Sample records for reduced abuse potential

  1. Abuse Potential of Pregabalin

    Schjerning, Ole; Rosenzweig, Mary; Pottegård, Anton;

    2016-01-01

    BACKGROUND: Several case reports and epidemiological studies have raised concern about the abuse potential of pregabalin, the use of which has increased substantially over the last decade. Pregabalin is, in some cases, used for recreational purposes and it has incurred attention among drug abusers...... for causing euphoric and dissociative effects when taken in doses exceeding normal therapeutic dosages or used by alternative routes of administration, such as nasal insufflation or venous injection. The magnitude of the abuse potential and the mechanism behind it are not fully known. OBJECTIVE: The...... aim of this study was to present a systematic review of the data concerning the abuse potential of pregabalin. METHODS: We performed a systematic literature search and reviewed the preclinical, clinical and epidemiological data on the abuse potential of pregabalin. RESULTS: We included preclinical (n...

  4. Carisoprodol: abuse potential and withdrawal syndrome.

    Reeves, Roy R; Burke, Randy S

    2010-03-01

    Carisoprodol (N-isopropyl-2 methyl-2-propyl-1,3-propanediol dicarbamate; N-isopropylmeprobamate) is a centrally acting skeletal muscle relaxant whose primary active metabolite is meprobamate, a substance with well established abuse potential similar to that of benzodiazepines. A number of reports show that carisoprodol has been abused for its sedative and relaxant effects, to augment or alter the effects of other drugs, and by the intentional combination of carisoprodol and other noncontrolled medications because of the relative ease (as compared to controlled substances) of obtaining prescriptions. The diversion and abuse of carisoprodol and its adverse health effects appear to have dramatically increased over the last several years. Clinicians have begun to see a withdrawal syndrome consisting of insomnia, vomiting, tremors, muscle twitching, anxiety, and ataxia in patients who abruptly cease intake of large doses of carisoprodol. Hallucinations and delusions may also occur. The withdrawal symptoms are very similar to those previously described for meprobamate withdrawal, suggesting that what may actually be occurring is withdrawal from meprobamate accumulated as a result of intake of excessive amounts of carisoprodol. However carisoprodol itself is capable of modulating GABA(A) function, and this may contribute both to the drugs abuse potential and to the occurrence of a withdrawal syndrome with abrupt cessation of intake. Carisoprodol has been classified as a controlled substance in several states in the US and restrictions on the use of the drug have been imposed in some European countries. Carisoprodol is metabolized to a controlled substance, has clear evidence of abuse potential and increasing incidence of abuse, and has shown evidence of a withdrawal syndrome with abrupt cessation from intake. This article will discuss the abuse potential of carisoprodol and the associated withdrawal syndrome, and consider implications for future use of the drug. PMID

  6. Childhood history of abuse and child abuse potential: the role of parent's gender and timing of childhood abuse.

    Romero-Martínez, A; Figueiredo, B; Moya-Albiol, L

    2014-03-01

    It has been suggested that being physically abused leads to someone becoming a perpetrator of abuse which could be associated to parents' gender, timing of the physical abuse and specific socio-demographic variables. This study aims to investigate the role the parents' gender, timing of childhood abuse and socio-demographic variables on the relationship between parents' history of childhood physical abuse and current risk for children. The sample consisted of 920 parents (414 fathers, 506 mothers) from the Portuguese National Representative Study of Psychosocial Context of Child Abuse and Neglect who completed the Childhood History Questionnaire and the Child Abuse Potential Inventory. The results showed that fathers had lower current potential risk of becoming physical abuse perpetrators with their children than mothers although they did not differed in their physical victimization history. Moreover, the risk was higher in parents (both genders) with continuous history of victimization than in parents without victimization. Prediction models showed that for fathers and mothers separately similar socio-demographic variables (family income, number of children at home, employment status and marital status) predicted the potential risk of becoming physical abuses perpetrators. Nevertheless, the timing of victimization was different for fathers (before 13 years old) and mothers (after 13 years old). Then our study targets specific variables (timing of physical abuse, parents' gender and specific socio-demographic variables), which may enable professionals to select groups of parents at greater need of participating in abuse prevention programs.

  11. Formulation considerations for the development of medications with abuse potential.

    Mansbach, Robert S; Moore, Richard A

    2006-06-01

    The availability of increasingly sophisticated drug formulations and delivery devices has created new opportunities in drug development. These newer approaches can result in improved drug bioavailability, or they can alter key pharmacokinetic parameters in such a way as to decrease dosing interval, decrease variability, or blunt maximal concentrations that are associated with adverse events of particular concern. Special formulations or devices can also provide for easier or more convenient dosing in subpopulations of interest, such as children or the elderly. Although the key principles of abuse potential assessment and the underlying neurochemistry and pharmacology are relatively well understood, evaluation of the influences of drug formulation have received much less study. Because dose and formulation - and even the therapeutic indication - are refined over the course of development, it is usually difficult to conduct more than a cursory evaluation of the influence of formulation on the underlying abuse potential of the active pharmaceutical ingredient. Industrial sponsors would benefit from further research in areas of formulation science and pharmacokinetics that would improve the predictability of prescription drug abuse. In particular, validation of new pharmacokinetic parameters and standardization of methods to understand the consequences of product tampering could assist in gaining a better assessment of risk for controlled release formulations. Such methods could apply not only to innovator products, but also to those wishing to develop generic versions with similar pharmaceutical performance. This article proposes several factors that may be of use to industrial sponsors in making formulation choices for drugs with the potential for abuse. PMID:16472940

  12. Linking child maltreatment history with child abuse potential: Relative roles of maltreatment types

    Mitkovic-Voncina Marija

    2014-01-01

    Full Text Available The independent roles of each childhood maltreatment type on child abuse potential in adults have been insufficiently explored and are inconsistent, with dissociation as one of the possible suggested mediators of intergenerational child abuse. We investigated these effects among 164 non-clinical adult parents, who filled in general questionnaires: Childhood Trauma Questionnaire (CTQ, Child Abuse Potential Inventory (CAPI and Dissociative Experience Scale (DES. Among all maltreatment types (emotional, physical and sexual abuse, emotional and physical neglect, emotional abuse was the only independent predictor in the regression model of child abuse potential. The relationship between emotional abuse history and child abuse potential was partially mediated by dissociation. The findings could speak in favor of the potentially unique detrimental role of emotional abuse in intergenerational maltreatment, with dissociation as one of the possible mechanisms.

  14. Carisoprodol: update on abuse potential and legal status.

    Reeves, Roy R; Burke, Randy S; Kose, Samet

    2012-11-01

    Carisoprodol is a centrally acting skeletal muscle relaxant of which meprobamate, a controlled substance, is the primary active metabolite. The abuse of carisoprodol has increased dramatically in the last several years. A withdrawal syndrome occurs in some patients who abruptly cease carisoprodol intake. The symptoms of this syndrome are similar to those seen with meprobamate withdrawal, suggesting that they may result from withdrawal from meprobamate accumulated with intake of excessive carisoprodol; however, carisoprodol is capable of modulating GABAA function, which may contribute to its abuse potential.There has been considerable debate about whether carisoprodol should be considered a controlled substance. Carisoprodol was removed from the market in Norway on May 1, 2008, but may still be used by specially approved patients. Carisoprodol was classified as a controlled substance in several US states, and effective January 11, 2012, became a schedule IV controlled substance at the US federal level. This article updates the literature on abuse potential and examines recent developments regarding the legal status of carisoprodol. PMID:23128807

  19. Assessment of the Abuse Potential of the Orexin Receptor Antagonist, Suvorexant, Compared With Zolpidem in a Randomized Crossover Study.

    Schoedel, Kerri A; Sun, Hong; Sellers, Edward M; Faulknor, Janice; Levy-Cooperman, Naama; Li, Xiaodong; Kennedy, William P; Cha, Jang-Ho; Lewis, Nicole M; Liu, Wen; Bondiskey, Phung; McCrea, Jacqueline B; Panebianco, Deborah L; Troyer, Matthew D; Wagner, John A

    2016-08-01

    Suvorexant is a dual orexin receptor antagonist approved in the United States and Japan for the treatment of insomnia at a maximum dose of 20 mg. This randomized double-blind crossover study evaluated the abuse potential of suvorexant in 36 healthy recreational polydrug users with a history of sedative and psychedelic drug use. Single doses of suvorexant (40, 80, and 150 mg: 2-7.5 × maximum dose), zolpidem (15 and 30 mg: 1.5-3 × maximum dose), and placebo were administered, with a 10-day washout between treatments. Subjective and objective measures, including visual analog scales (VASs), Addiction Research Center Inventory, and cognitive/psychomotor tests, were evaluated for 24-hour postdose. Suvorexant had significantly greater peak effects on "drug liking" VAS (primary endpoint) than placebo. Although effects of suvorexant on abuse potential measures were generally similar to zolpidem, they remained constant across doses, whereas zolpidem often had greater effects at higher doses. Suvorexant (all doses) had significantly fewer effects than zolpidem 30 mg on secondary measures, such as "high" VAS, Bowdle VAS, and Addiction Research Center Inventory morphine-benzedrine group. The overall incidence of abuse-related adverse events, such as euphoric mood and hallucination, was numerically lower with suvorexant than zolpidem. In agreement with its classification as a schedule IV drug, suvorexant demonstrated abuse potential, compared with placebo. The abuse potential was similar to zolpidem using certain measures, but with a reduced incidence of abuse-related adverse events. Although this suggests that the overall abuse liability of suvorexant may be lower than zolpidem, the actual abuse rates will be assessed with the postmarketing experience. PMID:27253658

  20. A GENTLER GESTALT THERAPY: ON REDUCING STIMULATION IN ADULT SURVIVORS OF ABUSE

    Andrew Lapides

    2012-01-01

    Adult survivors of abuse require a slower progression in treatment. Profoundly abused patients suffering from pre-oedipal conditions may become overstimulated using gestalt methods. This paper will focus on reducing stimulation in the patient using methods borrowed from modern psychoanalysis, which was developed by Hyman Spotnitz. The author argues for a combined approach that emphasizes support rather then frustration in the development of the treatment process.

  1. 11β-hydroxysteroid dehydrogenase inhibition as a new potential therapeutic target for alcohol abuse.

    Sanna, P P; Kawamura, T; Chen, J; Koob, G F; Roberts, A J; Vendruscolo, L F; Repunte-Canonigo, V

    2016-01-01

    The identification of new and more effective treatments for alcohol abuse remains a priority. Alcohol intake activates glucocorticoids, which have a key role in alcohol's reinforcing properties. Glucocorticoid effects are modulated in part by the activity of 11β-hydroxysteroid dehydrogenases (11β-HSD) acting as pre-receptors. Here, we tested the effects on alcohol intake of the 11β-HSD inhibitor carbenoxolone (CBX, 18β-glycyrrhetinic acid 3β-O-hemisuccinate), which has been extensively used in the clinic for the treatment of gastritis and peptic ulcer and is active on both 11β-HSD1 and 11β-HSD2 isoforms. We observed that CBX reduces both baseline and excessive drinking in rats and mice. The CBX diastereomer 18α-glycyrrhetinic acid 3β-O-hemisuccinate (αCBX), which we found to be selective for 11β-HSD2, was also effective in reducing alcohol drinking in mice. Thus, 11β-HSD inhibitors may be a promising new class of candidate alcohol abuse medications, and existing 11β-HSD inhibitor drugs may be potentially re-purposed for alcohol abuse treatment.

    Full Text Available The aim of this review paper is to identify the important role of teachers about reporting child abuse in their classroom to reduce and prevention of child abuse with considers the homeless students. The findings of this study show that teachers have an important role to intervene and prevent of child abuse, because they spend a lot of time with students and contact with them in classroom. This study also finds that, teachers believed that the appropriate training has not been taught them in colleges, universities or teachers training centers. Furthermore, this paper pursues the professional abilities of teachers in order to find the child abuse signs of their students as well as the homeless ones and the skills of reporting them.

  6. Opportunities for Exploring and Reducing Prescription Drug Abuse Through Social Media.

    Scott, Kevin R; Nelson, Lewis; Meisel, Zachary; Perrone, Jeanmarie

    2015-01-01

    The rising toll of opioid overdoses in the past decade has been declared a prescription drug epidemic by the Centers for Disease Control. In that same period, Internet platforms, such as Facebook and Twitter, have grown exponentially, being used primarily by a population similar to new initiates of substance abuse. Researchers have utilized social media to gain insights into use patterns and prevailing attitudes about various substances. Social media has potential to enhance screening, prevention, and treatment of addiction. With future funding, they should be leveraged to advance understanding of prescription drug use and improve treatment and prevention of abuse. PMID:26075802

  7. Adolescent cocaine abuse. Addictive potential, behavioral and psychiatric effects.

    Estroff, T W; Schwartz, R H; Hoffmann, N G

    1989-12-01

    Four hundred seventy-nine drug abusing adolescent patients enrolled in seven Straight, Inc. Adolescent Drug-Abuse Treatment Programs in five geographic regions across the United States were studied to determine the severity and patterns of cocaine abuse. Of these, 341 admitted to cocaine use and became part of this survey. Cocaine use was categorized as heavy, intermediate, or light. Areas examined were the addictive spectrum, psychosocial dysfunction, and psychiatric symptoms. Intermediate and heavy users of cocaine abused significantly less marijuana and inhalants than light cocaine abusers. Heavy and intermediate users were more likely to use cocaine intravenously and to use crack. They developed tachyphylaxis more frequently, progressed to weekly use in less than 3 months more frequently, and became preoccupied with obtaining and using cocaine significantly more frequently. They used more sedative hypnotics to calm themselves and engaged in more criminal behavior, such as stealing from parents and stores and passing bad checks. They had more arrests for possession of drugs, stole more cars, sold more drugs, and were more likely to trade sexual favors to obtain the drug. Heavy and intermediate users were significantly more psychiatrically disturbed than light users, becoming more suspicious, nervous, aggressive, and demonstrating increased symptoms of fatigue, sleeplessness, decreased appetite, and increasing cocaine dysphoria. All of these symptoms could be mistaken for psychiatric disorders. This study suggests that cocaine is as addictive in adolescents as in adults; possibly more so. It also causes psychosocial dysfunction and psychiatric symptoms. Further research into cocaine addiction among adolescents is indicated. PMID:2582695

  8. Potential and Dunkelfeld offenders: two neglected target groups for prevention of child sexual abuse.

    Schaefer, Gerard A; Mundt, Ingrid A; Feelgood, Steven; Hupp, Elena; Neutze, Janina; Ahlers, Christoph J; Goecker, David; Beier, Klaus M

    2010-01-01

    Little is known about men who have not yet committed child sexual abuse but may be at risk of doing so (potential offenders) and the factors that distinguish these men from undetected child sexual abuse offenders with a sexual interest in children (Dunkelfeld offenders). The present study describes and compares potential and Dunkelfeld offenders, which can be viewed as ideal target groups for (primary) prevention efforts with respect to child sexual abuse. Also, this study seeks to demonstrate the feasibility of using a telephone screening procedure to conduct research with these groups. Using a computer assisted telephone interview (CATI), data on demographics, mental health, sexuality, criminal history, and victim characteristics were collected from respondents in a nation-wide media campaign, which informed potential (re-)offenders of child sexual abuse of a research and treatment project. Many participants reported recurrent sexual fantasies involving minors, as well as related distress, suggesting a high prevalence of pedophilia and hebephilia. More than half feared they would sexually abuse a minor, and Dunkelfeld offenders reported 3.2 victims on average. Group comparisons revealed that Dunkelfeld offenders were, for example, more likely to perceive themselves being at risk of offending, compared to potential offenders. The results suggest that targeting potential and Dunkelfeld offenders could prove a worthwhile approach in the prevention of child sexual abuse. PMID:20466423

  10. Is Web-Based Education Effective in Reducing Belief Toward Drug Abuse Among College Students?

    Jalilian

    2015-02-01

    Full Text Available Background Addiction is considered a basic structural problem in modern society, and seems to reach an epidemic scale in the last decades. Choosing a method to fulfill the intervention is an important issue to conduct educational interventions to prevent addictive behaviors. In this regard, web-based education has been widely used to introduce preventive programs to risky behaviors during recent years. Objectives The aim of the present study was to investigate the impact of web-based education intervention to decrease positive beliefs encouraging drug abuse among male medical college students. Patients and Methods This was a prospective-retrospective intervention study that was conducted among 75 male students in Kermanshah University of Medical Sciences, Kermanshah, Iran, during 2014. t-test was used for the statistical analysis. Results Our findings indicated that the belief toward drug abuse was significantly reduced after education (P = 0.003. In addition, compared pre and post-intervention scores on survey items showed a significant reduction in enjoyment, improve energy, attraction, higher strength, and higher self-esteem items after education (P 0.05. Conclusions Our findings showed that designing and implementing web-based educational intervention could be effective to reduce the positive beliefs toward drug abuse among college students.

  11. Parent-child aggression: association with child abuse potential and parenting styles.

    Rodriguez, Christina M

    2010-01-01

    The present investigation predicted that greater use of corporal punishment as well as physical maltreatment would be associated with child abuse potential and selected parenting styles. Three independent studies were examined, two with community samples and a third with a clinical at-risk sample of parents. Parents across all studies anonymously completed the Child Abuse Potential Inventory, the Parent-Child Conflict Tactics Scale to assess physical discipline and maltreatment, as well as the Parenting Scale to measure dysfunctional parenting styles. Findings support that overall parent-child aggression, as well as physical maltreatment behaviors specifically, were associated with child abuse potential. Parent-child aggression was also related to dysfunctional parenting styles, particularly an overreactive, authoritarian parenting style. Permissive parenting was also identified as potentially associated with physical maltreatment, although the findings regarding such lax parenting styles are less clear. Intriguing findings emerged regarding the connection of psychological aggression to both child abuse potential and dysfunctional parenting style. Child abuse potential was also associated with dysfunctional parenting style, particularly harsh, overreactive approaches. Recommendations for future study with at-risk samples and additional research on permissive parenting and psychological aggression are discussed. PMID:21287963

  12. A prospective study of the potential moderating role of social support in preventing marginalization among individuals exposed to bullying and abuse in junior high school.

    Strøm, Ida Frugård; Thoresen, Siri; Wentzel-Larsen, Tore; Sagatun, Åse; Dyb, Grete

    2014-10-01

    Negative physical and psychological long-term consequences of abuse and bullying are well documented. It is reasonable to assume that abuse and bullying early in life also may have an impact on the ability to work and stay economically independent later in life, but such prospective studies are lacking. This study investigates the consequences of exposure to abuse and bullying in junior high school, as measured by receiving long-term social welfare benefits in young adulthood. In addition, it explores the potential protective role of social support. Self-reported data from 13,633 (50.3% female) junior high school students were linked to registry data on their use of social welfare benefits from the age of 18 and for eight consecutive years. Cox regression analyses were applied to test the relationship between exposure to life adversities and the use of social welfare benefits, and the potential moderating role of social support. The analyses showed that individuals exposed to abuse and bullying had an increased likelihood of receiving social-welfare benefits compared with individuals not exposed to these types of abuse. Exposure to multiple types of abuse led to a higher likelihood of using social welfare benefits compared with single types of abuse and no abuse. The findings on the potential moderating role of social support were mixed, depending on the source of social support. Family support and classmate relationships were protective in reducing the likelihood of the use of social welfare benefits, whereas peer and teachers' support showed inconsistent patterns. These results are promising in terms of preventing the long-term negative consequences of abuse and bullying. PMID:24985489

  15. Endomorphin analog analgesics with reduced abuse liability, respiratory depression, motor impairment, tolerance, and glial activation relative to morphine.

    Zadina, James E; Nilges, Mark R; Morgenweck, Jenny; Zhang, Xing; Hackler, Laszlo; Fasold, Melita B

    2016-06-01

    Opioids acting at the mu opioid receptor (MOR) are the most effective analgesics, however adverse side effects severely limit their use. Of particular importance, abuse liability results in major medical, societal, and economic problems, respiratory depression is the cause of fatal overdoses, and tolerance complicates treatment and increases the risk of side effects. Motor and cognitive impairment are especially problematic for older adults. Despite the host of negative side effects, opioids such as morphine are commonly used for acute and chronic pain conditions. Separation of analgesia from unwanted effects has long been an unmet goal of opioid research. Novel MOR agonist structures may prove critical for greater success. Here we tested metabolically stable analogs of the endomorphins, endogenous opioids highly selective for the MOR. Compared to morphine, the analogs showed dramatically improved analgesia-to-side-effect ratios. At doses providing equal or greater antinociception than morphine in the rat, the analogs showed reduced a) respiratory depression, b) impairment of motor coordination, c) tolerance and hyperalgesia, d) glial p38/CGRP/P2X7 receptor signaling, and e) reward/abuse potential in both conditioned place preference and self-administration tests. Differential effects on glial activation indicate a mechanism for the relative lack of side effects by the analogs compared to morphine. The results suggest that endomorphin analogs described here could provide gold standard pain relief mediated by selective MOR activation, but with remarkably safer side effect profiles compared to opioids like morphine.

  18. Mental Health Services and Public Safety: Substance Abuse Outpatient Visits Were Associated with Reduced Crime Rates in a Swedish Cohort.

    Natalie Durbeej

    Full Text Available Substance abuse is related to offending and substance abuse treatment has been associated with reductions in criminal behavior. This cohort study aimed to explore the relationship between participation in substance abuse interventions and general criminal recidivism among offenders with a combination of mental health problems and substance use problems. In total, 150 Swedish offenders with self-reported mental health and substance use problems were followed for approximately three years with regard to participation in substance abuse interventions and criminal recidivism. Participants with at least three planned visits to specialized outpatient substance abuse clinics had a substantially reduced risk of reoffending as compared to those with fewer than three such visits (HR = 0.47, 95% CI 0.29-0.77. For those with at least three planned visits, general criminal recidivism was reduced by 75% during periods of participation in outpatient visits, as compared to periods of non-participation (HR = 0.25, 95% CI 0.11-0.60. For offenders with mental health problems and substance use problems, outpatient substance abuse interventions could be regarded as important from a clinical risk management perspective, and be encouraged.

  20. Geriatric forensics - Part 2 "Prevalence of elder abuse and their potential forensic markers among medical and dental patients"

    Khurshid A Mattoo

    2015-01-01

    Full Text Available Context: This study is a continuation of the earlier studies and has been extended to investigate the potential forensic markers of elder abuse. Aims: To determine the prevalence of elder abuse in various outpatient departments (OPDs. To study the associated parameters related to the abuser and the abused. To determine the existence of potential forensic markers of elder abuse. Settings and Design: The subjects were randomly selected from the medical and the dental OPDs of the university. Materials and Methods: Eight hundred and thirty two elderly subjects in the age range 40-60 years were interviewed using a questionnaire to determine the existence of elder abuse. The subjects were investigated and examined for weight, nutrition and hydration, vital signs, habits, existing visual and auditory capabilities, medications, disclosure of wills/deeds, signs of depression, and documented cleanliness. The mini-mental state examination, the Geriatric Depression Scale, the Clock drawing test, and the Brief Psychiatric Rating Scale were used to determine the potential forensic markers. Statistical Analysis Used: Mean values in percentage were determined by dividing the number of determined subjects by the total number of subjects for that parameter. Results: About 37% in medical and 41% in dental OPDs were found to have suffered from abuse, mostly in the age group 60-70 years. Females received more abuse and a combination of son and daughter-in-law constituted most abusers. Various potential markers of elder abuse and neglect investigated among the elder abuse victims included depression (89%, signs of improper feeding (83%, changes in personal hygiene (69%, need for medical/dental treatment (78%, medication misuse (67%, changes in wills/deeds (26%, decubiti (10%, bruises (17%, skin tears (27%, and confusion (23%. Conclusions: Elder abuse exists in one or more forms in both medical and dental OPDs among both males and females in all age groups.

  3. The potential for misuse and abuse of medications in ADHD: a review.

    Clemow, David B; Walker, Daniel J

    2014-09-01

    This article reviews the literature concerning attention-deficit/hyperactivity disorder (ADHD) medication misuse, abuse, dependence, diversion, and malingering. The review covers nonmedical use (NMU) of both stimulant (methylphenidate and amphetamine) and nonstimulant (α-adrenergic agonists and atomoxetine) prescription medications, and provides a discussion on the relevance for ADHD treatment today. The neural basis for ADHD medication mechanisms of action (increased norepinephrine and dopamine signaling) and their neurobiochemical relationship to the abuse potential is explored. Regionally-specific, stimulant-induced elevations in brain dopamine appear to be integral to both efficacy in ADHD and potential for abuse. In addition to the prevalence of misuse and diversion, additional topics discussed include the potential safety concerns associated with NMU of prescription ADHD medications and the cost to payers of prescription drug diversion (eg, increased emergency department visits associated with misuse). The evidence describing the difficulty in detecting malingering for the purpose of illicit access to ADHD medications for subsequent misuse or diversion is also summarized. Moreover, the effect of ADHD medications in patients with comorbid substance use disorder and the controversial potential linkage of stimulant prescription use with subsequent substance use disorder are explored. Overall, the data suggest that ADHD medication misuse and diversion are common health care problems for stimulant medications, with the prevalence believed to be approximately 5% to 10% of high school students and 5% to 35% of college students, depending on the study. Stimulant effectiveness and speed of action are deemed desirable to enhance attention and focus performance for activities like studying, but stimulants are also misused recreationally. Conversely, the data suggest a lack of abuse potential and lack of actual medication misuse for the nonstimulant medications

  5. Cyclohexane, a Potential Drug of Abuse with Pernicious Effects on the Brain.

    Campos-Ordonez, Tania; Gonzalez-Perez, Oscar

    2015-01-01

    Cyclohexane is a volatile solvent used as a harmless substitute for dangerous organic solvents in several products, such as paint thinners, gasoline and adhesives. Many of these products are used as drugs of abuse and can severely damage neural tissue and impair neurological functions. However, there is very little information on the effects of cyclohexane on the brain. In humans, cyclohexane produces headaches, sleepiness, dizziness, limb weakness, motor changes, and verbal memory impairment. Recent studies in mice have demonstrated behavioral alterations, reactive gliosis, microglial reactivity, and oxidative stress in the brains of cyclohexane-exposed animals. This indicates that cyclohexane may represent a potential problem for public health. Therefore, studies are needed to clarify the neurobiological effects of this volatile compound, including the cellular and molecular mechanisms of neurotoxicity, and to minimize the human health risk posed by the intentional or accidental inhalation of this potential drug of abuse.

  6. Detection of conscious deception using the Child Abuse Potential Inventory lie scale.

    Robertson, W K; Milner, J S

    1985-10-01

    Two studies were conducted to provide data on the construct validity of the Child Abuse Potential Inventory lie scale. In Study One, 187 male and female undergraduate students were administered either the Child Abuse Potential Inventory, the Marlowe-Crowne Social Desirability Scale, or the Unlikely Virtues Scale. Three instructional sets were provided: respond honestly, distort responses in a positive manner, and distort responses in a negative manner. Each scale successfully discriminated between subjects in the honest and faking good conditions. Only the Marlowe-Crowne scale discriminated subjects in the faking bad condition through their low scores. No gender differences were observed as a function of instructional set or test employed. In Study Two, 31 male and female parents were given the CAP-Inventory under the same instructional sets provided in Study One. The findings for the parent group, the population the CAP-Inventory was designed to be employed with, replicated the results found in Study One. PMID:4067804

    Full Text Available Few interventions have targeted perceived stress as a co-occurring construct central to substance use and subsequent HIV/AIDS risk reduction among African American urban young adults. The Color It Real Program was a seven session, weekly administered age-specific and culturally-tailored intervention designed to provide substance abuse and HIV education and reduce perceived stress among African Americans ages 18 to 24 in Atlanta, GA. Effectiveness was assessed through a quasi-experimental study design that consisted of intervention (n = 122 and comparison (n = 70 groups completing a pre- and post-intervention survey. A series of Analysis of Variance (ANOVA tests were used to assess pre- to post-intervention changes between study groups. For intervention participants, perceived stress levels were significantly reduced by the end of the intervention (t(70 = 2.38, p = 0.020, condom use at last sexual encounter significantly increased (F = 4.43, p = 0.0360, intervention participants were significantly less likely to drink five or more alcoholic drinks in one sitting (F = 5.10, p = 0.0245, and to use clean needles when injecting the drug (F = 36.99, p = 0.0001. This study is among the first of its kind to incorporate stress management as an integral approach to HIV/SA prevention. The program has implications for the design of other community-based, holistic approaches to addressing substance use and risky behaviors for young adults.

    2013-11-01

    In the reward circuitry of the brain, α-7-nicotinic acetylcholine receptors (α7nAChRs) modulate effects of Δ(9)-tetrahydrocannabinol (THC), marijuana's main psychoactive ingredient. Kynurenic acid (KYNA) is an endogenous negative allosteric modulator of α7nAChRs. Here we report that the kynurenine 3-monooxygenase (KMO) inhibitor Ro 61-8048 increases brain KYNA levels and attenuates cannabinoid-induced increases in extracellular dopamine in reward-related brain areas. In the self-administration model of drug abuse, Ro 61-8048 reduced the rewarding effects of THC and the synthetic cannabinoid WIN 55,212-2 in squirrel monkeys and rats, respectively, and it also prevented relapse to drug-seeking induced by reexposure to cannabinoids or cannabinoid-associated cues. The effects of enhancing endogenous KYNA levels with Ro 61-8048 were prevented by positive allosteric modulators of α7nAChRs. Despite a clear need, there are no medications approved for treatment of marijuana dependence. Modulation of KYNA offers a pharmacological strategy for achieving abstinence from marijuana and preventing relapse. PMID:24121737

  13. Abuse Potential of Soma: the GABA(A) Receptor as a Target.

    Gonzalez, Lorie A; Gatch, Michael B; Forster, Michael J; Dillon, Glenn H

    2009-01-01

    Soma(®) (carisoprodol) is an increasingly abused, centrally-acting muscle relaxant. Despite the prevalence of carisoprodol abuse, its mechanism of action remains unclear. Its sedative effects, which contribute to its therapeutic and recreational use, are generally attributed to the actions of its primary metabolite, meprobamate, at GABA(A) receptors (GABA(A)R). Meprobamate is a controlled substance at the federal level; ironically, carisoprodol is not currently classified as such. Using behavioral and molecular pharmacological approaches, we recently demonstrated carisoprodol, itself, is capable of modulating GABA(A)R function in a manner similar to central nervous system depressants. Its functional similarities with this highly addictive class of drugs may contribute to the abuse potential of carisoprodol. The site of action of carisoprodol has not been identified; based on our studies, interaction with benzodiazepine or barbiturate sites is unlikely. These recent findings, when coupled with numerous reports in the literature, support the contention that the non-controlled status of carisoprodol should be reevaluated. PMID:20419052

    College alcohol abuse continues as a major public-health concern. Theory-driven research is necessary to address the severe negative consequences of this college drinking. One theory that offers particular promise is the theory of planned behavior (TPB). This theory posits that attitudes, perceived behavioral control, subjective norms, and intentions are the causal underpinnings of behavior. The current research investigates the utility of this theory in predicting college-student drinkin...

  2. Evaluation of the acute behavioral effects and abuse potential of a C8-C9 isoparaffin solvent.

    Balster, R L; Bowen, S E; Evans, E B; Tokarz, M E

    1997-07-01

    We hypothesized that the abuse potential of certain types of inhalants could be evaluated in animals by determining the overlap in their profile of behavioral effects with that of CNS depressant drugs and other depressant-like abused inhalants. For our first attempt in evaluating a solvent with an unknown abuse potential we tested ISOPAR-E. ISOPAR-E is a mixture of predominantly C8-C9 isoparaffinic hydrocarbons that is being used more and more frequently as a solvent in industrial and consumer products, including, but not limited to, typewriter correction fluids. Presently, nothing is known about the potential for abuse of products containing this solvent. In the present studies, we compared the volatility of ISOPAR-E and the abused solvent 1,1,1-trichloroethane (TCE) in our exposure systems. Additionally, five behavioral procedures were conducted in mice to compare the effects of the two compounds. The results demonstrate that: (1) ISOPAR-E was less volatile than TCE; (2) ISOPAR-E produced a somewhat different profile of effects than did TCE as assessed with a functional observational battery; (3) unlike TCE, ISOPAR-E did not affect performance on tests of motor coordination; (4) TCE and ISOPAR-E produced concentration-related decreases in schedule-controlled operant performance with recovery from TCE being somewhat more rapid; (5) ISOPAR-E produced cross dependence in TCE-dependent mice; and (6) both TCE and ISOPAR-E produced substantial levels of ethanol-lever responding in a drug discrimination procedure, although the ethanol-like effects of ISOPAR-E only occurred at response rate decreasing concentrations. Overall, there was a poorer separation of behavioral and lethal concentrations for ISOPAR-E than for TCE. Although a somewhat different profile of behavioral effects was obtained with ISOPAR-E and TCE, we cannot say with certainty if enough similarities exist with abused inhalants to predict that ISOPAR-E would be subject to depressant-like abuse

  8. Reduced metabolism in brain "control networks" following cocaine-cues exposure in female cocaine abusers.

    Nora D Volkow

    Full Text Available OBJECTIVE: Gender differences in vulnerability for cocaine addiction have been reported. Though the mechanisms are not understood, here we hypothesize that gender differences in reactivity to conditioned-cues, which contributes to relapse, are involved. METHOD: To test this we compared brain metabolism (using PET and ¹⁸FDG between female (n = 10 and male (n = 16 active cocaine abusers when they watched a neutral video (nature scenes versus a cocaine-cues video. RESULTS: Self-reports of craving increased with the cocaine-cue video but responses did not differ between genders. In contrast, changes in whole brain metabolism with cocaine-cues differed by gender (p<0.05; females significantly decreased metabolism (-8.6%±10 whereas males tended to increase it (+5.5%±18. SPM analysis (Cocaine-cues vs Neutral in females revealed decreases in frontal, cingulate and parietal cortices, thalamus and midbrain (p<0.001 whereas males showed increases in right inferior frontal gyrus (BA 44/45 (only at p<0.005. The gender-cue interaction showed greater decrements with Cocaine-cues in females than males (p<0.001 in frontal (BA 8, 9, 10, anterior cingulate (BA 24, 32, posterior cingulate (BA 23, 31, inferior parietal (BA 40 and thalamus (dorsomedial nucleus. CONCLUSIONS: Females showed greater brain reactivity to cocaine-cues than males but no differences in craving, suggesting that there may be gender differences in response to cues that are not linked with craving but could affect subsequent drug use. Specifically deactivation of brain regions from "control networks" (prefrontal, cingulate, inferior parietal, thalamus in females could increase their vulnerability to relapse since it would interfere with executive function (cognitive inhibition. This highlights the importance of gender tailored interventions for cocaine addiction.

  9. Reduced Metabolism in Brain 'Control Networks' Following Cocaine-Cues Exposure in Female Cocaine Abusers

    Gender differences in vulnerability for cocaine addiction have been reported. Though the mechanisms are not understood, here we hypothesize that gender differences in reactivity to conditioned-cues, which contributes to relapse, are involved. To test this we compared brain metabolism (using PET and 18FDG) between female (n = 10) and male (n = 16) active cocaine abusers when they watched a neutral video (nature scenes) versus a cocaine-cues video. Self-reports of craving increased with the cocaine-cue video but responses did not differ between genders. In contrast, changes in whole brain metabolism with cocaine-cues differed by gender (p<0.05); females significantly decreased metabolism (-8.6% ± 10) whereas males tended to increase it (+5.5% ± 18). SPM analysis (Cocaine-cues vs Neutral) in females revealed decreases in frontal, cingulate and parietal cortices, thalamus and midbrain (p<0.001) whereas males showed increases in right inferior frontal gyrus (BA 44/45) (only at p<0.005). The gender-cue interaction showed greater decrements with Cocaine-cues in females than males (p<0.001) in frontal (BA 8, 9, 10), anterior cingulate (BA 24, 32), posterior cingulate (BA 23, 31), inferior parietal (BA 40) and thalamus (dorsomedial nucleus). Females showed greater brain reactivity to cocaine-cues than males but no differences in craving, suggesting that there may be gender differences in response to cues that are not linked with craving but could affect subsequent drug use. Specifically deactivation of brain regions from 'control networks' (prefrontal, cingulate, inferior parietal, thalamus) in females could increase their vulnerability to relapse since it would interfere with executive function (cognitive inhibition). This highlights the importance of gender tailored interventions for cocaine addiction.

  14. A feasibility test of a brief motivational interview intervention to reduce dating abuse perpetration in a hospital setting

    Rothman, Emily F.; Wang, Na

    2016-01-01

    Objective To describe the intervention development process and feasibility testing of a hospital-based brief intervention to reduce the perpetration of adolescent dating abuse (ADA). To our knowledge, this intervention is the first to focus exclusively on ADA perpetration reduction via a motivational interview-type intervention in this setting. Method The rationale for and the six Intervention Mapping steps used to generate the intervention are described. Feasibility is conceptualized as intervention acceptability, demand, implementation, practicality, integration, and limited-efficacy. Results The Real Talk intervention was integrated smoothly into the emergency department setting. Participants did not experience any negative impact, and the vast majority (86%) reported that they felt helped. Quantitative assessments suggest that the intervention reduced the number of participants in the pre-contemplation stage of change regarding their use of relationship violence, and may have moved them forward into the action stage. Real Talk participants were more likely than those in the control group to tell friends to help them stay calm around their partner after drinking alcohol, and to talk with their doctor to get help for their problems. Conclusions Real Talk was developed to meet an unmet need for tertiary ADA interventions in non-school settings. It was developed in accordance with a recommended framework, informed by theory, and subsequently tested for feasibility. Feasibility assessment results suggest that Real Talk can be implemented in health care settings and may influence attitudinal and behavioral outcomes in the desired directions.

  16. Potential Drug Combinations to Reduce Cardiovascular Disease Burden in Diabetes.

    Pillarisetti, Sivaram

    2016-03-01

    The major cause of death and complications in patients with type 2 diabetes (T2DM) is cardiovascular disease (CVD). More than 60% of all patients with T2DM die of CVD, and an even greater percentage have serious complications. The impact of glucose lowering on cardiovascular complications is a hotly debated issue and recent large clinical trials reported no significant decrease in cardiovascular events with intensive glucose control. Risk remains high even after correcting diabetes-associated dyslipidemia with drugs such as fibrates and niacin. Data from several clinical studies show that postprandial glucose and lipids have a strong predictive value on myocardial infarction (MI) and mortality. However, strategies to reduce postprandial hyperglycemia and/or lipemia through increased utilization of glucose and/or triglycerides (TG) have been shown to not be effective in reducing the CVD burden. In this review, I discus the preferred ways to reduce postprandial glucose and TG with combinations of currently marketed drugs with potential benefit in CVD. PMID:26719218

    Full Text Available Abstract Background This study describes the continuation of a program to constrain health care costs by limiting inpatient hospital programs among the hospitals of Syracuse, New York. Through a community demonstration project, it identified components of individual hospital programs for reduction of complications and their impact on the frequency and rates of these outcomes. Findings This study involved the implementation of interventions by three hospitals using the Potentially Preventable Complications System developed by 3M™ Health Information Systems. The program is noteworthy because it included competing hospitals in the same community working together to reduce adverse patient outcomes and related costs. The study data identified statistically significant reductions in the frequency of high and low volume complications during the three year period at two of the hospitals. At both of these hospitals, aggregate complication rates also declined. At these hospitals, the differences between actual complication rates and severity adjusted complication rates were also reduced. At the third hospital, specific and aggregate complication rates remained the same or increased slightly. Differences between these rates and those of severity adjusted comparison population also remained the same or increased. Conclusions Results of the study suggested that, in one community health care system, the progress of reducing complications involved different experiences. At two hospitals with relatively higher rates at the beginning of the study, management by administrative and clinical staff outside quality assurance produced significant reductions in complication rates, while at a hospital with lower rates, management by quality assurance staff had little effect on reducing the rate of PPCs.

  19. Who Owns Child Abuse?

    Gerald Cradock

    2014-11-01

    Full Text Available Expectations of contemporary child protection apparatuses are strongly influenced by beliefs inherited from the nineteenth century child rescue movement. In particular, the belief that child abuse determination is obvious. However, this assumption fails to make a distinction between nineteenth century’s emphasis on impoverished environments and the twentieth century introduction of the pathological child abuser. Moreover, the proliferation of kinds of child abuse, and the need to distinguish child abusers from non-abusers, means knowledge is now spread across an array of disciplines and professions, which necessarily destabilizes the definition of child abuse. The increasing exposure of alternate care systems as potentially abusive has similarly destabilized the old common sense solution to neglected children—namely removal. Finally, as uncertainty increases, and definitions become more divergent, the question of what child abuse is, and what should be done about it, becomes increasingly politicized.

  1. Alcohol abuse and HIV infection have additive effects on frontal cortex function as measured by auditory evoked potential P3A latency.

    Fein, G; Biggins, C A; MacKay, S

    1995-02-01

    Both alcohol and human immunodeficiency virus (HIV) infection have been shown to produce central nervous system (CNS) morbidity in frontal brain regions. The degree to which the CNS morbidity in HIV infection, as it affects frontal cortex function, may be preferentially increased by alcohol abuse was examined using the auditory P3A evoked potential. The P3A indexes an orienting response, maximal over frontal cortex that occurs when novel nontarget stimuli are presented in the midst of a target detection paradigm. Four groups of subjects were compared: HIV+ alcohol abusers, HIV+ light/nondrinkers, HIV- alcohol abusers, and HIV- light/nondrinkers. The alcohol abuser and light/nondrinker HIV+ groups were matched on percent CD4 lymphocytes, insuring that the results reflected specific CNS effects and were not a result of differences between the groups in the degree of systemic immune suppression. Alcohol abuse and HIV infection had at least additive effects on P3A latency, consistent with alcohol abuse worsening the effect of HIV disease on frontal cortex function. Post-hoc analyses suggested that concomitant alcohol abuse results in the effects of HIV infection on P3A latency becoming manifest earlier in the HIV disease process. PMID:7727627

  3. Advocacy Interventions to Reduce or Eliminate Violence and Promote the Physical and Psychosocial Wellbeing of Women Who Experience Intimate Partner Abuse: A Systematic Review

    Rivas, C

    2016-01-01

    Full Text Available BACKGROUND Intimate partner abuse is common worldwide, damaging the short- and long-term physical, mental, and emotional health of survivors and children. Advocacy may contribute to reducing abuse, empowering women to improve their situation by providing informal counselling and support for safety planning and increasing access to different services. Advocacy may be a stand-alone service, accepting referrals from healthcare providers, or part of a multi-component (and possibly multi-agency intervention provided by service staff or others. OBJECTIVES To assess the effects of advocacy interventions within or outside healthcare settings in women who have experienced intimate partner abuse. SEARCH METHODS In April 2015, we searched CENTRAL, Ovid MEDLINE, EMBASE, and 10 other databases. We also searched WHO ICTRP, mRCT, and UK Clinical Research Network (UKCRN, and examined relevant websites and reference lists with forward citation tracking of included studies. For the original review we handsearched six key journals. We also contacted first authors of eligible papers and experts in the field. SELECTION CRITERIA Randomised or quasi-randomised controlled trials comparing advocacy interventions for women with experience of intimate partner abuse versus no intervention or usual care (if advocacy was minimal and fewer than 20% of women received it. DATA COLLECTION AND ANALYSIS Two review authors independently assessed risk of bias and undertook data extraction. We contacted authors for missing information needed to calculate statistics for the review and looked for adverse events. MAIN RESULTS We included 13 trials involving 2141 participants aged 15 to 65 years, frequently having low socioeconomic status. The studies were quite heterogeneous in terms of methodology, study processes and design, including with regard to the duration of follow-up (postintervention to three years, although this was not associated with differences in effect. The studies also

    Full Text Available Justin John Gandy, Ilze Laurens, Jacques Rene Snyman Department of Pharmacology, School of Medicine, Faculty of Health Sciences, University of Pretoria, Pretoria, Gauteng, South Africa Introduction: Abundant anecdotal evidence for products claiming to reduce veisalgia after alcohol overindulgence are available on the Internet and as many advertisements in journals. None of these claims are, however, substantiated by research. The aim of this research was to ascertain the validity of such claims for the substance Absorbatox™, a potentiated aluminosilicate (cation exchanger able to bind NH4+, histamine, and other positively charged ions by investigating the signs and symptoms, as well as blood or breath alcohol levels, in healthy volunteers. Methods: Blood or breath alcohol levels were measured in all volunteers in initial controlled experiments, and symptoms were scored on a diary card for gastrointestinal tract symptoms, as well as other symptoms such as headache and light sensitivity. Eighteen volunteers completed the initial blood alcohol study, which investigated the effect of Absorbatox™ on blood alcohol levels after fasting. The follow-up studies researched the effects of the symptoms and signs of alcohol overindulgence. The “night out” study was completed by ten volunteers in a typical controlled environment, which was followed by the real-life four-leg crossover study. In the crossover study, volunteers (number =25 completers had to fill matching diary cards to containers of two placebo and two active drugs after a night out where they themselves decided on the container (color coded to be used and the amount of alcohol to be consumed. Results: Absorbatox™ had no effect on blood alcohol levels, but it significantly reduced the symptoms and signs of veisalgia by approximately 40%–50%. Conclusion: This research indicates that Absorbatox™ does not have an effect on blood- or breath-alcohol levels. Furthermore, treatment with

    In this study, quantification of mRNA gene expression was examined as biomarkers to detect ractopamaine abuse and ractopamaine residues in cashmere goats. It was focused on the identification of potential gene expression biomarkers and describing the coreletionship between gene expression and residue level by 58 animals for 49 days. The results showed that administration periods and residue levels significantly influenced mRNA expressions of the β2-adrenergic receptor (β2AR), the enzymes PRKACB, ADCY3, ATP1A3, ATP2A3, PTH, and MYLK, and the immune factors IL-1β and TNF-α. Statistical analysis like principal components analysis (PCA), hierarchical cluster analysis (HCA), and discriminant analysis (DA) showed that these genes can serve as potential biomarkers for ractopamine in skeletal muscle and that they are also suitable for describing different residue levels separately.

    Islamic Republic of Iran has to invest 95 billion US$ for her new oil refineries to the year 2045. At present, the emission factors for CO(2), NO( x ) and SO(2) are 3.5, 4.2 and 119 times higher than British refineries, respectively. In order to have a sustainable development in Iranian oil refineries, the government has to set emission factors of European Community as her goal. At present CO(2) per Gross Domestic Production (GDP) in the country is about 2.7 kg CO(2) as 1995's USD value that should be reduced to 1.25 kg CO(2)/GDP in the year 2015. Total capital investment for such reduction is estimated at 346 million USD which is equal to 23 USD/ton of CO(2). It is evident that mitigation of funds set by Clean Development Mechanism (3 to 7 USD/tons of CO(2)) is well below the actual capital investment needs. Present survey shows that energy efficiency promotion potential in all nine Iranian oil refineries is about 165,677 MWh/year through utilization of more efficient pumps and compressors. Better management of boilers in all nine refineries will lead to a saving of 273 million m(3) of natural gas per year. PMID:18066676

    Uncoupling the protein-protein interaction between collapsin response mediator protein 2 (CRMP2) and N-type voltage-gated calcium channel (CaV2.2) with an allosteric CRMP2-derived peptide (CBD3) is antinociceptive in rodent models of inflammatory and neuropathic pain. We investigated the efficacy, duration of action, abuse potential, and neurobehavioral toxicity of an improved mutant CRMP2 peptide. A homopolyarginine (R9)-conjugated CBD3-A6K (R9-CBD3-A6K) peptide inhibited the CaV2.2-CRMP2 interaction in a concentration-dependent fashion and diminished surface expression of CaV2.2 and depolarization-evoked Ca influx in rat dorsal root ganglia neurons. In vitro studies demonstrated suppression of excitability of small-to-medium diameter dorsal root ganglion and inhibition of subtypes of voltage-gated Ca channels. Sprague-Dawley rats with tibial nerve injury had profound and long-lasting tactile allodynia and ongoing pain. Immediate administration of R9-CBD3-A6K produced enhanced dopamine release from the nucleus accumbens shell selectively in injured animals, consistent with relief of ongoing pain. R9-CBD3-A6K, when administered repeatedly into the central nervous system ventricles of naive rats, did not result in a positive conditioned place preference demonstrating a lack of abusive liability. Continuous subcutaneous infusion of R9-CBD3-A6K over a 24- to 72-hour period reversed tactile allodynia and ongoing pain, demonstrating a lack of tolerance over this time course. Importantly, continuous infusion of R9-CBD3-A6K did not affect motor activity, anxiety, depression, or memory and learning. Collectively, these results validate the potential therapeutic significance of targeting the CaV-CRMP2 axis for treatment of neuropathic pain. PMID:27537210

  8. Neurosteroid Binding Sites on the GABAA Receptor Complex as Novel Targets for Therapeutics to Reduce Alcohol Abuse and Dependence

    Mary W. Hulin

    2011-01-01

    Full Text Available Despite the prevalence of alcohol abuse and dependence in the US and Europe, there are only five approved pharmacotherapies for alcohol dependence. Moreover, these pharmacotherapeutic options have limited clinical utility. The purpose of this paper is to present pertinent literature suggesting that both alcohol and the neurosteroids interact at the GABAA receptor complex and that the neurosteroid sites on this receptor complex could serve as new targets for the development of novel therapeutics for alcohol abuse. This paper will also present data collected by our laboratory showing that one neurosteroid in particular, dehydroepiandrosterone (DHEA, decreases ethanol intake in rats under a variety of conditions. In the process, we will also mention relevant studies from the literature suggesting that both particular subtypes and subunits of the GABAA receptor play an important role in mediating the interaction of neurosteroids and ethanol.

  15. Potential options to reduce GHG emissions in Venezuela

    Pereira, N.; Bonduki, Y.; Perdomo, M.

    1996-12-31

    The Government of Venezuela ratified the United Nations Framework Convention on Climate Change (UNFCCC) in December, 1994. The Convention requires all parties to develop and publish national inventories of anthropogenic greenhouse gas emissions (GHG) as well as national plans to reduce or control emissions, taking into account their common but differentiated responsibilities and their specific national and regional development priorities, objectives, and circumstances. Within this context, the Ministry of Environment and Renewable Natural Resources and the Ministry of Energy and Mines developed the `Venezuelan Case-Study to Address Climate Change`. The study was initiated in October 1993, with the financial and technical assistance of the Government of United States, through the U.S. Country Studies Program (USCSP), and the Global Environment Facility (GEF), through the United Nations Environment Programme (UNEP).

  18. Synthesis and evaluation of inhaled [11C]butane and intravenously injected [11C]acetone as potential radiotracers for studying inhalant abuse

    The phenomenon of inhalant abuse is a growing problem in the US and many countries around the world. Yet, relatively little is known about the pharmacokinetic properties of inhalants that underlie their abuse potential. While the synthesis of 11C-labeled toluene, acetone and butane has been proposed in the literature, none of these compounds has been developed as radiotracers for PET studies. In the present report we extend our previous studies with [11C]toluene to include [11C]acetone and [11C]butane with the goal of comparing the pharmacokinetic profiles of these three volatile abused substances. Both [11C]toluene and [11C]acetone were administered intravenously and [11C]butane was administered via inhalation to anesthesized baboons. Rapid and efficient uptake of radiolabeled toluene and acetone into the brain was followed by fast clearance in the case of toluene and slower kinetics in the case of acetone. [11C]Butane was detected in the blood and brain following inhalation, but the levels of radioactivity in both tissues dropped to half of the maximal values over the period of less than a minute. To our knowledge, this is the first reported study of the in vivo brain pharmacokinetics of labeled acetone and butane in nonhuman primates. These data provide insight into the pharmacokinetic features possibly associated with the abuse liability of toluene, acetone and butane

  19. Intelligent use and potential abuse of hormone assays in animal production research

    Immunoassays provide sensitive and specific techniques to measure very low concentrations of hormones in biological fluids. Use of these procedures has provided comprehensive plasma profiles for most hormones and contributed to a better understanding or reproductive function. One future challenge for basic research is the development of new methods to monitor and quantitate target organ response rather than continuing to determine concentrations. In applied or production-oriented projects the difficulties and expenses associated with most hormone assays are usually not justified. One exception is sequential monitoring of plasma or milk progesterone concentrations in twice weekly or weekly samples which can be used to detect the occurrence of sexual maturity, the time of first postpartum ovulation, the true incidence of anoestrus, whether individual females have regular ovarian cycles, and as an early test for pregnancy. Past results indicate that most healthy, adequately fed dairy cows in temperate regions ovulate during the first three or four weeks postpartum. Under intensive management systems the major problem in reproductive management of dairy cattle is oestrus detection. In contrast, many beef cows have not ovulated by 60 days postpartum, so prolonged anoestrus is a serious problem in suckled cows. Very little is known about nutrition, disease or climatic stress effects or interactions on reproductive performance in tropical environments. Regular progesterone concentrations from individual cows, combined with condition scores, management evaluation and breeding plus health records should accurately define the current reproductive performance, potential and problems. Once the major factors limiting reproductive efficiency have been defined, research projects can concentrate on the development of practical solutions. Sequential progesterone assays can then be incorporated into experimental procedures to objectively determine ovarian response. (author)

  20. Circulating microRNA-122 as Potential Biomarker for Detection of Testosterone Abuse

    Salamin, Olivier; Jaggi, Laetitia; Baume, Norbert; Robinson, Neil; Saugy, Martial; Leuenberger, Nicolas

    2016-01-01

    MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression and thus influence many cellular and physiological processes. miRNAs are also present in cell-free body fluids such as plasma or serum, and these circulating miRNAs are very stable, sensitive, and specific biomarkers of pathophysiological states. In this study, we investigated whether circulating miRNAs could serve as biomarkers of exogenous testosterone administration. Misuse of testosterone as a performance-enhancing drug is thought to be widespread in sports. Detection of testosterone through the urinary steroid profile of the Athlete Biological Passport faces several obstacles, indicating that new biomarkers are required. To this end, we analyzed plasma miRNA levels by high-throughput quantitative real-time PCR. Plasma samples were obtained before and at several time points after transdermal and oral testosterone administration. Screening identified three potential candidate miRNAs that were altered by both routes of testosterone administration. Longitudinal monitoring of these candidates revealed that variation in two of them (miR-150 and miR-342), relative to the corresponding levels in control samples, was testosterone-independent. However, levels of the liver-specific miR-122 increased 3.5-fold 1 day after drug intake. Given that testosterone is metabolized by the liver, this observation suggests that miR-122 in cell-free fluids may be used as a sensitive biomarker of testosterone misuse via multiple dosing routes and could therefore be integrated into a blood-based multiparametric follow-up.

    Background Prescription drug sales may vary considerably across regions and over time. This study aimed to assess whether there is an association between mean drug sales and prevalence of excessive use in a range of psychotropic prescription drugs with an abuse potential, and if so, whether the variation in mean drug sales mostly reflects variation in the prevalence of excessive use or mostly reflects variation in non-excessive use. ...

    Describes the EARLY ALLIANCE interventions, an integrated set of four programs designed to promote competence and reduce risk for early-onset conduct disorder, substance abuse, and school failure. These interventions are evaluated as part of a prevention trial that begins at school entry and targets child functioning and socializing practices across multiple contexts (school, peer group, family) and multiple domains (affective, social, and achievement coping-competence). The paper presents the conceptual foundation of the four interventions, including a synopsis of the risk and protective factors associated with conduct disorder and related outcomes, and of the coping-competence model driving EARLY ALLIANCE. The developmental rationale, intended impact, and procedures are described for each intervention: a universally administered classroom program and indicated, peer, reading-mentoring, and family programs. Interventions are currently being tested in a prevention trial, which is briefly summarized. PMID:11324096

    Rhodococcal cocaine esterase (CocE) is an attractive potential treatment for both cocaine overdose and cocaine addiction. CocE directly degrades cocaine into inactive products, whereas traditional small-molecule approaches require blockade of the inhibitory action of cocaine on a diverse array of monoamine transporters and ion channels. The usefulness of wild-type (wt) cocaine esterase is hampered by its inactivation at 37 C. Herein, we characterize the most thermostable form of this enzyme to date, CocE-L169K/G173Q. In vitro kinetic analyses reveal that CocE-L169K/G173Q displays a half-life of 2.9 days at 37 C, which represents a 340-fold improvement over wt and is 15-fold greater than previously reported mutants. Crystallographic analyses of CocE-L169K/G173Q, determined at 1.6-{angstrom} resolution, suggest that stabilization involves enhanced domain-domain interactions involving van der Waals interactions and hydrogen bonding. In vivo rodent studies reveal that intravenous pretreatment with CocE-L169K/G173Q in mice provides protection from cocaine-induced lethality for longer time periods before cocaine administration than wt CocE. Furthermore, intravenous administration (pretreatment) of CocE-L169K/G173Q prevents self-administration of cocaine in a time-dependent manner. Termination of the in vivo effects of CoCE seems to be dependent on, but not proportional to, its clearance from plasma as its half-life is approximately 2.3 h and similar to that of wt CocE (2.2 h). Taken together these data suggest that CocE-L169K/G173Q possesses many of the properties of a biological therapeutic for treating cocaine abuse but requires additional development to improve its serum half-life.

    Gender differences in vulnerability for cocaine addiction have been reported. Though the mechanisms are not understood, here we hypothesize that gender differences in reactivity to conditioned-cues, which contributes to relapse, are involved. To test this we compared brain metabolism (using PET and {sup 18}FDG) between female (n = 10) and male (n = 16) active cocaine abusers when they watched a neutral video (nature scenes) versus a cocaine-cues video. Self-reports of craving increased with the cocaine-cue video but responses did not differ between genders. In contrast, changes in whole brain metabolism with cocaine-cues differed by gender (p<0.05); females significantly decreased metabolism (-8.6% {+-} 10) whereas males tended to increase it (+5.5% {+-} 18). SPM analysis (Cocaine-cues vs Neutral) in females revealed decreases in frontal, cingulate and parietal cortices, thalamus and midbrain (p<0.001) whereas males showed increases in right inferior frontal gyrus (BA 44/45) (only at p<0.005). The gender-cue interaction showed greater decrements with Cocaine-cues in females than males (p<0.001) in frontal (BA 8, 9, 10), anterior cingulate (BA 24, 32), posterior cingulate (BA 23, 31), inferior parietal (BA 40) and thalamus (dorsomedial nucleus). Females showed greater brain reactivity to cocaine-cues than males but no differences in craving, suggesting that there may be gender differences in response to cues that are not linked with craving but could affect subsequent drug use. Specifically deactivation of brain regions from 'control networks' (prefrontal, cingulate, inferior parietal, thalamus) in females could increase their vulnerability to relapse since it would interfere with executive function (cognitive inhibition). This highlights the importance of gender tailored interventions for cocaine addiction.

  6. Elder abuse

    1999-01-01

    Elder abuse takes many forms and occurs in a variety of settings; it is both under-recognised and under-reported. Despite a lack of statutory guidelines or legislation, effective management is possible. More could be done to recognise abuse, and healthcare workers need to be vigilant, paying attention to both the circumstances in which abuse occurs and its warning signs.

  7. Uncovering sexual abuse: evaluation of the effectiveness of The Victims of Violence and Abuse Prevention Programme.

    Donohoe, J

    2010-02-01

    Discusses factors inhibiting open talk around a client's history of abuse including gender, age and diagnosis. * Evaluates the helpfulness of a training course designed to reduce and overcome these factors. * Aim of the evaluation is to help replicate the training nationally, following the positive impact found. Abstract Despite the high prevalence of sexual abuse among users of mental health services, it appears that mental health professionals are frequently unaware of clients' abuse histories. In order to address this, a Mental Health Trusts Collaboration Project of nine trusts was formed, which piloted delivering the Department of Health's Victims of Violence & Abuse Prevention Programme one-day education and training course regarding enquiring about histories of sexual abuse to various mental health practitioners. This hoped to educate practitioners in factors associated with victims and offenders, improve confidence and competence in asking about client's history of abuse and to increase awareness of the importance of asking. The purpose of this paper is to describe the impact of this course on mental health professionals' practice and attitudes in one of these nine trusts. It was found that since the delivery of the course, 44% (n= x) of professionals had been asking about abuse in 75-100% of cases. Gender, age and diagnosis of both the service users and the practitioners were all identified as factors potentially affecting practitioners' willingness to ask about abuse. Most importantly, 93% (n= x) of participants were found to feel they have the skills and knowledge to enquire about abuse and respond to disclosure in the appropriate way and 77% (n= x) of participants felt that this training had changed their clinical practice. The aim of this evaluation is to prove the effectiveness of the Department of Health's education and training course, which will help towards replicating the project nationally. PMID:20100302

  8. Child abuse

    Child abuse is common in most, if not all, Western nations; it probably occurs worldwide. It may be a major factor in the increase in violence throughout much of the world. Radiologists who treat children should think of the possibilitys of abuse whenever they diagnose a fracture, intracranial bleed, ar visceral injury, especially when the history is not compatible with their findings. Metaphyseal 'corner' fractures in infants usually are caused by abuse. Less than 20% of abused children, however, present injuries that can be recognized by radiologic techniques. Consequently normal roentgenograms, nuclear medicine scans, ultrasound studies, and computed tomograms do not exclude child abuse. (orig.)

    ALO-02 is an abuse-deterrent formulation consisting of capsules filled with pellets of extended-release oxycodone surrounding sequestered naltrexone. This randomized, double-blind, placebo-/active-controlled, 4-way crossover study examined the abuse potential of crushed ALO-02 administered intranasally to healthy, nondependent, recreational opioid users. Following drug discrimination and naloxone challenge, eligible participants (n = 32) entered a 4-way crossover treatment phase: crushed single dose of 1 of 2 placebos, ALO-02 30 mg/3.6 mg (oxycodone/naltrexone) or oxycodone immediate-release (IR) 30 mg. Primary end points were Drug Liking and High, measured on visual analog scales (VAS) summarized as maximum effect (Emax ) and effect occurring over 2 hours postdose (AUE0-2  h ). Crushed ALO-02 resulted in significantly lower scores versus oxycodone IR on Drug Liking (Emax , 60.5 vs 92.8; AUE0-2  h , 105.4 vs 160.0, respectively) and High (Emax , 25.2 vs 86.9; AUE0-2  h , 27.1 vs 136.4, respectively; n = 28; P < .0001). Adverse events occurred most frequently with oxycodone IR, followed by ALO-02, then placebo, and were considered mild and consistent with opioid therapy. Crushed ALO-02 administered intranasally to nondependent recreational opioid users resulted in significantly lower scores on Drug Liking/High VAS and other positive subjective measures versus crushed oxycodone IR, suggesting less abuse potential. Demonstration of actual abuse deterrence in the real world requires further research. PMID:26011742

  14. Reducing capacities and redox potentials of humic substances extracted from sewage sludge.

    Yang, Zhen; Du, Mengchan; Jiang, Jie

    2016-02-01

    Humic substances (HS) are redox active organic materials that can be extracted from sewage sludge generated in wastewater treatment processes. Due to the poor understanding of reducing capacity, redox potentials and redox active functional groups of HS in sewage sludge, the potential contribution of sludge HS in transformation of wastewater contaminants is unclear. In the present study, the number of electrons donated or accepted by sewage sludge HS were quantified before and after reduction by iron compounds that possess different redox potentials and defined as the reducing capacity of the sewage sludge. In contrast to previous studies of soil and commercial humic acids (HA), reduced sludge HA showed a lower reducing capacity than that of native HA, which implies formation of semiquinone radicals since the semiquinone radical/hydroquinone pair has a much higher redox potential than the quinone/hydroquinone pair. It is novel that reducing capacities of sludge HA were determined in the redox potential range from -314 to 430 mV. The formation of semiquinone radicals formed during the reduction of quinone moieties in sludge HA is shown by three-dimensional excitation/emission matrix fluorescence spectroscopies information, increasing fluorescence intensities and blue-shifting of the excitation/emission peak of reduced sludge HA. Knowledge of sludge HS redox potentials and corresponding reducing capacities makes it possible to predict the transformation of redox active pollutants and facilitate manipulation and optimization of sludge loading wastewater treatment processes.

  15. Redundant states, reduced potentials, and extra nodes in the radial wave function

    First-principle scattering calculations which include antisymmetrization of a projectile with respect to identical particles in the target result in a nonsymmetric nonlocal effective potential. Such a potential can lead to redundant states in the scattering wave function. In this case the potential is required to satisfy a consistency condition. We discuss this condition and the manner in which it can be imposed. We also discuss the replacement of this potential by a reduced symmetric nonlocal effective potential which does not produce redundant states. This reduced potential generates a scattering wave function orthogonal to the redundant states. If the original equation has one redundant state, the phase shift at zero energy is π, resulting in an extra node in the zero-energy wave function. The reduced effective potential must retain this extra node. This characteristic of the reduced effective potential is illustrated with an example. We show that the extra node produced by the potential in the example comes either from a spurious state or a bound state of that potential

    This work illustrates the potential of hybrid quadrupole-time-of-flight mass spectrometry (QTOF MS) coupled to ultrahigh pressure liquid chromatography (UHPLC) to investigate the presence of drugs of abuse in wastewater. After solid-phase extraction with Oasis MCX cartridges, seventy-six illicit drugs, prescription drugs with potential for abuse, and metabolites were investigated in the samples by TOF MS using electrospray interface under positive ionization mode, with MS data acquired over an m/z range of 50-1000 Da. For 11 compounds, reference standards were available, and experimental data (e.g., retention time and fragmentation data) could be obtained, facilitating a more confident identification. The use of a QTOF instrument enabled the simultaneous application of two acquisition functions with different collision energies: a low energy (LE) function, where none or poor fragmentation took place, and a high energy (HE) function, where fragmentation in the collision cell was promoted. This approach, known as MS{sup E}, enabled the simultaneous acquisition of full-spectrum accurate mass data of both protonated molecules and fragment ions in a single injection, providing relevant information that facilitates the rapid detection and reliable identification of these emerging contaminants in the sample matrices analyzed. In addition, isomeric compounds, like the opiates, morphine and norcodeine, could be discriminated by their specific fragments observed in HE TOF MS spectra, without the need of reference standards. UHPLC-QTOF MS was proven to be a powerful and efficient technique for rapid wide-scope screening and identification of many relevant drugs in complex matrices, such as influent and effluent urban wastewater.

    Deforestation is the second largest anthropogenic source of carbon dioxide emissions and options for its reduction are integral to climate policy. In addition to providing potentially low cost and near-term options for reducing global carbon emissions, reducing deforestation also could support biodiversity conservation. However, current understanding of the potential benefits to biodiversity from forest carbon offset programs is limited. We compile spatial data on global forest carbon, biodiv...

  19. Combining a reactive potential with a harmonic approximation for molecular dynamics simulation of failure: construction of a reduced potential

    Molecular dynamics is a simulation technique that can be used to study failure in solids, provided the inter-atomic potential energy is able to account for the complex mechanisms at failure. Reactive potentials fitted on ab initio results or on experimental values have the ability to adapt to any complex atomic arrangement and, therefore, are suited to simulate failure. But the complexity of these potentials, together with the size of the systems considered, make simulations computationally expensive. In order to improve the efficiency of numerical simulations, simpler harmonic potentials can be used instead of complex reactive potentials in the regions where the system is close to its ground state and a harmonic approximation reasonably fits the actual reactive potential. However the validity and precision of such an approach has not been investigated in detail yet. We present here a methodology for constructing a reduced potential and combining it with the reactive one. We also report some important features of crack propagation that may be affected by the coupling of reactive and reduced potentials. As an illustrative case, we model a crystalline two-dimensional material (graphene) with a reactive empirical bond-order potential (REBO) or with harmonic potentials made of bond and angle springs that are designed to reproduce the second order approximation of REBO in the ground state. We analyze the consistency of this approximation by comparing the mechanical behavior and the phonon spectra of systems modeled with these potentials. These tests reveal when the anharmonicity effects appear. As anharmonic effects originate from strain, stress or temperature, the latter quantities are the basis for establishing coupling criteria for on the fly substitution in large simulations

  1. Early maladaptive schemas of substance abusers and their intimate partners.

    Shorey, Ryan C; Anderson, Scott; Stuart, Gregory L

    2013-01-01

    The influence of intimate partners in the recovery of substance abuse has been increasingly recognized in the professional literature. Couples-based substance abuse treatment has demonstrated effectiveness in reducing substance abuse and increasing healthy couple functioning. Recently, research has begun to investigate enduring cognitive beliefs that may impact substance abusers and their intimate partners, which could advance our understanding of factors that may impact couple's functioning. The current study examined the early maladaptive schemas and substance use of a sample of adult substance abusers who have sought residential substance abuse treatment and their intimate partners (N = 102). Results demonstrated that the early maladaptive schemas of patients and their intimate partners may be interrelated and that patients scored significantly higher than their partners on 13 of the 18 early maladaptive schemas. Substance use was only associated with a few early maladaptive schemas. These findings highlight the potential importance of assessing early maladaptive schemas in couples where one partner has a substance abuse problem. Implications of these findings for future research are discussed. PMID:24175492

    We describe a practical algorithm for constructing the Kohn–Sham exchange-correlation potential corresponding to a given second-order reduced density matrix. Unlike conventional Kohn–Sham inversion methods in which such potentials are extracted from ground-state electron densities, the proposed technique delivers unambiguous results in finite basis sets. The approach can also be used to separate approximately the exchange and correlation potentials for a many-electron system for which the reduced density matrix is known. The algorithm is implemented for configuration-interaction wave functions and its performance is illustrated with numerical examples.

    There is a strong argument that the formalisation of informal land markets can reduce urban poverty. In this view, the potential to reduce poverty lies in the ability of the state to introduce appropriate forms of formality and the intrinsic abilities of markets to generate wealth. Pointing to evidence that the results of formalisation initiatives have been less impressive in practice, I argue that one of the reasons is a failure to analyse informal land markets in their own terms.

  11. The Potential of Various Living Tissues for Monitoring Clenbuterol Abuse in Food-Producing Chinese Simmental Beef Cattle.

    Li, Lijun; Tang, Chaohua; Zhang, Junmin; Zhao, Qingyu; Zhang, Kai

    2016-01-01

    We aimed to evaluate whether living tissues such as urine, plasma and hair were suitable for monitoring clenbuterol (CL) abuse after its subchronic administration of a growth-promoting dose to the Chinese Simmental beef cattle. Eight male, white and red pied Chinese Simmental beef cattle were involved in the experiment, and the CL dose was 16 µg/kg BW/day. Liquid chromatography tandem mass spectrometry (LC-MS-MS) was used to determine CL residues in different tissues, and the addition of D9-clenbuterol internal standard was applied to increase determination accuracy. The recovery of plasma, urine, hair and in vivo tissues was 88.5-114.2, 83.9-114.3, 88.6-116.9 and 85.3-121.7%, respectively. The results showed that CL residue concentrations in the plasma, on Days 14 after withdrawal and later, were lower than the limit of detection (LOD) (0.06 ng/mL) and CL residue in urine was lower than LOD (0.16 ng/mL) 42 days after treatment. CL significantly accumulated in the white and red hair and maintained more than 7.19 ± 2.19 pg/mg within the early withdrawal period of 70 days. A large number of CL were determined in all tested biological tissues, in which residues were higher than the maximum residue limits (MRLs) after dietary administration of CL for 21 days and pre-slaughter withdrawal period of ∼6 h. A particular concern is the slow depletion of residues of CL in some tissues like gluteus and liver still exceeding theirs MRLs, respectively, on Days 14 or 28 days after withdrawal. Our study indicated that plasma and urine could be available for monitoring CL abuse only within a short period of time. However, hair (including light-pigmented) as a target matrix can be selected to perform the long-period monitor of CL. PMID:26487642

    This paper reports that this study used SPECT to examine patients who have abused drugs to determine whether SPECT could identify abnormalities and whether these findings have clinical importance. Fifteen patients with a history of substance abuse (eight with cocaine, six with amphetamine, and one with organic solvent) underwent SPECT performed with a triple-headed camera and Tc-99m HMPAO both early for blood flow and later for functional information. These images were then processed into a 3D videotaped display used in group therapy. All 15 patients had multiple areas of decreased tracer uptake peppered throughout the cortex but mainly affecting the parietal lobes, expect for the organic solvent abuser who had a large parietal defect. The videotapes were subjectively described by a therapist as an exceptional tool that countered patient denial of physical damage from substance abuse.

  17. The Potential for Abandoned Paddy Fields to Reduce Pollution Loads from Households in Suburban Tokyo

    Makoto Yokohari

    2010-09-01

    Full Text Available Similar to other Asian nations, suburban areas in Japan are characterized by dense intermixtures of residential areas and farmlands. These hybrid rural/urban areas are evaluated negatively in modern planning frameworks. However, mixed rural/urban landscapes may prove advantageous when attempting to reconstruct sustainable wastewater treatment systems. This research examines the potential for abandoned paddy fields to reduce nitrogen (T-N and phosphorous (T-P loads, an increasingly problematic source of eutrophication in many closed water areas, from households in suburban areas. Our results indicate that abandoned paddy fields remaining in mixed urban/rural areas have significant potential to reduce both nitrogen and phosphorous loads. Accordingly, we suggest that abandoned paddy fields can play an important role in reducing pollution loads in mixed urban/rural areas.

  18. Neighborhoods, Schools and Obesity: The Potential for Place-Based Approaches to Reduce Childhood Obesity.

    Brian Elbel

    Full Text Available A common policy approach to reducing childhood obesity aims to shape the environment in which children spend most of their time: neighborhoods and schools. This paper uses richly detailed data on the body mass index (BMI of all New York City public school students in grades K-8 to assess the potential for place-based approaches to reduce child obesity. We document variation in the prevalence of obesity across NYC public schools and census tracts, and then estimate the extent to which this variation can be explained by differences in individual-level predictors (such as race and household income. Both unadjusted and adjusted variability across neighborhoods and schools suggest place-based policies have the potential to meaningfully reduce child obesity, but under most realistic scenarios the improvement would be modest.

  20. Characterization of bromate-reducing bacterial isolates and their potential for drinking water treatment.

    Davidson, Andrew N; Chee-Sanford, Joanne; Lai, Hoi Yi Mandy; Ho, Chi-hua; Klenzendorf, J Brandon; Kirisits, Mary Jo

    2011-11-15

    The objective of the current study was to isolate and characterize several bromate-reducing bacteria and to examine their potential for bioaugmentation to a drinking water treatment process. Fifteen bromate-reducing bacteria were isolated from three sources. According to 16S rRNA gene sequencing, the bromate-reducing bacteria are phylogenetically diverse, representing the Actinobacteria, Bacteroidetes, Firmicutes, and α-, β-, and γ-Proteobacteria. The broad diversity of bromate-reducing bacteria suggests the widespread capability for microbial bromate reduction. While the cometabolism of bromate via nitrate reductase and (per)chlorate reductase has been postulated, five of our bromate-reducing isolates were unable to reduce nitrate or perchlorate. This suggests that a bromate-specific reduction pathway might exist in some microorganisms. Bioaugmentation of activated carbon filters with eight of the bromate-reducing isolates did not significantly decrease start-up time or increase bromate removal as compared to control filters. To optimize bromate reduction in a biological drinking water treatment process, the predominant mechanism of bromate reduction (i.e., cometabolic or respiratory) needs to be assessed so that appropriate measures can be taken to improve bromate removal.

  1. Malaria transmission potential could be reduced with current and future climate change

    Several studies suggest the potential for climate change to increase malaria incidence in cooler, marginal transmission environments. However, the effect of increasing temperature in warmer regions where conditions currently support endemic transmission has received less attention. We investigate how increases in temperature from optimal conditions (27 °C to 30 °C and 33 °C) interact with realistic diurnal temperature ranges (DTR: ± 0 °C, 3 °C, and 4.5 °C) to affect the ability of key vector species from Africa and Asia (Anopheles gambiae and An. stephensi) to transmit the human malaria parasite, Plasmodium falciparum. The effects of increasing temperature and DTR on parasite prevalence, parasite intensity, and mosquito mortality decreased overall vectorial capacity for both mosquito species. Increases of 3 °C from 27 °C reduced vectorial capacity by 51–89% depending on species and DTR, with increases in DTR alone potentially halving transmission. At 33 °C, transmission potential was further reduced for An. stephensi and blocked completely in An. gambiae. These results suggest that small shifts in temperature could play a substantial role in malaria transmission dynamics, yet few empirical or modeling studies consider such effects. They further suggest that rather than increase risk, current and future warming could reduce transmission potential in existing high transmission settings. PMID:27324146

  4. Charge density distributions derived from smoothed electrostatic potential functions: design of protein reduced point charge models.

    Leherte, Laurence; Vercauteren, Daniel P

    2011-10-01

    To generate reduced point charge models of proteins, we developed an original approach to hierarchically locate extrema in charge density distribution functions built from the Poisson equation applied to smoothed molecular electrostatic potential (MEP) functions. A charge fitting program was used to assign charge values to the so-obtained reduced representations. In continuation to a previous work, the Amber99 force field was selected. To easily generate reduced point charge models for protein structures, a library of amino acid templates was designed. Applications to four small peptides, a set of 53 protein structures, and four KcsA ion channel models, are presented. Electrostatic potential and solvation free energy values generated by the reduced models are compared with the corresponding values obtained using the original set of atomic charges. Results are in closer agreement with the original all-atom electrostatic properties than those obtained with a previous reduced model that was directly built from the smoothed MEP functions [Leherte and Vercauteren in J Chem Theory Comput 5:3279-3298, 2009].

  5. A Dipole Polarizable Potential for Reduced and Doped CeO$_2$ from First-Principles

    Burbano, Mario; Yildiz, Bilge; Tuller, Harry L; Norberg, Stefan T; Hull, Stephen; Madden, Paul A; Watson, Graeme W

    2011-01-01

    In this paper we present the parameterization of a new interionic potential for stoichiometric, reduced and doped CeO$_2$. We use a dipole-polarizable potential (DIPPIM) and optimize its parameters by fitting them to a series of DFT calculations. The resulting potential was tested by calculating a series of fundamental properties for CeO$_2$ and by comparing them to experimental values. The agreement for all the calculated properties (thermal and chemical expansion coefficients, lattice parameters, oxygen migration energies, local crystalline structure and elastic constants) is within 10-15% of the experimental one, an accuracy comparable to that of ab initio calculations. This result suggests the use of this new potential for reliably predicting atomic-scale properties of CeO$_2$ in problems where ab initio calculations are not feasible due to their size-limitations.

  6. Understanding abuse of women with physical disabilities: an overview of the abuse pathways model.

    Hassouneh-Phillips, Dena

    2005-01-01

    The purpose of this article is to provide an overview of an empirically based theoretical model of abuse of women with physical disabilities. The Abuse Pathways model was developed from a critical disability life history research study conducted with 37 women who had simultaneously experienced abuse and physical disability. The model begins to address the complexity of abuse of women with physical disabilities by identifying the interactive components of the phenomenon. These components include (1) the social context of disability; (2) women's abuse trajectories; and (3) vulnerability factors for abuse. The article concludes by discussing potential applications and limitations of the model. PMID:15718940

  8. What is the potential for reducing national greenhouse gas emissions from crop and livestock production systems?

    Audsley, Eric; Wilkinson, Mike

    2014-01-01

    Agriculture has a devolved commitment to reduce national emissions of greenhouse gases (GHG). Using a systems model-based life-cycle analysis we explored the potential for reducing GHG in systems used to produce twelve crop and seven livestock commodities. With a functional unit of kg of product, differences in GHG between crops reflect differences in yield. Metabolisable energy (ME) or crude protein (CP) could be used, but deriving an economic value of GB£8.6/GJ ME and GB£0.62/kg CP, leads t...

  9. A Prospective Study of the Potential Moderating Role of Social Support in Preventing Marginalization Among Individuals Exposed to Bullying and Abuse in Junior High School

    Negative physical and psychological long-term consequences of abuse and bullying are well documented. It is reasonable to assume that abuse and bullying early in life also may have an impact on the ability to work and stay economically independent later in life, but such prospective studies are lacking. This study investigates the consequences of exposure to abuse and bullying in junior high school, as measured by receiving long-term social welfare benefits in young adulthood. In addition, it...

  10. The relationship between child abuse and handicapping conditions.

    Mullins, J B

    1986-04-01

    This article discusses the relationship of child abuse, including neglect and sexual abuse, to the presence of handicapping conditions, both physical and psychological. Child abuse can cause physical and psychological disabilities in children who otherwise would have been normal. Studies show that children who are handicapped, or otherwise perceived as different by potentially abusive parents, are at high risk for abuse. Evidence also indicates that the handicaps of some children who were diagnosed originally as disabled are exacerbated by abuse. While cause and effect are not easily determined in specific cases, researchers agree that a pervasive relationship exists between handicapping conditions and abuse. Abused children are overrepresented in special education classes and handicapped children are overrepresented in the abused population. Many abused children become abusers as adults. Several suggestions concerning the problem are offered for school personnel. PMID:2937963

  11. A method for computing the inter-residue interaction potentials for reduced amino acid alphabet

    Abhinav Luthra; Anupam Nath Jha; G K Ananthasuresh; Saraswathi Vishveswara

    2007-08-01

    Inter-residue potentials are extensively used in the design and evaluation of protein structures. However, dealing with all (20×20) interactions becomes computationally difficult in extensive investigations. Hence, it is desirable to reduce the alphabet of 20 amino acids to a smaller number. Currently, several methods of reducing the residue types exist; however a critical assessment of these methods is not available. Towards this goal, here we review and evaluate different methods by comparing with the complete (20×20) matrix of Miyazawa-Jernigan potential, including a method of grouping adopted by us, based on multi dimensional scaling (MDS). The second goal of this paper is the computation of inter-residue interaction energies for the reduced amino acid alphabet, which has not been explicitly addressed in the literature until now. By using a least squares technique, we present a systematic method of obtaining the interaction energy values for any type of grouping scheme that reduces the amino acid alphabet. This can be valuable in designing the protein structures.

  12. Targeting the treatment of drug abuse with molecular imaging

    Although imaging studies in and of themselves have significant contributions to the study of human behavior, imaging in drug abuse has a much broader agenda. Drugs of abuse bind to molecules in specific parts of the brain in order to produce their effects. Positron emission tomography (PET) provides a unique opportunity to track this process, capturing the kinetics with which an abused compound is transported to its site of action. The specific examples discussed here were chosen to illustrate how PET can be used to map the regional distribution and kinetics of compounds that may or may not have abuse liability. We also discussed some morphological and functional changes associated with drug abuse and different stages of recovery following abstinence. PET measurements of functional changes in the brain have also led to the development of several treatment strategies, one of which is discussed in detail here. Information such as this becomes more than a matter of academic interest. Such knowledge can provide the bases for anticipating which compounds may be abused and which may not. It can also be used to identify biological markers or changes in brain function that are associated with progression from drug use to drug abuse and also to stage the recovery process. This new knowledge can guide legislative initiatives on the optimal duration of mandatory treatment stays, promoting long-lasting abstinence and greatly reducing the societal burden of drug abuse. Imaging can also give some insights into potential pharmacotherapeutic targets to manage the reinforcing effects of addictive compounds, as well as into protective strategies to minimize their toxic consequences

  13. Open Circuit Potential Study of Stainless Steel in Environment Containing Marine Sulphate-Reducing Bacteria

    The corrosion potential of AISI 304 stainless steel coupons influenced by sulphate-reducing bacteria (SRB) has been studied. Pure colony of SRB was isolated from the Malaysia Marine and Heavy Engineering, Pasir Gudang, Johor. Open circuit potential measurements were carried out in variable types of culturing solutions with SRB1, SRB2, combination of SRB1 and SRB2 and without SRBs inoculated. Results showed that the corrosion potential, Eoc increased in the presence of SRBs (in pure and mixed culture) compared to that of control. EDS analysis showed the strong peak of sulphur in coupon containing SRB cultures compared to the control. ESEM data showed that the high density cell of SRBs were associated with corroding sections of surface steel comparing with non-corroding sections for coupons immersed in VMNI medium containing SRBs.

  14. Potential nanotechnology applications for reducing freshwater consumption at coal fired power plants : an early view.

    Elcock, D. (Environmental Science Division)

    2010-09-17

    This report was funded by the U.S. Department of Energy's (DOE's) National Energy Technology Laboratory (NETL) Existing Plants Research Program, which has an energy-water research effort that focuses on water use at power plants. This study complements the overall research effort of the Existing Plants Research Program by evaluating water issues that could impact power plants. A growing challenge to the economic production of electricity from coal-fired power plants is the demand for freshwater, particularly in light of the projected trends for increasing demands and decreasing supplies of freshwater. Nanotechnology uses the unique chemical, physical, and biological properties that are associated with materials at the nanoscale to create and use materials, devices, and systems with new functions and properties. It is possible that nanotechnology may open the door to a variety of potentially interesting ways to reduce freshwater consumption at power plants. This report provides an overview of how applications of nanotechnology could potentially help reduce freshwater use at coal-fired power plants. It was developed by (1) identifying areas within a coal-fired power plant's operations where freshwater use occurs and could possibly be reduced, (2) conducting a literature review to identify potential applications of nanotechnology for facilitating such reductions, and (3) collecting additional information on potential applications from researchers and companies to clarify or expand on information obtained from the literature. Opportunities, areas, and processes for reducing freshwater use in coal-fired power plants considered in this report include the use of nontraditional waters in process and cooling water systems, carbon capture alternatives, more efficient processes for removing sulfur dioxide and nitrogen oxides, coolants that have higher thermal conductivities than water alone, energy storage options, and a variety of plant inefficiencies, which

  15. SUBSTANCE-ABUSING PREGNANT WOMEN: PRENATAL INTERVENTION USING ULTRASOUND CONSULTATION AND MENTALIZATION TO ENHANCE THE MOTHER-CHILD RELATIONSHIP AND REDUCE SUBSTANCE USE.

    Pajulo, Helena; Pajulo, Marjukka; Jussila, Heidi; Ekholm, Eeva

    2016-07-01

    Substance-abusing pregnant and parenting women are considered one of the most challenging, but important, target groups for developing early parenting interventions. Some valuable efforts to develop such interventions have been made in the organizational sector in Finland. However, there is a great need for new ways of work that would simultaneously concentrate in substance-abuse treatment and enhance parenting in public healthcare settings. The present article describes the background, content, and protocol of a new prenatal intervention developed for substance-abusing pregnant women in a hospital setting in public healthcare. The intervention includes two new elements and pathways aimed to enhance the mothers' curiosity toward her developing child and provide motivation to stay abstinent from substance use. The pathways are interactive ultrasound consultation and a new pregnancy diary, both using a parental mentalization focus. The intervention elements, experiences from running the intervention, evaluation protocol, and general characteristics of the study sample gained (n = 90) are described and discussed. Two case vignettes from the study sample are presented, and the applicability of this prenatal work with other groups and settings is considered. PMID:27341555

  17. Potential biodiversity benefits from international programs to reduce carbon emissions from deforestation.

    Siikamäki, Juha; Newbold, Stephen C

    2012-01-01

    Deforestation is the second largest anthropogenic source of carbon dioxide emissions and options for its reduction are integral to climate policy. In addition to providing potentially low cost and near-term options for reducing global carbon emissions, reducing deforestation also could support biodiversity conservation. However, current understanding of the potential benefits to biodiversity from forest carbon offset programs is limited. We compile spatial data on global forest carbon, biodiversity, deforestation rates, and the opportunity cost of land to examine biodiversity conservation benefits from an international program to reduce carbon emissions from deforestation. Our results indicate limited geographic overlap between the least-cost areas for retaining forest carbon and protecting biodiversity. Therefore, carbon-focused policies will likely generate substantially lower benefits to biodiversity than a more biodiversity-focused policy could achieve. These results highlight the need to systematically consider co-benefits, such as biodiversity in the design and implementation of forest conservation programs to support international climate policy.

  18. Diversity and Characterization of Potential H2-Dependent Fe(Ⅲ)-Reducing Bacteria in Paddy Soils

    LI Hui-Juan; PENG Jing-Jing; LI Hong-Bo

    2012-01-01

    Microbial ferric iron reduction,with organic carbon or hydrogen as the electron donor,is one of the most important biogeochemical processes in anoxic paddy soils; however,the diversity and community structure of hydrogen-dependent dissimilatory iron-reducers remain unknown.Potential H2-dependent Fe(Ⅲ)-reducing bacteria in paddy soils were explored using enrichment cultures with ferrihydrite or goethite as the electron acceptor and hydrogen as the electron donor.Terminal restriction fragment length polymorphism (T-RFLP) analysis and cloning/sequencing were conducted to reveal bacterial comnunity structure.Results showed that Geobacter and Clostridium were the dominant bacteria in the enrichment cultures.Fe(Ⅲ) oxide mineral phases showed a strong effect on the community structure; Geobacter and Clostridium were dominant in the ferrihydrite treatment,while Clostridium spp were dominant in the goethite treatment.These suggested that H2-dependent Fe(Ⅲ)-reducing bacteria might be widely distributed in paddy soils and that besides Geobacter,Clostridium spp.might also be an important group of H2-dependent Fe(Ⅲ)-reducing microorganisms.

  20. Dimensionally reduced expression for the QCD fermion determinant at finite temperature and chemical potential

    A dimensionally reduced expression for the QCD fermion determinant at finite temperature and chemical potential is derived which sheds light on the determinant's dependence on these quantities. This is done via a partial zeta regularization, formally applying a general formula for the zeta determinant of a differential operator in one variable with operator-valued coefficients. The resulting expression generalizes the known one for the free fermion determinant, obtained via Matsubara frequency summation, to the case of a general background gauge field; moreover there is no undetermined overall factor. Rigorous versions of the result are obtained in a continuous time-lattice space setting. The determinant expression reduces to a remarkably simple form in the low temperature limit. A program for using this to obtain insight into the QCD phase transition at zero temperature and nonzero density is outlined

  2. New drugs of abuse.

    Rech, Megan A; Donahey, Elisabeth; Cappiello Dziedzic, Jacqueline M; Oh, Laura; Greenhalgh, Elizabeth

    2015-02-01

    Drug abuse is a common problem and growing concern in the United States, and over the past decade, novel or atypical drugs have emerged and have become increasingly popular. Recognition and treatment of new drugs of abuse pose many challenges for health care providers due to lack of quantitative reporting and routine surveillance, and the difficulty of detection in routine blood and urine analyses. Furthermore, street manufacturers are able to rapidly adapt and develop new synthetic isolates of older drugs as soon as law enforcement agencies render them illegal. In this article, we describe the clinical and adverse effects and purported pharmacology of several new classes of drugs of abuse including synthetic cannabinoids, synthetic cathinones, salvia, desomorphine, and kratom. Because many of these substances can have severe or life-threatening adverse effects, knowledge of general toxicology is key in recognizing acute intoxication and overdose; however, typical toxidromes (e.g., cholinergic, sympathomimetic, opioid, etc.) are not precipitated by many of these agents. Medical management of patients who abuse or overdose on these drugs largely consists of supportive care, although naloxone may be used as an antidote for desomorphine overdose. Symptoms of aggression and psychosis may be treated with sedation (benzodiazepines, propofol) and antipsychotics (haloperidol or atypical agents such as quetiapine or ziprasidone). Other facets of management to consider include treatment for withdrawal or addiction, nutrition support, and potential for transmission of infectious diseases. PMID:25471045

  3. Reduced habituation of auditory evoked potentials indicate cortical hyper-excitability in Fragile X Syndrome.

    Ethridge, L E; White, S P; Mosconi, M W; Wang, J; Byerly, M J; Sweeney, J A

    2016-01-01

    Sensory hypersensitivities are common, clinically distressing features of Fragile X Syndrome (FXS). Preclinical evidence suggests this abnormality may result from synaptic hyper-excitability in sensory systems. This model predicts reduced sensory habituation to repeated stimulus presentation. Fourteen adolescents and adults with FXS and 15 age-matched controls participated in a modified auditory gating task using trains of 4 identical tones during dense array electroencephalography (EEG). Event-related potential and single trial time-frequency analyses revealed decreased habituation of the N1 event-related potential response in FXS, and increased gamma power coupled with decreases in gamma phase-locking during the early-stimulus registration period. EEG abnormalities in FXS were associated with parent reports of heightened sensory sensitivities and social communication deficits. Reduced habituation and altered gamma power and phase-locking to auditory cues demonstrated here in FXS patients parallels preclinical findings with Fmr1 KO mice. Thus, the EEG abnormalities seen in FXS patients support the model of neocortical hyper-excitability in FXS, and may provide useful translational biomarkers for evaluating novel treatment strategies targeting its neural substrate.

  6. Potential of tropical plants to exert defaunating effects on the rumen and to reduce methane production

    This paper summarises the principal results obtained in Cuba concerning the potential of different tropical plants to exert defaunating effects in the rumen and to reduce methane (CH4) production. The plants studied were Sapindus saponaria, Morus alba, Trichanthera gigantea, Tithonia diversifolia, Gliricidia sepium Leucaena leucocephala, Stizolobium aterrimun and Arachis pintoi. Grasses used as forage in the assays to obtain grass:foliage mixtures were Pennisetum purpureum Cuba CT-115 or Star grass (Cynodon nlemfuensis). The experiments were conducted using an in vitro system. Gases produced in the fermentation process were collected at intervals of 4, 8, 12 and 24 h and CH4 production was determined by gas chromatography. Phytochemical analyses indicated the presence of tannins, saponins and others secondary compounds. Enterolobium and Leucaena had a high content of tannins and moderate levels of saponins. Morus contained moderate amounts of saponins. The inclusion of 15% Leucaena and Gliricidia, 20% Sapindus and Arachis as well as 40% S. aterrimum, negatively affected protozoal populations. The inclusion of 25% Sapindus, Morus and Trichantera foliages using P. purpureum as the pasture base reduced CH4 production significantly. The results suggest that the use of trees and shrubs to supplement low quality forages seems appropriate for reducing CH4 production and improving animal nutrition in tropical areas. (author)

  7. Reducing subsistence farmers’ vulnerability to climate change: evaluating the potential contributions of agroforestry in western Kenya

    Thorlakson Tannis

    2012-10-01

    Full Text Available Abstract Subsistence farmers are among the people most vulnerable to current climate variability. Climate models predict that climate change will lead to warmer temperatures, increasing rainfall variability, and increasing severity and frequency of extreme weather events. Agroforestry, or the intentional use of trees in the cropping system, has been proposed by many development practitioners as a potential strategy to help farmers reduce their vulnerability to climate change. This study explores whether and, if so, how agroforestry techniques can help subsistence farmers reduce their vulnerability to climate change. From field research conducted in western Kenya, we find that households are not currently coping with climate-related hazards in a sustainable way. Farmers are aware of this, and believe that the most effective way to adapt to climate-related shocks is through improving their general standard of living. We evaluated agroforestry as one possible means of improving farmers’ well-being. By comparing farmers engaged in an agroforestry project with a control group of neighboring farmers, we find that involvement in agroforestry improves household’s general standard of living via improvements in farm productivity, off-farm incomes, wealth and the environmental conditions of their farm. We conclude that agroforestry techniques can be used as an effective part of a broader development strategy to help subsistence farmers reduce their vulnerability to climate-related hazards.

  8. Defining indicators to motorize block valves aiming to reduce potential leakage applied to OSBRA pipeline

    Pires, L.F.G. [Pontificia Universidade Catolica do Rio de Janeiro (PUC-Rio), RJ (Brazil); Sousa, A.G.; Castro, N.C.; Spagnolo, R. [Petrobras Transporte S.A. (TRANSPETRO), Rio de Janeiro, RJ (Brazil)

    2009-07-01

    The discussion about motorizing block valves is a constant point being brought up when it is intended to control or reduce the amount of liquid leaking in the event of a pipe rupture. During the pipeline's project stage the installation of blocking valves along the pipeline must be taken into consideration to meet the operation and maintenance requirements as well as to reduce the potential amounts of volume being leaked. In existing pipelines, the main concern is the definition of which valves are candidates to be motorized. In both situations criteria should be established to define this choice. A math algorithm was developed to define the potential leakage due to gravity along the pipeline profile where the influence of a valve over another is verified, as well as the contribution of the check valves existing in the pipeline. The present work defines a parameter based on the extension protected by the valve and the reduction of the potential leakage. This parameter is then fed to a worksheet where the efficiency indicators are calculated to each valve eligible to be motorized. It also takes into consideration factors relative to the valve location, such as the environmental sensitivity, risk assessment, social diagnosis and device's proximity to contingency resources. Finally, after considering all the above aspects, it's possible to come up with a final classification, recommending specific valves to be prioritized on an eventual process of motorization adequacies. This methodology was applied, experimentally on a pipe segment of TRANSPETRO's Sao Paulo-Brasilia pipeline - OSBRA , where it proved to be an important technological and management tool. (author)

    The development of new therapeutic strategies for the treatment of complex brain disorders such as drug addiction is likely to be advanced by a more complete understanding of the underlying molecular pathophysiology. Although the study of postmortem human brain represents a unique resource in this regard, it can be challenging to disentangle the relative contribution of chronic pathological processes versus perimortem events to the observed changes in gene expression. To begin to unravel this issue, we analyzed by quantitative PCR the midbrain expression of numerous candidate genes previously associated with cocaine abuse. Data obtained from chronic cocaine abusers (and matched control subjects) dying of gunshot wounds were compared with a prior study of subjects with deaths directly attributable to cocaine abuse. Most of the genes studied (i.e., tyrosine hydroxylase, dopamine transporter, forkhead box A2, histone variant H3 family 3B, nuclear factor kappa B inhibitor alpha, growth arrest and DNA damage-inducible beta) were found to be differentially expressed in chronic cocaine abusers irrespective of immediate cause of death or perimortem levels of cocaine, suggesting that these may represent core pathophysiological changes arising with chronic drug abuse. On the other hand, chemokine C-C motif ligand 2 and jun proto-oncogene expression were unaffected in cocaine-abusing subjects dying of gunshot wounds, in contrast to the differential expression previously reported in cocaine-related fatalities. The possible influence of cause of death and other factors on the cocaine-responsiveness of these genes is discussed. PMID:25658879

  13. Climate change reduces warming potential of nitrous oxide by an enhanced Brewer-Dobson circulation

    Kracher, Daniela; Reick, Christian H.; Manzini, Elisa; Schultz, Martin G.; Stein, Olaf

    2016-06-01

    The Brewer-Dobson circulation (BDC), which is an important driver of the stratosphere-troposphere exchange, is expected to accelerate with climate change. One particular consequence of this acceleration is the enhanced transport of nitrous oxide (N2O) from its sources at the Earth's surface toward its main sink region in the stratosphere, thus inducing a reduction in its lifetime. N2O is a potent greenhouse gas and the most relevant currently emitted ozone-depleting substance. Here we examine the implications of a reduced N2O lifetime in the context of climate change. We find a decrease in its global warming potential (GWP) and, due to a decline in the atmospheric N2O burden, also a reduction in its total radiative forcing. From the idealized transient global warming simulation we can identify linear regressions for N2O sink, lifetime, and GWP with temperature rise. Our findings are thus not restricted to a particular scenario.

  14. Reduced greenhouse gas mitigation potential of no-tillage soils through earthworm activity.

    Lubbers, Ingrid M; van Groenigen, Kees Jan; Brussaard, Lijbert; van Groenigen, Jan Willem

    2015-01-01

    Concerns about rising greenhouse gas (GHG) concentrations have spurred the promotion of no-tillage practices as a means to stimulate carbon storage and reduce CO2 emissions in agro-ecosystems. Recent research has ignited debate about the effect of earthworms on the GHG balance of soil. It is unclear how earthworms interact with soil management practices, making long-term predictions on their effect in agro-ecosystems problematic. Here we show, in a unique two-year experiment, that earthworm presence increases the combined cumulative emissions of CO2 and N2O from a simulated no-tillage (NT) system to the same level as a simulated conventional tillage (CT) system. We found no evidence for increased soil C storage in the presence of earthworms. Because NT agriculture stimulates earthworm presence, our results identify a possible biological pathway for the limited potential of no-tillage soils with respect to GHG mitigation. PMID:26337488

    2012-06-01

    Full Text Available Iron has been suggested to reduce the erosive potential of cola drinks in vitro.OBJECTIVE: The aim of this study was to evaluate in situ the effect of ferrous sulfate supplementation on the inhibition of the erosion caused by a cola drink. MATERIAL AND METHODS: Ten adult volunteers participated in a crossover protocol conducted in two phases of 5 days, separated by a washout period of 7 days. In each phase, they wore palatal devices containing two human enamel and two human dentin blocks. The volunteers immersed the devices for 5 min in 150 mL of cola drink (Coca-ColaTM, pH 2.6, containing ferrous sulfate (10 mmol/L or not (control, 4 times per day. The effect of ferrous sulfate on the inhibition of erosion was evaluated by profilometry (wear. Data were analyzed by paired t tests (p<0.05. RESULTS: The mean wear (±se was significantly reduced in the presence of ferrous sulfate, both for enamel (control: 5.8±1.0 µm; ferrous sulfate: 2.8±0.6 µm and dentin (control: 4.8±0.8 µm; ferrous sulfate: 1.7±0.7 µm. CONCLUSIONS: The supplementation of cola drinks with ferrous sulfate can be a good alternative for the reduction of their erosive potential. Additional studies should be done to test if lower ferrous sulfate concentrations can also have a protective effect as well as the combination of ferrous sulfate with other ions.

  16. Modifying welding process parameters can reduce the neurotoxic potential of manganese-containing welding fumes

    Welding fumes (WF) are a complex mixture of toxic metals and gases, inhalation of which can lead to adverse health effects among welders. The presence of manganese (Mn) in welding electrodes is cause for concern about the potential development of Parkinson’s disease (PD)-like neurological disorder. Consequently, from an occupational safety perspective, there is a critical need to prevent adverse exposures to WF. As the fume generation rate and physicochemical characteristics of welding aerosols are influenced by welding process parameters like voltage, current or shielding gas, we sought to determine if changing such parameters can alter the fume profile and consequently its neurotoxic potential. Specifically, we evaluated the influence of voltage on fume composition and neurotoxic outcome. Rats were exposed by whole-body inhalation (40 mg/m3; 3 h/day × 5 d/week × 2 weeks) to fumes generated by gas–metal arc welding using stainless steel electrodes (GMA-SS) at standard/regular voltage (25 V; RVSS) or high voltage (30 V; HVSS). Fumes generated under these conditions exhibited similar particulate morphology, appearing as chain-like aggregates; however, HVSS fumes comprised of a larger fraction of ultrafine particulates that are generally considered to be more toxic than their fine counterparts. Paradoxically, exposure to HVSS fumes did not elicit dopaminergic neurotoxicity, as monitored by the expression of dopaminergic and PD-related markers. We show that the lack of neurotoxicity is due to reduced solubility of Mn in HVSS fumes. Our findings show promise for process control procedures in developing prevention strategies for Mn-related neurotoxicity during welding; however, it warrants additional investigations to determine if such modifications can be suitably adapted at the workplace to avert or reduce adverse neurological risks

  17. Assessing the potential of hybrid energy technology to reduce exhaust emissions from global shipping

    The combination of a prime mover and an energy storage device for reduction of fuel consumption has successfully been used in automotive industry. The shipping industry has utilised this for conventional submarines. The potential of a load levelling strategy through use of a hybrid battery–diesel–electric propulsion system is investigated. The goal is to reduce exhaust gas emissions by reducing fuel oil consumption through consideration of a re-engineered ship propulsion system. This work is based on operational data for a shipping fleet containing all types of bulk carriers. The engine loading and the energy requirements are calculated, and sizing of suitable propulsion and the battery storage system are proposed. The changes in overall emissions are estimated and the potential for fuel savings identified. The efficiency of the system depends on the storage medium type, the availability of energy and the displacement characteristics of the examined vessels. These results for the global fleet indicate that savings depending on storage system, vessel condition and vessel type could be up to 0.32 million tonnes in NOx, 0.07 million tonnes in SOx and 4.1 million tonnes in CO2. These represent a maximum 14% of reduction in dry bulk sector and 1.8% of world's fleet emissions. - Highlights: ► Global shipping makes a significant contribution to CO2, SOx and NOx emissions. ► We examine noon reports from a fleet of bulk carriers to identify the amount engine is operating off design. ► A hybrid propulsion system is proposed that uses multiple diesel–electric generators and battery storage. ► Analysis indicates hybrid may give an attractive rate of return as well as emissions savings in emissions. ► Implementation will require review of class society regulations.

  19. Surveillance indicators for potential reduced exposure products (PREPs: developing survey items to measure awareness

    McNeill Ann

    2009-10-01

    Full Text Available Abstract Background Over the past decade, tobacco companies have introduced cigarettes and smokeless tobacco products (known as Potential Reduced Exposure Products, PREPs with purportedly lower levels of some toxins than conventional cigarettes and smokeless products. It is essential that public health agencies monitor awareness, interest, use, and perceptions of these products so that their impact on population health can be detected at the earliest stages. Methods This paper reviews and critiques existing strategies for measuring awareness of PREPs from 16 published and unpublished studies. From these measures, we developed new surveillance items and subjected them to two rounds of cognitive testing, a common and accepted method for evaluating questionnaire wording. Results Our review suggests that high levels of awareness of PREPs reported in some studies are likely to be inaccurate. Two likely sources of inaccuracy in awareness measures were identified: 1 the tendency of respondents to misclassify "no additive" and "natural" cigarettes as PREPs and 2 the tendency of respondents to mistakenly report awareness as a result of confusion between PREPs brands and similarly named familiar products, for example, Eclipse chewing gum and Accord automobiles. Conclusion After evaluating new measures with cognitive interviews, we conclude that as of winter 2006, awareness of reduced exposure products among U.S. smokers was likely to be between 1% and 8%, with the higher estimates for some products occurring in test markets. Recommended measurement strategies for future surveys are presented.

  20. Rapid Biosynthesis of Silver Nanoparticles by Exploiting the Reducing Potential of Trapa bispinosa Peel Extract

    Present work reports exceptionally high reducing capacity of Trapa bispinosa to synthesize monodispersed silver nanoparticles (SNPs) within 120 seconds at 30 degree C which is the shortest tenure reported for SNP synthesis using plants. Moreover, we also instigated impact of different ph values on fabrication of SNPs using visible spectroscopy with respect to time. Percentage conversion of Ag+ ions into Ag was calculated using ICP-AES analysis and was found to be 97% at pH = 7. To investigate the reduction of Ag+ ions to SNPs, cyclic voltammetry (CV) and open circuit potential (OCP) using 0.1M KNO3 were performed. There was prompt reduction in cathodic and anodic currents after addition of the peel extract which indicates the reducing power of T. bispinosa peel. Stability of the SNPs was studied using flocculation parameter (FP) which was found to be least at all the pH values. FP was found to be indirectly proportional to stability of the nanoparticles

  1. Transient Receptor Potential Channel 1 (TRPC1) Reduces Calcium Permeability in Heteromeric Channel Complexes

    Storch, Ursula; Forst, Anna-Lena; Philipp, Maximilian; Gudermann, Thomas; Mederos y Schnitzler, Michael

    2012-01-01

    Specific biological roles of the classical transient receptor potential channel 1 (TRPC1) are still largely elusive. To investigate the function of TRPC1 proteins in cell physiology, we studied heterologously expressed TRPC1 channels and found that recombinant TRPC1 subunits do not form functional homomeric channels. Instead, by electrophysiological analysis TRPC1 was shown to form functional heteromeric, receptor-operated channel complexes with TRPC3, -4, -5, -6, and -7 indicating that TRPC1 proteins can co-assemble with all members of the TRPC subfamily. In all TRPC1-containing heteromers, TRPC1 subunits significantly decreased calcium permeation. The exchange of select amino acids in the putative pore-forming region of TRPC1 further reduced calcium permeability, suggesting that TRPC1 subunits contribute to the channel pore. In immortalized immature gonadotropin-releasing hormone neurons endogenously expressing TRPC1, -2, -5, and -6, down-regulation of TRPC1 resulted in increased calcium permeability and elevated basal cytosolic calcium concentrations. We did not observe any involvement of TRPC1 in store-operated cation influx. Notably, TRPC1 suppressed the migration of gonadotropin-releasing hormone neurons without affecting cell proliferation. Conversely, in TRPC1 knockdown neurons, specific migratory properties like distance covered, locomotion speed, and directionality were increased. These findings suggest a novel regulatory mechanism relying on the expression of TRPC1 and the subsequent formation of heteromeric TRPC channel complexes with reduced calcium permeability, thereby fine-tuning neuronal migration.

  2. Antioxidant potential of tea reduces arsenite induced oxidative stress in Swiss albino mice.

    Sinha, D; Roy, S; Roy, M

    2010-04-01

    Environmental arsenic (As) is a potent human carcinogen and groundwater As contamination is a major health concern in West Bengal, India. Oxidative stress has been one of the prime factors in As-induced carcinogenicity. Generation of reactive oxygen species (ROS), beyond the body's endogenous antioxidant balance cause a severe imbalance of the cellular antioxidant defence mechanism. Tea, a popular beverage has excellent chemopreventive and antioxidant properties. In this study it was investigated whether these flavonoids could ameliorate the arsenite (As III) induced oxidative stress in Swiss albino mice. Bio-monitoring with comet assay elicited that the increase in genotoxicity caused by As III was counteracted by both black tea and green tea. Elevated levels of lipid peroxides and protein carbonyl by As III were effectively reduced with green as well as black tea. They also exhibited protective action against the As III induced depletion of antioxidants like catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GR), glutathione-S-transferase (GST) and glutathione (GSH) in mice liver tissue. Thus the tea polyphenols by virtue of their antioxidant potential may be used as an effective agent to reduce the As III induced oxidative stress in Swiss albino mice. PMID:20096321

  3. Can a cognitive-behavioral group-therapy training program for the treatment of child sexual abuse reduce levels of burnout and job-strain in trainees? initial evidence of a brazilian model

    Bruno Figueiredo Damásio

    2014-05-01

    Full Text Available This study evaluated the extent to which a professional training program of an evidence-based intervention for the treatment of child and adolescent victims of sexual abuse could reduce strain and burnout levels in trainees. Participants were 30 psychologists, 19 of whom composed the experimental group (G1 and 11 the comparison group (G2. Data collection occurred before and after the training. The results showed that the ‘work demand’ increased for G1 and remained stable for G2, whereas the ‘control at work’ remained stable for G1 while decreasing for G2. Regarding burnout levels, there was a decrease in depersonalization and stabilization in the levels of emotional exhaustion and reduced professional efficacy for G1, whereas for G2, all the burnout indicators significantly increased. These results partially support the perspective that the training program would have an indirect protective effect on the occupational psychopathology levels of the trainees.

  6. Thorium fuel for light water reactors - reducing proliferation potential of nuclear power fuel cycle

    The proliferation potential of the light water reactor fuel cycle may be significantly reduced by utilization of thorium as a fertile component of the nuclear fuel. The main challenge of Th utilization is to design a core and a fuel cycle, which would be proliferation-resistant and economically feasible. This challenge is met by the Radkowsky Thorium Reactor (RTR) concept. So far the concept has been applied to a Russian design of a 1,000 MWe pressurized water reactor, known as a WWER-1000, and designated as VVERT. The following are the main results of the preliminary reference design: * The amount of Pu contained in the RTR spent fuel stockpile is reduced by 80% in comparison with a VVER of a current design. * The isotopic composition of the RTR-Pu greatly increases the probability of pre-initiation and yield degradation of a nuclear explosion. An extremely large Pu-238 content causes correspondingly large heat emission, which would complicate the design of an explosive device based on RTR-Pu. The economic incentive to reprocess and reuse the fissile component of the RTR spent fuel is decreased. The once-through cycle is economically optimal for the RTR core and cycle. To summarize all the items above: the replacement of a standard (U-based) fuel for nuclear reactors of current generation by the RTR fuel will provide an inherent barrier for nuclear weapon proliferation. This inherent barrier, in combination with existing safeguard measures and procedures is adequate to unambiguously disassociate civilian nuclear power from military nuclear power. * The RTR concept is applied to existing power plants to assure its economic feasibility. Reductions in waste disposal requirements, as well as in natural U and fabrication expenses, as compared to a standard WWER fuel, provide approximately 20% reduction in fuel cycle (authors)

  7. Prospective use of bacteriocinogenic Pediococcus pentosaceus as direct-fed microbial having methane reducing potential

    2015-01-01

    Direct-fed microbials (DFM), general y regarded as safe status, are successful y used in improving rumen ecology, gastro-in-testinal health, feed efifciency, milk production and growth rate in ruminants. On the other hand, methanogenesis in rumen, which accounts for a signiifcant loss of ruminant energy and increased greenhouse gas in environment, is of great concern, therefore, use of DFM for improving productivity without compromising the animal health and ecological sustainability is encouraged. The present study was conducted to investigate the methane reducing potential of bacteriocinogenic strain Pediococcus pentosaceus-34. Since, the culture showed no hemolysis on blood agar and DNase activity, hence, it was considered to be avirulent in nature, a prerequisite for any DFM. The culture also showed tolerance to pH 5.0 for 24 h with 0.5%organic acid mixture, whereas when given a shock for 2 h at different pH and organic acids concentrations, it showed growth at pH 3.0 and 4.0 with 0.1 and 1.0%organic acids, respectively, as having good animal probiotics attributes. The total gas production was signiifcantly (P<0.05) higher in live pedicoccal culture (LPC) and dead pedicoccal culture (DPC) both with wheat straw, when compared to the control. In sugarcane bagasse, gas production was signiifcantly lower (P<0.05) with LPC compared to the control and DPC both. Methane was reduced by the inclusion of LPC in sugarcane bagasse (0.07 mL CH4 mg–1 dry matter digestibility) with no effect on other rumen fermentation parameters. However, with wheat straw and LPC total gas, in vitro dry matter digestibility, total volatile fatty acids increased signiifcantly but no reduction in methane production was observed in comparison to the control. Therefore, further research is warranted in this direction, if the bacteriocinogenic strains can be used as DFM for ruminants to improve the ruminant productivity.

  8. Low luminance/eyes closed and monochromatic stimulations reduce variability of flash visual evoked potential latency

    Senthil Kumar Subramanian

    2013-01-01

    Full Text Available Context: Visual evoked potentials are useful in investigating the physiology and pathophysiology of the human visual system. Flash visual evoked potential (FVEP, though technically easier, has less clinical utility because it shows great variations in both latency and amplitude for normal subjects. Aim: To study the effect of eye closure, low luminance, and monochromatic stimulation on the variability of FVEPs. Subjects and Methods: Subjects in self-reported good health in the age group of 18-30 years were divided into three groups. All participants underwent FVEP recording with eyes open and with white light at 0.6 J luminance (standard technique. Next recording was done in group 1 with closed eyes, group 2 with 1.2 and 20 J luminance, and group 3 with red and blue lights, while keeping all the other parameters constant. Two trials were given for each eye, for each technique. The same procedure was repeated at the same clock time on the following day. Statistical Analysis: Variation in FVEP latencies between the individuals (interindividual variability and the variations within the same individual for four trials (intraindividual variability were assessed using coefficient of variance (COV. The technique with lower COV was considered the better method. Results: Recording done with closed eyes, 0.6 J luminance, and monochromatic light (blue > red showed lower interindividual and intraindividual variability in P2 and N2 as compared to standard techniques. Conclusions: Low luminance flash stimulations and monochromatic light will reduce FVEP latency variability and may be clinically useful modifications of FVEP recording technique.

  9. Genetic parameters for predicted methane production and potential for reducing enteric emissions through genomic selection.

    Haas, Y de; Windig, J J; Calus, M P L; Dijkstra, J; Haan, M de; Bannink, A; Veerkamp, R F

    2011-12-01

    Mitigation of enteric methane (CH₄) emission in ruminants has become an important area of research because accumulation of CH₄ is linked to global warming. Nutritional and microbial opportunities to reduce CH₄ emissions have been extensively researched, but little is known about using natural variation to breed animals with lower CH₄ yield. Measuring CH₄ emission rates directly from animals is difficult and hinders direct selection on reduced CH₄ emission. However, improvements can be made through selection on associated traits (e.g., residual feed intake, RFI) or through selection on CH₄ predicted from feed intake and diet composition. The objective was to establish phenotypic and genetic variation in predicted CH₄ output, and to determine the potential of genetics to reduce methane emissions in dairy cattle. Experimental data were used and records on daily feed intake, weekly body weights, and weekly milk production were available from 548 heifers. Residual feed intake (MJ/d) is the difference between net energy intake and calculated net energy requirements for maintenance as a function of body weight and for fat- and protein-corrected milk production. Predicted methane emission (PME; g/d) is 6% of gross energy intake (Intergovernmental Panel on Climate Change methodology) corrected for energy content of methane (55.65 kJ/g). The estimated heritabilities for PME and RFI were 0.35 and 0.40, respectively. The positive genetic correlation between RFI and PME indicated that cows with lower RFI have lower PME (estimates ranging from 0.18 to 0.84). Hence, it is possible to decrease the methane production of a cow by selecting more-efficient cows, and the genetic variation suggests that reductions in the order of 11 to 26% in 10 yr are theoretically possible, and could be even higher in a genomic selection program. However, several uncertainties are discussed; for example, the lack of true methane measurements (and the key assumption that methane

    2012-10-01

    Human resources for health have many diverse aspects that sometimes bring about conflicts in the healthcare market. In recent decades issues such as attrition, migration, and different types of imbalances in health workers were not only considered as international problems, but also took on new particular dimensions and complications. Rapid growth in establishing infrastructure of communications and many diseases such as human immunodeficiency virus/AIDS and malaria, as well as shortages in skilled healthcare providers in developing countries, interested many health economists and health professionals to consider telemedicine as an approach to deliver some healthcare and to pursue its effects on human resources management in healthcare. The objective of this communication is to offer a better understanding of the value of telemedicine in human resources management in healthcare. This article briefly reviews related literature on potential contributions of telemedicine in mitigating four different types of imbalances in health workers and points out some of its capabilities. Although there is a great need for systematic, scientific, and analytical studies in effects of telemedicine on health workers, expansion of communication infrastructure throughout and especially in remote areas, political commitment, and provision of useful information and education to reduce problems of human resources for health are beneficial.

  11. Estimating Potential and Costs of Reducing CO2 Emissions in Lithuanian Buildings

    Eglė Jaraminienė

    2012-03-01

    Full Text Available The EU is considering increasing the GHG emissions reduction target by 2020 from 20% to 30% by committing each member state to tighten up its emission reduction goals. According to the recent study such decision could cost some 2 365 million LTL to Lithuanian economy. Evaluation and comparison of CO2 abatement costs incurred by the state implementing a variety of measures in different sectors allow choosing a most cost effective policy scenario. The paper focuses on CO2 emissions related to energy use in buildings. First, this paper reviews the role of the Lithuanian building stock in overall GHG emissions. Then the paper examines the existing studies on the CO2 mitigation potential and cost in buildings. Given the limitations of existing evaluation and lack of comprehensive modelling in the existing studies, this paper proposes a framework for examining the technology options aimed to inform policy making on the options to reduce CO2 emissions in Lithuanian housing and service sectors.DOI: http://dx.doi.org/10.5755/j01.erem.59.1.680

  13. Reducing symbolic-violence in the research encounter: collaborating with a survivor of domestic abuse in a qualitative study in UK primary care.

    Malpass, Alice; Sales, Kim; Feder, Gene

    2016-03-01

    This paper explores ideas of symbolic violence inherent in the research encounter (Bourdieu 1999). After defining symbolic violence and how the concept enters into domestic violence and abuse (DVA) research, we discuss the challenges arising from a (DVA) survivor taking on the role of interviewer in a qualitative study nested within a UK primary care based trial: IRIS (Identification and Referral to Improve Safety). KS, a survivor of DVA, conducted interviews with 12 women who had been referred to a domestic violence agency by primary care clinicians taking part in the IRIS trial in two UK cities (Bristol and east London) during 2009. Field notes were kept during all of the research meetings with KS and these were included in analysis. Our analysis maps the research pathway of 'non-violent communication' and discusses the role of social symmetry and proximity in the research encounter. We conclude that while a welcoming disposition, empathy and active listening are all generic skills to qualitative research; if a researcher can enter fieldwork with a claim of social proximity and symmetry, their use of these generic skills is enhanced through a process of shared objectification and empowerment talk. We explore the limitations of social proximity, its relationship to feminist and anthropological theories of 'insider' research and its relevance to primary care research. PMID:26403218

    Yixin H Ye

    Full Text Available Dengue viruses (DENV are the causative agents of dengue, the world's most prevalent arthropod-borne disease with around 40% of the world's population at risk of infection annually. Wolbachia pipientis, an obligate intracellular bacterium, is being developed as a biocontrol strategy against dengue because it limits replication of the virus in the mosquito. The Wolbachia strain wMel, which has been introduced into the mosquito vector, Aedes aegypti, has been shown to invade and spread to near fixation in field releases. Standard measures of Wolbachia's efficacy for blocking virus replication focus on the detection and quantification of virus in mosquito tissues. Examining the saliva provides a more accurate measure of transmission potential and can reveal the extrinsic incubation period (EIP, that is, the time it takes virus to arrive in the saliva following the consumption of DENV viremic blood. EIP is a key determinant of a mosquito's ability to transmit DENVs, as the earlier the virus appears in the saliva the more opportunities the mosquito will have to infect humans on subsequent bites.We used a non-destructive assay to repeatedly quantify DENV in saliva from wMel-infected and Wolbachia-free wild-type control mosquitoes following the consumption of a DENV-infected blood meal. We show that wMel lengthens the EIP, reduces the frequency at which the virus is expectorated and decreases the dengue copy number in mosquito saliva as compared to wild-type mosquitoes. These observations can at least be partially explained by an overall reduction in saliva produced by wMel mosquitoes. More generally, we found that the concentration of DENV in a blood meal is a determinant of the length of EIP, saliva virus titer and mosquito survival.The saliva-based traits reported here offer more disease-relevant measures of Wolbachia's effects on the vector and the virus. The lengthening of EIP highlights another means, in addition to the reduction of infection

  19. Training Teachers to Identify and Intervene with Abused Children.

    Hazzard, Ann; Rupp, Gary

    Teachers are a potentially helpful resource for abused children, but generally lack training in child abuse identification and intervention. Elementary and junior high school teachers (N=104) were surveyed concerning their abuse-related experience, knowledge and attitudes. Sixty-eight percent of the teachers reported 3 or fewer hours of education…

    Child abuse is a major public health concern that can explain a proportion of fractures in children. Osteogenesis imperfecta (OI) is the most common inherited syndrome that predisposes to skeletal fractures. We conducted a retrospective analysis of data from clinical, laboratory, and radiographic information from children evaluated for child abuse in which molecular testing for COL1A1 and COL1A2 genes was conducted. A total of 43 patients underwent molecular testing for OI. Pathogenic variants predicted to result in a mild form of OI were found in two patients (5%), both clinically suspected to have this diagnosis. None of the cases in whom OI molecular testing was ordered when maltreatment concerns were thought to be more likely (0/35) were identified to have pathogenic variants. After reviewing each individual case, the final diagnosis was child abuse for 34 cases (77%), and additional radiographic and laboratory studies did not identify any with inherited metabolic predisposition to fracture or rickets. We conclude that routine testing for OI in the setting of child abuse when no other suggestive clinical findings are present has a low yield. A careful review of the medical history and a detailed clinical evaluation help identify those at risk for genetic alterations. © 2016 Wiley Periodicals, Inc. PMID:27090748

  1. Potential autotrophic metabolisms in ultra-basic reducing springs associated with present-day continental serpentinization

    Ultra-basic reducing springs at continental sites of serpentinization act as windows into the biogeochemistry of this subsurface exothermic environment rich in H2 and CH4 gases. Biogeochemical carbon transformations in these systems are of interest because serpentinization creates conditions that are amenable to abiotic and biotic reduction of carbon. However, little is known about the metabolic capabilities of the microorganisms that live in this environment. To determine the potential for autotrophic metabolisms, bicarbonate and CO substrate addition microcosm experiments were performed using water and sediment from an ultra-basic reducing spring in the Tablelands, Newfoundland, Canada, a site of present-day continental serpentinization. CO was consistently observed to be utilized in the Live but not the Killed controlled replicates amended with 10% 13C labelled CO and non-labelled (natural C isotope abundance) CO. In the Live CO microcosms with natural C isotope abundance, the residual CO became enriched in 13C (~10 ‰) consistent with a decrease in the fraction of CO remaining. In the Killed CO controlled replicates with natural C isotope abundance the CO showed little 13C enrichment (~1.3 ‰). The data from the Live CO microcosms were well described by a Rayleigh isotopic distillation model, yielding an isotopic enrichment factor for microbial CO uptake of 15.7 ×0.5 ‰ n=2. These data suggest that there was microbial CO utilization in these experiments. The sediment and water from the 13C-labelled and non-labelled, Live and Killed microcosms were extracted for phospholipid fatty acids (PLFAs) to determine changes in community composition between treatments as well as to determine the microbial uptake of CO. The difference in community composition between the Live and Killed microcosms was not readily resolvable based on PLFA distributions. Additionally, the microbial uptake of 13CO had minimal to no affect on the δ13C of the cellular biomarkers, with the

  2. Reducing automotive emissions—The potentials of combustion engine technologies and the power of policy

    Reducing transport emissions, in particular vehicular emissions, is a key element for mitigating the risks of climate change. In much of the academic and public discourse the focus has been on alternative vehicle technologies and fuels (e.g. electric cars, fuel cells and hydrogen), whereas vehicles based on internal combustion engines have been perceived as close to their development limits. This paper offers a different perspective by demonstrating the accelerated improvement processes taking place in established combustion technologies as a result of a new competition between manufacturers and technologies, encouraged both by more stringent EU legislation and new CAFE levels in the US. The short-term perspective is complemented by an analysis of future improvement potentials in internal combustion technologies, which may be realized if efficient regulation is in place. Based on a comparison of four different regulatory approaches, the paper identifies the need for a long-term technology-neutral framework with stepwise increasing stringencies, arguing that this will encourage continual innovation and diffusion in the most effective way. - Highlights: ► From 1990 to 2008, CO2 emissions from road transportation in the EU increased by 21%. ► Alternative vehicles are important, but internal combustion engines (ICE) will remain dominant. ► The paper shows how competition and new regulation accelerate the improvement of ICE-vehicles. ► The key factor for long-term emissions reduction is appropriate regulation, not technology. ► Most effective is a technology-neutral framework with stepwise increasing stringencies.

  3. IRRITABLE BOWEL SYNDROME: Relationships with Abuse in Childhood

    Sansone, Randy A.; Sansone, Lori A.

    2015-01-01

    Irritable bowel syndrome is allegedly the most common gastrointestinal diagnosis in the United States. The etiology of this syndrome appears to entail the interaction of both genes and the environment. One potential environmental contributory factor to irritable bowel syndrome is abuse in childhood. Of the various forms of abuses previously examined, sexual abuse in childhood appears to be the most patent contributor. However, both emotional and physical abuses may also contribute to irritabl...

  4. Oral and dental aspects of child abuse

    2006-06-01

    Full Text Available Child abuse is defined as those acts or omissions of care that deprive a child from the opportunity to fully develop his or her unique potentials as a person either physically, socially or emotionally. The overall incidence of child abuse is not really clear. Statistical data do not show the actual rate because of the unreported cases. Dentists are in a strategic position to recognize and report the children being abused because they often see the child and parents interacting during multiple visits and over a long period of time. The orofacial region is commonly traumatized during episodes of child abuse. The characteristics and diagnostic finding of child abuse, and the protocol of reporting such cases, should be familiar to the dentist so that appropriate notification, treatment and prevention of further injury can be instituted. Dentists with experience or expertise in child abuse and neglect will strengthen their ability to prevent and detect child abuse and neglect and enhance the ability to care for and protect children. This paper discusses the oral and dental aspects of child abuse and the dentist role in evaluating this situation including prevention of child abuse.

    Biocathodes polarized at high potential are promising for enhancing Microbial Fuel Cell performances but the microbes and genes involved remain poorly documented. Here, two sets of five oxygen-reducing biocathodes were formed at two potentials (-0.4V and +0.1V vs. saturated calomel electrode) and analyzed combining electrochemical and metagenomic approaches. Slower start-up but higher current densities were observed at high potential and a distinctive peak increasing over time was recorded on cyclic voltamogramms, suggesting the growth of oxygen reducing microbes. 16S pyrotag sequencing showed the enrichment of two operational taxonomic units (OTUs) affiliated to Ectothiorodospiraceae on high potential electrodes with the best performances. Shotgun metagenome sequencing and a newly developed method for the identification of Taxon Specific Gene Annotations (TSGA) revealed Ectothiorhodospiraceae specific genes possibly involved in electron transfer and in autotrophic growth. These results give interesting insights into the genetic features underlying the selection of efficient oxygen reducing microbes on biocathodes. PMID:27126080

  6. [Intra and extra-familiar sexual abuse].

    Taveira, Francisco; Frazão, Sofia; Dias, Ricardo; Matos, Eduarda; Magalhães, Teresa

    2009-01-01

    The sexual abuse of a child or young person constitutes a major social and public health problem and there is recent evidence that intra-familial (IF) sexual abuses are more serious in their consequences than extra-familial (EF). However, there are no studies on this phenomenon in Portugal. Thus, the aim of the present study is to contribute to a better characterization of these types of abuses and to identify possible differences between IF and EF cases. A retrospective study was preformed based on medico-legal reports related to victims below the age of 18, suspected of being sexually abused (n = 764), corresponding to 67% of the total of observed sexual crimes. Results revealed that 34.9% of the abuses are IF and they show statistically significant differences when compared to EF cases. These are due to the following factors found in IF situations: a) lower victim age; b) closeness between victim and abuser; c) abusers with a higher rate of previous sexual abuse; d) sexual practices of reduced physical intrusion; e) decreased physical violence but increased emotional violence; f) greater delay between last abuse and the forensic exam; g) reduced number of injuries or biological evidence (none in the great majority of the cases). Results point out the existence of several characteristics in IF abuse that have been identified as factors that influence the severity of the abuse consequences. Among them are: a) lower victim age; b) greater proximity to the abuser; c) increased amount of emotional violence. These factors account for the reduced visibility of this kind of cases and therefore explain their delayed disclosure and diagnosis. The association of this fact with the reduced intrusiveness of this sort of practice and the consequent decrease in number of injuries and other evidence leads to a marked reduction of the number of cases where evidence of the abuse can be found by physical examination alone. The above aspects underlie the need of using different

    2014-09-01

    This work analyzes the seasonal variation (winter and summer) of ten drugs of abuse, six metabolites and three benzodiazepines in surface waters from the Jarama and Manzanares Rivers in the Madrid Region, the most densely populated area in Spain. The occurrence of these compounds in tap water in this region is also investigated and a preliminary human health risk characterization performed for those substances found in tap water. Finally, a screening level risk assessment that combines the measured environmental concentrations (MECs) with dose-response data to estimate Hazard Quotients (HQs) for the compounds studied is also presented. The results of this study show the presence of fourteen out of the nineteen compounds analyzed in winter and twelve of them in summer. The most ubiquitous compounds, with a frequency of detection of 100% in both seasons, were the cocaine metabolite benzoylecgonine (BE), the amphetamine-type stimulant (ATS) ephedrine (EPH), the opioid methadone (METH), the METH metabolite 2-ethylene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP), and the three benzodiazepines investigated, namely alprazolam (ALP), diazepam (DIA) and lorazepam (LOR). The highest concentrations observed corresponded to EPH (1020ngL(-1) in winter and 250ngL(-1) in summer). The only compounds not detected in both seasons were heroin (HER) and its metabolite 6-acetylmorphine (6ACM), lysergic acid diethylamide (LSD) and its metabolite 2-oxo-3-hydroxy-LSD (O-H-LSD), and Δ(9)-tetrahydrocannabinol (THC). In terms of overall concentration, all sampling points presented higher concentrations in winter than in summer. Statistical analyses performed to gather evidence concerning occasional seasonal differences in the concentrations of individual substances between summer and winter showed statistically significantly higher concentrations (pmetabolite 11-nor-9-carboxy-Δ(9)-tetrahydrocannabinol (THC-COOH) were present in at least one of the sampling sites in a concentration leading

    Full Text Available Methadone maintenance is one of the well-known harm reduction strategies for public health intervention in heroin addiction. The significance of methadone treatment in preventing needle sharing, which in turn reduces the risk of HIV and HCV transmission among injectors, has been demonstrated. Methadone maintenance is also considered gathering site where heroin addicts can effectively acquire knowledge on harm reduction and drug rehabilitation. We report a case of a 34-years-old patient with a history of heroin abuse. Therapy with methadone was essential for an adequate management of the case. The article describe difficulties and complexities of heroin abuse management and the therapeutic role of methadone.

    2016-05-01

    The number of oral fluid samples collected by the road policing authority in Victoria, Australia, requiring confirmatory laboratory analysis for drugs proscribed under Victorian legislation (methamphetamine, MDMA and Δ9-tetrahydrocannabinol) has greatly increased in recent years, driving the need for improved analysis techniques to enable expedient results. The aim of this study was to develop an LC-MS/MS-based targeted oral fluid screening technique that covers a broad range of basic and neutral drugs of abuse that can satisfy increased caseload while monitoring other compounds of interest for epidemiological purposes. By combining small sample volume, simple extraction procedure, rapid LC-MS/MS analysis and automated data processing, 40 drugs of abuse including amphetamines, benzodiazepines, cocaine and major metabolites, opioids, cannabinoids and some designer stimulants were separated over 5 min (with an additional 0.5 min re-equilibration time). The analytes were detected using a Sciex® API 4500 Q-Trap LC-MS/MS system with positive ESI in MRM mode monitoring three transitions per analyte. The method was fully validated in accordance with international guidelines and also monitored carbon-13 isotopes of MDMA and MA to reduce detector saturation effects, allowing for confirmation of large concentrations of these compounds without the need for dilution or re-analysis. The described assay has been successfully used for analysis of oral fluid collected as part of law enforcement procedures at the roadside in Victoria, providing forensic results as well as epidemiological prevalence in the population tested. The fast and reliable detection of a broad range of drugs and subsequent automated data processing gives the opportunity for high throughput and fast turnaround times for forensic toxicology.

    Full Text Available Sexual abuse is defined as use of child or adolescent by the adults for satisfying of sexual urges and needs with forcing, threatening or tricking. Sexual abuse can be in the form of sexual abuse without touch, sexual touch, interfemoral intercourse, sexual penetration, and sexual exploitation. The prevalence of sexual abuse is reported as 10-40%. It is seen in female four times more than in males. Abusers are frequently male, only 5-15% of them are female. The abuse by females is usually towards male child. Thirty-fifty percent of abuse cases among child and adolescent are outside the family including strangers or familiar person. Some features of abusers are introvert personality, pedophilic and antisocial personality. Most of the abusers have a history of sexual abuse or aggression during childhood. Sexual intercourse between two people who are not allowed to marry by law is called as incest. Family pattern of incest is defined globally as disorganized and dysfunctional. The most commonly reported familial pattern is rigid and patriarchal family pattern with a harsh father using force quite frequently. The clinical features and impacts of the sexual abuse on the child varies according to the relation between abusers and the child, form of abuse, duration of abuse, presence of physical assault, developmental phase, child age and psychological development before the abuse. Sexual abuse history may result in psychiatric disorders including anxiety, depression, substance dependence, suicide act, borderline personality disorder, posttraumatic stress disorder. Abuse negatively affects interpersonal relationships and self esteem of abused individuals. Several studies reported close association between risky sexual behaviors in adulthood and a history of of sexual abuse during childhood. Four traumatic dynamics including traumatic sexuality with abuse, feeling of betrayal, weakness, and stigmatization exist in childhood abuse. Trauma can cause

  15. Misuse and abuse of quetiapine

    Agnieszka Piróg-Balcerzak

    2015-02-01

    Full Text Available Quetiapine is an atypical antipsychotic agent, frequently used in psychiatry, often for symptomatic treatment against a number of mental disorders differing from the registration indications. One of the use is to soothe the clinical conditions caused by the use of various psychoactive substances. The paper presents and discusses the reports of quetiapine misuse, abuse, and even mental addiction, as well as symptoms similar to the so-called discontinuation syndrome, often mixed with withdrawal syndrome occurring in the course of addiction. Most reports concern males, and especially those with a history of other psychoactive substance abuse, and personality disorders, often in conflict with the law. Therefore, clinicians should be cautious when prescribing quetiapine to such patients. The article discusses potential mechanisms responsible for quetiapine abuse. This is probably related to its sedative and anxiolytic activity which results in the frequent use with stimulants. Also, high affinity for the H1 receptor, as antihistamines agents causes rewarding action.

  16. The potential of Yucca schidigera extract to reduce the ammonia pollution from shrimp farming.

    Santacruz-Reyes, Roberto A; Chien, Yew-Hu

    2012-06-01

    This study investigated the feasibility of using Yucca schidigera extract (YUPE) to reduce ammonia pollution resulting from shrimp farming. YUPE was added at ratios of 18, 36, and 72 mg L(-1) to effluent from an experimental shrimp culture system containing total ammonia nitrogen (TAN) of 0.592, 0.672, and 0.718 mg L(-1). TAN reduction increased with an increase in YUPE, and at 18 mg L(-1) reduced TAN by 71-72% and 86-87% at 6 and 24h, respectively. Shrimp feed containing YUPE at 300, 600, and 1200 mg kg(-1) was submerged, allowing the ammonia to leach out. The addition of YUPE in feed reduced TAN leaching by 50-83% compared with the control. The application of YUPE in water or feed could considerably reduce the accumulation of ammonia in waste water discharge during shrimp production, thereby providing a feasible solution to ammonia pollution in coastal environments.

  17. Reduced Zeta potential through use of cationic adhesion promoter for improved resist process performance and minimizing material consumption

    Hodgson, Lorna; Thompson, Andrew

    2012-03-01

    This paper presents the results of a non-HMDS (non-silane) adhesion promoter that was used to reduce the zeta potential for very thin (proprietary) polymer on silicon. By reducing the zeta potential, as measured by the minimum sample required to fully coat a wafer, the amount of polymer required to coat silicon substrates was significantly reduced in the manufacture of X-ray windows used for high transmission of low-energy X-rays. Moreover, this approach used aqueous based adhesion promoter described as a cationic surface active agent that has been shown to improve adhesion of photoresists (positive, negative, epoxy [SU8], e-beam and dry film). As well as reducing the amount of polymer required to coat substrates, this aqueous adhesion promoter is nonhazardous, and contains non-volatile solvents.

    Allogeneic stem cell transplantation (SCT) provides the best mechanism of preventing relapse in acute myeloid leukaemia (AML). However non-relapse mortality (NRM) negates this benefit in older patients. Reduced intensity conditioning (RIC) permits SCT with reduced NRM, but its contribution to cure...... is uncertain. In the MRC AML15 Trial, patients in remission without favourable risk disease could receive SCT from a matched sibling or unrelated donor (MUD). If aged >45 years, a RIC was recommended and in patients aged 35-44 years, either RIC or myeloablative conditioning was permitted. The aim...... was to determine which approach improved survival and within which prespecified cytogenetic groups. RIC transplants significantly reduced relapse (adjusted hazard ratio (HR) 0.66 (0.50-0.85), P=0.002) compared to chemotherapy The 5-year overall survival from a sibling RIC (61%) was superior to a MUD RIC (37...

    Cellulosic ethanol prices depend heavily on the cost of the cellulase enzymes used to break down the biomass into fermentable sugars. To reduce these costs, NREL partnered with two leading enzyme companies, Novozymes and Genencor, to engineer new cellulase enzymes that are exceptionally good at breaking down cellulose. Genencor is now part of DuPont Industrial Biosciences.

  10. Potential contribution of the Clean Coal Program to reducing global emissions of greenhouse gases

    Environmental considerations of Clean Coal Program (CCP) initially focused on reducing emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) to the atmosphere. However, it has also become apparent that some Clean Coal Technologies (CCTs) may contribute appreciably to reducing emissions of carbon dioxide (CO2), thereby diminishing the rate of any global warming that may result from greenhouse effects. This is particularly true for CCTs involving replacement of a major portion of an existing facility and/or providing the option of using a different fuel form (the repowering CCTs). Because the subject of global-scale climate warming is receiving increased attention, the effect of CCTs on Co2 emissions has become a topic of increasing interest. The Final Programmatic Environmental Impact Statement for the Clean Coal Technology Demonstration Program projected that with full implementation of those repowering CCTs that would be most effective at reducing CO2 emissions (Pressurized Fluidized Bed and Coal Gasification Fuel Cell technologies), the national fossil-fuel Co2 emissions by the year 2010 would be roughly 90% of the emissions that would occur with no implementation of any CCTs by the same date. It is the purpose of this paper to examine the global effect of such a reduction in greenhouse gas emissions, and to compare that effect with effects of other strategies for reducing global greenhouse gas emissions

    2006-11-27

    Effects of adenoviral therapy and reduced apoptosis on immune response were investigated in a rat liver transplantation model after prolonged ischemia-reperfusion. Liver donors were treated i.v. either with an adenoviral construct, expressing bcl-2, green-fluorescent-protein, or doxycyclin. Intrahepatic apoptosis was assessed by terminal transferase dUTP nick end labeling assay. The intrahepatic presence of CD4, CD8a, CD163, immunoglobulin (Ig)beta, tumor necrosis factor (TNF)-alpha and myeloperoxidase (MPO) was quantified by realtime polymerase chain reaction at 24 hours and seven days after transplantation. Bcl-2 expression abrogated the TNF-alpha elevation and reduced apoptosis of hepatocytes and sinusoidal endothelial cells as compared to advCMV green fluorescent protein. No effects on CD4, CD8a, CD163 and MPO expression were noticed in bcl-2 pretreated livers, whereas Igbeta was slightly enhanced compared to controls. Adenoviral infected liver grafts trigger an immune response but reduced apoptosis resulted in down-regulation of TNF-alpha. Thus, bcl-2 transfer might simultaneously reduce graft ischemia reperfusion injury and immunogenicity. PMID:17130789

  16. Rosalie Wolf Memorial Lecture: Reconsidering assumptions regarding men as elder abuse perpetrators and as elder abuse victims.

    Kosberg, Jordan I

    2014-01-01

    From research findings and practice experiences, it is concluded that abuse of older men is especially invisible and underreported, compared to abuse of older women. It is proposed that attention should be directed not to gender, but to those conditions in different countries and cultures leading to abuse of both older men and women, including (but not limited to) economic problems, few alternatives to family care of the elderly, violence, changing characteristics of the family, ageism, and sexism. Advocates for the prevention of elder abuse should work together in combating, reducing, and eliminating the problem of elder abuse of both older men and older women. PMID:24779537

  20. The Potential Of Fuel Cells To Reduce Energy Demands And Pollution From The UK Transport Sector

    Adams, Victor W.

    1998-01-01

    Atmospheric carbon dioxide and pollution due to the burning of fossil fuels is increasing. Many scientists attribute global warming to the rising levels of carbon dioxide and other pollutants, some of which also pose risks to health. These can be reduced by the more efficient use of conventional fuels and the development of non-polluting energy resources. Fuel cells offer a highly efficient and low polluting method of generating electricity, and are under development for both the power genera...

  1. [Experiences from two HIV prevention projects among drug abusers in Oslo. Is methadone maintenance treatment useful?].

    Skogstad, M

    1990-06-10

    Experience from two HIV-preventive projects among drug abusers in Oslo, Norway, shows that HIV-positive drug abusers carry on their drug abuse independent of visits to residential drug-free treatment or prison. HIV-positive former drug abusers show a tendency to relapse to drug abuse. In terms of HIV-prevention among drug abusers it is important to reduce injection of drugs among HIV-positive drug abusers. Thus, methadone maintenance programmes should be considered in HIV-prevention in Norway. PMID:2363170

    Piperlongumine (PLM) is a natural product from the plant Piper longum that inhibits platelet aggregation, atherosclerosis plaque formation, and tumor cell growth. It has potential value in immunomodulation and the management of autoimmune diseases. In this study, we investigated the role of PLM in regulating the differentiation and maturation of dendritic cells (DCs), a critical regulator of immune tolerance, and evaluated its clinical effects in a rheumatoid arthritis mouse model. We found that PLM treatment reduced LPS-induced murine bone marrow-derived DC maturation, characterized by reduced expression of CD80/86, secretion of MCP-1, IL-12p70, IL-6, TNFα, IFN-γ, and IL-23, and reduced alloproliferation of T cells; however, PLM does not affect cell differentiation. Furthermore, PLM reduced intracellular reactive oxygen species (ROS) production by DCs and inhibited the activation of p38, JNK, NF-κB, and PI3K/Akt signaling pathways. Conversely, PLM increased the expression of GSTP1 and carbonyl reductase 1, two enzymes that counteract ROS effects. ROS inhibition by exogenous N-acetyl-l-cysteine suppressed DC maturation. PLM treatment improved the severity of arthritis and reduced in vivo splenic DC maturation, collagen-specific CD4(+) T cell responses, and ROS production in mice with collagen-induced arthritis. Taken together, these results suggest that PLM inhibits DC maturation by reducing intracellular ROS production and has potential as a therapeutic agent for rheumatoid arthritis. PMID:27183580

  3. Potential cost-effectiveness of schistosomiasis treatment for reducing HIV transmission in Africa--the case of Zimbabwean women.

    Martial L Ndeffo Mbah

    Full Text Available BACKGROUND: Epidemiological data from Zimbabwe suggests that genital infection with Schistosoma haematobium may increase the risk of HIV infection in young women. Therefore, the treatment of Schistosoma haematobium with praziquantel could be a potential strategy for reducing HIV infection. Here we assess the potential cost-effectiveness of praziquantel as a novel intervention strategy against HIV infection. METHODS: We developed a mathematical model of female genital schistosomiasis (FGS and HIV infections in Zimbabwe that we fitted to cross-sectional data of FGS and HIV prevalence of 1999. We validated our epidemic projections using antenatal clinic data on HIV prevalence. We simulated annual praziquantel administration to school-age children. We then used these model predictions to perform a cost-effectiveness analysis of annual administration of praziquantel as a potential measure to reduce the burden of HIV in sub-Saharan Africa. FINDINGS: We showed that for a variation of efficacy between 30-70% of mass praziquantel administration for reducing the enhanced risk of HIV transmission per sexual act due to FGS, annual administration of praziquantel to school-age children in Zimbabwe could result in net savings of US$16-101 million compared with no mass treatment of schistosomiasis over a ten-year period. For a variation in efficacy between 30-70% of mass praziquantel administration for reducing the acquisition of FGS, annual administration of praziquantel to school-age children could result in net savings of US$36-92 million over a ten-year period. CONCLUSIONS: In addition to reducing schistosomiasis burden, mass praziquantel administration may be a highly cost-effective way of reducing HIV infections in sub-Saharan Africa. Program costs per case of HIV averted are similar to, and under some conditions much better than, other interventions that are currently implemented in Africa to reduce HIV transmission. As a cost-saving strategy, mass

  4. Reducing potential damages by freshet abatement in hydropower lakes. An argument for financing hydropower projects

    Dam reservoirs with significant water volumes (storage coefficients exceeding 8-10%) cause diminishing of the maximum flow downstream, especially due to the aleatory variation of the initial water level in the reservoir. Depending on the flow reduction in the dam, a methodology for determining the flow for the whole water course downstream is proposed, taking into account various potential combinations for flood generation in the catchment area. Differences between potential damages caused by floods in case of natural conditions versus those occurring in case of engineered zones result in important public financial benefits, amounting up to around 30% of the investments required for dam construction. For instance, in the case of hydropower lake Dragan on the Crisul Repede River the damages diminished down to about 50% for downstream watercourse. (authors)

    Child abuse is harm to, or neglect of, a child by another person, whether adult or child. Child abuse happens in all cultural, ethnic, and income groups. Child abuse can be physical, emotional - verbal, sexual or through neglect. Abuse may cause serious injury to the child and may even result in death. A problem that is only beginning to come into light in India rape, sexual abuse, and sexual harassment are worldwide issues of gender violence. There is very little research done in this area i...

  6. Inhalant Abuse and Dextromethorphan.

    Storck, Michael; Black, Laura; Liddell, Morgan

    2016-07-01

    Inhalant abuse is the intentional inhalation of a volatile substance for the purpose of achieving an altered mental state. As an important, yet underrecognized form of substance abuse, inhalant abuse crosses all demographic, ethnic, and socioeconomic boundaries, causing significant morbidity and mortality in school-aged and older children. This review presents current perspectives on epidemiology, detection, and clinical challenges of inhalant abuse and offers advice regarding the medical and mental health providers' roles in the prevention and management of this substance abuse problem. Also discussed is the misuse of a specific "over-the-counter" dissociative, dextromethorphan. PMID:27338970

  8. The potential for reducing the cost of a heavy ion accelerator for ICF: Final report

    Monsler, M.J.

    1987-02-25

    This study was initiated to identify the high leverage areas for reducing the cost of a 10 MJ heavy ion beam driver for a high gain target development facility. Our efforts to innovate to reach affordable cost have been mostly successful, in that it looks like the $500 M range may indeed be possible. We conclude that heavy ion beams do have substantial promise for an inertial fusion driver. However, the pace of R and D would have to be substantially increased to realize this promise on a timescale necessary for a High Gain Test Facility.

  10. Reduced greenhouse gas mitigation potential of no-tillage soils through earthworm activity

    Lubbers, Ingrid M.; Kees Jan Van Groenigen; Lijbert Brussaard; Jan Willem van Groenigen

    2015-01-01

    Concerns about rising greenhouse gas (GHG) concentrations have spurred the promotion of no-tillage practices as a means to stimulate carbon storage and reduce CO2 emissions in agro-ecosystems. Recent research has ignited debate about the effect of earthworms on the GHG balance of soil. It is unclear how earthworms interact with soil management practices, making long-term predictions on their effect in agro-ecosystems problematic. Here we show, in a unique two-year experiment, that earthworm p...
