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 ...
-
(Universidad de Chile, 2012)El desarrollo embrionario en vertebrados es coordinado por una red de señales y factores de crecimiento que comandan diferentes procesos celulares. Sonic Hedgehog (SHH), es un ligando considerado como un regulador maestro ...
-
(Universidad de Chile, 2014)Reproduction is regulated through the integration of information that comes from the hypothalamus, hypophysis, and the ovary. There are critical hormone sensitive periods during development during which they are especially ...
-
(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 ...
-
(ENDOCRINE SOC, 2002-04)The neurotrophin nerve growth factor (NGF) and its two membrane-anchored receptors are expressed in the developing ovary before the organization of the first primordial follicles. In the absence of NGF, the growth of ...
-
(Amer Soc Microbiology, 2021)Leishmania parasites are the causal agent of leishmaniasis, an endemic disease in more than 90 countries worldwide. Over the years, traditional approaches focused on the parasite when developing treatments against ...
-
(Academic Press Inc., 2007)It is known the interactions between the neural plate and epidermis generate neural crest (NC), but it is unknown why the NC develops only at the lateral border of the neural plate and not in the anterior fold. Using ...
