Introduction: Brain stimulation techniques are critical for unraveling the innerworkings of complex neuronal pathways governing both normal physiological function and pathologic states in neurological disorders. Focused ultrasound (FUS) is an emerging technique poised to significantly alter central nervous system (CNS) drug delivery and neuroscience research through non-invasive means. Magnetogenetics is a brain stimulation technique which may benefit from FUS technology in that alternating magnetic fields (AMF), like FUS, can pass through the skull without requiring surgery.

Methodology: Magnetogenetics involves the deposition of superparamagnetic iron-oxide nanoparticles (SPIONs) and overexpression of thermoreceptor transmembrane proteins (e.g. TRPV1 and TRPA1) in the brain. When …

Objectives: Human milk intake has many benefits which could influence outcomes in biliary atresia (BA). However, the role of human milk in BA has not been examined. We hypothesized that human milk intake would be associated with improved outcomes in BA.

Methods: We assessed the impact of any human milk (AHM) as compared to formula only (FO) intake before Kasai portoenterostomy (KP) on outcomes in 447 infants with BA using the PROBE database (NCT00061828) post hoc. The primary outcome was clearance of jaundice (COJ = total bilirubin (TB) < 2 mg/dL by 3 months post-KP). Secondary outcomes included 2-year survival with native liver (SNL), bilirubin levels, cholangitis, ascites, and growth. We assessed the fecal microbiome (n = 8) comparing AHM versus FO.

Results: At baseline, 211 infants received AHM and 215 received …

Pollinator populations are declining globally at an unprecedented rate, driven by factors such as pathogens, habitat loss, climate change, and the widespread application of pesticides. Although colony losses remain difficult to prevent, precision beekeeping has introduced non-invasive strategies for monitoring hive conditions. Acoustic data, combined with machine learning techniques, has proven effective in detecting stressors and specific events in honeybee colonies; however, such methodologies remain underexplored for stingless bees, a group of native pantropical pollinators. Meliponiculture, the practice of keeping stingless bees, is an expanding field that offers significant economic and conservation benefits. Stingless bees are particularly susceptible to pesticide …

We have previously shown that mice with a loss of C-type lectin-like type II (CLEC2), which have lymphatic dysfunction due to the role of CLEC2 in platelets for maintaining separation between the venous and lymphatic system, develop lung tertiary lymphoid organ (TLO) formation and lung injury that resembles an emphysema phenotype of chronic obstructive pulmonary disease (COPD). We now sought to investigate whether and how TLOs in these mice may play a pathogenic role in lung injury that is relevant to human disease. We found that inhibiting TLO formation using an anti-CD20 antibody in CLEC2-deficient mice partially blocked the development …

Extreme hypertriglyceridemia, defined as triglyceride (TG) levels ≥1000 mg/dL, is almost always indicative of chylomicronemia. The current diagnostic approach categorizes individuals with chylomicronemia into familial chylomicronemia syndrome (FCS; prevalence 1-10 per million), caused by the biallelic combination of pathogenic variants that impair the lipolytic action of lipoprotein lipase (LPL), or multifactorial chylomicronemia syndrome (MCS, 1 in 500). A pragmatic framework should emphasize the severity of the phenotype and the risk of complications. Therefore, we endorse the term "persistent chylomicronemia (PC)" defined as TG ≥1000 mg/dL in more than half of the measurements to encompass patients with the highest risk for …

Faculty, Staff and Students Publications

Intracellular lipid binding proteins (iLBPs) play crucial roles in lipid transport and cellular metabolism across the animal kingdom. Recently, a fat‐to‐neuron axis was described in Caenorhabditis elegans, in which lysosomal activity in the fat liberates polyunsaturated fatty acids (PUFAs) that signal to neurons and extend lifespan with durable fecundity. In this study, we investigate the structure and binding mechanisms of a lifespan‐extending lipid chaperone, lipid binding protein‐3 (LBP‐3), which shuttles dihomo‐γ‐linolenic (DGLA) acid from intestinal fat to neurons. We present the first high‐resolution crystal structure of LBP‐3, which reveals a classic iLBP fold with an unexpected and unique homodimeric …

The complex interactions between parasites, their hosts, and associated microbiota hold significant implications for host health and disease outcomes. Helminths like Ascaris lumbricoides and Ascaris suum can significantly alter the host's intestinal microbiota, affecting both parasite biology and host pathology. Despite extensive research on host-microbiota changes due to helminth infections, the study of helminth-associated microbiota remains limited. This study aims to characterize the microbiota associated with Ascaris larvae and surrounding host tissues at distinct developmental stages (day 4, day 8, day 14), during larval migration through the liver, lungs, and intestine, and its impact on the host's microbiota in a …

Understanding The Influence Of Image Enhancement On Underwater Object Detection: A Quantitative And Qualitative Study, Ashraf Saleem, Ali Awad, Sidike Paheding, Evan Lucas, Timothy C. Havens, Peter C. Esselman

Michigan Tech Publications

Underwater image enhancement is often perceived as a disadvantageous process to object detection. We propose a novel analysis of the interactions between enhancement and detection, elaborating on the potential of enhancement to improve detection. In particular, we evaluate object detection performance for each individual image rather than across the entire set to allow a direct performance comparison of each image before and after enhancement. This approach enables the generation of unique queries to identify the outperforming and underperforming enhanced images compared to the original images. To accomplish this, we first produce enhanced image sets of the original images using recent …

Monocytes and macrophages are sentinels of the immune system that distinguish themselves from other cells by expressing the beta isoform of the folate receptor (FRβ). Because FRβ does not bind folate until the monocyte/macrophage is exposed to immunosuppressive cytokines, the question naturally arose whether FRβ might also perform an immune-related function. To examine this matter, we compared the properties of wild type (WT) and FRβ knockout mice. We observe that FRβ knockout (KO) mice display autoimmune symptoms that can include alopecia, enlarged spleens, and dermatitis, despite having normal cellular folate levels. We further demonstrate that syngeneic tumors (TRAMP C2, MC38) …
