Specific trauma experiences contribute to women's alcohol use, differs by race

Researchers examined data from the Missouri Adolescen t Female Twins Study: the mean age of the 3,787 women at time of interview was 24.5 years; 85.4 percent were EA, 14.6 percent AA. Trauma exposures were defined as sexual abuse (SA), physical abuse (PA), witnessing another person being killed or injured, experiencing an accident, or experiencing a disaster. Trauma exposure was examined as a predictor of alcohol initiation, transition to the first AUD symptom, and transition to an AUD diagnosis -- while also considering other substance involvement , parental characteristics, and commonly co-occurring psychiatric disorders. Results showed that trauma experiences were important contributors to all stages of alcohol involvement in EA women only, with different trauma types conferring risk for each stage of alcohol involvement. For example, in EA women SA was associated with alcohol initiation prior to the age of 14; PA predicted the transition from initiation to the first AUD symp...

Identifying ecstasy's dangerous path

Siddharth Chandra, director of MSU's Asian Studies Center, has developed a methodology based on the wholesale prices of Ecstasy in 59 cities, identifying probable city-to-city links for the transit of the drug. He used data published by the National Drug Intelligence C enter of the U.S. Department of Justice from 2002 to 2011, which field intelligence officers and local, regional and federal law enforcement sources collected through drug arrests and investigations. "NDIC hasn't highlighted the Carolinas as an area of activity but our price data suggest there's a lot going on there," he said. "Prices are probably one of the most important economic phenomena because they carry information about the movement of goods." Never before implemented to study drug-trafficking patterns, Chandra's methodology is simple. Drugs are inferred to flow from the city with the lower price to the city with the higher price. If cities are connected as source and de...

If legalizing pot, consider health, not profits, analysis says

The policy analysis by researchers at UC San Francisco is intended as a roadmap to help prevent a legalized marijuana industry from becoming a new version of the tobacco or alcohol industries, replete with aggressive marketing and political strategies to protect their economic interests. Policymakers Could Learn from Alcohol, Tobacco The paper draws upon historical accounts from tobacco and alcohol control to conclude that policymakers could learn from those regulatory lessons to shape marijuana laws that would minimize consumption and protect the public. In such a process, marijuana would be treated like tobacco, not alcohol, and would be subject to a robust, demand reduction program, using evidence-based strategies from tobacco control. "Current state marijuana laws and pending legalization initiatives are modeled on U.S. alcohol policies, which prioritize commercialization and tax revenue generation at the expense of public health," said lead author and UCSF polic...

Alcohol shown to act in same way as rapid antidepressants

Image
Regardless of its findings, this examine does by no means counsel that alcohol will be thought to be an efficient therapy for despair. Credit score: © Photographee.eu / Fotolia Can having a couple of drinks assist individuals with medical despair really feel higher? Sure. Not less than by way of biochemistry. In a examine printed within the present challenge of the journal  Nature Communications , researchers discovered that alcohol produces the identical neural and molecular adjustments as medicine which have confirmed to be quickly efficient antidepressants. "Due to the excessive comorbidity between main depressive dysfunction and alcoholism there's the well known self-medication speculation, suggesting that depressed people might flip to consuming as a method to deal with their despair," stated the examine's principal investigator, Kimberly Raab-Graham, Ph.D., affiliate professor of physiology and pharmacolog...

Cocaine accumulation in fish eyes

Cocaine distribution in five-day-old zebrafish larvae uncovered to 50 µM cocaine for eight hours. A) Optical picture of stained coronal tissue part, B) overlay of A with MALDI picture. C) and D) Saggital part of head with eye (backside proper). Within the MALDI photos, blue = low concentrations, yellow-red = excessive co ncentrations of cocaine . By far the best concentrations have been discovered within the eyes. Credit score: Picture courtesy of EAWAG: Swiss Federal Institute of Aquatic Science and Know-how A examine by Eawag and Zurich College researchers utilizing a brand new imaging methodology has revealed that, surprisingly, cocaine accumulates within the eyes of zebrafish. The findings point out that chemical substances -- particularly psychoactive medication -- have to be assessed fairly otherwise with waterborne publicity than, for instance, when pharmaceutical substances are examined in mice. Specifically, the uptake mechani...

More than half of persons with Alzheimer's disease aged 90 years or more use psychotropic drugs

56% of persons aged 90 years or more with Alzheimer's disease use psychotropic drugs whereas the same figure was 48% among younger persons with Alzheimer's disease and 38% among those aged 90 years or more but without Alzheimer's disease. Psychotropic drugs include antipsychotics, antidepressants and benzodiazepines and related drugs which are used for anxiety and insomnia in short-term treatment. On the contrary, persons aged 90 years or more with Alzheimer's disease used less frequently antidementia drugs (63%) when compared with younger persons with the same disease (72%). Psychotropic drugs are related to significant risk of adverse effects among older users and for this reason, very frequent use of these drugs among the oldest persons is concerning. The need and safety of drug use should be regularly assessed. Drug use was studied within MEDALZ study cohort within six months after the diagnoses of Alzheimer's disease in Finland. Data for 67,215 persons...

New system can detect cocaine at low concentrations

The method combines the use of gated mesoporous silica nanoparticle s and SERS spectroscopy, a signal amplification system that uses gold nanoparticles to detect very low concentrations of the substances being analysed. In the lab, it allowed them to reach nanomolar detection levels for cocaine and 30 copies of genomic DNA/μL in the case of mycoplasma. Developed by researchers at the Universitat Politècnica de València (UPV), CICbiomaGUNE and CIBER-BBN, of the Carlos III Health Institute, the study has been published in  Chemistry-A European Journal  with the title, "Surface Enhanced Raman Scattering and Gated Materials for Sensing Applications." In it they outline the need to detect these two substances: "Cocaine is an alkaloid obtained from the leaves of the coca plant, which is extensively used in developed countries as an illegal recreational drug. Although cocaine production and distribution are restricted and illegal in most contexts, it is a powerful nervous...
