چکیده توان بالقوه تجاری سلولازها و کاربردهای گوناگون آن ها در بسیاری از صنایع انگیزه ای قوی برای تحقیق در این زمینه طی چند دهه گذشته بوده است. با توجه به کاربردهای فراوان این آنزیم در صنایع غذایی? در این پژوهش تصمیم به جداسازی ریزسازواره های تولید کننده سلولاز از خاک درختان انار، انگور، خرمالو و گردو حیاط دانشکده کشاورزی تربیت مدرس، گرفته شد. در این بین خاک درخت خرمالو به دلیل دارا بودن تعداد ...
Wet spinning was used to manufacture fibrous alginate hydrogel wound dressings. Samples manufactured using varied operating parameters (decreased air pressure and calcium concentration or increased nozzle diameter and alginate concentration) were compared with the control samples. The changes in the fiber size, Young's modulus, swelling ratio, fetal bovine serum (BSA) release efficacy, water va...
The aim of this study was to evaluate the effect collagen shield on epithelial wound healing in rabbit eyes. Adult New Zealand Albino rabbits were used study. All surgical procedures carried out under general anesthesia. Superficial keratectomies 6 mm diameter created 40 eyes 20 and they separated into 3 groups as control (CN), medical treatment (CA) barrier (CB) groups. In CN group, received 0...
dendrimer synthesis strategies now provide virtual control of macromolecular nanostructures as a function of size and surface/interior functionality. these strategies involve the covalent assembly of hierarchical components reactive monomers , branch cells or dendron’s around atomic or molecular cores according to divergent/convergent dendrite branching principles.combinon of two or more dendri...
heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...
Introduction: Impaired wound healing in diabetic patients is a major clinical problem, which is associated with significant morbidity and mortality. Estrogen has positive effects on neoangiogenesis, reepithelialization and cell proliferation. In this research, effect of estrogen on wound healing in diabetic male rats was investigated. Methods: This study was performed on male Wistar rats (body ...
Background and Aim: Wound healing is a complex process which is divided into four overlapping phases: heamostasis, inflammation, proliferation, and remodeling. In diabetic patients, progression of healing takes longer and thus using new medication to accelerate it is required. It is expected that Prosopis farcta which has antibacterial, antidiabetic and antiinflammation effects will facilitate ...
Background and aim: Shortening of the duration of wound healing is an attractive subject for investigators in recent years. In this study, the effects of topical phenytoin, silver sulfadiazine, estrogen and their combination on wound healing were evaluated.Materials and Methods: This experimental study was accomplised on 30 male albino rats, which had an approximate wei...
Background and Aim: Wound healing is a complex and dynamic process with the wound environment changing with the changing health status of the individual. Therefore identification new natural products is necessary for accelerate wound healing. The present study investigated the effect of topical application of Persian Gulf brittle star alcoholic extract on wound healing in Balb/C mice. Materials...
Background & Objective : The Cucurbita pepo is one of plants that are functional in traditional therapy. This plant has antioxidant and skin damage repair properties. This study investigated the effect of Cucurbita pepo nano silver as a new nano-plant composition in wound repair skin in male mice. Materials & Methods: In this investigation, male albino mice were places in 8 groups, each conta...
