Hypothermic arrest, potassium arrest, and ischemic arrest, either singly or in combination, with or without coronary perfusion were studied in an isolated perfused rat heart preparation. Procedures that permitted the maintenance of high cellular levels of adenosine triphosphate (ATP) and creatine phosphate during arrest, e.g., coronary perfusion with hypothermic solutions or solutions containin...

I t has previously been demonstrated that dietary potassium deficiency in animals is associated with low serum chloride and elevated serum bicarbonate concentration (1-5). In 1950 the present authors described a decrease of intracellular carbon dioxide in the skeletal muscle of potassium-deficient rats (6), an observation which has since been confirmed by others (7). The present communication p...

PURPOSE To present a failed macular hole surgery with gas microbubble retention within the hole. METHODS A 68-year-old female patient with a Stage 2 macular hole underwent vitrectomy with removal of posterior hyaloid and 12% C3F8 gas injection. Because the macular hole was Stage 2 and posterior hyaloid was observed to be firmly attached over the macular area, no attempt was made for peeling o...

BACKGROUND Concern about a child's flat foot posture is a common reason for frequent clinical consultations for an array of health care and medical professionals. The recently developed paediatric flatfoot clinical-care pathway (FFP) has provided an evidence based approach to diagnosis and management. The intra and inter-rater/measurer reliability of the FFP has been investigated in this study....

A novel actinobacterium, designated strain JXJ CY 19T, was isolated from a culture mat of Microcystis aeruginosa FACHB-905 collected from Dianchi Lake, South-west China. 16S rRNA gene sequences comparison of strain JXJ CY 19T and the available sequences in the GenBank database showed that the strain was closely related to Modestobacter marinus 42H12-1T (99.1% similarity) and Modestobacter roseu...

The electrochemical behaviors of thiazolidine (tetrahydrothiazole) on gold and platinum electrodes were investigated in a Britton-Robinson buffer (pH 2.77-11.61), acetate buffer (pH 4.31), phosphate buffer solutions (pH 2.11 and 6.38) and methanol or acetonitrile containing various supporting electrolytes. Detection was based on a gold wire electrochemical signal obtained with a supporting elec...

The salt of milk constitutes a small part of milk (8-9 g.L(-1)); this fraction contains calcium, magnesium, sodium and potassium for the main cations and inorganic phosphate, citrate and chloride for the main anions. In milk, these ions are more or less associated between themselves and with proteins. Depending on the type of ion, they are diffusible (cases of sodium, potassium and chloride) or...
