Physico-chemical stability of eribulin mesylate containing concentrate and ready-to-administer solutions.
Objectives The aim of this study was to determine the stability of commercially available eribulin mesylate containing injection solution as well as diluted ready-to-administer solutions stored under refrigeration or at room temperature. Methods Stability was studied by a novel developed stability-indicating reversed-phase high-performance liquid chromatography (RP-HPLC) assay with ultraviolet detection (detection wavelength 200 nm). Triplicate test solutions of eribulin mesylate containing injection concentrate (0.5 mg/mL) and with 0.9% sodium chloride solution diluted ready-to-administer preparations (0.205 mg/mL eribulin mesylate in polypropylene (PP) syringes, 0.020 mg/mL eribulin mesyl…
Using genetically-defined rodent strains for the identification of hippocampal traits relevant for two-way avoidance behavior: a non-invasive approach
Genetically-defined rodent strains permit the identification of hippocampal traits which are of functional relevance for the performance of two-way avoidance behavior. This is exemplified here by analyzing the relationship between infrapyramidal mossy fibers (a tiny projection terminating upon the basal dendrites of hippocampal pyramidal neurons) and two-way avoidance learning in about 800 animals. The necessary steps include 1) identification of structural traits sensitive to selective breeding for extremes in two-way avoidance, 2) testing the robustness of the associations found by studying individual and genetical correlations between hippocampal traits and behavior, 3) establishing caus…
Economic evaluation of caspofungin vs liposomal amphotericin B for empirical therapy of suspected systemic fungal infection in the German hospital setting
As antifungal agents are frequently used in hematology and oncology, economic data on the empirical therapy of suspected systemic fungal infection are pivotal. Data were analyzed according to: (1) the rate of nephrotoxicity related to treatment with caspofungin in comparison to liposomal amphotericin B (L-AmB) from a randomized clinical trial, (2) the effect of nephrotoxicity on length of hospital stay from a European observational study, and (3) an example of total bottom-up cost in a department of hematology in Germany. All estimates include 95% confidence intervals (CI) using two-stage Monte Carlo simulation on binominal and Gaussian random variables from separate studies with comparable…
