Hyperlipidemia is a known risk factor for fatty infiltration of the liver, a condition that can progress to cirrhosis and liver failure. The objectives of this study were to document the prevalence of fatty infiltration in the livers of hyperlipidemic patients and to identify the predictor variables associated with this condition. Over an 18-month(More)
Plasma levels of total 3-methoxy-4-hydroxyphenylglycol (MHPG) were measured in a group of 104 hospitalized depressed patients and a group of 104 age- and sex-matched normal controls. Plasma MHPG levels were found to be normally distributed in both groups and significantly lower in depressives than in controls. However, this difference could be related to an(More)
Mice were used as a model system to correlate loading, changes in cortical and trabecular bone growth and remodeling, and differences in breaking strength of the whole femur. BALB/c mice were raised for 30 days, starting at day 14, under three conditions of loading or exercise: (a) normal exercise control (NE), (b) 4 x normal gravity for a total of one(More)
BALB/c mice were raised for 30 days under nine treatment regimens to determine their effects on sexual dimorphism for size of the femur and of the body. Treatment groups were divided into three experiments: 1) burrowing in a high litter cage; eight times normal gravity for a total of one hour per day; a voluntary exercise control. 2) Unilateral femoral and(More)
This study was aimed at assessing monoamine catabolites plasma levels in depressed patients and healthy volunteers. Plasma levels of 3-methoxy-4-hydroxyphenylglycol (MHPG), homovanillic acid (HVA), and 5-hydroxyindoleacetic acid (5-HIAA) of 21 control subjects and 26 depressed patients (according to DSM III-R criteria) were measured at baseline (day 0) and(More)
Based on the hypocatecholaminergic hypothesis in the depressive syndromes, this survey on 30 depressed patients compared to 21 control patients, attempts to state exactly the potential interactions between the noradrenergic system and the hypothalamic-pituitary-adrenal and hypothalamic-pituitary-thyroid neuroendocrine axis. The biological indices used(More)
Juvenile BALB/c mice were used as a model system to test the effects of various loading and exercise regimens on the growth and development of femora. Six treatments and three controls were used to document changes in geometric, mechanical, and material properties of the femora associated with strength. In each age-matched experiment, body weight and the(More)
Using Langers' method (10) under their laboratory conditions, the authors determined the characteristics of the high-affinity imipramine-binding site on human platelets in thirty-five normal subjects, equally divided between the sexes and distributed by decade from twenty to sixty years of age and above. Bmax was 440 +/- 121 fmol./mg. protein, Kd 0.96 +/-(More)
BACKGROUND Patients with schizophrenia display significant working memory and executive deficits. In patients with obsessive-compulsive disorder (OCD), several studies suggest that working memory dysfunction may be one of the causes of compulsive checking behaviors. Hence, this study aimed at assessing whether patients with schizophrenia were impaired on an(More)
