New more-sensitive blood test catches recurring breast cancer a year earlier Posted: 28 Mar 2012 05:36 PM PDT A new blood test is twice as sensitive and can detect breast cancer recurrence a full year earlier than current blood tests, according to new research.

Standard test may miss food ingredients that cause milk allergy Posted: 28 Mar 2012 05:36 PM PDT The standard test used to detect milk-protein residues in processed foods may not work as well as previously believed in all applications, sometimes missing ingredients that can cause milk allergy, the most common childhood food allergy, which affects millions of children under age 3, a scientist has reported.

Key mechanism involved in Type 2 diabetes identified Posted: 28 Mar 2012 02:22 PM PDT Scientists have discovered a key protein that regulates insulin resistance -- the diminished ability of cells to respond to the action of insulin and which sets the stage for the development of the most common form of diabetes. This breakthrough points to a new way to potentially treat or forestall Type 2 diabetes, a rapidly growing global health problem.

Health impact, interplay of diet soft drinks and overall diet unravelled Posted: 28 Mar 2012 02:22 PM PDT Are diet sodas good or bad for you? The jury is still out, but a new study sheds light on the impact that zero-calorie beverages may have on health, especially in the context of a person's overall dietary habits.

With you in the room, bacteria counts spike -- by about 37 million bacteria per hour Posted: 28 Mar 2012 02:22 PM PDT A person's mere presence in a room can add 37 million bacteria to the air every hour -- material largely left behind by previous occupants and stirred up from the floor -- according to new research.

US cancer death rates continue to decline Posted: 28 Mar 2012 02:21 PM PDT A report from the nation's leading cancer organizations shows rates of death in the United States from all cancers for men and women continued to decline between 2004 and 2008.

Meditation improves emotional behaviors in teachers Posted: 28 Mar 2012 11:28 AM PDT Schoolteachers who underwent a short but intensive program of meditation were less depressed, anxious or stressed -- and more compassionate and aware of others' feelings. The novel project blended ancient meditation practices with the most current scientific methods for regulating emotions.

New layer of genetic information helps determine how fast proteins are produced Posted: 28 Mar 2012 11:28 AM PDT A hidden and never before recognized layer of information in the genetic code has been uncovered by a team of scientists, thanks to a new technique called ribosome profiling, which enables the measurement of gene activity inside living cells.

Danger of grill brushes identified Posted: 28 Mar 2012 11:28 AM PDT Physicians have identified a number of cases of accidental ingestion of wire grill brush bristles that required endoscopic or surgical removal.

Novel compound halts tumor spread, improves brain cancer treatment in animal studies Posted: 28 Mar 2012 11:27 AM PDT By stopping the spread of cancer cells into normal brain tissue in animal models, researchers have developed a new strategy for treating brain cancer that could improve clinical outcomes. The researchers treated animals possessing an invasive tumor with a novel molecule called imipramine blue, followed by conventional doxorubicin chemotherapy. The tumors ceased their invasion of healthy tissue and the animals survived longer than animals treated with chemotherapy alone.

Protein 'jailbreak' helps breast cancer cells live Posted: 28 Mar 2012 09:29 AM PDT Researchers have traced the molecular interactions that allow the protein survivin to escape the nucleus of a breast cancer cell and prolong the cell's life. The study may help in the development of better therapies and prognostics.

Stopping statin therapy increases risk of death for rheumatoid arthritis patients Posted: 28 Mar 2012 06:08 AM PDT Patients with rheumatoid arthritis (RA) who discontinue use of statin therapy are at increased risk of death from cardiovascular disease and other causes.

Epigenetic changes in blood samples may point to schizophrenia Posted: 27 Mar 2012 09:42 AM PDT Researchers have identified epigenetic changes – known as DNA methylation – in the blood of patients with schizophrenia. The researchers were also able to detect differences depending on how old the patients were when they developed the disease and whether they had been treated with various drugs. In the future this new knowledge may be used to develop a simple test to diagnose patients with schizophrenia.

Research gives hope to detecting cancer in early stages Posted: 27 Mar 2012 06:43 AM PDT Scientists have found a mechanism which causes normal cells to develop into cancer cells.
