Early stage breast cancer in older women: an interview with Dr. Benjamin Smith

Early stage breast cancer in older women is a common problem. In the United States nearly half of women diagnosed with breast cancer are aged 65 or older. A sizeable proportion of those patients have early stage breast cancer.

Radiation after lumpectomy helps prevent need for subsequent mastectomy in older women with early stage breast cancer

Contrary to clinical recommendations, older women with early stage breast cancer may want to undergo radiation after lumpectomy to help ensure that they will not need a mastectomy in the future. That is the conclusion of a new study published early online in CANCER, a peer-reviewed journal of the American Cancer Society. The findings indicate that current thinking on the risks and benefits of radiation for early stage breast cancer in older women may be inaccurate.

New life for forgotten technique in detecting resistant tuberculosis

Scientists of the Antwerp Institute of Tropical Medicine have breathed new life into a forgotten technique and so succeeded in detecting resistant tuberculosis in circumstances where so far this was hardly feasible. Tuberculosis bacilli that have become resistant against our major antibiotics are a serious threat to world health.

Researchers uncover new key player in amplifying stress in early stages of diabetes

At its most fundamental level, diabetes is a disease characterized by stress—microscopic stress that causes inflammation and the loss of insulin production in the pancreas, and system-wide stress due to the loss of that blood-sugar-regulating hormone.

Self-insurance for small businesses goes under the microscope

Politco Pro describes the growing focus on this part of the insurance marketplace as a "sleeper battle to watch." Meanwhile, Reuters reports that a growing number of people are signing up for supplemental insurance coverage.

Researchers unlock genetic secrets of peripheral T-cell lymphomas

Researchers at Mayo Clinic have completed the world's first genome-wide sequencing analysis of peripheral T-cell lymphomas, unlocking the genetic secrets of this poorly understood and highly aggressive cancer of the immune system.

Malaria misdiagnosis: an interview with Dr Toby Leslie

Malaria is caused by a multi-staged parasite which is transmitted by the bite of infected female anopheles mosquitoes. It affects millions of people and kills more than 500,000 people throughout the world every year.

New tool uses fluorescence to distinguish cancerous tissue from normal one in low-grade tumors

A new probe developed collaboratively at Norris Cotton Cancer Center and Dartmouth College's Thayer School of Engineering uses an innovative fluorescence-reading technology to help brain surgeons distinguish cancerous tissue from normal tissue. The probe tool, now already in use at the Cancer Center for brain surgery, may one day be used for surgeries for a variety of cancers.

Researchers verify role of alpha-synuclein aggregates in vivo

Using a two-photon microscope capable of peering deep within living tissue, researchers at the University of California, San Diego School of Medicine have found new evidence that alpha-synuclein protein build-up inside neurons causes them to not only become "leaky," but also to misfire due to calcium fluxes.

Cadherin-catenin-actin structure exerts force inside and between cells in living tissues

If you place certain types of living cells on a microscope slide, the cells will inch across the glass, find their neighbors, and assemble themselves into a simple, if primitive tissue. A new study at Stanford University may help explain this phenomenon, and then some, about the mechanical structure and behavior of complex living organisms.

Sandia researchers develop SpinDx medical diagnostic tool

Researchers at Sandia National Laboratories have developed a lab-on-a-disk platform that they believe will be faster, less expensive and more versatile than similar medical diagnostic tools.

Microbiologists reveal how T. brucei’s key proteins organize to replicate its mtDNA

A group of diseases that kill millions of people each year can't be touched by antibiotics, and some treatment is so harsh the patient can't survive it. They're caused by parasites, and for decades researchers have searched for a "magic bullet" to kill them without harming the patient. Now, a team of microbiologists at the University of Massachusetts Amherst has made an advance that could one day lead to a new weapon for fighting parasitic diseases such as African sleeping sickness, chagas disease and leishmaniasis.

Disabling Nf1 gene makes stem cells from the third ventricle proliferate rapidly

Scientists showed in mice that disabling a gene linked to a common pediatric tumor disorder, neurofibromatosis type 1 (NF1), made stem cells from one part of the brain proliferate rapidly. But the same genetic deficit had no effect on stem cells from another brain region.

New optical microscope identifies rare breast cancer cells

The ability to distinguish and isolate rare cells from among a large population of assorted cells has become increasingly important for the early detection of disease and for monitoring disease treatments.

Cells close to death from toxin exposure can survive when toxins are removed

The vast majority of cells that appear to be on a one-way track to death after exposure to toxins can bounce back completely after those toxins are removed, Johns Hopkins scientists report in a new study. The finding, published in the June 15 issue of Molecular Biology of the Cell, is not only a testament to the indomitable cellular spirit, but could also offer some practical insight on how to save dying tissues after heart attacks or strokes as well as prevent cancer in cells transiently exposed to toxins.

Scientists successfully tag serotonin transporter to track movements of single molecules

In a process akin to belling an infinitesimal cat, scientists have managed to tag a protein that regulates the neurotransmitter serotonin with tiny fluorescent beads, allowing them to track the movements of single molecules for the first time.

UMass Amherst biochemist receives NIH grant to map molecular structure of bacterial needle

Biochemist Alejandro Heuck at the University of Massachusetts Amherst recently received a five-year, $950,000 grant from the National Institutes of Health to map the molecular structure of a needle-like tool used by deadly bacteria to drill holes in mammalian cell walls.
