We study a novel multi-strain SIR epidemic model with selective immunity by vaccination. A newer strain is made to emerge in the population when preexisting has reached equilbrium. assume that this does not exhibit cross-immunity original strain, hence those who are vaccinated and recovered from become susceptible strain. Recent events involving COVID-19 virus shows it possible for viral at time influenza virus, well-known vaccine readily available, active population. solved four different...
Despite the potential to increase soil organic matter, cycle nutrients, and suppress weeds, there is a concern that cover crops (CCs) water use negatively impacts subsequent in water-limited environments. Cover crop management practices such as planting termination timing may mitigate detrimental of CCs semi-arid cropping systems. To determine effects under environments, we evaluated total CC biomass produced fall spring, content during maize growing season, weed density biomass, residue,...

Maintaining proper hand hygiene is crucial in preventing the spread of infections and other communicable diseases. It imperative to determine factors that affect likelihood initiating maintaining recommended handwashing behavior, especially during a pandemic. This quantitative, secondary study employed latent profile analysis (LPA) identify different attitudes toward behavior change based on Multi-Theory Model (MTM) framework context following guidelines provided by Centers for Disease...
Background/Objective : Relative proportion of cases in a multi-strain pandemic like the COVID-19 provides insight on how fast newly emergent variant dominates infected population. However, behavior relative emerging variants is an understudied field. We investigated dominant using nonlinear statistical methods and calculated time to dominance each variant. Method used phenomenological approach model national- regional-level share data from national genomic surveillance system provided by...
The Philippines' primary care is delivered via local health centers called barangay (BHCs). Barangays are the most government units in Philippines. Designed to promote and prevent disease basic care, these BHCs staffed mainly by workers (BHWs). However, there has been limited research on social environmental factors affecting underserved communities' access areas of Given importance prevention promotion, it necessary identify obstacles providing their services initiatives.This study aimed...

Human mesenchymal stem cells (hMSCs) are primary with high clinical relevance that could be enhanced through genetic modification. However, gene delivery, particularly nonviral routes, is inefficient. To address the shortcomings of delivery to hMSCs, our lab has previously demonstrated pharmacological "priming" hMSCs clinically approved drugs can increase transfection in by modulating transfection-induced cytotoxicity. even priming, hMSC remains inefficient for applications. This work takes...
Background: Breastfeeding provides several positive health benefits for the newborn child, yet breastfeeding rates remain low in United States (US). Theory-based approaches have potential to improve promotion interventions. Hence, study examined correlates of intention breastfeed among US pregnant women based on multi-theory model (MTM) behavior change. Methods: Using a cross-sectional design, 36-item online survey was administered nationally representative sample 315 US. The instrument...
A significant proportion of frontline nurses developed post-traumatic stress disorder (PTSD) symptoms as a result working during the COVID-19 pandemic. This study aimed to determine efficacy mindfulness- and acceptance-based smartphone app intervention among traumatized by was two-arm, randomized controlled trial. We randomly assigned 60 in various clinical settings United States pandemic either group (i.e. participants used mindfulness for 6 wk) or wait-list control group. assessed app's...
Latino children in the United States (US) have a higher prevalence of overweight/obesity compared to white children. Previous studies suggest that acculturation US is associated with health behaviors such as diet, body mass index (BMI), and physical activity. However, role parental remains understudied, particularly use validated measures.
Abstract Aim Emerging evidence suggests that poor sleep (i.e., lack of and low quality) significantly impacts the risk severe cognitive impairment. However, research on use quality metrics as early predictors impairment remains scarce. In this study, we investigated association between objective measures plasma levels Eotaxin-1, an biomarker for impairment, among nurses. Methods We used data from 35 nurses who underwent multiple home studies with electroencephalograms workdays days off were...
Many Asian immigrants, including Filipino Americans (FilAms), experience psychological distress (PD) due to the challenges in adjusting their new country and culture. This descriptive comparative study aimed compare FilAms Filipinos concerning levels of PD, sources stress, use health-promotion strategies.Data from 89 95 living urban cities, obtained I-HELP-FILIPINOS database, measuring cardiometabolic risks, mental health, environmental stressors 2017, were examined.The mean age all...
We studied the effect of transmissibility and vaccination on time required for an emerging strain existing virus to dominate in infected population using a simulation-based experiment. The emergent is assumed be completely resistant available vaccine. A stochastic version modified SIR model viral strains was developed simulate surveillance data infections. proportion infections among modeled logistic curve dominance (TTD) recorded each simulation. factorial experiment implemented compare TTD...
<b><sc>Abstract.</sc></b> Emissions of carbon dioxide, methane, and nitrous oxide – potent greenhouse gases - from stored beef feedlot manure are a significant concern relative to climate change. Research on methane reduction strategies for enteric emissions has identified the application organic additives, such as bromoform linseed oil, ruminant diets potential solutions reducing pathogenic bacteria in excreted manure. The objective this study was determine effect oil gas manure, E. coli...
