Faculty, Staff and Student Publications

Cancer genomic studies have identified frequent alterations in genes encoding components of the SWI/SNF chromatin remodeling complex, including SMARCA4 and ARID1A. Importantly, clinical reports indicate that SMARCA4-mutant lung cancers respond poorly to immunotherapy and have dismal prognosis. In this study, we corroborated the clinical findings by using immune-humanized, syngeneic, and genetically engineered mouse models of lung cancer harboring SMARCA4 deficiency. Specifically, models with SMARCA4 loss showed decreased response to anti-PD-1 immunotherapy associated with significantly reduced infiltration of dendritic cells and CD4+ T cells into the tumor microenvironment. SMARCA4 loss in tumor cells led to profound downregulation of STING1, IL1β, and …

Measuring Emotional Intelligence With The Msceit 2: Theory, Rationale, And Initial Findings, John D. Mayer, David R. Caruso, Peter Salovey, Iris Y. Lin, Braden J. Hansma, Joanna Solomon, Gill Sitarenios, Manolo Romero Escobar

UNH Personality Lab

Introduction: The model of emotional intelligence as an ability has evolved since its introduction 35 years ago. The revised model includes that emotional intelligence (EI) is a broad intelligence within the Cattell-Horn-Carroll (CHC) model of intelligence, and that more areas of problem solving are involved than originally detailed. An argument is made here that veridical scoring of EI test responses is a sound procedure relative to scoring keys based on expert consensus or a single emotion theory. To the degree that EI fits present-day theories of intelligence (i.e., the CHC model), any subsidiary factors of EI reasoning should correlate highly …

All Decisions

The court denied the tenant's motion for a stay and undertaking pending an interlocutory appeal of an order denying dismissal of a holdover petition. The court clarified that CPLR 5519(a)(6) automatic stays only apply to judgments or orders requiring enforcement, such as an eviction. Since the appealed order merely denied dismissal and transferred the case to trial, not directing any specific enforcement action against the tenant, an automatic stay was not warranted.
