The mean FMD was 3.8 +/- 2.4%. Decreasing 25 hydroxy vitamin D levels were associated with decreasing FMD [r = 0.44, p = 0.001]. In multivariate analysis the association remained independent after adjustment with traditional risk factors (adjusted beta 0.451; t = 3.46; p < 0.002).\n\nPatients with low vitamin D (<= 37.5 nmol/L) demonstrated low FMD compared to patients with vitamin D values > 37.5 nmol/L (4.4 +/- 2.5% vs. 2.5 +/- 1.6%; p = 0.007); however the traditional risk factors were similar between the two groups.\n\nConclusion: This is the first demonstration of an association of vitamin D deficiency with abnormal vascular endothelial

function in non-dialysis CKD patients. Further studies with intervention and exploration of the mechanism are

“We studied the histologic and stereological changes induced in the right ovary of newly hatched chicks treated with LH during their embryonic development. Results indicate that LH administration causes a diminution in size and total volume (P < 0.01) of the right ovary, as well as a decrease in the total volume of lacunar channels, blood vessels, and interstitium. Other changes obtained after LH treatment were a reduction (P < 0.001) in the number of germ cells, as well as an increase in the total volume of interstitial cell cords (P < 0.01). This expansion is due to the increase of cellular volume of interstitial cells (P < 0.001) and not Cl-amidine in vivo selleck products to their number, which decrease in the LH-treated right ovary. All these modifications were similar to those occurring in the regressing right ovary during development. The

findings suggest that the right ovary of the newly hatched chick is able to respond to LH treatment during embryonic development, inducing marked histologic changes that accelerate its regression. (c) 2012 Elsevier Inc. All rights reserved.”
“The source of acquisition of Pseudomonas aeruginosa in cystic fibrosis (CF) patients remains unknown. Patient-to-patient transmission has been well documented but the role of the environment as a source of initial infection is as yet unclear.\n\nIn the present study, the origin of the first P. aeruginosa isolate in CF patients was investigated by comparing the P. aeruginosa genotype(s) from newly infected patients with genotypes of P. aeruginosa isolates from the home environment and from other patients from the same CF centre.\n\nA total of 50 newly infected patients were studied. P. aeruginosa could be cultured from 5.9% of the environmental samples, corresponding to 18 patients. For nine of these, the genotype of the environmental P. aeruginosa isolate was identical to the patient’s isolate. In total, 72% of the environmental P. aeruginosa isolates were encountered in the bathroom.
