Implantable device offers continuous cancer monitoring

Surgical removal of a tissue sample is now the standard for diagnosing cancer. Such procedures, known as biopsies, are accurate but offer only a snapshot of the tumor at a single moment in time.

Researchers discover how flu damages lung tissue

A protein in influenza virus that helps it multiply also damages lung epithelial cells, causing fluid buildup in the lungs, according to new research from the University of Alabama at Birmingham (UAB) and Southern Research Institute . Publishing online this week in the journal of the Federation of American Societies for Experimental Biology, the researchers say the findings give new insight into how flu attacks the lungs and provides targets for new treatments.

Oxygen therapy may prevent diabetics losing limbs

Researchers say on a daily basis around 275 Australians develop type 2 diabetes and worldwide, every 30 seconds a person somewhere has a lower limb amputated because of diabetic foot disease.

New brain visualization technology enables removal of fist-sized tumor

A new technology involving the fusion of four different types of images into a 3-D map of a patient's brain has helped University of Cincinnati (UC) specialists successfully remove a fist-sized tumor from the brain of an Indiana woman.

Special pathway makes bacteria vulnerable - new target for tailored antibiotics

More and more strains of bacteria are developing resistance to previously life-saving antibiotics. Researchers at TUM, the Technische Universitaet Muenchen, have shed light on a metabolic step that appears in many aggressive microorganisms -- such as tuberculosis and malaria pathogens -- and that may provide a promising target for a new class of antibiotics. The researchers present their results in the chemistry journal Angewandte Chemie.

Making the difficult task of transporting a child with special needs safer

A new study by researchers from the Automotive Safety Program at Riley Hospital for Children and Indiana University School of Medicine published online July 13, 2009 in the journal Pediatrics reports that the parents of children with special health care needs are doing a good job with the selection of the appropriate child car seat but still need help in using it correctly.

By manipulating oxygen, scientists coax bacteria into a wave

Bacteria know that they are too small to make an impact individually. So they wait, they multiply, and then they engage in behaviors that are only successful when all cells participate in unison. There are hundreds of behaviors that bacteria carry out in such communities. Now researchers at Rockefeller University have discovered one that has never been observed or described before in a living system.

Researchers profile genes in acutely ill idiopathic pulmonary fibrosis patients

The first findings from a one-of-a-kind, patient-driven effort to provide lung tissue for research might help doctors predict when patients with idiopathic pulmonary fibrosis (IPF) are becoming dangerously ill and also could point the way to interventions that could sustain them until life-saving transplants can be performed.

Frequent sex improves sperm quality

Daily sex (or ejaculating daily) for seven days improves men's sperm quality by reducing the amount of DNA damage, according to an Australian study presented today (Tuesday) to the 25th annual meeting of the European Society of Human Reproduction and Embryology in Amsterdam.

Intense cycling training damages sperm

The high-intensity training undertaken by triathletes has a significant impact on the quality of their sperm, the 25th annual conference of the European Society of Human Reproduction and Embryology heard today (Monday 29 June). Professor Diana Vaamonde, from the University of Cordoba Medical School, Cordoba, Spain, said that the triathletes who did the most cycling training had the worst sperm morphology.

Protein regulates movement of mitochondria in brain cells

Scientists have identified a protein in the brain that plays a key role in the function of mitochondria - the part of the cell that supplies energy, supports cellular activity, and potentially wards off threats from disease.The discovery, which was reported today in the Journal of Cell Biology, may shed new light on how the brain recovers from stroke.

Research leads to advanced trials of new cancer treatment

Prof. Hochberg was successful in isolating the H19 gene in humans and determining that it is significantly expressed in over 33 different forms of cancer, including superficial bladder carcinoma and pancreatic, ovarian and metastatic liver cancer, while laying dormant and non-expressed in non-cancerous cells.
