(Press-News.org) A population-based case-control study of the rare but devastating neurological disease amyotrophic lateral sclerosis (ALS) has shown that the risk of such disease is increased among smokers, as has been shown previously. However, surprisingly, the risk of ALS was found to be markedly lower among consumers of alcohol than among abstainers.
Forum reviewers thought that this was a well-done and important paper, as it is a population-based analysis, with almost 500 cases of ALS, a very large number of cases for this rare disease. They were especially struck by the magnitude of the difference in risk of ALS between alcohol consumers and never drinkers: the risk among drinkers was about one half that of non-drinkers. Said one reviewer: "The results in this study are astonishing in this mysterious disease. One should expect that alcohol, as a toxic agent, rather should contribute to the development of ALS than to prevent it. The lower risk among drinkers compared with non-drinkers is remarkable"
Forum reviewers cautioned that the results of this paper should not be used to prompt people to consume alcohol just to prevent ALS, as it is such a rare disease. However, this paper presents important data that could help scientists understand the etiology of ALS and perhaps other more common diseases.

CLEMSON — Clemson researchers are taking common materials to uncommon places by transforming easily obtainable and affordable materials into fiber. Their findings are published in Nature Photonics, the world's top journal focused on light-based technologies.
"We have used a highly purified version of beach sand (silica) for fiber for the last 40 years," said John Ballato, director of the Center for Optical Materials Science and Engineering Technologies at Clemson University. "As a matter of fact, the 2009 Nobel Prize in Physics was awarded for the development of silica ...
(Boston) - Researchers at Boston University School of Medicine (BUSM) have been part of a multicenter observational study called TRACS (Transthyretin Amyloidosis Cardiac Study) to help determine the health significance of a particular gene mutation which is commonly found in Black Americans.
The gene, transthyretin (TTR) and the mutation V122I, is seen in about four percent of African Americans or roughly 1.5 million people. The mutation is strongly associated with a condition called cardiac amyloidosis - a disorder where the abnormally mutated TTR protein deposits in ...
Competitiveness amongst NBA teams is more constant throughout seasons than during the ACB basketball league (Spain), which also falls after every Olympic Games. According to a study from the University of Las Palmas de Gran Canaria, the differences could be attributed to economic and organisational reasons: in the NBA there is just one division, there is a salary cap and the weakest teams have access to good players.
The National Basketball Association (NBA) of North America and the Association of Basketball Clubs (ACB) of Spain are the best and most competitive basketball ...
Tel Aviv University researchers recently uncovered a seal, measuring 15 millimetres (about a half-inch) in diameter, which depicts a human figure next to a lion at the archaeological site of Beth Shemesh, located between the Biblical cities of Zorah and Eshtaol, where Samson was born, flourished, and finally buried, according to the book of Judges. The scene engraved on the seal, the time period, and the location of the discovery all point to a probable reference to the story of Samson, the legendary heroic figure whose adventures famously included a victory in hand-to-paw ...
WASHINGTON, August 13, 2012─On August 13, AERA filed an amicus curiae brief in the U.S. Supreme Court case of Fisher v. University of Texas at Austin. The association is joined by seven other scientific societies in urging the Court to consider an overwhelming body of scientific evidence relevant to the case. "AERA has a fundamental interest in the accurate presentation of social science research on these important questions of law. Quite simply, we have a responsibility to enable the Court to make its determinations based on the best scientific evidence available," ...
New Rochelle, NY, August 13, 2012—Even after being frozen for 18 years, human embryos can be thawed, grown in the laboratory, and successfully induced to produce human embryonic stem (ES) cells, which represent a valuable resource for drug screening and medical research. Prolonged embryonic cryopreservation as an alternative source of ES cells is the focus of an article in BioResearch Open Access, a new bimonthly peer-reviewed open access journal from Mary Ann Liebert, Inc. The article is available free online at the BioResearch Open Access website.

The second of two studies on latrepirdine, recently published in Molecular Psychiatry, demonstrates new potential for the compound in the treatment of Alzheimer's disease, Parkinson's disease, sleep disorders, and other neurodegenerative conditions. An international team led by Mount Sinai School of Medicine scientists found that latrepiridine, known commercially as Dimebon, reduced the level of at least two neurodegeneration-related proteins in mice.
Latrepirdine was initially sold as an antihistamine in Russia, following its approval for use there in 1983. In the 1990s, ...
PHILADELPHIA -- A popular class of diabetes drugs increases patients' risk of bladder cancer, according to a new study published online this month in the Journal of the National Cancer Institute. Researchers from the Perelman School of Medicine at the University of Pennsylvania found that patients taking thiazolidinedione (TZDs) drugs – which account for up to 20 percent of the drugs prescribed to diabetics in the United States -- are two to three times more likely to develop bladder cancer than those who took a sulfonylurea drug, another common class of medications for ...
Researchers at Mount Sinai School of Medicine may have discovered why certain drugs to treat schizophrenia are ineffective in some patients. Published online in Nature Neuroscience, the research will pave the way for a new class of drugs to help treat this devastating mental illness, which impacts one percent of the world's population, 30 percent of whom do not respond to currently available treatments.
A team of researchers at Mount Sinai School of Medicine set out to discover what epigenetic factors, or external factors that influence gene expression, are involved in ...
Scientists have identified new genetic alterations underlying a high-risk subtype of the most common childhood cancer that could be effectively targeted with existing leukemia therapies.
The study focused on a subtype of acute lymphoblastic leukemia (ALL) known as Philadelphia chromosome-like ALL (Ph-like ALL). This subgroup accounts for as much as 15 percent of childhood ALL that is associated with a high risk of relapse and a poor outcome. The genetic changes driving the disease were previously unknown for about half of all patients with Ph-like ALL. The work identified ...
