There is an increasing interest in the potential of bacterial sulfate reduction as an alternative method for sulfate removal from wastewater. Under anaerobic conditions, sulfate-reducing bacteria (SRB) utilize sulfate to oxidize organic compounds and generate sulfide (S2-). SRB were successfully isolated from sludge samples obtained from a local petroleum refinery, and used for sulfate removal. The effects of initial sulfate concentration, temperature and pH on the rate of bacterial growth and a

The study was designed to investigate the effects of leucineenkephalin (L-ENK) on the activity of alpha-naphthyl acetate esterase (ANAE) and myeloperoxidase (MPO) in haemolymph of the scallop Chlamys farreri. Our results indicate that MPO activity with DAB and DEA substrate solution was induced when the
concentration of L-ENK was 5 and 50 μg/ml, and the intracellular and extracellular MPO activity with two substrate solutions was
highest when the concentration of L-ENK was 50 μg/ml. However, b

Renewable energy is an increasing need in our society. Microbial fuel cell (MFC) technology represents a new form of renewable energy by generating electricity from what would otherwise be considered waste. It is possible to directly generate electricity-using bacteria while accomplishing wastewater treatment in processes based on microbial fuel cell technologies. When bacteria oxidize a
substrate, they remove electrons. Electric current generation is made possible by keeping bacteria separated

The hybridoma (H9r9) were cultured in roller bottles with two media viz IMDM and RPMI with FCS (3% & 5%). The parameters such as
cell count, cell viability and avidity were determined on a time course basis from day 1 to day 18, to assess the optimization of the
roller bottle process for the production of anti – D and to determine the influence of factors namely medium, serum concentration and
varying cell density. The cell viability and cell count remained significant upto 8 or 10 days. Cell

We have investigated the effect of luteolin, a flavonoid on colon cancer induced in rats by a colon specific carcinogen 1, 2 dimethylhydrazine (DMH). Rats were randomized into 5 groups of 10 animals each. Rats in group 1 received 1.0 ml of 0.5%
carboxymethyl cellulose (CMC) everyday via intragastric intubation and served as the untreated control. Group 2 rats received luteolin via intragastric intubation (p.o.) at a daily dose of 0.2 mg/kg body weight. The rats in groups 3 to 5 received DMH [20

Background: We report two rare cases of inflammatory cloacogenic polyps of the anorectum. The first case involves a 50
year old white female who presented with chronic diarrhea, prolapse, and rectal bleeding. The second case presents a 67 year old
white male who presented with hemorrhoids and rectal bleeding. It is hypothesized that correction of prolapse will resolve the
pathologic changes. In these two patients, at one year follow-up, there has been gradual resolution of pathologic changes fol
