Accounting for historical demographic features, such as the strength and timing of gene flow and divergence times between closely related lineages, is vital for many inferences in evolutionary biology. Approximate Bayesian Computation (ABC) is one method commonly used to estimate demographic parameters. However, the DNA sequences used as input for...

The transcatheter aortic valve replacement (TAVR) procedure has emerged as a minimally invasive treatment for patients with aortic valve stenosis (AVS). However, alterations in serum factor composition and biological activity after TAVR remain unknown. Here, we quantified the systemic inflammatory effects of the TAVR procedure and hypothesized that alterations in...

CU Boulder engineers and faculty from the Consortium for Fibrosis Research & Translation (CFReT) at the CU Anschutz Medical Campus have teamed up to develop biomaterial-based 鈥渕imics鈥� of heart tissues to measure patients鈥� responses to an aortic valve replacement procedure, offering new insight into the ways that cardiac tissue re-shapes...

Mycobacteria are a diverse bacterial group ubiquitous in many soil and aquatic environments. Members of this group have been associated with human and other animal diseases, including the nontuberculous mycobacteria (NTM), which are of growing relevance to public health worldwide. Although soils are often considered an important source of environmentally...

Premise Lichens are fungi that enter into obligate symbioses with photosynthesizing organisms (algae, cyanobacteria). Traditional narratives of lichens as binary symbiont pairs have given way to their recognition as dynamic metacommunities. Basidiomycete yeasts, particularly of the genus Cyphobasidium , have been inferred to be widespread and important components of lichen...

Striated muscle myosins are encoded by a large gene family in all mammals, including human. These isoforms define several of the key characteristics of the different striated muscle fiber types including maximum shortening velocity. We have previously used recombinant isoforms of the motor domains of seven different human myosin isoforms...

Understanding the contact and friction between soft materials is vital to a wide variety of engineering applications including soft sealants and medical devices such as catheters and stents. Although the mechanisms of friction between stiff materials have been extensively studied, the mechanisms of friction between soft materials are much less...

Diatoms are the most diverse lineage of algae, but the diversity of their chloroplast genomes, particularly within a genus, has not been well documented. Herein, we present three chloroplast genomes from the genus Halamphora ( H . americana , H . calidilacuna , and H . coffeaeformis ), the first...

Zinc (Zn 2+ ) is an integral component of many proteins and has been shown to act in a regulatory capacity in different mammalian systems, including as a neurotransmitter in neurons throughout the brain. While Zn 2+ plays an important role in modulating neuronal potentiation and synaptic plasticity, little is...

I just got back from the Evolution Meeting in Providence and I鈥檓 full of information and ideas for research. I had the opportunity to reconnect with past colleagues and meet some new people. Other CU Boulder folks attended, including the labs of Dan Doak, Nancy Emery, Nolan Kane, Stacy Smith,...
