Developmental Patterning Of Peptide Transcription In The Central Circadian Clock In Both Sexes, Vania Carmona-Alcocer, Lindsey S. Brown, Aisha Anchan, Kayla E. Rohr, Jennifer A. Evans Jan 2023

Developmental Patterning Of Peptide Transcription In The Central Circadian Clock In Both Sexes, Vania Carmona-Alcocer, Lindsey S. Brown, Aisha Anchan, Kayla E. Rohr, Jennifer A. Evans

Biomedical Sciences Faculty Research and Publications

Introduction: Neuropeptide signaling modulates the function of central clock neurons in the suprachiasmatic nucleus (SCN) during development and adulthood. Arginine vasopressin (AVP) and vasoactive intestinal peptide (VIP) are expressed early in SCN development, but the precise timing of transcriptional onset has been difficult to establish due to age-related changes in the rhythmic expression of each peptide.

Methods: To provide insight into spatial patterning of peptide transcription during SCN development, we used a transgenic approach to define the onset of Avp and Vip transcription. Avp-Cre or Vip-Cre males were crossed to Ai9+/+ females, producing offspring in which the fluorescent protein …

Trichomonas vaginalis is responsible for 156 million new cases per year worldwide. When present asymptomatically, the parasite can lead to serious complications, such as development of cervical and prostate cancer. As infection increases the acquisition and transmission of HIV, the control of trichomoniasis represents an important niche for the discovery and development of new antiparasitic molecules. This urogenital parasite synthesizes several molecules that allow the establishment and pathogenesis of infection. Among them, peptidases occupy key roles as virulence factors, and the inhibition of these enzymes has become an important mechanism for modulating pathogenesis. Based on these premises, our group recently …


Meeting The Client Halfway: A Relational Revision To Account For Intra-Actions In Psychotherapeutic Space, Lara Pirro Jancetic Jan 2023

Meeting The Client Halfway: A Relational Revision To Account For Intra-Actions In Psychotherapeutic Space, Lara Pirro Jancetic

Antioch University Dissertations & Theses

This post-qualitative study branching from new-materialist, post-humanist epistemology and ontology examines relationality through the lens of three different theories: agential realism, John Shotter’s communication theory, and relational mindfulness. These theories each describe the dynamics involved in relationships, how they each make sense of these dynamics, and what they entail for human relations. Using a post-qualitative diffractive methodology, this study examines these theories and how they intersect to bring about new insights in our understanding of relationships and how this information can support therapy practice. The results are a series of nine principles of orientation, which were applied to marriage and …

Relationship Goals: How Do Relational Therapists Conceptualize Cases And Treatment Plan When Working With Consensually Non-Monogamous Clients?, Caitlyn Burns

Antioch University Dissertations & Theses

This study aimed to explore how relational therapists in the United States conceptualize cases and treatment plan when working with consensually non-monogamous clients and how dominant discourses about relationships (mononormativity) influence relational therapists during this process through a queer theory lens. This was a grounded theory study and surveyed a sample of thirty relational therapists or therapists-in- training. Results showed relational therapists conduct conceptualization and treatment planning through a two-part process. Therapists intend to treat CNM clients the same as any other client, but are unable to do so due to dominant discourses of mononormativity. Furthermore, mononormative discourses influenced relational …

Counselors’ Lived Experience Treating Patients Utilizing Methadone: The Intersection Of Culture, Policy, And Stigma, Kathryn Floyd Eggert Jan 2023

Counselors’ Lived Experience Treating Patients Utilizing Methadone: The Intersection Of Culture, Policy, And Stigma, Kathryn Floyd Eggert

Antioch University Dissertations & Theses

The United States continues to experience unprecedented deaths related to the opioid epidemic. Efforts to address the epidemic remain hampered by war-on-drugs policies that stigmatize people who use drugs and create barriers to accessing evidence-based treatments, particularly methadone maintenance treatments (MMT). Despite 50 years of research regarding MMT, it remains highly regulated, and arguably the most stigmatized treatment. The punitive regulatory structure of MMT remained unchanged until emergency waivers were initiated during the COVID-19 pandemic. The study used an exploratory, critical phenomenological approach to examine the intersection of culture and regulation on the lived experiences of 26 addiction counselors who …

Research outputs 2022 to 2026

Background

Circulating tumour cells (CTCs) are attractive “liquid biopsy” candidates that could provide insights into the different phenotypes of tumours present within a patient. The epithelial-to-mesenchymal transition (EMT) of CTCs is considered a critical step in tumour metastasis; however, it may confound traditional epithelial feature-based CTC isolation and detection. We applied single-cell copy number alteration (CNA) analysis for the identification of genomic alterations to confirm the neoplastic nature of circulating cells with only mesenchymal phenotypes.

Methods

We isolated CTCs from blood samples collected from 46 NSCLC patients using the Parsortix system. Enriched cells were subjected to immunofluorescent staining for CTC …

Identifying The Serious Clinical Outcomes Of Adverse Reactions To Drugs By A Multi-Task Deep Learning Framework, Haochen Zhao, Peng Ni, Qichang Zhao, Xiao Liang, Di Ai, Shannon Erhardt, Jun Wang, Yaohang Li, Jiianxin Wang

Computer Science Faculty Publications

Adverse Drug Reactions (ADRs) have a direct impact on human health. As continuous pharmacovigilance and drug monitoring prove to be costly and time-consuming, computational methods have emerged as promising alternatives. However, most existing computational methods primarily focus on predicting whether or not the drug is associated with an adverse reaction and do not consider the core issue of drug benefit-risk assessment-whether the treatment outcome is serious when adverse drug reactions occur. To this end, we categorize serious clinical outcomes caused by adverse reactions to drugs into seven distinct classes and present a deep learning framework, so-called GCAP, for predicting the …

Cellbrf: A Feature Selection Method For Single-Cell Clustering Using Cell Balance And Random Forest, Yunpei Xu, Hong-Dong Li, Cui-Xiang Lin, Ruiqing Zheng, Yaohang Li, Jinhui Xu, Jianxin Wang

Computer Science Faculty Publications

Motivation

Single-cell RNA sequencing (scRNA-seq) offers a powerful tool to dissect the complexity of biological tissues through cell sub-population identification in combination with clustering approaches. Feature selection is a critical step for improving the accuracy and interpretability of single-cell clustering. Existing feature selection methods underutilize the discriminatory potential of genes across distinct cell types. We hypothesize that incorporating such information could further boost the performance of single cell clustering. Results

We develop CellBRF, a feature selection method that considers genes’ relevance to cell types for single-cell clustering. The key idea is to identify genes that are most important for discriminating …

The Impact Of Acute Calcium Intake On Bone Turnover Markers During A Training Day In Elite Male Rowers, Bronwen Lundy, Alannah K. A. Mckay, Nikita C. Fensham, Fensham, Nicolin Tee, Bryce Anderson, Aimee Morabito, Megan L. R. Ross, Marc Sim, Kathryn Ackerman, Louise M. Burke

Research outputs 2022 to 2026

Introduction: While an acute exercise session typically increases bone turnover markers (BTM), the impact of subsequent sessions and the interaction with pre-exercise calcium intake remains unclear despite the application to the ‘real life’ training of many competitive athletes. Methods: Using a randomized crossover design, elite male rowers (n = 16) completed two trials, a week apart, consisting of two 90-minute rowing ergometer sessions (Ex1, Ex2) separated by 150 minutes. Prior to each trial, participants consumed a high (CAL: ~1000 mg) or isocaloric low (CON: < 10 mg) calcium meal. Biochemical markers including parathyroid hormone: PTH; serum ionised calcium (iCa) and bone turnover markers (C-terminal telopeptide of type I collagen: β-CTX-I; osteocalcin: OC) were monitored from baseline to 3 hours post Ex2. Results: While each session caused perturbances of serum iCa, CAL maintained calcium concentrations above those of CON for most time points, 4.5 and 2.4 % higher post EX1 and EX2 respectively. The decrease in iCa in CON was associated with an elevation of blood PTH (p < 0.05) and β-CTX-I (p < 0.0001) over this period of repeated training sessions and their recovery, particularly during and after Ex2. Pre-exercise intake of calcium-rich foods lowered BTM over the course of a day with several training sessions. Conclusions: Pre-exercise intake of a calcium-rich meal prior to training sessions undertaken within the same day had a cumulative and prolonged effect on the stabilisation of blood iCa during exercise. In turn, this reduced the post-exercise PTH response, potentially attenuating the increase in markers of bone resorption. Such practical strategies may be integrated into the athlete’s overall sports nutrition plan, with the potential to safeguard long term bone health and reduce the risk of bone stress injuries.

Computer Science Faculty Publications

Motivation: Cancer heterogeneity drastically affects cancer therapeutic outcomes. Predicting drug response in vitro is expected to help formulate personalized therapy regimens. In recent years, several computational models based on machine learning and deep learning have been proposed to predict drug response in vitro. However, most of these methods capture drug features based on a single drug description (e.g. drug structure), without considering the relationships between drugs and biological entities (e.g. target, diseases, and side effects). Moreover, most of these methods collect features separately for drugs and cell lines but fail to consider the pairwise interactions between drugs and cell …

An Approach To Developing Benchmark Datasets For Protein Secondary Structure Segmentation From Cryo-Em Density Maps, Thu Nguyen, Yongcheng Mu, Jiangwen Sun, Jing He

Computer Science Faculty Publications

More and more deep learning approaches have been proposed to segment secondary structures from cryo-electron density maps at medium resolution range (5--10Å). Although the deep learning approaches show great potential, only a few small experimental data sets have been used to test the approaches. There is limited understanding about potential factors, in data, that affect the performance of segmentation. We propose an approach to generate data sets with desired specifications in three potential factors - the protein sequence identity, structural contents, and data quality. The approach was implemented and has generated a test set and various training sets to study …

Here, we present a protocol to isolate progenitor cells from mouse epididymal visceral adipose tissue and construct bulk RNA and assay for transposase-accessible chromatin with sequencing (ATAC-seq) libraries. We describe steps for adipose tissue collection, cell isolation, and cell staining and sorting. We then detail procedures for both ATAC-seq and RNA sequencing library construction. This protocol can also be applied to other tissues and cell types directly or with minor modifications.

For complete details on the use and execution of this protocol, please refer to Liu et al. (2023).1
