Abstract
The characterization of the microbial population of many niches of the organism, as the gastrointestinal tract, is now possible thanks to the use of high-throughput DNA sequencing technique. Several studies in the companion animals field already investigated faecal microbiome in healthy or affected subjects, although the methodologies used in the different laboratories and the limited number of animals recruited in each experiment does not allow a straight comparison among published results. In the present study, we report data collected from several in house researches carried out in healthy dogs, with the aim to seek for a variability of microbial taxa in the faeces, caused by factors such as diet and sex. The database contains 340 samples from 132 dogs, collected serially during dietary intervention studies. The procedure of samples collection, storage, DNA extraction and sequencing, bioinformatic and statistical analysis followed a standardized pipeline. Microbial profiles of faecal samples have been analyzed applying dimensional reduction discriminant analysis followed by random forest analysis to the relative abundances of genera in the feces as variables. The results supported the responsiveness of microbiota at a genera taxonomic level to dietary factor and allowed to cluster dogs according this factor with high accuracy. Also sex factor clustered dogs, with castrated males and spayed females forming a separated group in comparison to intact dogs, strengthening the hypothesis of a bidirectional interaction between microbiota and endocrine status of the host. The findings of the present analysis are promising for a better comprehension of the mechanisms that regulate the connection of the microorganisms living the gastrointestinal tract with the diet and the host. This preliminary study deserves further investigation for the identification of the factors affecting faecal microbiome in dogs.

Abstract
Several studies have underlined the interplay among host-microbiome and pathophysiological conditions of animals. Research has also focused specifically on whether and how changes in the gut microbiome have provoked the occurrence of pathological phenomena affecting cartilage and joints in humans and in laboratory animals. Here, we tried to evaluate the relationship between the gut microbiome and the hip and elbow arthritis in owned dogs. The study included 14 dogs suffering from chronic arthritis (AD) and 13 healthy dogs (HD). After the first visit and during the period of the study, the dogs, under the supervision of the owner, were fed a semi-moist complete diet supplemented with omega 3 fatty acids. Feces and blood samples were collected in the clinic at the first visit (T0) and after days (T45). The plasma C-reactive protein (CRP) was higher, and the serum vitamin B12 and folate concentrations were lower (p < 0.05) in the AD group in comparison to the HD group. Data of the fecal microbiome showed that the relative abundances of the genus Megamonas were higher in AD (p < 0.001), while the relative abundance of the families Paraprevotellaceae, Porphyromonadaceae, and Mogibacteriaceae was significantly lower in comparison to HD. The results of the study identified several bacterial groups that differed significantly in the fecal microbiome between healthy and diseased dogs. If the observed differences in fecal bacterial composition predispose dogs to hip and elbow arthritis or if these differences reflect a correlation with these conditions deserves further investigation.

Abstract
A dietary intervention study was assessed to determine if different sources of starch in homemade diets could significantly modify fecal microbiome of dogs. Twenty-seven adult dogs were enrolled and fed a diet based on a mixture of rice and pasta with fresh raw meat (CD). After 90 d, 8 dogs continued to receive CD diet, 10 dogs received a diet made of a raw meat and a complementary food with rice as the main source of starch (B1), and 9 dogs were fed a diet with the same raw meat and a complementary food with potato as the main source of starch (B2). Samples of feces were collected from each dog in the mornings at the beginning of the study and after 15 d and analyzed for pH, ammonia N (N–NH3) and total N, short chain fatty acids (SCFA) and lactic acid. Relative abundance of fecal microbiota was assessed by sequencing and annotating the V3–V4 regions of the 16S rRNA. Total starch intake was similar between diets but differed in the in vitro rate digestion and in the resistant starch, which was higher in B2 than in B1 and CD diets. Dogs fed B2 diet showed lower (P < 0.05) N–NH3 and pH but higher (P < 0.05) molar proportion of lactic acid. Linear discriminant analysis of the genera relative abundances indicated a significant (P < 0.01) increase of SMB53 genus at the end of the study in B1 diet and of Megamonas genus in B1 and B2 diets in comparison to CD diet. These results suggest that changes of starch source in a raw meat-based diet have limited effects on fecal microbiome in healthy dogs, but underline a high variability of microbiota among dogs.

Abstract
Abstract
Purpose
Recent studies and our preliminary data demonstrate that muscle-specific ablation of the autophagy-related protein Atg7, leads to block of autophagy, sarcopenia and destabilization of the neuro-muscular junction (NMJ). In addition, Atg7 knock-out (Atg7 KO) muscle fibers release exosomes containing the muscle specific, miR-206, which is consistently elevated in the plasma. Interestingly, we found that miR-206 content was elevated in the heart, suggesting cardiac uptake of the miR-carrying circulating exosomes. We thus aimed at defining the effects of miR-206 on heart homeostasis.
Methods
Here, we analyzed the cardiac phenotype of adult (12mo.) and aged (24mo.) Atg7 KO mice, as well as of adult C57BL/6J mice injected, via tail vein, with scramble- or miR-206-loaded exosomes. Exosomes were isolated from EDL muscle of control and Atg7 KO mice, as well as from HEK293 cells. Heart function was assessed by echocardiography and ECG-telemetry. Confocal IF, whole-mount IF on heart blocks and multiphoton imaging were used to assess heart structure and sympathetic innervation. Bioinformatics, molecular and biochemical analyses were performed to identify novel targets of miR-206. IF, BRET assay and imaging of TrKA translocation were performed in cultured sympathetic neurons (SNs).
Results
We demonstrate that circulating exosomes, containing miR-206, are taken up by the heart leading to sympathetic dysinnervation, accompanied to reduction in the neurogenic control of cardiac rhythm and increased arrhythmogenesis. In vitro assays demonstrated that exosome-carried miR-206 targets cardiac SNs (cSNs), compromising cell structure and function. Indeed, increased miR-206 expression is accompanied by cSN atrophy, irregular axonal distribution of the active neurotransmitter release sites, and reduction in axonal sprouting. These effects are likely attributed to the miR-206-mediated down-regulation of the NGF receptor p75, as demonstrated by bioinformatics, luciferase assay, molecular and biochemical analyses in vitro and ex vivo. BRET assay, performed in cultured SNs treated with exosomes carrying miR-206, showed reduced formation of p75/TrkA complexes, which generate high-affinity binding sites for NGF and enhance neurotrophin responsiveness. Consistent with impaired NGF retrograde transport, miR-206 over-expressing SNs displayed reduced NGF protein content and decreased phosphorylation of Akt, which is an NGF downstream target, regulating neuronal survival. Interestingly, these latter results were confirmed in the stellate ganglia from Atg KO and miR-206 treated mice.
miR-206 causes heart dysinnervation
Conclusions
We identify miR-206 as a key molecular player in the “muscle-to-heart” communication. miR-206 may participate to the pathogenesis of secondary cardiac dysfunction in skeletal muscle diseases associated to increased circulating levels of miR-206, ranging from ageing to neurodegenerative disorders (i.e. ALS, DMD).

Abstract
Abstract
Background
The majority of patients presenting with myocardial infarction (MI) and cardiogenic shock (CS) have multivessel coronary artery disease. The prognosis impact of the SYNTAX score (SS) in this setting remains unknown.
Purpose
To evaluate the prognosis value of the SS in this high-risk population undergoing percutaneous coronary intervention (PCI)
Methods
The CULPRIT-SHOCK trial was an international, open-label trial, where patients presenting with MI and multivessel disease complicated by CS were randomized to a culprit-lesion-only or an immediate multivessel PCI strategy. Pre-PCI SS was assessed by a central core laboratory and patients were categorized as low SS (SS ≤22), intermediate SS (22<SS≤32) and high SS (SS>32). Adjudicated endpoints of interest were the risks of all-cause death or renal replacement therapy at 30 days and all-cause death at 1 year. Associations between SYNTAX score and outcomes were assessed using multivariate logistic regression.
Results
SS was available in 632 patients, of whom 265 (41.9%), 211 (33.4%) and 156 (24.7%) presented with low, intermediate and high SS, respectively. Patients with higher SS were older, with more frequent peripheral artery disease, less current smoking, lower creatinine clearance, and higher use of catecholamine. A stepwise increase in the incidence of adverse events transitioning from low to intermediate and high SS was observed with the 30-day risk of death or renal replacement therapy as well as the 1-year risk of all-cause death (p for trend <0.001, for all). After multiple adjustment, intermediate and high SS remained strongly associated with 30-day risk of death and renal replacement therapy and 1-year risk of all-cause death (Figure). There was no significant interaction between SYNTAX score and the coronary revascularization strategy for all endpoints.
Conclusion
In patients presenting with acute MI, multivessel disease and CS, the SYNTAX score was strongly associated to 30-day and 1-year mortality</ss≤<ss≤32)>

Abstract
Autophagy is active during cellular remodeling including muscle differentiation. Muscle differentiation is dysregulated in type 2 diabetes and we therefore hypothesize that muscle precursor cells from people with type 2 diabetes (T2DM) have a dysregulation of their autophagy leading to impaired myogenesis. Muscle precursor cells were isolated from people with T2DM or healthy controls and differentiated in vitro. Autophagy marker levels were assessed by immunoblotting. Differentially expressed autophagy-related genes between healthy and T2DM groups were identified based on a previously published RNA-sequencing data-set, which we verified by RT-qPCR. siRNA was used to assess the function of differentially expressed autophagy genes. Basal autophagy increases during human muscle differentiation, while T2DM muscle cells have reduced levels of autophagy marker ATG7 and show a blunted response to starvation. Moreover, we demonstrate that the 3 non-canonical autophagy genes DRAM1, VAMP8 and TP53INP1 as differentially expressed between healthy and T2DM groups during myoblast differentiation, and that T53INP1 knock-down alters expression of both pro-and anti-apoptotic genes. In vitro differentiated T2DM muscle cells show differential expression of autophagy-related genes. These genes do not regulate myogenic transcription factors but may rather be involved in p53-associated myoblast apoptosis during early myogenesis.

Abstract
The long-term use of Cu-containing fungicides contaminates vineyards soils, which can induce Cu toxicity and nutrient imbalances in several plant species. The aim of this work was to evaluate the effect of Cu toxicity on two grapevine rootstocks, Fercal and 196.17, and to elucidate if intercropping with oat can alleviate grapevine Cu toxicity. Plants were hydroponically-cultivated and treated with different Cu concentrations. At harvest the biomass accumulation, the SPAD index and the symplastic and apoplastic root and leaves ionome were measured to evaluate possible synergistic and/or antagonistic effects on other micro- and macronutrients. The root exudation analysis was correlated with genes expression (VvPEZ-like), whereas PCA analysis performed on the grapevine and oat ionome revealed that both mono- and intercropped 196.17 rootstock display a positive effect on Zn and Mn in the root tissues at high Cu concentrations. An increase of Zn and Mn in roots was also reported for the intercropped Fercal rootstock at high Cu concentrations while an antagonistic relation was reported for root Zn concentration in the monocropped Fercal rootstock. Our results showed that grapevine and oat compete for nutrient uptake and that this phenomenon can possibly alleviate grapevine Cu toxicity. However, Fercal rootstock is able to take advantage from oat, while 196.17 is disadvantaged by the intercropping system. Even though intercropping system seems to be a valuable tool to counteract grapevine Cu toxicity, the application of this agricultural practice has shown to be species dependent and should be evaluated for each rootstock.

Abstract
BACKGROUND Recent studies have highlighted the possible involvement of leptin in inflammation. The leptin receptor is also expressed by alveolar macrophages, T lymphocytes and bronchial epitelial cells, suggesting a possible role in the cascade of airway inflammation. OBJECTIVES The aim of the study was to evaluate the levels of leptin in exhaled breath condensate (EBC) from asthmatic, normal- and overweight children, in relationship with airway inflammation. METHODS 15 asthmatic non-obese children, 15 healthy non-asthmatic non-obese children, 11 obese children with asthma (OA) and 20 obese children without asthma (ONA) were enrolled. Body impedance of body weight, EBC collection, FeNO, spirometry and a blood sampling for serum leptin were assessed. RESULTS Leptin EBC levels were significantly higher (3.9 ng ml-1 ± 1.3) in overweight children than those obese with asthma (3.6 ng ml-1 ± 1.6; p = 0.97), non-owerweight asthmatics (2.2 ng ml-1 ± 1.2; p < 0.0001) and in healthy children (0.9 ng ml-1 ± 0.6; p < 0.001). Leptin EBC levels in asthmatic children were significantly higher than in healthy children (p = 0.05). Leptin serum levels were significantly higher in the overweight children compared with the asthmatics (12.7 ng ml-1 ± 13.2; p < 0.001) and the healthy group (11.1 ng ml-1 ± 11.2; p < 0.001). We observed a significant correlation between EBC-leptin levels and the serum-leptin levels (p = 0.001). No correlations were found between EBC-leptin levels, FeNO and lung function. CONCLUSIONS This study shows that leptin is measurable in EBC in children and that EBC-leptin levels are significantly higher in the obese subjects and in asthmatic ones compared with healthy subjects. Leptin may therefore represent a non-invasive marker of non-specific airway inflammation in children.
