    Abstract Seven constituents were isolated from the stems of Lawsonia alba Lam., following an activity-guided isolation, which include two new constituents, namely lawsorosemarinol (1) and lawsofructose (2), one known compound 2-(β-d-glucopyranosyloxy)-1, 4-naphthoquinone (3) and four compounds, 4-hydroxy coumarine (4), 3-(4-hyroxyphenyl)-triacontyl-(Z)-propenoate (5), 3-(4-hydroxy-3-methoxyphenyl)-triacontyl-(Z)-propenoate (6) and 7-hydroxy-4-methyl coumarin (7) first time isolated from Lawsonia alba. Their structure elucidation was based on spectroscopic data analyses. Compounds 3 and 7 showed a moderate inhibition of urease activity, while rest of them showed less than 50% inhibition. These compounds did not show any significant inhibition against α-chymotrypsin.

    Abstract Diffuse alveolar hemorrhage (DAH) is described as the collection of blood in alveolar spaces caused by damaged pulmonary vasculature. It often presents as a life-threatening medical emergency that requires urgent medical intervention along with timely diagnosis and management of the underlying cause. We hereby report a 19-year-old female who presented with clinical and radiological characteristics consistent with DAH.

    Abstract Background: Health disparities and the unequal distribution of social resources impact health outcomes. By considering social determinants of health (SDH), clinicians can provide holistic and equitable care. However, barriers such as lack of time or understanding of the relevance of SDH to patient care prevent providers from addressing SDH. Simulation curricula may improve learners' ability to address SDH in practice.
    Objectives: The primary objective was to increase the percentage of pediatric emergency simulations that included SDH objectives from 5% to 50% in 12 months at one institution. As a balancing metric, we examined whether trainees approved the incorporation of SDH objectives.
    Methods: Using the Model for Improvement approach, we conducted interviews of residents and simulation facilitators to identify challenges to integrating SDH objectives into the simulation curriculum. Review of interviews and visual representation of the system helped identify key drivers in the process. A team of simulation leaders, residents, and fellows met regularly to develop simulation cases with embedded SDH objectives. Using a plan, do, study, act approach, we tested, refined, and implemented interventions including engaging residency program and SDH leadership, piloting cases, providing facilitators concise resources, inviting SDH-specific experts to co-debrief, and eliciting and incorporating learner and facilitator feedback to improve cases. SDH topics include homelessness, undocumented status, and racism.
    Results: Prior to the start of the quality improvement work, SDH were rarely incorporated into emergency simulations for pediatric residents. A p-chart was used to track the percentage of monthly cases that incorporated SDH topics. During the study period, the percentage of simulations including SDH topics increased to 57% per month. Most trainees (94%) welcomed incorporating SDH objectives.
    Conclusions: Using the Model for Improvement, we incorporated SDH objectives into pediatric resident emergency simulations. Next steps include examining effectiveness of the curriculum, dissemination to additional learners, and examining sustainability in practice.

    Abstract Co-immunoprecipitation can be utilized to study protein-protein interactions from various environments, cell types, or tissues. Herein, we describe a co-immunoprecipitation protocol that can be used to examine protein complexes found in the pathogenic spirochete Borrelia burgdorferi. The method outlined here has successfully identified known and unknown members of borrelial protein complexes and is an efficient method for studying protein interactions in this pathogenic spirochete.
