Recent studies have revealed that rottlerin is a natural chemical drug to exert its anti-cancer activity. However, the molecular mechanisms of rottlerin-induced tumor suppressive function have not been fully elucidated. Notch signaling pathway has been characterized to play a crucial role in tumorigenesis. Therefore, regulation of Notch pathway could be beneficial for the treatment of human cancer. The aims of our current study were to explore whether rottlerin could suppress Notch-1 expression, which leads to inhibition of cell proliferation, migration and invasion in nasopharyngeal carcinoma cells...

HOXA11 antisense RNA (HOXA11-AS) has been shown to be involved in tumorigenesis and development of different cancers. However, the role of HOXA11-AS in non-small cell lung cancer (NSCLC) remains unclear. In this study, we firstly explored and confirmed the expression of HOXA11-AS in NSCLC tissues and cells. Cytometry, CCK-8, cell scratch, migration, Matrigel invasion and flow cytometry assays were performed to determine the biological impact of HOXA11-AS in vitro. Furthermore, a chick embryo chorioallantoic membrane (CAM) model of NSCLC was constructed to explore the effect of HOXA11-AS on tumorigenicity and angiogenesis in vivo...

Chronic hyperglycemia is a potent risk factor of abnormal angiogenesis with various tissue diseases. Autophagy, as an alternative cell response, is mostly generated by a vast array of insults. Applying autophagic response contributes to normal cell retrieval circumstance during various insults. We aimed to show whether stimulation/inhibition of autophagy could reduce or exacerbate oxidative status and angiogenic potential in endothelial cells after exposure to 30mM glucose. HUVECs were incubated with the combined regime of 100nM Rapamycin and 30mM glucose over a period of 72h...

OBJECTIVE: This study explored the ability of microRNA-135a (miR-135a) to influence cell proliferation, migration, invasion, apoptosis and tumor angiogenesis through the IGF-1/PI3K/Akt signaling pathway in non-small cell lung cancer (NSCLC). METHODS: NSCLC tissues and adjacent normal tissues were collected from 138 NSCLC patients. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression levels of miR-135a and IGF-1, PI3K, Akt, VEGF, bFGF and IL-8 mRNA; western blotting was used to determine the expression levels of IGF-1, PI3K and Akt protein; and enzyme-linked immunosorbent assay (ELISA) was used to analyze the expression levels of VEGF, bFGF and IL-8 protein...

BACKGROUND: The application of computer-aided design computer-aided manufacturing (CAD CAM) technology in the fabrication of complete dentures, offers numerous advantages as it provides optimum fit and eliminates polymerization shrinkage of the acrylic base. Additionally, the porosity and surface roughness of CAD CAM resins is less compared to conventionally processed resins which leads to a decrease in the adhesion of bacteria on the denture base, which is associated with many conditions including halitosis and aspiration pneumonia in elderly denture wearers...

BACKGROUND: Recent studies have revealed that microRNAs (miRNAs) play important roles as oncogenes or tumor suppressors in tumorigenesis and tumor development, by negatively regulating protein expression. A previous study of microarrays identified that miR-411 was down-regulated in renal cell carcinoma (RCC), while few studies investigating the role of miR-411 in the pathogenesis of RCC have been performed. METHODS: We assessed the miR-411 expression in RCC and paired adjacent normal tissues, as well as in RCC cell lines and a normal renal cell line, by quantitative reverse transcriptase polymerase chain reaction (qRT-PCR)...

Cat scratch disease (CSD) is a zoonotic infection caused primarily by the bacterium Bartonella henselae. An estimated 12,000 outpatients and 500 inpatients are diagnosed with CSD annually, yet little is known regarding clinician experience with and treatment of CSD in the United States. Questions assessing clinical burden, treatment and prevention of CSD were posed to 3,011 primary care providers (family practitioners, internists, paediatricians and nurse practitioners) during 2014-2015 as part of the annual nationwide DocStyles survey...

INTRODUCTION: Intense nocturnal pruritus as well as the complex pathophysiology of atopic dermatitis (AD) can severely affect sleep and become a major factor in negatively impacting quality of life in adults. However, much of the literature on sleep disturbance in AD patients is on the pediatric population, and it is not well studied in adults. Furthermore, limited studies are available to guide effective management of sleep disturbance in AD in general. We review the literature to present the studies that have investigated the relationship between AD and its effect on sleep in adults and provide an approach for clinicians caring for this population...

Liljencrantz et al report the failure of observing contagious itch behavior using mice injected with histamine as the demonstrators. Analysis of their results shows that the histamine model is limited by inadequate frequency and duration of scratching bouts required for contagious itch test. To streamline the contagious itch test, the screen paradigm is highly recommended.

Yu et al (Reports, 10 March 2017, p. 1072) state that contagious itch occurs in mice based on imitative scratching in normal mice observing excessive scratching in genetically modified demonstrator mice. However, despite employing multiple behavioral analysis approaches, we were unable to extend these findings to normal mice observing the well-established histamine model of acute itch in demonstrator mice.

OBJECTIVE: Similar to cancer, pulmonary arterial hypertension (PAH) is characterized by vascular remodeling, which leads to obliteration of the small pulmonary arteriole, with marked proliferation of pulmonary artery smooth muscle cells (PASMC) and/or endothelial cells dysfunction. Aberrant expression of tumor suppressor genes is closely associated with susceptibility to PAH. We hypothesized that α-solanine, a glycoalkaloid found in members of the nightshade family known to have antitumor activity in different cancers, reverses experimental PAH by activating the tumor suppressor-axis inhibition protein 2 (AXIN2)...

Itch, a sensation eliciting a desire to scratch, is distinct from but not completely independent of pain. Inspiring achievements have been made in the characterization of itch-related receptors and neurotransmitters, but the molecular mechanisms controlling the development of pruriceptors remain poorly understood. Here, our RNAseq and in situ hybridization data show that the transcription factor Tlx3 is required for the expression of a majority of itch-related molecules in the dorsal root ganglion (DRG). As a result, Tlx3(F/F);Nav1...

OBJECTIVES: Medication-related osteonecrosis of the jaws (MRONJ) is an extremely therapy-resistant disease involving the jaws especially following bisphosphonate treatment. Bisphosphonates accumulate in bone in concentrations sufficient to be directly toxic to the oral epithelium. Current therapeutic options are inadequate for the prevention and treatment of MRONJ. The aim of this study was to investigate effects of ozone gas plasma therapy on wound healing in bisphosphonate-applied human fibroblasts...

Anthony B Wilson
The adaptive immune system has long been considered a key evolutionary innovation of the vertebrates, the product of two rounds of genome duplication that gave rise to the raw material necessary for the evolution of a highly specific immune response and immune memory. While comparative studies of a small number of model organisms have led to the commonly held view that the adaptive immune system has remained relatively static since its origin, recent studies of non-model organisms are challenging this notion, highlighting the fact that we have only begun to scratch the surface in terms of our understanding of immune system diversity...

Human epidermal growth factor (hEGF) plays important roles in wound healing. Due to large molecular weight and hydrophilic nature, cellular uptake and skin permeation of hEGF are very poor, significantly limiting its efficacy. By using recombinant technology, four structural classes of cell penetrating peptides (CPPs) were fused at the C-terminus of hEGF, expressed and purified into homogeneity. Comparative studies were conducted to evaluate their activity, cytotoxicity, cellular uptake and skin permeation...

We present a simple and effective architecture for fine-grained recognition called Bilinear Convolutional Neural Networks (B-CNNs). These networks represent an image as a pooled outer product of features derived from two CNNs and capture localized feature interactions in a translationally invariant manner. B-CNNs are related to orderless texture representations built on deep features but can be trained in an end-to-end manner. Our most accurate model obtains 84.1%, 79.4%, 84.5% and 91.3% per-image accuracy on the Caltech-UCSD birds [66], NABirds [63], FGVC aircraft [42], and Stanford cars [33] dataset respectively and runs at 30 frames-per-second on a NVIDIA Titan X GPU...
