Endothelial DNA Methylation Goes With the Flow

by Eliza B. in EpiBeat

Atherosclerosis is an inflammatory disease of the arterial walls, and is the major cause of heart attack and stroke. Atherosclerosis is localized to curves and branches in the vasculature where disturbed blood flow (d-flow) is able to alter gene expression and induce endothelial cell (EC) dysfunction. Our lab’s work focuses on the mechanism by which ...

Yaks Use Highest, Steepest Parts of the World for No-Boys-Allowed Meetings

by Elizabeth Preston in Inkfish

It’s hard for humans to tell what wild yaks are doing up there. Living high in the Tibetan Plateau, the rare ungulates are not easy to find. When scientists managed to track some down, they saw that females are hanging out in huge groups with no males allowed. And, though no one knows why, the […]The post Yaks Use Highest, Steepest Parts of the World for No-Boys-Allowed Meetings appeared first on Inkfish.... Read more »

Vitamin D and autism: same old story?

by Paul Whiteley in Questioning Answers

I have to say that I wasn't all that surprised when I read the conclusions to the study by Eva Kočovská and colleagues [1] (open-access here) talking about significantly lower levels of 25-Hydroxyvitamin D3 (25(OH)D3) levels detected in their small cohort of young adults diagnosed with an autism spectrum disorder (ASD) compared with various control populations.A deficiency or insufficiency of vitamin D - the sunshine vitamin/hormone - in relation to quite a few cases of autism is somethin........

Addiction, anhedonia, and reward processing in smokers

by neurosci in Neuroscientifically Challenged










In those who are addicted to drugs (or any other substance or behavior), the desire to re-experience the intoxicating effects they initially felt when they used the drug can be overwhelming. It can lead to compulsive drug-seeking, obsessive thinking, and irrational behavior. In addition to these new thought patterns and behaviors, however, addiction is also is associated with a diminished ability to experience pleasure from non-drug rewards. This reduced pleasure is termed........ Read more »

by Erin Campbell in HighMag Blog

As the widespread therapeutic use of stem cells moves closer to reality, I just fasten my seatbelt a little tighter. An exciting time for stem cells and their scientist stalkers, a recent paper shows the regeneration of damaged monkey hearts by human embryonic stem cell-derived cardiomyocytes.  Human embryonic stem cells (hESCs) can be programmed to differentiate into countless different cell types. hESCs are already being tested in humans to treat retinal diseases and spinal cord inju........

Why do we get pleasure from sad music?

by Janet Kwasniak in Neuro-patch

  Sadness is a negative emotion; and, we recognize sadness in some music; but yet, we often enjoy listening to sad music. We can be positive about a negative emotion. A recent paper by Kawakami (citation below) differentiates between some hypotheses to explain this contradiction. The hypotheses that the response has to do with musical […]... Read more »

More suramin and autism [mouse] findings

by Paul Whiteley in Questioning Answers

The headline: 'Century-old drug reverses signs of autism in mice' brought the paper by Jane Naviaux and colleagues [1] (open-access) to my attention and some slightly familiar work (see here) on the use of suramin in a mouse model of autism, or rather a mouse model of maternal immune activation. Indeed, I seem to remember that the previous study by this group [2] courted similar publicity, with some familiar headlines...Not lecturing... @ Wikipedia The latest offering from Naviaux et a........
