Gender linked to skin cancer

Gender linked to skin cancer
Inherent gender differences instead of more sun exposure may be one reason why men are three times more likely than women to develop certain kinds of skin cancer, say scientists at Ohio State University Medical Center. Squamous cell carcinoma is the second most common form of skin cancer, accounting for nearly 200,000 new cases in the United States each year. While occurring more often than melanoma, squamous cell carcinoma is not nearly........Go to the Skin news blog (Added on 4/1/2007 9:10:23 PM)

Should single parents stay that way?

Should single parents stay that way?
In an age when cohabitation and divorce are common, single parents concerned about the developmental health of their children may want to choose new partners slowly and deliberately, new research from The Johns Hopkins University suggests. The reason for taking your time? The more transitions children go through in their living situation, the more likely they are to act out, Johns Hopkins sociologists Paula Fomby and Andrew Cherlin report.........Go to the Society medical news blog (Added on 3/29/2007 10:35:37 PM)

Omega-3 Fatty Acid And Alzheimer's Disease?

Omega-3 Fatty Acid And Alzheimer's Disease?
Nutritionists have long endorsed fish as part of a heart-healthy diet, and now some studies suggest that omega-3 fatty acids found in the oil of certain fish may also benefit the brain by lowering the risk of Alzheimer's disease. In order to test whether docosahexaenoic acid (DHA), an omega-3 fatty acid, can impact the progression of Alzheimer's disease, scientists at Washington University School of Medicine and Saint Louis University School of........Go to the Neurology news blog (Added on 3/29/2007 10:03:31 PM)

Breast Cancer Patients For Reconstruction

Breast Cancer Patients For Reconstruction
Forty-four percent of surgeons do not refer the majority of their patients with breast cancer to a plastic surgeon previous to the initial surgery when the woman is choosing her therapy course, as per a new study by scientists at the University of Michigan Comprehensive Cancer Center. The finding may help explain the consistently low number of women who pursue breast reconstruction after mastectomy. The scientists surveyed 365 surgeons,........Go to the Breast-cancer-blog (Added on 3/29/2007 4:58:52 AM)

RF ablation effective for inoperable lung cancer

RF ablation effective for inoperable lung cancer
A minimally invasive procedure known as radiofrequency (RF) ablation is effective for treating lung cancer in patients who are not candidates for surgery, as per a Rhode Island Hospital study reported in the recent issue of the journal Radiology. Damian Dupuy, MD, director of ablation at Rhode Island Hospital and professor of diagnostic imaging at The Warren Alpert Medical School of Brown University, conducted a study of 153 patients who........Go to the Lung-cancer-blog (Added on 3/29/2007 4:41:30 AM)

MRI Detects Most Missed Opposite Breast Cancers

MRI Detects Most Missed Opposite Breast Cancers
Up to 10 percent of women newly diagnosed with cancer in one breast develop cancer in the opposite breast. Results of a major clinical trial show that magnetic resonance imaging (MRI) scans are highly effective tools for quickly identifying these opposite breast cancers, detecting diseased tissue that other screening methods missed. In the new trial, conducted by the American College of Radiology Imaging Network (ACRIN) and funded by the........Go to the Breast-cancer-blog (Added on 3/28/2007 10:21:38 PM)

Child's play is serious study of cause and effect

Child's play is serious study of cause and effect
It's not child's play to Laura E. Schulz, assistant professor of brain and cognitive sciences at MIT, to figure out what child's play is all about. Schulz spoke March 21 at an MIT Museum Soap Box event, "Twisting the Lion's Tail: Exploratory Play and Children's Causal Learning".

A Remedy For What Ails Medicine

A Remedy For What Ails Medicine
Today men and women attend medical school in equal numbers. But for most women who go on to academic medicine, that's also where the numbers stop adding up. Just twelve percent of women faculty members are promoted to full professor, compared with one-third of male faculty. Furthermore, in the nation's 125 medical schools, on average there are only thirty-five women full professors compared with 188 male full professors per school.

Gene Test After Heart Transplant

Gene Test After Heart Transplant
New research suggests a genomic test may provide detailed information on how well a transplanted heart is performing. The gene expression profiling (GEP) test, known as the Allomap® test, is currently used to detect the absence of heart transplant rejection instead of routine invasive heart muscle biopsies, but has now been shown to correlate with oxygen saturation levels, the pressure in the heart before pumping, and the electrical........Go to the Heart news blog (Added on 3/27/2007 9:51:17 PM)

Ring-around-the-cell

Ring-around-the-cell
Breaking down bone is a tough job. Yet, our bones undergo remodeling every day of our lives, as old material is cleared away so that new bone can form. In diseases such as osteoporosis, an imbalance in this process is responsible for the characteristic bone loss. New research at the Weizmann Institute of Science, which recently appeared in the online journal PLoS ONE, has revealed in unprecedented detail how the roving cells whose job is to........Go to the Research news blog (Added on 3/27/2007 9:42:41 PM)

Pulsing Light Silences Overactive Neurons

Pulsing Light Silences Overactive Neurons
Researchers at the MIT Media Lab have invented a way to reversibly silence brain cells using pulses of yellow light, offering the prospect of controlling the haywire neuron activity that occurs in diseases such as epilepsy and Parkinson's disease. Such diseases often must be treated by removing neurons that fire incorrectly. The new MIT research could lead to the development of optical brain prosthetics to control neurons, eliminating the........Go to the Neurology news blog (Added on 3/27/2007 8:56:59 PM)

Estrogen and Bone Protection

Estrogen and Bone Protection
Scientists at the University at Buffalo have described a novel pathway by which estradiol, the primary estrogen in humans, aids in maintaining bone density, a function critical to avoiding osteoporosis. It is well known that estrogen is essential for healthy bone, and that when the production of estrogen is reduced, as occurs normally in postmenopausal women and pathogenically after exposure to radiation or chemotherapeutic drugs, bones........Go to the OBGYN news blog (Added on 3/25/2007 9:16:29 PM)

Low-dose aspirin beats high-dose
The use of medicines to fight cardiovascular disease has been a primary focus of research in this area for the past several decades, as combinations of interventions and medicinal treatment have gradually begun to increase long-term survival rates. Two studies presented today at the American College of Cardiology's 56th Annual Scientific Session look at the measurable impact of the use of aspirin and other maintenance therapies, and one........Go to the Heart-watch-blog (Added on 3/25/2007 9:05:12 PM)

New Superbug Weapon

New Superbug Weapon
Imagine the desperation of trying to fight lethal infections when antibiotics fail to work. That scenario usually found with "hospital superbugs" may well improve thanks to a discovery by a research team at the University of British Columbia, in collaboration with UBC spin-off company Inimex Pharmaceuticals, that has identified a peptide that can fight infection by boosting the body's own immune system.

Fats in our stomach may reduce the protective effects of antioxidants such as vitamin C. Researchers at the University of Glasgow observed that in the presence of lipid the ability of antioxidants, such as ascorbic acid (the active component of vitamin C), to protect against the generation of potential cancer-forming compounds in the stomach is less than when no lipids are present.
