Calculating Electron Correlations in the Hydrogen Molecule
Need to understand the details of how a molecule is put together? Want to see the effects of the intricate dance that its electrons do to make a chemical bond? Try blowing a molecule to bits and calculating what happens to all the pieces. That’s the approach taken by an international group of collaborators from the University of California at Davis, universities in Spain and Belgium, and the Chemical Sciences Division o
Responding to a need among cardiologists for a practical textbook that brings together ESC Guidelines and best practice coupled with a strong clinical focus, the European Society of Cardiology (ESC) will publish its first textbook in cardiovascular medicine early next year. Entitled, The ESC Textbook of Cardiovascular Medicine, the book will be published 13 January 2006 (1).
According to ESC President Michal Tendera, “Education is central to ESC activities and with the publication of The E
Some of the country’s foremost experts on stroke are gathering at the University of Reading on Wednesday 14 December to discuss the latest research into stroke, which is the third biggest killer and the leading cause of disability in the UK.
A wide range of research areas will be discussed at the workshop, called ‘The Biology and Business of Stroke’. Speakers will consider the latest approaches to the diagnosis and management of stroke, such as the role of diet and medical drugs.
Discuss uses for diagnosing oral health problems
Cone beam computerized tomography (CBCT) increasingly has become the newest technology for orthodontists to use in diagnosing complicated oral health problems.
Reporting on four new CBCT systems in the December issue of the Journal of Orthodontics are J. Martin Palomo and Mark Hans from the department of orthodontics at the Case Western Reserve University School of Dental Medicine and C.H. Kau and S. Richmond from the de
New Saint Louis University study validates first questionnaire of its kind
A four-question screening tool can predict which older patients with appetite problems are likely to lose weight, placing them at greater risk of death, according to Saint Louis University research.
The questionnaire is called the SNAQ (pronounced snack), the Simplified Nutritional Appetite Questionnaire, and takes less than two minutes to answer.
“This tool tells us whether a poor appeti
In an analysis combining data from 13 studies, high intake of dietary fiber was not associated with reduced risk of colorectal cancer, according to a study in the December 14 issue of JAMA.
Dietary fiber has been hypothesized to reduce the risk of colorectal cancer, according to background information in the article. However, the results of numerous epidemiological studies have been inconsistent. Ecological correlation studies and many case-control studies have found an inverse ass
Illness takes a psychological toll on patient’s family
Parents of children with cancer commonly suffer symptoms of post-traumatic stress, both during treatment and years after their children survive the disease, say researchers at The Children’s Hospital of Philadelphia. The researchers recommend that hospital staff members routinely screen parents for such stress symptoms during a child’s treatment, and offer appropriate psychosocial treatments.
“We have found, time a
Laboratory studies show that cocaine causes changes in brain that increase vulnerability to environmental toxins in both adults and in offspring who were exposed to cocaine before birth, according to St. Jude
Adults who abuse cocaine might increase their risk of developing Parkinson’s disease (PD), and pregnant women who abuse cocaine could increase the risk of their children developing PD later in life, according to results of laboratory studies performed by investigator
A multi-institutional team, led by University of Chicago researchers, has taken a crucial step toward understanding and treating Rett syndrome (RS), a rare and often-misdiagnosed neurodevelopmental disorder that affects 1 in 10,000 children, mostly females.
In a study published in the Dec. 14, 2005, issue of the Journal of Neuroscience, the researchers describe in a mouse model for RS the source of erratic breathing, which has important implications for children with RS.
Doctors at the University of Virginia Health System have opened a new clinical trial to try and help people with emphysema breathe better. The study will test the safety and effectiveness of a bronchoscopic valve, an experimental device designed to channel air to healthier portions of the lung. The idea is to improve a patient’s physical functioning, tolerance for exercise and general quality of life.
The study device works by limiting airflow to a selected portion of the lun
A new case study by Mayo Clinic researchers provides preliminary evidence to suggest a component of green tea may lead to clinical improvement in patients with chronic lymphocytic leukemia (CLL). Findings are published online in Leukemia Research.
In the small case study, the researchers report on four patients who appeared to have an improvement in the clinical state of their disease after starting over-the-counter products containing epigallocatechin gallate (EGCG), an extra
’Essential’ system may be unnecessary in S. mutans
Leave it to the bacteria that cause tooth decay to be able to live without something all cells were thought to require.
Scientists have long believed a certain biochemical pathway involved in the folding and delivery of proteins to cell membranes is essential for survival. Now University of Florida researchers have discovered that Streptococcus mutans, the decay-causing organism that thrives in many a mouth, ca
Living organisms are dependent on being able to adjust the water content in their cells. This is achieved by regulating the flow of water through the cell membrane. Water is ‘turned on’ and ‘turned off’ by membrane proteins that function as water conduits and are called aquaporins. In the new issue of Nature, Professor Per Kjellbom and Associate Professor Urban Johanson, plant biochemists at Lund University, Sweden, describe how this takes place. The discovery is not only a breakthrough for pure
While botulinum toxin A, or BTXA, is widely known for its use in dermatology and aesthetic medicine, a review article in the Journal of Cosmetic Dermatology explores the drug’s other successful applications.
BTXA is popularly used to treat hyperhidrosis (excessive sweating) or to diminish wrinkles, but it is also a highly effective natural substance that normalizes muscle activity and can be used to reduce pain and itch.
Benefits of BTXA have been observed in treatment of hand
The first study of the effects of testosterone on mood, behavior and psychological health in men with mild Alzheimer disease finds significant improvements in quality of life, as assessed by caregivers.
Led by neuroscientists at the UCLA Alzheimer Disease Research Center and detailed in an early online release of the peer-reviewed journal Archives of Neurology, the double blind, placebo-controlled study used caregiver assessments to evaluate quality of life and used a battery o
Offering promise in the battle against cancer, the results from five studies highlighting new advances in the treatment of chronic myeloid leukemia (CML) – a slow-progressing, malignant bone marrow cancer – will be presented at the 47th Annual Meeting of the American Society of Hematology.
“The survival rate for leukemia has improved in the past two decades, thanks to new agents designed to treat patients,” said Brian J. Druker, M.D., Oregon Health and Science University, Port
