Bacillus probiotics health benefits have been until now quite poorly studied in the elderly population. This study aimed to assess the effects of Bacillus subtilis CU1 consumption on immune stimulation and resistance to common infectious disease (CID) episodes in healthy free-living seniors.

One hundred subjects aged 60–74 were included in this randomized, double-blind, placebo-controlled, parallel-arms study. Subjects consumed either the placebo or the probiotic (2.10B. subtilis CU1 spores daily) by short periodical courses of 10 days intermittently, alternating 18-day course of break. This scheme was repeated 4 times during the study. Symptoms of gastrointestinal and upper/lower respiratory tract infections were recorded daily by the subjects throughout the study (4 months). Blood, saliva and stool samples were collected in a predefined subset of the first forty-four subjects enrolled in the study. B. subtilis CU1 supplementation did not statistically significantly decrease the mean number of days of reported CID symptoms over the 4-month of study (probiotic group: 5.1 (7.0) d, placebo group: 6.6 (7.3) d, P = 0.2015). However, in the subset of forty-four randomized subjects providing biological samples, we showed that consumption of B.

To reduce the damage to his brain and organs, Brooks was rushed to the University of Pennsylvania, where Dr. Lance Becker and his team cooled the young man’s core temperature to below 90 degrees Fahrenheit—a process called “induced hypothermia.” This is often done to cardiac arrest patients, either by injecting them with a cold saline solution or placing ice packs on them to increase their chances of complete recovery.

The dose of cold saved his life. Brooks had no brain damage, a remarkable feat that has led doctors to explore more ways to use induced hypothermia in emergency settings.

Now Dr. Sam Tisherman and his team at the University of Maryland, in collaboration with the University of Pittsburgh, plan to put 10 patients into a more severe form of hypothermia than what Brooks got, something known as “suspended animation.” They’ll flush their bodies with a cold fluid, cooling (and therefore preserving) tissue. The experimental trial, known as emergency preservation and resuscitation for cardiac arrest from trauma ( EPR-CAT), is funded by the U.S. Department of Defense, and it is the first time doctors are harnessing profound hypothermia (pushing body temperatures to as low as 50 degrees) to save lives.

Chinese scientists used an adapted version of a controversial gene-editing technique to correct a disease-causing mutation in human embryos, a medical first cautiously hailed by other experts Thursday.

The team used a so-called “base editor”—an adaptation of the CRISPR-Cas9 DNA snipping tool—to correct a single, mutated “letter” among about three billion in the intricate coding of the human genome.

The targeted mutation can cause humans to be born with beta-Thalassaemia, a potentially fatal .

A robot in China has successfully performed dental surgery on a volunteer. The recent procedure records the first successful autonomous implant surgery, and could change the way dental surgery is performed in China.

Brave Volunteer, Successful Surgery

Would you willingly get dental surgery from a robot? One woman did and because of her bravery, experts saw how the robot was able to perform dental surgery successfully and efficiently — not to mention she got two of her teeth replaced with dental implants.

Researchers at the University of Florida have developed a new gene therapy that shows promise in fighting multiple sclerosis (MS). Testing the technique in mice, the team found that the treatment was effective in preventing animals from developing the mouse equivalent of the disease, and almost completely reversed the symptoms in those that were already suffering from it.

MS is a debilitating immunological disease where the body’s immune system mistakenly attacks myelin, the tissue that surrounds and protects nerves. Once damaged, the exposed nerves can effectively short-circuit, resulting in issues with muscles, vision, speech and motor control. Potential treatments being studied include training the body to better tolerate myelin, drugs that target the immune system’s B cells, blocking proteins that cause inflammation in the body, or even “rebooting” the entire immune system.

The state of Illinois is testing a new way for people to prove their identities, albeit without the need to request their birth certificates and wait weeks for it to arrive in the mail. The state aims to give citizens more control of their data, as well as provide solace in knowing it’s more secure than ever.

To accomplish this task, the state is turning to the same blockchain technology that companies like Bitcoin and Ethereum utilize for their own networks. In August, the Illinois Blockchain Initiative — a collaboration launched by the state to explore blockchain and distributed ledger technology — announced it’s partnering with self-sovereign identity solutions firm Evernym to create an online ledger that’s only accessible to the owner of the ID and any other individuals they’re granted access. It’s very similar to how the technology could be used to track and share information between hospitals.

A team of researchers from Sun Yat-sen University have used gene editing to correct a potentially fatal blood condition. This world-first accomplishment represents the first step to a future where we literally edit disease out of our bodies.

Beta-thalassemia is a blood disorder that plagues individuals throughout the entirety of their lives. There is no truly viable cure. The only real hope that people have of overcoming this disease is either a stem cell or bone marrow transplant; however, these procedures are rarely performed due to the life-threatening risk that comes with them.
