We show that the five-dimensional Maxwell theory with the Chern-Simons term is tachyonic in the presence of a constant electric field. When coupled to gravity, a sufficiently large Chern-Simons coupling causes instability of the Reissner-Nordström black holes in anti-de Sitter space. The instability happens only at non-vanishing momenta, suggesting a spatially modulated phase in the holographic...

A number of issues in heterotic double field theory are studied. This includes the analysis of the T-dual configurations of a flat constant gauge flux background, which turn out to be non-geometric. Performing a field redefinition to a nongeometric frame, these T-duals take a very simple form reminiscent of the constant Qand R-flux backgrounds. In addition, it is shown how the analysis of arXiv...

Overnight exposure of Salmonella enterica serovar Typhimurium to sublethal amounts of Origanum vulgare essential oil (OV) and carvacrol (CAR) did not result in direct and cross-bacterial protection. Cells subcultured with increasing amounts of OV or CAR survived up to the MIC of either compound, revealing few significant changes in bacterial susceptibility.

The four-point correlation function of two 1/2 BPS primaries of conformal weight ∆ = 2 and two 1/2-BPS primaries of conformal weight ∆ = n is calculated in the large λ, large N limit. These operators are dual to Kaluza–Klein supergravity fields sk with masses m = −4 and m = n(n−4). Given that the existing formalism for evaluating sums of products of SO(6) tensors that determine the effective co...

Objective To study the effectiveness of public health interventions in preventing Opisthorchis viverrini (OV) re-infection high-prevalence areas Thailand. Methods 68 people from Sisaket, province with second-highest prevalence Thailand, who tested positive for OV eggs faeces and took praziquantel before start study, participated. 34 participants were allocated to experimental group, which recei...

BACKGROUND The human liver fluke, Opisthorchis viverrini, is designated as a group 1 carcinogen, and is the major risk factor for cholangiocarcinoma in endemic countries throughout Southeast Asia. Proteins in the excretory-secretory products and tegumental surface membranes of the fluke have been proposed to play pivotal roles in parasite survival in the host, and subsequent pathogenesis. These...

Objective—To evaluate the eVects of acute and chronic stimulation in the anteromedial part of the globus pallidus internus (GPi) on the symptoms of patients with Parkinson’s disease. Methods—Six patients with severe Parkinson’s disease (Hoehn and Yahr stage 4–5 in “oV” drug condition) with motor fluctuations and levodopa induced dyskinesia (LID) were operated on. Chronic electrodes were implant...

PURPOSE Natural killer T (NKT) cells are important mediators of antitumor immune responses. We have previously shown that ovarian cancers shed the ganglioside GD3, which inhibits NKT-cell activation. Ovarian cancers also secrete high levels of VEGF. In this study, we sought to test the hypothesis that VEGF production by ovarian cancers suppresses NKT-cell-mediated antitumor responses. EXPERIM...

We studied the role of miRNA-200 family members in cellular sensitivity to paclitaxel and carboplatin, using two ovarian cancer cell lines, OVCAR-3 and MES-OV, and their paclitaxel resistant variants OVCAR-3/TP and MES-OV/TP. Both resistant variants display a strong epithelial-mesenchymal transition (EMT) phenotype, with marked decreases in expression of miR-200c and miR-141 in OVCAR-3/TP, and ...

Liposomal anticancer agents can effectively deliver drugs to tumor lesions, but their therapeutic effects are enhanced in only limited number of patients. Appropriate biomarkers to identify responder patients to these liposomal agents will improve their treatment efficacies. We carried out pharmacological and histopathological analyses of mouse xenograft models bearing human ovarian cancers (Ca...
