BACKGROUND AND PURPOSE The hand motor cortex (HMC) has been classically described as having an omega or epsilon shape in axial-plane images obtained with CT and MR imaging. The aim of this study was to use MR imaging and Talairach normalization in a large sample population that was homogeneous for age and handedness to evaluate in a sex model a new classification with 5 morphologic variants of ...

Four Zn(II)-tetra(carboxyphenyl)porphyrins in solution and bound to metal oxide (TiO2, ZnO, and ZrO2) nanoparticle films were studied to determine the effect of the spacer length and anchoring group position (para or meta) on their binding geometry and photoelectrochemical and photophysical properties. The properties of three types of anchoring groups (COOH and COONHEt3) for four Zn(II)-porphyr...

BACKGROUND: 5-Methylcytosine (5-mC) is an important epigenetic modification involved in development and is frequently altered in cancer. 5-mC can be enzymatically converted to 5-hydroxymethylcytosine (5hmC). 5-hmC modifications are known to be prevalent in DNA of embryonic stem cells and neurons, but the distribution of 5-hmC in human liver tumor and matched control tissues has not been rigorou...

We discuss an instability in the leapfrog integration algorithm, widely used in current Hybrid Monte Carlo (HMC) simulations of lattice QCD. We demonstrate the instability in the simple harmonic oscillator (SHO) system where it is manifest. We demonstrate the instability in HMC simulations of lattice QCD with dynamical Wilson-Clover fermions and discuss implications for future simulations of la...

This introduction to the volume discusses evolving field of Human-Machine Communication (HMC), drawing on insights from philosophy science. We explore critical debates in field, underscoring importance challenging assumptions, embracing interfield work, and fostering dialogue shaping our understanding HMC. Moreover, we celebrate vibrant collaboration between disciplines that drives progress pie...

Regolith characterization in its entirety is particularly difficult gneissic regoliths due to the heterogeneity of their rock structure. Rare earth elements (REE) are a useful tool helping understand evolution regoliths. This study relates mineralogy and weathering indexes three gneisses (P1-leucocratic, P2-mesocratic P3-melanocratic gneisses) distribution REE at depth. In soil, clay activity, ...

Epigenetic dysregulation of gene expression is thought to be critically involved in the pathophysiology of Alzheimer's disease (AD). Recent studies indicate that DNA methylation and DNA hydroxymethylation are 2 important epigenetic mechanisms that regulate gene expression in the aging brain. However, very little is known about the levels of markers of DNA methylation and hydroxymethylation in t...

OBJECTIVE To determine the influence of thrombin, which is generated intraperitoneally during peritoneal dialysis, on the synthesis of fibrinolytic system components in human peritoneal mesothelial cells (HMC). METHODS Confluently grown HMC, isolated from the omental tissue, were used in the experiments. Conditioned media were obtained by incubating cells with serum-free M199 containing the a...

The DNA demethylation pathway has been discovered to play a significant role in DNA epigenetics. This pathway removes the methyl group from cytosine, which is involved in the oxidation of 5-methylcytosine to 5-hydroxymethylcytosine (5-hmC) by ten-eleven translocation (TET) proteins. Then, 5-hmC can be iteratively oxidized to generate 5-formylcytosine (5-foC) and 5-carboxylcytosine (5-caC). Howe...

Several fibroblast growth factors (FGFs) are able to reduce and improve radiation-induced tissue damage through the activation of surface fibroblast growth factor receptors (FGFRs). In contrast, some FGFs lack classical signal sequences, which play roles in the release of FGFs, and the intracellular function of these FGFs is not well clarified. In this study, we evaluated the transcript levels ...
