In searching for treatments for Covid-19, researchers discovered that a cancer drug called Aplidin (aka: Plitidepsin), originally isolated from Mediterranean sea squirts, was up to 27.5 times more effective at killing the virus in cell cultures than the FDA-approved drug Remdesivir! Importantly, it was also shown to be effective at preventing the virus from replicating in mice. Sources: Youtube KM White, R Rosales, S Yildiz, T Kehrer, L Miorin, E […]
Researchers at the University of Saskatchewan in Canada compared how pigs and fish absorb glucose (i.e. sugar) from the diet. They did this by measuring how well glucose moves across the intestinal wall. Their findings appear in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology. Transport of dietary glucose from the gut to the blood is facilitated by glucose transporters that pick up glucose and move it […]
The Iowa Physiological Society held their 23rd annual meeting today. It was a huge success! Seminars were on a diverse array of topics including epilepsy, chronic pain, Parkinson’s disease, hypertension caused by menopause, how heat exposure impacts insulin’s actions in skeletal muscle tissue, how exercise changes blood flow in muscles of individuals with obesity, factors that change the ability to grow new blood vessels, The Keynote Speaker was Dr. Mark […]
Bats and dolphins are famous for using echolocation to help navigate their surroundings. In contrast, humans normally rely on vision to navigate. When vision is impaired, however, we can learn to rely on echolocation. Although it is rare to find people who rely solely on hearing:
A new study shows that walking your dog is good for your health. Here is a YouTube video summarizing the findings of the study: Let’s not forget that walking your dog is also very good for your dog. According to PetMD, some benefits include weight control, keeping your dog limber, controlling destructive behaviors and hyperactivity, and of course building a bond between you and your pet. If you have a […]
A recent study published in Microbiome from researchers at the University of Alberta shows that babies from families with pets had nearly two-fold increases in the amount of two specific microbes in their guts, Ruminococcus and Oscillospira. These particular microbes are associated with reduced risks of developing childhood allergies as well as obesity. According to study author Dr. Anita Kozyrskyj, “There’s definitely a critical window of time when gut immunity and microbes […]
Who would have thought tiny fish could lead to big advances in medicine? Zebrafish (Danio rerio) and mammals have similar anatomy and physiology of the brain, eyes, gut, and cardiovascular systems. Some of the reasons why these fish are good models to understand cardiovascular physiology were recently explored in a new article published in Physiological Reviews. Animal models are used in research that seeks to understand both normal physiological mechanisms as well […]
The opening session was great! Eric Hoffman (Children’s National Medical Center) presented work on chronic inflammatory diseases in children. He mentioned that while diets high in fats and carbohydrates (i.e. Western diets), obesity and sedentary lifestyles are associated with inflammation and related diseases (ex: asthma, type 2 diabetes), another contributor could be hormones. Kids who stay indoors more often have reduced exposure to sunlight and exercise less. This may alter the normal biological clock of […]
