[Young women with HIV infection acquired by vertical transmission: Expectations of having uninfected children].

Introduction: Pediatric antiretroviral therapy (ART), changed the prognosis of the disease, allowing young women infected by vertical transmission (TV) to be pregnant without risk for their fetus of acquiring this infection.

Aim: To describe the clinical-immune status in pregnant women that acquired HV by vertical transmission, treatments received, monitoring of pregnancy and newborn characteristics.

Material And Methods: A protocol was performed, evaluating clinical and immunological parameters during pregnancy, ART used, protocol preventing vertical transmission (PPTV), and follow up of children to 18 months of age.

Gasification Mechanism of Carbon with Supercritical Water at Very High Pressures: Effects on H2 Production.

The scarce data concerning the gasification of carbonaceous solids with supercritical water (SCW) suggest the great potential of this method to produce a valuable green fuel such as H2. However, the extraordinary properties of SCW have not been properly applied to H2 production because the mechanism that governs gasification under these conditions remains unclear. Here, we present a study in which this reaction is explored within the largest pressure range ever assayed in this field, from 1 to 1000 bar.

Breakthrough bacteremia due to Clostridium tertium in a patient with neutropenic fever, and identification by MALDI-TOF mass spectrometry.

Clostridium tertium is rare in a human clinical specimen and its pathogenicity is often uncertain. However, the organism has been increasingly recognized as a cause of bacteremia and other infections in immunocompromised patients, especially those with hematologic malignancies. The diagnosis and treatment of C.

Development of porosity in a char during reaction with steam or supercritical water.

Two series of activated carbon have been prepared by reaction of a char (from olive stones) with supercritical water (SCW) with the objective of studying the effect of temperature and residence time on the development of porosity. The results have been compared with those obtained using the same char but with classical activation with steam. Both procedures develop porosity, but (i) the reaction rate is critical in the development of porosity for steam but not for SCW activation, and (ii) SCW activation produces a larger development of microporosity at low degrees of burnoff, whereas steam produces more meso- and macroporosity.

Comparison between TG-51 and TRS-398: electron contamination effect on photon beam-quality specification.

Two dosimetry protocols based on absorbed dose to water have recently been implemented: TG-51 and TRS-398. These protocols use different beam-quality indices: %dd(10)x and TPR20,10. The effect of electron contamination in measurements of %dd(10)x has been proposed as a disadvantage of the TG-51.
