Quantitative trait locus (QTL) mapping has been used to dissect the genetic architecture of complex traits and predict phenotypes for marker-assisted selection. Many QTL mapping studies in plants have been limited to one biparental family population. Joint analysis of multiple biparental families offers an alternative approach to QTL mapping with a wider(More)
Maternal iron status is thought to be related to postpartum depressive symptoms. The purpose of the present study was to evaluate the relationship between pre- and postnatal maternal iron status and depressive symptoms in pilot (n = 137) and confirmatory (n = 567) samples of Chinese women. Iron status was evaluated at mid- and late pregnancy and 3 days(More)
PURPOSE This study was designed to generate an inducible autoimmune model of keratoconjunctivitis sicca (KCS) for study of pathogenesis of the disease. METHODS Lewis rats were immunized with a mixture of lacrimal and salivary gland extract or recombinant mouse protein kallikrein 1b22 (Klk1b22) emulsified in complete Freund's adjuvant (CFA). For disease(More)
Blueberry (Vaccinium section Cyanococcus) is an important small fruit crop native to North America. Relationships among the primary species known as ‘blueberry’ has been a source of speculation due to the out-breeding nature of the crop, the use of intra-specific hybridization and open-pollinated selection in breeding programs, and the lack of genomic(More)
A previous study reported a comprehensive quantitative trait locus (QTL) and genome wide association study (GWAS) of southern leaf blight (SLB) resistance in the maize Nested Association Mapping (NAM) panel. Since that time, the genomic resources available for such analyses have improved substantially. An updated NAM genetic linkage map has a nearly(More)
Quantitative trait locus (QTL) models can provide useful insights into trait genetic architecture because of their straightforward interpretability but are less useful for genetic prediction because of the difficulty in including the effects of numerous small effect loci without overfitting. Tight linkage between markers introduces near collinearity among(More)
OBJECTIVE To analyze the impact of passing items above the roof level in the gross motor subtest of Peabody development motor scales (PDMS-2) on its assessment results. METHODS In the subtests of PDMS-2, 124 children from 1.2 to 71 months were administered. Except for the original scoring method, a new scoring method which includes passing items above the(More)
The B7/CD28 costimulatory pathway plays a critical role in T cell activation including Th1/Th2 differentiation. However, little is known about whether CD28 costimulation favors polarization of either Th1 and Th2 or both. Here, we show a critical role of the natural ligands for CD28 molecules (B7.2–Ig or B7.1–Ig fusion proteins), particularly in the(More)
