Estrogen deficiency is considered to be the main cause of increased appetite and increased weight in postmenopausal women. In this period, reduced secretion of melatonin (MEL) was also observed. The aim of the study was to evaluate the secretion of melatonin, 17-β estradiol and follicle-stimulating hormone (FSH) in relation to body mass index (BMI) in pre- and postmenopausal women. The study in...

Serum progesterone and estradiol-17β levels were estimated in Nili Ravi buffaloes (n=190) with and without fetal membranes retention in three agro-ecological zones of Punjab. The results showed that serum progesterone concentration was significantly higher (P<0.05) in buffaloes with retention of fetal membranes (RFM) compared to buffaloes without retention of fetal membranes (NRFM). The compari...

PURPOSE To evaluate the peripapillary and perifoveal retinal perfusions of young healthy eyes with a tessellated fundus using optical coherence tomography (OCT) angiography. METHODS Thirty-five Chinese subjects with a tessellated fundus and 35 subjects without a tessellated fundus from a population-based cross-sectional study in Shanghai were included. All participants underwent OCT angiograp...

BACKGROUND In aortic stenosis (AS), the combination of risk factors can progressively lead to an increased arterial rigidity, which can be evaluated by the carotid artery and aortic stiffness (β index). The aim of this study was to investigate the relationship between carotid and aortic β index, left ventricular (LV) function, plasma brain natriuretic peptide (BNP) level, and symptoms in patien...

introduction: postoperative neurological deficit is the most devastating complication after thoracoabdominal aortic aneurysm repair. despite demonstrated neuroprotective effects of estradiol, its protective efficacy against spinal cord ischemia-reperfusion and underlying mechanisms are not yet elucidated. methods: two groups, each of 10 new zealand white male rabbits, were studied. control grou...

OBJECTIVES Osteoporosis is a systemic skeletal disease with a consequent increased risk of fracture, decreased quality of life and economic burdens for both the patients and health care system. While Dual energy X-Ray absorptiometry remains the gold standard for assessment of bone mineral density, it cannot be requested for all patients for obvious reasons. By determining other variables that m...

BACKGROUND Augmentation index, a marker of central wave reflection, is influenced by age, sex, height, blood pressure, heart rate, and arterial stiffness. However, the detailed haemodynamic determinants of augmentation index, and their relations, remain uncertain. We examined the association of augmentation index with vascular resistance and other haemodynamic and non-haemodynamic factors. ME...

This article describes gas chromatography-flame ionization detection method for determination of 17 β-estradiol in rabbit plasma. 17 β-estradiol and internal standard progesterone were extracted from plasma using liquid-liquid extraction method. Linearity was found between 0.25 and 20 μg/ml (r(2)=0.994) for plasma samples. Intra-day and inter-day precision, expressed as the relative standard de...
