CHICAGO, IL – Outcomes after surgery have always been difficult to determine. Now a new case study on more than 500 hip procedures highlights that complication rates may be even higher than previous reports, say researchers presenting at the American Orthopaedic Society for Sports Medicine's Specialty Day in Chicago, IL.

CHICAGO, IL – Research presented today at the American Orthopaedic Society for Sports Medicine's Specialty Day in Chicago, IL shows that biceps tenodesis surgery is safe and effective for individuals who suffer a SLAP (superior labral anterior posterior) tear of the shoulder. Patients examined had previously undergone unsuccessful arthroscopic repair for their injuries.
DETROIT – Nerve mapping technology allows surgeons to determine whether surgery has been effective for relieving pressure from compressed nerves, which often function poorly and cause sciatica or pain and weakness in muscles supplied by the nerve.
In a small study involving 42 patients at Henry Ford Hospital, lead author and orthopaedic surgeon Stephen Bartol, M.D., says that mechanomyography, or MMG, is effective with measuring nerve function and determining whether nerves are compressed.
For decades researchers have recorded sounds from whales and other marine mammals, using a variety of methods including passive acoustic monitoring (PAM) to better understand how these animals use sound to interact with each other and with the environment. Now, for the first time, researchers report using this technology to record spawning cod in the wild.
In August 2011, researchers from the U.S. Department of Agriculture were presented with a serious, and potentially very costly, puzzle in Kennewick, Wash. Since Kennewick lies within a region near the heart of Washington state's $1.5 billion apple-growing region, an annual survey of fruit trees is performed by the Washington State Department of Agriculture (WSDA) to look for any invading insects. This time the surveyors discovered a crabapple tree that had been infested by a fruit fly that they couldn't identify.
The notion that each gene can only codify for a single protein has been challenged for some years. Yet, the functional outcomes that may result from genes encoding more than one protein are still largely unknown.
An international study, involving researchers from Griffith University's Eskitis Institute, hasdiscovered a molecule which could form the basis of powerful new anti-malaria drugs.
Professor Vicky Avery from Griffith University's Eskitis Institute is co-author of the paper "Quinolone-3-Diarylethers: a new class of drugs for a new era of malaria eradication" which has been published in the journal Science Translational Medicine.
Your cells are social butterflies. They constantly interact with their surroundings, taking in cues on when to divide and where to anchor themselves, among other critical tasks.
This networking is driven in part by proteins called integrin, which reside in a cell's outer plasma membrane. Their job is to convert mechanical forces from outside the cell into internal chemical signals that tell the cell what to do. That is, when they work properly. When they misfire, integrins can cause diseases such as atherosclerosis and several types of cancer.
Montreal March 22, 2013 – Determining the financial health of a company is no easy task. But new research from Concordia University's John Molson School of Business, recently published in the Journal of Corporate Finance, demonstrates that a company that revises its previous financial statements is more likely to have been poorly governed.
Certain Streptococci increase their production of toxic shock syndrome toxin 1, sometimes to potentially dangerous levels, when aerobic bacteria are present in the vagina. But scientists from the University of Western Ontario have discovered certain strains of lactobacillus bacteria are capable of dampening production of that toxin according to research published in the journal Applied and Environmental Microbiology.
PHILADELPHIA (March 22, 2013)— One molecule makes nerve cells grow longer. Another one makes them grow branches. These new experimental manipulations have taken researchers a step closer to understanding how nerve cells are repaired at their farthest reaches after injury. The research was recently published in the Journal of Neuroscience.
Catching rides on cargo ships and fishing boats, many invasive species are now covering our shorelines and compromising the existence of our native marine life.
In a study published in Ecology Letters, Northeastern University Prof. David Kimbro and his team examine what factors allow some invasive species to survive in their new environments and others to fail.
WHY SHOULD WE CARE?
DENVER – Molecular driven therapeutic targets have resulted in a paradigm shift in the treatment of advanced lung adenocarcinoma. However, in early non-small cell lung cancer (NSCLC), surgical resection remains the treatment of choice with adjuvant chemotherapy. In a recent study published in the April 2013 issue of the International Association for the Study of Lung Cancer's (IASLC) Journal of Thoracic Oncology, researchers identified patterns of mutations in early stage node negative lung adenocarcinoma.
Atherosclerosis, an inflammatory reaction, is at the root of the most common forms of cardiovascular disease. Researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have now identified a microRNA that plays a prominent role in the process, and offers a promising target for new therapies.
Philadelphia, PA, March 22, 2013 – The prevalence of obesity within the military is currently 13 percent. This rising epidemic, also rampant throughout the general population, could result in military career setbacks, negatively impact operational readiness, and jeopardize Department of Defense operations. To combat the epidemic, a team of researchers chose the military cafeteria as the venue to observe and evaluate eating behavior and the positive impact of modest changes to promote healthy eating and food selection.
