Manuka Honey Reduces The Virulence Of Pectobacterium Brasiliense By Suppressing Genes That Encode Plant Cell Wall-Degrading Enzymes, Ava Sheila, Subandiyah Siti, Rohman Muhammad Saifur, Ogawa Naoto, Joko Tri

ASEAN Journal on Science and Technology for Development

The primary virulence of soft rot pectobacteria, including Pectobacterium brasiliense, is mainly determined by the massive production of plant cell wall-degrading enzymes (PCWDEs), which promote plant tissue maceration in many crops. The antibiotic treatment to treat bacterial soft rot causes environmental problems and potentially affects resistance. Antibiotic resistance is driving interest in antimicrobial treatments, and no organism has been reported to have acquired resistance to honey. However, the use of honey as a therapeutic agent for plant bacterial pathogens has rarely been studied. Therefore, this study was undertaken to determine the in vitro effect of Manuka honey against P. brasiliense …

Mechanical And Thermal Load Effect On Piston Crown Of A Biogas Engine: A Simulation Approach, Truc Nguyen The, Anh Duc Tran, Cam Van Nguyen, Khac Tung Nguyen, Dinh Long Hoang, Xuan Phong Trinh, Nguyen Duc Khanh

ASEAN Journal on Science and Technology for Development

This paper presents the study results on stress and deformation of the piston crown of a biogas engine converted from a conventional diesel engine using dedicated software. The original diesel engine was modified to reduce the compression ratio to suit biogas fuel. The original engine's combustion chamber and compression ratio were changed by modifying the piston crown to a heron type. The parameters of in-cylinder pressure and temperature were determined by the thermodynamic simulation software AVL Boost. Research results show that the in-cylinder pressure decreased compared to diesel when using biogas fuel, but the temperature increased. The infinite element method-based …

A Systematic Review Of The Effects Of Meditative And Mindful Walking On Mental And Cardiovascular Health, Dustin W. Davis, Bryson Carrier, Kyle Cruz, Brenna Barrios, Merrill Russen Landers, James W. Navalta

International Journal of Exercise Science

International Journal of Exercise Science 15(2): 1692-1734, 2022. Meditative and mindful exercise are types of physical exercise during which people pay attention, on purpose, to each new present moment without judging their experience. The goal is to apply an accepting awareness of the environment, bodily sensations, thoughts, and emotions without labeling them (e.g., good or bad). The literature centers on qigong, tai chi, and yoga, which are types of mindful exercise that improve mental and cardiovascular health. It is unclear if meditative and mindful walking also improve these health domains. To the authors’ knowledge, this question has not been addressed …

Faculty, Staff and Student Publications

Recent genome wide association studies have identified 89 common genetic variants robustly associated with ischemic stroke and primarily located in non-coding regions. To evaluate the contribution of coding variants, which are mostly rare, we performed an exome array analysis on 106,101 SNPs for 9721 ischemic stroke cases from the SiGN Consortium, and 12,345 subjects with no history of stroke from the Health Retirement Study and SiGN consortium. We identified 15 coding variants significantly associated with all ischemic stroke at array-wide threshold (i.e., p < 4.7 × 10-7), including two common SNPs in ABO that have previously been associated with stroke. Twelve of the remaining 13 variants were extremely rare …

New Semi-Dwarfing Alleles With Increased Coleoptile Length By Gene Editing Of Gibberellin 3-Oxidase 1 Using Crispr-Cas9 In Barley (Hordeum Vulgare L.), Jingye Cheng, Camilla Hill, Yong Han, Tianhua He, Xingguo Ye, Sergey Shabala, Ganggang Guo, Meixue Zhou, Ke Wang, Chengdao Li

Grain and Other Field Crops Research Articles

The green revolution was based on genetic modification of the gibberellin (GA) hormone system with “dwarfing” gene mutations that reduces GA signals, conferring shorter stature, thus enabling plant adaptation to modern farming conditions. Strong GA-related mutants with shorter stature often have reduced coleoptile length, discounting yield gain due to their unsatisfactory seedling emergence under drought conditions. Here we present gibberellin (GA) 3-oxidase1 (GA3ox1) as an alternative semi-dwarfing gene in barley that combines an optimal reduction in plant height without restricting coleoptile and seedling growth. Using large-scale field trials with an extensive collection of barley accessions, we showed that a natural …

Glutamine Produces Ammonium To Tune Lysosomal Ph And Regulate Lysosomal Function, Jian Xiong, Thi Thu Trang Luu, Kartik Venkatachalam, Guangwei Du, Michael X Zhu

Faculty, Staff and Student Publications

Glutamine is one of the most abundant amino acids in the cell. In mitochondria, glutaminases 1 and 2 (GLS1/2) hydrolyze glutamine to glutamate, which serves as the precursor of multiple metabolites. Here, we show that ammonium generated during GLS1/2-mediated glutaminolysis regulates lysosomal pH and in turn lysosomal degradation. In primary human skin fibroblasts BJ cells and mouse embryonic fibroblasts, deprivation of total amino acids for 1 h increased lysosomal degradation capacity as shown by the increased turnover of lipidated microtubule-associated proteins 1A/1B light chain 3B (LC3-II), several autophagic receptors, and endocytosed DQ-BSA. Removal of glutamine but not any other amino …

Venn, Evan Schroder, Nick Y. Palermo, Mohammad Alshabeeb, Benson J. Edagwa, Jason J. Payne, Keshoer R. Bidasee

Department of Biochemistry: Faculty Publications

The incidence of sudden cardiac death (SCD) in people living with HIV infection (PLWH), especially those with inadequate viral suppression, is high and the reasons for this remain incompletely characterized. The timely opening and closing of type 2 ryanodine receptor (RyR2) is critical for ensuring rhythmic cardiac contraction–relaxation cycles, and the disruption of these processes can elicit Ca²⁺ waves, ventricular arrhythmias, and SCD. Herein, we show that the HIV protein Tat (HIVTat: 0–52 ng/mL) and therapeutic levels of the antiretroviral drugs atazanavir (ATV: 0–25,344 ng/mL), efavirenz (EFV: 0–11,376 ng/mL), and ritonavir (RTV: 0–25,956 ng/mL) bind to and modulate the …

Deciphering The Role Of Rna Structure In Translation Efficiency., Jianan Lin, Yang Chen, Yuping Zhang, Haifan Lin, Zhengqing Ouyang

Faculty Research 2022

BACKGROUND: RNA secondary structure has broad impact on the fate of RNA metabolism. The reduced stability of secondary structures near the translation initiation site/start codon of the coding region promotes the efficiency of translation in both prokaryotic and eukaryotic species. However, the inaccuracy of in silico folding and the focus on the coding region limit our understanding of the global relationship between the whole mRNA structure and translation efficiency. Leveraging high-throughput RNA structure probing data in the transcriptome, we aim to systematically investigate the role of RNA structure in regulating translation efficiency.

RESULTS: Here, we analyze the influences of hundreds …

The Stockholm Paradigm Explains The Dynamics Of Darwin’S Entangled Bank, Including Emerging Infectious Disease, Salvatore J. Agosta

MANTER: Journal of Parasite Biodiversity

Pathogens and their hosts are embedded within the larger biosphere, what Darwin called the “entangled bank.” Emerging infectious disease occurs when a parasite “switches” to a new host. Understanding the dynamics of emerging disease requires understanding the dynamics of host-switching, which requires a more general understanding of how the biosphere and its constituent members cope when conditions change. The Stockholm paradigm is an integrative evolutionary framework that describes how living systems cope with change by oscillating between exploiting and exploring the geographical and functional dimensions of their environments. It combines organismal capacity, ecological opportunity, and the repeated external perturbations to …

Accurate prediction of the phenotypic outcomes produced by different combinations of genotypes, environments, and management interventions remains a key goal in biology with direct applications to agriculture, research, and conservation. The past decades have seen an expansion of new methods applied toward this goal. Here we predict maize yield using deep neural networks, compare the efficacy of 2 model development methods, and contextualize model performance using conventional linear and machine learning models. We examine the usefulness of incorporating interactions between disparate data types. We find deep learning and best linear unbiased predictor (BLUP) models with interactions had the best overall …

Niche Modeling Of Eight Crayfish Species In Texas, Nathan Schubert

Biology Theses

Freshwater species make up ~10% of all known species and occupy less than one percent of earth’s habitat, which is being degraded by human usage. Crayfish have a large impact on their aquatic or terrestrial environment and can serve as a health indicator of aquatic environments, as they generally require undegraded environments. In many habitats, crayfish make up more than half of the macroinvertebrate biomass, and play important ecological roles, as a food resource for both aquatic and terrestrial species, as predators of fish and invertebrates, and as bioprocessors of vegetation and detritus. The objective of this project was to …

A Tree-Ring Record Of Historical Fire Activity In A Piedmont Longleaf Pine (Pinus Palustris Mill.) Woodland In North Carolina, Usa, Monica T. Rother, Thomas W. Patterson, Paul A. Knapp, Tyler J. Mitchell, Nell Allen

Faculty Publications

CO₂ capture from industrial point source waste streams represents an important need for achieving the global goal of carbon-neutrality. Compared with conventional liquid sorbents, solid sorbents can exhibit several distinct advantages, including enhanced lifetime and reduced energy consumption for sorbent regeneration. Considering that reducing CO₂ emission is a great challenge, reaching approximately 37 billion metric tons just in 2021, ideal sorbent solutions should not only exhibit a high capture performance but also enable large scale manufacturing using low-cost precursors and simple processes. In this work, we demonstrate the use of a commodity polymer, polystyrene-block-polyisoprene-block-polystyrene …

Heat Stressed Exercise Elicits Shifts In Cooling Strategies Across Body Mass In Tropical Songbirds, Kristen Dee Oliver

Biology ETDs

In resting animals, water use positively correlates with metabolic rate, for example smaller animals using proportionally more water per gram of body mass. However, animals also must endure heat and exertion, and evaporative cooling requires additional water use that may not scale similarly with body size. How evaporative water loss allometrically scales with body mass during heat-stressed exercise is poorly resolved, particularly for birds, yet is critically important for understanding the consequences of climate warming on the fitness of bird populations. Here, we evaluated how air temperature (T_a) influenced evaporative water loss during exercise (EWL_exercise) across …

The Acute Effects Of Talocrural Mwm Compared With The Application Of Soft-Tissue Of The Plantarfascia On Chronic Lateral Ankle Sprains For Ankle Dorsiflexion R.O.M., Peter Hempenstall, Brian O'Rourke

SURE Journal: Science Undergraduate Research Experience Journal

Previous research has looked at various treatment remedies for improving acute ankle Dorsiflexion Range of Motion (DFROM) post chronic Lateral Ankle Sprain (LAS). Mulligan’s Mobilisation with Movement (MWM) appears frequently however, the significance and mechanism remain quite conflicting (Gilbreath et al., 2015). It is also known that after a LAS, the Lateral Ligament Complex (LLC) is compromised and the calcaneus inverts, increasing stiffness of plantarfascia (Al-Mohrej & Al-Kenani, 2016, Denegar et al., 2002, Loudon & Bell, 1996). The objective of this study was to further explore the effectiveness of MWM compared with soft-tissue (ST) application of the plantarfascia on acute …

Therapies For Mitochondrial Disorders, Kayli Sousa Smyth, Anne Mulvihill

SURE Journal: Science Undergraduate Research Experience Journal

Mitochondria are cytoplasmic, double-membrane organelles that synthesise adenosine triphosphate (ATP). Mitochondria contain their own genome, mitochondrial DNA (mtDNA), which is maternally inherited from the oocyte. Mitochondrial proteins are encoded by either nuclear DNA (nDNA) or mtDNA, and both code for proteins forming the mitochondrial oxidative phosphorylation (OXPHOS) complexes of the respiratory chain. These complexes form a chain that allows the passage of electrons down the electron transport chain (ETC) through a proton motive force, creating ATP from adenosine diphosphate (ADP). This study aims to explore current and prospective therapies for mitochondrial disorders (MTDS). MTDS are clinical syndromes coupled with abnormalities …

Anthelmintic Resistance In Sheep Across Ireland And The Uk: A Literature Review Of The In Vivo Versus In Vitro Methods, Megan Tumulty

SURE Journal: Science Undergraduate Research Experience Journal

Background: The animal welfare and production consequences of gastrointestinal nematode infections, namely Nematodirus battus, on sheep are compelling. The control of gastrointestinal infections has been heavily reliant on the administration of anthelmintics since their introduction into mainstream use in 1960. However, their frequent and often excessive use has resulted in anthelmintic resistance being reported extensively in several gastrointestinal nematode species. The prevalence of anthelmintic resistance as well as the increase in the number of cases of multiple-drug resistance in nematode populations now poses substantial hindrance on the viability of sheep production systems. However, despite the threat N. battus poses …

The Role Of Dha In The Impact Of Trem2 On Microglia Activation And Alzheimer’S Disease, Michael A. Palmieri Iii

Seton Hall University Dissertations and Theses (ETDs)

Alzheimer’s disease (AD) is a neurological disease that is associated with microglia activation. An important receptor involved in microglia activation is Triggering receptor expressed on myeloid cells 2 (TREM2). Recent studies suggest that docosahexaenoic acid (DHA) could reduce the neuroinflammation that is associated with microglia activation. We hypothesized that when DHA concentration was increased, TREM2 expression would decrease, microglia activity would be inhibited, and a resulting decrease in neuroinflammation would be observed. We examined peer-reviewed journal articles from 2017-2022 that investigated the relationship between TREM2 activation and severity of AD symptoms, the protective properties of DHA against AD, and the …
