Metformin is becoming a popular treatment before and during pregnancy, but current literature on in utero exposure to metformin lacks long-term clinical trials mechanistic studies. Current the effects of mature pancreatic β-cells highlights its dual, opposing, protective, or inhibitory effects, depending metabolic environment. However, impact developing human remains unknown. In this study, we ...
Many problems in classification involve huge numbers of irrelevant features. Variable selection reveals the crucial features, reduces dimensionality feature space, and improves model interpretation. In support vector machine literature, variable is achieved by l1 penalties. These convex relaxations seriously bias parameter estimates toward 0 tend to admit too many The current article presents a...
Background & Aim : Intrauterine growth retardation (IUGR) and preterm birth are major determinants of prenatal morbidity and mortality. Standard diagnostic methods like ultrasound are accurate, but they cannot be employed as the screening tools. Lately, it is proposed that there might be an association between IUGR and placental dysfunction so its hormones such as human chorionic gonadotropin...
transforming growth factor-beta (tgf-β) is one of the most important cytokines implicated in growth, differentiation, repair and also the pathogenesis of the lung fibrosis by its stimulatory effect on extracellular matrix deposition. pulmonary epithelial cells are considered as a source of tgf-β in lung. substance p (sp), as a neuroimmunomodulator has elevated levels in inflamed airways and alt...
background: β-thalassemia is a common autosomal recessive disorder resulting from over 200 different mutations of beta globin genes. the aim of the present study was to identify the distribution and frequency of the most common β-thalassemia mutations among the population of isfahan province in central iran. methods: the data presented here were derived from a total of 114 β-thalassemia chro...
Background and Objective: In patients with diabetes, elevated homocysteine levels have been reported to be associated with endothelial dysfunction, insulin resistance, dyslipidemia, poor control of disease, nephropathy, macroangiopathy and oxidative stress. Thus, this observational study was performed to determine the plasma homocysteine level and its correlation with clinical, biochemical and ...
Objective(s): Diabetes is a metabolic disease with an increasing prevalence for which finding new and efficient therapeutic approaches has always been a challenge. Preserving integrity and functionality of pancreatic β-cells as the only source of insulin in the body is such a case. To achieve this goal different cellular targets have been proposed among which pancreatic estrogen receptors have ...

Glioblastoma is the most common malignant brain tumor in adults and characterized by a poor prognosis. Glioma cells expressing O(6)-methylguanine DNA methyltransferase (MGMT) exhibit a higher level of resistance toward alkylating agents, including the standard of care chemotherapeutic agent temozolomide. Here, we demonstrate that long-term glioma cell lines (LTL) as well as glioma-initiating ce...
