Pregnancy-associated cardiomyopathy in survivors of childhood cancer

Current information regarding pregnancy-associated cardiomyopathy among women treated for childhood cancer is insufficient to appropriately guide counseling and patient management. This study aims to characterize its prevalence within a large cohort of females exposed to cardiotoxic therapy

Cardiac outcomes in a cohort of adult survivors of childhood and adolescent cancer: retrospective analysis of the Childhood Cancer Survivor Study cohort

Objectives To assess the incidence of and risks for congestive heart failure, myocardial infarction, pericardial disease, and valvular abnormalities among adult survivors of childhood and adolescent cancers

β1A Integrin Is a Master Regulator of Invadosome Organization and Function

Use of patterned surfaces, reverse genetics, and time-controlled photoinactivation showed that β1 but not β3 integrins are required for invadosome formation, self-assembly, and stabilization into a ring structure. The activation state of β1 as well as its phosphorylation by protein kinase C on Ser785 control these process and link to the degradative function

Killer cell immunoglobulin-like receptor 3DL1 polymorphism defines distinct hierarchies of HLA class I recognition

Natural killer (NK) cells play a key role in immunity, but how HLA class I (HLA-I) and killer cell immunoglobulin-like receptor 3DL1 (KIR3DL1) polymorphism impacts disease outcome remains unclear. KIR3DL1 (*001/*005/*015) tetramers were screened for reactivity against a panel of HLA-I molecules. This revealed different and distinct hierarchies of specificity for each KIR3DL1 allotype, with KIR3DL1*005 recognizing the widest array of HLA-I ligands. These differences were further reflected in functional studies using NK clones expressing these specific KIR3DL1 allotypes. Unexpectedly, the Ile/Thr80 dimorphism in the Bw4-motif did not categorically define strong/weak KIR3DL1 recognition. Although the KIR3DL1*001, *005, and *015 polymorphisms are remote from the KIR3DL1-HLA-I interface, the structures of these three KIR3DL1-HLA-I complexes showed that the broader HLA-I specificity of KIR3DL1*005 correlated with an altered KIR3DL1*005 interdomain positioning and increased mobility within its ligand-binding site. Collectively, we provide a generic framework for understanding the impact of KIR3DL1 polymorphism on the recognition of HLA-I allomorphs

Eight Million Points Per Day: Archaeological Implications of Laser Scanning and Three-Dimensional Modeling of Pu'ukohola Heiau, Hawai'i Island

Recent applications of three-dimensional modeling in archaeology have become more widespread in recent years for site-based and landscape approaches. The authors perform a three-dimensional analysis of Pu 'ukoholii Heiau, using data collected with a Cyrax laser scanner. By examining the three-dimensional model, surface area and volumetric calculations are made. These calculations are used to estimate labor input based on experimental data collected in a previous study of excavated Maui heiau and producing similar results without need for excavation
