background: different investigation showed that 5-methoxypsoralen and 8- methoxypsoralen reduce birth rates in the rats. objective: in this study we worked out the effect of methoxsalen together with ultraviolent a (uva) radiation on mature balb/c mice spermatogenesis. materials and methods: the ld50 standard was determined 160 mg/kg and the uva dose which causes erythema was calculated 0.046 j...

OBJECTIVE Previous studies showed that insulin stimulated directly calcitonin (Ct) secretion in the pig thyroid, while dexamethasone stimulated the production of Ct and Ct mRNA in medullary thyroid carcinoma (MTC) cell lines. The objective of this study was to investigate if hyperinsulinemia during the oral glucose tolerance test (GTT) stimulates Ct secretion in normal subjects as well as to ex...

INTRODUCTION Vitamin E is beneficial in restoring bone histomorphometric parameters in nicotine-treated rats. This study determined the effectiveness of 3 forms of vitamin E in restoring bone metabolism in nicotine-treated rats. MATERIAL AND METHODS Thirty-five male Sprague-Dawley rats were divided into 5 groups: (1) control (C), (2) nicotine cessation (NC), (3) α-tocopherol (ATF), (4) tocotr...

BACKGROUND Methods to identify preventable adverse events typically have low yield and efficiency. We refined the methods of Institute of Healthcare Improvement's Global Trigger Tool (GTT) application and leveraged electronic health record (EHR) data to improve detection of preventable adverse events, including diagnostic errors. METHODS We queried the EHR data repository of a large health sy...

AIMS Alcohol has deleterious influences on glucose metabolism which may contribute to the development of type 2 diabetes mellitus (T2DM). Insulin-like growth factor I (IGF-I) and growth hormone (GH), which interact with insulin to modulate metabolic control, have been shown to be related to impaired glucose tolerance. This study was conducted to assess the possibility that altered circulating I...
