This study investigated the role of cytochrome P-450 2E1 in enhanced microsomal lipid peroxidation in experimental alcoholic liver disease. We also examined the contribution of this isoform to the increased microsomal injury in alcoholic liver disease caused by carbon tetrachloride-induced or iron-induced oxidant stress. Adult male Wistar rats were(More)
STUDY DESIGN A prospective double blind cross over trial of intravenous 4-Aminopyridine (4-AP). OBJECTIVE To determine the efficacy of this drug in the treatment of spinal cord injured (SCI) patients for neurologic impairment, pain and spasticity. SETTING The post anesthesia care unit (PACU) of a tertiary care acute hospital. METHODS Twelve paraplegic(More)
The steroidogenic capacity and oxidative stress-related parameters of the human corpus luteum (CL) at different stages of the luteal phase were studied under basal and human chorionic gonadotropin (hCG)-stimulated conditions. Mid CL exhibited the maximal steroidogenic capacity, together with lower levels of glutathione and higher thiobarbituric acid(More)
BACKGROUND The relationship between leptin and insulin sensitivity, sexual steroids and insulin concentrations in women with polycystic ovary syndrome is still controversial. The objective of this study was to assess the relationship between insulin levels, insulin resistance parameters and serum leptin concentrations in healthy and polycystic ovary(More)
OBJECTIVE To determine the effects of 10~weeks of locomotor training (LT) using body weight supported (BWS) treadmill training and resistance training (RT) programs on over-ground walking recovery, walking speed and distance, functional independent measure (FIM), walking index for spinal cord injury (WISCI) and Berg Balance Score in an elderly person with(More)
The purpose of the current study was to determine the effects of three different pulse durations (200, 350, and 500 microseconds [P200, P350, and P500, respectively]) on oxygen uptake (VO2), cycling performance, and energy expenditure (EE) percentage of fatigue of the knee extensor muscle group immediately and 48 to 72 h after cycling in persons with spinal(More)
To evaluate the effect of reactive oxygen species in human corpus luteum function, we investigated whether hydrogen peroxide (H2O2) affects the in vitro luteal cell production of steroids. H2O2 treatment (1.0-100 microM) of mid and late luteal cell cultures elicited a dose-dependent decrease in basal progesterone production. However, treatment of mid luteal(More)
Elevation and maintenance of the head in an elevated, midline position reduces cerebral venous and intracranial pressure (ICP) in adult neurosurgical patients. To determine the possible effect of head position on ICP in the neonate, we studied 26 neonates less than 2500 g at birth and less than or equal to 10 days of age. ICP was measured in each of 4(More)
A total of 12 women (24.2 +/- 1.6 years old, BMI 36.7 +/- 1.5 Kg/m2) with hyperandrogenism (HA) and with normal glucose tolerance test were studied to evaluate the involvement of endogenous opioids in the pathophysiology of insulin secretion and insulin sensitivity in HA by administering naltrexone, an oral opioid receptor antagonist. Six patients received(More)
