Regional Variability in Compressive Strength of the Cartilaginous Nasal Septum: Implications for Fracture Patterns.

Introduction: Septal trauma is caused by compressive forces. Defining regional variability in compressive strength (CS) may reveal areas of weakness in the septum that are more prone to fracture. The objective of this study is to determine the CS at multiple locations within the cartilaginous septum and assess if variations in strength correlate with known patterns of septal fracture.

The epidemiology of alcohol involved facial injuries.

Purpose: Alcohol use has been shown to affect injury patterns and risk of trauma. This study aims to characterize the epidemiologic characteristics of alcohol involved facial injuries presenting to US emergency departments.

Methods: This study reports a cross-sectional analysis of patients with facial injuries within the National Electronic Injury Surveillance System (NEISS).

Protocol for effective surface passivation for single-molecule studies of chromatin and topoisomerase II.

For single-molecule studies requiring surface anchoring of biomolecules, poorly passivated surfaces can result in alterations of biomolecule structure and function that lead to artifacts. Here, we present a surface passivation assay for single-molecule studies of chromatin and topoisomerase II. We detail steps for preparing a nucleosome array and hydrophobic nitrocellulose-coated flow cell.

Tunable elliptical cylinders for rotational mechanical studies of single DNA molecules.

The angular optical trap (AOT) is a powerful technique for measuring the DNA topology and rotational mechanics of fundamental biological processes. Realizing the full potential of the AOT requires rapid torsional control of these processes. However, existing AOT quartz cylinders are limited in their ability to meet the high rotation rate requirement while minimizing laser-induced photodamage.

Orbital Trauma Epidemiologic Characteristics by Life Stage.

Study Design: Retrospective database review.

Objective: This study aims to characterize and compare the epidemiological factors of orbital trauma between life stages by utilizing the National Electronic Injury Surveillance System (NEISS), a nationally representative database.

Methods: The NEISS was queried for orbital injuries from 2013 to 2022.
