Cannabis withdrawal symptoms might have clinical importance

Certain withdrawal symptoms are more correlated to risk of relapse in cannabis users

2012-09-27
(Press-News.org) Cannabis users have a greater chance of relapse to cannabis use when they experience certain withdrawal symptoms, according to research published Sep. 26 in the open access journal PLOS ONE led by David Allsop of the National Cannabis Prevention and Information Centre (NCPIC) at the University of New South Wales.

The authors tested a group of dependent cannabis users over a two week period of abstinence for impairment related to their withdrawal symptoms. Findings were correlated with the probability of relapse to cannabis use during the abstinence period, and the level of use one month later.

They found that in more dependent users, certain withdrawal symptoms, such as physical tension, sleep problems, anxiety, depression, mood swings and loss of appetite, were more strongly associated with relapse than other symptoms, such as hot flashes, fatigue, or night sweats. Participants with greater dependence before the abstinence attempt reported more severe impairment from the withdrawal. Participants with greater impairment from cannabis withdrawal consumed more cannabis during the month following the abstinence attempt.

If these results extend to treatment seeking cannabis users seeking treatment for withdrawal, the research may help improve counseling and treatment strategies for those looking for support.

"Tailoring treatments to target withdrawal symptoms contributing to functional impairment during a quit attempt may improve treatment outcomes" says Allsop.

First evidence of fetal DNA persisting in human brain tissue

First evidence of fetal DNA persisting in human brain tissue
2012-09-27
Small portions of male DNA, most likely left over in a mother's body by a male fetus can be detected in the maternal brain relatively frequently, according to a report published Sep. 26 in the open access journal PLOS ONE by William Chan of Fred Hutchinson Cancer Research Center and his colleagues. The process, called fetal 'microchimerism (Mc)', is common in other tissues such as blood, but this is the first evidence of male Mc in the human female brain. Microchimerism can be both beneficial and harmful to maternal health, since it is associated with processes such ...

Viewing gender-specific objects influences perception of gender identity

Viewing gender-specific objects influences perception of gender identity

Spending too much time looking at high heels may influence how a viewer perceives the gender of an androgynous face, according to new research published Sep. 26 in the open access journal PLOS ONE by Amir Homayoun Javadi of Technische Universität, Dresden and his colleagues. The study sheds new light on how the objects surrounding us may influence our perceptions of gender. The authors found that when people view objects highly associated with one gender, like high heels for women or electric shavers for men, for a short period of time and are then asked to identify the ...

Psychology of equine performance and the biology behind laminitis

Psychology of equine performance and the biology behind laminitis
2012-09-27
Achieving the best performance from a horse is the goal of not just professional riders, but also the millions of amateur and hobby riders all over the world. A new article published in BioMed Central's open access journal BMC Veterinary Research looks at the issues surrounding training, competition environment and practices, and how the psychology of horse mood, emotion and temperament can be used to enhance performance. A sister article looks at the devastating disease laminitis, and finds that the anti-inflammatory protein apolipoprotein A-IV (APOA-IV) is raised in chronic ...

Scientists make old muscles young again in attempt to combat aging

2012-09-27
An international team of scientists have identified for the first time a key factor responsible for declining muscle repair during ageing, and discovered how to halt the process in mice with a common drug. Although an early study, the findings provide clues as to how muscles lose mass with age, which can result in weakness that affects mobility and may cause falls. The study, to be published in the journal Nature, involved researchers from King's College London, Harvard University and Massachusetts General Hospital. The study looked at stem cells found inside muscle ...

TB drug could reduce mortality for MDR-TB and XDR-TB cases

2012-09-27
Results from an observational study evaluating a new anti-TB drug have found that the treatment can improve outcomes and reduce mortality among patients with both MDR-TB and XDR-TB. The research, published online ahead of print today (27 September 2012) in the European Respiratory Journal, suggests a drug called delamanid could have a public health benefit for MDR-TB and also for XDR-TB, as few effective treatment options are currently available. Over the past two decades, multidrug-resistant TB (MDR-TB) has emerged as a significant public health threat, with strains ...

Salt marsh carbon may play role in slowing climate warming, study shows

2012-09-27
A warming climate and rising seas will enable salt marshes to more rapidly capture and remove carbon dioxide from the atmosphere, possibly playing a role in slowing the rate of climate change, according to a new study led by a University of Virginia environmental scientist and published in the Sept. 27 issue of the journal Nature. Carbon dioxide is the predominant so-called "greenhouse gas" that acts as sort of an atmospheric blanket, trapping the Earth's heat. Over time, an abundance of carbon dioxide can change the global climate, according to generally accepted scientific ...

WSU study finds dioxin causes disease and reproductive problems across generations

2012-09-27
PULLMAN, Wash.—Since the 1960s, when the defoliant Agent Orange was widely used in Vietnam, military, industry and environmental groups have debated the toxicity of its main ingredient, the chemical dioxin, and how it should be regulated. But even if all the dioxin were eliminated from the planet, Washington State University researchers say its legacy will live on in the way it turns genes on and off in the descendants of people exposed over the past half century. Writing in the journal PLoS ONE, biologist Michael Skinner and members of his lab say dioxin administered ...

Inadequate cellular rest may explain effects of aging on muscles

2012-09-27
Is aging inevitable? What factors make older tissues in the human body less able to maintain and repair themselves, as in the weakening and shrinkage of aging muscles in humans? A new study from Massachusetts General Hospital (MGH) investigators and collaborators at King's College London describes the mechanism behind impaired muscle repair during aging and a strategy that may help rejuvenate aging tissue by manipulating the environment in which muscle stem cells reside. The report will appear in the journal Nature and has received advance online release. Rare muscle ...
