The Crosstalk Between Amyloid-Β, Retina, And Sleep For The Early Diagnosis Of Alzheimer's Disease: A Narrative Review, Isaiah Lorenzo De Guia, Shaun Eslick, Sharon L. Naismith, Swathi Kanduri, Tejal M. Shah, Ralph N. Martins

Research outputs 2022 to 2026

Alzheimer's disease (AD) is the most common type of dementia, which is characterised by progressive memory loss and accumulation of hallmark markers amyloid-β (Aβ) and neurofibrillary tangles in the diseased brain. The current gold standard diagnostic methods have limitations of being invasive, costly, and not easily accessible. Thus, there is a need for new avenues, such as imaging the retina for early AD diagnosis. Sleep disruption is symptomatically frequent across preclinical and AD subjects. As circadian activity, such as the sleep-wake cycle, is linked to the retina, analysis of their association may be useful additions for achieving predictive AD diagnosis. …

Quality Improvement: Naloxone Prescribing Practices For Paitent With An Opioid Patient Prescriber Agreement, Moniqueca Helms

Walden Dissertations and Doctoral Studies

The Substance Abuse Mental Health and Human Services Administration (SAMHSA) has set guidelines for opioid prescribing practices. The core principles of SAMHSA are to prevent overdose abuse and to provide appropriate treatment for those with an opioid abuse disorder. The concern addressed by the Doctor of Nursing Practice project was the gap in physician education regarding a Best Practice Alert (BPA) in the Electronic Medical Record that appears when prescribing an opioid to a patient without cancer. The alert indicates best practice is to prescribe naloxone with the opioid prescription. The naloxone BPA education project was implemented using the exploration, …

Innate And Adaptive Immune Responses That Control Lymph-Borne Viruses In The Draining Lymph Node, Carolina R. Melo-Silva, Luis J. Sigal

Department of Microbiology and Immunology Faculty Papers

The interstitial fluids in tissues are constantly drained into the lymph nodes (LNs) as lymph through afferent lymphatic vessels and from LNs into the blood through efferent lymphatics. LNs are strategically positioned and have the appropriate cellular composition to serve as sites of adaptive immune initiation against invading pathogens. However, for lymph-borne viruses, which disseminate from the entry site to other tissues through the lymphatic system, immune cells in the draining LN (dLN) also play critical roles in curbing systemic viral dissemination during primary and secondary infections. Lymph-borne viruses in tissues can be transported to dLNs as free virions in …

Solid organ transplantation mobilizes myeloid cells, including monocytes and macrophages, which are central protagonists of allograft rejection. However, myeloid cells can also be functionally reprogrammed by perioperative costimulatory blockade to promote a state of transplantation tolerance. Transplantation tolerance holds promise to reduce complications from chronic immunosuppression and promote long-term survival in transplant recipients. We sought to identify different mediators of transplantation tolerance by performing single-cell RNA sequencing of acute rejecting or tolerized cardiac allografts. This led to the unbiased identification of the transcription factor, hypoxia inducible factor (HIF)-2α, in a subset of tolerogenic monocytes. Using flow cytometric analyses and mice …

Tumor cell plasticity contributes to intratumoral heterogeneity and therapy resistance. Through cell plasticity, some lung adenocarcinoma (LUAD) cells transform into neuroendocrine (NE) tumor cells. However, the mechanisms of NE cell plasticity remain unclear. CRACD (capping protein inhibiting regulator of actin dynamics), a capping protein inhibitor, is frequently inactivated in cancers. CRACD knockout (KO) is sufficient to de-repress NE-related gene expression in the pulmonary epithelium and LUAD cells. In LUAD mouse models, Cracd KO increases intratumoral heterogeneity with NE gene expression. Single-cell transcriptomic analysis showed that Cracd KO-induced NE cell plasticity is associated with cell de-differentiation and stemness-related pathway activation. The …

A Spatiotemporal Map Of Co-Receptor Signaling Networks Underlying B Cell Activation, Katherine J Susa, Gary A Bradshaw, Robyn J Eisert, Charlotte M Schilling, Marian Kalocsay, Stephen C Blacklow, Andrew C Kruse

Faculty, Staff and Student Publications

The B cell receptor (BCR) signals together with a multi-component co-receptor complex to initiate B cell activation in response to antigen binding. Here, we take advantage of peroxidase-catalyzed proximity labeling combined with quantitative mass spectrometry to track co-receptor signaling dynamics in Raji cells from 10 s to 2 h after BCR stimulation. This approach enables tracking of 2,814 proximity-labeled proteins and 1,394 phosphosites and provides an unbiased and quantitative molecular map of proteins recruited to the vicinity of CD19, the signaling subunit of the co-receptor complex. We detail the recruitment kinetics of signaling effectors to CD19 and identify previously uncharacterized …

Quercetin is an important phytochemical that belongs to the flavonoid group of plant pigments. It has potential benefits as an antioxidant, antiviral, and anti-inflammatory agent. However, the utilization of quercetin in aquaculture is not optimal. Hence, this study conducted a literature review to analyze the potential benefits of quercetin in aquaculture, especially for fish and prawn. Results showed that quercetin can be isolated from herbs using several methods, including sonication, maceration, and fractionation. Its amount in plants can be potentially determined using high-performance liquid chromatography and thin-layer chromatography. Some of the plants containing high quercetin levels include shallot, garlic, apple …
