Pregnancy increases the urinary excretion of chemicals in women and rodents. It is unknown whether the enhanced clearance of drugs during pregnancy involves changes in the expression of transporters that mediate chemical secretion and reabsorption. The purpose of this study was to quantify the mRNA and protein expression of efflux transporters in kidneys from virgin and pregnant mice on gestati...

Vesicular release of neurotransmitter is the universal output signal of neurons in the brain. It is generally believed that fast transmitter release is restricted to nerve terminals that contact postsynaptic cells in the gray matter. Here we show in the rat brain that the neurotransmitter glutamate is also released at discrete sites along axons in white matter in the absence of neurons and nerv...

Patients undergoing oesophagectomy often have nutritional needs at the time of diagnosis and in the post-operative period. The aim of this article is to review the current literature and report on the author’s experience of routine feeding jejunostomy insertion following oesophagectomy. The records of forty-eight consecutive patients undergoing oesphagectomy under the author’s care were reviewe...

OBJECTIVE The purpose of this study was to evaluate the release of formaldehyde by some root canal filling materials. STUDY DESIGN Two older endodontic sealers, AH 26 and Endomethasone, and 2 recently available sealers, AH Plus and Top Seal, were analyzed. Infrared and electronic spectroscopy were used to determine formaldehyde content after set of the materials. RESULTS Analysis showed tha...

To evaluate the significance of the refractory period and conduction time of the AV node for reentrant tachycardias incorporating the AV node, the effective refractory period of the AV node (ERP) and AH interval (AH) during atrial pacing at various cycle lengths were measured in 12 anesthetized dogs after verapamil administration. ERP-AH tended to be constant in each dog at different cycle leng...
