Background and Aims: Diabetes causes immeasurable personal suffering and costs to the society, though diabetes and its complications are largely preventable. There are proven, affordable preventions available, that can stop or delay diabetes/complication development. Political Declaration adopted by UNO stresses importance of educational measures to promote health education and literacy. IMAGE Project/Toolkit on Type 2 Diabetes Prevention in Europe outlines education as corner...

Introduction: Octylphenol (OP) is a degradation product of alkylphenol ethoxylates that are widely used to in rubber, pesticides and paints. Bisphenol A (BPA) is an organic compound with two functional phenol groups and used to make polycarbonate plastic and epoxy resins, along with other applications. OP and BPA are known as endocrine disruptors that can induce inappropriate estrogenic action, and may disturb natural calcium metabolism. In the present study, the effects of OP...

Introduction: Parabens, esters of para-hydroxybenzoic acid, are widely used as an antimicrobial agent in the cosmetic products and pharmaceutical industries. Recently, it has been reported that parabens including methyl-, ethyl-, propyl-, butyl-, isopropyl-, and isobutylparaben act as xenoestrogens, a class of endocrine disruptors. In this study, we hypothesized that parabens may disrupt ovarian follicle maturation in female rats during the neonatal period.<p class="abstex...

The aim of the current study was to determine whether the porcine ovary was capable of metabolizing polybrominated diphenyl ether – BDE-47, which is the most abundant congener found in wildlife and in humans. It have been showed by us that this congener disrupt ovarian function by direct action on steroidogenesis. In the current study we analyzed the activity and expression of enzymes involved in phase I (CYP1A1 and CYP2B1/2) and phase II (SULT1A and COMT) of BDE-47 metab...

Breast cancer remains the leading cause of cancer-related death in Australian women. Up to 70% of post-menopausal tumours are estrogen-receptor positive (ER+), dependent on estrogen for continued growth and proliferative advantage. Adjuvant anti-estrogen therapies are considered the cornerstone approach to the treatment of such tumours, and research is ongoing to maximize its effectiveness. The major source of estrogens for ER+ breast cancers is local conversion of androgen pr...

Introduction: Preeclampsia is a pregnancy-specific disease characterized by de novo development of concurrent hypertension, proteinuria and oxidative stress in placenta. Hypoxia occurs during the development of placenta in the first trimester and is implicated in trophoblast differentiation. The oxidative stress, resulting from deficient remodeling of spiral arteries, is an important inducer of preeclampsia. The potassium-dependent sodium/calcium exchangers including NC...

Introduction: Preeclampsia is a pregnancy-specific disease characterized by de novo development of concurrent hypertension, proteinuria and oxidative stress in the placenta. Hypoxia occurs during the development of placenta in the first trimester and is implicated in trophoblast differentiation. Last trimester of gestation, the calcium and mineral transport from mother to fetus are dramatically increased in response to the accelerated demand for bone mineralization in t...

Cimetidine, an antagonist of histamine H2-receptors used for treatment of gastric ulcers, exerts antiandrogenic effect. In testes, cimetidine causes histopathological disorders in the seminiferous tubules and impairs spermatogenesis. Additionally to testosterone, Leydig cells (LC) produce several paracrine factors, including EG–VEGF (endocrine gland-derived vascular endothelial growth factor) which participates in the testicular microvasculature control. Regarding the imp...

Background: According to the 6th National Nutrition Health Survey, the Filipino is generally unfit, with increasing incidences of major risk factors for cardiovascular disease like hypertension, abnormal lipid profile, obesity and diabetes over the last 5 years. Orlistat, a lipase inhibitor is one of the medications used to facilitate weight loss in obese patients. Given that weight loss is known to be associated with an improvement in the serum lipid profile, concurrent impro...

Introduction: Hypothalamic damage in craniopharyngiomas (CP) is associated with poor functional outcome. Data on quality of life (QoL) in CP on complete hormone replacement, including GH, is missing. The aim of this study was to assess QoL and neurocognitive function in childhood onset (CO) CP on complete hormone substitution.Methods and design: Forty-two (20 women) patients, aged ≥17 years were recruited from the South Medical Region of Sweden (po...
