The tumor microenvironment (TME) greatly influences the proliferation and progression of HNSCC. Hence, an in depth understanding vivo TME is crucial recapitulating like pathophysiology vitro, still remains a challenge. 3D bioprinted models are increasingly researched on due to their ability precisely replicate cellular organization as seen vivo. This project attempts HNSCC vitro via bio printin...
این پژوهش به منظور بررسی تغییرات ترکیبات شیمیایی و ارزش غذایی سیلوی کاه کنجد با افزودن اوره، ملاس و آنزیم به روش in vitro و in situ انجام شد. بدین منظور کاه کنجد جمع آوری و جهت سیلو نمودن به قطعات 4-2 سانتی متری خرد گردید. سپس با استفاده از اوره( 5 درصد)، ملاس(10 درصد) و آنزیم ( 3 گرم به ازای هر کیلوگرم ماده خشک) قبل از سیلو مخلوط و درون سطل های 5 کیلویی پلاستیکی سیلو شدند و بعد از 45 روز باز ش...

background: infertility is an increasing medical and social problem. in vitro fertilization (ivf) has become a common and accessible treatment for a wide variety of indications that have variable outcomes. natural killer (nk) cells have been identified as relevant immunological factors involved in reproductive success or failure. objective: the aim of this study was to compare the percentage of...
background: pyridaben, a pyridazinone derivative, is a new acaricide and insecticide for control of mites and some insects such as white flies, aphids and thrips. objective: this study was designed to elucidate how pyridaben can affect the sperms' morphological parameters, its dna integrity, and to estimate the effect of various quantities of pyridaben on in vitro fertilization rate. materials ...
elicitation with middle-viscous chitosan (30 mg/50 ml) significantly stimulated silymarin synthesis in silybum marianum hairy root cultures. the root cultures established by infection with agrobacterium rhizogenes ar15834 showed a potential for production of silymarin. elicitation with medium molecular weight of chitosan (0, 5, 10, 20, and 30 mg/50 ml) was used in order to improve silymarin pro...
background: acanthamoeba keratitis (ak) is potentially a sight-threatening infection and its treatment is challenging. this is mainly due to presence of resistant cyst form. indeed, cysts are highly resistant to current available drugs. chemical drugs are toxic to human keratocytes. it should also be mentioned that most available anti- acanthamoeba drugs are poorly cysticidal, in iran and world...
in vitro maturation (ivm) is a method that immature oocytes in antral follicles are extracted and matured in laboratry conditions. this review has attempted to provide the current knowledge and recent findings in in vitro maturation of oocytes and highlights the most important factors involved in this process. the review is based on literature reports and the author’s experience. in ivm cycles,...
contact hypersensitivity (chs) mouse model induced by 2, 4-dinitrofluorobenzene (dnfb) is thought to be a t helper 1 (th1)-dominant response and used for investigating anti-inflammatory and immunosuppressive agents. however, it is hardly used for screening large-scale drugs because of the large number of animals and complex mechanisms involved in-vivo. in this study, we focused on whether t lym...
In this work, we report high biological performance of silicon substituted nano hydroxyapatite (nHA) prepared by immersion of calcium phosphate and sodium silicate as precursors in Simulated Body Fluid (SBF) solution for 24, 36, 48 and 72 hrs at 37°C. Characterization and chemical analysis of the synthesized powders were performed by Fourier transform, infrared spectroscopy (FT-IR), X-ray powde...
