Abstract
BACKGROUND Peanut allergy has a rising prevalence in high-income countries, affecting 0.5%-1.4% of children. This study aimed to better understand peanut anaphylaxis in comparison to anaphylaxis to other food triggers in European children and adolescents. METHODS Data was sourced from the European Anaphylaxis Registry via an online questionnaire, after in-depth review of food-induced anaphylaxis cases in a tertiary paediatric allergy centre. RESULTS 3514 cases of food anaphylaxis were reported between July 2007 - March 2018, 56% in patients younger than 18 years. Peanut anaphylaxis was recorded in 459 children and adolescents (85% of all peanut anaphylaxis cases). Previous reactions (42% vs. 38%; p = .001), asthma comorbidity (47% vs. 35%; p < .001), relevant cofactors (29% vs. 22%; p = .004) and biphasic reactions (10% vs. 4%; p = .001) were more commonly reported in peanut anaphylaxis. Most cases were labelled as severe anaphylaxis (Ring&Messmer grade III 65% vs. 56% and grade IV 1.1% vs. 0.9%; p = .001). Self-administration of intramuscular adrenaline was low (17% vs. 15%), professional adrenaline administration was higher in non-peanut food anaphylaxis (34% vs. 26%; p = .003). Hospitalization was higher for peanut anaphylaxis (67% vs. 54%; p = .004). CONCLUSIONS The European Anaphylaxis Registry data confirmed peanut as one of the major causes of severe, potentially life-threatening allergic reactions in European children, with some characteristic features e.g., presence of asthma comorbidity and increased rate of biphasic reactions. Usage of intramuscular adrenaline as first-line treatment is low and needs to be improved. The Registry, designed as the largest database on anaphylaxis, allows continuous assessment of this condition.

Abstract
The well-being of dogs can be affected by changes in human lifestyle, eating habits and increased stressors that lead to behavioural disorders including fear, hyperactivity and anxiety, followed by negative affective moods and poor welfare. This randomised, controlled clinical evaluation involved 69 dogs, 38 males and 31 females, of different breeds, with behavioural disorders related to anxiety and chronic stress. They were fed a control diet or a nutraceutical diet (ND group) for 45 days. Neuroendocrine (serotonin, dopamine, β-endorphins, noradrenaline and cortisol) and stress (derivatives of reactive oxygen metabolites (dROMs) and biological antioxidant potential (BAP)) parameters related to behavioural disorders were evaluated at the beginning and end of the study period. Results showed a significant increase in serotonin, dopamine and β-endorphins plasma concentrations (*P<0.05, *P<0.05 and **P<0.01, respectively) and a significant decrease in noradrenaline and cortisol plasma concentrations in the ND group (*P<0.05). dROMs significantly decreased in the ND group (*P<0.05) while BAP was not affected. This study demonstrated for the first time that a specific diet significantly and positively affected neuroendocrine parameters and dROMs. These results open significant perspectives concerning the use of diet and nutraceuticals in the treatment of behavioural disorders.

Abstract
Several concerns have been raised over the health of animals used in equestrian games that have their origins in historical or religious events and are currently held in many countries. This study investigated physiological stress response and health status of horses participating in the Sartiglia, a historical horse tournament held in the city of Oristano, Italy, which is principally based on the attempts of masked horsemen at a gallop to run a sword through a hole in a suspended silver star. Blood samples were collected from 21 horses the day before the tournament (D0), during the tournament (D1), and the day after the tournament (D2). Samples were analyzed for complete blood count and biochemical, hormonal, and oxidative stress assays. Data were analyzed using the mixed effect model with sampling session as one of the fixed effects. On the whole, blood parameters evidenced an optimal health status of horses at D0. Significant dehydration and increase of circulating glucose, enzymes, cortisol, and β-endorphin were registered at D1 (P < 0.001) with a complete recovery of physiological values just at D2. The reactive oxygen metabolites (d-ROM), from which the prooxidant activity can be evaluated, showed an increase from D0 to D1 and D2. Concentration of biological antioxidant potential, which measured the antioxidant capacity, was characterized by the maximum level registered during the tournament and counteracted the simultaneous increase of d-ROM. It can be hypothesized that the tournament played an important role in causing high levels of oxidant markers not only because of the physical exercise represented by the gallop but also because the emotional stressors. In conclusion, the tournament caused significant changes of most parameters, which rapidly recovered to baseline values within the day after. These data will certainly be useful for a future implementation of tests in equine medicine and for the improvements of knowledge of changes of blood parameters and health of horses in similar tournaments.

Abstract
BACKGROUND : Probiotic administration has been proposed for the prevention and treatment of specific allergic manifestations such as eczema, rhinitis, gastrointestinal allergy, food allergy, and asthma. However, published statements and scientific opinions disagree about the clinical usefulness. OBJECTIVE : A World Allergy Organization Special Committee on Food Allergy and Nutrition review of the evidence regarding the use of probiotics for the prevention and treatment of allergy. METHODS : A qualitative and narrative review of the literature on probiotic treatment of allergic disease was carried out to address the diversity and variable quality of relevant studies. This variability precluded systematization, and an expert panel group discussion method was used to evaluate the literature. In the absence of systematic reviews of treatment, meta-analyses of prevention studies were used to provide data in support of probiotic applications. RESULTS : Despite the plethora of literature, probiotic research is still in its infancy. There is a need for basic microbiology research on the resident human microbiota. Mechanistic studies from biology, immunology, and genetics are needed before we can claim to harness the potential of immune modulatory effects of microbiota. Meanwhile, clinicians must take a step back and try to link disease state with alterations of the microbiota through well-controlled long-term studies to identify clinical indications. CONCLUSIONS : Probiotics do not have an established role in the prevention or treatment of allergy. No single probiotic supplement or class of supplements has been demonstrated to efficiently influence the course of any allergic manifestation or long-term disease or to be sufficient to do so. Further epidemiologic, immunologic, microbiologic, genetic, and clinical studies are necessary to determine whether probiotic supplements will be useful in preventing allergy. Until then, supplementation with probiotics remains empirical in allergy medicine. In the future, basic research should focus on homoeostatic studies, and clinical research should focus on preventive medicine applications, not only in allergy. Collaborations between allergo-immunologists and microbiologists in basic research and a multidisciplinary approach in clinical research are likely to be the most fruitful.

Abstract
Double-blind, placebo-controlled food challenges (DBPCFC) are the gold standard method for diagnosing food allergies. However, due to the difficulty of their performance on routine clinic, there is a need for laboratory tools in order to minimise the frequency of DBPCFC. Atopy patch test (APT) represents a promising manner of diagnosing delayed-type allergic reactions. The APT may identify patients with food allergies with negative specific IgE. However, the clinical relevance of positive APT reactions is still to be proven by standardised outcome definitions.

Abstract
Malignant mixed Müllerian tumor (MMMT) is a rare neoplasm of the female genital tract. We report a case of bilateral ovarian MMMT in a 10-year-old female dog. Ovaries were only moderately enlarged with a papillary surface and firm nodules. Multiple metastases were observed in the abdominal cavity and pulmonary parenchyma. Histologically, both ovaries had intermingled carcinomatous and sarcomatous components with cartilage and bone. Metastatic lesions were not mixed. The peritoneal metastases were carcinomatous; pulmonary metastases were sarcomatous. Carcinomatous elements of the MMMT were immunohistochemically positive for cytokeratin (CK) AE1/AE3, CK7, and vimentin and estrogen receptors. Conversely, the sarcomatous cells were positive for vimentin, but negative for CKs. Chondrocytes also expressed S-100 protein. On the basis of similarities to human ovarian MMMT, the diagnosis was heterologous malignant mixed Müllerian tumor of the ovary.

Abstract
In this case report, an atypical clinical presentation of leishmaniosis in a dog with multiple nodular lesions of the tongue is described. Haematological and biochemical analysis, serological test for Leishmania infantum antibodies and biopsy samples from several nodules of the tongue for histopathological examination were made. The final diagnosis of leishmaniosis was based upon the observation of amastigotes in the bioptic samples. It is recommended to consider leishmaniosis among the list of differentials of mucosal nodular lesions, at least in endemic areas.

Abstract
Ehrlichiosis and rickettsiosis are very common, widespread diseases. These diseases are present in Sardinia year round because its temperate weather permits the survival of many kinds of tick vectors. A thousand dogs were subjected to physical, hematological, biochemical examinations and serological tests. All 1,000 sera were analyzed by indirect immunofluorescence antibody test to detect antibodies against E. canis and R. rickettsii. A high seroprevalence (about 50%) was detected for both etiological agents, without differences in relation to sex, breed, or usage. A high seroprevalence, corresponding to 62.5% for ehrlichiosis and 64% for rickettsiosis, was observed in the age group of 13-60 months. The mortality was greatest in the males in the age group, which manifested the disease in the chronic phase.

Abstract
An N-capping box and a hydrophobic staple motif are strictly conserved in the core of all known glutathione S-transferases (GST). In the present work, mutations of hGSTA1-1 enzyme residues forming these motifs have been generated. The analysis of S154A, D157A, and S154A/D157A capping mutants indicate that the removal of this local signal destabilizes the protein. The fact that the third helical residue D157A mutation (N-3) was much more destabilizing than the first helical residue S154A mutation (N-cap) suggests that the appropriate conformation of the conserved substructure formed by the alpha 6-helix and preceding loop (GST motif II) is crucial for the overall protein stability. The refolding study of GSTA1-1 variants supports the prediction that this subdomain could represent a nucleation site of refolding. The analysis of L153A, I158A, L153G, and L153A/I158A hydrophobic staple mutants indicate that the removal of this motif destabilizes the GSTA1-1 structure as well as its refolding transition state. The hydrophobic staple interaction favors essential inter-domain contacts and, thereby, in contrast to capping interactions, accelerates the enzyme reactivation. Its strict conservation in the GST system supports the suggestion that this local signal could represent an evolutionarily conserved determinant for rapid folding.

Abstract
Five peptides matching the helices alpha4, alpha5, alpha6, alpha7, and alpha8, spanning the entire sequence of domain II of pG-STP1-1, have been synthesized and their conformations analyzed by far-UV CD spectroscopy. The results show that a5, a7, and a8 peptides are unstructured in water/2,2,2-trifluoroethanol (TFE) solutions. The a4-peptide also adopts random conformations in aqueous solvent. Moreover, the relative low helical content (20%), estimated for this peptide in the presence of 30% (v/v) TFE, suggests that the sequence of this protein fragment does not possess sufficient information for a strong helical propensity. On the contrary, the synthesized a6 peptide, in the presence of TFE, showed a relevant structural autonomy with a helical content (41%) which was significantly higher than that estimated, under the same conditions, for all other peptides. More in general in the presence of solvents less polar than water, the isolated a6 peptide shows the same helical conformation adopted by the corresponding alpha6-helix in the hydrophobic core of the protein. A n-capping box motif, strictly conserved at the N-terminal of the alpha6-helix of all GST and related protein including eucaryotic translation elongation factor (EF1gamma) and the yeast prion protein Ure2, plays an important role in the alpha-helix nucleation and stability of this protein fragment. The results suggest that the alpha6-helix might represent a nucleation site of GST folding and that the helical conformation of this region of the protein is an important requirement during earlier events of GST refolding.

Abstract
An N-capping box motif (Ser/Thr-Xaa-Xaa-Asp) is strictly conserved at the beginning of helix alpha6 in the core of virtually all glutathione transferases (GST) and GST-related proteins. It has been demonstrated that this local motif is important in determining the alpha-helical propensity of the isolated alpha6-peptide and plays a crucial role in the folding and stability of GSTs. Its removal by site-directed mutagenesis generated temperature-sensitive folding mutants unable to refold at physiological temperature (37 degrees C). In the present work, variants of human GSTP1-1 (S150A and D153A), in which the capping residues have been substituted by alanine, have been generated and purified for structural analysis. Thus, for the first time, temperature-sensitive folding mutants of an enzyme, expressed at a permissive temperature, have been crystallized and their three-dimensional structures determined by X-ray crystallography. The crystal structures of human pi class GST temperature-sensitive mutants provide a basis for understanding the structural origin of the dramatic effects observed on the overall stability of the enzyme at higher temperatures upon single substitution of a capping residue.

Abstract
The acid denaturation of human glutathione transferase P1-1 (hGSTP1-1) has been performed to investigate the unfolding intermediates of the protein and their possible involvement in the refolding mechanism. The acid-induced structures of GSTP1-1 have been characterized by activity, gel filtration, intrinsic fluorescence and far-u.v. circular dichroism (CD) techniques. Because of the non-identity of the different transitions monitored, the acid denaturation of hGSTP1-1 appears to be a multistep process during which several intermediates coexist in equilibrium. The dependence of inactivation on the protein concentration, as well as gel-filtration experiments, indicate that the inactivation transition, centred at about pH 4.0, corresponds to the monomerization of the protein. At pH 2.0, when the enzyme is completely inactive, the protein retains a small, but significant, amount of secondary structure. This means that the dimeric arrangement of the molecule is important for maintaining the native-like secondary structure of the monomer. The results show that, at low pH, the compact state of the GST monomer, even upon the addition of salts, does not possess native-like secondary structure as described for many monomeric proteins (molten globule). In the presence of physiological concentrations of salts, the protein solution at pH 2.0 leads to a dead-end aggregation process, suggesting that this compact state cannot represent a productive intermediate of the refolding pathway.

Abstract
Chronic airways inflammation in chronic obstructive pulmonary disease (COPD) induces the activation of several cell types with delivery of proteases and reactive oxygen species (ROS). Assessing oxidant content in the exhaled air of COPD patients has proven useful in monitoring airway inflammation. The present study was designed to confirm the usefulness of exhaled hydrogen peroxide concentration determination in COPD patients using a new technique which allows longer storage of the expired air condensate before the H2O2 assay. The technique was applied in 13 healthy nonsmoking subjects (six male, age range 22-40 yrs) and in seven patients (five male, age range 58-81 yrs) with mild or moderate COPD. Subjects breathed into a one-valve mouthpiece, and the exhaled air was directed into a vial kept at 0 degree C. After approximately 15 min of quiet breathing, 1 mL of expired air condensate was collected. An aliquot, 450 microL, of this sample was immediately added to an equal volume of a reaction mixture containing 2 mM 3,5,3',5'-tetramethylbenzidine and 40 microL of enzyme stock solution (0.5 mg.mL-1). After 15 min, 45 microL sulphuric acid was added (1 N final concentration), resulting in a reaction mixture pH of 1.0. After a further 10-min incubation, H2O2 concentration determination was performed spectrophotometrically at 450 nm. This solution, as well as the H2O2 assay, was stable for > or = 24 h if the sample was kept in the dark and at 4 degrees C. There was high stability on repeated measures, with a coefficient of variation equal to zero. The mean +/- SD H2O2 level in exhaled air from normal subjects was 0.12 +/- 0.09 microM, whereas it was significantly increased in COPD patients (0.50 +/- 0.11 microM; p = 0.0001 compared to healthy subjects). In three healthy control subjects, a normal H2O2 level in expired air increased to 0.70-0.80 microM during an acute upper respiratory tract infection. This new technique of hydrogen peroxide assay in expired air condensate greatly minimizes the inaccuracy deriving from the instability of hydrogen peroxide. The preliminary results obtained using this technique provide direct evidence for increased reactive oxygen species production in the airways of stable chronic obstructive pulmonary disease patients. However, the specificity of the procedure could be reduced by the interference of upper respiratory tract infections.

Abstract
The specific (i, i+5) hydrophobic staple interaction involving a helix residue and a second residue located in the turn preceding the helix is a recurrent motif at the N terminus of alpha-helices. This motif is strictly conserved in the core of all soluble glutathione transferases (GSTs) as well as in other protein structures. Human GSTP1-1 variants mutated in amino acid Ile(149) and Tyr(154) of the hydrophobic staple motif of the alpha6-helix were analyzed. In particular, a double mutant cycle analysis has been performed to evaluate the role of the hydrophobic staple motif in the refolding process. The results show that this local interaction, by restricting the number of conformations of the alpha6-helix relative to the alpha1-helix, favors the formation of essential interdomain interactions and thereby accelerates the folding process. Thus, for the first time it is shown that the hydrophobic staple interaction has a role in the folding process of an intact protein. In P(i) class GSTs, Tyr(154) appears to be of particular structural importance, since it interacts with conserved residues Leu(21), Asp(24), and Gln(25) of the adjacent alpha1-helix which contributes to the active site. Human GSTP1-1 variants L21A and Y154F have also been analyzed in order to distinguish the role of interdomain interactions from that of the hydrophobic staple. The experimental results reported here suggest that the strict conservation of the hydrophobic staple motif reflects an evolutionary pressure for proteins to fold rapidly.

Abstract
Recent studies have outlined the role of bisphosphonates, and particularly clodronate, as potential therapeutic agents for inflammatory and degenerative joint diseases. On this basis, we carried out an open, non comparative pilot trial to evaluate the effects of clodronate on synovial fluid concentration of some inflammatory mediators (prostaglandin E2, leukotriene B4 and tromboxane B2) after intra-articular, repeated administrations in 20 patients (7 males and 13 females) with synovitis secondary to knee osteoarthritis. At the end of the treatment period, statistically significant reductions (p < 0.05) of spontaneous pain and pain on active movement, evaluated by means of a 100 mm visual analogue scale (VAS), were reported. Linear regression analysis showed that the decrease of pain was correlated with the bisphosphonate induced reduction of prostaglandin E2 levels. These results, in spite of the limitation due to the open design of the trial suggest a possible role of bisphosphonates in the treatment of knee osteoarthritis.

Abstract
Here the structure of human glyoxalase II has been investigated by studying unfolding at equilibrium and refolding. Human glyoxalase II contains two tryptophan residues situated at the N-terminal (Trp57) and C-terminal (Trp199) regions of the molecule. Trp57 is a non-conserved residue located within a "zinc binding motif" (T/SHXHX57DH) which is strictly conserved in all known glyoxalase II sequences as well as in metal-dependent beta-lactamase and arylsulfatase. Site-directed mutagenesis has been used to construct single-tryptophan mutants in order to characterize better the guanidine-induced unfolding intermediates. The denaturation at equilibrium of wild-type glyoxalase II, as followed by activity, intrinsic fluorescence and CD, is multiphasic, suggesting that different regions of varying structural stability characterize the native structure of glyoxalase II. At intermediate denaturant concentration (1.2 M guanidine) a molten globule state is attained. The reactivation of the denatured wild-type enzyme occurs only in the presence of Zn(II) ions. The results show that Zn(II) is essential for the maintenance of the native structure of glyoxalase II and that its binding to the apoenzyme occurs during an essential step of refolding. The comparison of unfolding fluorescence transitions of single-trypthophan mutants with that of wild-type enzyme indicates that the strictly conserved "zinc binding motif" is located in a flexible region of the active site in which Zn(II) participates in catalysis.

Abstract
We describe 4 cases of malignant lymphoma (3 women, 1 man, age range 20-49 years) presenting with a tender and fusiform swelling at the level of the upper costosternal joints, with the clinical characteristics of classic Tietze's syndrome. Physical examination, laboratory findings and chest X-rays all were negative, while telethermography examination evidenced an area of hyperthermia at the level of the swelling in the chondrosternal region. Tietze's syndrome was diagnosed and the patients were treated with non-steroidal anti-inflammatory drugs and a local injection of corticosteroid. The clinical picture did not change, and in 2 cases a cervical lymphadenopathy developed. A biopsy of the lymph nodes and articular tumefaction disclosed Hodgkin's disease in 3 cases and non-Hodgkin's lymphoma in 1 case. Computerized tomography, lymphography and bone marrow biopsy permitted the complete staging of the lymphoma. After beginning a therapeutic program with chemotherapy and irradiation therapy, all 4 patients underwent complete remission.

Abstract
A group of 104 workers were examined. They were employed in selecting rags and separating the lining from wollen fabrics to be used again as thread waste in the textile industry. The aim of the study was to point out tendon and joint related disorders of the upper limb due to repetitive and forced movements. Twenty-eight (26.9%) workers complained of hand and wrist echography and thermography. In 19 patients (67.8%) clinical carpal tunnel syndrome was diagnosed. Eight workers (28.5%) had Dupuytren's contracture. Swelling of the fingers was found in 23 (82.1%). 14.2% and 28.5% of the workers showed respectively acro-osteolysis and acrosclerosis. The textile industry of Prato shows peculiar characters: the workers employed in selecting rags out a manual job which causes soft tissues and skeletal disorders in a great number of them. The acro-osteolytic and acrosclerotic changes of the fingers seem alike the bone disorders of chronic inflammatory rheumatic diseases as seronegative spondyloarthritis.

Abstract
A suitable enzyme sensor for the analysis of anticholinesterase compounds of pharmaceutical interest is described. It is based on the competitive inhibiting properties of these compounds on the enzyme butyrylcholinesterase and it is constituted by a hydrogen peroxide amperometric electrode modified by a superimposed Nylon membrane containing two chemically immobilized biological mediators (butyrylcholinesterase and choline oxidase). Some applications to the analysis of several pharmaceutical forms containing different compounds showing anticholinesterase activity are also reported and evaluated.

Abstract
An inherited defect os suppressor T-lymphocytes has been hypothesized in Hashimoto's thyroiditis. To assess this hypothesis, human T-lymphocyte subsets (TG, T lymphocytes with surface receptors for the Fc fragment of immunoglobulin G; TM, T lymphocytes with Fc receptor for immunoglobulin M) have been studied in nine patients affected by the disease. To cells have been previously shown to be suppressors in the pokeweed mitogen-stimulated B-cell differentiation and have proved abnormal in several autoimmune or immunodeficiency disorders. The number of TG lymphocytes in the patients did not differ from that in normal controls. It is possible that 1) suppressor T-lymphocytes are not involved in the pathogenesis of Hashimoto's disease or 2) antigen-specific suppressor T-cells are involved, but too are low in number with respect to total TG.

Abstract
Somatomedin was measured by rat bioassay in samples obtained from renal artery and vein, in order to study the role of this organ in the production of somatomedin activity. The results showed a significant difference, with an increase of the activity in the venous samples. According to the data reported in the literature with bioassay (low values) and radioreceptor assay (normal or high values) in nephropathic subjects, our results seem to suggest that the kidney mainly inactivates a specific somatomedin inhibitor.
