Sweet sorghum bagasse (SSB) from food processing and agricultural industry has attracted the attention for uses in production of biofuel, enzymes and other products. The alteration in lignocellulolytic enzymes by use of supplements in fungal pretreatment of SSB to achieve higher lignin degradation, selectivity value and enzymatic hydrolysis to fermentable sugar was studied. Fungal strain Coriol...

AIMS Nafcillin (Wyeth Laboratories, Philadelphia, PA, USA) has been reported to induce the metabolism of cyclosporin and warfarin, which are known substrates of cytochrome P-450 (CYP). However, there has not been any report to date on its possible interaction with nifedipine, an index substrate of the enzyme, CYP3A4. METHODS Nine healthy normotensive subjects participated in this randomized p...

This study aimed to evaluate the antidotal potency of tenocyclidine (TCP) that probably might protect acetylcholinesterase (AChE) in the case of organophosphate poisoning. TCP was tested alone as a pretreatment or in combination with atropine as a therapy in rats poisoned with (1/4) and (1/2) of LD(50) of soman. Possible genotoxic effects of TCP in white blood cells and brain tissue were also s...

Biogas production from biomass is an eco-friendly approach that offers renewable energy generation, waste recycling, biofertilizer along with maintaining environmental quality. Anaerobic decomposition a familiar practice used for biogas in worldwide, whereas only few substrates were convenient attaining desired methane concentration biogas. Hence, further advancements are necessary the explorat...

The potential of extracellular alkali stable and thermo tolerant xylanase produced by Bacilluspumilus SV-85S through solid state fermentation was investigated in pulp bleaching in association with conventional bleaching using chlorine and chlorine dioxide. The biobleaching of kraft pulp with xylanase was the most effective at an enzyme dose of 10 IU/g oven dried pulp, pH 9.0 and 120 min incubat...

Cassava production generates significant amounts of by-products such as leaves and tuber peel. Instead considering them waste, valorization aims to find sustainable ways utilize them. However, the presence cyanide insoluble fibers poses a major obstacle their conversion into valuable products. Therefore, objective this study is investigate changes in concentration quality cassava after mechanic...

Pretreatment of biomass before subjecting it to enzyme saccharification is crucial with regards to facilitating access of enzyme to biomass. Extrusion, as a continuous and cost-effective pretreatment method, combines heating with high shear and mixing resulting in much greater specific surface areas of biomass. The objective of this study was to examine the effect of extrusion as a pretreatment...

The serum level of galactosyltransferase was measured in a group of 218 patients with a variety of solid tumors and most with advanced disease. The pretreatment enzyme level showed little potential as a diagnostic tumor marker, and its change with treatment did not reflect the initial response. There was, however, a significant correlation between the length of survival and the pretreatment enz...

BACKGROUND Flowthrough pretreatment is capable of removing much higher quantities of hemicellulose and lignin from lignocellulosic biomass than batch pretreatment performed at otherwise similar conditions. Comparison of these two pretreatment configurations for sugar yields and lignin removal can provide insights into lignocellulosic biomass deconstruction. Therefore, we applied liquid hot wate...

The present study was designed to explore the mechanism of hesperidin action via the nitric oxide pathway in the protection against ischemic reperfusion cerebral injury-induced memory dysfunction. Male Wistar rats (200-220 g) were subjected to bilateral carotid artery occlusion for 30 min followed by 24 h reperfusion. Hesperidin (50 and 100 mg/kg, po) pretreatment was given for 7 days before an...
