PATIENT’S COMPLIANCE TO INTRAVESCICAL BCG IN ROUTINE CLINICAL PRACTICE, RETROSPECTIVE ANALYSIS OF 411 CONSECUTIVE PATIENTS.

2014

Aim of the study BCG maintenance for at least one year is advocated by urological guidelines as the best intravesical regimen in high-risk non muscle invasive bladder cancer (NMIBC), conservatively treated. Noteworthy, a relevant percentage of patients does not complete the planned treatment even if toxicity accounted for less that 10% of drop outs in recent multi-institutional trials. The aim of this study was to analyze the reasons for treatment interruption in everyday clinical practice. Materials and methods Consecutive patients affected by T1HG NMIBC undergoing conservative management with adjuvant BCG entered the study. The Connaught BCG strain was administered intravesically, at the …

Cytotoxicity of the Urokinase-Plasminogen Activator Inhibitor Carbamimidothioic Acid (4-Boronophenyl) Methyl Ester Hydrobromide (BC-11) on Triple-Neg…

BC-11 is an easily synthesized simple thiouronium-substituted phenylboronic acid, which has been shown to be cytotoxic on triple negative MDA-MB231 breast cancer cells by inducing a perturbation of cell cycle when administered at a concentration equal to its ED50 at 72 h (117 μM). Exposure of cells to BC-11, either pre-absorbed with a soluble preparation of the N-terminal fragment of urokinase-plasminogen activator (uPa), or in co-treatment with two different EGFR inhibitors, indicated that: (i) BC-11 acts via binding to the N-terminus of the enzyme where uPa- and EGF receptor-recognizing sites are present, thereby abrogating the growth-sustaining effect resulting from receptor binding

Intravenous Use of Methadone: Efficacy and Safety

2013

Parenteral methadone could be helpful in specific conditions, particularly in unstable conditions of when the oral route is unavailable. Intravenous methadone should be the preferred parenteral route, due to concerns about the local toxicity of subcutaneous route. This chapter assesses aspects regarding the pharmacokinetic issues, the clinical use, the problems associated with the use of intravenous methadone for chronic pain, as well as the perioperative use of intravenous methadone.

The role of mycotoxins in neurodegenerative diseases: current state of the art and future perspectives of research

2021

Abstract Mycotoxins are fungal metabolites that can cause various diseases in humans and animals. The adverse health effects of mycotoxins such as liver failure, immune deficiency, and cancer are well-described. However, growing evidence suggests an additional link between these fungal metabolites and neurodegenerative diseases. Despite the wealth of these initial reports, reliable conclusions are still constrained by limited access to human patients and availability of suitable cell or animal model systems. This review summarizes knowledge on mycotoxins associated with neurodegenerative diseases and the assumed underlying pathophysiological mechanisms. The limitations of the common in vivo…

Toxicity test of a dental commercial composite

2015

BACKGROUND: International rules must be followed for testing biosecurity in dental materials. A new brand of restorative material appeared in the market and regulations indicated that it should be tested for toxicity. OBJECTIVES: The aim of this study was to determine the 90-day sub chronic toxicity of one triethylene glycol dimethacrylate containing composite (MEDENTAL Light-Cure Composite™) orally administered to rats according to Organization for Economic Co-Operation and Development no. 48 guidelines and the requirements specified in the ISO 10993-11. MATERIAL AND METHODS: Wistar rats ate the polymerized composite during 90 days and were observed to determine changes in their behavior, …

Optimization of curation of the dataset with data on repeated dose toxicity

2015

Introduction: For some areas of risk assessment, the use of alter-native methods is supported by current directives and guidance(e.g. REACH, Cosmetics, BPD, PPP). According to OECD principles alternative methods need to be scientifically valid. Methods: Within a project on grouping and development of predictive models sup-ported by a grant of Federal Ministry of Education and Research, we curated a dataset based on RepDose and ELINCS database. The final dataset consists of rat repeated dose toxicity studies for 1022 com-pounds representing 28 endpoints as organ-effect-combinations. Toxicological and modelling experts did jointly the curation and selection of endpoints as an iterative proces…

Combining conventional chemotherapy and γδ T cell-based immunotherapy to target cancer-initiating cells.

2013

According to common beliefs, conventional anticancer chemotherapy is deleterious for the immune system. We have recently provided in vitro evidence indicating that conventional chemotherapy may potentiate, rather than impair, the long-term efficacy of γδ T cell-based anticancer immunotherapy.
