Baltic Journal of Health and Physical Activity

Background: This study aimed to investigate the relationships between age, experience, anthropometric measures, physical fitness, and the quality of technical performance in karate practitioners. We conducted an observational cross-sectional study with 53 federated karate athletes, aged 5 to 55, affiliated with the Youth Karate Association Portugal. The participants were divided into age and experience groups to assess differences in anthropometric measures (body mass, height, BMI) and physical fitness (strength, power, flexibility). The technical performance of four specific karate techniques – kizami, gyaku zuki, mawashi geri, and ura mawashi geri – was evaluated using a custom-designed technical evaluation …

"I Know Who I Am": Draw-And-Tell Conversations With Gender-Creative Children, Eline Leemans Lenne

Dissertations and Theses

A growing number of children identify in various gender-creative ways, likely due to broader social awareness and affirmation of transgenderism. Gender-creative children face higher risks for adverse social, academic, mental health, and healthcare outcomes compared to non-transgender peers. Support from loved ones along with guidance from pediatric providers can mitigate poor outcomes and ensure that gender-creative children live healthy and happy lives. Young gender-creative children's perspectives about the aforementioned topics are markedly absent from the literature, which instead highlights adolescent and adult proxy perspectives.

In this participatory arts-based study anchored by a constructivist epistemology and informed by post-structuralist, queer, and …

Clear cell renal cell carcinoma (ccRCC), despite having a low mutational burden, is considered immunogenic because it occasionally undergoes spontaneous regressions and often responds to immunotherapies. The signature lesion in ccRCC is inactivation of the VHL tumor suppressor gene and consequent upregulation of the HIF transcription factor. An earlier case report described a ccRCC patient who was cured by an allogeneic stem cell transplant and later found to have donor-derived T cells that recognized a ccRCC-specific peptide encoded by a HIF-responsive endogenous retrovirus (ERV), ERVE-4. We report that ERVE-4 is one of many ERVs that are induced by HIF, translated …

Most human transcription factor (TF) genes encode multiple protein isoforms differing in DNA-binding domains, effector domains, or other protein regions. The global extent to which this results in functional differences between isoforms remains unknown. Here, we systematically compared 693 isoforms of 246 TF genes, assessing DNA binding, protein binding, transcriptional activation, subcellular localization, and condensate formation. Relative to reference isoforms, two-thirds of alternative TF isoforms exhibit differences in one or more molecular activities, which often could not be predicted from sequence. We observed two primary categories of alternative TF isoforms: "rewirers" and "negative regulators," both of which were associated with …

Breaking The Synaptic Vesicle Cycle: Mechanistic Insights Into Presynaptic Dysfunctions In Epilepsy, Kevin Jiang, Lu-Tang Yang, Mingshan Xue

Duncan NRI Faculty and Staff Publications

Synaptic dysfunction is a hallmark of many neurological disorders including epilepsy. An increasing number of epilepsy-causing pathogenic variants are being identified in genes encoding presynaptic proteins that affect every step of the synaptic vesicle cycle, from vesicle loading, tethering, docking, priming, calcium sensing, fusing, to recycling. These different molecular dysfunctions result in converging impairment of presynaptic neurotransmitter release, yet lead to diverse epileptic disorders. This review focuses on representative monogenic epileptic disorders caused by pathogenic variants of key presynaptic proteins involved in different stages of the synaptic vesicle cycle: SYN1 (vesicle pool regulation), STXBP1 (vesicle docking, priming, and fusion), and …

We have developed a family of biology-based mathematical models of high-grade glioma (HGG), capturing the key features of tumour growth and response to chemoradiation. We now seek to quantify the accuracy of parameter estimation and determine, when given a virtual patient cohort, which model was used to generate the tumours. In this way, we systematically test both the parameter and model identifiability. Virtual patients are generated from unique growth parameters whose growth dynamics are determined by the model family. We then assessed the ability to recover model parameters and select the model used to generate the tumour. We then evaluated …

Conformal Predictive Intervals In Survival Analysis: A Resampling Approach, Jing Qin, Jin Piao, Jing Ning, Yu Shen

Faculty, Staff and Student Publications

The distribution-free method of conformal prediction has gained considerable attention in computer science, machine learning, and statistics. Candès et al. extended this method to right-censored survival data, addressing right-censoring complexity by creating a covariate shift setting, extracting a subcohort of subjects with censoring times exceeding a fixed threshold. Their approach only estimates the lower prediction bound for type I censoring, where all subjects have available censoring times regardless of their failure status. In medical applications, we often encounter more general right-censored data, observing only the minimum of failure time and censoring time. Subjects with observed failure times have unavailable censoring …

Computational Sensitivity Evaluation Of Ultrasound Neuromodulation Resolution To Brain Tissue Sound Speed With Robust Beamforming, Boqiang Fan, Wayne Goodman, Sameer A Sheth, Richard R Bouchard, Behnaam Aazhang

Faculty, Staff and Student Publications

Low-intensity focused ultrasound (LIFU) neuromodulation requires precise targeting and high resolution enabled by phased array transducers and beamforming. However, focusing optimization usually relies on phantom measurements or simulations with inaccurate acoustic properties to degrade neuromodulation resolution. Therefore, this work analyzes the sensitivity of neuromodulation resolution, measured by off-target activation area (OTAA), to brain tissue sound speed. A Robust Optimal Resolution (ROR) beamforming method is proposed to minimize the worst-case OTAA with restricted sound speed inaccuracy and propagation information estimated with deviated sound speed. The propagation estimation model utilizes equivalent source method (ESM) to map sound field between different acoustic parameter …

The Role Of Non-Statin Lipid Lowering Therapies To Reduce Ascvd Events In Primary Prevention, Chukwuemezie Mamanu, Dean Karalis

Division of Cardiology Faculty Papers

PURPOSE OF REVIEW: Atherosclerotic cardiovascular disease (ASCVD) remains a leading global health challenge, with low-density lipoprotein (LDL) cholesterol a pivotal risk factor. While statins are cornerstone therapy for lowering LDL cholesterol, many high-risk primary prevention patients are unable to tolerate statin therapy and do not achieve their guideline directed LDL cholesterol goal. For these patients, non-statin therapies offer complementary and alternative approaches to LDL cholesterol reduction.

RECENT FINDINGS: Recent advancements in non-statin therapies have expanded the options available to clinicians to lower LDL cholesterol in high-risk primary prevention patients. Yet these medications are often under-utilized in clinical practice. Observational studies, …

Natural killer T cells (NKTs) are a promising platform for cancer immunotherapy, but few genes involved in the regulation of NKT therapeutic activity have been identified. To find regulators of NKT functional fitness, we developed a CRISPR/Cas9-based mutagenesis screen that uses a guide RNA (gRNA) library targeting 1,118 immune-related genes. Unmodified NKTs and NKTs expressing a GD2-specific chimeric antigen receptor (GD2.CAR) were transduced with the gRNA library and exposed to CD1d+ leukemia or CD1d-GD2+ neuroblastoma cells, respectively, over six challenge cycles in vitro. Quantification of gRNA abundance revealed enrichment of PRDM1-specific gRNAs in both NKTs and GD2.CAR NKTs, a result …

Age-Associated Proteins Explain The Role Of Medial Temporal Lobe Networks In Alzheimer’S Disease, Adam Turnbull, Yejin Kim, Kai Zhang, Xiaoqian Jiang, Zihuai He, Victor W Henderson, F Vankee Lin

Faculty, Staff and Student Publications

The structural connectivity (SC) of the medial temporal lobe and its associated cortical anterior temporal and posterior medial networks (MTL-AT-PM) is linked to pathologies and memory decline in Alzheimer's disease (AD). However, neuroimaging analyses cannot tell us how SC changes occur in AD at the molecular level and do not provide a means of intervening to slow/prevent pathology-related changes in MTL-AT-PM SC. The current study aimed to understand how and where AD-related changes occur within MTL-AT-PM using proteomics. We used a 4-step approach in 101 older adults from a local sample, aiming to understand how proteins and SC in combination …

Music And Word Learning In Children Diagnosed With Developmental Language Disorder, Rebekah G. Sweeney

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Purpose: This study investigates whether incorporating music into vocabulary interventions improves rate of learning and retention of words in children with developmental language disorder (DLD). Emerging literature continues to show the plentiful benefits of music as a tool for intervention in many settings, including the world of speech pathology (Levitin, 2024). However, it is also evident that there is a connection between struggling with language, and struggling with musical elements, such as rhythm and pitch perception, particularly in children with DLD (Boorom et al., 2022; Kreidler et al., 2023). This study seeks to tease out if music is an effective …

Uterus didelphys refers to a congenital uterine anomaly that occurs due to failed fusion of the paired Müllerian ducts. It is characterized by two separate noncommunicating uterine horns each with its cervix and fallopian tube. Duplication may be limited to the uterus, cervix or also involve the vagina. Here, we present a case of a 27-year-old primigravida incidentally diagnosed during pregnancy, followed up with cervical cerclage at 13 weeks due to a short cervix and had preterm delivery via cesarean section at 35 weeks. She had a successful pregnancy outcome and an uneventful postnatal course. Uterus didelphys is associated with …

The Effect Of A M-Health Application Compared To Standard Of Care On Adherence To Preoperative Fasting Instructions Among Adult Patients Undergoing Elective Surgery: A Randomized Controlled Study, Ivy Njeri Wanyoike

Master of Medicine in Anaesthesiology

Background: Preoperative fasting has been a pillar of the practice of anaesthesiology with the main aim of enhancing patient safety by reducing the risk of aspiration. Current clinical guidelines on preoperative fasting guidelines encourage shorter durations of fasting in keeping with current evidence that shows better patient outcomes while maintaining patient safety. Despite this, adherence to preoperative fasting instructions remains universally poor, with patients enduring long fasting periods. Advances in mobile technology, improving internet access and the widespread availability of smartphones have made mobile health a useful tool in patient care. mHealth applications are being increasingly used in perioperative …

17β-oestradiol (E2) inhibits overeating and promotes brown adipose tissue (BAT) thermogenesis, whereas prolactin (PRL) does the opposite. During lactation, the simultaneous decline in E2 and surge in PRL contribute to maternal metabolic adaptations, including hyperphagia and suppressed BAT thermogenesis. However, the underlying neuroendocrine mechanisms remain unclear. Here, we find that oestrogen receptor alpha (ERα)-expressing neurons in the medial basal hypothalamus (MBH), specifically the arcuate nucleus of the hypothalamus and the ventrolateral subdivision of the ventromedial hypothalamus (vlVMH), are suppressed during lactation. Deletion of ERα from MBH neurons in virgin female mice induces metabolic phenotypes characteristic of lactation, including hyperprolactinemia, hyperphagia …

The Impact Of Hyperglycemia On Post-Reperfusion Outcomes In Patients With Hyperacute Ischemic Stroke, Nicole Schumacher

Theses and Dissertations (ETD)

Stroke is a major contributor to disability in the United States, with ischemic stroke accounting for approximately 87% of all cases. The use of approved reperfusion therapies, including intravenous thrombolysis with tissue plasminogen activator (tPA) and mechanical thrombectomy, has significantly improved functional outcomes for ischemic stroke patients. However, hyperglycemia at the time of hospital arrival is associated with worse outcomes, including increased infarct growth, higher rates of disability, and elevated mortality. Despite this, current stroke guidelines neither exclude hyperglycemic patients from receiving reperfusion therapy nor recommend glucose management during the hyperacute phase of care. While recent studies suggest that mild …

Idiopathic pulmonary fibrosis (IPF) is a disease with a poor prognosis and no curative therapies. Fibroblast activation by transforming growth factor β1 (TGFβ1) and disrupted metabolic pathways, including the arginine-polyamine pathway, play crucial roles in IPF development. Polyamines are agonists of the calcium/cation-sensing receptor (CaSR), activation of which is detrimental for asthma and pulmonary hypertension, but its role in IPF is unknown. To address this question, we evaluated polyamine abundance using metabolomic analysis of IPF patient saliva. Furthermore, we examined CaSR functional expression in human lung fibroblasts (HLFs), assessed the anti-fibrotic effects of a CaSR antagonist, NPS2143, in TGFβ1-activated normal …
