Comparing The Trends Of Postpartum Depression Screening Scores During And Before The Covid-19 Pandemic, Elif S. Duran, Dung Dang, Tony Ogburn

Research Colloquium

Introduction: Postpartum depression includes major and minor depressive disorder affecting women in the time period after childbirth. The studies reviewed in our literature found that the COVID-19 pandemic has increased the risk of postpartum depression for women. Our study location, the Rio Grande Valley is one of the hardest hit locations by the COVID-19 pandemic in the United States. Our patient population is also one with the higher risk factors for postpartum depression. As such, we are expecting the psychological impact of the pandemic to be even more magnified and thus, actions need to be taken to support the vulnerable …

2020-Current year OA Pubs

Circadian rhythm dysfunction is a hallmark of Parkinson disease (PD), and diminished expression of the core clock gene Bmal1 has been described in patients with PD. BMAL1 is required for core circadian clock function but also serves nonrhythmic functions. Germline Bmal1 deletion can cause brain oxidative stress and synapse loss in mice, and it can exacerbate dopaminergic neurodegeneration in response to the toxin MPTP. Here we examined the effect of cell type-specific Bmal1 deletion on dopaminergic neuron viability in vivo. We observed that global, postnatal deletion of Bmal1 caused spontaneous loss of tyrosine hydroxylase+ (TH+) dopaminergic neurons in the substantia …


Targeting Efferocytosis In Inflammaging, Ivan K H Poon, Kodi S Ravichandran Jan 2024

Targeting Efferocytosis In Inflammaging, Ivan K H Poon, Kodi S Ravichandran

2020-Current year OA Pubs

Rapid removal of apoptotic cells by phagocytes, a process known as efferocytosis, is key for the maintenance of tissue homeostasis, the resolution of inflammation, and tissue repair. However, impaired efferocytosis can result in the accumulation of apoptotic cells, subsequently triggering sterile inflammation through the release of endogenous factors such as DNA and nuclear proteins from membrane permeabilized dying cells. Here, we review the molecular basis of the three key phases of efferocytosis, that is, the detection, uptake, and degradation of apoptotic materials by phagocytes. We also discuss how defects in efferocytosis due to the alteration of phagocytes and dying cells …


The Effect Of Various Polyphenols On Associative Memory Loss And Dementia In A Drosophila Melanogaster Model Of Alzheimer’S Disease, Anagha Gowda Jan 2024

The Effect Of Various Polyphenols On Associative Memory Loss And Dementia In A Drosophila Melanogaster Model Of Alzheimer’S Disease, Anagha Gowda

Journal of the South Carolina Academy of Science

Alzheimer’s Disease (AD), a prominent neurodegenerative disease (NDD), is the seventh leading cause of death in the United States; however, little is known about prevention. As a result, polyphenols (plant-based compounds) and other natural substances have been studied for their therapeutic potential in improving cognition and memory in AD cases. While the impacts of each polyphenol (phenolic acids, flavonoids, stilbenes, and lignans) contain fundamental similarities, each varies slightly in its impacts on the brain.The purpose of this study was to examine the impacts of polyphenol subgroups on associative memory in AD, tested by building an olfactory association, through the use …

METHODS: We performed a qualitative study of FPDs, balancing subspecialty, program size, geographic region and current uses of EPAs. A study coordinator conducted 1-on-1 interviews using a semistructured approach to explore EPA use or nonuse and factors supporting or preventing their use. Investigators independently coded transcribed interviews using an inductive approach and the constant comparative method. Group discussion informed code structure development and refinement. Iterative data collection and analysis continued until theoretical sufficiency was achieved, yielding a thematic …


Multivalent Epigraph Hemagglutinin Vaccine Protects Against Influenza B Virus In Mice, Erika M. Petro-Turnquist, Brigette Corder Kampfe, Amber Gadeken, Matthew J. Pekarek, Eric A. Weaver Jan 2024

Multivalent Epigraph Hemagglutinin Vaccine Protects Against Influenza B Virus In Mice, Erika M. Petro-Turnquist, Brigette Corder Kampfe, Amber Gadeken, Matthew J. Pekarek, Eric A. Weaver

Nebraska Center for Virology: Faculty Publications

Influenza B virus is a respiratory pathogen that contributes to seasonal epidemics, accounts for approximately 25% of global influenza infections, and can induce severe disease in young children. While vaccination is the most commonly used method of preventing influenza infections, current vaccines only induce strain-specific responses and have suboptimal efficacy when mismatched from circulating strains. Further, two influenza B virus lineages have been described, B/Yamagatalike and B/Victoria-like, and the limited cross-reactivity between the two lineages provides an additional barrier in developing a universal influenza B virus vaccine. Here, we report a novel multivalent vaccine using computationally designed Epigraph hemagglutinin proteins …

Health & Biomedical Sciences Faculty Publications

Simple Summary

Most neurofibromatosis type 1 (NF1) patients present with neurological issues in parallel with abnormal brain white matter and myelin. Although links for NF1 neuropathophysiology and abnormal myelin were proposed long ago, no current data can openly support or refute this idea. Various studies suggest that Nf1 mutations affect myelin biology and function, but any impact on learning/memory remains unclear. Here, we show that mice with an Nf1 mutation induced in adult myelinating cells present learning, but not memory, issues in a voluntary fine motor skill test, the complex wheel (CW). The specific parameters shaping CW learning curves are …

Sex-Specific Negative Affect-Like Behaviour And Parabrachial Nucleus Activation Induced By Bnst Stimulation In Adult Mice With Adolescent Alcohol History, Lucas Albrechet-Souza, Chelsea R. Kasten, Natalia B. Bertagna, Tiffany A. Wills

School of Medicine Faculty Publications

Adolescent alcohol use is a strong predictor for the subsequent development of alcohol use disorders later in life. Additionally, adolescence is a critical period for the onset of affective disorders, which can contribute to problematic drinking behaviours and relapse, particularly in females. Previous studies from our laboratory have shown that exposure to adolescent intermittent ethanol (AIE) vapour alters glutamatergic transmission in the bed nucleus of the stria terminalis (BNST) and, when combined with adult stress, elicits sex-specific changes in glutamatergic plasticity and negative affect-like behaviours in mice. Building on these findings, the current work investigated whether BNST stimulation could substitute …

The heterogeneity of the whole-exome sequencing (WES) data generation methods present a challenge to a joint analysis. Here we present a bioinformatics strategy for joint-calling 20,504 WES samples collected across nine studies and sequenced using ten capture kits in fourteen sequencing centers in the Alzheimer's Disease Sequencing Project. The joint-genotype called variant-called format (VCF) file contains only positions within the union of capture kits. The VCF was then processed specifically to account for the batch effects arising from the use of different capture kits from different studies. We identified 8.2 million autosomal variants. 96.82% of the variants are high-quality, and …

Faculty, Staff and Student Publications

Patients with cholangiocarcinoma have poor clinical outcomes due to late diagnoses, poor prognoses, and limited treatment strategies. To identify drug combinations for this disease, we have conducted a genome-wide CRISPR screen anchored on the bromodomain and extraterminal domain (BET) PROTAC degrader ARV825, from which we identified anticancer synergy when combined with genetic ablation of members of the mTOR pathway. This combination effect was validated using multiple pharmacological BET and mTOR inhibitors, accompanied by increased levels of apoptosis and cell cycle arrest. In a xenograft model, combined BET degradation and mTOR inhibition induced tumor regression. Mechanistically, the 2 inhibitor classes converged …

Hedgehog Activation Promotes Osteogenic Fates Of Growth Plate Resting Zone Chondrocytes Through Transient Clonal Competency, Shion Orikasa, Yuki Matsushita, Hiroaki Manabe, Michael Fogge, Zachary Lee, Naoko Sakagami, Noriaki Ono

Faculty, Staff and Student Publications

The resting zone of the postnatal growth plate is organized by slow-cycling chondrocytes expressing parathyroid hormone-related protein (PTHrP), which include a subgroup of skeletal stem cells that contribute to the formation of columnar chondrocytes. The PTHrP-Indian hedgehog feedback regulation is essential for sustaining growth plate activities; however, molecular mechanisms regulating cell fates of PTHrP+ resting chondrocytes and their eventual transformation into osteoblasts remain largely undefined. Here, in a mouse model, we specifically activated Hedgehog signaling in PTHrP+ resting chondrocytes and traced the fate of their descendants using a tamoxifen-inducible Pthrp-creER line with patched-1-floxed and tdTomato reporter alleles. Hedgehog-activated PTHrP+ chondrocytes …

Faculty, Staff and Student Publications

Background: Suicide is the second leading cause of death for adolescents in the United States. However, relatively little is known about the forms of atypical neuro-cognitive function that are correlates of suicidal ideation (SI). One form of cognitive/affective function that, when dysfunctional, is associated with SI is emotion regulation. However, very little work has investigated the neural correlates of emotion dysregulation in adolescents with SI.

Methods: Participants (N = 111 aged 12-18, 32 females, 31 [27.9%] reporting SI) were recruited shortly after their arrival at a residential care facility where they had been referred for behavioral and mental health problems. …


Trex2 Deficiency Suppresses Spontaneous And Genotoxin-Associated Mutagenesis, Teresa Marple, Mi Young Son, Xiaodong Cheng, Jun Ho Ko, Patrick Sung Jan 2024

Trex2 Deficiency Suppresses Spontaneous And Genotoxin-Associated Mutagenesis, Teresa Marple, Mi Young Son, Xiaodong Cheng, Jun Ho Ko, Patrick Sung

Faculty, Staff and Student Publications

TREX2, a 3'-5' exonuclease, is a part of the DNA damage tolerance (DDT) pathway that stabilizes replication forks (RFs) by ubiquitinating PCNA along with the ubiquitin E3 ligase RAD18 and other DDT factors. Mismatch repair (MMR) corrects DNA polymerase errors, including base mismatches and slippage. Here we demonstrate that TREX2 deletion reduces mutations in cells upon exposure to genotoxins, including those that cause base lesions and DNA polymerase slippage. Importantly, we show that TREX2 generates most of the spontaneous mutations in MMR-mutant cells derived from mice and people. TREX2-induced mutagenesis is dependent on the nuclease and DNA-binding attributes of TREX2. …

Faculty, Staff and Student Publications

Nanoparticle delivery to solid tumors is a prime challenge in nanomedicine. Here, we approach this challenge through the lens of biogeochemistry, the field that studies the flow of chemical elements within ecosystems as manipulated by living cellular organisms and their environments. We leverage biogeochemistry concepts related to gold cycling against pancreatic cancer, considering mammalian organisms as drivers for gold nanoparticle biosynthesis. Sequestration of gold nanoparticles within tumors has been demonstrated as an effective strategy to enhance radiotherapy; however, the desmoplasia of pancreatic cancer impedes nanoparticle delivery. Our strategy overcomes this barrier by applying an atomic-scale agent, ionic gold, for intratumoral …
