Mitral stenosis (MS) is narrowing of the mitral valve. In the normal cardiac cycle, the heart relaxes during diastole and allows blood to flow from the left atrium to the left ventricle through the open mitral valve. When the mitral valve is narrowed, blood flow becomes restricted (Figure 1). Excess volume and pressure build up…Listen »
A macrovascular complication of diabetes, diabetic nephropathy is progressive, chronic kidney disease seen in patients with both type 1 and type 2 diabetes mellitus, usually after at least 10 years of hyperglycemia (high blood glucose levels). The three main lesions that are seen in the kidney in patients with diabetes are glomerular lesions, vascular lesions,…Listen »
Differences in ion concentrations inside and outside a cell cause a difference in the charge of the intracellular and extracellular environments. This electrical polarization of a cell relative to its environment is referred to as cellular membrane potential. This potential serves as an energy source for a variety of cellular functions and as a way…Listen »
You might have heard the term opiates. These are drugs like morphine, codeine, and thebaine that are found naturally in the opium poppy plant. Synthetic drugs like fentanyl and methadone that target the same receptors but are not found in the opium poppy are referred to as opioids. Opioids that are created by chemically modifying…Listen »
Welcome to the fascinating world of cell wall synthesis inhibitors, where we will venture into the realm of one of the most clinically used antibiotics, the penicillins. They are broad-spectrum antibiotics, meaning they attack more than one species of bacteria. We’ll explore each drug, its mechanism of action, its side effects, and so on. Penicillin…Listen »
In 1959, the first case of immunodeficiency virus to infect a human was documented in Kinshasa, Democratic Republic of the Congo. Scientists would go on to theorize that the man contracted what became known as HIV-1 from a West African chimpanzee infected with simian immunodeficiency virus (SIV), probably from coming into contact with the chimp’s…Listen »
On inspiration, a healthy set of lungs is pulled outward by the negative pressure created by the increase in chest volume. On expiration, the lungs recoil inward due to their elastic properties. Simply put, the lung is easily stretched outward but shrinks inward when it is no longer being pulled by external forces. Obstructive lung…Listen »
Hypertension, or high blood pressure, affects about a third of adults, making it a very prevalent condition. Having high blood pressure is generally an asymptomatic silent condition, unless it’s very severe. Without symptoms, the condition is likely to go undetected and thus untreated. Coupling untreated hypertension with pregnancy can lead to disastrous outcomes for both…Listen »
If you are just starting out with musculoskeletal anatomy, the terminology might make your head spin. What are all the directions, terms, and obscure muscles and structures? The goal of this discussion is to clue you into the anatomy vocabulary you need to survive the study of the many muscles and bones you will encounter…Listen »
Sickle cell disease affects millions of people worldwide, causing debilitating pain, infection, organ failure, stroke, and premature death. Although the mortality rate has decreased over the past 20 years, a staggering 90% of children with sickle cell disease in resource-poor countries do not survive to adulthood. As improbable as it might seem, given the scope…Listen »
