Harnessing Immune System Power Heralds Next Era of Cancer Treatment

...s by which immune activating cells from humans are modified in the laboratory, and infused into patients where they will trigger other immune cells to seek out and destroy cancer. "Tumours avoid immune attack by convincing the immune system that they are normal, like a wolf in sheep's clothing," said Bramso...

New Cancer Fighting Virus

..., called NV1020, is a type of herpes simplex virus modified so that it selectively replicates in virus cells, killing them in the process. It doesnt replicate in normal, healthy cells, so our hope is that it will help fight cancers without causing side-effects in the rest of the body, said Dr. Axel Meschede...

Size and Position of Floral Anther Plays a Vital Role in Pollination

... from a plant can determine whether or not a plant modified to resist an insect pest will also have an effect on other more beneficial insects. Scientists are racing to understand these minute differences and interactions, even as habitat loss and climate change threaten the existence of many plants as well...

Contamination of the Environment by Antibiotics Fed to Livestock

...rn, lettuce, and potato. Plants were grown on soil modified with liquid hog manure containing Sulfamethazine, a commonly used veterinary antibiotic. This antibiotic was taken up by all three crops. Concentrations of antibiotics were found in the plant leaves. Concentrations in plant tissue also increased as t...

Cell Toxin Inhibits Survival Protein in Cancer Cells

...ed Hutchinson Cancer Research Center report that a modified version of antimycin called 2-Methoxy antimycin is selective in killing cells that have high levels of Bcl-2 and Bcl-xL proteins. The over expression of these proteins in many types of cancer cells correlates with resistance to chemotherapy and rad...

They came across the idea while experimenting with carbon dioxide to help boost algae growth for fish farming, This box can be used for car...

Buckyball Has the Ability to Fight Against Allergy: Research

...variety of functions. In this study, researchers modified the buckyballs so that they were attuned to water. "This discovery is exciting because it points to the possibility that these novel materials can one day lead to new therapies," said Chris Kepley, Ph.D., M.B.A., assistant professor in the Departme...

Researchers Have Found the Role of Protein in Accelerating Breast Cancer Progression

...ote breast cancer progression." Using genetically modified mouse models, the study found that the inappropriate expression of PTN produced breast cancers of a more aggressive subtype. In those same mouse models, highly malignant cells of scirrhous carcinoma-a hard, fibrous tumour-were found to express very h...

Modified Drug Therapy for Alzheimers Disease

Purdue university researchers has found a new modified drug for Alzheimers disease.The drug has begun the first phase of clinical trials. Millions of people suffer from this devastating disease and treatment options are very limited," said Arun Ghosh, the Purdue professor who led the creation of the ...

SARS Patients Experience Mental Health Decline

...ents returned to work full-time with no need for a modified schedule. At one year, 17 percent of patients had not returned to work, and a further 9 percent had not returned to their pre-SARS level of work.

Advancement in DNA Research may Bring Back Woolly Mammoth

...mammoth DNA,' he said. 'Then, by inserting this modified DNA into an elephant's egg cell, and implanting it in an elephant's womb, you could create a modified elephant that's nearly identical to the original mammoth. Or it could become possible to make entire...

'Missing Link' Stem Cells may Shorten Path to Therapies

...er species, livestock, as well as mice genetically modified to express a disease so that it can be studied, the authors of the studies said. The growth factor -- called activin/Nodal -- that is now known to work for humans and mice may also unlock access to stem cells in these other species, said Pedersen. ...

A statistical analysis was carried involving more than 18 million pregnant women; 34000 of them had suffered migraine during 2000 to 2003. There were 97 cases of stroke and a negligible number died due to brain attacks....

Protein Reduction Ceases Alzheimer's Advancement in Mice

...ournal Science, studied mice that were genetically modified to portray the symptoms of Alzheimer's disease. They found that when the production of tau was retarded, it helped prevent seizures and memory deficits associated with the disease. "Amazingly, even partial reduction of tau prevented memory proble...

Vaccine Prevents Prion Disease in Mice

For the study, the mice were orally vaccinated with a safe, attenuated Salmonella strain, which expressed the prion protein. Then they were divided into two groups those who had high levels of antibodies in their blood and th...
