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...

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...

Introduction: Systemic corticosteroids are anti-inflammatory agents with dexamethasone among the most potent in the class. Within (respiratory) allergy, systemic corticosteroids are usually applied in medical emergencies. In these situations, patients may experience physical or logistic problems taking tablets. To fulfil a practical unmet need for outpatients, Dexa ODF, an oral dissolvable film...

Validated methods of determining murine body composition are required for studies of obesity in mice. Dual-energy X-ray absorptiometry (DEXA) provides a noninvasive approach to assess body fat and lean tissue contents. Similar to DEXA analyses in other species, body fat measurements in mice show acceptable precision but suffer from poor accuracy. Because fat and lean tissues each contain variou...

The accuracy of total body fat mass and leg fat mass measurements by fan-beam dual-energy X-ray absorptiometry (DEXA) was assessed in 60 healthy elderly subjects (aged 70-79 yr). Total fat and leg fat mass at four leg regions (total leg, thigh, midthigh, and calf) were measured with the QDR 4500A (Hologic, Waltham, MA). The four-compartment model and multislice computed tomography scans were se...

Purpose: This study was conducted to evaluate the validity of the BODPOD air displacement plethysmography as compared to the DEXA (dual energy x-ray absorptiometry) in testing body fat percentages in female collegiate runners. The link between caloric intake and body fat distribution, as well as the link between calcium and vitamin D intake and bone density was also evaluated. Methods: Particip...

CONTEXT For athletes in disciplines with weight categories, it is important to assess body composition and weight fluctuations. OBJECTIVE To evaluate the accuracy of measuring body fat percentage with a portable ultrasound device possessing high accuracy and reliability versus fan-beam, dual-energy X-ray absorptiometry (DEXA). DESIGN Cross-validation study. SETTING Research laboratory. ...
