Aging and Stem Cells | Theodore Ho | TEDxMiddlebury

Dr. Theodore Ho talks about the rapidly expanding possibilities of stem cells to be used in reversing or slowing the aging process. He discusses his previous and current work with the brain, including such methods as tissue clearing, multifiber photometry and optogenetics, and single resolution calcium imaging and control. Dr. Ho is a neuroscientist and stem cell biologist studying the mechanisms and causes of biological aging and potential strategies to slow or reverse them, in order to prevent the onset of age

Associated diseases to help us live healthier and longer lives.

He completed a four-year joint bachelor’s/master’s degree program in.

Human developmental and regenerative biology/bioengineering at.

Harvard University, and he received his PhD in Biophysics from the.

University of California San Francisco, studying stem cell aging in the lab of Dr. Emmanuelle Passegue. In college he developed a nanoparticle drug delivery system, in graduate school he discovered previously unknown mechanisms of cellular and molecular aging of stem cells, and now in the Deisseroth lab he is using optical recording and perturbation of neuronal activity to study neural circuit dynamics that control behavior. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

7000 Year Old DNA Found in Artsakh Cave Matches Genes of Modern Armenians

AZOKH, Nagorno-Karabakh (People of Ar)—Scholars from Britain, US, Denmark and Armenia led by Professor Levon Yepiskoposyan have been examining prehistoric caves near the village of Azokh in Artsakh (Nagorno Karabakh) and found unique artifacts from different periods, among them a tooth from a human who lived 7000 years ago. Due to the cave’s climate DNA was preserved inside the tooth and was send to Copenhagen University’s genetics department (in Denmark) for examination. The results of this inquiry have revealed that the genetic makeup of the tooth belonging to an individual 7000 years ago perfectly matches with the genetic makeup of modern Armenians.

“This is the conclusion we’ve reached after numerous excavations carried out on the territory of Karabakh, where we examined more than a dozen caves, among them the cave of Azokh and Alexan Uzes,” Yepiskoposyan said.

Diabetes Drugs Being Tested For Anti-Aging Benefits

Acarbose and Metformin are commonly used to treat type 2 diabetes, but now they are also being tested for anti-aging effects, and according to the researchers these two FDA approved drugs have big promise.

In mice testing Acarbose and Metformin were demonstrated to increase health, lifespan, and longevity of the animals. These two drugs are now being tested in monkeys that have a similar physiology, reproductive system, and aging pattern as humans, in research being conducted at Texas Biomedical Research Institute which is supported by a pilot grant provided by the San Antonio Claude D. Pepper Older Americans Independence Center.

“I think this type of research can change what life is like for geriatric people,” said Corinna Ross, Ph.D, Associate Professor, Southwest National Primate Research Center at Texas BioMed.

Skin and Mouth Biomarkers More Predictive Than Gut

Lifespan.io

 A new study published in mSystems, a journal from the American Society for Microbiology, shows that the skin and mouth microbiomes are better predictors of age than the gut microbiome.

A very broad study

The authors used a very large population that is highly impressive among studies of this kind. Previously, a team containing some of the same researchers had done a gut microbiome study of over four thousand people from multiple countries [1]. This time, the researchers took skin, saliva, and fecal samples from roughly 2,000, 2,500, and 4,500 people, respectively; this study was done with nearly 9,000 people in total, and the team stated that it was the most comprehensive microbiome study done to date. The team used a “random forest” machine learning approach to determine what microbiota were and were not predictive of age [2].

Going mobile: FDA clears world’s first bedside MRI scanner-on-wheels

The FDA has cleared the world’s first portable MRI system, designed to be wheeled to a hospital bedside for scanning a patient’s head and brain.

Developed by Hyperfine Research for people age two and older, the point-of-care imaging system weighs about one-tenth that of a conventional, fixed MRI system. About three feet wide and five feet tall, the device fits in an elevator and runs off an everyday power outlet to create both clinical contrast images and 3D renders.

“More than 40 years after its first use, MRI remains a marvel. Unfortunately, it also remains inaccessible,” Hyperfine Chief Medical Officer Khan Siddiqui said in a statement. “It’s time that MRI made the jump to point of need just like X-ray and ultrasound have before it.”
