The widespread breakdown of dominant resistance genes, such as , due to the emergence of virulent races, like P6, has underscored the need for more durable, non-race-specific resistance.

Mimicking focused ultrasound with a loop coil in acoustic radiation force imaging.

Purpose: To enable development of MR-acoustic radiation force imaging (MR-ARFI) methods for targeting ultrasound in human subjects without the regulatory, acoustic, or hardware challenges associated with actual transcranial ultrasound setups.

Methods: MR-ARFI is a phase-contrast imaging method that measures focal tissue displacement produced by an ultrasound transducer, when the transducer is pulsed simultaneously with a motion encoding gradient. The ultrasound-induced focal phase shift can be mimicked with a small loop coil that is driven by a DC pulse to produce a resonance frequency offset at the same time as the ultrasound pulse in an MR-ARFI pulse sequence.

Non-contact diffuse reflectance spectroscopy using center-illuminated-area-detection modeled by a simple formula for assessing myoglobin.

A convenience that is desirable in diffuse reflectance spectroscopy (DRS) is to recover the spectral absorption by direct model inversion to facilitate decomposition of spectrally significant chromophores. Attaining such convenience that requires a simple forward model has been challenging in non-contact DRS, for assessing myoglobin forms, which is important to the evaluation of discoloration of meat. This work demonstrates that non-contact DRS configured in a center-illuminated-area-detection (CIAD) geometry [Appl.

Water-in-Fluorous Solvent Microemulsions: Media for (Bio)molecular Solvation.

Evidence for the formation of stable water pools within fluorous solvents (perfluorodecalin, perfluoromethylcyclohexane, and perfluorooctane) facilitated by a perfluorinated emulsifier perfluoroheptanoic acid (PFHA) under ambient conditions is presented. The presence of water-in-fluorous solvent (w/fluorous) microemulsions (MEs) is initially established with visual inspection and by constructing a pseudo-ternary phase diagram followed by dynamic light scattering (DLS), small-angle X-ray scattering (SAXS), and FTIR absorbance data analysis. DLS and SAXS measurements show that the hydrodynamic diameter () and radius of gyration () increase significantly with increase in water content.

Cases have highlighted GI complications caused by iron, predominantly involving the stomach and sometimes the esophagus.

Plasma extracellular cold inducible RNA-binding protein levels are elevated for 1 month post-colectomy which may promote metastases.

Background: Cold-inducible RNA-binding protein (CIRP) is related to a family of stress-induced RNA-binding proteins. It is primarily found in the nucleus, where it regulates transcription. Under stress, CIRP translocates to the cytoplasm where it modulates translation; a subset is secreted as extracellular CIRP (eCIRP) which is a damage-associated molecular pattern (DAMP) molecule that stimulates the production of inflammatory mediators.

Navigation strategies in Caenorhabditis elegans are differentially altered by learning.

Learned olfactory-guided navigation is a powerful platform for studying how a brain generates goal-directed behaviors. However, the quantitative changes that occur in sensorimotor transformations and the underlying neural circuit substrates to generate such learning-dependent navigation is still unclear. Here we investigate learned sensorimotor processing for navigation in the nematode Caenorhabditis elegans by measuring and modeling experience-dependent odor and salt chemotaxis.

Visible Light-Induced Energy Transfer Mediated Regioselective C-3 Thiolation of Imidazoheterocycles using Bunte Salts.

An external-photocatalyst-free visible light-induced regioselective C-3 sulfenylation of imidazo[1,2-a]pyridines using Bunte salts has been accomplished via C(sp)-H functionalization. This protocol allows the coupling of a wide range of imidazoheterocycles with alkyl-, benzyl-, and aryl Bunte salts under ambient air as the sole oxidant. The radical scavenging, UV-visible spectroscopic studies, and Stern-Volmer experiments revealed that the reaction occurs through energy transfer followed by a radical SET pathway.

Photoacid-Catalyzed Esterification of Carboxylic Acids Using Eosin Y.

A photoacid-catalyzed method for esterification is proposed wherein eosin Y is introduced as a photoacid and photoredox catalyst that can be activated with visible light and catalyze the esterification of carboxylic acids. The strategy presented here revealed that proton-coupled electron transfer (PCET) between eosin Y and carboxylic acid might facilitate the formation of a transient ketyl radical. This ketyl radical would subsequently undergo a single electron transfer and then couple with alkyl alcohols, yielding carboxylic esters in good to excellent yields.
