Phosphorus is an essential nutrient for all living organisms. In bacteria, the preferential phosphorus source is phosphate, which is often a limiting macronutrient in many areas of the ocean. The geochemical cycle of phosphorus is strongly interconnected with the cycles of other elements and especially iron, because phosphate tends to adsorb onto iron minerals, such as iron oxide formed in oxic...

BACKGROUND In a previous paper, we reported the accomplishment of a cold gene-expression system for the recombinant secretion of heterologous proteins in Pseudoalteromonas haloplanktis TAC125. This system makes use of the psychrophilic alpha-amylase from P. haloplanktis TAB23 as secretion carrier, and allows an effective extra-cellular addressing of recombinant proteins. However, Pseudoalteromo...

Chronic kidney disease (CKD) is an international public health problem affecting about 5–10% of the population. KDOQI guidelines highlight importance measuring parathyroid hormone levels annually once diagnosed with CKD. If are maintained within target range, then various complications can be prevented by adequate treatment. 1. To measure Calcium, Phosphorus, Alkaline phosphatase and in patient...
