[Radionuclide synoviorthesis in hemophilia: experience in 107 patients].

Background: In patients with hemophilia, radionuclide synoviorthesis, or the intra-articular injection of a radionuclide to decrease the synovial hypertrophy tissue, aims to decrease or avoid hemarthrosis.

Aim: To evaluate the effectiveness of radionuclide synoviorthesis in hemophilia.

Material And Methods: Observational retrospective study of the evolution of 107 male patients aged 3 to 54 years who were subjected to radionuclide synoviorthesis between 2007 and 2015.

Keggin-structure heteropolyacid supported on alumina to be used in trans/esterification of high-acid feedstocks.

Heteropolyacids (HPA) with Keggin structures, such as HPMoO (HPMo), have been described as efficient catalysts in trans/esterification reactions due to their tolerance to water and free fatty acids contents, with particularly well-suited characteristics of high proton mobility and stability. The versatile array of HPA is considerably increased when such catalysts are supported onto solid matrices. In this sense, AlO was assessed as support for HPMo to be used in trans/esterification reactions to produce biodiesel from high-acid feedstocks.

Improvement on D-xylose to Xylitol Biotransformation by Candida guilliermondii Using Cells Permeabilized with Triton X-100 and Selected Process Conditions.

Cells of Candida guilliermondii permeabilized with Triton X-100 were able to efficiently produce xylitol from a medium composed only by D-xylose and MgCl·6HO in potassium phosphate buffer, at 35 °C and pH 6.5. Under these conditions, the results were similar to those obtained when cofactor and co-substrate or nutrients were added to the medium (about 95 % D-xylose was assimilated producing 42 g/L of xylitol, corresponding to 0.

[Bacteremia in cancer patients. Experience in a pediatric hospital].

Unlabelled: The use of intensive chemotherapy has improved survival of children with cancer. However, this is associated to severe and maintained neutropenia, increasing risks of severe infections like bacteremia.

Aim: To update information on microorganisms involved in bloodstream infections in cancer patients and their antimicrobial resistance patterns during the last 3 years in our hospital, comparing it with our previous experience and with other Chilean centres.

CTAB, Triton X-100 and freezing-thawing treatments of Candida guilliermondii: effects on permeability and accessibility of the glucose-6-phosphate dehydrogenase, xylose reductase and xylitol dehydrogenase enzymes.

Cells of Candida guilliermondii (ATCC 201935) were permeabilised with surfactant treatment (CTAB or Triton X-100) or a freezing-thawing procedure. Treatments were monitored by in situ activities of the key enzymes involved in xylose metabolism, that is, glucose-6-phosphate dehydrogenase (G6PD), xylose reductase (XR) and xylitol dehydrogenase (XD). The permeabilising ability of the surfactants was dependent on its concentration and incubation time.

Individual and interaction effects of vanillin and syringaldehyde on the xylitol formation by Candida guilliermondii.

The effect of lignin degradation products liberated during chemical hydrolysis of lignocellulosic materials on xylose-to-xylitol bioconversion by Candida guilliermondii FTI 20037 was studied. Two aromatic aldehydes (vanillin and syringaldehyde) were selected as model compounds. A two-level factorial design was employed to evaluate the effects of pH (5.
