Roadmap on holography
From its inception holography has proven an extremely productive and attractive area of research. While specific technical applications give rise to 'hot topics', and three-dimensional (3D) visualisation comes in and out of fashion, the core principals involved continue to lead to exciting innovations in a wide range of areas. We humbly submit that it is impossible, in any journal document of this type, to fully reflect current and potential activity; however, our valiant contributors have produced a series of documents that go no small way to neatly capture progress across a wide range of core activities. As editors we have attempted to spread our net wide in order to illustrate the breadth of international activity. In relation to this we believe we have been at least partially successful.This work was supported by Ministerio de Economía, Industria y Competitividad (Spain) under projects FIS2017-82919-R (MINECO/AEI/FEDER, UE) and FIS2015-66570-P (MINECO/FEDER), and by Generalitat Valenciana (Spain) under project PROMETEO II/2015/015
Schirrous invasive ductal carcinoma of the breast overexpress p53 oncoprotein
CONTEXT: Breast cancer is the most important neoplasm in adult women, and its worldwide incidence is growing. The tumoral stroma is very important for modulating the growth and invasion of the tumor itself. The relationship between these two components is not completely understood. Schirrous carcinoma is a variant of ductal invasive carcinoma in which the stroma is very desmoplastic, and the importance of this finding still a motive for debate in the literature. OBJECTIVE: To compare the desmoplastic reactions against biological markers, such as estrogen and progesterone receptors, oncoprotein c-erbB-2 and oncoprotein p53, with the objective of studying the relationship between the tumoral stroma and epithelial cancer cells. TYPE OF STUDY: Retrospective study. SETTING: Cancer Hospital A C Camargo and Faculty of Medicine of Ribeirão Preto, University of São Paulo, São Paulo, Brazil. SAMPLE: 107 adult women operated because of ductal invasive carcinoma. The cases were separated into 4 groups according to the desmoplastic reaction -- less than 15%, between 15-50%, 51-85%, and more than 85% fibrosis. The grade of fibrosis was determined by picrus-sirius staining and quantified by using a microscope with a stereo-imaging grid. Immunohistochemical methods were used to determine the expression of the hormonal receptors and c-erbB-2/p53 oncoprotein. MAIN MEASUREMENTS: Extent of desmoplastic reaction versus expression of estrogen and progesterone receptors, oncoprotein c-erbB-2, and oncoprotein p53. RESULTS: The results showed that schirrous carcinoma expresses oncoprotein p53 more frequently than other carcinomas with less extensive desmoplastic reaction. There were no differences between the grade of fibrosis and the other biological markers. CONCLUSION: The intense stromatous reaction in invasive ductal carcinoma may modulate the expression of p53. Further investigations should be made with the aim of understanding how this expression determines the proliferative activity in schirrous carcinoma, and whether this overexpression is secondary to mutation of the p53 gene or due to modulation of other molecules of the stroma
Return to Sport at Preinjury Level is Common After Surgical Treatment of SLAP Lesions: A Systematic Review and a Meta-analysis.
Patients undergoing surgery for Superior-Labrum-anterior-to-posterior (SLAP) lesions are often worried about their return to sport performance. This systematic review determined the rate of return to sport and return to sport at the previous level (RTSP) after surgery for SLAP lesion. The PRISMA guidelines were followed. Meta-analysis of data through forest plot projections was conducted. Studies were divided and analyzed according to the type of interventions (isolated slap repair or SLAP repair with rotator cuff debridement and biceps tenodesis). The mean overall rate of return to sport after the procedures was 90.6% and the mean overall rate of return to sport at the previous level after the procedures was 71.7%. RTSP rates of the whole population were 71% (95% CI: 60%-80%), 66% (95% CI: 49%-79%), and 78% (95% CI: 67%-87%) for isolated SLAP repair, SLAP repair with the rotator cuff debridement and biceps tenodesis, respectively. A lack of subgroup analysis for the specific performance demand or type of lesion related to the surgical technique used might induce a high risk of bias. Return to sports at the previous level after surgically treated superior labrum anterior to posterior lesion is possible and highly frequent, with the highest rates of RTSP in patients treated with biceps tenodesis. More studies and better-designed trials are needed to enrich the evidence on indications of SLAP surgical treatment in relation to specific sports-level demand. Level-IV.

A multi-DNA preventive vaccine for p53/Neu driven cancer syndrome.
The highly aggressive cancer syndrome of female mice carrying a p53 knockout allele and a rat HER-2/neu (Neu) transgene (BALB-p53Neu) can be prevented by a cell vaccine presenting three components: Neu, interleukin (IL)-12 production, and allogeneic major histocompatibility complex (MHC) alleles (Triplex cell vaccine). Here we tested a second-generation Triplex DNA-based vaccine (Tri-DNA), consisting of the combination of three gene components (a transmembrane -extracellular domain fragment of the Neu gene, IL-12 genes, and the H-2D(q) allogeneic MHC gene), carried by separate plasmids. The Tri-DNA vaccine was at least as effective as the Triplex cell vaccine for cancer immunoprevention, giving a similar delay in the onset of mammary cancer and complete protection from salivary cancer. Both vaccines induced anti-Neu antibodies of the murine IgG2a isotype at similar levels. The Tri-DNA vaccine gave more restricted immunostimulation, consisting of a fully helper T cell type 1 (Th1)-polarized response, with effective production of interferon (IFN)-gamma in response to the vaccine but no spontaneous production, and no induction of anti-Neu IgG3 antibodies. On the other hand, the Triplex cell vaccine induced both Th1 and Th2 cytokines, a strong increase in spontaneous IFN-gamma production, and high levels of IgG3 antibodies recognizing Neu-positive syngeneic cells. In conclusion, the Tri-DNA vaccine is as effective as Triplex cell vaccine, exploiting a more restricted immune stimulation

A study of film and foil materials for the GEM detector proposed for the CMS muon system upgrade
During the next shutdown of the LHC at CERN, the CMS experiment plans to start installing GEM detectors in the endcap (high pseudorapidity) region. These muon detectors have excellent spatial and temporal resolution as well as a high chemical stability and radiation hardness. A report is given on preliminary results of materials studies that aimed to fully characterize the GEM detector components before and after the exposure to a high-radiation environment. © CERN 2014 for the benefit of the CMS collaboration..SCOPUS: ar.jinfo:eu-repo/semantics/publishe
Raccomandazioni cliniche in odontostomatologia
L’Organizzazione Mondiale della Sanità considera la salute orale come parte integrante, non solo
dello stato di salute generale, ma anche della qualità della vita di ciascun individuo.
In tale ottica, in accordo e con il sostegno del mondo professionale e della comunità scientifica di
questo settore, le raccomandazioni cliniche in odontostomatologia contenute nel presente volume
forniscono indicazioni e definiscono standard di intervento per la prevenzione e la cura delle più
comuni patologie del cavo orale nonché per l’identificazione di percorsi terapeutici appropriati a
supporto degli operatori pubblici e privati.
Esse costituiscono, inoltre, uno strumento utile per mantenere alto il livello di qualità delle cure in
questo periodo storico, nel quale, se da un lato crescono le opportunità tecniche di cura e la
potenziale domanda delle stesse, dall’altro la riduzione delle risorse economiche a disposizione dei
cittadini tende a limitare l’accesso all’offerta professionale privata e, al contempo, i processi di
razionalizzazione dell’allocazione dei fondi nel SSN rendono più difficile l’accesso alle strutture
pubbliche.
L’individuazione di raccomandazioni cliniche chiaramente definite e rese pubbliche può facilitare la
condivisione degli obiettivi e dei percorsi terapeutici tra odontoiatra e paziente, migliorare la
comunicazione e, in ultima analisi, accrescere la fiducia sia nei riguardi del proprio specifico
professionista che del “sistema delle cure” più in generale.
La revisione delle “Raccomandazioni cliniche in odontostomatologia” si è resa necessaria in
considerazione del cambiamento dell’evidenza scientifica, dell’immissione in commercio di nuovi
materiali e dell’utilizzo di nuove tecnologie, specie in ambito protesico.
Come per la precedente, alla realizzazione di questa edizione ha contribuito un ampio gruppo di
docenti ed esperti delle singole branche odontoiatriche insieme alle più importanti e rappresentative
Associazioni professionali e ai componenti della Commissione Albo Odontoiatri (CAO) nazionale
