The biochemical methane potentials for typical fruit and vegetable waste (FVW) and food waste (FW) from a northern China city were investigated, which were 0.30, 0.56 m3 CH4/kgVS (volatile solids) with biodegradabilities of 59.3% and 83.6%, respectively. Individual anaerobic digestion testes of FVW and FW we re conducted at the organic loading rate (OLR) of 3 k g VS/(m3.day) using a lab-scale c...

seedlings of five canola genotypes (hyola308, hyola401, hyola60, optlon50, and rgs003), were grown in hoagland nutrient solution containing s1=0, s2=100, s3=200 and s4=300 mm nacl in controlled environment. such antioxidant activities as catalase (cat), ascobrate peroxidase (apx) and guaiacol peroxidase (gpx), as well as osmolyte concentration (proline), chlorophyll fluorescence and some enzyme...

background: it has been suggested that organophosphates may inhibit gamma-aminobutyric acid (gaba) metabolism in synaptosomal preparations. in the present investigation, we have assessed the interaction between paraoxon and the gaba system at synaptic level.   methods: synaptosomes were prepared from male wistar rats (200-250 g). cerebral cortex was dissected and homogenized, then centrifuged a...

In the present study, two pretreatment methods (thermal and biological pre-hydrolysis) were suggested for food waste (FW) with aim to enhance biomass conversion biogas production by anaerobic. The effects of thermal (TP), including TP at 60 °C 80 min, 100 °C, 120 140 30 well as pre-hydrolysis (BPH) 37 55 followed 40 h on anaerobic digestion performance FW evaluated in batch tests. Results compa...

Rosa persica with a distinctive red eye is a good candidate for addition to the breeding pool of roses. In order to optimize micropropagation of R. persica, three culture media (MS, QL and VS) were compared. The maximum growth rate was observed in the VS medium. Addition of FeEDTA (Fe: 65.4 mg/l), calcium gluconate (Cg: 2.7 g/l) and Gamborg vitamins (B5) instead of VS vitamins, alone or in comb...

Forward walking (FW) and backward walking (BW) are two important forms of locomotion in quadrupeds. Participation of the motor cortex in the control of FW has been intensively studied, whereas cortical activity during BW has never been investigated. The aim of this study was to analyze locomotion-related activity of the motor cortex during BW and compare it with that during FW. For this purpose...

We are the first to report allosterism during styrene oxidation by recombinant CYP2E1 and human liver microsomes. At low styrene concentrations, oxidation is inefficient because of weak binding to CYP2E1 (K(s) = 830 μM). A second styrene molecule then binds CYP2E1 with higher affinity (K(ss) = 110 μM) and significantly improves oxidation to achieve a k(cat) of 6.3 nmol · min(-1) · nmol CYP2E1(-...

The effects of ovine prolactin (oPRL) and striped bass prolactin (sbPRL; Morone saxatilis) on plasma osmolality, electrolyte balance, and gill Na(+),K(+)-ATPase activity were investigated in hypophysectomized (Hx), freshwater (FW)-acclimated, hybrid striped bass (M. saxatilisxMorone chrysops). They were kept in dilute (isoosmotic) seawater for about 10 days after surgery. Seven days after trans...
