Introduction. E-cigarettes (e-cigs) have been shown to be pro-arrhythmic in both human and male rodent studies; however, little is known about how e-cig use impacts patients with a predisposed heightened risk for arrhythmias, including pregnant women. Both pregnancy and e-cig use have independently been shown to increase heart rate, diminish heart rate variability, and increase ventricular premature beats, which is suspected to be due to sympathetic dominance. Importantly, β-blockers have been shown to reduce sympathetic activity, reduce heart rate, increase HRV, and reduce arrhythmias. Thus, the use of β-blockers may help prevent adverse health effects driven by sympathetic dominance from …

Graduate Theses and Dissertations
The Atlantic killifish (Fundulus Heteroclitus) is a teleost found in brackish water estuaries, which are subject to large fluctuations in salinity, that handles osmotic stress by triggering compensatory actions across their osmoregulatory organs. As the external salinity increases, the killifish intestine exhibits a high degree of phenotypic plasticity, as the protein composition of the gut epithelium can be modified to absorb desalinated water (H2O) from ingested seawater (SW). Three osmoregulatory hormones, prolactin (P), growth hormone (GH), and cortisol (F), have been observed to be crucial for these transitions to occur in many species of teleosts, including killifish. This research sought …

Peripheral Artery Disease (PAD) affects an estimated 200 million people worldwide and is the leading cause of amputation in the United States. PAD is characterized by atherosclerotic narrowing of arteries, resulting in ischemia from reduced blood flow to distal tissues. Although surgical and percutaneous interventions can restore perfusion, fewer than 50% of patients experience sustained benefit, highlighting the need for alternative therapeutic strategies. One promising approach is promoting arteriogenesis, the growth and outward remodeling of pre-existing collateral vessels that improve blood flow around the occluded arteries. Arteriogenesis is regulated by regenerative, M2-polarized macrophages, making macrophage polarization a key therapeutic target. …

An officer’s motivation (desire to exercise) and self-efficacy (belief in ability to exercise) could affect whether they exercise and predict resulting fitness. Data from 60 officers (48 men, 12 women) were analyzed. Motivation (amotivation, external, introjected, identified, integrated, and intrinsic regulation) was measured via the Behavioral Regulation in Exercise Questionnaire. A 6-item questionnaire assessed coping (confidence in exercising under challenging conditions) and scheduling (confidence in scheduling exercise) self-efficacy. General fitness variables included sit-and-reach, grip strength, 60-s push-ups, 60-s sit-ups, …

The Role Of Inflammatory Cytokines In The Bidirectional Relationship Between Periodontitis And Diabetes Mellitus, Andrew R. Witty
Oral Health
Periodontitis and type 2 diabetes mellitus are associated with each other in a bidirectional relationship. The mechanism by which diabetes affects periodontitis is understood to be due to the inflammatory effects of hyperglycemia (high blood glucose levels) and a hospitable environment for sugar-consuming bacteria. Periodontitis is known to be associated with higher levels of glycated hemoglobin (HbA1c), a long-term measurement of blood glucose control, and treatment of periodontitis reduces HbA1c. Inflammation caused by periodontitis induces insulin resistance (which leads to higher blood glucose levels), but due to the complex nature of inflammation it is difficult to …

This study aimed to apply a multi-visit Step–Ramp–Step (SRS) protocol to identify aerobic (VT1) and anaerobic (VT2/RCP) thresholds in trained endurance runners, with a particular focus on delineating the isocapnic buffering region—the ventilatory phase between VT1 and VT2 where carbon dioxide (PetCO₂) remains stable despite rising ventilation. Twelve trained male runners (mean age: 27.1 ± 1.9 years; VO₂max: 60.5 ± 2.1 ml·kg⁻¹·min⁻¹) completed the SRS protocol across separate lab visits. Each session included a 4-minute moderate-intensity phase, a progressive …

The effectiveness of time-efficient high-intensity interval training (HIIT) in reducing VAT has not been reviewed. A systematic search conducted on PubMed, Embase, and SPORTDiscus up to April 2025 for randomized controlled trials that compared HIIT with non-exercise control and quantified VAT using imaging identified five trials (n = 138) that met inclusion criteria. Risk of bias was assessed using a nine-item modified PEDro scale. Four trials reported significant reductions in VAT after 8-12 weeks of …

Therefore, the purpose of this study was to investigate caffeine’s effects on measures of PWR alone and following an acute bout of RE in young, healthy, resistance-trained women. Eleven resistance-trained women completed an acute bout of RE using free-weights with repetitions to failure for squat and bench press with caffeine (4mg/kg) and a placebo. Measures of PWR were measured at Rest, 50 minutes following ingestion …
