The susceptibility to the fouling of the NiTi and Ti6Al4V alloys due to the adhesion of microorganisms and the biofilm formation is very significant, especially in the context of an inflammatory state induced by implants contaminated by bacteria, and the implants corrosion stimulated by bacteria. The aim of this work was to examine the differences between the sulphur-oxidizing bacteria (SOB) an...

304 stainless steel was tested under the media without Sulfate-reducing bacteria (SRB) and with SRB. The corrosion behaviors of 304 stainless steel in SRB and without SRB medium were studied by measuring the open circuit potential, the polarization curves and electrochemical impedance Spectrum,weight loss measurements to get the changes of fore-and-aft corrosion fouling. The open circuit potent...

Abdel Sami Microbial Biotechnology Department, National Research center, Dokki, Cairo, Egypt [email protected] Abstract: Sulfate-reducing bacteria (SRB) represent a class of anaerobic microorganisms that conduct dissimulatory sulfate reduction to obtain energy. The present study aimed to detect and control SRB...

Plant coumarins are important components of the human diet and a number them considered to possess chemopreventive therapeutic properties against cancer. Scopoletin, natural coumarin component has been shown inhibit growth many cancer cells. In this study, cytotoxic activity scopoletin was studied neuroblastoma cells SHSY5Y. The evaluated by Sulphorhodamine B (SRB) assay xCELLigence system. It ...

crude glycerol (cg) is an abundantly available and cheap by-product from biodiesel production. value-added applications for cg are highly wanted by industry and several processes such as the use of cg for enhanced oil recovery have been proposed. the aim of this study was to evaluate the sulfide production of sulfate-reducing bacteria (srb) indigenous to oil reservoirs using cg as substrate. th...

Avian leukosis virus subgroup J (ALV-J) was first isolated from meat-producing chickens that had developed myeloid leukosis. However, ALV-J infections associated with hemangiomas have occurred in egg-producing (layer) flocks in China. In this study, we identified an ALV-J layer isolate (HLJ13SH01) as a recombinant of ALV-J and a Rous sarcoma virus Schmidt-Ruppin B strain (RSV-SRB), which contai...

Acetylated betulinic acid ( BA ) was converted into mono-substituted benzylamides 2 – 14 . Screening in SRB assays showed them as cytotoxic for a variety of different human tumor cell lines. While parent not within the limits assay (cut-off 30 ​μM), target amides were cytotoxic. Their bioactivity well their cell/non-tumor selectivity depended on substitution pattern aromatic ring. The most acti...

BACKGROUND Selective reporting bias (SRB), the incomplete publication of outcomes measured or of analyses performed in a study, may lead to the over- or underestimation of treatment effects or harms. Cochrane systematic reviews of interventions are required to assess the risk of SRB, achieved in part by applying the Cochrane risk of bias tool to each included randomised trial. The Cochrane Hand...
