Mayo Clinic scientists discover potential way to reprogram cancer cells back to normalcy

Cancer researchers dream of the day they can force tumor cells to morph back to the normal cells they once were. Now, researchers on Mayo Clinic's Florida campus have discovered a way to potentially reprogram cancer cells back to normalcy.

Researchers find that humans carry more antibiotic-resistant staphylococci than farm animals

Antibiotic-resistant bacteria are a concern for the health and well-being of both humans and farm animals. One of the most common and costly diseases faced by the dairy industry is bovine mastitis, a potentially fatal bacterial inflammation of the mammary gland (IMI). Widespread use of antibiotics to treat the disease is often blamed for generating antibiotic-resistant bacteria.

Researchers find way to screen blood samples to detect presence of precancerous polyps in the colon

Canadian researchers have found a way to screen blood samples for molecular traces that indicate the presence of precancerous polyps in the colon, a key warning sign for colon cancer. Their results, published this week in the journal Biomedical Optics Express, from The Optical Society, may yield a cheaper and less invasive initial screening test for colon cancer that could complement colonoscopy, though further clinical trials will need to demonstrate the safety and effectiveness of the blood test before it is routinely used.

BET inhibitors can cause molecular changes in neurons, lead to memory loss in mice

Cancer researchers are constantly in search of more-effective and less-toxic approaches to stopping the disease, and have recently launched clinical trials testing a new class of drugs called BET inhibitors. These therapies act on a group of proteins that help regulate the expression of many genes, some of which play a role in cancer.

FSU investigator solves cell division mystery

In the second part of his lab's recent one-two punch, Florida State University researcher Daniel Kaplan said he has solved a cell division mystery in a way that will intrigue the makers of cancer-fighting drugs.

Researchers reveal new electrical mechanism that can control molecular switches regulating cancer cell growth

The molecular switches regulating human cell growth do a great job of replacing cells that die during the course of a lifetime. But when they misfire, life-threatening cancers can occur. Research led by scientists at The University of Texas Health Science Center at Houston (UTHealth) has revealed a new electrical mechanism that can control these switches.

Physical activity improves cognitive flexibility in older adults

One day soon, doctors may determine how physically active you are simply by imaging your brain. Physically fit people tend to have larger brain volumes and more intact white matter than their less-fit peers. Now a new study reveals that older adults who regularly engage in moderate to vigorous physical activity have more variable brain activity at rest than those who don't. This variability is associated with better cognitive performance, researchers say.

Karolinska Institutet study may lead to development of better immune-based cancer therapies

A study by researchers at Sweden's Karolinska Institutet is the first to suggest that cells in the tumour blood vessels contribute to a local environment that protects the cancer cells from tumour-killing immune cells. The results, which are being published in the 'Journal of the National Cancer Institute', can contribute to the development of better immune-based cancer therapies.

Brief exposure to sudden sounds or mild trauma can form long-term memories

Researchers at NYU Langone Medical Center have found how even brief exposure to sudden sounds or mild trauma can form permanent, long-term brain connections, or memories, in a specific region of the brain. Moreover, the research team, working with rats, says it was able to chemically stimulate those biological pathways in the locus coeruleus -- the area of the brain best known for releasing the "fight or flight" hormone noradrenaline -- to heighten and improve the animals' hearing.

Veritas Genetics obtains CE mark approval for myBRCA genetic screening test

Boston-based Veritas Genetics, a pioneer in accessible genetic screening for disease prevention and early detection, received its first European CE mark approval for the company's hereditary breast and ovarian cancer genetic screening test, myBRCA. Veritas introduced myBRCA, which sequences BRCA1 and BRCA2 genes using proprietary gene-targeting technology and Next Generation Sequencing, in North America in May 2015.

Agena Bioscience releases Chip prep module to automate sample handling after PCR for MassARRAY System

Agena Bioscience today introduced the Chip prep module to automate sample handling after PCR for the MassARRAY 96-well System. This enables laboratories to operate the MassARRAY System largely unattended for high-throughput, multiplex genetic analysis.

Regen BioPharma implements gene silencing technology in killing cancer stem cells

Regen BioPharma Inc. reported today the successful implementation of its gene silencing technology, covered by patent # 8,263,571, in killing cancer stem cells.

Researchers examine relationship between energy needs and 'pleasure' of eating in food intake

A team at the Laboratoire biologie fonctionnelle et adaptative (CNRS/Université Paris Diderot) investigated the relative role of energy needs and "pleasure" of eating in food intake. The researchers studied a group of neurons in mice. They observed that when the neuron activity is compromised, feeding behavior becomes less related to the body's metabolic needs and more dependent on food palatability.

Researchers report new breakthrough in countering deadly effects of radiation exposure

An interdisciplinary research team led by The University of Texas Medical Branch at Galveston reports a new breakthrough in countering the deadly effects of radiation exposure. A single injection of a regenerative peptide was shown to significantly increase survival in mice when given 24 hours after nuclear radiation exposure.

European chestnut leaves contain ingredients with power to disarm deadly staph bacteria

Leaves of the European chestnut tree contain ingredients with the power to disarm dangerous staph bacteria without boosting its drug resistance, scientists have found.

New study shows partial genetic basis underlying racial differences in slow-wave sleep

A new study clearly establishes a partial genetic basis underlying racial differences in slow-wave sleep, suggesting that it may be possible to develop sleep-related therapies that target specific genetic variants.

MIPT scientists reveal that weak gamma radiation doses prolong life of female fruit flies

Scientists at MIPT have revealed that weak doses of gamma radiation prolong the life of drosophila flies (fruit flies), and that the effect is stronger in females than in males. These findings could reveal the genes that enable the prolongation of life and in the future lead to the creation of a means to prevent aging in humans.

Cognitive factors associated with activity, participation in everyday life among people with MS

Kessler Foundation researchers found that processing speed is the primary limiting factor associated with activity and participation in everyday life among people with multiple sclerosis (MS). "Factors that moderate activity limitation and participation restriction in people with multiple sclerosis" was published in the American Journal of Occupational Therapy.

Stanford University launches new professional education course

Imagine a world where health care is personalized, diseases are treated or even prevented before they become debilitating, and doctor's visits include regular reviews of individual genetic profiles. These are just some of the possibilities at the intersection of healthcare and genomics.

Alpha lipoic acid can stimulate telomerase with positive effects in mouse model of atherosclerosis

In human cells, shortened telomeres, the protective caps at the ends of chromosomes, are both a sign of aging and contribute to it. Scientists at Emory University School of Medicine have found that the dietary supplement alpha lipoic acid (ALA) can stimulate telomerase, the enzyme that lengthens telomeres, with positive effects in a mouse model of atherosclerosis.
