The rate of expenditure of the accumulated charge depends on the

The rate of expenditure of the accumulated charge depends on the composition of the nanoparticles and is determined by their electric capacitance. A correlation was found between the photocatalytic activity of the Cd (x) Zn1-x S nanoparticles in the release of hydrogen from solutions of Na2SO3, their composition, and their capacity for photoinduced accumulation of excess charge. It was shown that Ni-0 nanoparticles photodeposited on the surface

of Cd (x) Zn1-x S are effective cocatalysts for the release of hydrogen. It was found that Zn-II additions in photocatalytic systems based on Cd (x) Zn1-x S/Ni-0 nanostructures have a promoting action FG-4592 order on the release of hydrogen from water-ethanol mixtures.”
“A retrospective serosurvey was carried out between 2009 and 2012 to detect antibodies

to Brucella spp. in free-ranging African wildlife ungulates from five selected game parks in Zimbabwe. Samples were drawn from wildlife-livestock interface and non-interface areas in Zimbabwe. A total of 270 serum samples from four different species, namely AS1842856 manufacturer African buffalo (Syncerus caffer) (n = 106), impala (Aepyceros melampus) (n = 72), black rhinoceros (Diceros bicornis) (n = 45) and white rhinoceros (Ceratotherium simum) (n = 47), were tested. The percentage of positive samples was 17.0% in buffalo (18/106; 95% CI: 9.72% -24.1%) and 1.4% in impala (1/72; 95% CI: 0% -4.2%). No antibodies to Brucella spp. were detected in the two rhinoceros species. The difference in the percentage of seropositive Selleck PF-03084014 cases between buffalo and impala was significant (p < 0.05). Seropositivity to Brucella spp. was higher (19.1%) in adult buffalo compared with juveniles and sub-adults younger than six years (5.9%). Further, seropositivity was marginally higher (20.4%) in animals from wildlife-livestock interface areas than in those from non-interface areas (13.45%; OR = 1.45) although the difference was not statistically significant. The study showed that brucellosis could be more widespread in buffalo and

may circulate in this species independently in the absence of contact with cattle, whilst rhinoceros may be considered less susceptible to brucellosis. The role of the wildlifelivestock interface in the epidemiology of brucellosis in wildlife and livestock is probably overstated but needs to be explored further.”
“Objectives: The purpose of this study is to validate the efficacy of intensive statin therapy for patients with atherosclerotic intracranial arterial stenosis (AICAS). Methods: In this study, we performed a single-center, randomized, single-blind, parallel-group clinical trial. A total of 120 Chinese patients with AICAS were enrolled and randomly divided into three groups [low-dose atorvastatin therapy (LAT, 10 mg/day), standard-dose atorvastatin therapy (SAT, 20 mg/day), and intensive-dose atorvastatin therapy (IAT, 40 mg/day) groups] in a 1:1:1 ratio.
