1Osteopontin: A non-invasive parameter of portal hypertension and prognostic marker of cirrhosis显示文摘AIM: To investigate the relationship between osteopontin plasma concentrations and the severity of portal hypertension and to assess osteopontin prognostic value.METHODS: A cohort of 154 patients with confirmed liver cirrhosis(112 ethylic, 108 men, age 34-72 years)were enrolled in the study. Hepatic venous pressure gradient(HVPG) measurement and laboratory and ultrasound examinations were carried out for all patients. HVPG was measured using a standard catheterization method with the balloon wedge technique. Osteopontin was measured using the enzyme-linked immunosorbent assay(ELISA) method in plasma. Patients were followed up with a specific focus on mortality. The control group consisted of 137 healthy age- and sex- matched individuals.RESULTS: The mean value of HVPG was 16.18 ± 5.6 mm Hg. Compared to controls, the plasma levels of osteopontin in cirrhotic patients were significantly higher(P < 0.001). The plasma levels of osteopontin were positively related to HVPG(P = 0.0022, r = 0.25) and differed among the individual Child-Pugh groups of patients. The cut-off value of 80 ng/m L osteopontin distinguished patients with significant portal hypertension(HVPG above 10 mm Hg) at 75% sensitivity and 63% specificity. The mean follow-up of patients was 3.7 ± 2.6 years. The probability of cumulative survival was 39% for patients with HVPG > 10 mm Hg and 65% for those with HVPG ≤ 10 mm Hg(P = 0.0086, odds ratio(OR), 2.92, 95% confidence interval(CI): 1.09-7.76). Osteopontin showed a similar prognostic value to HVPG. Patients with osteopontin values above 80 ng/m L had significantly lower cumulative survival compared to those with osteopontin ≤ 80 ng/m L(37% vs 56%, P = 0.00035; OR = 2.23, 95%CI: 1.06-4.68).CONCLUSION: Osteopontin is a non-invasive parameter of portal hypertension that distinguishes patients with clinically significant portal hypertension. It is a strong prognostic factor for survival.Radan Bruha Marie Jachymova Jaromir Petrtyl Karel Dvorak Martin Lenicek Petr Urbanek Tomislav Svestka Libor Vitek 2016World Journal of Gastroenterology2016,22,12:20
2乙烷氧化脱氢用Ni/Al_2O_3催化剂中活性镍物种前驱体(英文)显示文摘Ni/Al2O3 catalysts for oxidative dehydrogenation(ODH) of ethane were prepared by impregnation of Al2O3 with nickel acetate or nickel nitrate,and by mechanical mixing of NiO and Al2O3.The Ni-based catalysts were characterized by N2 adsorption-desorption,X-ray diffraction,diffuse reflectance UV-visible diffuse reflectance spectroscopy,and temperature-programmed reduction of hydrogen.The results showed that formation of crystalline NiO particles with a size of < 8 nm and/or non-stoichiometric NiO species in the Ni/Al2O3 catalysts led to more active species in ODH of ethane under the investigated reaction conditions.In contrast,tetrahedral Ni species present in the catalysts led to higher selectivity for ethene.Formation of large crystalline NiO particles(22-32 nm) over Ni/Al2O3 catalysts decreased the selectivity for ethene.Lucie Smoláková árka Botková Libor apek Peter Priecel Agnieszka Soltysek Martin Kout Lenka Matějová 2013催化学报2013,34,10:2

4Regeneration of neurotransmission transcriptome in a model of epileptic encephalopathy after antiinflammatory treatment显示文摘Inflammation is an established etiopathogenesis factor of infantile spasms(IS), a therapy-resistant epileptic syndrome of infancy. We investigated the IS-associated transcriptomic alterations of neurotransmission in rat hypothalamic arcuate nucleus, how they are corrected by antiinflamatory treatments and whether there are sex differences. IS was triggered by repeated intraperitoneal administration of N-methyl-D-aspartic acid following anti-inflammatory treatment(adreno-cortico-tropic-hormone(ACTH) or PMX53)or normal saline vehicle to prenatally exposed to betamethasone young rats. We found that treatments with both ACTH and PMX53 resulted in substantial recovery of the genomic fabrics of all types of synaptic transmission altered by IS. While ACTH represents the first line of treatment for IS, the even higher efficiency of PMX53(an antagonist of the complement C5 a receptor) in restoring the normal transcriptome was not expected. In addition to the childhood epilepsy, the recovery of the neurotransmission genomic fabrics by PMX53 also gives hope for the autism spectrum disorders that share a high comorbidity with IS. Our results revealed significant sex dichotomy in both IS-associated transcriptomic alterations(males more affected) and in the efficiency of PMX53 anti-inflammatory treatment(better for males). Our data further suggest that anti-inflammatory treatments correcting alterations in the inflammatory transcriptome may become successful therapies for refractory epilepsies.Dumitru A.Iacobas Libor Velísek 2018Neural Regeneration Research2018,13,10:2

6NKX2-3 and IRGM variants are associated with diseasesu sceptibility to IBD in Eastern European patients显示文摘AIM: To investigate variants of immunity-related GT-Pase family M (IRGM) and NKX2-3 genes and genotype-phenotype in Eastern European patients with inflammatory bowel disease (IBD).METHODS: We analyzed 1707 Hungarian and Czech subjects with Crohn’s disease (CD) (n = 810, age: 37.1 ± 12.6 years, duration: 10.7 ± 8.4 years) and ulcerative colitis (UC) (n = 428, age: 43.7 ± 15.0 years, duration: 12.6 ± 9.9 years), as well as 469 healthy controls. IRGM rs13361189, NKX2-3 rs10883365 and ECM1 rs13294 polymorphisms were tested by LightCy-cler allele discrimination. Detailed clinical phenotypes were determined by reviewing the medical charts. RESULTS: NKX2-3 rs10883365 variant allele was as-sociated with increased risk for CD (P = 0.009, OR = 1.24, 95% CI = 1.06-1.48) and UC (P = 0.001, OR = 1.36, 95% CI = 1.13-1.63), whereas variant IRGM allele increased risk for CD (P = 0.029, OR = 1.36, 95% CI = 1.03-1.79). In contrast, ECM1 rs13294 was not associat-ed with either CD or UC. In CD, the variant IRGM allele was associated with a colon-only location (P = 0.02, OR = 1.62, 95% CI = 1.07-2.44), whereas in UC, the ECM1 variant was associated with cutaneous manifestations (P = 0.002, OR = 3.36, 95% CI = 1.48-7.63). Variant alleles did not predict resistance to steroids or azathio-prine, efficacy of infliximab, or need for surgery. CONCLUSION: NKX2-3 and IRGM are susceptibility locifor IBD in Eastern European patients. Further studies are needed to confirm the reported phenotype-genotype associations.Nora Meggyesi Lajos S Kiss Magdalena Koszarska Martin Bortlik Dana Duricova Laszlo Lakatos Tamas Molnar Martin Lenicek Libor Vítek Istvan Altorjay Maria Papp Zsolt Tulassay Pal Miheller Janos Papp Attila Tordai Hajnalka Andrikovics Milan Lukas Peter Laszlo Lakatos 2010World Journal of Gastroenterology2010,16,41:2
