Coseismic displacement estimate of the 2013 M S7.0 Lushan, China earthquake based on the simulation of near-fault displacement field

Usually, GPS observation provides direct evidence to estimate coseismic displacement. However, GPS stations are scattered, sparse and cannot provide a detailed distribution of coseismic displacement. Strong ground motion records share the same disadvantages as GPS in estimating coseismic displacement. Estimations from InSAR data can provide displacement distributions; however...

A new insight into male fertility preservation for patients with completely immotile spermatozoa

Sperm cryopreservation is the most effective method to preserve male fertility but this is normally used for motile spermatozoa. Thus, only motile spermatozoa are used for cryopreservation in most reproductive medicine centers worldwide. The immotile spermatozoa from some problematic patients are usually discarded, resulting in a missed opportunity of sterility cryopreservation...

Genetic polymorphism rs3760396 of the chemokine (C-C motif) ligand 2 gene (CCL2) associated with the susceptibility of lung cancer in a pathological subtype-specific manner in Han-ancestry Chinese: a case control study

Background Chemokines are well known inflammatory factors critical for tumor development in diverse tissues, including lung cancer. Chemokine (C-C motif) Ligand 2 (CCL2) was one of such chemokines important for both primary tumor development and metastasis of various cancers. Polymorphism at rs3760396 of CCL2 genes is associated with the prognosis of non-small cell lung cancer...

Analysis of charmless two-body B decays in factorization-assisted topological-amplitude approach

We analyze charmless two-body non-leptonic B decays \(B \rightarrow PP, PV\) under the framework of a factorization-assisted topological-amplitude approach, where P(V) denotes a light pseudoscalar (vector) meson. Compared with the conventional flavor diagram approach, we consider the flavor SU(3) breaking effect assisted by a factorization hypothesis for topological diagram...

Coblation tonsillectomy under surgical microscopy: A retrospective study

Objective A retrospective study to compare surgical parameters and postoperative pain in patients undergoing coblation tonsillectomy with or without microscopic guidance.

READ-ONLY OBJECT IN OBJECT-ORIENTED PROGRAMMING

Object-oriented programming (OOP) has become the dominant programming paradigm by its promise of easy code maintenance, code reuse, and code evolution. The central dogma in OOP is to model a concept as an object that has its own internal state and behavior. How to limit the access to the internal state of an object is always a tricky question to new OOP programmers. Though OOP...

High throughput deep degradome sequencing reveals microRNAs and their targets in response to drought stress in mulberry (Morus alba)

MicroRNAs (miRNAs) play important regulatory roles by targeting mRNAs for cleavage or translational repression. Identification of miRNA targets is essential to better understanding the roles of miRNAs. miRNA targets have not been well characterized in mulberry (Morus alba). To anatomize miRNA guided gene regulation under drought stress, transcriptome-wide high throughput...

The up-regulation of Myb may help mediate EGCG inhibition effect on mouse lung adenocarcinoma

Background Green tea polyphenol epigallocatechin-3-gallate (EGCG) has been demonstrated to inhibit cancer in experimental studies through its antioxidant activity and modulations on cellular functions by binding specific proteins. By means of computational analysis and functional genomic approaches, we previously identified a set of protein coding genes and microRNAs whose...

Child feeding and stunting prevalence in left-behind children: a descriptive analysis of data from a central and western Chinese population

Objectives To examine the effect of parental rural-to-urban internal migration on nutritional status of left-behind children and how this is related to guardianship. Methods We used UNICEF China’s maternal and child health survey data to investigate stunting prevalence and feeding practices in children left behind by rural-to-urban internal migrant parents. We also assessed the...

Overexpression of Ribosomal RNA in the Development of Human Cervical Cancer Is Associated with rDNA Promoter Hypomethylation

The ribosomal RNA (rRNA) gene encodes rRNA for protein synthesis. Aberrant expression of the rRNA gene has been generally observed in tumor cells and levels of its promoter methylation as an epigenetic regulator affect rRNA gene transcription. The possible relationship between expression and promoter methylation of rDNA has not been examined in human clinical cervical cancer...

High Efficiency, Low Power-Consumption DFB Quantum Cascade Lasers Without Lateral Regrowth

Very low power-consumption distributed feedback (DFB) quantum cascade lasers (QCLs) at the wavelength around 4.9 μm were fabricated by conventional process without lateral regrowth of InP:Fe or using sidewall grating. Benefitted from the optimized materials and low waveguide loss, very low threshold current density of 0.5 kA/cm2 was obtained for a device with cavity length of 2...

A power-efficient synchronization scheme for the MB-OFDM-based UWB systems

Due to the complexity of multi-band orthogonal frequency-division multiplexing (MB-OFDM), achieving low power is still one of the major difficulties in designing the MB-OFDM-based ultra wideband (UWB) receiver. This paper targets at providing a very low power synchronization scheme with high performance for the MB-OFDM UWB receiver. First, the power consumptions of the individual...

A putative ATPase mediates RNA transcription and capping in a dsRNA virus

mRNA transcription in dsRNA viruses is a highly regulated process but the mechanism of this regulation is not known. Here, by nucleoside triphosphatase (NTPase) assay and comparisons of six high-resolution (2.9–3.1 Å) cryo-electron microscopy structures of cytoplasmic polyhedrosis virus with bound ligands, we show that the large sub-domain of the guanylyltransferase (GTase...

Altered regulation and expression of genes by BET family of proteins in COPD patients

Background BET proteins (BRD2, BRD3, BRDT and BRD4) belong to the family of bromodomain containing proteins, which form a class of transcriptional co-regulators. BET proteins bind to acetylated lysine residues in the histones of nucleosomal chromatin and function either as co-activators or co-repressors of gene expression. An imbalance between HAT and HDAC activities resulting in...
