Steroidogenic compensation and lipid deficiency with enhanced NAD+ salvage in small‐for‐gestational‐age placenta

open access: yesThe FEBS Journal, EarlyView.
Fetal growth restriction is associated with placental metabolic adaptations. In small‐for‐gestational‐age placenta (SGA), cholesterol receptors and steroidogenic enzymes are upregulated, enhancing steroidogenesis. NAD salvage pathway is also increased to support NADP+/NADPH requirements.

Conventional cigarettes, novel heated tobacco products, and self‐reported frequent headache association in Japanese individuals: Insights from the JASTIS study, a Japanese cross‐sectional analysis

open access: yesHeadache: The Journal of Head and Face Pain, EarlyView.
Plain Language Summary Headache is a common health problem, and tobacco products, such as conventional cigarettes and heated tobacco products (HTPs), may be associated with it. Using data from over 23,000 adults in the Japan Society and New Tobacco Internet Survey, we examined the relationships between cigarette and HTP use and self‐reported frequent ...

Schizophrenia and Nicotinic Receptors

Harvard Review of Psychiatry, 1994
Patients with schizophrenia often cannot respond to important features of their environment and filter out irrelevant stimuli. This dysfunction could be related to an underlying defect in inhibition--i.e., the brain's ability to alter its sensitivity to repeated stimuli. One of the neuronal mechanisms responsible for such inhibitory gating involves the

Human neuronal nicotinic receptors

Progress in Neurobiology, 1997
Nicotine is a very widely used drug of abuse, which exerts a number of neurovegetative, behavioural and psychological effects by interacting with neuronal nicotinic acetylcholine receptors (NAChRs). These receptors are distributed widely in human brain and ganglia, and form a family of ACh-gated ion channels of different subtypes, each of which has a ...

The Nicotinic Receptor Genes

Clinical Neuropharmacology, 1991
The causative factor(s) of Alzheimer's disease (AD) are presently unknown. However, it has been shown that the number as well as the fraction of high- to low-affinity nicotine binding sites is altered in patients suffering from this disease. This finding, along with the identification of seven genes which code for nicotinic receptors expressed in the ...

Nicotinic Acetylcholine Receptors

2003
Publisher Summary This chapter deals with nicotinic acetylcholine receptors. Nicotinic acetylcholine receptors (nAChRs) are cholinergic receptors that form ligand-gated ion channels in the plasma membranes of certain neurons and on the postsynaptic side of the neuromuscular junction. As ionotropic receptors, nAChRs are directly linked to ion channels

Nicotinic receptors and schizophrenia

Current Medical Research and Opinion, 2004
The incidence of smoking is very high in non-schizophrenic subjects presenting various psychiatric disorders (35 to 54%). However, the incidence of smoking is extremely high in schizophrenic patients: 80% to 90%, versus 25% to 30% of the general population. Various studies have demonstrated that the use of tobacco transiently restores the schizophrenic

Nicotine, Brain Nicotinic Receptors, and Neuropsychiatric Disorders

Archives of Medical Research, 2000
Neuronal nicotinic acetylcholine receptors (nAChRs) represent a large family of ligand-gated cation channels with diverse structures and properties. In contrast to the muscular nAChRs, the physiological functions of neuronal nAChRs are not well defined to date.

Presynaptic nicotinic ACh receptors

Trends in Neurosciences, 1997
Nicotinic ACh (nACh) receptors in the CNS are composed of a diverse array of subunits and have a range of pharmacological properties. However, despite the fact that they are ligand-gated cation channels, their physiological functions have not been determined.
