Cyanamide Potentiates the Ethanol-Induced Impairment of Receptor-Mediated Endocytosis in a Recombinant Hepatic Cell Line Expressing Alcohol Dehydrogenase Activity

International Journal of Hepatology, 2012
Ethanol administration has been shown to alter receptor-mediated endocytosis in the liver. We have developed a recombinant hepatic cell line stably transfected with murine alcohol dehydrogenase cDNA to serve as an in vitro model to investigate these ...

The effect of hydrogen cyanamide on bud break and yield of kiwifruit in Northwest-Portugal [PDF]

, 2003
Kiwifruit (Actinidia deliciosa cv. Hayward) was introduced into Northwest Portugal at the early 1970's increasing its importance up to date. The main objective of orchard management is to find out the cultural techniques suitable for the region, in order

Der Ursprung der Bausteine des Lebens auf der Erde im Hadaikum

Angewandte Chemie, Volume 137, Issue 42, October 13, 2025.
Der Ursprung des Lebens im Hadaikum erforderte die Bildung von Aminosäuren und Nukleosiden als Schlüsselmoleküle des Lebens. In einer oft postulierten stark reduzierenden Atmosphäre bilden sich HCN und seine Derivate robust als plausible Ausgangsstoffe. Aber HCN bildet sich nicht in der schwach reduzierenden Atmosphäre des Hadaikums.

Synthesis, Crystal Structure, and Chemical-Bonding Analysis of BaZn(NCN)2

Inorganics, 2017
The ternary carbodiimide BaZn(NCN)2 was prepared by a solid-state metathesis reaction between BaF2, ZnF2, and Li2NCN in a 1:1:2 molar ratio, and its crystal structure was determined from Rietveld refinement of X-ray data.

Reduction in Central H2O2 Levels Prevents Voluntary Ethanol Intake in Mice: A Role for the Brain Catalase- H2O2 System in Alcohol Binge Drinking [PDF]

, 2013
Background: Hydrogen peroxide (H2O2) is the cosubstrate used by the enzyme catalase to form Compound I (the catalase-H2O2 system), which is the major pathway for the conversion of ethanol (EtOH) into acetaldehyde in the brain.

Cytotoxicity of Atropisomeric [1,1′‐Binaphthalene]‐2,2′‐Diamines (BINAM) and Analogs in Human Cancer Cells: Enantioselectivity, Structure–Activity Relationships, and Mechanism

ChemMedChem, Volume 20, Issue 19, October 6, 2025.
It is reported for the first time that atropisomeric (R)‐[1,1′‐binaphthalene]‐2,2′‐diamine (R‐BINAM, 1(R)), but not (S)‐[1,1′‐binaphthalene]‐2,2′‐diamine (S‐BINAM, 1(S)), is a moderately potent spindle poison, causing antiproliferation, depolymerization of microtubules, multipolar spindles, pericentriolar material (PCM) fragmentation, mitotic ...
