Sleep fragmentation (SF) is a common occurrence and constitutes major characteristic of obstructive sleep apnea (OSA). SF has been implicated in multiple OSA-related morbidities, but it unclear whether underlies any the cardiovascular morbidities OSA. We hypothesized that long-term exposures may lead to endothelial dysfunction altered vessel wall structure. Adult male C57BL/6J mice were fed normal chow exposed daylight or control (CTL) for 20 weeks. Telemetric blood pressure function...

Mental health issues, which can be difficult to diagnose, are a growing concern worldwide. For effective care and support, early detection of mood-related concerns is paramount importance. Typically, survey based instruments including Ecologically Momentary Assessments (EMA) Day Reconstruction Method (DRM) the method choice for assessing mood related health. While effective, these methods require some effort thus both compliance rates as well quality responses limited. As an alternative, We...

The intermittent hypoxia (IH) that characterizes sleep-disordered breathing impairs spatial learning and increases NADPH oxidase activity oxidative stress in rodents. We hypothesized green tea catechin polyphenols (GTPs) may attenuate IH-induced neurobehavioral deficits by reducing expression, lipid peroxidation, inflammation.To assess the effects of GTP administered drinking water on cognitive, inflammatory, responses to long-term (>14 d) IH during sleep male Sprague-Dawley rats.Cognitive...

Specific antimicrobial antibodies present in the sera of patients with inflammatory bowel disease (IBD) have been proven to be valuable serological biomarkers for diagnosis/prognosis disease. Herein we describe use a whole Escherichia coli proteome microarray as novel high throughput proteomics approach screen and identify new IBD. Each protein array, which contains 4,256 E. K12 proteins, was screened using individual serum from healthy controls (n = 39) clinically well characterized IBD (66...

Exposure to intermittent hypoxia, such as occurs in sleep-disordered breathing, is associated with oxidative stress, cognitive impairments, and increased neuronal apoptosis brain regions involved learning memory. Apolipoprotein E (ApoE) has been implicated neurodegenerative disorders, vitro studies suggest that one of the functions ApoE may be confer protection from oxidant stress-induced cell loss. Therefore, we hypothesized ApoE-deficient (ApoE−/−) mice would display impairments following...

Abstract Intermittent hypoxia (IH) during sleep, a hallmark of sleep apnea, is associated with neurobehavioral impairments, regional neurodegeneration and increased oxidative stress inflammation in rodents.

We report that mice deficient the cell surface receptor for PAF ( PAFR –/–), bioactive inflammation, are protected from spatial reference learning deficits IH. Furthermore, –/– exhibit...

Large language models (LLMs) have shown remarkable abilities to generate code. However, their ability develop software for physical computing and embedded systems, which requires cross-domain hardware knowledge, has not been thoroughly studied. We observe through our experiments a 15-user pilot study that even when LLMs fail produce working code, they can helpful reasoning about design tasks, as well specific debugging suggestions both novice expert developers. These results highlight the...

Background Eating behavior has a high impact on the well-being of an individual. Such involves not only when individual is eating, but also various contextual factors such as with whom and where eating what kind food eating. Despite relevance factors, most automated detection systems are designed to capture factors. Objective The aims this study were (1) design build smartwatch-based system that can detect meal episodes based dominant hand movements, (2) ecological momentary assessment (EMA)...

Deviant eating behavior such as skipping meals and consuming unhealthy has a significant association with mental well-being in college students. However, there is more to what an individual eats. While patterns form critical component of their well-being, insights assessments related the interplay remain under-explored theory practice. To bridge this gap, we use existing real-time detection system that captures context during examine how students’ associates particularly affect, anxiety,...

Human embryos are usually cultured to blastocyst stage by Day 5 or 6 after insemination. However, some grow slowly and reach at 7. Acceptable live birth rates have been reported transfer of 7 blastocysts resulted from fresh oocyte in vitro fertilization (IVF). It is unknown whether an extended embryo culture necessary for cryopreserved IVF obtain more transferrable blastocysts.In this study, 455 oocytes 57 cycles were warmed, inseminated, the resulting examine development culture.
