پلی‌ساکارید هیالورونیک اسید (HA)، جزء اصلی ماتریکس خارج سلولی اپیتلیال، عصب و بافت همبند مهره داران و هم چنین کپسول خارج سلولی برخی از میکروارگانیسم‌ها است. این پلی ساکارید به علت ویژگی هایی از قبیل ویسکوزیته‌ی بالا و خاصیت زیست سازگاری، کاربردهای مختفی در زمینه‌های چشم پژشکی، ارتوپدی، آرایشی و مهندسی بافت دارد. بافت های حیوانی و استرپتوکوک‌ها سهم اصلی را در به دست آوردن هیالورونیک اسید دارند؛ ...
Increased use of vancomycin has led to the emergence of vancomycin-intermediate Staphylococcus aureus (VISA). To investigate the mechanism of VISA development, 39 methicillin-susceptible strains and 3 MRSA strains were treated with vancomycin to induce non-susceptibility, and mutations in six genes were analyzed. All the strains were treated with vancomycin in vitro for 60 days. MICs were deter...
Gold surfaces functionalized with an α-helical peptide have been generated by reacting an azide-terminated self-assembled monolayer with structured peptides containing two cyanophenylalanines through a Huisgen cycloaddition. Mixed monolayers of a reactive bromine-terminated thiol and inert alkane thiol were prepared at various concentrations of the Br-terminated moiety. These were reacted with ...
Arbuscular mycorrhizal (AM) fungi, in symbiosis with plants, facilitate acquisition of nutrients from the soil to their host. After penetration, intracellular hyphae form fine-branched structures in cortical cells termed arbuscules, representing the major site where bidirectional nutrient exchange takes place between the host plant and fungus. Transcriptional mechanisms underlying this cellular...
BACKGROUND Schizophrenia is the collective term for an exclusively clinically diagnosed, heterogeneous group of mental disorders with still obscure biological roots. Based on the assumption that valuable information about relevant genetic and environmental disease mechanisms can be obtained by association studies on patient cohorts of ≥ 1000 patients, if performed on detailed clinical datasets ...
GRAS family is one of plant specific transcription factors and plays diverse roles in the regulation of plant growth and development as well as in the plant disease resistance and abiotic stress responses. However, the investigation of GRAS family and multi-tissue gene expression profiles still remains unavailable in bamboo (Phyllostachys edulis). Here, we applied RNA-Seq analysis to monitor gl...
It has been observed experimentally that the mapping of global to detailed routing in conventional FPGA routing architecture (2D array) yields unpredictable results. In [8,10,13], a different class of FPGA structures called Greedy Routing Architectures (GRAs), where a locally optimal switch box routing can be extended to an optimal entire chip routing, were investigated. It was shown that GRAs ...
