The current study deals with a digestive α-amylase in the larvae of Pieris brassicae L. through purification, enzymatic characterization, gene expression, and in vivo effect of a specific inhibitor, Acarbose. Although α-amylase activity was the highest in the whole gut homogenate of larvae but compartmentalization of amylolytic activity showed an equal activity in posterior midgut (PM) and ante...

ette-Guérin (Mycobacterium bovis BCG) in protecting humans against tuberculosis has prompted a search for the mechanisms through which BCG induces chemokines. In this study, our experiments were designed to determine the role of the transcription factor nuclear factor-kB (NF-kB) and intracellular calcium in the production of interleukin (IL)-8, a main chemotactic factor, by human-derived monocy...

background and aims. the aim of the present study was to compare 1.3% sodium hypochlorite (naocl) in mtad (mixture of tetracycline isomer, acid, and detergent) for the removal of the smear layer and induction of canal erosion. materials and methods. 38 maxillary incisors were divided in three experimental groups of 10 and two positive and negative control groups of each 4 teeth, and prepared us...

BACKGROUND The variable efficacy of bacillus Calmette-Guérin (Mycobacterium bovis BCG) in protecting humans against tuberculosis has prompted a search for the mechanisms through which BCG induces chemokines. In this study, our experiments were designed to determine the role of the transcription factor nuclear factor-kappaB (NF-kappaB) and intracellular calcium in the production of interleukin (...

Protease and virulence of the extracellular products (ECP) of Vibrio carchariae strain EmI82KL, a causative agent of gastroenteritis in Epinephelus coioides, cultured on different media were studied. The bacteria grown on peptone agar, nutrient agar or brain heart infusion agar produced higher protease activities than that grown on tryptic soy agar (TSA) in terms of protein content. The additio...

UNLABELLED Mango (>Mangifera indica) belonging to Anacardiaceae family is a fruit that grows in tropical regions. It is considered as the King of fruits. The present work was taken up to identify a tool in identifying the mango species at the molecular level. The chloroplast trnL-F region was amplified from extracted total genomic DNA using the polymerase chain reaction (PCR) and sequenced. Seq...

Highly crystalline N and S co-doped carbon dots (NS CDs) were synthesized by a hydrothermal method using mesaconic acid, ethylenediamine, sulfuric acid as C, N, sources.

A systematic spectrofluorimetric study of the formation of ternary complexes of terbium ions (Tb3’) with ethylenediamine tetraacetic acid (EDTA) and a variety of bidentate organic ligands has been performed. Fourteen ligands (salicylic acid, quinolones and hydroxybenzene sulfonic acid derivatives) were examined as efficient energy donating chelators for Tb3+. The fluorescence properties of the ...
