Stem Cell Marker Identified in Head and Neck Cancer

...e current finding in head and neck tumors does not pinpoint the exact stem cells, the researchers believe, but rather narrows down the field. The percent of cells within a tumor expressing CD44 varied from one sample to the next, with one sample composed of as high as 40 percent of these cells. Studies in oth...

Role of Appetite Hormone MCH in Insulin Production Revealed

...rni. The next step in the research process is to pinpoint exactly how MCH is regulating the growth of beta cells and identify which proteins are involved in this growth process. “We know MCH is having an effect on both growth and function likely by recruiting different proteins. It will be worth exploring w...

NIMH Studies Woman’s Hormonal Cycl

...cuit activity in humans has remained unclear. To pinpoint hormone effects on the reward circuit, Berman and colleagues scanned the brain activity of 13 women and 13 men while they performed a task involving simulated slot machines. The women were scanned before and after ovulation. The fMRI pictures showe...

Earlier this week, media had also reported two persons succumbing to suspected viral encephalitis (brain inflammation) or meningitis, hours after they reached local nursing home with fever and progressive paralysis. Later, two more f...

African-American Mothers More Likely to Deliver Prematurely

...sponse to infection, but they are still working to pinpoint causes of preterm birth. 'By understanding specifically what results in this health disparity in African-American women, we can gain a tremendous amount of insight into a normal birth process in respect to preterm birth,' said Muglia. 'If we can wo...

Computer Tool Helps Pinpoint Risky Gene Mutations

...harmful or benign. Our computational test may help pinpoint which one it is. We hope the system will eventually give counselors and doctors an important new tool to help them advise patients about whether they need to take preventive steps to keep cancer from developing.” Karchin, who earned a doctorate in ...

Study Links Attempted Suicide With Genetic Evidence

... says that although the Hopkins-led study does not pinpoint a specific gene responsible for attempted suicide, it does suggest a “neighborhood” in which the gene might be found. She adds that the next step is to further narrow the search and find the “address.” “Once we have located the specific gene,” she sa...

Abnormalities in Eye Movements and Attention can Predict Schizophrenia

...l one can pay attention to a task together help to pinpoint risk factors related to schizophrenia. “I was ab...c study. That sort of research may help scientists pinpoint the gene or genes that cause schizophrenia. “The study of schizotypic individuals offers a unique ...

A Combination of Botox and Surgery Cures Migraines

...S. – includes using the anti-wrinkle drug Botox to pinpoint which of several specific muscles in the forehead, back of the head or temple areas may be serving as "trigger points" to compress, irritate or entrap nerves that could be causing the migraine. Because Botox temporarily paralyzes muscles, usually ...

Freezing Kidney Tumors Effective and Less Expensive Than Laparoscopy

... those studied. The radiologist uses imaging to pinpoint the tumor, and then inserts the cryoprobe through the skin, similar to the way a biopsy is performed. This can be performed under general anesthesia, but is often possible with only local anesthesia and conscious sedation. By using imaging the radiol...

Outpatient Treatment Kills Benign Bone Tumors Nonsurgically With Heat

...using CT imaging an interventional radiologist can pinpoint the precise location of the lesion and deliver a targeted treatment directly to the site, destroying the tumor inside the bone while leaving the remaining healthy bone intact. Radiofrequency ablation, performed by interventional radiologists on an ou...

Study Links Tooth Decay and Gum Infections to Ethnicity and Country of Origin

...es can be developed, such as diagnostic tests that pinpoint the presence of harmful oral bacteria that may be more common in certain ethnic groups." Source-Eurekalert SM...

Tumors Targeted Naturally

... do normal cells, a fact that allows scientists to pinpoint tumor cells lurking among the body's scores of cell types. A popular approach employs a cell-binding agent, such as a monoclonal antibody, that is powerfully attracted to the target receptor and holds fast to any cell displaying it. Although this s...

Detection of Malignant Breast Tumors Made Simpler and More Effective

...r. The agent also may be used during surgery to pinpoint the location of hydroxyapatite, and therefore the breast cancer cells themselves, Frangioni notes. His group began working to develop agents to target hydroxyapatite six years ago, but efforts were stalled by the inability to manufacture large qua...

A Sweet Step Toward New Cancer Therapies

... be used to identify sulfate-laden proteins and to pinpoint the location of the sulfate groups on them. In the latest research, they extended the technique to sugars, an even more challenging task. "Sugars are not like other biomolecules," Hakansson said. "They're linked rings with lots of branches, like ...

Obesity can Cause Asthma too

...meone with normal weight. Researchers could not pinpoint what caused the increased risk of asthma, though. Obesity causes impairments in lung function, such as a reduction in lung volume and an increase in the amount of oxygen used during breathing, but these on its own would not be enough to induce the co...

Intensive Psychotherapy Effective in Treating Bipolar Disorder

... out to compare several types of psychotherapy and pinpoint the most effective treatments and treatment combinations. With 293 participants, David Miklowitz, Ph.D., of the University of Colorado and colleagues set out to test the effectiveness of three types of standardized, intensive, nine-month-long psych...

More Mutations Of Gene That Cause Skin Disorders And Asthma Discovered

...eatment more specific for ethnic groups as well as pinpoint various forms of the gene’s effects by genetic tests. Says Irwin McLean at the College of Medicine, Dentistry and Nursing at the University of Dundee, who led the study:” Once we cracked this exceptionally difficult gene, we were surprised to lea...

Study Finds Dietary Fat Interacts With Genes

...t we study nutrigenomics with the idea that we can pinpoint people who may be at higher risk for certain conditions like cardiovascular disease, allowing these individuals to proactively alter the way nutrition affects their genes,” says Ordovas. “Once we are able to do this, we may develop several sets of gu...

CT Imaging With Novel Contrast Agent May Predict Heart Attack in Waiting
