Chemical changes underlying Dupuytren's contracture.

Role of changes in [Ca2+]i in energy deprivation contracture.

Mechanisms of energy deprivation contracture were investigated in cultured chick embryo ventricular cells. In the presence of zero-extracellular-Na+, (choline chloride substitution)-nominal-zero-Ca2+ [( Ca2+] approximately 5 microM), exposure of ventricular cells to 1 mM cyanide (CN) and 20 mM 2-deoxyglucose (2-DG)-zero-glucose solution resulted in the development of a contracture (video motion...

Role of Changes in [Ca]; in Energy Deprivation Contracture

Mechanisms of energy deprivation contracture were investigated in cultured chick embryo ventricular cells. In the presence of zero-extracellular-Na* (choline chloride substitution)-nominal-zero-Ca ([Ca] ~ 5 fiM), exposure of ventricular cells to 1 mM cyanide (CN) and 20 mM 2-deoxyglucose (2-DG)-zero-glucose solution resulted in the development of a contracture (video motion detector) in 5.9 ±0....

The Chemical Interactions Underlying Tomato Flavor Preferences

Although human perception of food flavors involves integration of multiple sensory inputs, the most salient sensations are taste and olfaction. Ortho- and retronasal olfaction are particularly crucial to flavor because they provide the qualitative diversity so important to identify safe versus dangerous foods. Historically, flavor research has prioritized aroma volatiles present at levels excee...

Electrocardiographic changes underlying central nervous system damage.

We present the case of a 58 year-old woman with dyslipidemia, ex-smoker, with no known history of heart problems, agnosed with oat-cell lung carcinoma two years earlier. She perienced extreme fatigue and inability to make fine moveents for 10 days and sought emergency care. A cerebral mputed tomography (CT) revealed a space-occupying lesion the right frontal region, indicative of metastasis. A ...
