Platelet Glycoprotein Ibα Is a Counterreceptor for the Leukocyte Integrin Mac-1 (Cd11b/Cd18)
The platelet counterreceptor is identified as glycoprotein (GP) Ibα, a component of the GP Ib-IX-V complex, the platelet von Willebrand factor (vWf) receptor, which provides a molecular target for disrupting leukocyte–platelet complexes that promote vascular inflammation in thrombosis, atherosclerosis, and angioplasty-related restenosis.

Artificial bacterial flagella: Fabrication and magnetic control
Inspired by the natural design of bacterial flagella, we report artificial bacterial flagella (ABF) that have a comparable shape and size to their organic counterparts and can swim in a controllableExpand
Rice SPX1 and SPX2 inhibit phosphate starvation responses through interacting with PHR2 in a phosphate-dependent manner
In vivo data, as well as results from in vitro experiments, showed that SPX1 and SPX2 inhibition of OsPHR2 activity is Pi-dependent, and these data provide evidence to support the involvement of SPX 1 andSPX2 in the Pi-sensing mechanism in plants. Expand
Does Tpeak-Tend provide an index of transmural dispersion of repolarization?
Tpeak-Tend is more valuable than QTc and QT dispersion as a predictor of TdP in patients with acquired LQTS and changes in this parameter are thought to be capable of reflecting changes in spatial dispersion of repolarization, particularly TDR, and thus may be prognostic of arrhythmic risk under a variety of conditions.

The heart of the H+ conductance mechanism in the homotetrameric M2 H+ channel from influenza A is a set of four histidine side chains. Here, we show that protonation of the third of these imidazolesExpand
Pipe-shaped BiCS flash memory with 16 stacked layers and multi-level-cell operation for ultra high density storage devices
We propose pipe-shaped bit cost scalable (P-BiCS) flash memory which consists of pipe-shaped NAND strings folded like a u-shape instead of the straight-shape. P-BiCS flash technology achieves aExpand
Applications of metal-organic frameworks in heterogeneous supramolecular catalysis.
This review summarizes the use of metal-organic frameworks (MOFs) as a versatile supramolecular platform to develop heterogeneous catalysts for a variety of organic reactions, especially forExpand

It is revealed that reactive hydrogen species are damaging to the formation of sp(2)-like SWNTs in a diameter-dependent manner, and the addition of oxygen scavenges H species and provides a powerful control over the C/H ratio to favor SWNT growth. Expand
FeO2 and FeOOH under deep lower-mantle conditions and Earth's oxygen-hydrogen cycles.
This process provides an alternative interpretation for the origin of seismic and geochemical anomalies in the deep lower mantle, as well as a sporadic O2 source for the Great Oxidation Event over two billion years ago that created the present oxygen-rich atmosphere. Expand
Sequence Analysis of Sarcosine Oxidase and Nearby Genes Reveals Homologies with Key Enzymes of Folate One-carbon Metabolism (*)
The results suggest that the α subunit and dimethylglycine dehydrogenase contain an NH2-terminal domain that binds noncovalent or covalent FAD, respectively, and a carboxyl- terminal H4folate-binding domain. Expand
