Metastasis to regional lymph nodes (RLNs) in dogs with cutaneous mast cell tumour (cMCT) has been correlated with shortened survival time and higher risk of spread to distant sites. In the present study, extirpation of non-palpable or normal-sized RLNs was included in the surgical management of cMCT in dogs. Correlations between histological nodal status (HN0-3) and tumour variables were analysed. Ninety-three dogs with single cMCT without distant metastasis that underwent wide surgical excision of the primary tumour and extirpation of non-palpable or normal-sized RLN were included...

Here we describe a novel (-)ssRNA mycovirus, Fusarium graminearum negative-stranded RNA virus 1 (FgNSRV-1), isolated from Fusarium graminearum strain HN1. The genome of FgNSRV-1 is 9072 nucleotides in length, with five discontinuous but linear ORFs (ORF I-V). Phylogenetic analysis based on entire L polymerase sequences indicated that FgNSRV-1 is related to the (-)ssRNA mycovirus Sclerotinia sclerotiorum negative-stranded RNA virus 1 (SsNSRV-1), and other mycoviruses. Our data suggest that FgNSRV-1 can be classified into the family Mymonaviridae, order Mononegavirales...

BACKGROUND: Vascular cognitive impairment with no dementia (VCIND), manifested mainly as mild impairment of concentration and executive function, is the early phase of vascular dementia (VD). Currently, there is no specific treatment for VCIND. We hypothesize that electrical acupuncture can improve the mental and motor functions of patients with VCIND. Thus, we designed this randomized controlled trial to test this hypothesis by comparing the therapeutic effect of electrical acupuncture versus sham acupuncture in patients with VCIND...

Autism is considered as a complex developmental disability that appears during the first two years of life. It is considered as a neurological disorder that affects brain function leading to impaired development in social interaction and communication skills. Some clinical trials demonstrated that certain acupuncture points play relatively significant role in improving both signs and symptoms of this disease. Owing to limited information available about acupuncture point's combination and protocols, the present study aimed to explore the most frequently used acupuncture points and their channels for children with autism...

The clinical manifestation and clinical diagnosis and treatment of acupuncture for persistent somatoform pain disorder (PSPD) were observed to explore its etiology. It is found that the causative factor of PSPD is probably relevant with pain memory induced by the negative emotions during the first attack of pain, which is in the category of "depression" in TCM. In clinical diagnosis, the medical history should be explored to discover the potential etiology and determine the diagnosis. In treatment, the root cause should be considered, focusing on mind and qi regulation and associating with analgesia...

BACKGROUND: Lung fibroblasts are involved in extracellular matrix homeostasis, which is mainly regulated by transforming growth factor-beta (TGF-β), and are therefore crucial in lung tissue repair and remodeling. Abnormal repair and remodeling has been observed in lung diseases like COPD. As miRNA levels can be influenced by TGF-β, we hypothesized that TGF-β influences miRNA expression in lung fibroblasts, thereby affecting their function. MATERIALS AND METHODS: We investigated TGF-β1-induced miRNA expression changes in 9 control primary parenchymal lung fibroblasts using miRNA arrays...

Epstein-Barr virus (EBV) is a ubiquitous gammaherpesvirus that is highly prevalent in almost all human populations and is associated with many human cancers, such as nasopharyngeal carcinoma (NPC), Hodgkin's disease, and gastric carcinoma. However, in these EBV-associated cancers, only NPC exhibits remarkable ethnic and geographic distribution. We hypothesized that EBV genomic variations might contribute to the pathogenesis of different human cancers in different geographic areas. In this study, we collected 18 NPC biopsy specimens from the Hunan Province in southern China and de novo assembled 18 NPC biopsy specimen-derived EBV (NPC-EBV) genomes, designated HN1 to HN18...

BACKGROUND: Hematological and neurological expressed 1 (HN1) is upregulated in many tumors, but the role of HN1 in breast cancer progression and its regulatory mechanism have not been well understood. METHODS: To study the role of HN1 in the initiation and progression of breast cancer, we examined HN1 levels in breast cancer cells and tissues and analyzed the relationship between HN1 levels and patient survival. We used mammosphere formation assay, side population analysis, wound healing assay, transwell assay, soft agar formation assay, and xenografted tumor model to determine the effect of HN1 on the expansion of breast cancer stem cells, and the migration, invasion and tumorigenesis of breast cancer...

Functional magnetic resonance imaging has been widely used to investigate the effects of acupuncture on neural activity. However, most functional magnetic resonance imaging studies have focused on acute changes in brain activation induced by acupuncture. Thus, the time course of the therapeutic effects of acupuncture remains unclear. In this study, 32 patients with amnestic mild cognitive impairment were randomly divided into two groups, where they received either Tiaoshen Yizhi acupuncture or sham acupoint acupuncture...

The complete nucleotide sequence of a double-stranded RNA (dsRNA) mycovirus, Fusarium graminearum dsRNA virus 5 (FgV5), was identified and characterized. The FgV5 genome comprises two dsRNA genome segments of 2030 bp and 1740 bp. FgV5 dsRNA1 contains a single open reading frame (ORF1), which is predicted to encode a protein of 613 amino acids (aa) with a molecular mass of 70.4 kDa and has a conserved RNA-dependent RNA polymerase (RdRp) motif. FgV5 dsRNA2 is predicted to contain two discontinuous ORFs (ORF2 and ORF3) that code for products of unknown function...

Electron attachment to double-stranded cytosine-rich DNA, dCpdC:dGpdG, has been studied by density functional theory. This system represents a minimal descriptive unit of a cytosine-rich double-stranded DNA helix. A significant electron affinity for the formation of a cytosine-centered radical anion is revealed to be about 2.2 eV. The excess electron may reside on the nucleobase at the 5' position (dC˙(-)pdC:dGpdG) or at the 3' position (dCpdC˙(-):dGpdG). The inter-strand proton transfer between the radical anion centered cytosine (N3) and the paired guanine (HN1) results in the formation of radical anion center separated complexes dC1H˙pdC:dG2-H(-)pdG and dCpdC2H˙:dGpdG1-H(-)...

The Notch receptor is a key component of a core metazoan signaling pathway activated by Delta/Serrate/Lag-2 ligands expressed on an adjacent cell. This results in a short-range signal with profound effects on cell-fate determination, cell proliferation, and cell death. Key to understanding receptor function is structural knowledge of the large extracellular portion of Notch which contains multiple repeats of epidermal growth factor (EGF)-like domains. Here we investigate the EGF4-13 region of human Notch1 (hN1) using a multidisciplinary approach...

INTRODUCTION: "Radiomics" extracts and mines a large number of medical imaging features in a non-invasive and cost-effective way. The underlying assumption of radiomics is that these imaging features quantify phenotypic characteristics of an entire tumor. In order to enhance applicability of radiomics in clinical oncology, highly accurate and reliable machine-learning approaches are required. In this radiomic study, 13 feature selection methods and 11 machine-learning classification methods were evaluated in terms of their performance and stability for predicting overall survival in head and neck cancer patients...
