Glucocorticoids and colostrum feeding influence postnatal maturation of the somatotropic axis. We have tested the hypothesis that dexamethasone (Dexa) affects the somatotropic axis in neonatal calves dependent on colostrum intake. Calves were fed either with colostrum or with a milk-based formula (n = 14/group), and, in each feeding group, one-half of the calves were treated with Dexa (30 micro...

BACKGROUND Nutritional alterations are highly prevalent among patients with chronic kidney diseases stage 5 who receive haemodialysis therapy. Body composition alterations are directly related to an increased morbidity and mortality. Nutritional assessment represents a cardinal intervention oriented to improve the outcome and survival in chronic renal patients. OBJECTIVE To evaluate body comp...

Although there is growing interest in studying muscle distribution, regional skeletal muscle (SM) mass measurement methods remain limited. The aim of the present study was to develop a new dual-energy X-ray absorptiometry (DEXA) model for estimating regional adipose tissue-free skeletal muscle mass (AT-free SM). Relationships were derived from Reference Man data between tissue-system- level com...

The body adiposity index (BAI) is a recent anthropometric measure proven to be valid in predicting body fat percentage (BF%) in some populations. However, the results have been inconsistent across populations. This study was designed to verify the validity of BAI in predicting BF% in a sample of overweight/obese adults, using dual-energy X-ray absorptiometry (DEXA) as the reference method. A cr...

The acquisition of soft tissue measurements, fat (chemical) or adipose tissue (morphological) quantitics, is essential in clinical research and nutritional status and its associated health risks, This has led to a proliferation of methods for the in-vivo deterrnination of body composition, None of the indirect in-vivo approaches to estimate body adipose tissue has been validated against direct ...

Things have been changing increasingly since the first DEXA events due to the new challenges posed by new issues ubiquitously appearing in modern application domains nowadays. In this paper, a quick review of contributions to the DEXA international conferences will be given. The different research trends and challenges that have been posed are succinctly analysed. Some predictions about the fut...

The authors have performed a retrospective study of 8 patients, all elderly females, seen in the period 2002-2004 with insufficiency fractures of the tibial plateau. Their mean age was 74 years (range 70-84). There was a history of trivial trauma in all patients, except one. Three of the patients were referred to the orthopaedic department, as a fracture line was visible on the plain radiograph...

This study compared body composition by dual-energy X-ray absorptiometry (DEXA; Lunar DPX-L) with that via a four-compartment (4C; water, bone mineral mass, fat, and residual) model. Relative body fat was determined for 152 healthy adults [30.0 +/- 11.1 (SD) yr; 75.10 +/- 14.88 kg; 176.3 +/- 8.7 cm] aged from 18 to 59 yr. The 4C approach [20.7% body fat (%BF)] resulted in a significantly (P < 0...

= Abstract = Vascular proliferative lesion is one of the most important causes of stenosis and late thrombosis in arterial reconstructions. We studied the effect of cyclosporine and dexamethasone on decreasing the hyperplastic response after experimental arterial injury in rats. Ninety female rats were assigned to one of four groups, each receiving daily subcutaneous injections of either (1) sa...
