Yet another proven benefit of tight glucose control for those with type 1 diabetes

New study results confirm, for the first time, that intensive treatment of diabetic patients results in a significantly lower risk of heart disease. In fact, it can cut the risk of cardiovascular disease nearly in half.

Most common form of lung cancer may begin in a group of newly isolated lung stem cells

Working in a mouse model, the researchers isolated a novel type of lung cell that can divide into fresh copies of itself and into the two more specialized kinds of cells deep in the lung.

Specific genetic linkages to bipolar disorder

Despite an intensive effort, researchers have yet to identify the genes that cause bipolar disorder, yet the practical benefits of such a discovery could reap rich rewards for those suffering from the mental illness.

Researchers explore the genetic roots of congenital diaphragmatic hernias

To breathe normally, people need more than just healthy lungs. A diaphragm - the large muscle that creates a vacuum to draw air into their lungs - is also crucial.

Findings may help scientists improve the existing vaccine for yellow fever

In one of the first molecular studies of the human antibody response to yellow fever, Howard Hughes Medical Institute (HHMI) researchers and their colleagues have found the crucial bit of virus that people's immune systems need to spot and quash this often-fatal re-emerging disease.

New techniques use mitochondrial DNA as an early indicator for certain types of cancer

A pilot study at the National Institute of Standards and Technology (NIST), in support of the National Cancer Institute's Early Detection Research Network (EDRN), has validated the measurement accuracy of new techniques that use mitochondrial DNA as an early indicator for certain types of cancer.

Chronic insomnia medicines have not yet been rigorously evaluated for long-term use

Many of the medications widely used to manage chronic insomnia have not yet been rigorously evaluated for long-term use, according to an independent scientific panel convened this week by the National Institutes of Health.

Transplantation of spermatogonial stem cells isolated from leukemic mice restores fertility without inducing leukemia

While more than 70% of patients survive childhood leukemia, curative chemotherapy can often irreversibly impair the formation of spermatozoa, causing infertility in males.

High rates of herpes simplex virus 2 and syphilis among young drug users in Baltimore

The study found that women had significantly higher rates compared to their male counterparts, but did not find significant differences between injection drug users and non-injection drug users.

Claudin-1 regulates cellular transformation and metastatic behavior in colon cancer

Disruption of proteins expressed at the junctures between cells (known as tight junctions) is a hallmark of cancer cell invasion and spread (metastasis).

Fine tuning drug levels in neuroblastoma patients is effective

Monitoring and fine tuning the levels of the cancer drug topotecan in children with neuroblastoma holds promise for maximizing the drug's effectiveness while reducing its toxicity, according to investigators at St. Jude Children's Research Hospital.

MRI measurement of breast tumor volume predicts whether a patient's cancer will return

The study, performed at the University of California-San Francisco, of 58 breast cancer patients found that the best way to predict a patient's recurrence-free survival is to review the initial MR examination (before the patient has chemotherapy) and the final MR examination (after chemotherapy has been completed).

Inactive gene may explain higher incidence of prostate cancer in African-Americans compared to Caucasians

Among African-Americans with prostate cancer, a tumor-suppressing gene called GSTP1 is inactivated at a rate 3.5 times higher than among Caucasians, according to a study conducted at the San Francisco VA Medical Center (SFVAMC).

Scientists have tracked down the biological trigger that gives rise to Van Buchem disease

...a hereditary, disfiguring bone disorder that can cause blindness and deafness. The findings provide insight into long-range gene regulation and could lead to new treatments for osteoporosis and other crippling bone disorders.

Pandemics such as Ebola, SARS, and avian influenza demands a more holistic approach to disease control

The threat of potential pandemics such as Ebola, SARS, and avian influenza demands a more holistic approach to disease control, one that prevents diseases from crossing the divide between humans, their livestock, and wildlife, according to the Wildlife Conservation Society (WCS) in the most recent issue of the journal Foreign Affairs.
