Severity of smoke-inhalation injury may play a role in overall pulmonary inflammatory response

A study of burn patients has found that those who suffered the most severe smoke inhalation also had more inflammation and spent more time on ventilators and in intensive care.

Cancer cells tap into natural recycling system to obtain energy

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered that cancer cells tap into a natural recycling system to obtain the energy they need to keep dividing. In a study with potential implications for cancer treatments, Einstein researchers used genetic manipulation to turn off this recycling system within the walls of cells and stop both tumor growth and metastasis.

Potential breakthrough in treating late-stage ovarian cancer

A potential breakthrough in treating late-stage ovarian cancer has come from University of Guelph researchers who have discovered a peptide that shrinks advanced tumours and improves survival rates for this deadly but often undetected disease.

Diallyl trisulfide may protect heart after attack

A component of garlic oil may help release protective compounds to the heart after heart attack, during cardiac surgery, or as a treatment for heart failure.

New 2-DG-ABT combination cancer therapy triggers apoptosis

Researchers at the University of California, San Diego School of Medicine and Kyushu University Medical School say a novel combination of a specific sugar molecule with a pair of cell-killing drugs prompts a wide variety of cancer cell types to kill themselves, a process called apoptosis or programmed cell death.

Researchers identify potential marker for leukemic relapse

The development of simple tests to predict a leukemic relapse in young patients is a step closer thanks to researchers from the Sainte-Justine University Hospital Research Center and the University of Montreal. Approximately 20 percent of young leukemia patients who are treated with stem cells derived from umbilical cord blood will experience leukemic relapse.

SHARPIN protein regulates human cell activity

The research teams headed by Prof. Johanna Ivaska (University of Turku and VTT Technical Research Centre of Finland) and Prof. Marko Salmi (University of Turku and the National Institute for Health and Welfare) have discovered that the SHARPIN protein regulates human cell activity.

Link between NRXN3 gene and impulsivity

Being impulsive can lead us to say things we regret, buy things we really don't need, engage in behaviors that are risky and even develop troublesome addictions. But are different kinds of hastiness and rashness embedded in our DNA? A new study suggests the answer is yes -- especially if you're a man.

Breakthrough in loading gold nanorods into cells could lead to new cancer treatment

Rice University chemists have found a way to load more than 2 million tiny gold particles called nanorods into a single cancer cell. The breakthrough could speed development of cancer treatments that would use nanorods like tiny heating elements to cook tumors from the inside.

Dipyrone may reduce brain damage after stroke

An older nonsteroidal anti-inflammatory drug (NSAID) called dipyrone may offer a new approach to reducing injury to brain tissue after a stroke, according to a study in the October issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Budding yeast helps make useful predictions about the biology of individuals

It now only costs a few thousand Euros to sequence the genome of an individual human. However, for most of us, knowing our genome sequence would not be useful. Each human has more than 20 000 genes, and in each of us several thousand of these genes carry mutations.

Non-therapeutic antibiotic usage in food animals creates resistance genes, promotes antibiotic resistance

In a review study, researchers from Tufts University School of Medicine zero in on the controversial, non-therapeutic use of antibiotics in food animals and fish farming as a cause of antibiotic resistance.

Coronary calcium scoring can determine risk of cardiac events

If your doctor says you have a negative stress test, or that your cholesterol or blood pressure are normal, how assured can you be that you're not likely to have a heart attack in the next seven to 10 years?

Insulin sensitivity in the ovaries and the pituitary linked to infertility

Infertility is common among obese women, but the reasons remain poorly understood and few treatments exist. Now a team of Johns Hopkins Children's Center scientists, conducting experiments in mice, has uncovered what they consider surprising evidence that insulin resistance, long considered a prime suspect, has little to do with infertility in women with type-2 diabetes, polycystic ovary syndrome and metabolic syndrome, all obesity-related conditions.

Human pluripotent stem cells rely heavily on glycolysis to drive their metabolic activities

Human pluripotent stem cells, which can develop into any cell type in the body, rely heavily on glycolysis, or sugar fermentation, to drive their metabolic activities.
