Anatomy And Physiology Preparatory Course Textbook (2nd Edition), Carlos Liachovitzky

Open Educational Resources

The goal of this preparatory textbook is to give students a chance to become familiar with some terms and some basic concepts they will find later on in the Anatomy and Physiology course, especially during the first few weeks of the course.

Organization and functioning of the human organism are generally presented starting from the simplest building blocks, and then moving into levels of increasing complexity. This textbook follows the same presentation. It begins introducing the concept of homeostasis, then covers the chemical level, and later on a basic introduction to cellular level, organ level, and organ system level. This …

Retail Pharmacies And Drug Diversion During The Opioid Epidemic, Xuan Zhang, Aljoscha Janssen

Research Collection School Of Economics

This study investigates the role of retail pharmacy ownership in the opioid epidemic. Using data of prescription opioid orders, we show that compared with chain pharmacies, independent pharmacies dispense 39.1% more opioids and 60.5% more OxyContin. After an independent pharmacy becomes a chain pharmacy, opioid dispensing decreases. Using the OxyContin reformulation, which reduced non-medical demand but not the legitimate medical demand, we show that at least a third of the difference in the amount of OxyContin dispensed can be attributed to non-medical demand. We show that differences in competitive pressure and whether pharmacists own the pharmacy drive our estimates.

Human Anatomy And Physiology Preparatory Course, Carlos Liachovitzky

Open Educational Resources

The overall purpose of this preparatory course textbook is to help students familiarize with some terms and some basic concepts they will find later in the Human Anatomy and Physiology I course.

The organization and functioning of the human organism generally is discussed in terms of different levels of increasing complexity, from the smallest building blocks to the entire body. This Anatomy and Physiology preparatory course covers the foundations on the chemical level, and a basic introduction to cellular level, organ level, and organ system levels. There is also an introduction to homeostasis at the beginning.

Attention Deficit Hyperactivity Disorder, Cannabis Use, And The Endocannabinoid System: A Scoping Review, Brooke Worster, Jennie Ryan, Andrea Sparr-Jaswa, Mitchell Fruchtman

Department of Medicine Faculty Papers

There is emerging evidence that the endocannabinoid system (ECS) plays a significant role in the pathophysiology of many psychiatric disorders, including attention deficit hyperactivity disorder (ADHD). Increasing evidence suggests that a number of neurobiological correlates between endogenous cannabinoid function and cognitive dysfunction are seen in ADHD, making the ECS a possible target for therapeutic interventions. Cannabis use and cannabis use disorder are more prevalent in individuals with ADHD, compared to the general population, and there is growing popular perception that cannabis is therapeutic for ADHD. However, the relationship between cannabis use and ADHD symptomology is poorly understood. Further understanding of …

Current Analytical Techniques For Food Lipids, Cynthia Srigley

Food and Drug Administration Papers

Thee analysis of food lipids presents significant challenges due to the wide variety of sample matrices, large range of total fat contents, and complex compositions of fatty acids. This is chapter reviews conventional analytical techniques for the quantification of total fat and fatty acids in foods and food ingredients, including the gravimetric determination of total fat, the calculation of fat and fatty acids using gas chromatography (GC), and the analysis of proximates content (i.e., fat, protein, carbohydrate, moisture, and ash) by Fourier transform infrared (FTIR) spectroscopy. Current official methods of analysis are evaluated and the use of certified reference materials …

Cobenfy(Xanomeline/Trospium) Vs. Clozapine For Treatment-Resistant Schizophrenia, Kush Patel, Harmann Singh, Akash Patel, Abdullah Noory, Simran Gandhi

Rowan-Virtua Research Day

Background: Treatment-resistant schizophrenia (TRS) poses significant therapeutic challenges. Although clozapine remains the gold-standard pharmacologic treatment for TRS, its clinical utility is hampered by severe side effects and intensive monitoring requirements. KarXT (Cobenfy), a combination of xanomeline and trospium chloride, represents a novel antipsychotic approach by targeting muscarinic M1/M4 receptors instead of dopamine D2 pathways.

Hypothesis: KarXT offers comparable efficacy to clozapine with a more favorable safety and tolerability profile, making it a viable alternative for patients with TRS.

Methods: A systematic review was conducted to identify studies from 2015–2025 evaluating KarXT in schizophrenia. Sources included PubMed, ClinicalTrials.gov, FDA databases, ICER …

Robotripping: The Dangers Of Abusing Dextromethorphan

Stratford Campus Research Day

Dextromethorphan (3-methoxy-N-methylmorphinan), also known as “DXM,” is a synthetically produced drug available in many over-the- counter (OTC) cough and cold medications as a centrally acting cough suppressant that binds to NMDA receptors. In a 2006 national survey of 50,000 students, 4, 5, and 7% of 8, 10, and 12th graders reported DXM abuse in the past year. In high doses, DXM can cause euphoria, hallucinations, dissociations, and distortion of cognition and perception. DXM abuse is also known as “Robotripping,” “Robodosing,” “Dexing,” “Tussin,” or “Triple Cs” because Robitussin® and Coricidin® Cough and Cold are most frequently abused. DXM has replaced codeine …

Urolithin A, A Gut Metabolite, Improves Insulin Sensitivity Through Augmentation Of Mitochondrial Function And Biogenesis, Soonkyu Chung, Virginia Chaidez, Amanda Ramer-Tait, Ashley Toney, Ashley Toney

Nutrition and Health Sciences -- Faculty Publications

Objective: Urolithin A (UroA) is a major metabolite of ellagic acid produced following microbial catabolism in the gut. Emerging evidence has suggested that UroA modulates energy metabolism in various cells. However, UroA’s physiological functions related to obesity and insulin resistance remain unclear. Methods: Male mice were intraperitoneally administrated either UroA or dimethyl sulfoxide (vehicle) along with a high-fat diet for 12 weeks. Insulin sensitivity was evaluated via glucose and insulin tolerance tests and acute insulin signaling. The effects of UroA on hepatic triglyceride accumulation, adipocyte size, mitochondrial DNA content, and proinflammatory gene expressions were determined. The impact of UroA on …

Efficacy And Safety Of Bempedoic Acid In Patients With Hyperlipidemia And Non-Alcoholic Fatty Liver Disease, Amin Mehmoodi

Journal of Community Hospital Internal Medicine Perspectives

Hyperlipidemia and its association with cardiovascular diseases have been significant public health concerns for many decades. Statins have long been the primary therapeutic option for lowering cholesterol levels and reducing cardiovascular mortality. However, a substantial number of patients either do not achieve optimal lipid goals with maximally tolerated statin doses or experience statin intolerance. In recent years, there have been remarkable developments in the field of hyperlipidemia management, leading to the approval of novel hypolipidemic drugs in North America and Europe. This article reviews the clinical development of bempedoic acid, a promising new drug, alone and in combination with ezetimibe, …

Clearance Concepts: Fundamentals And Application To Pharmacokinetic Behavior Of Drugs, Reza Mehvar

Pharmacy Faculty Articles and Research

Clearance concepts were introduced into the pharmacokinetics discipline in the 1970s and since then have played a major role in characterization of the pharmacokinetic behavior of drugs. These concepts are based on the relationship between organ extraction ratio or clearance and physiologic parameters such as the organ blood flow and the intrinsic capability of the eliminating organ to remove the free (unbound) drug from the body. Several theoretical models have been developed, which define these relationships and may be used to predict the effects of changes in the physiological parameters on various pharmacokinetic parameters of drugs, such as drug clearance. …
