In this study, we compared their toxicity in vivo and in vitro based on the physicochemical properties of three different types of TiO(2) nanowires, H(2)Ti(3)O(7) nanowires (1HTO), hydrothermal treatment (2HTO), and calcination (3HTO) of 1HTO. The surface of 1HTO was smooth, and the surface of 2HTO was much rougher. The ...

The assessment of cerebrovascular regulatory mechanisms often requires flexibly controlled and precisely timed changes in arterial blood pressure (ABP) and/or inspired CO(2). In this study, a new system for inducing variations in mean ABP was designed, implemented and tested using programmable sequences and programmable controls to induce pressure changes through ...

Triticale is being considered as a bioindustrial crop in Canada using genetic modification. Because related spring wheat (Triticum aestivum) and durum wheat (T. durum) may exhibit synchronous flowering and grow in proximity, determination of interspecific gene flow when triticale is the pollen donor is necessary to evaluate potential risk. Pollen-mediated ...

Changes in synaptic efficacy and morphology are considered as the downstream mechanisms of consolidation of memories and other adaptive behaviors. In the last decade, neurotrophin-3 (NT-3) has emerged as one potent mediator of synaptic plasticity. In the adult brain, expression of NT-3 is largely confined to the hippocampal dentate gyrus ...

ABSTRACT Background: In mild Alzheimer's disease (AD), a deficit in episodic memory, particularly autobiographical memory, is clearly established. Several recent studies have also shown impaired semantic memory from the onset of the disease. Musical memory capacities may be especially preserved and listening to music might encourage autobiographical recall. The aim ...

Research on retrieval suppression has produced varying results concerning whether negatively valenced memories are more or less suppressible than neutral memories. This variability may arise if, across studies, participants adopt different approaches to memory control. Cognitive and neurobiological research points to two mechanisms that achieve retrieval suppression: thought-substitution and direct ...

SUMMARY We have previously shown that the subunit 1 of Leishmania amazonensis RPA (LaRPA-1) alone binds the G-rich telomeric strand and is structurally different from other RPA-1. It is analogous to telomere end-binding proteins described in model eukaryotes whose homologues were not identified in the protozoan´s genome. Here we show ...

The spontaneous microaggregation of platelets (SMAPs) is a marker for the prognosis of patients with cardiovascular diseases. Coupling factor 6 (CF6) binds to the plasma membrane ATP synthase and functions as a pro-atherogenic molecule in the cardiovascular system. However, the role of CF6 in SMAPs and stroke remains unknown. In ...

We previously reported that plasmacytoid dendritic cells (pDC) infiltrating breast tumors are impaired for their IFN-α production, resulting in local Treg amplification. We designed the present study to decipher molecular mechanisms of such functional defect of tumor-associated pDC (TApDC) in breast cancer. We demonstrate that besides IFN-α, the production by ...

AlCl(3) promoted Friedel-Crafts acylation between 4-tert-butylbenzoyl chloride and mesitylene was investigated. The donor-acceptor complex was observed as the major species. Kinetic investigation demonstrated that the reaction was first-order on the donor-acceptor complex and zero-order on ArH, suggesting that the donor-acceptor complex was not the true reactive species. However, the acylium ...

The functionalist memory perspective predicts that information of adaptive value may trigger specific processing modes. It was recently demonstrated that women's memory is sensitive to cues of male sexual dimorphism (i.e., masculinity) that convey information of adaptive value for mate choice because they signal health and genetic quality, as well ...

Neuronal N-methyl-D-aspartate receptors (NMDARs) play a critical role in synaptic plasticity. Their activation requires not only binding of their ligand glutamate and membrane depolarization but also the presence of a co-agonist, glycine or D-serine. An increasing body of experimental evidence suggests that different populations of NMDARs could be gated by ...
