This paper investigates the use of a method based on Cu decoration and neutron activation to determine the total volume of voids in a silicon single crystal. A measurement protocol was developed and tested in an experiment carried out with a 5 cm(3) volume and 10 g mass high-purity natural silicon sample. The few percent uncertainty reached in the determination of the Cu concentration, at a 10(14) cm(-3) level, makes this method a candidate to set an upper limit to the concentration of the vacancies contributing to the void volume in the enriched silicon material used to determine the Avogadro constant...

Wine lees, a major waste product of winemaking, is a rich source of polyphenolic compounds. LED-light irradiation at 400-nm elicited microbicidal activity of aqueous extract from wine lees (WLE) against Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans, in addition to reactive oxygen species (ROS) formation, including hydroxyl radical (·OH) and hydrogen peroxide (H2O2). Although treatment for 20 min of photoirradiation alone exerted bactericidal activity with a 2- to 3-log reduction, photoirradiated WLE for 20 min achieved a 5-log or greater reduction in viable S...

A highly enantioselective synthetic route to hexahydropyrrolo[2,3-b]indoles via Lewis acid-catalyzed SN2-type ring opening of activated aziridines with indoles having substitutions at 3- and other positions followed by cyclization in a domino fashion has been developed. Hexahydropyrrolo[2,3-b]indoles have been detosylated in the same pot to afford the corresponding products with free NH group in excellent yields (up to 95%) and enantioselectivity (up to >99%).

OBJECTIVES: The efficacy of sofosbuvir plus ribavirin (RBV) treatment for hepatitis C virus (HCV) genotype 2 focusing on virological response was compared with that of pegylated interferon (peg-IFN) plus RBV treatment. Safety of the former focusing on the decline in hemoglobin levels was compared with that of the latter and assessed in terms of age and inosine triphosphatase (ITPA). METHODS: Patients (n = 17) receiving sofosbuvir plus RBV and those (n = 24) receiving peg-IFN plus RBV diagnosed with chronic HCV genotype 2 were enrolled in this study, and the efficacy and safety of both treatments were assessed...

BACKGROUND: Ventilator-associated pneumonia (VAP) is a common nosocomial infection in pediatric intensive care units (ICUs). Ventilator-associated pneumonia protocols decrease the incidence of VAP; however, many components of these protocols are not feasible in all settings. This study was done in a large pediatric hospital in Nicaragua. OBJECTIVE: The aim of this study is to implement a sustainable evidence-based VAP protocol, in a different culture, for the purpose of decreasing VAP rates...

Polyelectrolyte complexes (PECs) between poly(acrylic acid) (PAA) and poly(diallyldimethylammonium chloride) (PDADMAC), a model system forming coacervate particles via electrostatic interaction at pH 10, were prepared by a stopped-flow (SF) fast mixing technique at different mixing charge ratios (z) and ionic strengths. Both PEC final morphologies prepared by either SF or manual one-shot mixing are similar at bench time. In situ light scattering combined with the SF technique pointed-out, however, the presence of three distinct early stage kinetic behaviors in the formation of PECs...

Intrahepatic cholangiocarcinoma (ICC) is the second most common primary liver neoplasm, followed by hepatocellular carcinoma. ICC can be further subclassified as (i) perihilar and (ii) peripheral types, the latter histologically resembling small-sized intrahepatic bile ducts, such as interlobular bile ducts, cholangioles/ductules and the canals of Hering. Cholangiolocellular carcinoma (CoCC), now classified by the World Health Organization as a subtype of combined hepatocellular-cholangiocarcinoma, is currently regarded as a subtype of peripheral-type ICC...

Nuclear factor-κB (NF-κB) is the most potent pro-inflammatory transactivator, and an inhibitor of NF-κB is a good anti-inflammatory drug. Glucocorticoids (GCs) are the strongest and the most frequently used anti-inflammatory drugs. GCs-bound glucocorticoid receptor (GR) inhibits the transcriptional activity of NF-κB, and thereby suppresses a broad range of inflammatory processes. Concurrently, in whole body out side of inflammation area, GR exerts a lot of hormone action, which results in severe side effects...

Leishmania donovani transformation to amastigote from promastigote during mammalian host infection; displays the immense adaptability of the parasite to survive under stress. Induction of translation initiation factor 2-alpha (eIF2α) phosphorylation by stress specific eIF2α kinases is the basic stress perceiving signal in eukaryotes to counter stress. Here, we demonstrate that elevated temperature and acidic pH; induces phosphorylation of Leishmania donovani eIF2α (LdeIF2α). The in-vitro inhibition experiments suggest interference of LdeIF2α phosphorylation under elevated temperature and acidic pH debilitates parasite differentiation and reduces parasite viability (P< 0...

Since the appearance of recombinant human growth hormone (rhGH) in the 80's, its expansion and acquisition through the black market has increased, so the detection of its abuse continues to be a challenge at present. New biomarkers that are more reliable and sensitive, allowing a larger detection window, are still needed. In this line, Fibronectin 1 (FN1) has been proposed as potential genetic and protein biomarker of rhGH abuse in peripheral blood lymphocytes, serum and plasma. However, logistic problems associated with current blood collection in sports drug testing points towards potential new alternative matrices that could be good candidates to be evaluated...
