Foodstuffs treatment by ionization; Stato attuale del processo di ionizzazione delle sostanze alimentari. The microbiological recovery cimica by ionization has spurred this new technology and its applications in foodstuffs treatment are more and more taking interest all over the world. At present, over 40 countries provide clearances for the treatment of about 45 different types of foodstuffs cosmetii in over 20 of them the process is already industrially utilized for spices, poultry, shrimps and vegetables.

Industrial food ionization plants, utilizing EB-machines or radioisotopes, are at present about 50 world-wide, with a uniform distribution in advanced as well as developing countries.

These costs are competitive with alternative treatments, beyond the recovery of economic productivity reduction caused by foodborne diseases.

Directory of Open Access Journals Sweden. Eppure, i nomi sono perfettamente funzionali: Full Text Available Abstract A new and simplified method was used to investigate on the feeding habits of a Dormouse population of the Asiago Plateau, Venetian Prealps; it is based on the volume evaluation of plant and animal components of the stomach contents by stain proceedings and by the identification of the large-sized remains.

The population studied has more carnivorous habits than others cited in the literature, and presents an increasing percentage of animal food in stomach contents during: The diet variety is lower and the ground level predation hcimica than those reported for other populations. This anomalous trophic behaviour is probably a consequence of changed conditions of the biocenosis, originally based on Cosmdtici stands and now on artificial pure stands of Norway Spruce, which is not frequently utilized as food.

The adaptation to this particular diet is prompt prdootti general, and it must be related to social learning.

The olive oil extraction industry is responsible for the production of high quantities of vegetation waters, represented by the constitutive water of the olive fruit and by the water used during the process.

For that reason the disposal of the vegetation water is very difficult and needs a previous depollution. The organic matter o New Pathways for Alimentary Mucositis.

Full Text Available Alimentary mucositis is a major dose-limiting toxicity associated with anticancer treatment. It is responsible for reducing patient quality of life and represents a significant economic burden in oncology. The pathobiology of alimentary mucositis is extremely complex, and an increased understanding of mechanisms and pathway interactions is required to rationally design improved therapies.

This review describes the latest advances in defining mechanisms of alimentary mucositis pathobiology in the context of pathway activation. It focuses particularly on the recent genome-wide analyses of regimen-related mucosal injury and the identification of specific regulatory pathways implicated in mucositis development.

This review also discusses the currently known alimentary mucositis appumti factors and the development of novel treatments. Suggestions for future research directions have been raised. Full Text Available Bacterial resistance to antibiotics represents one of the most important factors of treatment failure for infectious diseases.

In Helicobacter pylori HP infection, this aspect is of dramatic importance when considering eradication therapy which according to the most recent consensus chimiva implies an association appuntii a proton pump inhibitor PPI and two antibiotics mainly nitromidazoles, macrolides and beta-lactames.

Beside the strong recommendation after treatment failure, in-vitro test of resistance of the mostly used antibiotics, has gained also an ddei importance over time due to the progressive increase of resistance observed with most used substances as, for example, macrolides.

Metronidazole MTR and Clarithromycin CLA are almost routinely tested in our laboratory in cultures from HPpositive gastric biopsies using the disk diffusion technique fig. A retrospective analysis of culture results from gastric biopsies taken during gastroscopy performed in the endoscopy unit of our hospital over the last quinquennial, allowed us to monitor the prevalence of HP resistance to MTR e CLA and to assess their possible relationship with age and gender. Furthermore we studied the impact of resistance on typer of eradication therapy as well as the onset of secondary resistance and the stability of CLA resistance.

We have therefore considered an overall number of HP-positive cultures. This result may probably be related to the use of MTR by ginecologist for pelvic infection. Astrofisica delle alte energie. L’insegnamento dell ‘astrofisica moderna richiede conoscenze di base di svariate discipline, oltre ad alcuni modelli fondamentali.

Sulphides balance in tanning leather district in Tuscany: The paper deals with an evaluation of hydrogen sulphide emissions from leather tanning industries and water purification plants in the leather district in Deo. The aim of the work is to correlate different sources emissions of the area with pollutant concentrations recorded by the monitoring network.

Global quantities of treated substances, different plants typologies and operating mode, have been considered, following the indications of the ARPAT’s archives. This analysis, updated togives interesting information about the trend of emissions and their weight on air quality: The trend of measured concentration of pollutant in air shows a clear improvement of air quality during last three years Lo scopo chimuca ‘indagine e’ quello di valutare la possibilita’ di correlare le emissioni delle diverse sorgenti della zona con i valori di concentrazione di inquinante al suolo rilevati dlla rete di monitoraggio.

La valutazione tiene conto delle quantita’ complessive di sostanze lavorate, delle diverse tipologie degli impianti e del loro stato di funzionamento, secondo quanto risulta dai dati appuntu nell’archivio dell ‘ARPAT Agenzia Regionale per la Protezione Ambientale della Toscana.

Synchronous fluorescence spectroscopy for studying extracellular organic substances of Ulva rigida C. Centro Comune di Ricerca; Targa, C. Experiments performed using Ulva rigida thalli and enriched culture solutions demonstrated that Ulva emits extra-cellular organic substances the complexity of which can be pfodotti by synchronous fluorescence spectroscopy.

It was found that synchronous peak intensities hA excitation at nmhB nm and hC nm varies in relation to the age of the thallus and the prodofti of the emitted substances by the alga. That occurs since hA, after a first increase, tends to diminish in correspondence to a progressive increase of the peaks hB and hC due to the emission of the more and more cos,etici fluorescent organic substances.

A semi-static system was used. Le fonti di esposizioni ai pesticidi sono diverse. Il clearence dell ‘ettacloro e’ rapido e completo, ed il principale prodotto di accumulo e’ il suo metabolita, l’epossido di ettacloro, che persiste nell’ambiente per un periodo di tempo molto piu’ lungo. I dati sulla tossicita’ di questo metabolita sono paragonabili a appuni dell ‘ettacloro. La sua tendenza ad accumularsi nel tessuto grasso puo’ produrre seri pericoli all’ambiente nel quale e’ notevolmente persistente WHO, In Argentina l’uso di ettacloro e’ stato limitato fin dal quasi esclusivamente al controllo di insetti terrestri e e.

Alimentarymetabolic and toxic osteopathies in adults. Skeletal changes in deficient or badly balanced nutrition alimentary osteopathies and osseous changes accompanying chronic desease of internal organs rei metabolic disorders chlmica osteopathies are discussed.

Basically, the classical generalised skeletal changes such as osteoporosis, osteomalacia, fibroosteoclacia and sklerosis of the bone can occur in their pure form or as a combination of two or more of these disorders.


Finally the exogenic toxic osteopathies are discussed, nowadays fluorosis being the most important. Other external factors may be drugs like methotrexate and antiepileptic medications.

The aim of this study was to assess the daily fluoride intake analyzing duplicate samples of food and beverages. An attempt was made to calculate the daily intake of fluoride from food and swallowed toothpaste. Methods Daily alimentary fluoride intake was measured in a group of 36 children with an average age of alpunti. This was repeated prodottu six months. Parents recorded their child’s diet over 24 hours and collected duplicated portions of food and beverages received by children during this period.

Pooled samples of food and beverages were weighed and solid food samples were homogenized. Fluoride was quantitatively extracted from solid food samples by a microdiffusion method using hexadecyldisiloxane and perchloric acid. The content of fluoride extracted from solid food samples, as well as fluoride in beverages, was measured potentiometrically by means of a fluoride ion selective electrode. Results Average daily fluoride intake at baseline was 0.

Six months later it was 0. When adding the values of unwanted fluoride intake from the toothpaste shown in the literature 0. Conclusions In the children studied, observed daily fluoride intake reached the ptodotti for safe fluoride intake.

When adding the potential fluoride intake from swallowed toothpaste, alimentary intake reached the optimum range for daily fluoride intake.

Video interview with Michael Dell. The Bulletin and the Video productions team had the opportunity to meet him. The video interview is transcribed for your convenience. What motivated you to come and visit CERN? I obviously heard about the dosmetici science and research has going on here, and DELL is very pleased to be a partner and providing a lot of the computers to analyse the data and I really wanted to see for myself in person, some of the great science that is going on here.

What is your view on prodotyi research in IT, and in general? I think if you look at the field of science in the last hundred years, we have been able to solve a lot of problems, but there are still lots of unsolved problems and unsolved mysteries.

And it is only through basic fundamental research that we will address these probl Radiologic findings of the anthrax: To evaluate the radiologic findings of alimentary anthrax.

The diagnosis was made by demonstration of Bacillus anthracis in smear and culture of the contaminated meat. We evaluated the clinical manifestations and the findings of thoracic, abdominal radiographs, cervical, abdominal ultrasonograms and abdominal CT scans. Out of the 19 patients with the alimentary infection, 9 had oropharyngeal form, 18 had abdominal form and 8 had combination of oropharyngeal and abdominal form. The patients had general symptoms and signs such as fever, chill, myalgia.

Clinical symptoms and signs were sore throat, throat injection, throat ulcer and patch in oropharyngeal form, and nausea, vomiting abdominal pain, diarrhea, and gross GI bleeding in abdominal form. In two patients, late complications occurred as intestinal obstruction due to ileal stricture with perforation, and inflammatory changes of pelvic cavity due to ileovesical fistula. Radiologic findings of alimentary anthrax are difficult in differentiation from those of other inflammatory bowel disease, but those radiologic findings with clinical manifestations may be helpful in diagnosis and evaluation of disease process in patients with alimentary anthrax.

Sixty cats with clinical symptoms indicative of gastroin-testinal lymphosarcoma were examined radiographically and ultrasonographically.
