Wnt signaling is involved in self-renewal and maintenance of hematopoietic stem cells (HSCs); however, the particular role of noncanonical Wnt signaling in regulating HSCs in vivo is largely unknown. Here, we show Flamingo (Fmi) and Frizzled (Fz) 8, members of noncanonical Wnt signaling, both express in and functionally maintain quiescent long-term HSCs. Fmi regulates Fz8 distribution at the in...

OBJECTIVE Postnatal tissue accretion in preterm infants differs from those in utero, affecting body composition (BC) and lifelong morbidity. Length normalized BC data allows infants with different body lengths to be compared and followed longitudinally. This study aims to analyze BC of preterm and term infants during the first six months of life. METHODS The BC data, measured using dual energ...

OBJECTIVE To assess the levels of adiposity and physical activity among Saudi preschool children from Jeddah. METHODS Participants included 224 Saudi preschool children, randomly selected from public and private preschools in Jeddah during April and May of 2006, using a multistage stratified sampling technique. Measurements included weight, height, body mass index, triceps and subscapular ski...

Early excessive weight gain is positively associated with later obesity, and yet the effect of weight gain during specific periods and the impact of infant feeding practices are debated. The objective of the present study was to examine the impact of weight gain in periods of early childhood on body composition at 3 years, and whether infant feeding modified the relationship between early growt...

This paper describes the extension of a building management system with an interface that allows the import of simulation models, control, and fault detection (FDD) algorithms. This interface is based on the Functional Mock-up Interface (FMI), and the Building Automation Java Architecture (Baja) standards. This allows HVAC designers and control vendors a) developing, testing and improving contr...

Molecular imaging, including fluorescence imaging (FMI), bioluminescence imaging (BLI), positron emission tomography (PET), single-photon emission-computed tomography (SPECT), and computed tomography (CT), has a pivotal role in the process of tumor and relevant drug research. CT, especially Micro-CT, can provide the anatomic information for a region of interest (ROI); PET and SPECT can provide ...

We report a study of enhancing the magnetic ordering in a model magnetically doped topological insulator (TI), Bi(2-x)Cr(x)Se(3), via the proximity effect using a high-TC ferrimagnetic insulator Y(3)Fe(5)O(12). The FMI provides the TI with a source of exchange interaction yet without removing the nontrivial surface state. By performing the elemental specific X-ray magnetic circular dichroism (X...

BACKGROUND Body mass index (BMI) does not make a distinction between fat mass and lean mass. In children, high fat mass appears to be associated with low maternal education, as well as low lean mass because maternal education is associated with physical activity. Therefore, BMI might underestimate true obesity in children of low-educated mothers. OBJECTIVE To investigate the associations of m...

assessment of the reservoir structure and determination of theinsitu stress direction arenecessary in oil production optimization andfield development. today, the application of reservoir software and image logsplay a central role in resolving this problem. electricand ultrasonic imaging tools record vast amounts of high-resolution data within the borehole wall. this enables the geoscientists t...

Raising the thermoelectric voltage in spin generators is an important subject. We investigated substitution of bismuth for yttrium to increase pumping at paramagnetic metal and ferrimagnetic insulator (PM/FMI) interface, tested bismuth-substituted iron garnet films grown by liquid phase epitaxy. Epitaxial Bi-substituted exhibit large growth-induced magnetic anisotropy perpendicular film surface...
