Proctological surgery: use of a salsobromoiodic gel solution in the post-operative period.
No full textBackground. This study was aimed to demonstrate the advantages
and the effi cacy of a salsobromoiodic gel solution sponge to use in
coloproctology after surgery for the most frequent pathologies of anal
canal and of perineal region.
Materials and Methods. The Authors have tested the salsobromoiodic
gel solution (Fertomcidina U®) in a consecutive series of patients referred
to 5 coloproctological centers where they have been submitted to surgery
for pathologies of anal canal and of perineal region. A total of 30 patients,
15 with clinico-instrumental diagnosis of III- IV degree haemorrhoids
and 15 with diagnosis of chronic anal fi ssure entered in a clinical followup
after an out-patient setting or surgery for the respective pathologies.
The gel formulation is realized as a salsobromoiodic solution containing
salicylic acid and magnesium biphosphate making a strong bactericide
and fungicide action applicable on human skin for tissues reparation and
their riepithelization
Expansion and Light-Sheet Microscopy for Nanoscale 3D Imaging
No full textExpansion Microscopy (ExM) and Light-Sheet Fluorescence Microscopy (LSFM) are forefront imaging techniques that enable high-resolution visualization of biological specimens. ExM enhances nanoscale investigation using conventional fluorescence microscopes, while LSFM offers rapid, minimally invasive imaging over large volumes. This review explores the joint advancements of ExM and LSFM, focusing on the excellent performance of the integrated modality obtained from the combination of the two, which is refer to as ExLSFM. In doing so, the chemical processes required for ExM, the tailored optical setup of LSFM for examining expanded samples, and the adjustments in sample preparation for accurate data collection are emphasized. It is delve into various specimen types studied using this integrated method and assess its potential for future applications. The goal of this literature review is to enrich the comprehension of ExM and LSFM, encouraging their wider use and ongoing development, looking forward to the upcoming challenges, and anticipating innovations in these imaging techniques
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“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
