Masculine Ideals And Health In Older Men: Findings From The Wisconsin Longitudinal Study, Shane D. Burns, Patricia Drentea

APC Fund

How do older men’s masculine ideals affect their health? Are masculine activities involved in this relationship? Masculine identity upholds beliefs about masculine enactment. These beliefs can be detrimental to men and can lead to behaviors that can put undue stress on them. We examine how masculine ideals are associated with health and depressive symptomatology in older men. We used 2011 data from the Wisconsin Longitudinal Study (n = 2,594) to investigate how masculine ideals inform older men’s health and how participation in masculine activities might shape these outcomes.

Zirconia Implants: A Mapping Review, Steven J. Sadowsky Dec 2023

Zirconia Implants: A Mapping Review, Steven J. Sadowsky

Pacific Faculty Work

The advent of zirconia ceramics with excellent mechanical, biomechanical, and optical properties has made them attractive metal-free substitutes for titanium implants. Both animal and human studies have documented shortcomings with titanium implants. A mapping review of the current literature on three iterations of zirconia implant designs has been challenging due to heterogeneous success data and limited follow-up. Zirconia implants hold promise for a new generation of dental implants, but technical developments are needed for design and material enhancements that will need to be validated by long-term rigorous studies.

Enhanced Bmp Signaling In Cathepsin K-Positive Tendon Progenitors Induces Heterotopic Ossification, Hiroyuki Yamaguchi, Margaret Li, Megumi Kitami, Sowmya Swaminathan, Yuji Mishina, Yoshihiro Komatsu

Faculty, Staff and Student Publications

Heterotopic ossification (HO) is abnormal bone growth in soft tissues that results from injury, trauma, and rare genetic disorders. Bone morphogenetic proteins (BMPs) are critical osteogenic regulators which are involved in HO. However, it remains unclear how BMP signaling interacts with other extracellular stimuli to form HO. To address this question, using the Cre-loxP recombination system in mice, we conditionally expressed the constitutively activated BMP type I receptor ALK2 with a Q207D mutation (Ca-ALK2) in Cathepsin K-Cre labeled tendon progenitors (hereafter “Ca-Alk2:Ctsk-Cre”). Ca-Alk2:Ctsk-Cre mice were viable but they formed spontaneous HO in the Achilles tendon. Histological and molecular …

Enigmatic Cervicofacial Actinomycosis Post Radiotherapy - A Case Report, Amanda Phoon Nguyen Dec 2023

Enigmatic Cervicofacial Actinomycosis Post Radiotherapy - A Case Report, Amanda Phoon Nguyen

Journal of Dentistry Indonesia

Although thought to be uncommon, it is believed that cervicofacial actinomycosis is underreported due to frequent misdiagnosis. It has been called the “most misdiagnosed disease by experienced clinicians”. A wide range of dental procedures or trauma, including tooth eruption, may precipitate actinomycosis by enabling microorganisms to penetrate the deeper tissue layers via an entry point. This infective disease is significant due to its potentially aggressive and locally destructive nature. This case describes a patient diagnosed with cervicofacial actinomycosis. Her history prior to this was significant for proliferative verrucous leukoplakia, and T4aN0M0 (AJCC 7th Edition) squamous cell carcinoma of the right …

Faculty, Staff and Student Publications

Background

Medial temporal lobe (MTL) networks, including posterior-medial (PM) and anterior-temporal (AT) subnetworks, are early affected by Alzheimer’s disease (AD) pathologies (tau, neurodegeneration) and are critical for memory, which declines in AD. The biological pathways linking AD pathology, changes in MTL-AT-PM structural connectivity (SC), and cognitive decline, are unknown. Plasma protein levels reflect those in the cerebrospinal fluid, providing a low-invasive potential means of understanding molecular brain changes that occur in AD. These measures may help explain how AD pathology, MTL-AT-PM SC, and cognitive decline are linked at the molecular level. We used predefined aging-related plasma proteins from a meta-analysis …

Role-Reversibility, Ai, And Equitable Justice - Or: Why Mercy Cannot Be Automated, Stephen E. Henderson, Kiel Brennan-Marquez Dec 2023

Role-Reversibility, Ai, And Equitable Justice - Or: Why Mercy Cannot Be Automated, Stephen E. Henderson, Kiel Brennan-Marquez

JCLC Online

A few years ago, we developed the concept of “role-reversibility” in AI governance: the idea that it matters whether a party exercising judgment is reciprocally vulnerable to the effects of judgment. This idea, we argued, supplies a deontic reason to maintain certain spheres of human judgment even if (or when) truly intelligent machines become demonstrably superior in every utilitarian sense. While computer science remains far from that holy grail, generative AI is raging through systems as diverse as healthcare, finance, advertising, law, and academe, making it imperative to further shore up our claim. We do so by situating role-reversibility within …

Palmitate Induces Integrated Stress Response And Lipoapoptosis In Trophoblasts, Prakash Kumar Sahoo, Chandan Krishnamoorthy, Jennifer R. Wood, Corrine Hanson, Ann Anderson-Berry, Justin L. Mott, Sathish Kumar Natarajan

Department of Animal Science: Faculty Publications

Maternal obesity increases the risk of childhood obesity and programs the offspring to develop metabolic syndrome later in their life. Palmitate is the predominant saturated free fatty acid (FFA) that is transported across the placenta to the fetus. We have recently shown that saturated FFA in the maternal circulation as a result of increased adipose tissue lipolysis in third trimester of pregnancy induces trophoblast lipoapoptosis. Here, we hypothesized that palmitate induces integrated stress response by activating mitogen-activated protein kinases (MAPKs), endoplasmic reticulum (ER) stress and granular stress and lipoapoptosis in trophoblasts. Choriocarcinoma-derived third-trimester placental trophoblast-like cells (JEG-3 and JAR) referred …
