Bone fragility fractures are caused by low bone mass or impaired bone quality. Osteoblast/osteoclast coordination determines bone mass, but the factors that control bone quality are poorly understood. Osteocytes regulate osteoblast and osteoclast activity on bone surfaces but can also directly reorganize the bone matrix to improve bone quality through...

As we move into the era of personalized medicine, it may not be too far off that a visit to our doctor includes a number of genome-scale 鈥渟eq鈥� experiments to diagnose disease and estimate our likelihood of response to an array of possible treatments. One such experiment measures the cell鈥檚...

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...

兔子先生传媒文化作品 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...

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...

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...
