When individuals learn facts (e.g., foreign language vocabulary) over multiple study sessions, the temporal spacing of study has a significant impact on memory retention. Behavioral experiments have shown a nonmonotonic relationship between spacing and retention: short or long intervals between study sessions yield lower cued-recall accuracy than intermediate intervals. Appropriate spacing of s...

This study aimed to assess the effect of intracellular prolactin (ICPRL) and hyperprolactinemia on cell replication, using an immunohistochemical (IHC) technique for Ki-67 and Mcm-2, and angiogenesis, using IHC for endoglin CD-105, in central nervous system (CNS) tumors. This cross-sectional study included 79 cases of surgically excised primary CNS tumors of neuroepithelial origin (41.8% of all...

BACKGROUND The origin recognition complex (ORC) and the minichromosome maintenance (MCM) protein complex were initially discovered in yeast and shown to be essential for DNA replication. Homologues of ORC and MCM proteins exist in higher eukaryotes, including Xenopus. The Xenopus MCM proteins and the Xenopus homologues of Saccharomyces cerevisiae Orc 1p and Orc2p (XOrc1 and XOrc2) have recently...

The MCM (minichromosome maintenance) proteins of archaea are widely believed to be the replicative DNA helicase of these organisms. Most archaea possess a single MCM orthologue that forms homo-multimeric assemblies with a single hexamer believed to be the active form. In the present study we characterize the roles of highly conserved residues in the ATPase domain of the MCM of the hyperthermoph...

The MCM (minichromosome maintenance) complex is a helicase which is essential for DNA replication. Recent results suggest that the MCM helicase is important for replication fork integrity, and may function as a target of the replication checkpoint. Interactions between MCM proteins, checkpoint kinases, and repair and recovery proteins suggest that MCMs are proximal effectors of replication fork...

Manganese (?) complex with 2, 2? bipyridine, 1, 1? dioxide (bpdo) ligand was immobilized within nanoreactors of MCM-41. The immobilized complex was characterized by powder x-ray diffraction (XRD), nitrogen adsorption desorption, and FTIR. The pore volume, surface area and pore diameter of MCM-41 decreased after immobilization of Mn complex. Three bands observed at 1250, 1220 cm?1 and 757 cm?1 a...

Every year, the Consortium for Mathematics and its Applications (C C C OMA OMA OMA P P P) sponsors the Mathematical Contest in Modeling (MCM), an international contest for undergraduates. We will discuss our strategy for developing models, writing the paper, the contest timeline, and team dynamics. 1 What is the MCM? In the MCM, three-person teams are given 96 hours to develop mathematical mode...

Zeolite A and MCM-41 have extensive applications in basic science, petrochemical science, energy conservation/storage, medicine, chemical sensor, air purification, environmentally benign composite structure and waste remediation. However, the use of zeolite A and MCM-41 in these areas, especially environmental remediation, are restricted due to prohibitive production cost. Efficient recycling o...

HIGHLIGHTS Fe incorporation significantly accelerated the adsorption of CPX on MCM-41.Fe leaching can be ignored when pH was higher than 4.0.pH played an important role in CPX adsorption on Fe-MCM-41.Co-effect of CPX and metal cations on Fe-MCM-41 was investigated. Fe-MCM-41s with various molar ratios of silicon to iron (20, 40, 80, and 160) were prepared to investigate adsorption properties of...
