Cohen, S., N. Parvizi, E. J. H. Mulder, H. A. Van Oord, F. H. Jonker, G. C. Van Der Weijden, and M. A. M. Taverne. Effects of morphine and naloxone on fetal heart rate and movement in the pig. J Appl Physiol 90: 15771583, 2001.--To test the hypothesis that an increasing opioid tonus is involved in decreases in fetal heart rate FHR ; and movement FM ; during late gestation, we studied the effects of intravenous bolus injections of morphine 1 mg ; and naloxone 1 mg ; on FHR and FM in the fetal pig. Twenty-one fetuses 1 per sow ; were catheterized at 90104 days of gestation median 100 days ; . Recordings of FHR electrocardiograph or Doppler-derived signals ; and FM ultrasonography ; were made from 15 min before to 45 min after treatment. Morphine administration significantly decreased FHR, but it increased FHR variation and forelimb movements LM ; . LM were clustered, and this stereotyped behavior has never before been observed in any mammalian fetus. Naloxone administration increased gross body movements and FHR without significant changes in FHR variation. It is concluded that FHR and motility are under opioidergic control in the pig fetus. Both morphine and naloxone induce hypermotility, suggesting that naloxone does not act as a pure opioid antagonist in the fetal pig. fetus; opioids; motility; ultrasound.
Major antituberculous drugs usually isoniazid INH ; and rifampin RMP and cause intractable TB, has greatly contributed to the increased incidence of TB3. For instance, well-documented outbreaks or mini-epidemics of MDR-TB in the U. S. have indicated extremely rapid progression of this disease with an associated high rate of mortality, particularly in HIV-infected patients. At present, the most effective therapy for TB is the use of the most active antituberculous drugs, such.
Naloxone should be administered cautiously to persons known or suspected to be physically dependent on levorphanol.

Significantly decreased for group- and single-housed animals and, for group-housed animals, selfgrooming decreased with outdoor housing. In phase 2, rates of self-biting, time engaging in idiosyncratic self-directed stereotypies, and yawning remained significantly lower during weeks 7 through 12 outdoor housing ; compared with those under indoor housing. Rates of scratching and time spent self-grooming decreased significantly during the first 6 wk but then returned to baseline levels. Our findings suggest that self-biting and self-directed stereotypic behavior in rhesus macaques with a history of self-injurious behavior is significantly reduced by outdoor housing regardless of whether animals are socially or individually housed. Di Martino, E. F., R. Thaden, et al. 2006 ; . "Evaluation of Eustachian tube function by sonotubometry: results and reliability of 8 kHz signals in normal subjects." Eur Arch Otorhinolaryngol. Sonotubometry allows an assessment of the Eustachian tube ET ; function under physiological conditions. The reliability of the application of an 8 kHz pure-tone signal was investigated. In 40 normal subjects 80 ears ; sonotubometric studies were performed with a custom-made device. ET opening was provoked by swallowing, yawning and Valsalva manoeuvre. An opening was detected in all patients but not in all manoeuvres. Four characteristic sonotubogram types were found. Most common was the spike-type 60% ; . The double-peak and the plateau-shaped curves occured in 17% each. The finding of an descendant curve was rare 5% ; . Of 623 measurements, only in 55% manouvres a positive sonotubometric result was found despite the fact that the patients reported an opening in all cases. The median opening time in dry swallowing, liquid swallowing, yawning and Valsalva was found to be 486, 355, 1, and 1, 250 ms. A median sound increase of 16.0, 13.8, 15.0 and 15.0 dB was recorded for these manoeuvres. There was a statistic significant difference P 0.02 ; between the increase in sound intensity of liquid and dry swallowing. There was also a statistic significant difference found for the duration of the forced manoeuvres Valsalva and yawning as compared to dry and liquid swallowing P 0.0001 ; . The use of an 8 kHz pure-tone signal showed a limited sensitivity for the detection of ET openings. This is mainly due to noise pollution, but also because of an altered positioning and or dislocation of the probes and compression of the nostrils. The application of an 8 kHz signal is therefore not reliable enough for the use in practice. Further technical refinements and the use of alternative signals are necessary for a broader clinical application. Cheng, T. O. 2006 ; . "More about yawning." J Cardiol 97 10 ; : 1547-9. Cattaneo, L., L. Cucurachi, et al. 2006 ; . "Pathological yawning as a presenting symptom of brain stem ischaemia in two patients." J Neurol Neurosurg Psychiatry 77 1 ; : 98-100. Two cases of brain stem stroke involving the upper pons and the ponto-mesencephalic junction presented with transient excessive pathological yawning, associated with gait ataxia and in one subject with upper limb and facial hemiparesis. A causal relation is hypothesised between the brain stem lesion and pathological yawning, possibly related to denervation hypersensitivity of a putative brain stem yawn centre. Excessive yawning may herald brain stem ischaemia. Brown, R. W., M. K. Perna, et al. 2006 ; . "The effects of adulthood nicotine treatment on D2-mediated behavior and neurotrophins of rats neonatally treated with quinpirole." Synapse 59 5 ; : 253-9. This study was designed to analyze the effects of nicotine on yawning behavior and neurotrophin content in the hippocampus and frontal cortex of D2-receptor primed female adult Sprague-Dawley rats. Animals were neonatally treated with quinpirole, a dopamine DA ; D2 D3 agonist, from postnatal day 1-21 P1-21 ; and raised to P60 and administered nicotine tartarate 0.3 mg kg free base ; or saline twice daily for 14 days. One day after nicotine treatment had ceased, the number of yawns was recorded for 1 h in response to an acute injection of quinpirole i.p., 100 microg kg ; . Yawning is a D2-receptor mediated event. D2-primed rats demonstrated a significant increase in yawning in response to acute quinpirole compared with that of controls, but nicotine did not alleviate this effect. Neonatal quinpirole treatment produced a significant decrease of nerve growth factor NGF ; and brain-derived neurotrophic factor BDNF ; in the hippocampus that was alleviated by adulthood nicotine treatment. Interestingly, nicotine treatment to controls produced a significant increase of NGF in the frontal cortex, but a significant decrease of both NGF and BDNF in the hippocampus and BDNF in the frontal cortex. The decreases shown in NGF and BDNF is contrary to past findings that have shown nicotine to produce significant increases of hippocampal NGF and BDNF, but these past studies utilized male rats or mice or were performed in vitro. This study shows that nicotine has complex interactions with NGF and BDNF in D2-primed and control animals, and emphasizes the importance of gender differences when analyzing nicotine's effects on neurotrophins. Wu, C. C., J. Y. Chen, et al. 2005 ; . "Serotonin reuptake inhibitors attenuate morphine withdrawal syndrome in neonatal rats passively exposed to morphine." Eur J Pharmacol 512 1 ; : 37-42. Previous investigations had shown that inhibitor of serotonin reuptake transporter SERT ; could attenuate morphine withdrawal syndrome in adult animals. In the present study, we determined whether postnatal injection of serotonin reuptake inhibitors, fluoxetine, clomipramine, or citalopram, is able to attenuate the expression of the naloxone-precipitated morphine withdrawal syndrome in 5-day-old neonatal SpraugeDawley rats born to dams rat that received morphine injection since a week before mating till 5 days after delivery. Withdrawal syndrome of morphine, manifested as frequent abdominal stretching and yawning, was generated by injection of naloxone on postnatal day 5. Pre-injection with fluoxetine, clomipramine, or citalopram, significantly attenuated the naloxone-precipitated syndrome in a dose-dependent manner.

Single-wall carbon nanohorn assembly as a potential applicant for hydrogen and methane storage Katsuyuki Murata, Hideki Tanaka, Masako Yudasaka, Sumio Iijima, Daisuke Kasuya, Hirofumi Kanoh, Katsumi Kaneko Department of Chemistry, Faculty of Science, Chiba University, Japan, Phone + 81-43-290-2770, Fax + 81-43290-2788, e-mail murata pchem2.s.chiba-u.ac.jp Single-wall carbon nanotubes SWNTs ; are expected for having potential for clean energy gas storage, especially methane and hydrogen. The mechanism of hydrogen and methane storage on SWNT is not well understood, although many researchers have studied the storage of these gases using SWNTs. We examined both experimentally and theoretically the adsorption mechanism of methane and hydrogen on single-wall carbon nanohorn SWNH ; assemblies, a highly pure and SWNT-related material. The heat of adsorption of hydrogen on internal SWNH nanospaces was estimated to be 5-6 kJ mol that is about 4 kJ mol larger than the enthalpy change of vaporization of hydrogen; nanospaces of SWNHs stabilize hydrogen molecules. On the other hand, the density of methane in nanospaces of SWNHs achieved liquid-like density even at 303 K above critical temperature, which is caused by enhanced methane-methane interaction in nanospaces of SWNHs. We will discuss adsorption mechanism for these gases and the possibility of the storage potential of SWNHs and nardil.

Not yield a false-positive result. Also, because the follow-up period for our study was relatively short 3 years ; , we cannot exclude the possibility that homocysteine levels are elevated because of the presence of subclinical atherosclerosis. This possibility has been raised in at least 1 prior prospective study of men in which homocysteine level was found to be a better predictor of short-term risk than long-term risk.8, 9 On the other hand, because the blood samples in our study were obtained prior to the onset of first cardiovascular events, we can exclude the possibility that the elevations observed in our data are a result rather than a cause of acute vascular occlusion. In addition, we did not ascertain allele status for the methylenetetrahydrofolate reductase gene in this population. However, a series of studies has reported that methylenetetrahydrofoREFERENCES 1.

Carcinoma ; was later found. Neither of the two patients could precipitate their pain with imitation of yawning and neither had evidence of Eagle syndrome. Only the second patient had a history of migraine. Yawning pain may have an extratrigeminal and extracephalic distribution. It rarely serves to identify a lesion underlying the area where the pain is perceived. Farmer, P. and N. G. Campos 2004 ; . "Rethinking medical ethics: a view from below." Developing World Bioeth 4 1 ; : 17-41. In this paper, we argue that lack of access to the fruits of modern medicine and the science that informs it is an important and neglected topic within bioethics and medical ethics. This is especially clear to those working in what are now termed 'resource-poor settings'- to those working, in plain language, among populations living in dire poverty. We draw on our experience with infectious diseases in some of the poorest communities in the world to interrogate the central imperatives of bioethics and medical ethics. AIDS, tuberculosis, and malaria are the three leading infectious killers of adults in the world today. Because each disease is treatable with already available therapies, the lack of access to medical care is widely perceived in heavily disease-burdened areas as constituting an ethical and moral dilemma. In settings in which research on these diseases are conducted but there is little in the way of therapy, there is much talk of first world diagnostics and third world therapeutics. Here we call for the 'resocialising' of ethics. To resocialise medical ethics will involve using the socialising disciplines to contextualise fully ethical dilemmas in settings of poverty and, a related gambit, the systematic participation of the destitute sick. Clinical research across steep gradients also needs to be linked with the interventions that are demanded by the poor and otherwise marginalised. We conclude that medical ethics must grapple more persistently with the growing problem posed by the yawning 'outcome gap' between rich and poor. Eguibar, J. R., M. Barajas, et al. 2004 ; . "Genotype-dependent effect of ACTH 1-24 ; on grooming and yawning in two inbred strains of rats." Neuropeptides 38 5 ; : 283-8. It has long been known that the intracerebroventricular administration of ACTH 1-24 ; increases the duration of grooming episodes and the frequency of yawning in rats. The objective of this study was to investigate in what way these episodes are prolonged and whether and to what extent genotype influences such effects. We compared the effect of increasing doses of intracerebroventricular injections of ACTH 124 ; on grooming and yawning in males of two inbred strains of Sprague-Dawley rats with distinct yawning frequency, high-yawning HY ; and low-yawning LY ; . In LY rats the duration of grooming episodes increased, while in HY rats grooming episodes augmented both in number and duration. In LY rats the duration of grooming components increased likewise, in HY rats however, neither the number nor the duration of the components changed. The grooming rate in both strains of rats was slowed, though more so in LY than in HY rats. Yawning increased in LY rats but not in HY rats. We conclude therefore that ACTH 124 ; increases the duration of grooming episodes by slowing the grooming rate according to genotype, and may or may not alter the frequency of yawning. Duncan, I., P.

"The brain stem but not forebrain independently supports morphine tolerance and withdrawal effects in cats." Behav Brain Res 148 1-2 ; : 133-44. We employed polygraphic recordings and behavioral measures to study the effects of chronic morphine use upon the isolated forebrain and the decerebrate animal in cats with a midbrain transection. Cats received morphine for 12 days, and 24 h recording sessions were conducted on days 1 and 11. For the decerebrate cat, the percent time of rapid eye movement REM ; sleep was reduced during the 24 h period on both days 1 and 11. However, the values on day 11 were consistently higher than the values on day 1. Other tolerance indicators were decreases in the number of early behavioral signs and in the onset delay for REM sleep, together with an increase in onset time for motor activation. After naloxone day 12 ; all cats displayed "wet shakes, " tachypnea and eye squinting, as well as either pyloerection, elevated tail, salivation, licking, micturition, and yawning. In the isolated forebrain, the percent time for waking increased through the first 18 h post-morphine on both days 1 and 11. Conversely, the duration of nonREM NREM ; sleep and of drowsiness decreased. But importantly, the duration of sleep-waking states did not vary between days 11 and 1, indicating absence of tolerance. Additionally, after naloxone, the isolated forebrain entered NREM sleep, contrasting with opposite findings in intact cats. Therefore, while we could not demonstrate chronic use effects in the isolated forebrain, the decerebrate cat still displayed typical tolerance withdrawal manifestations. This suggests that the effects of chronic opiate use are deeply seated in the brain stem, which might help understanding the ingrained nature of physical dependence. Brown, R. W., K. D. Thompson, et al. 2004 ; . "Adulthood nicotine treatment alleviates behavioural impairments in rats neonatally treated with quinpirole: possible roles of acetylcholine function and neurotrophic factor expression." Eur J Neurosci 19 6 ; : 1634-42. Increases in dopamine D 2 ; receptor sensitivity are known to be common in drug abuse and neurological disorders. Past data from this laboratory have shown that long-term increases in D 2 ; sensitivity can be produced by quinpirole treatment a D 2 ; agonist ; during early development. The present investigation was designed to test the hypothesis that nicotine administration in adulthood would reduce both cognitive and skilled reaching impairments produced by increases in D 2 ; sensitivity. Female Sprague-Dawley rats were treated with quinpirole 1 mg kg ; or saline from postnatal day 1 PD 1 ; 21. Beginning in adulthood PD 61 ; , rats were treated with nicotine 0.3 mg kg free base ; or saline twice daily and natalizumab.

A special kind of smokeless tobacco also known as Maras Powder MP ; is widely used in South eastern region especially Kahramanmaras, Gaziantep and other south eastern cities of Turkey. It is obtained from a tobacco species, Nicotina rustica L. NRL ; and ash of oak or grapevine wood. The aim was to investigate the effect of nicotine on haematological parameters in MP users. Method: Sixty-nine MP users from Kahramanmaras and its environs and 30 healthy controls who did not use MP were and naloxone.
Overview: naloxone when available ; pharmacology and use : naloxone is an opiate antagonist and prevents or reverses the effects of opioids including respiratory depression, sedation and hypotension and natrecor.
