Face Off: 3D-Printed Masks as a Cost-Effective and Reusable Alternative to N95 Respirators: A Feasibility Study.

Background: One of the best methods for protection against respiratory diseases is the use of an N95 mask. Supply shortages have demonstrated a significant need for effective alternatives to N95 masks. Benefits of 3D-printed respirators over N95s include reduced cost and ease of production, widespread availability, reusability/sterilizability, and customizability.

BreastImplantAnalyzer: An easy-to-use, validated tool for calculating breast implant volume from MRI data.

Background: Given the prevalence of breast augmentation and prosthetic-based breast reconstruction, it is common for the plastic surgeon to see patients presenting for revisional implant surgery. A frequent issue encountered in such procedures is uncertainty of implant size, which presents numerous challenges and may lead to undesired outcomes for both the patient and the surgeon. There is currently no tool available with the purpose of measuring implant volume from magnetic resonance imaging (MRI) data.

DRRGenerator: A Three-dimensional Slicer Extension for the Rapid and Easy Development of Digitally Reconstructed Radiographs.

As the interest in image-guided medical interventions has increased, so too has the necessity for open-source software tools to provide the required capabilities without exorbitant costs. A common issue encountered in these procedures is the need to compare computed tomography (CT) data with X-ray data, for example, to compare pre-operative CT imaging with intraoperative X-rays. A software approach to solve this dilemma is the production of digitally reconstructed radiographs (DRRs) which computationally simulate an X-ray-type image from CT data.

Anabolic action of parathyroid hormone is skeletal site specific at the tissue and cellular levels in mice.

The cellular and molecular events triggering the anabolic response of the skeleton to exogenous parathyroid hormone (PTH) are not well understood. Despite the numerous bone mass studies in rats, few data are available for mice. Therefore, we treated 10-week-old female intact C57BL/6J mice with human PTH(1-34) delivered subcutaneously at a dose of 40 microg/kg per day 5 days a week for 3 weeks and 7 weeks.
