Bacteria rapidly exchange genetic information related to human disease and antibiotic resistance

Much as people can exchange information instantaneously in the digital age, bacteria associated with humans and their livestock appear to freely and rapidly exchange genetic material related to human disease and antibiotic resistance through a mechanism called horizontal gene transfer (HGT).

Study examines how perception of roles among ED staff can impact patient satisfaction

A study from Rhode Island Hospital examined how the perception of roles among emergency department staff can impact patient satisfaction. Through a web survey with embedded interventions, the researchers were able to determine where gaps exist in key indicators of patient satisfaction, while staff reported changing or reconsidering how these factors play into their roles.

Articles explore clinical dilemma about children's behavioral problems

Clinicians often face the challenge of trying to make sense of conflicting reports from parents, teachers, and children about a child's behavioral problems. However, a better understanding of the source and nature of these disagreements may provide important information that could improve treatment and outcomes. A group of articles in the current issue of Journal of Child and Adolescent Psychopharmacology, a peer-reviewed journal published by Mary Ann Liebert, Inc., explores this challenging clinical dilemma.

Leeches shift the way they locate prey in adulthood

Many meat-eating animals have unique ways of hunting down a meal using their senses. To find a tasty treat, bats use echolocation, snakes rely on infrared vision, and owls take advantage of the concave feathers on their faces, the better to help them hear possible prey.

Scientists identify distinct tobacco transporter for nicotine metabolism

A team of Virginia Tech and Purdue University scientists have identified a distinct transporter used by tobacco plant cells for nicotine metabolism. The research appears in the Oct. 17 online before print issue of the Proceedings of the National Academy of Sciences (PNAS) in the article, "A tobacco nicotine uptake permease effects alkaloid metabolism."

Scientists pinpoint central elements of cell division

Scientists at Warwick Medical School have uncovered the molecular process of how cells are by-passing the body's inbuilt 'health checkpoint' with cells that carry unequal numbers of chromosomes that have a higher risk of developing cancer.

Inhibiting Notch signalling makes hormone-receptor positive cells dependent on estrogen

Within many hormone-receptor positive breast cancers lives a subpopulation of receptor-negative cells - knock down the hormone-receptor positive cells with anti-estrogen drugs and you may inadvertently promote tumor takeover by more dangerous, receptor-negative cells.

Researchers discover key enzymes that are critical for sperm function

Compared to most other cells in an organism, sperm undergo a radical transformation to become compact and mobile delivery systems for paternal DNA. Even though sperm looks and moves quite differently across species, SF State researcher Diana Chu and colleagues now say that there are at least a few key enzymes that are critical for sperm development and mobility in species as different as mice and nematode worms.

Study supports existence of metastable frequency-band-dependent scaffold of brain connectivity

Over the past two decades, the increased ability to analyze relationships among neural structures has provided novel insights into brain function. Most network approaches, how-ever, focus on static representations of the brain's physical or statistical connectivity.

Diagnostic test communication failure accounts for higher proportion of malpractice awards

Because clinical evaluation often depends on diagnostic tests, diagnostic physicians have a responsibility to notify referring clinicians when test results reveal urgent or unexpected findings.

No evidence of increased breast cancer risk for non-carriers of genetic mutations

Mothers, sisters and daughters from breast cancer families with known genetic mutations do not all share the same high risk of developing the disease, according to a new international study involving the University of Melbourne.

Hospital architecture, design and sensory stimulation make rehabilitation more effective

How does the hospital environment affect our rehabilitation? New research from the University of Gothenburg, Sweden, into how the space around us affects the brain reveals that well-planned architecture, design and sensory stimulation increase patients' ability to recover both physically and mentally. Digital textiles and multisensory spaces can make rehabilitation more effective and reduce the amount of time spent in care.

Study identifies a group of middle school students at high risk for alcohol use

Research led by University of Southern California (USC) professor Mary Ann Pentz, Ph.D., shows that black middle school students whose close friends drink alcohol are more likely to drink alcohol in high school than their white classmates.
