The precise regulation of synaptic growth is critical for the proper formation and plasticity of functional neural circuits. Identification and characterization of factors that regulate synaptic growth and function have been under intensive investigation. Here we report that brain tumor (brat), which was identified as a translational repressor in multiple(More)
In a broad range of taxa, genes can duplicate through an RNA intermediate in a process mediated by retrotransposons (retroposition). In mammals, L1 retrotransposons drive retroposition, but the elements responsible for retroposition in other animals have yet to be identified. Here, we examined young retrocopies from various animals that still retain the(More)
In this paper, an ultra-wideband and polarization-independent metasurface for radar cross section (RCS) reduction is proposed. The unit cell of the metasurface operates in a linear cross-polarization scheme in a broad band. The phase and amplitude of cross-polarized reflection can be separately controlled by its geometry and rotation angle. Based on the(More)
Circular RNAs (circRNAs) are a class of endogendous RNAs that form a covalently closed continuous loop and exist extensively in mammalian cells. Majority of circRNAs are conserved across species and often show tissue/developmental stage-specific expression. CircRNAs were first thought to be the result of splicing error; however, subsequent research shows(More)
BACKGROUND Jellyfish envenomation is common along the coastal area, and can cause severe consequences. Naval personnel are among the high-risk population for this injury. The aim of this study was to assess knowledge regarding jellyfish envenomation among naval personnel in a navy unit in northeast China. METHODS A predesigned questionnaire was(More)
OBJECTIVES Accidental hypothermia (AH) is a potentially life-threatening condition that can lead to significant morbidity and life-long effects. Navy personnel are always at a greater risk of AH due to frequent outdoor work, wilderness exposure, prolonged immobility and exhaustion. The purpose of the survey was to assess Chinese Navy members' awareness of(More)
It is known that evolutionarily new genes can rapidly evolve essential roles in fundamental biological processes. Nevertheless, the underlying molecular mechanism of how they acquire their novel transcriptional pattern is less characterized except for the role of cis-regulatory evolution. Epigenetic modification offers an alternative possibility. Here, we(More)
Several mitochondrial tRNA mutations have been associated with hypertension, but their pathophysiology remains poorly understood. In this report, we identified a novel homoplasmic 3253T→C mutation in the mitochondrial tRNALeu(UUR) gene in a Han Chinese family with maternally inherited hypertension. The m.3253T→C mutation affected a highly conserved uridine(More)
Nanoparticles based on chitosan hydrochloride (CSH)-hyaluronic acid (HA)-PEG were prepared for delivering curcumin (CUR) (CUR-PNPs) to brain tumor. CUR-PNPs of 245.9nm and spherical morphology were obtained at optimized CSH/HA/PEG20000/CUR ratios with negative charge of about -27.2mV and EE of approximately 93.3%. Cytotoxicity studies showed that CUR-PNPs(More)
Many databases and platforms for human brain data have been established in China over the years, and metadata plays an important role in understanding and using them. The BrainBank Metadata Specification for the Human Brain Project and Neuroinformatics provides a structure for describing the context and content information of BrainBank databases and(More)
