To assess the relationship between passive smoking and asthma, we investigated (1) whether passive smoking was more prevalent among asthmatic than control children and (2) whether exposure to tobacco smoke was higher in acute asthma than in nonacute asthma. Three groups were recruited into a case-control study: 72 acute asthmatic children from the emergency room (ER), 35 nonacute asthmatic chil...

Understanding the genetic pathways that regulate how pathogenic fungi respond to their environment is paramount to developing effective mitigation strategies against disease. Carbon catabolite repression (CCR) is a global regulatory mechanism found in a wide range of microbial organisms that ensures the preferential utilization of glucose over less favourable carbon sources, but little is known...

Abstract We analyze quantum correlations and coherence in neutrino oscillations. To this end, we exploit complete complementarity relations (CCR) that fully characterize the interplay between different encoded a system both for pure mixed states. consider CCR oscillations case of plane-waves (pure state) wave packets (mixed state). In last find complex structure depending on mixing angle, show ...

A prospective study was carried out to assay the level of serum intact parathormone and its correlation with biochemical parameters in patients with chronic renal failure (CRF). The study included 64 children (44 with CRF, and 20 age and sex matched controls). Serum intact parathormone (iPTH), serum creatinine, urea, calcium, inorganic phosphate and alkaline phosphatase were estimated. Creatini...

The presence of even mild renal insufficiency is usually associated with an increased rate of cardiovascular events after coronary stenting. The aim of this study was to evaluate the impact of mild to moderate renal insufficiency on the chronic vascular responses to the implantation of paclitaxel-eluting stents (PES; Taxus) and bare-metal stents (BMS). In the TAXUS IV, TAXUS V, and TAXUS VI tri...

Chemokines and their receptors play a critical role in the selective attraction of various subsets of leukocytes. We examined the chemokine receptor expressions and responsiveness of cord blood (CB) T cells. Flow-cytometric analysis revealed that peripheral blood (PB) T cells expressed CCR-1, CCR-2, CCR-5, CCR-6, CXC chemokine receptor-3 (CXCR-3), and CXCR-4, while CB T cells expressed only CXC...

The chemokine receptor, CCR-5, a G protein-coupled receptor (GPCR) which mediates chemotactic responses of certain leukocytes, has been shown to serve as the primary co-receptor for macrophage-tropic human immunodeficiency virus type 1 (HIV-1). Here we describe functional coupling of CCR-5 to inhibition of forskolin-stimulated cAMP formation via a pertussis toxin-sensitive G(i) protein mechanis...

Cinnamoyl-CoA reductase (CCR), an enzyme central to the lignin biosynthetic pathway, represents a promising biotechnological target to reduce lignin levels and to improve the commercial viability of lignocellulosic biomass. However, silencing of the CCR gene results in considerable flux changes of the general and monolignol-specific lignin pathways, ultimately leading to the accumulation of var...

The Coordinated Clusters Representation (CCR) is a texture descriptor based on the probability of occurrence of elementary binary patterns (texels) defined over a square window. The CCR was originally proposed for binary textures, and it was later extended to grayscale texture images through global image thresholding. The required global binarization is a critical point of the method, since thi...

Enhanced formation of reactive oxygen species (ROS), superoxide (O2*-), and hydrogen peroxide (H2O2) may result in either apoptosis or other forms of cell death. Here, we studied the mechanisms underlying activation of the apoptotic machinery by ROS. Exposure of permeabilized HepG2 cells to O2*- elicited rapid and massive cytochrome c release (CCR), whereas H2O2 failed to induce any release. Bo...
