Internet Journal of Allied Health Sciences and Practice

Background: Tinnitus can be defined as a health condition characterized by the perception of sound, either in the head and/or ears, in the absence of any external acoustic stimulus. Perception is often quantified by self-report, or the use of patient reported outcome measures (PROMs). The purpose of this rapid review was to evaluate the level and quality of evidence regarding the use of serotonin and norepinephrine reuptake inhibitors (SNRI), selective serotonin reuptake inhibitors (SSRI), and tricyclic antidepressants as measured by tinnitus patient-reported outcome measures (PROMs) and/or Visual Analog Scales (VAS). Methods: The Cochrane Rapid Review guidelines were followed. The PICO …

The Therapeutic Potential Of Targeting Cardiac Rgs4., Giselle Del Calvo, Teresa Baggio Lopez, Anastasios Lymperopoulos

HPD Articles

G protein-coupled receptors (GPCRs) play pivotal roles in regulation of cardiac function and homeostasis. To function properly, every cell needs these receptors to be stimulated only when a specific extracellular stimulus is present, and to be silenced the moment that stimulus is removed. The regulator of G protein signaling (RGS) proteins are crucial for the latter to occur at the cell membrane, where the GPCR normally resides. Perturbations in both activation and termination of G protein signaling underlie numerous heart pathologies. Although more than 30 mammalian RGS proteins have been identified, each RGS protein seems to interact only with a …

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 …

Cardiac Rgs Proteins In Human Heart Failure And Atrial Fibrillation: Focus On Rgs4., Jordana I. Borges, Malka S. Suster, Anastasios Lymperopoulos

HPD Articles

The regulator of G protein signaling (RGS) proteins are crucial for the termination of G protein signals elicited by G protein-coupled receptors (GPCRs). This superfamily of cell membrane receptors, by far the largest and most versatile in mammals, including humans, play pivotal roles in the regulation of cardiac function and homeostasis. Perturbations in both the activation and termination of their G protein-mediated signaling underlie numerous heart pathologies, including heart failure (HF) and atrial fibrillation (AFib). Therefore, RGS proteins play important roles in the pathophysiology of these two devasting cardiac diseases, and several of them could be targeted therapeutically. Although close …

In Vitro Dissolution And Permeability Testing Of Inhalation Products: Challenges And Advances., Ali Nokhodchi, Salonee Chavan, Taravat Ghafourian

HPD Articles

In vitro dissolution and permeability testing aid the simulation of the in vivo behavior of inhalation drug products. Although the regulatory bodies have specific guidelines for the dissolution of orally administered dosage forms (e.g., tablets and capsules), this is not the case for orally inhaled formulations, as there is no commonly accepted test for assessing their dissolution pattern. Up until a few years ago, there was no consensus that assessing the dissolution of orally inhaled drugs is a key factor in the assessment of orally inhaled products. With the advancement of research in the field of dissolution methods for orally …

Narrative Review: The Fda’S Perfunctory Approach Of Dietary Supplement Regulations Giving Rise To Copious Reports Of Adverse Events, Weiqi Li, Albert Wertheimer

Comparative Evaluation Of Biased Agonists Sarcosine , D-Alanine -Angiotensin (Ang) Ii (Sd Ang Ii) And Sarcosine , Isoleucine -Ang Ii (Si Ang Ii) And Their Radioiodinated Congeners Binding To Rat Liver Membrane At Receptors, Natalia M. Noto, Yazmin M. Restrepo, Hong W. Pang, Filipe Stoyell-Conti, Crystal A. West, Robert C. Speth, Nova Southeastern University

HPD Articles

Angiotensin II analogue and β-arrestin biased agonist TRV027 (Sarcosine , d-Alanine -Angiotensin (Ang) II; SD Ang II), developed by Trevena, Inc. in the early 2010s, brought hopes of a novel treatment for cardiovascular diseases, due to its ability to simultaneously cause signaling through the β-arrestin signaling pathway, while antagonizing the pathophysiological effects of Ang II mediated by the AT receptor G protein signaling cascades. However, a phase II clinical trial of this agent revealed no significant benefit compared to placebo treatment. Using I-Sarcosine , Isoleucine -Ang II ( I-SI Ang II) radioligand receptor competition binding assays, we assessed the relative …

Hippocampal Versus Cortical Deletion Of Cholinergic Receptor Muscarinic 1 In Mice Differentially Affects Post-Translational Modifications And Supramolecular Assembly Of Respiratory Chain-Associated Proteins, Mitochondrial Ultrastructure, And Respiration: Implications In Alzheimer's Disease, Mohammad Golam Sabbir, Mamiko Swanson, Robert C. Speth, Benedict C. Albensi

HPD Articles

In a previous retrospective study using postmortem human brain tissues, we demonstrated that loss of Cholinergic Receptor Muscarinic 1 (CHRM1) in the temporal cortex of a subset of Alzheimer's patients was associated with poor survival, whereas similar loss in the hippocampus showed no such association. Mitochondrial dysfunction underlies Alzheimer's pathogenesis. Therefore, to investigate the mechanistic basis of our findings, we evaluated cortical mitochondrial phenotypes in Chrm1 knockout (Chrm1) mice. Cortical Chrm1 loss resulted in reduced respiration, reduced supramolecular assembly of respiratory protein complexes, and caused mitochondrial ultrastructural abnormalities. These mouse-based findings mechanistically linked cortical CHRM1 loss with poor survival of …

Why Angiotensin Ii Is A Poor Choice For Circulatory Support Of Ventilated Covid-19 Patients Compared To Vasopressin, Robert C. Speth, Michael Bader

HPD Articles

Early in the COVID-19 pandemic when it was first reported that SARS-CoV-2 used membrane-bound angiotensin-converting enzyme-2 (ACE2) as its receptor for entry into cells, warnings were raised against the use of angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) because of their potential to increase ACE2 expression. These reports ignored the adverse effects that the renin-angiotensin system (RAS) exerts on the cardiovascular system and kidneys via its primary hormone angiotensin (Ang) II acting upon AT receptors that could exacerbate the cytokine storm induced by SARS-CoV-2 . At one point it was even recommended that COVID-19 patients suffering from cardiovascular …
