The regulatory roles of long noncoding RNAs (lncRNAs) in transcriptional coactivators are still largely unknown. Here, we have shown that the peroxisome proliferator-activated receptor γ (PPARγ) coactivator α (PGC-1α, encoded by Ppargc1a) is functionally regulated by the lncRNA taurine-upregulated gene 1 (Tug1). Further, we have described a role for Tug1 in the regulation of mitochondrial function in podocytes. Using a murine model of diabetic nephropathy (DN), we performed an unbiased RNA-sequencing (RNA-seq) analysis of kidney glomeruli and identified Tug1 as a differentially expressed lncRNA in the diabetic milieu...

The synthesis of mono- and difunctionalized [Re(η(6)-C6H5R)(η(6)-C6H6-nRn)](+) (n = 0, 1; R = COOH, Br) complexes starting from [Re(η(6)-benzene)2](+) is described. The lithiation of [Re(η(6)-benzene)2](+) with n-BuLi leads preferentially to the neutral, alkylated product [Re(η(6)-C6H6)(η(5)-C6H6-Bu)] but not to the expected deprotonation of the arene ring. Deprotonation/lithiation with LDA gave the mono- and the dilithiated products in situ. Their reactions with 1,1,2,2-tetra-bromoethane (TBE) or with CO2, respectively, gave [Re(η(6)-C6H5Br)(η(6)-C6H6)](+), [Re(η(6)-C6H5Br)2](+), or [Re(η(6)-C6H5COOH)(η(6)-C6H6)](+), [Re(η(6)-C6H5COOH)2](+)...

BACKGROUND: E protein of tick-borne encephalitis virus (TBEV) and other flaviviruses is located on the surface of the viral particle. Domain III of this protein seems to be a promising component of subunit vaccines for prophylaxis of TBE and kits for diagnostics of TBEV. METHODS: Three variants of recombinant TBEV E protein domain III of European, Siberian and Far Eastern subtypes fused with dextran-binding domain of Leuconostoc citreum KM20 were expressed in E...

Tick-borne encephalitis (TBE) is an acute febrile illness with neurological manifestations that is prevalent in forested areas of moderate climate in Europe and Asia. TBE virus is transmitted by ticks and rarely by unpasteurized milk and dairy products. The disease burden is attributed mainly to resulting long-term disability, especially in individuals over 50 years of age. Currently, there is no causative treatment, but a very effective vaccination is available with a good safety profile. The vaccination requires three basic doses to be fully effective and regular boosters afterwards...

Tick-borne encephalitis (TBE) is an arbovirus induced by tick-borne encephalitis virus (TBEV) transmitted by tick bite. The disease is rare in France (two to three cases per year) but endemic zones extend from Western Europe to the east coast of Asia (10,000-15,000 cases per year). An 8-year-old boy was admitted to our pediatric ward in Strasbourg (France) for febrile headache with diplopia. Four days after a tick bite, he declared a febrile headache together with maculopapular rash on the elbows, knees, and cheeks...

The diagnosis of achalasia is generally made based on patient symptoms, the appearance of the esophagus on endoscopy and barium esophagogram, and esophageal manometry. In addition, timed barium esophagography (TBE) can give useful information on the clearance of liquid barium over a 10 minute period and the passage of a barium tablet. What is unclear is how well these physiological measurements of esophageal function correlate with patient-perceived health-related quality of life. Our aim was to assess whether objective physiological measurements of high-resolution manometry (HRM) and TBE will correlate with quantitative achalasia-related health-related quality of life (HRQoL) measurements...

Population and family-based genetic studies typically result in the identification of genetic variants that are statistically associated with a clinical disease or phenotype. For many diseases and traits, most variants are non-coding, and are thus likely to act by impacting subtle, comparatively hard to predict mechanisms controlling gene expression. Here, we describe a general strategic approach to prioritize non-coding variants, and screen them for their function. This approach involves computational prioritization using functional genomic databases followed by experimental analysis of differential binding of transcription factors (TFs) to risk and non-risk alleles...

Tick-borne encephalitis (TBE) represents one of the most serious arboviral neuro-infections in Europe and northern Asia. As no specific antiviral therapy is available at present, there is an urgent need for efficient drugs to treat patients with TBE virus (TBEV) infection. Using two standardised in vitro assay systems, we evaluated a series of 29 nucleoside derivatives for their ability to inhibit TBEV replication in cell lines of neuronal as well as extraneural origin. The series of tested compounds included 2'-C- or 2'-O-methyl substituted nucleosides, 2'-C-fluoro-2'-C-methyl substituted nucleosides, 3'-O-methyl substituted nucleosides, 3'-deoxynucleosides, derivatives with 4'-C-azido substitution, heterobase modified nucleosides and neplanocins...

BACKGROUND: Manometric criteria to diagnose achalasia are absent peristalsis and incomplete relaxation of the esophagogastric junction (EGJ), determined by an integrated relaxation pressure (IRP) >15 mm Hg. However, EGJ relaxation seems normal in a subgroup of patients with typical symptoms of achalasia, no endoscopic abnormalities, stasis on timed barium esophagogram (TBE), and absent peristalsis on high-resolution manometry (HRM). The aim of our study was to further characterize these patients by measuring EGJ distensibility and assessing the effect of achalasia treatment...

Molecular genetic techniques and approaches in epidemiological studies were breakthrough in the understanding of the laws, ways, and mechanisms of the spread of the pathogens. However, lack of standard methods makes it difficult to compare results obtained by different scientific groups. In this work we propose to choose one fragment of the TBEV genome as a genetic marker whose sequencing would be both obligatory and sufficient for the molecular epidemiological studies. The best candidate for this purpose may be a fragment of the gene E of 454 nucleotides in length...

We report a case of human tick-borne encephalitis (TBE) in which the TBE virus was isolated from the biting tick. Viral growth and sequence were characterized and compared with those of a reference strain. Virus isolation from ticks from patients with TBE may offer a new approach for studies of epidemiology and pathogenicity.

A series of imidazolium-based porous organic polymers (POP-Ims) was synthesized through Yamamoto reaction of 1,3-bis(4-bromophenyl)imidazolium bromide and tetrakis(4-bromophenyl)ethylene. Porosities and hydrophilicity of such polymers may be well tuned by varying the ratios of two monomers. POP-Im with the highest density of imidazolium moiety (POP-Im1) exhibits the best dispersity in water and the highest efficiency in removing Cr2O7(2-). The capture capacity of 171.99 mg g(-1) and the removal efficiency of 87...
