Role of hormonal risk factors in HER2-positive breast carcinomas

Examination of parity, age at menarche and at menopause by HER2 status in a large series of breast carcinomas showed a statistically significant increased-frequency of HER2-positive tumours in lower risk subgroups. The findings suggest a difference in the protective role of hormone-related risk factors between HER2-positive and -negative tumour

ENAMA “Certification” of the inspection workshop activity: the necessary requirements

In European Directive 128/2009/EC it is stated that “each Member State shall establish certificate systems designed to allow the verification of sprayers inspections”, but no further indications are provided on how to make such certifications. In Italy the ENAMA (National Board for Agricultural Mechanization) working group – established to co-ordinate the sprayers inspection activities at national level – has prepared a specific document containing the guidelines on how to get, on a voluntary basis, an ENAMA certification which attests the conformity of test equipment and of test procedures adopted in the inspection workshops. In this document directions are reported on how to assess the conformity of the inspection workshops to a set of listed requirements, referred either to other ENAMA documents, or to the National Action Plan, or to ISO/IEC 17020.The ENAMA certification of conformity therefore represents an added value for the sprayers inspection and calibrations Workshops as it ensures, through periodical inspections, that workshops apply the correct administrative (e.g. management of data and record of test reports) and technical procedures in their inspection activity and that they use appropriate test equipment and instruments. In this paper the requirements needed to get and to maintain over time the ENAMA certification of conformity are described

The necessity of a harmonized procedure for sprayers inspectors training: the Italian activity

European Directive on Sustainable Use of Pesticides requires that the people making inspections of sprayers in use have an official license, recognized at national level, released by the competent Authority. In Italy, Authorities responsible of training and upgrading of sprayers inspectors are Regional and Provincial administrations. They make this job in collaboration with research institutes that provide qualified teachers.With the aim to homogenize in the whole country the activity of training and licensing of sprayers inspectors the rules for training courses and the criteria for releasing licenses have been defined by ENAMA. Training courses shall have a duration of at least 40 hours subdivided between theory (60% of total time) and practical (40% of total time).Topics treated during courses are: criteria to apply pesticides, main sprayer types used in agriculture and relative components, test methods and equipment used to carry out the inspections of sprayers in use and to adjust them. The exam to get the inspector license shall consist in: a) filling of a questionnaire with multiple answers (at least 80% of answers have to be correct); the questions are selected among a database approved by ENAMA Working Group; b) oral test; c) practical exam consisting in the complete inspection of one sprayer.In order to guarantee the same quality level of sprayers inspections in the different European countries and to guarantee the mutual recognition of inspections made it is considered necessary to reach in short terms an agreement to harmonize the activity of training, licensing and upgrading of sprayers inspectors across Europe

A proposal for an EU (SPISE) database of the licensed sprayers inspectors and inspection centres

In order to guarantee at European level the easy identification of sprayers inspected and to allow mutual recognition of inspections as recommended by the European Directive on Sustainable Use of Pesticides (128/2009/EC) it would be necessary to create a SPISE database enabling to collect the list of the technicians authorized to make inspections of sprayers in use and of the licensed inspection centers. This database should be managed at SPISE level and should be linked to the national databases for getting regular updates.Actually in Italy there is a public national online database (www.centriprovairroratrici.unito.it) that was realized by the ENAMA working group. Only the sprayers inspected by the test stations listed in this database are recognized all over the country.This national database contains also the results of all the inspections made in the different Italian Regions and therefore provides a support for monitoring the inspection activity at national level. Independently of the software used at local level for managing data of sprayer inspections, some key information have to be necessarily provided in order to identify the sprayer inspected.They are the coordinates of the test station, the name of the technician who inspected the sprayer, the name of the owner of the sprayer, the data of the machine inspected, the date of the inspection and its response

Topical administration of a doxorubicin-specific monoclonal antibody prevents drug-induced mouth apoptosis in mice

One of the most severe side effects of anti-tumour chemotherapy is mucositis due to drug toxicity for rapidly dividing cells. We show here that anti-DXR monoclonal antibodies can prevent DXR-induced damage. Indeed, apoptosis, confined to the proliferative compartment of the basal mucosa, observed in the tongue of DXR-treated mice was completely inhibited by topical application of the anti-DXR antibodies. © 2001 Cancer Research Campaign http://www.bjcancer.co

The lung microbiota: role in maintaining pulmonary immune homeostasis and its implications in cancer development and therapy

Like other body districts, lungs present a complex bacteria community. An emerging function of lung microbiota is to promote and maintain a state of immune tolerance, to prevent uncontrolled and not desirable inflammatory response caused by inhalation of harmless environmental stimuli. This effect is mediated by a continuous dialog between commensal bacteria and immune cells resident in lungs, which express a repertoire of sensors able to detect microorganisms. The same receptors are also involved in the recognition of pathogens and in mounting a proper immune response. Due to its important role in preserving lung homeostasis, the lung microbiota can be also considered a mirror of lung health status. Indeed, several studies indicate that lung bacterial composition drastically changes during the occurrence of pulmonary pathologies, such as lung cancer, and the available data suggest that the modifications of lung microbiota can be part of the etiology of tumors in lungs and can influence their progression and response to therapy. These results provide the scientific rationale to analyze lung microbiota composition as biomarker for lung cancer and to consider lung microbiota a new potential target for therapeutic intervention to reprogram the antitumor immune microenvironment. In the present review, we discussed about the role of lung microbiota in lung physiology and summarized the most relevant data about the relationship between lung microbiota and cancer

TLR3 expression induces apoptosis in human non‐small‐cell lung cancer

The prognostic value of Toll\u2010like receptor 3 (TLR3) is debated in cancer, differing between tumor types, methods, and cell types. We recently showed for the first time that TLR3 expression on early stage non\u2010small\u2010cell lung cancer (NSCLC) results associated with a good prognosis. Here, we provide experimental evidences explaining the molecular reason behind TLR3\u2019s favorable prognostic role. We demonstrated that TLR3 activation in vitro induces apoptosis in lung cancer cell lines and, accordingly, that TLR3 expression is associated with caspase\u20103 activation in adenocarcinoma NSCLC specimens, both evaluated by immunohistochemistry. Moreover, we showed that TLR3 expression on cancer cells contributes to activate the CD103+ lung dendritic cell subset, that is specifically associated with processing of antigens derived from apoptotic cells and their presentation to CD8+ T lymphocytes. These findings point to the relevant role of TLR3 expression on lung cancer cells and support the use of TLR3 agonists in NSCLC patients to re\u2010activate local innate immune response
