With rapid advancements in deep learning, automated animal behaviour quantification tools with high accuracy have emerged. In this study, we pioneere the use of both three-dimensional convolutional neural networks and self-attention mechanisms to develop the Automatic Emesis Detection (AED) tool for the quantification of emesis in S. murinus, achieving an overall accuracy of 98.92%. Specifically, we use motion-induced emesis videos as training datasets, with validation results demonstrating an accuracy of 99.42% for …

Effect Of Vitamin K Supplementation On Insulin Resistance: A Review, Samantha Mccord, Rebecca Willier, Kaitlyn Kirby, Kaylin Mahoney, Lance Dillon, Rileigh Rahrig, Brianna Lu, Joshua Honaker, Emily Eddy

Pharmacy and Wellness Review

Insulin resistance is one of the pathological hallmarks that leads to the development of type II diabetes mellitus (T2DM). Around 40% of people aged 18 to 44 living in the United States have insulin resistance. Recent research, coupled with a better understanding of how vitamin K functions in the body, suggests that this vitamin could potentially help reduce insulin resistance. Vitamin K is not included in the American Diabetes Association (ADA) guidelines for the treatment of insulin resistance, but it has been shown to have some benefits in patients with T2DM. It may also serve as a treatment option for …

Qualitative interviews were used to obtain patients' perspectives about lifestyle changes, and 3 quantitative questionnaires-the Readiness Ruler, Rate Your Plate, and the International Physical Activity Questionnaire-Short Form (IPAQ-SF)-were used to measure patients' readiness for lifestyle change, …

Antidiabetic Properties Of Prickly Pear (Opuntia Ficus-Indica) Fruit Extract, Kenzy Aidan Joseph Mckay

The Undergraduate Research Journal

Diabetes mellitus is a metabolic disorder that claims 1.5 million lives annually. Opuntia ficus-indica, commonly known as the prickly pear, has been commonly used in traditional folk medicine for its hypoglycemic properties. It has been claimed that it has antimicrobial and antioxidant properties as well. The plant is native to Mexico and is commonly found in the middle east and India and folk medicine from all of these areas have been using prickly pear medicinally for years. To test these claims an extract of locally sourced Opuntia ficus-indica was prepared using the flesh and seeds of the fruit. The …

For most researchers, academic publishing serves two goals that are often misaligned-knowledge dissemination and establishing scientific credentials. While both goals can encourage research with significant depth and scope, the latter can also pressure scholars to maximize publication metrics. Commercial publishing companies have capitalized on the centrality of publishing to the scientific enterprises of knowledge dissemination and academic recognition to extract large profits from academia by leveraging unpaid services from reviewers, creating financial barriers to research dissemination, and imposing substantial fees for open access. We present a set of perspectives exploring alternative models for communicating and disseminating scientific research. Acknowledging that …

Bilirubin Bioconversion To Urobilin In The Gut-Liver-Kidney Axis: A Biomarker For Insulin Resistance In The Cardiovascular-Kidney-Metabolic (Ckm) Syndrome, Zachary A. Kipp, Olufunto O. Badmus, David E. Stec, Brantley Hall, Terry D. Hinds Jr.

Markey Cancer Center Faculty Publications

The rising rates of obesity worldwide have increased the incidence of cardiovascular disease (CVD), making it the number one cause of death. Higher plasma bilirubin levels have been shown to prevent metabolic dysfunction and CVD. However, reducing levels leads to deleterious outcomes, possibly due to reduced bilirubin half-life that escalates the production of its catabolized product, urobilinogen, produced by gut bacteria and naturally oxidized to urobilin. Recent findings suggest that the involvement of the microbiome catabolism of bilirubin to urobilin and its absorption via the hepatic portal vein contributes to CVD, suggesting a liver-gut axis involvement. We discuss the studies …

Beyond Traditional Body Composition Metrics: Load-Capacity Indices Emerge As Predictors Of Cardiometabolic Outcomes—A Systematic Review And Meta-Analysis, Zhongyang Guan, Marianna Minnetti, Steven B. Heymsfield, Eleonora Poggiogalle, Carla M. Prado, Marc Sim, Blossom C.M. Stephan, Jonathan C.K. Wells, Lorenzo M. Donini, Mario Siervo

Research outputs 2022 to 2026

The adaptive and independent interrelationships between different body composition components have been identified as crucial determinants of disease risk. On the basis of this concept, the load-capacity model of body composition, which utilizes measurements obtained through nonanthropometric techniques such as dual-energy X-ray absorptiometry, was proposed. This model is typically operationalized as the ratio of metabolic load (adipose mass) to metabolic capacity (lean mass). In recent years, a series of load-capacity indices (LCIs) have been utilized to identify abnormal body composition phenotypes such as sarcopenic obesity (SO) and to predict the risk of metabolic, cardiovascular, and cognitive disorders. In this review, …

Obesity is a growing global health epidemic with limited orally administered therapeutics. Serotonin (5-HT) is one neurotransmitter which remains an excellent target for new weight-loss therapies, but a gap remains in understanding the mechanisms involved in 5-HT produced in the dorsal Raphe nucleus (DRN) and its involvement in meal initiation. Using an optogenetic feeding paradigm, we showed that the 5-HTDRN→arcuate nucleus (ARH) circuit plays a role in meal initiation. Incorporating electrophysiology and ChannelRhodopsin-2-Assisted Circuit Mapping, we demonstrated that 5-HTDRN neurons receive inhibitory input partially from GABAergic neurons in the DRN, and the 5-HT response can be enhanced by hunger. Additionally, …

Leptin Receptor Neurons In The Dorsomedial Hypothalamus Require Distinct Neuronal Subsets For Thermogenesis And Weight Loss, Marie Francois, Laura Kaiser, Yanlin He, Yong Xu, J Michael Salbaum, Sangho Yu, Christopher D Morrison, Hans-Rudolf Berthoud, Heike Münzberg

Children’s Nutrition Research Center Staff Publications

The dorsomedial hypothalamus (DMH) receives inputs from the preoptic area (POA), where ambient temperature mediates physiological adaptations of energy expenditure and food intake. Warm-activated POA neurons suppress energy expenditure via brown adipose tissue (BAT) projecting neurons in the dorsomedial hypothalamus/dorsal hypothalamic area (dDMH/DHA). Our earlier work identified leptin receptor (Lepr)-expressing, BAT-projecting dDMH/DHA neurons that mediate metabolic leptin effects. Yet, the neurotransmitter (glutamate or GABA) used by dDMH/DHALepr neurons remains unexplored and was investigated in this study using mice. We report that dDMH/DHALepr neurons represent equally glutamatergic and GABAergic neurons. Surprisingly, chemogenetic activation of glutamatergic and/or GABAergic dDMH/DHA neurons were capable …

β-Hydroxybutyrate (BHB) is an abundant ketone body. To date, all known pathways of BHB metabolism involve the interconversion of BHB and primary energy intermediates. Here, we identify a previously undescribed BHB secondary metabolic pathway via CNDP2-dependent enzymatic conjugation of BHB and free amino acids. This BHB shunt pathway generates a family of anti-obesity ketone metabolites, the BHB-amino acids. Genetic ablation of CNDP2 in mice eliminates tissue amino acid BHB-ylation activity and reduces BHB-amino acid levels. The most abundant BHB-amino acid, BHB-Phe, is a ketosis-inducible congener of Lac-Phe that activates hypothalamic and brainstem neurons and suppresses feeding. Conversely, CNDP2-KO mice exhibit …

Journal of Community Hospital Internal Medicine Perspectives

Purpose: The diagnosis and management of hypercalcemia in hospitalized patients can be challenging. Hypercalcemia is often associated with significant morbidity and end-organ damage which may delay a patient’s recovery.

Methods: We report a case series of three patients who underwent orthopedic procedures with intraoperative placement of vancomycin-loaded calcium sulfate beads. Patients had no known history of malignancy or excess intake of calcium, vitamin A or vitamin D. Laboratory workup showed low parathyroid (PTH) levels and normal PTH-related peptide levels. The temporal nature of the non-PTH mediated hypercalcemia in relation to implantation of the antibiotic beads suggests causality of exogenous calcium …
