In diagnostic and research bacteriology settings with budget and staff restrictions, fast and cost-effective genome extraction methods are desirable. If not inactivated properly, cellular and/or environmental DNA nucleases will degrade genomic material during the extraction stage, and therefore might give rise to incorrect results in PCR experiments. When crude cell extracts, proteinase K–treat...

different species of artemisia (asteraceae) have shown to exhibit antitumor activity. the aim of this study was to identify the antiproliferative effect of artemisia aucheri boiss (a.aucheri) from iran on cultured human cancer cells. aerial parts of artemisia aucheri boiss. were collected from chahar bagh region (2150 m altitude, sep. 2011),golestan province, iran.the dried powdered aerial part...

garlic and onions as dietary constituents and medicines have been used for many disorders which dates back to the early civilization. it has been shown that different species of allium have immunomodulating effects. in this study, we sought to determine if methanolic and chloroformic extracts of allim fistulosum l. (leek) have any effect on cell-mediated immune response in mice. methanolic and ...

the plants of the genus salvia synthesize several types of secondary metabolites with antimicrobial, cytotoxic, and radical scavenging activities and are used in the folk medicine of different countries. eleven salvia species including s. aegyptiaca, s. aethiopis, s. atropatana, s. eremophila, s. hypoleuca, s. limbata, s. nemorosa, s. santolinifolia, s. sclarea, s. syriaca, and s. xanthocheila ...

Background: One of the key questions in biochemistry is why cell becomes aged and what are the involved factors? Why cell growth is stopped after some divisions and cells become senescent? This occurs in a greater frame in the whole body and cells dye after a while. Androgenetic alopecia (AGA) is characterized by a loss or decrease in hair follicle size, which could be related to the loss of ha...

Rheum turkestanicum Janischew. (Polygonaceae) is a plant that grows in central Asia and in north-east of Iran. Traditionally, people use roots of R. turkestanicum as an anti-diabetic and anti-hypertensive as well as anticancer agent. In this study the cytotoxicity and apoptogenic properties of ethyl acetate (EtOAc), n-hexane and H2O extracts from Rheum turkestanicum Janischew. (Polygonaceae) ro...

background and objectives: there is a profound inclination among people toward consumption of herbs and herbal products. some of these products are harmful while health-promoting potentials of some others should be discovered. in the present study the antibacterial, antioxidant, acute and subchronic and cancer cell toxicity of methanolic and aqueous extracts of rosa damascena mill. was studied....

Introduction: Some studies have demonstrated the potential of herbal drugs for the treatment of various diseases associated with impaired vascular nitric oxide (NO). For diagnosis of the mechanism of these herbal plants, it seems necessary to evaluate the herbal extracts on the Endothelium cell. The aim of the study was to investigate the effect of extract of Trigonella foenum-graecum (T.foenum...

Background and objectives: The aerial part extracts of Eremostachys macrophylla  from Labiatae family, which has been traditionally used in wound healing, snake bites, rheumatism and joint pains, were investigated for general toxicity, anti-proliferative, free radical scavenging and anti-bacterial effects.Moreover, preliminary phytochemical investigations were carried ...

The methanolic extracts of Indigofera aspalathoides (MEIA) and Wedelia calendulaceae (MEWC) were evaluated for their anticancer activity against Ehrlich Ascites Carcinoma (EAC) in Swiss albino mice. On day 1, the extract of Indigofera aspalathoides at a dose of 250 and 500 mg/kg body weight and the extract of Wedelia calendulaceae at a dose of 250 and 500 mg/kg body weight were administered ora...
