Agrobacterium vitis, the causal agent of grape crown gall, can have severe economic effects on grape production. The bacterium survives systemically in vines and therefore is disseminated in propagation material. We developed an assay, for use in indexing programs, that is efficient and sensitive for detecting A. vitis in grape ...

We demonstrate all-electrical spin injection, transport and detection in heavily n-type doped Si nanowires using ferromagnetic Co/Al(2)O(3) tunnel barrier contacts. Analysis of both local and non-local spin valve signals at 4 K on the same nanowire device using a standard spin-transport model suggests that high spin injection efficiency (up to ...

Electrostatic potential (ESP) is a useful physicochemical property of a molecule that provides insights into inter- and intra-molecular associations, as well as prediction of likely sites of electrophilic and nucleophilic metabolic attack. Knowledge of sites of metabolic attack is of parameter importance in DMPK research since drugs frequently fail in ...

ABSTRACT: BACKGROUND: Biological scientists have long sought after understanding how genes and their structural/functional changes contribute to morphological diversity. Though both grain (BTx623) and sweet (Keller) sorghum lines originated from the same species Sorghum bicolor L., they exhibit obvious phenotypic variations. However, the genome re-sequencing data revealed that they exhibited ...

The effect of cationic liposomes (CLs) on mRNA conformation and translation was studied, focusing on membrane heterogeneity. CLs, composed of 1,2-dioleoyl-sn-glycerol-3-phosphocholine/1,2-dioleoyl-3-timethylammonium propane (DOPC/DOTAP) and DOPC/3β-[N-(N',N'-dimethylaminoethane)-carbamoyl]cholesterol (DOPC/DC-Ch), inhibited mRNA translation in an Escherichia coli cell-free translation system. Analysis of the membrane fluidity and polarity indicated a heterogeneous DOPC/DC-Ch (70/30) membrane, while ...

ABSTRACT: BACKGROUND: The hallmark of atherosclerosis is the accumulation of plaque in vessel walls. This process is initiated when monocytic cells differentiate into macrophage foam cells under conditions with high levels of atherogenic lipoproteins. Vulnerable plaque can dislodge, enter the blood stream, and result in acute myocardial infarction and stroke. ...

Tissue factor (TF) by forming a complex with factor VIIa (FVIIa) initiates blood coagulation. It was traditionally believed that the separation of FVIIa in circulation from subendothelial TF was the main control that was preventing spontaneous initiation of thrombosis and that circulating cells and endothelium did not express TF protein ...

ABSTRACT: BACKGROUND: Negation occurs frequently in scientific literature, especially in biomedical literature. It has previously been reported that around 13% of sentences found in biomedical research articles contain negation. Historically, the main motivation for identifying negated events has been to ensure their exclusion from lists of extracted interactions. However, recently, ...

Background Expert surgeons use a mass of intra-operative information, as well as pre- and post-operative information to complete operations safely. Trainees acquired this intra-operative knowledge at the operating table, now largely diminished by the working time directive. Wikis offer unexplored approaches to capturing and disseminating expert knowledge to further promote ...

An artificial polydimethylsiloxane/polyphenylsulfone (PDMS/PPSU) membrane, which emulates the hydrophobic behavior of natural membranes was synthesized. Hydrophobicity was achieved by coating the membrane surface sublayer using conventional silicon material, which imitates the character of epicuticular wax (EW) of Prunus laurocerasus L. leaves. It was then applied as a separation medium in ...

The second near-infrared window (NIR-II, wavelength of 1.0-1.4 μm) is optimal for the bioimaging of live animals due to their low albedo and endogenous autofluorescence. Herein, we report a facile and one-pot biomimetic synthesis approach to prepare water-dispersible NIR-II-emitting ultrasmall Ag(2)S quantum dots (QDs). Photoluminescence spectra showed that the emission peaks ...

ABSTRACT: BACKGROUND: The glycoprotein MFG-E8 mediates phagocytic clearance of apoptotic cells and influences the pathogenesis and progression of inflammatory diseases. MFG-E8 was shown to attenuate the progression of inflammation and to improve survival in septic rats. Accumulating evidence suggests an immunomodulatory link between MFG-E8 and the pro-inflammatory chemokine fractalkine, which ...
