BACKGROUND Anal carcinoma is a rare cancer. Surgical treatment is applied for small superficial tumors of the anal margin, the more advanced disease is treated with concomitant chemoradiotherapy. The aim of our study was to evaluate treatment outcomes in patients treated at the Masaryk Memorial Cancer Institute in 2006- 2010. PATIENTS AND METHODS We reviewed the clinical data of 29 newly diag...

Let tsp(G) denote the length of a shortest travelling salesman tour in a graph G. We prove that for any ε > 0, there exists a simple 2-connected planar cubic graph G1 such that tsp(G1) ≥ (1.25 − ε) · |V (G1)|, a simple 2-connected bipartite cubic graph G2 such that tsp(G2) ≥ (1.2 − ε) · |V (G2)|, and a simple 3-connected cubic graph G3 such that tsp(G3) ≥ (1.125− ε) · |V (G3)|.

The National Rotavirus Reference Centre together with collaborating laboratories Australia-wide has conducted rotavirus surveillance since June 1999. This report describes the serotypes of rotavirus strains responsible for the hospitalisation of children with acute gastroenteritis during the period 1 July 2005 to 30 June 2006. Eight hundred and forty-eight faecal samples from across Australia w...

To examine the epidemiology of rotaviruses in Buenos Aires, Argentina, we screened 1,212 stool samples from children with diarrhea in the southern district of Buenos Aires from 1999 to 2003. We identified 187 samples (15.4%) that were positive for group A rotavirus by use of antigen enzyme-linked immunosorbent assay. Among these specimens, 112 were available for typing: 93 (83.0%) were single-t...

We report on two children with mild encephalopathy with a reversible splenial lesion associated with group A rotavirus (GARV) infection. We examined stool, serum, and cerebrospinal fluid samples to determine the presence of the GARV VP7 gene and GARV antigen by reverse-transcription PCR and enzyme-linked immunosorbent assay, respectively. GARV antigen was detected in stool samples from both pat...

BACKGROUND We performed phylogenetic and sequence analysis by Basic Local Alignment Search Tool (BLAST) of a complete Human Rotavirus (HRV) genome isolated from a hospitalized child with acute gastroenteritis in Thailand. FINDINGS The results indicated an uncommon strain characterized by multiple re-assortments in the VP3, VP4, VP6, NSP1, NSP4 and NSP5 genes. The uncommon strain is genotype G...

Aggrecan is the major proteoglycan of the extracellular matrix in cartilage. It contains two N-terminal globular regions, G1 and G2, and one C-terminal globular region, G3. G3 is implicated in the intracellular processing of aggrecan and contains a C-type lectin carbohydrate recognition domain (CRD), frequent occurrences of a C-terminal short complement repeat (SCR) domain, and occasionally an ...

Long non-coding RNAs (LncRNAs) have been reported to be involved in tumorigenesis and tumor progression. Single nucleotide polymorphisms (SNPs) in the lncRNAs also play a vital role in carcinogenesis. The aim of this study was to assess the relationships between the four selected tagSNPs (rs944289, rs3787016, rs1456315, rs7463708) in the lncRNAs and the risk of female breast cancer in a Chinese...

Neuroendocrine neoplasms (NENs) are rare, heterogeneous and ubiquitous tumors commonly localized in the gastrointestinal tract, lung, and pancreas. The clinical behavior of NEN is highly unpredictable; in fact, low-grade cases can unexpectedly be associated with metastases. Currently, the 2010 WHO NEN classification employs histological differentiation and the proliferation index for grading tu...

In the present paper, we study rotational surfaces in the three dimensional pseudo-Galilean space G3. Also, we classify linear Weingarten rotational surfaces in G3. A linear Weingarten surface is the surface having a linear equation between the Gaussian curvature and the mean curvature of a surface. In last section, we construct isotropic rotational surfaces in G3 with prescribed mean curvature...
