Using DeepMind’s neural network learning system to diagnose eye diseases

14.08.2018 Health Problems

Three institutions working together have applied DeepMind’s neural network learning system to the task of discovering and diagnosing eye diseases. Moorfields Eye Hospital has been working with Google’s DeepMind Health subsidiary and University College London in the effort, and have documented their progress in a paper published in Nature Medicine. As the researchers note, eye doctors currently use a machine […]

A strong immune system helps ward off colds and flus, but it’s not the only factor

10.08.2018 Health Problems

It’s peak flu season. You’re cold, rugged up and squashed on public transport or in the lift at work. You hear a hacking cough, or feel the droplets of a sneeze land on your neck. Will this turn into your third cold this year? No matter how much we try to minimise our exposure to respiratory viruses, it’s far more […]

New stem cell model can be used to test treatments for a rare nervous system disorder

04.08.2018 Health Problems

A City of Hope researcher has developed a stem cell model to assess possible treatments for a rare nervous system disorder that is in the same disease group as Alzheimer’s disease, Parkinson’s disease and amyotrophic lateral sclerosis (ALS). The finding takes Yanhong Shi, Ph.D., senior author of the study, and her colleagues one step closer to finding a way to […]

Researchers solve mystery of how ALL enters the central nervous system

20.07.2018 Health Problems

A deadly feature of acute lymphoblastic leukemia (ALL) is its invasion of the central nervous system. ALL in the central nervous system is very difficult to treat, because most drugs are blocked from the organ system due to a “blood-brain barrier” designed to protect the brain. How cancer cells enter the central nervous system has been an unanswered question for […]

Biomaterial particles educate immune system to accept transplanted islets

05.06.2018 Health Problems

By instructing key immune system cells to accept transplanted insulin-producing islets, researchers have opened a potentially new pathway for treating type 1 diabetes. If the approach is ultimately successful in humans, it could allow type 1 diabetes to be treated without the long-term complications of immune system suppression. The technique, reported June 4 in the journal Nature Materials, uses synthetic […]

Researchers discover how colon cancer mutates to escape the immune system

05.06.2018 Health Problems

A UCLA-led study has found how colon cancer alters its genes during development in order to avoid detection by the immune system, creating a specific genetic imprint in the process. This ability of cancer to change its genes—a process called immunoediting—had never been described in colon cancer before, and the new understanding could help researchers develop new immunotherapies that target […]

A system of check and balances in the blood

25.05.2018 Health Problems

Hematopoietic stem cells (HSCs) give rise to blood and immune cells, and are therefore essential for survival. The group of Manuela Baccarini at the Max F. Perutz Laboratories, a joint venture of the University of Vienna and the Medical University of Vienna, has now shown how intracellular signaling can safeguard this delicate balance between activation and dormancy. Their results are […]

Deep space radiation treatment reboots brain’s immune system

22.05.2018 Health Problems

Planning a trip to Mars? You’ll want to remember your anti-radiation pills. NASA and private space companies like SpaceX plan to send humans to the red planet within the next 15 years—but among the major challenges facing future crewed space missions is how to protect astronauts from the dangerous cosmic radiation of deep space. Now the lab of UCSF neuroscientist […]

Automated system better identifies patients at risk for ventilator-associated pneumonia

18.05.2018 Health Problems

An automated system for identifying patients at risk for complications associated with the use of mechanical ventilators provided significantly more accurate results than did traditional surveillance methods, which rely on manual recording and interpretation of individual patient data. In their paper published in Infection Control & Hospital Epidemiology, a Massachusetts General Hospital (MGH) research team report that their system—using an […]

Dual-hormone system may lower time in hypoglycemia in T1DM

16.05.2018 Health Problems

(HealthDay)—For physically active adults with type 1 diabetes, the addition of glucagon delivery to a closed-loop system using wearable sensors with automated exercise detection is associated with reduced hypoglycemia, according to a study published online May 11 in Diabetes Care. Jessica R. Castle, M.D., from the Oregon Health & Science University in Portland, and colleagues enrolled 20 participants with type […]
