BACKGROUND This study aimed to explore the correlation between FGFR1 and clinical features, including survival analysis and the promotion of angiogenesis by fibroblast growth factor receptor 1 (FGFR1) and vascular endothelial growth factor receptor 2 (VEGFR2). FGFR1 gene amplification has been found in non-small cell lung cancer (NSCLC). However, the prognostic value of FGFR1 and the correlation between FGFR1 and clinical features are still controversial. MATERIAL AND METHODS A total of 92 patients with NSCLC who underwent R0 resection between July 2006 and July 2008 were enrolled in the study...

Last generation of force-fields are raising expectations on the quality of molecular dynamics (MD) simulations of DNA, as well as to the belief that theoretical models can substitute experimental ones in several cases. However these claims are based on limited benchmarks, where MD simulations have shown the ability to reproduce already existing 'experimental models', which in turn, have an unclear accuracy to represent DNA conformation in solution. In this work we explore the ability of different force-fields to predict the structure of two new B-DNA dodecamers, determined herein by means of (1)H nuclear magnetic resonance (NMR)...

Space radiation and microgravity are recognized as primary and inevitable risk factors for humans traveling in space, but the reports regarding their synergistic effects remain inconclusive and vary across studies due to differences in the environmental conditions and intrinsic biological sensitivity. Thus, we studied the synergistic effects on transcriptional changes in the global genome and DNA damage response (DDR) by using dys-1 mutant and ced-1 mutant of C. elegans, which respectively presented microgravity-insensitivity and radiosensitivity when exposure to spaceflight condition (SF) and space radiation (SR)...

Normal sexual differentiation in the genital organs is essential for the animal species that use sexual reproduction. Although it is known that doublesex (dsx) is required for the sexual development of the genitalia in various insect species, the direct target genes responsible for the sexual differentiation of the genitalia have not been identified. The lozenge (lz) gene is expressed in the female genital disc and is essential for developments of spermathecae and accessory glands in Drosophila melanogaster...

The success of rituximab for the treatment of active Graves' orbitopathy (GO) suggests that B cells play a critical role in intraorbital inflammation. B cell activating factor (BAFF) and its homolog a proliferation-inducing ligand (APRIL) are critical for B cell survival. However, the contribution of BAFF/APRIL to GO remains unclear. We sought to determine the role of BAFF/APRIL in the orbits of GO, and found that BAFF was markedly upregulated, while APRIL was not. Additionally, cultured GO orbital fibroblasts (GO-OFs)(2) expressing BAFF were induced to produce a large amount of BAFF...

Lu Zhang, Fang Dai, LiuQing Cui, Bo Zhou, YuQi Guo
The importance of macroautophagy (hereafter referred to as autophagy) in vascular endothelial cell (VEC) biology and dysfunction is increasingly recognized, but the molecular mechanisms of autophagy in VECs in the presence of serum are still poorly understood. Previously, we identified pterostilbene as a potent autophagy inducer of VECs in the presence of serum. In this study, we used pterostilbene as a tool to induce VEC autophagy and identified the differentially expressed genes using high-throughput DAN microarray...

BACKGROUND: Around 30% of the population will experience herpes zoster (HZ), 10% of whom develop postherpetic neuralgia (PHN). Together, these illnesses produce a significant economic burden to the healthcare system. METHODS: Administrative healthcare data collected over the period of April 1(st) 1997 to March 31(st) 2014 were analyzed to determine the healthcare system burden of HZ using direct medical costs. Episodes of HZ were identified using international classification of disease (ICD) codes...

Since Dan Olweus's seminal work on bullying in the 1970's (Olweus, 1978), there has been a concerted effort by investigators to identify the confluence of factors that contribute to peer victimization and its role in psychosocial development. Although the cause and consequences of peer victimization may include underlying, age-invariant processes, the manifestation of these factors is, in part, driven by the developmental stage being studied. Thus, a comprehensive understanding of peer victimization requires an explicit developmental perspective...

The North American beaver (Castor canadensis) is a managed species in the United States. In northern Wisconsin, as part of the state-wide beaver management program, the Chequamegon-Nicolet National Forest removes beavers from targeted trout streams on U.S. Forest Service lands. However, the success of this management program has not been evaluated. Targeted removals comprise only 3% of the annual beaver harvest, a level of effort that may not affect the beaver population. We used colony location data along Forest streams from 1987-2013 (Nicolet, northeast Wisconsin) and 1997-2013 (Chequamegon, northwest Wisconsin) to assess trends in beaver colony density on targeted trout streams compared to non-targeted streams...

Despite widespread uses of tetanus toxoid (TT) as a vaccine, model antigen and protein carrier, TT epitopes have been poorly characterized. Herein we defined the human CD4+ T cell epitope repertoire by reevaluation of previously described epitopes and evaluation of those derived from prediction of HLA Class II binding. Forty-seven epitopes were identified following in vitro TT stimulation, with 28 epitopes accounting for 90% of the total response. Despite this diverse range of epitopes, individual responses were associated with only a few immunodominant epitopes, with each donor responding on average to 3 epitopes...

Amino naphthalene 2-Cyanoacrylate (ANCA) probe is a kind of fluorescent amyloid binding probe that can report a different fluorescence emission when bound to different types of amyloid deposits in tissue, while their interactions with amyloid fibrils remain unclear due to the insoluble nature of amyloid fibrils. Here, all atom molecular dynamics simulations were used to investigate the interaction between ANCA probes with three different amyloid fibrils. Two common binding modes of ANCA probes on Aβ40 amyloid fibrils were identified by cluster analysis of multiple simulations...

Metal meshes have emerged as an important class of flexible transparent electrodes. We report on the characteristics of a new class of asymmetric meshes, tiled using a recently-discovered family of pentagons. Micron-scale meshes were fabricated on flexible polyethylene terephthalate substrates via optical lithography, metal evaporation (Ti 10 nm, Pt 50 nm) and lift-off. Three different designs were assessed, each with the same tessellation pattern and linewidth (5 µm), but with different sizes of the fundamental pentagonal unit...

DNA-based machines have attracted rapidly growing interest owing to their potential in drug delivery, biocomputing, and diagnostic applications. Herein, we report a type of exonuclease III (Exo III)-powered stochastic DNA walker that can autonomously move on a spherical nucleic acid (SNA)-based 3D track. The motion is propelled by unidirectional Exo III digestion of hybridized DNA tracks in a burnt-bridge mechanism. The operation of this Exo III-propelled DNA walker was monitored in real time and at the single-particle resolution using total internal reflection fluorescence microscopy (TIRF)...
