BACKGROUND Androgen receptor (AR) signaling and incomplete inhibition of estrogen signaling may contribute to metastatic breast cancer (MBC) resistance to a nonsteroidal aromatase inhibitor (NSAI; letrozole or anastrozole). We assessed whether combined inhibition of androgen biosynthesis with abiraterone acetate plus prednisone and estradiol synthesis with exemestane (E) may be of clinical bene...
In order to investigation of chromosomal variation in various populations of Aegilops cylindrica from northwest of Iran, the karyotype of each populations was prepared using aceto-iron-hematoxilin staining and different chromosomal characteristics were measured. The results showed that the karyotype of these populations consisted of seven pairs of metacentric, three pairs of submetacentric and ...
UNLABELLED Proper immune restoration (CD4 count >500 and normal CD4/8 ratio) is reached only by a fraction of HIV patients, despite stable viral suppression. METHODS We present a case-control study to compare HIV patients with viral suppression >1 year, according to immune restoration pattern: adequate response (AR) defined by CD4 > 500 cells/mm(3) and CD4/8 ratio >1; partial response (PR = p...
The cutting properties of tools can be greatly improved by AlCrSiN coatings. The AlCrSiN coatings with nitrogen content in the range of 28.2–56.3 at. % were prepared by varying the N2/Ar flow ratio from 1/4 to 1/1. The influence of N2/Ar flow ratio on composition, microstructure, and mechanical properties, as well as the tribological properties, of the coatings was investigated. With increasing...
background: regulatory cd4+t (treg) cells are effective in maintaining immune tolerance. objective: to investigate single nucleotide polymorphisms (snps) of transforming growth factor β-1 (tgf-β1) and forkhead box protein 3 (foxp3) genes in iranian patients with allergic rhinitis (ar). methods: variations at codons 10 and 25 of tgf-β1 and foxp3 at positions -3279 a>c and -924 a>g were evaluated...
OBJECTIVE Examining the power (ability) of classical epidemiological estimators to rate inequality in health in univariate and composite ways. METHODS Ecological study. Ratio, excess risk, attributable risk (AR) and relative difference were the estimators used for showing disparities; all of them were weighted by population size. Kappa concordance coefficient was used between weighted estimat...
After previous preliminary observations of paradoxical deletion events affecting the inactive X chromosome in melanoma, we have surveyed the X chromosome for deletions using 23 polymorphic microsatellite markers in 28 informative (female XX) metastatic melanomas. Ten tumors (36%) showed at least one loss of heterozygosity (LOH) event, and in two cases an entire chromosome showed LOH at all info...
To improve the tool (guide wire and catheter) guidance in interventional radiology, a new approach is to project 3D X-ray Angiography (3DXA) information in real time onto a fluoroscopy image ("3D Augmented Fluoroscopy" 3D AF). Recovering the acquisition geometry is a crucial step for such augmented reality application. As 3DXA and fluoroscopy images are acquired on the same vascular C-arm, a ma...
