University of Notre Dame researchers have, for the first time, identified the enzymes that are detrimental to diabetic wound healing and those that are beneficial to repair the wound. There are currently no therapeutics for diabetic wound healing. The current standard of care is palliative to keep the wound clean and free of infection. In the United States, 66,000 diabetic individuals each year undergo lower-limb amputations due to wounds that failed to heal. A team of researchers from...

A crucial component of wound healing in many animals, including humans, is the migration of nearby skin cells toward the center of the wound. These cells fill the wound in and help prevent infection while new skin cells regenerate. How do these neighboring skin cells know which way to migrate? What directional cues are they receiving from the wound site? A new paper by Mark Messerli and David Graham of the MBL’s Eugene Bell Center for Regenerative Biology and Tissue Engineering clarifies...

WASHINGTON, Oct. 28, 2013 /PRNewswire-USNewswire/ -- There's a revolution going on in our understanding of the power of movement in all aspects of human life. A new book by two experienced movement analysts takes you far beyond the easily-mocked purveyors of "body language," demonstrating how the insights of today's trained movement analysts can increase our health, well-being and understanding of life in a world where more and more of our interactions are disembodied. "Movement is...

VIP Treatment For Jet Lag
2013-10-28 16:18:42

Washington University in St. Louis A brain chemical that desynchronizes the cells in the biological clock helps the clock adjust more quickly to abrupt shifts in daily light/dark schedules such as those that plague modern life A small molecule called VIP, known to synchronize time-keeping neurons in the brain's biological clock, has the startling effect of desynchronizing them at higher dosages, says a research team at Washington University in St. Louis. Far from being catastrophic,...

How Dormice Make Optimal Use Of Their Body Fat Reserves
2013-10-22 14:05:32

University of Veterinary Medicine, Vienna Edible dormice store considerable amounts of fat in summer. Their fat reserves are necessary for them to survive a long hibernation – on average 8 months – in underground cavities. But how do hibernators allocate surplus body fat reserves to optimize survival? Researchers at the Research Institute of Wildlife Ecology of the University of Veterinary Medicine, Vienna, have found that animals with larger fat reserves prefer boosting their...

Understanding The Link Between Age And Decreased Maximum Heart Rate
2013-10-15 07:29:52

[ Watch the Video: Link Between Age And Decreased Maximum Heart Rate ] April Flowers for redOrbit.com - Your Universe Online As we age, our maximum heart rate (maxHR) decreases, limiting the performance of aging athletes. Decreased maxHR is also a leading cause for nursing home admittance for otherwise-healthy elderly individuals who no longer have the physical capacity required for independent living. Until now, however, the reasons for decreased maxHR due to age have been unclear....

A simple video camera paired with complex algorithms appears to provide an accurate means to remotely monitor heart and respiration rates day or night, researchers report. The inexpensive method for monitoring the vital signs without touching a patient could have major implications for telemedicine, including enabling rapid detection of a heart attack or stroke occurring at home and helping avoid sudden infant death syndrome, according to a study published in the journal PLOS ONE. It...

Temperature Examination
2012-11-26 23:06:36

Taking a patient's temperature is an initial part of a full clinical examination. The moment the medical provider comes within inches of the patient’s skin, they can tell if there is a change in the patient’s temperature. Heat radiates from a febrile patient, skin becomes clammy when cardiac output is reduced, and cold skin can be an ominous sign when combined with other negative findings. Temperature is an important indicator for patient status. How the Temperature is Attained...

Cricothyroid ligament
2012-07-01 19:07:37

The cricothyroid ligament makes up the largest part of the laryngeal membrane, consisting of a median (anterior) and twin lateral ligaments. The median cricothyroid ligament is a flat band of white tissue joining the cricoid and thyroid cartilages. The lateral cricothyroid ligament is also known as the conus elasticus. The main function of the ligament is to keep the cricoid and thyroid from traveling too far. This ligament is cut during emergency cricothyrotomy. Image Caption: Larynx -...

Biology is the study of living organisms. Before the 19th century, biology was known as natural history (the study of all living things). Gottfried Reinhold Treviranus was the first person to coin the term biology. Biology comes from the Greek words bios (meaning "life") and logia (meaning "study of"). It is a common science that is a standard subject in schools and universities around the world. Over a million papers are published annually in biology and medicinal journals. Not just a...

The Electric eel, Electrophorus electricus, is a species of fish. It is capable of generating powerful electric shocks, which it uses for both hunting and self-defense. It is a top predator in its South American range. Despite its name it is not an eel at all but rather a knifefish. Taxonomy The species is so unusual that it has been reclassified several times. Originally it was given its own family Electrophoridae, and then placed to a genus of Gymnotidae alongside Gymnotus....
