Steroid hormone levels and bone mineral density in women over 65 years of age
Nunes, Elsa; Gallardo, Eugenia; Nunes, Sara; Moutinho, José FonsecaPrevious studies using immunoassays for steroid measurements have focused on the association between steroid hormone levels and bone mineral density (BMD) in postmenopausal women, obtaining contradictory results. This study aimed to assess this association using a highly sensitive bioanalytical method. A total of 68 postmenopausal women, aged 65–89 years, were enrolled in a crosssectional study. Measurements of...
Steroid hormone levels in postmenopausal hysterectomised women with and without...
Nunes, Elsa; Gallardo, Eugenia; Nunes, Sara; Moutinho, José FonsecaThis study aims to clarify the effect of postmenopausal bilateral oophorectomy on plasma steroid hormone levels. Women who were submitted in the postmenopausal period to hysterectomy for uterine benign conditions were divided into two groups: 18 women had isolated hysterectomy and 11 had hysterectomy with bilateral salpingo-oophorectomy. In both groups serum hormone levels were quantified by solid phase extract...
"MitoTea": Geranium robertianum L. decoctions decrease blood glucose levels and...
Santos, Maria Sancha; Seiça, Raquel; Sena, Cristina; Nunes, Elsa; Peixoto, Francisco; Ferreira, Fernanda M.Several chemical compounds found in plant products have proven to possess beneficial properties, being currently pointed out due to their pharmacological potential in type 2 diabetes mellitus complications. In this context, we studied the effect of Geranium robertianum L. (herb Robert) leaf decoctions in Goto–Kakizaki (GK) rats, a model of type 2 diabetes. Our results showed that oral administration of G. rober...
Cork oak (Quercus suber L.) wood growth and vessel characteristics variations i...
Leal, Sofia; Nunes, Elsa; Pereira, HelenaVariations in tree ring growth of Quercus suber L. were analysed using dendrochronological techniques on cork oak discs from trees harvested in the cork producing region of Alentejo, Portugal. A tree-ring chronology containing a strong common signal and covering the period from 1970 to 1995 was build for ca. 30-year-old cork oaks never submitted to cork harvesting using 14 trees that crossdated satisfactorily o...
Estradiol affects liver mitochondrial function in ovariectomized and tamoxifen-...
Moreira, Paula I.; Custódio, José B.A.; Nunes, Elsa; Moreno, António; Seiça, Raquel; Oliveira, Catarina R.; Santos, Maria S.Given the tremendous importance of mitochondria to basic cellular functions as well as the critical role of mitochondrial impairment in a vast number of disorders, a compelling question is whether 17[beta]-estradiol (E2) modulates mitochondrial function. To answer this question we exposed isolated liver mitochondria to E2. Three groups of rat females were used: control, ovariectomized and ovariectomized treated...
