How protonation modulates the interaction between proteins and pH-responsive hydrogel films
(Elsevier Science London, 2019-06)
Hydrogels of pH-responsive polymers are promising candidates for the design of functional biomaterials. In this context, understanding the complexity of the interaction between these materials and proteins is essential. A ...
Integrated SPE-Self assembled MEPS platform for ultrasensitive determination of mononitrophenols in water: Experimental, computational and applicability studies
(Elsevier Science, 2020-05)
Integrated analytical approaches can be used to determine the trace concentrations of analytes in water matrices. Here we designed and compared two novel and facile, integrated polysaccharide adsorbent SPE-Self assembled ...
Regional model simulations of the 2008 drought in southern South America using a consistent set of land surface properties
(American Meteorological Society, 2014-09)
This work discusses the land surface-atmosphere interactions during the severe drought that took place in 2008 in southern South America. The drought was among the most severe in the last fifty years both in terms of ...
Metal nanoparticle ensembles: Tunable laser pulses distinguish monomer from dimer vibrations
(American Chemical Society, 2011-07)
Resonant interaction of laser pulses with plasmons is used to identify vibrations associated with isolated spheres and pairs of contacting spheres in a system of gold nanoparticles. The optical pulses generate coherent ...
Prevalence of HIV and other sexually transmitted infections among female commercial sex workers in Argentina
(American Society of Tropical Medicine and Hygiene, 2006-12)
Sexually transmitted infections (STIs) have shown to enhance the transmission of human immunodeficiency virus (HIV) and to be more common among female commercial sex workers (FSWs). A cross-sectional study was conducted ...
Crystal Structure and Functional Analyses of the Lectin Domain of Glucosidase II: Insights into Oligomannose Recognition
(American Chemical Society, 2015-07)
N-Glycans are modified as part of a quality control mechanism during glycoprotein folding in the endoplasmic reticulum (ER). Glucosidase II (GII) plays a critical role by generating monoglucosylated glycans that are ...
Las emociones positivas : su importancia en el marco de la promoción de salud mental en la infanciaThe importation of positive emotions on children's mental health promotion
(Universidad de San Martín de Porres. Facultad de Ciencias de la Comunicación. Turismo y Psicología, 2010-06)
El estudio científico de las emociones positivas es un tópico recientemente explorado en la literatura psicológica a pesar de actuar como un factor protector en situaciones de adversidad, optimizar la salud y el bienestar ...
A Peptidase Enzyme from Bacillus cereus with Antimicrobial Properties: Optimizing the Immobilization in Chitosan Beads Using Box-Behnken Design
(Sciepub, 2016-05)
Enzymes are exploited as catalysts in many industrial, biomedical, and analytical processes. There has been considerable interest in the development of carrier systems for enzyme immobilization because immobilized enzymes ...
Titanium substituted potassium tantalates (KTaxTi1-xO3 x= 1.0, 0.8, 0.6, 0.5): Catalysts for the methyl phenyl sulfide oxidation
(Elsevier, 2020-02)
B-cation titanium substituted potassium tantalates KTaxTi1-xO3 (x=1.0; 0.8; 0.6; 0.5) materials were synthesized, characterized by XRD, N2 adsorption-desorption isotherms, FTIR, DRS-UV-vis, TGA, H2-TPR and XPS to be used ...
HIF-1alpha-regulated MIF activation and Nox2-dependent ROS generation promote Leishmania amazonensis killing by macrophages under hypoxia
(Academic Press Inc Elsevier Science, 2019-01)
Increasing attention is given to the finding that macrophages under hypoxia are capable of controlling infection by the intracellular protozoan parasite Leishmania amazonensis. The hypoxia-inducible factor (HIF)-1α has ...
