Abstract
Brain derived neurotrophic factor (BDNF) regulates several CNS physiological and pathological processes. To investigate in multiple sclerosis (MS) patients, the relationship between the Val66Met polymorphism of BDNF and clinical markers of disease activity and MRI markers of focal and diffuse brain pathologies. 45 MS patients and 34 healthy controls (HCs) were genotyped and subjected to clinical-MRI examination. Global white matter fraction (gWM-f), gray matter-f (GM-f), cerebrospinal fluid-f (CSF-f), and abnormal WM-f were measured. We studied 26 Val/Val and 19 Val/Met patients and 23 Val/Val and 11 Val/Met HCs. We found that Val/Val patients had lower GM-f and higher CSF-f than Val/Val HCs; such differences were not statistically significant comparing Val/Met patients to HCs. The regression analysis showed that both Val/Met genotype and relapse number were associated with lower CSF-f. Our data suggest that Met allele might be a protective factor against MS as it is associated to a lower brain atrophy.

Abstract
Giant-cell arteritis (GCA) is a chronic vasculitis of the elderly usually involving the ophthalmic arteries, which can result in visual loss. High platelet counts may have some pathogenic significance in the obstruction of the ophthalmic circulation and a few cases of associated essential thrombocythaemia and GCA have been described. Here we report a case of severe temporal arteritis associated with essential thrombocythaemia.

Abstract
BACKGROUND Non-steroidal anti-inflammatory drugs (NSAIDs) can cause serious gastrointestinal side effects. Faecal calprotectin assay represents a simple and practical method for diagnosis of NSAID enteropathy. Intestinal micro-organisms are necessary for the development of NSAID-induced small bowel lesions and hence it has been suggested that probiotics could protect against NSAID enteropathy. AIM To evaluate the effect of a probiotic mixture in comparison with placebo on faecal calprotectin concentrations (FCCs) in healthy volunteers receiving indomethacin. METHODS In a double-blind, cross-over trial, 20 healthy volunteers ingested a daily dose of probiotic mixture (VSL#3) or placebo for 21 days. From day 16 to day 19, all subjects were also administered 50 mg/day of indomethacin. FCCs were measured the day before starting probiotic/placebo ingestion (T0), and every day from day 15 to day 21. RESULTS During dosing with probiotic, median FCCs were significantly increased only at day 17 with respect to T0 values, whereas during dosing with placebo, they were significantly increased at every day from day 17 to day 21 with respect to T0 values. CONCLUSIONS Treatment with VSL#3 before and during indomethacin therapy significantly reduces FCCs in healthy subjects with respect to placebo, suggesting that this approach could be useful in decreasing indomethacin-induced intestinal inflammation.

Abstract
The electron-positron collider DAPhiNE, the Italian Phi factory, has been recently upgraded in order to implement an innovative collision scheme based on large crossing angle, small beam sizes at the crossing point, and compensation of beam-beam interaction by means of sextupole pairs creating a "crab-waist" configuration in the interaction region. Experimental tests of the novel scheme exhibited an increase by a factor of 3 in the peak luminosity of the collider with respect to the performances reached before the upgrade. In this Letter we present the new collision scheme, discuss its advantages, describe the hardware modifications realized for the upgrade, and report the results of the experimental tests carried out during commissioning of the machine in the new configuration and standard operation for the users.

Abstract
In this Letter we report the first experiments aimed at the simultaneous demonstration of the emittance compensation process and velocity bunching in a high brightness electron source, the SPARC photoinjector in INFN-LNF. While a maximum compression ratio up to a factor 14 has been observed, in a particular case of interest a compression factor of 3, yielding a slice current of 120 A with less than 2 microm slice emittance, has been measured. This technique may be crucial in achieving high brightness beams in photoinjectors aiming at optimized performance of short wavelength single-pass free electron lasers or other advanced applications in laser-plasma accelerators.

Abstract
The extraction efficiency of aflatoxin B1 (AFB1) in cattle feed containing nine adsorbents (ADSs) was investigated using two organic/aqueous solvents composed of methanol/water (80/20 v/v; MeOH) and acetone/water (85/15 v/v; AC). Samples were obtained including a highly AFB1-contaminated (HC) and a low-level AFB(1)-contaminated (LC) feedstuff (15.33 and 7.57 microg kg(-1), respectively), nine ADSs (four clay minerals; one yeast cell wall-based product; one activated carbon and three commercial ADS products) at two different levels of inclusion (10 and 20 g kg(-1)). After solvent extraction and immunoaffinity column clean-up, all samples were analysed for AFB1 by high-performance liquid chromatography (HPLC) with fluorescence detection. For each contamination level (HC and LC), the data obtained were analysed using a factorial arrangement in a completely randomized design. Means were compared with the correspondent controls using the Dunnett's test. No statistical difference was found in AFB1 levels of feedstuffs not containing ADSs when extracted with AC or MeOH, even if numerically higher values were obtained with AC. A dose-dependent effect (p < 0.01) of ADSs inclusion was observed on AFB1 recoveries that were lower when the higher ADS level (20 g kg(-1)) was included in the HC and LC feedstuffs. Higher AFB(1) recoveries were obtained using AC compared with MeOH, both in HC (75.0% versus 12.0%, respectively) and in LC (84.0% versus 22.8%, respectively) ADSs containing feedstuffs. However, when the activated carbon and the sodium bentonite were included in feeds, lower AFB1 concentrations with respect to control values (p < 0.001 and <0.05, respectively) were obtained also using AC. The data obtained in this study indicate that routine use of the MeOH solvent for AFB1 analysis of unknown feedstuffs, can produce misleading results if they contain an ADS.

Abstract
"Functional dyspepsia" represents a clinical condition of pain and/or persistent or recurrent discomfort that concerns a large portion of the healthy population. It has already been shown that some herbs (Melissa Officinalis, Cynara scolymus) can have favorable effects on digestion. The principal aim of this study is to determine whether the ingestion of "Gran Soleil" dessert, with or without herbs, after meals can be beneficial to health in subjects suffering from functional dyspepsia. For this purpose, thirty subjects with functional dyspepsia were enrolled and were asked to consume "Gran Soleil" with or without herbs; these subjects reported the course of their symptoms on VAS scale, during the basal period and after the ingestion "Gran Soleil" with and without herbs. It has been shown that the ingestion of "Gran Soleil" without herbs can induce a reduction both in the number of events connected to a dyspeptic syndrome and in their intensity; moreover the assumption of "Gran Soleil" with the addition of herbs helped to intensify this effect.

Abstract
Specific antibodies are essential tools for studying proteins as well as for diagnostic research in biomedicine. The egg yolk of immunized chicken is an inexpensive source of high-quality polyclonal antibodies. The 12-kDa Parietaria judaica 2 allergen was expressed as a fusion protein and was used to immunize Leghorn chickens. In this paper, we show, using 2-dimensional gel electrophoresis and immunoblotting, that chicken antibodies raised against a recombinant allergen can be used to recognize similar proteins from a pollen raw extract. Allergen identity was confirmed by nanoLC-nanospray-tandem mass spectrometry analysis. Our data demonstrate for the first time that a synergistic combination of molecular biology, 2-dimensional PAGE, and use of nonmammalian antibodies represents a powerful tool for reliable identification of allergens.

Abstract
It is well-known that digestion has a pivotal role in maintaining a state of wellbeing. The influence of certain foods and some herbal drugs has been ascertained. Epidemiological data show that the Mediterranean diet, with a high consumption of fresh vegetables and fruit, mainly citrus, has a beneficial effect and plays a protective gastrointestinal role. Previously, we assessed the influence on the eventual occurrence of symptoms during digestion of an iced dessert containing a mixture of digestive plant extracts, citrus juices and liquors, showing that its ingestion does not cause significant gastrointestinal symptoms in healthy volunteers. Taking into consideration that sensory properties of food may also influence digestion, we also evaluated the palatability of the product. In order to evaluate the effect of different tastes on the digestive processes, we performed a further similar evaluation with two new flavours. The ingestion of these iced desserts at the end of the meal does not cause significant gastrointestinal symptoms. Moreover, palatability median score shows a good appreciation of the products. Therefore, the combination of digestive herbs, citrus juice and liquors in different flavours gives rise to a product with a positive mix of good palatability, favourable acceptance and herbal constituents, able to maintain a good digestive condition.

Abstract
Esthesioneuroblastoma is an uncommon tumour. Due to its low incidence, this neoplasm is difficult to evaluate and its treatment remains a matter of debate. Although the role of post-operative radiation is relatively well-defined, little is reported regarding the role of radiotherapy as the only treatment modality. A retrospective analysis of the literature has been conducted. With reference to the treatment of esthesioneuroblastoma, 55 patients submitted only to radiotherapy have been selected from publications of internationally indexed literature between 1979 and 2006. According to the Kadish classification, 6 patients were in stage A, 12 in stage B, and 37 in stage C. Response to therapy for each stage was assessed. There was no evidence of disease in: 6/6 stage A patients with a median follow-up period of 103.6 months, 7/12 stage B patients with a median followup period of 120 months, and 7/37 stage C patients with a median follow-up period of 77.3 months. A total of 27 patients died due to tumour-related causes and 5 due to intercurrent disease, while 3 patients were alive with disease (local recurrence and cervical lymph node metastasis). In conclusion, esthesioneuroblastoma is a malignant tumour which grows both locoregionally and distantly. For this reason, despite the satisfying results regarding response to radiotherapy alone in stage A patients, irradiation should be used only in early lesions arising below the cribriform plate, whereas all other cases require aggressive and multimodal therapy.

Abstract
BACKGROUND Despite the reported tolerance to a low dose of lactose, many lactose malabsorbers follow a rigorous lactose-free diet also avoiding lactose-containing drugs. Up to now, only a few case reports have described the onset of gastrointestinal symptoms in lactose malabsorbers following the ingestion of these drugs. It has been suggested that capsules/tablets contain no more than 400 mg of lactose. AIM To evaluate breath H(2) excretion and intolerance symptoms after ingestion of a capsule containing 400 mg of lactose or placebo through a randomized, cross-over, double-blind, controlled study. METHODS Seventy-seven lactose maldigesters with intolerance underwent two H2 breath tests with both 400 mg of lactose and 400 mg of placebo. Gastrointestinal symptoms occurring in the 8 h following the ingestion of different substrates were evaluated by a visual-analogue scale. RESULTS Ingestion of 400 mg of lactose did not cause a significant difference in breath H2 excretion or in the severity of gastrointestinal symptoms compared to placebo. CONCLUSION In patients with lactase deficiency, drugs containing 400 mg of lactose or less can be used safely.

Abstract
The gastrin-releasing peptide receptor (GRPR) was implicated for the first time in the pathogenesis of Autism spectrum disorders (ASD) by Ishikawa-Brush et al. [Ishikawa-Brush et al. (1997): Hum Mol Genet 6: 1241-1250]. Since this original observation, only one association study [Marui et al. (2004): Brain Dev 26: 5-7] has further investigated, though unsuccessfully, the involvement of the GRPR gene in ASD. With the aim of contributing further information to this topic we have sequenced the entire coding region and the intron/exon junctions of the GRPR gene in 149 Italian autistic patients. The results of this study led to the identification of four novel point mutations, two of which, that is, C6S and L181F, involve amino acid changes identified in two patients with ASD and Rett syndrome, respectively. Both the leucine at position 181 and the cysteine at position 6 are strongly conserved in vertebrates. C6S and L181F mutant proteins were expressed in COS-7 and BALB/3T3 cells, but they did not affect either GRP's binding affinity or its potency for stimulating phospholipase C-mediated production of inositol 1,4,5-trisphosphate. In summary, our results do not provide support for a major role of the GRPR gene in ASD in the population of patients we have studied. However, there is a potential role of C6S and L181F mutations on GRPR function, and possibly in the pathogenesis of the autistic disorders in the two patients.

Abstract
A good digestion is essential to maintain a healthy status. It is known that physiological digestive processes could be improved by the ingestion of some medicinal plants, while specific foods can facilitate the occurrence of gastrointestinal symptoms. Moreover, sensory properties of food seem to also influence digestion. We assessed the influence on physiological digestive processes of two Gran Soleil (GS) products containing a mixture of digestive plant extracts, citrus juices and liquors. We evaluated, in 10 healthy volunteers, the eventual occurrence of gastrointestinal symptoms after their ingestion and measured their palatability. Ingestion of GS did not cause significant gastrointestinal symptoms. Moreover, the palatability median score shows a good appreciation of the products. In conclusion, it is possible to suppose that a product with a good palatability, able to support and maintain a good digestive condition, derives from the mixture of digestive herbs, citrus juices, liquor and other ingredients.

Abstract
In this Letter we report the first experimental observation of the double emittance minimum effect in the beam dynamics of high-brightness electron beam generation by photoinjectors; this effect, as predicted by the theory, is crucial in achieving minimum emittance in photoinjectors aiming at producing electron beams for short wavelength single-pass free electron lasers. The experiment described in this Letter was performed at the SPARC photoinjector site, during the first stage of commissioning of the SPARC project. The experiment was made possible by a newly conceived device, called an emittance meter, which allows a detailed and unprecedented study of the emittance compensation process as the beam propagates along the beam pipe.

Abstract
PURPOSE Our study aimed to assess the role of magnetic resonance imaging (MRI) in the characterisation of musculoskeletal tumours and to identify specific perfusion patterns for the different tumours. MATERIALS AND METHODS Between January 2003 and September 2005, we evaluated the conventional and perfusion MRIs of 39 patients with musculoskeletal tumours. Dynamic MRI was performed with a 1.5-T and 1.0-T MRI unit before and after the intravenous administration of contrast material, using dedicated phased-array coils appropriate for the region to be studied and fast and ultrafast consecutive sequences. Postprocessing was done on an independent workstation (Advantage Windows, GE Medical System), with Functool (GE) software, which allowed a quantitative evaluation of enhancement as a function of time. The results were compared with the histopathological diagnoses obtained by biopsy or surgery. RESULTS The lesions identified in the 39 patients included 23 soft tissue tumours (12 benign, 11 malignant) and 16 bone tumours (ten benign, six malignant). Comparing the time-intensity diagrams of lesions of the same histological type, we found typical enhancement patterns for some bone tumours only, especially for bone, cartilaginous, fibrohistiocytic and pseudoinflammatory lesions. No typical enhancement pattern could be detected for any of the histological types of soft tissue tumour. Analysis of the slope of the time-intensity curves has a sensitivity and specificity of 64%-58% for soft tissue tumours and 86%-67% for bone tumours in determining the biological aggressiveness of the lesions. CONCLUSIONS Perfusion MRI had moderate sensitivity and specificity in the differential diagnosis between lesions with high or low biological activity. Only in a few cases was it possible to find some correlation between perfusion patterns and lesion histology. The slope values should therefore be used in combination with conventional spin-echo images and other imaging and clinical data in order to narrow the field of the possible differential diagnoses and reliably predict the nature of the lesion.

Abstract
We report the case of a 36-year-old Senegalese male with non-scarring alopecia of the scalp, including nodules and pustules, diagnosed as tinea capitis caused by Trichophyton soudanense. This dermatophyte is endemic in Central Africa and is becoming more frequent in Europe because of immigration. It has seldom been isolated in Italy. Tinea capitis is common in childhood and it is rare in adults, in which female sex is preferred. In adults, alopecic patches have to be distinguished from those due to other dermatoses inducing alopecia.
