The class A macrophage scavenger receptor (MSR-A) is a multifunctional trimeric glycoprotein involved in innate immune response as well as the development of lipid-laden foam cells during atherosclerosis. The MSR ligand, oxidized low density lipoprotein (oxLDL), is known to be cytotoxic to macrophages and other cell types. This study examined whether MSR mediates or modulates oxLDL-induced apop...

A high performance magnetically-shielded room (MSR) has been built by Imedco, to house a 4-D MEG system, containing both gradiometers and magnetometers (Vectorview). The MSR consists of three nested enclosures, each consisting of a high-permeability magnetic layer plus an aluminum layer, where special care was given to the junctions of the inner aluminum layer. Measurements of the passive shiel...

Compact reformers (CRs) are promising devices for efficient fuel processing. In CRs, a thin solid plate is sandwiched between two catalyst layers to enable efficient heat transfer from combustion duct to the reforming duct for fuel processing. In this study, a 2D heat and mass transfer model is developed to investigate the fundamental transport phenomenon and chemical reaction kinetics in a CR ...

Guanidinium borohydride (GBH) was structurally characterized by single-crystal X-ray diffraction and found to release more than 10 wt% H(2) as a fairly pure stream during a self-sustaining thermal decomposition reaction both with and without additives that were identified to reduce the concentration of the main ammonia impurity and control the reaction sustainability.

The aim of this study was to investigate if children's early responsiveness toward social partners is developmentally related to their growing concept of self, as reflected in their mirror self-recognition (MSR) and delayed self-recognition (DSR). Thus, a longitudinal study assessed infants' responsiveness (e.g., smiling, gaze) toward social partners during the still-face (SF) task and a social...

The involvement of inhibitory transmitters for Ptychodiscus brevis toxin (PbTx)-induced depression of spinal synaptic transmission in neonatal rats was investigated. Stimulation of a dorsal root evoked monosynaptic reflex (MSR) and polysynaptic reflex (PSR) potentials in the segmental ventral root. The PbTx depressed the reflexes in a concentration-dependent manner and this depression was block...

A minor population of wild strains of Escherichia coli contains a retron, a retroelement responsible for the synthesis of multicopy single-stranded DNA (msDNA). The retron is a genetic element consisting of the gene for reverse transcriptase (RT) and the msr-msd region under a single promoter. A single RNA transcript from the msr-msd region serves not only as a template but also as a primer for...
