Goji berry (Lycium barbarum L.) antioksidan özellikleri sayesinde son zamanlarda kullanılan fonksiyonel gıdalar arasında yer almaktadır. Anti-oksidatif, kardiyo-protektif, nöro-protektif, anti-diyabet, anti-kanser ve anti-tümör özelliklerinin yanı sıra daha birçok hastalığın tedavisinde koruyucu rol oynadığı bilinmektedir. Bu çalışmada 4 grup oluşturulmuştur. Gruplar; (1) Kontrol grubu; (2) Gru...

Представлены результаты исследования адсорбционных свойств сшитых эпихлоргидрином хитозановых сфер. В ходе была разработана методика получения и сшивки сфер, а также магнитно-разделяемых композитов на их основе. Адсорбционная способность сфер исследована примере водных растворов NiCl2 K2Cr2O7 при варьировании концентрации ионов Ni2+ Cr2О7 2- . Было показано, что адсорбционное равновесие в случа...

Microalgae occupy a key trophic level since primary producers at the base of aquatic food chain. Moreover, they are well suited for ecotoxicological tests because easily cultured and sensitive to contaminants. However, species sensitiveness same chemicals can vary greatly. Thus, we characterized non-standardized diatom Chaetoceros tenuissimus by means growth inhibition, biochemical, infrared-sp...

Chromium (Cr) is an element present in nature mineral form. It has a dual effect, both as essential micronutrient and carcinogenic agent depending on its chemical form concentration. various environmental matrices such water, soil, air, coming from natural anthropogenic sources, causes harmful effects biota, ecosystems, even human beings. This study's objective was to evaluate chromium toxicity...

the quenching of quinine fluorescence intensity in the presence of some anions in aqueous solution at ambient temperature has been investigated. the quenching is found to be collisional or dynamical in nature. this study reveals the order of two groups of quencher: nai > nabr > nacl > naf and k2cr2o7 > kmno4 >na2so4 > naclo3. increasing anion size in the both groups leads to an  increase in the...
