New biomarker highly promising for predicting breast cancer outcomes

New biomarker highly promising for predicting breast cancer outcomes

A protein named p66ShcA shows promise as a biomarker to identify breast cancers with poor prognoses, according to research published ahead of print in the journal Molecular and Cellular Biology . Continue reading

Nurse anesthetist care not equal to physician anesthesiologist-led care, comprehensive evidence-based review finds

Nurse anesthetist care not equal to physician anesthesiologist-led care, comprehensive evidence-based review finds

A recent literature review by the Cochrane Collaboration found no scientific evidence that care provided by a nurse anesthetist is as safe and effective as patient-centered, physician-led anesthesia care, prompting the American Society of Anesthesiologists (ASA®) to call for further examination to measure patient safety and anesthesia care delivery. The review, “Physician anaesthetists versus non-physician providers of anaesthesia for surgical patients,” attempted to assess the safety and effectiveness of physician-led versus nurse-led anesthesia care delivery. While the authors stated intent that they “hoped that this review may lead to an increase in confidence in the skills of NPAs nurse anesthetists within the anaesthetic community,” the comprehensive analysis could not support this premise.

Space station inspired robot to help heal sick children

Children love robots. In all shapes, sizes, “personalities” and “smarts,” these electronic wonders have been found under Christmas trees by kids and unwrapped on birthdays for years. The gift of space-inspired robotics now goes beyond toys Continue reading

Missing Protein Restored in Patients with Muscular Dystrophy

Missing Protein Restored in Patients with Muscular Dystrophy

When muscle cell membranes are damaged, the repair protein dysferlin is activated and reseals muscle membrane tears. If this repair protein is altered due to a genetic mutation, the body’s own “quality control” system (the so called proteasome) identifies the protein as being defective and eliminates it.

Do gut bacteria rule our minds?  In an ecosystem within us, microbes evolved to sway food choices

Do gut bacteria rule our minds? In an ecosystem within us, microbes evolved to sway food choices

It sounds like science fiction, but it seems that bacteria within us — which outnumber our own cells about 100-fold — may very well be affecting both our cravings and moods to get us to eat what they want, and often are driving us toward obesity. In an article published this week in the journal BioEssays , researchers from UC San Francisco, Arizona State University and University of New Mexico concluded from a review of the recent scientific literature that microbes influence human eating behavior and dietary choices to favor consumption of the particular nutrients they grow best on, rather than simply passively living off whatever nutrients we choose to send their way Continue reading

Previous pulmonary disease linked to increased lung cancer risk in large study

Links between a number of common respiratory diseases and an increased risk of developing lung cancer have been found in a large pooled analysis of seven studies involving more than 25,000 individuals. “Associations between various respiratory diseases and lung cancer have been shown in earlier studies, but few of these studies considered multiple respiratory diseases simultaneously,” said researcher Ann Olsson, PhD, of the International Agency for Research in Cancer in Lyon, France Continue reading

Beating childhood cancer does not necessarily make survivors healthier adults, study shows

Beating childhood cancer does not necessarily make survivors healthier adults, study shows

Having survived cancer as a child does not necessarily have a ripple effect that makes people lead a healthier lifestyle once they grow up. In fact, in a report derived from a National Cancer Institute-funded study of childhood cancer survivors known as the Chicago Healthy Living Study, investigators found that childhood cancer survivors in no way adhere more closely to guidelines on healthy eating than their cancer-free peers.

Like cling wrap, new biomaterial can coat tricky burn wounds, block out infection


Like cling wrap, new biomaterial can coat tricky burn wounds, block out infection


Wrapping wound dressings around fingers and toes can be tricky, but for burn victims, guarding them against infection is critical. Today, scientists are reporting the development of novel, ultrathin coatings called nanosheets that can cling to the body’s most difficult-to-protect contours and keep bacteria at bay. The researchers are speaking about their materials, which they’ve tested on mice, at the 248th National Meeting & Exposition of the American Chemical Society (ACS), the world’s largest scientific society Continue reading

Pregnant women, fetuses exposed to antibacterial compounds face potential health risks 


As the Food and Drug Administration (FDA) mulls over whether to rein in the use of common antibacterial compounds that are causing growing concern among environmental health experts, scientists are reporting today that many pregnant women and their fetuses are being exposed to these substances.
