Why Is Food Insecurity High Among U.S. Grandparents Who Are Caring For Grandchildren?, Madonna Harrington Meyer, Anna Delapaz

Population Health Research Brief Series

One in four grandparent-headed families report food insecurity, compared to one in seven among all families with children. Generally, the more care grandparents provide for their grandchildren, the more likely they are to be food insecure. This brief summarizes finding from interviews conducted in 2021 with U.S. adults ages 60 and older who are caring for their grandchildren. The authors summarize the factors contributing to food insecurity among grandparents and call for better policies to assist food-insecure grandparents providing care for their grandchildren as they grapple with inadequate funds, burdensome food assistance programs, inadequate transportation, shortages of fresh foods, and …

OBJECTIVE: To understand fellowship program directors' (FPDs) perspectives on facilitators and barriers to using entrustable professional activities (EPAs) in pediatric subspecialty training.

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 …

Selection, Initiation, Continuation, And Efficacy Of Reversible Contraception Among Enlisted U.S. Service Women In Their First Term Of Service From 2012 To 2020., Christina M. Roberts, Joshua M. Smalley, William P. Adelman, Larissa F. Weir, Elisabeth Hisle-Gorman

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Pregnancy is the second most common cause of limited duty days among active duty service members in the U.S. Military. Pregnancy accounts for 10% of all days on restricted duty, despite impacting a minority of active duty service members. One out of five service women will experience an unintended pregnancy every year despite the availability of no-cost contraception and reproductive healthcare. Young, single, junior enlisted service women experience the highest rate of unintentional pregnancy. Previous studies have demonstrated service branch-based variability in selection, initiation, and continuation of specific contraceptive methods related to service branch culture and access to contraception …

Acetic Acid: An Underestimated Metabolite In Ethanol-Induced Changes In Regulating Cardiovascular Function, Andrew D. Chapp, Zhiying Shan, Qing Hui Chen

Michigan Tech Publications

Acetic acid is a bioactive short-chain fatty acid produced in large quantities from ethanol metabolism. In this review, we describe how acetic acid/acetate generates oxidative stress, alters the function of pre-sympathetic neurons, and can potentially influence cardiovascular function in both humans and rodents after ethanol consumption. Our recent findings from in vivo and in vitro studies support the notion that administration of acetic acid/acetate generates oxidative stress and increases sympathetic outflow, leading to alterations in arterial blood pressure. Real-time investigation of how ethanol and acetic acid/acetate modulate neural control of cardiovascular function can be conducted by microinjecting compounds into autonomic …

Taxation And Corporate Governance, Reuven S. Avi-Yonah, Ariel Siman

Law & Economics Working Papers

In recent years, legal and economic research has shown a growing interest in the interaction between corporate governance and taxation. Some specific aspects have drawn more interest, particularly the tax rules related to the remuneration of directors, measures taken by management in the context of market for corporate control, and the double taxation of inter-corporate dividends. However, there is still little legal literature on many other aspects of the interplay between the two systems, and several authors have identified this gap in the literature and the dire need for further study in this “fertile area of research.” The aim of …

Crispr Screening Identifies Bet And Mtor Inhibitor Synergy In Cholangiocarcinoma Through Serine Glycine One Carbon, Yan Zhu, Dengyong Zhang, Pooja Shukla, Young-Ho Jung, Prit Benny Malgulwar, Sharmeen Chagani, Medina Colic, Sarah Benjamin, John A Copland, Lin Tan, Philip L Lorenzi, Milind Javle, Jason T Huse, Jason Roszik, Traver Hart, Lawrence N Kwong

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, Koji Mizuhashi, Naoko Sakagami, Wanida Ono, 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 …

Intratumoral Biosynthesis Of Gold Nanoclusters By Pancreatic Cancer To Overcome Delivery Barriers To Radiosensitization, Aaron S Schwartz-Duval, Yuri Mackeyev, Iqbal Mahmud, Philip L Lorenzi, Mihai Gagea, Sunil Krishnan, Konstantin V Sokolov

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 …

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 …

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 …

“There’S So Much History”: Shared Parenting Dynamics In Kinship Families, Amanda Klein-Cox, Angela Tobin, Ramona Denby

Social Work Faculty Research

Shared parenting, when adults collaborate in childrearing, is a practice of interest for children in out-of-home care. Yet, little is known about its feasibility and outcomes for kinship families who have preexisting relationships with birth parents. This article shares qualitative results from focus groups that explored participants’ experiences and attitudes toward shared parenting. The sample comprised 25 kinship caregivers and 34 child welfare professionals. Findings revealed that shared parenting within kinship families is often less feasible than desired. This article identifies barriers and facilitators of shared parenting, offers a shared parenting typology, and explores implications for policy and practice.

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 …

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

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. …

There is an urgent need for new antibiotics given the rise of antibiotic resistance, and succinyl-diaminopimelate desuccinylase (DapE, E.C. 3.5.1.18) has emerged as a promising bacterial enzyme target. DapE from Haemophilus influenzae (HiDapE) has been studied and inhibitors identified, but it is essential to explore DapE from different species to assess selective versus broad-spectrum therapeutics. We have determined the structure of DapE from the ESKAPE pathogen Acinetobacter baumannii (AbDapE) and studied inhibition by known inhibitors of HiDapE. AbDapE is inhibited by captopril and sulfate comparable to HiDapE, but AbDapE was not significantly …

The role of hematopoietic Hedgehog signaling in myeloproliferative neoplasms (MPNs) remains incompletely understood despite data suggesting that Hedgehog (Hh) pathway inhibitors have therapeutic activity in patients. We aim to systematically interrogate the role of canonical vs. non-canonical Hh signaling in MPNs. We show that Gli1 protein levels in patient peripheral blood mononuclear cells (PBMCs) mark fibrotic progression and that, in murine MPN models, absence of hematopoietic Gli1, but not Gli2 or Smo, significantly reduces MPN phenotype and fibrosis, indicating that GLI1 in the MPN clone can be activated in a non-canonical fashion. Additionally, we establish that hematopoietic Gli1 has a …

Neural Correlates Of Automatic Emotion Regulation And Their Association With Suicidal Ideation In Adolescents During The First 90-Days Of Residential Care, Matthew Dobbertin, Karina S Blair, Joseph Aloi, Sahil Bajaj, Johannah Bashford-Largo, Avantika Mathur, Ru Zhang, Erin Carollo, Amanda Schwartz, Jaimie Elowsky, J L Ringle, Patrick Tyler, R James Blair

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. …

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 …
