Abstract
Five-year glioblastoma (GBM) survivors (LTS) are the minority of the isocitrate dehydrogenase (IDH)-wild-type GBM patients, and their molecular fingerprint is still largely unexplored. This multicenter retrospective study analyzed a large LTS-GBM cohort from nine Italian institutions and molecularly characterized a subgroup of patients by mutation, DNA methylation (DNAm) and copy number variation (CNV) profiling, comparing it to standard survival GBM. Mutation scan allowed the identification of pathogenic variants in most cases, showing a similar mutational spectrum in both groups, and highlighted TP53 as the most commonly mutated gene in the LTS group. We confirmed DNAm as a valuable tool for GBM classification with a diagnostic refinement by using brain tumor classifier v12.5. LTS were more heterogeneous with more cases classified as diffuse pediatric high-grade glioma subtypes and having peculiar CNVs. We observed a global higher methylation in CpG islands and in gene promoters of LTS with methylation levels of distinct gene promoters correlating with prognosis.

Abstract
BACKGROUND Genetic and metabolic heterogeneity are well-known features of cancer and tumors can be viewed as an evolving mix of subclonal populations, subjected to selection driven by microenvironmental pressures or drug treatment. In previous studies, anti-VEGF therapy was found to elicit rewiring of tumor metabolism, causing marked alterations in glucose, lactate ad ATP levels in tumors. The aim of this study was to evaluate whether differences in the sensitivity to glucose starvation existed at the clonal level in ovarian cancer cells and to investigate the effects induced by anti-VEGF therapy on this phenotype by multi-omics analysis. METHODS Clonal populations, obtained from both ovarian cancer cell lines (IGROV-1 and SKOV3) and tumor xenografts upon glucose deprivation, were defined as glucose deprivation resistant (GDR) or glucose deprivation sensitive (GDS) clones based on their in vitro behaviour. GDR and GDS clones were characterized using a multi-omics approach, including genetic, transcriptomic and metabolic analysis, and tested for their tumorigenic potential and reaction to anti-angiogenic therapy. RESULTS Two clonal populations, GDR and GDS, with strikingly different viability following in vitro glucose starvation, were identified in ovarian cancer cell lines. GDR clones survived and overcame glucose starvation-induced stress by enhancing mitochondrial oxidative phosphorylation (OXPHOS) and both pyruvate and lipids uptake, whereas GDS clones were less able to adapt and died. Treatment of ovarian cancer xenografts with the anti-VEGF drug bevacizumab positively selected for GDR clones that disclosed increased tumorigenic properties in NOD/SCID mice. Remarkably, GDR clones were more sensitive than GDS clones to the mitochondrial respiratory chain complex I inhibitor metformin, thus suggesting a potential therapeutic strategy to target the OXPHOS-metabolic dependency of this subpopulation. CONCLUSION A glucose-deprivation resistant population of ovarian cancer cells showing druggable OXPHOS-dependent metabolic traits is enriched in experimental tumors treated by anti-VEGF therapy.

Abstract
PURPOSE Patient-derived cancer cell lines can be very useful to investigate genetic as well as epigenetic mechanisms of transformation and to test new drugs. In this multi-centric study, we performed genomic and transcriptomic characterization of a large set of patient-derived glioblastoma (GBM) stem-like cells (GSCs). METHODS 94 (80 I surgery/14 II surgery) and 53 (42 I surgery/11 II surgery) GSCs lines underwent whole exome and trascriptome analysis, respectively. RESULTS Exome sequencing revealed TP53 as the main mutated gene (41/94 samples, 44%), followed by PTEN (33/94, 35%), RB1 (16/94, 17%) and NF1 (15/94, 16%), among other genes associated to brain tumors. One GSC sample bearing a BRAF p.V600E mutation showed sensitivity in vitro to a BRAF inhibitor. Gene Ontology and Reactome analysis uncovered several biological processes mostly associated to gliogenesis and glial cell differentiation, S - adenosylmethionine metabolic process, mismatch repair and methylation. Comparison of I and II surgery samples disclosed a similar distribution of mutated genes, with an overrepresentation of mutations in mismatch repair, cell cycle, p53 and methylation pathways in I surgery samples, and of mutations in receptor tyrosine kinase and MAPK signaling pathways in II surgery samples. Unsupervised hierarchical clustering of RNA-seq data produced 3 clusters characterized by distinctive sets of up-regulated genes and signaling pathways. CONCLUSION The availability of a large set of fully molecularly characterized GCSs represents a valuable public resource to support the advancement of precision oncology for the treatment of GBM.

Abstract
PURPOSE Current glioma diagnostic guidelines call for molecular profiling to stratify patients into prognostic and treatment subgroups. In case the tumor tissue is inaccessible, cerebrospinal fluid (CSF) has been proposed as a reliable tumor DNA source for liquid biopsy. We prospectively investigated the use of CSF for molecular characterization of newly diagnosed gliomas. EXPERIMENTAL DESIGN We recruited two cohorts of newly diagnosed glioma patients, one (n=45) providing CSF collected in proximity of the tumor, the other (n=39) CSF collected by lumbar puncture. Both cohorts provided tumor tissues by surgery concomitant with CSF sampling. DNA samples retrieved from CSF and matched tumors were systematically characterized and compared by comprehensive (NGS) or targeted (ddPCR) methodologies. Conventional and molecular diagnosis outcomes were compared. RESULTS We report that tumor DNA is abundant in CSF close to the tumor, but scanty and mostly below NGS sensitivity threshold in CSF from lumbar puncture. Indeed, tumor DNA is 15 mostly released by cells invading liquoral spaces, generating a gradient that attenuates by departing from the tumor. Nevertheless, in >60% of lumbar puncture CSF samples, tumor DNA is sufficient to assess a selected panel of genetic alterations (IDH and TERT promoter mutations, EGFR amplification, CDKN2A/B deletion: ITEC protocol) and MGMT methylation that, combined with imaging, enable tissue-agnostic identification of main glioma molecular subtypes. CONCLUSIONS This study shows potentialities and limitations of CSF liquid biopsy in achieving molecular characterization of gliomas at first clinical presentation and proposes a protocol to maximize diagnostic information retrievable from CSF DNA.

Abstract
Glioblastoma multiforme (GBM) has a dismal outcome of approximately 12 months. Less than 5% of patients (long-term survivors-LTS) survives more than 5-years, including IDH-mutant gliomas. Nevertheless, the molecular fingerprint of LTS remains largely uncharted. DNA methylation (DNAm) is an epigenetic modification, altered in cancer and used to classify brain tumors. In this multicentric study sponsored by Alleanza Contro il Cancro (ACC) network, we aimed to molecularly characterize LTS vs standard survival GBM (CTR) by DNAm/Copy Number Variation (CNV) and mutation profiling. We analyzed 51 IDHwt GBM samples (27LTS/24CTR) by Illumina EPIC beadChip and AmpliSeq Comprehensive Cancer Panel. We ran methylation data through the brain tumor classifiers v11b4 and v12.5, performed multidimensional scaling analysis and investigated differentially methylated regions (DMR) correlating them with survival. According to v11b4, cases were classified as: 43 GBM IDHwt (22LTS/21CTR), 27 with a calibrated score >0.84 (16LTS); Plexus Tumor with low scores (2LTS/3CTR); 3 LTS samples did not match. A diagnostic refinement was observed by the v12.5, with 48 cases classifying as GBM IDHwt (25LTS/23CTR) and 35 (19LTS) with optimal score. The LTS group was more heterogeneous, with 4 cases matching in the pedHGG subtypes, including 2 cases in young adults, one with high tumor mutational burden and MSH6 mutation. No specific DNAm genomic profile was observed for LTS patients but we identified 18 significant DMRs, 4 associated with survival probability. At CNV analysis, most cases showed classical alterations (Chr7 gain with or w/o EGFR amplification, 9p21 loss, Chr10 loss) while pedHGG were associated with PDGFRA amplification, 1q gain, 13q loss. NGS identified at least 1 pathogenic variant in 40 cases (22CTR/18LTS) and showed a higher prevalence of mutation negative cases among LTS. No significant difference between the 2 groups was observed in terms of prevalence of mutated genes or number of VUS per sample.

Background
Ageing of cardiomyocytes (CM) involves structural and functional adverse remodelling that finally could result in heart failure (HF) insurgence, which incidence rise along with age (1). Current medical therapies for HF may not always be tolerated in elder patients(2). Having shown that cardiac progenitor cells (CPCs) secrete nanoparticles named exosomes (EXO) enriched of cardioprotective factors(3,4), we are exploring EXO’s capacity to ameliorate senescence-derived modification into CMs. However, human models of in vitro cardiac aging are currently missing(5).
Aim
This study exploits CMs derived from human induced pluripotent stem cells (hiPSCs) as an in vitro model for cardiac senescence, that will be used as platform to characterize mechanisms involved in cardiac ageing and to test protective effect of CPC-derived EXO.
Methods
Patient-derived CPCs were reprogrammed into hiPSCs and subsequently expanded and differentiated into cardiomyocytes (hiPSC-CMs). Senescence-like phenotype was induced by short exposure (3 hours) to doxorubicin (DOX) at sub-lethal concentration (0.2 µM), followed by washing and medium change. Following DOX exposure, cells were exposed to EXO, derived from the purification of conditioned culture media of CPCs using an ultracentrifugation-based isolation method and quantified and sized using a NTA counter. Senescence induction was highlighted by protein and gene expression analysis and senescence-associated b-galactosidase (SA-β-gal) assay.Electrical activity of hiPSC-CMs was evaluated recording extracellular field potentials through multi-microelectrode arrays (MEA) and by single cell patch clamp. Metabolic features were analysed with western blot, real time RT-PCR and specific biochemical assays.
Results
DOX treatment in hiPSC-CMs induced senescence, as confirmed by activation of p21 and p16 pathways and increasing of SA-β-gal staining as compared to untreated cells (CTR). Biochemical and gene expression analysis revealed an increased ROS production and a reduction in mitochondrial potential, which drives a strong decrease in the ATP/AMP ratios. Real Time PCR analysis reveal an increased transcription of molecules related to the senescence associated secretory phenotype in DOX-CMs. Moreover, DOX-CMs showed impaired Ca++ handling, prolonged multicellular QTc and single cell APD, with increased APD variability and delayed afterdepolarizations (DADs) incidence in comparison to CTR.
EXO treatment mitigated the senescent phenotype induced by DOX, as shown by a decreased ROS induction, higher mitochondrial potential which drives a restored ATP/AMP ratio. Furthermore, DOX-induced QTc prolongation was prevented by EXO treatment.
Conclusion
Our hiPSC-CMs based cellular model recapitulates the phenotype of aged CMs in terms of senescence markers, electrical and metabolic proprieties. CPC-derived EXOs limit age-related modifications, highlighting the cardioprotective role of small molecules released by EXO.

Abstract
This study investigated the perioperative effects of preemptive intra-articular lidocaine (L group), dexmedetomidine (D group) and lidocaine-dexmedetomidine (LD group) in dogs. Physiological variables were intraoperatively recorded at 5 min intervals starting from baseline (5 min before intra-articular injection). If nociception occurred, IV fentanyl was administered. Postoperative pain was assessed using the Short Form-Glasgow Composite Measure Pain Scale. Twenty-four dogs (eight in each group) were included in this prospective, randomized, masked clinical study. In the LD group, systolic arterial pressure significantly increased at T10 (P = 0.027), T15 (P = 0.021) and T20 (P = 0.022), compared with baseline. In the D and LD groups, mean arterial pressure significantly increased at T10 (P = 0.022; 0.024), T15 (P = 0.024; 0.09) and T20 (P = 0.019; 0.021), compared with baseline and diastolic arterial pressure significantly increased at T10 (P = 0.026; 0.047), T15 (P = 0.021; 0.023), T20 (P = 0.011; 0.012) and T25 (P = 0.019; 0.027), compared with baseline. In the LD group, heart rate significantly decreased at T5 (P = 0.031), T10 (P = 0.026) and T15 (P = 0.034), compared with baseline. Atrioventricular blocks appeared more frequently in the LD group than in L and D groups (P = 0.002). Group L received more fentanyl than the D and LD groups (P = 0.03). No differences in postoperative pain score were detected (P = 0.121). These findings suggested systemic absorption of intra-articular dexmedetomidine. Intra-articular lidocaine-dexmedetomidine was associated with a greater incidence of atrioventricular blocks. Intra-articular dexmedetomidine, alone and combined with lidocaine, provided better intraoperative analgesia than lidocaine in dogs undergoing arthroscopy, although the 12 h postoperative analgesic effect of the three treatments was similar.

Abstract
Sphingolipids are structural components of cell membrane, displaying several functions in cell signalling. Extracellular vesicles (EV) are lipid bilayer membrane nanoparticle and their lipid composition may be different from parental cells, with a significant enrichment in sphingolipid species, especially in pathological conditions. We aimed at optimizing EV isolation from plasma and describing the differential lipid content of EV, as compared to whole plasma. As pilot study, we evaluated the diagnostic potential of lipidomic signature of circulating EV in patients with a diagnosis of ST-segment-elevation myocardial infarction (STEMI). STEMI patients were evaluated before reperfusion and 24-h after primary percutaneous coronary intervention. Twenty sphingolipid species were quantified by liquid-chromatography tandem-mass-spectrometry. EV-ceramides, -dihydroceramides, and -sphingomyelins increased in STEMI vs. matched controls and decreased after reperfusion. Their levels correlated to hs-troponin, leucocyte count, and ejection fraction. Plasma sphingolipids levels were 500-to-700-fold higher as compared to EV content; nevertheless, only sphingomyelins differed in STEMI vs. control patients. Different sphingolipid species were enriched in EV and their linear combination by machine learning algorithms accurately classified STEMI patients at pre-PCI evaluation. In conclusion, EV lipid signature discriminates STEMI patients. These findings may contribute to the identification of novel biomarkers and signaling mechanisms related to cardiac ischemia.

Abstract
Phospholamban (PLN) p.Arg14del cardiomyopathy is characterized by a distinct arrhythmogenic biventricular phenotype that can be predominantly left ventricular, right ventricular, or both. Our aim was to further elucidate distinct features of this cardiomyopathy with respect to the distribution of desmosomal proteins observed by immunofluorescence (IF) in comparison to desmosomal arrhythmogenic cardiomyopathy and co-existent genetic variants. We studied eight explanted heart specimens from PLN p.Arg14del mutation carriers. Macro- and microscopic examination revealed biventricular presence of fibrofatty replacement and interstitial fibrosis. Five out of 8 (63%) patients met consensus criteria for both arrhythmogenic right ventricular cardiomyopathy (ARVC) and dilated cardiomyopathy (DCM). In four cases, targeted next-generation sequencing revealed one additional pathogenic variant and six variants of unknown significance. IF showed diminished junction plakoglobin signal intensity at the intercalated disks in 4 (67%) out of 6 cases fulfilling ARVC criteria but normal intensity in both cases fulfilling only DCM criteria. Notably, the four cases with diminished junction plakoglobin were also those where an additional gene variant was detected. IF for two proteins recently investigated in desmosomal arrhythmogenic cardiomyopathy (ACM), synapse-associated protein 97 and glycogen synthase kinase-3 beta, showed a distinct distributional pattern in comparison to desmosomal ACM. In 7 (88%) out of 8 cases we observed both a strong synapse-associated protein 97 signal at the sarcomeres and no glycogen synthase kinase-3 beta translocation to the intercalated discs. Phospholamban p.Arg14del cardiomyopathy is characterized by a distinct molecular signature compared to desmosomal ACM, specifically a different desmosomal protein distribution. This study substantiates the idea that additional genetic variants play a role in the phenotypical heterogeneity.

Abstract
Arrhythmogenic cardiomyopathy (AC) is a heart muscle disease clinically characterized by life-threatening ventricular arrhythmias and pathologically by an acquired and progressive dystrophy of the ventricular myocardium with fibro-fatty replacement. Due to an estimated prevalence of 1:2000-1:5000, AC is listed among rare diseases. A familial background consistent with an autosomal-dominant trait of inheritance is present in most of AC patients; recessive variants have also been reported, either or not associated with palmoplantar keratoderma and woolly hair. AC-causing genes mostly encode major components of the cardiac desmosome and up to 50 % of AC probands harbor mutations in one of them. Mutations in non-desmosomal genes have been also described in a minority of AC patients, predisposing to the same or an overlapping disease phenotype. Compound/digenic heterozygosity was identified in up to 25 % of AC-causing desmosomal gene mutation carriers, in part explaining the phenotypic variability. Abnormal trafficking of intercellular proteins to the intercalated discs of cardiomyocytes and Wnt/beta catenin and Hippo signaling pathways have been implicated in disease pathogenesis. AC is a major cause of sudden death in the young and in athletes. The clinical picture may include a sub-clinical phase; an overt electrical disorder; and right ventricular or biventricular pump failure. Ventricular fibrillation can occur at any stage. Genotype-phenotype correlation studies led to identify biventricular and dominant left ventricular variants, thus supporting the use of the broader term AC. Since there is no “gold standard” to reach the diagnosis of AC, multiple categories of diagnostic information have been combined and the criteria recently updated, to improve diagnostic sensitivity while maintaining specificity. Among diagnostic tools, contrast enhanced cardiac magnetic resonance is playing a major role in detecting left dominant forms of AC, even preceding morpho-functional abnormalities. The main differential diagnoses are idiopathic right ventricular outflow tract tachycardia, myocarditis, sarcoidosis, dilated cardiomyopathy, right ventricular infarction, congenital heart diseases with right ventricular overload and athlete heart. A positive genetic test in the affected AC proband allows early identification of asymptomatic carriers by cascade genetic screening of family members. Risk stratification remains a major clinical challenge and antiarrhythmic drugs, catheter ablation and implantable cardioverter defibrillator are the currently available therapeutic tools. Sport disqualification is life-saving, since effort is a major trigger not only of electrical instability but also of disease onset and progression. We review the current knowledge of this rare cardiomyopathy, suggesting a flowchart for primary care clinicians and geneticists.

Abstract
Dominant mutations in desmocollin-2 (DSC2) gene cause arrhythmogenic cardiomyopathy (ACM), a progressive heart muscle disease characterized by ventricular tachyarrhythmias, heart failure, and risk of juvenile sudden death. Recessive mutations are rare and are associated with a cardiac or cardiocutaneous phenotype. Here, we evaluated the impact of a homozygous founder DSC2 mutation on clinical expression of ACM. An exon-by-exon analysis of the DSC2 coding region was performed in 94 ACM index patients. The c.536A>G (p.D179G) mutation was identified in 5 patients (5.3%), 4 of which resulted to be homozygous carriers. The 5 subjects shared a conserved haplotype, strongly indicating a common founder. Genetic and clinical investigation of probands' families revealed that p.D179G homozygous carriers displayed severe forms of biventricular cardiomyopathy without hair or skin abnormalities. The only heterozygous proband, who carried an additional variant of unknown significance in αT-catenin gene, showed a mild form of ACM without left ventricular involvement. All heterozygous family members were clinically asymptomatic. In conclusion, this is the first homozygous founder mutation in DSC2 gene identified among Italian ACM probands. Our findings provide further evidence of the occurrence of recessive DSC2 mutations in patients with ACM predominantly presenting with biventricular forms of the disease.

Abstract
AIMS Dysregulation of the transforming growth factor beta (TGF-β) 1 pathway has been associated with either syndromic or isolated mitral valve (MV) prolapse due to myxoid degeneration (floppy MV). The activation of Smad receptor-mediated intracellular TGF-β pathway and its effect on adherens junction (AJ) molecular pattern of activated valvular interstitial cells (VICs) in MV prolapse are herein investigated. METHODS Floppy MV leaflets were obtained from 30 patients (24 males, mean age 55.5±12.7 years) who underwent surgical repair, and 10 age- and sex-matched Homograft Tissue Bank samples served as controls. MV leaflet cellular and extracellular matrix composition, including collagen I and III, was evaluated by histology and transmission electron microscopy. Smad2 active phosphorylated form (p-Smad2), α-smooth muscle actin (α-SMA), and junctional proteins (N-cadherin, cadherin-11, β-catenin, plakoglobin, plakophilin-2) in VICs were assessed by immunohistochemistry and immunofluorescence and confirmed by immunoblotting. Quantitative real-time polymerase chain reaction was carried out for components of TGF-β pathway cascade and filamin A (FLN-A). RESULTS Floppy MV leaflets were thicker (P<.001) and had higher α-SMA+ cell density (P=.002) and collagen III expression (P<.001) than controls. Enhanced p-Smad2 nuclear immunoreactivity (P<.001) and TGF-β1 gene (P=.045), TIMP1 (P=.020), and CTGF (P=.047) expression but no differences in FLN-A and total Smad2 gene expression levels were found between floppy MV and controls. Higher expression of cadherin-11, either exclusively or in colocalization with N-cadherin, and aberrant presence of plakophilin-2 at the AJ were found in floppy MV vs. CONCLUSIONS TGF-β1 pathway activation in nonsyndromic MV prolapse induces VICs differentiation into contractile myofibroblasts and is associated with changes in the molecular pattern of the AJ, with increased cadherin-11 and aberrant plakophilin-2 expression. AJ reinforcement might promote latent TGF-β1 activation leading to extracellular matrix remodeling in floppy MV.

Abstract
Arrhythmogenic cardiomyopathy (ACM) is an inherited cardiac disease characterized by myocardial atrophy, fibro-fatty replacement, and a high risk of ventricular arrhythmias that lead to sudden death. In 2009, genetic data from 57 publications were collected in the arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) Genetic Variants Database (freeware available at http://www.arvcdatabase.info), which comprised 481 variants in eight ACM-associated genes. In recent years, deep genetic sequencing has increased our knowledge of the genetics of ACM, revealing a large spectrum of nucleotide variations for which pathogenicity needs to be assessed. As of April 20, 2014, we have updated the ARVD/C database into the ARVD/C database to contain more than 1,400 variants in 12 ACM-related genes (PKP2, DSP, DSC2, DSG2, JUP, TGFB3, TMEM43, LMNA, DES, TTN, PLN, CTNNA3) as reported in more than 160 references. Of these, only 411 nucleotide variants have been reported as pathogenic, whereas the significance of the other approximately 1,000 variants is still unknown. This comprehensive collection of ACM genetic data represents a valuable source of information on the spectrum of ACM-associated genes and aims to facilitate the interpretation of genetic data and genetic counseling.

Abstract
Mitochondrial dysfunction and oxidative stress are considered central in dopaminergic neurodegeneration in Parkinson’s disease (PD). Oxidative stress occurs when the endogenous antioxidant systems are overcome by the generation of reactive oxygen species (ROS). A plausible source of oxidative stress, which could account for the selective degeneration of dopaminergic neurons, is the redox chemistry of dopamine (DA) and leads to the formation of ROS and reactive dopamine-quinones (DAQs). Superoxide dismutase 2 (SOD2) is a mitochondrial enzyme that converts superoxide radicals to molecular oxygen and hydrogen peroxide, providing a first line of defense against ROS. We investigated the possible interplay between DA and SOD2 in the pathogenesis of PD using enzymatic essays, site-specific mutagenesis, and optical and high-field-cw-EPR spectroscopies. Using radioactive DA, we demonstrated that SOD2 is a target of DAQs. Exposure to micromolar DAQ concentrations induces a loss of up to 50% of SOD2 enzymatic activity in a dose-dependent manner, which is correlated to the concomitant formation of protein aggregates, while the coordination geometry of the active site appears unaffected by DAQ modifications. Our findings support a model in which DAQ-mediated SOD2 inactivation increases mitochondrial ROS production, suggesting a link between oxidative stress and mitochondrial dysfunction.

Abstract
BACKGROUND Breast reconstruction after a mastectomy, today is considered the best choice to improve the quality of life for the patient. The aim of the procedure is to consider the aesthetic results obtained and the various involvements, comparing them with those already reported in literature. METHODS. There is no certain data of the number of breast reconstructions performed in Italy in the few years. In 1999, in Veneto, reconstruction surgery after total breast removal, represented only 16% of the operations. In our surgery Division, from 1996 to 2000, there were breast reconstructions performed, either immediately or delayed on 87 patients out of 118 after mastectomy. 73.7% none over the age of 60 (range 27-60). The breast removal technique used is the Madden, while, for the reconstruction we have put into effect the submuscle prosthetic implant; 63 patients were subject to follow-up treatment during the period of 10 to 36 months. RESULTS Seventy-eight percent of the women have judged the final aesthetic results the same or better than expected. Based on reconstruction with prosthesis, is the preferred procedure, even with serious complications which do not always influence the final results. This preference is because of the reduced operation time and the psychological and physical benefits due to immediate restoral of the mammary volume and shape. CONCLUSIONS Some problems (Garavaglia Law) have slowed down the diffusion in Italy of this type of treatment which is now receiving more and more request and approval by the women affected with breast cancer.

Abstract
The aim of this work was to ascertain whether free radicals play a causal role in the injury occurring in myocardial ischemia and reperfusion. To this purpose we observed whether spin-trapping compounds protect the heart when used at a concentration capable of reacting with free radicals. The lipophilic spin trap alpha-phenyl-t-butyl nitrone (PBN) was used because it is taken up by the myocites. Isolated Langendorff rat hearts were subjected to ischemia according to two schemes: "Model A" = 30 min zero-flow ischemia followed by 30 min reperfusion; "Model B" = 60 min of low-flow ischemia (10% of the individual value; N2 saturated) followed by 30 min reperfusion. Treated groups received in addition 5.0 mM PBN which was supplied continuously. The following parameters were measured throughout the experiment: contractile performance (RPP); coronary flow (CF); CPK; phosphocreatine (PCr), ATP, inorganic phosphate (Pi), intracellular pH (pHi). The pathology obtained by "Model A" is more severe than that of Model B, and partly irreversible. During the ischemic phase in "Model A", contractility, PCr and ATP dropped to near zero; during initial reflow CPK rose about 13-fold and Pi rose 2.5-fold, while pHi decreased to 6.1. During reperfusion, a partial recovery of PCr, Pi and pHi was observed, while RPP and ATP did not increase; PBN treatment improved significantly PCr and CPK, while the other parameters were unaffected. During ischemia, "Model B" hearts showed a drop of contractility to near zero, of PCr to 35%, of ATP to 50%; CPK rose 7-fold and Pi 1.5-fold; pHi was not modified. During reperfusion, all parameters recovered in part, with exception of Pi. PBN developed a marked protective activity on all tested parameters, which gained a nearly normal value. The results of the present investigations show that the lipophilic spin trap PBN partly protects the heart from the ischemia/reperfusion injury, thus confirming that free radicals play a causal role in this pathology; the continuous loading of the tissue with the drug can be an important factor for obtaining the protective effect.

Abstract
Summary
The possibility of different behaviours of 60Co and 60mCo in the Szilard-Chalmers recoil was investigated and proved in [Co(NH)3)6] (NO3)3 and trans
- [Co en2(NO2)2] NO3. It was found that the retentions of 60Co and 60mCo atoms in the original compounds, for irradiation time approaching zero, are different. Particularly the ratio of i0B,Co to eoCo retentions at zero irradiation time is 0.90 + 0.02 for [Co(NH3)5] . (NO3)3 and 1.26 + 0.04 for trans
- [Co en2(NO2)] NO3. The annealing kinetics of recoiled 60Co and 60mCo atoms under fast neutron and γ-ray irradiations at a temperature of 40 °C are also different.
