Association Between Regional Anesthesia And Postoperative Pain Relief

Researchers explore the evolution of regional anesthesia and the impact of technology on its development. Since the first general anesthesia (GA), anesthesia has seen a rapid evolution. In tandem with advances in pharmacology, anesthesia techniques were developed to facilitate surgical procedures and to increase patient safety.

Besides GA, regional anesthesia (RA) was introduced in the late 19th century when K. Koller used cocaine as a local anesthetic and W. Halsted performed the first peripheral nerve block (PNB) by infiltrating a local anesthetic (LA) solution around the nerve, making a transmission for sensation and pain impossible.

Super-Resolution Imaging Tissue Of Alzheimer’s Disease

A study developed super-resolution nanoscope.,The device not only presents a 3D view of the molecules in the brain, but it does so at a resolution ten times higher than anything that has gone before. It is hoped that this new imaging technique will offer vital insight into the progression of the disease and lead to new treatments.

Tackling Alzheimer’s disease is a multifaceted issue, but among the biggest obstacles to overcome is not being able to see the origins of the condition. Already, there is a change as a result of the instrument. Scientists at Indiana University have used it to understand better the plaques that form in the brain of patients with Alzheimer’s. They were able to pinpoint characteristics with the potential to be the cause of the damage.

Hidden Signals In RNAs That Regulate Protein Synthesis

Researchers have known that RNA encodes instructions to make proteins. The building blocks that comprise RNA-; A, U, C, and Gs-; form a blueprint for the protein-making machinery in cells. To make proteins, the machinery latches on RNA at one end and then scans along the RNA until it reaches an AUG string, which is the signal to start translating the genetic code into a protein. The study was published in Nature.
