Global ischemia was induced in isolated blood-perfused rabbit interventricular septa at 37 °C beating at 72 beats/min. Uptake of BaCl2 (0.85 JIM) or SrCl2 (0.4 JIM) during perfusion with solutions containing 2.5 mM CaCh was monitored by gamma probe. Since barium is not sequestered by sarcoplasmic reticulum, its uptake was used to monitor sarcolemmal function. The uptake of BaCl2 increased from ...

Introduction: Dill (Anethum graveolens), a herb from from Umbelliferae, is used traditionally to treat convulsion and increasing milk production. Its antimicrobial, antihyperlipidaemic, anti-hypercholesteroaemic effects and gastric acid secretion reducing effect have been reported. The spasmolytic effect of dill fruit on rat uterus has also been shown recently. The aim of present study was to i...

: Unwanted water production from oil and gas reservoirs is a serious problem for producers. Preformed particle gel (PPG) treatment is a benefit approach to control excess water production. Swelling percentage of PPG samples in saline water is a key factor affecting the efficiency of the water conformance process. In this study, an efficient series of PPGs were synthesized and their swelling beh...

Birdsey, T. J., R. D. H. Boyd, C. P. Sibley, and S. L. Greenwood. Effect of hyposmotic challenge on microvillous membrane potential in isolated human placental villi. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R1479–R1488, 1999.—This study examined the effect of hyposmotic solutions on the syncytiotrophoblast microvillous membrane potential (Em) in mature intermediate villi...

The two isozymes of dihydrofolate reductase (Forms 1 and 2) from, a Trimethoprim-resistant strain of Escherichia coli (RT500) were separated and purified to homogeneity using a simple procedure based on differential elution from a Methotrexate affinity column. The complete amino acid sequence of the Form 2 isozyme was determined, and it differs from that of Form 1 in only one position. Residue ...

BACKGROUND Electrophysiological mismatch between host cardiomyocytes and donor cells can directly affect the electrical safety of cardiac cell therapies; however, the ability to study host-donor interactions at the microscopic scale in situ is severely limited. We systematically explored how action potential (AP) differences between cardiomyocytes and other excitable cells modulate vulnerabilit...

PURPOSE To investigate how nitric oxide (NO) modulates short-circuit current (Isc) in isolated porcine ciliary processes. METHODS Isc changes (Ussing-type chamber) induced either by the NO donors SNP or SIN-1, or by the cGMP analogue 8-pCPT-cGMP were assessed. The effect of inhibitors of guanylate cyclase (10 microM ODQ, 100 microM LY83583), protein kinase G (30 microM Rp-8-pCPT-cGMP, 3 micro...
