3D-Printed Polymeric Biomaterials for Health Applications.

3D printing, also known as additive manufacturing, holds immense potential for rapid prototyping and customized production of functional health-related devices. With advancements in polymer chemistry and biomedical engineering, polymeric biomaterials have become integral to 3D-printed biomedical applications. However, there still exists a bottleneck in the compatibility of polymeric biomaterials with different 3D printing methods, as well as intrinsic challenges such as limited printing resolution and rates.

Measuring X-Chromosome inactivation skew for X-linked diseases with adaptive nanopore sequencing.

X-linked genetic disorders typically affect females less severely than males owing to the presence of a second X Chromosome not carrying the deleterious variant. However, the phenotypic expression in females is highly variable, which may be explained by an allelic skew in X-Chromosome inactivation. Accurate measurement of X inactivation skew is crucial to understand and predict disease phenotype in carrier females, with prediction especially relevant for degenerative conditions.

COVID-19 Pandemic Effects on the Activity Levels of Yucatan Mini-Swine (Sus scrofa domesticus).

During the COVID-19 pandemic, unexpected activity patterns emerged among Yucatan mini-swine models for heart failure and atrial fibrillation. As part of our laboratory research, we tracked activity data by FitBark™ collars that the Yucatan mini-swine wore. Previously, staff engaged with the swine daily, such as applying lotion and conducting 6-min treadmill runs.

Heart Failure in Older People Part 1: Disease State Review and Lifestyle Interventions.

The care for patients with heart failure (HF) has evolved greatly over the past decade. While new guidelines have provided more clarity on categorization and staging, and novel agents have been approved for use, there are still questions surrounding the optimal strategies as they relate to diet and exercise. Additionally, overall health care costs have increased for patients, driven in part by medication therapy.
