Cultivating Grit: Faculty Influence On Females' Academic Success In Engineering Majors, Lisa Lynn Wymer

Theses and Dissertations

The purpose of this study was to identify the relationships between the positive and negative factors that impact undergraduate female engineering students’ academic success in their programs. While females participate and persist in higher education at higher rates than their male counterparts, engineering is one field of study where gender disparity remains especially apparent, as males continue to outnumber females in engineering degree attainment (Ross, Kena, Rathbun, KewalRamani, Zhang, Kristapovich, & Manning, 2012, Schreuders, Mannon, & Rutherford, 2009, Tsui, 2009). The conceptual framework for this study was based on Tinto’s Longitudinal Model of Institutional Departure, which provides the theoretical foundation …

Canadian Children From Food Insecure Households Experience Low Self-Esteem And Self-Efficacy For Healthy Lifestyle Choices, Stephanie L. Godrich, Olivia K. Loewen, Rosanne Blanchet, Noreen Willows, Paul Veugelers

Research outputs 2014 to 2021

The objectives of this cross-sectional study were to: (i) determine whether there are differences in self-esteem and self-efficacy for healthy lifestyle choices between children living in food secure and food insecure households; and (ii) determine whether the association between household food insecurity (HFI), self-esteem and self-efficacy differs by gender. Survey responses of 5281 fifth-grade students (10 and 11 years of age) participating in the Canadian Children's Lifestyle and School Performance Study II were analyzed using logistic and linear regression. HFI status was determined by the six-item short-form Household Food Security Survey Module (HFSSM). Students from food insecure households had significantly …

Factors Associated With Condom Use With Non-Commercial Partners Among Sexually-Active Transgender Women In Cambodia: Findings From A National Survey Using Respondent-Driven Sampling., Siyan Yi, Amelia Plant, Sovannary Tuot, Phalkun Mun, Srean Chhim, Navy Chann, Pheak Chhoun, Carinne M. Brody

BACKGROUND: Globally, the prevalence of HIV among transgender women is much higher than that of the general adult population. This can be explained by the persistently low rate of consistent condom use among this population. This study was therefore conducted to explore factors associated with consistent condom use among sexually-active transgender women in Cambodia, specifically with their non-commercial partners.

METHODS: Data used for this study were collected as part of the National Integrated Biological and Behavioral Survey 2016. Participants were recruited from the capital city of Phnom Penh and 12 other provinces with high burden of HIV using the Respondent-Driven …

Sparse profiling of CpG methylation in blood by microarrays has identified epigenetic links to common diseases. Here we apply methylC-capture sequencing (MCC-Seq) in a clinical population of ~200 adipose tissue and matched blood samples (Ntotal~400), providing high-resolution methylation profiling (>1.3 M CpGs) at regulatory elements. We link methylation to cardiometabolic risk through associations to circulating plasma lipid levels and identify lipid-associated CpGs with unique localization patterns in regulatory elements. We show distinct features of tissue-specific versus tissue-independent lipid-linked regulatory regions by contrasting with parallel assessments in ~800 independent adipose tissue and blood samples from the general population. We follow-up …

A failure in optic fissure fusion during development can lead to blinding malformations of the eye. Here, we report a syndrome characterized by facial dysmorphism, colobomatous microphthalmia, ptosis and syndactyly with or without nephropathy, associated with homozygous frameshift mutations in FAT1. We show that Fat1 knockout mice and zebrafish embryos homozygous for truncating fat1a mutations exhibit completely penetrant coloboma, recapitulating the most consistent developmental defect observed in affected individuals. In human retinal pigment epithelium (RPE) cells, the primary site for the fusion of optic fissure margins, FAT1 is localized at earliest cell-cell junctions, consistent with a role in facilitating optic …

Why Are Seemingly Satisfied Female Lawyers Running For The Exits? Resolving The Paradox Using National Data, Joni Hersch, Erin E. Meyers

Marquette Law Review

Despite the fact that women are leaving the practice of law at alarmingly high rates, most previous research finds no evidence of gender differences in job satisfaction among lawyers. This Article uses nationally representative data from the 2015 National Survey of College Graduates to examine gender differences in lawyers’ job satisfaction, and finds that any apparent similarity of job satisfaction between genders likely arises from dissatisfied female JDs sorting out of the legal profession at higher rates than their male counterparts, leaving behind the most satisfied women. This Article also provides a detailed examination of the specific working conditions that …

Insulin Resistance And Chronic Kidney Disease Progression, Cardiovascular Events, And Death: Findings From The Chronic Renal Insufficiency Cohort Study, Sarah J Schrauben, Patricia Kao, Et Al

Open Access Publications

BACKGROUND: Insulin resistance contributes to the metabolic syndrome, which is associated with the development of kidney disease. However, it is unclear if insulin resistance independently contributes to an increased risk of chronic kidney disease (CKD) progression or CKD complications. Additionally, predisposing factors responsible for insulin resistance in the absence of diabetes in CKD are not well described. This study aimed to describe factors associated with insulin resistance and characterize the relationship of insulin resistance to CKD progression, cardiovascular events and death among a cohort of non-diabetics with CKD.

METHODS: Data was utilized from Chronic Renal Insufficiency Cohort Study participants without …

White Matter Damage, Neuroinflammation, And Neuronal Integrity In Hand, Aljoharah Alakkas, David B Clifford, Et Al.

2010-2019 OA Pubs

HIV-associated neurocognitive disorders (HANDs) persist even with virologic suppression on combination antiretroviral therapy (cART), and the underlying pathophysiological mechanisms are not well understood. We performed structural magnetic resonance imaging and MR spectroscopy (MRS) in HIV+ individuals without major neurocognitive comorbidities. Study participants were classified as neurocognitively unimpaired (NU), asymptomatic (ANI), mild neurocognitive disorder (MND), or HIV-associated dementia (HAD). Using structural MRI, we measured volumes of cortical and subcortical gray matter and total and abnormal white matter (aWM). Using single-voxel MRS, we estimated metabolites in frontal gray matter (FGM) and frontal white matter (FWM) and basal ganglia (BG) regions. Adjusted odds …

A person's lipid profile is influenced by genetic variants and alcohol consumption, but the contribution of interactions between these exposures has not been studied. We therefore incorporated gene-alcohol interactions into a multiancestry genome-wide association study of levels of high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglycerides. We included 45 studies in stage 1 (genome-wide discovery) and 66 studies in stage 2 (focused follow-up), for a total of 394,584 individuals from 5 ancestry groups. Analyses covered the period July 2014-November 2017. Genetic main effects and interaction effects were jointly assessed by means of a 2-degrees-of-freedom (df) test, and a 1-df test …

Elbow Angle Modulates Corticospinal Excitability To The Resting Biceps Brachii At Both Spinal And Supraspinal Levels, Siobhan C. Dongés, Janet L. Taylor, James L. Nuzzo

Research outputs 2014 to 2021

NEW FINDINGS:

What is the central question of this study?

Corticospinal excitability to biceps brachii is known to modulate according to upper-limb posture. Here, cervicomedullary stimulation was used to investigate potential spinal contributions to elbow angle-dependent changes in corticospinal excitability at rest.

What is the main finding and its importance?

At more extended elbow angles, biceps responses to cervicomedullary stimulation were decreased, whereas cortically evoked responses (normalized to cervicomedullary-evoked responses) were increased. Results suggest decreased spinal excitability but increased cortical excitability as the elbow is placed in a more extended position, an effect that is unlikely to be attributable to …

Background: Clostridium difficile-associated diarrhea (CDAD) is common during hematopoietic stem-cell transplantation (HSCT) and is associated with increased morbidity and mortality. We evaluated fidaxomicin for prevention of CDAD in HSCT patients.

Methods: In this double-blind study, subjects undergoing HSCT with fluoroquinolone prophylaxis stratified by transplant type (autologous/allogeneic) were randomized to once-daily oral fidaxomicin (200 mg) or a matching placebo. Dosing began within 2 days of starting conditioning or fluoroquinolone prophylaxis and continued until 7 days after neutrophil engraftment or completion of fluoroquinolone prophylaxis/clinically-indicated antimicrobials for up to 40 days. The primary endpoint was CDAD incidence through 30 days after study medication. …

Reward Improves Response Inhibition By Enhancing Attentional Capture, Yanqing Wang, Todd S Braver, Shouhang Yin, Xueping Hu, Xiangpeng Wang, Antao Chen

2010-2019 OA Pubs

Reward plays a crucial role in enhancing response inhibition. While it is generally assumed that the process of response inhibition involves attentional capture and the stopping of action, it is unclear whether this reflects a direct impact of reward on response inhibition or rather an indirect mediation via attentional capture. Here, we employed a revised stop-signal task (SST) that separated these two cognitive elements, by including a continue signal that required the same motor response as in go trials, but also attention to a cue, as in stop trials. We first confirmed the engagement of the right inferior frontal gyrus …

Understanding The Role Of Cognitive Behavioral Therapy Among Women With Fibromyalgia: A Review Of The Literature, Emily Hall

All Electronic Theses and Dissertations

Background: Women with fibromyalgia (FM) experience a range of symptoms threatening the integrity of their overall wellbeing. Since no cure exists, management to reduce symptoms, disability, and improve functionality is the focus. Promising outcomes have been demonstrated when cognitive behavioral therapy (CBT) is used as a complementary measure to other treatments to increase an individual’s coping mechanisms through various exercises. Purpose: The Theory of Unpleasant Symptoms (TOUS), introduced by Elizabeth Lens and colleagues in 1995, provided a guiding framework to evaluate the effectiveness of multidisciplinary therapy with CBT in controlling influencers of pain and general symptom intensity. Results: Nineteen studies …

Congenital anomalies of the kidney and urinary tract (CAKUT) are a major cause of pediatric kidney failure. We performed a genome-wide analysis of copy number variants (CNVs) in 2,824 cases and 21,498 controls. Affected individuals carried a significant burden of rare exonic (that is, affecting coding regions) CNVs and were enriched for known genomic disorders (GD). Kidney anomaly (KA) cases were most enriched for exonic CNVs, encompassing GD-CNVs and novel deletions; obstructive uropathy (OU) had a lower CNV burden and an intermediate prevalence of GD-CNVs; and vesicoureteral reflux (VUR) had the fewest GD-CNVs but was enriched for novel exonic CNVs, …

Rab proteins play an essential role in regulating intracellular membrane trafficking processes. Rab activity is dependent upon geranylgeranylation, a post-translational modification that involves the addition of 20-carbon isoprenoid chains via the enzyme geranylgeranyl transferase (GGTase) II. We have focused on the development of inhibitors against geranylgeranyl diphosphate synthase (GGDPS), which generates the isoprenoid donor (GGPP), as anti-Rab agents. Pancreatic ductal adenocarcinoma (PDAC) is characterized by abnormal mucin production and these mucins play important roles in tumor development, metastasis and chemo-resistance. We hypothesized that GGDPS inhibitor (GGDPSi) treatment would induce PDAC cell death by disrupting mucin trafficking, thereby inducing the unfolded …

The Divergent Effects Of Cdppb And Cannabidiol On Fear Extinction And Anxiety In A Predator Scent Stress Model Of Ptsd In Rats, John Shallcross, Peter Hámor, Allison R. Bechard, Madison Romano, Lori Knackstedt, Marek Schwendt

Psychology

Post-traumatic stress disorder (PTSD) currently has no FDA-approved treatments that reduce symptoms in the majority of patients. The ability to extinguish fear memory associations is impaired in PTSD individuals. As such, the development of extinction-enhancing pharmacological agents to be used in combination with exposure therapies may benefit the treatment of PTSD. Both mGlu5 and CB1 receptors have been implicated in contextual fear extinction. Thus, here we tested the ability of the mGlu5 positive allosteric modulator 3-Cyano-N-(1,3-diphenyl-1H-pyrazol-5-yl)benzamide (CDPPB) and cannabidiol (CBD) to reduce both conditioned and unconditioned fear. We used a predator-threat animal model of PTSD which we and others have …

BACKGROUND: Community-acquired pneumonia (CAP) is a major global disease. Parapneumonic effusions often complicate CAP and range from uninfected (simple) to infected (complicated) parapneumonic effusions and empyema (pus). CAP patients who have a pleural effusion at presentation are more likely to require hospitalization, have a longer length of stay and higher mortality than those without an effusion. Conventional management of pleural infection, with antibiotics and chest tube drainage, fails in about 30% of cases. Several randomized controlled trials (RCT) have evaluated the use of corticosteroids in CAP and demonstrated some potential benefits. Importantly, steroid use in pneumonia has an acceptable safety …

Acute myeloid leukemia (AML) with an internal tandem duplication in Fms-related tyrosine kinase 3 (FLT3-ITD) is identified as a subgroup with poor outcome and intrinsic resistance to chemotherapy and therefore urgent need for development of novel therapeutic strategies.

Methods: The antitumor effects of melatonin alone or combined with sorafenib were evaluated via flow cytometry and immunoblotting assays in FLT-ITD AML cells. Also, the ex vivo and in vivo models were used to test the synergistic effects of melatonin and sorafenib against leukemia with FLT3/ITD mutation.

Results: Our study shows for the first time that melatonin inhibits proliferation and induces apoptosis …
