The long-term effects of teasing or harassment by their peers on pre-adolescent children – specifically, depression and anxiety – are related, in part, to the level of victimization at the end of fourth grade, as well as to how much that harassment increased or decreased between fourth and sixth grade, according to a study published in the September/October issue of the journal Child Development.
The study, by researchers from North Dakota State University and Arizona State
Despite the government’s £1bn commitment to increase the use of information technology in schools, few teachers make full use of computers in the classroom, according to ESRC funded research. The findings of the four-year project at the University of Bristol confirm recent reports by Ofsted and OECD, which found the use of ICT in schools was ‘sporadic’ and ‘disappointing’ in the UK and internationally. The ESRC study reveals that many teachers fear that computers would interfere with ‘genuine’
Study points to importance of pathway in cancer progression
The cancer gene MYC is among the most commonly overexpressed oncogenes in human cancers. Most human cancers demonstrate high levels of MYC or its biological partners, including those of the breast, ovaries, lung, prostate, and skin, as well as leukemias and lymphomas. MYC is a regulator of other genes–a transcription factor–and scientists have been working for more than two decades to identify its target genes in order
Study suggests chronic infections may create autoimmune response
New research finds the human immune system has foregone evolutionary changes that would allow it to produce better antibodies in less time because the improved antibodies would be far more likely to attack the body’s own tissues. The Rice University study finds the immune system has evolved a near-perfect balance for producing antibodies that are both effective against pathogens and unlikely to cause autoimmune
Landmark data from the PROactive Study, presented today at the 41st meeting of the European Association for the Study of Diabetes (EASD) demonstrated that ACTOS® (pioglitazone HCl) significantly reduced the combined risk of heart attacks, strokes and death by 16% in high-risk patients with type 2 diabetes.
“The PROactive study is the first in the world to prospectively show that a specific oral glucose lowering medication, namely pioglitazone, can significantly improve cardiov
Yale School of Medicine researchers published a report this month in the Archives of General Psychiatry that highlights the interplay of two brain signaling systems, glutamate and dopamine, in psychosis and cognitive function.
The study helps resolve a long-standing research debate between the “dopamine hypothesis” and the “glutamate hypothesis” or “PCP Model,” said John Krystal, M.D., professor, deputy chair for research in the Department of Psychiatry, and lead author of th
In a study published in The American Journal of Gastroenterology, researchers found that budesonide capsules are an effective treatment to prolong and maintain the period of remission of Crohn’s Disease. Previous studies have demonstrated that budesonide is effective for inducing remission of Crohn’s disease.
Four double-blind, placebo-controlled trials were conducted with identical protocols in which patients with Crohn’s Disease, and medically induced remission,
Finding may significantly broaden understanding of how the brain selects and retains information
By examining how sounds are registered during the process of learning, UC Irvine neurobiologists have discovered a neural coding mechanism that the brain relies upon to register the intensity of memories based on the importance of the experience.
While neurobiologists have long hypothesized this type of neural coding, the study presents the first evidence that a “memory co
In a first study of its kind, researchers at the Mailman School of Public Health assessed the ability and willingness of healthcare workers to report to work in the event of disasters involving weapons of mass destruction or virulent infectious disease outbreaks. Eighty-seven percent of healthcare workers from 47 facilities in and around New York City, indicate that they would be able to report for work in the event of a mass casualty incident and 81% would be able to go to work if there was an e
Two common weight loss supplements promoted as ephedra-free and safe for dieters caused increased heart rate among healthy people, and could have harmful health effects in some people, according to a study by UCSF scientists. Their placebo-controlled clinical study is the first to examine the pharmacological effects of these re-formulated dietary supplements.
The research examined the effects on blood pressure and heart rate of two dietary supplements containing bitter orange e
Diet effective with no limits on portion size
A low-fat, plant-based diet is more effective at helping women lose weight and improve insulin sensitivity than an omnivorous diet, shows a new study appearing in the September issue of The American Journal of Medicine. The study, involving 59 overweight, postmenopausal women, was conducted by Neal D. Barnard, M.D., president of the Physicians Committee for Responsible Medicine (PCRM), together with colleagues at Georgetown Universi
Clioquinol, an antibiotic that was banned for internal use in the United States in 1971 but is still used in topical applications, appears to block the genetic action of Huntington’s disease in mice and in cell culture, according to a study reported by San Francisco VA Medical Center (SFVAMC) researchers.
The study, led by principal investigator Stephen M. Massa, MD, PhD, a neurologist at SFVAMC, was reported in the August 16, 2005 issue of Proceedings of the National Acade
A new study finds the number of women getting routine screening mammography may be less than previously reported. The study, published in the October 15, 2005 issue of CANCER, a peer-reviewed journal of the American Cancer Society, finds as many as one in three women have never had a mammogram or have not had one in more than two years, and that many women have one or two mammograms then fail to return for regular screenings.
While screening mammography has been credited with sig
Women who suffer heart attacks wait longer to be assessed, admitted and receive treatment than men with the same condition, according to a paper in the latest Journal of Advanced Nursing.
890 patients admitted to coronary care units via casualty departments in six major teaching hospitals in Dublin were studied in detail by a team led by Dr Sharon O’Donnell from the City’s Trinity College.
The study of 613 men and 277 women shows that: On average, wo
Several nuclear receptor proteins appear to overlap in their ability to exert anti-inflammatory effects, according to new research by scientists at the University of California, San Diego (UCSD). Nuclear receptors are important drug targets for a number of diseases, for example, glucocorticoid receptors for asthma and arthritis. But use of drugs targeting these receptors is sometimes limited by unwelcome side effects. The new findings may suggest a way to overcome this obstacle.

NSW Special Minister of State, John Della Bosca, today announced the results of new research which shows an alarming number of children are being put at risk through the improper use of seat belts and child restraints.
The research, undertaken by the Prince of Wales Medical Research Institute with the Children’s Hospital at Westmead and the Sydney Children’s Hospital, examined crash and injury data for children aged 2-8 years who were in motor vehicle accidents.
