Switching Off Hunger Hormone Affects Desire To Drink

A Faculty of 1000 evaluation examines how a stomach-produced hormone that influences the desire to eat and consume alcohol could be switched off to control drinking problems. The study, carried out by Jerlhag et al. at the University of Gothenburg in Sweden, showed that the hormone ghrelin, typically released by the stomach and known to promote appetite and therefore the intake of food, also influences the consumption of alcohol. The results, published in The Proceedings of the National Academy of Sciences of the USA, showed that mice injected with ghrelin and then given the choice of alcohol or water to drink, were more likely to choose alcohol. At the same time, mice treated with ghrelin antagonists, as well as knockout mice (mice with the hormone's receptor removed), proved resistant to the effects of alcohol.

UB Neurobiologist Studying The Addictive Effects Of Caffeine On Children

Caffeine is a stimulant drug, although legal, and adults use it widely to perk themselves up: Being "addicted" to caffeine is considered perfectly normal. But how strong is caffeine's appeal in young people who consume an abundance of soft drinks? What impact does acute and chronic caffeine consumption have on their blood pressure, heart rate and hand tremor? Furthermore, does consuming caffeinated drinks during adolescence contribute to later use of legal or illicit drugs? Jennifer L. Temple, PhD, a neurobiologist, assistant professor of exercise and nutrition sciences at the University at Buffalo and director of its Nutrition and Health Research Laboratory, is looking for answers to these three questions through a 4-year, $800, 000 study funded by the National Institutes of Health.

New Mechanism Underlying Cocaine Addiction Discovered

Researchers have identified a key epigenetic mechanism in the brain that helps explain cocaine's addictiveness, according to research funded by the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health. The study, published in the January issue of the journal Science, shows how cocaine affects an epigenetic process (a process capable of influencing gene expression without changing a gene's sequence) called histone methylation. These epigenetic changes in the brain's pleasure circuits, which are also the first impacted by chronic cocaine exposure, likely contribute to an acquired preference for cocaine. "This fundamental discovery advances our understanding of how cocaine addiction works, " said NIDA Director Dr.

Medical Marijuana Incorporated Applauds The State Of New Jersey For Passing The Compassionate Use Medical Marijuana Act

Words Used To Describe Substance-Use Patients Can Alter Attitudes, Contribute To Stigma

Changing the words used to describe someone struggling with alcoholism or drug addiction may significantly alter the attitudes of health care professionals, even those who specialize in addiction treatment. Massachusetts General Hospital (MGH) researchers have found that health professionals' answers to survey questions about a hypothetical patient varied depending on whether he was described as a "substance abuser" or as "having a substance use disorder." Their study will appear in the International Journal of Drug Policy and has been released online. "We found that referring to someone with the 'abuser' terminology evokes more punitive attitudes than does describing that person's situation in exactly the same words except for using 'disorder' terminology, " says John F.

Study Reveals The Role Played By Cocaine In Sudden Death

Forensic pathologists have shown that over three per cent of all sudden deaths in south-west Spain are related to the use of cocaine. They believe their findings can be extrapolated to much of the rest of Europe, indicating that cocaine use is a growing public health problem in Europe and that there is no such thing as "safe" recreational use of small amounts of the drug. The study published in Europe's leading cardiology journal, the European Heart Journal [1] on 13 January 2010, carefully investigated all the circumstances surrounding a consecutive series of sudden deaths between 2003 and 2006. During post-mortems the pathologists tested blood and urine for traces of toxic substances, and studied the organs, focusing on the cardiovascular system and toxicological analysis;

New Jersey To Legalize Medical Marijuana

The New York Times : "The New Jersey Legislature approved a measure on Monday that would make the state the 14th in the nation, but one of the few on the East Coast, to legalize the use of marijuana to help patients with chronic illnesses. The measure - which would allow patients diagnosed with severe illnesses like cancer, AIDS, Lou Gehrig's disease, muscular dystrophy and multiple sclerosis to have access to marijuana grown and distributed through state-monitored dispensaries - was passed by the General Assembly and State Senate on the final day of the legislative session" (Kocieniewski, 1/11). The Philadelphia Inquirer : "Last February, the state Senate approved a medical-marijuana bill with bipartisan support.

Drinkaware Response To Health Select Committee Report On Alcohol Policy, UK

Reacting to a report from the Health Select Committee on Alcohol, which calls for an overhaul of the Government's alcohol policy, Chris Sorek, Chief Executive of alcohol awareness charity Drinkaware, says: "Binge drinking is one of the biggest blights on today's society and it's imperative that action is taken to minimise the grim effects of alcohol misuse. The financial and social impact of alcohol misuse affects everyone, whether they drink alcohol or not. "No one solution on its own will tackle the British drinking culture - a range of measures are needed to combat the harm caused by alcohol misuse. Education plays a critical role - all too often people are drinking without knowing about units, health risks or sometimes even the strength of their favourite drink.

Alcohol Metabolism Enzyme Repaired By Molecule

An experimental compound repaired a defective alcohol metabolism enzyme that affects an estimated 1 billion people worldwide, according to research supported by the National Institute on Alcohol Abuse and Alcoholism (NIAAA). The findings, published Jan. 10, 2010 in the advance online edition of Nature Structural and Molecular Biology, suggest the possibility of a treatment to reduce the health problems associated with the enzyme defect. "This intriguing finding could have broad public health implications, " said NIAAA Acting Director Kenneth R. Warren, Ph.D. "We look forward to further research aimed at translating these laboratory discoveries into possible treatments for people.
