Dioxins in food chain linked to breastfeeding problems

Exposure to dioxins during pregnancy harms the cells in rapidly-changing breast tissue, which may explain why some women have trouble breastfeeding or don’t produce enough milk, according to a University of Rochester Medical Center study.

Discovery of novel mechanism controlling tumor growth in the brain

As survival rates among some patients with cancer continue to rise, so does the spread of these cancers to the brain - as much as 40 percent of all diagnosed brain cancers are considered metastatic, having spread from a primary cancer elsewhere in the body.

Do omega-3 fatty acids prevent depression in coronary heart disease?

Depression is an established risk factor for the development of coronary heart disease (CHD) in healthy patients and for adverse cardiovascular outcomes in patients with existing CHD. Dietary factors resulting in lower levels of omega-3 fatty acids not only increase CHD risk, but may also be involved in the pathophysiology of depression.

Doctors and hospitals look for ways to cut costs, improve quality

The "patient-centered" practices movement is growing in popularity, the New York Times reports. Primary care physicians in the practices "spend more time with patients, emphasize prevention and education" to keep patients healthy and "can handle many medical problems without referrals to specialists." Often, "this kind of care can reduce a patient's medical bills."

Researchers discover why Lou Gehrig's disease speeds along more rapidly in some patients than others

University of Florida scientists have discovered why a paralyzing brain disorder speeds along more rapidly in some patients than others - a finding that may finally give researchers an entry point toward an effective treatment for amyotrophic lateral sclerosis, often referred to as ALS or Lou Gehrig's disease.

New lung cancer therapy with vaporized viral vector shows promise

A new lung cancer therapy employing a vaporized viral vector to deliver a cancer-inhibiting molecule directly to lung tissue shows early promise in mouse trials, according to researchers at the Ministry of Education, Science and Technology in Korea.

Prevalence and predictors of antioxidant supplement use during breast cancer treatment

A new study finds that many women with breast cancer take antioxidant supplements while undergoing cancer treatment, even though the consequences of doing so are unknown.

Cisplatin doubles lung cancer survival time in mice

A lung cancer treatment that inhibits nicotine receptors was shown to double survival time in mice, according to Italian researchers.

Gene activity reveals dynamic stroma microenvironment in prostate cancer

As stroma - the supportive framework of the prostate gland - react to prostate cancer, changes in the expression of genes occur that induce the formation of new structures such as blood vessels, nerves and parts of nerves, said researchers at Baylor College of Medicine in a report that appears in the current issue of the journal Clinical Cancer Research.

Research identifies 3D structure of key nuclear pore building block

The genome of complex organisms is stashed away inside each cell's nucleus, a little like a sovereign shielded from the threatening world outside.

Research shows how cells tell time

In a new study appearing online this week in the Proceedings of the National Academy of Sciences, Dr. Liu and his co-workers have found that this mold, which uses a protein called FRQ as the main gear of its clock, marks time by a sequence of changes in the protein's chemical structure.

New antibiotics could come from a DNA binding compound that kills bacteria in 2 minutes

A synthetic DNA binding compound has proved surprisingly effective at binding to the DNA of bacteria and killing all the bacteria it touched within two minutes.

New imaging technique: toward spinal cord regeneration?

The axon is a part of the neuron through which nerve impulses are transmitted, and at the end of which is located the synapse, which connects it to another neuron. In the event of a lesion, the axon is the component which must be regenerated in order to restore the connections between the different neurons and re-form the nerve.

Rhes protein responsible for brain cell damage in Huntington disease

Johns Hopkins brain scientists have figured out why a faulty protein accumulates in cells everywhere in the bodies of people with Huntington's disease (HD), but only kills cells in the part of the brain that controls movement, causing negligible damage to tissues elsewhere.

Drug derived from the hydrangea root shows promise for autoimmune disorders

A drug derived from the hydrangea root, used for centuries in traditional Chinese medicine, shows promise in treating autoimmune disorders, report researchers from the Program in Cellular and Molecular Medicine and the Immune Disease Institute at Children's Hospital Boston (PCMM/IDI), along with the Harvard School of Dental Medicine.

Cancer vaccine efficacy enhanced using anti-diabetic drug Metformin

After a vaccination or an infection, the human immune system remembers to keep protecting against invaders it has already encountered, with the aid of specialized B-cells and T-cells. Immunological memory has long been the subject of intense study, but the underlying cellular mechanisms regulating the generation and persistence of long-lived memory T cells remain largely undefined. Now, University of Pennsylvania School of Medicine researchers have found that a common anti-diabetic drug might enhance the effectiveness of vaccines. The findings are described this week in an advanced online publication of Nature.

Study gives clues to how ultra-rare adrenocortical cancer forms

At the ends of chromosome are special pieces of DNA called telomeres. Think of it as the little tip that caps off a shoelace. The telomeres send signals to the cells to let them know it's the end point, not a break that should be repaired.

Discovery of critical marker of response to gemcitabine in pancreatic cancer

A protein related to aggressive cancers can actually improve the efficacy of gemcitabine at treating pancreatic cancer, according to a Priority Report in Cancer Research, published by researchers at Thomas Jefferson University.

Discovery of two proteins may lead to more effective treatment of endocarditis and infections associated with implants

A research team at the Faculty of Odontology at Malmö University in Sweden has discovered two new proteins that are of importance to the survival of bacteria and their colonization of the human body. Besides enhancing our knowledge of the ability of bacteria to spread, the findings may also lead to more effective treatment of endocarditis and infections associated with implants.

Discovery of new genetic immune disorder in children

Your immune system plays an important function in your health - it protects you against viruses, bacteria, and other toxins that can cause disease. In autoinflammatory diseases, however, the immune system goes awry, causing unprovoked and dangerous inflammation.
