Ergönül P.G., Nergiz C. (2010): Determination of organic acids in olive fruit by HPLC. Czech J. Food Sci., 28: 202–205. Organic acids (oxalic, citric, malic, and succinic) contents of Domat, Memecik and Uslu varieties of olives grown in Turkey were investigated using HPLC method. Organic acids were extracted from olives with water-methanol mixture solution 75:25 (v/v) and were analysed through ...

Cells from photoautotrophic cultures o f Chenopodium rubrum were fractionated for the iso­ lation o f purified chloroplasts and mitochondria. The subcellular localization o f the enzymatic activities involved in the metabolism o f malic acid was investigated. Highly purified chloro­ plasts were obtained from the protoplasts, whereas peroxisomes were still present in the mito­ chondrial fraction...

Thirty-five strains of malolactic bacteria were isolated from grapes and alcoholic and malolactic fermentations in two vineyards from northwestern Spain. These belonged to six species of the genera Lactobacillus and Leuconostoc. The results of their partial enological characterization showed that 47.5% utilized more than 80% of the initial malic acid.

Doxorubicin (DOX) is currently used in cancer chemotherapy to treat many tumors and shows improved delivery, reduced toxicity and higher treatment efficacy when being part of nanoscale delivery systems. However, a major drawback remains its toxicity to healthy tissue and the development of multi-drug resistance during prolonged treatment. This is why in our work we aimed to improve DOX delivery...

Translocation of Fe was studied in WF9 (Fe-efficient) and ys(1)/ys(1) (Fe-inefficient) maize (Zea mays L.) genotypes. Iron-deficient WF9 translocated more Fe to the tops than Fe-deficient ys(1)/ys(1). Malate and citrate contents of root saps increased nearly 2-fold and aconitate increased over 4-fold in both genotypes as Fe of nutrient solutions increased from 0.1 to 3 milligrams per liter. Rel...

the effect of anti-follicular stimulating hormone (fsh) on testicular lipid and the specific activity of testicular enzymes of the isocitrate dehydrogenase (icdh), pyruvate/malate dehydrogenase (mdh) and malic enzyme involved in lipogenesis were studied in mature bonnet monkeys, macaca radiata. immunization of monkey with anti-fsh for 24 days did not produce any significant changes in the body ...
