in this study, silver nanoparticles were synthesized by chemical reduction method at different concentrations of ag colloid in the range of 500-16000 ppm. nanoparticles were deposited by spin coating method on pre-etched glass and si substrates. structural, optical and electrical properties of the samples were studied using scanning electron microscopy equipped with edax, uv-vis spectrophotomet...

Tamoxifen is the drug of choice as hormonal therapy for hormone receptor-positive breast cancers and can reduce risk cancer recurrence. However, oral tamoxifen has a low bioavailability due to liver intestinal metabolic passes. To overcome this problem utilize potential its maximum, inorganic nanoparticle carriers have been exploited tested increase bioavailability. Biocompatibility unique magn...

Silver nanocomposites (Ag NCs) were prepared by two methods, chemical and physical synthesis using sodium borohydride gamma irradiation as a reducing tool. A one-step silver/kaolinite nanocomposite (Ag/Kln method has been developed successfully technique at room temperature under ambient pressure. The Ag/Kln NCs produced the ?-irradiation is pure without residues, good distribution with enhance...

Abstract Chitosan is a polysaccharides compound derived from nature and has an amine group hydroxyl that gives it unique physicochemical properties, which are polychationic chelating agent. This shows chitosan can be used as stabilizer reducer of Ag nanoparticles. Unlike other studies, was in this study Black Soldier Fly exuviae been through demineralization, deproteination, depigmentation, dea...

AIM The inhibition of advanced glycation end products (AGEs) and the receptor for AGEs (RAGE) mediated downstream signaling pathways have been suggested to have retinoprotective actions in diabetic retinopathy. Herein, we examined the protective effects of aminoguanidine (AG), an AGEs inhibitor, on diabetes-induced injury of retinal ganglion cells in the Zucker diabetic fatty (ZDF) rats. MATE...

Comparative biophysical and biochemical analyses were performed on purified preparations of hepatitis B antigen (HBs Ag) subtypes adw and ayw, including isoelectric pH evaluations, analysis of the different morphological forms, molecular weight determinations, and analysis of the polypeptides by polyacrylamide gel electrophoresis, Both HBs Ag-positive plasma and purified HBs Ag were analyzed by...

N-Heterocyclic carbene-based silver complexes (Ag-NHCs) have been widely used as organometallic drug candidates in medicinal and pharmaceutical chemistry research due to their low toxicity. Due the success of Ag-NHCs biological applications, interest synthesis applications such compounds is increasing rapidly. Therefore, this study, ten Ag-NHC containing benzimidazol-2-ylidene ligand were synth...

Despite their critical role in long-term immunity, the life span of individual memory B cells remains poorly defined. Using a tetracycline-regulated pulse-chase system, we measured population turnover rates and individual t1/2 of pre-established Ag-induced Ig class-switched and IgM-positive memory B cells over 402 d. Our results indicate that, once established, both IgG-positive and less freque...

BCR editing in the bone marrow contributes to B cell tolerance by orchestrating secondary Ig rearrangements in self-reactive B cells. We have recently shown that loss of the BCR or a pharmacologic blockade of BCR proximal signaling pathways results in a global "back-differentiation" response in which immature B cells down-regulate genes important for the mature B cell program and up-regulate ge...
