New study shows erosive esophagitis healing linked to acid control

... These drugs reduce acid by blocking the action of tiny "pumps" within the acid-secreting cells of the stomach. Patients underwent an intraesophageal/intragastric 24-hour pH study on day five. When assessing acid control, clinicians measure pH on a 14-point scale, with 7 being neutral and lower numbers b...

Marijuana-derived drug suppresses bladder pain in animal models

... IP 751 by introducing the drug into a liposome, a tiny sac surrounded by fatty acids, allowing for the drug to be introduced directly into the bladders of rat models of varying degrees of bladder inflammation. IP 751 significantly suppressed bladder overactivity in both animal models. Bladder overactivit...

Damage from oxygen may be one cause of Parkinson's disease

...adicals are damaging proteins in mitochondria, the tiny cellular 'batteries' of brain cells. This damage may be one main cause of Parkinson's Disease (PD), the chronic movement disorder that affects at least one million Americans. UVa scientists believe the damage is taking place in a large protein struc...

Image-guided biopsy can help patients avoid unnecessary kidney removal

...procedure is performed through the skin, through a tiny incision (only 3-4 mm). Imaging guidance (either ultrasound or CT) allows us to watch our needle as it enters the mass, decreasing the risk of damage to adjacent structures and ensuring that we are sampling the correct tissue," said Katherine Mature...

Combined contrast enhanced MRI shows promise

...ver are not evenly distributed throughout, so that tiny changes in needle placement will result in potentially large changes in biopsy interpretation. Because of these limitations, alternative methods such as CCE MR need to be developed," said Claude Sirlin, MD, lead author of the study. "Except for CCE ...

Rapid lung function decline raises risk of death and hospitalization

...emphysema or chronic bronchitis. In emphysema, the tiny air sacs of the lung (alveoli) become enlarged and their walls are destroyed. In chronic bronchitis, the bronchial glands enlarge, causing chronic cough and excess mucus. Ten to 15 percent of all smokers develop COPD as a result of irritants in tobac...

Gold beads show previously unseen parts of the eye

...earch Institute in San Francisco, Calif., injected tiny gold beads into various areas in the eye which are usually difficult to visualize. The implanted beads were then imaged using a digital dental-type X-ray system and 3-dimensional reconstruction techniques. The study showed that three-quarters of th...

The alveola tiny air sacs in the lung where exchanges of gases between the respiratory and circulatory systems takes place are protected from invading microbes by the alveolar macrophage. Macrophages are white blood cells involved in the inflammatory response throu...

Chemical guidance of T cells leads to immunologic memory and long-term immunity

...s hundreds of millions of CD8+ T cells, but only a tiny fraction of them become activated during an infection. These are selected because each CD8+ T cell carries a unique surface protein called a T-cell receptor, which recognizes only specific antigens (pieces of virus or bacteria that trigger the immune...

Oops! Researchers publish new findings on the brain's response to costly mistakes

... create images based on blood flow, and can detect tiny changes in the rate of blood flow in and out of various areas of the brain. The more blood flowing to a specific area, the more active the cells in that area are and therefore, the more processing that is going on in those brain cells. "We hypothes...

Sustained blood pressure treatment lowers dementia risk in elderly

... and the brains of Alzheimer's patients often have tiny blood clots and small infarcts, she said. While only 7.8 percent of the 848 men were diagnosed with dementia, even those who did not have dementia showed cognitive declines. But men who had untreated hypertension had significantly more cognitive de...
