Olive pomace (OP) was used as raw material to extract cellulose by multi-step chemical method, and the extracted characterized. The two steps of alkali treatment (alkali concentration, reaction time temperature) bleaching (H2O2 NaOH were optimized. results showed that optimum conditions for follows: concentration 6%, 2 h, temperature 95 °C; optimal 7.5% H2O2 solution, 5% NaOH, 75 °C. After trea...

At least two types of complexes are detectable between Escherichia coli DNA topoisomerase I (w protein) and double-stranded DNA. If the duplex DNA is highly negatively supercoiled, the enzyme forms a complex with properties similar to its complex with singlestranded DNA: it is stable in a concentrated NaCl or CsCl solution, but addition of a minute amount of Mg(I1) to the salt solution readily ...

Saline-alkali stress is one of the major abiotic stresses that severely affect rice yield. However, mechanism by which saline-alkali regulates grain filling in still unclear. In this study, Oryza sativa L. spp. Indica cultivar Chaoyou1000 (C1000) was exposed to post-anthesis conditions at 6 days after anthesis, significantly reduced weight suppressing accumulation starch and non-structural carb...

In this paper, two novel alkali clearable disperse dyes were synthesized. 4-flourosulfonyl aniline and 2-nitro-4-flourosulfonyl aniline were utilized as the diazo components and 2- naphthol as the coupling component. The DSC, FTIR, 1HNMR and UV-Vis analyses were used to characterize the synthesized intermediates and dyes. The synthesized dyes were used to dye polyester fibers and their dyeing p...

PURPOSE To investigate the effects and mechanisms of fasudil hydrochloride (fasudil) on and in alkali burn-induced corneal neovascularization (CNV) in mice. METHODS To observe the effect of fasudil, mice with alkali-burned corneas were treated with either fasudil eye drops or phosphate-buffered saline (PBS) four times per day for 14 consecutive days. After injury, CNV and corneal epithelial d...

Grape stems are a by-product of wine production which is managed as waste. Animal feeding arises potential alternative. However, its practical use may be compromised by high lignin content. In this sense, hydrolysis emerges strategy to increase fibre digestibility. addition, due and variable moisture content, it should dried prevent microbial deterioration washing pre-treatment reduce sugar con...

Chemical burns take up a high proportion of burns admissions and can penetrate deep into tissues. Various reagents have been applied in the treatment of skin chemical burns; however, no optimal reagent for skin chemical burns currently exists. The present study investigated the effect of topical body protective compound (BPC)-157 treatment on skin wound healing, using an alkali burn rat model. ...
