A method is described for estimating plasma and urinary hemoglobin concentrations as low as 3 mg/L. The assay measures at 528 nm the rate of peroxidation of chlorpromazine by hemoglobin and is not affected by ascorbate and bilirubin concentrations up to 500 mumol/L. Results by this method (mean +/- SD: 54.4 +/- 41.6 mg/L; n = 19) correlated well with those by a scanning spectrophotometric metho...

Single and mixed oxide Al/Zr-pillared clay (Al/Zr-PILC) catalysts were synthesized and tested for catalytic wet air oxidation (CWAO) of aqueous phenol solution under milder conditions, in a semi-batch reactor. The catalysts were synthesized from natural bentonite clay using ultrasonic treatment during the aging and intercalation steps and were characterized <...

The drought tolerance of two local varieties Zea mays L. (var. indentata and var. everta) were studied using different concentrations (0 g/l, 3 g/l 5 g/l) polyethylene glycol (PEG) in Murashige Skoog (MS) medium. maize seeds surface sterilized with 10% (v/v) sodium hypochlorite for 15 minutes subsequently 70% ethanol 1 minute thereafter rinsed thrice sterile water. inoculated the growth media o...

Tuning recombinant protein expression is an approach which can be successfully employed for increasing the yield of recombinant protein production in high cell density cultures. On the other hand, most of the previous results reported the optimization induction conditions during batch and continuous culture of recombinant E. coli, and consequently fed-batch culture have received less attention....

Lamivudine belongs to the set of antiviral agents effective against hepatitis B virus infection. Given case reports on liver injuries after certain antiviral agent treatments, this study examined the effects of lamivudine on alanine aminotransferase (ALT) and total bilirubin (TB) using a medical system database. A total of 1,321 patients taking lamivudine alone or with others were evaluated usi...

The application of biofertilizers constitutes one of the main components of nutrient management with a fundamental role in sustainable agriculture and the improvement of plant qualitative traits. The present research assessed the effect of various treatments of phosphate solubilizing bacteria including Pantoea agglomerans strain P5 and Pseudomonas putida</...

Extremely low-liquid ammonia (ELLA) pretreatment using aqueous was investigated in order to enhance the enzymatic saccharification of corn stover and subsequent ethanol production. In this study, treated with an solution at different loading rates (0.1, 0.2, 0.3 g NH3/g biomass) various liquid-to-solid (L/S) ratios (0.55, 1.12, 2.5). The ELLA conducted elevated temperatures (90–150 °C) for exte...
