  • Concentration Dependent Feeding on Imidacloprid by Behaviorally Resistant House Flies, Musca domestica L. (Diptera: Muscidae) 25/09/2022
    The house fly (Musca domestica L.) is a cosmopolitan and synanthropic pest fly commonly associated with confined animal facilities, known to mechanically vector numerous disease-causing pathogens. Control of adult house flies often relies on insecticides formulated into insecticidal baits, though many baits have failed due to insecticide resistance. House fly resistance to imidacloprid, the most […]

  • The Incidence, Complications and Treatment of Iron Deficiency in Pregnancy 25/09/2022
    Iron deficiency and/or iron deficiency anemia complicate nearly 50% of pregnancies globally, negatively impacting both maternal and fetal outcomes. Iron deficiency can cause a range of symptoms that range from aggravating to debilitating including fatigue, poor quality of life, pagophagia and restless leg syndrome. Iron deficiency and iron deficiency anemia are also associated with maternal […]

  • Non-canonical roles of Siglecs: Beyond sialic acid-binding and immune cell modulation 24/09/2022
    Siglecs (Sialic acid-binding immunoglobulin-type lectins) are I-type lectins that bind with sialic acid ligands (Sia). Most are expressed on the surface of leukocytes and are involved in immune regulation and possess immune tyrosine-based inhibitory motif (ITIM) in the intracellular domain, thus leading to inhibition of the immune response. This signaling is instrumental in maintaining quiescence […]

  • Efficacy of Voice Therapy With Acapella Choice ® Device in Subjects With Vocal Fatigue Delivered Via Telepractice 24/09/2022
    CONCLUSION: Remote physiologic voice therapy with Acapella Choice device and water resistance therapy seem to be both effective to improve voice in subjects diagnosed with vocal fatigue. No differences should be expected between these therapeutic protocols when treating patients with vocal fatigue. Moreover, both are effective at reducing tiredness of voice, voice avoidance, physical discomfort […]

  • The promise of eye-tracking in the detection of concealed memories 24/09/2022
    There is a need for validated, theory-driven methods for memory detection. We review how physiological, neurophysiological, and oculomotor measures can be utilized to reveal concealed memories. Recent advances and future directions are discussed in light of the potential of eye-tracking to improve detection efficiency and resolve problems in real-world settings.

  • Late-Life Depression is Associated With Increased Levels of GDF-15, a Pro-Aging Mitokine 24/09/2022
    CONCLUSION: Our results suggest that depression in late life is associated with GDF-15, a marker of amplified age-related biological changes. GDF-15 is a novel and potentially targetable biological pathway between depression and accelerated aging, including cognitive aging.

  • A miniaturized bionic ocean-battery mimicking the structure of marine microbial ecosystems 24/09/2022
    Marine microbial ecosystems can be viewed as a huge ocean-battery charged by solar energy. It provides a model for fabricating bio-solar cell, a bioelectrochemical system that converts light into electricity. Here, we fabricate a bio-solar cell consisting of a four-species microbial community by mimicking the ecological structure of marine microbial ecosystems. We demonstrate such ecological […]

  • Spectral properties of physiological mirror activity: an investigation of frequency features and common input between homologous muscles 24/09/2022
    During unilateral contractions, muscular activation can be detected in both active and resting limbs. In healthy populations, the latter is referred to as physiological mirror activity (pMA). The study of pMA holds implications for clinical applications as well as the understanding of bilateral motor control. However, the underlying mechanisms of pMA remain to be fully […]

  • Targeting non-coding RNA family members with artificial endonuclease XNAzymes 24/09/2022
    Non-coding RNAs (ncRNAs) offer a wealth of therapeutic targets for a range of diseases. However, secondary structures and high similarity within sequence families make specific knockdown challenging. Here, we engineer a series of artificial oligonucleotide enzymes (XNAzymes) composed of 2'-deoxy-2'-fluoro-β-D-arabino nucleic acid (FANA) that specifically or preferentially cleave individual ncRNA family members under quasi-physiological conditions, […]

  • Mannan-binding lectin serine protease-2 (MASP-2) in human kidney and its relevance for proteolytic activation of the epithelial sodium channel 24/09/2022
    Proteolytic activation of the renal epithelial sodium channel (ENaC) is increased by aldosterone. The aldosterone-sensitive protease remains unidentified. In humans, elevated circulating aldosterone is associated with increased urinary extracellular vesicle (uEVs) excretion of mannan-binding lectin associated serine protease-2 (MASP-2). We hypothesized that MASP-2 is a physiologically relevant ENaC-activating protease. It was confirmed that MASP2 mRNA […]
