New alveoli continue to be formed as lungs grow

A ground-breaking international study into the ways lungs grow and develop has challenged existing medical understanding that our lungs are completely formed by the age of three.

Researchers discover new tick-borne infection

Researchers at the University of Gothenburg's Sahlgrenska Academy have discovered a brand new tick-borne infection. Since the discovery, eight cases have been described around the world, three of them in the Gothenburg area, Sweden.

INT-777 shows promise against metabolic syndrome

Heart disease is a major cause of death in industrialised countries, and is strongly associated with obesity and diabetes. Many scientists believe that what links these conditions is a chronic, low-grade inflammation.

Report shows how mutant gene influences lipid metabolism

People who carry a malfunctioning copy of a particular gene are especially good at clearing fat from their systems. The report in the December Cell Metabolism, a Cell Press publication, shows how the mutant gene influences metabolism in this way.

Fatty livers burn more fat, not less

When our livers become loaded with fat, it isn't because they are slacking. A new study of human patients in the December Cell Metabolism shows that fatty livers actually burn more fat, not less. All that "hard work" may be at the root of the organ damage that comes with nonalcoholic fatty liver disease (NAFLD), a condition associated with insulin resistance that affects about one in three in the U.S. population.

Study evaluates whether genetic GST polymorphisms increase risk of ALD in alcoholics

It has been widely observed that only a small percentage of alcoholics develop cirrhosis of the liver, the most advanced form of alcoholic liver disease (ALD); the reason why all alcoholics do not develop such disease is not known. The present study from Spain, that includes original work and a meta-analysis, evaluates whether genetic polymorphisms that determine levels of glutathione-S-transferases (GST) relate to the risk of developing ALD among alcoholics.

Study reveals previously unseen details of SBP8a anthrax bacteriophage

A new study has shown previously unseen details of an anthrax bacteriophage - a virus that infects anthrax bacteria - revealing for the first time how it infects its host, and providing an initial blueprint for how the phage might someday be modified into a tool for the detection and destruction of anthrax and other potential bioterror agents.

Biosensors can detect oxidant production in living organism

Arterial calcification and coronary heart disease, neurodegenerative diseases such as Parkinson's and Alzheimer's, cancer and even the aging process itself are suspected to be partially caused or accelerated by oxidative stress. Oxidative stress arises in tissues when there is an excess of what are called reactive oxygen species.

Transient absorption tracks carbon nanotubes in living cells and bloodstream

Researchers have demonstrated a new imaging tool for tracking structures called carbon nanotubes in living cells and the bloodstream, which could aid efforts to perfect their use in biomedical research and clinical medicine.

GE Healthcare, UCSF collaborate for cord blood project

UCSF and the Cell Technologies business of GE Healthcare Life Sciences have begun a unique collaboration aimed at overcoming the lack of blood-forming stem cells available to patients suffering from life-threatening diseases such as lymphoma, myeloma, leukemia or sickle cell anemia.

Researchers reveal how podocytes may regenerate themselves during normal kidney function

Damage to podocytes -- a specialized type of epithelial cell in the kidney -- occurs in more than 90 percent of all chronic kidney disease. Now researchers at the Stanford University School of Medicine have uncovered an unexpected pathway that reveals for the first time how these cells may regenerate and renew themselves during normal kidney function.

Researchers identify brain area that controls voluntary movement after damage

Researchers have identified the area of the brain that controls our ability to correct our movement after we've been hit or bumped -- a finding that may have implications for understanding why subjects with stroke often have severe difficulties moving.

Fruit fly and malaria mosquito sensors attuned to heat, chemical odors

Fruit flies and mosquitoes share similar sensory receptors that allow them to distinguish among thousands of sensory cues - particularly heat and chemical odors - as they search for food or try to avoid danger, researchers from Boston College and Brandeis University report in the current electronic edition of the journal Nature.

Autism linked with disorganized structure of brain's white matter

It's still unclear what's different in the brains of people with autism spectrum disorders (ASDs), but evidence from genetic and cell studies points to abnormalities in how brain cells (neurons) connect to each other. A study at Children's Hospital Boston now provides visual evidence associating autism with a disorganized structure of brain connections, as well as defects in myelin -- the fatty, insulating coating that helps nerve fibers conduct signals and that makes up the brain's white matter.

Study reveals mechanism of action of laquinimod in patients with RRMS

Laquinimod is an orally available synthetic compound that has been successfully evaluated in phase II/III clinical studies for the treatment of relapsing-remitting multiple sclerosis (RRMS).

EMBL-EBI, BBSRC welcome UK funding announcement on behalf of life science community

The European Molecular Biology Laboratory's European Bioinformatics Institute (EMBL-EBI) and the Biotechnology and Biological Sciences Research Council (BBSRC) warmly welcome today's announcement from the UK Government of a £75 million commitment from the Department for Business, Innovation and Skills' Large Facilities Capital Fund (LFCF) for the ELIXIR research infrastructure.

Early stress of separation from biological parent impacts gene expression

Children who experience the stress of separation at birth from biological parents and are brought up in orphanages undergo biological consequences such as changes in their genome functioning, Yale School of Medicine researchers report in a new study.

DFG to establish eight new CRCs as of 1 January 2012

The Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) will establish eight Collaborative Research Centres (CRC) as of 1 January 2012. This was agreed by the responsible Grants Committee at its autumn meeting in Bonn.

Genetic variation predicts survival chances of ovarian cancer

Yale Cancer Center researchers have shown that a tiny genetic variation predicts chances of survival and response to treatment for patients with ovarian cancer.

Growth hormone PDGF-BB and blood protein EPO implicated in development of cancer

Researchers at the Swedish medical university Karolinska Institutet have demonstrated that a growth hormone, PDGF-BB, and the blood protein EPO are involved in the development of cancer tumours and that they combine to help the tumours proliferate in the body.
