E-NTPDase2 quickly latches on to ATP converting it to ADP. This meant that where and when the researchers introduced ...

Understanding hypertension in African Americans proves elusive

... study, he found that the level of aldosterone was related to how the two racial groups distributed body fat. Caucasians generally stored fat in the abdomen area, whereas African Americans had fat distributed throughout the body in a layer under the skin. The six-month study involving 35 Caucasians and ...

Magnetic system could be key to surgery without scars

The system uses a stack of magnets outside the abdomen to attract other magnets attached to laparoscopic instruments inside the ... may solve the fundamental problem of guiding instruments through the abdomen for natural orifice surgery, which now inserts the instruments through the ...

pHLIP, a novel technology to locate and treat tumors

... National Academy of Sciences. The researchers show that, the protein fragment, called “pHLIP?(pH (Low) Insertion Peptide) can be injected into the abdomen of a mouse, find its way into the blood and then specifically accumulate in tumors. Within 20 hours after injection of labeled pHLIP, the molecules ...

Students invent protective pouch to enhance cell therapy

Using real-time imaging technology, an interventional radiologist can view and guide the minimally invasive ...

UW launches study testing adult stem cells for heart damage repair

... disease and the severity of the pain. Next, all subjects receive a series of needle shots, typically delivered under the skin in the arm, thigh or abdomen of a commercially produced protein (granulocyte colony stimulating factor). The protein helps to release blood-forming CD34+ cells from a subject's ...

Breathing easy: When it comes to oxygen, a bug's life is full of it

... how the system works. Insects employ autoventilation (using wings or legs to pump air through the body), abdominal pumping (using the muscles in the abdomen to pump air), and tracheal compression (getting oxygen to the head and thorax). ...

Tarantulas produce silk from their feet

... spigots on their legs, allowing them to better cling to surfaces. Until now, spiders were only known to spin silk from spinnerets located on their abdomen and to use the silk to form webs for protection and capturing prey rather than for locomotion. The findings are published in the current issue of ...

MIT engineers probe spiders' polymer art

Falling ants glide back to trunk to avoid dangers of forest floor

... earlier observations combined with the videotaped tests in Panama established that the ants basically reorient their bodies so their hind legs and abdomen point toward the tree, and use their head-up fall through the air to take them feet-first toward the trunk. How they land is still a mystery, but ...
