    Abstract The advent of immune checkpoint inhibition has pushed the treatment paradigm for resectable non-small-cell lung cancer (NSCLC) toward neoadjuvant therapy. A growing number of promising trials have examined the utility of neoadjuvant immunotherapy, both alone and in combination with other modalities such as radiation therapy (RT) and chemotherapy. The phase II LCMC3 and NEOSTAR trials demonstrated a role for neoadjuvant immunotherapy in inducing meaningful pathologic responses, and another phase II trial established the feasibility of combining neoadjuvant durvalumab with RT. Significant interest in neoadjuvant chemoimmunotherapy resulted in the conduct of multiple successful phase II trials including the Columbia trial, NADIM, SAKK 16/14, and NADIM II. Across these trials, neoadjuvant chemoimmunotherapy led to high rates of pathologic response and improved surgical outcomes without compromising surgical timing or feasibility. CheckMate-816, which was a randomized phase III trial studying neoadjuvant nivolumab in addition to chemotherapy, definitively established a benefit for neoadjuvant chemoimmunotherapy compared to chemotherapy alone for resectable NSCLC. Despite the growing literature and success of these trials, several outstanding questions remain, including the relationship between pathologic response and patient survival, the role of biomarkers such as programmed death ligand 1 and circulating tumor DNA in determining patient selection and treatment course, and the utility of additional adjuvant therapies. Longer follow-up of CheckMate-816 and other ongoing phase III trials may help address these questions. Ultimately, the complexity of managing resectable NSCLC highlights the importance of a multidisciplinary approach to patient care.

    Abstract FKBP, a naturally occurring ubiquitous intracellular protein, has been proposed as a potential target for coronavirus replication. A non-immunosuppressive FKBP ligand, FK1706, was studied in vitro in a Vero cell model to assess potential activity alone and in combination with antivirals against SARS-CoV-2 replication. When combined with remdesivir, synergistic activity was seen (summary synergy score 24.7±9.56). FK1706 warrants in vivo testing as a potential new combination therapeutic for the treatment of COVID-19 infections.

    Abstract Human induced pluripotent stem cells (hiPSCs) are characterized by unlimited self-renewal and the capability to differentiate into all three germ layers, with the potential to further differentiate into all types of cells and tissues. Human iPSCs retain all genetic information from their original donors and can be developed into disease models to study disease pathophysiology, identify disease phenotypes and biomarkers, and evaluate therapeutic efficacy and toxicity for drug development. Human iPSCs can also be used to develop cell therapies and regenerative medicine. In the last decade, the technologies for hiPSC generation and differentiation have advanced rapidly. Human iPSC culture and propagation are tedious and require careful handling. High-quality hiPSCs are necessary for downstream applications. The methods, techniques, and skills for hiPSC maintenance and characterization are very different from those for immortalized cell lines. It can be a challenge for new laboratory staff, and sometimes even for experienced staff, to properly culture and maintain the high quality of these cells. Here, we describe a comprehensive set of protocols for hiPSC propagation under chemically defined and feeder-free culture conditions. These step-by-step protocols describe in detail all the reagents and experimental procedures needed to culture hiPSCs. The protocols also describe experimental methods for hiPSC characterization, including immunofluorescence staining and flow cytometric analysis with a panel of pluripotency markers, a teratoma formation assay for validation of in vivo pluripotency, and detection of Sendai virus to ensure elimination of the viral vectors. These protocols have been successfully used in our laboratory for hiPSC expansion and propagation, and this article provide a useful reference guide for laboratory staff to work on hiPSC culture. Published 2023. This article is a U.S. Government work and is in the public domain in the USA. Current Protocols published by Wiley Periodicals LLC. Basic Protocol 1: Propagation and cryopreservation of hiPSC cultures Basic Protocol 2: Recovery of cryopreserved hiPSCs Basic Protocol 3: Validation of pluripotency markers via immunocytochemical analysis Alternate Protocol: Determination of the expression of pluripotency markers via flow cytometry analysis Basic Protocol 4: Assessment of pluripotency via in vivo teratoma formation assay Basic Protocol 5: Confirmation of Sendai viral vector clearance via RT-PCR.

    Abstract Objective: Previous literature has indicated a strong negative correlation between the moral foundation of purity/sanctity and vaccination rates. The current research investigated how purity concerns impact COVID-19 vaccination hesitancy and tested an information intervention to bolster vaccination intention among people with purity concerns.
    Method: Study 1 surveyed 566 Republicans and Republican-leaning Independents in the United States. Study 2 was a between-subject-designed survey experiment that investigated the impact of three statements on the COVID-19 vaccination attitudes and intentions of 637 Republicans and Republican-leaning Independents. Statement 1 argued that vaccines are not impure from a scientific perspective; Statement 2 made the same argument with quotes from the Bible; and Statement 3 was a control statement.
    Results: Study 1 established a significant correlation between the existence of vaccination history and purity as a moral foundation. Study 2 found that among those with no COVID-19 vaccination history, statements arguing that vaccines are not impure from either a scientific perspective or a religious perspective improved attitudes toward vaccination and intention to get vaccinated.
    Conclusion: Purity concerns can be leveraged as a way to bolster vaccination rates, especially among conservatives. However, the impurity perception only mediated the causal relationship between the treatment and the attitude toward vaccines (but not the actual intention), suggesting that changes in the actual vaccination behavior are subject to factors other than purity concerns.

    Abstract Purpose: Saliency models that predict observers' visual attention to facial differences could enable psychosocial interventions to help patients and their families anticipate staring behaviors. The purpose of this study was to assess the ability of existing saliency models to predict observers' visual attention to acquired facial differences arising from head and neck cancer and its treatment.
    Approach: Saliency maps predicted by graph-based visual saliency (GBVS), an artificial neural network (ANN), and a face-specific model were compared to observer fixation maps generated from eye-tracking of lay observers presented with clinical facial photographs of patients with a visible or functional impairment manifesting in the head and neck region. We used a linear mixed-effects model to investigate observer and stimulus factors associated with the saliency models' accuracy.
    Results: The GBVS model predicted many irrelevant regions (e.g., shirt collars) as being salient. The ANN model underestimated observers' attention to facial differences relative to the central region of the face. Compared with GBVS and ANN, the face-specific saliency model was more accurate on this task; however, the face-specific model underestimated the saliency of deviations from the typical structure of human faces. The linear mixed-effects model revealed that the location of the facial difference (midface versus periphery) was significantly associated with saliency model performance. Model performance was also significantly impacted by interobserver variability.
    Conclusions: Existing saliency models are not adequate for predicting observers' visual attention to facial differences. Extensions of face-specific saliency models are needed to accurately predict the saliency of acquired facial differences arising from head and neck cancer and its treatment.

    Abstract Coronavirus disease 2019 (COVID-19) is a novel disease caused by the severe acute respiratory syndrome coronavirus (SARS-CoV)-2 virus that was first detected in December of 2019 in Wuhan, China, and has rapidly spread worldwide. The search for a suitable vaccine as well as effective therapeutics for the treatment of COVID-19 is underway. Drug repurposing screens provide a useful and effective solution for identifying potential therapeutics against SARS-CoV-2. For example, the experimental drug remdesivir, originally developed for Ebola virus infections, has been approved by the US Food and Drug Administration as an emergency use treatment of COVID-19. However, the efficacy and toxicity of this drug need further improvements. In this review, we discuss recent findings on the pathology of coronaviruses and the drug targets for the treatment of COVID-19. Both SARS-CoV-2-specific inhibitors and broad-spectrum anticoronavirus drugs against SARS-CoV, Middle East respiratory syndrome coronavirus, and SARS-CoV-2 will be valuable additions to the anti-SARS-CoV-2 armament. A multitarget treatment approach with synergistic drug combinations containing different mechanisms of action may be a practical therapeutic strategy for the treatment of severe COVID-19. SIGNIFICANCE STATEMENT: Understanding the biology and pathology of RNA viruses is critical to accomplish the challenging task of developing vaccines and therapeutics against SARS-CoV-2. This review highlights the anti-SARS-CoV-2 drug targets and therapeutic development strategies for COVID-19 treatment.
