1. 1. Studies of native and Cd(II)-substituted carbonic anhydrases with special reference to their interaction with inhibitors

   Författare :Lena Tibell; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbonic anhydrase; Cd II ; 113-Cd II -NMR; inhibition; catalytic mechanism;

   Sammanfattning : The major aim of this work has been to gain further insights into the catalytic mechanism of carbonic anhydrase (carbonate hydro-lyase, EC 4.2.1.1). LÄS MER

3. 2. Simulation of Phosphorus, Zinc and Cadmium Mass Flow in Dairy Farming Systems

   Författare :Anna-Karin Modin Edman; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Miljöstudier; Environmental studies; management; Cd; Zn; P; mass balance; system analysis; simulation;

   Sammanfattning : A simulation model, FARMFLOW, was developed for the calculation of phosphorus (P), zinc (Zn) and cadmium (Cd) stocks, flows and balances in different parts of a dairy farming system. The simulated continuous change in element stocks within the farming system enables evaluation of the long-term effects of management practices. LÄS MER

4. 3. Randomised, controlled trials of patient education with special reference to heart failure and joint diseases

   Författare :Agneta Björk-Linné; Malmö Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; randomisation; computer-technology; CD; controlled trial; drugs; drug interactions; health care cost; heart failure; interactive; Social medicine; joint diseases; patient education; knowledge; Socialmedicin; samhällsmedicin;

   Sammanfattning : In order to improve the treatment and care of patients with chronic diseases, controlled studies have to be performed continuously. It is widely believed that giving education/information to patients will increase their knowledge and compliance, which will decrease medical events and cost. LÄS MER

5. 4. Insight into the mitochondrial apoptotic pathway : The interplay of the pro-apoptotic Bax protein with oxidized phospholipids and its counterplayer, the pro-survival Bcl-2 protein

   Författare :Marcus Wallgren; Gerhard Gröbner; Marco Colombini; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; apoptosis; Bax; Bcl-2; CD; cell-free protein synthesis; DSC; membrane; mitochondria; oxidized phospholipids; reconstitution; solid state NMR; biologisk kemi; biological chemistry;

   Sammanfattning : Apoptosis plays a crucial role in multicellular organisms by preserving tissue homeostasis and removing harmful cells. The anti-apoptotic B-cell CLL/lymphoma 2 (Bcl-2) and the pro-apoptotic Bcl-2-associated X protein (Bax) act as major regulators of the mitochondrial apoptotic pathway. LÄS MER

7. 5. Interactions of Anticancer Active Platinum(II) Complexes with DNA

   Författare :Johan Kjellström; Bröstcancer-genetik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; polyelectrolyte; medium effects; salt dependence; DSC; CD; HPLC; oligonucleotide; hairpin; DNA; anticancer active platinum II compounds; kinetics; mechanism; Oorganisk kemi; Cytology; oncology; cancerology; Cytologi; onkologi; cancer;

   Sammanfattning : The kinetics and mechanism for interactions of the anticancer active platinum(II) complexes cis-[PtCl2(NH3)2)], cis-[PtCl2(NH3)(c-C6H11NH2)], and trans-[PtCl2-(NH3)(quinoline)] with DNA have been studied using a combination of HPLC, circular dichroism (CD), UV/vis spectroscopy, and differential scanning calorimetry (DSC). Reactions of the monoaqua forms (charge = +1) of these complexes with single-stranded DNA oligonucleotides, typically between 13-17 bases long, were found to depend on i) the composition of the reaction medium, ii) the exact nature and location of the platination target, and iii) on the DNA structure.
