Emerging roles of gap junction proteins connexins in cancer metastasis, chemoresistance and clinical application

Connexin, a four-pass transmembrane protein, contributes to assembly of gap junctions among neighboring cells and thus facilitates gap junctional intercellular communication (GJIC). Traditionally, the roles of connexins were thought to mediate formation of hemichannels and GJIC assembly for transportation of ions and small molecules. Many studies have observed loss of GJIC, due...

Effect of dynamic adjustment of diamond tools on nano-cutting behavior of single-crystal silicon

A new method for adjusting the tool rake and flank angles by changing the position of the tools was used to dynamic explore the nano-cutting behavior of single-crystal silicon using MD simulation. Simulations under the same cutting conditions were carried out using a tool swinging to six different rake angles of − 10°, − 15°, − 20°, − 25°, − 30°, − 35°, and − 45°. The advantages...

The Competition of Homophily and Popularity in Growing and Evolving Social Networks

Previous studies have used several models to investigate the mechanisms for growing and evolving real social networks. These models have been widely used to simulate large networks in many applications. In this paper, based on the evolutionary mechanisms of homophily and popularity, we propose a new generation model for growing and evolving social networks, namely, the Homophily...

Cytogenetic studies in three octopods, Octopus minor, Amphioctopus fangsiao, and Cistopus chinensis from the coast of China

To provide markers to identify chromosomes in the genome of octopods, chromosomes of three octopus species were subjected to NOR/C-banding. In addition, we examined their genome size (C value) to submit it to the Animal Genome Size Database. Silver staining revealed that the number of Ag-nucleoli was 2 (Octopus minor (Sasaki, 1920)), 2 (Amphioctopus fangsiao (d’Orbigny, 1839...

Material and Optical Properties of Fluorescent Carbon Quantum Dots Fabricated from Lemon Juice via Hydrothermal Reaction

The water-soluble fluorescent carbon quantum dots (CQDs) are synthesized by utilizing lemon juice as carbon resource via a simple hydrothermal reaction. The obtained CQDs are with an average size of 3.1 nm. They reveal uniform morphology and well-crystalline and can generate bright blue-green light emission under UV or blue light irradiation. We find that the fluorescence from...

Retraction Note: Association between serum vitamin D levels and the risk of kidney stone: evidence from a meta-analysis

The Editors are retracting this article [1] because post-publication peer review has identified multiple errors in the methodology of this meta-analysis, which invalidate the conclusions drawn.

Comparison of the genetic relationship between nine Cephalopod species based on cluster analysis of karyotype evolutionary distance

Karyotype analysis was carried out on gill cells of three species of octopods using a conventional air-drying method. The karyotype results showed that all the three species have the same diploid chromosome number, 2n=60, but with different karyograms as 2n=38M+6SM+8ST+8T, FN (fundamental number)=104 (Cistopus chinensis Zheng et al., 2012), 2n=42M+6SM+4ST+8T, FN=108 (Octopus...

Vehicle Detection Based on Deep Dual-Vehicle Deformable Part Models

Vehicle detection plays an important role in safe driving assistance technology. Due to the high accuracy and good efficiency, the deformable part model is widely used in the field of vehicle detection. At present, the problem related to reduction of false positivity rate of partially obscured vehicles is very challenging in vehicle detection technology based on machine vision...

Magneto-optical Kerr rotation and color in ultrathin lossy dielectric

Ultra-thin optical coating comprising nanometer-thick silicon absorbing films on iron substrates can display strong optical interference effects. A resonance peak of longitudinal Kerr rotation with the silicon thickness of was found at the wavelength of 660 nm. The optical properties of silicon thin films were well controlled by the sputtering power. Non-iridescence color...

A Method about the Propagation of Faults in Network

The study of network has been developed for several years. The research usually focuses on the attributes of the network, including the heterogeneity [1], the topology [2] [3] and the communities [4][5] of the network. About the propagation dynamics, reference [6][7] laid emphasis on the mathematical analysis of the propagation of networks. Although these researches are important...

Processing and targeting of proteins derived from polyprotein with 2A and LP4/2A as peptide linkers in a maize expression system

In the transformation of multiple genes, gene fusion is an attractive alternative to other methods, including sexual crossing, re-transformation, and co-transformation, among others. The 2A peptide from the foot-and-mouth disease virus (FMDV) causes the co-translational “cleavage” of polyprotein and operates in a wide variety of eukaryotic cells. LP4, a linker peptide that...
