    A meta-analysis of threats to valid clinical inference in preclinical research of sunitinib

    Valerie C Henderson et al.
    Preclinical efficacy experiments testing sunitinib in animal cancer models display a lack of methodological rigour, with trim-and-fill analysis suggesting prominent publication bias that leads to an overestimation of treatment effect.

    Weight loss, insulin resistance, and study design confound results in a meta-analysis of animal models of fatty liver

    Harriet Hunter et al.
    Animal studies of fatty liver disease over-estimate the benefit of drugs due to publication bias and are confounded by off-target weight loss, illustrating the challenge of successful translational across species.

    Existence and functions of a kisspeptin neuropeptide signaling system in a non-chordate deuterostome species

    Tianming Wang et al.
    Identification and functional characterization of the first non-chordate kisspeptin neuropeptide system in the sea cucumber indicates the ancient origin of the intracellular signaling and physiological functions of this molecular system.

    CNTN5-/+or EHMT2-/+human iPSC-derived neurons from individuals with autism develop hyperactive neuronal networks

    Eric Deneault et al.
    Autism-associated iPSC-derived neurons mutant in CNTN5 or EHMT2 are hyperactive.
  1. Meta-Research: Questionable research practices may have little effect on replicability

    Rolf Ulrich, Jeff Miller
    Although questionable research practices inflate false positive rates, they have little effect on replicability because they also increase power.

    Research: Adequate statistical power in clinical trials is associated with the combination of a male first author and a female last author

    Willem M Otte et al.
    An analysis of 31,873 clinical trials shows that adequate statistical power was most often present in trials with a male first author and a female last author.
  2. Meta-Research: Gender variations in citation distributions in medicine are very small and due to self-citation and journal prestige

    Jens Peter Andersen et al.
    In studies of gender disparities in academia, increased focus is required on within-group variability and between-group overlap of distributions when interpreting and reporting results.

    Acid-base transporters and pH dynamics in human breast carcinomas predict proliferative activity, metastasis, and survival

    Nicolai J Toft et al.
    Cellular acidity, capacity for net acid extrusion, and expression of acid-base transporters in human breast carcinomas independently predict variation in proliferative activity, lymph node metastasis, and patient survival.

    Adjusting for age improves identification of gut microbiome alterations in multiple diseases

    Tarini S Ghosh et al.
    A multi-cohort analysis of 2,500 gut microbiomes and five major diseases discovers that disease-microbiome associations display specific age-centric trends, with diseases characterized by age-centric trends of species gain/loss.

    Metazoan evolution of glutamate receptors reveals unreported phylogenetic groups and divergent lineage-specific events

    David Ramos-Vicente et al.
    The animal phylogeny of glutamate receptors indicates that vertebrate types do not account for all receptor classes originated during evolution, neither are they the pinnacle of a linear evolutive process.
