Precise regulation of synapses during development is essential to ensure accurate neural connectivity and function of nervous system. Many signaling pathways, including the mTOR (mechanical Target of Rapamycin) pathway operate in neurons to maintain genetically determined number of synapses during development. mTOR, a kinase, is shared between two functionally distinct multi-protein complexes- ...

The electromagnetic wave time reversal technology using cavity (TRC) has potential applications in many areas, such as pulse compression, power synthesis, perturbation detection, beamforming, etc. Microwave chaotic with multi-path transmission characteristics is usually used TRC. Based on diffraction theory, it can prove that this kind of spatiotemporal focusing and be for compressing pulses, b...

The aim of this study was to evaluate the performance of the transcription-reverse transcription concerted (TRC) method for the detection of Mycobacterium tuberculosis complex (MTC) 16S rRNA in clinical respiratory samples for the diagnosis of pulmonary tuberculosis. TRC is a novel method that enables the rapid and the completely homogeneous real-time monitoring of isothermal sequence RNA ampli...

BACKGROUND Real-time quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) for detection of carcinoembryonic antigen (CEA) mRNA in the peritoneal lavage of gastric cancer patients is now recognized as a useful method for the prediction of peritoneal recurrence after curative surgery. One problem with this method is that it is time-consuming and difficult to perform an intraoper...

The rapid and accurate diagnosis of tuberculosis is crucial to providing optimal treatment and reducing the spread of infection. We evaluated respiratory and nonrespiratory clinical specimens using a new automated Mycobacterium tuberculosis complex (MTBC) rRNA detection kit (TRCRapid M.TB; Tosoh Bioscience, Tokyo, Japan), which is based on the transcription-reverse transcription concerted react...

To cover the receptive field completely but without redundancy, neurons of certain functional groups exhibit tiling of their dendrites via dendritic repulsion. Here we show that two evolutionarily conserved proteins, the Tricornered (Trc) kinase and Furry (Fry), are essential for tiling and branching control of Drosophila sensory neuron dendrites. Dendrites of fry and trc mutants display excess...

Currently, Canada is in a post-TRC moment: the 2015 TRC or Truth and Reconciliation Commission report marks breakpoint history of its intercultural relationships at national scale, and...

Abstract Biomechanics is a fundamental feature of cell. However, the manner by which actomysin tension affects tumor immune evasion remains unclear. Here we show that although cytotoxic T lymphocytes (CTL) can effectively destroy stiff differentiated cells, they fail to kill soft tumor-repopulating cells (TRC). TRC softness prevented membrane pore formation caused CTL-released perforin. Perfori...

To cover the receptive field completely and non-redundantly, neurons of certain functional groups arrange tiling of their dendrites. In Drosophila class IV dendrite arborization (da) neurons, the NDR family kinase Tricornered (Trc) is required for homotypic repulsion of dendrites that facilitates dendritic tiling. We here report that Sin1, Rictor, and target of rapamycin (TOR), components of th...
