OBJECTIVE To determine bone mineral density (BMD) using the posteroanterior L2-L4 (PA) and lateral L3 (LAT-L3) projections of dual energy x-ray absorptiometry (DEXA) in patients with ankylosing spondylitis (AS), and to evaluate the relationship between BMD and the presence of syndesmophytes. METHODS Twenty men with AS were studied. BMD was measured by femoral neck DEXA, PA DEXA, and LAT-L3 DE...

Children and adults with the most aggressive form of brain cancer, malignant gliomas or glioblastoma, often develop cerebral edema as a life-threatening complication. This complication is routinely treated with dexamethasone (DEXA), a steroidal anti-inflammatory drug with pleiotropic action profile. Here we show that dexamethasone reduces murine and rodent glioma tumor growth in a concentration...

Objectives: To evaluate BMD in lumbar spine of the same subjects under similar conditions both by QCT and DEXA scanners on the same day and to compare their findings in evaluating these subjects as osteoporotic, osteopenic or normal. Materials and Methods: In this cross sectional study a population of 165 subjects both male and female which included 37 young healthy volunteers, 46 post menopaus...

Appropriate insulin secretion depends on beta-cell mass that is determined by the balance between cell proliferation and death. IGF-1 stimulates proliferation and protects against apoptosis. In contrast, glucocorticoids promote cell death. In this study we examined molecular interactions of the glucocorticoid dexamethasone (dexa) with IGF-1 signalling pathways in insulin secreting INS-1 cells. ...

BACKGROUND Skinfold thickness (SFT) and bioelectrical impedance (BIA) are readily available and commonly used techniques in patient monitoring for body composition analysis (BCA) in clinical practise. Another one, dual-energy X-ray absorptiometry (DEXA) method became popular in body composition analysis (BCA) in recent years. Its results have been reported to be quite accurate and precise, in c...

Dual-energy X-ray absorptiometry (DEXA) is reported to be inferior to computed tomography (CT) to measure changes in appendicular soft tissue composition. We compared CT- and DEXA-measured thigh muscle and fat mass to evaluate the random and systematic discrepancies between these two methods. Thigh skeletal muscle area (single-slice CT) was suboptimally (r(2) = 0.74, P < 0.0001) related to DEXA...

Glucocorticoids (GCs), which act on stress pathways, are well-established in the co-treatment of different kinds of tumors; however, the underlying mechanisms by which GCs act are not yet well elucidated. As such, this work investigates the role of glucocorticoids, specifically dexamethasone (DEXA), in the processes referred to as DNA damage and DNA damage response (DDR), establishing a new app...

The present study aims to investigate if Cimicifuga racemosa (L.) Nutt extract (CIMI) reduces deleterious effects of dexamethasone (DEXA) in ovaries cultured vitro. Mouse were collected and DMEM+ only or supplemented with 5 ng/mL CIMI, 4 DEXA, both CIMI DEXA. at 37.5°C 5% CO2 for 6 days. Ovarian morphology, follicular ultrastructure, the levels mRNA Bax, Bcl-2, Caspase-3 evaluated. results show...

PURPOSE The purpose of this investigation was to compare a practical measurement of fat free mass index (FFMI) from bioelectrical impedance analysis (BIA) to the dual energy X-ray absorptiometry (DEXA) value in collegiate athletes. METHODS Thirty-three male baseball players and 16 female gymnasts volunteered to participate in this study during their respective pre-season. Subjects visited the...

The measurement of body composition is of value in the nutritional assessment of patients with chronic obstructive pulmonary disease (COPD). The purpose of the present study was to compare two bedside methods for the measurement of body composition using dual energy X-ray absorptiometry (DEXA) as a reference method. Fat-free mass (FFM) was measured using DEXA, bioelectric impedance analysis (BI...
