background: recent results have provided increasing evidence to support involvement of membrane damage in the mechanism of ionizing radiation induced killing of mammalian cells. these findings have stimulated renewed interest in evaluating the damage to membrane as a primary initiator in radiation-induced cell killing especially in apoptotic death. the present study was aimed to gain deeper ins...

Recovery of sugars from cane molasses (i.e. the by-product of sugar industries) is of great interest to industry and academia. The prerequisite for refning cane molasses is removal of pigments and suspended solids present in the molasses. In this work, the utilization of membrane separation for clarifcation and decoloration of cane molasses has been examined. Three oper...

To explore the function of light-harvesting complex protein (LHCP) in Arabidopsis growth and development, the Leclere and Bartel seed collection was screened. In this collection randomly cloned cDNAs are expressed under the CaMV35S promoter. A pale green line has been identified and characterized in more details. Analysis of the inserted cDNA in the pale green line showed it encodes LHCB1 prote...

Olive leaves are considered to have great potential as natural sources of antioxidants and phenolic compounds. In this study, dried olive were extracted using four different solvents (water, methanol, ethanol, 80:20(v/v) methanol-water) with ultrasonic-assisted extraction. The biochemical (total phenolics flavonoids, total protein, free amino acids, soluble, reducing sugars) antioxidant activit...

Greenhouse-cultured, container-grown seedlings of Aleppo pine (Pinus halepensis Mill.), radiata pine (Pinus radiata D. Don), and interior Douglas-fir (Pseudotsuga menziesii var. glauca (Beissn.) Franco) were cold acclimated and deacclimated in growth chambers over 24 weeks. Needle and root cold hardiness and root growth potential (RGP) were measured weekly. Root, needle and stem analyses for so...

The performances of two-phase polymer-liquid PEBAX®/polyethylene glycol (PEG) and three-phase polymer-liquid-solid PEBAX®/PEG/MWNT thin film composite membranes for CO2 and CH4 permeation were studied. The effect of temperature and MWNT/PEBAX® ratio on single gas (CO2 and CH4) permeability was investigated. The permeat...
