U of MN research indicates why radiation therapy reduces bone cancer pain
...tion dose decreased painful behavior and increased limb
use, which was associated with a decrease in bone destruction and tumor burden. Treated mice demonstrated greater pain relief and had significantly less bone destruction and tumor burden than untreated mice. Recent studies have demonstrated that tu...
Study moves in on why astronauts suffer bone loss
...receptor signaling system inside the cell." When a limb
is immobilized in a cast, when an astronaut experiences zero gravity, or whenever a person lies down, the weight-bearing bones of the body such as those in the spine and leg, are relieved of their burden, a condition known as skeletal unloading. When...

Study will identify best treatment for type 2 diabetes in youth
...diabetes. It is the main cause of kidney failure, limb
amputations, and new onset blindness in adults and is a major cause of heart disease and stroke. Type 2 diabetes, most common in adults over age 40, accounts for up to 95 percent of all diabetes cases. The prevalence of type 2 diabetes has risen dr...
Researchers say stenting the best treatment for blocked leg arteries
...at gangrene develops or amputation of the affected limb
is necessary. Until the introduction of the stent, a small metal tube, 10 years ago, the only way to open up such vessels was surgically, bypassing the blockage with a healthy vein or artery. Increasingly, interventional radiologists are treating th...
Study finds nerve damage can affect opposite side of body
... "This loss of nerve fibers in the contralateral limb
is so precise being confined to areas innervated by the matching nerve that the communication is likely to involve nerve cells or the supporting glial cells," says Oaklander, an assistant professor of Anesthesia and Neurology at Harvard Medical Sch...
Two-stage weight loss surgery for high-risk, morbidly obese patients reduces surgical risk

Ultrasound treatment for hurt muscles may feel good, but doesn't promote healing, study suggests
...ick," Devor said. The researchers treated one hind limb
on each rat with ultrasound daily for seven days for five minutes per session. Ultrasound waves were transmitted through a small wand that was rubbed along the rats' limbs. The other limb, used as the control, was left to recover on its own. Rats wer...
Successful therapy for head and neck cancer may lead to long-term circulatory problems
...cerine. The integrity of the cardiovagal efferent limb
of the baroreflex was measured through power spectral analysis of heart rate variability during slow, deep respiration. To test the sympathetic noradrenergic limb, the researchers observed blood pressure and heart rate during the cold pressor test. ...
Parkinson's drug effective in treating restless leg syndrome
...ficacy measures were sleep efficiency and periodic limb
movements during sleep (PLMS). Severity of RLS was assessed by the validated International RLS Scale. In phase one, pergolide reduced PLMS arousal index versus placebo and improved RLS severity scores, though it did not improve sleep efficiency. Pati...

New understanding of neural circuits may help development of thought-controlled prosthetic devices
... leg, or foot. An injury that causes the loss of a limb
or damage to the spinal cord can sever this communication line and prevent desired movement. In theory, a thought-controlled prosthetic device, also known as a brain-machine interface, could bypass the loss or damage by directly interpreting nerve ce...
Exercising limbs protects brain cells affected by Parkinson's, study in rodents shows
