Accumulation of amyloid-beta (Aβ42) senile plaques in the brain is a hallmark of Alzheimer's disease (AD). Although some drug have been approvaled recently, none has demonstrated robust disease-modifying outcome. The 3-deoxyanthocyanidins (3-DXA) and their derivatives represent a more stable class of polyphenols, present at uniquely high concentrations in sorghum grains. Although 3-DXA exhibit strong potential to modulate protein aggregation processes, their effects on AD pathology remain unexplored. In this study, we investigated the inhibitory effects of three 3-DXA derivatives, apigeninidin chloride (AC), luteolinidin chloride (LC), and 7-methoxy apigeninidin (7-MAC), on Aβ42 aggregation and associated neurotoxicity. Thioflavin T fluorescence assay was …

OBJECTIVE: To identify birthing parent and child factors associated with appropriate HCV testing for perinatally exposed infants and characterize HCV care for children with HCV.

DESIGN, SETTING, AND PARTICIPANTS: This cohort study included records on testing, care, and treatment for Massachusetts children perinatally exposed to HCV between 2014 and 2021 from a statewide health database linking statewide vital statistics, infectious disease surveillance data, substance use …

Mda5-Mavs And Interferon-Lambda Signaling In The Intestinal Epithelium Limit Murine Astrovirus Infection, Heyde Makimaa, Harshad Ingle, Leran Wang, Somya Aggarwal, Hongju Deng, Elizabeth A Kennedy, Lynne Foster, Yuhao Li, Megan T Baldridge

2020-Current year OA Pubs

Human astroviruses (HAstVs) are a global cause of pediatric gastroenteritis and can cause disseminated infection in immunocompromised hosts. Murine astrovirus (muAstV) causes acute asymptomatic infections in immunocompetent mice and chronic infection in immunodeficient models and has provided important insights into AstV pathogenesis in vivo. MuAstV can protect immunodeficient mice from other enteric viruses via robust induction of antiviral cytokine interferon-lambda (IFN-λ), with recent findings implicating goblet cells and enterocytes as both cell types infected by muAstV as well as potential sources of IFN-λ in vivo. However, the viral sensing pathways that regulate induction of IFN-λ, as well as the specific …

Intracranial Mesenchymal Tumor, Fet::Creb Fusion-Positive: An Integrative Analysis Of 81 Cases, Sharika Rajan, Robert Schmidt, Et Al.

2020-Current year OA Pubs

BACKGROUND: Intracranial mesenchymal tumors, FET::CREB fusion-positive (ICMT), show fusions involving FET RNA-binding protein family genes (EWSR1 or FUS) and CREB family of transcription factors (ATF1, CREB1, or CREM). The methylation signature(s), gene expression characteristics, and clinical behavior of this important tumor type require further characterization.

METHODS: We study the methylation profiles of 81 ICMT cases (61 newly profiled cases and 20 cases from publicly available sources). Clinicopathologic and genomic data were recorded for each case when available.

Obsessive-compulsive disorder (OCD) is a chronic, serious psychiatric disorder that affects 2%-3% of the population and is associated with high personal and societal costs. Genetic factors are estimated to explain roughly half the risk of developing OCD, and genomic studies are just beginning to identify common and rare genetic variants mediating this risk. A major goal of genomic studies is to yield insights into the etiology of OCD and identify molecular targets for the development of novel therapeutics. However, the overwhelming majority of subjects in existing genetic studies are of European ancestry, limiting the generalizability of these findings. To address …

Faculty, Staff and Students Publications

Background:

Sorting Nexin 27 (SNX27), a key regulator of synaptic receptor trafficking and endosomal recycling, has been implicated in maintaining synaptic homeostasis and cognitive function. To date, variants in SNX27 have been reported in a small number of patients across three publications with severe neurodevelopmental phenotypes. However, the genetic and functional landscape of SNX27-related disorders remains poorly understood, and further evidence is needed to confirm its association with disease and to better delineate the associated phenotype.

Methods and Results:

Two unrelated Pakistani families with a total of five affected individuals segregating a neurodevelopmental disorder were investigated via exome …

Upper Ocean Cycling Of Iron South Of The Polar Front: Biological Patterns And Processes, Luis M. Laglera, Santos-Echeandía, Viena Puigcorbé, Christine Klass, Dieter Wolf-Gladrow

Research outputs 2022 to 2026

Samples from the upper 300 m along the 52°S band, south of the Antarctic Polar Front in the Atlantic sector of the Southern Ocean, including a 3-week monitoring of a persistent bloom, were analyzed to advance our understanding of iron cycling and supply to recurrent phytoplankton blooms. We measured dissolved Fe (dFe, <0.2 μm) and labile particulate iron using a mild acid leach (pLFe^48h) targeting primarily detrital and fecal material. Particulate iron was partitioned into size classes to distinguish small, “slow” sinking particles (<53 μm) from large, “fast” sinking particles (>53 μm), while intermediate fractions were analyzed to investigate aggregation and export processes. Across all stations, dFe exhibited a consistent vertical structure, including a previously undescribed …

Advancing Fish Tissue Reference Material Development For Ag Nanoparticles Through A Perfusion Approach, Nathaniel J. Clark, Robert Clough, Adam Laycock, Rachel Smith, Richard D. Handy

School of Biological and Marine Sciences

There is a regulatory need for reliable methods to quantify nanoparticles in biological samples for the hazard assessment and bioaccumulation potential of engineered nanomaterials (ENMs). Single particle inductively coupled plasma mass spectrometry (SP-ICP-MS) is a promising technique, but its application is hindered by the lack of validated sample preparation procedures (e.g., solubilisation) and suitable biological reference materials. This study aimed to develop an in-house biological reference material for ENMs to support analytical method validation. Silver nanoparticles (Ag NPs) were introduced into rainbow trout via cardiac perfusion, with the gills and liver collected as target tissues. Tissues were homogenised using a …

The Importance Of Holistic Care: The Development And Implementation Of Spiritual Resources For Caregivers And Staff At Joni’S House El Salvador, Chloe Veilleux

Capstone Projects

It is within the occupational therapy (OT) scope of practice to not only address client needs related to mind, body, and spirit, but also those of caregivers as a means of fostering overall improved quality of life. Additionally, when OTs address spirituality and implement spiritual/spirituality-informed interventions, correlations of improved psychosocial factors such as well-being, motivation, and reduced stress have been shown, as well as improved hope and reduced burden for caregivers. There remains, however, a gap in the research and implementation of spiritually informed care and resources specifically as it pertains to caregivers of those with disabilities. To address this …

Defining Her2 Associated Proteogenomic Features In Breast Cancer And Extending To Gynecologic Cancers, Maya Anand

Theses

HER2 amplification is a well-established driver of breast cancer and serves as the primary basis for clinical classification and treatment selection. However, this framework assumes that HER2-driven tumor biology is defined solely by ERBB2 amplification or overexpression. The goal of this study was to evaluate whether HER2-associated signaling is represented as a pathway-level activation state and whether this framework could help identify tumors with clinically relevant HER2 activity beyond current routine classification methods. HER2-associated transcriptional programs were identified across three independent breast cancer cohorts, resulting in conserved gene sets (P76 and P25). Amplification-independent HER2 activation was assessed using the HER2 …

Variable Hybridization Rates Between F2 Fundulus Notatus Females, Jordan Tanaka

Honors Theses

Hybridization between two related species has been widely observed and offers a lens into complex evolutionary processes. Endogenous and exogenous factors affect hybrid fitness and diversification, and pre-zygotic and post-zygotic barriers affect species’ ability to hybridize. Female mate choice is a pre-zygotic isolation mechanism which is known to be more significant than male mate choice in many species, a trend which is linked to females often investing more energy into offspring. Detailing the ways in which these mechanisms operate is integral to understanding hybridization on a larger scale. The species examined here, Fundulus notatus and Fundulus olivaceous, are closely …

Evaluating The Environmental Parameters Impacting Spawning Movement Of Gulf Sturgeon (Acipenser Desotoi) In The Bouie River System., Olivia St. Germain

Honors Theses

The anadromous Gulf Sturgeon (Acipenser desotoi) is federally listed as “threatened” and is natal to seven rivers from Louisiana to Florida. Only one spawning reach for Gulf Sturgeon natal to the Pascagoula River has been verified via the collection of eggs and larvae; a reach of the lower Bouie River. This reach is anthropogenically modified by four gravel mining formations, hereafter referred to as pits. The greater depths associated with this area have prompted previous researchers to suggest that Gulf Sturgeon may over-summer in pit formations instead of migrating to downstream holding areas in the Pascagoula River after spawning. The …

An Insight Into The Venom Gland Proteome Of The Two-Spined Trap-Jaw Ant, Odontomachus Haematodus, Aaron Morgan

Honors Theses

Ants are ecologically important and highly abundant organisms, playing key roles in many ecosystems. One recently introduced species in the southeastern United States is Odontomachus haematodus (the two-spined trap-jaw ant), a South American native that has often been misidentified, contributing to limited research on its biology and venom composition. This study aimed to provide the first detailed characterization of the venom apparatus and proteome of O. haematodus. Specimens were collected and dissected, and venom-related proteins were extracted and analyzed using SDS-PAGE and tandem mass spectrometry (MS/MS-ESI). Confocal microscopy was also used to visualize the sting apparatus, including F-actin filaments and …

Bodies As Vessels: (Re)Production, Consumption, And Female Identity In The Handmaid’S Tale And Dawn, Shelby Clark

Honors Theses

This honors thesis examines how reproduction and food are used to signify power and impact female identity in Margaret Atwood’s The Handmaid's Tale and Octavia Butler’s Dawn. Both feminist dystopian novels portray societies that secure futurity through the commodification and management of women's domestic labor. The protagonist of each novel, Offred in The Handmaid's Tale and Lilith in Dawn, is responsible for ensuring the survival of humanity through forced reproduction and is additionally expected to produce or manage food. In this thesis, I argue that in both novels, female identity is reclaimed and affirmed as separate from a commodified state …
