The role of ATP and astrocytes in respiratory rhythm modulation has been recently investigated in neonatal rodents. However, no information on the role of ATP and astrocytes within the respiratory network of the lamprey is available, particularly within the paratrigeminal respiratory group (pTRG), the proposed respiratory central pattern generator. To address these issues, the present study was carried out on isolated brainstems of the adult lamprey. Bath application of ATP caused marked increases in respiratory frequency followed by decreases in the respiratory motor output, mediated by the ATP metabolite adenosine at the level of the pTRG...

: Ketamine's history begins in the 1950s in Detroit, Michigan, at Parke-Davis Laboratories. On 26 March 1956, Harold V. Maddox synthesised phencyclidine or PCP. Domino studied PCP effects in animals and in 1958, Greifenstein made the first trials of PCP in humans under the name of Sernyl. Sernyl did not cause depression of cardiovascular and respiratory functions, but elicited severe excitation with a very prolonged postoperative recovery. Because of its psychedelic effects, it became a street drug under the name of 'angel dust' and was placed on schedule II of Federal Controlled Substance Act (CSA) in 1978...

PURPOSE: Although capnography is considered the gold standard for monitoring of ventilation, it may not work accurately in some situations. We compared the performance of two non-invasive continuous respiratory rate (RR) monitors that are alternatives for the detection of respiratory depression. METHODS: Fifty healthy volunteers ≥20 years old were enrolled in this study. After monitoring of the volunteers was started by the Masimo Radical-7(®) and Nellcor™ PM1000N, they breathed at the rate of 12 breaths/min for 3 min and then stopped breathing...

Riluzole blocks persistent Na(+) current, inhibits generation of neuronal bursts and decreases glutamate-induced excitotoxicity. In previous studies of respiratory activity, riluzole suppressed inspiratory-related burst generation activity in rat slice or en bloc preparations. We examined riluzole's effects on inspiratory burst generation and drug-induced seizure-like activity in newborn rat en bloc preparations. Medulla-spinal cord preparations from postnatal day 0-3 Wistar rats were isolated under deep isoflurane anesthesia and were superfused with artificial cerebrospinal fluid equilibrated with 95% O2 and 5% CO2, pH 7...

INTRODUCTION: The long allele of the DRD4 gene can confer different behavioral and emotional phenotypes depending upon environmental exposure, although the physiological changes underlying these phenotypes are not fully known. We sought to extend this work by assessing the interaction of the DRD4 gene and exposure to perinatal adversity (indexed by extremely low birth weight [ELBW]) on resting respiratory sinus arrhythmia (RSA), a neurophysiological measure of emotion regulation, in adulthood...

The goal of this study was to determine the minimum alveolar concentration (MAC) and cardiopulmonary effects of isoflurane in ring-tailed lemurs (Lemur catta). The MAC of isoflurane was determined by using a tail-clamp stimulus in adult ring-tailed lemurs (6 male, 4 female). Once MAC was determined, another group of 10 adult ring-tailed lemurs (5 male, 5 female) were anesthetized and instrumented similarly as the previous group and maintained at 0.5, 1, 1.5, and 2 times MAC for 15 min each with no external stimulation...

Hydrogen sulfide (H2 S) is a highly neurotoxic gas. It is the second most common cause of gas-induced deaths. Beyond mortality, surviving victims of acute exposure may suffer long-term neurological sequelae. There is a need to develop countermeasures against H2 S poisoning. However, no translational animal model of H2 S-induced neurological sequelae exists. Here, we describe a novel mouse model of H2 S-induced neurotoxicity for translational research. In paradigm I, C57/BL6 mice were exposed to 765 ppm H2 S for 40 min on day 1, followed by 15-min daily exposures for periods ranging from 1 to 6 days...

Hydrogen Sulfide (H2S) is one of three gasotransmitters that modulate excitability in the CNS. Global application of H2S donors or inhibitors of H2S synthesis to the respiratory network has suggested that inspiratory rhythm is modulated by exogenous and endogenous H2S. However, effects have been variable, which may reflect that the RTN/pFRG (retrotrapezoid nucleus, parafacial respiratory group) and the preBötzinger Complex (preBötC, critical for inspiratory rhythm generation) are differentially modulated by exogenous H2S...

Neural mechanisms of obstructive sleep apnea, a common sleep-related breathing disorder, are incompletely understood. Hypoglossal motoneurons, which provide tonic and inspiratory activation of genioglossus (GG) muscle (a major upper airway dilator), receive catecholaminergic input from medullary A1/C1 neurons. We aimed to determine the contribution of A1/C1 neurons in control of GG muscle during sleep and wakefulness. To do so, we placed injections of a viral vector into DBH-cre mice to selectively express the hMD4i inhibitory chemoreceptors in A1/C1 neurons...

Opioid analgesics are the standards of care for the treatment of moderate to severe nociceptive pain, particularly in the setting of cancer and surgery. Their analgesic properties mainly emanate from stimulation of the μ receptors, which are encoded by the OPRM1 gene. Hepatic metabolism represents the major route of elimination, which, for some opioids, namely codeine and tramadol, is necessary for their bioactivation into more potent analgesics. The highly polymorphic nature of the genes coding for phase I and phase II enzymes (pharmacokinetics genes) that are involved in the metabolism and bioactivation of opioids suggests a potential interindividual variation in their disposition and, most likely, response...

Mammalian hibernation is characterized by metabolic rate depression and a strong decrease in core body temperature. Brown adipose tissue (BAT), a thermogenic tissue that uses uncoupled mitochondrial respiration to generate heat instead of ATP, plays a major role in rewarming from deep torpor. In the present study we developed a label-free LC-MS strategy to investigate both differential protein expression and protein phosphorylation in BAT extracts from euthermic versus hibernating ground squirrels. In particular, we incorporated the filter-assisted sample preparation (FASP) protocol, which provides a more in-depth analysis compared with gel-based and other LC-MS proteomics approaches...
