The coming of age of gene therapy: A review of the past and path forward

A new gene is injected into an adenovirus vector, which is used to introduce the modified DNA into a human cell. If the treatment is successful, the new gene will make a functional protein. After three decades of hopes tempered by setbacks, gene therapy -- the process of treating a disease by modifying a person's DNA -- is no longer the future of medicine, but is part of the present-day clinical treatment toolkit. The Jan. 12 issue of the journal Scienceprovides an in-depth and timely review of the key developments that have led to several successful gene therapy treatments for patients with serious medical conditions...More Source: https://www.sciencedaily.com/releases/2018/01/180111141553.

New technology detects the 'glow' to guide brain tumor resection

Research by Barrow Neurological Institute physicians and University of Washington scientists on novel imaging technology for malignant brain tumors was published in the April issue of World Neurosurgery. The research was conducted by Drs. Evgenii Belykh and Mark Preul at the Barrow Neurological Institute Neurosurgery Research Laboratory with technology developed by Drs. Eric Seibel and Leonard Nelson from the Department of Mechanical Engineering and the Human Photonics Laboratory at the University of Washington. At Barrow they used a Scanning Fiber Endoscope (SFE) to detect the glow produced by adding the pro-drug 5-ALA to experimental models of malignant brain tumors. 5-ALA is metabolized i

New imaging system makes back surgery safer, faster and less expensive

Researchers at Dartmouth College have found a way to make back surgery safer, faster and more cost effective. MRIs and CT scans help surgeons identify spine problems, like compressed vertebrae or herniated disks, but finding a clear path to those problem areas is not always as straightforward. Tissue and bone not only stand in the way, they can also move during spinal surgery, rendering a CT scan taken prior to surgery much less accurate. To solve this problem, Dartmouth professors from the Thayer School of Engineering and the Geisel School of Medicine developed a 3-dimensional, real-time optical tracking system to guide back surgeons as they operate, like a Google Maps for the body, accordi

First-in-world robot-assisted spinal surgery

Noah Pernikoff is back to his life in New York City after becoming the first patient in the world to undergo a complex three-part, robotic-assisted surgery. The robotic arms made it possible for the multidisciplinary team at Penn to successfully remove a rare tumor from Noah's neck, where the skull meets the spine. The ground breaking surgery was completed by a multi-surgeon team, led by Dr. Neil Malhotra, at the Hospital of the University of Pennsylvania in August 2017 over a span of two days and more than 20 hours...More Source: https://www.sciencedaily.com/releases/2018/05/180503142714.htm

Weight loss surgery may cause significant skeletal health problems

The review of published studies notes that weight loss surgery can cause declines in bone mass and strength, and it is linked with an increased risk of bone fractures. Skeletal changes after surgery appear early and continue even after weight loss plateaus and weight stabilizes. Nutritional factors, mechanical unloading, hormonal factors, and changes in body composition and bone marrow fat may contribute to poor bone health...More Source: https://www.sciencedaily.com/releases/2018/05/180502120005.htm
