Tinnitus, or ringing in the ears, does not appear to be a highly inherited condition (i.e., does not pass frequently from parents to offspring), according to a report in the February issue of Archives of Otolaryngology–Head & Neck Surgery, one of the JAMA/Archives journals.

Contrary to previous hypotheses, the use of non-steroidal anti-inflammatory drugs does not appear associated with risk of squamous cell skin cancer, according to a report posted online today that will appear in the April print issue of Archives of Dermatology, one of the JAMA/Archives journals.
Surgically implanted hearing aids anchored to the skull bone appear to be a durable treatment option that noticeably improves hearing among children with deafness in one ear, according to a report in the February issue of Archives of Otolaryngology -- Head & Neck Surgery, one of the JAMA/Archives journals.
INDIANAPOLIS — Indiana University School of Medicine researchers have identified a mechanism used by the tuberculosis bacterium to evade the body's immune system and have identified a compound that blocks the bacterium's ability to survive in the host, which could lead to new drugs to treat tuberculosis.
A new study from the Ottawa Hospital Research Institute (OHRI) and the University of Ottawa suggests that stem cells intentionally break their own DNA as a way of regulating tissue development. The study, published in Proceedings of the National Academy of Science (PNAS), could dramatically change how researchers think about tissue development, stem cells and cancer.
Scientists at Vanderbilt and Yale universities have successfully transplanted most of the "nose" of the mosquito that spreads malaria into frog eggs and fruit flies and are employing these surrogates to combat the spread of the deadly and debilitating disease that afflicts 500 million people.
The research is described in two complimentary papers, one published this week in the early online edition of the Proceedings of the National Academy of Sciences and the other which appeared online Feb. 3 in the journal Nature.
CINCINNATI -- Scientists have discovered a molecular pathway that works through the immune system to regenerate damaged kidney tissues and may lead to new therapies for repairing injury in a number of organs systems.
The findings, reported in this week's Proceedings of the National Academy of Sciences (PNAS), come from collaborative research led by Cincinnati Children's Hospital Medical Center and the Brigham & Women's Hospital of Harvard Medical School.
CORVALLIS, Ore. – Despite good intentions, the push to privatize government functions and insistence upon "free trade" that is too often unfair has caused declining food production, increased poverty and a hunger crisis for millions of people in many African nations, researchers conclude in a new study.
PORTLAND, Ore. — Researchers at Oregon Health & Science University have discovered a new mechanism within human cells that constantly protects us against disease. P. Michael Conn, Ph.D., a researcher at the OHSU Oregon National Primate Research Center directed the work. The findings are reported in the Feb. 15 issue of the journal Proceedings of the National Academy of Sciences.
Westchester, Ill. –A study in the Feb. 15 issue of the Journal of Clinical Sleep Medicine shows that patients with severe obstructive sleep apnea (OSA) report a significantly lower frequency of nightmares than patients with mild or no sleep apnea, indicating that OSA suppresses the cognitive experience of nightmare recall.
ANN ARBOR, Mich. — Patients with head and neck cancer linked to high risk human papillomavirus, or HPV, have worse outcomes if they are current or former tobacco users, according to a new study from researchers at the University of Michigan Comprehensive Cancer Center.
High-risk HPVs are the same viruses that are associated with cancers of the uterine cervix.
The research suggests that current or former tobacco users may need a more aggressive treatment regimen than patients who have never used tobacco.
The more specialized a hospital is in orthopedic surgical care, the better the outcomes appear to be for patients undergoing hip and knee replacement surgery, University of Iowa researchers report in a new study of Medicare patients.
Among more specialized hospitals, there were fewer serious post-surgical complications such as blood clots, infections and heart problems, as well as fewer deaths.
Drugs that target the way cells convert nutrients into energy could offer new approaches to treating a range of conditions including heart attack and stroke. Using a new way to screen for potential drugs, a team led by Massachusetts General Hospital (MGH) researchers has identified several FDA-approved agents, including an over-the-counter anti-nausea drug, that can shift cellular energy metabolism processes in animals. Their findings, being published online in Nature Biotechnology, may open the door to new therapeutic strategies for several serious health problems.
Biologists at UC San Diego have identified the specific region in vertebrates where adult blood stem cells arise during embryonic development.
Their discovery, which appears in a paper in this week's early online edition of the journal Nature, is a critical first step for the development of safer and more effective stem cell therapies for patients with leukemia, multiple myeloma, anemia and a host of other diseases of the blood or bone marrow.
Scientists funded by the Biotechnology and Biological Sciences Research Council and the British Heart Foundation at the University of Oxford have developed a revolutionary way of capturing a high-resolution still image alongside very high-speed video – a new technology that is attractive for science, industry and consumer sectors alike.
