Research outputs 2022 to 2026

Introduction Haemoglobin variants and preeclampsia (PE) are associated with adverse fatal events of which oxidative stress may be an underlying factor. Oxidative stress (OS) among preeclamptic women with haemoglobin variants has been well established. It is, however, unclear whether haemoglobin variants induce OS to aggravate the risk of adverse foeto-maternal outcomes in pregnant women with preeclampsia. We measured the levels of OS biomarkers and determined the association between haemoglobin variants, and adverse foeto-maternal outcomes among pregnant women with PE. Methods This multi-centre prospective study recruited 150 PE women from three major health facilities in both Bono and Bono east regions …

Measuring Dna Modifications With The Comet Assay: A Compendium Of Protocols, Awadhesh N. Jha

School of Biological and Marine Sciences

The comet assay is a versatile method to detect nuclear DNA damage in individual eukaryotic cells, from yeast to human. The types of damage detected encompass DNA strand breaks and alkali-labile sites (e.g., apurinic/apyrimidinic sites), alkylated and oxidized nucleobases, DNA–DNA crosslinks, UV-induced cyclobutane pyrimidine dimers and some chemically induced DNA adducts. Depending on the specimen type, there are important modifications to the comet assay protocol to avoid the formation of additional DNA damage during the processing of samples and to ensure sufficient sensitivity to detect differences in damage levels between sample groups. Various applications of the comet assay have been …

Muscle deconditioning and impaired vascular function in the lower extremities (LE) are among the long‐term symptoms experienced by COVID‐19 patients with a history of severe illness. These symptoms are part of the post‐acute sequelae of Sars‐CoV‐2 (PASC) and currently lack evidence‐based treatment. To investigate the efficacy of lower extremity electrical stimulation (E‐Stim) in addressing PASC‐related muscle deconditioning, we conducted a double‐blinded randomized controlled trial. Eighteen (n = 18) patients with LE muscle deconditioning were randomly assigned to either the intervention (IG) or the control (CG) group, resulting in 36 LE being assessed. Both groups received daily 1 h E‐Stim …

Using The I3 Model To Understand Overeating, Kenneth Herbst, Mark Peterson, Suman Saha

Journal of Applied Marketing Theory

This paper uses a conceptual framework, the I³ Model (pronounced the ‘I-Cubed Model’), for understanding the influence of external and internal factors on eating behavior. According to the I³ Model (Instigation, Impellance and Inhibition), three processes can explain how overeating can occur. This paper provides support for the I³ Model through a field experiment and two laboratory experiments. The I³ Model sheds light on the nature of overeating when a perfect storm arises in which instigation and impellance are strong and inhibition is weak. The identification of this perfect-storm condition suggests that …

Cognitive And Academic Performance Of Rural Zambian Youth Exposed To Hiv, Sophie Jago, Joseph Mwaba Chirwa, Mei Tan, Philip E Thuma, Elena L Grigorenko

Faculty, Staff and Students Publications

Studies focusing on children affected by HIV have shown that they have generally lower academic performance, however, few studies separate children who are HIV exposed and infected (CHEI) and those who are HIV exposed but uninfected (CHEU). Importantly, in rural sub-Saharan Africa, the majority of studies on CHEI and CHEU examine academic performance indirectly based on cognitive test scores. Therefore, studies assessing the effects of HIV on academic achievement directly for CHEI and CHEU are needed. This article evaluates the effects of HIV-infection on cognitive and academic performance by comparing CHEI (n = 82) and CHEU (n = 1045) aged …

Mathematical Models For Thalassemia, Hamda Mohammed Al Dhaheri

Theses

Thalassemia is a genetic blood disorder caused by gene mutation or deletion in a blood protein called hemoglobin. Treatment of thalassemia requires a life-long blood transfusion and removal of excessive iron in the blood stream, which usually causes a big pressure on health care systems. Various forms of thalassemia control measures have been used to reduce the prevalence of thalassemia major. This has resulted in a substantial reduction in the prevalence of thalassemia. However, the thalassemia carrier population remains high, which could lead to an increase in the thalassemia major population through carrier-to-carrier marriages. Thus, we developed two mathematical models …

The Perceptions And Effects Of Nutrition On Worker Health And Productivity In Construction, Matthew Scott Howell

Construction Management

Construction workers often have poor dietary habits due to poor nutrition education, lack of nutritious food options, and social stigma. These habits often lead to health problems like obesity, diabetes, and heart disease which can decrease productivity and put workers at risk of on-site injury. This preliminary study examines how nutrition impacts worker safety and productivity. A survey was distributed to six students involved in construction work for Cal Poly’s Residential Construction course. This survey identified their eating habits and inhibitors for healthy eating. Two meals, one with high nutritional value and one with low nutritional value, were given to …

Classifying Severe And Enduring Anorexia Nervosa: A Literature Review, Phoenix Black

University Honors Theses

Little focus is placed on the subsection of the eating disorder patient population who struggle chronically with their illness. This review synthesizes research on the topic to identify gaps in knowledge and reflect on implications for diagnosis and classification of severe and enduring anorexia nervosa. There was some variability between both clinicians and researchers who focused on this patient population, which is discussed based on different classifying criteria used to include or exclude an individual into the study. This review considers traditional methods used for classifying psychiatric diagnoses in relation to this disorder.

A Scoping Review Of Iodine And Fluoride In Pregnancy In Relation To Maternal Thyroid Function And Offspring Neurodevelopment., Adrianne K. Griebel-Thompson, Scott Sands, Lynn Chollet-Hinton, Danielle Christifano, Debra K. Sullivan, Holly Hull, Susan E. Carlson

Manuscripts, Articles, Book Chapters and Other Papers

Iodine (I), an essential nutrient, is important for thyroid function and therefore growth and development. Fluoride (F), also an essential nutrient, strengthens bones and teeth, and prevents childhood dental caries. Both severe and mild-to-moderate I deficiency and high F exposure during development are associated to decreased intelligence quotient with recent reports associating high levels of F exposure during pregnancy and infancy to low intelligence quotient. Both F and I are halogens, and it has been suggested that F may interfere with the role of I in thyroid function. We provide a scoping review of the literature on I and F …

Faculty, Staff and Student Publications

Frailty is associated with adverse outcomes in heart failure (HF). A parsimonious frailty index (FI) that predicts outcomes of older, multimorbid patients with HF could be a useful resource for clinicians. A retrospective study of veterans hospitalized from October 2015 to October 2018 with HF, aged ≥50 years, and discharged home developed a 10-item parsimonious FI using machine learning from diagnostic codes, laboratory results, vital signs, and ejection fraction (EF) from outpatient encounters. An unsupervised clustering technique identified 5 FI strata: severely frail, moderately frail, mildly frail, prefrail, and robust. We report hazard ratios (HRs) of mortality, adjusting for age, …

Michigan Tech Publications, Part 1

Artificially induced polyploidization is one of the most effective techniques for improving the biological properties and creating new cultivars of fruit trees. Up to now, systematic research on the autotetraploid of sour jujube (Ziziphus acidojujuba Cheng et Liu) has not been reported. ‘Zhuguang’ is the first released autotetraploid sour jujube induced with colchicine. The objective of this study was to compare the differences in the morphological, cytological characteristics, and fruit quality between diploid and autotetraploid. Compared with the original diploid, ‘Zhuguang’ showed dwarf phenotypes and decreased tree vigor. The sizes of the flowers, pollen, stomata, and leaves of ‘Zhuguang’ were …

Fibroblast Growth Factor 19 Secretion And Function In Perinatal Development, Caitlin Vonderohe, Gregory Guthrie, Douglas G Burrin

Faculty, Staff and Students Publications

Limited work has focused on fibroblast growth factor-19 (FGF19) secretion and function in the perinatal period. FGF19 is a potent growth factor that coordinates development of the brain, eye, inner ear, and skeletal system in the embryo, but after birth, FGF19 transitions to be an endocrine regulator of the classic pathway of hepatic bile acid synthesis. FGF19 has emerged as a mediator of metabolism and bile acid synthesis in aged animals and adults in the context of liver disease and metabolic dysfunction. FGF19 has also been shown to have systemic insulin-sensitizing and skeletal muscle hypertrophic effects when induced or supplemented …

Faculty, Staff and Students Publications

BACKGROUND AND AIMS: In biliary atresia, serum bilirubin is commonly used to predict outcomes after Kasai portoenterostomy (KP). Infants with persistently high levels invariably need liver transplant, but those achieving normalized levels have a less certain disease course. We hypothesized that serum bile acid levels could help predict outcomes in the latter group.

APPROACH AND RESULTS: Participants with biliary atresia from the Childhood Liver Disease Research Network were included if they had normalized bilirubin levels 6 months after KP and stored serum samples from the 6-month post-KP clinic visit ( n = 137). Bile acids were measured from the stored …

Nitric Oxide-Driven Modifications Of Lipoic Arm Inhibit Α-Ketoacid Dehydrogenases, Gretchen L Seim, Steven V John, Nicholas L Arp, Zixiang Fang, David J Pagliarini, Jing Fan

2020-Current year OA Pubs

Pyruvate dehydrogenase complex (PDHC) and oxoglutarate dehydrogenase complex (OGDC), which belong to the mitochondrial α-ketoacid dehydrogenase family, play crucial roles in cellular metabolism. These multi-subunit enzyme complexes use lipoic arms covalently attached to their E2 subunits to transfer an acyl group to coenzyme A (CoA). Here, we report a novel mechanism capable of substantially inhibiting PDHC and OGDC: reactive nitrogen species (RNS) can covalently modify the thiols on their lipoic arms, generating a series of adducts that block catalytic activity. S-Nitroso-CoA, a product between RNS and the E2 subunit's natural substrate, CoA, can efficiently deliver these modifications onto the lipoic …

Epibionts Provide Their Basibionts With Associational Resistance To Predation But At A Cost, S Downes, L Firth, Am Knights

School of Biological and Marine Sciences

Epibiosis is increasingly considered a survival strategy in space-limited environments. However, epibionts can create a new interface between its host, environment and potential predators which may alter predator-prey relationships and biological functioning. Ex-situ experiments investigated the potential costs and benefits of epibiont barnacles on mortality and feeding rate of the mussel, Mytilus edulis, and its predator, the whelk Nucella lapillus. Mussels with living epibiont barnacles suffered no mortality from whelk predation, but when barnacles were absent, mortality was ~21% over 48 days. Further comparisons revealed the structural complexity of barnacles provided mussels with protection from whelk predation, while the presence …
