A study published in the Jan. 1, 2004 issue of the American Journal of Psychiatry had a surprising start. As Michael Rohan, imaging physicist in McLean Hospital’s Brain Imaging Center,…
As readers of introductory psychology texts know, animals easily learn to fear a harmless stimulus, such as a tone, if that stimulus is paired with a painful one, such as…
More than 125,000 study participants who were free of diabetes, cancer, and cardiovascular disease at the start of a study were selected from the on-going Health Professionals Follow-up Study and…
Findings by a research team could eventually lead to the development of a protease inhibitor drug, which in combination with antibiotics could be used to treat anthrax cases later in…
The Centers for Disease Control and Prevention highly recommends the flu vaccine for certain high-risk groups including people with chronic illnesses, children between the ages of six and 23 months,…
Scientists injected laboratory-created sperm into eggs, and the resulting embryos grew to the point where they would normally be implanted into a womb. The experiment was done with mouse stem…
Combination drug therapy – also called highly active antiretroviral therapy (HAART) – made a huge difference in the treatment of HIV infection during the 1990s, changing HIV/AIDS into an illness…
Currently, nearly all the 30,000 cases of pancreatic cancer diagnosed annually are fatal within a matter of months because they are too advanced to remove surgically by the time they…
Research by scientists at Beth Israel Deaconess Medical Center (BIDMC) helps to explain the wide range of signs and symptoms associated with myotonic muscular dystrophy (MMD). The findings appeared in…
A study, led by McLean Hospital’s William Carlezon and Susan Andersen, found that adult rats given Ritalin as juveniles behaved differently than their placebo-treated counterparts in a host of tests…
For more than 30 years, it has been accepted in the medical community that women with arthritis are actually much less likely to experience accelerated bone loss. New findings, outlined…
A study of 35 obese people included three groups of volunteers; all were obese and had a body mass index above 30 kg/m2 and had insulin resistance. The first group…
SARS – severe acute respiratory syndrome – is a viral respiratory illness caused by coronavirus, a family of viruses also implicated in the common cold. SARS is a distinct form…
The effectiveness of antiretroviral therapy for HIV infection depends on how well patients adhere to complicated drug regimens. Researchers found that among patients with lower levels of adherence to their…
A research team at Brigham and Women’s Hospital (BWH) found that stroke risk for women increased proportionately with the number of cigarettes smoked each day. In contrast, women who stopped…
Type 1 diabetes develops when the body’s immune cells mistakenly attack the insulin-producing islet cells of the pancreas. As islet cells die, insulin production ceases, and blood sugar levels rise,…
A research team surveyed more than 2,000 physicians at U.S. academic health centers who had provided direct patient care during the preceding year. Among the questions asked were whether the…
As the American Psychiatric Association prepares for the Diagnostic and Statistical Manual of Mental Disorders’s fifth edition, there is debate over whether to eliminate milder forms of diseases to prevent…
Researchers found that adult rats exposed to a social stress during adolescence (ages approximating 13 to 15 years in humans) showed a significant decrease in a specific protein found in…
In a frog, the position of the heart is determined within the first hour in the womb, Harvard scientists have discovered. Researchers all over the world believe that frogs and…
While the research is a far cry from proving that humans sprang from clay, as some creation myths assert, it does provide a possible mechanism for explaining how life initially…
Normally, a protein regulates when and how body parts develop, but when mutated, it triggers a rare, often-lethal infant leukemia called mixed lineage leukemia. The newly identified protease enzyme, Taspase1,…
Working with colleagues at the University of Rochester School of Medicine, Harvard researchers found that giving mice a hormone known for building bones increased their production of blood stem cells.…
A study, published by Dana-Farber researchers in the September 2003 issue of the Journal of General Internal Medicine, suggests that increasing medical students’ opportunities to learn about end-of-life care will…
Matrix metalloproteinases (MMPs) and their regulators, the tissue inhibitors of metalloproteinases (TIMPs), form an intriguing partnership. MMPs work by breaking down the dense matrix surrounding cells, freeing them to wander…
“Scientists have wondered for a long time why madness and creativity seem linked, particularly in artists, musicians, and writers,” notes Shelley Carson, a Harvard psychologist. “Our research results indicate that…
Alzheimer’s disease is notoriously difficult to diagnose. Though sophisticated functional and cognitive tests can help, they often fail to distinguish between Alzheimer’s and other non-amyloid-based dementias, particularly frontotemporal dementia. The…
The results of three studies published together in the Aug. 31, 2003 online edition of Nature Immunology help explain the uncanny ability of T cells to home to problem areas…
“To initiate a memory is almost like creating a word processing file on a computer,” explains researcher Matthew Walker, instructor of psychiatry at Beth Israel Deaconess Medical Center and Harvard…
The prevalence of overweight and obese children has increased by 100 percent since the 1980s. Americans spend about $33 billion a year on weight loss products and services, however, only…
