BACKGROUND In patients treated by maintenance hemodialysis the relationship to survival of hemoglobin level and administered epoetin-alfa and intravenous iron is controversial. The study aim was to determine effects on patient survival of administered epoetin-alfa and intravenous iron, and of hemoglobin and variables related to iron status. METHODS The patients were 1774 treated by maintenanc...

Extracellular polysaccharide (EPS) produced by five lactic acid bacteria (Limosilactobacillus fermentum B55, Limosilactobacillus B62, Lactiplantibacillus plantarum 7830, Pediococcus acidilactici B30, and Lactobacillus helveticus K2) were purified identified, their effects on the texture of fermented goat milk evaluated. The EPS fractions 1a, 2b, 3c, 4d, 5e strains K2, B30 obtained with ion exch...

The brown seaweed Alaria esculenta is the second most cultivated species in Europe, and it therefore of interest to expand its application by developing food products. In this study, a lactic acid bacteria consortium (LAB consortium) consisting three Lactiplantibacillus plantarum strains (relative abundance ~94%) minor amount Levilactobacillus brevis strain ~6%) was investigated for ability fer...

The secreted mannuronan C-5 epimerases from Azotobacter vinelandii form a family of seven homologous modular type enzymes, which appear to have evolved through duplications and point mutations in the individual modules. The catalytic A modules of these enzymes are responsible for generating the characteristic sequence distribution patterns of G residues in the industrially important polymer alg...

The use of a number of species of marine brown algae in the implementation of bioremediation strategies for toxic heavy metals is being considered and evaluated. The biosorption capacity of these algae for heavy metals resides mainly in a group of linear polysaccharides known as alginates that occur as a gel in the algal thallus. The potential for selective metal binding by the biomass of two s...

Pretreatment variables that could predict the response of chronic hepatitis C to interferon alfa treatment have not been fully assessed. Eighteen baseline variables were evaluated in a series of 100 consecutive patients treated with a 12 month course of interferon alfa. For the purposes of this study, response was defined as the return to normal of aminotransferase activities before the third m...

introduction: listeria monocytogenes is a gram positive bacteria, frequently found in the environment and is responsible for food-borne disease such as perinatal infections, septicameia and meningeonceohalitis in human and animals. material and methods: for this reason, distribution of the ctpa determinate among l. monocytogenes isolated from clinical environment, diry and poultry samples were ...

Alginate epimerases are large multidomain proteins capable of epimerising C5 on beta-D-mannuronic acid (M) turning it into alpha-L-guluronic acid (G) in a polymeric alginate. Azotobacter vinelandii secretes a family of seven epimerases, each of which is capable of producing alginates with characteristic G distribution patterns. All seven epimerases consist of two types of modules, denoted A and...

We describe a Jehovah's Witness patient who survived emergency repair of a leaking abdominal aortic aneurysm. In accordance with his beliefs, the patient expressed a wish not to be given blood and this was respected. At completion of surgery, his haemoglobin was 2.8 g dl-1 and his albumin was 8 g l-1. He was kept heavily sedated in the intensive care unit and treated with i.v. iron, folinic aci...
