Further Characterization of Dopamine Release by Permeabilized PC 12 Cells [PDF]

, 1987
Rat pheochromocytoma cells (PC 12) permeabilized with staphylococcal α-toxin release [3H]dopamine after addition of micromolar Ca2+. This does not require additional Mg2+-ATP (in contrast to bovine adrenal medullary chromaffin cells).

Undetected cases after implementation of first‐trimester anomaly scan in low‐risk population: insights from the IMITAS study

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 1, Page 27-33, January 2026.
ABSTRACT Objective To assess the effectiveness of the first‐trimester anomaly scan (FTAS) performed as part of a centrally steered national screening program in The Netherlands by investigating false‐negative cases with a fetal structural anomaly that was not detected at the FTAS.

Cryptic signals: substomatal architecture influences stomatal responses to red light and CO2

New Phytologist, Volume 249, Issue 1, Page 181-188, January 2026.
Summary The mesophyll provides a critical signal for stomatal responses to red light (RL) and CO2 in angiosperms. By contrast, the stomatal response to blue light (BL) is largely guard cell‐specific. It is not known whether substomatal or mesophyll anatomy influences the effectiveness of the mesophyll signal driving stomatal responses to RL and CO2 ...

Ca2+-Stimulated Catecholamine Release from alpha-Toxin Permeabilized PC12 Cells [PDF]

, 1987
Two possible cellular pathways of catecholamines from the chromaffin vesicles of PC 12 cells to the surrounding medium are explored in this study. The direct one circumventing the cytoplasm can be activated in a-toxin-permeabilized cells with micromolar ...
