A case of mixed connective tissue disease (MCTD) is presented in which mediastinal lymphadenopathy was the most prominent radiological finding detected by plain chest radiographs and computed tomography. Pulmonary arterial hypertension, which is a rare and often fatal complication of MCTD, also developed in this patient. 相似文献

We have recently demonstrated a remarkable selection of in vitro
cultivated, TNP-specific polyclonal T cell lines for the expression of a
TCR beta chain encoded by the V beta 8.2 gene. The goal of the present
study was to analyse V alpha usage in V beta 8.2 T cells responsive to TNP,
using TNP-specific T cell lines derived from three common strains of mice,
as well as from V beta 8.2 transgenic mice. Results indicate that in vitro
TNP stimulation of T cells from TNP- immune mice results in significant
skewing of V alpha usage among responding V beta 8.2+ T cells, with
overexpression observed for V alpha 3.2 and V alpha 8. These results
indicate that V alpha expression influences recognition of TNP by T cells,
and suggest that the hapten TNP might be recognized like typical peptide
antigens by combinatorial TCR alpha and beta contact sites.

Different dietary proteins affect whole body protein anabolism and accretion and therefore, have the potential to influence results obtained from resistance training. This study examined the effects of supplementation with two proteins, hydrolyzed whey isolate (WI) and casein (C), on strength, body composition, and plasma glutamine levels during a 10 wk, supervised resistance training program. In a double-blind protocol, 13 male, recreational bodybuilders supplemented their normal diet with either WI or C (1.5 gm/kg body wt/d) for the duration of the program. Strength was assessed by 1-RM in three exercises (barbell bench press, squat, and cable pull-down). Body composition was assessed by dual energy X-ray absorptiometry. Plasma glutamine levels were determined by the enzymatic method with spectrophotometric detection. All assessments occurred in the week before and the week following 10 wk of training. Plasma glutamine levels did not change in either supplement group following the intervention. The WI group achieved a significantly greater gain (P < 0.01) in lean mass than the C group (5.0 +/- 0.3 vs. 0.8 +/- 0.4 kg for WI and C, respectively) and a significant (P < 0.05) change in fat mass (-1.5 +/- 0.5 kg) compared to the C group (+0.2 +/- 0.3 kg). The WI group also achieved significantly greater (P < 0.05) improvements in strength compared to the C group in each assessment of strength. When the strength changes were expressed relative to body weight, the WI group still achieved significantly greater (P < 0.05) improvements in strength compared to the C group. 相似文献

The CT appearance of the adrenal glands was investigated in 30 patients with congenital renal anomalies (17 cases of unilateral renal agenesis, 11 of inferior ectopy, and 2 of crossed fused ectopy). The ipsilateral adrenal was clearly identified in 83% of these patients; in all of them, the adrenal was a paraspinal disk-shaped organ, which appeared linear on CT. Conversely, the adrenals retained their normal shape in a control group of 20 patients with acquired renal atrophy or prior simple nephrectomy. 相似文献
