Georgia State researcher discover new process to make one-time flu vaccine

A new process to make a one-time, universal influenza vaccine has been discovered by a researcher at Georgia State University's Center for Inflammation, Immunity and Infection and his partners.

Tumor cells manipulate unfolded protein response

Researchers at the University of California, San Diego School of Medicine report that tumor cells use stress signals to subvert responding immune cells, exploiting them to actually boost conditions beneficial to cancer growth.

Targeting km23-1 protein may slow the spread of cancer cells

The spread of cancer cells may be slowed by targeting the protein km23-1, according to researchers at Penn State College of Medicine.

Budding yeast an acceptable model system to study KP1019 anti-cancer drug

Researchers have found that the budding yeast (Saccharomyces cerevisiae) is an acceptable model system to study KP1019, an anti-cancer drug that uses ruthenium, a rare metal, a new study found. Researchers had previously been interested in studying KP1019 because it is believed to cause cancer cell death and is not known to have negative secondary side effects for healthy tissues.

Metallic probe can detect fibrils from misfolded proteins in real time

Rice University scientists have discovered a new way to look inside living cells and see the insoluble fibrillar deposits associated with Parkinson's disease.

Study: Purines fend off damage during anesthesia

Anesthesia is quite safe these days. But sometimes putting a patient under to fix one problem, such as heart damage, can harm a different organ, such as a kidney.

Changes in cholesterol metabolism induced by diet can alter the gut flora

For more than half a century, researchers have known that the bacteria that colonize the gastrointestinal tract of mammals influence their host's cholesterol metabolism. Now, Jens Walter and colleagues of the University of Nebraska show that changes in cholesterol metabolism induced by diet can alter the gut flora.

Myostatin responsible for initiation of muscle loss: Study

A research study from Nanyang Technological University (NTU) has yielded important breakthroughs on how the body loses muscle, paving the way for new treatments for aging, obesity and diabetes.

MiR-122 plays a critical role in the life cycle of hepatitis C virus

Hepatitis C virus has evolved to invade and hijack the basic machinery of the human liver cell to ensure its survival and spread. Researchers at the University of North have discovered how hepatitis C binds with and repurposes a basic component of cellular metabolism known as a microRNA to help protect and replicate the virus.

Link between silent stroke and Parkinson's disease

Scientists at The University of Manchester have for the first time identified why a patient who appears outwardly healthy may develop Parkinson's disease.

Study investigates biology of emotional sharing

Therapists have long known that people who've had a traumatic experience feel the need to talk about what they've been through. This process is called 'social sharing' and can take place for days, weeks, months or years after the event.

Scientists decode VEGF/Ang1/Syx pathway that regulates leakiness of blood vessels

A research team led by scientists at Mayo Clinic in Florida have decoded the entire pathway that regulates leakiness of blood vessels — a condition that promotes a wide number of disorders, such as heart disease, cancer growth and spread, inflammation and respiratory distress.

BubR1 and its associated regulators promising targets for aging disorders and cancer

A new series of studies in mouse models by Mayo Clinic researchers uncovered that the aging process is characterized by high rates of whole-chromosome losses and gains in various organs, including heart, muscle, kidney and eye, and demonstrate that reducing these rates slows age-related tissue deterioration and promotes a healthier life span. The findings appear in today's online issue of Nature Cell Biology.

CNIO creates 2 new databases to study the human genome

Scientists from the Structural Computational Biology Group at the Spanish National Cancer Research Centre (CNIO), led by Alfonso Valencia, together with French and American researchers, have published recently two articles in the journal Nucleic Acid Research (NAR) that introduce two new databases for studying the human genome.

MiR-181 molecule tied to breast cancer metastasis

Researchers at Case Western Reserve University School of Medicine have identified a molecule linked to more aggressive forms of breast cancer - a discovery that could point the way to potential cures.

High AngII levels put stress on the ER and cause hypertension

When the heart works too hard, the brain may be to blame, says new Cornell University research that is changing how scientists look at high blood pressure (hypertension). The study, published in the Journal of Clinical Investigation in November, traces hypertension to a newfound cellular source in the brain and shows that treatments targeting this area can reverse the disease.

Bullying among children may be a threat to their future mental health

A recent study by a researcher at the Centre for Studies on Human Stress (CSHS) at the H-pital Louis-H. Lafontaine and professor at the Universit- de Montr-al suggests that bullying by peers changes the structure surrounding a gene involved in regulating mood, making victims more vulnerable to mental health problems as they age.

Advanced MRI can non-invasively evaluate cellular proliferation of tumor models of breast cancer

Scientists at the University of Arizona Cancer Center and the Moffitt Cancer Center, led by Dr. Robert Gillies, have demonstrated that an advanced magnetic resonance imaging (MRI) method can non-invasively evaluate the cellular proliferation of tumor models of breast cancer.
