Abstract
In this paper, the effects of four cooking procedures were evaluated, two occurring in atmospheric (in ventilated and steam oven) and two in subatmospheric (vacuum and sous vide cooking) conditions on pork Longissimus lumborum. The main objective of the study was to compare and evaluate the physical and chemical characteristics. Samples were cooked in four independent trials namely Oven (O), Steaming (ST), Vacuum Cooking (VC) and Sous Vide (SV). The analyses included temperature, cooking effect, percentage weight loss, texture (cutting and double compression tests), colour (superficially and inside the sample), microstructure (optical microscopy) and fibres shortening analysis. To assess cooking effects on significant nutritional constituents, the fatty acid composition and the content of B vitamins were analysed. Volatile profiles of samples were also compared using solid-phase microextraction. SV cooking resulted in the less favourable meat texture, presenting the highest hardness and chewiness. Moreover, high hardness values measured on SV samples is also related to the high weight loss. The technique of oven cooking (O) demonstrated superior results in terms of mechanical properties, which are closely associated with the cooking values. Specifically, the cook value C0 was significantly higher in the case of oven cooking compared to SV, VC, and ST. Mild temperature conditions and cooking times of the four considered cooking techniques did not induce significant variations in the fatty acid composition and volatile profile. Conversely, SV and VC allowed the highest amount of vitamin B retention in cooked meat. This work suggests that some differences emerged on the effects due to sub-atmospheric and atmospheric cooking compared to traditional ones.

Abstract
BACKGROUND Oncologic outcomes after laparoscopic gastrectomy for advanced gastric cancer in the West have been poorly investigated. The aim of the present study was to compare survival outcomes in patients undergoing curative-intent laparoscopic and open gastrectomy for advanced gastric cancer in several centres belonging to the Italian Research Group for Gastric Cancer. METHODS Data of patients operated between 2015 and 2018 were retrospectively analysed. Propensity Score Matching was performed to balance baseline characteristics of patients undergoing laparoscopic and open gastrectomy. The primary endpoint was 3-year overall survival. Secondary endpoints were 3-year disease-free survival and short-term outcomes. Multivariable regression analyses for survival were conducted. RESULTS Data were retrieved from 20 centres. Of the 717 patients included, 438 patients were correctly matched, 219 per group. The 3-year overall survival was 73.6% and 68.7% in the laparoscopic and open group, respectively (p = 0.40). When compared with open gastrectomy, laparoscopic gastrectomy showed comparable 3-year disease-free survival (62.8%, vs 58.9%, p = 0.40), higher rate of return to intended oncologic treatment (56.9% vs 40.2%, p = 0.001), similar 30-day morbidity/mortality. Prognostic factors for survival were ASA Score ≥ 3, age-adjusted Charlson Comorbidity Index ≥ 5, lymph node ratio ≥ 0.15, p/ypTNM Stage III and return to intended oncologic treatment. CONCLUSIONS Laparoscopic gastrectomy for advanced gastric cancer offers similar rates of survival when compared to open gastrectomy, with higher rates of return to intended oncologic treatment. ASA score, age-adjusted Charlson Comorbidity Index, lymph node ratio, return to intended oncologic treatment and p/ypTNM Stage, but not surgical approach, are prognostic factors for survival.

Abstract
Despite the fact that peptide conjugates with a pendant ferrocenyl (Fc) have been widely investigated, bis-ferrocenyl end-capped peptides are rarely synthetized. In this paper, in addition to the full characterization of the Fc-CO-[L-Dap(Boc)]n-NH-Fc series, we report a comparison of the three series of bis-ferrocenyl homopeptides synthesized to date, to gain insights into the influence of α-amino isobutyric (Aib), 2,3-diamino propionic (Dap) and Cα,β-didehydroalanine (ΔAla) amino acids on the peptide secondary structure and on the ferrocene redox properties. The results obtained by 2D NMR analysis and X-ray crystal structures, and further supported by electrochemical data, evidence different behaviors depending on the nature of the amino acid; that is, the formation of 310-helices or fully extended (2.05-helix) structures. In these foldamers, the orientation of the carbonyl groups in the peptide helix yields a macrodipole with the positive pole on the N-terminal amino acid and the negative pole on the C-terminal amino acid, so that oxidation of the Fc moieties takes place more or less easily depending on the orientation of the macrodipole moment as the peptide chain grows. Conversely, the fully extended conformation adopted by ΔAla flat peptides neither generates a macrodipole nor affects Fc oxidation. The utilization as electrochemical and optical (Circular Dichroism) probes of the two terminal Fc groups, bound to the same peptide chain, makes it possible to study the end-to-end effects of the positive charges produced by single and double oxidations, and to evidence the presence "exciton-coupled" CD among the two intramolecularly interacting Fc groups of the L-Dap(Boc) series.

Abstract
BACKGROUND Current dietary guidelines recommend five or more fruit, vegetable, and legume servings per day. Often, these products are eaten cooked, resulting in organoleptic and nutritional changes. Vacuum cooking is gaining attention as an alternative cooking technique, due to its ability to preserve or even enhance sensory and healthy properties of food. Its household application is, however, poorly explored. In this work, the effect of vacuum cooking, performed with a new patented system, was studied for the first time on pumpkin cubes and compared to sous vide and traditional steam cooking, through a multidisciplinary approach. RESULTS All the cooking treatments damaged pumpkin microstructure, leading to cell separation and plasmolysis; vacuum cooking was the most aggressive method, as confirmed by texture softening. Vacuum cooking was also the method with less impact on pumpkin color, in relation to the largest extraction of some classes of carotenoids from the broken cells. Significant polyphenol extraction, especially of gallic acid and naringenin, was instead observed for sous vide and steamed pumpkins. The total antioxidant activity, ascribable to the effect of both carotenoids and polyphenols, resulted enhanced after cooking compared to raw one mainly for cook vide samples, followed by steamed and sous vide ones. CONCLUSIONS Vacuum cooking, followed by sous vide, has often shown better performance than traditional steam cooking for pumpkin cubes. The implementation of sous vide and vacuum cooking at domestic level or in professional kitchens, and in the food industry, would allow the consumption of vegetables with improved nutritional and sensorial characteristics. © 2020 Society of Chemical Industry.

Abstract
The foldamer field is continuously expanding as it allows to produce molecules endowed with 3D-structures and functions never observed in nature. We synthesized flat foldamers based on the natural, but non-coded, Cα,β -didehydroalanine α-amino acid, and covalently linked to them two ferrocene (Fc) moieties, as redox probes. These conjugates retain the flat and extended conformation of the 2.05 -helix, both in solution and in the crystal state (X-ray diffraction). Cyclic voltammetry measurements agree with the adoption of the 2.05 -helix, characterized by a negligible dipole moment. Thus, elongated α-peptide stretches of this type are insulators rather than charge conductors, the latter being constituted by peptide α-helices. Also, our homo-tetrapeptide has a N-to-C length of about 18.2 Å, almost double than that (9.7 Å) of an α-helical α-tetrapeptide.

Abstract
Quartered Violetto artichokes were cooked with different treatments (boiling, steaming, sous vide and vacuum cooking) at the same cooking value at the thermal centre. Then, the physical (moisture content, texture and colour), histological and chemical (phenolic, 5-hydroxymethylfurfural (HMF) and furan content, total antioxidant capacity) features of bracts and hearts were assessed. A deeply modified microstructure was observed in boiled and steamed samples with an evident decrease in hardness both for bracts and hearts. Lightness of two anatomical parts was decreased by all the treatments (with the exception of sous vide bracts). The highest total colour difference was recorded for steamed samples, whereas the lowest was noted for sous vide samples. Steamed and sous vide artichoke exhibited the highest total phenolic content and total antioxidant capacity. Sous vide samples exhibited the highest concentrations of HMF, 2-furan-methanol and 2,4-dihydroxy-2,5-dimetyl-3(2H)-furanone, whereas the by-product 5-metylfuraldheide was only detected in the steamed product.

Abstract
Laparoscopic Heller myotomy and Dor fundoplication is considered a safe and effective treatment for achalasia. Robotic-assisted Heller-Dor procedure (RAHD) has emerged as an alternative approach due to improved visualization and fine motor control. The aim of this prospective study was to evaluate clinical, and functional results of RAHD. We evaluated a group of 66 patients with achalasia that underwent robotic-assisted Heller-Dor operation. Before treatment all patients underwent a diagnostic work-up such as upper endoscopy, esophageal barium swallow and high resolution manometry. The presence of postoperative gastroesophageal reflux disease was diagnosed by impedance and pH monitoring (MII-pH). Dysphagia improved in 92.4% of patients after treatment. Barium swallow series showed esophageal emptying in 100% of patients and a significant reduction of the esophageal diameter (p = 0.00235). Forty-five of 66 patients (68.2%) underwent upper endoscopy and 35 of 66 (53%) underwent MII-pH. Esophageal erosions were found in 4/45 (8,8%) and MII-pH showed abnormal results in 3/35 patients (8.6%). RAHD ensures a meticulous esophageal and gastric myotomy, allowing to visualize and divide each muscle fibers with a low rate of intraoperative and postoperative complications. resulting in turn in good clinical outcomes, radiological findings and functional results even if robotic tecnique definitely increases the surgical cost in the treatment of these functional esophageal disorders.

Abstract
Considering the crude methods used to control phytoplasma diseases, a deeper knowledge on the defence mechanisms recruited by the plant to face phytoplasma invasion is required. Recently, we demonstrated that Arabidopsis mutants lacking AtSEOR1 gene showed a low phytoplasma titre. In wild type plants AtSEOR1 and AtSEOR2 are tied in filamentous proteins. Knockout of the AtSEOR1 gene may pave the way for an involvement of free AtSEOR2 proteins in defence mechanisms. Among the proteins conferring resistance against pathogenic bacteria, AtRPM1-interacting protein has been found to interact with AtSEOR2 in a high-quality, matrix-based yeast-two hybrid assay. For this reason, we investigated the expression levels of Arabidopsis AtRIN4, and the associated AtRPM1 and AtRPS2 genes in healthy and Chrysanthemum yellows-infected wild-type and Atseor1ko lines.

Abstract
Collagen VI is a microfibrillar collagen with a potential regulatory role in tendon repair mechanism. We studied the expression of collagen VI α5 and α6 chains in normal human tendon fibroblast cultures, both under basal condition and in response to TGF-β1, a potent regulator of tendon healing. Under basal condition, we found that the α5 chain was expressed, although to a lesser extent with respect to the α3 chain; in contrast, the α6 chain was absent. The treatment with TGFβ1 induced an opposite effect on the expression of the α5 and α6 chains; in fact, while the α5 chain was dramatically reduced, the α6 chain was induced and released in the culture medium. These data indicate that collagen VI α5 and α6 chains are differentially involved in tendon matrix homeostasis. The α6 chain may represent a new potential biomarker for monitoring TGFβ1-related events in tendon, as healing and fibrotic scar formation.

Abstract
Callose deposition, phloem-protein conformational changes and cell wall thickening are calcium-mediated occlusions occurring in the plant sieve elements in response to different biotic and abiotic stresses. However, the significance of these structures in plant-phytoplasma interactions requires in-depth investigations. We adopted a novel integrated approach, based on the combined use of microscopic and molecular analyses, to investigate the structural modifications induced in tomato leaf tissues in presence of phytoplasmas, focusing on vascular bundles and on the occlusion structures. Phloem hyperplasia and string-like arrangement of xylem vessels were found in infected vascular tissue. The diverse occlusion structures were differentially modulated in the phloem in response to phytoplasma infection. Callose amount was higher in midribs from infected plants than in healthy ones. Callose was observed at sieve plates but not at pore-plasmodesma units. A putative callose synthase gene encoding a protein with high similarity to Arabidopsis CalS7, responsible for callose deposition at sieve plates, was upregulated in symptomatic leaves, indicating a modulation in the response to stolbur infection. P-proteins showed configuration changes in infected sieve elements, exhibiting condensation of the filaments. The transcripts for a putative P-protein 2 and a sieve element occlusion-related protein were localized in the phloem but only the first one was modulated in the infected tissues.

Abstract
In this article, the successful preparation of a new series of 3(10) -helical peptides of different length containing two terminal ferrocenyl (Fc) units and based on the strongly foldameric α-aminoisobutyric (Aib) acid is reported. The synthesis of the Fc-CO-(Aib)(n) -NH-Fc (n = 1-5) homo-peptides was performed by solution methods. Moderate to good yields (26-85%) were obtained in each of the difficult coupling steps of Fc-COOH and the corresponding H-(Aib)(n)-NH-Fc compounds by C-activation with the 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide/7-aza-1-hydroxy-1,2,3-benzotriazole method. Information on the C=O···H-N intramolecularly hydrogen-bonded networks was initially obtained from FT-IR absorption measurements. The N-H stretching (amide A) region allowed us to distinguish which amide protons are involved in intramolecular hydrogen bonds and indicates the formation of an incipient 3(10) -helix structure for peptides containing at least two Aib residues. This conclusion was confirmed by (1)H NMR titrations of the N-H groups of the peptides in CDCl(3) with dimethylsulfoxide and by crystallographic analysis of the N(α) -acylated Fc-CO-(Aib)(5)-NH-Fc pentapeptide amide. The two redox-active Fc groups covalently bound to the termini of the foldameric peptide architectures were used as electrochemical probes. The end-to-end effects of electron holes generated by single and double oxidations were analyzed by means of electrochemical and spectroelectrochemical techniques. The results of these studies indicate that charge transfer across the peptide main chain does occur in the five peptides. In particular, in the pentapeptide 5, charge is transferred through an intramolecular Fe···Fe separation of 14 Å.

Abstract
Collagen VI is a non-fibrillar collagen present in the extracellular matrix (ECM) as a complex polymer; the mainly expressed form is composed of α1, α2 and α3 chains; mutations in genes encoding these chains cause myopathies known as Ullrich congenital muscular dystrophy (UCMD), Bethlem myopathy (BM) and myosclerosis myopathy (MM). The collagen VI α6 chain is a recently identified component of the ECM of the human skeletal muscle. Here we report that the α6 chain was dramatically reduced in skeletal muscle and muscle cell cultures of genetically characterized UCMD, BM and MM patients, independently of the clinical phenotype, the gene involved and the effect of the mutation on the expression of the “classical” α1α2α3 heterotrimer. By contrast, the collagen VI α6 chain was normally expressed or increased in the muscle of patients affected by other forms of muscular dystrophy, the overexpression matching with areas of increased fibrosis. In vitro treatment with TGF-β1, a potent collagen inducer, promoted the collagen VI α6 chain deposition in the ECM of normal muscle cells, whereas, in cultures derived from collagen VI-related myopathy patients, the collagen VI α6 chain failed to develop a network outside the cells and accumulated in the endoplasmic reticulum. The defect of the α6 chain points to a contribution to the pathogenesis of collagen VI-related disorders. Collagen VI is an ECM component of the human skeletal muscle. We evaluated the α6 chain in collagen VI-related and other muscular dystrophies. The α6 chain was reduced in collagen VI-related diseases but not in other myopathies. A correlation between the α6 chain and fibrosis was demonstrated in MDC1A. The α6 chain is involved in the pathogenesis of collagen VI diseases and fibrosis.

Abstract
The use of protein cross-linking agents during bonding procedures has been recently proposed to improve bond durability. This study aimed to use zymography and in situ zymography techniques to evaluate the ability of 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) cross-linker to inhibit matrix metalloproteinase (MMP) activity. The hypotheses tested were that: (1) bonding procedures increase dentin gelatinolytic activity and (2) EDC pre-treatment prevents this enzymatic activity. The zymographic assay was performed on protein extracts obtained from dentin powder treated with Optibond FL or Scotchbond 1XT with or without 0.3M EDC pre-treatment. For in situ zymography, adhesive/dentin interfaces were created with the same adhesives applied to acid-etched dentin slabs pre-treated or not with EDC conditioner. Zymograms revealed increased expression of dentin endogenous MMP-2 and -9 after adhesive application, while the use of EDC as a primer inactivated dentin gelatinases. Results of in situ zymograpy showed that hybrid layers of tested adhesives exhibited intense collagenolytic activity, while almost no fluorescence signal was detected when specimens were pre-treated with EDC. The correlative analysis used in this study demonstrated that EDC could contribute to inactivate endogenous dentin MMPs within the hybrid layer created by etch-and-rinse adhesives.

Abstract
Multiphoton absorptions are important non-linear optical processes which allow us to explore excited states with low energy photons giving rise to new possibilities for photoinduced processes. Among these processes, multiphoton absorptions from excited states are particularly interesting because of the large susceptibilities characteristic of excited states. Here we explore the nonlinear transmission measurements recorded with 9 ns laser pulses at 1064 nm of the radical cations of (2-ferrocenyl)indene and of (2-ferrocenyl)-hexamethylindene, two interesting very stable molecules. The non-linear transmission data can be interpreted with a multiphoton sequence of three photon absorptions, the first being a one photon absorption related to the intramolecular charge transfer and the second a two photon absorption from the excited state created with the first process. The two photon absorption cross section is found to be several orders of magnitude larger than those usually found for two photon absorbing systems excited from the ground state.

Abstract
Mesenchymal stem cells (MSC) have the unique ability to home and engraft in tumor stroma. These features render them potentially a very useful tool as targeted delivery vehicles which can deliver therapeutic drugs to the tumor stroma. In the present study, we investigate whether fluorescent core-shell PMMA nanoparticles (FNPs) post-loaded with a photosensitizer, namely meso-tetrakis (4-sulfonatophenyl) porphyrin (TPPS) and uploaded by MSC could trigger osteosarcoma (OS) cell death in vitro upon specific photoactivation. In co-culture studies we demonstrate using laser confocal microscopy and time lapse imaging, that only after laser irradiation MSC loaded with photosensitizer-coated fluorescent NPs (TPPS@FNPs) undergo cell death and release reactive oxygen species (ROS) which are sufficient to trigger cell death of all OS cells in the culture. These results encourage further studies aimed at proving the efficacy of this novel tri-component system for PDT applications.

Abstract
Saporin-S6 is a single-chain ribosome-inactivating protein (RIP) that has low toxicity in cells and animals. When the protein is bound to a carrier that facilitates cellular uptake, the protein becomes highly and selectively toxic to the cellular target of the carrier. Thus, saporin-S6 is one of the most widely used RIPs in the preparation of immunoconjugates for anti-cancer therapy. The endocytosis of saporin-S6 by the neoplastic HeLa cells and the subsequent intracellular trafficking were investigated by confocal microscopy that utilises indirect immunofluorescence analysis and transmission electron microscopy that utilises a direct assay with gold-conjugated saporin-S6 and an indirect immunoelectron microscopy assay. Our results indicate that saporin-S6 was taken up by cells mainly through receptor-independent endocytosis. Confocal microscopy analysis showed around 30% co-localisation of saporin-S6 with the endosomal compartment and less than 10% co-localisation with the Golgi apparatus. The pathway identified by the immunofluorescence assay and transmission electron microscopy displayed a progressive accumulation of saporin-S6 in perinuclear vesicular structures. The main findings of this work are the following: i) the nuclear localisation of saporin-S6 and ii) the presence of DNA gaps resulting from abasic sites in HeLa nuclei after intoxication with saporin-S6.

Abstract
Two series of 3(10)-helical peptides of different lengths and rigidity, based on the strongly foldameric α-aminoisobutyric acid and containing a terminal ferrocenyl unit, have been synthesized. Oxidation-state sensitive spectroscopic tags of helical peptides, the N-H groups, allowed mapping of the charge delocalization triggered by oxidation of the terminal ferrocenyl moiety and were monitored by IR spectroelectrochemistry.

Abstract
Immunosuppressive treatment has changed the prognosis of Lupus nephritis over time, but improvement in prognosis is difficult to analyze in different historical periods, and should be better demonstrated in comparison with life expectancy of sex-and age-matched people. Long-term patient and renal survival of 90 patients diagnosed with Lupus nephritis at our center from 1968 to 2001 with a follow-up time of 14±8 years was retrospectively evaluated. Patient and kidney survival significantly increased over time. Multivariate analyses show that risks of patient and renal death decreased by 8% at each year of follow-up, and increased by more than 5 time in patients aged > 30 years at diagnosis. As only 14 patients were men, relative survival as compared to that of the sex- and age-matched general population of the Piedmont Region was calculated for the 76 women. Improvement in the survival of the cohort of women was seen at any time of follow-up: in particular, it was sharply lower in the first period (relative survival at 5,10 and 15 years = 0.784, 0.665, and 0.620, respectively) and increased in the second (relative survival at 5,10 and 15 years = 0.939, 0.921, and 0.850, respectively) nearly approaching that expected for the general population, i.e. 0.993, 0.983 and 0.967, respectively. Taken together, our data allow us to draw the conclusion that life expectancy in women with Lupus nephritis has improved over time, paralleling an improved awareness of the disease and a significant increase in steroid pulse therapy as induction/remission phase. Improvement in survival is for the first time demonstrated to cover the gap with life expectancy of the general population for women with Lupus nephritis.

Abstract
Sucralfate is a drug used in the treatment of gastric and duodenal ulcer; it is cytoprotective and able to increase the bioavailability of several growth factors, modulating the wound healing process. In this study we tested the possible therapeutic effect of Sucralfate in the treatment of ulcerative lesions occurring in uterine cervix; to investigate such effect we used an experimental rat model of cervicitis in which the uPAR and EGFR expression were evaluated. Cervicitis was induced in wild and ovariectomized Wistar female rats by an acetic acid-soaked tampon. The animals were divided into two main groups (4 and 7 days) and Sucralfate was administered topically until the day they were sacrificed. In order to distinguish physiological and drug-induced healing, quantitative and qualitative uPAR and EGFR expression were evaluated by using Western blot and Immunohistochemistry techniques. Western blot analysis demonstrated an increased expression of both receptors after 4 days from wounding in wild and ovariectomized animals. In particular in ovariectomized animals the expression of uPAR and EGFR increased after 4 days while it reduced following the administration of Sucralfate. In wild rats the same was observed for uPAR expression, while EGFR was different; in fact, its expression increased significantly at day 4 in the animals treated with the drug and only at day 7 in those untreated. Immunohistochemistry highlighted a noteworthy epithelial colocalization of EGFR and uPAR after 4 days in the animals treated with Sucralfate. We conclude that Sucralfate can promote the healing of ulcerative cervicitis and moreover, it reduces the normal healing time because of its modulatory property on uPAR and EGFR expression.

Abstract
The risk of an avian influenza pandemic has put oseltamivir (Tamiflu) in the spotlight and has given rise to rumors that shikimic acid (SK), which is used for the synthesis of Tamiflu, possesses therapeutic activity. This study was undertaken to determine whether SK, either alone or in combination with quercitin (QT) is able to modulate the release of IL-6 and IL-8 from peripheral blood mononuclear cells (PBMCs). The experiments were conducted comparing the properties of SK, both alone and in combination, with those of Tamiflu. The incubation of PBMCs with 100 nM Tamiflu or SK at two concentrations (10 nM; 100 nM) did not produce any change in IL-6 and IL-8 baseline levels (data expressed as incremental change vs. baseline). On the contrary, incubation with SK and QT at both concentrations (10 and 100 nM) produced a significant increase in the release of IL-8 as compared to other groups (4.19 +/- 0.82, SK-QT 10 nM; 3.83 +/- 1.17 SK-QT 100 nM, P < 0.05 vs. baseline 1.00 +/- 0.10, Tamiflu 100 nM 1.35 +/- 0.16, SK 10 nM 1.68 +/- 0.15 and SK 100 nM 1.80 +/- 0.48). The SK-QT combination also proved to be effective in the upregulation of IL-6 (3.08 +/- 0.46, SK-QT 10 nM; 3.60 +/- 0.74 SK-QT 100 nM, P < 0.05 vs. baseline 1.00 +/- 0.26). According to these findings SK alone is not able to modulate innate immunity in antiviral terms. However, the data show that the SK + QT combination, even at low doses, may be effective for the modulation of innate immunity.
