Filter by:Not many studies examined genetic determinants of obesity in women. As pre-menopausal and post-menopausal women appear to have different propensities for fat deposition, genetic loci linked with obesity-related phenotypes might be different by menopausal status. So far, there is no large scale of genetic study deciphering common obesity focusing on women population to examine the contributions of aging and change in menopausal status to obesity in Taiwan. The investigators propose this study to compare phenotypic profiles of obesity and cardio-metabolic factors in pre-menopausal and post-menopausal women. The study will examine the contributions of aging and change in menopausal status to the changes of obesity-related traits during the transition from pre-menopause to post-menopause period, and will evaluate the contribution of genetic susceptibility on body fat deposition among women at different stage of menopause.
The purpose of this study is to determine if armodafinil improves quality of life and is an effective treatment of fatigue in symptomatic perimenopausal and postmenopausal women.
The cohort of post-menopausal women represents a group of very-difficult-to-treat patients in whom a more powerful approach is required in order to improve the disappointing response rate. Thus the addition, in patients with previous failure to PEG/RBV treatment or in naïve patients, of a powerful drug like Boceprevir could greatly improve SVR rate as suggested by the results of SPRINT_2 trial in whom Boceprevir addition determined a 30% improvement in SVR rate in difficult gt 1 patients of African descent versus standard PEG IFN/Ribavirin therapy or by those of RESPOND-2 that showed the same percent improvement of RGT-retreatment with Boc/P/R of previous failure of standard therapy. Goal of the study is to verify whether the addition of a 24-week treatment with boceprevir to standard antiviral therapy with Peg IFN and ribavirin will increase the rate of SVR in patients difficult to treat, such as HCV-positive women in post-menopausal women with genotype 1, not only those who have never been treated, but also in those who have not responded to previous treatment with peginterferon and ribavirin (Riba).
The purpose of this study is to test the effects of Femarelle ( a plan-derived SERM) on hot flushes and quality of life in menopausal women. Our hypotheses are that compared to placebo, Femarelle reduces the daily number of hot flushes and their severity and also improves the quality of life as measured by validated dairies and questionnaires.
Calcitonin, calcitonin gene-related peptides (CGRPs), adrenomedullin, and amylin belong to a unique group of peptide hormones important for the regulation of calcium balance, neurotransmission, cardiovascular homeostasis, and glucose metabolism. We, the investigators at Chang Gung Memorial Hospital, recently identified intermedin as a novel peptide hormone belonging to this unique peptide ligand family. Adrenomedullin is a 52-amino-acid peptide and is one of the most potent vasodilators. Plasma adrenomedullin is elevated in a variety of pathological conditions such as hypertension, renal failure, heart failure, and septic shock. CGRPα and CGRPβ are 37-amino acid neuropeptides; primarily release from sensory nerves; and play important roles in regulating peripheral vascular tone and controlling blood flow in various organs. Human mature intermedin encodes 40-amino-acid and is expressed mainly in the adrenocorticotrophs of the anterior and intermediate pituitary lobe. Intermedin signals through calcitonin receptor-like receptor (CRLR)/receptor activity-modifying protein (RAMP) receptor complexes, and CRLR/RAMP signaling has been proven to be critical for vascular tone regulation. Based on this finding, we had documented that intraperitoneal administration of intermedin dose-dependently suppressed blood pressure in normal Sprague-Dawley rats. In addition, our preliminary in vitro and in vivo studies demonstrated that ovariectomy lead to a tenfold reduction of intermedin transcript expression in the pituitary in rats whereas subsequent estrogen treatment increased pituitary intermedin expression to a level similar to that of intact rats. Taken together, we propose that pituitary-derived intermedin is regulated by estrogen and exhibits potent hypotensive effects. To address this hypothesis, in Specific Aim 1, we will investigate the regulation of secretion and expression of intermedin in vitro and in vivo using cultured pituitary cells and oophorectomized rats. In Specific Aim 2, we will study the molecular mechanism by which estrogen stimulates intermedin gene expression. In Specific Aim 3, to demonstrate that the estrogen-dependent regulation of intermedin represents a critical link in the regulation of blood pressure in women, we will study the relationship between blood pressure and blood intermedin levels using a cross-sectional study. Our studies will provide a better understanding of the mechanisms by which sex hormones modulate blood pressure and open a new window for postmenopausal hypertension treatment.
This study will examine whether estrogen administration in postmenopausal women can alter the response to changes in brain chemistry brought about by dietary manipulation. Women who are recently menopausal (50-60 yrs. of age) and over 20 years postmenopausal (>70 yrs. of age) will take estrogen or placebo for three months. At the end of that time they will participate in three challenges using dietary techniques to briefly change the relative amounts of neurotransmitters in the brain that are believed to be related to mood regulation (serotonin, dopamine, and norepinephrine). Previous research has shown that these dietary manipulations can briefly produce negative changes in mood. The investigator hypothesizes that estrogen administration will blunt or buffer these negative effects in a quantifiable way. The investigator believes that this will provide a direct test of the ability of estrogen to meaningfully change the brain chemistry of mood in a clinically measurable and positive way. The proposed procedure will also allow assessment of the effects of estrogen on brain neurotransmitter systems after many years of very low estrogen levels.
