some reports indicate a wide range for zn requirements for broiler chickens i.e. from 10.6 to 105 mg kg-1. a number of factors other than dietary zn concentration determine the need for supplementation, principally dietary phytate. therefore, the objective of the present investigation was reevaluation of the zinc requirement for broiler, fed practical diet supplemented with phytase in a dose-re...

Skeletal muscle loss or sarcopenia in aging has been suggested in cross-sectional studies but has not been shown in elderly subjects using appropriate measurement techniques combined with a longitudinal study design. Longitudinal skeletal muscle mass changes after age 60 yr were investigated in independently living, healthy men (n = 24) and women (n = 54; mean age 73 yr) with a mean +/- SD foll...

the objective of this study was to determine the effects of supplemented selenium (se) on plasma cortisol, red blood cell glutathione peroxidase activity (rbc gsh-px-1), concentration of immunoglobulin g (igg) and body weight in pneumonic suckling calves. ten holstein suckling male calves were randomly allocated to two groups and fed either unsupplemented milk (control) or with milk supplemente...

Data from six observational studies and three controlled trials in which calcium intake was the independent variable (and either bone mass or blood pressure the original outcome variable) have been reanalyzed to evaluate the effect of calcium intake on body weight and body fat. Analysis reveals a consistent effect of higher calcium intakes, expressed as lower body fat and/or body weight, and re...

OBJECTIVES We investigated the correlation between changes in body weight and body composition parameters. METHODS We used the data of 2635 Japanese (40.2±12.2 years) at baseline and at 1-year follow-up from a database of 13522 subjects, which is available at the Okayama Southern Institute of Health in Okayama prefecture, Japan. Body weight, waist circumference at the umbilical level, hip cir...

this work analyzes the effects of satureja khuzestanica essential oil (skeo) on the thyroid and antioxidant system, assessed by measuring levels of tri-iodothyronine (t3), thyroxine (t4), thyroid-stimulating hormone (tsh), malondialdehyde (mda), reduced glutathione (gsh), and glutathione peroxidase (gpx) activity. forty adult male sprague dawley rats (225 ± 25 g) were divided into five equal gr...

This study investigated the impact of body armor weight and load magnitude and distribution on the lower extremities during walking. Range of motion (ROM) was assessed while seven healthy, male, right-handed, military university students walked while wearing seven different garments of varying weights (0.06 kg, 9 kg, 18 kg, and 27 kg) and load distributions. Decreased pelvic rotation found with...

BACKGROUND Overt hypothyroidism and hyperthyroidism may be associated with weight gain and loss. We assessed whether variations in thyroid function within the reference (physiologic) range are associated with body weight. METHODS Framingham Offspring Study participants (n=2407) who attended 2 consecutive routine examinations, were not receiving thyroid hormone therapy, and had baseline serum ...

The effects of aqueous extract of Enantia chlorantha were studied on sperm motility, viability and counts in adult albino rats. Oral administration of 50 and 100 mg/kg body weight of the extract daily for a week caused dose-dependent changes in the sperm motility and viability without a significant change in the sperm counts. There was a significant increase in sperm motility and viability (P <...

Motivational interviewing, a directive, patient-centred counselling approach focused on exploring and resolving ambivalence, has emerged as an effective therapeutic approach within the addictions field. However, the effectiveness of motivational interviewing in weight-loss interventions is unclear. Electronic databases were systematically searched for randomized controlled trials evaluating beh...
