Study on effect of glucose on cancer growth in mice

An animal study conducted by researchers at Georgetown Lombardi Comprehensive Cancer Center raises questions about the consequences of diet - specifically glucose, the plant-based sugar that fuels cell life - on increased activity of an oncogene that drives tumor growth.

Myasthenia gravis therapies: an interview with Professor Daniel Drachman

Myasthenia gravis (MG) is an autoimmune disease that produces weakness and fatiguability of muscles. It affects between 1 and 7 people per 10,000, according to the best statistics.

Flu virus suppresses body's ability to defend against bacteria

When infected with influenza, the body becomes an easy target for bacteria. The flu virus alters the host's immune system and compromises its capacity to effectively fight off bacterial infections. Now, a team of immunologists at the Helmholtz Centre for Infection Research (HZI) and cooperation partners has discovered that an immune system molecule called TLR7 is partly to blame. The molecule recognizes the viral genome - and then signals scavenger cells of the immune system to ingest fewer bacteria.

UiO researchers discover enzyme critical for spread of cancer

Enzyme hunters at UiO have discovered the function of an enzyme that is important in the spreading of cancer. Cancer researchers now hope to inhibit the enzyme.

Pig genes resemble human genes when associated with diabetes, obesity

Insights into the genetic code of pigs that reveal how the species evolved could improve the health of animals in future.

MRC funds largest ever study of genetics relating to lung disease

Researchers from the Universities of Nottingham and Leicester are leading the largest ever study of the genetics relating to lung disease.

Smoking affects development of peripheral allergy-relevant stem cells in the blood

Environmental contaminants, such as smoking, are harmful to the human organism in relation to the occurrence of allergies. This is known. Until now, researchers had never investigated whether and to what extent environmental contaminants also affect allergy-relevant stem cells.

Viruses to treat metastatic cancers

There exists a "type" of cancer that is common yet rarely discussed—metastatic cancer, or cancer that has spread from the part of the body where it originated (the primary tumor) to another (such as lungs, bones or liver). Although much research is being done to combat primary tumors, there still exists a crucial need to find a treatment that can be effective against metastatic cancer, or "mets." Could a virus be the answer that finally beats the mets?

Tuberculosis pathogen has an ingenious defence mechanism against oxygen

Flemish biologists lead by Joris Messens (VIB / Vrije Universiteit Brussel) have discovered that Mycobacterium tuberculosis - the bacterium that causes tuberculosis - has an ingenious defence mechanism against oxygen. This knowledge is important in the search for a treatment for tuberculosis. 9.4 million people are infected with tuberculosis annually and 1.7 million people die as a result.

Potential diagnostic method to identify subset of patients with chronic fatigue syndrome

For the first time, researchers have landed on a potential diagnostic method to identify at least a subset of patients with chronic fatigue syndrome (CFS), a complex disorder with no known definitive cause or cure.

New gene delivery vehicle opens route to the heart of cells in solid tumors

There are plenty of effective anticancer agents around. The problem is that, very often, they cannot gain access to all the cells in solid tumors. A new gene delivery vehicle may provide a way of making tracks to the heart of the target.

Oscillation in brain activity influences listening process

Naturally, our brain activity waxes and wanes. When listening, this oscillation synchronizes to the sounds we are hearing. Researchers at the Max Planck Institute for Human Cognitive and Brain Sciences have found that this influences the way we listen. Hearing abilities also oscillate and depend on the exact timing of one's brain rhythms. This discovery that sound, brain, and behaviour are so intimately coupled will help us to learn more about listening abilities in hearing loss.

Ebola, Marburg and Lassa viruses must be designated as emerging diagnoses

The Ebola, Marburg and Lassa viruses are commonly referred to as emerging diseases, but leading scientists say these life-threatening viruses have been around for centuries.

Scientists eliminate metastasis in laboratory experiments

In laboratory experiments, scientists have eliminated metastasis, the spread of cancer from the original tumor to other parts of the body, in melanoma by inhibiting a protein known as melanoma differentiation associated gene-9 (mda-9)/syntenin. More than 1 million cases of skin cancer are diagnosed each year in the U.S., and melanoma is the deadliest form.

MRSA outbreak tracked and contained using DNA sequencing

Scientists have used DNA sequencing for the first time to effectively track the spread of, and ultimately contain, an outbreak of methicillin-resistant Staphylococcus aureus (MRSA), according to new research published in The Lancet Infectious Diseases.

Princeton neuroscientists to explore how human brain accomplishes real-world tasks

Princeton neuroscientists have been awarded a $4 million grant from the John Templeton Foundation to explore how the human brain enables us to pursue goals and juggle priorities in an environment full of distractions.

Research shows reduced plasticity in brains of preterm teens

New research at the University of Adelaide has demonstrated that teenagers born prematurely may suffer brain development problems that directly affect their memory and learning abilities.

Medulloblastomas that arise from different cell types might require personalized treatments

Cancers arise when a normal cell acquires a mutation in a gene that regulates cellular growth or survival. But the particular cell this mutation happens in-the cell of origin-can have an enormous impact on the behavior of the tumor, and on the strategies used to treat it.

Brevetoxin-2 stimulates nerve cell growth and plasticity in cultured mouse neurons

A new study using brevetoxin-2, a compound produced naturally by marine algae, stimulated nerve cell growth and plasticity in cultured mouse neurons. This research advances a potentially new pharmacological treatment to aid recovery of brain function following a stroke or other traumatic brain injury.

Lung cancer stem cells can be isolated and grown in preclinical models

A University of Cincinnati (UC) Cancer Institute lung cancer research team reports that lung cancer stem cells can be isolated-and then grown-in a preclinical model, offering a new avenue for investigating immunotherapy treatment options that specifically target stem cells.
