objective: leishmaniasis is one of the six most common parasitic infections in tropical regions. there are different therapeutic modalities. however therapeutic resistance is developed and resulted in numerous problems. so evaluation of other therapeutic modalities is performed extensively. we compared the therapeutic response of cutaneous leishmaniasis with glucantime and garlic extract and it...

background: receptor for advanced glycation end products (rage) plays a causative role in diabetes. garlic (allium sativum) belongs to compounds with anti-glycation activity that can be considered as probable therapeutic approaches in delaying or preventing the onset of diabetes complications. the aim of this study was to evaluate the influence of garlic on the rage expression and proinflammato...

Background & Aims: Chronic pulmonary infection in patients with cystic fibrosis is predominantly due to infection by mucoid strains of Pseudomonas aeruginosa. Mucoid P. aeruginosa is due to the production of exopolysaccharide called also alginate. Alginate in addition to interference with the clearance of lung has antiphagocytic property. Optimal killing activity of P. aeruginosa requires opson...

Small-angle X-ray scattering (SAXS) measurements reveal a striking difference in intermolecular interactions between two short highly charged peptides-deca-arginine (R10) and deca-lysine (K10). Comparison of SAXS curves at high and low salt concentration shows that R10 self-associates, while interactions between K10 chains are purely repulsive. The self-association of R10 is stronger at lower i...

Research into antiviral agents directed at hepatitis C virus (HCV) proteins is commonly based and tested on a single genotype, namely, genotype 1. This is despite the high level of variability of the RNA virus and the frequency of infection with genotypes other than genotype 1. The systematic evolution of ligands by exponential enrichment (SELEX) is a novel in vitro approach used in this study ...

NGST is capable of reaching the main sequence turnoff of the oldest stellar populations (MV = +4.5) out to a distance ≈ 2 Mpc. There is now evidence that the oldest, most metal poor star clusters are coeval to within 1 Gyr over a 200 kpc radius centered on the Milky Way. NGST can be used to make an equally definitive test of this in the halo and globular cluster system of M31, NGC 147, 185, and...

The basal respiration rate at 10°C (R10) and the temperature sensitivity of soil respiration (Q10) are two premier parameters in predicting the instantaneous rate of soil respiration at a given temperature. However, the mechanisms underlying the spatial variations in R10 and Q10 are not quite clear. R10 and Q10 were calculated using an exponential function with measured soil respiration and soi...
