The sabre‐toothed blennies (tribe Nemophini) are renowned for vivid colouration and several evolutionary adaptations, including a venom that resembles opioids in both chemistry and function. The genus Plagiotremus contains 11 species distributed across the Indo‐Pacific and Red Sea, including two nominal species endemic to Hawai'i. Here, we use mitochondrial COI and cytb in addition to select morphological characters to examine...

We reported previously that diet-induced obesity exacerbates early-stage Alzheimer’s disease (AD)–like pathology in TgF344-AD rats. Those findings also suggested that they may be prone to weight gain during early AD development, raising the possibility of early hypothalamic dysfunction. In this study, we investigate this by determining whether hypothalamic soluble amyloid-β 40 (Aβ 40 ) and amyloid-β 42 (Aβ 42 ) are detectable...
