UN MODELLO EMPIRICO DI EMISSIONE DI CO2 DAL SUOLO: CURVE DI RISPOSTA ALLA TEMPERATURA ED ALL'UMIDITÀ DEL SUOLO DI UN AGROECOSISTEMA MEDITERRANEO
2012
Il presente lavoro è stato condotto su suolo prelevato all’interno di un oliveto con l’obiettivo di valutare il tasso di respirazione attribuibile alla componente eterotrofa (microbica) in funzione dei fattori temperatura ed umidità. Il tasso di respirazione è stato monitorato su suolo incubato a cinque livelli di temperatura, 10-15-20-25-30 °C e a quattro livelli del contenuto idrico volumetrico del suolo (θ) 12,6-18,9-25,2-31,5 % (v/v). I valori di respirazione hanno presentato un range di valori variabili tra 78,20 e 14,81 µg CO2 g-1 soil d-1 rispettivamente a 30°C e 10°C e a 12,6 e 31,5 %. I valori di Q10, ovvero la risposta della respirazione in relazione agli incrementi di temperatura…
An overview of statin-induced myopathy and perspectives for the future
2020
Introduction: Statins remain the most commonly prescribed lipid-lowering drug class for the treatment of atherosclerotic cardiovascular disease. Their well-recognized side effects are known as statin-associated muscle symptom (SAMS). Some advances in this field have been made in recent years, but the understanding of the mechanisms has lagged. Investigating the specific role of the anti-HMGCR autoantibody, pharmacokinetic genetic variants, characterization of the known phenotypes of statin toxicity, in relation to clinical markers of disease, is of high importance. Areas covered: We summarized currently available findings (on PubMed) related to SAMS and discussed the therapeutic approaches,…
Toward the definition of a carbon budget model: seasonal variation and temperature effect on respiration rate of vegetative and reproductive organs o…
2009
Summary This study, as a preliminary step toward the definition of a carbon budget model for pistachio trees (Pistacia vera L.), aimed at estimating and evaluating the dynamics of respiration of vegetative and reproductive organs of pistachio tree. Trials were performed in 2005 in a commercial orchard located in Sicily (370 m a.s.l.) on five bearing 20-year-old pistachio trees of cv. Bianca grafted onto Pistachio terebinthus L. Growth analyses and respiration measurements were done on vegetative (leaf) and reproductive (infructescence) organs during the entire growing season (April–September) at biweekly intervals. Results suggested that the respiration rates of pistachio reproductive and v…
Aging-Related Disorders and Mitochondrial Dysfunction: A Critical Review for Prospect Mitoprotective Strategies Based on Mitochondrial Nutrient Mixtu…
2020
A number of aging-related disorders (ARD) have been related to oxidative stress (OS) and mitochondrial dysfunction (MDF) in a well-established body of literature. Most studies focused on cardiovascular disorders (CVD), type 2 diabetes (T2D), and neurodegenerative disorders. Counteracting OS and MDF has been envisaged to improve the clinical management of ARD, and major roles have been assigned to three mitochondrial cofactors, also termed mitochondrial nutrients (MNs), i.e., alpha-lipoic acid (ALA), Coenzyme Q10 (CoQ10), and carnitine (CARN). These cofactors exert essential-and distinct-roles in mitochondrial machineries, along with strong antioxidant properties. Clinical trials have mostly…
Re-definition and supporting evidence toward Fanconi Anemia as a mitochondrial disease: Prospects for new design in clinical management
2021
Fanconi anemia (FA) has been investigated since early studies based on two definitions, namely defective DNA repair and proinflammatory condition. The former definition has built up the grounds for FA diagnosis as excess sensitivity of patients' cells to xenobiotics as diepoxybutane and mitomycin C, resulting in typical chromosomal abnormalities. Another line of studies has related FA phenotype to a prooxidant state, as detected by both in vitro and ex vivo studies. The discovery that the FA group G (FANCG) protein is found in mitochondria (Mukhopadhyay et al., 2006) has been followed by an extensive line of studies providing evidence for multiple links between other FA gene products and mi…
Effects of Coenzyme Q10 on Statin-Induced Myopathy
2015
Abstract Objective To evaluate the efficacy of coenzyme Q10 (CoQ10) supplementation on statin-induced myopathy. Participants and Methods We searched the MEDLINE, Cochrane Library, Scopus, and EMBASE databases (November 1, 1987, to May 1, 2014) to identify randomized controlled trials investigating the impact of CoQ10 on muscle pain and plasma creatine kinase (CK) activity as 2 measures of statin-induced myalgia. Two independent reviewers extracted data on study characteristics, methods, and outcomes. Results We included 6 studies with 302 patients receiving statin therapy: 5 studies with 226 participants evaluated the effect of CoQ10 supplementation on plasma CK activity, and 5 studies (4 u…
Diet supplementation during early lactation with non-alcoholic beer increases the antioxidant properties of breastmilk and decreases the oxidative da…
2013
After delivery and birth, mothers and neonates are exposed to oxidative stress. We tested whether supplementing the diet of breastfeeding mothers with non-alcoholic beer, a product rich in antioxidants, could improve their oxidative status and the antioxidant content of their milk. A prospective trial begun on Day 2 postpartum was conducted in mother-infant dyads.Sixty breastfeeding mothers and their infants were allocated to either a control group (n=30) on a free diet or a study group (n=30) on a free diet supplemented with 660 mL of non-alcoholic beer/day. The oxidative status of the mothers' breastmilk, plasma, and urine and the infant's urine was analyzed on Days 2 and 30 postpartum. T…
Statin therapy and plasma coenzyme Q10 concentrations—A systematic review and meta-analysis of placebo-controlled trials
2015
Statin therapy may lower plasma coenzyme Q10 (CoQ10) concentrations, but the evidence as to the significance of this effect is unclear. We assessed the impact of statin therapy on plasma CoQ10 concentrations through the meta-analysis of available RCTs. The literature search included selected databases up to April 30, 2015. The meta-analysis was performed using either a fixed-effects or random-effect model according to I(2) statistic. Effect sizes were expressed as weighted mean difference (WMD) and 95% confidence interval (CI). The data from 8 placebo-controlled treatment arms suggested a significant reduction in plasma CoQ10 concentrations following treatment with statins (WMD: -0.44 μmol/…
Friedreich Ataxia: current state-of-the-art, and future prospects for mitochondrial-focused therapies
2021
Friedreichs Ataxia is an autosomal recessive genetic disease causing the defective gene product, frataxin. A body of literature has been focused on the attempts to counteract frataxin deficiency and the consequent iron imbalance, in order to mitigate the disease-associated prooxidant state and clinical course. The present mini review is aimed at evaluating the basic and clinical reports on the roles and the use of a set of iron chelators, antioxidants and some cofactors involved in the key mitochondrial functions. Extensive literature has focused on the protective roles of iron chelators, coenzyme Q10 and analogs, and vitamin E, altogether with varying outcomes in clinical studies. Other st…
Pilot study of safety and efficacy of polyprenols in combination with coenzyme Q10 in patients with statin-induced myopathy
2016
Background and objective: Statin-induced myopathy (SIM) has been partially attributed to deficiency of dolichol and coenzyme Q10 (CoQ10). We aimed to test the safety and efficacy of plant polyprenols in combination with CoQ10 for alleviation of SIM. Materials and methods: In an open-label, one-center prospective pilot study patients with SIM received conifer-tree needle polyprenols (4 mg/day) and CoQ10 (100 mg/day) for 8 weeks. Symptoms and safety were evaluated according to symptom severity score (0–10), creatine kinase (CK) levels, exercise test, dynamometry, complete blood count, clinical biochemistry and electrocardiography. Results: Of the 14 patients, 11 completed the study per protoc…
