Low reproducibility rates within life science research undermine cumulative knowledge production and contribute to both delays and costs of therapeutic drug development. An analysis of past studies indicates that the cumulative (total) prevalence of irreproducible preclinical research exceeds 50%, resulting in approximately US$28,000,000,000 (US$28B)/year spent on preclinical research that is not reproducible-in the United States alone. We outline a framework for solutions and a plan for long-term improvements in reproducibility rates that will help to accelerate the discovery of life-saving therapies and cures.

Aims: This study aimed to determine the robustness, reproducibility and representativeness of the landmark Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation (AF) (ARISTOTLE) and Rivaroxaban Once Daily Oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in AF (ROCKET AF) randomised trials through replication in an observational AF patient registry.
Methods And Results: Patients from the Global Anticoagulant Registry in the FIELD (GARFIELD)-AF registry treated with apixaban, rivaroxaban or vitamin K antagonist (VKA) were assessed for eligibility for the ARISTOTLE and ROCKET AF trials. HRs of apixaban and rivaroxaban versus comparator for stroke/systemic embolism, major bleeding and all-cause mortality within 2 years follow-up were calculated using propensity score overlap-weighted Cox models.

A label-free photoelectrochemical (PEC) sensor for detecting theophylline (TP) was exploited based on electrodes modified with a nanocomposite of polydopamine nanospheres (PDSs) and gold nanoparticles (AuNPs). PDS particles were prepared by oxidative autopolymerization, and their reducibility was utilized in one step to reduce the gold nanoparticles . The AuNPs-PDS/ZnS PEC sensor was constructed by electrochemical deposition and drop coating.

This study evaluates mathematical tools (principal component analysis, dynamic time warping, and the Kolmogorov-Smirnov hypothesis test) to analyse global and local data from dynamic signatures to reduce subjectivity and increase the reproducibility of handwriting examination using a two-step approach. A dataset composed of 1 800 genuine signature samples, 870 simulated signatures, and 60 disguises (30 formally similar or "autosimulated" and 30 random but different from usual) provided by 30 volunteers was collected. The first step involved global data analysis using principal component analysis and a hypothesis test performed for 62 global characteristics, and associations of these characteristics were analysed through calculations of multivariate distance followed by a hypothesis test.

The ZrO-embedded carboxy-functionalized -BN composite, combined with graphene oxide (GO), formed a novel BN-COOH@ZrO/GO composite. Structural characterization through IR, Raman spectroscopy, powder X-ray diffraction, and X-ray photoelectron spectroscopy supported the successful preparation of the composite, while scanning electron microscopy and transmission electron microscopy revealed its surface morphology and the presence of component materials. UV-vis spectroscopy (solid state) further supported these findings.
