(44)Ti/(44)Sc radionuclide generators are of interest for molecular imaging. The 3.97 hours half-life of (44)Sc and its high positron branching of 94.27% may stimulate the application of (44)Sc-labeled PET radiopharmaceuticals. This review describes the current status of (44)Ti production, (44)Ti/(44)Sc radionuclide generator development, post-processing of generator eluates towards medical app...

Supply chains (SC) in an attempt to be more competitive, are adopting new management paradigm. Among these paradigms there are four that deserve particular mention because of their importance to better SC performance: lean, agile, resilient and green. The main objective of this paper is to propose a conceptual model for a lean, agile, resilience and green SC, with the purpose of improving their...

Situated cognition (SC) and knowledge maintenance are intimately connected. We say that SC motivates research into KM and KM assess SC. If knowledge is situated, then a symbolic KB will require modiica-tion as the situation changes. However, if we could demonstrate that the 5 process of change dictated by SC is tamed via current KM tools, then the case for concerning ourselves with SC becomes w...

Both the frontal eye field (FEF) in the prefrontal cortex and the superior colliculus (SC) on the roof of the midbrain participate in the generation of rapid or saccadic eye movements and both have projections to the premotor circuits of the brain stem where saccades are ultimately generated. In the present experiments, we tested the contributions of the pathway from the FEF to the premotor cir...

FSH acts via testicular Sertoli cells (Sc) bearing FSH receptor (FSH-R) for regulating male fertility. Despite an adult-like FSH milieu in infant boys and monkeys, spermatogenesis is not initiated until the onset of puberty. We used infant and pubertal monkey Sc to reveal the molecular basis underlying developmental differences of FSH-R signaling in them. Unlike pubertal Sc, increasing doses of...

The maize r locus encodes a transcription factor that regulates the developmental expression of the plant pigment anthocyanin. In an unusual example of gene regulatory diversity, the R-sc (Sc, strong seed color) and the R-p (P, plant color) alleles of r have nonoverlapping tissue specificity and nonhomologous 5' flanking sequences. Heterozygotes between wild-type P and Sc mutants with Ds6 trans...

PURPOSE Stress may play a role in explaining part of the conscientiousness-longevity relationship. Conscientiousness (C) is associated with the appraisals of stressors and its lower-order facets have been shown to differentially moderate the experience of stress in daily life. This study investigated whether the lower-order facet, self-control (SC), moderated the relationship between stress app...

The concept of in-air output ratio Sc was introduced to characterize how the incident photon fluence per monitor unit or unit time for a Co-60 unit varies with collimator settings. However, there has been much confusion regarding the measurement technique to be used that has prevented the accurate and consistent determination of Sc. The main thrust of the report is to devise a theoretical and m...

PURPOSE To evaluate the kinetics, receptor specificity, molecular basis, and site selectivity of the endocrine and neural regulation of secretory component (SC) synthesis by rat lacrimal gland acinar cells. METHODS Acinar cells from the rat lacrimal and submandibular glands, as well as epithelial cells (IEC-6) from the rat small intestine, were cultured in supplemented, serum-free media and t...
