Ian’s fitness journey using Holywell Fitness Centre

Ian’s fitness journey using Holywell Fitness Centre

I used to be very active in my younger years, played a lot of sport and really enjoyed it. But unfortunately over the last 15 years I really haven’t undertaken any physical activity at all, which has led to the inevitable consequences and I felt it was time to do something about that. As I saw it there were two choices. I could undertake activity on my own, and that…

Will We Ever Cure Breast Cancer?

Will We Ever Cure Breast Cancer?

Breast cancer is the second most common cancer diagnosed in women in the United States, right behind skin cancer. While it largely affects women, it can also occur in men. Fortunately, thanks to awareness, early detection, and research, survival rates have increased but there’s still a lot we’re learning. So how far have we come in understanding this disease? Breast cancer affects the cells in the tissue of the breast….

G-Protein Coupled Hormone Signal Transduction

G-Protein Coupled Hormone Signal Transduction

This animation depicts the surface view of a target cell and its interaction with a peptide hormone as a model to demonstrate g-protein coupled signal transduction in cells. Peptide hormones generally consist of short chains of amino acids. Because peptide hormones are often quite short, they lack a rigid three-dimensional conformation and are flexible. Peptide hormones are usually water-soluble and too large to pass through the lipid plasma membrane of…

The Upside of Stress

The Upside of Stress

When I need to unwind, there’s nothing I love more than an “experience.” Snorkeling in the Great Barrier Reef, Zip-lining or even just riding roller coasters at Coney Island. These aren’t relaxing activities by any stretch. In fact, they get my adrenaline pumping, so physiologically I’m experiencing “stress,” but I still enjoy them, and I still feel better after them. Stress usually gets a bad rap – some studies have…

In a dark corner of the basement of Beyer Hall there’s a gym strictly dedicated for members of the Iowa State Weight Club. This is a gym for serious power lifters and strongman competitors and one of its most dedicated members is Amy Kurr. “Powerlifting’s great it helps you learn to stand up when you fall down. Kurr is one of the most experienced members of the ISU Weight Club….

Tertiary structure of proteins | Macromolecules | Biology | Khan Academy

– [Voiceover] In the vidoe on protein structure, we talked about the different orders of structure, starting with primary structure, and this is all a bit of a review right now. Primary structure is just a sequence of the amino acids. But then from there we can start thinking about how does it get shaped by thinking about the secondary structure. And secondary structure is all about interactions of the…

Fighting Obesity with Local Solutions

Fighting Obesity with Local Solutions

[MUSIC PLAYING] In 2010, in our community, which is central Ohio, 1/3 of children are overweight or obese. Now that’s worrisome, because we know that a number of the children who are overweight will become overweight adults further down the road. Also, obesity is linked to a number of serious comorbid conditions, like hypertension, high cholesterol, obstructive sleep apnea, Type 2 diabetes. And these are really serious conditions, particularly in…
