2. 1. Regulation and transport mechanisms of eukaryotic aquaporins

   Author : Madelene Palmgren; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aquaporin; Membrane protein; Transport; Glycerol; Aquaglyceroporins; Regulation; arsenite;

   Abstract : Aquaporins are found in all kingdoms of life where they are involved in water homeostasis. They are small transmembrane water conducting channels that belong to the ancient protein family Major Intrinsic Proteins (MIP). READ MORE

5. 3. Ion transport in exocrine glands with reference to cystic fibrosis

   Author : Ailing Zhang; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; ion transport; cystic fibrosis; submandibular gland; airway submucosal gland; X-ray microanalysis; cytosolic Ca2 concentration; immunocytochemistry; Cellbiologi; Cell biology; Cellbiologi; Human Anatomy; anatomi;

   Abstract : Aspects of ion transport in rat submandibular gland acinar cells at the subcellular level, and the regulation of chloride secretion and calcium mobilization in cultured pig tracheal gland acinar cells were studied with reference to the disease cystic fibrosis.In adult rat submandibular gland acinar cells, both cholinergic and α-adrenergic stimulation induced efflux of K+ and of C1-, but the response was generally less with α-adrenergic stimulation.

6. 4. Prokaryotic Arsenic Resistance - Studies in Bacillus subtilis

   Author : Emil Aaltonen; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ArsB; Bacillus subtilis; arsenic resistance; arsenate reduction; arsenite transport; gene regulation; arsenate; ArsR; arsenite; transmembrane topology; Acr3; ArsK;

   Abstract : Arsenic is a toxic metalloid which is found all over the globe. Due to its toxicity and wide abundance, all living organisms have evolved intrinsic arsenic resistance systems. In this study, three proteins that provide arsenic resistance in the Gram-positive bacterium Bacillus subtilis have been investigated. READ MORE

7. 5. Gastroduodenal epithelial transport in patients with cystic fibrosis

   Author : Karin Edshage Hallberg; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cystic fibrosis; CFTR; intestinal motility; gastric secretion; IgA; Ussing chamber; intestinal permeability; genotype;

   Abstract : Cystic fibrosis (CF) is an inherited disease where respiratory failure due to chronic lung infection is the major cause of death. A defective protein, cystic fibrosis transmembrane conductance regulator (CFTR) alters chloride epithelial transport. READ MORE
