Potential-dependent action ofAnemonia sulcata toxins III and IV on sodium channels in crayfish giant axons
Effects of toxins III and IV (ATX III and IV) from the sea anemoneAnemonia sulcata on the Na current of crayfish giant axons were studied. Both toxins slowed the inactivation of Na channels, producing a maintaine...

Pinacidil activates the ATP-sensitive K+ channel in inside-out and cell-attached patch membranes of guinea-pig ventricular myocytes
Patch-clamp techniques were used to study the effects of pinacidil on the adenosine-5′-triphosphate (ATP)-sensitive K+ channel current in guinea-pig ventricular myocytes. In inside-out patches, the ATP-sensitive ...

Stage-specific gametocytocidal effect in vitro of the antimalaria drug qinghaosu onPlasmodium falciparum
Qinghaosu, an anti-malaria drug, has been found to kill not only asexual blood stages but also the early stages of gametocytes ofPlasmodium falciparum. The effect of qinghaosu in vitro depends on the concentratio...

Stress protein synthesis by crayfish CNS tissue in vitro
Some crustacean axons remain functional for months after injury. This unusual property may require stress proteins synthesized by those neurons or provided to them by glial cells. To begin to explore this hypo...

Dietary retinol: prevention or promotion of carcinogenesis in humans?
A number of epidemiologic studies have found that ‘vitamin A’ is associated with a reduced risk for human cancers. Dietary vitamin A indices reflect intake of several compounds in the diet including retinol an...

Aromatic aldehydes and aromatic ketones open ATP-sensitive K+ channels in guinea-pig ventricular myocytes
Patch-clamp techniques were used to study the effects of three carbonyl compounds, 3,4-dihydroxy-benzaldehyde, 2,3-dihydroxybenzaldehyde, and 2,4-dihydroxy-acetophenone, on the adenosine-5′-triphosphate(ATP)-s...

Oocyte selection: a new model for the maternal-age dependence of Down syndrome
Previously proposed mechanisms for Down syndrome (trisomy 21) have generally invoked a progressive increase in meiotic nondisjunction to explain maternal-age dependence, but models of this sort have failed to ...
