Abstract
Cerebrovascular disease accounts for major neurologic disabilities in patients with type 2 diabetes mellitus (DM). A potential association of mitochondrial DNA (mtDNA) and inflammation with cerebral vessel remodeling in patients with type 2 DM was evaluated. A cohort of 150 patients and 30 healthy controls were assessed concerning urinary albumin/creatinine ratio (UACR), synaptopodin, podocalyxin, kidney injury molecule-1 (KIM-1), N-acetyl-β-(D)-glucosaminidase (NAG), interleukins IL-17A, IL-18, IL-10, tumor necrosis factor-alpha (TNFα), intercellular adhesion molecule-1 (ICAM-1). MtDNA-CN and nuclear DNA (nDNA) were quantified in peripheral blood and urine by qRT-PCR. Cytochrome b (CYTB) gene, subunit 2 of NADH dehydrogenase (ND2), and beta 2 microglobulin nuclear gene (B2M) were assessed by TaqMan assays. mtDNA-CN was defined as the ratio of the number of mtDNA/nDNA copies, through analysis of the CYTB/B2M and ND2/B2M ratio; cerebral Doppler ultrasound: intima-media thickness (IMT)-the common carotid arteries (CCAs), the pulsatility index (PI) and resistivity index (RI)- the internal carotid arteries (ICAs) and middle cerebral arteries (MCAs), the breath-holding index (BHI). The results showed direct correlations of CCAs-IMT, PI-ICAs, PI-MCAs, RI-ICAs, RI-MCAs with urinary mtDNA, IL-17A, IL-18, TNFα, ICAM-1, UACR, synaptopodin, podocalyxin, KIM-1, NAG, and indirect correlations with serum mtDNA, IL-10. BHI correlated directly with serum IL-10, and serum mtDNA, and negatively with serum IL-17A, serum ICAM-1, and NAG. In neurologically asymptomatic patients with type 2 DM cerebrovascular remodeling and impaired cerebrovascular reactivity may be associated with mtDNA variations and inflammation from the early stages of diabetic kidney disease.

Abstract
Acetaminophen and ibuprofen are widely used over-the-counter medications to reduce fever, pain, and inflammation. Although both drugs are safe in therapeutic concentrations, self-medication is practiced by millions of aged patients with comorbidities that decrease drug metabolism and/or excretion, thus raising the risk of overdosage. Mitochondrial dysfunction has emerged as an important pathomechanism underlying the organ toxicity of both drugs. Assessment of mitochondrial oxygen consumption in peripheral blood cells is a novel research field Cu several applications, including characterization of drug toxicity. The present study, conducted in human platelets isolated from blood donor-derived buffy coat, was aimed at assessing the acute, concentration-dependent effects of each drug on mitochondrial respiration. Using the high-resolution respirometry technique, a concentration-dependent decrease of oxygen consumption in both intact and permeabilized platelets was found for either drug, mainly by inhibiting complex I-supported active respiration. Moreover, ibuprofen significantly decreased the maximal capacity of the electron transport system already from the lowest concentration. In conclusion, platelets from healthy donors represents a population of cells easily available, which can be routinely used in studies assessing mitochondrial drug toxicity. Whether these results can be recapitulated in patients treated with these medications is worth further investigation as potential peripheral biomarker of drug overdose.

Abstract
Mitochondrial dysfunction is an important mechanism contributing to the development and progression of diabetic kidney disease (DKD). Mitochondrial DNA (mtDNA) levels in blood and urine were evaluated in relation to podocyte injury and proximal tubule (PT) dysfunction, as well as to a specific inflammatory response in normoalbuminuric DKD. A total of 150 type 2 diabetes mellitus (DM) patients (52 normoalbuminuric, 48 microalbuminuric, and 50 macroalbuminuric ones, respectively) and 30 healthy controls were assessed concerning the urinary albumin/creatinine ratio (UACR), biomarkers of podocyte damage (synaptopodin and podocalyxin), PT dysfunction (kidney injury molecule-1 (KIM-1) and N-acetyl-β-(D)-glucosaminidase (NAG)), and inflammation (serum and urinary interleukins (IL-17A, IL-18, and IL-10)). MtDNA-CN and nuclear DNA (nDNA) were quantified in peripheral blood and urine via qRT-PCR. MtDNA-CN was defined as the ratio of the number of mtDNA/nDNA copies via analysis of the CYTB/B2M and ND2/B2M ratio. Multivariable regression analysis provided models in which serum mtDNA directly correlated with IL-10 and indirectly correlated with UACR, IL-17A, and KIM-1 (R2 = 0.626; p < 0.0001). Urinary mtDNA directly correlated with UACR, podocalyxin, IL-18, and NAG, and negatively correlated with eGFR and IL-10 (R2 = 0.631; p < 0.0001). Mitochondrial DNA changes in serum and urine display a specific signature in relation to inflammation both at the podocyte and tubular levels in normoalbuminuric type 2 DM patients.

Abstract
Mitochondrial dysfunction has emerged as a central pathomechanism in the setting of obesity and diabetes mellitus, linking these intertwined pathologies that share insulin resistance as a common denominator. High-resolution respirometry (HRR) is a state-of-the-art research method currently used to study mitochondrial respiration and its impairment in health and disease. Tissue samples, cells or isolated mitochondria are exposed to various substrate-uncoupler-inhibitor-titration protocols, which allows the measurement and calculation of several parameters of mitochondrial respiration. In this review, we discuss the alterations of mitochondrial bioenergetics in the main dysfunctional organs that contribute to the development of the obese and diabetic phenotypes in both animal models and human subjects. Herein we review data regarding the impairment of oxidative phosphorylation as integrated mitochondrial function assessed by means of HRR. We acknowledge the critical role of this method in determining the alterations in oxidative phosphorylation occurring in the early stages of metabolic pathologies. We conclude that there is a mutual two-way relationship between mitochondrial dysfunction and insulin insensitivity that characterizes these diseases.

Type of funding sources: None.
Background. Reactive oxygen species (ROS) have been reported to contribute to the molecular pathogenesis of severe mitral regurgitation induced by myxomatous degeneration. Data about oxidative stress and the possible relationship with the extent of prolapsing and/or flail elements is scarce in the literature. The pathogenic mechanism may prompt the development of therapeutic approaches aimed at delaying extensive valvular alteration.
Purpose. The aim of the study is to investigate the possible correlation between ROS expression in myxomatous mitral valves with severe regurgitation and the extent of valvular alteration.
Material and methods. Samples from myxomatous mitral valves with ruptured chordae and severe regurgitation were harvested during surgical intervention for valve repair/replacement from 9 patients. Besides transthoracic echocardiography, all patients were evaluated before surgery by transesophageal echocardiography (TEE) with three-dimensional (3D) reconstruction of the mitral valve, using 3D zoom mode acquisition with qualitative and quantitative analysis through the 4D Auto MVQ technology. Tissue from the valvular samples was further analysed for the assessment of ROS by 2 methods: spectrophotometry (ferrous oxidation xylenol orange - FOX assay) and confocal microscopy (dihydroethidium staining).
Results. Patients had a mean age of 51.88 ± 13.54 years, with a left ventricular ejection fraction of 62.55 ± 7.33%, left ventricular end-diastolic diameter of 5.4 ± 0.72cm and end-diastolic volume of 168.55 ± 62.57ml, a mitral annulus area of 17.91 ± 5.74 cm2 and a number of prolapsing/flail scallops varying between 1 and 5 (average of 2 ± 1 scallops). All patients had diffuse thickening of the mitral leaflets with at least one primary and one secondary ruptured chordae and flail of the P2 scallop. Two patients had significant prolapse of at least 2 anterior mitral leaflet scallops and three patients had supplemental significant prolapse and/or flail of at least 1 posterior scallop, besides flail of P2. The mean value for ROS in the valvular tissue was 9.46 ± 2.03nM H2O2/mg tissue/h at FOX assay. A significant positive correlation between the ROS values and the extent of prolapsing/flail segments was found (R = 0.67, p = 0.04).
Conclusion. Besides the diagnosis and accurate preoperatory valve description, 3D TEE along with molecular investigations contribute to the understanding of myxomatous mitral valves’ pathogenesis. Oxidative stress increased in the mitral valves with advanced myxomatous degeneration. Whether this occurs as a cause or a consequence contributing to the disease progression as well as the sources of ROS are worth further investigation.

Abstract
Caloric restriction (CR) and intermittent fasting (IF) are strategies aimed to promote health beneficial effects by interfering with several mechanisms responsible for cardiovascular diseases. Both dietary approaches decrease body weight, insulin resistance, blood pressure, lipids, and inflammatory status. All these favorable effects are the result of several metabolic adjustments, which have been addressed in this review, i.e., the improvement of mitochondrial biogenesis, the reduction of reactive oxygen species (ROS) production, and the improvement of cardiac and vascular function. CR and IF are able to modulate mitochondrial function via interference with dynamics (i.e., fusion and fission), respiration, and related oxidative stress. In the cardiovascular system, both dietary interventions are able to improve endothelium-dependent relaxation, reduce cardiac hypertrophy, and activate antiapoptotic signaling cascades. Further clinical studies are required to assess the long-term safety in the clinical setting.

Abstract
Abstract
Background
Oxidative stress plays a central role in the pathogenesis of cardiovascular diseases but the role of enzymatic sources of reactive oxygen species (ROS) remains elusive. There is scarce information in the literature regarding valvular oxidative stress. Monoamine oxidases (MAOs), with 2 isoforms, A and B, have emerged as important sources of oxidative stress in the cardiovascular system.
Purpose
To assess whether MAOs-related oxidative stress occurs in the pathological valves in patients with severe mitral regurgitation (due to valve degeneration and chordae rupture) and surgical indication and its interference with the activation of the renin-angiotensin aldosterone (RAAS) system.
Material and methods
Samples of mitral valve (n=17) were harvested during the valvular replacement procedure and used for reactive oxygen species (ROS) assessment (immune-fluorescence, spectrophotometry) and MAO mRNA and protein expression (qPCR and immune-fluorescence) measurement. Inflammatory markers, biochemical parameters and echocardiography (GE, Vivid 9, Vivid E95) data were also collected.
Results
Both MAO isoforms are expressed in the diseased mitral valves, with a predominance of MAO-A isoform. Ex vivo incubation with angiotensin 2 (12 h, 100 nM) of samples obtained from patients without RAAS medication lead to MAO upregulation and high ROS production. MAO-related oxidative stress was mitigated by MAO inhibition with clorgyline (MAO-A inhibitor, 10 microM) and selegyline (MAO-B inhibitor, 10 microM) and also by the angiotensin II receptor type 1 (AT1) antagonist, irbersartan (10 microM).
Conclusions
Monoamine oxidase is expressed in the pathological mitral valves, regardless the etiology. Its expression and the related-oxidative stress are modulated by angiotensin 2, irbesartan. Whether the latter effect is present in valvular patients treated with RAAS inhibitors is currently under investigation.

Abstract
Maslinic acid is a pentacyclic triterpene with a plethora of biological activities, including anti-inflammatory, antioxidant, antimicrobial, cardioprotective, and antitumor effects. New derivatives with improved properties and broad-spectrum activity can be obtained following structural changes of the compound. The present study was aimed to characterize a benzylamide derivative of maslinic acid—benzyl (2α, 3β) 2,3-diacetoxy-olean−12-en-28-amide (EM2)—with respect to the anti-angiogenic and anti-inflammatory effects in two in vivo experimental models. Consequently, the compound showed good tolerability and lack of irritation in the chorioallantoic membrane assay with no impairment of the normal angiogenic process during the tested stages of development. In the acute ear inflammation murine model, application of EM2 induced a mild anti-inflammatory effect that was potentiated by the association with zinc chloride (ZnCl2). A decrease in dermal thickness of mice ears was observed when EM2 and ZnCl2 were applied separately or in combination. Moreover, hyalinization of the dermis appeared only when EM2 was associated with ZnCl2, strongly suggesting the role of their combination in wound healing.

Abstract
Mitochondrial dysfunction is currently acknowledged as a central pathomechanism of most common diseases of the 21(st) century. Recently, the assessment of the bioenergetic profile of human peripheral blood cells has emerged as a novel research field with potential applications in the development of disease biomarkers. In particular, platelets have been successfully used for the ex vivo analysis of mitochondrial respiratory function in several acute and chronic pathologies. An increasing number of studies support the idea that evaluation of the bioenergetic function in circulating platelets may represent the peripheral signature of mitochondrial dysfunction in metabolically active tissues (brain, heart, liver, skeletal muscle). Accordingly, impairment of mitochondrial respiration in peripheral platelets might have potential clinical applicability as a diagnostic and prognostic tool as well as a biomarker in treatment monitoring. The aim of this minireview is to summarize current information in the field of platelet mitochondrial dysfunction in both acute and chronic diseases.

A new rapid high-throughput liquid chromatography coupled with tandem mass spectrometry method (LC-MS/MS) was developed for the blood assessment of a maslinic acid derivative (Benzyl (2a, 3b) 2,3-diacetoxy-olean-12-en-28-amide) and its metabolite. Separation was performed using a Zorbax SB-C18 column with a mobile phase composition of methanol and 0.2% formic acid in water (78:22, v/v) in isocratic flow, with a flow rate of 0.6 mL/min. Detection was performed by multiple reaction monitoring (MRM) mode, monitoring the transitions 338.3; 526.6; 544.6; 527.5; 545.5 m/z derived from 646.6 m/z for the maslinic acid derivative and 409; 338.3; 203; 205; 526.5 m/z derived from 562.6 m/z for its metabolite, using atmospheric pressure chemical positive ionisation source. Single-step protein precipitation with methanol was used for preparation of rat blood samples. The method was validated with respect to selectivity, linearity (r ] 0.9937), within-run and between-run precision (CV [ 12.0%) and accuracy (bias [ 7.9%) over the ranges of 20.5 - 656 ng/mL blood for maslinic acid derivative, and 20 - 640 ng/mL blood for maslinic acid derivative metabolite. The analytical method is simple, fast, selective and is suitable for bioanalysis of maslinic acid derivative and its metabolite from rat blood.
