introduction : the innate immune system as the first line of defense against the pathogens recognizes pathogen-associated molecular patterns (pamps) by toll-like receptors (tlrs). interaction of bacterial pamps by tlrs results in activation of innate and acquired immunity. fimh adhesin, a minor component of type 1 fimbriae encoded by uropathogenic escherichia coli (upec) is a pamp of tlr4 that ...

introduction: glycoconjugates are molecules with a carbohydrate bounded to proteins. the terminal sugars of glycoconjugates are specific identified by lectins. glycoconjugates play an important role in various developmental processes. this study examines the developmental changes in certain glycoconjugates during the development of meckel's cartilage through lectin histochemistry. materials and...

abstract this research was conducted in toroq experimental field station, mashhad, iran, for two successive cropping seasons (2000-2002), using split plot experimental design based on complete randomized blocks with three replications. moisture stress treatments (at seven levels) were assigned to main plots, including: d1 ( full irrigation), d2 (no irrigation from one-leaf to double ridge) stag...

in this study an ultra-broad band, low-power, and high-gain cmos distributed amplifier (cmos-da) utilizing a new gain-cell based on the inductively peaking cascaded structure is presented. it is created bycascading of inductively coupled common-source (cs) stage and regulated cascode configuration (rgc).the proposed three-stage da is simulated in 0.13 μm cmos process. it achieves flat and high ...

In a yeast two-hybrid screen using the Drosophila Axin protein as a bait, we have identified a Drosophila homolog of CAP, a component of the glucose transport regulatory complex. Through alternative splicing, the DCAP gene generates a set of five different proteins with unique N-terminal sequences and a common C-terminal SH3 domain. DCAP is predominantly expressed in the midgut and fat bodies o...

GOAL the purpose of the current study was to estimate the predictive values of optical coherence tomography parameters in early, developed perimetric and terminal glaucoma. METHODS 180 eyes of 120 consecutive patients were evaluated in this retrospective cross sectional pilot study. Copernicus Spectral -domain optical coherence tomography with resolution of 3 mm obtained throught the optic ne...

Lung transplantation has been available as a therapeutic option for patients with end-stage cystic fibrosis lung disease for over 15 years, but the outcome following transplantation remains poor, and the supply of organs limited. For this reason some children opt to continue with medical treatment followed by terminal care rather than undergo transplantation. This article summarizes the current...

in our previous study, we compared the two α-amylase enzymes from bacillus sp.kr8104, bka∆(n44) and bka∆(n44c193) which is the secreted form of it. the results indicated that the presence of 193 amino acids propeptide in the c-terminal of bka∆(n44) changed its enzymatic parameters like an uncompetitive inhibitor in comparison to bka∆(n44c193). in the present study, we cloned the dna sequence of...

in order to design and manufacturing some postharvest equipment, determination of some hydrodynamic properties of crops are necessary. the quality of products in global and local markets can be increased by applying these properties and receive economical benefits. for these purpose, two local varieties of apples in the east azerbaijan province, iran(asheghi and gare yapraq)were selected.ashegh...
