Cost-Effective Organization of an Institutional Human Cancer Biobank in a Clinical Setting: CRO-Biobank Experience Toward Harmonization
This report describes the organization of the Biobank of the CRO Aviano National Cancer Institute, Aviano (CRO-Biobank), Italy, implemented as a structured facility dedicated to collecting human biological samples. It describes a particular disease-specific biobank and the integration of a research biobank in a clinical setting. The CRO-Biobank's mission is rooted in supporting and implementing cancer research, with its main focus on optimizing technical and quality processes, while also investigating ethical, legal and IT topics.The CRO-Biobank has implemented processes aimed at guaranteeing the safety of the providers, protecting patient privacy and ensuring both the traceability and quality of its samples. Our 8 years of experience allow us to offer insights and useful suggestions that may solve theoretical and practical issues that can arise when starting up new biobanks or developing existing biobanks further
Atypical Bilateral Femur Fractures in a Long-Term Bisphosphonate Therapy: A Case Report
Atypical Femur Fractures (AFF) are associated with Bisphosphonate Osteoporosis Therapy. Bisphosphonate therapy is widely used as the Gold-Standard Therapy for Osteoporosis: it increases bone density and reduce the risk of vertebral, non-vertebral and hip fractures. However, long-term alendronic acid administration can causes severely suppressed bone turnover and finally non-traumatic stress fractures. Here we present a case of Non-Traumatic stress

Drafting Biological Material Transfer Agreement: A Ready-To-Sign Model for Biobanks and Biorepositories
Purpose: Due to the scarcity of publications, guidelines, and harmonization among national regulations, biobanks and institutions face practical and theoretical issues when drafting a material transfer agreement (MTA), the fundamental tool to regulate the successful exchange of biosamples and information. Frequently researchers do not execute MTAs because of a general lack of knowledge about this topic. It is thus critical to develop new models to prevent loss of traceability and opportunities both for researchers and biobanks, their exposure to various risks, and delays in transferring biomaterials.Methods: Through the involvement of institutional groups and professionals with multidisciplinary expertise, we have drawn up a ready-to-sign MTA for the CRO-Biobank (the biobank of the National Cancer Institute, CRO, Aviano), a standardized template that can be employed as a ready-to-use model agreement.Results: The team identified the essential components to be included in the MTA, which comprise i) permissions, liability and representations; ii) custodianship and distribution limitations; iii) appropriate use of materials, including biosafety concerns; iv) confidentiality, non-disclosure, and publications; v) intellectual property protection for both the provider and recipient.Conclusions: This paper aims to be an unabridged report (among the few works in the existing literature) providing a description of the whole process related to the formation of an MTA. Biobanks and institutions may consider adopting our ready-to-sign form as a standard model. The article discusses the most important issues tackled during the drafting of the document, thus proposing an operative approach for other institutions that face the same problems
Circulating anti-Hsp70 levels in nascent metabolic syndrome: the Casale Monferrato Study.
The metabolic syndrome (MetS) confers an increased risk of both type 2 diabetes and cardiovascular diseases (CVD). Heat shock protein 70 (Hsp70), an intracellular polypeptide, can be exposed on the plasma membrane and/or released into the circulation, eliciting both native and immune responses that may contribute to vascular damage. Our aim was to assess if serum anti-Hsp70 antibody levels were cross-sectionally associated with uncomplicated MetS. A cross-sectional case–control study from the nondiabetic cohort of the Casale Monferrato Study was performed. Subjects with established CVD and/or abnormal renal function were excluded. Case subjects (n = 180) were defined as those fulfilling the criteria for the diagnosis of MetS. Control subjects (n = 136) were completely free of any component of the MetS. Serum anti-Hsp70 levels were measured by immunoenzymatic assay. We found that anti-Hsp70 antibody levels were significantly higher in cases than in control subjects [122.6 (89.5–155.6) vs 107.1 (77.3–152.4) μg/ml, p = 0.04], even after age and sex adjustment. In logistic regression analysis, higher levels of log-anti-Hsp70 conferred greater odds ratio (OR) for MetS, independently of age and sex. There was a statistically significant trend of ORs across quartiles of anti-Hsp70 and values greater than 108.0 μg/ml conferred a 77 % increased OR of MetS as compared with values in the lower quartiles. The strength of the association slightly decreased after further adjustment for apolipoprotein B, smoking, and albumin excretion rate. In conclusion, our results show that serum anti-Hsp70 antibody levels are independently associated with nascent MetS
Serum levels of heat shock protein 27 in patients with acute ischemic stroke
Expression of intracellular heat shock protein 27 (Hsp27) rises in the brain of animal models of cerebral ischemia and stroke. Hsp27 is also released into the circulation and the aim of the present study was to investigated if serum Hsp27 (sHsp27) levels are altered in patients with acute ischemic stroke. sHsp27 was measured in 15 patients with acute ischemic stroke and in 14 control subjects comparable for age, sex, and cardiovascular risk factors. In patients, measurements were performed at admission and 1, 2, and 30 days thereafter. At admission, mean sHsp27 values were threefold higher in patients than in controls. In patients, sHsp27 values dropped after 24 h, rose again at 48 h, and markedly declined at 30 days, indicating the presence of a temporal trend of sHsp27 values following acute ischemic stroke
Dissecting the effect of soil on plant phenology and berry transcriptional plasticity in two Italian grapevine varieties (Vitis vinifera L.)
Grapevine embodies a fascinating species as regards phenotypic plasticity and genotype-per-environment interactions. The terroir, namely the set of agri-environmental factors to which a variety is subjected, can influence the phenotype at the physiological, molecular, and biochemical level, representing an important phenomenon connected to the typicality of productions. We investigated the determinants of plasticity by conducting a field-experiment where all terroir variables, except soil, were kept as constant as possible. We isolated the effect of soils collected from different areas, on phenology, physiology, and transcriptional responses of skin and flesh of a red and a white variety of great economic value: Corvina and Glera. Molecular results, together with physio-phenological parameters, suggest a specific effect of soil on grapevine plastic response, highlighting a higher transcriptional plasticity of Glera in respect to Corvina and a marked response of skin compared to flesh. Using a novel statistical approach, we identified clusters of plastic genes subjected to the specific influence of soil. These findings could represent an issue of applicative value, posing the basis for targeted agricultural practices to enhance the desired characteristics for any soil/cultivar combination, to improve vineyards management for a better resource usage and to valorize vineyards uniqueness maximizing the terroir-effect
Update on Foregut Molecular Embryology and Role of Regenerative Medicine Therapies
Esophageal atresia (OA) represents one of the commonest and most severe developmental disorders of the foregut, the most proximal segment of the gastrointestinal (GI) tract (esophagus and stomach) in embryological terms. Of intrigue is the common origin from this foregut of two very diverse functional entities, the digestive and respiratory systems. OA appears to result from incomplete separation of the ventral and dorsal parts of the foregut during development, resulting in disruption of esophageal anatomy and frequent association with tracheo-oesophageal fistula. Not surprisingly, and likely inherent to OA, are associated abnormalities in components of the enteric neuromusculature and ultimately loss of esophageal functional integrity. An appreciation of such developmental processes and associated defects has not only enhanced our understanding of the etiopathogenesis underlying such devastating defects but also highlighted the potential of novel corrective therapies. There has been considerable progress in the identification and propagation of neural crest stem cells from the GI tract itself or derived from pluripotent cells. Such cells have been successfully transplanted into models of enteric neuropathy confirming their ability to functionally integrate and replenish missing or defective enteric nerves. Combinatorial approaches in tissue engineering hold significant promise for the generation of organ-specific scaffolds such as the esophagus with current initiatives directed toward their cellularization to facilitate optimal function. This chapter outlines the most current understanding of the molecular embryology underlying foregut development and OA, and also explores the promise of regenerative medicine
PROJETO EXPERIMENTAL, CAMPANHA PUBLICITÁRIA “COLETIVO SINDICAL”
Este projeto visa o desenvolvimento de uma campanha publicitária para o Coletivo Sindical, a fim de melhorar a comunicação do mesmo, ou seja, solucionar a comunicação interna proferida pelos quinze sindicatos que compõem o Coletivo Sindical. O Coletivo Sindical é uma associação que tem como objetivo trabalhar em prol dos interesses sociais, profissionais, econômicos de seus filiados, visando a melhoria salarial e as condições de trabalho de cada categoria profissional, ampliando a representatividade dos trabalhadores, padronizando ações conjuntas. O Coletivo abrange a região Meio-Oeste de Santa Catarina, sua formação ocorreu com o propósito de fortalecer o movimento sindical, a nível regional, e nacional. Por meio da pesquisa de mercado realizada, foi possível identificar os problemas comunicacionais a serem solucionados, bem como, organizar a identidade visual do Coletivo Sindical, pois o mesmo não possui material publicitário que instigue a participação dos filiados na contribuição sindical e suas ações. A partir desta observação, a campanha foi desenvolvida com o tema “Bússola”, no sentido em que o Coletivo Sindical orienta seus filiados a conquistar seus direitos. O planejamento de mídia e a produção deram sequência a temática, assim, a campanha desenvolvida atingiu seus objetivos
