OBJECTIVES We aimed to examine associations between each of three leisure activities (Cognitive, Physical, and Social) and performance in selected cognitive domains (Speed, Memory, Verbal ability, and Executive functions) and global cognition. We also aimed to explore associations between medical and health factors and late-life cognition. METHOD Our sample comprised 119 pairs of monozygotic ...
OBJECTIVE The purpose of this study was to evaluate the impact of noncentral placental cord insertion on birthweight discordance in twins. STUDY DESIGN We performed a multicenter, prospective trial of twin pregnancies. Placental cord insertion was documented as central, marginal, or velamentous according to a defined protocol. Association of the placental cord insertion site with chorionicity...
Inferences about species boundaries and evolutionary history are often complicated by discordance between datasets. In recent times, considerable effort has been devoted to understanding the causes of discordance between the patterns of genetic variation and structure shown by different unlinked molecular markers. The genus Batrachoseps (Caudata, Plethodontidae), the most diverse group of salam...
BACKGROUND Discordance between fractional flow reserve (FFR) and coronary flow velocity reserve (CFVR) may reflect important coronary pathophysiology but usually remains unnoticed in clinical practice. We evaluated the physiological basis and clinical outcome associated with FFR/CFVR discordance. METHODS AND RESULTS We studied 157 intermediate coronary stenoses in 157 patients, evaluated by F...
Molecular biomarkers are used by clinicians to guide selection of the most appropriate systemic therapy for metastatic breast cancer: endocrine therapy, chemotherapy, or human epidermal growth factor receptor 2 (HER2) – targeted therapy, such as trastuzumab or lapatinib. With increased understanding that molecular biomarker status can change during tumor progression such that biomarker status i...
PURPOSE To report genetic and phenotypic discordance across two generations of a family with autosomal recessive Stargardt disease (STGD1) and to compare pathogenicities of the G1961E and A1038V alleles of the ATP-binding cassette transporter, subfamily A, member 4 (ABCA4) gene. METHODS Five members of a family with STGD1 (patients 1-4, affected; patient 5, carrier) were included. Clinical as...
