  2. 1. Effects of Dehydration and Blockade of the Renin-Angiotensin System in the One-humped Camel (Camelus dromedarius)

    Author : Mahmoud Al Haj; Fred Nyberg; Santi Spampinato; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood; biochemical analysis; catecholamine; colorimetric assay; cortisol; dehydration; dromedary camel; glutathione; hematological analysis; HPLC; insulin- like growth factor-1; losartan; plasma; receptors; radioimmunoassay; serum; Pharmaceutical Science; Farmaceutisk vetenskap;

    Abstract : The one-humped or the dromedarian camel is a pseudo-ruminant mammal, well adapted to the hot and dry climates of the desert. Its ability to withstand torrid heat and extreme desiccation is of paramount importance to its survival. READ MORE

  4. 2. Analysis of plant growth regulating substances

    Author : Barbro Andersson; Bo Jansson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant regulators; phytohormones; pine; spruce; anther; abscisic acid; 3-indoleacetic acid; gibberellin Ag; N- 3-indoleacetyl -aspartic acid; dichlorophene; Amberlite XAD-7; identification; quantification; GC; HPLC; GC-MS; GC-MID; Hormoner;

    Abstract : Natural plant growth regulators (phytohormones) are a group of organic compounds which, in very small amounts, act as regulators of physiological processes in plants.Methods were developed for the analysis of phytohormones in samples from Norway spruce (Picea abies (L.) Karst.) and Scots pine (Pinus sylvestris (L. READ MORE

  5. 3. Analysis of ginesenosides

    Author : Jian-fang Cui; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : New analytical methods were developed in order to evaluate commercial ginseng preparations and to allow studies on urinary excretion of ginsenosides in humans after consumption of ginseng preparations. An optimized alkaline procedure was developed for cleavage of the glycosidic bonds that was clearly superior to previously reported hydrolysis procedures of ginsenosides because of (a) completeness of the reaction and (b) absence of the artifacts found in acid hydrolysis.

  6. 4. Data analysis of non-targeted mass spectrometry experiments

    Author : Erik Tengstrand; Magnus Åberg; Olav Kvalheim; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Chemometrics; mass spectrometry; HPLC; metabolomics; Analytical Chemistry; analytisk kemi;

    Abstract : Data processing tools are valuable to the analytical chemist as they can speed up the analysis, and sometimes solve problems that are not feasible to solve in a traditional manner. However, the complexity of many data processing tools can make their use daunting for the inexperienced user. READ MORE

  7. 5. The structural basis for the catalytic specificity of manganese lipoxygenases : 3D structure analysis of the lipoxygenase of Magnaporthe oryzae

    Author : Anneli Wennman; Ernst H. Oliw; Marcia Newcomer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; oxylipin; lipoxygenase; crystal structure; crystallography; HPLC; mass spectrometry; yeast; site-directed mutagenesis; fungi; Biochemical Pharmacology; Biokemisk farmakologi;

    Abstract : Lipoxygenases (LOX) catalyze regio- and stereospecific oxygenation of polyunsaturated fatty acids to hydroperoxides. These hydroperoxides are further metabolized to leukotrienes and lipoxins in mammals, and are involved in asthma and inflammation. LOX of animals and plants contain iron as catalytic metal (FeLOX).
