گیاهان تیره عناب (Rhamnaceae) بهصورت درخت یا درختچه شامل 50 جنس و 600 گونه هستند که بیشتر در اروپا و نواحی استوایی میرویند. میوههای عناب دارای خواص دارویی فراوانی میباشند. در این تحقیق اثر شرایط ضدعفونی، محیط کشت و تیمارهای مختلف هورمونی روی میزان آلودگی، باززایی، پرآوری و ریشهزایی عناب مطالعه شد. از جوانههای انتهایی و جانبی شاخههای تهیه شده از درختچههای عناب بهعنوان ریزنمونه استفاد...
the present research was carried out to evaluate the response of seven selected persian leek accessions to in vitro gynogenesis. the experimental design was a factorial one based upon a completely randomized design of three culture media treatments b2d0 (2 mgl-1 ba), b2d2 (2 mgl-1 ba and 2 mgl-1 2, 4-d), and b2d4 (2 mgl-1 ba and 4 mgl-1 2, 4-d) along with seven persian leek accessions (gorgan, ...
dog rose (rosa canina l.) is one of the most important ornamental and medicinal plants which are used as a rootstock for ornamental roses such as rosa hybrid and rosa floribunda. in vitro propagation of rose has a very important role in rapid multiplication of species with desirable traits and in production of healthy and disease-free plants. micropropagation of rosa canina l. was revised, usin...
جنس سودوآلتروموناس یک گروه باکتری دریایی متعلق به کلاس گاماپروتئوباکتریا می باشد. این باکتری به علت تولید محصولات طبیعی و اکولوژی میکروبی در دهه گذشته توجه را به خود جلب کرده است. سودوآلتروموناس پیسسیدیا pg01, pg02، دو باکتری هستند، که در سال 1388 توسط داراب پور و همکاران از خلیج فارس جدا شد. بر اساس مطالعات، ترکیب استخراجی از این دو باکتری در محیط in-vitro واجد خاصیت ضدباکتریایی علیه برخی گونه...
this study concerns about quantum chemical modeling behavior of 02 on cr (100)surface by using density functional theory (dft) by lanl2dz and 6 — 31g* basissets, we presented the results of our first principles electronic structure calculationson the 02 molecules and their interface with cr (100) surface. the chromium metalhas the body-centered cubic structure, and chromium cluster has five cr ...
The present study was carried out to evaluate the effects of light and plant growth regulators on callus induction and explant browning in date palm cultivar, Estameran in in vitro condition. The explants were pretreated by an antioxidant combination (100 mgl-1 citric acid and 150 mgl-1 ascorbic acid) for 3 days in 5 °C. Then, the leaf explants were cultured in Murashige and Skoog medium (MS)...
In the present study, an efficient protocol has been developed for callus induction and production of RA in callus culture of Satureja khuzistanica for the first time. In vitro callus induction was achieved from young shoot tip explants cultured on MS and B5 media supplemented with different concentrations of IBA (0.1, 1.0, 2.0 and 5.0 mgl-1) solely or in combination with cytokinins BAP and KIN...
Regulatory T cells (Tregs) are physiologically designed to prevent autoimmune disease and maintain self-tolerance. In tumour microenvironments, their presence is related to a poor prognosis, and they influence the therapeutic outcome due to their capacity to suppress the immune response by cell-cell contact and to release immunosuppressive cytokines. In this study, we demonstrate that Treg immu...
A sensitive, fast, low-cost and simple determination method was developed for the of nicotine in smokeless tobacco (Maras powder) using liquid chromatography-electrospray ionization tandem mass spectrometry. With method, amount Maras powder ashy determined confirmed. Chromatographic separation performed on a Hypersil Gold (2.1 mmx200 mm, 1.9 um) at 30 ◦C with gradient 0.2% acetic acid water ace...
