Abstract
VDAC3 is the least known isoform of the mammalian voltage-dependent anion selective channels of the outer mitochondrial membrane. It has been recently shown that cysteine residues of VDAC3 are found over-oxidized. The VDAC3 cysteine over-oxidation was associated with the oxidizing environment and the abundance of reactive oxygen species (ROS) in the intermembrane space. In this work, we have examined the role of VDAC3 in general pathogenic mechanisms at the basis of mitochondrial dysfunction and involving the mitochondrial quality control. Many of the diseases reported here, including cancer and viral infections, are often associated with significant changes in the intracellular redox state. In this sense, VDAC3 bearing oxidative modifications could become marker of the oxidative load in the mitochondria and part of the ROS signaling pathway.

Abstract
Voltage-Dependent Anion selective Channels (VDAC) are pore-forming mitochondrial outer membrane proteins. In mammals VDAC3, the least characterized isoform, presents a set of cysteines predicted to be exposed toward the intermembrane space. We find that cysteines in VDAC3 can stay in different oxidation states. This was preliminary observed when, in our experimental conditions, completely lacking any reducing agent, VDAC3 presented a pattern of slightly different electrophoretic mobilities. This observation holds true both for rat liver mitochondrial VDAC3 and for recombinant and refolded human VDAC3. Mass spectroscopy revealed that cysteines 2 and 8 can form a disulfide bridge in native VDAC3. Single or combined site-directed mutagenesis of cysteines 2, 8 and 122 showed that the protein mobility in SDS-PAGE is influenced by the presence of cysteine and by the redox status. In addition, cysteines 2, 8 and 122 are involved in the stability control of the pore as shown by electrophysiology, complementation assays and chemico-physical characterization. Furthermore, a positive correlation between the pore conductance of the mutants and their ability to complement the growth of porin-less yeast mutant cells was found. Our work provides evidence for a complex oxidation pattern of a mitochondrial protein not directly involved in electron transport. The most likely biological meaning of this behavior is to buffer the ROS load and keep track of the redox level in the inter-membrane space, eventually signaling it through conformational changes.

Abstract
Ultrahigh energy cosmic ray air showers probe particle physics at energies beyond the reach of accelerators. Here we introduce a new method to test hadronic interaction models without relying on the absolute energy calibration, and apply it to events with primary energy 6-16 EeV (E_{CM}=110-170 TeV), whose longitudinal development and lateral distribution were simultaneously measured by the Pierre Auger Observatory. The average hadronic shower is 1.33±0.16 (1.61±0.21) times larger than predicted using the leading LHC-tuned models EPOS-LHC (QGSJetII-04), with a corresponding excess of muons.

Abstract
Superoxide Dismutase 1 mutants associate with 20–25% of familial Amyotrophic Lateral Sclerosis (ALS) cases, producing toxic aggregates on mitochondria, notably in spinal cord. The Voltage Dependent Anion Channel isoform 1 (VDAC1) in the outer mitochondrial membrane is a docking site for SOD1 G93A mutant in ALS mice and the physiological receptor of Hexokinase I (HK1), which is poorly expressed in mouse spinal cord. Our results demonstrate that HK1 competes with SOD1 G93A for binding VDAC1, suggesting that in ALS spinal cord the available HK1-binding sites could be used by SOD1 mutants for docking mitochondria, producing thus organelle dysfunction. We tested this model by studying the action of a HK1-N-terminal based peptide (NHK1). This NHK1 peptide specifically interacts with VDAC1, inhibits the SOD1 G93A binding to mitochondria and restores the viability of ALS model NSC34 cells. Altogether, our results suggest that NHK1 peptide could be developed as a therapeutic tool in ALS, predicting an effective role also in other proteinopathies.

Abstract
We measure the energy emitted by extensive air showers in the form of radio emission in the frequency range from 30 to 80 MHz. Exploiting the accurate energy scale of the Pierre Auger Observatory, we obtain a radiation energy of 15.8±0.7(stat)±6.7(syst) MeV for cosmic rays with an energy of 1 EeV arriving perpendicularly to a geomagnetic field of 0.24 G, scaling quadratically with the cosmic-ray energy. A comparison with predictions from state-of-the-art first-principles calculations shows agreement with our measurement. The radiation energy provides direct access to the calorimetric energy in the electromagnetic cascade of extensive air showers. Comparison with our result thus allows the direct calibration of any cosmic-ray radio detector against the well-established energy scale of the Pierre Auger Observatory.

Abstract
Cu/Zn Superoxide Dismutase (SOD1), the most important antioxidant defense against ROS in eukaryotic cells, localizes in cytosol and intermembrane space of mitochondria (IMS). Several evidences show a SOD1 intersection with both fermentative and respiratory metabolism. The Voltage Dependent Anion Channel (VDAC) is the main pore-forming protein in the mitochondrial outer membrane (MOM), and is considered the gatekeeper of mitochondrial metabolism. Saccharomyces cerevisiae lacking VDAC1 (Δpor1) is a very convenient model system, since it shows an impaired growth rate on non-fermentable carbon source. Transformation of Δpor1 yeast with human SOD1 completely restores the cell growth deficit in non-fermentative conditions and re-establishes the physiological levels of ROS, as well as the mitochondrial membrane potential. No similar result was found upon yeast SOD1 overexpression. A previous report highlighted the action of SOD1 as a transcription factor. Quantitative Real-Time PCR showed that β-barrel outer-membrane encoding-genes por2, tom40, sam50 are induced by hSOD1, but the same effect was not obtained in Δpor1Δpor2 yeast, indicating a crucial function for yVDAC2. Since the lack of VDAC1 in yeast can be considered a stress factor for the cell, hSOD1 could relieve it stimulating the expression of genes bringing to the recovery of the MOM function. Our results suggest a direct influence of SOD1 on VDAC.

Abstract
There is merit in considering a simple toxicological screening method that evaluates the total cytotoxic potential of e-liquids or electronic cigarettes (ECs) aerosol emissions in one single testing. However, there is growing confusion, with several researchers endorsing their personal solution to the problem. Here, we discuss as an example the recent paper by Scheffler and colleagues, in which the authors suggest that more relevant and well differentiated cell lines from human airways could be the most suitable candidates for toxicological evaluation of ECs aerosol emissions. We advance recommendations for validated protocols and advocate for an international coordinated effort aimed at establishing consensus on methodology.

Abstract
Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with [Formula: see text] eV by analyzing cosmic rays with energies above [Formula: see text] eV arriving within an angular separation of approximately 15[Formula: see text]. We characterize the energy distributions inside these regions by two independent methods, one searching for angular dependence of energy-energy correlations and one searching for collimation of energy along the local system of principal axes of the energy distribution. No significant patterns are found with this analysis. The comparison of these measurements with astrophysical scenarios can therefore be used to obtain constraints on related model parameters such as strength of cosmic-ray deflection and density of point sources.

Abstract
Amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD-TDP) are two neurodegenerative disorders characterized by the accumulation of TDP-43. TDP-43 is proteolitically cleaved to generate two major C-terminal fragments of 35 and 25 kDa. The latter, known as TDP-25, is a consistent feature of FTLD-TDP and ALS; however, little is known about its role in disease pathogenesis. We have previously developed transgenic mice overexpressing low levels of TDP-25 (TgTDP-25(+/0)), which at 6 months of age show mild cognitive impairments and no motor deficits. To better understand the role of TDP-25 in the pathogenesis of ALS and FTLD-TDP, we generated TDP-25 homozygous mice (TgTDP-25(+/+)), thereby further increasing TDP-25 expression. We found a gene-dosage effect on cognitive and motor function at 15 months of age, as the TgTDP-25(+/+) showed more severe spatial and working memory deficits as well as worse motor performance than TgTDP-25(+/0) mice. These behavioral deficits were associated with increased soluble levels of TDP-25 in the nucleus and cytosol. Notably, high TDP-25 levels were also linked to reduced autophagy induction and proteasome function, two events that have been associated with both ALS and FTLD-TDP. In summary, we present strong in vivo evidence that high levels of TDP-25 are sufficient to cause behavioral deficits and reduce function of two of the major protein turnover systems: autophagy and proteasome. These mice represent a new tool to study the role of TDP-25 in the pathogenesis of ALS and FTLD-TDP.

Abstract
In higher eukaryotes three different VDAC genes encode three homologous proteins which do not show the same activity. VDAC1 and VDAC2 isoforms have been characterized while VDAC3 isoform is still elusive. To explore VDAC3 protein interactions, we have established a stable cell line expressing a fluorescent and dual-tagged construct. This clone expresses a stable amount of VDAC3. Live cell imaging shows that fluorescent VDAC3 localizes in the mitochondria. Proteins interacting with VDAC3 have been separated by tandem-affinity purification and 2-D gel electrophoresis and identified by mass spectrometry. In the list of putative interacting proteins, there are cytosolic, mitochondrial, cytoskeletal and ER proteins. Coherent pathways like cell redox homeostasis, response to stress, formation/rearrangement of disulfide bonds, response to unfolded proteins or protein folding have been found to be related to clusters of proteins identified in this experiment. The list of associated proteins has been validated by immunoprecipitation experiments utilizing specific antibodies. Likely biological and pathological processes have been analyzed. Cytosolic proteins associated with VDAC3 include tubulins and cytoskeletal proteins, stress sensors, chaperones and proteasome components, redox-mediating enzymes such as protein disulphide isomerase. The overall picture points to a role for VDAC3 as mediator for the organization of protein complexes and regulator of the traffic of misfolded or non-folded proteins evoked from different stimuli.

Abstract
Voltage-Dependent Anion selective Channel maintains the permeability of the outer mitochondrial membrane and is relevant in bioenergetic metabolism and apoptosis. The structure of the protein was shown to be a β-barrel formed by 19 strands. The topology or sideness of the pore has been predicted with various approaches but a general consensus was never reached. This is an important issue since VDAC is considered receptor of Hexokinase and Bcl-2. We fused at VDAC1 C-terminus two tags separated by a caspase cleavage site. Activation in cellulo of caspases was used to eventually separate the two reporters. This experiment did not require the isolation of mitochondria and limited the possibility of outer membrane rupture due to similar procedures. Our results show that the C-terminus end of VDAC faces the mitochondrial inter-membrane space.

Abstract
We report a measurement of the proton-air cross section for particle production at the center-of-mass energy per nucleon of 57 TeV. This is derived from the distribution of the depths of shower maxima observed with the Pierre Auger Observatory: systematic uncertainties are studied in detail. Analyzing the tail of the distribution of the shower maxima, a proton-air cross section of [505±22(stat)(-36)(+28)(syst)] mb is found.

Abstract
BACKGROUND Cigarette smoking is associated with cardiovascular morbidity and mortality. Exposure to cigarette smoke can cause endothelial dysfunction with impaired endothelium-dependent vasodilation and 'endothelial activation', which predispose to atherothrombosis. The effects of continued smoking and smoking cessation on the level of endothelial, platelet and clotting activation have not been described previously. Here, we prospectively monitored changes in circulating endothelial-coagulative activation markers in smokers undertaking smoking cessation. METHOD This 12-month prospective study of 174 smokers with no commonly acquired atherothrombotic risk factors underwent an intensive smoking-cessation programme investigating the effect of quitting on circulating levels of von Willebrand's Factor Antigen (vWF:Ag), soluble Thrombomodulin (sTM), d-Dimer (d-D), prothrombin fragment F1+2 (F1+2), platelet factor-4 (PF4) and β-Thromboglobulin (β-TG). Blood samples and study measures were collected and compared at baseline and at 2, 6 and 12months after smoking cessation from quitters and relapsers'. RESULTS No significant differences in demographic or laboratory parameters at baseline were observed between the study groups. Significant changes in von Willebrand's Factor activity were observed at 2months after smoking cessation, with levels decreasing from 141·8% to 113·6%. Substantial modifications in d-Dimer, prothrombin fragment F1 +2, platelet factor-4 and β-thromboglobulin concentrations were observed only at 6 and 12months after smoking cessation. Positive associations between baseline levels of these biomarkers and number of pack per years have been demonstrated. CONCLUSIONS Chronic exposure to cigarette smoke sustains the activation of the endothelial-coagulative system and abstinence may result in the improvement of several endothelial-coagulative abnormalities in regular smokers. This may translate into an overall decline in cardiovascular risk.

Abstract
General diffusion porins are passive transmembrane channels. We have explored the possibility to create artificial nanopores starting from natural β-barrel structures. Structural elements of bacterial porins were used to build a series of artificial nanopores. The basic module was selected by multi-alignment of general diffusion porins. The sequence corresponded to a highly conserved motif containing two β-strands, which was obtained from Escherichia coli OmpF. Dimeric to octameric repeats were obtained through cDNA recombinant technology. The hexameric repeat was used to test its properties. This protein was expressed, purified and reconstituted in the planar bilayer membranes. It was able to form channels in membranes with a conductance of 300 pS in 150 mm KCl and did not show any relevant voltage-dependence.

Abstract
Endothelial activation/injury following exposure to cigarette smoke may explain incidence of atherosclerosis and cardiovascular disease in smokers. We investigated cigarette smoke extract (CSE) effects relative to activation, injury, and survival of human umbilical vein endothelial cells (HUVEC) and compared circulating levels of specific endothelial activation markers between smokers and healthy non-smokers before and after smoking cessation. Viability and toxicity of HUVEC were tested by MTT and LDH assay. Release (by endothelial cells) and circulating levels (in smokers) of von Willebrand Factor (vWF), thrombomodulin (TM), was evaluated by ELISA. Incubation with increasing concentrations of CSE reduced the percentage of viable cells, being 33.9%, 23.9% after CSE 4%, 6% respectively. Dose- and time-dependent release of LDH was observed after incubation with CSE. vWF, TM release were assayed after CSE 2% HUVEC stimulation. Significant 42%, 61%, 76% increase in vWF concentration was detected respectively at 30', 60', 120'. Reduction in circulating levels of vWF, from a median value of 144.0% to 123.7%, was observed in the quitters group after smoking cessation. Exposure to cigarette smoke is cytotoxic and induces activation/injury of endothelium in vitro and in vivo. These findings may provide pathogenetic basis by which smoking can predispose to development of atherothrombosis and cardiovascular disease.
