Genomic tests help in selecting the most effective therapy for breast cancer

Genomic tests that determine the molecular subtype of a woman's breast cancer provide a more precise prognosis and valuable guidance about the best treatment, according to new research led by Massimo Cristofanilli, M.D, Director of the Jefferson Breast Care Center at the Kimmel Cancer Center (KCC) and Thomas Jefferson University and Hospitals.

Bioethics Commission releases ethical recommendations to manage incidental and secondary findings

Researchers conduct a memory study, scan a participant's brain, and find more than they bargain for: a tumor. What do the researchers owe the participant? What does the participant want to know?

Transport of bacterial substrates through injectisome observed almost in real time

When attacking body cells, bacteria, such as salmonellae or Yersinia (plague pathogens), inject specific bacterial proteins through hollow, syringe-like structures - called injectisomes - into the host cells. These substances reprogram the cells and can thus overcome their defense. From then on, they can infiltrate the cells unhindered in large numbers, and trigger diseases such as typhus, plague, or cholera.

Researchers uncover second rare genetic mutation linked to higher risk of Alzheimer's disease

A research team from The University of Nottingham has helped uncover a second rare genetic mutation which strongly increases the risk of Alzheimer's disease in later life.

Novel ISM strategy enables selection of potentially effective cancer therapies for patients

A new individualized systems medicine strategy, developed at the Institute for Molecular Medicine Finland FIMM and the Helsinki University Central Hospital, enables a selection of potentially effective cancer therapies for individual patients. The promising results achieved by applying this strategy to chemoresistant adult acute myeloid leukemia patients have been recently published in the Cancer Discovery journal.

Protein in Salmonella inactivates mast cells that fight against bacteria

A protein in Salmonella inactivates mast cells -- critical players in the body's fight against bacteria and other pathogens -- rendering them unable to protect against bacterial spread in the body, according to researchers at Duke Medicine and Duke-National University of Singapore (Duke-NUS).

Study: Antisense drugs show activity in wide range of tissues and organs

Antisense therapeutics, a class of drugs comprised of short nucleic acid sequences, can target a dysfunctional gene and silence its activity. A new study has shown that antisense drugs delivered systemically show activity in a wide range of tissues and organs, supporting their broad therapeutic potential in many disease indications, as described in an article in Nucleic Acid Therapeutics, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

Names of 2014 Breakthrough Prize winners in Fundamental Physics and Life Sciences unveiled

The names of the 2014 Breakthrough Prize winners in Fundamental Physics and Life Sciences were unveiled at an exclusive ceremony at the NASA Ames Research Center, Mountain View, CA. At a total awarded amount of $21 million, sponsored by Sergey Brin & Anne Wojcicki, Jack Ma & Cathy Zhang, Yuri & Julia Milner and Mark Zuckerberg & Priscilla Chan, the prizes aim to celebrate scientists and generate excitement about the pursuit of science as a career.

Research findings could provide better understanding of anxiety disorders

In a new study published today in Science, John McGann, associate professor of behavioral and systems neuroscience in the Department of Psychology, and his colleagues, report that neurons in the noses of laboratory animals reacted more strongly to threatening odors before the odor message was sent to the brain.

Scientists bring stem cell science directly to patients

Scientists from UCLA's Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research are bringing stem cell science funded by the California Institute of Regenerative Medicine (CIRM), the state stem cell agency, directly to patients in two exciting new clinical trials scheduled to begin in early 2014.

Gene Expression Barcode 3.0 tool proves to be a vital resource for cancer research

A newly improved internet research tool is helping cancer researchers and physicians make sense out of a deluge of genetic data from nearly 100,000 patients and more than 50,000 mice.

UCSB anthropologists find successful hunting boosts testosterone, cortisol levels in Tsimane men

While small-scale horticulture is a relatively recent addition to the human repertoire of food provisioning, hunting has deep evolutionary roots. In practically every society, hunting ability correlates with reproductive success - the better the hunter, the more children he is likely to father.

UCLA stem cell researchers track early development of human articular cartilage

Stem cell researchers from UCLA's Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research have published the first study to identify the origin cells and track the early development of human articular cartilage, providing what could be a new cell source and biological roadmap for therapies to repair cartilage defects and osteoarthritis. These revolutionary therapies could reach clinical trials within three years.

More outreach needed for family members who carry genetic risks of cancer

A study done by researchers at Fox Chase Cancer Center shows that many relatives of patients who undergo testing for a gene linked to breast and ovarian cancers misinterpret the results, and less than half of those who could benefit from genetic testing say they plan to get tested themselves-despite the fact that knowing your genetic status may help catch the disease in its earliest stages.

New study provides a set of tools for measuring age in all dimensions

Age is not just the number of years one has lived, argue IIASA population researchers. A new study from the group provides a set of tools for measuring age in all its dimensions.

Study: Immune cells outside the brain may regulate propensity to develop depression

A new study shows that immune cells outside the brain may regulate propensity to develop depression. The data were presented today at the American College of Neuropsychopharmacology Annual Meeting.

University of Colorado medical school professor uncovers variant of NKH

People from around the country and the world turn to Johan Van Hove, MD, PhD, for advice on a rare metabolic disease known as NKH, which can disrupt the body in devastating and even deadly ways. Now, Van Hove, a University of Colorado medical school professor, has identified a new disease related to NKH, a finding that resolves previously baffling cases including the death of a Colorado girl.

New treatment needed for women with HER2- and hormone receptor-positive breast cancer with PIK3CA mutation

Women with breast cancer characterized by high levels of the protein HER2 and hormone receptors gained much less benefit from presurgery treatment with chemotherapy and HER2-targeted therapies if their cancer had one or more mutations in the PIK3CA gene, according to results presented here at the 2013 San Antonio Breast Cancer Symposium, held Dec. 10-14.

Researchers discover easy-to-use method for bonding gels and biological tissues

Researchers have discovered an efficient and easy-to-use method for bonding together gels and biological tissues. A team headed by Ludwik Leibler, involving researchers from the Laboratoire Matière Molle et Chimie (CNRS/ESPCI ParisTech) and the Laboratoire Physico-Chimie des Polymères et Milieux Dispersés (CNRS/ UPMC/ESPCI ParisTech), has succeeded in obtaining very strong adhesion between two gels by spreading on their surface a solution containing nanoparticles.

Researchers show biophysical factors that contribute to the strength of heartbeat

The heart maintains a careful balancing act; too soft and it won't pump blood, but too hard and it will overtax itself and stop entirely. There is an optimal amount of strain that a beating heart can generate and still beat at its usual rate, once per second.
