Cartilage discovery offers arthritis hope

...ucture of cartilage in what they hope will provide clues to how the crippling joint disease osteoarthritis might one day be treated. The disease, which affects more than five million people in the UK, is caused by the wear and tear of the smooth, hard cartilage tissue that covers the ends of bones allowin...

Scientists sequence genome of parasite responsible for common sexually transmitted infection

...transmitted infections (STIs), revealing potential clues as to why the parasite has become increasingly drug resistant and suggesting possible pathways for new treatments, diagnostics and a potential vaccine strategy. The genome sequencing project, funded by the National Institute of Allergy and Infectious...

Cancer vaccines -- Taking a jab at cancer by stimulating the immune system

...e I study of a pancreatic cancer vaccine may offer clues toward promoting long-term survival from the disease, according to researchers from the University of Pittsburgh Cancer Institute. The researchers gave a dendritic cell vaccine to 12 pancreatic cancer patients. Four of the subjects have shown no ...

Paleontologists discover new mammal from Mesozoic Era

...ts have been searching for more than a century for clues to the evolutionary origins of mammal ear structure. Mammalian hearing adaptation is made possible by a sophisticated middle ear of three tiny bones, known as the hammer (malleus), the anvil (incus) and the stirrup (stapes), plus a bony ring for t...

Scientists map key landmarks in human genome

...ome. The mapping tool could help uncover important clues for understanding and diagnosing cancer and other ...n genome. The new technique "provides major new clues to the locations of many hallmark features of the human genome, such as where transcription factors ...

Study uncovers a lethal secret of 1918 influenza virus

...e response may provide biomedical researchers with clues about how to intervene and stop or mitigate the virus' potentially lethal effects, Kawaoka says. "Things may be happening at an early time point (in infection), but we may be able to step in and stop that reaction."...

Scientists perform 'tricky' operation

... project to sequence the genome, which could offer clues to better treatments for both men and women. Ms Dunne said the results would allow researchers to hone in on genes and gene families of interest, particularly those involved in drug resistance. "The completion of the genome sequence by The Inst...

Primitive yeast yields secrets of human cholesterol and drug metabolism

... the genetic blueprint coding for Dap1 may provide clues to how and why different people react differently to certain drugs. “Understanding the molecular underpinnings of so-called pharmacogenetic variation will have a big impact on the future of medicine,?he says....

Prehistoric mystery organism verified as giant fungus

...n said. "Fran spent months deciphering them for clues about the localities where specimens had been collected, how Dawson interpreted them and other information that helped understand this humongous fungus," she said. Hueber also traveled to Canada, Australia and Saudi Arabia to collect specimens. He...

Protein key to organ growth

...ntrolling growth and differentiation, and may give clues to treatment of a particular benign disease called tuberous sclerosis that is associated with the control exerted through the same pathway, said Dr. Kwang-Wook Choi, associate professor of molecular and cellular biology at BCM and his colleagues. ...

Pacific Rim researchers to collaborate on distributed bioinformatics analysis of avian flu

...es as well as the signal transduction pathways for clues to understanding how avian flu interferes with human metabolism." The Asian institutions ?all members of PRAGMA ?will host some U.S. students and researchers, while taking responsibility for specific tasks: JLU will support the scheduling of ...

Fruit fly gene research may shed light on human disease processes

... pests—they may be allies in a fruitful search for clues to human diseases caused when genes malfunction. "One common misconception is that individual humans may carry 'disease-causing' genes, such as a gene for cancer," explains James Erickson, a biology professor at Texas A&M University. "All human...

How fish conquered the ocean

...Yet it was this paradox that provided the trail of clues for us to follow". "The physiological problems of reverting from a fresh water environment to the saline seawater is demanding for the water balance of fishes", says professor Hans Jørgen Fyhn, a colleague of Dr. Finn, and adds, "This is especiall...

Breathing easy: When it comes to oxygen, a bug's life is full of it

...s and air sacs in living insects that give further clues to how the system works. Insects employ autoventilation (using wings or legs to pump air through the body), abdominal pumping (using the muscles in the abdomen to pump air), and tracheal compression (getting oxygen to the head and thorax). ...

Invasive ants territorial when neighbors are not kin

...ehavior. Nor were there any obvious environmental clues to explain why ants would attack ants of the same species from one neighboring nest but not another. However, the researchers found a very close relationship between behavior and genetics. Ants that were genetically similar had peaceful relations. ...

Harvard scientists identify compounds that stimulate stem cell growth in the brain

...2006 issue of The FASEB Journal, provide important clues as to which compounds may be responsible for causing key brain cells, neurons, to regenerate and ultimately restore brain function. The research study focused on two compounds--LTB4 and LXA4. Both play a role in inflammation and are regulators of p...

New clues to how sex evolves

...he University of California at Berkeley have found clues to one part of this complex question in ongoing studies of the nematode Caenorhabditis elegans. Abby Dernburg, of Berkeley Lab's Life Sciences Division and UC Berkeley's Department of Molecular and Cell Biology, working with graduate student Caroly...

Tiny Tampa Bay fish key to evolution of immune system

...ms are positioned in the protein's core, providing clues as to which atoms are participating in key stabilizing interactions. Doctors often use infusions of antibodies to bolster immune systems weakened by cancer or other conditions, but ironically, these proteins are susceptible to enzymes that break th...

Tarantula venom and chili peppers target same pain sensor

... channels of the nervous system work. They give us clues as to how specific activators or blockers on these channels can be designed to treat persistent pain ?from arthritis, bladder infections, or other diseases." The researchers determined the venom peptides' effect in neuron cell cultures, measuring t...

Discovery of the first resistance gene to rice yellow mottle virus

...virus. Understanding of these mechanisms will give clues as to the best ways of making long-term use of this resistance gene. Another strategy developed by the IRD for combating this virus involves introducing part of the viral genes into the plant genome by transgenesis, as has been done in other plant...
