2. 1. Sugar-modulated gene expression and cell division in cell culture and seedlings of A. thaliana

   Author : Sabine Kunz; Leszek A. Kleczkowski; Alison Smith; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; carbohydrates; cell culture; cell division; gene expression; homeostasis; live cell imaging; sugar-signals; sugar-analogues; Physiological Botany; fysiologisk botanik;

   Abstract : Throughout their life cycle, plants adjust growth in response to their developmental and environmental situation within the limits of their energetic capacities. This capacity is defined by the local sugar availability, which is constantly modulated through synthesis, transport and consumption of sugar. READ MORE

4. 2. UDP-sugar metabolizing pyrophosphorylases in plants : formation of precursors for essential glycosylation-reactions

   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical library screening; Cell wall synthesis; Glycosylation; Nucleotide sugars; Oligomerization; Protein structure; Reverse chemical genetics; Sugar activation; UDP-sugar synthesis; biokemisk farmakologi; biochemical pharmacology; biokemi; Biochemistry; biology; biologi; molekylärbiologi; Molecular Biology;

   Abstract : UDP-sugar metabolizing pyrophosphorylases provide the primary mechanism for de novo synthesis of UDP-sugars, which can then be used for myriads of glycosyltranferase reactions, producing cell wall carbohydrates, sucrose, glycoproteins and glycolipids, as well as many other glycosylated compounds. The pyrophosphorylases can be divided into three families: UDP-Glc pyrophosphorylase (UGPase), UDP-sugar pyrophosphorylase (USPase) and UDP-N-acety lglucosamine pyrophosphorylase (UAGPase), which can be discriminated both by differences in accepted substrate range and amino acid sequences.

6. 4. A structural study of ribokinase from Escherichia coli

   Author : Jill A. Sigrell; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; ATP-binding; conformational changes; kinase; ribose; X-ray crystallography; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

   Abstract : Ribokinase phosphorylates the abundant sugar ribose, using ATP in the presence of magnesium. The phosphorylation is the first reaction in ribose metabolism and the product, ribose-5-phosphate, can enter the pentose phosphate pathway and glycolysis. It can also be used in the synthesis of histidine and purines. READ MORE

7. 5. On Oral Health in Young Individuals with a Focus on Sweden and Vietnam : A Cultural Perspective

   Author : Brittmarie Jacobsson; Tomas Magnusson; Anders Hugoson; Jönköping University; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Child dentistry; dental caries; diet; epidemiology; gingivitis; immigrant; barntandvård; epidemiologi; gingivit; invandrare; karies; kost;

   Abstract : AIM: The overall aim of this thesis was to study culture as an oral health determinant for dental caries and gingivitis in children living in Jönköping, Sweden, in relation to children living in Da Nang, Vietnam.MATERIALS AND METHODS: In 1993 and 2003, cross-sectional studies with clinical examinations and questionnaires were performed in Jönköping, Sweden, with a random sample of 130 children from each of four age groups; 3, 5, 10 and 15 years.
