Current And Novel Tools In The Health Assessment Of Large Whales, Kelly Ann Cates

Fisheries

Alaskan marine ecosystems are undergoing unprecedented change and species are facing increasingly variable and potentially inhospitable habitats. As top predators, marine mammals serve an important role as sentinels of ecosystem health. With their high site fidelity, abundant numbers, coastal presence and role as a top predator, humpback whales (Megaptera novaeangliae) provide a meaningful view into current ecosystem conditions and processes. In order to tap into their usefulness as bioindicators the basic physiology of humpback whales needs to be understood. Physiological indices can provide valuable information about fecundity, survival, health and population age structuring which is fundamental to cetacean research and …

Bridging Expert Knowledge And Fisheries Data To Inform Assessment And Management Of Rockfishes In The Gulf Of Alaska, Jesse Gordon

Hebron University Research Journal-A (Natural Sciences) - (مجلة جامعة الخليل للبحوث- أ (العلوم الطبيعيه

Defatted sesame meals were extracted for ethanol soluble sugars and the effects of different conditions for extraction were compared for the composition and yield of the extracts. Xylooligosaccharides (XOS) were generated from the hemicellulose fraction (following deproteinization) using endo-xylanase from Bacillus subtilis. The condition which produced the highest yield for total soluble sugars was 40% ethanol at 60 º C for 30 minutes for de-hulled (A) and hulled (B) sesame meal samples. Ultrasonication treatment of the samples had no significant benefit over water-bath. Sugar composition analysis of the samples showed the presence of glucose, arabinose, galactose and xylose with trace …

Prospects In Connecting Genetic Variation To Variation In Fertility In Male Bees, Garett P. Slater, Nicholas M A Smith, Brock A. Harpur

Department of Entomology Faculty Publications

Bees are economically and ecologically important pollinating species. Managed and native bee species face increasing pressures from human-created stressors such as habitat loss, pesticide use, and introduced pathogens. There has been increasing attention towards how each of these factors impacts fertility, especially sperm production and maintenance in males. Here, we turn our attention towards another important factor impacting phenotypic variation: genetics. Using honey bees as a model, we explore the current understanding of how genetic variation within and between populations contributes to variation in sperm production, sperm maintenance, and insemination success among males. We conclude with perspectives and future directions …

Why Do Graphic Health Warnings Fail: An Explanatory Case Study On The Persistence Of Smoking Behavior Among Male Adult Smokers In A Rural And Low-Income Setting In The Philippines, John Rafael Arda, Ashley Gabrielle Jeanjaquet, Navin John Pasia, John Dominic Mari Rafael, Danyz Samantha Rita, Kaye Bernice Siao, Jecelyn Grace Yparraguirre, Genejane Adarlo

Health Sciences Faculty Publications

Background: The Philippines enacted in 2014 Republic Act No. 10643 that mandated the printing of Graphic Health Warnings on tobacco packages. However, smoking behavior among male smokers in the country, particularly in rural and low-income areas, persists even if the Graphic Health Warnings are according to the guidelines set by the World Health Organization. Hence, this explanatory case study aims to examine why and how most male adult smokers in a rural and low-income setting in the Philippines fail to quit smoking despite the presence of Graphic Health Warnings on tobacco packages.

Methods: Forty-four male adult smokers from Barangay Urdaneta …

What Is The Most Effective Management For Patients With Concomitant Gallstones And Bile Duct Stones?, Stephanie Mccarney

Theses and Graduate Projects

Background: Gallstone disease is common with a high prevalence in developed nations and is expected to rise as the obesity and metabolic syndrome epidemic worsens. The associated relationship between gallstone and biliary tract disease is complex. The most effective treatment approach for patients with concomitant gallstones and bile duct stones is controversial. Multiple different combinations of one-step and two-step endoscopic and/or surgical techniques exist. Advancements in laparoscopic and endoscopic methods have paved the way for a minimally invasive approach to managing cholecystocholedocholithiasis (CCL).

Methods: A literature review was conducted via systematic search of Google Scholar and PubMed to …

Effects Of Palmitate On The Expression Of Inflammatory Cytokines In Microglial Cells, Shiyu Ma

Seton Hall University Dissertations and Theses (ETDs)

Obesity has become a pandemic health issue for the development of more serious illnesses such as insulin resistance, cardiovascular diseases, and hypertension. Among those pathological conditions, low grade chronic inflammation triggered by saturated fatty acids (SFA) such as palmitate (PA) has been suggested to be the culprit of crimes and various signaling modulators ranging from cellular surface receptors such as toll like receptors (TLRs) and G- protein – coupled receptor 40 (GPR40) to intracellular kinases like mitogen-activated protein kinase (MAPK) and protein kinase C (PKC) have been postulated. In this study, mouse BV2 cells were treated with different concentrations of …

C. Elegans Response To Cadmium Toxicity, Brian James Earley

Arts & Sciences Graduate Student Theses and Dissertations

Cadmium is an environmental pollutant and significant health hazard that is similar to the physiological metal zinc. Residing in the same group of the periodic table, cadmium and zinc share chemical characteristics that are important for their industrial uses in electroplating, batteries, pigments, and metal alloys. The similarities of ionic cadmium and zinc have significant repercussions on biological systems. While it has long been clear that cadmium is toxic to biological systems, the mechanisms of cadmium toxicity remain poorly understood. In contrast, mechanisms of zinc homeostasis have been elucidated in growing detail. In C. elegans high zinc homeostasis is regulated …

Association Of Structural Variation (Sv) With Cardiometabolic Traits In Finns, Lei Chen

Arts & Sciences Graduate Student Theses and Dissertations

Cardiovascular diseases (CVDs) are known to be associated with a variety of quantitative risk factors such as cholesterol, metabolites, and insulin. Understanding the genetic basis of these quantitative traits can shed light on the etiology, prevention, diagnosis, and treatment of disease. However most prior trait-mapping studies have focused on single nucleotide variants (SNVs) and Indels, with the contribution of structural variation (SV) remaining unknown. In this thesis, we present the results of a study examining genetic association between SVs and cardiometabolic traits in the Finnish population. In the first chapter, we used sensitive methods to identify and genotype 129,166 high-confidence …

Investigating The Differentiation And Functional Maturation Of Stem Cell-Derived Β Cells, Leonardo Velazco-Cruz

Arts & Sciences Graduate Student Theses and Dissertations

Diabetes mellitus is a chronic and global disease rapidly growing in prevalence. Diabetes can be characterized by the dysfunction or death of the glucose sensing insulin secreting  cell.  cells are located within the islet of Langerhans (islet), a tissue within the pancreas. Human islets are critical for the study and treatment of diabetes. However, they can only be obtained from cadaveric organ donors. These cadaveric islets do not proliferate and can only be maintained in vitro for short periods of time, making their availability rare and fleeting. Stem cell-derived -like cells can be generated in indefinite amounts and …

Copper-Mediated Regulation Of A Traditional Iron Uptake System In Uropathogenic Escherichia Coli., George Lwanga Katumba

Arts & Sciences Graduate Student Theses and Dissertations

Transition metals constitute an important part of the host-pathogen interface. Iron is an essential nutrient that functions as a cofactor for numerous bacterial and host proteins, as either a ligand for oxygen in carrier proteins or an enzyme catalytic site due to its natural redox properties. As part of the innate immune response, infected hosts sequester iron from pathogens to limit their growth, a phenomenon known as nutritional immunity. On the other hand, copper ions are deployed at infection sites as a potent antimicrobial agent to kill bacteria. The ability to survive within multiple, often harsh, microenvironments is fundamental to …

Exploring Contextual Differences In Environment And Policy Strategies To Promote Physical Activity In Disadvantaged Communities, Natalicio Hector Serrano

Arts & Sciences Graduate Student Theses and Dissertations

The benefits of physical activity for health are far reaching, including the reduced risk of several chronic diseases. However, only about 24% of US adults meet recommended guidelines of physical activity, with traditionally disadvantaged populations such as rural residents and persons of color facing even lower rates. Ecological models of health behavior help to understand correlates of physical activity that impact population health, but may not be as useful in disadvantaged populations where the evidence base is either lacking or not as rigorous. Furthermore, measures and methods may be underdeveloped in disadvantaged populations and there is a lack of understanding …

Comparative Analysis Of Longevity And Stress Resiliency Benefits Of Supplementation With High-Antioxidative Capacity Juices In Organisms That Are Representative Of Humans, Meghan Long

Honors Scholar Theses

Neurodegenerative disease presents itself in a complex array of illnesses that is increasingly affecting the geriatric population. There has not been research on a common cause since there are a culmination of reasons that are probable ranging from genetic to environmental factors. Antioxidants have been known to prevent and protect against the damage that is otherwise caused by reactive oxygen species (ROS). Thus, high-capacity antioxidant juices supplemented into the diet of animal models such as Caenorhabditis elegans, Drosophila melanogaster, rats, and humans will allow for the study of the possible benefits.

Although a conclusion and common causation on the usage …

Torres-Llanez, Adrian Hernandez-Mendoza, Belinda Vallejo-Cordoba, Andrea M. Liceaga, Aaron E. Gonzalez-Cordova

Department of Food Science Faculty Publications

The objective of the present study was to evaluate the potential antioxidant and angiotensin converting enzyme inhibition (ACEI) activity of edible insect flours fermented with Lactococcus lactis strains. For the fermentation, mealworm and grasshoppers flours were dissolved (0.5% w/v) in buffer solution (pH 7.0) and individually inoculated (3%) with Lactococcus lactis strains (NRRL B-50571, NRRL B-50572). The samples were incubated for 72 h at 30 ◦C, and the pH was recorded. The degree of hydrolysis (DH) and protein content were determined. The total polyphenol compounds, antioxidant activity (ABTS, DPPH, ORAC, and FRAP), and ACEI of the <3 kDa fractions were ana- lyzed. The pH of the fermented samples decreased to 3.5–3.9 (p < 0.05). The fermented grasshopper flour showed an increased DH (0.42%) and overall higher total polyphenol content (8.23 mg Gallic Acid Equivalent/mL). In general, the highest antioxidant activity was for the grasshopper fractions fermented for 24 h by Lactococcus lactis NRRL B-50572, which also showed 23.47% ACEI inhibition with an IC50 of 0.97 mg/mL. The peptide profile obtained increased after fermentation, being higher for the mealworm flour fermented sample. This study presents, for the first time, the use of specific strains of Lactococus lactis for fermenting edible insect-derived products in the production of bioactive compounds with potential antioxidant and antihypertensive activity.
