As a long term application, this DTM of the tongue could be used to predict the functional consequences of the surgery in terms of speech production and swallowing.
 Further evaluations of the MOR method will include tongue movements induced by multiple muscle activations. At this stage our MOR method offers promising perspectives for the use of the tongue model in a clinical context to predict the impact of tongue surgery on tongue mobility. As a long term application, this DTM of the tongue could be used to predict the functional consequences of the surgery in terms of speech production and swallowing.This study investigated the incidence, genetic diversity, antifungal sensitivity, and virulence of Candida albicans and C. dubliniensis isolated from subjects using dental prostheses and subjects clinically indicated for the first prosthetic rehabilitation. Subjects were divided into four groups and samples were collected twice at first rehabilitation by removable partial (A) and total (C) dental prostheses, and replacement of the removable partial (B) and total (D) prostheses. Yeasts were genotyped using DNA microsatellite markers. Microbiological methods were used to screen for azole antifungal resistance and exoenzyme production. In the initial sampling, oral colonization by Candida was observed in 31 (53.4%) subjects in groups A (33.3%), B (68.2%), and D (65%); 20 (47.6%) subjects displayed colonization of prostheses groups B (50%) and D (45%). The second sampling (±30 days) revealed Candida in 2 (3.4% oral cavity) and 4 (6.9% prosthetic) subjects from group B. C. albicans and C. dubliniensis displayed both polyclonal and monoclonal patterns of infection. Azole-resistant C. albicans and SAPs+ strains were prevalent. Related strains were found in one or several oral sites (mucosa and prosthesis), as well as intra- and inter-subject, -gender, -group, and -time of sampling. However, the patterns of clonality can be altered under dental care.Vibrio cholerae, the causative agent of cholera, tend to colonize the small intestine as a Gram-negative pathogen. The intestinal mucus layer forms mucin physical barrier, consisted of high molecular weight proteins. Regarding the role of toxin-coregulated pilus (TCP) as one of the most important colonization factors of V. cholerae, this experimental study was designed to determine the role of TcpA in induction of mucin production and its regulatory effect on innate immunity molecules including toll like receptors (TLRs) and Nucleotide-binding oligomerization domain-containing proteins (NODs) using Caco2- PBMC co-cultures as an interactive model. The rTcpA protein of V. cholerae was expressed in BL21 Escherichia coli, purified using Ni-column chromatography and confirmed by western blotting. Nontoxic doses of rTcpA was determined on Caco-2 cell lines and different concentrations of rTcpA (1, 5, 10 and 50 μg/mL) showed a statistically significant effect on the expression of muc genes (MUC3 and MUC4) in a dose-dependent manner. This finding is supposed to facilitate physical adhesion and colonization of V. cholerae in intestinal lumen. The rTcpA moderately stimulated the expression of tlr4 and overexpressed tlr1, both of which are supposed to induce a mucosal protective response against bacterial infection. NOD2 was significantly increased which suggests that it may contribute in pro-inflammatory responses observed in cholera disease.  https://www.selleckchem.com/products/neo2734.html  No change in NOD1 expression was seen which might be attributed to the non-invasive nature of V. cholerae as an intestinal pathogen. In conclusion, the rTcpA protein of V. cholerae showed a statistically significant modulatory effect on the human gut epithelium gene expression which would help promising protection in prophylaxis applications.Multiple membrane trafficking networks operate in the eukaryotic cell and are hijacked by viruses to establish infection. Recent studied have highlighted that viruses can exploit distinct pathways depending on the cell type. Japanese encephalitis virus (JEV), a neurotropic flavivirus, can infect neuronal cells through a clathrin-independent endocytic mechanism. To further characterize the membrane trafficking requirements for JEV infection of neuronal cells, we have performed a RNA interference-based study targeting 136 proteins in the human cell line IMR-32. Through quantitative RT-PCR and plaque assays we have validated that JEV infection in neuronal cells was independent of clathrin, and identified host-factors that were crucial for establishment of infection. Several of these proteins were involved in regulation of actin filament organization such as RHOA, RAC1, proteins of the ARP2/3 complex and N-WASP family, LIMK1, PAK1 and ROCK2. The small molecule inhibitors of ARP2/3 complex, CK-548 and of the N-WASP, Wiskostatin inhibited virus replication highlighting the important roles of these proteins in the virus life-cycle. We also identified ATG12, BECN1, VAPA, VAPB and VCP proteins as crucial host-factors for JEV replication across epithelial and neuronal cell lineages.
  Emerging evidence has demonstrated that long noncoding RNAs (lncRNAs) may be closely associated with Hepatitis C virus (HCV) infection and the development of hepatocellular carcinoma (HCC). In this study, we investigated the expression and functions of a lncRNA, LINC01189, in HCV-associated HCC.
 
  LINC01189 expression was measured in HCC tumors, HCV-infected HCC tumors and HCV-infected HCC cells. LINC01189 was overexpressed in HCV-infected HepG2 cells to measure its function on HCV-correlated cancer proliferation. In HCC cell lines of Huh7 and Hep3B, LINC01189 was upregulated to investigate its effects on cancer cell proliferation and 5-FU chemoresistance. The competing endogenous RNA (ceRNA) target of LINC01189, human microRNA-155-5p (hsa-miR-155-5p) was probed by dual-luciferase assay and qRT-PCR. Hsa-miR-155-5p was upregulated in LINC01189-overexpessed Huh7 and Hep3B cells to investigate their epigenetic correlation on HCC development regulation.
 
  LINC01189 is downregulated in HCV-infected HCC tumors and cell lines. LINC01189 overexpression inhibited HCC cancer cell proliferation and 5-FU chemoresistance. Hsa-miR-155-5p was confirmed to be a ceRNA target of LINC01189 in HCC. Upregulating hsa-miR-155-5p reversed the LINC01189-mediated inhibition on HCC proliferation and 5-FU chemoresistance.
 
  LINC01189 downregulation is associated with HCV infection in HCC, and it has tumor-suppressing effects on HCC development through hsa-miR-155-5p.
