A rare but life-threatening tropical fungus that causes lung infections in both people and animals has been seen in the Pacific Northwest and could spread, researchers are reporting. The fungus, known as Cryptococcus gattii (or C. gattii), has infected dozens of humans and animals — including cats, dogs, and dolphins — in Washington and Oregon in the past five years. More

Medscape Medical News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The College of American Pathologists and the American Society of Clinical Oncology have developed a joint guideline aimed at improving the accuracy of immunohistochemical estrogen-receptor and progesterone-receptor (PgR) testing in breast cancer. The guideline has been published in both the Journal of Clinical Oncology and the Archives of Pathology & Laboratory Medicine. More

Gene silencing may be responsible for induced pluripotent stem cells' limitations
Science Daily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Scientists may be one step closer to being able to generate any type of cells and tissues from a patient's own cells. In a study that will appear in the journal Nature and is receiving early online release, investigators from the Massachusetts General Hospital Center for Regenerative Medicine and the Harvard Stem Cell Institute, describe finding that an important cluster of genes is inactivated in induced pluripotent stem cells (iPSCs) that do not have the full development potential of embryonic stem cells. Generated from adult cells, iPSCs have many characteristics of embryonic stem cells but also have had significant limitations. More

Medscape Medical News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Genetic variation in proto-oncogene MET, which has previously been linked to cancer, has for the first time been shown to influence schizophrenia risk and general cognitive ability, according to research published in the April issue of the American Journal of Psychiatry. Studies have shown that patients with schizophrenia have lower rates of cancer despite lifestyle factors, such as heavy smoking, that increase cancer risk. More

Test may let transplant patients skip biopsies
Reuters    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A gene-based blood test worked as well as a surgical procedure used to check for signs of rejection in patients with heart transplants, U.S. researchers said. They said the simple blood test called AlloMap, made by molecular diagnostics company XDx Inc, will allow heart transplant patients to forego frequent biopsies of the heart, a procedure dreaded by many transplant patients because it is uncomfortable and can damage heart valves in a few patients.

UCLA engineer invents world's smallest, lightest telemedicine microscope
UCLA    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Aydogan Ozcan, whose invention of a novel lensless imaging technology for use in telemedicine could radically transform global health care, has now taken his work a step further ― or tinier: The UCLA engineer has created a miniature microscope, the world's smallest and lightest for telemedicine applications. The microscope, unveiled in a paper published online in the journal Lab on a Chip, builds on imaging technology known as LUCAS (Lensless Ultra-wide-field Cell Monitoring Array platform based on Shadow imaging), which was developed by Ozcan, an assistant professor of electrical engineering at the UCLA Henry Samueli School of Engineering and Applied Science and a researcher at UCLA's California NanoSystems Institute.

Solving primary care shortage requires more than new health care reform law
Medscape Medical News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Imagine, for a moment, the sound of ringing telephones in physician offices in 2014, the first year most Americans are required to carry health insurance under historic health care reform legislation enacted last month. Millions of previously uninsured and undertreated individuals have just purchased policies, many with the help of tax credits, and now they are trying to make appointments with internists and family physicians to treat their migraine headaches, high blood pressure, and constipation.
