PURPOSE Biologically uncommon D-β-aspartyl (D-β-Asp) residues have been detected in proteins from various human tissues from elderly donors and are connected with cataract, age-related macular degeneration, Alzheimer disease and UV-irradiated skin. In a previous study, we prepared a highly specific antibody against the peptide Gly-Leu-D-β-Asp-Ala-Thr-Gly-Leu-D-β-Asp-Ala-Thr-Gly-Leu-D-β-Asp-Ala-...

fabms analysis of t-lb peptide before and after one cycle of edman degradation indicated an unblocked n-terminal thr residue for this tryptic peptide. in contrast , our data showed a molecular protonated ion, mh + for t- la peptide at 655 mass units (mu) which is 42 mu higher than the mh ion of t- 1b peptide. in addition, t- la peptide was not amenable to one cycle of manual edman degradation. ...

Using adult male C57BL/6 mice that express a yellow fluorescent protein transgene in their motor neurons, we induced experimental autoimmune encephalomyelitis (EAE) by immunization with myelin oligodendrocyte glycoprotein peptide 35-55 (MOG peptide) in complete Freund's adjuvant (CFA). Control mice of the same transgenic strain received CFA without MOG peptide. Early in the course of their illn...

Cheese ripening causes intense proteolysis, particularly when the cheese contains starter cultures. Several studies have shown presence of bioactive peptides in goat’s milk cheeses with antioxidant activity. Mexican goat cheeses’ peptide fractions were evaluated at different stages. Additionally, they correlated their Proteolysis was measured acid-soluble nitrogen and non-protein using reverse-...

conclusions this study showed that compared to standard drug treatment, treatment with hydrogel containing peptide had substantial antibacterial effects on s. aureus wound infections in mice. results the highest and lowest numbers of wounds were observed on day 2 in the negative and positive control groups, respectively. during the 8-day period, the positive control and hydrogel containing pept...

auto-reactive cells-mediated immune responses are responsible for the current tissue damages during autoimmunity. accordingly, functional modulation of auto-reactive cells has been a pivotal aim in many of recent studies. in the current study, we investigated the possibility for insertion of regulatory molecules onto auto-reactive cells through exosomal nano-shuttles as a novel approach for phe...

basic research on the autoimmune disease multiple sclerosis has been performed mainly on its animal model namely experimental allergic encephalomyelitis. there are many different approaches established to get this model. despite the existence of many references in literature in this regard, we have been faced with many difficulties generating the model suitable for studying different therapies....

In this study, the longitudinal and hoop tensile strengths of an industrial ±55° Glass Reinforced Epoxy (GRE) pipe with eighteen layers as well as the associated failure mechanisms are determined. To obtain the longitudinal and hoop tensile strengths values, three specimens are cut from the studied GRE pipe in each direction. A comparison is done between both the strength values, and the fractu...
