Ebola confirmed in a city of more than 1 million in Congo
Posted by Quinn Sena in categories: biotech/medical, health
JOHANNESBURG (AP) — The global health community gulped Thursday with the announcement that a case of Ebola had been confirmed in a city of more than 1 million in Congo, bringing the latest outbreak of the often deadly hemorrhagic fever out of remote rural areas. “Confirmation of urban #Ebola in #DRC is a game changer in this outbreak – the challenge just got much much tougher,” the World Health Organization’s emergencies chief, Dr. Peter Salama, said on Twitter. Here’s a look at the outbreak.
What is Ebola?
Ebola is a virus that without preventive measures can spread quickly between people and is fatal in up to 90 percent of cases. The symptoms include fever, vomiting, diarrhea, muscle pain and at times internal and external bleeding. Symptoms can start to occur between two and 21 days from infection, according to WHO.

Effect of low-level laser therapy on mesenchymal stem cell proliferation: a systematic review
Posted by Quinn Sena in category: biotech/medical
Low-level laser therapy (LLLT) has been used in several in vitro experiments in order to stimulate cell proliferation. Cells such as fibroblasts, keratinocytes, lymphocytes, and osteoblasts have shown increased proliferation when submitted to laser irradiation, although little is known about the effects of LLLT on stem cells. This study aims to assess, through a systematic literature review, the effects of LLLT on the in vitro proliferation of mesenchymal stem cells. Using six different terms, we conducted an electronic search in PubMed/Medline database for articles published in the last twelve years. From 463 references obtained, only 19 papers met the search criteria and were included in this review. The analysis of the papers showed a concentration of experiments using LLLT on stem cells derived from bone marrow, dental pulp, periodontal ligament, and adipose tissue. Several protocols were used to irradiate the cells, with variations on wavelength, power density, radiation time, and state of light polarization. Most studies demonstrated an increase in the proliferation rate of the irradiated cells. It can be concluded that the laser therapy positively influences the in vitro proliferation of stem cells studied, being necessary to carry out further experiments on other cell types and to uniform the methodological designs.

New single vaccination approach to killer diseases
Posted by Quinn Sena in category: biotech/medical
Scientists from the University of Adelaide’s Research Centre for Infectious Diseases have developed a single vaccination approach to simultaneously combat influenza and pneumococcal infections, the world’s most deadly respiratory diseases.
The researchers say a single vaccination—combining vaccines from the new class of vaccines they are developing—will overcome the limitations of current influenza and pneumococcal vaccines used around the world.
Published today in the prestigious journal Nature Microbiology, they have shown that the new Influenza A virus vaccine under development (based on inactivated whole influenza virus) induces enhanced cross-protective immunity to different influenza strains, when it is co-administrated with the new class of pneumococcal vaccine.

Rejuvenate Bio Using Gene Therapy Has Reversed Aging Effects in Mice and Dogs
Posted by Mark Sackler in categories: biotech/medical, genetics, life extension
Is it me? Or am I the only one who wishes George Church was not so secretive? https://www.nextbigfuture.com/2019/05/rejuvenate-bio-using-g…dogs.html?
Harvard Genetics Giant Geroge Church and Noah Davidsohn, a former postdoc in his lab, have engaged in a secretive antiaging venture called Rejuvenate Bio. They are making old dogs new. They have conducted gene therapy on beagles and are currently advertising for Cavalier King Charles spaniels to use gene therapy to fix their hearts.
They have identified many other targets for gene-based interventions, studying a database of aging-related genes.

Scientists discover self-defense “switch” for stem cells
Posted by Quinn Sena in categories: biotech/medical, futurism
With the power to turn themselves into any other cell in the body, stem cells have a future as a key treatment for a range of diseases and injuries. The problem is, they lack some of the self-defense mechanisms that other cells have, leaving them open to attack from viruses and other threats. Now, researchers from the University of Edinburgh may have found a way to switch this mechanism back on, making stem cell treatments more effective.
