Intermittent systemic exposure to lipopolysaccharide-induced inflammation disrupts hippocampal long-term potentiation and impairs cognition in aging male mice.

Brain Behav Immun

February 2023

Center for Basic and Translational Stroke Research, Rockefeller Neuroscience Institute, West Virginia University, Morgantown, WV 26505, USA; Department of Neuroscience, Rockefeller Neuroscience Institute, West Virginia University, Morgantown, WV 26505, USA.

Age-related cognitive decline, a common component of the brain aging process, is associated with significant impairment in daily functioning and quality of life among geriatric adults. While the complexity of mechanisms underlying cognitive aging are still being elucidated, microbial exposure and the multifactorial inflammatory cascades associated with systemic infections are emerging as potential drivers of neurological senescence. The negative cognitive and neurobiological consequences of a single pathogen-associated inflammatory experience, such as that modeled through treatment with lipopolysaccharide (LPS), are well documented.

The Flaw in Formalist Accounts of Circumvention Tourism.

J Law Med Ethics

November 2022

PENNSYLVANIA STATE COLLEGE (ERIE), BEHREND COLLEGE, ERIE, PA, USA.

Circumvention tourism is a form of medical tourism that occurs when individuals travel abroad to receive treatments that are a prohibited in their home county but permitted in a destination country. This paper explores this question: Guido Pennings, Richard Huxtable, and I. Glenn Cohen have all argued for what I call "formalist accounts" of circumvention tourism.

Exact results and the effect of monomer-monomer bond type for a grafted ideal chain.

Eur Phys J E Soft Matter

October 2022

Department of Physics, Sam Houston State University, Huntsville, TX, 77341, USA.

We determine the equilibrium chain end probability density [Formula: see text] for a one-dimensional ideal chain of N monomers grafted to a planar surface. This distribution is also the distribution function of a three-dimensional chain where the tangential dimensions y, z are integrated out of the distribution. With a small modification of the analysis of Erukhimovich, Johner, and Joanny for free chains near a wall, we are able to obtain exact results for [Formula: see text] for any monomer number N though with the restriction that the monomer-monomer bonds lengths are exponentially distributed.

Extracell Vesicles Circ Nucl Acids

September 2022

Department of Biology, School of Science, Penn State Erie, The Behrend College, Erie, PA 16563, USA.

Extracellular vesicles (EVs) are small, lipid-bound packages that are secreted by all cell types and have been implicated in many diseases, such as cancer and neurodegenerative disorders. Though limited, an exciting new area of EV research focuses on their role in the reproductive system and pregnancy. In males, EVs have been implicated in sperm production and maturation.

Various imaging techniques combined with machine learning (ML) models have been used to build computer-aided diagnosis (CAD) systems for breast cancer (BC) detection and classification. The rise of deep learning models in recent years, represented by convolutional neural network (CNN) models, has pushed the accuracy of ML-based CAD systems to a new level that is comparable to human experts. Existing studies have explored the usage of a wide spectrum of CNN models for BC detection, and supervised learning has been the mainstream.

This essay presents a challenge to the parental obligation objection. This objection is usually made by abortion opponents who argue that because child support laws hold men postnatally responsible for children they helped bring into existence (even when they did not intend to become parents), women too have prenatal parental responsibilities that should prevent them from ending pregnancies through abortions. My essay draws on recent publications in bioethics that distinguish procreative from parental responsibilities.

Article Synopsis
  • Single-point Tenax extractions are effective for estimating the bioaccessibility of hydrophobic contaminants like PCBs in various environments, with the potential for reusing the extraction beads under certain conditions.
  • A study was conducted to assess the reusability of Tenax beads by comparing PCB concentrations using both new and aged beads across multiple extraction cycles.
  • Results showed that, aside from certain PCB congeners that varied widely, the aged Tenax beads provided consistent bioaccessibility estimates, indicating no significant impact on their effectiveness after multiple uses.

The ethical indefensibility of heartbeat bills.

Bioethics

October 2022

Penn State Erie, The Behrend College, Erie, Pennsylvania.

Recently, several states in the United States have sought to adopt more restrictive abortion policies. Most have tried to enact "heartbeat bills" that prohibit most abortions once a fetal heartbeat becomes detectable. This article explores this question: Are heartbeat bills ethically defensible? I argue that they are not.

Extracellular vesicles (EVs) are nano-sized lipid-membrane bound structures that are released from all cells, are present in all biofluids, and contain proteins, nucleic acids, and lipids that are reflective of the parent cell from which they are derived. Proper separation of EVs from other components in a sample allows for characterization of their associated cargo and lends insight into their potential as intercellular communicators and non-invasive biomarkers for numerous diseases. In the current study, oligodendrocyte derived EVs were isolated from cell culture media using a combination of state-of-the-art techniques, including ultrafiltration and size exclusion chromatography (SEC) to separate EVs from other extracellular proteins and protein complexes.

Recent advances have witnessed a trending application of transfer learning in a broad spectrum of natural language processing (NLP) tasks, including question answering (QA). Transfer learning allows a model to inherit domain knowledge obtained from an existing model that has been sufficiently pre-trained. In the biomedical field, most QA datasets are limited by insufficient training examples and the presence of factoid questions.

There is growing interest in studying hormones beyond single 'snapshot' measurements, as recognition that individual variation in the endocrine response to environmental change may underlie many rapid, coordinated phenotypic changes. Repeated measures of hormone levels in individuals provide additional insight into individual variation in endocrine flexibility - that is, how individuals modulate hormone levels in response to the environment. The ability to quickly and appropriately modify phenotype is predicted to be favored by selection, especially in unpredictable environments.

Why Inconsistency Arguments Matter.

New Bioeth

March 2022

Penn State Erie, The Behrend College, Erie, PA, USA.

Abortion opponents are sometimes accused of having inconsistent beliefs, actions, and/or priorities. If they were consistent, they would regard spontaneous abortions to be a greater moral tragedy, or they would adopt more frozen in vitro fertilization embryos, or they would support more robust social welfare programmes for children and single parents, or so on and so forth. Nicholas Colgrove, Bruce Blackshaw, and Daniel Rodger have recently argued that such inconsistency arguments 'fail en masse.

Objective: Emerging adulthood (18-25 years) is a transitional and understudied developmental period. Yet, little is known about how specific symptoms of ADHD, as well as those from the related SCT domain, may differentially relate to one another during this period, if there are differences based on biological sex, or how closely results will align with adulthood.

Methods: We used network analysis techniques to explore the structure of ADHD and SCT symptoms within emerging adulthood, with additional comparisons between sexes as well as between emerging adulthood and adulthood.
