Use of cryo-banked oocytes in an ovum donation programme: a prospective, randomized, controlled, clinical trial
2010
background: An efficient oocyte cryopreservation method is mandatory to establish a successful egg-banking programme. Although there are increasing reports showing good clinical outcomes after oocyte cryopreservation, there is still a lack of large controlled studies evaluating the effectiveness of oocyte cryo-banking. In this study, we aimed to compare the outcome of vitrified-banked oocytes with the gold standard procedure of employing fresh oocytes. methods: A randomized, prospective, triple-blind, single-centre, parallel-group controlled-clinical trial (NCT00785993), including 600 recipients (a ¼ 0.05 and power of 80% for sample-size calculation) selected among 1032 eligible patients fr…
Sympathetic Vasomotor Response of the Radial Artery in Patients With Diabetic Foot Syndrome
2003
OBJECTIVE—Neurophysiological assessment of the peripheral autonomic system is characterized by various limitations. An alternative approach to laser Doppler and venous plethymography is the assessment of the sympathetic vasomotor response of the radial artery obtained by continuous wave Doppler sonography. Nomogram data have been established and demonstrate the temporary disappearance of diastolic flow after coughing or deep inspiration. RESEARCH DESIGN AND METHODS—We assessed the sympathetic vasomotor response in 25 patients (mean age 64 years, range 43–76) with diabetic foot syndrome. The Doppler data were correlated with nerve conduction studies of the median and peroneal nerve, the exte…
Circulating miR-200–family micro-RNAs have altered plasma levels in patients with endometriosis and vary with blood collection time
2015
Objective To determine whether circulating micro-RNA (miR) 200a, miR-200b, and miR-141 have altered levels in patients with endometriosis compared with control individuals. Design Experimental laboratory study. Setting University. Patient(s) Patients with endometriosis (n = 61), laparoscopically confirmed endometriosis-free women (n = 35), and self-reported healthy women (n = 30) were included in the study. Intervention(s) None. Main Outcome Measure(s) Plasma miRNA levels in endometriosis patients and control subjects. Result(s) We found that the levels of studied miRNAs varied with blood collection time, being lower in the morning than in the evening. When blood collection time was taken i…
Uterine effects of clomiphene citrate in women with polycystic ovary syndrome: a prospective controlled study
2006
Background Previous data on the efficacy of clomiphene citrate, the most commonly used drug for treating anovulatory infertility in patients with polycystic ovary syndrome (PCOS), have shown a discrepancy between ovulation and pregnancy rates. In the present subanalysis (of a larger previously published randomized controlled trial), the effect of clomiphene citrate on several ultrasonographic markers of uterine receptivity in PCOS patients who ovulated under treatment was studied. Methods Thirty-three PCOS women who ovulated under 150 mg daily clomiphene citrate and 33 healthy controls were studied. Uterine, subendometrial and endometrial blood flows, endometrial thickness and pattern were …
La actividad física como promotora de salud en personas mayores.
2018
Se considera que la actividad física tiene un papel fundamental en la salud de los individuos en todas las edades. Los efectos beneficiosos del ejercicio sobre la salud, tanto físicos como psicológicos de las personas constituyen un hecho cada vez más evidente y su estudio se ha abordado desde distintos campos profesionales, encontrándose entre ellos la Medicina, la Psicología y la Educación Física.La OMS destaca los efectos positivos del ejercicio físico sobre la salud y propone que forme parte de un planteamiento más amplio que podríamos definir como promoción de la salud. El objetivo de este estudio espromover la Salud a través del diseño, ejecución y evaluación de un taller de envejecim…
Arte e Idea. Francisco de Hollanda e l’estetica del Cinquecento
2004
Art and Ideas Francisco de Hollanda and Sixteenth-Century Aesthetics The historians of aesthetics who have studied the problem of ideas in art theory (from Panofsky to Baeumler and Tatarkiewicz) have overlooked Da pintura antiga, by Portuguese artist and theoretician Francisco de Hollanda (1517-1584), a text where the Platonic notion of idea enters a treatise on art for the first time. The present volume aims to fill such gap by shedding light on an author who has long been overshadowed by the great Michelangelo (whom Hollanda met during his stay in Rome in the years 1538-1540), as well as by advancing an analysis of the aesthetic concepts that emerge not only from Da pintura antiga, but fr…
Contribution of the physical, social, psychological and environmental domains to overall quality of life of the elderly
2006
Este estudo investigou a contribuição de cada domínio da qualidade de vida (físico, social, psicológico e ambiental) na qualidade de vida global e em que extensão esses domínios explicam a qualidade de vida global de idosos residentes no município de Teixeiras, na Região Sudeste do Brasil. Trata-se de um estudo observacional de corte transversal, sendo a amostragem aleatória estratificada por sexo, uso do Programa Saúde da Família e microárea de saúde (n = 211, indivíduos com idade igual ou superior a 60 anos), representando 14,28% do total de idosos do município em estudo. O instrumento utilizado foi o Word Health Organization Quality of Life Instrument Bref (WHOQOL-Bref), proposto pela Or…
Coupling between agonist and chloride ionophore sites of the GABA(A) receptor: agonist/antagonist efficacy of 4-PIOL.
2000
Eight gamma-aminobutyric acid (GABA) mimetics were tested on their ability to differentiate native GABA(A) receptor subtypes present in various rat brain regions. In rat brain cryostat sections, little regional variations by the agonistic actions of muscimol, thiomuscimol, 4,5,6,7-tetrahydroisoazolo(5,4-c)pyridin-3-ol, piperidine-4-sulphonic acid, taurine and beta-alanine on [35S]t-butylbicyclophosphorothionate ([35S]TBPS) binding to GABA(A) receptor channels were found. They were very similar to those found for GABA itself and indicated no direct correlation with single subunit distributions for any of these compounds. Only the low-efficacy GABA mimetic 5-(4-piperidyl)isoxazol-3-ol (4-PIOL…
GABA, receptor mediated fast synaptic inhibition in the rabbit brain-stem respiratory system
1991
The involvement of GABA mediated neurotransmission in the central control of respiration was investigated by administration of the specific GABAA receptor agonist muscimol and the specific GABAA receptor antagonist biculline into the fourth cerebral ventricle of the rabbit. Cycle-triggered averaging of the phrenic nerve activity (PNA) was used to quantify drug-induced changes of the central respiratory pattern. Muscimol reduced the peak amplitude of PNA and increased the duration of the respiratory phases. High amounts of muscimol led to a long-lasting but reversible central apnea. Bicuculline very effectively blocked the effects of externally applied muscimol. Blockade of intrinsically act…
GABAA agonist muscimol ameliorates learning/memory deficits in streptozocin-induced Alzheimer’s disease non-transgenic rat model
2015
Background: GABAergic inhibitory action regulates learning/memory processes and contributes to neurotransmission (Gong et al., 2009). Existing evidence suggests GABAergic system is involved in pathophysiology of Alzheimer’s disease (AD) via inhibitory interneuron deficits (Verret et al., 2012) and decrease in functional GABAA receptors (Limon et al., 2012). In vitro, GABA and muscimol (GABAA receptor agonist) blocked neuronal death induced by Aβ in rat hippocampal and cortical neurons (Paula-Lima et al., 2005). Our concept: low doses of muscimol may prevent learning/memory deficits in intracerebroventricular (icv) streptozocin (STZ)-induced AD non-transgenic rat model. Methods. Wistar male …
