Diet found especially beneficial for female offspring
It has been estimated that up to 32 million Americans have adopted the low-carb style of eating, in part because of its quick and dramatic results. Converts often maintain components of low-carb eating long after they’ve officially finished dieting.
Not surprisingly, a growing number of pregnant women now explore ways to continue low-carb routines through gestation, in fact there are several chat rooms devoted
Mount Sinai researchers identify a new mechanism that contributes to the development of some breast and ovarian cancers
Researchers at Mount Sinai School of Medicine have discovered a new mechanism of activation of a pathway known to be implicated in many cancers. Additionally, the researchers found that when this mechanism is blocked cells may become more sensitive to radiation and chemotherapeutic agents, thus making them easier to destroy. The research was published in the Novem
A promising experimental compound prevents cholesterol gallstone disease in mice by stimulating the biochemical pathway that controls bile acid secretion by the liver, according to new studies by Howard Hughes Medical Institute researchers.
The findings suggest new approaches to developing drugs to prevent the disease, which afflicts some 20 million people a year. The studies also propose novel strategies for developing diagnostic tests to identify people with a genetically in
Experts are recommending that adolescents and some adults be vaccinated against whooping cough to help prevent infection and potential transmission to infants, according to the December 15 issue of Clinical Infectious Diseases, now available online.
Worldwide, about 300,000 people–mostly infants–die each year from whooping cough, known scientifically as pertussis. The disease is caused by Bordetella pertussis, a type of bacterium that infects the human respiratory tract. Vacc
National Security Advisor Condoleezza Rice today underwent embolization—a non-surgical treatment to kill uterine fibroid tumors. While embolization is a good option for some patients, a less invasive option is on the horizon, as outlined this week in the American Journal of Obstetrics and Gynecology.
The new procedure could someday replace both embolization and the even more invasive hysterectomy, especially for patients who would still like to have children after treatment, acco
Research that could lead to a breakthrough in the treatment of HIV has scooped a University of Manchester scientist a prestigious industry award.
Dr Curtis Dobson’s work was voted Project of the Year at the annual Northwest Biotechnology Awards ceremony hosted by the Northwest Development Agency programme, Bionow. His research concerns the interaction between human proteins and viruses and the development of novel anti-infective compounds that could become the next generation of HI
Waterloo’s battlefield is reigniting the debate about whether modern medicine is always good for you, according to University College London (UCL) scientists who are launching a study of why some critically ill patients recover and others die from multiple organ failure – the number one killer of patients in intensive care.
Speaking today at a public lecture held in London, Professor Mervyn Singer from UCL’s Institute of Intensive Care Medicine said the impressive survival stati
Each year tuberculosis kills about three million people in the world. In particular it is responsible for the death of more than one-third of HIV- infected people, who prove particularly susceptible owing to a decline in immune defences. The agent responsible is a bacterium of the species Mycobacterium tuberculosis, also termed Koch’s bacillus, after the scientist who discovered it in 1882.
Molecular epidemiology has proved valuable for understanding the transmission and control
Study of development of cancer in seven Swedish counties establishes connection
A statistically determined correlation between radioactive fallout from the Chernobyl accident and an increase in the number of cases of cancer in the exposed areas in Sweden is reported in a study by scientists at Linköping University, Örebro University, and the County Council of Västernorrland County. It is the first study demonstrating such a correlation. It is being published in the scientific jour
Using brain imaging, researchers at Columbia University Medical Center (CUMC) have found clear differences in brain function between healthy people who carry a genetic risk factor for Alzheimer’s disease and those who lack the factor.
Because researchers believe that Alzheimer’s disease starts changing the brain years before any symptoms appear, the disease may be most amenable to treatment in these pre-clinical stages. If so, detecting the early changes will be crucial
Psychiatrists at Rush University Medical Center are testing a noninvasive technique that uses repeated short bursts of magnetic energy to stimulate nerve cells in the brain to treat major depression. The therapy is called Transcranial Magnetic Stimulation (TMS), and Rush is enrolling patients in a clinical trial to determine if TMS is safe and effective.
“We think that this is landmark research for a new antidepressant treatment,” said Dr. Philip Janicak, Rush psychiatrist a
Anyone who has ever had a urinary tract infection knows that they can be difficult to fight.
The bacterium E. coli is responsible for about 80 percent of human urinary tract infections. Scientists at the University of California, Santa Barbara have made important strides in understanding E. coli at the molecular level in an effort to discover the mechanisms by which E. coli cause urinary tract infections. The findings, the result of two years of study, are published in the Novemb
Ion channels made light sensitive, allowing remote control of firing
Scientists at the University of California, Berkeley, have given “blind” nerve cells the ability to detect light, paving the way for an innovative therapy that could restore sight to those who have lost it through disease.
A team lead by neurobiologist Richard H. Kramer, UC Berkeley professor of molecular and cell biology, and Dirk Trauner, assistant professor of chemistry, inserted a light-activated
It depends on what we’re thinking about!
Researchers are using functional magnetic resonance imaging (fMRI) to probe brain activity in search of the answer. According to a new fMRI study using a “diary” method to collect memories, it all depends on what we’re thinking about!
Researchers have known for decades that thinking about autobiographical facts is different from thinking about autobiographical episodes that happened only once. Since both kinds of thoughts
One in three smokers or former smokers screened for lung cancer at a baseline and one year follow-up visit using a recent advance in computed tomography tested positive according to a new study. Of those, 12 percent had lung biopsies, and 7 percent were diagnosed with lung cancer. The findings, along with detailed characterizations of practiced follow-up patterns, appear in the January 1, 2005 issue of CANCER, a peer-reviewed journal of the American Cancer Society.
Low dose spiral
Educating children in primary school and adults at the beach about the benefits of wearing sun-protective hats and clothing can effectively motivate them to cover up and reduce their exposure to cancer-causing ultraviolet radiation, according to a systematic review of evidence. The review appears in the American Journal of Preventive Medicine.
Skin cancer is the most common type of cancer in the United States. The incidence of one type — melanoma — is rising, due in part to inc
