Objective: To assess the role of early prophylaxis with recombinant activated factor VII (rFVIIa) in young haemophiliacs with inhibitors and to determine whether it can reduce bleeding episodes and prevent joint damage. Patients and Methods: Ten severe haemophiliacs, less of three years old, with up to four joint bleeds and inhibitors to FVIII who started early prophylaxis with rFVIIa, were included. A number of haemorrhages/year/patient and haemarthroses/ year/patient were compared before the start of prophylaxis, which include both the time before (initial period) and after inhibitor diagnosis (inhibitor period), with those during prophylaxis (prophylaxis period). Results: The mean time of inhibitor diagnosis was 15.6 months (range: 2.3-34.1). The mean time between inhibitor diagnosis and the start of prophylaxis was 7.1 months (range: 0-23.2), shorter than the time of rFVIIa prophylaxis (mean: 10.3 months;range: 4.1-32.0). Bleeding episodes for the three time periods were 45, 36 and 17, respectively, or 0.29 and 0.51 haemorrhages/year/patient in the two periods prior to prophylaxis compared to 0.17 during prophylaxis. Total haemarthroses for the three-time periods were 7, 5 and 5, respectively. The haemarthroses/year/patient in the pre-prophylaxis period were 0.032 and 0.070, compared to0.049 inthe prophylaxis period. rFVIIa schedules were either 90 μg/kg three times weekly or 90 μg/kg daily. Conclusions: Early prophylaxis with rFVIIa may be efficacious in young haemophiliacs with inhibitors, reducing joint bleeds. After the risky period of inhibitor presence, they are able to continue rFVIII prophylaxis with success assured to prevent arthropathy.

Synthesis of activated carbons from black sapote seeds,characterization and application in the elimination of heavy metals and textile dyes

Chinese Journal of Chemical Engineering 2020年第2期28卷 613-623页

作者： Alejandra Alicia Peláez-cid Vincent Romero-Hernández ana María Herrera-González Alejandro Bautista-Hernández Oscar Coreno-Alonso Facultad de Ingeniería Benemérita Universidad Autónoma de PueblaMexico Instituto de Ciencias Básicas e Ingeniería Universidad Autónoma del Estado de HidalgoMexico División de Ingenierías Universidad de GuanajuatoMexico

Many different techniques may be used to remove industrial pollutants from wastewater. Adsorption using activated carbon has been reported to be an effective method. This work proposes the use of a vegetable residue(black sapote seeds) as a raw material for its synthesis. These carbons were chemically activated using phosphoric acid and carbonized at 673 and 873 K. Adsorption isotherms were constructed for the textile dyes on the carbons, and this data was treated using Langmuir’s equation to quantitatively describe the adsorption process. The synthesized carbons were characterized using FTIR, EA, SEM, Nitrogen adsorption(specific surface areas of 879 and 652 m2·g-1), and their points of zero charge(2.1 and 2.3). It was possible to adsorb both heavy metals and textile dyes present in aqueous solutions and wastewaters using these activated carbons. Heavy metals were adsorbed almost completely by both carbons. Cationic dyes where adsorbed(58–59.8 mg·g-1) in greater amounts compared to anionic dyes(10–58.8 mg·g-1). The amount of anionic dyes adsorbed increased almost 30% by changing the pH of the solutions. One of the carbons was thermally regenerated on three occasions without losing its adsorption capacity and it was proved in a flow system.

The Pattern of Sediment Dispersion in the Front Sector of the Stenhouse and Ajax Glaciers, Visca Anchorage, King George Island, Antarctica

This study investigated the dispersal pattern of suspended sediment in the areas near the Stenhouse and Ajax glaciers, Visca Anchorage, Martel Inlet, King George Island, Antarctica. This study was conducted using visible band processing of Quickbird high-resolution spatial images obtained in October 2006. The methodology was also based on the collection and interpretation of data obtained from water samples collected in Admiralty Bay in December 2004. The digital processing of satellite images was performed using a classification method based on the reflectance characteristics of water. The classified images improved visual identification of the dispersion pattern of suspended sediments in the study area. These data were related to the interpretation of analyses conducted on suspended particulate matter (SPM) in the water. The sediment dispersal pattern observed may be associated with glacial erosion processes, their input of meltwater from the front of the glaciers into the study area, detritus flow processes and glaciomarine circulation in the region.

Modern Built Heritage Conservation Policies: How to Keep Authenticity and Emotion in the Age of Digital Culture

引用

Built Heritage 2018年第2期2卷 17-34页

作者： ana Tostões Instituto Superior Técnico Universidade de LisboaLisbonPortugal

The Modern Movement has demonstrated its long-term legitimacy as a lasting concept endowed with longevity.Relating technology,spatial form and social commitment to one another,through an optimistic faith in progress,modern architects sought to attain new heights of functionality and flexibility in use.The current challenge is to find ways to deal with the conservation of this recent legacy in the continuously changing context of current times,including physical,economic,functional,and fast-moving socio-cultural and political values.To address these questions,‘Modern built heritage conservation policies’explores the restoration and renovation processes undertaken in some paradigmatic case studies:the Tugendhat House(Mies van der Rohe and Lilly Reich,Brno,Czech Republic,1929-1930),the Crown Hall(Mies van der Rohe,Chicago,USA,1950-1956),the National Museum of Western Art(Le Corbusier,Tokyo,Japan,1959)and the Gulbenkian Foundation(Alberto Pessoa,Pedro cid e Ruy d’Athouguia,Lisbon,Portugal,1959-1969).

Severe Acute Respiratory Syndrome Coronavirus(SARS-CoV)-2 infection induces an exacerbated inflammation driven by innate immunity components.Dendritic cells(DCs)play a key role in the defense against viral infections,for instance plasmacytoid DCs(pDCs),have the capacity to produce vast amounts of interferon-alpha(IFN-α).In COVID-19 there is a deficit in DC numbers and IFN-αproduction,which has been associated with disease severity.In this work,we described that in addition to the DC deficiency,several DC activation and homing markers were altered in acute COVID-19 patients,which were associated with multiple inflammatory markers.Remarkably,previously hospitalized and nonhospitalized patients remained with decreased numbers of CD1c+myeloid DCs and pDCs seven months after SARS-CoV-2 infection.Moreover,the expression of DC markers such as CD86 and CD4 were only restored in previously nonhospitalized patients,while no restoration of integrinβ7 and indoleamine 2,3-dyoxigenase(IDO)levels were observed.These findings contribute to a better understanding of the immunological sequelae of COVID-19.
