Heavy metal pollution is a worldwide problem with serious environmental consequences. The objective of the present experiment was to investigate whether arginine as nitric oxide precursor and or polyamines substrate can decrease the destructive effects of oxidative stress induced by nickel contamination in Hyoscyamus niger plant. In this study the effects of arginine pretreatment on alkaloid co...

The pretreatment of the substrate, prior to Electroless Nickel (EN) plating, plays an important role in the corrosion protection provided by the EN deposit. Many factors in the pretreatment process can affect the corrosion resistance of the EN deposit. The details of mechanical treatment, chemical/elecuo polishing, acid activation, and pre-processing procedure (such as nickel strike) are among ...

The pretreatment neutrophil-to-lymphocyte ratio (NLR) is reportedly associated with the clinical outcomes of many cancers. However, it has not been widely investigated whether the pretreatment NLR is associated with the pathological characteristics of prostate cancer (PCa) and biochemical recurrence in PCa patients receiving radical prostatectomy (RP).In this cohort study, a total of 1688 PCa p...

Exposure of cellulosic biomass to temperatures of about 120-210 degrees C can remove most of the hemicellulose and produce cellulose-rich solids from which high glucose yields are possible with cellulase enzymes. Furthermore, the use of dilute sulfuric acid in this pretreatment operation can increase recovery of hemicellulose sugars substantially to about 85-95% of the maximum possible versus o...

Background and objectives For most of the application cereal materials, sample pretreatments are considered critical factors. Different (roasting amylase hydrolysis) prior to extraction were employed obtain oat protein (OP) from grains. The effect pretreatment on structure functional properties OPs was determined. Findings Analysis sodium dodecyl sulfate–polyacrylamide gel electrophoresis (SDS-...

One of the dominant species green algae growing along Mediterranean coast Egypt is Ulva lactuca. Pretreatment can have a major effect on biogas production because hydrolysis cell wall structure rate-limiting stage in anaerobic digestion (AD) process. The use ozone, new pretreatment, to boost from lactuca was investigated this study. Ozonation at various dosages used contrast untreated biomass, ...

In this study, the effect of pretreatment and solid-state fermentation (SSF) on tempeh protein content has been studied. Pretreatment SSF are important processes for producing high-quality tempeh. Based results analysis using a UV-Vis spectrophotometer at ?max = 540 nm, it is known that both cause reduced content. causes total (w/w) to decrease rapidly from 1.05% 0.82%, while dissolved 0.57% 0....
