Ohio is talking about fixing broken hearts, the physiology of freezing, combating opioid addiction and more

The Ohio Physiological Society held their 33rd Annual Meeting at the University of Cincinnati this weekend. The keynote address was given by Dr. Mark Sussman from San Diego State University. He spoke about current research strategies that aim to improve the ability for the heart to repair itself after heart failure. Dr. Perwez Alam (University of Cincinnati) also spoke about using siRNA to try to repair heart tissue after heart attacks and […]

Chocolate: Bad for Fido, good for us?

Many animals, especially dogs and cats, cannot tolerate theobromine which is an alkaloid from the cacao plant. Studies of humans, however, have found many beneficial health effects of theobromine, caffeine as well as flavonoids found in cocoa (Martinez-Pinilla et al., 2015). A new study published in Journal of Applied Physiology examined whether cocoa extract can improve heart health in individuals exercising in hypoxic conditions. Hypoxia (i.e. low atmospheric oxygen) reduces the […]

Monogamy is good for the heart

In honor of Valentine’s Day, let’s talk about prairie voles (Microtus ochrogaster). These animals are often used to study pair bonding because they are one of only a handful of mammalian species that form lifelong socially monogamous pair bonds after mating and cohabitating for at least 6 hours. According to a study published several years ago in Nature Neuroscience, this pair bonding behavior is regulated by specific genes in their […]

Avian vascular anatomy revealed

This is such a beautiful award-winning image of the complex vascular networks in a pigeon. The image was captured using  CT scan technology and a novel contrasting agent called BriteVu that allows visualization of even tiny capillaries. This image was captured by Scott Echols who is a member of the Grey Parrot Anatomy Project, whose goals are to create technologies to study animal anatomy. The complex capillary network located in […]
