Research within the domain of spatial working memory has not conclusively determined whether age differences exist. Under some conditions, age-equivalence has been demonstrated for location information. Under other conditions, age-equivalence has been demonstrated for identity information. In three experiments, we examined identity memory, location memory, and their combination in a ...

Human exposure to polycyclic aromatic hydrocarbons (PAHs) can be assessed by biomonitoring of their urinary mono-hydroxylated metabolites (OH-PAHs). Limited information exists on the human pharmacokinetics of OH-PAHs. This study aimed to investigate the excretion half-life of 1-hydroxypyrene (1-PYR), the most used biomarker for PAH exposure, and 9 other OH-PAHs following ...

Extrusion technology has been employed successfully to improve the nutritive value of full fat oil seeds via the shear force and heat applied during passage through the extruder, exposing more peptide bonds to enzymatic hydrolysis. However, the fibrous portion of the seeds is largely intact following extrusion. Therefore, application of ...

Abstract We introduce a distinction between algorithm performance and algorithm competence and argue that bio-inspired computing should characterize the former rather than the latter. To exemplify this, we explore and extend a bio-inspired algorithm for collective construction influenced by paper wasp behavior. Despite its being provably general in its competence, ...

Ionization of ethylene, butadiene, hexatriene, octatetraene by short, intense laser pulses was simulated using the time dependent single-excitation configuration-interaction (TD-CIS) method and Klamroth's heuristic model for ionization (J. Chem. Phys. 2009, 131, 114304). The calculations used the 6-31G(d,p) basis set augmented with up to 3 sets of diffuse sp functions ...

OBJECTIVE:In 2011, the Accreditation Council on Graduate Medical Education increased restrictions on resident duty-hours. Additional changes have been considered, including greater work-hours restrictions and lengthening residency. Program directors tend to oppose further restrictions; however, residents' views are unclear. We sought to determine whether residents support these proposals, and if so ...

The so-called bias blind spot arises when people report that thinking biases are more prevalent in others than in themselves. Bias turns out to be relatively easy to recognize in the behaviors of others, but often difficult to detect in one's own judgments. Most previous research on the bias blind ...

(15)N-propargylcholine has been synthesized and hydrogenated with para-H(2). Through the application of a field cycling procedure, parahydrogen spin order is transferred to the 15N resonance. Among the different isomers formed upon hydrogenation of (15)N propargylcholine (1), only the non-transposed derivative contributes to the observed N-15 enhanced emission signal. Parahydrogen induced ...

L-ascorbate (L-ascorbic acid, vitamin C) clearly has an inhibitory effect on cancer cells. However, the mechanism underlying differential sensitivity of cancer cells from same tissue to L-ascorbate is yet to be clarified. Here, we demonstrate that L-ascorbate has a selective killing effect, which is influenced by sodium-dependent vitamin C transporter ...

Recently, we reported that a chimeric capsid protein assembled into a macromolecular container-like structure with capsid shell and the resulting siRNA/capsid nanocarrier complexes efficiently suppressed RFP gene expression in the cell culture system. To extend RNAi to the in vivo applications, we here demonstrated that the siRNA/capsid nanocarrier complexes could ...

A fluorescent aptamer sensor was applied to the analysis of extracellular chemical transmitter dynamics. We utilized a tocopherol-labeled aptamer, which allowed the direct anchoring of the fluorescent aptamer on the cell surface while retaining its performance as a fluorescent sensor. The fast-responsive fluorescent DNA aptamer sensor, which targets adenine compounds, ...

Accurate estimates of microbial synthesis in the rumen are vital to optimize ruminant nutrition. Liquid- (LAB) and solid-associated bacterial fractions (SAB) harvested from the rumen are generally considered as microbial references when microbial yield is calculated, however factors that determine their composition are not completely understood. The aim of this ...

Gambogic acid (1) is a cytotoxic caged xanthone derived from the resin of Garcinia hanburyi. Compound 1 selectively induces apoptosis in cancer cells, at least partially, by targeting the stress response to reactive oxygen species (ROS). However, the molecular mechanism of ROS toxicity stimulated by 1 remains poorly understood. In ...

We have developed a method to predict the hardness of materials containing ultrastrong anionic polyhedra, dense atomic clusters and layers stacked through Van der Waals bonds on the basis of group electronegativity. By considering these polyhedra, clusters and layers as groups which behave as rigid unities like superatoms bonding to ...

LASP-1 is a multidomain protein predominantly localized at focal contacts, where it regulates cytoskeleton dynamics and cell migration. However, in different tumor entities, a nuclear LASP-1 accumulation is observed, thought to have an important role in cancer progression. Until now, the molecular mechanisms that control LASP-1 nuclear import were not ...

Recent in vitro evidence indicates that astrocytes can modulate synaptic plasticity by releasing neuroactive substances (gliotransmitters). However, whether gliotransmitter release from astrocytes is necessary for higher brain function in vivo, particularly for memory, as well as the contribution of connexin (Cx) hemichannels to gliotransmitter release, remain elusive. Here, we microinfused ...
