BACKGROUND: Small cell lung cancer (SCLC) is an aggressive lung cancer subtype that is associated with high recurrence and poor prognosis. Due to lack of potential drug targets, SCLC patients have few therapeutic options. MicroRNAs (miRNAs) provide an interesting repertoire of therapeutic molecules; however, the identification of miRNAs regulating SCLC growth and metastasis and their precise regulatory mechanisms are not well understood.

METHODS: To identify novel miRNAs regulating SCLC, we performed miRNA-sequencing from donor/patient serum samples and analyzed the bulk RNA-sequencing data from the tumors of SCLC patients. Further, we developed a nanotechnology-based, highly sensitive method to detect microRNA-1 (miR-1, …

Gut microbiota plays a crucial role in inflammatory bowel diseases (IBD) and can potentially prevent IBD through microbial-derived metabolites, making it a promising therapeutic avenue. Recent evidence suggests that despite an unclear underlying mechanism, red cabbage juice (RCJ) alleviates Dextran Sodium Sulfate (DSS)-induced colitis in mice. Thus, the study aims to unravel the molecular mechanism by which RCJ modulates the gut microbiota to alleviate DSS-induced colitis in mice. Using C57BL/6J mice, we evaluated RCJ's protective role in DSS-induced colitis through two cycles of 3% DSS. Mice were daily gavaged with PBS or RCJ until the endpoint, and gut microbiota composition …

Normal pregnancy relies on inflammation for implantation, placentation, and parturition, but uncontrolled inflammation can lead to poor maternal and infant outcomes. Maternal diet is one modifiable factor that can impact inflammation. Omega-3 and -6 fatty acids obtained through the diet are metabolized into bioactive compounds that effect inflammation. Recent evidence has shown that the downstream products of omega-3 and -6 fatty acids may influence physiology during pregnancy. In this review, the current knowledge relating to omega-3 and omega-6 metabolites during pregnancy will be summarized.

Ventricular Tachycardia In A Pediatric Patient With High-Risk Thrombotic Thrombocytopenia Purpura, Taylor J. Kratochvil, Jeffrey A. Robinson

Journal Articles: Pediatrics

An 8-year-old previously healthy male was diagnosed with thrombotic thrombocytopenic purpura (TTP) and increased serum cardiac troponin I. Telemetry recorded non-sustained ventricular tachycardia, without ST-segment changes or other abnormalities on serial electrocardiogram. This case illustrates that cardiac monitoring by telemetry should be considered in high-risk TTP with elevated cardiac troponin.

Journal Articles: Pediatrics

Vitamin A (retinol) is essential for normal fetal development, but the recommendation for maternal dietary intake (Retinol Activity Equivalent, RAE) does not differ for singleton vs. twin pregnancy, despite the limited evaluation of retinol status. Therefore, this study aimed to evaluate plasma retinol concentrations and deficiency status in mother-infant sets from singleton vs. twin pregnancies as well as maternal RAE intake. A total of 21 mother-infant sets were included (14 singleton, 7 twin). The HPLC and LC-MS/HS evaluated the plasma retinol concentration, and data were analyzed using the Mann-Whitney U test. Plasma retinol was significantly lower in twin vs. singleton …

Evaluation Of Vitamin E Isoforms In Placental Tissue And Their Relationship With Maternal Dietary Intake And Plasma Concentrations In Mother-Infant Dyads, Ishani Jhamb, Alyssa Freeman, Michelle R. Lotfi, Matthew Van Ormer, Corrine K. Hanson, Ann Anderson-Berry, Melissa K. Thoene

Journal Articles: Pediatrics

α-tocopherol is a vitamin E isoform with potent antioxidant activity, while the γ-tocopherol isoform of vitamin E exerts more pro-inflammatory effects. In maternal-fetal environments, increased plasma α-tocopherol concentrations are associated with positive birth outcomes, while higher γ-tocopherol concentrations are linked with negative pregnancy outcomes. However, little is known about tocopherol concentrations in placental tissue and their role in modulating placental oxidative stress, a process that is implicated in many complications of pregnancy. The objectives of this research are to evaluate the concentrations of α- and γ-tocopherol in placental tissue and assess relationships with maternal and umbilical cord plasma concentrations. A …

Reflections On “Personal Responsibility” After Covid And Dobbs: Doubling Down On Privacy, Susan Frelich Appleton, Laura A. Rosenbury

Scholarship@WashULaw

This essay uses lenses of gender, race, marriage, and work to trace understandings of “personal responsibility” in laws, policies, and conversations about public support in the United States over three time periods: (I) the pre-COVID era, from the beginning of the American “welfare state” through the start of the Trump administration; (II) the pandemic years; and (III) the present post-pandemic period. We sought to explore the possibility that COVID and the assistance programs it inspired might have reshaped the notion of personal responsibility and unsettled assumptions about privacy and dependency. In fact, a mixed picture emerges. On the one hand, …

Fungicide Sensitivity In P. Tritici-Repentis Diverse Population And Phenotyping Of Spelt Wheat For Multiple Diseases, Zunera Shabbir

Electronic Theses and Dissertations

Pyraclostrobin, a QoI fungicide, is extensively used in the management of fungal leaf spot diseases. In this study, 215 P. tritici-repentis isolates collected from wheat fields in South Dakota were evaluated for their sensitivity to Pyraclostrobin. Of 215 isolates, 48 isolates (22%) exhibited insensitivity based on G143A mutation and EC50 values using spore germination assay. Our results indicate reduced sensitivity to insensitivity to pyraclostrobin in some isolates suggesting regular monitoring of the P. tritici-repentis population to QoI fungicides is essential to track the evolution of insensitive population. Spelt wheat (Triticum spelta L.) is an ancient cereal that is gaining small …

Development Of Corn Kernel-Based Biocomposite Films For Food Packaging Applications, Swastika Bera

Electronic Theses and Dissertations

Most of the current and active food packaging resources and methods are nonbiodegradable and nonrenewable therefore harmful to the environment. Due to this, alternate sources of food packaging materials are in high demand. In this study, a bio-composite film has been developed, with Corn kernel powder as fiber reinforcement which is mixed with gelatin, and lignin two biopolymers as the matrix. The effect of Corn Kernel (CK) reinforcement on the Gelatin/Lignin (G/L) matrix on mechanical and barrier properties has been studied. CK has shown great potential as reinforcement to natural polymer, gelatin, and lignin (G/L) for food packaging applications as …

Effects Of Dietary Genistein And Fugacity Modelling In An Aquaculture System, Travis Schaeffer

Electronic Theses and Dissertations

Fish production from aquaculture has continued to grow over the past several decades, with finfishes being fed formulated, fish meal-based diets supporting most of that industry’s growth. However, increased demand and costs, coupled with static volume and erratic supplies of fish meal, has resulted in the use of alternative plant-derived protein sources. A common oilseed protein source is soybean meal (SBM), because of its protein content and amino acid profile; however, it also contains multiple anti-nutritional factors, including phytoestrogens. Phytoestrogens are naturally produced, estrogenmimicking compounds, with isoflavones receiving the most investigation as higher levels of these compounds occur within SBM. …

Federal Nonenforcement At A Crossroads, Zachary Price

Faculty Scholarship

As a novel aspect of “presidential administration”—the president- centered approach to federal governance discussed in a 2001 article by then-Professor and future Supreme Court Justice Elena Kagan—broad federal nonenforcement policies have been a major source of controversy in the past decade. As illustrated by the Obama Administration’s ex- pansive nonenforcement policies relating to marijuana, immigration, and Affordable Care Act implementation, recent presidents have recog- nized nonenforcement’s potential to reshape statutory law to suit an administration’s policy aims. This Article takes stock of this develop- ment as it relates to the past three presidential administrations. While advocating a limited view of …

Effects Of Pregnancy And Lactation On Muscle-Tendon Morphology, Nicole Danos, Marjorie Patrick, Jacob Barretto, Francesca Bilotta, Megan Lee

Biology: Faculty Scholarship

Pregnancy and lactation hormones have been shown to mediate anatomical changes to the musculoskeletal system that generates animal movement. In this study, we characterize changes in the medial gastrocnemius muscle, its tendon and aponeuroses that are likely to have an effect on whole animal movement and energy expenditure, using the rat model system, Rattus norvegicus. We quantified muscle architecture (mass, cross-sectional area, and pennation angle), muscle fiber type and diameter, and Young's modulus of stiffness for the medial gastrocnemius aponeuroses as well as its contribution to Achilles tendon in three groups of three-month-old female rats: virgin, primiparous pregnant, and primiparous …

Changes In The Microbiome Of The Sea Anemone Exaiptasia Diaphana During Bleaching From Short-Term Thermal Elevation, Jamison R. Sydnor, Jamie Lopez, Gordon V. Wolfe, Lisa Ott, Cawa Tran

Biology: Faculty Scholarship

We examined the response of microbial communities in the model sea anemone Exaiptasia diaphana (Aiptasia) to short-term thermal elevation. Through 16S rRNA gene sequencing, we characterized the microbiomes of symbiotic (with algal symbionts) and aposymbiotic (bleached) anemones under ambient (27°C) and heat-stressed (34°C) conditions for 8-10 days, using both replicated endpoint and non-replicated time-course approaches. Consistent with prior studies, we observed a stable abundance of bacteria from the families Alteromonadaceae and Rhodobacteraceae, though with wide variation among individual anemones. We observed that symbiotic state conferred a larger impact on the microbiome than heat stress, implying the microbiome may play a …

Analysis Of Factors Affecting Cross-Boundary Knowledge Mobilization In Agri-Food Supply Chains: An Integrated Approach, Guoqing Zhao, Huilan Chen, Shaofeng Liu, Denis Dennehy, Paul Jones, Carmen Lopez

Plymouth Business School

Agri-food supply chains (AFSCs) link produce from farm-to-fork. Over 80% of businesses operating in AFSCs are small and medium-sized enterprises (SMEs) that lack the necessary resources to make knowledge accessible and usable to other stakeholders. To enhance AFSCs’ performance, we adopt an integrated approach to analyze factors affecting knowledge mobilization (KMob) across boundaries. Thematic analysis of data collected from interviews reveals 11 KMob factors. We apply total interpretive structural modeling (TISM) to identify influential relationships among these factors, and fuzzy cross-impact matrix multiplication applied to classification (MICMAC) to distinguish each factor’s role in the system. Our results complement previous studies …

Preconception Care For People With Health Conditions: What Approaches Work, For Whom, And In What Circumstances? A Realist Review, Heather Hopper, Kerryn Husk, Kate Maslin, Bridie Kent, Amanda Wanner, Jill Shawe

School of Nursing and Midwifery

Preconception care for people with chronic health conditions is recommended in view of the implications for them and their offspring during pregnancy and beyond. This realist review of published and grey literature explored factors that explain why people seek or receive appropriate preconception counseling and why they engage in recommended health behavior change prior to pregnancy. Fifty-two studies contributed to phase one synthesis, and 38 studies provided explanations in phase two. Ten program theories were developed, explored, and refined through iterative discussion and coding. Causal explanations of the ways in which components of preconception care contribute to effective access to …

School Attendance Information Or Conditional Cash Transfer? Evidence From A Randomized Field Experiment In Rural Bangladesh, Tomoki Fujii, Christine Ho, Rohan Ray, Abu S. Shonchoy

Research Collection School Of Economics

Low school attendance remains an important challenge in resource-poor settings with cash and information constraints. We compare conditional cash transfer (CCT) treatments with framing variations (gain and loss) against attendance information treatment as interventions to address these constraints in a unified framework. Our randomized evaluation shows CCT treatments increase attendance by 11 percentage points, about half of which is attributable to attendance information. These treatments improve girls’ academic aspirations and reduce early marriage. Daily CCT set at a quarter of local child wage maximizes attendance impact. We highlight the importance of low-cost information technology to boost attendance sustainably and cost-effectively.

Implementation Of A Preconception Health Counseling Program, Emily J. Stidham

DNP Projects

Approximately 75 million women in the United States are of reproductive age, 15-44 years old. Among this group of childbearing-aged women, hypertension, diabetes, obesity, and other chronic health conditions are contributing to maternal morbidity, mortality, and poor infant outcomes (Raghuraman & Tuuli, 2021). The current unintended pregnancy rate in the United States is 48%, higher than the global rate of 41% (Ramos, 2019). To improve women’s health and perinatal outcomes, a shift in the paradigm of healthcare should focus on preventative care rather than reactive care. Preconception health counseling (PCHC) with the patient is a primary prevention strategy that allows …
