Single observable concurrence measurement without simultaneous copies

We present a protocol that allows us to obtain the concurrence of any two qubit pure state by performing a minimal and optimal tomography of one of the subsystems through measuring a single observable of an ancillary four dimensional qudit. An implementation for a system of trapped ions is also proposed, which can be achieved with present day experimental techniques.Comment: 4 pages, 1 figur

Reptiles, Squamata, Parque Natural Municipal da Taquara, municipality of Duque de Caxias, state of Rio de Janeiro, Southeastern Brazil

Herein we report a list of the reptiles from Parque Natural Municipal da Taquara, municipality of Duque deCaxias, state of Rio de Janeiro, southeastern Brazil, an area situated in the Atlantic Rainforest Domain. The study wascarried out from September 2006 to October 2008. We recorded 31 species of Squamate reptiles: one species of thefamily Amphisbaenidae; eight species of lizards of the families Anguidae (n = 1), Gekkonidae (1), Phyllodactylidae (1),Polychrotidae (1), Scincidae (1), Teiidae (2), and Tropiduridae (1); and 22 species of snakes of the families Boidae (2),Colubridae (6), Dipsadidae (11), Elapidae (1), and Viperidae (2). Our study indicates that the PNMT is an important area forthe conservation of the Squamate reptile assemblages that inhabit lowlands of Atlantic Rainforest in Brazil

Flavonoids and other compounds from Ouratea ferruginea (Ochnaceae) as anticancer and chemopreventive agents.

The chemical study of the extracts from leaves and stems of Ouratea ferruginea allowed the identification of a new isoflavone, 5-hydroxy-7,3′4′5′-tetramethoxyisoflavone, and twenty two known compounds, including friedelin, 3β-friedelinol, lupeone, a mixture of sitosterol, stigmasterol and campesterol, sitosteryl- and stigmasteryl-3-O-b-D-glucopyranosides, 5,4′-dihydroxy-7,5′,3′-trimethoxyisoflavone, 5,4′-dihydroxy-7,3′-di-methoxyisoflavone (7,3′-di-O-methylorobol), 5,7,4′-trihydroxy-3′,5′-dimethoxyisoflavone (piscigenin), 2R,3R-epicatechin, syringic acid, 2,6-dimethoxybenzoquinone, 2,6-dimethoxyhydroquinone, syringic and ferulic aldehyde, a mixture of vanillic acid, 1-hydroxy-2-methoxy-4-(1E-3-hydroxy-1-propenyl)-benzene and 3,5-dimethoxy-4-hydroxy-dihydrocinamaldehyde, besides amenthoflavone and 7-O-methylamenthoflavone (sequoiaflavone) which are considered as chemotaxonomic markers of Ouratea. The structures were identified by IR, 1H- and 13C-NMR and GC-MS, HPLC-MS, besides comparison with literature data. The inhibitory effects of 5,4′-dihydroxy-7,5′,3′-trimethoxyisoflavone, 7,3′-di-O-methylorobol, piscigenin and 7-O-methylamenthoflavone on cytochrome P450-dependent 7-ethoxycoumarin O-deethylase (ECOD) and glutathione S-transferase (GST) were evaluated in vitro. The 5,4′-dihydroxy-7,5′,3′-trimethoxy-isoflavone was the best inhibitor, inhibiting almost 75% of GST activity. Sequoiaflavone was the most potent inhibitor, inhibiting ECOD assay in 75%. These activities allow us to consider both these flavonoids as potential anticancer and chemopreventive agents

Burkholderia pseudomallei Is Spatially Distributed in Soil in Northeast Thailand

Melioidosis is a severe infection caused by the environmental bacterium Burkholderia pseudomallei. Soil sampling is important to identify geographic regions where humans and animals are at risk of exposure. The purpose of this study was to examine a factor that has a major bearing on the accuracy of soil sampling: the spatial distribution of B. pseudomallei in soil of a specified sampling site. Soil sampling was performed using a fixed-interval grid of 100 sampling points in each of two sites (disused land and rice field) in northeast Thailand, and the presence and amount of B. pseudomallei determined using culture. Mapping of the presence and B. pseudomallei count demonstrated that samples taken from areas adjacent to sampling points that were culture positive (negative) for B. pseudomallei were also likely to be culture positive (negative), and samples taken from areas adjacent to sampling points with a high (low) B. pseudomallei count were also likely to yield a high (low) count (spatial autocorrelation). These data were used as the basis for highlighting several pitfalls in current approaches to soil sampling, together with a discussion of the suitability of a range of sampling strategies in different geographical locations and for different study objectives

Degradabilidade in situ do bagaço de cana-de-açúcar para pequenos ruminantes de raças naturalizadas do Nordeste brasileiro.

Resumo: Com o crescimento da indústria sucroalcooleira, buscam-se alternativas de uso dos resíduos gerados por ela. Os pequenos ruminantes de raças naturalizadas do Nordeste brasileiro mostram-se como grupos potenciais para que seja utilizado o bagaço de cana-de-açúcar (BCA) nas dietas. Nesse contexto, objetivou-se determinar a degradabilidade ruminal in situ da matéria seca (MS) e da fibra em detergente neutro (FDN) do BCA e os parâmetros ruminais em caprinos Moxotó e ovinos Morada Nova, fistulados no rúmen. Contidos em sacos de náilon, 3g de BCA foram incubados no rúmen nos tempos seis, 24 e 96 horas, determinando-se o conteúdo de MS e FDN nos resíduos obtidos. Nos tempos zero, seis e 12 horas após a primeira refeição, mediram-se no líquido ruminal pH e nitrogênio amoniacal (N-NH3) ruminal. O CMS não diferiu entre caprinos e ovinos. O potencial de máxima degradação da MS foi semelhante entre espécies, e da FDN foi superior em caprinos. Ovinos apresentaram maiores tempo de colonização, taxa de degradação e degradabilidade efetiva da MS e FDN. O pH não diferiu entre as espécies. Observou-se maior concentração de N-NH3 ruminal em caprinos, no tempo zero. Diante da maior velocidade de degradação da MS do BCA pelos ovinos, essa espécie se mostra detentora de uma microbiota ruminal com crescimento mais eficiente sobre o BCA. [In situ degradability of sugarcane bagasse for naturalized small ruminant breeds from the northeastern Brazil]. Abstract: With the increase of the sugar and alcohol industries, alternative uses for residue are sought, and the small ruminants from the naturalized breeds of northeastern Brazil are potential groups to make use of the sugarcane bagasse (SCB) in their diets. In this context, the objective was to determine the in situ degradability of dry matter (DM) and neutral detergent fiber (NDF) of SCB and ruminal parameters in Moxotó goats and Morada Nova sheep rumen fistulated. Three grams of SCB were placed in naylon bags and incubated in the rumen at 6, 24 and 96 hours, and the residues analyzed for DM and NDF. Rumen fluid was collected at zero, 6 and 12 hours after the first meal and pH and ammonia nitrogen (N-NH3) were determined. DMI did not differ between goats and sheep. The maximum degradation potential of DM was similar between species and the A of NDF was higher in goats. Sheep had higher colonization time, rate of degradation and effective degradability of DM and NDF. The pH did not differ between species. The highest concentration of ruminal N-NH3 in goats was at time zero. Given the higher rate of degradation of bagasse dry matter by sheep, this specie shows a more efficient rumen microbial growth on SCB

The safety and clinical effectiveness of rapid infusion with CT-P10 in patients with non-Hodgkin's lymphoma or chronic lymphocytic leukemia: A retrospective non-interventional post-authorization safety study in Europe

Rapid infusion (RI) of the rituximab biosimilar CT-P10 is currently only an approved treatment regimen for the treatment of rheumatoid arthritis. Although both CT-P10 and reference rituximab are known to be frequently administered using a RI regimen (≤90 min) in clinical practice, published data on the safety of RI of CT-P10 in patients with NHL and CLL are limited. Hence, this study collected real-world safety and effectiveness data on RI-CT-P10 from the medical records of 196 patients with NHL or CLL in 10 European centers, 6 months after the date of the first RI (index date); the infusion-related reaction (IRR) rate was compared to previously published data. Ten percent (95% confidence interval 6%–15%; n = 20/196) of patients experienced an infusion-related reaction (IRR) on day 1–2 post-index, which was not significantly different (p = 0.45) to the IRR rate for rituximab described in a previous meta-analysis (8.8%). During the observation period, 2% of patients experienced grade 3–5 IRRs and 85% (n = 166) experienced an adverse event (non-IRR). The most common reason for discontinuation of first-line CT-P10 was planned treatment completion (81%; n = 158). Complete response and partial response to CT-P10 was observed in 74% (n = 142/192) and 22% (n = 42/192) of patients, respectively. The results of this real-world study demonstrate that the safety and effectiveness profile of RI-CT-P10 is similar to RI of reference rituximab and therefore support the current use of RI-CT-P10 in patients with NHL and CLL
