Bondonno

Research outputs 2022 to 2026

Dietary nitrate, found predominantly in green leafy vegetables and other vegetables such as radish, celery, and beetroot, has been shown to beneficially modulate inflammatory processes and immune cell function in animals and healthy individuals. The impact of increased nitrate intake on soluble inflammatory mediators in individuals with hypertension is unclear. We assessed whether the daily consumption of dietary nitrate via beetroot juice for 1-week lowered levels of circulating inflammatory markers in men and women with treated hypertension. Twenty-seven male and female participants were recruited to a randomized, placebo-controlled, double-blind crossover trial. The effects of 1-week intake of nitrate-rich beetroot juice …

In a published randomized controlled trial, household units were randomized to a nutrient bar supplementation group or a control condition, but the non-independence of observations within the same household (i.e., the clustering effect) was not accounted for in the statistical analyses. Therefore, we reanalyzed the data appropriately by adjusting degrees of freedom using the between-within method, and accounting for household units using linear mixed effect models with random intercepts for family units and subjects nested within family units for each reported outcome. Results from this reanalysis showed that ignoring the clustering and nesting effects in the original analyses had resulted …

Eating Disorders In Men: A Comprehensive Summary, Connor James Spratt, Liam Alexander Mackenzie Myles, Emanuele Maria Merlo

Journal of Mind and Medical Sciences

Eating disorders (EDs) have detrimental effects on an individual’s physical and mental health, along with significant interpersonal, social and economic effects. Furthermore, men who are suffering with an ED face unique challenges with this. Men suffering with EDs have historically received little attention within ED research, diagnosis and intervention. However, the number of men suffering with these issues is significant and growing. Understanding of EDs tend to ignore male experiences, meaning many are left to suffer in silence until the ED has developed to a critical point. However, many now recognize the need to understand the issues facing men suffering …

Background: Pro-opiomelanocortin (POMC) neurons play a sexually dimorphic role in body weight and glucose balance. However, the mechanisms for the sex differences in POMC neuron functions are not fully understood.

Results: We detected small conductance calcium-activated potassium (SK) current in POMC neurons. Secondary analysis of published single-cell RNA-Seq data showed that POMC neurons abundantly express SK3, one SK channel subunit. To test whether SK3 in POMC neurons regulates POMC neuron functions on energy and glucose homeostasis, we used a Cre-loxP strategy to delete SK3 specifically from mature POMC neurons. POMC-specific deletion of SK3 did not affect body weight in either …

Biogenesis And Regulatory Roles Of Circular Rnas, Li Yang, Jeremy E Wilusz, Ling-Ling Chen

Children’s Nutrition Research Center Staff Publications

Covalently closed, single-stranded circular RNAs can be produced from viral RNA genomes as well as from the processing of cellular housekeeping noncoding RNAs and precursor messenger RNAs. Recent transcriptomic studies have surprisingly uncovered that many protein-coding genes can be subjected to backsplicing, leading to widespread expression of a specific type of circular RNAs (circRNAs) in eukaryotic cells. Here, we discuss experimental strategies used to discover and characterize diverse circRNAs at both the genome and individual gene scales. We further highlight the current understanding of how circRNAs are generated and how the mature transcripts function. Some circRNAs act as noncoding RNAs …

In mammals, trait variation is often reported to be greater among males than females. However, to date, mainly only morphological traits have been studied. Energy expenditure represents the metabolic costs of multiple physical, physiological, and behavioral traits. Energy expenditure could exhibit particularly high greater male variation through a cumulative effect if those traits mostly exhibit greater male variation, or a lack of greater male variation if many of them do not. Sex differences in energy expenditure variation have been little explored. We analyzed a large database on energy expenditure in adult humans (1494 males and 3108 females) to investigate whether …

Background: In medical genetics, discovery and characterization of disease trait contributory genes and alleles depends on genetic reasoning, study design, and patient ascertainment; we suggest a segmental haploid genetics approach to enhance gene discovery and molecular diagnostics.

Methods: We constructed a genome-wide map for nonallelic homologous recombination (NAHR)-mediated recurrent genomic deletions and used this map to estimate population frequencies of NAHR deletions based on large-scale population cohorts and region-specific studies. We calculated recessive disease carrier burden using high-quality pathogenic or likely pathogenic variants from ClinVar and gnomAD. We developed a NIRD (NAHR deletion Impact to Recessive Disease) score for recessive …

Study Protocol For An Adapted Personal Project Analysis To Measure Vertical Inter-Goal Relations On Physical Activity And Diet, Sara Kassas, Catherine Culot, Geert Crombez, Annique Smeding, Christophe Leys, Debbe Thompson, Ann Desmet

Children’s Nutrition Research Center Staff Publications

Background: The promotion of multiple healthy lifestyles has been implemented as part of public health efforts to prevent and reduce the burden of non-communicable diseases. However, these interventions have shown a heterogeneity in their effectiveness. The pursuit of multiple daily goals may influence overall progress in achieving health goals. Horizontal inter-goal relations can be conflicting (due to time constraints) or facilitating (due to goal compatibility) and impact progress towards goal achievement. Personal values also play an important role in health promotion. Personal values direct attention towards accomplishing a higher-level goal through goal setting. Identifying the conflicting or facilitating relationships between …

Mochi: A Comprehensive Cross-Platform Tool For Amplicon-Based Microbiota Analysis, Jun-Jie Zheng, Po-Wen Wang, Tzu-Wen Huang, Yao-Jong Yang, Hua-Sheng Chiu, Pavel Sumazin, Ting-Wen Chen

Children’s Nutrition Research Center Staff Publications

Motivation: Microbiota analyses have important implications for health and science. These analyses make use of 16S/18S rRNA gene sequencing to identify taxa and predict species diversity. However, most available tools for analyzing microbiota data require adept programming skills and in-depth statistical knowledge for proper implementation. While long-read amplicon sequencing can lead to more accurate taxa predictions and is quickly becoming more common, practitioners have no easily accessible tools with which to perform their analyses.

Results: We present MOCHI, a GUI tool for microbiota amplicon sequencing analysis. MOCHI preprocesses sequences, assigns taxonomy, identifies different abundant species and predicts species diversity and …

How Did The Dietary Habits Of Patients With Chronic Medical Conditions Change During Covid-19?, Sahil K. Patel, Adarsh Gupta

Rowan-Virtua School of Osteopathic Medicine Departmental Research

CONTEXT: Previous studies have examined the changes in the dietary habits of general populations during the COVID-19 pandemic but have not focused on specific populations such as those with chronic medical conditions (CMCs). Prior to major vaccination efforts, 96.1% of deaths were attributed to patients with preexisting CMCs, thus it is important to examine how this population has endured changes.

OBJECTIVES: The purpose of this study was to identify differences in dietary habits, lifestyle habits, and food attitudes between those with CMCs compared to the populations without chronic medical conditions (non-CMCs) since the beginning of the COVID-19 pandemic.

METHODS: An …

Increasing populations and temperatures are expected to escalate food demands beyond production capacities, and the development of maize lines with better performance under heat stress is desirable. Here, we report that constitutive ectopic expression of a heterologous glutaredoxin S17 from Arabidopsis thaliana (AtGRXS17) can provide thermotolerance in maize through enhanced chaperone activity and modulation of heat stress-associated gene expression. The thermotolerant maize lines had increased protection against protein damage and yielded a sixfold increase in grain production in comparison to the non-transgenic counterparts under heat stress field conditions. The maize lines also displayed thermotolerance in the reproductive stages, resulting in …

The Associations Between Relative And Absolute Body Mass Index With Mortality Rate Based On Predictions From Stigma Theory, Gregory Pavela, Nengjun Yi, Luis Mestre, Stella Lartey, Pengcheng Xun, David B Allison

Children’s Nutrition Research Center Staff Publications

Background: The social consequences of obesity may influence health and mortality rate (MR), given obesity's status as a highly stigmatized condition. Hence, a high absolute body mass index (BMI) in conjunction with the stigmatization of a high BMI may each independently increase the rate of MR.

Objectives: We tested whether relative BMI, defined as ordinal rank within a social reference group jointly defined by age, sex, and race/ethnicity, is associated with MR independent of absolute BMI.

Methods: Data were from three nationally representative datasets: the Health and Retirement Study (n = 31,115), the National Health Interview Survey (NHIS, n = …
