Terminal assessment of the muscles of the triceps surae, including soleus **(A)**and gastrocnemius wet mass **(D)**, soleus **(B)** and gastrocnemius **(E)** average cross sectional area (CSA), and representative images of the soleus **(C)** and gastrocnemius **(F)** muscles stained with anti-collagen VI (red), anti-slow-skeletal myosin heavy chain (green), and DAPI (blue). N = 6 per group. The results are presented as mean ± SEM; the results of the *post hoc* tests following the ANOVA are indicated. ^*p < 0.05, ^∗∗p < 0.01, and ^∗∗∗p < 0.001 vs. PWB100, respectively. ^#p < 0.05, ^###p < 0.001, and ^{#⁢#⁢#⁢#}p < 0.0001 vs. PWB100 + RSV, respectively. ^$p < 0.05, ^$$p < 0.01, and ^$$$p < 0.001 vs. PWB40, respectively.

New Cell discovered that can Heal Hearts

July 18, 2019, Health/Medical, Biology/Biotechnology

These are photos of the hearts from two mice, one month after a heart event.

Fundamental scientific discovery could lead to new ways to repair damaged hearts. University of Calgary researchers are the first to discover a previously unidentified cell population in the pericardial fluid found inside the sac around the heart. The discovery could lead to new treatments for patients with injured hearts. The study led by Drs. Paul Kubes, PhD, Justin Deniset, PhD and Paul Fedak, MD, PhD is published in the journal Immunity.

The Kubes lab, in collaboration with the Fedak lab, found that a specific cell, a Gata6+ pericardial cavity macrophage, helps heal an injured heart in mice. The cell was discovered in the pericardial fluid (sac around the heart) of a mouse with heart injury...

Physics research groups have generated free electrons from organic semiconductors when combined with a single atomic layer of molybdenum disulfide, a recently discovered 2D semiconductor.

Imagine printing electronic devices using a simple inkjet printer – or even painting a solar panel onto the wall of a building. Such technology would slash the cost of manufacturing electronic devices and enable new ways to integrate them into our everyday lives. Over the last two decades, a type of material called organic semiconductors, made out of molecules or polymers, has been developed for such purposes...
