Research reveals that diarrheal bacteria can cause colon cancers

Johns Hopkins scientists say they have figured out how bacteria that cause diarrhea may also be the culprit in some colon cancers. The investigators say that strains of the common Bacteroides fragilis (ETBF) dupe immune system cells into permitting runaway colon tissue inflammation, a precursor for malignant growth.

Light-activated delivery system enhances anti-tumour drug potency

The effects of tumour-targeting drugs in mice are significantly enhanced by PCI Biotech's light-activated delivery system, a new study shows. Researchers say this dual therapy approach could be employed to increase the effect and lower the side effects of anti-cancer drugs in humans.

Discovery of the first protein-based toxin in an amphibian

Researchers in China have discovered the first protein-based toxin in an amphibian - a 60 amino acid neurotoxin found in the skin of a Chinese tree frog. This finding may help shed more light into both the evolution of amphibians and the evolution of poison.

New study suggests possible genetic link between environmental toxins and myeloma

The International Myeloma Foundation (IMF) today said newly published data may provide a possible genetic link between environmental toxins and bone disease in multiple myeloma. Myeloma, also called multiple myeloma, is a cancer of cells in the bone marrow that affect production of blood cells and can damage bone.

Discovery of possible genetic link between environmental toxins and bone disease in multiple myeloma

The International Myeloma Foundation (IMF) - supporting research and providing education, advocacy and support for myeloma patients, families, researchers and physicians - today said newly published data may provide a possible genetic link between environmental toxins and bone disease in multiple myeloma.

$3.2M grant to explore how chemicals affect human health

Most people would agree that arsenic, lead, mercury, benzene and carbon monoxide pose dangers to humans. Not many, though, realize that the average person is exposed to about 10,000 different chemicals per day.

New approach to remove toxic agent that causes myotonic dystrophy

Cell biologists from the Radboud University Nijmegen Medical Centre (Nijmegen, the Netherlands) describe a new approach to remove the toxic agent that causes the neuromuscular disease myotonic dystrophy. Their findings are published in the scientific journal The Proceedings of the National Academy of Sciences.

'Nanobee' drug delivery to tumors

When bees sting, they pump poison into their victims. Now the toxin in bee venom has been harnessed to kill tumor cells by researchers at Washington University School of Medicine in St. Louis. The researchers attached the major component of bee venom to nano-sized spheres that they call nanobees.

H5N1 avian influenza leaves people at increased risk for Parkinson's disease

At least one strain of the H5N1 avian influenza virus leaves survivors at significantly increased risk for Parkinson's disease and possibly other neurological problems later in life, according to new research from St. Jude Children's Research Hospital.

New nano-gene therapy technique could fight late-stage tumors

Tiny particles carrying a killer gene can effectively suppress ovarian tumor growth in mice, according to a team of researchers from MIT and the Lankenau Institute.

Nanoparticles show potential as part of new therapy for advanced ovarian cancer

Nanoparticle delivery of diphtheria toxin-encoding DNA selectively expressed in ovarian cancer cells reduced the burden of ovarian tumors in mice, and researchers expect this therapy could be tested in humans within 18 to 24 months, according to a report in Cancer Research, a journal of the American Association for Cancer Research.

Researchers develop new method for better diagnostic of diarrhea causing bacteria

Researchers from Helmholtz Centre for Infection Research, Germany, develop new method for better diagnostic of diarrhea causing bacteria.

Mouse model of Parkinson's reproduces non-motor symptoms

The classic symptoms of Parkinson's disease involve tremor, stiffness and slow movements. Over the last decade, neurologists have been paying greater attention to non-motor symptoms, such as digestive and sleep problems, loss of sense of smell and depression.

New discovery on how botulism paralyzes nerve cells

New structures of a botulism toxin interacting with a mimic of the nerve-cell protein it destroys suggest new ways to block this often-fatal interaction. Indeed, the mimic molecules have such high affinity for the toxin and bind to it so tightly that they themselves could possibly serve as anti-toxin drugs with further modification, the researchers said.
