DNA damage photo-induced by chloroharmine isomers: hydrolysis versus oxidation of nucleobases
2018
Photodynamic therapy (PDT) is an emerging clinical treatment currently being used against a wide range of both cancerous and noncancerous diseases. The search for new active photosensitizers as well as the development of novel selective delivery systems are the major challenges faced in the application of PDT. We investigated herein three chloroharmine derivatives (6-, 8- and 6,8-dichloroharmines) with quite promising intrinsic photochemical tunable properties and their ability to photoinduce DNA damage in order to elucidate the underlying photochemical mechanisms. Data revealed that the three compounds are quite efficient photosensitizers. The overall extent of photo-oxidative DNA damage i…
A method for quantifying atrial fibrillation organization based on wave-morphology similarity
2002
A new method for quantifying the organization of single bipolar electrograms recorded in the human atria during atrial fibrillation (AF) is presented. The algorithm relies on the comparison between pairs of local activation waves (LAWs) to estimate their morphological similarity, and returns a regularity index (/spl rho/) which measures the extent of repetitiveness over time of the detected activations. The database consisted of endocardial data from a multipolar basket catheter during AF and intraatrial recordings during atrial flutter. The index showed maximum regularity (/spl rho/=1) for all atrial flutter episodes and decreased significantly when increasing AF complexity as defined by W…
Monte Carlo calculation of the TG-43 dosimetric parameters of a new BEBIG Ir-192 HDR source
2005
Background and purpose: High dose rate (HDR) brachytherapy is a highly extended practice in clinical brachytherapy today. Quality dose rate distribution datasets of the HDR sources used in a clinical treatment are required. Because of the different source designs, a specific dosimetry dataset is required for each source model. In the recently published BRAPHYQS-ESTRO Report, an overview of available dosimetric data for all HDR Ir-192 sources is given, pointing out the lack of data for one of the sources that is used by the BEBIG MultiSource afterloading system (BEBIG GmbH, Germany). The purpose of this study is to obtain detailed dose rate distributions in liquid water media around this sou…
A Multicentre, Randomised, Controlled Trial of a Combined Clinical Treatment for First-Episode Psychosis
2021
Introduction: There is evidence that early intervention contributes to improving the prognosis and course of first-episode psychosis (FEP). However, further randomised treatment clinical trials are needed. Objectives: The aim of this study was to compare the efficacy of a combined clinical treatment involving Cognitive Behavioural Therapy (CBT) as an adjunctive to treatment-as-usual (TAU) (CBT+TAU) versus TAU alone for FEP. Patients and methods: In this multicentre, single-blind, randomised controlled trial, 177 participants were randomly allocated to either CBT+TAU or TAU. The primary outcome was post-treatment patient functioning. Results: The CBT+TAU group showed a greater improvement in…
Diagnosis and novel clinical treatment strategies for pyoderma gangrenosum
2019
Introduction: Pyoderma gangrenosum (PG) is a noninfectious, reactive inflammatory neutrophilic dermatosis that is commonly associated with autoimmune and neoplastic disorders. There are emerging diagnostic tools and treatment options for PG.Area covered: The diagnosis of PG should be seriously considered when managing ulcers to avoid unnecessary medical and surgical complications with prompt and suitable treatment. There are no standardized treatment guidelines for PG, and current therapy largely depends on the severity and progression of the disease. Systemic corticosteroids, immunosuppressant therapy, and biologic agents remain mainstay therapies. In this article, we present a literature …
Monitoring of Plasma Concentrations of Psychotropic Drugs in Pharmacovigilance
2015
The primary aims of pharmacovigilance are supervision and prevention of medication-related problems under everyday conditions. Pharmacovigilance is an indication for monitoring plasma concentrations, i.e. conducting therapeutic drug monitoring (TDM). Using TDM, it can be clarified if observed unwanted drug effects may be attributed to abnormally high or low drug concentrations. Utmost benefits from TDM are obtained for pharmacovigilance when the method is adequately integrated into the clinical treatment process. How to do this is described in consensus guidelines for TDM in psychiatry. During the last 20 years, TDM was very successful for detection of multiple pharmacokinetic drug-drug int…
Bleaching in vital teeth : combined treatment vs in-office treatment
2019
Background The aim of this study was to verify that there will be greater whitening in teeth treated with combined bleaching than in those that have been applied a clinical one and to evaluate the efficiency of the clinical treatment, those cases in which it is not able, or it is not wanted, to carry out the home phase. Material and Methods They were used 66 extracted anterior human teeth, which were divided into two study groups. On the one hand, the clinical group (ClG) consisted of 33 teeth, which were treated with a clinical guideline using 37.5% hydrogen peroxide in a single session of 4 applications of 8 minutes. On the other hand, the combinate group (CoG) consisted of 33 teeth, whic…
Myofascial pain syndrome associated with trigger points: A literature review. (I): Epidemiology, clinical treatment and etiopathogeny
2009
Over the last few decades, advances have been made in the understanding of myofascial pain syndrome epidemiology, clinical characteristics and aetiopathogenesis, but many unknowns remain. An integrated hypothesis has provided a greater understanding of the physiopathology of trigger points, which may allow the development of new diagnostic, and above all, therapeutic methods, as well as the establishment of prevention policies and protocols by the health profession. Nevertheless, randomized studies are needed to provide a better understanding and detection of the different factors involved in the origin of trigger points.

Molecular bases of anorexia nervosa, bulimia nervosa and binge eating disorder: shedding light on the darkness
2017
International audience; Eating-disorders (EDs) consequences to human health are devastating, involving social, mental, emotional, physical and life-threatening aspects, concluding on impairment and death in cases of extreme anorexia nervosa. It also implies that people suffering an ED need to find psychiatric and psychological help as soon as possible to achieve a fully physical and emotional recovery. Unfortunately, to date, there is a crucial lack of efficient clinical treatment to these disorders. In this review, we present an overview concerning the actual pharmacological and psychological treatments, the knowledge of cells, circuits, neuropeptides, neuromodulators and hormones in the h…
