‘Alexa, Titrate My Insulin’: AI App Boosts Glycemic Control in Randomized Trial

Posted by in categories: biotech/medical, information science, robotics/AI

Beyond glycemic benefits, users of the app also reported significantly less-related emotional distress than standard care (−1.9 vs 1.7 points in composite survey scores, P =0.03).

“We are currently working on making technology like this accessible to patients outside of research settings because we think it can really help patients in underserved areas who need high-touch care to get their under control,” Nayak said.

The researchers developed their custom voice-based AI app and had it powered by Alexa (Amazon wasn’t involved with the study). The software was equipped with titration algorithms by the American Association of Clinical Endocrinologists and the American College of Endocrinology and included emergency protocols to handle hypoglycemia and hyperglycemia.

Scientists Uncover Unexpected Behavior in Active Particles

Posted by in categories: biotech/medical, computing

The field of research focusing on self-propelled particles, known as active particles, is rapidly expanding. In most theoretical models, these particles are assumed to maintain a constant swimming speed. However, this assumption does not hold true for many experimentally produced particles, like those propelled by ultrasound for medical applications. Their propulsion speed varies with orientation.

A team of physicists, led by Prof. Raphael Wittkowski from the University of Münster and including Prof. Michael Cates from the University of Cambridge, conducted a collaborative study to explore how this orientation-dependent speed influences the behavior of particle systems, particularly in cluster formation.

They combined computer simulations with theoretical analysis to uncover new effects in systems of active particles with orientation-dependent speeds. Their findings were recently published in the journal Physical Review Letters.

Improving Therapeutic Vaccination against Hepatitis B—Insights from Preclinical Models of Immune Therapy against Persistent Hepatitis B Virus Infection

Posted by in category: biotech/medical

Chronic hepatitis B affects more than 250 million individuals worldwide, putting them at risk of developing liver cirrhosis and liver cancer. While antiviral immune responses are key to eliminating hepatitis B virus (HBV) infections, insufficient antiviral immunity characterized by failure to eliminate HBV-infected hepatocytes is associated with chronic hepatitis B. Prophylactic vaccination against hepatitis B successfully established protective immunity against infection with the hepatitis B virus and has been instrumental in controlling hepatitis B. However, prophylactic vaccination schemes have not been successful in mounting protective immunity to eliminate HBV infections in patients with chronic hepatitis B.

Scientists learn from creepy skin parasites how to suppress pain

Posted by in category: biotech/medical

Painless lesions investigated in mice

Now, for the first time, researchers have looked into the lesions on mouse skin to assess if there are any metabolic signalling pathways that are responsible for thwarting pain. The aim is to hopefully use this mechanism to help people suffering from debilitating pain through the development of non-narcotic pain medications.

“No one knows why these lesions are painless – but it has been thought that the parasite somehow manipulates the host physiological system,” said Abhay Satoskar, senior author of the study and professor of pathology in The Ohio State University College of Medicine.

Pathogens use force to bypass the immune system, new research says

Posted by in category: biotech/medical

Researchers have found that some pathogens can use physical force to enter and survive inside cells, bypassing the immune system. This could lead to new ways of fighting intracellular infections.

Bottlenose dolphins can sense electric fields, study shows

Posted by in categories: biotech/medical, neuroscience

A small team of bio-scientists from the University of Rostock’s Institute for Biosciences and Nuremberg Zoo’s Behavioral Ecology and Conservation Lab, both in Germany, has found evidence that bottlenose dolphins can sense electric fields. In their study, reported in the Journal of Experimental Biology, the group tested the ability of two captive bottlenose dolphins to sense a small electric field.

Many creatures in the are able to sense an electric field—some sharks and the platypus, for example—but only one type of marine mammal has been found to have the ability: the Guiana dolphin. In this new effort, the research team wondered if other types of dolphins have the ability.

They chose to study for two reasons: a pair of were available for testing at the nearby Nuremberg Zoo, and prior research suggested that neural cells in the vibrissal crypts situated along the dolphins’ snouts strongly resembled the electric-field detectors observed in sharks.

Certain Skin Bacteria can Inhibit Growth of Antibiotic-Resistant Bacteria

Posted by in category: biotech/medical

Researchers have found a bacteriocin that can help inhibit the growth of antibiotic-resistant bacteria. Infections with antibiotic-resistant bacteria are a growing global problem. Part of the solution may lie in copying the bacteria’s own weapons. The research environment in Tromsø has found a new bacteriocin, in a very common skin bacterium. Bacteriocin inhibits the growth of antibiotic-resistant bacteria that are often the cause of disease and can be difficult to treat.

One million deaths each year.

The fact that we have medicines against bacterial infections is something many people take for granted.
