An multi-organ microphysiological system (MPS) to investigate the gut-to-brain translocation of neurotoxins.

The death of dopamine-producing neurons in the substantia nigra in the base of the brain is a defining pathological feature in the development of Parkinson's disease (PD). PD is, however, a multi-systemic disease, also affecting the peripheral nervous system and gastrointestinal tract (GIT) that interact via the gut-brain axis (GBA). Our dual-flow GIT-brain microphysiological system (MPS) was modified to investigate the gut-to-brain translocation of the neurotoxin trigger of PD, 1-methyl-4-phenylpyridinium (MPP), and its impact on key GIT and brain cells that contribute to the GBA.

Potential value of animal microphysiological systems.

Microphysiological systems (MPS) are designed to recapitulate aspects of tissue/organ physiology in vivo, thereby providing potential value in safety and efficacy assessments of FDA-regulated products and regulatory decision-making. While there have been significant advances in the development, use, and proposals of qualification criteria for human organ MPS, there remains a gap in the development using animal tissues. Animal MPS may be of value in many areas including the study of zoonotic diseases, assessment of the safety and efficacy of animal therapeutics, and possibly reduction of the use of animals in regulatory submissions for animal therapeutics.

Prevalence of Bronchodilator Responsiveness: A Comparison of Old Versus New Criteria.

Background: In 2021, the European Respiratory Society (ERS)/American Thoracic Society (ATS) guidelines issued a new definition of bronchodilator responsiveness, which is now defined as an increase in FEV or FVC by ≥ 10% of the predicted FEV or FVC. The impact of this revised definition on bronchodilator responsiveness prevalence has been relatively understudied.

Methods: We retrospectively analyzed data from 2,696 subjects who performed pulmonary function testing at the University of Iowa from 1997 to 2018.

Building Interprofessional Competencies Through a Collaborative Prescribing Activity With Osteopathic, Pharmacy, and Physician Assistant Students.

Introduction: Medication errors can lead to significant adverse events. Nearly 50% of medication errors occur during the prescription-writing stage of the medication use process, and effective interprofessional collaboration and communication are key to reducing error in this process.

Methods: We developed a three-part, 60-minute, interprofessional education activity providing medical, physician assistant, and pharmacy students the opportunity to practice collegial interprofessional communication surrounding prescribing practices.

Casimersen (AMONDYS 45™): An Antisense Oligonucleotide for Duchenne Muscular Dystrophy.

Casimersen (AMONDYS 45) is an antisense oligonucleotide of the phosphorodiamidate morpholino oligomer subclass developed by Sarepta therapeutics. It was approved by the Food and Drug Administration (FDA) in February 2021 to treat Duchenne muscular dystrophy (DMD) in patients whose gene mutation is amenable to exon 45 skipping. Administered intravenously, casimersen binds to the pre-mRNA of the gene to skip a mutated region of an exon, thereby producing an internally truncated yet functional dystrophin protein in DMD patients.

There is still limited information on the genomic structure and genetic diversity of African pigs. Genetic diversity studies can contribute significantly to the genetic improvement and conservation of African pigs. This study presents a genetic diversity analysis and population structure of pig breeds in Ghana, with a focus on the Ashanti Dwarf pig (ADP), an indigenous pig breed of Ghana.

Cascade of Multielectron Bubble Phases in Monolayer Graphene at High Landau Level Filling.

The phase diagram of an interacting two-dimensional electron system in a high magnetic field is enriched by the varying form of the effective Coulomb interaction, which depends strongly on the Landau level index. While the fractional quantum Hall states that dominate in the lower-energy Landau levels have been explored experimentally in a variety of two-dimensional systems, much less work has been done to explore electron solids owing to their subtle transport signatures and extreme sensitivity to disorder. Here, we use chemical potential measurements to map the phase diagram of electron solid states in N=2, N=3, and N=4 Landau levels in monolayer graphene.

Exposure to passive heat and cold stress differentially modulates cerebrovascular-CO responsiveness.

Heat and cold stress influence cerebral blood flow (CBF) regulatory factors (e.g., arterial CO partial pressure).

The Acute Effects of Theragun™ Percussive Therapy on Viscoelastic Tissue Dynamics and Hamstring Group Range of Motion.

Handheld percussive therapy (PT) massage guns have seen a rapid rise in use and with-it increased attention within injury prevention and sport performance settings. Early studies have proposed beneficial effects upon range of motion (ROM), however the mechanism behind these increases remains unreported. This study aimed to determine the influence of a minimal frequency PT dose upon ROM and myotonometry outcomes.

Current Noise of Hydrodynamic Electrons.

A resistor at finite temperature produces white noise fluctuations of the current called Johnson-Nyquist noise. Measuring the amplitude of this noise provides a powerful primary thermometry technique to access the electron temperature. In practical situations, however, one needs to generalize the Johnson-Nyquist theorem to handle spatially inhomogeneous temperature profiles.

Overnight declarative memory consolidation and non-rapid eye movement sleep electroencephalographic oscillations in older adults with obstructive sleep apnea.

Study Objectives: To compare overnight declarative memory consolidation and non-rapid eye movement (NREM) sleep electroencephalogram (EEG) oscillations in older adults with obstructive sleep apnea (OSA) to a control group and assess slow-wave activity (SWA) and sleep spindles as correlates of memory consolidation.

Methods: Forty-six older adults (24 without OSA and 22 with OSA) completed a word-pair associate's declarative memory task before and after polysomnography. Recall and recognition were expressed as a percentage of the morning relative to evening scores.

Menstrual phase influences cerebrovascular responsiveness in females but may not affect sex differences.

Sex differences in the rate and occurrence of cerebrovascular diseases (e.g., stroke) indicate a role for female sex hormones (i.

Challenging Neuromuscular Disease Cases.

The diagnosis of neuromuscular disorders requires a thorough history including family history and examination, with the next steps broadened now beyond electromyography and neuropathology to include genetic testing. The challenge in diagnosis can often be putting all the information together. With advances in genetic testing, some diagnoses that adult patients may have received as children deserve a second look and may result in diagnoses better defined or alternative diagnoses made.

Targeting workload to ameliorate risk of heat stress in industrial sugarcane workers.

Objective: The aim of this study was to quantify the physiological workload of manual laborers in industrial sugarcane and assess the effect of receiving a rest, shade, and hydration intervention to reduce heat stress exposure risk.

Methods: In an observational study, physiological workload was evaluated for burned cane cutters (BCC), seed cutters (SC) and drip irrigation repair workers (DIRW) using heart rate (HR) recorded continuously (Polar®) across a work shift. Workers' percentage of maximal HR (%HR), time spent in different HR zones, and estimated core temperature (ECTemp) were calculated.

Caring for COVID-19 patients through a pandemic in the intensive care setting: A narrative review.

Since the declaration of the novel SARS-CoV-2 virus pandemic, health systems/ health-care-workers globally have been overwhelmed by a vast number of COVID-19 related hospitalizations and intensive care unit (ICU) admissions. During the early stages of the pandemic, the lack of formalized evidence-based guidelines in all aspects of patient management was a significant challenge. Coupled with a lack of effective pharmacotherapies resulted in unsatisfactory outcomes in ICU patients.

Development of HEK-293 Cell Lines Constitutively Expressing Flaviviral Antigens for Use in Diagnostics.

Flaviviruses are important human pathogens worldwide. Diagnostic testing for these viruses is difficult because many of the pathogens require specialized biocontainment. To address this issue, we generated 39 virus-like particle (VLP)- and nonstructural protein 1 (NS1)-secreting stable cell lines in HEK-293 cells of 13 different flaviviruses, including dengue, yellow fever, Japanese encephalitis, West Nile, St.

Monoclonal antibodies to Cache Valley virus for serological diagnosis.

Cache Valley virus (CVV) is a mosquito-borne virus in the genus Orthobunyavirus, family Peribunyaviridae. It was first isolated from a Culiseta inorata mosquito in Cache Valley, Utah in 1956 and is known to circulate widely in the Americas. While only a handful of human cases have been reported since its discovery, it is the causative agent of fetal death and severe malformations in livestock.

Competing correlated states around the zero-field Wigner crystallization transition of electrons in two dimensions.

The competition between kinetic energy and Coulomb interactions in electronic systems leads to complex many-body ground states with competing orders. Here we present zinc oxide-based two-dimensional electron systems as a high-mobility system to study the low-temperature phases of strongly interacting electrons. An analysis of the electronic transport provides evidence for competing correlated metallic and insulating states with varying degrees of spin polarization.

Rapid microbial methanogenesis during CO storage in hydrocarbon reservoirs.

Carbon capture and storage (CCS) is a key technology to mitigate the environmental impact of carbon dioxide (CO) emissions. An understanding of the potential trapping and storage mechanisms is required to provide confidence in safe and secure CO geological sequestration. Depleted hydrocarbon reservoirs have substantial CO storage potential,, and numerous hydrocarbon reservoirs have undergone CO injection as a means of enhanced oil recovery (CO-EOR), providing an opportunity to evaluate the (bio)geochemical behaviour of injected carbon.

Electronic thermal transport measurement in low-dimensional materials with graphene non-local noise thermometry.

In low-dimensional systems, the combination of reduced dimensionality, strong interactions and topology has led to a growing number of many-body quantum phenomena. Thermal transport, which is sensitive to all energy-carrying degrees of freedom, provides a discriminating probe of emergent excitations in quantum materials and devices. However, thermal transport measurements in low dimensions are dominated by the phonon contribution of the lattice, requiring an experimental approach to isolate the electronic thermal conductance.
