Hess and Rockland [Hess and Rockland (1983) Brain Res. 289, 322-325] proposed that the distribution of acetylcholinesterase within the lateral geniculate nucleus might correlate with the daily activity patterns shown by primates. In diurnal primates, the magnocellular laminae show a greater acetylcholinesterase reaction product. In nocturnal primates, the parvocellular laminae are more heavily ...

infertility can be caused by an unexplained reduction in semen quality in males who present asnormal on physical examination and endocrine testing. there is some evidence that aberrantmetabolism of micronutrients such as choline may play a causative role in male factorinfertility. choline is a crucial factor in the regulation of sperm membrane structure andmotility, and this nutrient plays an i...

Neuroprotective effect of deprenyl on motoneurons of spinal cord after axotomy of peripheral nerves such as sciatic has been well established. Deprenyl is an inhibitor of monoamine oxidase type-B (MAO-B). The main function of this agent is the release of neurotransmitters from pre-synaptic terminals. Acetylcholine is a neurotransmitter that is synthesized by choline acetyltransferase (ChAT) and...

placed on the oxidation of choline to betaine via betaine aldehyde which is catalysed by the choline oxidase system. Recent research has indicated that this pathway may indeed be very important for the scavenging of methyl groups from choline 12 I. T h e catabolism of betaine produces one-carbon fragments ;IS ;I result of the sequential demethylation o f betaine to form glycine. T h e first ste...

α-amino nitriles are synthesized in a one-pot, three-component coupling of aldehydes (or ketones), aniline, and trimethylsilyl cyanide using a catalytic amount of choline chloride.2zncl2 as a bio lewis acidic ionic liquid. mild lewis acidic characteristic of this ionic liquid allows efficient synthesis of α-amino nitriles from acid sensitive aldehydes.
