Stimulation method helps some people with spinal cord injury to regain hand and arm mobility
Almost 18,000 Americans experience traumatic spinal cord injuries every year. Many of these people are unable to use their hands and arms and can t do everyday tasks such as eating, grooming or drinking water without help.
Using physical therapy combined with a noninvasive method of stimulating nerve cells in the spinal cord, University of Washington researchers helped six Seattle area participants regain some hand and arm mobility. That increased mobility lasted at least three to six months after treatment had ended. The research team published these findings Jan. 5 in the journal
Rockhaven Resources Ltd.: Rockhaven Discovers New Epithermal Vein Complex at Its Klaza Gold-Silver Project, Yukon
VANCOUVER, BC / ACCESSWIRE / January 13, 2021 /
Rockhaven Resources Ltd. (TSXV:RK) ( Rockhaven ) is pleased to announce the discovery of a new vein complex at its 100%-owned and road accessible Klaza property, located in the Dawson Range Gold Belt of southern Yukon. The discovery was made through reconnaissance drilling at the Rusk Target, a 2.6 sq km multi-element soil geochemical anomaly located three kilometres south of Rockhaven s Klaza Deposit. An updated PEA completed on the Klaza Deposit outlined robust economics at US$1450/oz gold and US$17/oz silver (see Rockhaven Press Release dated July 13, 2020).
Researchers develop improved process for large-scale electron microscopy to visualize small structures
How are networks of neurons connected to make functional circuits? This has been a long-standing question in neuroscience. To answer this fundamental question, researchers from Boston Children s Hospital and Harvard Medical School developed a new way to study these circuits and in the process learn more about the connections between them. Neural networks are extensive, but the connections between them are really small, says Wei-Chung Allen Lee, PhD, of the F.M. Kirby Neurobiology Center at Boston Children s and Harvard Medical School. So, we have had to develop techniques to see them in extremely high-resolution over really large areas and volumes.
New approach to tame botulinum toxin for drug delivery
While rare, botulism can cause paralysis and is potentially fatal. It is caused by nerve-damaging toxins produced by Clostridium botulinum the most potent toxins known. These toxins are often found in contaminated food (home canning being a major culprit). Infants can also develop botulism from ingesting C. botulinum spores in honey, soil, or dust; the bacterium then colonizes their intestines and produces the toxin.
Once paralysis develops, there is no way to reverse it, other than waiting for the toxins to wear off. People with serious cases of botulism may need to be maintained on ventilators for weeks or months. But a new treatment approach and delivery vehicle, described today in
Researchers identify the missing link between intestinal disease and brain injury in premature infants
Physicians have long known that necrotizing enterocolitis (NEC), a potentially lethal inflammatory condition that destroys a premature infant s intestinal lining, is often connected to the development of severe brain injury in those infants who survive. However, the means by which the diseased intestine communicates its devastation to the newborn brain has remained largely unknown.
Now, working with mice, researchers at Johns Hopkins Medicine and the University of Lausanne in Switzerland have identified that missing link an immune system cell that they say travels from the gut to the brain and attacks cells rather than protect them as it normally does.
