After decades of public safety campaigns focused on drinking and driving, it may be time to focus on the seventh leading cause of injury-related death, according to Bureau of Occupational Health and Injury Prevention at New York State Department of Health and Columbia University scholars looking at New York State.
In a population of Congo Basin foragers called the Aka, 67% of men—but only 6% of women—use cannabis, and the practice seems to protect against infection with parasitic worms.
The large sex difference, which is also seen in tobacco use, might be a consequence, in part, of women's avoidance of potentially toxic substances during childbearing years.
The results provide evidence of a link between parasite infection and drug use, two of the developing world's great health problems, and they highlight the need for more research on the high rate of substance use in Aka men.
New recommendations offer insights on strategies for treating infants with seizures. In an Epilepsia report, child neurologists who are members of the International League Against Epilepsy note that intervening at the time of a febrile seizure does not alter the risk for subsequent epilepsy, and there is no evidence to support the use of antiepileptic drugs for simple febrile seizures. However, recurrent seizures warrant an urgent assessment, and a variety of antiepileptic drugs may benefit these patients. Unfortunately, there is no high level evidence to support the use of any one particular drug among those that are currently available for use in infants with seizures.
Like a dairy farmer tending to a herd of cows to produce milk, researchers are tending to colonies of the bacteria Escherichia coli (E. coli) to produce new forms of antibiotics -- including three that show promise in fighting drug-resistant bacteria.
The research, which will be published May 29 in the journal Science Advances, was led by Blaine A. Pfeifer, an associate professor of chemical and biological engineering in the University at Buffalo School of Engineering and Applied Sciences. His team included first author Guojian Zhang, Yi Li and Lei Fang, all in the Department of Chemical and Biological Engineering.
Singapore -- Scientists from A*STAR's Bioinformatics Institute (BII) have developed an analytical model and computational tool to rapidly and accurately predict the occurrence and locations of R-loop Forming Sequences (RLFSs) in any genome or artificial nucleic acid sequences. R-loops, which are three-stranded RNA and DNA hybrid structures, can be crucial to many normal biological processes and have also been associated with triggering mutations, DNA breaks and diseases. These hybrid structures provide intriguing possibilities for use as novel targets for diagnostics and treatment of diseases including cancer, autoimmune and neurodegenerative conditions.
Using a complex modeling program that helps analyze the physical dynamics of large, structurally complex protein molecules, a research team has made progress towards finding a weak spot in the architecture of a group of enzymes that are essential to antibiotic resistance in a number of bacteria.
In an article published in PLOS ONE, University of North Carolina at Charlotte senior biology major Jenna R. Brown and her faculty mentor, UNC Charlotte professor of bioinformatics and genomics Dennis R. Livesay, present an analysis of the four currently known protein structures of the class C beta-lactamase enzymes - molecular machines that have evolved to allow bacteria to dismantle a variety of antibiotic molecules, including third generation cephalosporins.
Some decisions arouse far more anxiety than others. Among the most anxiety-provoking are those that involve options with both positive and negative elements, such choosing to take a higher-paying job in a city far from family and friends, versus choosing to stay put with less pay.
MIT researchers have now identified a neural circuit that appears to underlie decision-making in this type of situation, which is known as approach-avoidance conflict. The findings could help researchers to discover new ways to treat psychiatric disorders that feature impaired decision-making, such as depression, schizophrenia, and borderline personality disorder.
The recent floods in Texas have caused some of the worst flooding since Hurricane Ike in 2008, causing the rainiest month in the state's history.
What lessons have been learned from Ike's devastation of the Galveston and Houston area, and how have they helped in the prediction of future such storms?
Researchers at the Institute for Computational Engineering and Sciences at the University of Texas at Austin have been studying computational models and simulations of hurricanes like Ike in order to predict the consequences of such natural disasters and better prepare the Texas Gulf Coast for their effects.
Bacteria and viruses have an obvious role in causing infectious diseases, but microbes have also been identified as the surprising cause of other illnesses, including cervical cancer (Human papilloma virus) and stomach ulcers (H. pylori bacteria).
A new study by University of Iowa microbiologists now suggests that bacteria may even be a cause of one of the most prevalent diseases of our time - Type 2 diabetes.
The research team led by Patrick Schlievert, PhD, professor and DEO of microbiology at the UI Carver College of Medicine, found that prolonged exposure to a toxin produced by Staphylococcus aureus (staph) bacteria causes rabbits to develop the hallmark symptoms of Type 2 diabetes, including insulin resistance, glucose intolerance, and systemic inflammation.
A long noncoding RNA (lncRNA), which might give an impact on tyrosine kinase-targeted leukemia therapy, was found to be expressed in a leukemia cell line. The function of the lncRNA CCDC26 is not fully understood; however, researchers found the mechanisms by which CCDC26 controls the receptor tyrosine kinase KIT expression. Recent transcriptomic studies have revealed the existence of numerous RNAs that are relatively long but not translated into proteins. Some of such lncRNAs are suggested to regulate the expression of other genes. Mutations or imbalances in the noncoding RNA repertoire within the body can therefore cause a variety of diseases such as cancer. However, the molecular functions of lncRNAs remain to be fully elucidated.
If you lived on one of Pluto's moons, you might have a hard time determining when, or from which direction, the sun will rise each day. Two of Pluto's moons, Nix and Hydra, wobble unpredictably, according to a new data analysis.
Beginning readers who focus on letter-sound relationships, or phonics, instead of trying to learn whole words, increase activity in the area of their brains best wired for reading, according to new Stanford research investigating how the brain responds to different types of reading instruction.
In other words, to develop reading skills, teaching students to sound out "C-A-T" sparks more optimal brain circuitry than instructing them to memorize the word "cat." And, the study found, these teaching-induced differences show up even on future encounters with the word.
A team of biologists and a mathematician have identified and characterized a network composed of 94 proteins that work together to regulate fat storage in yeast.
"Removal of any one of the proteins results in an increase in cellular fat content, which is analogous to obesity," says study coauthor Bader Al-Anzi, a research scientist at Caltech. The findings, detailed in the May issue of the journal PLOS Computational Biology, suggest that yeast could serve as a valuable test organism for studying human obesity.
