CONTEXT Genistein aglycone improves bone metabolism in women. However, questions about the long-term safety of genistein on breast as well as its continued efficacy still remain. OBJECTIVE We assessed the continued safety profile of genistein aglycone on breast and endometrium and its effects on bone after 3 yr of therapy. DESIGN The parent study was a(More)
We investigated the Levetiracetam (LVT) ability to protect the brain against kainic acid (KA) induced neurotoxicity. Brain injury was induced by intraperitoneal administration of KA (10 mg/kg). Sham brain injury rats were used as controls. Animals were randomized to receive either LVT (50 mg/kg) or its vehicle (1 ml/kg) 30 min. before KA administration.(More)
Oxidative stress has been implicated in several neurodegenerative diseases affecting both neuronal and glial cells. The aim of this study was to investigate the involvement of reactive oxygen species in glutamate-evoked activation of NF-kappaB in primary astrocytes. A prolonged exposure to glutamate (24 h) caused a depletion of intracellular glutathione(More)
BACKGROUND AND AIM Recent evidence suggests that genistein aglycone may act beneficially on surrogate cardiovascular risk markers in postmenopausal women. We assessed the effects of genistein aglycone on some cardiovascular risk factors and homocysteine levels after 3-years of continued therapy in a cohort of osteopenic, postmenopausal women. METHODS AND(More)
BACKGROUND Observational studies and small trials of short duration suggest that the isoflavone phytoestrogen genistein reduces bone loss, but the evidence is not definitive. OBJECTIVE To assess the effects of genistein on bone metabolism in osteopenic postmenopausal women. DESIGN Randomized, double-blind, placebo-controlled trial. SETTING 3(More)
BACKGROUND We investigated whether electrical stimulation (STIM) of efferent vagus nerves may suppress nuclear factor (NF)-kappaB activation and the inflammatory cascade in hemorrhagic (Hem) shock. METHODS AND RESULTS Rats were subjected to bilateral cervical vagotomy (VGX) or sham surgical procedures. Hem shock was induced by intermittent withdrawing of(More)
OBJECTIVE We evaluated and compared the effects of the phytoestrogen genistein, estrogen-progestogen therapy (EPT), and placebo on hot flushes and endometrial thickness in postmenopausal women. DESIGN Ninety healthy, postmenopausal women, 47 to 57 years of age, were randomly assigned to receive for 1 year continuous EPT (n = 30; 1 mg 17beta-estradiol(More)
INTRODUCTION RANKL and its decoy receptor osteoprotegerin (OPG) constitute a complex physiological mediator system involved in the regulation of bone resorption and may be responsible for the homeostatic mechanism of normal bone remodeling. Genistein, an isoflavone representing 1-5% of total phytoestrogen content in soybean products, may positively regulate(More)
The effects of recombinant human erythropoietin (rHuEPO) in diabetes-related healing defects were investigated by using an incisional skin-wound model produced on the back of female diabetic C57BL/KsJ-m(+/+)Lept(db) mice (db(+)/db(+)) and their normoglycemic littermates (db(+/+)m). Animals were treated with rHuEPO (400 units/kg in 100 microl s.c.) or its(More)
CONTEXT Genistein, a soy isoflavone, has received wide attention over the last few years because of its potential preventive role for cardiovascular disease. OBJECTIVE Our objective was to assess the effects of genistein administration (54 mg/d) on some predictors of cardiovascular risk in osteopenic, postmenopausal women. DESIGN AND SETTING We(More)
