Oxidative stress, prooxidants and Crohn disease Estrés oxidativo, prooxidantes y enfermedad de Crohn (2006)The frequency of Crohn disease shows a significant increase in the last century. Affected patients show a misbalance between production of free radicals and anti oxidant defenses. Thus, one of the increasingly accepted ...

(Elsevier, 2013)The transient receptor potential melastatin (TRPM) protein family is an extensive group of ion channels expressed in several types of mammalian cells. Many studies have shown that these channels are crucial for performing ...
-
(Hindawi Limited, 2013)Cardiovascular diseases are a leading cause of mortality and morbidity worldwide, with hypertension being a major risk factor. Numerous studies support the contribution of reactive oxygen and nitrogen species in the ...
-
(Clinical Science, 2004-03)Oxidative stress is implicated in the pathogenesis of non-alcoholic fatty liver disease (NAFLD). In the present study, hepatic and plasma oxidative stress-related parameters were measured and correlated with clinical and ...
-
(1991)The quenching by molecular oxygen of the fluorescence of several probes complexed to apohorseradish peroxidase has been studied by intensity and time-resolved fluorescence methods. The probes utilized include 1-anilino-8 ...

(2010-03-05)Volume-sensitive outwardly rectifying (VSOR) Cl channels are critical for the regulatory volume decrease (RVD) response triggered upon cell swelling. Recent evidence indicates that H2O2 plays an essential role in the ...
-
(BIOMED CENTRAL LTD, 2011-02-15)Background: Working memory (WM) tasks usually elicit a P300 ERP component, whose amplitude decreases with increasing WM load. So far, this effect has not been studied in schizophrenics (SZs), a group that is considered to ...
-
P450-aromatase activity and expression in human testicular tissues with severe spermatogenic failure (Blackwell Publishing Ltd, 2010)There is evidence that impaired spermatogenesis is associated with an imbalance in the oestradiol/testosterone ratio and with Leydig cell (LC) dysfunction. In testis, P450-aromatase, encoded by CYP19, is responsible for ...

(2010)Objective: To study the effect of peritoneal fluid from women with (PF-E) and without (PF-C) endometriosis on P450Arom expression in endometrial cells. Design: Experimental study. Setting: University research ...
-
(Public Library Science, 2018)Background Animal growth is influenced by the genetic background and the environmental circumstances. How genes promote growth and coordinate adaptation to nutrient availability is still an open question. p53 is a ...
-
(Microbiology Society, 1998)Analysis of the 16S rRNA genes retrieved directly from different environments has proven to be a powerful tool that has greatly expanded our knowledge of microbial diversity and phylogeny. It is shown here that sequence ...
-
(Sociedad Médica de Santiago, 2020)Isolated cardiac involvement of COVID-19 is an infrequent presentation, and myocardial infarction is even less common. We report a 30-year-old man presenting with retrosternal pain of insidious onset whose intensity increases ...
