Nanoparticles As Antibiotic-Delivery Vehicles (Advs) Overcome Resistance By Mrsa And Other Mdr Bacterial Pathogens: The Grenade Hypothesis, Amjed Alabresm, Yung Pin Chen, Savannah Wichter-Chandler, Jamie Lead, Brian C. Benicewicz

Faculty Publications

Objectives

The aim of this study was to examine how the concentrated delivery of less effective antibiotics, such as the Β-lactam penicillin G, by linkage to nanoparticles (NPs), could influence the killing efficiency against various pathogenic bacteria, including methicillin-resistant Staphylococcus aureus (MRSA) and other multidrug resistant (MDR) strains.

Methods

The Β-lactam antibiotic penicillin G (PenG) was passively sorbed to fluorescent polystyrene NPs (20 nm) that were surface-functionalized with carboxylic acid (COO⁻-NPs) or sulfate groups (SO₄⁻-NPs) to form a PenG-NP complex. Antimicrobial activities of PenG-NPs were evaluated against Gram-negative and Gram-positive bacteria, including antibiotic resistant strains. …

A Method To Measure The Partitioning Coefficient Of Volatile Organic Compounds In Nanoparticles, Guiying Rao, Jeonghyeon Ahn, Abigail Evans, Michelle Casey, Eric P. Vejerano

Faculty Publications

The partitioning behavior of volatile organic compounds (VOCs) into nanoparticles is less studied compared to those of semivolatile organic compounds (SVOCs) because of the lower concentration of the VOCs that is expected to partition into particles. One challenge in measuring the accurate partition coefficient of VOCs is quantifying their low mass fraction that sorbed on nanoparticles and differentiating them from the high VOC concentrations present in the gas-phase. Systematically characterizing the partitioning coefficient at a specific environmental condition is also difficult when sampling in the field. During field sampling, thermal and non-thermal issues such as sampling artifacts and non-equilibrium conditions …

Men’S Vasectomy Knowledge, Attitudes, And Information-Seeking Behaviors In The Southern United States: Results From An Exploratory Survey, Ashley L. White, Rachel E. Davis, Deborah Lynn Billings Phd, Emily S. Mann

Faculty Publications

Vasectomy is one of the few options men have to manage their reproductive capacity and take on a more equitable role in pregnancy prevention. While the method is underused throughout the United States, the southern states have a lower prevalence rate compared to the rest of the country. Existing survey research does not assess what men know or think about the procedure as a means of understanding why this is the case. We created and conducted an exploratory survey to assess men’s knowledge, attitudes, and information-seeking behaviors about vasectomy in the Southern United States. We used targeted Facebook advertising to …

A Letter To Reconsider The Conditions For Testing Decontaminated N95 Respirators For Emergency Reuse To Address Shortage, Eric P. Vejerano, Jeonghyeon Ahn

Faculty Publications

The battle with COVID-19 pandemic has resulted in the shortage of personal protective equipment, particularly, N95 respirators. Healthcare workers who reused N95 respirators may resort to unproven methods of cleaning/sterilization that can severely compromise the respirators’ filtration efficiency. A recently issued guideline will test decontaminated N95 respirators against particles with a median diameter of 0.075 ± 0.020 µm at a flow rate of 85 L min–1. For emergency reuse, these conditions may be too stringent. N95 respirators tested at this flow rate had predicted efficiencies of < 69%, assuming complete degradation of their electrostatic coating. Experimental efficiencies were ~15% lower. For emergency reuse, we recommend to either adjust the flow rate closer to normal breathing, or the size of the test particle should reflect that of virus-laden respiratory aerosols (~> 0.5 µm). By reconsidering the test conditions, a substantial fraction of used/decontaminated respirators can …

Can Children Catch Up From The Consequences Of Undernourishment? Evidence From Child Linear Growth, Developmental Epigenetics, And Brain And Neurocognitive Development, Jef L. Leroy, Edward A. Frongillo Jr., Pragya Dewan, Maureen M. Black, Robert A. Waterland

Faculty Publications

Recovery from nutritionally induced height deficits continues to garner attention. The current literature on catch-up growth, however, has 2 important limitations: wide-ranging definitions of catch-up growth are used, and it remains unclear whether children can recover from the broader consequences of undernutrition. We addressed these shortcomings by reviewing the literature on the criteria for catch-up in linear growth and on the potential to recover from undernutrition early in life in 3 domains: linear growth, developmental epigenetics, and child brain and neurocognitive development. Four criteria must be met to demonstrate catch-up growth in height: after a period in which a growth-inhibiting …

Nutrient Timing: A Garage Door Of Opportunity?, Shawn M. Arent, Harry P. Cintineo, Bridget A. Mcfadden, Alexa Jenny Chandler, Michelle Angelique Arent

Faculty Publications

Nutrient timing involves manipulation of nutrient consumption at specific times in and around exercise bouts in an effort to improve performance, recovery, and adaptation. Its historical perspective centered on ingestion during exercise and grew to include pre- and post-training periods. As research continued, translational focus remained primarily on the impact and outcomes related to nutrient consumption during one specific time period to the exclusion of all others. Additionally, there seemed to be increasing emphasis on outcomes related to hypertrophy and strength at the expense of other potentially more impactful performance measures. As consumption of nutrients does not occur at only …

Differential Relationships Between Waist Circumference And Cardiorespiratory Fitness Among People With And Without Type 2 Diabetes, Andrew Ortaglia, Samantha M. Mcdonald, Christina Supino, Michael D. Wirth, Xuem Sui, Matteo Bottai

Faculty Publications

Adults with type 2 diabetes mellitus tend to exhibit an increased level of central adiposity, augmenting their risk of further non-communicable diseases (NCDs). Importantly, consistent evidence demonstrates a significant, negative association between cardiorespiratory fitness (CRF) and waist circumference (WC). However, no previous studies have investigated differences in these CRF-related reductions in WC between adults with and without diabetes.

This study used data from the Aerobic Center for Longitudinal Studies, conducted between 1970 and 2006 among predominately Non-Hispanic White, middle-to-upper class adults in Texas. Quantile regression models were used to estimate CRF-related differences in WC between persons with and without diabetes. …

Rethinking Covid-19 Vulnerability: A Call For Lgbtq+ Im/Migrant Health Equity In The U.S. During And After A Pandemic, Nolan Kline

Faculty Publications

Public health responses to the COVID-19 pandemic have emphasized older adults’ vulnerability, but this obfuscates the social and political root causes of health inequity. To advance health equity during a novel communicable disease outbreak, public health practitioners must continue to be attentive to social and political circumstances that inform poor health. Such efforts are especially needed for populations who are exposed to numerous social and political factors that structure health inequity, such as lesbian, gay, bisexual, transgender, or otherwise-queer identifying (LGBTQ+) populations and im/migrant populations. The COVID-19 outbreak is therefore a critical time to emphasize root causes of health inequity.

Chemotherapy is a mainstay of treatment for solid tumors. However, little is known about how therapy-induced immune cell infiltration may affect therapy response. We found substantial CD45 immune cell density adjacent to E-selectin expressing inflamed vessels in doxorubicin (DOX)-treated residual human breast tumors. While CD45 level was significantly elevated in DOX-treated wildtype mice, it remained unchanged in DOX-treated tumors from E-selectin null mice. Similarly, intravenous administration of anti-E-selectin aptamer (ESTA) resulted in a significant reduction in CD45 immune cell density in DOX-treated residual tumors, which coincided with a delay in tumor growth and lung metastasis in MMTV-pyMT mice. Additionally, both …
