CYTOTOXICITY OF PACLITAXEL IN COMBINATION WITH CISPLATIN AND A NEW Pt-MERCAPTOPYRIDINE COMPLEX
No full textIn vitro synergy has been reported for exposure to paclitaxel prior to cis-platin (cis-DDP), whereas the reverse sequence resulted in antagonism. There is no clear evidence for an intracellular origin of the schedule-dependent interaction, but several hypotheses have been proposed, such as effects at the level of DNA crosslinks, or binding to tubulin sites. The purpose of this study was to evaluate the cytotoxicity of these two drugs as single agents, in combination and in sequence, against a human colon adenocarcinoma cell line (LoVo). Moreover, we considered the new Pt-mercaptopyridine complex C/2, was like cis-platin in being able to alter DNA conformation. We have therefore studied the cytotoxic effects after single agent exposure, concomitant exposure (paclitaxel + cis-platin and paclitaxel + C/2) and sequential drugs exposure (paclitaxel-->cis-platin and cis-platin-->paclitaxel or paclitaxel-->C/2 and C/2-->paclitaxel). Our results demonstrate that the most cytotoxic effect is induced by paclitaxel and C/2 exposure both in the case of concomitant cell treatment and sequential exposure paclitaxel-->C/2

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
Differential diagnosis between usual interstitial pneumonia (UIP) and nonspecific interstitial pneumonia (NSIP) assessed by high-resolution computed tomography (HRCT)
No full textDifferential diagnosis between usual interstitial pneumonia (UIP) and nonspecific interstitial pneumonia (NSIP) assessed by high-resolution computed tomography (HRCT).

Sezione di Scienze Radiologiche, Dipartimento di Scienze Cliniche, Universita degli studi di Parma, Parma, Italy. PURPOSE: The aim of this study was to assess the accuracy of high-resolution CT in the differential diagnosis between UIP and NSIP, and the correlations with histological and functional findings. MATERIALS AND METHODS: Patients underwent thin-collimation spiral CT (1 mm), with 10-mm interval. Pulmonary function was assessed with a pneumotacograph and body plethysmograph connected with a computer for data analysis. Three pathologists, blinded to the clinical and functional data, provided a histological diagnosis based on established criteria reported in the literature. The study group only included patients with a histological diagnosis of either UIP or NSIP. RESULTS: We achieved a correct diagnosis of NSIP in 86.6% of cases (76.4% sensitivity; 84.6% specificity), whereas UIP was correctly diagnosed in 73.3% of cases (84.6% sensitivity; 76.5% specificity). An 80% agreement was achieved between the HRCT and histological findings in the whole case series (73% sensitivity, 87% specificity, p<0.01). CONCLUSIONS: The most important finding of our study was that a ground glass appearance equal to or greater than 15% is highly suggestive of NSIP. Therefore, our results could be useful to confirm a suggested diagnosis of NSIP
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
