Arabidopsis arenosa is a good candidate for phytoremediation due to its high tolerance Zn and Cd as well accumulation ability. However, small size low biomass are the largest obstacles applying it on broad scale. The aim was obtain polyploid specimens, which tend have higher increase translocation capacity of heavy metals in this metal-tolerant plant. Doubled polyploids (octaploids) were obtain...
1953, the year of Watson and Crick, bore witness to a less acclaimed yet highly influential discovery. Jean Weigle demonstrated that upon infection of Escherichia coli, λ phage deactivated by UV radiation, and thus unable to form progeny, could be reactivated by irradiation of the bacterial host. Evelyn Witkin and Miroslav Radman later revealed the presence of the SOS regulon. The more than 40 ...
Cancer is a major global problem and is the second leading cause of mortality in the developed countries.Resistance to current chemotherapeutics and high incidence of adverse effects are the two principal reasons for developing new anticancer agents. Phenylacetamide derivatives can act as potential anticancer agents. Synthesis and screening of 2-(4-Fluorophenyl)-N-phenylacetamide derivatives in...
The description of Galanthus lebedevae from limestone canyons foothills in south-east Sochi is presented. species belongs to series Latifolii, subseries Viridifolii (Kem.-Nath.) A. P. Davis. It shows an external morphological similarity with the sympatric Colchian G. platyphyllus, krasnovii, panjutini, and woronowii, however, it differs sharply all listed content nuclear (2C) DNA, phenology, ec...
Lung cancer remains a leading cause of disease globally, with smoking being the largest single cause. Phase I enzymes, including cytochrome P(450), family 1, subfamily A, polypeptide 1 (CYP1A1), are involved in the activation of carcinogens, such as polycyclic aromatic hydrocarbons, to reactive intermediates that are capable of binding covalently to DNA to form DNA adducts, potentially initiati...
The disulfiram and copper complex (DSF:Cu) has emerged as a potent radiosensitising anti-cancer agent. The ability of copper to stabilise DSF in a planar conformation and to inhibit DNA replication enzymes stimulated our investigation of the effect of DSF:Cu on cell cycle regulation. Flow cytometry and immunoblotting were used to assess the effect of DSF:Cu on cell cycle progression of the neur...
Nuclear DNA content in gametophytes and sporophytes or the prostrate phases of the following species of Bonnemaisoniaceae (Asparagopsis armata, Asparagopsis taxiformis, Bonnemaisonia asparagoides, Bonnemaisonia clavata and Bonnemaisonia hamifera) were estimated by image analysis and static microspectrophotometry using the DNA-localizing fluorochrome DAPI (4', 6-diamidino-2-phenylindole, dilacta...
زمینه: سیتوکروم 1E4502P(1E2CYP) آنزیمی اصلی است که نقش عمدهای در فعالسازی و سمیتزدایی بسیاری از ژنوبیوتیکها، سرطانزاها (کارسینوژنها) و داروها ایفا میکند. بررسی انواع پلیمورفیسم در 1E2CYP بهعنوان یک ضرورت اولیه خطر ابتلا به انواع سرطان در صورت تماس با ترکیبات کارسینوژن، یافتههای متفاوتی داشته است. هدف از این بررسی تعیین فراوانی آللی و ژنوتیپی پلیمورفیسم B5*1E2CYP در جمعیت ایرانی و مقا...
This study was designed to answer the question: Is H3-thymidine uptake by nuclei of the mouse seminal vesicle evidence for DNA synthesis and mitosis, or does it signify some "metabolic" function of DNA unrelated to chromosome duplication? Mice were given an intraperitoneal injection of H3-thymidine. Six hours later Feulgen squashes of the seminal vesicle epithelium were made and covered with au...
