    A Miniature Robot that could check Colons for Early Signs of Disease

    June 20, 2019, Categories  Physics, Technology/Electronics, Health/Medical

    Engineers have shown it is technically possible to guide a tiny robotic capsule inside the colon to take micro-ultrasound images. Known as a Sonopill, the device could one day replace the need for patients to undergo an endoscopic examination, where a semi-rigid scope is passed into the bowel – an invasive procedure that can be painful.
    The Sonopill is a small capsule – with a diameter of 21mm and length of 39mm, which the engineers say can be scaled down. The capsule houses a micro ultrasound transducer, an LED light, camera and magnet.

    Micro-ultrasound images also have the advantage of being better able to identify some types of cell change associated with cancer...

    A new cooling vest for sports athletes may ensure everyone can compete safely in sweltering summer conditions such as the upcoming 2020 Summer Olympics. Strategies to cope with body heat in sports is a pressing issue. The Tokyo Olympics will be held in the hot and muggy Japanese summer where the ambient temperature is expected to be above 33°C. Athletes have to worry about performing under pressure of the high-stakes competition but also now have to deal with a very hot and humid climate...

    Topical Cream shows promise in Treatment of Skin Pigmentation disease, Vitiligo

    Hands with vitiligo
    “Topical ruxolitinib has the potential to change the way vitiligo is treated. Not only is it effective at repigmenting the skin, but it has an excellent safety profile,” said Dr. Rosmarin.

    A nationwide phase II clinical trial, coordinated out of Tufts Medical Center in Boston, has found that a topical cream was extremely effective in reversing the effects of vitiligo, a relatively common autoimmune disease that causes loss of skin pigmentation. Topical application of the medicated cream, ruxolitinib, which is currently used as an oral treatment for certain blood disorders, resulted in substantial improvement of facial vitiligo symptoms in nearly half of the trial’s participants...

    Increasing Red Meat intake linked with Heightened risk of early Death

    Image result for Increasing red meat intake linked with heightened risk of early death
    Association of changes in red meat consumption with total and cause specific mortality among US women and men: two prospective cohort studies. BMJ, 2019; l2110 DOI: 10.1136/bmj.l2110

    Swapping red meat for healthier animal or plant-based alternatives such as eggs and fish, whole grains and vegetables may lower risk. Processed red meat in particular is associated with a heightened risk of death, suggests a large US study published in The BMJ today.

    High intake of red meat, such as beef, pork and lamb, has been previously linked with a higher risk of type 2 diabetes, cardiovascular disease, certain types of cancers, and premature death. But little is known about how changes in red meat intake may influence risk of death.

    So to explore this further, a team of researchers based in t...
