A focus on the roles of histones in health and diseases
(Pergamon-Elsevier Science Ltd, 2021-08)
Over time, the knowledge on the role of histones has significantly changed. Initially, histones were only known as DNA packaging proteins but later, it was discovered that they act extracellularly as powerful antimicrobial ...
A combination of sbmA and tolC mutations in Escherichia coli K-12 Tn10-carrying strains results in hypersusceptibility to tetracycline
(American Society for Microbiology, 2008-02)
Previously, we demonstrated that Escherichia coli tolC mutations reduce the high-level resistance to tetracycline afforded by the transposon Tn10-encoded TetA pump from resistance at 200 μg/ml to resistance at 40 μg/ml. ...
Electrochemical stability of glyme-based electrolytes for Li-O2batteries studied by: In situ infrared spectroscopy
(Royal Society of Chemistry, 2020-07)
In situ subtractively normalized Fourier transform infrared spectroscopy (SNIFTIRS) experiments were performed simultaneously with electrochemical experiments relevant to Li–air battery operation on gold electrodes in two ...
Metal ion homeostasis with emphasis on zinc and copper: Potential crucial link to explain the non-classical antioxidative properties of vitamin D and melatonin
(Pergamon-Elsevier Science Ltd, 2021-09)
Metal ion homeostasis is an essential physiological mechanism necessary for achieving an adequate balance of these ions´ concentrations in the different cellular compartments. This fact is of great importance because both ...
Altered Peripheral and Central Inflammatory Responses in a Mouse Model of Autism
(John Wiley & Sons Inc, 2014-04)
Increasing clinical and experimental evidence links immune and inflammatory alterations with the pathogenesis of autism spectrum disorders (ASD). Autistic individuals show signs of neuroinflammation, altered inflammatory ...
Cooperatives battle displacement in Buenos Aires
(Routledge Journals, Taylor & Francis Ltd, 2019-12)
Between 2008-2015, the city of Buenos Aires remained a laboratory for neoliberal policies implemented by a center-right municipal administration opposed to the national government (part of the so called Pink Tide, and ...
Sphingolipids as emerging mediators in retina degeneration
(Frontiers Media S.A., 2019-06-11)
The sphingolipids ceramide (Cer), sphingosine-1-phosphate (S1P), sphingosine (Sph), and ceramide-1-phosphate (C1P) are key signaling molecules that regulate major cellular functions. Their roles in the retina have gained ...
Chronic exposure to urban air pollution from Buenos Aires: The ocular mucosa as an early biomarker
(Springer Heidelberg, 2019-09)
Air pollution represents a major health problem in megacities, bringing about 8 million deaths every year. The aim of the study was to evaluate in vivo the ocular and respiratory mucosa biological response after chronic ...
Biochemical adaptations of the stout razor clam Tagelus plebeius to changes in oxygen availability: Resilience in a changing world?
(National Research Council Canada-NRC Research Press, 2021-02)
Climate change is producing sea level rise and deoxygenation of the ocean, altering estuaries and coastal areas. Changes in oxygen availability are expected to have consequences on the physiological fitness of intertidal ...
The autoimmune response elicited by mouse hepatitis virus (mhv-a59) infection is modulated by liver tryptophan-2,3- dioxygenase (tdo)
(Elsevier Science, 2019-11)
In a previous work we demonstrated that inhibition of mouse indoleamine 2,3-dioxygenase (IDO) by methyltryptophan (MT) exacerbated the pathological actions of mouse hepatitis virus (MHV-A59) infection, suggesting that ...
