Microvascular Techniques
No full textReconstructive microsurgery has become an integral part of head and neck reconstructive surgery, allowing the completion of complex resections with predictable outcome. These improvements are related to technological advances, better imaging, advances in surgical techniques, and new surgical instruments. With regard to microsurgery, research is nowadays focused on flap selection, design, and computer customization of the procedure. However, regardless of the innovation introduced, it is undoubtable that the actual clinical success in microsurgery relies on good technical skill in vessel anastomosis. Microsurgical anastomosis is based on simple sequential surgical maneuvers that are essential to strictly follow in order to guarantee the best outcome
CHIRURGIA IMPLANTO-PROTESICA POST-ONCOLOGICA: DALLA GESTIONE DELL’OSSO A QUELLA DEI TESSUTI MOLLI
No full textCombined modality staging of high risk rectal cancer
No full textThe personal experience with the radiologic staging of high risk rectal cancer undergoing preoperative treatment is reported. 61 patients shown to be affected by locally advanced (T3-T4, N+ with any T) rectal tumors on combined modality staging, underwent restaging 4-5 weeks after treatment. In all patients liver US, pelvic CT and colorectal enema were performed before and after treatment. In 22 patients with low rectal cancer transrectal sonography was performed. In 19 patients pelvic MRI was performed. The 61 patients were considered operable on second staging and thus referred to surgery. Subsequent control on histology has confirmed the diagnostic accuracy of the single procedures and of their combination. US was shown to be of high accuracy in the evaluation of T (90.8%) and of high predictive value for N. CT accuracy (84%) and MRI accuracy (78.9%) was lower because both tend to overstaging in the evaluation of T of rectal tumors undergoing preoperative treatment. Low CT accuracy (64%) and MRI accuracy (58%) was observed for N. There was optimum agreement between histology and imaging in the assessment of tumor shrinkage, well visualized by rectal enema which supported combined restaging with 88% accuracy for T
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Confined Functionalization of Mesoporous Silicon Layers
No full textThe unique ability of porous silicon PS formation-functionalization method to confine organic molecules in a selected layer of a PS stack was demonstrated in this paper. Two different experiments were carried out to prove the confinement of 1-heptyne in a selected layer of a PS stack. The organic molecule was added to the anodizing solution during the formation of the functionalized layer only, and its covalent bonding to the PS surface was assessed by Fourier transform infrared spectroscopy and energy dispersive X-ray spectroscopy. At first, a stack with an extremely thin sacrificial layer was prepared in order to separate by brittle fracture the functionalized layer from the unfunctionalized one. Further evidences of spatially selective functionalization were obtained by studying a three-layer sample with the organic molecule confined in the central layer. This will allow developing new applications such as PS multichannel sensors and lab-on-chip systems based on PS
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
