potassium concentrations by flame photometry (within batch SD=0 03 mmol/l). The Mann-Whitney U test and Spearman's rank correlation coefficient were used in statistical analysis. The median (range) difference in potassium concentration between serum and plasma in the 43 patients with rheumatoid arthritis was 0 3 (0 1-1 3) mmol/l, which was significantly greater (p<0 001) than that in the 21 con...

Potassium ion sensors are important for the study of concentration profiles in tissues. The synthesis a cryptand suited potassium ions and crystal structure it with chelated sodium presented.

A cDNA encoding a novel, inwardly rectifying K+ (K+in) channel protein, SKT1, was cloned from potato (Solanum tuberosum L.). SKT1 is related to members of the AKT family of K+in channels previously identified in Arabidopsis thaliana and potato. Skt1 mRNA is most strongly expressed in leaf epidermal fragments and in roots. In electrophysiological, whole-cell, patch-clamp measurements performed o...

Phosphofructokinase (EC 2.7.1.11) from carrot roots was activated by a number of salts. Increase in salt concentration beyond the optimum generally led to a decrease in enzyme activity. Salts of the multivalent anions sulfate and phosphate were very effective activators and inhibitors. Potassium acetate and potassium succinate were also activators. Potassium tartrate and potassium citrate produ...

a serious hazard to patients during orthotopic liver transplantation is hyperkalemia. although the most frequent and hazardous hyperkalemia occurs immediately after reperfusion of the newly transplanted liver, morbid hyperkalemia could happen in the other phases during orthotopic liver transplantation. however, pre-anhepatic hyperkalemia during orthotopic liver transplantation is rare. this rep...

Factors influencing transport of potassium in the human small bowel were studied using perfusion techniques in normal subjects and in patients with ileostomies. In the small intestine of normal subjects and in the ileum of ileostomy patients, potassium is distributed across the mucose in a passive transport process. Potassium transport in the jejunum was influenced to a large degree by solven...

BACKGROUND There is an increase in number of patients with chronic kidney disease (CKD) in Uganda's health facilities looking for different options of preparing matooke (bananas), their staple food. OBJECTIVE To establish and evaluate an effective method of removing potassium from bananas (matooke). METHODS Bananas were sampled from 5 markets in Kampala, Uganda. Deionized water was used to ...
