Lumber used to construct raised garden beds is often treated with chromated copper arsenate (CCA). This project aimed to determine (i) how far As, Cu, and Cr had diffused away from CCA-treated wood surfaces in raised garden beds under realistic conditions, (ii) the uptake of these elements by crops, and (iii) the effect of CCA solution on soil bacteria. This study showed that As, Cu, and Cr dif...

Salvia chorassanica Bunge is one of the Iranian endemic species of Salvia. There is not any reported literature on S. chorassanica. This study was designed to examine the in-vitro anti-proliferative and proapoptotic effects of the methanol extract of S. chorassanica and its fractions on HeLa cell line. Cells were cultured in EX-CELL®, an animal free medium specially designed for HeLa cell line ...

Polyetheretherketone (PEEK) films were oxygen plasma treated to increase surface free energy and characterized by X-ray photoelectron microscopy, atomic force microscopy, and water contact angles. A parallel plate flow chamber was used to measure Staphylococcus epidermidis, Staphylococcus aureus, and U-2 OS osteosarcomal cell-line adhesion to the PEEK films in separate monocultures. In addition...

background: wharton’s jelly is an unlimited source of stem cells that can be used in cell therapy and tissue engineering without any ethical concern. it has been revealed the cell-free extract could be effective to induce cell differentiation. the objective of this study was to induce wharton’s jelly-derived mesenchymal stem cells (mscs) into hepatocyte-like cells by premeabilization of the cel...

introduction: selected probiotic lactobacilli have inhibitory effect and therefore may be use as biological preservative, so, the aim of this study was to present some data on isolation, growth, antimicrobial activity, effect of ph, heat, and sensitivity to proteolytic enzymes of lactobacillus. material and methods: isolation of lactic acid bacteria from sausage was done by using 1g of samples ...
