatic intraepithelial neoplasia are the first signs of prostate cancer. This inflammatory etiology, together with the infiltration of immune cells, could lead to the binding of the cytokines with cancer cells, forming a population that could initiate tumor growth. [1] Androgens also play an essential role in prostate tumor growth, as is well documented. [2] Androgen deprivation therapy is currently the gold standard for hormone-sensit...

Background: In type 1 diabetes (T1D), optimal glycaemic control requires intensive self-management to reduce the risk of complications. While routine downloading and review of blood glucose data is part of clinical practice of healthcare providers in an outpatient setting, patients and families are also educated, advised and encouraged to regularly download and review blood glucose data at home in order to make adjustments to insulin dosing for carbohydrate intake and insulin ...

Benign prostatic hyperplasia and prostate cancer are androgen-dependent diseases. Dihydrotestosterone (DHT) is a 5α-reduced metabolite of testosterone (T), which is the causative factor for the progression of these diseases. The 5α-reductase enzyme (5α-R) converts T to DHT, which is responsible for increasing cell proliferation, and hence inhibition of this enzyme could lead to potential treatments for these afflictions. This study aimed to determine the biologi...

We determined in vitro activity of 17β-estradiol and or progesterone on glutamate conversion to GABA in different GABAergic regions from the brain of castrated and non-castrated rats. The glutamate decarboxylase catalyzes this conversion; there are two different isotypes of glutamate decarboxylase, GAD65 and GAD67. Whereas GAD65 is a membrane enzyme, GAD67 is present in the supernatant obtained after centrifuging to 14,...

Sleep is disturbed in both healthy and pathological aging, so it is essential to consider the role of ovarian hormones in both processes. Studies supporting the natural function of E2 (or elevated FSH) in fragmented sleep are inconsistent because when non-human animals have been used, they have mainly been male. Given this background, this study focused on determining the role of different estradiol and progesterone doses in the intermittent arousals of castrated rats maintain...
