Warren symposium follows legacy of geneticist giant

If we want to understand how the brain creates memories, and how genetic disorders distort the brain’s machinery, then the fragile X gene is an ideal place to start. That’s why the Stephen T. Warren Memorial Symposium, taking place November 28-29 at Emory, will be a significant event for those interested in neuroscience and genetics. Stephen T. Warren, 1953-2021 Warren, the founding chair of Emory’s Department of Human Genetics, led an international team that discovered Read more

Tracing the start of COVID-19 in GA

At a time when COVID-19 appears to be receding in much of Georgia, it’s worth revisiting the start of the pandemic in early 2020. Emory virologist Anne Piantadosi and colleagues have a paper in Viral Evolution on the earliest SARS-CoV-2 genetic sequences detected in Georgia. Analyzing relationships between those virus sequences and samples from other states and countries can give us an idea about where the first COVID-19 infections in Georgia came from. We can draw Read more

Football metabolomics

Following on the recent announcement of the Atlanta Hawks training center, here’s a Nov. 2015 research paper from Emory’s sports cardiologist Jonathan Kim, published in Annals of Sports Medicine and Research.

Jonathan Kim, MD

Kim and colleagues from Emory Clinical Cardiovascular Research Institute studied blood samples from 15 freshman football players at Georgia Tech before and after their first competitive season. The researchers had the help of metabolomics expert Dean Jones. Kim has also previously studied blood pressure risk factors in college football players.

On average, football players’ resting heart rate went down significantly (72 to 61 beats per minute), but there were no significant changes in body mass index or blood pressure. The research team observed changes in players’ amino acid metabolism, which they attribute to muscle buildup.

This finding may seem obvious, but imagine what a larger, more detailed analysis could do: start to replace locker room myths and marketing aimed at bodybuilders with science. This was a small, preliminary study, and the authors note they were not able to assess diet or nutritional supplementation. Read more

New 3D MRI Technology Puts Young Athletes Back in Action

Emory MedicalHorizon
New technology has made it possible for surgeons to reconstruct ACL tears in young athletes without disturbing the growth plate.

John Xerogeanes, MD, chief of the Emory Sports Medicine Center and colleagues in the laboratory of Allen R. Tannenbaum, PhD, professor in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University, have developed 3-D MRI technology that allows surgeons to pre-operatively plan and perform anatomic Anterior Cruciate Ligament (ACL) surgery.

The ACL is one of the four major ligaments in the knee, somewhat like a rubber band, attached at two points to keep the knee stable. In order to replace a damaged ligament, surgeons create a tunnel in the upper and lower knee bones (femur and tibia), slide the new ACL between those two tunnels and attach it both ends.

Traditional treatment for ACL injuries in children has been a combination of rehabilitation, wearing a brace and staying out of athletics until the child stops growing – usually in the mid-teens – and ACL reconstruction surgery can safely be performed.  Surgery has not been an option with children for fear of damage to the growth plate that would cause serious problems later on. If you want to bet on athletes that have recently recovered from their injuries, you can check out safe platforms such as 겜블시티 가입코드.

Xerogeanes explains that prior to using the 3-D MRI technology, ACL operations were conducted with extensive use of X-Rays in the operating room, and left too much to chance when working around growth plates.

Preparation with the new 3-D MRI technology allows surgery to be completed in less time than the traditional surgery using X-Rays, and with complete confidence that the growth plates in young athletes will not be damaged. Such athletes may include from various sports like basketball, football, archery and etc.
