(PERGAMON-ELSEVIER SCIENCE LTD, 2003-01)Correction.
-
(ELSEVIER SCIENCE BV, 2003)Potato strips were soaked in 3, 5 or 7% NaCl solutions (25 degreesC) previous to frying, to study the effect on oil uptake. Sensory responses indicated the best texture and lowest oil uptake at 3% NaCl solution for 50 min. ...
-
(Academic Press Inc., 2017)© 2017 Elsevier Inc.A simple and fast spectrophotometric methodology able to quantify superoxide released by NADPH oxidase from differentiated promyelocytic leukaemia (HL-60) cells using pyrogallol red is described.The ...
-
(MDPI, 2020)Nanosystems used in pharmaceutical formulations have shown promising results in enhancing the administration of drugs of difficult formulations. In particular, porous silica nanoparticles have demonstrated excellent ...
-
(Sociedad Chilena de Quimica, 2017)© 2017 Sociedad Chilena de Quimica. All rights reserved. Single crystals of 1,3-bis(cyanomethoxy)calix[4]arene (1) were grown from Chloroform/Methanol mixture and these were nanodecorated with colloidal gold nanoparticles ...
-
(Future Medicine Ltd., 2016)Current strategies for brain diseases are mostly symptomatic and noncurative. Nanotechnology has the potential to facilitate the transport of drugs across the blood-brain barrier and to enhance their pharmacokinetic ...
-
(AMER CHEMICAL SOC, 2006-01)The local heat delivered by metallic nanoparticles selectively attached to their target can be used as a molecular surgery to safely remove toxic and clogging aggregates. We apply this principle to protein aggregates, in ...
-
(Frontiers Media, 2021)Urinary tract infection (UTI) is one of the most common reasons for antibiotic treatment. Nevertheless, uropathogens are steadily becoming resistant to currently available therapies. In this context, nanotechnology emerges ...
-
(Ivyspring International Publisher, 2018)© Ivyspring International Publisher. Cardiovascular diseases are the leading cause of death worldwide. Despite preventive efforts, early detection of atherosclerosis, the common pathophysiological mechanism underlying ...
-
(Bentham, 2015)The treatment of skin wounds represents an important research area due to the important physiological and aesthetic role of this tissue. During the last years, nanoparticles have emerged as important platforms to treat ...
-
Nanostructured interfaces containing MWCNT and nitro aromatics: a new tool to determine Nimesulide (Elsevier, 2020)A novel type of multiwalled carbon nanotube-modified glassy carbon electrode with an entrapped nimesulide drug was constructed. The new electrode surface was characterized by scanning electrochemical microscopy and scanning ...
-
(The American Society of Photobiology, 2013)In this study, we report the synthesis and photochemical behavior of a new family of photoactive compounds to assess its potential as singlet oxygen (1O2) probes. The candidate dyads are composed by a 1O2 trap plus a ...
-
(Elsevier Science Publisher B. V., 1986)Native porins from Salmonella typhi Ty2 outer membrane, and porins alkylated with pyridoxal phosphate (Plp) were studied in planar lipid bilayers. The conductance of bilayers exposed to native or chemically modified porins ...
-
(Wiley, 2017)Gaining new knowledge of the native distributions of species (phylogeography) is more and more difficult in a world affected by anthropogenic disturbance, in particular by species translocations. ...
-
(1983)As part of study of Chagasic cardiopathy in Chile we report a follow-up study of 100 cardiopathic patients from two endemic areas who had been diagnosed 4 years earlier during an epidemiological and clinical survey. The ...
-
(Elsevier B.V., 2017)© 2016 Elsevier B.V. Structured hybrid materials based on the combination adsorbent-photocatalyst with optimal mechanical resistance and reduced cost, are prepared by extrusion using four different natural silicates with ...
-
(Elsevier, 2013)The aim of this work is the experimental and theoretical characterization of the mass transfer in a membrane-based dense gas extraction of metal ions from aqueous solutions using a hollow fiber contactor. Extractions of ...
-
(SOC STUDY REPRODUCTION, 2008-04)A single injection of estradiol valerate (EV) to 14-day-old rats (when the ovarian follicle population has been already established) disrupts cyclicity, increases the activity of key enzymes of androgen biosynthesis, ...
-
(Elsevier INC, 2018)To understand the impact of exposure to steroids in the early step of ovary development(a stage occurring in uterus in humans), we studied neonatal exposure to estradiol valerate (EV) in rats regarding polycystic ovary ...
