Hospital wastewater contains pathogenic agents and hazardous compounds; so, it will cause many risks on environmental and human health of different communities. The aim of this research was to investigate the efficiency of hospital wastewater treatment plant in north of Iran. This cross-sectional descriptive research was done on four hospital wastewater treatment plant in north of Iran during 2...

Dendritic cells (DCs) are key to the maintenance of peripheral tolerance to self-antigens and the orchestration of an immune reaction to foreign antigens. C-type lectins, expressed by DCs, recognize carbohydrate moieties on antigens that can be internalized for processing and presentation. Little is known about the exact glycan structures on self-antigens and pathogens that are specifically rec...

Relying on results of Hopkins-Morel, we show that, for X a quasiprojective variety over a field of characteristic zero, the canonical map Ωn(X)→ MGL 2n,n (X) is an isomorphism.

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...

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...
