Recent evidence suggests that tau aggregates are not only neurotoxic, but also propagate in neurons acting as a seed for native tau aggregation. Prion-like tau transmission is now considered as an important pathogenic mechanism driving the progression of tau pathology in the brain. However, prion-like tau species have not been clearly characterized. To identify infectious tau conformers, here w...
A new class of polymer stabilized gadolinium trifluoride nanoparticles (NPs) have been developed as contrast agents for magnetic resonance imaging (MRI) and computed tomography (CT), with potential long term goals in targeted imaging and anti-cancer therapy. The NPs are comprised of a 90/10 mixture of GdF3/EuF3 and are coated with linear polyacrylic acid (PAA) chains consisting of 25 repeating ...
Self-associated protein aggregates or cross-linked protein conjugates are, in general, more immunogenic than oligomeric or monomeric forms. In particular, the immunogenicity in mice of a recombinant malaria transmission blocking vaccine candidate, the ookinete specific Plasmodium falciparum 25 kDa protein (Pfs25), was increased more than 1000-fold when evaluated as a chemical cross-linked prote...
Diffusion of aqueous sodium dodecyl sulfate (SDS) across cross-linked polyacrylamide hydrogel membranes has been studied by electrical conductivity measurements. Initial rapid sorption of SDS (as unimer) into the membranes is observed. The effect of SDS concentration, and of cross-linker fraction on the degree of swelling of the gels is studied and associated with binding of the surfactant to t...
Cross-linking reagents have been used to link covalently adjacent subunits of solubilized spinach chloroplast coupling factor 1, which is a latent ATPase. 1,5-Difluoro-2,4-dinitrobenzene, dimethyl-3,3'-dithiobispropionimidate, and dimethylsuberimidate are able to form bridges of 3 to 11 A between amino groups, and hydrogen peroxide and the o-phenanthroline-cupric ion complex catalyze the oxidat...
آلژینات تولید شده توسط سویه های موکوئیدی pseudomonas aeruginosa ، از عوامل مهم ایجاد عفونت های مزمن ریوی در بیماران مبتلا به فیبروز سیستیک ، می باشد. آلژینات پلی ساکارید خارج سلولی و متشکل از واحدهای d- مانورونیک اسید و l-گلورونیک اسید است. پاسخ ایمنی محافظت کننده نقش مهمی در کنترل این عفونت ها دارد . از طرفی مطالعات قبلی نشان داده که عصاره سیر وفراکشن ایمونومدولاتورجدا شده از آن ، قادر به تحری...
background: nowadays, chlamydia trachomatis is known as a causative agent of infertility. because of, asymptomatic nature of infection, many may suffer from its lasting complications such as infertility. this study was performed in tehran during april 2007 to april 2008 to compare the prevalence of chlamydia trachomatis infection in fertile and infertile women using elisa and pcr methods. metho...
