    Abstract Abstract: Two female athletes presented to clinic following a head injury and exhibited signs of concussion. Both athletes experienced exacerbation of symptoms secondary to dysautonomia related to concussion injury on the Buffalo Concussion Treadmill Test (BCTT). On repeat evaluation, both athletes exhibited neck pain with symptoms immediately provoked by palpation of the occipital nerves. After a third occipital nerve block, both athletes had complete resolution of symptoms and subsequently tolerated BCTT to the maximum rate of perceived exertion with no provoked symptoms. The athletes were cleared for return to sport without issue. These cases indicate a potential limitation in the utility of the BCTT for determining the etiology and management of concussion and postconcussion syndrome.

    Abstract The primary method used to audit honey bee (Apis mellifera Linnaeus, 1758 [Hymenoptera: Apidae]) colony strength for almond pollination services, Nasr et al.'s (1990) frame-top cluster count method, is a subjective visual audit that relies on an auditor's spot assessment and may lack rigor and repeatability. We created novel, open-source software for the analysis of frame-top cluster count photographic assessments to improve methodological rigor and repeatability. We evaluated 2 existing visual audit methods, created 3 novel audit method variations, and determined between-method conversion factors using linear modeling. The software has potential applications in apiological research, apiarist and orchardist colony auditing, as well as training future generations of apiarists in auditing techniques. The software enhances the rigor and repeatability of Nasr et al.'s (1990) frame-top cluster count population assessment. In this article, we introduce the novel open-source software and between-method regression equations and review the tested visual assessment methods and their application.

    Abstract Control of neurotransmission efficacy is central to theories of how the brain computes and stores information. Presynaptic G-protein coupled receptors (GPCRs) are critical in this problem as they locally influence synaptic strength and can operate on a wide range of time scales. Among the mechanisms by which GPCRs impact neurotransmission is by inhibiting voltage-gated calcium (Ca2+) influx in the active zone. Here, using quantitative analysis of both single bouton Ca2+ influx and exocytosis, we uncovered an unexpected non-linear relationship between the magnitude of action potential driven Ca2+ influx and the concentration of external Ca2+ ([Ca2+]e). We find that this unexpected relationship is leveraged by GPCR signaling when operating at the nominal physiological set point for [Ca2+]e, 1.2 mM, to achieve complete silencing of nerve terminals. These data imply that the information throughput in neural circuits can be readily modulated in an all-or-none fashion at the single synapse level when operating at the physiological set point.

    Abstract Background: Research suggests a link between deficiencies in omega-3 long-chain polyunsaturated fatty acids (LCPUFAs) and impulsivity among psychiatric populations. However, this association is less evident in non-clinical populations. As omega-3 LCPUFAs are predominantly sourced through fish consumption, non-fish dieters may be more vulnerable to higher impulsivity.
    Methods: This cross-sectional observational study explored the association between lower intakes of omega-3 LCPUFA food sources and higher self-reported measures of impulsivity among healthy adults consuming non-restricted, vegetarian, and vegan diets.
    Results: The results from the validated Food Frequency Questionnaire showed significantly lower estimated omega-3 LCPUFA intakes among vegans and vegetarians when compared with people consuming non-restricted diets. Furthermore, although all groups scored within the normal range of impulsivity measures, vegans scored comparatively higher. Vegans also scored significantly higher in impulsivity control relating to attention than those consuming non-restricted diets.
    Conclusions: The significantly lower omega-3 LCPUFA dietary intakes in the vegan diets were associated with higher scores in the second-order attentional aspect of self-reported impulsiveness.

    Abstract Pain is a prevalent biopsychosocial condition that poses a significant challenge to healthcare providers, contributes substantially to a disability, and is a major economic burden worldwide. An overreliance on opioid analgesics, which primarily target the μ-opioid receptor, has caused devastating morbidity and mortality in the form of misuse and overdose-related death. Thus, novel analgesic medications are needed that can effectively treat pain and provide an alternative to opioids. A variety of cellular ion channels contribute to nociception, the response of the sensory nervous system to a noxious stimulus that commonly leads to pain. Ion channels involved in nociception may provide a suitable target for pharmacologic modulation to achieve pain relief. This narrative review summarizes the evidence for two ion channels that merit consideration as targets for non-opioid pain medications: ryanodine receptors (RyRs), which are intracellular calcium channels, and hyperpolarization-activated cyclic nucleotide-gated (HCN) channels, which belong to the superfamily of voltage-gated K+ channels. The role of these channels in nociception and neuropathic pain is discussed and suitability as targets for novel analgesics and antihyperalgesics is considered.
