Abstract
Introduction The development of cognitive dysfunction is not necessarily associated with diet-induced obesity. We hypothesized that cognitive dysfunction might require additional vascular damage, for example, in atherosclerotic mice. Methods We induced atherosclerosis in male C57BL/6N mice by injecting AAV-PCSK9DY (2x1011 VG) and feeding them a cholesterol-rich Western diet. After 3 months, mice were examined for cognition using Barnes maze procedure and for cerebral blood flow. Cerebral vascular morphology was examined by immunehistology. Results In AAV-PCSK9DY-treated mice, plaque burden, plasma cholesterol, and triglycerides are elevated. RNAseq analyses followed by KEGG annotation show increased expression of genes linked to inflammatory processes in the aortas of these mice. In AAV-PCSK9DY-treated mice learning was delayed and long-term memory impaired. Blood flow was reduced in the cingulate cortex (-17%), caudate putamen (-15%), and hippocampus (-10%). Immunohistological studies also show an increased incidence of string vessels and pericytes (CD31/Col IV staining) in the hippocampus accompanied by patchy blood-brain barrier leaks (IgG staining) and increased macrophage infiltrations (CD68 staining). Discussion We conclude that the hyperlipidemic PCSK9DY mouse model can serve as an appropriate approach to induce microvascular dysfunction that leads to reduced blood flow in the hippocampus, which could explain the cognitive dysfunction in these mice.

Abstract
Besides being a country with high inequality, Brazil faces an alarming sociohistorical moment in which the coronavirus disease 2019 (COVID-19) pandemic is exacerbating a disastrous political situation that promotes polarization and social division. The context of this situation is described here through a critical lens, as a justification for conceiving a counter-hegemonic proposal based on different views that share the perspective of Global South epistemologies. Santos' (in Santos (ed) Epistemologias do Sul, Coimbra, Edições Almedina, 2009) fundamental principle is that there is no global social justice without global cognitive justice, which is represented by the concept of ecology of knowledge. In a recent publication, Santos (A cruel pedagogia do vírus, Coimbra, Edições Almedina.Santos, 2020) demonstrates that the negative effects of the pandemic on the planet and humanity were exacerbated by the planetary dimensions that capitalism has taken on. The author states that the current health crisis is connected to the ecological crisis, since both are manifestations of this model of society, which is based on the unlimited exploitation of natural resources. Building on these ideas, we envisage a science education that fights for the preservation of the planet, is critical of the capitalist model of society, and values the knowledge of the Global South.

Abstract
Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and death worldwide. Peroxynitrite, formed from nitric oxide, which is derived from inducible nitric oxide synthase, and superoxide, has been implicated in the development of emphysema, but the source of the superoxide was hitherto not characterized. Here, we identify the non-phagocytic NADPH oxidase organizer 1 (NOXO1) as the superoxide source and an essential driver of smoke-induced emphysema and pulmonary hypertension development in mice. NOXO1 is consistently upregulated in two models of lung emphysema, Cybb (also known as NADPH oxidase 2, Nox2)-knockout mice and wild-type mice with tobacco-smoke-induced emphysema, and in human COPD. Noxo1-knockout mice are protected against tobacco-smoke-induced pulmonary hypertension and emphysema. Quantification of superoxide, nitrotyrosine and multiple NOXO1-dependent signalling pathways confirm that peroxynitrite formation from nitric oxide and superoxide is a driver of lung emphysema. Our results suggest that NOXO1 may have potential as a therapeutic target in emphysema.

Abstract
Several studies indicate that music has soothing effects and is effective for reducing stress and anxiety in coronary patients. The effects of stress on the cardiovascular system have also been proven. However, the meanings assigned to music when used during hemodynamic procedures are unknown, as are the meanings of the experience of these procedures. The aim of this research is to understand the senses and feelings of music for patients undergoing hemodynamic procedures, identify and interpret the fantasies and emotions related to, and study the possibility of deploying in hospitals the “Musical Method for Hemodynamic Procedures”, being developed by the author. This research is based on a clinical-qualitative methodology. The sampling method is the theoretical saturation. The semi-structured interview was used in order to obtain data that was submitted to content analysis. The subjects are patients undergoing hemodynamic procedures in hospital SEMPER, Brazil. We conclude that within the experience of listening to music while undergoing catheterisation 100% of the patients claimed they had overcome the experience of stress and felt calm, tranquillity, peace and happiness. Some patients described the music as a companion, as something that diverts their attention from fear, transporting them to an imaginary place, to another dimension. The episodic memory, the capacity to recognize a musical excerpt for which the spatiotemporal context surrounding its former encounter can be recalled, was also important, with surprising results in the case of patients who underwent catheterisation in the presence of music and, later, angioplasty without the presence of music.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
The free radical theory of aging suggests reactive oxygen species as a main reason for accumulation of damage events eventually leading to aging. Nox4, a member of the family of NADPH oxidases constitutively produces ROS and therefore has the potential to be a main driver of aging. Herein we analyzed the life span of Nox4 deficient mice and found no difference when compared to their wildtype littermates. Accordingly neither Tert expression nor telomere length was different in cells isolated from those animals. In fact, Nox4 mRNA expression in lungs of wildtype mice dropped with age. We conclude that Nox4 has no influence on lifespan of healthy mice.

Abstract
OBJECTIVE Reactive oxygen species generated by nicotinamide adenine dinucleotide phosphate (NADPH) oxidases contribute to angiogenesis and vascular repair. NADPH oxidase organizer 1 (NoxO1) is a cytosolic protein facilitating assembly of constitutively active NADPH oxidases. We speculate that NoxO1 also contributes to basal reactive oxygen species formation in the vascular system and thus modulates angiogenesis. APPROACH AND RESULTS A NoxO1 knockout mouse was generated, and angiogenesis was studied in cultured cells and in vivo. Angiogenesis of the developing retina and after femoral artery ligation was increased in NoxO1(-/-) when compared with wild-type animals. Spheroid outgrowth assays revealed greater angiogenic capacity of NoxO1(-/-) lung endothelial cells (LECs) and a more tip-cell-like phenotype than wild-type LECs. Usually signaling by the Notch pathway switches endothelial cells from a tip into a stalk cell phenotype. NoxO1(-/-) LECs exhibited attenuated Notch signaling as a consequence of an attenuated release of the Notch intracellular domain on ligand stimulation. This release is mediated by proteolytic cleavage involving the α-secretase ADAM17. For maximal activity, ADAM17 has to be oxidized, and overexpression of NoxO1 promoted this mode of activation. Moreover, the activity of ADAM17 was reduced in NoxO1(-/-) LECs when compared with wild-type LECs. CONCLUSIONS NoxO1 stimulates α-secretase activity probably through reactive oxygen species-mediated oxidation. Deletion of NoxO1 attenuates Notch signaling and thereby promotes a tip-cell phenotype that results in increased angiogenesis.

Abstract
AIMS Oxidative stress is thought to be a risk for cardiovascular disease and NADPH oxidases of the Nox family are important producers of reactive oxygen species. Within the Nox family, the NADPH oxidase Nox4 has a unique position as it is constitutively active and produces H2O2 rather than [Formula: see text] . Nox4 is therefore incapable of scavenging NO and its low constitutive H2O2 production might even be beneficial. We hypothesized that Nox4 acts as an endogenous anti-atherosclerotic enzyme. METHODS AND RESULTS Tamoxifen-induced Nox4-knockout mice were crossed with ApoE⁻/⁻ mice and spontaneous atherosclerosis under regular chow as well as accelerated atherosclerosis in response to partial carotid artery ligation under high-fat diet were determined. Deletion of Nox4 resulted in increased atherosclerosis formation in both models. Mechanistically, pro-atherosclerotic and pro-inflammatory changes in gene expression were observed prior to plaque development. Moreover, inhibition of Nox4 or deletion of the enzyme in the endothelium but not in macrophages resulted in increased adhesion of macrophages to the endothelial surface. CONCLUSIONS The H2O2-producing NADPH oxidase Nox4 is an endogenous anti-atherosclerotic enzyme. Nox4 inhibitors, currently under clinical evaluation, should be carefully monitored for cardiovascular side-effects.
