Malaria Parasite can Cause Severe Lymphatic Cancer

...ypically the virus is dormant, and thus relatively harmless after inserting itself into the carrier's DNA. As part of the study, researchers analysed whether CIDR1, a protein produced by the malaria parasite could reactivate EBV, by exposing the immune cells of healthy African children who had Epstein-Barr ...

Photodynamic Therapy can Scramble the Immune System to Fight Cancer Spread

...s around the world. It uses drugs that are usually harmless but become highly effective at killing cancer cells when exposed to light. Shining light on a tumour after one of these drugs has been injected selectively activates the drug in that area, treating the cancer but avoiding some of the side effects ass...

Scientists Discover Rare ‘gene-for-gene’ Interaction That Helps Bacteria Kill Their Hot

...00 cells of it are typically enough – but most are harmless to humans and can be used as a biological control mechanism to replace pesticide use. The researchers, from the universities of Bath, Bristol and Exeter, all in the UK, used the large caterpillar Manduca sexta (tobacco hornworm) to study the bacter...

World’s First Attempt To Restore Sight Using Gene Therap

... the back of the eye - using as a vehicle like a harmless virus or vector. The doctors operated first on Robert Johnson, a UK man born with a sight disorder which means he can see very little at night, and which deteriorates with age. Yet, it will be several months before the researchers know whether the...

E Coli Outbreak Forces Large-scale Recall of Beef Products

...i, or Escherichia coli, is a common and ordinarily harmless bacteria, but certain strains can cause abdominal cramps, fever, bloody diarrhea, kidney failure, blindness, paralysis and sometimes death. E. coli is found in the feces of humans and livestock. Most, but not all, E. coli infections are associated ...

Nanoparticles can Damage DNA, Increase Cancer Risk

...til we understand which types of nanoparticles are harmless and which have the potential to be harmful, I think it is prudent to limit their introduction into the environment," recommended Pacheco. Source-Eurekalert ME/V...

Scientists Receive Patent for Development of "combination" Proteins to Produce Vaccines for Lyme Disease

...isease-causing strains of bacteria from relatively harmless ones, and help assess the severity of an infection," Dunn said. Lyme disease is the most common vector-borne disease in the U.S., causing approximately 25,000 new cases each year — a rate that is expected to increase by at least a third from 2002 t...

Detection of Malignant Breast Tumors Made Simpler and More Effective

... with a non-invasive imaging method that relies on harmless light instead of X-rays, the contrast agent could help doctors diagnose disease within minutes and determine where biopsies are needed. “Because this agent is highly selective in targeting the product of malignant tumors, this approach may prove m...

Now Scientists Create a Sheep That's 15% Human

... with the possibility of silent viruses, which are harmless in animals, being introduced into the human race. Dr Patrick Dixon, an international lecturer on biological trends, warned: 'Many silent viruses could create a biological nightmare in humans. Mutant animal viruses are a real threat, as we have see...

Novel Methods in Diagnosing Oral Cancer

...ion of treatment needs at a very early, relatively harmless stage. (2) High-risk populations are clearly defined: tobacco use, alcohol abuse, urban environment, specific ethnicities, poor diet, and frequent exposure to sunlight. A fast, mobile, relatively inexpensive and non-invasive diagnostic modality wou...

Ban on Cell Phones To Be Withdrawn In Hospitals

...1 meter. They also reported that mobile phones are harmless to patients. According to Sharon Hodgson, Labour MP for Gateshead East and Washington West, the use of mobile phones give the patients a feeling of proximity with their loved ones. She also said that safety parameters should always be followed. The...

Gene Study Offers Hope of Potent Anti-cancer Drugs

..."driving" cancer development, or whether they were harmless "passenger" mutations, which accumulate in the body with age. Andrew Futreal, a senior team member at the Sanger, said some 158 driver mutations were identified in 120 of the kinase genes studied by the scientists. "It turns out that most mutatio...

Scientists Identify 120 New Cancer Genes

..."driving" cancer development, or whether they were harmless "passenger" mutations, which accumulate in the body with age, according to the researchers. They hope the study of the cancer genes will lead to the design and development of new drugs that specifically target the genetic errors that give rise to t...

Allergies Not Just for Children Anymore

...system - called// IgE - to what would otherwise be harmless substances, such as pollen, animal dander, mold, food, medication or even insect stings. In these people, their immune response overreacts by producing IgE to these substances, causing the illnesses from which they suffer. Although most often thoug...

Computer Tool Helps Pinpoint Risky Gene Mutations

...er a critical question: Is a particular mutation a harmless variation or a genetic glitch that could set the stage for cancer? In blind biochemical tests involving 36 samples containing genetic mutations whose association with breast and ovarian cancer was unknown, the computer tool demonstrated an accuracy r...

Whirling Disease Causes Culling of Thousands of Trout

...ch are several miles from both hatcheries. It is harmless to humans, but can be deadly to trout and especially Rainbow trout. According to Robert Lunsford, director of Freshwater Fisheries, it might have been spread to the hatcheries from mud on the feet of birds or bears, which are plenty in this region....

Scientists Develop a Harmless Multi-Tasking Reovirus

...chers at Oncolytics Biotech have been developing a harmless virus as a potent cancer killer//, but they have also been accumulating data that suggests in addition to directly killing tumor cells, the reovirus may prime the immune system to mount a separate, powerful and long lasting defence against cancer. ...

Garlic Hope in Infection Fight

...approach is that we may be able to render the germ harmless without killing it. If we use a conventional antibiotic, which kills the Pseudomonas, there will always be some survivors, some of which may develop antibiotic resistance. The trick is not to allow Pseudomonas to use natural selection as a weapon aga...

Activation of a Particular Brain Region Predicts Altruism: Study

...onal magnetic resonance imaging (fMRI), which uses harmless magnetic pulses to measure changes in oxygen levels that indicate nerve cell activity. The scans revealed that a region of the brain called the posterior superior temporal sulcus was activated to a greater degree when people perceived an action -- ...

Avian Flu Unlikely to Spread Through Water Systems

...V) radiation and bacterial digesters. The virus is harmless to humans but provides a study case of the pathways by which the influenza could spread to human populations. Cornell researchers studied the related virus, called H5N2, to see whether a hypothetical mutated form of H5N1 could infect people through ...
