Biochemical And Biophysical Properties Of Failing Myocardium In Rare Patient Populations, Gregory Nathaniel Milburn

Theses and Dissertations--Physiology

Heart failure has diverse underlying etiologies, complicating research. While some types, like ischemic disease or inherited mutations, are well-studied, research on rarer forms has lagged. Understanding the molecular drivers in these populations may enhance diagnostics and therapies. This work examines two rare groups: patients with ATTR cardiac amyloidosis and those receiving mechanical assist device support. We show that myocardium from patients with amyloidosis has increased fibrosis and reduced force production without changes in cross-bridge kinetics. Additionally, we show that the passive stiffness of amyloidosis myocardium is not different from non-failing myocardium, indicating increased ventricular wall thickness may cause restrictive filling. …

Biochemical Properties Of Cardiac Sarcomeres In Human Heart Failure, Austin Grey Wellette-Hunsucker

Theses and Dissertations--Physiology

Heart failure (HF) exhibits considerable heterogeneity, posing significant challenges for research involving human cohorts. Diastolic dysfunction is a common pathophysiological feature; however, its molecular mechanisms remain incompletely elucidated. Sarcomeric proteins are integral to cardiac contraction and relaxation. Nonetheless, the phosphoproteome and the structural remodeling effects of these proteins on diastolic function within the context of HF have not been comprehensively characterized. This study examined sarcomeric modifications in diastolic dysfunction in human HF, focusing on Dilated and Ischemic HF, with non-failing donor hearts as controls. Analyzing myocardial samples from ~150 patients using electrophoretic and biochemical techniques, it found significant titin remodeling …

The Incidence Of Postmenopausal Breast Cancer In Relation To Occupational Exposure To Textile Fibers And Dusts In Montreal, Canada, 2008-2011, Maymouna Myriam Ka, France Labrèche, Mark S. Goldberg, Vikki Ho

Études primaires

Objective To estimate the associations between occupational exposure to textile fibers/dusts, and incidence of postmenopausal invasive breast cancer.

Methods

A population-based case-control study conducted in Montreal (2008 − 2011) identified hospital cases (N = 695) and population controls (N = 608) from the electoral list. Occupational hygienists examined participants’ occupations and tasks, and attributed exposures to several textile fibers. For all tumors and according to biomolecular subtypes, odds ratios (OR) and 95% confidence intervals (95%CI) were estimated using logistic regression models with different exposure indices, adjusting for potential confounders.

Results

Ever exposure to cotton dust was associated with an increased …

Occupational Exposure To Combustion By-Products And Breast Cancer Risk In Postmenopausal Women, Kahlila Paul-Cole, France Labrèche, Mark S. Goldberg, Sydney Westra, Vikki Ho

Études primaires

Objective

To estimate the association between lifetime occupational exposure to select combustion by-products and postmenopausal breast cancer (BC) risk.

Materials and Methods

Data from a population-based case-control study among postmenopausal women residing in Montréal, Quebec were used. Cases included 661 women aged between 47 and 75 yr, diagnosed with incident malignant BC between 2008 and 2011. Controls comprised 587 women randomly selected from the Quebec Electoral List, frequency-matched to cases by 5-year age groups. Information on risk factors and lifetime occupational histories was collected by interview. Two industrial hygienists used job histories to assign exposure to 293 agents, including 6 …

Fabricating Silver-Ceria Polymer Nanocomposite Scaffolds For Biomedical Therapeutic Applications, Shreya S. Pawar

Honors Undergraduate Theses

Improper healing of bone fractures and limited regeneration of bone following bone tumor resection remain a prevalent complication worldwide. Long-term effects of this include joint instability, limited movement, and arthritis. Bone infections (osteomyelitis), reactive oxygen species (ROS) generation via excessive inflammation, and underlying conditions such as osteoporosis can contribute to suboptimal bone tissue regeneration. ROS accumulation stimulates osteoblast apoptosis, while promoting osteoclast differentiation. These processes inhibit mineralization and osteogenesis. Conventional therapeutics involve the utilization of drugs and bone grafts. However, these approaches pose limitations and can result in subsequent complications. Microbial infections, ROS accumulation, and excessive inflammations are factors that …

Management of bleeding in persons with hemophilia and inhibitors involves treatment with bypassing agents, including recombinant activated factor VII (rFVIIa). Two rFVIIa products are commercially approved for use in the United States and the European Union. Eptacog alfa and eptacog beta share the same amino acid sequence but differ in posttranslational modifications. Although rFVIIa has been used to manage bleeding in persons with hemophilia and inhibitors for over 30 years, its mechanisms of action is still being studied. In vitro and in vivo studies have suggested that rFVIIa could promote hemostasis by (1) increasing tissue factor-dependent activation of factor (F)X …

Diabetes Device Knowledge And Confidence Among School Nurses: A Mixed Methods Study, Cassandra F. Moffitt

Nursing Theses and Dissertations

Problem: Type 1 diabetes is one of the most common chronic medical conditions in childhood. While manageable, these children may spend half of their day in the school setting and often need assistance from a school nurse to manage their care.

Theory: Bandura’s Social Cognitive Theory (1977) served as the theoretical framework for this study.

Research Questions: The research questions explored knowledge, confidence, and additional predictors of confidence related to diabetes devices.

Design/Methods: An explanatory sequential mixed methods design was used. The Diabetes Device Confidence Scale (DDCS) was used to measure device confidence, while Subscale 10 of the KAT-1 instrument …
