Cellular Senescence in Cardiovascular and Metabolic Diseases
Posted by Steve Hill in categories: biotech/medical, life extension
Today, we wanted to bring your attention to a new open access paper. The authors here review the role of cellular senescence in the context of the cardiovascular and metabolic diseases of aging. This paper puts special focus on the aging of the vascular system and the role that accumulating numbers of senescent cells play in that process.
What is cellular senescence?
As the body ages, increasing amounts of cells enter a state of senescence. Senescent cells do not divide or support the tissues of which they are a part; instead, they emit a range of potentially harmful signals known collectively as the senescence-associated secretory phenotype (SASP). Senescent cells normally destroy themselves via a programmed process called apoptosis, and they are removed by the immune system; however, as the immune system weakens with age, increasing numbers of these senescent cells escape this process and build up.

Harvard Rewinds the Biological Clock
Posted by Nicholi Avery in categories: biotech/medical, life extension
Harvard reminds the biological clock using NAD+ and NaHS!
Investigators at Harvard Medical School have identified the key cellular mechanisms behind vascular aging and its effects on muscle health, and they have successfully reversed the process in animals.
Could reversing the aging of blood vessels hold the key to restoring youthful vitality? If the old adage “you are as old as your arteries” reigns true then the answer is yes, at least in mice.

New innovations in cell-free biotechnology
Posted by Genevieve Klien in categories: biotech/medical, innovation
A Northwestern University-led team has developed a new way to manufacture proteins outside of a cell that could have important implications in therapeutics and biomaterials.
The advance could make possible decentralized manufacturing and distribution processes for protein therapeutics that might, in the future, promote better access to costly drugs all over the world.
The team set out to improve the quality of manufactured proteins in vitro, or outside a cell, and found success across a number of fronts.

Genetic switch activates transformation of stem cells into heart muscle cells
Posted by Genevieve Klien in categories: biotech/medical, genetics
The discovery of a genetic switch that triggers stem cells to turn into heart cells is a major step in finding treatment for damaged hearts.
Researchers from A*STAR and their colleagues in India have been investigating the molecular and genetic processes by which human embryonic stem cells differentiate into the body’s many types of cells—in particular, cardiomyocytes, or heart muscle cells.
“The effort is underway globally to find ways to differentiate these stem cells into beating functional heart muscle cells so that they can be used for cell-based therapies to treat structural abnormalities,” says Prabha Sampath, from the A*STAR Institute of Medical Biology.

Does your kids’ DNA matter more than which school they go to?
Posted by Genevieve Klien in categories: biotech/medical, education
How well your kids do at school depends in part on the DNA you bequeathed them. What’s not clear is what we should do about this.

Chip detects Legionnaires’ bacteria in minutes, not days
Posted by Genevieve Klien in categories: biotech/medical, computing
When the water in the rooftop cooling towers of a building’s air conditioning system gets infected with Legionella bacteria, people in the building can get potentially-fatal Legionnaires’ disease. Therefore, it’s important to check that water for the bacteria on a regular basis. A new chip is promised to do it faster than ever.
The typical method of checking for Legionella involves putting a water sample in a Petri dish, then waiting 10 to 14 days to see if any bacterial cultures grow. Unfortunately, populations of Legionella can reach outbreak levels is as short a period as one week. Additionally, if an outbreak has already occurred, then its source needs to be ascertained as fast as possible.
That’s why the new LegioTyper chip was created.
