Fatigue failure testing of human hair: Weibull-analysis for constant strain experiments.

Fatigue failure testing of materials is an important aspect of assessing their strength and resilience under long-term, oscillatory stresses and/or strains. This also applies to human hair. For this investigation, we decided to complement existing experience on cyclic tests at various levels of constant stress with those at various constant strains (4-30%).

Building Clinical Care Capacity for Patients With Special Pathogens in Advance of the Next Outbreak.

In response to the growing number of outbreaks of emerging infectious diseases, the US Administration for Strategic Preparedness and Response (ASPR) has embarked on a plan to improve and expand special pathogen patient care capabilities. To achieve this, ASPR is developing a coordinated network of Regional Emerging Special Pathogen Treatment Centers (RESPTCs) to serve as state-of-the-art facilities staffed by a highly trained workforce to care for and manage special pathogen patients across the lifespan. The RESPTC network represents the operational arm of a broader US National Special Pathogen System of care to prevent and prepare for the next infectious disease outbreak.

Prevalence of anti-lymphocyte IgM autoantibodies driving complement activation in COVID-19 patients.

Introduction: COVID-19 patients can develop autoantibodies against a variety of secreted and membrane proteins, including some expressed on lymphocytes. However, it is unclear what proportion of patients might develop anti-lymphocyte antibodies (ALAb) and what functional relevance they might have.

Methods: We evaluated the presence and lytic function of ALAb in the sera of a cohort of 85 COVID-19 patients (68 unvaccinated and 17 vaccinated) assigned to mild (N=63), or moderate/severe disease (N=22) groups.
