Researchers unveil new and improved lung cancer staging system

For the first time in more than 10 years, the universally accepted lung cancer staging system has been revised to more accurately reflect the prognosis for patients with non-small cell lung cancer (NSCLC).

Privacy still spurs controversy in electronic medical sharing debate

States that have passed privacy laws restricting the ability of hospitals to disclose patient information have seen the sharing of electronic medical records suffer by more than 24%, according to the Management Insights feature in the current issue of Management Science, the flagship journal of the Institute for Operations Research and the Management Sciences (INFORMS®).

Bacteria in yougurt may help gastric-bypass patients lose more weight

New research from the Stanford University School of Medicine and Stanford Hospital & Clinics suggests that the use of a dietary supplement after Roux-en-Y gastric bypass surgery can help obese patients to more quickly lose weight and to avoid deficiency of a critical B vitamin.

Naringenin eliminates excess fat, prevents obesity

A flavonoid derived from citrus fruit has shown tremendous promise for preventing weight gain and other signs of metabolic syndrome which can lead to Type 2 Diabetes and increased risk of cardiovascular disease. The study, led by Murray Huff of the Robarts Research Institute at The University of Western Ontario looked at a flavonoid (plant-based bioactive molecule) called naringenin. The findings are published online in the journal Diabetes.

Actin reorganization elucidates cause of memory loss

Memories aren't made of actin filaments. But their assembly is crucial for long-term potentiation (LTP), an increase in synapse sensitivity that researchers think helps to lay down memories. In the July 13, 2009 issue of the Journal of Cell Biology , Rex et al. reveal that LTP's actin reorganization occurs in two stages that are controlled by different pathways, a discovery that helps explain why it is easy to encode new memories but hard to hold onto them.

'Molecular mimicry' explains immune system failure in newborns

Group B Streptococcus (GBS), a bacterial pathogen that causes sepsis and meningitis in newborn infants, is able to shut down immune cell function in order to promote its own survival, according to researchers at the University of California, San Diego School of Medicine and the Skaggs School of Pharmacy and Pharmaceutical Sciences.

Dynamic molecular mechanism keeps brain activity stable

In the brain, many types of synaptic proteins are spatio-temporally regulated to maintain synaptic activity at a constant level. Here, the Japanese research group led by Professor Masaki Fukata, Drs. Yuko Fukata and Jun Noritake in National Institute for Physiological Sciences, Japan, found that two types of palmitoylating enzymes finely-tune the location and function of a major synaptic protein, PSD-95, in different ways. They also found that this mechanism contributes to keeping synaptic activity stable when synaptic activity dynamically changes.

Childhood obesity linked to parental influence, scientists say

The relationships between children and their parent of the same gender in the earliest years of life could be the key to understanding why some young people become obese and others do not, new research conducted by the EarlyBird Diabetes Study has shown.

A study published today in the International Journal of Obesity indicates that girls whose mothers are classified as clinically obese are significantly more likely to struggle with weight problems in childhood, with a similar relationship existing between obese fathers and their sons.

Mystery E. coli genes essential for survival of many species

Scientists have shown that E. coli – one of the best known and extensively studied organisms in the world – remains an enigma that may hold the key to human diseases, such as cancer.

Scientists identify enzyme important in aging

PITTSBURGH, July 10 – The secret to longevity may lie in an enzyme with the ability to promote a robust immune system into old age by maintaining the function of the thymus throughout life, according to researchers studying an "anti-aging" mouse model that lives longer than a typical mouse.

Environmental manganese good in trace amounts but can correlate to cancer rates

WINSTON-SALEM, N.C. – In the first ecological study of its kind in the world, a Wake Forest University Baptist Medical Center researcher has uncovered the unique finding that groundwater and airborne manganese in North Carolina correlates with cancer mortality at the county level.

PTs say proper fit and use of walking aids can prevent fall-related injuries in elderly

ALEXANDRIA, VA— The American Physical Therapy Association (APTA) is urging elderly adults who use canes and walkers as walking aids to be properly assessed and fitted by a physical therapist to avoid fall-related injuries. This advice comes in response to a study published in the Journal of the American Geriatrics Society (June 2009), which found that 47,000 senior citizens end up in emergency rooms each year due to falls from improper use and fit of walkers and canes.

Researchers consider herd movements to help eradicate bovine TB

In 2008, the U.S. Department of Agriculture spent $31 million to depopulate herds of cattle affected by bovine tuberculosis (TB), even though the risk of the disease has been significantly reduced in the U.S. over the past several decades. Worldwide, especially in developing countries, the disease persists, which could threaten the U.S. cattle industry in terms of international trade.

Pdx1 molecule discovery a step toward reactivated insulin-producing beta cells

PHILADELPHIA – For years researchers have been searching for a way to treat diabetics by reactivating their insulin-producing beta cells, to no avail. Now, they may be one step closer. A protein, whose role in pancreatic development has long been recognized, has been discovered to play an additional and previously unknown regulatory role in the development of cells in the immature endocrine system. These cells ultimately give rise to pancreatic islet cells, which include beta cells.

Between the devil and the deep blue sea

Expansion of coastal cities is accompanied by a decline in the quality of life of the people, which was the reason they moved to the coastal zone instead of bringing growing welfare to the inhabitants. Many Megacities such as Tokyo (pop. 36.000.000), New York (22.000.000) and London (12.000.000) are found in the coastal zone. Coastal protection measures give a sense of false security and require increasingly expensive infrastructure.
