Lethal And Sublethal Effects Of Exposure To Roundup 360 Plus For The Chaoborus Flavicans Larvae (Diptera: Chaoboridae), Zbigniew Adamski, Aleksandra Dziegelewska, Paulina Jakubiak, Piotr Klimaszyk

Turkish Journal of Zoology

The lethal and sublethal effects of Roundup (active substance glyphosate herbicide on phantom midge (Chaoborus flavicans, Meigen, 1830) larvae were checked in the range of concentrations from 20 to 2000 μg/L, in the five-day long tests. The herbicide caused the mortality of insects, with the LC$_{50}$ values ranging from 357.2 to 120.9 μg of glyphosate/L, for one and five days, respectively. The correlation coefficient >0.9 indicated a strong positive correlation between the concentration of Roundup in water and the mortality of C. flavicans. Also, the LT50 values indicate the toxic activity of the herbicide for the larvae. …

The Importance Of Shape Analysis Of The First Upper Molar In The Separation Of Two Subspecies Of The Hazel Dormouse (Muscardinus Avellanarius (Linnaeus, 1758)) In Northern Anatolia, Güli̇z Yavuz, Hati̇ce Mutlu Eyi̇son, Erkut Kivanç, Engi̇n Selvi̇, Nuri̇ Yi̇ği̇t, Ercüment Çolak

Turkish Journal of Zoology

Morphological features are important for intraspecific and interspecific variation. Teeth are important taxonomical characteristics because they can differ according to diet. Shape analysis of the first upper molar (M1) was used to determine geographical variations and effects of ecological changes on the population structure of Hazel dormice (Muscardinus avellanarius) living in Turkey. Both outline and landmark analysis, as well as a canonical variates analysis, showed significant differences in teeth shape between populations. With this technique, we separated out two subspecies: M. a. trapezius and M. a. abanticus.

Ecological Niche Comparison Among Closely Related Tree Species Of Lauraceae Using Climatic And Edaphic Data, Laura J. Giraldo-Kalil, Gonzalo E. Pinilla Buitrago, Andrés Lira-Noriega, Francisco Lorea-Hernández, Juan Núñez-Farfán

Publications and Research

ABSTRACT:

Edaphic specialization is considered to promote ecological differentiation among closely related species of Damburneya (Lauraceae) occurring in sympatry. However, little is known about the effects of soil and other key environmental factors like climate on the ecological niche and distribution of these tree species. Here, we assessed the role of climate and soil on niche divergence and potential distribution of four Damburneya species whose distributions span Central America and Mexico. We performed ecological niche modeling with MaxEnt using three sets of environmental data: climatic-only, edaphic-only, and a combination of both, to characterize species niches and suitable distribution areas. Niche …

Tcga Expression Analyses Of 10 Carcinoma Types Reveal Clinically Significant Racial Differences, Brian Lei, Xinyin Jiang, Anjana Saxena

Publications and Research

Epidemiological studies reveal disparities in cancer incidence and outcome rates between racial groups in the United States. In our study, we investigated molecular differences between racial groups in 10 carcinoma types. We used publicly available data from The Cancer Genome Atlas to identify patterns of differential gene expression in tumor samples obtained from 4112 White, Black/African American, and Asian patients. We identified race-dependent expression of numerous genes whose mRNA transcript levels were significantly correlated with patients’ survival. Only a small subset of these genes was differentially expressed in multiple carcinomas, including genes involved in cell cycle progression such as CCNB1 …

The association between long-term metformin use in type 2 diabetes mellitus (T2DM) and low vitamin B12 levels has been proven and screening for the same is recommended by American Diabetes Association (ADA) guidelines. The potential of the deficiency to cause or worsen diabetic peripheral neuropathy (DPN) in T2DM patients has been investigated in previous studies. However, the prevalence estimates of vitamin B12 deficiency in T2DM patients treated with long term metformin and having established DPN is lacking in our country. The aim of our study was to estimate the prevalence of vitamin B12 deficiency in T2DM patients with DPN …

Relationship Between Femoral Artery Intima-Media Thickness And Atherosclerosis In Patients With Chronic Kidney Disease- A One Year Hospital-Based Cross-Sectional Study, Dr. Somashekhar Sogi, Dr. Ravi Sarvi, Dr. Pradeep Goudar, Dr. Mallikarjun Karishetti, Dr.V.V Hattiholi, Dr.Meenakshi Sarvi

Digital Journal of Clinical Medicine

Introduction: Chronic kidney disease (CKD) is one of the leading causes of morbidity and mortality worldwide. CKD and Peripheral arterial disease both independently increase the risk for cardiovascular disease (CVD) events and contribute significantly to morbidity and mortality. There is limited data about the co-relation between ultrasound measures of the femoral artery in peripheral vascular disease (PVD) & renal functional status. This research hence will help us in the establishment of a relationship between femoral intima-media thickness (fIMT) with CKD. Also, IMT assessment might help in earlier detection of atherosclerotic plaques & hence PVD.

Family-Based Support As Social Determinants Of Health Protective Factor On Depression Of Parents Of Children With Autism Spectrum Disorder, Bisola E. Duyile

Theses and Dissertations

All parents experience challenges in their caregiving roles (Barańczuk & Pisula, 2020). However, parents raising a child/children with disabilities experience different social barriers (Oliver, 1996) that may also contribute to additional stressors in their caregiving role (Tomeny, 2016). Although these parents, on average, have reported greater symptoms of depression than parents of typically developing children, research shows that parents who reported receiving social support had lower symptoms of depression and stress (Das et al., 2017; Singh et al., 2017). Through the social determinants of health (SDOH) framework (ODPHP, 2022), the present study investigated informal/family-based support and its protective impact on …

Methods: Survey participants were recruited and questionnaires applied online. Residing in a food desert, using access to affordable produce as a proxy value, was the independent variable, while self- reported assessment of the child’s oral health status was the primary outcome variable. Analyses controlled for other indirect factors of pediatric oral health. Logistic regression was used to model the association between the self-reported access to healthy …

Salinization Impacts On Heterotrophic Respiration, Ecosystem Respiration, And Plant Productivity In Tidal Freshwater Marshes, Kelsie J. Moses

Theses and Dissertations

Tidal freshwater marshes have preserved substantial stocks of soil carbon, which represents carbon dioxide that is no longer in the atmosphere. There is conflicting evidence in the literature about how disturbances such as sea level rise and associated wetland salinization impact the accumulation and long-term stability of this stored carbon. The goal of this experiment was to quantify how salinization impacts total ecosystem respiration and its component parts, autotrophic and heterotrophic respiration. This was a microcosm experiment using a C4 plant (Spartina cynosuroides) grown in soil derived from C3 plant matter and exposed to different salinities (0 to …

Treponema Denticola Synthesizes C-Di-Amp And Encodes The Cdaa-Type Diadenylate Cyclase Cdaa, Claire R. O'Brien

Theses and Dissertations

Periodontitis is a form of oral disease characterized by dysbiosis of the oral microbiome, leading to inflammation, bone resorption, and in severe cases, entire tooth loss, affecting 42% of adults in the US. One of the bacteria most associated with periodontal disease progression is Treponema denticola (Td), an oral spirochete which inhabits the mouth in small quantities during health but which can dominate the biofilms that form during periodontal disease. The ability of Td to survive in a disease environment and contribute to the progression of disease requires the use of robust signaling networks. Analysis of Td cultures …

The Impact Of A Parent-Only Pediatric Obesity Intervention Program On Quality Of Life In Racially Diverse Children, Taylor Vashro

Theses and Dissertations

Pediatric obesity has been associated with significant decrements in pediatric quality of life (QOL) comparable with severe pediatric diseases such as cancer. Parenting interventions have yielded health benefits for children with obesity; however, few studies have investigated the impact of parent-focused interventions on QOL in children with overweight and obesity. This study investigated the impact of a 6-week intensive parenting intervention program on the QOL of 5-12 year old, predominantly Black children with overweight and obesity. Parents were randomized into either the parenting intervention (NOURISH+) or a control group, and QOL, as well as variables related to child and parenting …

The Impact Of Patient Characteristics On Dysphagia Therapy Utilization And Feeding Outcomes For Premature Infants In The Neonatal Intensive Care Unit, Tiana Nguyen

Theses and Dissertations

Medical advances have significantly increased the survival rates of preterm infants at lower gestational ages. However, infants born at lower gestational ages have an increased risk for developmental disabilities and oral feeding difficulties. A stay in the neonatal intensive care unit (NICU) is very costly and inadequate oral feeding is the most common barrier to discharge for premature infants. Infants can receive dysphagia therapy services during their NICU stay that focuses on the development of oral feeding and swallowing skills. However, literature to this date has mainly focused on the impact of therapy services for premature infants after NICU discharge. …

Engagement in prevention can prevent or prolong cancer, early detection through engagement in cancer screening improves cancer trajectories and compliance …

Breaking Bread & Boundaries : Finding Home In Every Bite, Steffi Ann Braganza

Theses and Dissertations

Raised outside of their “passport” countries, Third Culture Individuals (TCIs) often experience a lack of rootedness and belonging, and home is often everywhere and nowhere. Childhood food memories can provide the sense of connection and identity TCIs crave. Four Qatar-raised TCIs, from very different backgrounds share memories of their childhood comfort foods, now hybridized dishes, that reflect their unique third culture experiences. Each dish, in turn, inspired the creation of a bespoke set of cooking /dining ware designed to trigger a specific sensory memory: the sight, smell, touch, or sound associated with the original comfort dish. This specialized cooking/dining ware …

Theses and Dissertations

Targeting dietary behaviors is a predominant strategy to reduce rates of obesity among African Americans, across the lifespan. Notably, dietary behaviors are shaped by social, cultural and environmental affordances. This study integrated Theory of planned behavior (TPB), identity-based motivation, and mindset theory to unearth cultural mechanisms that inform motivations to eat healthy among African American college students. This project employed a cross-sectional (Study 1) and experimental design (Study 2) to contextualize the antecedents of intentions to eat healthy among African American college students. Recruitment occurred via university-wide digital channels. Eligible participants: were 18+ years; Black/African American; were undergraduate students; and …

The Private Costs Of Behavioral Interventions, Avishalom Tor

Journal Articles

The increasing popularity of behavioral interventions—also known as nudges—is largely due to their perceived potential to promote public and private welfare at dramatically lower costs than those of traditional regulatory instruments, such as mandates or taxes. Yet, though nudges typically involve low implementation costs, scholars and policymakers alike tend to underestimate their often-substantial private costs. Once these costs are accounted for, most nudges turn out to generate significantly lower net benefits than assumed, and some prove less efficient or less cost-effective than traditional instruments. At other times, the private costs of behavioral interventions are sufficiently large to render them socially …

This study utilized a cross-sectional survey design to gather quantitative data. College undergraduate students (N = 652) from a Midwestern university were recruited via email. Data were analyzed in SPSS, using descriptive statistics, multiple linear regression, ordinal, and binary logistic …

Development Of A Chemical Biology Approach To Uncover The Influence Of Sequence Variations On Ces1 Activity In Live Cells, Samuel James Knebel

Masters Theses

Drug metabolism is the biochemical process of modifying drugs to detoxify and remove them through enzymatic transformations. These biotransformation’s occur primarily in the liver and are critical to understanding how pharmaceutical compounds are chemically altered inside the human body. Human carboxylesterases (CESs) catalyze the hydrolysis of esters, amides, thioesters, and carbamates. CES-mediated hydrolysis plays an important role in the metabolism of many drugs including the first FDA approved antiviral treatment for COVID-19, remdesivir (Veklury), the seizure control medication rufinamide (Banzel), and the flu antiviral drug oseltamivir (Tamiflu). CES activity is known to be influenced by a variety of factors including …

Three Essays On The Effects Of Parental Income And Labor Supply On Child Health And Labor Market Outcomes., Kassahun Mamo Geleta

Graduate Research Theses & Dissertations

This dissertation constitutes three separate essays on labor and health economics using the Panel Study of Income Dynamics (PSID) dataset. The first essay examines the long-run effect of childhood poverty on labor market outcomes using propensity score matching (PSM) and average causal mediation effect (ACME) methods. The results show that persistent childhood poverty significantly decreases average annual labor income and hours worked, whereas it increases the number of weeks unemployed per annum during adulthood. The study also shows that a significant portion of the total effect of childhood poverty on labor market outcomes passes indirectly through its negative effect on …

Intergenerational Transmission Of Parenting: Does Emotion Regulation Buffer The Effect Of Negative Early Care Experiences On The Cortisol Stress Response And Subsequent Caregiving?, Erin Rochelle Mckay

Graduate Research Theses & Dissertations

A phenomenon known as the intergenerational transmission of parenting, where children tend to parent their children in a manner similar to how their own parents provided care, has received notable attention within developmental research. While several mechanisms focusing on cognitive and psychological factors have been proposed, there is less research examining biological mechanisms within the intergenerational transmission of parenting framework, especially when considering caregiving behavior exhibited in the context of child distress. Further, few studies have examined parent attributes which may disrupt the intergenerational transmission of parenting. The current study seeks to examine the hypothalamic-pituitary-adrenal (HPA) axis stress response as …
