8-Isoprostane levels in serum and bronchoalveolar lavage in idiopathic pulmonary fibrosis and sarcoidosis
(2013)Objective and design: Sarcoidosis and idiopathic pulmonary fibrosis (IPF) are both associated with deregulated inflammatory mechanisms partially triggered by aggravated oxidative stress. 8-Isoprostane has been proposed as ... -
Anesthetic Ketamine Impairs Rats' Recall of Previous Information The Nitric Oxide Synthase Inhibitor N-nitro-L-arginine Methylester Antagonizes This Ketamine-induced Recognition Memory Deficit
(2011)Background: There is poor experimental evidence concerning the effects of anesthetic doses of the noncompetitive N-methyl-D-aspartate receptor antagonist ketamine on rodents' memory abilities. The current study was designed ... -
Circulating endothelin-3 and prolactin concentrations in healthy lactating women during the early puerperium
(1998)Objective: To study the association between the circulating concentrations of endothelin-3 and prolactin in the early puerperium. Design: Prospective clinical study, including twenty-five healthy puerperal women breast-feeding ... -
Correlation of Urinary Excretion of Sodium With Severity of Sleep-Disordered Breathing in Children: A Preliminary Study
(2010)Background: Nocturnal urinary sodium excretion is related to blood pressure (BP) levels. Elevated BP and increased nocturnal natriuresis have been demonstrated in adults with sleep apnea. Although evidence indicates increased ... -
Effect of an OT antagonist on the control of the midcycle LH surge in women
(2009)P>Objective Data in women regarding the role of OT in LH secretion during the LH surge are conflicting. As in previous studies blood samples for LH measurements were taken infrequently, we re-examined this matter in women ... -
Effect of ghrelin on gonadotrophin secretion in women during the menstrual cycle
(2009)It has been suggested that ghrelin may affect reproduction in animals by decreasing pituitary LH secretion. The role of ghrelin on LH secretion in women has not been investigated. Our aim was to assess the effect of ghrelin ... -
Effects of the Nitric Oxide Synthase Inhibitor L-NAME on Recognition and Spatial Memory Deficits Produced by Different NMDA Receptor Antagonists in the Rat
(2010)There is consistent experimental evidence that noncompetitive antagonists of the N-methyl-D-aspartate (NMDA) receptor, such as ketamine, MK-801, and phencyclidine (PCP), impair cognition and produce psychotomimetic effects ... -
Endothelin-3 and PRL levels in the maternal and fetal circulation at delivery
(2007)Objective: The aim of the present cross-sectional study was to test the hypothesis that endothelin-3 (ET-3) is involved in PRL secretion via systemic hormonal interaction during labor. Materials and methods: Fifty healthy ... -
Growth hormone and prolactin response to ghrelin during the normal menstrual cycle
(2009)Objective It has been suggested that exogenous oestradiol augments ghrelin-induced growth hormone (GH) secretion in postmenopausal women. Whether endogenous oestrogens exert a similar effect during the normal menstrual ... -
Induction of ovulation and spawning in the Mediterranean red porgy, Pagrus pagrus, by controlled delivery and acute injection of GnRHa
(2005)Gonadotropin-releasing hormone analogue (GnRHa) in the form of saline injections or sustained-release microspheres was used to induce oocyte maturation, ovulation, and spawning in captive red porgy (Pagrus pagrus). ... -
The metabotropic glutamate 2/3 receptor antagonist LY341495 differentially affects recognition memory in rats
(2012)Experimental evidence suggests that metabotropic glutamate 2/3 (mGlu2/3) receptor antagonists affect cognitive function, although contradictory findings have been reported. To clarify the role of mGlu2/3 receptor antagonists ... -
Molsidomine antagonizes L-NAME-induced acquisition deficits in a recognition memory task in the rat
(2003)The present study was designed to investigate the role of nitric oxide (NO) on the acquisition of a recognition memory, task in the rat. For this purpose, the effects on memory exerted by pre-training administration of the ... -
The nitric oxide (NO) donor molsidomine antagonizes scopolamine and L-NAME-induced performance deficits in a spatial memory task in the rat
(2009)Nitric oxide (NO) is considered as an intracellular messenger in the brain. Its involvement in learning and memory processes has been proposed. Compounds that inhibit NO synthase (NOS), the key synthesizing enzyme, may ... -
Oestradiol stimulates prolactin secretion in women through oestrogen receptors
(2006)Objective To examine the effects of clomiphene and raloxifene on basal and GnRH-induced prolactin (PRL) secretion in postmenopausal women. Design Postmenopausal women participated in two experimental procedures a month ... -
Oxidative stress responses in older men during endurance training and detraining
(2004)Purpose: Aging is associated with increased oxidative stress, whereas systematic exercise training has been shown to improve quality of life and functional performance of the aged. This study aimed to evaluate responses ... -
Plasma endothelin-1 in hemodialysis treatment - the influence of hypertension
(2004)In patients on chronic hemodialysis hypotensive episodes are frequently encountered during the course of treatment and the prevalence of atherosclerosis is increased. Endothelin-1 (ET-1), an endothelium-derived peptide ... -
Pre-training administration of anesthetic ketamine differentially affects rats' spatial and non-spatial recognition memory
(2009)There is poor experimental evidence concerning the effects of anesthetic doses of the non-competitive NMDA receptor antagonist ketamine on rodents' memory abilities. The present study was designed to investigate a) the ... -
Rapid effect of progesterone on transepithelial resistance of human fetal membranes: Evidence for non-genomic action
(2008)1. The factors that regulate human fetal membrane transport mechanisms are unknown. The aim of the present study was to investigate the effect of progesterone on transepithelial electrical resistance (R-TE) in the human ... -
Role of the S100B serum biomarker in the treatment of children suffering from mild traumatic brain injury
(2010)Object. The aim of this study was to provide a systematic update of the current literature regarding the clinical role of the S100B serum biomarker in the initial evaluation of children who have sustained a mild traumatic ...
