Primer on Video-oculography and Video Head Impulse Testing for Neurologists

Abstract Purpose of Review Eye Movement and Vestibular findings can be manifestations of a wide range of neurologic diseases including and beyond those associated with peripheral vestibular dysfunction. Video-oculography (VOG) and video head impulse testing (vHIT) are accessible,...

A model for the epidemiological impact of tuberculosis policy options.

Objective: To develop a new tuberculosis transmission model, addressing the limitations of and building on the TB Impact Model and Estimates software tool, to enable decision-makers to assess the impact of various tuberculosis interventions and allocate resources more effectively...

Cost comparison of community-based vector surveillance using VectorCamTM, an AI-enabled mosquito identification tool, versus routine entomological surveillance in Uganda

Abstract Background National malaria elimination programs depend on timely and reliable vector surveillance data to guide interventions. Current systems rely on analog data collection and microscopy-based morphological identification of mosquitoes by entomologists (vector control...

Protocol for optogenetic stimulation of cells under physical confinement

Optogenetic approaches enable spatiotemporal control of signaling proteins, yet their integration with microfluidic assays to study confined cell migration remains challenging. Herein, we present a protocol for the optogenetic activation of PI3K/Akt signaling in confined cells. W...

Plasma wave observations from Juno spacecraft at the Jovian bow shock

Recent observations of Jupiter’s bow shock have provided new insights into the energy dissipation mechanisms associated with bow shocks of outer planets. At greater distances from the Sun, the typically increasing super-Alfvénic nature of the solar wind leads to higher-energy bow...

Guns and Perceptions of Safety Among US Women

Importance: Prior research found differences in the perceived safety benefits from firearm exposure among diverse gun owners. More women have bought firearms in recent years, resulting in a growing proportion of women who own guns. Objective: To examine differences in perceptions...

Risk factors and predictors for botulinum toxin type A reinjection within six months in patients with acute acquired concomitant esotropia

BACKGROUND: To identify independent risk factors and predictors for botulinum toxin type A (BTA) reinjection within 6 months in acute acquired concomitant esotropia (AACE) patients, providing a scientific foundation for risk-stratified clinical management. METHODS: In this case-c...
