Nanotechnology's miniature answers to developing world's biggest problems

...diation: including nanotech-based innovations that destroy air pollutants with light; make catalytic converters more efficient, cheaper and better controlled; detect toxic materials and leaks; reduce fossil fuel emissions; and separate gases. 8. Construction: including nano-molecular structures to make aspha...

'Nanoshells' simultaneously detect and destroy cancerous cells

...ed on nanoscale particles that can both detect and destroy cancerous cells. The report appears in the April 13 issue of the American Chemical Society's journal Nano Letters . ACS is the world's largest scientific society. Current molecular imaging approaches only detect the cancer but don't offer a method ...

Ovary removal elevates risk for Parkinson's disease and parkinsonism

...se. If an animal receives a toxic chemical able to destroy the cells of this part of the brain along with estrogen, the damage will be reduced compared to injecting the toxic substance alone." Dr. Rocca indicates that the design of the current study does not provide the data needed to address the question o...

Exercise variety - not intensity - appears to reduce some Alzheimer's disease risk

...dementia is a group of diseases that all gradually destroy brain cells and lead to progressive decline in mental function. An estimated 4.5 million Americans have Alzheimer's disease, the most common form of dementia. The number of American's with Alzheimer's disease has more than doubled since 1980 and is...

University of Nevada, Reno professor showcases 'mini' ion accelerator

...h accelerated carbon ions can pinpoint a tumor and destroy it without sacrificing surrounding tissue, making possible treatment for some cancers, such as those in the head region, that were previously untreatable. Reducing the size, and thus ultimately the cost, and improving the quality of the ion beam coul...

CML found to wield 'death factor' that kills normal blood marrow cells

... killer," he says. The secreted proteins appear to destroy bone marrow stem cells responsible for producing red blood cells as well as platelets, but leukemia cells are believed to be resistant to the effects of 24p3, the researchers found. "This provides an understanding of how Philadelphia chromosome-posit...

American Academy of Neurology sums up scientific highlights from 57th annual meeting

...Germany and New York showed that when immune cells destroy the insulating myelin around neurons, a molecule called 7-ketocholesterol is released. This molecule may stimulate other immune cells to attack the neuron. Understanding this important step may help design therapies to block it. [S12.004] Meanwhile, ...

Innovative study finds way to 'bio-synthesize' an anti-cancer compound

...atellamides through biosynthesis without having to destroy a large numbers of sea squirts in the process. The study was funded as part of a National Science Foundation (NSF) grant in the Emerging Frontiers program (Microbial Genome Sequencing). Because patellamides are small cyclic peptides (consisting of ei...

Study suggests antibiotic may limit or prevent vision problems caused by diabetes

...p crew" for the Central Nervous System (CNS). They destroy damaged cells by releasing toxins and they engulf them, much like a Pacman TM . Should they become activated and release their toxins in the retina, those toxins will kill the healthy neurons critical for normal vision. "Our studies in rats suggest t...

Saving virtual lives with nanobots goal of UH-led project

...ing and controlling a team of nanobots to seek and destroy infected tissue within a simulated terminally ill patient, a University of Houston computer science student and his teammate have advanced to the 2005 Microsoft Imagine Cup world semifinals. With two consecutive wins so far, Jonathan Dowdall, a UH ...

Active vaccine prevents mice from developing prion disease

...imal's immune system produces antibodies that will destroy them any time they appear in the body. Most vaccines in use today provide such active immunization. The prion vaccine developed at NYU would most likely first be used to protect livestock, since most prion infections occur in animals and are th...

Antibody combined with cancer drug shows promise against breast tumors

...used with docetaxel. VTAs are designed to find and destroy blood vessels within cancerous tumors, cutting off...ipid, causing the body's white cells to attack and destroy the vessels feeding the tumor. By targeting receptors unique to tumor vessels, vascular targeting ag...

Expandable electrodes safe and effective for radiofrequency ablation of liver tumors

...nerating electric current to the tumor in order to destroy it. "Expanding electrodes are different from single-tip electrodes in that all the multiple electrode tips of an expanding electrode are active so that heat distribution within the tumor is more homogeneous and a reproducible sphere of ablation is cr...

Stress may increase long-term success of vaccinations

...n their lymph nodes. T-cells are immune cells that destroy targeted pathogens. The fact that the previously stressed animals had thicker earlobes a result of the elevated levels of immune cells responding to KLH suggests that these mice had required greater immunological memory which resulted in a stronger...

JAMA study finds whooping cough vaccine effective, safe for teens and adults

...would recognize the vaccine agent as foreign, then destroy and "remember" it. When harmful versions of the pathogen later arrived, the immune system would be prepared. Reacting to a Japanese outbreak in the 1980s, pharmaceutical companies there (e.g. Takeda) designed pertussis vaccines that were based not ...

Research results from the 'Era of Hope' Department of Defense breast cancer research program meeting

...immune systems damaged by anti-cancer drugs, which destroy healthy as well as malignant cells. Women between the ages of 29 and 71 were assigned to an exercise group (28 women) or a non-exercise group (21 women). In the intervention arm, women began the exercise routine usually within a month of completing...

Exercise helps recovery from chemotherapy for breast cancer

...immune systems damaged by anti-cancer drugs, which destroy healthy as well as malignant cells. Mastro will present the research at the "Era of Hope" meeting of the Department of Defense Breast Cancer Research Program in Philadelphia, Pennsylvania, on 10 June 2005. The meeting will include presentations by M...

Tobacco linked to 63 percent of cancer death burden among African-American men

This study clarifies that the best explanation for most premature cancer deaths for African-American males is tobacco smoke exposure, whether from secondhand or active smoking. It helps estimate regional and prev...

4D proton therapy, radiation-resistant tumors, interpreting medical images

...in radiation therapy, protons offer the ability to destroy lung tumors just as competently while inflicting less damage to surrounding healthy tissue. In a small experimental patient study, researchers have increased the effectiveness of using protons to treat lung tumors. In traditional radiation therapy,...
