    Patients in an outpatient narcotic antagonist treatment program were followed through their course of treatment. Those who remained longer were found to enter treatment with more stable employment records and less recent opiate use. They also appeared more successful at termination, with better vocational stability, less extraneous drug use, and…

    1 The treatment of pain of cardiac origin requires a knowledge of the haemodynamic action of the analgesic agents used. 2 The haemodynamic effects of morphine, diamorphine, pavaveretum, pethidine and pentazocine are reviewed. 3 Clinical experience with the new antagonist analgesic buprenorphine is reported. 4 These studies indicate that buprenorphine may be the agent of choice for the relief of severe pain in patients with unstable circulation.

  4. Use of narcotic antagonists to modify stereotypic self-licking, self-chewing, and scratching behavior in dogs.

    PubMed

    Dodman, N H; Shuster, L; White, S D; Court, M H; Parker, D; Dixon, R

    1988-10-01

    We evaluated 2 narcotic antagonists, naltrexone and nalmefene, for treatment of refractory self-licking, self-chewing, and scratching behavior in dogs. Eleven dogs with various irritative or pruritic disorders were medicated with naltrexone (1 mg/kg of body weight, sc) or nalmefene (1 to 4 mg/kg, sc), after a period of control observation during which the dogs had not been medicated. The time for which the dogs were involved in self-licking, self-chewing, or scratching was determined retrospectively by analysis of videotapes. The rates of involvement in either activity before and after treatment were calculated and compared statistically. Treatment with a narcotic antagonist significantly reduced the time spent self-licking, self-chewing, or scratching in 7 of 11 dogs, was partially effective in 3 dogs, and was ineffective in one dog. Dogs with acral lick dermatitis responded most to treatment.

  5. In vivo and in vitro evaluation of a microencapsulated narcotic antagonist.

    PubMed

    Mason, N; Thies, C; Cicero, T J

    1976-06-01

    Injectable microcapsules containing 75% (w/w) cyclazocine, a narcotic antagonist, were prepared with dl-poly(lactic acid) as the coating material. Capsule fractions falling between 105 and 295 mum released about 90% of their cyclazocine in 8 days of rotating-bottle extraction at 37 degrees in pH 7.4 phosphate buffer. Although larger capsules released the drug somewhat more slowly, all capsules released cyclazocine far more rapidly than an ideal capsule should. This rapid release is attributed to macroscopic defects located in the capsule walls. The ability of the capsules to block the action of morphine in vivo was assessed by injection of a sesame seed oil suspension into Holtzman rats. A hot-plate test procedure was used to evaluate animal behavior. Capsule doses of 100-250 mg/kg to rats caused significant antagonism of morphine's analgesic effect for 14 days after injection. By Day 17, no antagonism occurred, indicating that the capsules completely released the drug in vivo between 14 and 17 days after injection.

  6. Effect of intravenously-administered putative and potential antagonists of ethanol on sleep time in ethanol-narcotized mice

    Hatch, R.C.; Jernigan, A.D.

    1988-01-01

    Groups of male CD-1 mice (n = 12/group) were injected intraperitoneally (IP) with 5 g ethanol/kg of body weight. After loss of righting reflex, they were given vehicle or one of 2-3 doses of reputed or potential antagonists of ethanol intravenously (IV). Sleep time was measured from loss to return of righting reflex. Mean sleep time (MST) was increased significantly by a large dose of dl-amphetamine and by 4-aminopyridine. Significant increases were also produced by small and large doses of aminophylline and by yohimbine. MST was not altered significantly by small and medium doses of dl-amphetamine, a medium dose of aminophylline, or by any doses of naloxone, thyrotropin-releasing hormone, propranolol, physostigmine, doxapram, or Ro 15-4513. When Ro 15-4513 was given IP 15 minutes before ethanol (n = 6/group), onset and duration of narcosis were not altered. None of the compounds tested was an effective IV antidote for deep ethanol narcosis because of drug side effects, toxicity, prolongation of MST, or insufficient shortening of MST. 36 references, 1 table.

    The Narcotics Detection Technology Assessment (NDTA) program is a series of studies conducted to evaluate illicit substance detection devices. The ability to effectively detect cocaine and heroin particles is directly related to the efficiency of a detection device's sample collection design. The NDTA tests are therefore structured to require sampling of narcotics from a surface. Tests standards are required which permit subnanogram to microgram quantities of narcotic to be dispensed onto a target surface for sampling. Optimally, the standard should not adversely affect the performance of the device under test. The NDTA test team has developed and experimentally characterized solution- deposited substrate standards, solution-deposited substrate- free standards, vapor-deposited standards, suspension standards, and dry mix standards, and dry mix standards. A variety of substrates and dry-mix fillers have been evaluated, including sand, fullerenes, copper powder, nickel powder, pulverized paper, and aluminum. Suspension standards were explored with a variety of liquids. The narcotic standards with the best performance were found to be dry mixes of cocaine with silver-coated nickel powder, and dry mixes of heroin with silanized glass beads.

    Patients with rheumatic conditions often suffer from related chronic pain. When first-line traditional medications such as acetaminophen and anti-inflammatory medications do not suffice, then other options are needed. The traditional medications may ultimately not provide sufficient pain relief, or alternatively, they can pose as a contraindication due to underlying hypertension, renal, and/or hepatic disease. Therefore, narcotics are an alluring alternative, which if used in a multidisciplinary and systematic approach to the patient, can prove to be quite beneficial in the lives of these patients.

  14. New narcotics in anesthesia.

    PubMed

    Borel, J D

    1983-01-01

    Recent research has led to the development of a new family of synthetic narcotic fentanyl derivatives. Two of these, sufentanil and alfentanil, are already in clinical use abroad and are presently under clinical investigation in the United States. Sufentanil is more potent than fentanyl and is claimed to have fewer side effects and less variability in patient cardiovascular responses under stress. It appears that its primary application will be for high-dose narcotic anesthesia in patients with cardiovascular disease. Alfentanil has a shorter duration of action and is claimed to have less postoperative ventilatory depression than fentanyl. It is being recommended for use via continuous intravenous infusion. It will probably become a popular anesthetic agent for outpatient and short surgical procedures. It should be remembered that at this time very little information concerning these agents is in print. Most of the research has been done by a handful of investigators and much has not been published in peer review publications. Based on the clinical impressions of our European colleagues, one can say that these agents should be as safe and as reliable as fentanyl, but any clinically significant advantages over their parent compound, especially in the case of sufentanil, will have to await more widespread use and controlled investigation.

    2015-12-01

    Patients with cancer are increasingly opting for home health care, resulting in a rapid increase in the number of prescriptions for narcotics aimed at pain control. As these narcotics are issued by pharmacies only upon presentation of valid prescriptions, the quantity stored in the pharmacies is of importance. Although many pharmaceutical outlets are certified for retail sale of narcotic drugs, the available stock is often extremely limited in variety and quantity. Affiliated stores of wholesale(or central wholesale)dealers do not always have the necessary certifications to provide medical narcotics. Invariably, the quantity stored by individual branches or sales offices is also limited. Hence, it may prove difficult to urgently secure the necessary and appropriate drugs according to prescription in certain areas of the community. This report discusses the problems faced by wholesalers and pharmacies during acquisition, storage, supply, and issue of prescription opioids from a stockpiling perspective.

  6. Probes for narcotic receptor mediated phenomena. 44. Synthesis of an N-substituted 4-hydroxy-5-(3-hydroxyphenyl)morphan with high affinity and selective μ-antagonist activity

    A simple three-step synthesis of 5-(3-hydroxyphenyl)-2-methyl-2-azabicyclo[3.3.1]nonan-4-ol (3a) was achieved using an osmium tetroxide mediated oxidation of the known intermediate 6. A pyrrolidine-ring variant of 3a (3-(7-(hydroxymethyl)-6-methyl-6-azabicyclo[3.2.1]octan-1-yl)phenol (5)) was isolated when other routes were used. The epimeric hydroxy analogue 4a was synthesized by simple inversion of the stereochemistry at C-4. Both N-methyl (3a and 4a) and N-phenethyl (3b and 4b) derivatives were synthesized. The compounds were examined for their opioid receptor affinity and the N-phenethyl analogue 3b was found to have relatively weak affinity for the μ-opioid receptor (Ki = 74 nM). However, the N-phenethyl analogue of the C-4 epimer, 4b, had about 15 fold higher affinity than 3b and was selective for the μ-opioid receptor (Ki = 4.6 nM). Compound 4b was a moderately potent μ-opioid antagonist (Ke = 12 nM), as determined by [35S]GTP-γ-S assays. Compounds 3b and 4b were energy minimized at the level of B3LYP/6-31G*, and then overlaid onto the 5-phenylmorphan, the (1R,5R,9S)-(−)-enantiomer of 2b (Fig. 1) with the α or β-OH group at the C-9 position. The spatial orientation of the hydroxyl moiety in 3b, 4b, 2a, and 2b is proposed to be the structural requirement for high μ-opioid receptor binding affinity and their agonist or antagonist activity. The modest change in spatial position of the hydroxyl moiety, and not the N-substituent, induced the change from potent agonist to an antagonist of moderate potency. PMID:22341895

  2. Narcotics detection using piezoelectric ringing

    NASA Astrophysics Data System (ADS)

    Rayner, Timothy J.; Magnuson, Erik E.; West, Rebecca; Lyndquist, R.

    1997-02-01

    Piezo-electric ringing (PER) has been demonstrated to be an effective means of scanning cargo for the presence of hidden narcotics. The PER signal is characteristic of certain types of crystallized material, such as cocaine hydrochloride. However, the PER signal cannot be used to conclusively identify all types of narcotic material, as the signal is not unique. For the purposes of cargo scanning, the PER technique is therefore most effective when used in combination with quadrupole resonance analysis (QRA). PER shares the same methodology as QRA technology, and can therefore be very easily and inexpensively integrated into existing QRA detectors. PER can be used as a pre-scanning technique before the QRA scan is applied and, because the PER scan is of a very short duration, can effectively offset some of the throughput limitations of standard QRA narcotics detectors. Following is a discussion of a PER detector developed by Quantum Manetics under contract to United States Customs. Design philosophy and performance are discussed, supported by results from recent tests conducted by the U.S. Drug Enforcement Agency and U.S. Customs.

  3. Quadrupole resonance scanner for narcotics detection

    NASA Astrophysics Data System (ADS)

    Shaw, Julian D.; Moeller, C. R.; Magnuson, Erik E.; Sheldon, Alan G.

    1994-10-01

    Interest in non-invasive, non-hazardous, bulk detection technologies for narcotics interdiction has risen over the last few years. As part of our continuing research and development programs in detection of narcotics and explosives using sensitive magnetic measuring devices, we present the first commercially available prototype Quadrupole Resonance (QR) scanner for narcotics detection. The portable narcotics detection system was designed in modular form such that a single QR base system could be easily used with a variety of custom detection heads. The QR system presented in this paper is suitable for scanning items up to 61 X 35 X 13 cm in size, and was designed to scan mail packages and briefcase-sized items for the presence of narcotics. System tests have shown that detection sensitivity is comparable that obtained in laboratory systems.

    2009-01-01

    Toxicity data on chemicals, supposed to have a narcotic or polar narcotic toxicological mode of action, have been produced on the luminescent bacterium Vibrio fischeri using the Microtox test procedure. Advanced statistical methods have been used to calculate statistically sound values for ecotoxicological endpoints. Simple quantitative structure activity relationship (QSAR) equations were developed for narcotics and polar narcotics. These equations were compared with those proposed by the European Technical Guidance Document on Risk Assessment for other aquatic organisms (algae, Daphnia, and fish). Similarities and differences are discussed. The need for including the bacterial component in the ecotoxicological risk assessment for aquatic ecosystems is highlighted.

    1993-12-31

    Efficient personnel performance, a major requirement for a safe nuclear industry, is jeopardized where personnel use narcotics. However, detection of narcotics at nuclear plants is a challenge. The unique specificity and sensitivity of an immunoassay has been implemented in the form of a small, dry immunoassay film badge (IFB) for the detection of vapors emitted by narcotics. The device is suitable as an area monitor, and its characteristics are suitable for use as a breath monitor for the detection of drug use.

  13. Lethal body burdens of polar narcotics: Chlorophenols

    SciTech Connect

    Wezel, A.P. van; Punte, S.S.; Opperhuizen, A.

    1995-09-01

    The goal of the present study was to measure in fathead minnow (Pimephales promelas) the lethal body burden (LBB) of three chlorophenols that are known as polar narcotic chemicals. The LBBs of the chlorophenols were compared to LBBs of nonpolar narcotic chemicals to consider if the two classes of narcotic chemicals differ on a body burden level. The LBB of the most acidic chlorophenol was measured at two different levels of pH exposure to determine the influence of the degree of ionization on the magnitude of the LBB. Both n-octanol/water partition coefficients and n-hexane/water partition coefficients of the chlorophenols were determined at different pH levels to consider the influence of ionization on the partition coefficient and to determine the importance of a polar group in the organic phase on the partitioning behavior. Partitioning to n-octanol and n-hexane was used as input in a model to simulate the equilibrium partitioning between hydrophobic and nonhydrophobic and target and nontarget compartments in the fish.

  3. Kisspeptin antagonists.

    PubMed

    Roseweir, Antonia Kathryn; Millar, Robert P

    2013-01-01

    Kisspeptin is now known to be an important regulator of the hypothalamic--pituitary-gonadal axis and is the target of a range of regulators, such as steroid hormone feedback, nutritional and metabolic regulation. Kisspeptin binds to its cognate receptor, KISS1R (also called GPR54), on GnRH neurons and stimulates their activity, which in turn provides an obligatory signal for GnRH secretion-thus gating down-stream events supporting reproduction. The development of peripherally active kisspeptin antagonists could offer a unique therapeutic agent for treating hormone-dependent disorders of reproduction, including precocious puberty, endometriosis, and metastatic prostate cancer. The following chapter discusses the advances made in the search for both peptide and small molecule kisspeptin antagonists and their use in delineating the role of kisspeptin within the reproductive system. To date, four peptide antagonists and one small molecule antagonist have been designed.

    2014-03-01

    Despite their frequent use, allergy to illicit drugs and narcotics is rarely reported in literature. We present a review of the different classes of drugs of abuse that might be involved in allergies: central nervous system (CNS) depressants (such as cannabis, opioids and kava), CNS stimulants (cocaine, amphetamines, khat and ephedra) and hallucinogens such as ketamine and nutmeg. Diagnosis of drug and narcotic allergy generally relies upon careful history taking, complemented with skin testing eventually along with quantification of sIgE. However, for various reasons, correct diagnosis of most of these drug allergies is not straightforward. For example, the native plant material applied for skin testing and sIgE antibody tests might harbour irrelevant IgE-binding structures that hamper correct diagnosis. Diagnosis might also be hampered due to uncertainties associated with the non-specific histamine releasing characteristics of some compounds and absence of validated sIgE tests. Whether the introduction of standardized allergen components and more functional tests, that is, basophil activation and degranulation assays, might be helpful to an improved diagnosis needs to be established. It is anticipated that due to the rare character of these allergies further validation is although necessary.

    2014-01-01

    Background The reinforcing properties of nicotine may be mediated through release of various neurotransmitters both centrally and systemically. People who smoke report positive effects such as pleasure, arousal, and relaxation as well as relief of negative affect, tension, and anxiety. Opioid (narcotic) antagonists are of particular interest to investigators as potential agents to attenuate the rewarding effects of cigarette smoking. Objectives To evaluate the efficacy of opioid antagonists in promoting long-term smoking cessation. The drugs include naloxone and the longer-acting opioid antagonist naltrexone. Search methods We searched the Cochrane Tobacco Addiction Group Specialised Register for trials of naloxone, naltrexone and other opioid antagonists and conducted an additional search of MEDLINE using ’Narcotic antagonists’ and smoking terms in April 2013. We also contacted investigators, when possible, for information on unpublished studies. Selection criteria We considered randomised controlled trials comparing opioid antagonists to placebo or an alternative therapeutic control for smoking cessation. We included in the meta-analysis only those trials which reported data on abstinence for a minimum of six months. We also reviewed, for descriptive purposes, results from short-term laboratory-based studies of opioid antagonists designed to evaluate psycho-biological mediating variables associated with nicotine dependence. Data collection and analysis We extracted data in duplicate on the study population, the nature of the drug therapy, the outcome measures, method of randomisation, and completeness of follow-up. The main outcome measure was abstinence from smoking after at least six months follow-up in patients smoking at baseline. Abstinence at end of treatment was a secondary outcome. We extracted cotinine- or carbon monoxide-verified abstinence where available. Where appropriate, we performed meta-analysis, pooling risk ratios using a Mantel

  6. Multimodal analgesia without routine parenteral narcotics for total hip arthroplasty.

    2006-12-01

    Methods for managing pain after a total hip replacement have changed substantially in the past 5 years. We documented the outcome of patients treated with a multimodal pain program designed to avoid parenteral narcotics. Avoidance of parenteral narcotics can essentially eliminate the complications of respiratory depression, ileus, and narcotic-induced hypotension. It can minimize nausea and vomiting which cause dissatisfaction with an operation. Twenty-one of 140 patients (15%) needed parenteral narcotics postoperatively with only nine patients (6.4%) using parenteral narcotics after the day of surgery. Mean pain scores were below 3 of 10 on all postoperative days. There were no patients with respiratory depression or ileus, and four (2.9%) with urinary retention. Nausea occurred with 35 patients (25%) in the recovery room and in 28 patients (20%) thereafter. Emesis occurred in five patients (3.6%) with two incidences in the recovery room. One hundred and thirty-eight patients (98.6%) were discharged home at a mean of 2.7 seven days postoperatively with 98 (70%) on a single assistive device. The multimodal pain management program, which avoided parenteral narcotics, was effective in providing pain relief, nearly eliminating emesis, and eliminating the severe complications of respiratory depression, urinary tract infection and ileus, as well as accelerating function.

  7. Portable narcotics detector with identification capability

    A portable hand held hidden substance detector has been developed and manufactured. Neutrons from a californium-252 source are emitted through the front face of the Compact Integrated Narcotics Detection Instrument (CINDI) and penetrate dense compartment materials with little change in energy, but are backscattered by hydrogen rich materials such as drugs. These backscattered neutrons can be readily detected. CINDI incorporates a highly sensitive detection scheme which permits the use of weak radioactive sources for safety without compromising detectability. CINDI is able to detect hydrogen-dense materials most effectively directly behind panels made of steel, wood, fiberglass, or even lead-lined materials. This makes it useful for inspecting marine vessels, ship bulkheads, automobiles, structure walls, or small sealed containers. The present CINDI version selectively detects hydrogen rich substances only. The new technique will detect both neutrons and gamma rays simultaneously. The backscatter mechanism of gamma rays and neutrons are sufficiently different that they complement each other and lead to a higher likelihood of identifying the concealed material.

  8. [Individual differences in analgesic effects of narcotics].

    PubMed

    Ide, Soichiro; Kasai, Shinya; Ikeda, Kazutaka

    2008-02-01

    Narcotic analgesics have been widely used for management of severe pain, especially for cancer pain. Most of these drugs are opioids, and they show their analgesic effects by acting through opioid receptors. Significant individual differences in opioid sensitivity can hamper effective pain treatments and increase side effects, which is associated with decreased quality of life. It is thought that genetic factors may affect individual differences in opioid sensitivity. Recent studies using various inbred and knockout mice have revealed that the mu-opioid receptor (MOP) plays a mandatory role in the analgesic properties of opioids. There is also increasing evidence that differences in the sequence of the MOP gene might significantly affect the amount of MOP gene mRNA expression and sensitivity to opioids. Furthermore, it can be thought that individual differences in opioid sensitivity are caused by genetic differences in not only MOP but other biomolecules, such as endogenous opioid peptides, molecules related with metabolic process and second messenger systems. Rapid advances in this research field are leading to a better understanding of relationships between gene polymorphisms and opioid sensitivities, which, in turn, will allow us to more accurately predict opioid sensitivity and opioid requirements in individual patients.

  9. Narcotics detection using fast-neutron interrogation

    1995-12-31

    Fast-neutron interrogation techniques are being investigated for detection of narcotics in luggage and cargo containers. This paper discusses two different fast-neutron techniques. The first uses a pulsed accelerator or sealed-tube source to produce monoenergetic fast neutrons. Gamma rays characteristic of carbon and oxygen are detected and the elemental densities determined. Spatial localization is accomplished by either time of flight or collimators. This technique is suitable for examination of large containers because of the good penetration of the fast neutrons and the low attenuation of the high-energy gamma rays. The second technique uses an accelerator to produce nanosecond pulsed beams of deuterons that strike a target to produce a pulsed beam of neutrons with a continuum of energies. Elemental distributions are obtained by measuring the neutron spectrum after the source neutrons pass through the items being interrogated. Spatial variation of elemental densities is obtained by tomographic reconstruction of projection data obtained for three to five angles and relatively low (2 cm) resolution. This technique is best suited for examination of luggage or small containers with average neutron transmissions greater than about 0.01. Analytic and Monte-Carlo models are being used to investigate the operational characteristics and limitations of both techniques.

  10. Medicines submitted to narcotics regulations in France, 1992-2007.

    The objective was to study the current narcotics regulations which are the most restrictive regarding prescription and dispensation practice in France, and their evolution over the period 1992-2007. This is an example of regulation in a European member state regarding medicines with a risk of abuse or dependence. Narcotics regulations were studied in the French public health code. Status and indications of medicines concerned were found on the French medicine agency website, and the retrospective part of the study was conducted using the French public statute law website. Seventeen medicines were found. Three were psychotropics and fourteen narcotics. The prescription rules could be different for a given substance according to the route of administration or indication. In 2007, half of the narcotic opioids could be prescribed for 28 days, whereas in 1992, most of them could be prescribed for only 7 days. These results show the adaptation of French narcotics regulations, with the development of medicines indicated in acute or chronic pain treatment or opioid maintenance treatment.

  11. Portable narcotics detector and the results obtained in field tests

    A compact integrated narcotics detection instrument (CINDI) has been developed at NOVA R&D, Inc. with funding provided by the U.S. Coast Guard. CINDI is designed as a portable sensitive neutron backscatter detector which has excellent penetration for thick and high Z compartment barriers. It also has a highly sensitive detection system for backscattered neutrons and, therefore, uses a very weak californium-252 neutron source. Neutrons backscatter profusely from materials that have a large hydrogen content, such as narcotics. The rate of backscattered neutrons detected is analyzed by a microprocessor and displayed on the control panel. The operator guides the detector along a suspected area and displays in real time the backscattered neutron rate. CINDI is capable of detecting narcotics effectively behind panels made of steel, wood, fiberglass, or even lead-lined materials. This makes it useful for inspecting marine vessels, ship bulkheads, automobiles, structure walls or small sealed containers. The strong response of CINDI to hydrogen-rich materials such as narcotics makes it an effective tool for detecting concealed drugs. Its response has been field tested by NOVA, the U.S. Coast Guard and Brewt Power Systems. The results of the tests show excellent response and specificity to narcotic drugs. Several large shipments of concealed drugs have been discovered during these trials and the results are presented and discussed.

  12. The Narcotic Bowel Syndrome: Clinical Features, Pathophysiology and Management

    Narcotic bowel syndrome (NBS) is a subset of opioid bowel dysfunction that is characterized by chronic or frequently recurring abdominal pain that worsens with continued or escalating dosages of narcotics. This syndrome is under recognized and may be becoming more prevalent. This may be due in the United States to increases in using narcotics for chronic non-malignant painful disorders, and the development of maladaptive therapeutic interactions around its use. NBS can occur in patients with no prior gastrointestinal disorder who receive high dosages of narcotics after surgery or acute painful problems, among patients with functional GI disorders or other chronic gastrointestinal diseases who are managed by physicians unaware of the hyperalgesic effects of chronic opioids. The evidence for the enhanced pain perception is based on: a) activation of excitatory anti-analgesic pathways within a bimodal opioid regulation system, b) descending facilitation of pain at the Rostral Ventral Medulla and pain facilitation via dynorphin and CCK activation, and c) glial cell activation that produces morphine tolerance and enhances opioid induced pain. Treatment involves early recognition of the syndrome, an effective physician patient relationship, graded withdrawal of the narcotic according to a specified withdrawal program and the institution of medications to reduce withdrawal effects.

    Adrenocorticotropin (ACTH) acts via a highly selective receptor that is a member of the melanocortin receptor subfamily of type 1 G protein-coupled receptors. The ACTH receptor, also known as the melanocortin 2 receptor (MC2R), is unusual in that it is absolutely dependent on a small accessory protein, melanocortin receptor accessory protein (MRAP) for cell surface expression and function. ACTH is the only known naturally occurring agonist for this receptor. This lack of redundancy and high degree of ligand specificity suggests that antagonism of this receptor could provide a useful therapeutic aid and a potential investigational tool. Clinical situations in which this could be useful include (1) Cushing’s disease and ectopic ACTH syndrome – especially while preparing for definitive treatment of a causative tumor, or in refractory cases, or (2) congenital adrenal hyperplasia – as an adjunct to glucocorticoid replacement. A case for antagonism in other clinical situations in which there is ACTH excess can also be made. In this article, we will explore the scientific and clinical case for an ACTH antagonist, and will review the evidence for existing and recently described peptides and modified peptides in this role.

    Ferriolo, Angela E; Conlon, Helen Acree

    2012-12-01

    Narcotic pain management is currently a topic of concern in the United States; the latest concerns are both legal and ethical. Narcotics are frequently prescribed medications that, when improperly used or supervised, can cause death. Legal concerns include prescribing narcotics without performing detailed health-related evaluations, not recognizing those seeking drugs for personal recreational use, and clients diverting drugs to others for financial gain. Injured workers need to have pain controlled and be mentally safe to perform their job duties. This article identifies types of pain, comorbidities, and alternative methods of pain management beyond narcotic therapy, as well as discusses guidelines used to initiate narcotic therapy when needed.

    We have very little information about the metabolomic changes that mediate neurobehavioral responses, including addiction. It was possible that opioid-induced metabolomic changes in brain could mediate some of the pharmacodynamic effects of opioids. To investigate this, opiate-induced brain metabolomic responses were profiled using a semi-targeted method in C57BL/6 and 129Sv1 mice, which exhibit extreme differences in their tendency to become opiate dependent. Escalating morphine doses (10–40 mg/kg) administered over a 4-day period selectively induced a two-fold decrease (p<0.00005) in adenosine abundance in the brainstem of C57BL/6 mice, which exhibited symptoms of narcotic drug dependence; but did not decrease adenosine abundance in 129Sv1 mice, which do not exhibit symptoms of dependence. Based on this finding, the effect of adenosine on dependence was investigated in genetically engineered mice with alterations in adenosine tone in the brain and in pharmacologic experiments. Morphine withdrawal behaviors were significantly diminished (P<0.0004) in genetically engineered mice with reduced adenosine tone in the brainstem, and by treatment with an adenosine receptor1 (A1) agonist (2-chloro-N6-cyclopentyladenosine, 0.5 mg/kg) or an A2a receptor (A2a) antagonist (SCH 58261 1 mg/kg). These results indicate that adenosine homeostasis plays a crucial role in narcotic drug responses. Opiate-induced changes in brain adenosine levels may explain many important neurobehavioral features associated with opiate addiction and withdrawal. PMID:23098802

  13. Patterns of growth and development in narcotic-exposed children.

    PubMed

    Lifschltz, M H; Wilson, G S

    1991-01-01

    The results of the studies reviewed indicate that intrauterine growth is adversely affected by drug use during pregnancy. Whether the impairment is a direct effect of narcotic exposure or is the result of the interaction of deleterious health, environmental, and socioeconomic factors closely associated with the lifestyle of the woman who abuses drugs cannot be determined at present. Reports on the long-term effects of drug use on growth and intellectual functioning in the offspring of women who abuse drugs are not consistent. While some studies indicate that most of the exposed infants exhibit catchup growth by 6 months of age (Lifschitz et al. 1983, 1985), one methodologically strong study suggests that methadone may have a small direct teratogenic effect reflected in reduced head size at 2 years of age (Hans 1989). Unexplained is the pattern of growth deceleration observed in some narcotic-exposed children (Lifschitz et al. 1983, 1985). The few available reports on long-term outcome concur that narcotic-exposed children have a high incidence of behavioral and learning problems (Strauss et al. 1979; Rosen and Johnson 1985; Wilson 1989), but population studies have been too small to demonstrate that they differ significantly from controls. There is a suggestion that narcotic use during pregnancy promotes a biological vulnerability to adverse environments, manifested in the neurobehavioral and intellectual areas.

    2012-01-01

    The increase in the use of narcotics in Russia has been complicated by the spread of new kinds of drugs that are less visible than more traditional kinds. A worsening of the situation must be prevented. This requires studying the accumulation of world experience, searching for up-to-date approaches to prevention, combining the efforts of science…

    We present the design, fabrication and successful testing of a 14x14x4 mm3 integrated electronic narcotics sensing system which consists of only four parts. The microsystem absorbs airborne narcotics molecules and performs a liquid assay using an integrated quartz crystal microbalance (QCM). A vertically conductive double-sided adhesive foil (VCAF) was used and studied as a novel material for LOC and MEMS applications and provides easy assembly, electrical contacting and liquid containment. The system was tested for measuring cocaine and ecstasy, with successful detection of amounts as small as 100 ng and 200 ng, respectively. These levels are of interest in security activities in customs, prisons and by the police.

    Narcotic medications are the major drug therapy for cancer pain relief. A clinical use of fentanyl patches and oxycodone extended-release tablets has recently become available, which led to more choices of narcotics to be used medically. On the other hand, palliative care systems have not yet been fully established by medical institutions. The management of symptoms including pain, therefore, actually has to be performed by "care doctors" involved in cancer care. We conducted a survey on the medical use of narcotics for 500 people, including cancer patients and their family members. The result showed that the recognition rate of morphine used for cancer pain relief was 88%, while the recognition rate of narcotics for medical use other than morphine available for cancer pain relief was 20%. The most acceptable dosage form of narcotics was a skin patch, followed by an oral preparation. A response percentage that the dosage form of medical narcotics should be selectable by users was 93%.

    A case of gallbladder perforation is presented in which a small bile leak was demonstrated by cholescintigraphy while the patient was receiving meperidine, but not after meperidine was discontinued. The scintigrams obtained during meperidine therapy also showed a pattern of bile-duct obstruction. It is suggested that increased biliary pressure secondary to meperidine admininstration permitted visualization of the leak. Use of narcotic drugs may be a useful pharmocologic intervention in cases of peritonitis due to small obscure bile leaks.

    The World Health Organization has reported that when morphine is used to control pain in cancer patients, psychological dependence is not a major concern. Our studies were undertaken to ascertain the modulation of psychological dependence on morphine under a chronic pain-like state in rats. Morphine induced a dose-dependent place preference. We found that inflammatory and neuropathic pain-like states significantly suppressed the morphine-induced rewarding effect. In an inflammatory pain-like state, the suppressive effect was significantly recovered by treatment with a κ-opioid receptor antagonist. In addition, in vivo microdialysis studies clearly showed that the morphine-induced increase in the extracellular levels of dopamine (DA) in the nucleus accumbens (N.Acc.) was significantly decreased in rats pretreated with formalin. This effect was in turn reversed by the microinjection of a specific dynorphin A antibody into the N.Acc. These findings suggest that the inflammatory pain-like state may have caused the sustained activation of the κ-opioidergic system within the N.Acc., resulting in suppression of the morphine-induced rewarding effect in rats. On the other hand, we found that attenuation of the morphine-induced place preference under neuropathic pain may result from a decrease in the morphine-induced DA release in the N.Acc with a reduction in the μ-opioid receptor-mediated G-protein activation in the ventral tegmental area (VTA). Moreover, nerve injury results in the continuous release of endogenous β-endorphin to cause the dysfunction of μ-opioid receptors in the VTA. This paper also provides a review to clarify misunderstandings of opioid analgesic use to control pain in cancer patients.

  6. A microarray chip for label-free detection of narcotics.

    PubMed

    Klenkar, Goran; Liedberg, Bo

    2008-07-01

    A protein array chip for label-free optical detection of low molecular weight compounds has been developed. As a proof of principle, the chip is proven capable of rapidly (approximately 1 min) determining hits from aqueous cocktails composed of four common narcotics, cocaine, ecstasy, heroin, and amphetamine, using imaging surface plasmon resonance (SPR) as the detection principle. The chip is produced by injecting a mixture of antibodies and letting them self-sort and bind to narcotic analog coupled proteins already present in a predefined pattern on the supporting substrate. An indirect detection method, where antibodies are displaced from the surface upon recognition of their corresponding narcotics, is used to obtain the optical contrast and thus a detectable SPR and/or ellipsometric signal. Two types of readouts are possible from the present setup: intensity SPR images and SPR/ellipsometric sensorgrams. Positive hits were routinely obtained for analyte concentrations of 50 pg/microL and the limit of detection, without any parameter optimizations, seems to fall in the range 0.5 pg/microL (1.4 nM) for heroin, 2.5 pg/microL (8.2 nM) for cocaine, and 5 pg/microL for the other two narcotics (26 nM for ecstasy and 37 nM for amphetamine). With improved readout possibilities (sampling frequency), signal evaluation algorithms, and antibody-antigen design strategies, we believe this limit can be further improved. The chip is shown to work for many measurement cycles with excellent reproducibility. Moreover, with a more advanced fluidic system, excess injected antibodies could be collected and reused for many cycles, which could make the running costs of the system very low. The chip is in no way limited to detection of narcotics. Other low molecular weight compounds could easily be detected on the same chip. For example, trinitrotoluene detection has already been demonstrated using our chip. Possible areas of application for the system are therefore envisaged in airport

    We describe a nuclear technique, the carbon camera, with which we have produced images of elemental carbon in concentrations and with surface densities typical in kilo quantities of narcotics. The signal is all high-energy gamma rays detected in a short time interval after irradiation of a target pixel by photons produced with an electron beam. Our carbon marker, the photoproton reaction on the minority carbon isotope, gives a robust signal with no interfering signals. We describe here the physics of the carbon camera and sketch our efforts to develop the technology of a fieldable instrument.

    An increasingly important need today is to guard against terrorist attacks at key locations such as airports and public buildings. Liquid explosives can avoid detection at security checkpoints by being concealed as beverages or other benign liquids. Magnetic resonance (MR) offers a safe, non-invasive technology for probing and classifying the liquid contents inside sealed non-metallic containers or packages. Quantum Magnetics has developed a Liquid Explosives Screening System or `Bottle Scanner' to screen for liquid explosives and flammables, described at an earlier SPIE conference in 1996. Since then, the Bottle Scanner's performance has been significantly improved by the incorporation of neural network-based liquid classification. Recently we have shown that the incorporation of additional discrimination parameters can further enhance liquid classification. In addition to screening for explosives and flammables, the Bottle Scanner can be effective against chemical agents, many of which contain fluorine or phosphorous, both of which have MR signatures. Finally, we have evidence that the Bottle Scanner may also be able to detect narcotics dissolved in beverages, one of the methods used to smuggle narcotics across international borders. The development of the Bottle Scanner has been funded by the Federal Aviation Administration.

    1997-01-01

    An increasingly popular method of transporting modest quantities of narcotics across international borders is to employ 'swallowers'. These are people who typically enter the country as international airline passengers after swallowing small, water-tight packages of heroin and/or cocaine. Rapid and accurate identification of swallowers in the airport environment poses difficult technical changes. Commonly used medical inspection technologies fall into one of two categories. Either they are unsuitable for widespread use, or they do not provide adequate information. An example of the former is x-ray scanning, while an example of the latter is ultrasonic imaging. Quantum Magnetics has developed a system to screen selected airline passengers for the presence of swallowed narcotics. The system utilizes magnetic resonance, which provides the physical basis for the magnetic resonance imaging systems widely used in the medical community as an alternative to x-rays. The system is currently operational, and laboratory performance testing is complete. Both the design of the system and its performance will be discussed. This work was sponsored in part by the Office of National Drug Control Policy and the US Customs Service.

    The author describes a nuclear technique for imaging carbon and nitrogen concentrations with surface densities characteristics of bulk narcotics and concealed explosives, the Carbon and the Nitrogen Camera. The physics is rooted in the tightly bound carbon-12 nucleus to which its neighboring isobars, nitrogen-12 and boron-12, decay rapidly (11 and 20 ms), mostly to its ground state, by emitting energetic beta particles (E{sub {beta}}{sup max} {approximately} 13 and 17 MeV) all of which produce bremsstrahlung and some yield annihilate radiation. The signal, photons detected in the multiscalar mode, results from the reactions {sup 13}C({gamma},p){sup 12}{Beta} for the bulk narcotics application and {sup 14}N({gamma},2n){sup 12}N and 14N({gamma},2p){sup 12}{Beta} for explosives detection and are initiated by a stepped pulsed electron beam with energy of {approximately} 30 and {approximately} 50 MeV, respectively. Images of 180 {approximately} 5 cm{sup 2} pixels taken in {approximately} 7 seconds will be presented of the carbon in a kilo of cocaine and the nitrogen in 125 grams of SEMTEX.

    BACKGROUND In spite of the increasing trend in opioid abusers worldwide, the prevalence of narcotic bowel syndrome (NBS) is undetermined. We aimed to estimate the prevalence of NBS and other opioid bowel dysfunction (OBD) in opioid abusers in Kerman, southeast Iran. According to the best of our knowledge, this is the first study to assess the prevalence of NBS in opioid abusers. METHODS By referring to addiction treatment centers in Kerman city and in a cross-sectional study, 577 subjects with opium or opioid subtracts abuse were included in our study. A validated questionnaire was used for OBD assessment and diagnosis of NBS was made according to both the presence of chronic abdominal pain despite increasing the opioid dose and ruling out other causes of abdominal pain. SPSS software version 16 was used for data analysis. p value<0.05 was considered as statistically significant. RESULTS Constipation, regurgitation, and heartburn were the most gastrointestinal complaints that were found in 132(22.9%), 123(21.3%) and 91(15.8%) subjects, respectively. Only 16(2.8%) participants fulfilled all the NBS criteria. Simultaneous use of non-narcotic sedative drugs increased the risk of NBS significantly (the odds ratio 3:1 and p=0.049). CONCLUSION NBS is not rare among opioid abusers and should be considered as a cause of chronic abdominal pain in this group. PMID:25349684

    Pain control after traumatic rib fracture is essential to avoid respiratory complications and prolonged hospitalization. Narcotics are commonly used, but adjunctive medications such as nonsteroidal anti-inflammatory drugs may be beneficial. Twenty-one patients with traumatic rib fractures treated with both narcotics and intravenous ibuprofen (IVIb) (Treatment) were retrospectively compared with 21 age- and rib fracture-matched patients who received narcotics alone (Control). Pain medication requirements over the first 7 hospital days were evaluated. Mean daily IVIb dose was 2070 ± 880 mg. Daily intravenous morphine-equivalent requirement was 19 ± 16 vs 32 ± 24 mg (P < 0.0001). Daily narcotic requirement was significantly decreased in the Treatment group on Days 3 through 7 (P < 0.05). Total weekly narcotic requirement was significantly less among Treatment patients (P = 0.004). Highest and lowest daily pain scores were lower in the Treatment group (P < 0.05). Hospital length of stay was 4.4 ± 3.4 versus 5.4 ± 2.9 days (P = 0.32). There were no significant complications associated with IVIb therapy. Early IVIb therapy in patients with traumatic rib fractures significantly decreases narcotic requirement and results in clinically significant decreases in hospital length of stay. IVIb therapy should be initiated in patients with traumatic rib fractures to improve patient comfort and reduce narcotic requirement.

    Introduction: Immunosensor for illicit drugs have gained immense interest and have found several applications for drug abuse monitoring. This technology has offered a low cost detection of narcotics; thereby, providing a confirmatory platform to compliment the existing analytical methods. Methods: In this minireview, we define the basic concept of transducer for immunosensor development that utilizes antibodies and low molecular mass hapten (opiate) molecules. Results: This article emphasizes on recent advances in immunoanalytical techniques for monitoring of opiate drugs. Our results demonstrate that high quality antibodies can be used for immunosensor development against target analyte with greater sensitivity, specificity and precision than other available analytical methods. Conclusion: In this review we highlight the fundamentals of different transducer technologies and its applications for immunosensor development currently being developed in our laboratory using rapid screening via immunochromatographic kit, label free optical detection via enzyme, fluorescence, gold nanoparticles and carbon nanotubes based immunosensing for sensitive and specific monitoring of opiates.

    2014-10-01

    Prescription opioid use for chronic non-cancer pain has reached epidemic levels in the USA. With this increased use is the recognition of serious opioid-related gastrointestinal complications such as narcotic bowel syndrome (NBS) and opioid-induced constipation (OIC). NBS consists of a paradoxical worsening of abdominal pain with escalating doses of opioids and is likely mediated by the central nervous system. Therapy requires an intensive multidisciplinary approach to detoxification. OIC is the most common gastrointestinal side effect of opioids. Several novel therapeutics are available to treat OIC that fails to respond to laxative therapy. This review will summarize recent findings on the pathophysiology and treatment approaches to NBS and OIC with a focus on controversies about diagnosis and intervention.

  14. Muscarinic Receptor Antagonists.

    Parasympathetic activity is increased in patients with chronic obstructive pulmonary disease (COPD) and asthma and appears to be the major reversible component of airway obstruction. Therefore, treatment with muscarinic receptor antagonists is an effective bronchodilator therapy in COPD and also in asthmatic patients. In recent years, the accumulating evidence that the cholinergic system controls not only contraction by airway smooth muscle but also the functions of inflammatory cells and airway epithelial cells has suggested that muscarinic receptor antagonists could exert other effects that may be of clinical relevance when we must treat a patient suffering from COPD or asthma. There are currently six muscarinic receptor antagonists licenced for use in the treatment of COPD, the short-acting muscarinic receptor antagonists (SAMAs) ipratropium bromide and oxitropium bromide and the long-acting muscarinic receptor antagonists (LAMAs) aclidinium bromide, tiotropium bromide, glycopyrronium bromide and umeclidinium bromide. Concerns have been raised about possible associations of muscarinic receptor antagonists with cardiovascular safety, but the most advanced compounds seem to have an improved safety profile. Further beneficial effects of SAMAs and LAMAs are seen when added to existing treatments, including LABAs, inhaled corticosteroids and phosphodiesterase 4 inhibitors. The importance of tiotropium bromide in the maintenance treatment of COPD, and likely in asthma, has spurred further research to identify new LAMAs. There are a number of molecules that are being identified, but only few have reached the clinical development.

  15. Classification of narcotics in solid mixtures using principal component analysis and Raman spectroscopy.

    PubMed

    Ryder, Alan G

    2002-03-01

    Eighty-five solid samples consisting of illegal narcotics diluted with several different materials were analyzed by near-infrared (785 nm excitation) Raman spectroscopy. Principal Component Analysis (PCA) was employed to classify the samples according to narcotic type. The best sample discrimination was obtained by using the first derivative of the Raman spectra. Furthermore, restricting the spectral variables for PCA to 2 or 3% of the original spectral data according to the most intense peaks in the Raman spectrum of the pure narcotic resulted in a rapid discrimination method for classifying samples according to narcotic type. This method allows for the easy discrimination between cocaine, heroin, and MDMA mixtures even when the Raman spectra are complex or very similar. This approach of restricting the spectral variables also decreases the computational time by a factor of 30 (compared to the complete spectrum), making the methodology attractive for rapid automatic classification and identification of suspect materials.

  16. Dispositional, ecological and biological influences on adolescent tranquilizer, Ritalin, and narcotics misuse.

    The primary purpose of this study was to examine the extent to which two of the three sources of risk-taking--dispositional and ecological--in adolescence and demographic variables were related to Ritalin, tranquilizer and narcotics misuse. The secondary aim of this study was to distinguish subgroups of Ritalin, tranquilizer, and narcotics misusers using dispositional, ecological and demographic variables. An archival dataset containing 1672 participants (11-18 years old) was used. Ritalin, tranquilizer, and narcotics misuse were dichotomized and hierarchical logistic regressions were computed for dispositional and ecological sources of risk-taking and demographics. To distinguish subgroups of misusers, hierarchical multinomial regressions were computed. Dispositional, ecological, and demographic variables were related to Ritalin, tranquilizer, and narcotics misuse and distinguished among non-users, experimenters/occasional misusers, and frequent misusers. Prescription drug prevention programs should incorporate demographic, dispositional, and ecological variables and should parallel the guidelines currently used for developing effective substance abuse prevention programs.

    Morphologic signs of narcomania in subjects using primitively prepared narcotics from opium-containing raw material are described. Sites of injections and inflammatory reactions in the parenchymatous organs are described. Special attention is paid to productive hypersensitive inflammation, which can serve as a sign confirming narcomania in subjects using poorly purified narcotic mixture. The authors classify the granulomas in such patients as toxic allergic granulomatosis.

  20. Opposing effects of narcotic gases and pressure on the striatal dopamine release in rats.

    Nitrogen-oxygen breathing mixtures, for pressures higher than 0.5 MPa, decrease the release of dopamine in the rat striatum, due to the narcotic potency of nitrogen. In contrast, high pressures of helium-oxygen breathing mixtures of more than 1-2 MPa induce an increase of the striatal dopamine release and an enhancement of motor activity, referred to as the high pressure nervous syndrome (HPNS), and attributed to the effect of pressure per se. It has been demonstrated that the effect of pressure could be antagonized by narcotic gas in a ternary mixture, but most of the narcotic gas studies measuring DA release were executed below the threshold for pressure effect. To examine the effect of narcotic gases at pressure on the rat striatal dopamine release, we have used two gases, with different narcotic potency, at sublethargic pressure, nitrogen at 3 MPa and argon at 2 MPa. In addition, to dissociate the effect of the pressure, we have used nitrous oxide at 0.1 MPa to induce narcosis at very low pressure, and helium at 8 MPa to study the effect of pressure per se. In all the narcotic conditions we have recorded a decrease of the striatal dopamine release. In contrast, helium pressure induced an increase of DA release. For the pressures used, the results suggest that the decrease of dopamine release was independent of such an effect of the pressure. However, for the same narcotic gas, the measurements of the extracellular DA performed in the striatum seem to reflect an opposing effect of pressure, since the decrease in DA release is lower with increasing pressure.

  1. Physiological and molecular effect assessment versus physico-chemistry based mode of action schemes: Daphnia magna exposed to narcotics and polar narcotics.

    Structural analogues are assumed to elicit toxicity via similar predominant modes of action (MOAs). Currently, MOA categorization of chemicals in environmental risk assessment is mainly based on the physicochemical properties of potential toxicants. It is often not known whether such classification schemes are also supported by mechanistic biological data. In this study, the toxic effects of two groups of structural analogues (alcohols and anilines) with predefined MOA (narcotics and polar narcotics) were investigated at different levels of biological organization (gene transcription, energy reserves, and growth). Chemical similarity was not indicative of a comparable degree of toxicity and a similar biological response. Categorization of the test chemicals based on the different biological responses (growth, energy use, and gene transcription) did not result in a classification of the predefined narcotics versus the predefined polar narcotics. Moreover, gene transcription based clustering profiles were indicative of the observed effects at higher level of biological organization. Furthermore, a small set of classifier genes could be identified that was discriminative for the clustering pattern. These classifier genes covaried with the organismal and physiological responses. Compared to the physico-chemistry based MOA classification, integrated biological multilevel effect assessment can provide the necessary MOA information that is crucial in high-quality environmental risk assessment. Our findings support the view that transcriptomics tools hold considerable promise to be used in biological response based mechanistic profiling of potential (eco)toxicants.

    It is demonstrated that gas chromatography with quartz capillary columns (QCC) and with cross-sewn SE-52 by polysiloxane provides for the possibility to divide and identify, in human urine, 16 narcotic substances of the amphetamine, 1.4-benzodiazepine, morphine and other groups. The suggested extraction method makes it possible to isolate the above compounds from urine simultaneously and, after derivatization, to determine them by gas chromatography (GC) with programmed temperature within one stage analysis session. GC tests were performed on 2 both foreign and Russian QCC with SE-52. There is a description of 2 methods of how to obtain the trifluor-acetyl derivatives (TFA-derivatives) by using trifluor-acetate anhydride and N-methyl-bis-trifluor-acetamide. The limit of detecting the TFA-derivatives was 1-2 ng for the plasma-ionizing detector. The extraction method as well as the positive and negative aspects of using the TFA-derivatives are under discussion. The method of gas-chromatography/mass-spectrometry confirms that the positive results of radioreceptor assay are verified by GC in 92% of cases.

  3. A simple mechanistic model to interpret the effects of narcotics.

    2015-01-01

    In this research we will show the advantages of using a time-independent dose metric in a mechanistic model to evaluate toxic effects for different narcotic compounds on different species. We will show how different already existing QSARs can be combined within a mechanistic framework to 1) make predictions of lethal thresholds; 2) show some limitations in the use of existing QSARs; 3) show how a mechanistic framework solves some conceptual problems in current approaches and 4) show how such a framework can be used to be of aid in an experimental setup in predicting the outcome of a survival experiment. The approach we chose is based on the simplest mechanistic model available, a scaled one-compartment model to describe uptake and elimination and hazard model to link the exposure to effects on survival. Within this theoretical framework a prediction for an internal threshold for effects on survival of 3 mmol/kg bw can be made, which should be similar for different species and independent of the partitioning characteristics of the toxicant. To demonstrate this, a threshold for 51 different species was derived, which indeed appeared to lie in a relatively small range, typically between 1 and 10 mmol/kg bw.

  4. Predictive spatial modeling of narcotic crop growth patterns

    1986-01-01

    Spatial models for predicting the geographic distribution of marijuana crops have been developed and are being evaluated for use in law enforcement programs. The models are based on growing condition preferences and on psychological inferences regarding grower behavior. Experiences of local law officials were used to derive the initial model, which was updated and improved as data from crop finds were archived and statistically analyzed. The predictive models are changed as crop locations are moved in response to the pressures of law enforcement. The models use spatial data in a raster geographic information system. The spatial data are derived from the U.S. Geological Survey's US GeoData, standard 7.5-minute topographic quadrangle maps, interpretations of aerial photographs, and thematic maps. Updating of cultural patterns, canopy closure, and other dynamic features is conducted through interpretation of aerial photographs registered to the 7.5-minute quadrangle base. The model is used to numerically weight various data layers that have been processed using spread functions, edge definition, and categorization. The building of the spatial data base, model development, model application, product generation, and use are collectively referred to as the Area Reduction Program (ARP). The goal of ARP is to provide law enforcement officials with tactical maps that show the most likely locations for narcotic crops.

  6. Advantages of an antagonist: bicuculline and other GABA antagonists

    2013-01-01

    The convulsant alkaloid bicuculline continues to be investigated more than 40 years after the first publication of its action as an antagonist of receptors for the inhibitory neurotransmitter GABA. This historical perspective highlights key aspects of the discovery of bicuculline as a GABA antagonist and the sustained interest in this and other GABA antagonists. The exciting advances in the molecular biology, pharmacology and physiology of GABA receptors provide a continuing stimulus for the discovery of new antagonists with increasing selectivity for the myriad of GABA receptor subclasses. Interesting GABA antagonists not structurally related to bicuculline include gabazine, salicylidene salicylhydrazide, RU5135 and 4-(3-biphenyl-5-(4-piperidyl)-3-isoxazole. Bicuculline became the benchmark antagonist for what became known as GABAA receptors, but not all ionotropic GABA receptors are susceptible to bicuculline. In addition, not all GABAA receptor antagonists are convulsants. Thus there are still surprises in store as the study of GABA receptors evolves. PMID:23425285

    A review of the literature relating to the therapeutic potential of alpha2-adrenoceptor antagonists published between 1990 and 2000 is presented. Although extensively studied since the early 1970s in a wide spectrum of therapeutic applications, the distinction of alpha2-adrenoceptor subtypes and some emerging evidence concerning new applications in neurodegenerative disorders, such as Alzheimer's and Parkinson's diseases, obesity and schizophrenia, have refreshed an interest in this class of agents.

    2003-03-01

    In the pediatric population, control of postoperative pain is a challenging and important issue. We conducted this retrospective study to determine whether single-dose caudal anesthesia administered after club-foot surgery helps to decrease postoperative use of narcotics. Fifty-one patients given an injection of caudal anesthesia (bupivacaine) at completion of clubfoot surgery were compared with 41 patients who did not receive a caudal block. Postoperative pain control was assessed by recording how much narcotic was used by each patient during time in the recovery room and during the first 8 hours after surgery. Results show that a single dose of caudal anesthesia administered at completion of clubfoot surgery is not associated with a statistically significant change in use of narcotics during either postoperative period.

    1981-01-01

    Comparisons are made between ancient ritual uses of the flowers of Nymphaea (Nymphaeaceae) in Maya and Egyptian civilizations. Recurrent motifs encountered in the art of both of these ancient civilizations suggests that the role fo the water lily was that of a narcotic (psychodysleptic) used to mediate ecstasis among a priestly caste. Relevant literature is reviewed as are chemical data. Elements in the complex belief systems of these two civilizations need to be reinterpreted in view of the use of two water lilies as ritual narcotics. The species implicated are Nymphaea caerulea Sav., in Egypt, and N. ampla DC., among the Maya.

    1997-08-01

    This project was supported by LDRD funding for the development and preliminary testing of a portable narcotics detection system. The system developed combines a commercial trace detector known as an ion mobility spectrometer (IMS) with a preconcentrator originally designed by Department 5848 for the collection of explosives molecules. The detector and preconcentrator were combined along with all necessary accessories onto a push cart, thus yielding a fully portable detection unit. Preliminary testing with both explosives and narcotics molecules shown that the system is operational, and that it can successfully detect drugs as marijuana, methamphetamine (speed), and cocaine based on their characteristics IMS signatures.

    1995-07-01

    Fast-neutron inspection techniques show considerable promise for explosive and narcotics detection. A key advantage of using fast neutrons is their sensitivity to low-Z elements (carbon, nitrogen, and oxygen), which are the primary constituents of these materials. We are currently investigating two interrogation methods in detail: Fast-Neutron Transmission Spectroscopy (FNTS) and Pulsed Fast-Neutron Analysis (PFNA). FNTS is being studied for explosives and narcotics detection in luggage and small containers for which the transmission ratio is greater than about 0.01. The Monte-Carlo radiation transport code MCNP is being used to simulate neutron transmission through a series of phantoms for a few (3-5) projection angles and modest (2 cm) resolution. Areal densities along projection rays are unfolded from the transmission data. Elemental abundances are obtained for individual voxels by tomographic reconstruction, and these reconstructed elemental images are combined to provide indications of the presence or absence of explosives or narcotics. PFNA techniques are being investigated for detection of narcotics in cargo containers because of the good penetration of the fast neutrons and the low attenuation of the resulting high-energy gamma-ray signatures. Analytic models and Monte-Carlo simulations are being used to explore the range of capabilities of PFNA techniques and to provide insight into systems engineering issues. Results of studies from both FNTS and PFNA techniques are presented.

    The first step for identification of medicinal plants and their therapeutic effects is to determine their use by local people, traditional medicine books and personal experiences. The aim of this study was to document the medicinal plants used as analgesic, sedative or narcotic agents by local residents of Dehloran, Iran. Interviews conducted with 53 informants (38 male and 15 female) revealed that a total of 32 medicinal plants belonging to 22 families are used in Dehloran as narcotic, sedative and analgesic agents. The most utilized plant families were Asteraceae, Rosaceae and Fabaceae. Approximately 74% of the utilized plants was attributed to herbs, followed by trees (13%) and shrubs (13%). Sixty-six percent of the medicinal plants used in the study area were perennial and the rest were annual or biannual. The most widely used plant parts were flowers (34%) followed by leaves (24%) and fruits (14%). Thirty-nine percent of the medicinal plants were used as sedatives, 39% as analgesics, and 24% as narcotics. Recommended plants in this study can be good candidates for further clinical and laboratory trials on diseases that are associated with pain, suffering, stress and depression. They also can be used to develop new sedative, narcotic and analgesic drugs.

    Novel surface-enhanced Raman scattering (SERS) substrates with high SERS-activity are ideal for novel SERS sensors, detectors to detect illicitly sold narcotics and explosives. The key to the wider application of SERS technique is to develop plasmon resonant structure with novel geometries to enhance Raman signals and to control the periodic ordering of these structures over a large area to obtain reproducible Raman enhancement. In this work, a simple Ar+-ion sputtering route has been developed to fabricate silver nanoneedles arrays on silicon substrates for SERS-active substrates to detect trace-level illicitly sold narcotics. These silver nanoneedles possess a very sharp apex with an apex diameter of 15 nm and an apex angle of 20°. The SERS enhancement factor of greater than 1010 was reproducibly achieved by the well-aligned nanoneedles arrays. Furthermore, ketamine hydrochloride molecules, one kind of illicitly sold narcotics, can be detected down to 27 ppb by using our SERS substrate within 3 s, indicating the sensitivity of our SERS substrates for trace amounts of narcotics and that SERS technology can become an important analytical technique in forensic laboratories because it can provide a rapid and nondestructive method for trace detection.

    Background: Individuals with certain personality disorders, especially the antisocial and borderline personality disorders, are more prone to substance use disorders. Objectives: Regarding the importance of substance use disorders, this study aimed to explore the association between personality disorders and types of used drugs (narcotics and stimulants) in Iranian male substance users. Patients and Methods: The current study was a correlation study. We evaluated 285 male substance users and excluded 25 according to exclusion criteria. A total of 130 narcotic users and 130 stimulant users were recruited randomly in several phases from January 2013 to October 2013. All participants were referred to Substance Dependency Treatment Clinics in Tehran, Iran. Data collection process was accomplished by means of clinical interview based on DSM-V criteria for substance use disorders, Iranian version of addiction severity index (ASI), and Millon clinical multi-axial inventory-III (MCMI-III). Data were analyzed by SPSS 21 using Pearson correlation coefficient and regression, the. Results: There was a significant correlation between stimulant use and histrionic personality disorder (P < 0.001) and antisocial and narcissistic personality disorders (P < 0.05). In addition, correlation between avoidant, histrionic, and narcissistic personality disorders (P < 0.05) and depressed, antisocial, and borderline personality disorders (P < 0.001) with narcotics consumption were significant. In clusters, there was a significant correlation between cluster B personality disorders, and narcotic and stimulants consumption (P < 0.001). In addition, this association was explored between cluster C personality disorder and narcotics (P < 0.001). Conclusions: The results of this study in terms of personality disorders and types of used drugs were in accordance with the previous studies results. It is necessary to design appropriate treatment plans for medical treatment of those with personality

    Chemokines and their receptors are known to play important roles in disease. More than 40 chemokine ligands and 20 chemokine receptors have been identified, but, to date, only two small molecule chemokine receptor antagonists have been approved by the FDA. The chemokine receptor CXCR3 was identified in 1996, and nearly 20 years later, new areas of CXCR3 disease biology continue to emerge. Several classes of small molecule CXCR3 antagonists have been developed, and two have shown efficacy in preclinical models of inflammatory disease. However, only one CXCR3 antagonist has been evaluated in clinical trials, and there remain many opportunities to further investigate known classes of CXCR3 antagonists and to identify new chemotypes. This Perspective reviews the known CXCR3 antagonists and considers future opportunities for the development of small molecules for clinical evaluation.

    By structural modification of piperine, some piperine-based phenylsulfonylhydrazone derivatives exhibited an unprecedented and potent narcotic activity against the oriental armyworm, Mythimna separata (Walker). The ND50 values of compounds 6c and 6e against the third-instar larvae of M. separata, which were more potent than those of wilfortrine and wilforgine, were 0.0074 μmol (after 3.5 h), and 0.0075 μmol (after 7 h) per larvae, respectively. By transmission electron microscope, it demonstrated that mitochondria were vacuolated and swollen in the ganglion cell of M. separata after treatment with 6c. More importantly, 6c selectively displayed the inhibition activity on acetylcholine esterase (AchE) of M. separata. This work paved the way for further studying the insecticidal mechanism of 6c as a new and promising botanical narcotic agent. PMID:26268805

    The rapid, on-site identification of illicit narcotics, such as cocaine, is hindered by the diverse nature of the samples, which can contain a large variety of materials in a wide concentration range. This sample variance has a very strong influence on the analytical methodologies that can be utilized and in general prevents the widespread use of quantitative analysis of illicit narcotics on a routine basis. Raman spectroscopy, coupled with chemometric methods, can be used for in situ qualitative and quantitative analysis of illicit narcotics; however, careful consideration must be given to dealing with the extensive variety of sample types. To assess the efficacy of combining Raman spectroscopy and chemometrics for the identification of a target analyte under real-world conditions, a large-scale model sample system (633 samples) using a target (acetaminophen) mixed with a wide variety of excipients was created. Materials that exhibit problematic factors such as fluorescence, variable Raman scattering intensities, and extensive peak overlap were included to challenge the efficacy of chemometric data preprocessing and classification methods. In contrast to spectral matching analyte identification approaches, we have taken a chemometric classification model-based approach to account for the wide variances in spectral data. The first derivative of the Raman spectra from the fingerprint region (750-1900 cm(-1)) yielded the best classifications. Using a robust segmented cross-validation method, correct classification rates of better than ∼90% could be attained with regression-based classification, compared to ∼35% for SIMCA. This study demonstrates that even with very high degrees of sample variance, as evidenced by dramatic changes in Raman spectra, it is possible to obtain reasonably reliable identification using a combination of Raman spectroscopy and chemometrics. The model sample set can now be used to validate more advanced chemometric or machine learning

    The side effects of narcotics, including morphine, on the visual system are still unclear; therefore, the present study was undertaken to examine the effects of narcotics on the visual system at each antinociceptive dose by using the evoked potential (VEP) in rats. Morphine (2 or 5 mg/kg) caused a significant increase in the amplitude of early and late VEP components (P(1)-N(1), N(1)-P(2), P(3)-N(3) and N(3)-P(4)). Fentanyl (0.02 mg/kg) also showed a significant increase in the amplitude of late VEP components (P(3)-N(3), N(3)-P(4)). The effects of morphine and fentanyl on VEP components were antagonized by naloxone (1 mg/kg). On the other hand, (+/-)-pentazocine (20 mg/kg) reduced the amplitude of the late VEP component (N(3)-P(4)), and this effect was not antagonized by naloxone. Butorphanol showed no significant changes in early and late VEP components. In conclusion, morphine stimulated the retino-geniculate-cortex pathway and the thalamus-cortical circuit through the opioid receptors, and fentanyl stimulated the thalamus-cortical circuit through the opioid receptors. It can therefore be assumed that VEP is a useful tool for examining the side effects of drugs, including narcotics, on the visual system.

    A selective and sensitive screening method for the detection of prohibited narcotic and stimulating agents in doping control is described and validated. This method is suitable for the detection of all narcotic agents mentioned on the World Anti-Doping Agency (WADA) doping list in addition to numerous stimulants. The analytes are extracted from urine by a combined extraction procedure using CH(2)Cl(2)/MeOH (9/1, v/v) and t-butylmethyl ether as extraction solvents at pH 9.5 and 14, respectively. Prior to GC-MS analysis the obtained residues are combined and derivatised with MSTFA. The mass spectrometer is operated in the full scan mode in the range between m/z 40 and 550. The obtained limits of detection (LOD) for all components included in this extensive screening method are in the range 20-500 ng/ml, which is in compliance with the requirements set by WADA. Besides narcotic and stimulating agents, this method is also capable of detecting several agents with anti-estrogenic activity and some beta-agonists. As an example, a positive identification of hydroxyl-methoxy-tamoxyfen is shown.

    In May 2011, numerous poppy plants closely resembling Papaver bracteatum Lindl., a type of narcotic plant that is illegal in Japan, were distributed directly from several large flower shops or through online shopping throughout Japan, including the Tokyo Metropolitan area. In order to better identify the narcotic plants, the relative nuclear DNA content at the vegetative stage was measured by flow cytometric (FCM) analysis in 3 closely-related species of the genus Papaver section Oxytona, namely P. orientale, P. pseudo-orientale, and P. bracteatum, based on the difference between the chromosome numbers of these species. The results showed that the nuclear DNA content differed between these 3 species, and that most of the commercially distributed plants examined in this study could be identified as P. bracteatum. The remaining plants were P. pseudo-orientale, a non-narcotic plant. In addition, the FCM results for the identification of P. bracteatum completely agreed with the results obtained by the morphological analysis, the inter-genic spacer sequence of rpl16-rpl14 (PS-ID sequence) of chloroplast DNA, and the presence of thebaine. These results clearly indicate the usefulness of FCM analysis for the identification of P. bracteatum plants, including when they are in their vegetative stage.

  5. THE ELECTRICAL IMPEDANCE OF MUSCLE DURING THE ACTION OF NARCOTICS AND OTHER AGENTS.

    1. The effect of certain inorganic cations upon the electrical impedance of the sartorius muscle of the frog was investigated. While Na, K, and Mg have little effect upon the resistance of muscle, Ba and Ca cause it to fall. The use of physiologically "unbalanced" salt solution does not in itself seem to affect muscle impedance. 2. The time course of the effect upon muscle impedance of the penetration of substances into the intercellular spaces was studied by treating the muscle with sugar solutions. Half of the effect is over in three-quarters of a minute when the sugar solution is permitted to circulate past both sides of the muscle. This sets an upper limit for the time necessary for inorganic cations and organic narcotics to reach the cell surfaces. The action of inorganic cations and organic narcotics upon muscle is slow compared to the time necessary for them to reach the scene of action. The penetration of the sugar solutions into the intercellular spaces of muscle was found to follow the well known diffusion law, the amount diffusing in being proportional to the square root of the time. Average values of 77.7 per cent for rho, the volume concentration of fibers; 231 ohms specific resistance for r(2), the resistance of the interior of the fibers; and 71.0 degrees for theta, the phase angle of the impedance locus, were obtained for the muscle in Ringer's solution. How these values change when the muscle is placed in various concentrations of sugar was also studied. 3. The action of a number of organic narcotics upon muscle was studied. All decrease 1000 cycle resistance if the concentration is sufficiently high. A detailed analysis of the action of the narcotic, iso-amyl carbamate, was made, and it was noted that low concentrations increase resistance while higher concentrations decrease it. By investigating the effect of narcotics upon muscle impedance over a wide frequency range, it was found that during narcosis the resistance of the fiber membranes first

    This report describes the collaboration between the South Texas Specialized Crimes and Narcotics Task Force (STSCNTF) and Sandia National Laboratories (SNL) in a field test that provided prototype hand-held trace detection technology for use in counter-drug operations. The National Institute of Justice (NIJ)/National Law Enforcement and Corrections Technology Center (NLECTC)/Border Research and Technology Center (BRTC) was contacted by STSCNTF for assistance in obtaining cutting-edge technology. The BRTC created a pilot project for Sandia National Laboratories (SNL) and the STSCNTF for the use of SNL’s Hound, a hand-held sample collection and preconcentration system that, when combined with a commercial chemical detector, can be used for the trace detection of illicit drugs and explosives. The STSCNTF operates in an area of high narcotics trafficking where methods of concealment make the detection of narcotics challenging. Sandia National Laboratories’ (SNL) Contraband Detection Department personnel provided the Hound system hardware and operational training. The Hound system combines the GE VaporTracer2, a hand-held commercial chemical detector, with an SNL-developed sample collection and preconcentration system. The South Texas Task force reported a variety of successes, including identification of a major shipment of methamphetamines, the discovery of hidden compartments in vehicles that contained illegal drugs and currency used in drug deals, and the identification of a suspect in a nightclub shooting. The main advantage of the hand-held trace detection unit is its ability to quickly identify the type of chemical (drugs or explosives) without a long lag time for laboratory analysis, which is the most common analysis method for current law enforcement procedures.

    A Compact Integrated Narcotics Detection Instrument (CINDI) has been developed at NOVA R and D, Inc., in cooperation with the US Coast Guard. This detector utilizes neutrons emitted from {sup 252}Cf. Neutrons emitted from the front face of CINDI penetrate dense compartment barrier materials with little change in energy but are backscattered by hydrogen-rich materials such as drugs. The backscattered neutrons are detected, and the rate is displayed by a microprocessor-controller integrated into CINDI. The operator guides the detector along a suspected area and receives immediate feedback from the state-of-the-art electronics. For user safety, the device incorporates a highly sensitive detection scheme to permit the use of a very weak radioactive source, without compromising detectability. CINDI is capable of detecting narcotics effectively behind panels made of steel, wood, fiberglass, or even lead-lined materials. This makes it useful for inspecting marine vessels, ship bulkheads, automobiles, structure walls, or small sealed containers. Figure 2 shows three views of the CINDI instrument. CINDI responds strongly to hydrogen-rich materials such as narcotics. It has been tested at NOVA, the US Coast Guard, and Brewt Power Systems. The results of the tests show excellent response and specificity to narcotics. CINDI has led to a new technology that shows promise for identifying the concealed contraband. The new technique uses a fusion of two independent but complementary signals for detecting and possibly identifying concealed drugs in a variety of carriers such as vehicles, marine vessels, airplanes, containers, cargo, and luggage. The carriers will be scanned using both neutron and gamma-ray sources. The signal from both the neutron and gamma-ray backscattering and/or transmission can be used simultaneously to detect and possibly identify the contrabands it has been trained for. A system that can produce three-dimensional images for both signals may also be developed

    Illegal substance use is a serious problem all over the world. In order to effectively combat substance abuse it is important that both the particular features of drug users and the culture-specific risk factors that go along with drug abuse be identified. The present study was carried out in Bursa, Turkey, in order to document annual changes in the frequency of felons arrested of narcotics offenses and to establish the socio-demographics of these narcotics felons. Among the 2,230 narcotics felons reviewed, 24.3% had been charged with drug dealing but not consumption (profit-driven felons [PDFs]), 19.0% were narcotics felons charged with both dealing and consumption ([hard core drug users HCDUs]), and 56.7% were narcotics felons charged only with consumption and possession (not so hard core drug users [NHCDUs]). The NHCDUs were younger (< 30 years) than both the HCDUs and PDFs, while most of the PDFs and HCDUs were married. Despite the fact that the male/female ratio of the Bursa population was nearly 1:1 for the past 30 years, 93.0%, 95.0% and 96.0% of the PDFs, HCDUs, and NHCDUs, respectively, were male. It was also found that the most commonly used illicit substance in Bursa over this period of time was cannabis. Over the course of the 30-year period examined, the annual incidence rate of narcotics felons arrested increased from 0.4257 per 10,000 to 1.2389 per 10,000. Determining the socio-demographic characteristics of HCDUs and NHCDUs would be useful in preventing substance use before substance users become addicted.

    Through a cooperative effort between the U. S. Department of Energy and the Russian Federation (RF) Ministry of Defense (MOD) a Personnel Reliability Program (PRP) for the nuclear handlers within the RF MOD has been implemented. A key element in the RF MOD PRP is the detection and confirmation of narcotic use in subject military and civilian personnel. This paper describes the process of narcotics screening and testing in the RF MOD and explains the confirmation process once screening has shown a positive result. Issues of laboratory certification, employee certification, employee training, sample chain-of-custody, and equipment needs will be addressed.

    Iranian crack is a new form of narcotic substance that has found widespread prevalence in Iran in the past years. Crack only nominally resembles crack cocaine as it is widely different in its clinical signs. Thus the present study aims to quantify the chemical combination of this drug. The samples included 18 specimen of Crack collected from different zones of Tehran, Iran. All specimens were in the form of inodorous cream solid powdery substance. TLC and HPLC methods were used to perform semi-quantitative and quantitative analysis of the components, respectively. The TLC analysis showed no cocaine compound in the specimens while they all revealed to contain heroin, codeine, morphine and caffeine. All but two specimens contained thebaine. None of the specimens contained amphetamine, benzodiazepines, tricyclic antidepressants, aspirin, barbiturates, tramadol and buprenorphine. Acetaminophen was found in four specimens. HPLC revealed heroin to be the foundation substance in all specimens and most of them contained a significant amount of acetylcodeine. The present analysis of the chemical combination of Crack showed that this substance is a heroin-based narcotic which is basically different from the cocaine-based crack used in Western countries. Studies like the present one at different time points, especially when abnormal clinical signs are detected, can reveal the chemical combination of the target substance and contribute to the clinical management of its acute or chronic poisoning.

    A simple, sensitive and reproducible method using microemulsion electrokinetic chromatography (MEEKC)-field amplified sample injection (FASI) was developed for the analysis of nine narcotics (morphine, codeine, naloxone, heroin, thebaine, cocaine, pethidine, fentanyl and methadone) in urine. In the MEEKC method, sodium dodecyl sulfate (SDS), 1-butanol and ethyl acetate were used as surfactant, co-surfactant and organic solvent, respectively. The effects of the acidity and concentration of borate buffer, SDS, 1-butanol and ethyl acetate contents were investigated. The optimum concentrations (by mass fraction) of microemulsion system were 0.6% SDS, 1.2% 1-butanol, 0.6% ethyl acetate and 97.6% 10 mmol/L Na2B4O7 buffer (pH 9.5). The applied voltage was 25 kV. FASI was coupled with the MEEKC method to increase the sensitivity. Under the optimum conditions, the nine narcotics were baseline separated within 15 min and the detection limits (S/N = 3) were in the range of 0.3 - 8.0 microg/L. The spiked recoveries in urine samples were between 79.4% and 119.9% with the intraday relative standard deviations (RSDs) less than 5.5%. The developed method has been successfully applied to the analysis of methadone in the samples from in vitro metabolism study.

  12. New, high-efficiency ion trap mobility detection system for narcotics and explosives

    1994-10-01

    A new patented Ion Trap Mobility Spectrometer (ITMS) design is presented. Conventional IMS designs typically operate below 0.1% efficiency. This is due primarily to electric field driven, sample ion discharge on a shutter grid. Since 99.9% of the sample ions generated in the reaction region are lost in this discharge process, the sensitivity of conventional systems is limited. The new design provides greater detection efficiency than conventional designs through the use of an `ion trap' concept. The paper describes the plasma and sample ion dynamics in the reaction region of the new detector and discusses the advantages of utilizing a `field-free' space to generate sample ions with high efficiency. Fast electronic switching is described which is used to perturb the field-free space and pulse the sample ions into the drift region for separation and subsequent detection using pseudo real-time software for analysis and display of the data. Many applications for this new detector are now being considered including the detection of narcotics and explosives. Preliminary ion spectra, reduced mobility data and sensitivity data are presented for fifteen narcotics, including cocaine, THC and LSD are reported.

    The percentage of chiral entities among drug, narcotic drug and psychotropic compounds is steadily increasing. Receptors of the human body recognize the enantiomeric forms of constitutionally identical compounds as entirely different chemical agents. Based upon these facts, this paper reports the percentage of chiral compounds in the various pharmacological classes, and related data. Pertinent terms, such as eutomer, distomer, eudismic index, eudismic affinity quotient are defined. Differences in biological activity between eutomers and distomers are exemplified. The pharmacological classes and subclasses of highest chirality, and the "most chiral" active principles are shown. Some puzzling observations on pharmacological behaviour of stereoisomers are highlighted. The necessity of "racemate switch" in the pharmaceutical industry, and the significance of stereo-specific interactions between the drug, narcotic drug and psychotropic ligands, and complementary, "pocket" moieties of the human body are emphasized. Some features of enantiopharmacology, a fledgling science in the interface of stereochemistry and traditional pharmacology are introduced. The statistical treatment of asymmetric compounds in pharmacological classes and subclasses shows that presently, the percentage of chirality in drug categories is more characteristic of the origin of the compound than its target molecule.

    Objective A new extended-release bupivacaine suspension bupivacaine (ERSB) delivers 3 days of local anesthetic and has been shown to reduce pain and narcotic usage in some patient groups but this issue is largely unstudied in urologic surgery. Material and methods We performed a single-surgeon retrospective chart review of the patients who underwent penile prosthesis implantation. Pain scores and standardized morphine equivalent (ME) dose data were collected during 23 hour- observation period. Subjects who received ERSB were compared with those who received standard bupivacaine or no local anesthesia. Results In a study population of 37 patients, those who received (n=13), and did not receive (n=24) ERSB were grouped, respectively. The groups were comparable demographically. ME was used 3.2 fold more frequently in the non-ERSB group (18.0, and 5.6 for non-ERSB, and ESRB groups, respectively (p=0.04). Mean overall pain scores were 3.8/10 for ERSB and 3.9/10 for non-ERSB group, respectively. Per patient medication cost for the control, and ERSB groups were $5.16 and $285.54, respectively. Conclusion The use of a new ERSB in penile prosthesis implants did lead to reduced narcotic consumption with comparable postoperative pain control to the non-ERSB group. However, the cost of the ERSB ($285/dose) may be prohibitive for its use. PMID:27909614

    This paper presents the toxicity data of 10 nonpolar narcotic chemicals on Pseudokirchneriella subcapitata (green algae) assessed by a new algal toxicity testing technique conducted under air-tight environment. Based on DO production, median effective concentration (EC50) varies from 1.73 mg/L (1-octanol) to 8,040 mg/L (2-propanol). The endpoint of algal growth rate reveals similar sensitivity as that from DO production. Compared to literature data, Pseudokirchneriella subcapitata and Nitrosomonas are apparently more sensitive to nonpolar narcotics than other organisms such as minnow, daphnia, and Tetrahymena pyriformis. Furthermore, good correlations between toxic effects observed from Pseudokirchneriella subcapitata and other aquatic organisms were found. Hence, algal toxicity test can be considered as a surrogate test for estimating the toxicity of nonpolar chemicals to fathead minnow, Microtox, activated sludge, Daphina magna, and Tetrahymena pyriformis. The combined effects of 13 binary mixtures of nonpolar chemicals were investigated using both additive-index method and isobologram analysis. Overall speaking, the joint actions between these chemicals are strictly additive. Model analyses indicate that these compounds act on identical reaction sites or receptors, which verify that these chemicals are of the same toxicity mechanism (narcosis).

    It is not unusual that narcotics-dependent patients fulfill their medical requirements in the emergency department (ED). The behavior of these patients varies, and their manifestations and predictors are still not fully studied. We performed this retrospective study by prospectively collecting data on patients with suspected drug dependence who were undiagnosed at first and then treated for some kind of reported pain at the ED. Patients who were confirmed to have narcotics dependence were compared with control patients in a ratio of 1:3 matching for age, gender, disease, and clinical diagnoses. From January 2006 to October 2009, 26 of 223 patients treated for pain were found to be drug dependent (12 males and 14 females). The average dose of narcotics used was higher than the control group [3.23 ± 1.14 vs. 1.12 ± 0.36, p < 0.001, confidence interval (CI): 1.648-2.583]. Numbers of patients making unscheduled returns to the ED within 24 hours were significant [24/26 vs. 8/78, p ≤ 0.001, odds ratio (OR) 105.00, 95% CI 20.834-529.175]. In addition, patients showing aggressive attitudes were significant (17/26 vs. 2/78, p < 0.001, OR 71.78, 95% CI 14.206-362.663). In the case group, six of them told the physician that they were allergic to medicines other than the particular one they wanted, and three of the six presented injuries that were reported to be in the same (or repeated) place for unscheduled returns, which were not found in the control group. In this study, some behaviors were commonly observed in the at-risk group. These patients were prone to manifest some types of symptoms and behaviors, such as uncontrolled pain with three doses of analgesics, aggressive attitude, returning to the ED within 24 hours with the complaint of the same severe pain, repeating the same injury, claiming allergy to other analgesics, and asking for certain analgesics. All these behaviors should alert the physician to suspect a drug-seeking problem.

    In Victoria (a southern Australian state) in 1995, Narcotics Anonymous had a small but growing membership providing an opportunity to study the early experience of new self-help members. Ninety-one new members were interviewed and 62 (68%) were reinterviewed after 12 months. Three measures of self-help participation were examined: service role involvement, step work, and stable meeting attendance. Lower prior involvement in treatment services and greater participation in self-help predicted subsequent self-help participation. Higher levels of secondary school education predicted service role involvement and longer periods in stable meeting attendance. Higher self-help participation through the 12 months prior to follow-up was associated with lower levels of hazardous alcohol use and higher emotional support at reinterview. Multivariate regression analysis suggested stable self-help meeting attendance and step work continued to predict reductions in hazardous alcohol use and improvements in social support, after controlling for a range of alternative predictors.

    An extension of the "squirming test" is described which makes the method specific for nonnarcotic analgesics. The intraperitoneal injection of acetic acid causes squirming and an increase in capillary permeability that is measured by direct estimation of plasma-bound dye (Pontamine Sky Blue) which has leaked into the peritoneal cavity. Nonnarcotic analgesics inhibit squirming and leakage of dye. Values for the oral ED50s for both effects are given for a number of typical compounds. Narcotic analgesics, in doses that produce analgesia, inhibit squirming but do not significantly affect leakage of dye. Drugs that stimulate the central nervous system and also inhibit squirming have no significant effect on leakage of dye over the range of doses which inhibit squirming. Corticosteroids do not significantly inhibit either squirming or leakage of dye.

    The study was done in 57 psychoactive drug addicts (18 females and 39 males) who entered a methadone maintenance program in Szczecin. The age of participants ranged from 21 to 49 years (mean 32.14 years) and the mean duration of drug abuse as determined during history-taking was 11.6 years. Some of the patients became addicted at the age of just 11 years. The objectives of this work were: a) to apply segmental analysis of hair for studying psychoactive agents and their derivatives in drug abusers during the acute intoxication phase and maintenance therapy; b) to determine if narcotics found in hair matched with findings during history-taking; c) to check the relevance of toxicological tests for psychoactive drug content in hair for monitoring abstinence in maintenance programs. The material consisted of hair sampled from 57 patients who were visited the Outpatient Department for Drug Abusers of the Regional Mental Care Center in Szczecin (Poland). Opioids (morphine, codeine, 6-mono-acetyl-morphine, methadone) were determined using gas chromatography/mass spectrometry (GC/MS-ITD) and a Varian 3400 gas chromatography (USA) coupled to a mass spectrometer (Magnum ionic trapping system, Finnigan Mat, USA). Amphetamines (EP, MK, MA, AMP, MDA, MDMA, MDEA) were analyzed with a liquid chromatography/mass spectrometry (LC/MS) system (LC/MS HP-1100, Hewlett-Packard, USA), equipped with an atmospheric pressure chemical ionization (APCI) chamber and dedicated software. Statistical analysis of the results was done. The following conclusions were drawn: toxicological examination of narcotic content in hair is a useful method for studying the history of drug addiction during the period of time equivalent, to the length of hair. Psychoactive substances detected in hair were in most cases consistent with the history of drug abuse. Analysis of psychoactive substances in hair may be applied for identification of addicting drugs and for abstinence control in therapeutic and

    The ability of morphine to block ovulation in animals prompted investigation of the frequency and mechanisms of menstrual abnormalities in women addicted to narcotic analgesics. Menstrual histories obtained from 76 former heroin addicts receiving daily methadone maintenance revealed that more than one-half of these women had experienced menstrual abnormalities while taking heroin or methadone. In order to determine the specific physiologic effects of narcotic analgesics on reproductive function, detailed endocrinologic studies were carried out in seven of these patients who complained of amenorrhea or irregular menses while receiving methadone. Four of the seven women manifested abnormalities of the control of gonadotropin secretion. Three of these four failed to exhibit cyclic gonadotropin release, as evidenced by an absence of increased levels of follicular phase follicle-stimulating hormone, midcycle gonadotropin peaks or luteal phase progesterone increments. In the fourth patient a prolonged follicular phase (30 days) of the menstrual cycle was detected. One of these four patients also had low basal gonadotropin levels and failed to exhibit luteinizing hormone increments greater than control levels in response to ethinyl estradiol (positive feedback). The remaining three women exhibited normal patterns of gonadotropin secretion during the observation period. In these women, menstrual bleeding occurred in response to withdrawal from luteal phase (10 to 20 ng/ml) progesterone levels and to exogenous ethinyl estradiol, suggesting normal uterine responsivity to progesterone and estrogen. Although not documented, it is likely that oligo-ovulation was the cause of the irregular menses in these three patients. Amenorrhea is commonly associated with methadone ingestion or heroin addiction and appears to be related to an alteration of the hypothalamic mechanisms controlling gonadotropin secretion. Tolerance to these effects of methadone may develop after chronic

    Mineralocorticoid receptor antagonists (MRAs) have become mandated therapy in patients with reduced ejection fraction (systolic) heart failure (HF) across all symptom classes. These agents should also be prescribed in the early post-myocardial infarction setting in those with reduced ejection fraction and either HF symptoms or diabetes. This article explores the pathophysiological role of aldosterone, an endogenous ligand for the mineralcorticoid receptor (MR), and summarizes the clinical data supporting guideline recommendations for these agents in systolic HF. The use of MRAs in novel areas beyond systolic HF ejection is also explored. Finally, the current status of newer agents will be examined.

    Substance P (SP) is an important mediator of pro-inflammatory mechanisms in the skin. It targets multiple cells such as keratinocytes, mast cells, and fibroblasts which are involved in the cutaneous generation of pruritus. This suggests that SP is an interesting target for therapy. In fact, in recent case reports and case series, SP antagonists demonstrated a significant antipruritic effect in acute and chronic pruritus such as drug-induced pruritus, paraneoplastic pruritus, prurigo nodularis, cutaneous T-cell lymphoma, and brachioradial pruritus.

    Warfarin is the most widely used oral anticoagulant in clinical use today. Indications range from prosthetic valve replacement to recurrent thromboembolic events due to antiphospholipid syndrome. In hemodialysis (HD) patients, warfarin use is even more frequent than in the nonrenal population due to increased cardiovascular comorbidities. The use of warfarin in dialysis patients with atrial fibrillation requires particular caution because side effects may outweigh the assumed benefit of reduced stroke rates. Besides increased bleeding risk, coumarins exert side effects which are not in the focus of clinical routine, yet they deserve special consideration in dialysis patients and should influence the decision of whether or not to prescribe vitamin K antagonists in cases lacking clear guidelines. Issues to be taken into consideration in HD patients are the induction or acceleration of cardiovascular calcifications, a 10-fold increased risk of calciphylaxis and problems related to maintaining a target INR range. New anticoagulants like direct thrombin inhibitors are promising but have not yet been approved for ESRD patients. Here, we summarize the nontraditional side effects of coumarins and give recommendations about the use of vitamin K antagonists in ESRD patients.

    The venom of the solitary wasp Philanthus triangulum contains a cholinergic antagonist of the nicotinic receptor of the rectus abdominis muscle of the frog, Xenopus laevis. The venom of African P. triangulum contains two different cholinergic factors, a competitive and a non-competitive antagonist. The venom of the European P. triangulum may not contain a competitive antagonist of the nicotinic receptor of X. laevis, but only a very strong non-competitive antagonist. The possible non-synonymity of both groups of P. triangulum is discussed.

  12. Study to investigate the trace levels of contamination on surfaces when narcotic contraband is concealed in a vehicle

    When a vehicle is used to transport narcotic contraband material trace levels of that material can be found on surfaces of the vehicle, people associated with the vehicle and surface they contact. The detection of these trace levels can help to target vehicles associated with the smuggling of the contraband. A study to determine the typical levels of narcotic material that can be detected from these surfaces has been performed by personnel from Graseby, using a variety of drug materials. The size and packaging of the drug materials has been prepared to try to reflect that typically found in smuggling operations. These tests show that for all hard drugs easily detectable traces of drug material can be found on the vehicle, the proxy and secondary surfaces handled by the proxy. For detection of cannabis, the condition of the original material had a great bearing ont he reliability of detection.

  13. A new alcohol antagonist: Phaclofen

    1989-01-01

    The ability of the GABA{sub B} receptor antagonist, phaclofen to alter behavioral effects of ethanol was evaluated by loss of righting reflex (sleep time), motor incoordination (bar holding), spontaneous locomotion (open field activity) and hypothermia. Pretreatment with phaclofen significantly decreased the effects of ethanol on motor incoordination, locomotor activity and hypothermia. However, phaclofen had no effect on either pentobarbital- or diazepam-induced motor incoordination. Phaclofen slightly increased the ED{sub 50} for loss of the righting reflex but did not alter either the duration of reflex loss produced by ethanol or blood ethanol levels at awakening. Our results suggest phaclofen is rapidly inactivated resulting in difficulty in observing antagonism of long duration ethanol effects. These findings suggest that the GABA{sub B} system may play a role in mediating several important actions of ethanol.

    Validated data regarding HIV-transmission in prisons in developing countries is scarce. We examined sexual and injecting drug use behavior and HIV and HCV transmission in an Indonesian narcotic prison during the implementation of an HIV prevention and treatment program during 2004-2007 when the Banceuy Narcotic Prison in Indonesia conducted an HIV transmission prevention program to provide 1) HIV education, 2) voluntary HIV testing and counseling, 3) condom supply, 4) prevention of rape and sexual violence, 5) antiretroviral treatment for HIV-positive prisoners and 6) methadone maintenance treatment. During a first survey that was conducted between 2007 and 2009, new prisoners entered Banceuy Narcotics Prison were voluntary tested for HIV and HCV-infection after written informed consent was obtained. Information regarding sexual and injecting risk behavior and physical status were also recorded at admission to the prison. Participants who tested negative for both HIV and HCV during the first survey were included in a second survey conducted during 2008-2011. During both surveys, data on mortality among HIV-seropositive patients were also recorded. All HIV-seropositive participants receive treatment for HIV. HIV/ AIDS-related deaths decreased: 43% in 2006, 18% in 2007, 9% in 2008 and 0% in 2009. No HIV and HCV seroconversion inside Banceuy Narcotic Prison were found after a median of 23 months imprisonment (maximum follow-up: 38 months). Total of 484.8 person-years observation was done. Participants reported HIV transmission risk-behavior in Banceuy Prison during the second survey was low. After implementation of HIV prevention and treatment program, no new HIV or HCV cases were detected and HIV-related mortality decreased.

    The changes in effects on motor activity of rats upon repeated (48 day) dosing with four narcotic analgesics were determined. The following were administered IP once daily in a.m.: morphine sulfate (MOR), 20 mg/kg: dl-methadone HCl (MET), 5 mg/kg: meperidine HCl (MEP), 10 mg/kg; and pentazocine lactate (PEN), 20 mg/kg. Motility was measured in photocell actometers every 4 days for 6 hr after dosing. Activity was elevated after the initial dose as follows: for MOR at hours 3-5, for MET at hours 2-5, for MEP and PEN at hours 2-3. Time of peak response showed no systematic change over days. For all 4 drugs there occurred, upon repeated dosing, a considerable increase in motility over the initial acute response. For MOR the greatest increment occurred between days 12 and 16, but regression analysis showed a strong linear trend of increasing activity from day 1 through day 48. For MET and MEP, activity rose considerably between days 4 and 12 to a maximum, after which the activity trended downward for MET, but showed no continuing fall or climb for MEP. For PEN the greatest increases were from days 4 to 8 and 44 to 48, with an intervening period of relative stability. These results seem to be more readily explainable in terms of increasing sensitivity to the motor excitatory actions of these agents than merely by a development of tolerance to motor-inhibitory actions.

    Most research on sentencing outcomes reveals that legally relevant factors such as the seriousness of the offense and prior criminal record are primary determinants. There is, however, a substantial body of research that finds that extralegal factors such as a defendant's sex also influence these outcomes. Most of these latter studies conclude that female defendants receive less severe outcomes compared to their male counterparts. Most of this research, however, is limited to Western societies. To extend this body of research, the current study examines sex differences in sentencing practices for a sample of narcotics offenders in South Korea. Results support previous research; female drug offenders in South Korea are generally treated more leniently than their male counterparts. Tests for interaction effects reveal that the defendant's sex also interacts with other constellations of factors to produce lenient treatment for certain female defendants. These tests, however, also reveal that lenient sentence outcomes are not extended to all female defendants; those with prior drug convictions do not fare better than their male counterparts at the incarceration decision.

    An easy, sensitive and quick method was established for simultaneously separating and determining stimulant, narcotics and antiestrogen in spiked human urine using gas chromatography-nitrogen phosphorous detection (GC-NPD). The urine sample was preprocessed by liquid-liquid extraction. Tert-butyl methyl ether and N-phenylamine were chosen as extraction solvent and internal standard for quantitation, respectively. That is, a standard stock mixture containing methylephedrine, meperidine, methadone, tamoxifen, fentanyl and N-phenylaniline was added into 5.0 mL urine samples and mixed uniformly, then 0.5 mL 5.0 mol/L NaOH, 3.0 g NaCl and 5.0 mL tert-butyl methyl ether were added and finally centrifuged. The extraction solution was dried under N2, redissolved by acetone and then determined by GC-NPD. The )j method showed the satisfactory linearity was between 0.022 - 20 mg/L, with the coefficient correlation from 0.9945 to 0.9998. The detection limits were in the range of 0.007 - 0.015 mg/ L, and the average recoveries in spiked urine were between 75.8% - 118.2% and the relative standard deviations were lower than 17.2%.

    Pure nuclear quadrupole resonance (NQR) of 14N nuclei is quite promising as a method for detecting explosives such as RDX and contraband narcotics such as cocaine and heroin in quantities of interest. Pure NQR is conducted without an external applied magnetic field, so potential concerns about damage to magnetically encoded data or exposure of personnel to large magnetic fields are not relevant. Because NQR frequencies of different compounds are quite distinct, we do not encounter false alarms from the NQR signals of other benign materials. We have constructed a proof-of-concept NQR explosives detector which interrogates a volume of 300 liters (10 ft3). With minimal modification to the existing explosives detector, we can detect operationally relevant quantities of (free base) cocaine within the 300-liter inspection volume in 6 seconds. We are presently extending this approach to the detection of heroin base and also examining 14N and 35,37Cl pure NQR for detection of the hydrochloride forms of both materials. An adaptation of this NQR approach may be suitable for scanning personnel for externally carried contraband and explosives. We first outline the basics of the NQR approach, highlighting strengths and weaknesses, and then present representative results for RDX and cocaine detection. We also present a partial compendium of relevant NQR parameters measured for some materials of interest.

  20. On analgesic and narcotic plants: Pliny and his Greek sources, the history of a complex graft.

    2014-01-01

    Grafting is an important concept in the study of Pliny the Elder, who is a compiler of written sources. We intend to examine how this grafting works in Pliny's discussion of analgesic and narcotic plants, especially the most famous: opium poppy, henbane, mandrake, and hound's berry. We will study Pliny's use of Greek sources and ask how he took up his predecessors' works while integrating the changes that took place during the centuries in the diagnosis and treatment of pain. This cultural graft remains elusive because we do not have access to all of Pliny's Greek sources. When Pliny speaks about these plants, he sometimes copies out information, adding or removing details, and occasionally makes significant mistakes. The graft was particularly difficult in this case because these analgesic plants were considered so special and poisonous that they were sometimes rejected or even condemned. Nevertheless, we can say that this cultural graft succeeded, despite some obstacles, because Pliny assimilated and adapted these old Greek materials to his own time, society, and project.

    We have previously reported that centrally acting non-narcotic antitussives inhibited G protein-coupled inwardly rectifying potassium (GIRK) channel-activated currents, and that the antitussives had multiple pharmacological actions on various models of intractable brain diseases in rodents. In this study, the question of whether these antitussives inhibit drug-induced hyperactivity in mice was investigated. Antitussives, such as cloperastine and tipepidine, at cough suppressant doses, inhibited an increase in ambulation of mice neonatally treated with 6-hydroxydopamine. In addition, all antitussives studied inhibited an increase in methamphetamine-induced hyperactivity in mice. Methylphenidate, which is used for treatment of ADHD, inhibited 6-hydroxydopamine-lesion-induced, but not methamphetamine-induced, hyperactivity in mice. By the rota-rod test, the drugs had little effect on motor coordination of the hyperactive mice. Significant correlation was found between the ameliorating effects of antitussives on methamphetamine-induced hyperactivity and their inhibitory actions on GIRK channel currents (coefficient factor, 0.998). Furthermore, tertiapin, a GIRK channel blocker, prevented an increase in methamphetamine-induced hyperactivity of mice. These results demonstrated that antitussive drugs (cloperastine, tipepidine and caramiphen) possessing inhibitory action on GIRK channels inhibit drug-induced hyperactivity in mice, suggesting that such antitussives may potentially be therapeutic for patients with ADHD.

  2. Antianginal Actions of Beta-Adrenoceptor Antagonists

    PubMed Central

    2007-01-01

    Angina pectoris is usually the first clinical sign of underlying myocardial ischemia, which results from an imbalance between oxygen supply and oxygen demand in the heart. This report describes the pharmacology of β-adrenoceptor antagonists as it relates to the treatment of angina. The β-adrenoceptor antagonists are widely used in long-term maintenance therapy to prevent acute ischemic episodes in patients with chronic stable angina. Beta-adrenoceptor antagonists competitively inhibit the binding of endogenous catecholamines to β1-adrenoceptors in the heart. Their anti-ischemic effects are due primarily to a reduction in myocardial oxygen demand. By decreasing heart rate, myocardial contractility and afterload, β-adrenoceptor antagonists reduce myocardial workload and oxygen consumption at rest as well as during periods of exertion or stress. Predictable adverse effects include bradycardia and cardiac depression, both of which are a direct result of the blockade of cardiac β1-adrenoceptors, but adverse effects related to the central nervous system (eg, lethargy, sleep disturbances, and depression) may also be bothersome to some patients. Beta-adrenoceptor antagonists must be used cautiously in patients with diabetes mellitus, peripheral vascular disease, heart failure, and asthma or other obstructive airway diseases. Beta-adrenoceptor antagonists may be used in combination with nitrates or calcium channel blockers, which takes advantage of the diverse mechanisms of action of drugs from each pharmacologic category. Moreover, concurrent use of β-adrenoceptor antagonists may alleviate the reflex tachycardia that sometimes occurs with other antianginal agents. PMID:17998992

    The Red Queen hypothesis proposes that coevolution of interacting species (such as hosts and parasites) should drive molecular evolution through continual natural selection for adaptation and counter-adaptation1–3. Although the divergence observed at some host-resistance4–6 and parasite-infectivity7–9 genes is consistent with this, the long time periods typically required to study coevolution have so far prevented any direct empirical test. Here we show, using experimental populations of the bacterium Pseudomonas fluorescens SBW25 and its viral parasite, phage Φ2 (refs 10, 11), that the rate of molecular evolution in the phage was far higher when both bacterium and phage coevolved with each other than when phage evolved against a constant host genotype. Coevolution also resulted in far greater genetic divergence between replicate populations, which was correlated with the range of hosts that coevolved phage were able to infect. Consistent with this, the most rapidly evolving phage genes under coevolution were those involved in host infection. These results demonstrate, at both the genomic and phenotypic level, that antagonistic coevolution is a cause of rapid and divergent evolution, and is likely to be a major driver of evolutionary change within species.

    The research community has increasingly focused on the development of OPRK antagonists as pharmacotherapies for the treatment of depression, anxiety, addictive disorders and other psychiatric conditions produced or exacerbated by stress. Short-acting OPRK antagonists have been recently developed as a potential improvement over long-acting prototypic ligands including nor-BNI and JDTic. Remarkably the short-acting LY2456302 is undergoing phase II clinical trials for the augmentation of the antidepressant therapy in treatment-resistant depression. This Letter reviews relevant chemical and pharmacological advances in the identification and development of OPRK antagonists.

    Mineralocorticoid receptor (MR) antagonism is a well-established treatment modality for patients with hypertension, heart failure, and left ventricular systolic dysfunction (LVSD) post-myocardial infarction (MI). There are emerging data showing potential benefits of MR antagonists in other cardiovascular conditions. Studies have shown association between MR activation and the development of myocardial fibrosis, coronary artery disease, metabolic syndrome, and cerebrovascular diseases. This review examines the preclinical and clinical data of MR antagonists for novel indications including heart failure with preserved ejection fraction (HFPEF), pulmonary arterial hypertension (PAH), arrhythmia, sudden cardiac death, valvular heart disease, metabolic syndrome, renal disease, and stroke. MR antagonists are not licensed for these conditions yet; however, emerging data suggest that indication for MR antagonists are likely to broaden; further studies are warranted.

    For more than two decades, the International Narcotic Control Board (INCB) has tried to stop harm reduction and its HIV prevention programs. This posture is based on a fundamental misunderstanding of their responsibilities and of drug addiction itself – i.e. as a public health and clinical care matter made criminal by decree. A recent focal point for the Board's action has been rejecting the use of supervised injection facilities to reduce morbidity and mortality of drug injectors. They single out individual countries and attempt to bully them into rejecting such programs under the banner of the United Nations (falsely) and in the name of international treaties. Their unrelenting and unjustified badgering of signatories to the international treaties that established the INCB is not only unjustified; it is an affront to one of the core purposes of the Board itself: to ensure adequate medical supplies and safe use of controlled substances. The INCB's ill-conceived obsession with intravenousaddiction as a crime flies in the face of the medical view and policies of the World Health Organization and the universally endorsed principles of the General Assembly of the United Nations. The latest target of the INCB is North America's only supervised injection facility, Insite, located in the inner city of Vancouver, Canada. Using the power of their office to meddle in matters of public health for individual nations is without medical, scientific or legal justification. But, most importantly, it is a matter of lifeand death for these most marginalized of citizens. The empirical evidence remains that a significant portion of the continued growth of the AIDS pandemic is due to injecting drug use, and the INCB's intrusion will inevitably result in additional deaths due to preventable HIV infections and drug overdoses. So we are very pleased to call to our readers' attention to a recent report produced by the Canadian HIV/AIDS Legal Network and the International Harm Reduction

  9. Desorption electro-flow focusing ionization of explosives and narcotics for ambient pressure mass spectrometry.

    Forbes, Thomas P; Brewer, Tim M; Gillen, Greg

    2013-10-07

    Desorption electro-flow focusing ionization (DEFFI), a desorption-based ambient ion source, was developed, characterized, and evaluated as a possible source for field deployable ambient pressure mass spectrometry (APMS). DEFFI, based on an electro-flow focusing system, provides a unique configuration for the generation of highly charged energetic droplets for sample analysis and ionization. A concentrically flowing carrier gas focuses the liquid emanating from a capillary through a small orifice, generating a steady fluid jet. An electric field is applied across this jet formation region, producing high velocity charged droplets that impinge on an analyte laden surface. This configuration separates the jet charging region from the external environment, eliminating detrimental effects from droplet space charge or target surface charging. The sample desorption and ionization processes operate similar to desorption electrospray ionization (DESI). DEFFI demonstrated strong signal intensities and improved signal-to-noise ratios in both positive and negative mode mass spectrometry for narcotics, i.e., cocaine, and explosives, i.e., cyclotrimethylenetrinitramine (RDX), respectively. A characterization of DEFFI ionization mechanisms identified operation regimes of both electrospray and corona discharge based analyte ionization, as well as limitations in overall signal. In addition, the DEFFI response was directly compared to DESI-MS under similar operating conditions. This comparison established a wider and more stable optimal operating range, while requiring an order of magnitude lower applied gas pressure and applied potential for DEFFI than DESI. These reductions are due to the physical mode of jet formation and geometric configuration differences between DEFFI and DESI, pointing to a potential benefit of DEFFI-MS for field implementation.

    Quantification of visual function is essential for the impact of disease models and their treatment. Recently, we introduced a chronic implant model to record visual evoked potentials (VEP) in awake Brown-Norway rats. Here, we investigated the hemispheric distribution of VEP after monocular stimulation, the chronic electrode implantation and the influence of commonly used anesthetics. Potentials were recorded by electrodes, implanted epidurally over the superior colliculus. The entire visual field of the rat was stimulated. Flicker stimuli were modulated in luminance with a modulation depth from 5 to 80% at 7.5 Hz and flashes with a modulation depth of >95% in a frequency range of 2.9-38 Hz. Recordings were constant over 9 days. When one eye was blinded, the potentials recorded from the contralateral side were not affected, while the potentials of the ipsilateral side were markedly reduced. Further, potentials of awake animals were compared with those receiving general anesthetics. For one group of rats (n = 8), we administered isoflurane by inhalation in five concentrations. Four different groups (n = 7-11) were given choralhydrate (200 and 400 mg/kg) and the combination of ketamine/xyaline (65/7 or 130/14 mg/kg, respectively) intraperitoneally. Isoflurane depressed the VEP in a concentration-dependent manner. Treatment with chloralhydrate and ketamine/xyaline increased the VEP at low concentrations and depressed it in high concentrations. The new VEP paradigm assesses distinct qualities of contrast vision in rats. All tested narcotics alter VEP amplitudes and can be avoided.

    Laudien, Robert; Schultze, Rainer; Wieser, Jochen

    2010-10-01

    In this contribution two analytical devices for the fast detection of security-relevant substances like narcotics and explosives are presented. One system is based on an ion trap mass spectrometer (ITMS) with single photon ionization (SPI). This soft ionization technique, unlike electron impact ionization (EI), reduces unwanted fragment ions in the mass spectra allowing the clear determination of characteristic (usually molecular) ions. Their enrichment in the ion trap and identification by tandem MS investigations (MS/MS) enables the detection of the target substances in complex matrices at low concentrations without time-consuming sample preparation. For SPI an electron beam pumped excimer light source of own fabrication (E-Lux) is used. The SPI-ITMS system was characterized by the analytical study of different drugs like cannabis, heroin, cocaine, amphetamines, and some precursors. Additionally, it was successfully tested on-site in a closed illegal drug laboratory, where low quantities of MDMA could be directly detected in samples from floors, walls and lab equipments. The second analytical system is based on an ion mobility (IM) spectrometer with resonant multiphoton ionization (REMPI). With the frequency quadrupled Nd:YAG laser (266 nm), used for ionization, a selective and sensitive detection of aromatic compounds is possible. By application of suited aromatic dopants, in addition, also non-aromatic polar compounds are accessible by ion molecule reactions like proton transfer or complex formation. Selected drug precursors could be successfully detected with this device as well, qualifying it to a lower-priced alternative or useful supplement of the SPI-ITMS system for security analysis.

Like that earlier Inquisition of 1633 that convicted Galileo of heresy for holding that the sun is the centre of the universe with the earth revolving around it (in contradiction to church doctrine of the time) the INCB and its thirteen-member panel, now rails against any evidence out of sync with the established doctrine of the war on drugs--particularly those innovations in public health called harm reduction. The latest healthcare and harm reduction practices to attract the ire of the INCB Inquisition are elements of Canada's most effective and innovative measures to minimize the harms of drugs in Vancouver--supervised injection facilities and, recently, the potential establishment of supervised inhalation rooms--along with the long established practice of providing safer mouthpieces for pulmonary inhalation in British Columbia. This is particularly significant as it comes in the midst of a crucial battle between municipal and provincial authorities in BC with the federal government in Ottawa, which seems determined to undermine all the most effective HR programs that are the result of years of steady local and governmental support in Vancouver and now threatens to derail all these programs and spread doubt about their usefulness despite the overwhelmingly positive findings of serous research.

    Calcium antagonists are effective in hypertensive patients of all ethnic groups, irrespective of age, dietary salt intake, salt-sensitivity status or plasma renin activity profile. Some prospective studies show that the calcium antagonists, nifedipine GITS and nitrendipine, reduce cardiovascular morbidity and mortality at least to the same extent as the diuretics. Other prospective studies are in progress to evaluate the effect of calcium antagonists on cardiovascular morbidity and mortality, and the progression of atherosclerosis in hypertensive patients. Calcium antagonists, especially the highly lipophilic amlodipine, lacidipine and nisoldipine, are shown to possess antioxidant properties. These drugs reduce the oxidation of LDL and its influx into the arterial wall, and reduce atherosclerotic lesions in animals. Platelet production of malondialdehyde, a marker of oxygen free radical formation, is suppressed by amlodipine, lacidipine or nifedipine in hypertensive patients. New evidence from long-term clinical trials of calcium antagonists indicates that these drugs can reduce the rate of progression of atherosclerosis in hypertensive and coronary heart disease patients. In the Regression Growth Evaluation Statin Study (REGRESS), co-administration of calcium antagonist, amlodipine or nifedipine with pravasatin caused a significant reduction in the appearance of new angiographic lesions. In the Verapamil in Hypertension and Atherosclerosis Study (VHAS), verapamil was more effective than chlorthalidone in promoting regression of thicker carotid lesions in parallel with a reduction in the incidence of cardiovascular events. In the Prospective Randomized Evaluation of the Vascular Effects of Norvasc Trial (PREVENT), amlodipine slowed the progression of early coronary atherosclerosis in patients with coronary artery disease. In a subprotocol of the Intervention as a Goal in the Hypertension Treatment (INSIGHT) study, nifedipine GITS significantly decreased intima

  18. Embryo implantation and GnRH antagonists: embryo implantation: the Rubicon for GnRH antagonists.

    2000-06-01

    When gonadotrophin-releasing hormone (GnRH) was discovered, the agonist and antagonist of GnRH were developed to control the release of FSH and LH by the gonadotrophs. More than 10 years of research were needed to develop a GnRH antagonist free of histamine release. Recent studies have shown that these GnRH antagonists are effective in preventing a rise in LH during ovarian stimulation in IVF. However, a decrease in ongoing pregnancies seems to suggest that implantation rates per transferred embryo are reduced in GnRH antagonist-stimulated cycles. In my opinion, these data highlight an area less well known to clinicians: the role of the GnRH antagonist at the cellular level in extrapituitary tissues. There are sufficient data in the literature suggesting that GnRH antagonist is an inhibitor of the cell cycle by decreasing the synthesis of growth factors. Given that, for folliculogenesis, blastomere formation and endometrium development, mitosis is everything; the interaction between the GnRH antagonist and the GnRH receptor (present in all these cells and tissues) may compromise the mitotic programme of these cells. This is the Rubicon for the GnRH antagonist: to demonstrate irrevocably that, at the minimal doses necessary to suppress LH release, it does not affect processes such as implantation, embryo development and folliculogenesis.

    A simple, rapid and sensitive CE-ESI-MS method for the simultaneous analysis of seven stimulants and narcotics (amphetamine, ephedrine, methadone, pethidine, tetracaine, codeine and heroin) was developed. The CE-ESI-MS experimental conditions were optimized as follows: 20 mmol/L ammonium acetate with pH 9.0 as running buffer, the separation voltage of 22 kV and the sheath liquid of isopropanol/water (1:1 v/v) containing 7.5 mmol/L acetic acid with 3.0 μL/min flow rate. Under the optimized conditions, the stimulants and narcotics were well separated within 4.6 min using a 70-cm length fused-silica capillary (50 μm id). The detection limits (S/N=3) of the CE-ESI-MS analysis were in the range of 0.40-1.0 ng/mL. Method repeatability of intra-day and inter-day was satisfactory. The recoveries obtained from the analysis of spiked urine samples were between 84.1 and 108%. The developed method was successfully applied for the simultaneous analysis of methadone, pethidine and codeine and their in vitro metabolites.

    This research has focused on the birthing experience of first-time mothers who received the narcotic analgesic combination of Pethidine and Hydroxyzine during the first stage of labour. A qualitative research methodology was used to collect data. Unstructured interviews were held with first-time mothers to obtain accounts of their experience of childbirth. These narrations were audio-taped while the participants were still being cared for in the postnatal ward of the hospital where delivery took place. Nine interviews were conducted with first-time mothers who gave birth normally vaginally after a normal pregnancy and who received a narcotic analgesic in the first stage of labour. The transcribed interviews were analyzed using Tesch's method of descriptive analysis (in Creswell, 1994:115). Four themes with sub-themes emerged from the analysis. The participants reported on the physical experience of labour and described experiencing a lot of pain for which analgesics were given. They also described how these drugs dulled the pain but made them sleepy and unable to cooperate with the midwives. They described their emotional experiences, which included joy and happiness as well as anxiety, anger and despondence. They also reported that they were not sufficiently informed about labour and child-birth. In the last theme they described the methods they used to help them cope with labour including distracting techniques, leaning on a supportive person or praying. Guidelines to help midwives overcome these problems were developed.

    Opioid narcotics are used for the treatment of moderate-to-severe pain and primarily exert their analgesic effects through μ receptors. Although traditional μ agonists can cause undesired side effects, including tolerance, addition of δ antagonists can attenuate said side effects. Herein, we report 4a,9-dihydroxy-7a-(hydroxymethyl)-3-methyl-2,3,4,4a,5,6-hexahydro-1H-4,12-methanobenzofuro[3,2-e]isoquinolin-7(7aH)-one (UMB 425) a 5,14-bridged morphinan-based orvinol precursor synthesized from thebaine. Although UMB 425 lacks δ-specific motifs, conformationally sampled pharmacophore models for μ and δ receptors predict it to have efficacy similar to morphine at μ receptors and similar to naltrexone at δ receptors, due to the compound sampling conformations in which the hydroxyl moiety interacts with the receptors similar to orvinols. As predicted, UMB 425 exhibits a mixed μ agonist/δ antagonist profile as determined in receptor binding and [(35)S]GTPγS functional assays in CHO cells. In vivo studies in mice show that UMB 425 displays potent antinociception in the hot plate and tail-flick assays. The antinociceptive effects of UMB 425 are blocked by naloxone, but not by the κ-selective antagonist norbinaltorphimine. During a 6-day tolerance paradigm, UMB 425 maintains significantly greater antinociception compared to morphine. These studies thus indicate that, even in the absence of δ-specific motifs fused to the C-ring, UMB 425 has mixed μ agonist/δ antagonist properties in vitro that translate to reduced tolerance liabilities in vivo.

    Background Addiction is the repeated use of a chemical substance which affects the biological function of the brain and endangers physical health of the addicted person. Prevalence and pattern of taking drugs were assessed in the current study in a Special Cares Trauma Center. So the specialized physician could manage the medical procedure more easily through identification of addicted patients and type of their narcotics. Methods This cross-sectional study was conducted on 545 patients admitted to the Special Cares Center of Shahid Bahonar Hospital, Kerman, Iran, during 2010-2012. The data were collected by special information collection forms and then analyzed using SPSS software. Findings Among the total studied samples, around 55% of admitted patients were addicts. Opium was the most frequently used narcotic among the addicted patients with a percentage of 62%. Smoking was the most common method of taking the narcotics. 90% of addicted persons were male and 95% of them held diploma and under-diploma educational degrees. Among the reasons for admission of addicted patients to the Special Cares Clinic of Trauma Center, head trauma was the dominant cause (51%). Conclusion Addiction is considerably more prevalent among the population admitted to the Special Cares Center compared to the society, indicating greater vulnerability of addicted individuals in the society. Addiction to traditional and indigenous drugs are still the most prevalent, and fortunately, these drugs are easier to substitute and medicate compared to the new industrial narcotics. PMID:24494137

Risk management experiences in this respect in a large-scale Joint Commission International (JCI)-accredited academic medical center hospital in the People's Republic of China during 2011-2015, focusing on organizational, educational, motivational, and information technological measures in storage, prescribing, preparing, dispensing, administration, and monitoring of medication are summarized. The intensity of use of meperidine in hospitalized patients in 2015 was one-fourth that in 2011. A 100% implementation rate of standard storage of narcotics has been achieved in the hospital since December 2012. A "Plan, Do, Check, Act" cycle was efficient because the ratio of number of inappropriate narcotics prescriptions to total number of narcotics prescriptions for inpatients decreased from August 2014 to December 2014 (28.22% versus 2.96%, P=0.0000), and it was controlled below 6% from then on. During the journey to good pain management ward accreditation by the Ministry of Health, People's Republic of China, (April 2012-October 2012), the medical oncology ward successfully demonstrated an increase in the pain screening rate at admission from 43.5% to 100%, cancer pain control rate from 85% to 96%, and degree of satisfaction toward pain nursing from 95.4% to 100% (all P-values <0.05). Oral morphine equivalent dosage in the good pain management ward increased from 2.3 mg/patient before June 2012 to 54.74 mg/patient in 2014.

    In the membrane of an organism that dies due to exposure to narcotic chemicals, the main phase transition temperature (T{sub tr}) of the phospholipids is decreased and the fluidity is increased. The decrease in T{sub tr} depends on the molar concentration of narcotics in the membrane (membrane burden) and is irrespective of the physicochemical properties of the chemicals. If membrane-water partition coefficients, exposure concentrations, and the amount of lipid in the system are known, membrane burdens of narcotic chemicals can be calculated and compared to membrane burdens that yield toxicity. The partition coefficients of a series of chlorobenzenes between phospholipid vesicles and water (K{sub mw}) were measured at different temperatures in a new experimental set-up. K{sub mw}`s were higher in the liquid-crystalline phase than in the gel phase. Partitioning into the el phase was entropy driven, partitioning into the liquid-crystalline phase was driven by entropy and enthalpy. The fluidity change in phospholipid vesicles, after accumulation of chlorobenzenes, was measured from the change in T{sub tr}. The membrane burdens of various chlorobenzenes needed for a lowering of T{sub tr} were comparable (e.g., 20--60 mmol/kg for a decrease of 1.0 C). The membrane burden needed in vivo for lethality by narcotic chemicals such as chlorobenzenes was calculated to be 40--160 mmol/kg membrane. By combining the in vivo and in vitro data, it can be concluded that in organisms that die due to exposure to narcotic chemicals, the fluidity of the membrane is increased.

    A new screening procedure for 18 narcotics in urine for anti-doping purposes has been developed using liquid chromatography/triple quadrupole mass spectrometry (LC/MS). Electrospray ionization (ESI) was used as interface. Infusion experiments were performed for all substances to investigate their mass spectrometric behaviour in terms of selecting product specific ions. These product ions were then used to develop a tandem mass spectrometric method using selected reaction monitoring (SRM). For the LC/MS analysis, chromatography was performed on an octadecylsilane column. The total run time of the chromatographic method was 5.5 min. For the sample preparation prior to LC/MS analysis, the urine samples were liquid-liquid extracted at pH 9.5 after overnight enzymatic hydrolysis. Two extraction solvents were evaluated: dichloromethane/methanol 9/1 (v/v), which is currently used for the extraction of narcotics, and diethyl ether, used for the extraction of steroids. With diethyl ether the detection limits for all compounds ranged between 0.5 and 20 ng/mL and with the mixture containing dichloromethane the detection limits ranged between 0.5 and 10 ng/mL. Taking into account the minimum required performance limits of the World Anti-Doping Agency of 200 ng/mL for narcotics, diethyl ether can also be considered as extraction solvent for narcotics. Finally, the described method was applied to the analysis of urine samples previously found to contain narcotics by our routine gas chromatography/mass spectrometry (GC/MS) method.

    The acute and chronic bacterial toxicity of 34 organic compounds comprising 19 baseline narcotics and 15 epoxides has been determined with regard to 30-min bioluminescence and 24-h growth inhibition in terms of EC50 (effective concentration 50%) values employing Vibrio fischeri. For the narcotics, linear regression of log EC50 on log Kow (octanol/water partition coefficient) yields r2 (squared correlation coefficient) and rms (root-mean-square error) values of 0.95 and 0.44 (30-min), and 0.94 and 0.34 (24-h), respectively. Employing the resultant baseline narcosis models, toxicity enhancement (Te) values were derived as a ratio of narcosis-predicted over experimental EC50 for the epoxides. For seven aliphatic epoxides, log Te was below 1 in both assays, indicating narcosis-range toxicity with regard to 30-min bioluminescence and 24-h growth inhibition. Concerning eight nonaliphatic epoxides, log Te values up to 2.4 were observed, reflecting excess toxicity through an enhanced electrophilic reactivity of the compounds. Here, however, the intercorrelation between both assays was very low (r2 = 0.09). The results are discussed in terms of electronic substituent effects activating an SN2-type epoxide reaction with nucleophilic protein sites and side-chain activation offering alternative electrophile-nucleophile reaction routes at side-chain sites, leading to respective structural alerts as indicators of excess toxicity. Surprisingly, 30-min bioluminescence appears to be slightly more sensitive to chemical stress than 24-h growth, which holds both for baseline narcotics and for most of the epoxides. This is also reflected by effective narcosis doses 50%, ED50, of 7.1 mmol/kg (30-min) and 7.7 mmol/kg (24-h) estimated from narcosis theory. Keeping in mind the different end points (bioluminescence vs growth) involved, this finding demonstrates that chronic toxicity is not always more sensitive than acute toxicity, calling for analyses with regard to further respective

    Cannabinoid CB1 receptor antagonists have potential therapeutic benefits, but antagonist-elicited cannabis withdrawal has not been reported in humans. Ten male daily cannabis smokers received 8 days of increasingly frequent 20-mg oral Δ9-tetrahydrocannabinol (THC) dosages (40–120 mg/d) around-the-clock to standardize cannabis dependence while residing on a closed research unit. On the ninth day, double-blind placebo or 20- (suggested therapeutic dose) or 40-mg oral rimonabant, a CB1-cannabinoid receptor antagonist, was administered. Cannabis withdrawal signs and symptoms were assessed before and for 23.5 hours after rimonabant. Rimonabant, THC, and 11-hydroxy-THC plasma concentrations were quantified by mass spectrometry. The first 6 subjects received 20-mg rimonabant (1 placebo); the remaining 4 subjects received 40-mg rimonabant (1 placebo). Fourteen subjects enrolled; 10 completed before premature termination because of withdrawal of rimonabant from clinical development. Three of 5 subjects in the 20-mg group, 1 of 3 in the 40-mg group, and none of 2 in the placebo group met the prespecified withdrawal criterion of 150% increase or higher in at least 3 visual analog scales for cannabis withdrawal symptoms within 3 hours of rimonabant dosing. There were no significant associations between visual analog scale, heart rate, or blood pressure changes and peak rimonabant plasma concentration, area-under-the-rimonabant-concentration-by-time curve (0–8 hours), or peak rimonabant/THC or rimonabant/(THC + 11-hydroxy-THC) plasma concentration ratios. In summary, prespecified criteria for antagonist-elicited cannabis withdrawal were not observed at the 20- or 40-mg rimonabant doses. These data do not preclude antagonist-elicited withdrawal at higher rimonabant doses. PMID:21869692

  16. Antagonistic and synergistic interactions among predators.

    The structure and dynamics of food webs are largely dependent upon interactions among consumers and their resources. However, interspecific interactions such as intraguild predation and interference competition can also play a significant role in the stability of communities. The role of antagonistic/synergistic interactions among predators has been largely ignored in food web theory. These mechanisms influence predation rates, which is one of the key factors regulating food web structure and dynamics, thus ignoring them can potentially limit understanding of food webs. Using nonlinear models, it is shown that critical aspects of multiple predator food web dynamics are antagonistic/synergistic interactions among predators. The influence of antagonistic/synergistic interactions on coexistence of predators depended largely upon the parameter set used and the degree of feeding niche differentiation. In all cases when there was no effect of antagonism or synergism (a ( ij )=1.00), the predators coexisted. Using the stable parameter set, coexistence occurred across the range of antagonism/synergism used. However, using the chaotic parameter strong antagonism resulted in the extinction of one or both species, while strong synergism tended to coexistence. Whereas using the limit cycle parameter set, coexistence was strongly dependent on the degree of feeding niche overlap. Additionally increasing the degree of feeding specialization of the predators on the two prey species increased the amount of parameter space in which coexistence of the two predators occurred. Bifurcation analyses supported the general pattern of increased stability when the predator interaction was synergistic and decreased stability when it was antagonistic. Thus, synergistic interactions should be more common than antagonistic interactions in ecological systems.

Three of 5 subjects in the 20-mg group, 1 of 3 in the 40-mg group, and none of 2 in the placebo group met the prespecified withdrawal criterion of 150% increase or higher in at least 3 visual analog scales for cannabis withdrawal symptoms within 3 hours of rimonabant dosing. There were no significant associations between visual analog scale, heart rate, or blood pressure changes and peak rimonabant plasma concentration, area-under-the-rimonabant-concentration-by-time curve (0-8 hours), or peak rimonabant/THC or rimonabant/(THC + 11-hydroxy-THC) plasma concentration ratios. In summary, prespecified criteria for antagonist-elicited cannabis withdrawal were not observed at the 20- or 40-mg rimonabant doses. These data do not preclude antagonist-elicited withdrawal at higher rimonabant doses.

    Corticotropin-releasing factor (CRF) receptor antagonists have been sought since the stress-secreted peptide was isolated in 1981. Although evidence suggests the limited efficacy of CRF1 antagonists as antidepressants, CRF1 antagonists might be novel pharmacotherapies for anxiety and addiction. Progress in understanding the two-domain model of ligand–receptor interactions for CRF family receptors might yield chemically novel CRF1 receptor antagonists, including peptide CRF1 antagonists, antagonists with signal transduction selectivity and nonpeptide CRF1 antagonists that act via the extracellular (rather than transmembrane) domains. Novel ligands that conform to prevalent pharmacophore and exhibit drug-like pharmacokinetic properties have been identified. The therapeutic utility of CRF1 antagonists should soon be clearer: several small molecules are currently in Phase II/III clinical trials for depression, anxiety and irritable bowel syndrome.

    2011-01-01

    The Russian Federation (RF) is committed to implementing a comprehensive drug testing program under its Personnel Reliability Program (PRP) for military personnel involved in handling sensitive nuclear materials. This commitment leads to a number of mandatory requirements for the laboratory conducting the confirmation testing to ensure the legitimacy and integrity of the testing process. These requirements are established by the RF Duma to ensure that individuals conducting these tests have adequate training, certifications, and experience to conduct narcotic confirmation tests. This paper describes the facility requirements and personnel qualifications needed for conducting comprehensive drug abuse confirmation testing. Details regarding the personnel training and laboratory experience in the theory and practice of analytical forensic toxicology of drugs of abuse will be presented, as well as the facility requirements for the laboratory conducting such tests. Chain-of-custody, from sample receipt through completion of testing, reporting of results, and continuing until final disposition of specimens will be addressed.

    Opioids are widely used for the treatment of malignant and non-malignant pains. These medications are accompanied by adverse effects, in particular gastrointestinal symptoms known as opioid bowel dysfunction (OBD). The most common symptom of OBD is refractory constipation that is usually stable regardless of the use of laxatives. Narcotic bowel syndrome (NBS) is a subset of OBD described as ambiguous chronic pain aggravated by continual or increased opioid use for pain relief. Pathophysiology of these disorders are not definitely disentangled. Some challenging hypothesis have been posed leading to specific management in order to mitigate the adverse effects. This article is a review of the literature on the prevalence, pathophysiology and management of OBD and NBS.

    Narcosis is a neurological syndrome that reduces capacities of divers. Although this phenomenon appeared at the end of 19th century, the mechanisms are not yet elucidated. The greatest technical problem is that these studies are carried out under hyperbaric conditions. Nitrous oxide is known to be an inducer of narcosis, at atmospheric pressure. The aim of this study is to compare two narcotic environments; a normobaric narcosis under several percentages of nitrous oxide, and an hyperbaric narcosis under 0.9 MPa of Nitrox (N2O2 mixture). This comparison is realized on rats submitted to a fixed-ratio 15 test, in which they have to press a lever to get rewarded. The results show significant performances decreases: the number of pressed lever are reduced by 50% under Nitrox and by 70% under N2O. Nitrous oxide could be considered as a normobaric model of hyperbaric narcosis.

The method was evaluated in terms of the following characteristics: specificity, linearity, correctness, precision (reproducibility), and intra-laboratory precision. The proposed method can be applied for the quantitative evaluation of indomethacin, ketoprofen, and naproxen content as well as for the preliminary quantitative determination of ibuprofen and diclofenac in the framework of the chemico-toxicological and forensic chemical analysis. The method can be employed for the quantitative determination of ketorolac from such characteristics as «linearity» and «reproducibility».

    Objective: Substance abuse is a socio-psychological disorder. The aim of this study was to compare the effectiveness of acceptance and commitment therapy with 12-steps Narcotics Anonymous on psychological well-being of opiate dependent individuals in addiction treatment centers in Shiraz, Iran. Method: This was a randomized controlled trial. Data were collected at entry into the study and at post-test and follow-up visits. The participants were selected from opiate addicted individuals who referred to addiction treatment centers in Shiraz. Sixty individuals were evaluated according to inclusion/ exclusion criteria and were divided into three equal groups randomly (20 participants per group). One group received acceptance and commitment group therapy (Twelve 90-minute sessions) and the other group was provided with the 12-steps Narcotics Anonymous program and the control group received the usual methadone maintenance treatment. During the treatment process, seven participants dropped out. Data were collected using the psychological well-being questionnaire and AAQ questionnaire in the three groups at pre-test, post-test and follow-up visits. Data were analyzed using repeated measure analysis of variance. Results: Repeated measure analysis of variance revealed that the mean difference between the three groups was significant (P<0.05) and that acceptance and commitment therapy group showed improvement relative to the NA and control groups on psychological well-being and psychological flexibility. Conclusion: The results of this study revealed that acceptance and commitment therapy can be helpful in enhancing positive emotions and increasing psychological well-being of addicts who seek treatment.

    This study evaluated the toxic effects of substituted anilines on Pseudokirchneriella subcapitata with the use of a closed algal toxicity testing technique with no headspace. Two response endpoints (i.e., dissolved oxygen production [DO] and algal growth rate) were used to evaluate the toxicity of anilines. Both DO and growth rate endpoints revealed similar sensitivity to the effects of anilines. However, trichloroanilines showed stronger inhibitory effects on microalgal photosynthetic reactions than that on algal growth. For various aquatic organisms, the relative sensitivity relationship for anilines is Daphnia magna > luminescent bacteria (Microtox) > or = Pocelia reticulata > or = Pseudokirchneriella subcapitata > or = fathead minnow > Tetrahymena pyriformis. The susceptibility of P. subcapitata to anilines is similar to fish, but P. subcapitata is apparently less sensitive than the water flea. The lack of correlation between the toxicity revealed by different aquatic organisms (microalgae, D. magna, luminescent bacteria, and P. reticulata) suggests that anilines might have different metabolic routes in these organisms. Both hydrogen bonding donor capacity (the lowest unoccupied molecular orbital energy, Elumo) and hydrophobicity (1-octanol:water partition coefficient, Kow) were found to provide satisfactory descriptions for the toxicity of polar narcotics (substituted anilines and chlorophenols). Quantitative structure-activity relationships (QSARs) based on Elumo, log Kow, or both values were established with r2 values varying from 0.75 to 0.92. The predictive power for the QSAR models were found to be satisfactory through leave-one-out cross-validation. Such relationships could provide useful information for the estimation of toxicity for other polar narcotic compounds.

    Passive, standoff detection of chemical, explosive and narcotic threats employing widefield, shortwave infrared (SWIR) hyperspectral imaging (HSI) continues to gain acceptance in defense and security fields. A robust and user-friendly portable platform with such capabilities increases the effectiveness of locating and identifying threats while reducing risks to personnel. In 2013 ChemImage Sensor Systems (CISS) introduced Aperio, a handheld sensor, using real-time SWIR HSI for wide area surveillance and standoff detection of explosives, chemical threats, and narcotics. That SWIR HSI system employed a liquid-crystal tunable filter for real-time automated detection and display of threats. In these proceedings, we report on a next generation device called VeroVision™, which incorporates an improved optical design that enhances detection performance at greater standoff distances with increased sensitivity and detection speed. A tripod mounted sensor head unit (SHU) with an optional motorized pan-tilt unit (PTU) is available for precision pointing and sensor stabilization. This option supports longer standoff range applications which are often seen at checkpoint vehicle inspection where speed and precision is necessary. Basic software has been extended to include advanced algorithms providing multi-target display functionality, automatic threshold determination, and an automated detection recipe capability for expanding the library as new threats emerge. In these proceedings, we report on the improvements associated with the next generation portable widefield SWIR HSI sensor, VeroVision™. Test data collected during development are presented in this report which supports the targeted applications for use of VeroVision™ for screening residue and bulk levels of explosive and drugs on vehicles and personnel at checkpoints as well as various applications for other secure areas. Additionally, we highlight a forensic application of the technology for assisting forensic

    2013-01-01

    Kappa opioid receptors (KORs) belong to the G-protein coupled class of receptors (GPCRs). They are activated by the endogenous opioid peptide dynorphin (DYN) and expressed at particularly high levels within brain areas implicated in modulation of motivation, emotion, and cognitive function. Chronic activation of KORs in animal models has maladaptive effects including increases in behaviors that reflect depression, the propensity to engage in drug-seeking behavior, and drug craving. The fact that KOR activation has such a profound influence on behaviors often triggered by stress has led to interest in selective KOR antagonists as potential therapeutic agents. This perspective provides a description of preclinical research conducted in the development of several different classes of selective KOR antagonists, a summary of the clinical studies conducted thus far, and recommendations for the type of work needed in the future to determine if these agents would be useful as pharmacotherapies for neuropsychiatric illness.

  9. The treatment of hyponatraemia using vasopressin antagonists.

    PubMed

    2000-03-01

    Hyponatraemia is a frequent electrolyte disorder. It is primarily attributable to vasopressin excess plus sustained fluid intake. Hyponatraemia causes CNS symptoms, especially during the first 2-4 days; these symptoms are related to brain swelling. Hyponatraemia occurs in the setting of liver cirrhosis and congestive cardiac failure, in which it is related to stimulation by low arterial blood pressure acting through baroreceptors. Hyponatraemia also occurs in the syndrome of inappropriate antidiuretic hormone secretion, usually from neoplasms releasing vasopressin. The conventional treatment of hyponatraemia used to be fluid restriction and treatment of the underlying disorder. This kind of treatment has been unreliable, cumbersome and difficult to comply with for the patient. In the future, effective vasopressin V2 antagonists will become available for clinical use in the treatment of hyponatraemia, and are expected to improve the management of hyponatraemia. Pharmacological characteristics and observations of biological effects of three antagonists are reported in the present article.

    Cough is an important defensive pulmonary reflex that removes irritants, fluids, or foreign materials from the airways. However, when cough is exceptionally intense or when it is chronic and/or nonproductive it may require pharmacologic suppression. For many patients, antitussive therapies consist of OTC products with inconsequential efficacies. On the other hand, the prescription antitussive market is dominated by older opioid drugs such as codeine. Unfortunately, "codeine-like" drugs suppress cough at equivalent doses that also often produce significant ancillary liabilities such as GI constipation, sedation, and respiratory depression. Thus, the discovery of a novel and effective antitussive drug with an improved side effect profile relative to codeine would fulfill an unmet clinical need in the treatment of cough. Afferent pulmonary nerves are endowed with a multitude of potential receptor targets, including TRPV1, that could act to attenuate cough. The evidence linking TRPV1 to cough is convincing. TRPV1 receptors are found on sensory respiratory nerves that are important in the generation of the cough reflex. Isolated pulmonary vagal afferent nerves are responsive to TRPV1 stimulation. In vivo, TRPV1 agonists such as capsaicin elicit cough when aerosolized and delivered to the lungs. Pertinent to the debate on the potential use of TRPV1 antagonist as antitussive agents are the observations that airway afferent nerves become hypersensitive in diseased and inflamed lungs. For example, the sensitivity of capsaicin-induced cough responses following upper respiratory tract infection and in airway inflammatory diseases such as asthma and COPD is increased relative to that of control responses. Indeed, we have demonstrated that TRPV1 antagonism can attenuate antigen-induced cough in the allergic guinea pig. However, it remains to be determined if the emerging pharmacologic profile of TRPV1 antagonists will translate into a novel human antitussive drug. Current

    ABSTRACT Cyanobacterial and algal mass development, or blooms, have severe effects on freshwater and marine systems around the world. Many of these phototrophs produce a variety of potent toxins, contribute to oxygen depletion, and affect water quality in several ways. Coexisting antagonists, such as cyanolytic bacteria, hold the potential to suppress, or even terminate, such blooms, yet the nature of this interaction is not well studied. We isolated 31 cyanolytic bacteria affiliated with the genera Pseudomonas, Stenotrophomonas, Acinetobacter, and Delftia from three eutrophic freshwater lakes in Sweden and selected four phylogenetically diverse bacterial strains with strong-to-moderate lytic activity. To characterize their functional responses to the presence of cyanobacteria, we performed RNA sequencing (RNA-Seq) experiments on coculture incubations, with an initial predator-prey ratio of 1:1. Genes involved in central cellular pathways, stress-related heat or cold shock proteins, and antitoxin genes were highly expressed in both heterotrophs and cyanobacteria. Heterotrophs in coculture expressed genes involved in cell motility, signal transduction, and putative lytic activity. l,d-Transpeptidase was the only significantly upregulated lytic gene in Stenotrophomonas rhizophila EK20. Heterotrophs also shifted their central metabolism from the tricarboxylic acid cycle to the glyoxylate shunt. Concurrently, cyanobacteria clearly show contrasting antagonistic interactions with the four tested heterotrophic strains, which is also reflected in the physical attachment to their cells. In conclusion, antagonistic interactions with cyanobacteria were initiated within 24 h, and expression profiles suggest varied responses for the different cyanobacteria and studied cyanolytes. IMPORTANCE Here, we present how gene expression profiles can be used to reveal interactions between bloom-forming freshwater cyanobacteria and antagonistic heterotrophic bacteria. Species

    Kainic acid (KA) receptors belong to the group of ionotropic glutamate receptors and are expressed throughout in the central nervous system (CNS). The KA receptors have been shown to be involved in neurophysiological functions such as mossy fiber long-term potentiation (LTP) and synaptic plasticity and are thus potential therapeutic targets in CNS diseases such as schizophrenia, major depression, neuropathic pain and epilepsy. Extensive effort has been made to develop subtype-selective KA receptor antagonists in order to elucidate the physiological function of each of the five subunits known (GluK1-5). However, to date only selective antagonists for the GluK1 subunit have been discovered, which underlines the strong need for continued research in this area. The present review describes the structure-activity relationship and pharmacological profile for 10 chemically distinct classes of KA receptor antagonists comprising, in all, 45 compounds. To the medicinal chemist this information will serve as reference guidance as well as an inspiration for future effort in this field.

    Depression is a psychiatric disorder that affects millions of people worldwide. Individuals battling this disorder commonly experience high rates of relapse, persistent residual symptoms, functional impairment, and diminished well-being. Medications have important utility in stabilizing moods and daily functions of many individuals. However, only one third of patients had considerable improvement with a standard antidepressant after 2 months and all patients had to deal with numerous side effects. The N-methyl-d-aspartate (NMDA) receptor family has received special attention because of its critical role in psychiatric disorders. Direct targeting of the NMDA receptor could result in more rapid antidepressant effects. Antidepressant-like effects of NMDA receptor antagonists have been demonstrated in different animal models. MK-801 (a use-dependent channel blocker), and CGP 37849 (an NMDA receptor antagonist) have shown antidepressant properties in preclinical studies, either alone or combined with traditional antidepressants. A recent development is use of ketamine clinically for refractory depression. The purpose of this review is to examine and analyze current literature on the role of NMDA receptor antagonists for treatment of depression and whether this is a feasible route in drug discovery.

    This work focuses on two aspects of the action of calcium antagonist drugs, namely, the interaction of drugs with receptors for verapamil-like calcium antagonists, and the interactions of drugs with voltage-sensitive calcium fluxes in rat brain synaptosomes. From binding studies I have found that the ligand of choice for labeling the verapamil receptor is (-)(/sup 3/H)desmethoxy-verapamil. This drug labels potently, reversibly and stereoselectively two receptors in membranes prepared from rat brain and rabbit skeletal muscle tissues. In equilibrium studies dihydropyridine calcium antagonists interact in a non-competitive fashion, while many non-DHPs are apparently competitive. In-depth kinetic studies in skeletal muscle membranes indicate that the two receptors are linked in a negative heterotropic fashion, and that low-affinity binding of (-) (/sup 3/H)desmethoxy-verapamil may be to the diltiazem receptor. However, these studies were not able to distinguish between the hypothesis that diltiazem binds to spatially separate, allosterically coupled receptors, and the hypothesis that diltiazem binds to a subsite of the verapamil receptor.

    Neuronal progenitors and tumor cells possess propensity to proliferate and to migrate. Glutamate regulates proliferation and migration of neurons during development, but it is not known whether it influences proliferation and migration of tumor cells. We demonstrate that glutamate antagonists inhibit proliferation of human tumor cells. Colon adenocarcinoma, astrocytoma, and breast and lung carcinoma cells were most sensitive to the antiproliferative effect of the N-methyl-D-aspartate antagonist dizocilpine, whereas breast and lung carcinoma, colon adenocarcinoma, and neuroblastoma cells responded most favorably to the -amino-3-hydroxy-5-methyl-4-isoxazole-propionate antagonist GYKI52466. The antiproliferative effect of glutamate antagonists was Ca2+ dependent and resulted from decreased cell division and increased cell death. Morphological alterations induced by glutamate antagonists in tumor cells consisted of reduced membrane ruffling and pseudopodial protrusions. Furthermore, glutamate antagonists decreased motility and invasive growth of tumor cells. These findings suggest anticancer potential of glutamate antagonists.

After the organic polymer-based monolithic column was prepared by an in-situ polymerization procedure, a systematic investigation of the pressure-assisted CEC separation and ESI-MS detection parameters was performed. Baseline separation of the studied analytes could be obtained using the solution containing 75% ACN v/v and 20 mmol/L ammonium acetate with pH 8.0 as running buffer, when applying separation voltage of 20 kV and assisted pressure of 5 bar. Under the optimized conditions, two beta(2)-agonists and three narcotics could be completely resolved and accurately determined within 15 min. Finally, the proposed method was successfully used for real urine samples detection.

    Effective atomic numbers for photon energy absorption ZPEA,eff, photon interaction ZPI,eff and for electron density Nel, have been calculated by a direct method in the photon-energy region from 1 keV to 20 MeV for narcotic drugs, such as Heroin (H), Cocaine (CO), Caffeine (CA), Tetrahydrocannabinol (THC), Cannabinol (CBD), Tetrahydrocannabivarin (THCV). The ZPEA,eff, ZPI,eff and Nel values have been found to change with energy and composition of the narcotic drugs. The energy dependence ZPEA,eff, ZPI,eff and Nel is shown graphically. The maximum difference between the values of ZPEA,eff, and ZPI,eff occurs at 30 keV and the significant difference of 2 to 33% for the energy region 5-100 keV for all drugs. The reason for these differences is discussed.

    In an ongoing effort to explore the use of orexin receptor antagonists for the treatment of insomnia, dual orexin receptor antagonists (DORAs) were structurally modified, resulting in compounds selective for the OX2R subtype and culminating in the discovery of 23, a highly potent, OX2R-selective molecule that exhibited a promising in vivo profile. Further structural modification led to an unexpected restoration of OX1R antagonism. Herein, these changes are discussed and a rationale for selectivity based on computational modeling is proposed.

    A pressure-assisted CEC (pCEC) with ESI-MS based on silica-based monolithic column was developed for rapid analysis of narcotics. Combining the extremely high permeability and separation efficiency of silica-based monolithic column with the high selectivity and sensitivity of pCEC-ESI-MS, the developed system exhibited its prominent advantages in separation and detection. A systematic investigation of the pCEC separation and ESI-MS detection parameters was performed. Experiment results showed that the optimized separation efficiency could be obtained at 8 bar assisted pressure with 25 kV separation voltage, using the solution containing 65% ACN v/v and 20 mmol/L ammonium acetate with pH 6.0 as running buffer. 3 microL/min of sheath liquid was considered as the optimized flow rate since it could provide the maximum signal intensity. Under the optimum conditions, the tested five narcotics could be completely separated within 10 min with the detection limit in the range of 2.0-80 nmol/L. The proposed method has been successfully used for detection of narcotics in real urine samples.

    Narcotic analgesics are widely (ab) used and sometimes only occur in low concentrations in biological samples. Therefore, a highly sensitive liquid chromatography tandem mass spectrometry method was developed for simultaneous analysis of 9 narcotic analgesics and metabolites (buprenorphine, O-desmethyltramadol, fentanyl, norbuprenorphine, norfentanyl, pethidine, piritramide, tilidine and tramadol) in urine and whole blood. Sample preparation was performed on a mixed-mode cation exchange solid phase extraction cartridge with an additional alkaline wash step to decrease matrix effects and thus increase sensitivity. Ionization with electrospray ionization was found to be more efficient than atmospheric pressure chemical ionization. The use of a mobile phase of high pH resulted in higher electrospray ionization signals than the conventional low pH mobile phases. In the final method, gradient elution with 10mM ammonium bicarbonate (pH 9) and methanol was performed on a small particle column (Acquity C18, 1.7 μm, 2.1 mm × 50 mm). Selectivity, matrix effects, recovery, linearity, sensitivity, precision, accuracy and stability were validated in urine and whole blood. All parameters were successfully evaluated and the method showed very high sensitivity, which was the major aim of this study. The applicability of the method was demonstrated by analysis of several forensic cases involving narcotic analgesics.

    In this paper a set of homogenous experimental algal toxicity data was measured for 50 non-polar narcotic chemicals using the alga Pseudokirchneriella subcapitata in a closed test with a growth rate endpoint. Most of the tested compounds are high volume industrial chemicals that so far lacked published REACH-compliant algal growth inhibition values. The test protocol fulfilled the criteria set forth in the OECD guideline 201 and had the same sensitivity as the open test which allowed direct comparison of toxicity values. Baseline QSAR model for non-polar narcotic compounds was established and compared with previous analogous models. Multi-linear QSAR model was derived for the non-polar and 58 previously tested polar (anilines and phenols) narcotic compounds modulating hydrophobicity, molecular size, electronic and molecular stability effects coded in the molecular descriptors. Descriptors in the model were analyzed and applicability domain was assessed providing further guidelines for the in silico prediction purposes in decision support while performing risk assessment. QSAR models in the manuscript are available on-line through QsarDB repository for exploring and prediction services (http://hdl.handle.net/10967/106).

  4. Antagonistic functional duality of cancer genes.

    Cancer evolution is a stochastic process both at the genome and gene levels. Most of tumors contain multiple genetic subclones, evolving in either succession or in parallel, either in a linear or branching manner, with heterogeneous genome and gene alterations, extensively rewired signaling networks, and addicted to multiple oncogenes easily switching with each other during cancer progression and medical intervention. Hundreds of discovered cancer genes are classified according to whether they function in a dominant (oncogenes) or recessive (tumor suppressor genes) manner in a cancer cell. However, there are many cancer "gene-chameleons", which behave distinctly in opposite way in the different experimental settings showing antagonistic duality. In contrast to the widely accepted view that mutant NADP(+)-dependent isocitrate dehydrogenases 1/2 (IDH1/2) and associated metabolite 2-hydroxyglutarate (R)-enantiomer are intrinsically "the drivers" of tumourigenesis, mutant IDH1/2 inhibited, promoted or had no effect on cell proliferation, growth and tumorigenicity in diverse experiments. Similar behavior was evidenced for dozens of cancer genes. Gene function is dependent on genetic network, which is defined by the genome context. The overall changes in karyotype can result in alterations of the role and function of the same genes and pathways. The diverse cell lines and tumor samples have been used in experiments for proving gene tumor promoting/suppressive activity. They all display heterogeneous individual karyotypes and disturbed signaling networks. Consequently, the effect and function of gene under investigation can be opposite and versatile in cells with different genomes that may explain antagonistic duality of cancer genes and the cell type- or the cellular genetic/context-dependent response to the same protein. Antagonistic duality of cancer genes might contribute to failure of chemotherapy. Instructive examples of unexpected activity of cancer genes and

    The purpose was to assess a novel form of strength training, antagonist resisted training (ART), with potential use in microgravity and athletic rehabilitation settings. ART uses the force from antagonist muscles, during cocontractions, as the source of resistance for the agonists. Strength and electromyography (EMG) measurements were recorded before and after a 6-week training program during which participants trained the left arm while the right arm served as a control. Training was designed so that the elbow extensors (antagonists) served as resistance for the elbow flexors (agonists). Elbow flexor and extensor strengths were measured during maximal isometric contractions with the elbow fixed at 90 degrees. EMG was recorded from the biceps brachii and lateral head of the triceps brachii during all strength tests. EMG was also recorded from both muscles during a maximal isometric cocontraction of the elbow flexors and extensors. Elbow flexion strength increased significantly for the trained arm (5.8%) relative to the control (0.5%) (p = 0.003). Elbow extension strength of the trained limb also increased significantly (8.5%) relative to the control (4.5%) (p = 0.029). Biceps and triceps EMG, during maximum strength tests, increased significantly for the trained arm (18.5 and 18.6%) relative to the control (0.5 and -5.2%) (p = 0.035 and p = 0.01). Biceps and triceps EMG, during maximum cocontraction tests, increased significantly for the trained arm (30.1 and 61.1%) relative to the control (9.2 and 1.1%) (p = 0.042 and p = 0.0005). ART was found to increase strength and therefore could be an effective form of resistance training. Because it requires no equipment, ART may be especially applicable in microgravity environments, which have space and weight constraints.

    Hyperaldosteronism has been associated with endothelial dysfunction and impaired vascular reactivity in patients with hypertension or congestive heart failure. The mineralocorticoid receptor (MR) antagonists spironolactone and eplerenone have been shown to reduce morbidity and mortality, in part, by ameliorating the adverse effects of aldosterone on vascular function. Although spironolactone and eplerenone are increasingly utilized in patients with cardiovascular disease, widespread clinical use is limited by the development of gynecomastia with spironolactone and hyperkalemia with both agents. This suggests that the development of newer agents with favorable side effect profiles is warranted. PMID:18729003

    The pregnane X receptor belongs to the nuclear hormone receptor superfamily and is involved in the transcriptional control of numerous genes. It was originally thought that it was a xenobiotic sensor controlling detoxification pathways. Recent studies have shown an increasingly important role in inflammation and cancer, supporting its function in abrogating tissue damage. PXR orthologs and PXR-like pathways have been identified in several non-mammalian species which corroborate a conserved role for PXR in cellular detoxification. In summary, PXR has a multiplicity of roles in vivo and is being revealed as behaving like a “Jekyll and Hyde” nuclear hormone receptor. The importance of this review is to elucidate the need for discovery of antagonists of PXR to further probe its biology and therapeutic applications. Although several PXR agonists are already reported, virtually nothing is known about PXR antagonists. Here, we propose the development of PXR antagonists through chemical, genetic and molecular modeling approaches. Based on this review it will be clear that antagonists of PXR and PXR-like pathways will have widespread utility in PXR biology and therapeutics. PMID:19415465

    Nuclear hormone receptors (NRs) are potential targets for therapeutic approaches to many clinical conditions, including cancer, diabetes, and neurological diseases. The crystal structure of the ligand binding domain of agonist-bound NRs enables the design of compounds with agonist activity. However, with the exception of the human estrogen receptor-, the lack of antagonist-bound "inactive" receptor structures hinders the rational design of receptor antagonists. In this study, we present a strategy for designing such antagonists. We constructed a model of the inactive conformation of human retinoic acid receptor- by using information derived from antagonist-bound estrogen receptor-α and applied a computer-based virtual screening algorithm to identify retinoic acid receptor antagonists. Thus, the currently available crystal structures of NRs may be used for the rational design of antagonists, which could lead to the development of novel drugs for a variety of diseases.

    We studied the antioxidant activities of calcium antagonists against autoxidation in rat brain homogenates. The homogenates were incubated for 30 min at 37 degrees C with or without a calcium antagonist and subsequently assayed for lipid peroxide content. Percent inhibition of the lipid peroxidation was used as an index of the antioxidant effect. Dihydropyridine calcium antagonists exhibited concentration-dependent (3-300 micromol/l) inhibitory effects against lipid peroxidation. The relative order of antioxidant potency and associated IC50 values (micromol/l) of the calcium antagonists for inhibition of the lipid peroxidation were as follows: nifedipine (51.5)>barnidipine (58.6)>benidipine (71.2)>nicardipine (129.3)>amlodipine (135.5)>nilvadipine (167.3)>nitrendipine (252.1)> diltiazem (>300)=verapamil (>300). These results suggest that some dihydropyridine calcium antagonists show antioxidant properties. The antioxidant effects of the calcium antagonists may contribute to their pharmacological actions.

    This study evaluates the effects of the IP injection of naloxone (0.3, 3 and 30 mg/kg) and naltrexone (0.2, 2 and 20 mg/kg) on the sexual satiation phenomenon. It was found that both antagonists exert a dose-based biphasic effect on the proportion of sexually exhausted rats displaying copulation. The intermediate doses of both opioid antagonists were more effective than the low and high doses in increasing the percentage of animals engaged in copulation. The analysis of the specific sexual behaviour parameters revealed that naloxone produces a slight inhibitory effect at the lowest dose, evidenced as an increase in the intromission number. The higher doses of this compound facilitated copulation reflected as a shortening of the ejaculation latency and the interintromission interval (III) and an increase in the copulatory rate. Naltrexone treatment had only facilitatory effects at the lower doses by reducing the III. The higher doses of naloxone (3 and 30 mg/kg) and the intermediate dose of naltrexone (2 mg/kg) decreased the spontaneous ambulatory behaviour of sexually satiated rats without impairing sexual behaviour execution. Data suggest a participation of the endogenous opioid systems in the sexual inhibition resulting from sexual exhaustion.

    PubMed

    Lanthorn, T H

    1994-10-01

    D-Cycloserine can enhance activation of the NMDA receptor complex and could enhance the induction of long-term potentiation (LTP). In animals and humans, D-cycloserine can enhance performance in learning and memory tasks. This enhancing effect can disappear during repeated administration. The enhancing effects are also lost when higher doses are used, and replaced by behavioral and biochemical effects like those produced by NMDA antagonists. It has been reported that NMDA agonists, applied before or after tetanic stimulation, can block the induction of LTP. This may be the result of feedback inhibition of second messenger pathways stimulated by receptor activation. This may explain the antagonist-like effects of glycine partial agonists like D-cycloserine. In clinical trials of D-cycloserine in age-associated memory impairment (AAMI) and Alzheimer's disease, chronic treatment provided few positive effects on learning and memory. This may be due to inhibition of second messenger pathways following chronic stimulation of the receptor complex.

    Zebrafish represents a powerful in vivo model for phenotype-based drug discovery to identify clinically relevant small molecules. By utilizing this model, we evaluated natural product derived compounds that could potentially modulate Notch signaling that is important in both zebrafish embryogenesis and pathogenic in human cancers. A total of 234 compounds were screened using zebrafish embryos and 3 were identified to be conferring phenotypic alterations similar to embryos treated with known Notch inhibitors. Subsequent secondary screens using HEK293T cells overexpressing truncated Notch1 (HEK293TΔE) identified 2 compounds, EDD3 and 3H4MB, to be potential Notch antagonists. Both compounds reduced protein expression of NOTCH1, Notch intracellular domain (NICD) and hairy and enhancer of split-1 (HES1) in HEK293TΔE and downregulated Notch target genes. Importantly, EDD3 treatment of human oral cancer cell lines demonstrated reduction of Notch target proteins and genes. EDD3 also inhibited proliferation and induced G0/G1 cell cycle arrest of ORL-150 cells through inducing p27(KIP1). Our data demonstrates the utility of the zebrafish phenotypic screen and identifying EDD3 as a promising Notch antagonist for further development as a novel therapeutic agent.

    Several lines of evidence indicate the existence of genetic factors influencing male homosexuality and bisexuality. In spite of its relatively low frequency, the stable permanence in all human populations of this apparently detrimental trait constitutes a puzzling 'Darwinian paradox'. Furthermore, several studies have pointed out relevant asymmetries in the distribution of both male homosexuality and of female fecundity in the parental lines of homosexual vs. heterosexual males. A number of hypotheses have attempted to give an evolutionary explanation for the long-standing persistence of this trait, and for its asymmetric distribution in family lines; however a satisfactory understanding of the population genetics of male homosexuality is lacking at present. We perform a systematic mathematical analysis of the propagation and equilibrium of the putative genetic factors for male homosexuality in the population, based on the selection equation for one or two diallelic loci and Bayesian statistics for pedigree investigation. We show that only the two-locus genetic model with at least one locus on the X chromosome, and in which gene expression is sexually antagonistic (increasing female fitness but decreasing male fitness), accounts for all known empirical data. Our results help clarify the basic evolutionary dynamics of male homosexuality, establishing this as a clearly ascertained sexually antagonistic human trait.

    2011-01-01

    Hypocretin neuropeptides have been shown to regulate transitions between wakefulness and sleep through stabilization of sleep promoting GABAergic and wake promoting cholinergic/monoaminergic neural pathways. Hypocretin also influences other physiologic processes such as metabolism, appetite, learning and memory, reward and addiction, and ventilatory drive. The discovery of hypocretin and its effect upon the sleep-wake cycle has led to the development of a new class of pharmacologic agents that antagonize the physiologic effects of hypocretin (i.e. hypocretin antagonists). Further investigation of these agents may lead to novel therapies for insomnia without the side-effect profile of currently available hypnotics (e.g. impaired cognition, confusional arousals, and motor balance difficulties). However, antagonizing a system that regulates the sleep-wake cycle while also influencing non-sleep physiologic processes may create an entirely different but equally concerning side-effect profile such as transient loss of muscle tone (i.e. cataplexy) and a dampened respiratory drive. In this review, we will discuss the discovery of hypocretin and its receptors, hypocretin and the sleep-wake cycle, hypocretin antagonists in the treatment of insomnia, and other implicated functions of the hypocretin system.

    A methodology for active spring generation is presented based on antagonistic redundant actuation. Antagonistic properties are characterized using an effective system stiffness. 'Antagonistic stiffness' is generated by preloading a closed-chain (parallel) linkage system. Internal load distribution is investigated along with the necessary conditions for spring synthesis. The performance and stability of a proposed active spring are shown by simulation, and applications are discussed.

    This work offers a real-world comparison of derivative preprocessing and a new polynomial method described by Lieber and Mahadevan-Jansen (LMJ) for baseline correction of Raman spectra with widely varying backgrounds. This comparison is based on their outcomes in factor analysis, analyte discrimination, and quantification. Both correction methods are applied to a Raman spectra data set taken from 85 solid samples of illegal narcotics diluted with various materials. It is found that neither approach outperforms the other, as they give similar principal component analysis (PCA) models and quantification errors: cocaine and heroin show cross-validation errors of approximately 8%, while MDMA is quantified to a cross-validation error of approximately 3-4%. The LMJ method does offer several other advantages, the most significant being the retention of original peak shapes after the correction, which simplifies the interpretation of the preprocessed spectra. The LMJ method is therefore recommended for use as a baseline correction method in future research with Raman spectroscopy.

    A fast method has been developed for the simultaneous determination of 52 stimulants and narcotics excreted unconjugated in urine by gas chromatography/mass spectrometry (GC/MS). The procedure involves the liquid/liquid extraction of the analytes from urine at strong alkaline pH and the injection of the extract into a GC/MS instrument with a fast GC column (10 m x 0.18 mm i.d.); the short column allows the complete separation of the 52 analytes in a chromatographic run of 8 min. The method has been fully validated giving lower limits of detection (LLODs) satisfactory for its application to antidoping analysis as well as to forensic toxicology. The repeatability of the concentrations and the retention times are good both for intra- and for inter-day experiments (%CV of concentrations always lower than 15 and %CV of retention times lower than 0.6). In addition, the analytical bias is satisfactory (A% always >15%). The method proposed here would be particularly useful whenever there are time constraints and the analyses have to be completed in the shortest possible time.

  19. Re-analysis of narcotic critical body residue data using the equilibrium distribution concept and refined partition coefficients.

    2016-08-10

    Narcosis occurs as a result of the accumulation of chemicals in the phospholipid membrane. The toxic threshold concentration in the membrane is thought to be relatively constant across different chemicals and species. Hence, estimating chemical concentrations in the membrane is expected to reduce the variability of narcotic critical body residue (CBR) data. In this study, a high quality CBR dataset for three aquatic species reported recently in the literature was evaluated with the internal equilibrium distribution concept. The raw wet-weight-based CBR values were converted to membrane-weight-based CBR values by assuming that the chemical is distributed in storage lipids, membranes, proteins, and water according to the respective equilibrium partition coefficients. Several sets of partition coefficients were compared for this analysis. The results were consistent with the notion that the use of a structural protein instead of serum albumin as a surrogate for the body protein fraction could reduce the variability of CBRs. Partition coefficients predicted by polyparameter linear free energy relationships (PP-LFERs) reduced the variability of CBRs as much as or even more than experimental partition coefficients did. It is suggested that CBR data for chemicals with larger structural diversity and biological species with more distinct compositions are needed to evaluate further the equilibrium distribution concept and the constant membrane threshold hypothesis.

    The development, manufacture, trade and distribution of medicines all take place within a web of international legal obligations that states have accepted under a range of multilateral, plurilateral and bilateral agreements. International law can operate either to facilitate or hinder access, depending on how it is developed and implemented. This article examines two areas of international law that are relevant to cancer treatment: the international drug control system, which regulates opioid analgesics; and the World Trade Organization's Trade-Related Aspects of Intellectual Property Agreement. This article outlines recent developments in relation to both, including in the activities of the Vienna-based agencies that collectively oversee the implementation of the Single Convention on Narcotic Drugs, and in the negotiation of the recent United Nations General Assembly Political Declaration on Non-communicable Diseases. While underlining the importance of law, this article notes that battles over law should not distract from the importance of other essential efforts to enhance access to medicines within the context of the strengthening of health systems.

  1. The sacred journey in dynastic Egypt: shamanistic trance in the context of the narcotic water lily and the mandrake.

    Contemporary reference to the role of water lilies and mandrakes (Nymphaea and Mandragora, respectively) in ancient Egyptian healing, and subsequent research on the iconography of the water lily in Mayan shamanistic ritual, suggest the possible importance of these plants as adjuncts to shamanistic healing in dynastic Egypt. Although the usual interpretation of the water lily and the mandrake has been that of a part of ritual mourning, the present article revises this notion. Based on an extensive review of these two powerful narcotic (i.e., hypnotic) plants in iconography and ritual, it is argued that the dynastic Egyptians had developed a form of shamanistic trance induced by these two plants and used it in medicine as well as healing rituals. Analysis of the ritual and sacred iconography of dynastic Egypt, as seen on stelae, in magical papyri, and on vessels, indicates that these people possessed a profound knowledge of plant lore and altered states of consciousness. The abundant data indicate that the shamanistic priest, who was highly placed in the stratified society, guided the souls of the living and dead, provided for the transmutation of souls into other bodies and the personification of plants as possessed by human spirits, as well as performing other shamanistic activities.

    Inhibitor of apoptosis (IAP) proteins play pivotal roles in cellular survival by blocking apoptosis, modulating signal transduction, and affecting cellular proliferation. Through their interactions with inducers and effectors of apoptosis IAP proteins can effectively suppress apoptosis triggered by diverse stimuli including death receptor signaling, irradiation, chemotherapeutic agents, or growth factor withdrawal. Evasion of apoptosis, in part due to the action of IAP proteins, enhances resistance of cancer cells to treatment with chemotherapeutic agents and contributes to tumor progression. Additionally, IAP genes are known to be subject to amplification, mutation, and chromosomal translocation in human malignancies and autoimmune diseases. In this review we will discuss the role of IAP proteins in cancer and the development of antagonists targeting IAP proteins for cancer treatment.

    We formulate the head-to-head matchups between Major League Baseball pitchers and batters from 1954 to 2008 as a bipartite network of mutually-antagonistic interactions. We consider both the full network and single-season networks, which exhibit structural changes over time. We find interesting structure in the networks and examine their sensitivity to baseball’s rule changes. We then study a biased random walk on the matchup networks as a simple and transparent way to (1) compare the performance of players who competed under different conditions and (2) include information about which particular players a given player has faced. We find that a player’s position in the network does not correlate with his placement in the random walker ranking. However, network position does have a substantial effect on the robustness of ranking placement to changes in head-to-head matchups.

    The research presented here has shown that tolerance to drugs can be accelerated by conditioning processes. Placebo effects may be considered the opposite of tolerance, and we have shown that placebo effects may be objectively recorded by physiological measures (electromyography, skin conductance responses, and event-related potentials), as well as by behavioral and subjective methods. The placebo response, or more precisely, the expectation of drug effects, can add to the effect of the drug. Drug antagonistic expectations can also reverse the effect of the drug. There is some evidence that placebo effects are strongest when expectations are reinforced by administration of an active drug. Expectations have graded effects and may affect symptoms to a smaller or larger degree. Although drug effects can be considered stimuli, the investigation of the role of classical conditioning in drug use and drug effects involves special issues that must be carefully considered.

    Desquand, S

    1993-01-01

    The discovery, during the last ten years, of Platelet Activating Factor (PAF) antagonists with different frameworks, but efficient on platelets tests, led the authors to study their activity in vivo against PAF-induced effects. These antagonists inhibit, with various potencies, the effects of PAF administration such as hypotension and bronchoconstriction in different animal species. Since PAF is assumed to play a central role in many diseases, effects of its antagonists have been studied in experimentally induced pathologies and in few clinical studies. We have been particularly interested in their effects on the first manifestation of asthma which is hypersensitivity. This manifestation is experimentally reproduced by anaphylactic bronchoconstriction, usually in the guinea-pig. Our results showed that different sensitization procedures may determine the relative efficiency of a PAF antagonist on subsequent antigen challenge. Indeed, the booster injection of antigen to a pre-sensitized animal could account for the refractoriness of anaphylactic bronchoconstriction to PAF antagonists. This booster injection mimics the clinical situation of atopic patients repeatedly exposed to allergen. Thus, it seems that immediate hypersensitivity could not be treated by the unique administration of a PAF antagonist. However, those antagonists may have more benefit in the clinical management of the late phase of asthma and of hyperreactivity and could thus provide anti-asthmatic drugs. PAF antagonists may have also therapeutical effects in septic shock, in myocardial ischemia and cardiac rhythm disturbances, in brain damage following cerebral ischemia and neurological trauma, in gastric and intestinal damages or in some inflammatory reactions.

    2015-01-01

    The first mineralocorticoid receptor (MR) antagonist, spironolactone, was developed almost 60 years ago to treat primary aldosteronism and pathological edema. Its use waned in part due to its lack of selectivity. Subsequently knowledge of the scope of MR function was expanded along with clinical evidence of the therapeutic importance of MR antagonists to prevent the ravages of inappropriate MR activation. Forty-two years elapsed between the first and MR-selective second generation of MR antagonists. Fifteen years later, despite serious shortcomings of the existing antagonists, a third generation antagonist has yet to be marketed. Progress has been slowed by the lack of appreciation of the large variety of cell types that express the MR and its diverse cell-type-specific actions, as well as its uniquely complex interactions actions at the molecular level. New MR antagonists should preferentially target the inflammatory and fibrotic effects of MR and perhaps its excitatory effects on sympathetic nervous system, but not the renal tubular epithelium or neurons of the cortex and hippocampus. This review briefly describes efforts to develop a third generation MR antagonist and why fourth generation antagonists and selective agonists based on structural determinants of tissue and ligand-specific MR activation should be contemplated.

    2009-01-01

    Identification of the primary products of cyclo-oxygenase (COX)/prostaglandin synthase(s), which occurred between 1958 and 1976, was followed by a classification system for prostanoid receptors (DP, EP1, EP2 …) based mainly on the pharmacological actions of natural and synthetic agonists and a few antagonists. The design of potent selective antagonists was rapid for certain prostanoid receptors (EP1, TP), slow for others (FP, IP) and has yet to be achieved in certain cases (EP2). While some antagonists are structurally related to the natural agonist, most recent compounds are ‘non-prostanoid’ (often acyl-sulphonamides) and have emerged from high-throughput screening of compound libraries, made possible by the development of (functional) assays involving single recombinant prostanoid receptors. Selective antagonists have been crucial to defining the roles of PGD2 (acting on DP1 and DP2 receptors) and PGE2 (on EP1 and EP4 receptors) in various inflammatory conditions; there are clear opportunities for therapeutic intervention. The vast endeavour on TP (thromboxane) antagonists is considered in relation to their limited pharmaceutical success in the cardiovascular area. Correspondingly, the clinical utility of IP (prostacyclin) antagonists is assessed in relation to the cloud hanging over the long-term safety of selective COX-2 inhibitors. Aspirin apart, COX inhibitors broadly suppress all prostanoid pathways, while high selectivity has been a major goal in receptor antagonist development; more targeted therapy may require an intermediate position with defined antagonist selectivity profiles. This review is intended to provide overviews of each antagonist class (including prostamide antagonists), covering major development strategies and current and potential clinical usage.

    The utility of Hyper Spectral Imaging (HSI) passive chemical detection employing wide field, standoff imaging continues to be advanced in detection applications. With a drive for reduced SWaP (Size, Weight, and Power), increased speed of detection and sensitivity, developing a handheld platform that is robust and user-friendly increases the detection capabilities of the end user. In addition, easy to use handheld detectors could improve the effectiveness of locating and identifying threats while reducing risks to the individual. ChemImage Sensor Systems (CISS) has developed the HSI Aperio™ sensor for real time, wide area surveillance and standoff detection of explosives, chemical threats, and narcotics for use in both government and commercial contexts. Employing liquid crystal tunable filter technology, the HSI system has an intuitive user interface that produces automated detections and real-time display of threats with an end user created library of threat signatures that is easily updated allowing for new hazardous materials. Unlike existing detection technologies that often require close proximity for sensing and so endanger operators and costly equipment, the handheld sensor allows the individual operator to detect threats from a safe distance. Uses of the sensor include locating production facilities of illegal drugs or IEDs by identification of materials on surfaces such as walls, floors, doors, deposits on production tools and residue on individuals. In addition, the sensor can be used for longer-range standoff applications such as hasty checkpoint or vehicle inspection of residue materials on surfaces or bulk material identification. The CISS Aperio™ sensor has faster data collection, faster image processing, and increased detection capability compared to previous sensors.

    Aims: Alcoholics Anonymous (AA) is the most prevalent 12-step mutual-help organization (MHO), yet debate has persisted clinically regarding whether patients whose primary substance is not alcohol should be referred to AA. Narcotics Anonymous (NA) was created as a more specific fit to enhance recovery from drug addiction; however, compared with AA, NA meetings are not as ubiquitous. Little is known about the effects of a mismatch between individuals' primary substance and MHOs, and whether any incongruence might result in a lower likelihood of continuation and benefit. More research would inform clinical recommendations. Method: Young adults (N = 279, M age 20.4, SD 1.6, 27% female; 95% White) in a treatment effectiveness study completed assessments at intake, and 3, 6, and 12 months post-treatment. A matching variable was created for ‘primary drug’ patients (i.e. those reporting cannabis, opiates or stimulants as primary substance; n = 198/279), reflecting the proportion of total 12-step meetings attended that were AA. Hierarchical linear models (HLMs) tested this variable's effects on future 12-step participation and percent days abstinent (PDA). Results: The majority of meetings attended by both alcohol and drug patients was AA. Drug patients attending proportionately more AA than NA meetings (i.e. mismatched) were no different than those who were better matched to NA with respect to future 12-step participation or PDA. Conclusion: Drug patients may be at no greater risk of discontinuation or diminished recovery benefit from participation in AA relative to NA. Findings may boost clinical confidence in making AA referrals for drug patients when NA is less available. PMID:25294352

    The purpose of this study was to develop a method to analyse the concentration of multiple illegal narcotics present in dietary supplements. To this end, we established and optimised a procedure using LC-MS/MS simultaneously to analyse 28 narcotic compounds in various forms of dietary supplements, including powders, tablets, liquids and capsules. In addition, candy and cookies that have also had detected cases of adulteration were also analysed. The specificity, linearity, accuracy, precision, limit of detection (LOD), limit of quantitation (LOQ), stability and recovery for these methods were validated accordingly. The LOD and LOQ of the LC-MS/MS ranged from 0.01-50.0 to 0.03-100 ng g(-1), respectively. The linearity of these results was good (r(2) > 0.99), with intra- and inter-day precision values of 0.2-5.2% and 0.2-4.8%, respectively. Further, the intra- and inter-day accuracies of this method were 97.0-103.4% and 94.6-103.1%, respectively. The stability RSD was less than 7.8%. The mean recovery for this LC-MS/MS procedure was 81.1-117.4%, with an RSD less than 9.8%. Following the validation of our method, we analysed 47 commercially available dietary supplements obtained in Korea. Whilst none of these samples had detectable amounts of the 28 specified narcotic adulterants, our novel LC-MS/MS procedure can be utilised comprehensively and continually to monitor illegal drug adulteration in various forms of dietary supplements.

    This paper was designed to describe the application of the method for solid-phase extraction of the medicinal and narcotic substances having different physicochemical composition by gas chromatography with mass-spectrometric detection (GC-MS) for the purpose of their screening in the blood. The solid-phase extraction technique was optimized by means of the Box-Behnken modeling with the evaluation of the influence on the effectiveness of extraction of various factors including pH of the buffer solution, eluent composition, the type and the volume of the solutions used to wash the sorbent.

    According to the opium law and prescription statute of 1930, physicians were duty-bound to maintain a stock ledger to allow a traceable record of the location of narcotic drugs. If a simplification of the prescription of opiates was welcomed 10 years ago then 2 years after amendment of the addictive drugs statute thought should be give to safe use, as can be concluded from a morphine logbook from the time of the introduction of the Federal opium law. "Receipt and issue... deliverer and recipient" must be able to be extracted from the documentation, which means the delivery and the dispensing but not the individual application.

  16. Antagonistic neural networks underlying differentiated leadership roles

    The emergence of two distinct leadership roles, the task leader and the socio-emotional leader, has been documented in the leadership literature since the 1950s. Recent research in neuroscience suggests that the division between task-oriented and socio-emotional-oriented roles derives from a fundamental feature of our neurobiology: an antagonistic relationship between two large-scale cortical networks – the task-positive network (TPN) and the default mode network (DMN). Neural activity in TPN tends to inhibit activity in the DMN, and vice versa. The TPN is important for problem solving, focusing of attention, making decisions, and control of action. The DMN plays a central role in emotional self-awareness, social cognition, and ethical decision making. It is also strongly linked to creativity and openness to new ideas. Because activation of the TPN tends to suppress activity in the DMN, an over-emphasis on task-oriented leadership may prove deleterious to social and emotional aspects of leadership. Similarly, an overemphasis on the DMN would result in difficulty focusing attention, making decisions, and solving known problems. In this paper, we will review major streams of theory and research on leadership roles in the context of recent findings from neuroscience and psychology. We conclude by suggesting that emerging research challenges the assumption that role differentiation is both natural and necessary, in particular when openness to new ideas, people, emotions, and ethical concerns are important to success.

  17. Endothelin receptor antagonists in pulmonary arterial hypertension.

    The endothelin (ET) system, especially ET-1 and the ET(A) and ET(B) receptors, has been implicated in the pathogenesis of pulmonary arterial hypertension (PAH). Together with prostanoids and phosphodiesterase 5 inhibitors, ET receptor antagonists have become mainstays in the current treatment of PAH. Three substances are currently available for the treatment of PAH. One of these substances, bosentan, blocks both ET(A) and ET(B) receptors, whereas the two other compounds, sitaxsentan and ambrisentan, are more selective blockers of the ET(A) receptor. There is ongoing debate as to whether selective or nonselective ET receptor blockade is advantageous in the setting of PAH, although there is no clear evidence that receptor selectivity is relevant with regard to the clinical effects of these drugs. For the time being, other features, such as safety profiles and the potential for pharmacokinetic interactions with other drugs used in the treatment of PAH, may be more important than selectivity or nonselectivity when selecting treatments for individual patients.

    An examination has been carried out on the relative efficacy of a number of chelating agents when acting as antagonists for oral cadmium chloride intoxication in mice. The compounds were administered orally after the oral administration of cadmium chloride at 1 mmol/kg. Of the compounds examined, several were useful in terms of enhancing survival, but by far the most effective in both enhancing survival and leaving minimal residual levels of cadmium in the liver and the kidney, was meso-2,3-dimercaptosuccinic acid (DMSA). Several polyaminocarboxylic acids also enhanced survival. The most effective of these in reducing liver and kidney levels of cadmium were diethylenetriaminepentaacetic acid (DTPA), trans-1,2-diaminocyclohexane-N,N,N'N'-tetraacetic acid (CDTA), and triethylenetetraminehexaacetic acid (TTHA). D-Penicillamine (DPA) was found to promote survival but also led to kidney cadmium levels higher than those found in the controls. Sodium 2,3-dimercaptopropane-1-sulfonate (DMPS) was as effective in promoting survival as DMSA but left levels of cadmium in the kidney and liver that were approximately four times greater than those found with DMSA.

    A recent uroselective alpha(1)-adrenoceptor antagonist, REC15/2739, has been joined with nitrooxy and furoxan NO-donor moieties to give new NO-donor alpha(1)-antagonists. All the compounds studied proved to be potent and selective ligands of human cloned alpha(1a)-receptor subtype. Derivatives 6 and 7 were able to relax the prostatic portion of rat vas deferens contracted by (-)-noradrenaline because of both their alpha(1A)-antagonist and their NO-donor properties.

    With the very recent market approval of pitolisant (Wakix®), the interest in clinical applications of novel multifunctional histamine H3 receptor antagonists has clearly increased. Since histamine H3 receptor antagonists in clinical development have been tested for a variety of different indications, the combination of pharmacological properties in one molecule for improved pharmacological effects and reduced unwanted side-effects is rationally based on the increasing knowledge on the complex neurotransmitter regulations. The polypharmacological approaches on histamine H3 receptor antagonists on different G-protein coupled receptors, transporters, enzymes as well as on NO-signaling mechanism are described, supported with some lead structures.
