Abstract
Helicobacter pylori (HP) is among the most common pathogens causing infection in humans worldwide. Oxidative stress and gastric inflammation are involved in the progression of HP-related gastric diseases, and they can be targeted by integrating conventional antibiotic treatment with polyphenol-enriched natural products. In this work, we characterised three different propolis extracts and evaluated their stability under in vitro simulated gastric digestion, compared to their main constituents alone. The extract with the highest stability to digestion (namely, the dark propolis extract, DPE) showed a minimum bactericidal concentration (MBC) lower than 1 mg/mL on HP strains with different virulence factors. Finally, since urease is one of the virulence factors contributing to the establishment of a microenvironment that promotes HP infection, we evaluated the possible inhibition of this enzyme by using molecular docking simulations and in vitro colorimetric assay, showing that galangin and pinocembrin may be involved in this activity.

Abstract
In this work we review the latest strategies for the bottom-up assembly of energetically autonomous artificial cells capable of transducing light energy into chemical energy and support internalized metabolic pathways. Such entities are built by taking inspiration from the photosynthetic machineries found in nature which are purified and reconstituted directly in the membrane of artificial compartments or encapsulated in form of organelle-like structures. Specifically, we report and discuss recent examples based on liposome-technology and multi-compartment (nested) architectures pointing out the importance of this matter for the artificial cell synthesis research field and some limitations and perspectives of the bottom-up approach.

Abstract
The use of surfactants represents a viable strategy to boost the removal yield of Dense Non-Aqueous Phase Liquids (DNAPLs) from groundwater and to shorten the operational timing of the remediation process. Surfactants, in general, help in reducing the interfacial tension at the DNAPL/water interface and enhance the solubility of the pollutant in the water phase through the formation of dispersed systems, such as micelles and emulsions. In this paper, we show that a suitable choice of a surfactant, in this case belonging to the bio-degradable class of ethoxylated alcohols, allows for the formation of hydrodynamic interfacial instabilities that further enhances the dissolution rate of the organic pollutant into the water phase. In a stratified configuration (denser organic phase at the bottom and lighter water phase on top), the instabilities appear as upward-pointing fingers that originate from the inversion of the local density at the interface. This inversion stems from the synergetic coupling of two effects promoted by the ethoxylated surfactant: i) the enhanced co-solubility of the DNAPL into the water (and viceversa), and (ii) the differential diffusion of the DNAPL and the surfactant in the aqueous phase. By dissolving into the DNAPL, the surfactant also reduces locally the surface tension at the liquid-liquid interface, thereby inducing transversal Marangoni flows. In our work, we carefully evaluated the effects of the concentration of different surfactants (two different ethoxylated alcohols, sodium dodecylsulphate, cetyltrimethyl ammonium bromide, N-tetradecyl-N, N-dimethylamine oxide and bis(2-ethylhexyl) sulfosuccinate sodium salt) on the onset of the instabilities in 3 different DNAPLs/water stratifications, namely chloroform, trichloroethylene and tetrachloroethylene, with a special emphasis on the trichloroethylene/water system. By means of a theoretical model and nonlinear simulations, supported by surface tension, density and diffusivity measurements, we could provide a solid explanation to the observed phenomena and we found that the type of the dispersed system, the solubility of the DNAPL into the water phase, the solubility of the surfactant in the organic phase, as well as the relative diffusion and density of the surfactant and the DNAPL in the aqueous phase, are all key parameters for the onset of the instabilities. These results can be exploited in the most common remediation techniques.

Abstract
Proteomics has exposed a plethora of posttranslational modifications, but demonstrating functional relevance requires new approaches. Top-down proteomics of intact proteins has the potential to fully characterize protein modifications in terms of amount, site(s), and the order in which they are deposited on the protein; information that so far has been elusive to extract by shotgun proteomics. Data acquisition and analysis of intact multimodified proteins have however been a major challenge, in particular for positional isomers that carry the same number of modifications at different sites. Solutions were previously proposed to extract this information from fragmentation spectra, but these have so far mainly been limited to peptides and have entailed a large degree of manual interpretation. Here, we apply high-resolution Orbitrap fusion top-down analyses in combination with bioinformatics approaches to attempt to characterize multiple modified proteins and quantify positional isomers. Automated covalent fragment ion type definition, detection of mass precision and accuracy, and extensive use of replicate spectra increase sequence coverage and drive down false fragment assignments from 10% to 1.5%. Such improved performance in fragment assignment is key to localize and quantify modifications from fragment spectra. The method is tested by investigating positional isomers of Ubiquitin mixed in known concentrations, which results in quantification of high ratios at very low standard errors of the mean (<5%), as well as with synthetic phosphorylated peptides. Application to multiphosphorylated Bora provides an estimation of the so far unknown stoichiometry of the known set of phosphosites and uncovers new sites from hyperphosphorylated Bora. ETD fragmentation reveals the presence of positional isomers. For proteins up to 40 kDa these positional isomers can accurately be quantified. For in-vitro phosphorylated BoraNT a wide array of positional isomers is revealed. Use of Fragment ion FDR levels improve the quality of extracted stoichiometries.

Abstract
A mm thick free-standing gel containing lipid vesicles made of 2-oleoyl-1-palmitoyl-sn-glycero-3-phosphocholine (POPC) was studied by scanning Small Angle X-ray Scattering (SAXS) and X-ray Transmission (XT) microscopies. Raster scanning relatively large volumes, besides reducing the risk of radiation damage, allows signal integration, improving the signal-to-noise ratio (SNR), as well as high statistical significance of the dataset. The persistence of lipid vesicles in gel was demonstrated, while mapping their spatial distribution and concentration gradients. Information about lipid aggregation and packing, as well as about gel density gradients, was obtained. A posteriori confirmation of lipid presence in well-defined sample areas was obtained by studying the dried sample, featuring clear Bragg peaks from stacked bilayers. The comparison between wet and dry samples allowed it to be proved that lipids do not significantly migrate within the gel even upon drying, whereas bilayer curvature is lost by removing water, resulting in lipids packed in ordered lamellae. Suitable algorithms were successfully employed for enhancing transmission microscopy sensitivity to low absorbing objects, and allowing full SAXS intensity normalization as a general approach. In particular, data reduction includes normalization of the SAXS intensity against the local sample thickness derived from absorption contrast maps. The proposed study was demonstrated by a room-sized instrumentation, although equipped with a high brilliance X-ray micro-source, and is expected to be applicable to a wide variety of organic, inorganic, and multicomponent systems, including biomaterials. The employed routines for data reduction and microscopy, including Gaussian filter for contrast enhancement of low absorbing objects and a region growing segmentation algorithm to exclude no-sample regions, have been implemented and made freely available through the updated in-house developed software SUNBIM.

Abstract
Cross-linking mass spectrometry (XL-MS) is an efficient technique for uncovering structural features and interactions of the in-solution state of the proteins under investigation. Distance constraints obtained by this technique are highly complementary to classical structural biology approaches like X-ray crystallography and cryo-EM and have successfully been leveraged to shed light on protein structures of increasing size and complexity. To accomplish this, small reagents are used that typically incorporate two amine reactive moieties connected by a spacer arm and that can be applied in solution to protein structures of any size. Over the years, many reagents initially developed for different applications were adopted, and others were specifically developed for XL-MS. This has resulted in a vast array of options, making it difficult to make the right choice for specific experiments. Here, we delve into the previous decade of published XL-MS literature to uncover which workflows have been predominantly applied. We focus on application papers as these represent proof that biologically valid results can be extracted. This ignores some more recent approaches that did not have sufficient time to become more widely applied, for which we supply a separate discussion. From our selection, we extract information on the types of samples, cross-linking reagent, prefractionation, instruments, and data analysis, to highlight widely used workflows. All of the results are summarized in an easy-to-use flow chart defined by selection points resulting from our analysis. Although potentially biased by our own experiences, we expect this overview to be useful for novices stepping into this rapidly expanding field.

Abstract
BACKGROUND Some clinical conditions, including dementia, compromise cognitive functions involved in decision-making processes, with repercussions on the ability to subscribe a will. Because of the increasing number of aged people with cognitive impairment there is an acute and growing need for decision-making capacity evidence-based assessment. AIMS Our study investigates the relationship between writing abilities and cognitive integrity to see if it is possible to make inferences on decision-making capacity through handwriting analysis. We also investigated the relationship between signature ability and cognitive integrity. METHODS Thirty-six participants with diagnosis of MCI and 38 participants with diagnosis of initial dementia were recruited. For each subject we collected two samples of signature-an actual and a previous one-and an extract of spontaneous writing. Furthermore, we administered a neuropsychological battery to investigate cognitive functions involved in decision-making. RESULTS We found significant correlations between spontaneous writing indexes and neuropsychological test results. Nonetheless, the index of signature deterioration does not correlate with the level of cognitive decline. DISCUSSION Our results suggest that a careful analysis of spontaneous writing can be useful to make inferences on decision-making capacity, whereas great caution should be taken in attributing validity to handwritten signature of subjects with MCI or dementia. CONCLUSIONS The analysis of spontaneous writing can be a reliable aid in cases of retrospective evaluation of cognitive integrity. On the other side, the ability to sign is not an index of cognitive integrity.

Abstract
Critical limb ischaemia often leads to amputation of the limb and potential mortality. Moreover, there are still significant problems with current therapeutic treatments, according to poor revascularisation of degenerated tissue probably due to modifications within the microenvironment. This study is focused on the changes of structure and bioactivity of glycosaminoglycans (GAGs), especially heparan sulphate (HS) and chondroitin sulphate (CS) in rat Extensor Digitorum Longus (EDL) muscle after ischaemia. Male Wistar rats were subjected to ischaemic-injury by ligation of the neurovascular trunk accompanying EDL-tendon. After 4, 8, 15, 21, 60 and 90 d, the rats were sacrificed and the muscles were collected and submitted to histological, biochemical and gene expression assays. We demonstrated that ischaemia induced modification of expression of enzymes involved in GAG biosynthesis which correlated with significant changes in HS and CS structural features such as size and sulphation pattern. These major structural changes are associated to modifications of GAG abilities to bind growth factors and to modulate cell activity. Moreover, a CS hallmark of injury is maintained as well after the regeneration process. Finally, we showed the relevance of the role of this glycanic matrix remodelling, since a GAG mimetic treatment accelerated muscle repair after ischaemia.

Abstract
INTRODUCTION There is no classification for acquired forearm deformities. A clinical-radiographic study was conducted to classify these deformities and evaluate the results. MATERIALS AND METHODS Thirteen patients with forearm deformities following traumas or their treatment were included (11 men and two women, from 2000 to 2010). Mean age was 31 years (range 10-75 years). Initial treatment was conservative in five patients and surgical in eight patients. One segment was affected in seven patients (the radius in four patients, the ulna in three), and both segments were affected in six patients. Location assessment: 2 projections X-rays, including wrist and elbow. Deformity location: proximal, diaphisary, distal, defined with the abbreviation, in distal sense, R1, R2, R3 for the radius, and U1, U2, U3 for the ulna. Primary and secondary deformities were distinguished: secondary deformities occurred later in a different location than the primary one. Six patients were treated with plate and screws. An external fixator was used in six patients. One patient was treated with bone resection. Iliac crest bone graft was used in 10 patients, and vascularised fibula graft in one patient. RESULTS The primary deformity affecting the radial diaphysis (R2) determined a secondary deformity in four patients: in the distal ulna (U3) with ulnocarpal dislocation in three patients and in the distal radius (R3) in one patient. Results of osteosynthesis treatment were excellent in one patient, satisfactory in four and unsatisfactory in one. External fixation was excellent in one patient and satisfactory in five. Bone resection was satisfactory in one patient. DISCUSSION Surgical treatments with osteosynthesis are the major cause of acquired forearm deformities in adults. Location and aetiology of the deformities are essential for the surgical indication and the result. It is important to restore the length of the deformed segment, realigning the anatomical axis. X-rays enable clinicians to distinguish between primary and secondary forearm deformities. CONCLUSION Characteristics and locations of post-traumatic deformities were identified. The major location is diaphisary and distal, the elbow is rarely affected. The functional consequence is a limitation in the range of motion of the hand. The best results are achieved with short-term treatment.

Abstract
OBJECTIVES The tibiofibular diastasis requires an appropriate surgical treatment in order not to run into negative results such as decreased range of motion and chronic instability. We have conducted a comparative study between the transfixation screw and a new technique based upon the reabsorbable cerclage, a less invasive technique. MATERIALS AND METHODS We enrolled 30 patients affected by tibiotarsal distortion with an acute lesion of the syndesmosis, and we divided them in 2 groups randomly. The first group of patients (15 cases) has been treated with a tricortical, or quadricortical syndesmotic screw, and the second group of patients (15 cases) has been treated with a tibiofibular cerclage with reabsorbing wires. The evaluation of the lesions was documented through comparative radiographies of the ankle in the AP, LL and mortise projections. RESULTS In group 1, we observed an excellent outcome in 4 patients, while in the remaining 11 cases there was evidence of alterations in the evaluated parameters. In group 2, we observed an excellent outcome in 6 patients, and only in half of the remaining cases it was found a slight alteration only when the articulation is stressed. CONCLUSIONS The main indications for the tibiofi bular cerclage are the syndesmotic lesions not associated to fi bular fractures. The achieved results support the validity of the cerclage technique, showing evidence of advantages concerning the functional recovery. The cerclage also allows to avoid the subsequent surgery required for the screw removal. Therefore the tibiofi bular cerclage represents a valid alternative to the treatment with the syndesmotic screw.

Abstract
The human and the murine glycoprotein platelet IIb (GPIIb) promoters are megakaryocyte specific in human and murine cell systems, respectively. Here we show that the murine promoter is, however, highly active when transfected in K562 human cells in which the human promoter is almost inactive. A murine promoter, in which the enhancer element was replaced by the human, retrieves its megakaryocytic specificity in human cell lines. The human and murine GATA-binding sites located in the enhancer region display slight sequence divergence next to the consensus GATA core sequence. Gel shift experiments show that, although the murine and the human GATA sequences both bind GATA-1, the murine sequence alone forms an additional complex (B) not detected with the human sequence. When the murine GATA-containing region is replaced by the human in the context of the murine GPIIb promoter, megakaryocyte specificity is restored in the human cell lines. A G nucleotide 3 to GATA appears crucial because its substitution abrogates B but not GATA-1 binding and restores megakaryocyte specificity to the murine promoter. Conversely, substitution of the human GATA-1 binding sequence by its murine homologue that binds both GATA-1 and complex B induces an abnormal activity for the human promoter in K562 cells. Altogether, our data suggest that limited changes in the GATA-containing enhancer of the GPIIb promoter can induce the recruitment of accessory proteins that could be involved in alteration of a megakaryocyte-restricted gene activation program.

Abstract
Road traffic accidents (RTAs) with entrapment are perceived as a challenge to emergency systems because of the severity of the ensuing traumas and the inherent complexity of the rescue procedures. To clarify these two aspects this prospective cohort study enrolling 244 entrapped trauma patients was conducted by a Regional Medical Helicopter Service. Forty-six victims (18.9%) were found dead, 101 (51%) of the 198 patients who reached the hospital alive had an injury severity score (ISS) > or = 16. The use of seat belts was associated with lower trauma severity. Out of the 101 severely traumatized patients (ISS > or = 16), 46 (42.6%) were intubated at road side, 12 required decompression of a tension pneumothorax on the scene and in 15 cases a pneumothorax was drained during the early intrahospital phase. Thirty-six (34.7%) patients had the first systolic blood pressure (SBP) < or = 90 mmHg and were then aggressively infused: in 75% of these cases, the SBP on arrival at the emergency department increased. The first SBP was significantly correlated with mortality. There was no correlation of extrication time, total rescue time and mortality. Fourteen patients (13.9%) died during hospitalization. These data demonstrate that a high percentage of entrapped patients require advanced life support (ALS), including on scene intubation and chest decompression. Aggressive field resuscitation and immediate transport to a level 1 trauma centre is associated with a mortality lower than that predicted by TRISS in spite of the prolonged prehospital time.

Abstract
PURPOSE In vitro synergy between cisplatin and irinotecan (CPT-11) has been reported. We designed a combination schedule of these agents to maximize the potential for synergistic interaction. PATIENTS AND METHODS To maximize the opportunity for synergy, we divided the cisplatin into four consecutive weekly treatments, followed by a 2-week rest. Each dose of cisplatin was immediately followed by a dose of irinotecan. The dose of cisplatin was fixed at 30 mg/m2/wk. The initial irinotecan dose was 50 mg/m2/wk and this was escalated by 30% increments in successive cohorts of three to six patients to establish the maximum-tolerated dose (MTD). Pharmacokinetics of irinotecan and its metabolites, SN-38 and SN-38 glucuronide (SN-38G), were analyzed. RESULTS Of 35 patients with solid tumors enrolled onto this trial, 30 were assessable for toxicity and response. The MTD for this regimen was 30 mg/m2/wk of cisplatin plus 50 mg/m2/wk of irinotecan in previously treated patients and 30 mg/m2/wk of cisplatin plus 65 mg/m2/wk of irinotecan in chemotherapy-naive patients. Neutropenia was the dose-limiting toxicity (DLT) encountered in this trial. Diarrhea was infrequent and rarely dose-limiting. Seven of 30 assessable patients achieved a partial response. No alteration in irinotecan, SN-38, or SN-38G pharmacokinetics resulted from the administration of cisplatin with irinotecan. CONCLUSION The administration of cisplatin and irinotecan on this weekly schedule provides a practical and well-tolerated regimen that has the potential to maximize any clinical synergy between the two agents. Evidence of substantial clinical activity was seen in this phase I study.
