Structure-Function Studies of Nicotinic Acetylcholine Receptors Using Unnatural Amino Acids [PDF]

, 2012
This dissertation primarily describes structure-function studies of the nicotinic acetylcholine receptors (nAChRs). These studies use a combination of unnatural amino acid mutagenesis and electrophysiology to determine the specific molecular interactions

Differing time dependencies of object recognition memory impairments produced by nicotinic and muscarinic cholinergic antagonism in perirhinal cortex [PDF]

, 2011
The roles of muscarinic and nicotinic cholinergic receptors in perirhinal cortex in object recognition memory were compared. Rats' discrimination of a novel object preference test (NOP) test was measured after either systemic or local infusion into the ...

Scientific Opinion on the safety and efficacy of niacin (nicotinic acid and nicotinamide) as a feed additive for all animal species based on a dossier submitted by Lonza Benelux BV [PDF]

EFSA Journal, 2012
<p>The term ‘niacin’ is used as a generic description of nicotinic acid and nicotinamide with pyridine as the basic structure. Nicotinic acid and nicotinamide function mainly as precursors of the co-enzymes NAD and NADP.

Effect of Nicotinic Acid on Sperm Characteristic and Oocyte Development after In Vitro Fertilization using Cryopreserved Boar Semen

Journal of Animal Reproduction and Biotechnology, 2015
The objective of this study was to investigate the efficiency of nicotinic acid on sperm cryosurvival and fertilization ability in frozen-thawed boar semen. Boar semen was collected by glove-hand method and was frozen using freezing solution treated to 0,

Cloning and characterization of the hamster and guinea pig nicotinic acid receptors

Journal of Lipid Research, 2007
In this study, we present the identification and characterization of hamster and guinea pig nicotinic acid receptors. The hamster receptor shares ∼80–90% identity with the nucleotide and amino acid sequences of human, mouse, and rat receptors. The guinea

The influence of exogenous growth regulators on the cannabinoid content and the main selection traits of hemp (Cannabis sativa L. ssp. Sativa) [PDF]

Journal of Agricultural Sciences (Belgrade), 2022
Hemp (Cannabis sativa L.) is a species sensitive to the influence of exogenous growth regulators, both in the treatment of vegetative plant tissues and in vitro culture. 1-naphthylacetic acid, indole-3-acetic acid, 2,4-dichlorophenoxyacetic acid, kinetin,

The plasma free fatty acid rebound induced by nicotinic acid

Journal of Lipid Research, 1967
The time course of the nicotinic acid-induced changes in levels of plasma free fatty acids (FFA) was examined. The plasma FFA response of fasted dogs to graded doses of nicotinic acid was shown to be biphasic: an initial depression of the level of plasma
