tissue culture methods provide tools to supplement traditional methods for collection, propagation and preservation of endangered plant species. in this study, in vitro propagation of diaphanoptera khorasanica rech.f., a rare and threatened plant species with limited distribution range and population was investigated. this species has a potential as an ornamental plant. single node explants wer...
nucleostemin (ns), a stem cell-abundant nucleolar protein, is critical for maintaining the self-renewal and proliferative properties of normal and cancerous stem cells. recent data suggests that ns signaling is important for proliferation of t-cells and leukemia cells. this study was conducted to verify the role of ns in pathogenesis and treatment of t-cell acute lymphocytic leukemia (t-all). o...
background: based on recent studies, there are controversial reports on the ca-pacity of tissue cyst forming of toxoplasma gondii rh strain. in this study, the capac-ity was evaluated by in vivo and in vitro experiments. methods : rh strain was subcutaneously inoculated to ten wistar rats. after one month, their blood, brain, tongue and diaphragm were collected and evaluated by mat, pcr, pathol...
به منظور بررسی قابلیت مهار آفلاتوکسین b1 توسط پروبیوتیک باسیلوس، آزمایش های in vitro و in vivo انجام شد. از محتویات دستگاه گوارش 40 قطعه طیور مختلف 350 ایزوله باسیلوس جداسازی گردید. پس از انجام تست های پروبیوتیکی رایج و آزمون آفلاتوکسین زدایی بر روی جدایه ها ، یک جدایه که واجد بالاترین صفات مورد بررسی بود انتخاب و به عنوان laterosporus (bl) berevibacillus شناسایی گردید و در آزمایش مزرعه ای مورد...
Background and Aim: Recently, several studies have indicated that the central nervous system has the capacity for endogenous repair. But, the proliferation capacity of endogenous neural stem cells (NSCs) isn’t sufficient for the treatment of neurodegenerative diseases. So, it sounds that stimulation of endogenous NSC proliferation is essential for neuroregeneration. The aim of this study ...
background recent investigations show that both proliferation and secretion of macromolecules by cells can be regulated by low level laser therapy (lllt). the aim of this study was to determine whether lllt could induce a bio-stimulatory effects on human gingival fibroblasts (hgf3-pi 53). therefore, the effect of laser irradiation on human gingival cell proliferation and collagen type i gene e...
UCB-1 (Pistacia atlantica × P. integrima) is a commercial rootstock for pistachio in some pistachio plantations across the world. This rootstock is very new in Iran and recently, it has been used commercially in some plantations due to its high growth. Propagation of this rootstock by tissue culture results in many limitations such as shoot tip necrosis (STN) and a low proliferation rate. There...
Background and Aim: Previous studies have shown that some dyes used in photodynamic therapy (PDT) have a low pH and may cause root demineralization and remove the smear layer. This study aimed to assess and compare the effects of root biomodification with citric acid and PDT on the adhesion and proliferation of human gingival fibroblasts (HGFs). Materials and Methods: In this in vitro experime...
this study was conducted to determine the chemical composition, digestibility, degradability and nutritive value of madder, rubia tinctorum l. and alfalfa medicago sativa. using in vitro and in situ measurements. the mean values for om, cp, ndf, adf and ee were 892.5, 172.0, 306.5, 219.4 and 16.0 g/kg dm for madder hay, and 921.3, 141.4, 482.0, 361.1 and 6.50 g/kg dm for alfalfa hay, respectiv...
