Journal Articles: Epidemiology

Although microbial populations in the gut microbiome are associated with COVID-19 severity, a causal impact on patient health has not been established. Here we provide evidence that gut microbiome dysbiosis is associated with translocation of bacteria into the blood during COVID-19, causing life-threatening secondary infections. We first demonstrate SARS-CoV-2 infection induces gut microbiome dysbiosis in mice, which correlated with alterations to Paneth cells and goblet cells, and markers of barrier permeability. Samples collected from 96 COVID-19 patients at two different clinical sites also revealed substantial gut microbiome dysbiosis, including blooms of opportunistic pathogenic bacterial genera known to include antimicrobial-resistant species. …

Modelling Air Quality In An Aircraft Passenger Cabin Using Health Care Standards, Bert Silich

International Journal of Aviation, Aeronautics, and Aerospace

The interest in aerosol contamination of aircraft passenger cabins has increased since the onset of the COVID-19 pandemic. Mathematical models have been developed to help describe how an aerosol behaves in a closed space. The number of infectious particles inhaled is of scientific interest because it can be related to the risk of getting ill from a pathogen. The data required to calculate these results is often difficult to obtain in real world settings. In fact, particle inhalation details are not obtained in the day-to-day routine of a health care environment and are they not required to maintain safety. Hospital …

Stroboscopic Augmented Reality As An Approach To Mitigate Gravitational Transition Effects During Interplanetary Spaceflight, Ethan Waisberg, Joshua Ong, Nasif Zaman, Sharif Amit Kamran, Andrew G. Lee, Alireza Tavakkoli

International Journal of Aviation, Aeronautics, and Aerospace

During interplanetary spaceflight, periods of extreme gravitational transitions will occur such as transitions between hypergravity, hypogravity, and microgravity. Following gravitational transitions, rapid sensorimotor adaptation or maladaptation may occur which can affect gaze control and weaken dynamic visual acuity in astronauts. A reduction in dynamic visual acuity during spaceflight could possibly impact or impair mission critical activities (e.g., control of extraterrestrial machinery/vehicles and other important tasks). Stroboscopic visual training is an emerging visual tool that has been terrestrially observed to enhance visual performance and perception by performing tasks under conditions of intermittent vision. This technique has also been seen to increase …

The Combinatory Effects Of Pediatric Obesity And Ontogeny On Monocarboxylate Transporter Expression In Tissues Of Drug Disposition, Michael Ng Jan 2022

The Combinatory Effects Of Pediatric Obesity And Ontogeny On Monocarboxylate Transporter Expression In Tissues Of Drug Disposition, Michael Ng

University of the Pacific Theses and Dissertations

Proton-coupled and sodium-dependent monocarboxylate transporters are encoded by the SLC16A and SLC5A gene family of solute carriers, and are responsible for the transport of essential nutrients such as L-lactate, pyruvate, and ketone bodies. Basigin, or CD147, acts as an ancillary protein for MCT1 and MCT4, and is involved in membrane surface expression of transporters. MCT's are also involved in the shuttling of monocarboxylic xenobiotics across cell membranes, including the drugs valproate and gamma hydroxybutyrate. MCT’s are also important for normal mammalian development, particularly during embryogenesis and early neonatal life. Previous studies have shown that ketogenic diets increase MCT expression in …

Effect Of Rapeseed Inclusion In Late-Summer Planted Oat Pasture On Growing Performance Of Beef Steers, Devin A. Jakub, Hannah E. Riley, Kristin E. Hales, Steven D. Shackelford, Harvey C. Freetly, M. E. Drewnoski

Nebraska Beef Cattle Reports

An oat monoculture was planted in late summer at 100 lb/ac and compared to oats planted at 50 lb/ac with rapeseed included at 3 lb/ac. Seed cost of the oat monoculture ($20/ac) was greater than the mix ($15/ac). Initial forage yield was not affected by the inclusion of rapeseed with fall oat. Calf gain was significantly greater and cost of gain was significantly decreased when rapeseed was included due to the combination of greater gains and lesser seed cost. Including rapeseed in late summer planted oats may be beneficial for producers who want to graze growing calves in the fall.

Titania Nanosheets Induce Anticancer Activityin Human Non-Small Cell Lung Cancer Cells, Rapeepun Soonnarong

Chulalongkorn University Theses and Dissertations (Chula ETD)

Metal nanomaterials can enhance the efficacy of current cancer therapies. Here, we show that Ti0.8O2 nanosheets cause cytotoxicity in several lung cancer cells but not in normal cells. The nanosheet-treated cells showed certain apoptosis characteristics. Protein analysis further indicated the activation of the p53-dependent death mechanism. Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) analyses revealed the cellular uptake of the nanosheets and the induction of cell morphological change. Ti0.8O2 nanosheets induce apoptosis through a molecular mechanism involving peroxynitrite (ONOO−) generation. As peroxynitrite is known to be a potent inducer of S-nitrosylation, we further found that the nanosheets mediated …
