Adults can be retrained to learn second languages more easily, says UCL scientist

Our ability to hear and understand a second language becomes more and more difficult with age, but the adult brain can be retrained to pick up foreign sounds more easily again. This finding, reported by Dr Paul Iverson of the UCL Centre for Human Communication, at the "Plasticity in Speech Perception 2005" workshop - builds on an important new theory that the difficulties we have with learning languages in later life are not biological and that, given the right stimulus, the brain can be retrained. more  

Study explains why up to eight percent of cancers go undetected

A few years ago, Medhat Osman, M.D., Ph.D., had a patient who was scanned due to a suspicion of lung cancer using positron emission tomography (PET) and computer tomography (CT) technology. The scan came back negative, but the patient then complained of a problem with his leg. more

Fish oil does not lower risk of heart problems for patients with implantable defibrillators

Even though previous research has shown that fatty acids from fish oil reduce the risk of sudden cardiac death, patients with implantable defibrillators who took fish oil supplements did not see a reduction in serious heart rhythm abnormalities, according to a study in the June 15 issue of JAMA. more  

Phase I study examines biomarkers for response to erlotinib in glioma

Researchers have found two biomarkers that, in patients with a malignant type of brain tumor called glioblastoma multiforme, were associated with response to the cancer drug erlotinib (Tarceva). Patients with tumors that expressed high levels of epidermal growth factor receptor (EGFR) and low levels of phosphorylated PKB/Akt, an enzyme, responded better to erlotinib than patients with low levels of EGFR expression and high levels of phosphorylated PKB/Akt. The study findings appear in the June 15 issue of the Journal of the National Cancer Institute. more

New blood test may detect risk of rare complication from anesthesia 

A rare but potentially life-threatening inherited condition called malignant hyperthermia (MH) may strike surgical patients who receive common drugs for general anesthesia. Usually there is no outward sign of a problem before the drugs are given, but the drugs may trigger abnormal metabolic responses, such as a rapid rise in body temperature, muscle rigidity and other complications that may constitute a medical emergency. more

Orlistat and weight-loss techniques helpful in improving weight management 

When combined with diet, exercise and behavioral therapy, orlistat, a drug that decreases fat absorption, appears helpful for improving weight management in obese adolescents, compared with placebo, according to an article in the June 15 issue of JAMA. more

Tight glucose control lowers cvd by about 50 percent in diabetes

A significantly lower risk of heart disease can now be added to the list of proven long-term benefits of tight glucose control in people with type 1 diabetes. Researchers announced this finding today at the annual scientific meeting of the American Diabetes Association after analyzing cardiovascular (CVD) events such as heart attack, stroke, and angina in patients who took part in the Diabetes Control and Complications Trial (DCCT) years ago. more
