Nanoparticle Approaches For The Renin-Angiotensin System, Sajini D. Hettiarachchi, Young M. Kwon, Yadollah Omidi, Robert C. Speth

HPD Articles

The renin-angiotensin system (RAS) is a hormonal cascade that contributes to several disorders: systemic hypertension, heart failure, kidney disease, and neurodegenerative disease. Activation of the RAS can promote inflammation and fibrosis. Drugs that target the RAS can be classified into 3 categories, AT1 angiotensin receptor blockers (ARBs), angiotensin-converting enzyme (ACE) inhibitors, and renin inhibitors. The therapeutic efficacy of current RAS-inhibiting drugs is limited by poor penetration across the blood-brain barrier, low bioavailability, and to some extent, short half-lives. Nanoparticle-mediated drug delivery systems (DDSs) are possible emerging alternatives to overcome such limitations. Nanoparticles are ideally 1-100 nm in size and are …

AIMS: There are no comprehensive machine learning (ML) tools used by oncologists to assist with risk identification and referrals to cardio-oncology. This study applies ML algorithms to identify oncology patients at risk for cardiovascular disease for referrals to cardio-oncology and to generate risk scores to support quality of care.

METHODS AND RESULTS: De-identified patient data were obtained from Vanderbilt University Medical Center. Patients with breast, kidney, and B-cell lymphoma cancers were targeted. Additionally, the study included patients who received immunotherapy drugs for treatment of melanoma, lung cancer, or kidney cancer. Random forest (RF) and artificial neural network (ANN) ML models …

Ace2/Ang1-7 Mas Axis: The Counter-Regulator Of The Classical Renin Angiotensin System, Widelyne Dorsainval

Mako: NSU Undergraduate Student Journal

To maintain homeostasis, the renin-angiotensin system (RAS) works to regulate the cardiovascular, renal, respiratory, and neurological systems of the body. However, there is evidence that abundant amounts of certain components of the RAS have detrimental effects and enhance disease. Recent studies have proved that there is a lesser known RAS which acts to counterbalance the classical RAS. To better understand their interaction, the effects of the alternate RAS against the classical RAS in the homeostatic systems of the body are researched and analyzed. The classical pathway employs these components: angiotensin converting enzyme (ACE), angiotensin II (AngII), and angiotensin II type …

Lose To Win: Fighting Obesity In The Workplace, Latoya Dotson

Student Theses, Dissertations and Capstones

Background: Obesity is a significant healthcare problem in modern American society. It has led to decreased longevity of employees and decreased productivity in day-to-day duties of healthcare workers. There are more negative attributes to obesity than positive, regardless of the race affected. One of the leading causes of death in 2012 was cardiovascular disease. Due to poor dietary choices, the promotion of sedentary lifestyle has led to complications of obesity such as high blood pressure and diabetes. Major improvements can be made within a community that acknowledges the risks of obesity and seeks to implement preventive programs. Increasing one’s physical …
