Exogenous [1-(14)C]oleic acid and [1-(14)C]linoleic acid were taken up and esterified to complex lipids by greening cucumber (Cucumis sativus L.) cotyledons. Both (14)C-labeled fatty acids were initially esterified to phosphatidylcholine prior to eventual accumulation in triacylglycerols and galactolipids. Kinetic data suggest that esterification occurs prior to desaturation and that phosphatid...

biofuels are the main substitute to fossil fuels. these fuels are less polluting in compari-son to fossil fuels and can be produced from agricultural material residues for use in die-sel engines. in this research work bioethanol was produced from potato waste. it was de-hydrated in a vapor phase using 3a zeolite and was used in combination with sunflower methyl ester oil and diesel fuel blendin...

background: the purpose of this work was to investigate the use of polyvinyl chloride (pvc) dyed with methyl red as a high dose radiation dosimetry. materials and methods: commercial pvc films from sabic made from resins pvc57s with thickness of 60 µm and methyl red with a molecular weight of 269.31 were used. irradiation was carried out using a 60co γ-ray generator with sources arranged in rec...

purpose: to compare the results of three-piece and one- piece hydrophobic acrylic posterior chamber intraocular lens (iol) with poly methyl metacrylate (pmma) iol implanted during lensectomy, posterior capsulotomy and anterior vitrectomy for congenital or developmental cataract. methods: this is a historical cohort study conducted on patients with congenital or developmental cataract who underw...

in this paper, the chemical functionalization of carboxylate multi-walled carbon nanotubes by methyl (triphenyl phosphoranylidene) acetate have been investigated. phosphorus ylides are important compound in organic chemistry. at first, methyl (triphenyl phosphoranylidene) acetate, synthesized from salt metod in two steps: the formation of the phosphonium salt and the deprotonation of the latter...

conclusions this study supports the preventative effects of aminophylline on apnea in extreme premature infants. in other words, the more premature an infant, the greater the preventative effect of aminophylline on the incidence of apnea and bradycardia. background a few studies have been carried on preventive drugs for apnea of preterm neonates. objectives this study aimed to assess the safety...

in recent years, the effects of heterogeneous catalysts for the oxidation of organic and inorganic pollutants in industrial wastewaters are spread. traditionally, these reactions are usually carried out using suspensions of photo-catalysts such as tio2. a chemical method including ticl4, al(no3)3, ethanol amine, ethyl acetoacetate and aqueous ammonia were used for the fabrication of tio2-al2o3 ...
