Nicotine
Nicotine is highly toxic alkaloid. It is the prototypical agonist at nicotinic cholinergic receptors where it dramatically stimulates neurons and ultimately blocks synaptic transmission. Nicotine is also important medically because of its presence in tobacco smoke.
Nicotinic Agonists
Drugs that bind to and activate nicotinic cholinergic receptors (RECEPTORS, NICOTINIC). Nicotinic agonists act at postganglionic nicotinic receptors, at neuroeffector junctions in the peripheral nervous system, and at nicotinic receptors in the central nervous system. Agents that function as neuromuscular depolarizing blocking agents are included here because they activate nicotinic receptors, although they are used clinically to block nicotinic transmission.
Tobacco Use Disorder
Tobacco used to the detriment of a person's health or social functioning. Tobacco dependence is included.
Ganglionic Stimulants
Agents that mimic neural transmission by stimulation of the nicotinic receptors on postganglionic autonomic neurons. Drugs that indirectly augment ganglionic transmission by increasing the release or slowing the breakdown of acetylcholine or by non-nicotinic effects on postganglionic neurons are not included here nor are the nonspecific cholinergic agonists.
Receptors, Nicotinic
One of the two major classes of cholinergic receptors. Nicotinic receptors were originally distinguished by their preference for NICOTINE over MUSCARINE. They are generally divided into muscle-type and neuronal-type (previously ganglionic) based on pharmacology, and subunit composition of the receptors.
Mecamylamine
A nicotinic antagonist that is well absorbed from the gastrointestinal tract and crosses the blood-brain barrier. Mecamylamine has been used as a ganglionic blocker in treating hypertension, but, like most ganglionic blockers, is more often used now as a research tool.
Cotinine
The N-glucuronide conjugate of cotinine is a major urinary metabolite of NICOTINE. It thus serves as a biomarker of exposure to tobacco SMOKING. It has CNS stimulating properties.
Nicotinic Antagonists
Drugs that bind to nicotinic cholinergic receptors (RECEPTORS, NICOTINIC) and block the actions of acetylcholine or cholinergic agonists. Nicotinic antagonists block synaptic transmission at autonomic ganglia, the skeletal neuromuscular junction, and at central nervous system nicotinic synapses.
Chewing Gum
A preparation of chicle, sometimes mixed with other plastic substances, sweetened and flavored. It is masticated usually for pleasure as a candy substitute but it sometimes acts as a vehicle for the administration of medication.

Conditioning, Operant
Learning situations in which the sequence responses of the subject are instrumental in producing reinforcement. When the correct response occurs, which involves the selection from among a repertoire of responses, the subject is immediately reinforced.
Rats, Sprague-Dawley
A strain of albino rat used widely for experimental purposes because of its calmness and ease of handling. It was developed by the Sprague-Dawley Animal Company.

Reinforcement (Psychology)
The strengthening of a conditioned response.
Carbon Monoxide
Carbon monoxide (CO). A poisonous colorless, odorless, tasteless gas. It combines with hemoglobin to form carboxyhemoglobin, which has no oxygen carrying capacity.

The observable response an animal makes to any situation.
Self Stimulation
Stimulation of the brain, which is self-administered. The stimulation may result in negative or positive reinforcement.
Hexamethonium
A nicotinic cholinergic antagonist often referred to as the prototypical ganglionic blocker. It is poorly absorbed from the gastrointestinal tract and does not cross the blood-brain barrier. It has been used for a variety of therapeutic purposes including hypertension but, like the other ganglionic blockers, it has been replaced by more specific drugs for most purposes, although it is widely used a research tool.
Dopamine
One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action.
Benzazepines
Compounds with BENZENE fused to AZEPINES.
Bungarotoxins
Neurotoxic proteins from the venom of the banded or Formosan krait (Bungarus multicinctus, an elapid snake). alpha-Bungarotoxin blocks nicotinic acetylcholine receptors and has been used to isolate and study them; beta- and gamma-bungarotoxins act presynaptically causing acetylcholine release and depletion. Both alpha and beta forms have been characterized, the alpha being similar to the large, long or Type II neurotoxins from other elapid venoms.

(S)-(-)-Cotinine, the major brain metabolite of nicotine, stimulates nicotinic receptors to evoke [3H]dopamine release from rat striatal slices in a calcium-dependent manner. (1/3904)

Cotinine, a major peripheral metabolite of nicotine, has recently been shown to be the most abundant metabolite in rat brain after peripheral nicotine administration. However, little attention has been focused on the contribution of cotinine to the pharmacological effects of nicotine exposure in either animals or humans. The present study determined the concentration-response relationship for (S)-(-)-cotinine-evoked 3H overflow from superfused rat striatal slices preloaded with [3H]dopamine ([3H]DA) and whether this response was mediated by nicotinic receptor stimulation. (S)-(-)-Cotinine (1 microM to 3 mM) evoked 3H overflow from [3H]DA-preloaded rat striatal slices in a concentration-dependent manner with an EC50 value of 30 microM, indicating a lower potency than either (S)-(-)-nicotine or the active nicotine metabolite, (S)-(-)-nornicotine. As reported for (S)-(-)-nicotine and (S)-(-)-nornicotine, desensitization to the effect of (S)-(-)-cotinine was observed. The classic nicotinic receptor antagonists mecamylamine and dihydro-beta-erythroidine inhibited the response to (S)-(-)-cotinine (1-100 microM). Additionally, 3H overflow evoked by (S)-(-)-cotinine (10-1000 microM) was inhibited by superfusion with a low calcium buffer. Interestingly, over the same concentration range, (S)-(-)-cotinine did not inhibit [3H]DA uptake into striatal synaptosomes. These results demonstrate that (S)-(-)-cotinine, a constituent of tobacco products and the major metabolite of nicotine, stimulates nicotinic receptors to evoke the release of DA in a calcium-dependent manner from superfused rat striatal slices. Thus, (S)-(-)-cotinine likely contributes to the neuropharmacological effects of nicotine and tobacco use.  (+info)

Neurogenic vasodilatation of canine isolated small labial arteries. (2/3904)

Mechanisms underlying vasodilatation to nerve stimulation by electrical pulses and nicotine were analyzed in isolated canine small labial arteries. Transmural electrical stimulation (5 and 20 Hz) produced a contraction followed by a relaxation in labial arterial strips denuded of the endothelium, partially contracted with prostaglandin F2alpha. The contraction was abolished by prazosin or combined treatment with alpha, beta-methylene ATP. In the treated strips, neurogenic relaxation was abolished by NG-nitro-L-arginine (L-NA), a nitric oxide (NO) synthase inhibitor, and restored by L-arginine. The D-enantiomers were without effect. Nicotine (10(-4) M) also relaxed the arteries, in which the contractile response was abolished by prazosin and alpha, beta-methylene ATP. The relaxant response was attenuated but not abolished by L-NA; the inhibition was reversed by L-arginine. The remaining relaxation by nicotine was abolished by calcitonin gene-related peptide (CGRP)-[8 to 37], a CGRP1 receptor antagonist. Relaxations elicited by a lower concentration of nicotine (2 x 10(-5) M) sufficient to produce similar magnitudes of response to those induced by 5-Hz electrical nerve stimulation were also inhibited partially by L-NA. Histochemical study with the NADPH-diaphorase method demonstrated positively stained nerve fibers and bundles in the arterial wall, suggesting the presence of neuronal NO synthase. It is concluded that the relaxation induced by electrical nerve stimulation of small labial arteries is mediated exclusively by NO synthesized from L-arginine in nerve terminals, whereas nicotine in the concentrations used evokes relaxations by a mediation of nerve-derived NO and also CGRP, possibly from sensory nerves. The reason why nicotine but not electrical pulses stimulates sensory nerves and elicits vasorelaxation remains unsolved.  (+info)

Acquisition of nicotine discrimination and discriminative stimulus effects of nicotine in rats chronically exposed to caffeine. (3/3904)

Caffeine and nicotine are the main psychoactive ingredients of coffee and tobacco, with a high frequency of concurrent use in humans. This study examined the effects of chronic caffeine exposure on 1) rates of acquisition of a nicotine discrimination (0.1 or 0.4 mg/kg, s.c., training doses) and 2) the pharmacological characteristics of the established nicotine discrimination in male Sprague-Dawley rats. Once rats learned to lever-press reliably under a fixed ratio of 10 schedule for food pellets, they were randomly divided into two groups; 12 animals were maintained continuously on caffeine added to the drinking water (3 mg/ml) and another 12 control rats continued to drink tap water. In each group of water- and caffeine-drinking rats, there were six rats trained to discriminate 0.1 mg/kg of nicotine from saline and six rats trained to discriminate 0.4 mg/kg of nicotine from saline. Regardless of the training dose of nicotine, both water- and caffeine-drinking groups required a comparable number of training sessions to attain reliable stimulus control, although there was a trend for a slower acquisition in the caffeine-drinking group trained with 0.1 mg/kg of nicotine. Tests for generalization to different doses of nicotine revealed no significant differences in potency of nicotine between water- and caffeine-drinking groups. The nicotinic-receptor antagonist mecamylamine blocked the discriminative effects of 0.1 and 0.4 mg/kg nicotine with comparable potency and efficacy in water- and caffeine-drinking groups. There was a dose-related generalization to both the 0.1 and 0.4 mg/kg nicotine cue (maximum average of 51-83%) in water-drinking rats after i.p. treatment with d-amphetamine, cocaine, the selective dopamine uptake inhibitor GBR-12909, apomorphine, and the selective dopamine D1 receptor agonist SKF-82958, but not in caffeine-drinking rats (0-22%). There was no generalization to the nicotine cues after i.p. treatment with caffeine or the selective D2 (NPA) and D3 (PD 128,907) dopamine-receptor agonists in water- and caffeine-drinking rats. The dopamine-release inhibitor CGS 10746B reduced the discriminative effects of 0.4 mg/kg nicotine in water-drinking rats, but not in caffeine-drinking rats. There was no evidence of development of tolerance or sensitization to nicotine's effects throughout the study. In conclusion, chronic caffeine exposure (average, 135 mg/kg/day) did not affect the rate of acquisition of the nicotine discrimination, but it did reduce the dopaminergic component of the nicotine-discriminative cue. The reduction of the dopaminergic component of the nicotine cue was permanent, as this effect was still evident after the caffeine solution was replaced with water in caffeine-drinking rats. That nicotine could reliably serve as a discriminative stimulus in the absence of the dopaminergic component of its discriminative cue may differentiate nicotine from "classical dopaminergic" drugs of abuse such as cocaine and amphetamine.  (+info)

A controlled trial of sustained-release bupropion, a nicotine patch, or both for smoking cessation. (4/3904)

BACKGROUND AND METHODS: Use of nicotine-replacement therapies and the antidepressant bupropion helps people stop smoking. We conducted a double-blind, placebo-controlled comparison of sustained-release bupropion (244 subjects), a nicotine patch (244 subjects), bupropion and a nicotine patch (245 subjects), and placebo (160 subjects) for smoking cessation. Smokers with clinical depression were excluded. Treatment consisted of nine weeks of bupropion (150 mg a day for the first three days, and then 150 mg twice daily) or placebo, as well as eight weeks of nicotine-patch therapy (21 mg per day during weeks 2 through 7, 14 mg per day during week 8, and 7 mg per day during week 9) or placebo. The target day for quitting smoking was usually day 8. RESULTS: The abstinence rates at 12 months were 15.6 percent in the placebo group, as compared with 16.4 percent in the nicotine-patch group, 30.3 percent in the bupropion group (P<0.001), and 35.5 percent in the group given bupropion and the nicotine patch (P<0.001). By week 7, subjects in the placebo group had gained an average of 2.1 kg, as compared with a gain of 1.6 kg in the nicotine-patch group, a gain of 1.7 kg in the bupropion group, and a gain of 1.1 kg in the combined-treatment group (P<0.05). Weight gain at seven weeks was significantly less in the combined-treatment group than in the bupropion group and the placebo group (P<0.05 for both comparisons). A total of 311 subjects (34.8 percent) discontinued one or both medications. Seventy-nine subjects stopped treatment because of adverse events: 6 in the placebo group (3.8 percent), 16 in the nicotine-patch group (6.6 percent), 29 in the bupropion group (11.9 percent), and 28 in the combined-treatment group (11.4 percent). The most common adverse events were insomnia and headache. CONCLUSIONS: Treatment with sustained-release bupropion alone or in combination with a nicotine patch resulted in significantly higher long-term rates of smoking cessation than use of either the nicotine patch alone or placebo. Abstinence rates were higher with combination therapy than with bupropion alone, but the difference was not statistically significant.  (+info)

Higher dosage nicotine patches increase one-year smoking cessation rates: results from the European CEASE trial. Collaborative European Anti-Smoking Evaluation. European Respiratory Society. (5/3904)

The Collaborative European Anti-Smoking Evaluation (CEASE) was a European multicentre, randomized, double-blind placebo controlled smoking cessation study. The objectives were to determine whether higher dosage and longer duration of nicotine patch therapy would increase the success rate. Thirty-six chest clinics enrolled a total of 3,575 smokers. Subjects were allocated to one of five treatment arms: placebo and either standard or higher dose nicotine patches (15 mg and 25 mg daily) each given for 8 or 22 weeks with adjunctive moderately intensive support. The 12 month sustained success rates were: 25 mg patch for 22 weeks (L-25), 15.4%; 25 mg patch for 8 weeks (S-25), 15.9%; 15 mg patch for 22 weeks (L-15), 13.7%; 15 mg patch for 8 weeks (S-15), 11.7%; and placebo (P-0) 9.9% (placebo versus 15 mg, p<0.05; 25 mg versus 15 mg, p<0.03; 25 mg versus placebo, p<0.001, Chi-squared test). There was no significant difference in success rate between the two active treatment durations. Of the first week abstainers (n=1,698), 25.1% achieved success at 12 months as opposed to first week smokers, 2.7% of 1,877 subjects (p< 0.001). In summary, a higher than standard dose of nicotine patch was associated with an increase in the long-term success in smoking cessation but continuation of treatment beyond 8-12 weeks did not increase the success rates.  (+info)

Nicotine increases plasminogen activator inhibitor-1 production by human brain endothelial cells via protein kinase C-associated pathway. (6/3904)

BACKGROUND AND PURPOSE: Smoking both increases stroke risk and reduces the risk of thrombolysis-associated intracerebral hemorrhage. Plasminogen activator inhibitor-1 (PAI-1) is a major regulator of fibrinolysis; elevation of PAI-1 is associated with an increased risk of thrombotic disorders. We studied the effect of nicotine, an important constituent of cigarette smoke, on PAI-1 production by human brain endothelial cells. METHODS: Adult human central nervous system endothelial cells (CNS-EC) were used for tissue culture experiments. We analyzed culture supernatant for PAI-1 protein and measured PAI-1 mRNA (by Northern blot analysis) and protein kinase C (PK-C) activity. RESULTS: Nicotine at 100 nmol/L increased PAI-1 protein production and mRNA expression by CNS-EC. After 72 hours of exposure to nicotine, the concentration of secreted PAI-1 in the cell supernatant was increased 1.90+/-0.2 fold compared with untreated cells. PAI-1 mRNA also increased approximately twofold. Inhibition of PK-C completely abolished this effect. Nicotine had no effect on the concentration of tissue plasminogen activator. CONCLUSIONS: Nicotine increases brain endothelial cell PAI-1 mRNA expression and protein production via PK-C-dependent pathway. These findings provide new insights into why smoking may be associated with predisposition to thrombosis and inversely associated with intracerebral hemorrhage after therapeutic tissue plasminogen activator therapy.  (+info)

Nicotine-modified postinfarction left ventricular remodeling. (7/3904)

Cigarette smoking has been noted to impair wound healing in tissues such as skin, bone, and gut. This study was designed to examine whether nicotine adversely affects postinfarction cardiac wound healing and remodeling in an experimental model of myocardial infarction. For this purpose, two groups of rats were studied. The control group received a simple bandage, and the nicotine group had a section (1.75 mg/day) of a nicotine patch attached on their backs. After a 7-day treatment period, an anterior wall infarction was induced. A bandage-free 7-day healing period followed, after which hearts were isolated for mechanical tests. Nicotine-treated rats developed significantly enlarged left ventricles with thin, infarcted walls and a rightward shift in the passive pressure-volume relationship. Pressure-strain analysis also indicated possible changes in the material properties of the wound for nicotine-treated rats. In conclusion, nicotine has significant adverse effects on postinfarction healing and left ventricular remodeling. These observations have important clinical implications because of the enhanced risk for development of heart failure.  (+info)

Metabolites of a tobacco-specific carcinogen in urine from newborns. (8/3904)

BACKGROUND: Cigarette smoking during pregnancy can result in fetal exposure to carcinogens that are transferred from the mother via the placenta, but little information is available on fetal uptake of such compounds. We analyzed samples of the first urine from newborns whose mothers did or did not smoke cigarettes for the presence of metabolites of the potent tobacco-specific transplacental carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK). METHODS: The urine was collected and analyzed for two metabolites of NNK, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) and its glucuronide (NNAL-Gluc). Gas chromatography and nitrosamine-selective detection, with confirmation by mass spectrometry, were used in the analyses, which were performed without knowledge of the origin of the urine samples. RESULTS: NNAL-Gluc was detected in 22 (71%) of 31 urine samples from newborns of mothers who smoked; NNAL was detected in four of these 31 urine samples. Neither compound was detected in the 17 urine samples from newborns of mothers who did not smoke. The arithmetic mean level of NNAL plus NNAL-Gluc in the 27 newborns of smokers for which both analytes were quantified was 0.14 (95% confidence interval [CI] = 0.083-0.200) pmol/mL. The levels of NNAL plus NNAL-Gluc in the urine from these babies were statistically significantly higher than those in the urine from newborns of nonsmoking mothers (geometric means = 0.062 [95% CI = 0.035-0.110] and 0.010 [considered as not detected; no confidence interval], respectively; two-sided P<.001). NNAL plus NNAL-Gluc levels in the 18 positive urine samples in which both analytes were quantified ranged from 0.045 to 0.400 pmol/mL, with an arithmetic mean level of 0.20 (95% CI = 0.14-0.26) pmol/mL, about 5%-10% of the levels of these compounds detected in the urine from adult smokers. CONCLUSIONS: Two metabolites of the tobacco-specific transplacental carcinogen NNK can be detected in the urine from newborns of mothers who smoked cigarettes during pregnancy.  (+info)

Perinatal Nicotine Exposure Increases Vulnerability of Hypoxic-Ischemic Brain Injury in Neonatal Rats | StrokePerinatal Nicotine Exposure Increases Vulnerability of Hypoxic-Ischemic Brain Injury in Neonatal Rats | Stroke
The new findings of the present study are: (1) perinatal nicotine exposure significantly increases brain vulnerability to HI injury in male rat pups, but not in female pups; (2) this heightened vulnerability is associated with sex-specific reprogramming of AT1R and AT2R expression patterns in the developing brain; (3) both AT1R and AT2R are implicated in the pathogenesis of HI brain injury and exhibit the neuroprotective effect in neonatal brains; (4) downregulation of AT2R in the developing brain plays a causal role in nicotine-induced, heightened brain vulnerability to HI injury in neonatal rats; and (5) increased methylation of CpG locus 3 bases upstream of TATA-box at the AT2R promoter is a mechanism of nicotine-mediated AT2R gene repression.. The present finding that perinatal nicotine exposure increased brain HI injury in neonates is novel and suggests a risk factor of maternal cigarette smoking in heightened brain HIE vulnerability in newborns. The nicotine dose used in the present study ...

TY - CHAP. T1 - Influence of prenatal nicotine exposure on development of neurotransmission in central respiratory neurons. AU - Fregosi, Ralph F.. PY - 2008/1/1. Y1 - 2008/1/1. N2 - This chapter considers the influence of prenatal nicotine exposure on the development of neurotransmission in central respiratory neurons. Neonatal mammals that are nicotine exposed in utero show abnormalities in central ventilatory control, such as reduced ventilatory output (1,2), altered breathing pattern (2-4), increased apnea frequency (2,4) and duration (5), delayed arousal in response to hypoxia (6,7), decreased sensitivity to hypoxia (1,4,5,8-11), and diminished capacity for autoresuscitation following severe hypoxic exposure (12,13). Although these findings provide substantial evidence that development of central ventilatory control is altered by prenatal nicotine exposure, the mechanism of nicotines action on respiratory-related neurons has not been identified. Identifying these mechanisms is important ...

TY - JOUR. T1 - Nicotine effects on alertness and spatial attention in non-smokers. AU - Griesar, William S.. AU - Zajdel, Daniel P.. AU - Oken, Barry S.. PY - 2002/7/4. Y1 - 2002/7/4. N2 - Nicotine reportedly improves covert orienting of spatial attention, but enhanced alertness may also play a role. The present study explored nicotine effects on measures of spatial attention and alertness in non-smokers. Nicotine was delivered to 17 non-smokers (data from 12 subjects were analyzed) by a 7-mg transdermal patch (one patch in a low-nicotine condition; two patches in a high-nicotine condition). We examined nicotines effects on spatial attention using a covert orienting task with central, predictive cue stimuli. Nicotine effects on alertness were examined with EEG and subjective questionnaires. Blood was drawn and serum levels of nicotine are reported. Nicotine decreased overall reaction times in the covert orienting task. There was no change in the validity effect, the reaction time difference ...

Project Summary/Abstract The long term goal of this project is to determine the likely health effects in Smokers with Mental Health Conditions (SMHC) of a rule requiring very low nicotine content in cigarettes, in conjunction with availability of nicotine-containing electronic cigarettes (ecigs). This will be tested in a rigorous randomized controlled trial design. We plan to use a comprehensive set of measures of proven validity and reproducibility, including toxicant exposure (urinary NNAL, exhaled CO), addiction (FTND) and mental health (Kessler K6) to assess these effects. This is a prospective parallel-group randomized double-blind, 2-by-2 controlled trial in which 240 current smokers with mental health conditions will be randomized to one of 4 groups: 1) normal nicotine content cigarettes (11mg nicotine content per cigarette, NNCs) and 15mg/mL nicotine ecigs; 2) NNCs and zero mg/mL nicotine ecigs; 3) Very low nicotine content cigarettes (0.2mg nicotine/cigarette, VLNCs) and 15mg/mL ...

Perinatal nicotine exposure induces asthma in second generation offspring | BMC Medicine | Full TextPerinatal nicotine exposure induces asthma in second generation offspring | BMC Medicine | Full Text
By altering specific developmental signaling pathways that are necessary for fetal lung development, perinatal nicotine exposure affects lung growth and differentiation, resulting in the offsprings predisposition to childhood asthma; peroxisome proliferator-activated receptor gamma (PPARγ) agonists can inhibit this effect. However, whether the perinatal nicotine-induced asthma risk is restricted to nicotine-exposed offspring only; whether it can be transmitted to the next generation; and whether PPARγ agonists would have any effect on this process are not known. Time-mated Sprague Dawley rat dams received either placebo or nicotine (1 mg/kg, s.c.), once daily from day 6 of gestation to postnatal day (PND) 21. Following delivery, at PND21, generation 1 (F1) pups were either subjected to pulmonary function tests, or killed to obtain their lungs, tracheas, and gonads to determine the relevant protein markers (mesenchymal contractile proteins), global DNA methylation, histone 3 and 4 acetylation, and for

Background: The U.S. FDA has the authority to limit the nicotine content of cigarettes; however, there are concerns that reduced nicotine cigarettes will be smoked more intensely and, therefore, will increase exposure to toxic chemicals in smoke. This study examined changes in consumer behavior and exposure in response to cigarettes with substantially reduced nicotine content.. Methods: Seventy-two adult smokers completed an unblinded trial of reduced nicotine cigarettes. Participants completed a 7-day baseline period during which they smoked their usual cigarette brand, followed by consecutive 7-day periods smoking cigarettes with progressively lower nicotine levels (0.6, 0.3, and 0.05 mg emission Quest cigarettes). Nicotine dependence and withdrawal, smoking behavior, and biomarkers of exposure were assessed for each 7-day period.. Results: Significant reductions in nicotine intake were observed between usual brand smoking (∼1.2 mg nicotine) and the 0.3 and 0.05 mg nicotine emission ...

Estimation of Nicotine Dose after Low-level Exposure Using Plasma and Urine Nicotine Metabolites | Cancer Epidemiology,...Estimation of Nicotine Dose after Low-level Exposure Using Plasma and Urine Nicotine Metabolites | Cancer Epidemiology,...
We present novel data validating the use of various nicotine metabolite biomarkers in plasma and urine in relation to daily dose of nicotine. We have focused on low-level exposure in nonsmokers as would be most relevant to evaluating nonsmokers exposure to secondhand smoke.. The strongest correlation with nicotine dose was observed for the sum of the four or six of the major nicotine metabolites (Cot + Cot-G + 3HC + 3HC-G, with or without Nic + Nic-G) in a 24-hour urine collection. The correlation coefficient of 0.96 indicates that these biomarker measures account for most of the variance in the estimation of dose. Other combinations of urine metabolites including cotinine and 3HC also correlated exceedingly well with dose of nicotine.. Plasma concentrations of cotinine, 3HC, and the sum of Cot + 3HC were also highly correlated with nicotine dose, but not as strongly as 24-hour urine metabolite measures.. Interestingly, plasma 3HC and the sum of Cot + 3HC in plasma seemed to be more highly ...

Maternal nicotine exposure: Effect on physical development and fine mo by Estelle Lacoste RobinsonMaternal nicotine exposure: Effect on physical development and fine mo by Estelle Lacoste Robinson
The purpose of the present study was to measure the effect of chronic maternal nicotine consumption during gestation only, gestation continuing through lactation, lactation only, and a no-drug control group on physical development, and gross and fine motor coordination of the offspring. To more precisely measure the dose response curve, three dose levels of nicotine (3.0, 2.25, 1.5mg/kg) were administered along with a saline control group. Nicotine was administered via an osmotic minipump. Gravid rats were randomly assigned to one of the four conditions. The pump was implanted on postnatal day 14. The offspring studied were male Sprague-Dawley rats 1 to 22 days old. Half of the pups from each litter were cross fostered to isolate the drug effect prenatally. Maturational parameters were pinna detachment, incisor eruption, and eye opening. Gross motor coordination measures were surface righting, negative geotaxis, swimming ontogeny, and open field. Measures of fine motor coordination were roto rod and

Best Nicotine Salts - Vapor VanityBest Nicotine Salts - Vapor Vanity
Nicotine salt refers to the type of nicotine that is present in tobacco leaves. The normal liquid nicotine that is found in most e-juices is a pure variant, without any extra additives. Nicotine salt, by contrast, contains the nicotine plus other organic compounds that are present in the tobacco plant.. The pure nicotine that is used in most e-juices is also known as freebase nicotine. It is highly volatile which makes it excellent for vaping since it isnt bonded to any other chemicals.. So why are companies beginning to use nicotine salt in their e-juices?. Even though freebase nicotine is generally considered easier to vape, some companies have found that by adding benzoic acid to their nicotine salts that they can get nicotine levels comparable to freebase nicotine with the added benefits of nicotine salts.. What are those benefits?. ...

Low Dose Nicotine Exposure Improves Posterior Spinal Fusion in an In V by John France, Scott D. Daffner et al.Low Dose Nicotine Exposure Improves Posterior Spinal Fusion in an In V by John France, Scott D. Daffner et al.
BACKGROUND CONTEXT: A previous pilot study by our group demonstrated that nicotine administration via transdermal nicotine patch showed consistent serum nicotine levels whereas administration via the more commonly utilized mini-osmotic pump resulted in large variations in serum levels of nicotine of rabbits. In other work, we have previously demonstrated that nicotine delivered via a transdermal patch enhanced posterior spinal fusion rates in rabbits. This is contrary to studies published by other groups where nicotine administration decreased fusion rates.

Chronic Nicotine Treatment Impacts the Regulation of Opioid and Non-opioid Peptides in the Rat Dorsal StriatumChronic Nicotine Treatment Impacts the Regulation of Opioid and Non-opioid Peptides in the Rat Dorsal Striatum
The chronic use of nicotine, the main psychoactive ingredient of tobacco smoking, alters diverse physiological processes and consequently generates physical dependence. To understand the impact of chronic nicotine on neuropeptides, which are potential molecules associated with dependence, we conducted qualitative and quantitative neuropeptidomics on the rat dorsal striatum, an important brain region implicated in the preoccupation/craving phase of drug dependence. We used extensive LC-FT-MS/MS analyses for neuropeptide identification and LC-FT-MS in conjunction with stable isotope addition for relative quantification. The treatment with chronic nicotine for 3 months led to moderate changes in the levels of endogenous dorsal striatum peptides. Five enkephalin opioid peptides were up-regulated, although no change was observed for dynorphin peptides. Specially, nicotine altered levels of nine non-opioid peptides derived from precursors, including somatostatin and cerebellin, which potentially ...

The fetal and postnatal development of binding sites for [3H]nicotine was examined in brain regions of normal rats and rats whose mothers received nicotine injections or infusions, starting before fetal implantation (gestational day 4) and continuing to gestational day 20. The normal ontogenetic pattern of binding indicated a small but detectable concentration of sites during late gestation, and a substantial increase after birth, primarily during the period in which the majority of cholinergic synapses is forming. The adult pattern of regional selectivity of binding capabilities, namely midbrain + brainstem greater than cerebral cortex much greater than cerebellum, was not present at birth, but rather developed over the ensuing 3 weeks postpartum. Fetal exposure to nicotine produced an elevation in binding detectable during the course of drug exposure (gestational day 18), a finding similar to nicotines effects in mature brain. However, examination of the subsequent developmental pattern of ...

Nicotine reinforcement and cognition restored by targeted expression of nicotinic receptors | NatureNicotine reinforcement and cognition restored by targeted expression of nicotinic receptors | Nature
The bad news, nicotine addiction has caused the deaths of millions from smoking-related diseases. The good news, nicotine can enhance cognitive performance. In an attempt to disentangle the brain networks that mediate nicotine reward and relevant cognitive functions, Maskos et al. have developed an injectable lentiviral vector that delivers functional nicotinic acetylcholine receptors to defined regions of the mouse brain. The technique was used to generate mice that express nicotinic receptors exclusively in the midbrain ventral tegmental area, the VTA, which contains dopamine reward neurons and is associated with the response to drugs of abuse. The experiment showed that these receptors in the VTA are sufficient for all behavioural and physiological phenomena associated with nicotine dependence. And they are also involved in the higher brain or cognitive functions in the mouse. Nicotines good and bad sides are, it seems, intimately entangled and originate from a phylogenetically ancient part of

Nicotine poisonings of children continued to rise in 2014Nicotine poisonings of children continued to rise in 2014
The Minnesota Poison Control System saw a 35 percent jump in e-cigarette and e-juice poisonings among children from birth to 5 years old between 2013 and 2014. This marks the second year of significant increases in nicotine poisonings related to e-cigarette products, which can contain fatal levels of nicotine for children.. Today, the Minnesota Department of Health issued a nicotine heath advisory to inform parents about the health dangers of accidental nicotine poisonings and the harms that can result from ongoing nicotine use among teens and among pregnant women. Many people think nicotine is addictive but not necessarily harmful on its own for teens and young adults, and that is not the case, said Minnesota Health Commissioner Dr. Ed Ehlinger. We know there are clear health risks of nicotine exposure for youth.. The nicotine health advisory is based on a summary of the latest research on the health risks of nicotine.

Reducing the nicotine content to make cigarettes less addictive | Tobacco ControlReducing the nicotine content to make cigarettes less addictive | Tobacco Control
A gradual reduction of nicotine levels of cigarettes was proposed by Benowitz and Henningfield in 1994.10 Whereas this proposal envisioned a reduction to non-addicting nicotine dosage levels over a decade or longer, recent research studies using reduced nicotine content cigarettes to aid smoking cessation have raised the possibility that more rapid lowering of nicotine content might be equally or more effective.11 A reduced nicotine cigarette policy would have to apply to all manufactured cigarettes and potentially to tobacco sold for roll-your-own cigarettes, small cigars and perhaps ultimately to all other combustible tobacco products in a particular country.. One of the assumptions implicit in a nicotine reduction strategy is that there is a threshold nicotine exposure that is necessary to produce reinforcing effects and to sustain addiction. It is likely that there is no single threshold that applies to all people. There is considerable individual variability in dose sensitivity to all ...

The Safety of Transdermal Nicotine Immediately Following an Acute Coronary Syndrome - Full Text View - ClinicalTrials.govThe Safety of Transdermal Nicotine Immediately Following an Acute Coronary Syndrome - Full Text View - ClinicalTrials.gov
Continuing to smoke after having a heart attack greatly increases the risk of death and cardiac illness. The nicotine patch is a commonly used pharmacotherapy for smoking cessation and has great potential to help heart attack patients quit smoking. However, due to safety concerns, physicians are often hesitant to prescribe the nicotine patch to patients who have just suffered a heart attack. The STADIA pilot study will assess the feasibility of a large-scale clinical trial investigating safety and efficacy outcomes associated with the nicotine patch immediately following a heart attack. Eligible subjects will be randomized within 48 hours of suffering a heart attack to wear a transdermal nicotine patch on either day 1 or day 2 of the study period. The nicotine patch will deliver nicotine to the patient over the period of 24 hours. Patients will be advised to discuss smoking cessation strategies with their treating physician and subsequent care will be left to the discretion of this physician. ...

Pharmacotherapy provision based on Nicotine Metabolite Ratio (NMR) status (slow/normal metabolism) may improve smoking cessation rates. However, it is unclear whether NMR status is consistent across patient characteristics and current treatment choice. Data come from 1,826 participants attending Stop Smoking Services (SSS) across England in 2012/13. Sociodemographic, mental/physical health, smoking and treatment characteristics (nicotine replacement therapy vs. other pharmacotherapy; group vs. one-to-one behavioural support) were assessed. Salivary nicotine metabolites were measured and NMR (3-hydroxycotinine/cotinine) computed, characterising smokers as slow (NMR,0.31) or normal (NMR≥0.31) metabolisers. Normal metabolisers were older than slow metabolisers (Odds Ratio (OR) =1.49, 95% Confidence Interval (CI) =1.32-1.69) but no other characteristics were associated with NMR status. Overall, predictors accounted for only 7.3% of NMR variance. In adjusted analysis, pharmacotherapy type was not ...

Smoking is a significant public health problem, and there is a great need for research to improve smoking cessation treatment outcomes. The goal of the Pharmacogenetics of Nicotine Addiction Treatment (PNAT) research program is to generate the evidence base to optimize treatment decisions for Individuals who want to quit smoking. During the past 4 years of PNAT1, we have characterized genetic variants altering nicotine pharmacokinetics as well as pharmacodynamic genetic variants influencing response to pharmacotherapies for smoking cessation treatment. We have shown that the CYP2A6 enzyme is critical in the metabolic inactivation of nicotine, and inherited variation in nicotine clearance influences smoking behavior and cessation. With a vision toward translation of our research to practice, we have characterized a genetically-informed biomarker of CYP2A6 activity, specifically the nicotine metabolite ratio (NMR;3hydroxycotinine/cotinine), which reflects both genetic and environmental influences ...

Nicotinic receptors play an important role in modulating the activity of parasympathetic cardiac vagal neurons in the medulla. Previous work has shown nicotine acts via at least three mechanisms to excite brain stem premotor cardiac vagal neurons. Nicotine evokes a direct increase in holding current and facilitates both the frequency and amplitude of glutamatergic neurotransmission to cardiac vagal neurons. This study tests whether these nicotinic receptor-mediated responses are endogenously active, whether α4β2 and α7 nicotinic receptors are involved, and whether prenatal exposure to nicotine alters the magnitude of these responses and the types of nicotinic receptors involved. Application of neostigmine (10 μM) significantly increased the holding current, amplitude, and frequency of miniature excitatory postsynaptic current (mEPSC) glutamatergic events in cardiac vagal neurons. In unexposed animals, the nicotine-evoked facilitation of mEPSC frequency, but not mEPSC amplitude or holding current,

Background:Previous studies have shown that nicotine enhances oxidative DNA damage and leads to increased lipid peroxidation, which affects embryo development. The present study investigated the effect of daily supplementation of gamma-tocotrienol on oocytes of nicotine-treated mice. Material and Method:Immature female mice (18-25 g) were divided into three groups. For 30 days, group A (control group) received saline (0.2 ml/day s.c.), group B nicotine (5 mg/kg/day s.c. in saline), and group C nicotine with gamma-tocotrienol (60 mg/kg/day p.o.). The animals were superovulated following these schedules. Results:Scanning electron microscopy (SEM) showed that the nicotine-treated oocytes appeared nonspherical with rough surface and the zona pellucida (zp) was torn and became irregular. Supplementation with gamma-tocotrienol in the nicotine-treated mice retained the spherical shape of the oocytes with intact zp; however, the surfaces of the oocytes remained irregular and rough.

Another study showed that nicotine boosted cognitive function in older people who didnt have Alzheimers, but were showing signs of age-related mental decline.. Nicotine also seems to protect against Parkinsons disease, in which the death of cells in a small area of the brain results in tremors, impairing movement and as well as cognitive difficulties.

The Nicotine Challenge - NaturalNews.comThe Nicotine Challenge - NaturalNews.com
Natural News) What if you took a break from nicotine and that break lasted forever? Theres really just one major reason you cant right now, and thats because nicotine is immediate relief from the horrible feelings that creep in when the nicotine from your last drag wears off. When was that, 20 minutes ago, 30 minutes ago or an hour? If you smoke 2 packs a day, thats every twenty minutes or less. A pack-a-day smoker lights a new cancer stick about every half-hour, and half-a-pack-a-day equates to a smoke every hour. As for vape addicts, well, they seem to never stop. Maybe because the nicotine doses are lower than most commercial cigarettes, and so its all about repetition and frequency rather than extreme dosage.. Either way, the nicotine hangover is brutal, and every user needs a break sometimes. The question is, can that break be extended indefinitely, to the point where the physical, mental and habitual addiction just melts away, for good? Are you a user, or someone you know? One in ...

Utilization of nicotine nasal spray in smoking cessation | The Journal of the American Osteopathic AssociationUtilization of nicotine nasal spray in smoking cessation | The Journal of the American Osteopathic Association
It is widely accepted that nicotine replacement therapy can help patients to quit smoking. Recent approval by the US Food and Drug Administration of a nicotine nasal spray gives clinicians greater flexibility in choosing the best replacement therapy for a particular patient. Four types of smoking cessation therapy are currently available (gum, patch, nasal spray, and bupropion). These differ with respect to their onset and duration of action, adverse effects, and cost. This article focuses on which patients may benefit most from the use of nicotine nasal spray. Instructions for proper administration and dosing of the nicotine nasal spray are discussed as well as how to taper it appropriately, and how to avoid--and manage--adverse effects.

Altmetric - Mecamylamine (a nicotine antagonist) for smoking cessationAltmetric - Mecamylamine (a nicotine antagonist) for smoking cessation
Mecamylamine is a nicotine antagonist (that is it blocks the effect of nicotine). The rationale for its use in smoking cessation is that it may block the rewarding effect of nicotine and thus reduce the urge to smoke. The objective of this review was to determine the effectiveness of mecamylamine in promoting smoking cessation, either alone or in combination with nicotine replacement therapy. We searched the Cochrane Tobacco Addiction Group trials register. Randomised trials of mecamylamine, either alone or in combination with nicotine replacement therapy, which reported smoking cessation rates at least six months after intervention. We extracted data in duplicate on the type of subjects, the dose and duration of the mecamylamine and nicotine treatments, side-effects of treatment, the outcome measures, method of randomisation, and completeness of follow-up. The main outcome measure was sustained abstinence from smoking (biochemically validated) after at least six months follow-up in patients ...

Long reliance on nicotine gum may cause other health problemsLong reliance on nicotine gum may cause other health problems
Q: After 30 years of smoking, I quit the habit 12 years ago. Since then, Ive been chewing about 15 pieces of nicotine gum every day. Can you tell me how this might be affecting my health? Im in good health overall, but my HDL is still too low despite daily exercise and taking 4,800 milligrams of fish oil daily. A: The good news is that by stopping smoking, youve significantly reduced your risk of heart disease and cancer, especially lung cancer. The not-so-good news is that continued, long-term use of nicotine-replacement therapy could potentially cause other health problems. The purpose of nicotine gum is to deliver small doses of nicotine to your body, which allow you to better manage your withdrawal symptoms and cravings as you quit smoking. When you smoke, you inhale nicotine and more than 4,000 harmful chemicals. More than 60 of those substances are known to cause cancer. Replacing smoking with a pure nicotine alternative, such as nicotine gum, eliminates all those other chemicals, and ...

N2 - Prenatal nicotine exposure impairs normal lung development and leads to diminished pulmonary function after birth. Previous work from our laboratory has demonstrated that nicotine alters lung development by affecting a nonneuronal cholinergic autocrine loop that is expressed in lung. Bronchial epithelial cells (BECs) express choline acetyltransferase, the choline high-affinity transporter and nicotinic acetylcholine (ACh) receptor (nAChR) subunits. We now demonstrate through a combination of morphological and electrophysiological techniques that nicotine affects this autocrine loop by up-regulating and activating cholinergic signaling.

Osteopontin (OPN) is a secreted phospho-protein that confers on cancer cells a migratory phenotype. We have recently shown that nicotine, a risk factor in pancreatic ductal adenocarcinoma (PDA), induces an alpha7-nicotine acetylcholine receptor (α7-nAChR)-mediated increase of OPN in PDA cells. In this study, we tested nicotines effect on the expression of OPN splice variants (OPNa, b, c) in PDA cells. We also analyzed the correlation between patients smoking history with OPN and α7-nAChR levels. RT-PCR and UV-light-illumination of ethidium-bromide staining were used to examine the mRNA expression in tissue and PDA cells treated with or without nicotine (3-300 nM). Localization of total OPN, OPNc and α7-nAChR was analyzed by immunohistochemistry, and their mRNA tissue expression levels were correlated with the patients smoking history. PDA cells expressed varying levels of OPNa, OPNb, and α7-nAChR. Nicotine treatment selectively induced denovo expression of OPNc and increased α7-nAChR expression

Tobacco Addiction | National Institute on Drug Abuse (NIDA)Tobacco Addiction | National Institute on Drug Abuse (NIDA)
Nicotine Replacement Therapy (NRT) A variety of formulations of nicotine replacement therapies (NRTs) now exist, including the transdermal nicotine patch, nicotine spray, nicotine gum, and nicotine lozenges. Because nicotine is the main addictive ingredient in tobacco, the rationale for NRT is that stable low levels of nicotine will prevent withdrawal symptoms-which often drive continued tobacco use-and help keep people motivated to quit. Research shows that combining the patch with another replacement therapy is more effective than a single therapy alone.

Nicotine dependence - WikipediaNicotine dependence - Wikipedia
Pre-existing cognitive and mood disorders may influence the development and maintenance of nicotine dependence.[22] Nicotine is a parasympathomimetic stimulant[11] that binds to and activates nicotinic acetylcholine receptors in the brain,[12] which subsequently causes the release of dopamine and other neurotransmitters, such as norepinephrine, acetylcholine, serotonin, gamma-aminobutyric acid, glutamate, endorphins,[23] and several neuropeptides.[24] Repeated exposure to nicotine can cause an increase in the number of nicotinic receptors, which is believed to be a result of receptor desensitization and subsequent receptor upregulation.[23] This upregulation or increase in the number of nicotinic receptors significantly alters the functioning of the brain reward system.[25] With constant use of nicotine, tolerance occurs at least partially as a result of the development of new nicotinic acetylcholine receptors in the brain.[23] After several months of nicotine abstinence, the number of receptors ...

Screening for Tobacco and Nicotine Use in Pregnancy | Article | NursingCenterScreening for Tobacco and Nicotine Use in Pregnancy | Article | NursingCenter
Tobacco and nicotine use are associated with numerous adverse health effects including miscarriage, preterm birth, low birthweight, placenta previa, placental abruption, cleft lip and palate, and sudden infant death syndrome (SIDS). Babies exposed to secondhand smoke have increased risk of ear infections, asthma complications, and SIDS (Centers for Disease Control and Prevention [CDC], 2016). Prevalence of all forms of nicotine use among pregnant women in the United States is unknown; however, 8.4% of women report smoking at some time during pregnancy (Curtin & Matthews, 2016). Cigarette smoking has declined among adolescents, though use of electronic cigarettes and hookah has increased (CDC), thus screening for new and emerging tobacco products is increasingly important. Familiarity with the many types of tobacco and nicotine should guide screening questions, for example, instead of asking a woman if she smokes cigarettes, nurses might ask, Do you use any type of tobacco or nicotine? or Do ...

Quitting Smoking - Nicotine Patches Vs Hypnosis - Health and Medical EthicsQuitting Smoking - Nicotine Patches Vs Hypnosis - Health and Medical Ethics
I personally gave up smoking last year -after 20 long years of being a smoker. I was extremely lucky that I met Cindy from http://www.cindygalvin.co.uk who uses a method call RTT hypnosis and it worked extremely well for me. However, it seems hypnosis may not work for everyone, and if you are one of those who is not so lucky, another way to give up smoking is by using nicotine patches.. Here is a brief overview of nicotine patches with a detailed list of side effects:. The nicotine patch is a safe and effective method to use in smoking cessation. They are made in several different strengthsusually 21mg, 14 mg, and 7mgand can accommodate the occasional or chain smoker. These patches work by delivering a steady stream of nicotine into your system that curbs your cravings and allows you to gradually lower the dosage until you no longer need them. Each box contains 14 patches and the dosage is recommended depending on how many cigarettes you smoke per day. There are,however, some side effects to be ...

Nicotine replacement therapy in smoking cessation | ThoraxNicotine replacement therapy in smoking cessation | Thorax
Most smokers become nicotine dependent and, when they stop smoking, experience withdrawal symptoms and craving. Nicotine replacement therapy (NRT) reduces these unpleasant symptoms and, theoretically, should decrease the risk of relapse. Smoking cessation is properly defined as validated sustained abstinence from cigarettes and/or other tobacco products for at least 6 months, but preferably for 1 year. This editorial includes evidence only from those studies which have applied such a definition and which have specified their settings and populations.. NRT is available as chewing gum, transdermal patches, sublingual tablets, lozenges, inhalation cartridges and nasal spray. In specialised cessation clinics1-8 and in primary care,9,10 prospective randomised clinical trials have shown that NRT, used as an adjunct to advice and support, results in better cessation rates than does advice and support alone. In the clinics success rates with NRT tend to be higher (11-30%) and more consistent than in ...

E-cigarette-only use and dual-use are emerging behaviours among adolescent nicotine product users which have not yet been sufficiently explored. This study examines the prevalence of, and the factors associated with, nicotine product use in adolescence. The study is a cross-sectional analysis of the 2018 Planet Youth survey completed by 15–16 year olds in the West of Ireland in 2018. The outcome of interest was current nicotine product use, defined as use at least once in the past 30 days. A main effects multinomial logistic regression model was used to examine the association between potential risk and protective factors and nicotine product use. Among 4422 adolescents 22.1% were current nicotine product users, consisting of 5.1% e-cigarette only users, 7.7% conventional cigarette only users, and 9.3% dual-users. For risk factors, the odds of association were weaker for e-cigarette only use compared to conventional cigarette and dual use. Participating in team sport four times/week or more

muscarine and nicotinemuscarine and nicotine
The cholinergic agonists nicotine, muscarine, or arecaidine at increasing 10 − 6, 10 − 5, and 10 − 4 (only muscarine) m concentrations were superfused over the receptive fields for 5 min at 10 min intervals. Nicotinic receptors (nAhRs) are a group of cholinergic receptors that also interact with nicotine in tobacco. Nicotinic and muscarinic receptors are the two main types of cholinergic receptors. Nicotinic receptors are the receptors in which the agonist is nicotine, and are ligand-gated ion channels in which neurotransmission is facilitated. What is the difference between Muscarinic and Nicotinic receptors (apart from there sensitivity to Muscarine and Nicotine)? Nicotine occurs throughout the tobacco plant and especially in the leaves. A large number of physiological functions such as heart rate and force, the release of neurotransmitters, and contraction of smooth muscles are mediated by muscarinic receptors.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Objective: The immune response to an inflammatory stimulus is balanced and or-chestrated by stimulatory and inhibitory factors. After a thermal trauma, this balance is disturbed and an excessive immune reaction with increased production and release of proinflammatory cytokines results. The nicotine-stimulated anti-inflammatory reflex offsets this. The goal of this study was to verify that transdermal administration of nico-tine downregulates proinflammatory cytokine release after burn trauma.

Gas/Particle Partitioning of Ammonia and Nicotine in Mainstream Tobacc by Cai ChenGas/Particle Partitioning of Ammonia and Nicotine in Mainstream Tobacc by Cai Chen
Nicotine is recognized as the tobacco component that is responsible for most if not all of the addictive nature of tobacco. In mainstream tobacco smoke (MTS), the amount of nicotine that is in the free-base form is generally believed to be well correlated with physical â impactâ , â strengthâ , and â harshnessâ of such smoke. There are also reasons to expect that the amount of free-base nicotine may be related to the addictiveness of tobacco smoke. Evidence from previously secret tobacco industry documents indicates that ammonia-producing compounds have been added to cigarette tobacco as â impact boostersâ . Knowledge of the acid/base chemistry of tobacco smoke is required for a proper understanding of the effect of ammonia additives on nicotine chemistry in MTS. The goal of this work was to improve our understanding of this chemistry by studying the interdependent gas/particle (G/P) partitioning of nicotine and ammonia in MTS, including the study of components in MTS that are related

Nornicotine partially substitutes for (+)-amphetamine in a drug discrimination paradigm in rats. | PassportNornicotine partially substitutes for (+)-amphetamine in a drug discrimination paradigm in rats. | Passport
Rats were trained in a two-lever food-reinforced operant task to discriminate (+)-amphetamine (1 mg/kg) from saline. After discrimination training stabilized, test doses of (+)-amphetamine (0.0625-2.0 mg/kg), (-)-nicotine (0.1-1.0 mg/kg), or (-)-nornicotine (1-10 mg/kg) were assessed for their ability to substitute for the (+)-amphetamine training dose during brief test sessions in which food reinforcement was withheld. As expected, as the test dose of (+)-amphetamine increased, there was a dose-related increase in drug-appropriate responding, with both 1 and 2 mg/kg test doses substituting fully for the (+)-amphetamine training dose. Both (-)-nicotine and (-)-nornicotine showed partial substitution (approximately 50% drug-appropriate responding) for the (+)-amphetamine training dose, with (-)-nicotine being more potent than (-)-nornicotine. Rate suppressant effects prevented the assessment of higher doses of (-)-nicotine or (-)-nornicotine. Thus, while (-)-nicotine and (-)-nornicotine share ...

Comparison of Pure Nicotine- and Smokeless Tobacco Extract-induced Tox by Deniz Yildiz, Y. S. Liu et al.Comparison of Pure Nicotine- and Smokeless Tobacco Extract-induced Tox by Deniz Yildiz, Y. S. Liu et al.
The toxicities and oxidative stress-inducing actions of (−)-nicotine and smokeless tobacco extract (STE), containing equivalent amounts of nicotine, were studied. Toxicities were determined by colony formation assays using Chinese hamster ovary (CHO) cells. Results indicated that nicotine is less toxic than smokeless tobacco extract that contained the same amount of nicotine. The generation of reactive oxygen species, following treatment with smokeless tobacco extract and nicotine, was assessed by measurement of changes in glutathione (GSH) and malondialdehyde (MDA) levels. CHO cells (5 × 105 cells/5 ml media) were incubated with 4, 0.8, and 0.08 mg of nicotine and STE containing the same amounts of nicotine. All preparations of smokeless tobacco extract significantly decreased GSH levels and increased MDA generation. However, 0.08 mg of nicotine treatment did not result in a significant change in GSH level, and only 4 mg of nicotine were sufficient to increase MDA generation. Addition of free

Smoking is highly correlated with enhanced likelihood of atherosclerosis by inducing endothelial dysfunction. In endothelial cells, various cell-adhesion molecules including E-selectin, are shown to be upregulated upon exposure to nicotine, the addictive component of tobacco smoke; however, the molecular mechanisms underlying this induction are poorly understood. Here we demonstrate that nicotine-induced E-selectin transcription in human aortic endothelial cells (HAECs) could be significantly blocked by α7-nAChR subunit inhibitor, α-BT, Src-kinase inhibitor, PP2, or siRNAs against Src or β-Arrestin-1 (β-Arr1). Further, chromatin immunoprecipitations show that E-selectin is an E2F1 responsive gene and nicotine stimulation results in increased recruitment of E2F1 on E-selectin promoter. Inhibiting E2F1 activity using RRD-251, a disruptor of the Rb-Raf-1 kinase interaction, could significantly inhibit the nicotine-induced recruitment of E2F1 to the E-selectin promoter as well as E-selectin ...

Abstract: : Purpose: To examine the ability of nicotine, a compound known to be involved in stress-associated immunomodulation, to induce ocular viral shedding in rabbits latently infected with HSV-1 strain McKrae. Methods: New Zealand white rabbits latently infected with HSV-1 were randomly divided into two groups. One group received nicotine by transdermal patch (21 mg/d) for 20 days, the other served as a control. Reactivation data were obtained by detection of infectious virus in tear film collected by daily ocular swabs. The concentration of nicotine (mg/ml) in the serum was determined at 0, 1, 4, 8, 15, and 24 hrs after patch replacement. Results: Rabbits receiving nicotine exhibited a significantly (p=0.00001) higher rate of HSV-1 ocular shedding than controls. Compilation of data from three separate experiments demonstrated that 16.5% (258/1560) of the swabs taken from rabbits treated with nicotine were positive for virus, compared to only 8.3% (53/639) of swabs taken from controls. Peak ...

Cigarette smoking is the foremost modifiable risk factor for adverse pregnancy outcomes. Nicotine is a suspected fetal neuroteratogen. There is concern that nicotine may achieve toxic levels during pregnancy if nicotine replacement therapies are prescribed at doses used in the nonpregnant state. Ten healthy, volunteer, pregnant smokers received infusions of deuterium-labeled nicotine and cotinine during pregnancy and again postpartum. From blood and urine measurements, the following were determined: clearance (renal and nonrenal) of nicotine and cotinine, clearance of nicotine via the cotinine pathway (an indicator of CYP2A6 activity), and daily intake of nicotine from smoking. The clearance of nicotine and cotinine was significantly higher (60 and 140%, respectively), and the half-life of cotinine was much shorter (8.8 versus 16.6 h, P , 0.01) during pregnancy. Although plasma levels of cotinine were lower during pregnancy (119 versus 202 ng/ml, P , 0.05), daily intake of nicotine from smoking ...

Nicotine Addiction | AddictionsNicotine Addiction | Addictions
Nicotine causes chemical and biological changes in the brain. Although it is less dramatic than heroin or cocaine, the strength of the addiction is just as powerful. It is a reinforcing drug, which means that users desire the drug regardless of the damaging effects.The human body builds a tolerance to nicotine and the effect of the drug is reduced over time. As a result, regular smokers can inhale greater amounts of smoke and toxins without showing immediate effects (ie. coughing, nausea).Nicotine is considered addictive because it alters brain functioning and because people use it compulsively. Addiction to nicotine is not immediate - it may take weeks or months to develop ...

Association between nicotinic acetylcholine receptor single nucleotide polymorphisms and smoking cessation. - CLAHRCAssociation between nicotinic acetylcholine receptor single nucleotide polymorphisms and smoking cessation. - CLAHRC
INTRODUCTION: The α4β2 nicotinic receptor is of central importance in tobacco dependence, while the homomeric α7 receptor may also play a role. In this candidate gene study, we examine the association between 8 single nucleotide polymorphisms (SNPs) in genes coding for nicotinic acetylcholine receptor subunits α4 (rs1044396, rs2273504, rs2236196, and rs2273502), α7 (rs2133965 and rs4779969), and β2 (rs2072660 and rs2072661) and smoking abstinence in a cohort of quitters enrolled in a clinical trial of behavioral support. METHODS: Data were obtained from the Patch in Practice study, involving 925 smokers in the United Kingdom. All participants were given an 8-week course of 15 mg of transdermal nicotine replacement therapy and blood was taken for genotyping. RESULTS: Logistic regression analyses assessed the association between each selected SNP and smoking abstinence at 4, 12, 26, and 52 weeks. There were no statistically significant associations with smoking cessation success or nicotine intake

Alcohol use and sleepAlcohol use and sleep
Moderate alcohol consumption 30-60 minutes before bedtime results in disruptions in sleep maintenance and sleep architecture that are mediated by blood alcohol levels.[2] Disruptions in sleep maintenance are most marked once alcohol has been completely metabolized from the body. Under conditions of moderate alcohol consumption where blood alcohol levels average 0.06-0.08% and decrease 0.01-0.02% per hour, an alcohol clearance rate of 4-5 hours would coincide with disruptions in sleep maintenance in the second half of an 8-hour sleep episode.[2] In terms of sleep architecture, moderate doses of alcohol facilitate "rebounds" in rapid eye movement (REM) and stage 1 sleep; following suppression in REM and stage 1 sleep in the first half of an 8-hour sleep episode, REM and stage 1 sleep increase well beyond baseline in the second half. Moderate doses of alcohol also increase slow wave sleep (SWS) in the first half of an 8-hour sleep episode.[2] Enhancements in REM sleep and SWS following moderate ...

Wernicke-Korsakoff syndromeWernicke-Korsakoff syndrome
The vitamin thiamine also referred to as Vitamin B1, is required by three different enzymes to allow for conversion of ingested nutrients into energy. [13] Thiamine can not be produced in the body and must be obtained through diet and supplementation. [23] The duodenum is responsible for absorbing thiamine. The liver can store thiamine for 18 days.[13] Prolonged and frequent consumption of alcohol causes a decreased ability to absorb thiamine in the duodenum. Thiamine deficiency is also related to malnutrition from poor diet, impaired use of thiamine by the cells and impaired storage in the liver. [23]Without thiamine the Kreb's Cycle enzymes pyruvate dehydrogenase complex (PDH) and alpha-ketoglutarate dehydrogenase (alpha-KGDH) are impaired.[13] The impaired functioning of the Kreb's Cycle results in inadequate production of adenosine triphosphate (ATP) or energy for the cells functioning.

HangoverHangover
In addition to ethanol and water, most alcoholic drinks also contain congeners, either as flavoring or as a by-product of fermentation and the wine aging process. While ethanol is by itself sufficient to produce most hangover effects, congeners may potentially aggravate hangover and other residual effects to some extent. Congeners include substances such as amines, amides, acetones, acetaldehydes, polyphenols, methanol, histamines, fusel oil, esters, furfural, and tannins, many but not all of which are toxic.[8] One study in mice indicates that fusel oil may have a mitigating effect on hangover symptoms,[19] while some whiskey congeners such as butanol protect the stomach against gastric mucosal damage in the rat.[20] Different types of alcoholic beverages contain different amounts of congeners. In general, dark liquors have a higher concentration while clear liquors have a lower concentration. Whereas vodka has virtually no more congeners than pure ethanol, bourbon has a total congener content ...

Alcohol intoxicationAlcohol intoxication
Some religious groups permit the consumption of alcohol. Some permit consumption but prohibit intoxication, while others prohibit alcohol consumption altogether. Many Christian denominations such as Catholic, Orthodox, and Lutheran use wine as a part of the Eucharist and permit the drinking of alcohol but consider it sinful to become intoxicated. In the Bible, the Book of Proverbs contains several chapters dealing with the bad effects of drunkenness and warning to stay away from intoxicating beverages. The book of Leviticus tells of Nadab and Abihu, Aaron the Priest's eldest sons, who were killed for serving in the temple after drinking wine, presumably while intoxicated. The book continues to discuss monasticism where drinking wine is prohibited. The story of Samson in the Book of Judges tells of a monk from the tribe of Dan who is prohibited from cutting his hair and drinking wine.[46] Romans 13:13-14,[47] 1 Corinthians 6:9-11, Galatians 5:19-21,[48] and Ephesians 5:18[49] are among a number ...

Drugs in the class of amphetamines, or substituted amphetamines, are known to induce "amphetamine psychosis" typically when chronically abused or used in high doses.[4] In an Australian study of 309 active methamphetamine users, 18% had experienced a clinical level psychosis in the past year.[5] Common amphetamines include cathinone, DOM, ephedrine, MDMA, methamphetamine, and methcathinone though a large number of such compounds have been synthesized. Methylphenidate is sometimes incorrectly included in this class, although is nonetheless still capable of producing stimulant psychosis.. The symptoms of amphetamine psychosis include auditory and visual hallucinations, delusions of persecution, and delusions of reference concurrent with both clear consciousness and prominent extreme agitation.[6][7] A Japanese study of recovery from methamphetamine psychosis reported a 64% recovery rate within 10 days rising to an 82% recovery rate at 30 days after methamphetamine cessation.[8] However it has been ...

When used recreationally benzodiazepines are usually administered orally but sometimes they are taken intranasally or intravenously. Recreational use produces effects similar to alcohol intoxication.[3][4] In tests in pentobarbital trained rhesus monkeys benzodiazepines produced effects similar to barbiturates.[5] In a 1991 study, triazolam had the highest self-administration rate in cocaine trained baboons, among the five benzodiazepines examined: alprazolam, bromazepam, chlordiazepoxide, lorazepam, triazolam.[6] A 1985 study found that triazolam and temazepam maintained higher rates of self-injection than a variety of other benzodiazepines.[7] A 1991 study indicated that diazepam, in ...
