Two- and Three-Dimensional Culture Systems: Respiratory In Vitro Tissue Models for Chemical Screening and Risk-Based Decision Making.

Risk of lung damage from inhaled chemicals or substances has long been assessed using animal models. However, New Approach Methodologies (NAMs) that replace, reduce, and/or refine the use of animals in safety testing such as 2D and 3D cultures are increasingly being used to understand human-relevant toxicity responses and for the assessment of hazard identification. Here we review 2D and 3D lung models in terms of their application for inhalation toxicity assessment.

Voices of Frontline Leaders: Challenges and Opportunities from Frontline Primary Care Clinic Leaders in a Safety-Net Health Care System.

Background: Burnout, disengagement, and turnover among clinicians is a major challenge for the US health care industry. Research has shown that higher direct supervisor leadership scores correlate with decreased provider burnout and increased professional fulfillment. Safety-net health systems such as Federally Qualified Health Centers (FQHCs) face increased challenges due to limited financial resources, more complex social determinants of health among patients, and often fewer physician leaders who can serve as mentors compared to large, integrated health systems.

Mixed representations of choice direction and outcome by GABA/glutamate cotransmitting neurons in the entopeduncular nucleus.

The basal ganglia (BG) are an evolutionarily conserved and phylogenetically old set of sub-cortical nuclei that guide action selection, evaluation, and reinforcement. The entopeduncular nucleus (EP) is a major BG output nucleus that contains a population of GABA/glutamate cotransmitting neurons (EP) that specifically target the lateral habenula (LHb) and whose function in behavior remains mysterious. Here, we use a probabilistic switching task that requires an animal to maintain flexible relationships between action selection and evaluation to examine when and how GABA/glutamate cotransmitting neurons contribute to behavior.

Recalcitrant Bilateral Volar Hand Burn Contracture in a Toddler Treated With Integra and Staged Full-thickness Skin Graft: A Literature Review.

Background: Recurrent burn contractures on the volar aspect of the hand present a formidable challenge, especially in the pediatric patient. We used Integra followed by staged full-thickness skin grafting for recurrent bilateral volar hand burn contracture in a toddler. We reviewed the literature to appraise the utility of full-thickness skin graft (FTSG) combined with Integra used for volar hand contractures.

Tillage type and sentinel insect species affect the relative prevalence of the entomopathogenic fungus, Metarhizium robertsii, in soil.

Because the use of synthetic agrochemicals is generally not allowed in organic crop production systems, growers rely on natural substances and processes, such as microbial control, to suppress insect pests. Reduced tillage practices are associated with beneficial soil organisms, such as entomopathogenic fungi, that can contribute to the natural control of insect pests. The impacts of management, such as tillage, in a cropping system can affect soil biota in the current season and can also persist over time as legacy effects.
