The question of how a vaccination would work to combat the current COVID-19 pandemic is a major concern right now. Everybody has their own perspective on the situation, and in some people’s minds, vaccines do not fit into the equation. Therefore, it’s extremely important to understand what a vaccine’s purpose is, how it is supposed to achieve that purpose, how a vaccine is developed, and its benefits versus side effects before coming to a final conclusion on the subject as it relates to the pandemic. To understand a vaccination’s purpose it is necessary to first understand how a pathogen works. A pathogen is essentially any foreign material (foreign in the sense that it is not a part of the human body), that can cause disease or a malfunction of the body. They spread from surface to surface and person to person.

Microfilaments and microtubules are both important elements of the cytoskeleton, maintaining the structure and integrity of the cell, but there are several differences between microfilaments and microtubules. In this article, we share this information on microfilaments versus microtubules.
Microfilament and Microtubulues are made from different individual subunits. Microfilaments are made from ACTIN, while microtubules are made from TUBULIN.
Making up around 75% of all animal species in the world, arthropods are are a vast phylum of the kingdom Animalia. The name comes from the Greek words “arthro”, meaning joint, and “podos”, meaning legs. While they all share segmented bodies with joined legs, members in this phylum vary wildly, from butterflies and millipedes, to scorpions and lobsters. They are also all invertebrates, which means that they do not have backbones. Instead, they use hard exoskeletons to protect themselves, which are made out of chitin. Because these exoskeletons are relatively inflexible, arthropods molt as they grow larger, which means they shed their exoskeletons.
Acid Deposition (commonly known as Acid Rain) means precipitation that has acidic components, i.e. an unusually low pH level (4.2~4.4). Acid rain is a term coined in 1852 by Robert Angus Smith, a Scottish scientist who conducted rainwater experiments in industrial regions throughout Scotland and England.
In this quick easy-to-understand lesson, we learn about atrial fibrillation, causes, symptoms, diagnoses, and treatments for USMLE medicine. Atrial fibrillation is the most common type of cardiac arrhythmia. This means the heart beat has an irregularly irregular rhythm. Symptoms can include fatigue, dyspnea (difficulty breathing), and heart palpitations in the chest. You diagnose atrial fibrillation via EKG. It can be treated with medications or surgically.
Water quenches thirst, is crucial when taking a bath, and is important when cooking. Yet despite the fact that it is all around us and used in our daily lives, there are many facts and health benefits about water that remain unknown to many people.
Innate vs Adaptive Immunity: What are the differences between innate and adaptive immunity? The human body has two protective immunological systems against pathogens: the innate immunity and the adaptive immunity. In this quick and easy lesson, we will explain the differences between the innate and adaptive immunity. The innate immunity and adaptive immunity differ based on the type of components that are used to protect the human body. For example, the innate immunity consists of neutrophils, dendritic cells, natural killer cells, macrophages, complements, physical barriers. On the other hand, the adaptive immunity contains components such as T cells, B cells, and antibodies to protect us from viruses, bacteria, and other pathogens.
The heart’s function is to consistently move the blood in the body for the blood to spread nutrients to other body parts or to be replenished with oxygen and nutrients from other respective organs. The heartbeat is a way to understand the pace at which the blood is moving and how quick the heart is pumping itself. A heartbeat changes based on its environment. Running and high-intensity movement causes the heart to increase its number of beats whereas resting may lead to a lower heartbeat for the low amount activity that does not require as much oxygen. Depending on the difficulty and intensity of each activity, the heart accommodates via changing its pace to fit the body’s needs. In certain cases, however, a cardiac arrhythmia occurs and can lead to different cardiac issues that may or may not be harmless. Cardiac arrhythmia has affected millions of people in a multitude of forms. This article explains the basics of this condition such as heart block and bradycardia. The article is solely for educational purposes and not to diagnosis. What is a Cardiac Arrhythmia?

Vitamins and minerals both help our bodies work properly, and they aid with functions such as growth and development. So what is the difference between the two? Simply stated, vitamins are organic and minerals are inorganic. This means that vitamins come from living sources, like plants and animals, while minerals come from elsewhere, such as the earth. Vitamins tend to have more complex structures than minerals, and because of this, are more prone to degradation via heat or chemicals. Today, we will be focusing on vitamins.
The coronavirus pandemic may seem like one of the worst things that could be happening to the world right now.

It is widely known that the elderly and the immunocompromised are at the highest risk of being severely impacted by COVID-19, a virus that targets the lungs and respiratory system. The younger demographic, including teenagers, are not generally considered as being threatened by this disease. Even if teenagers do contract the virus, it is assumed that they will only experience mild symptoms and will recover quickly. However, vaping, an activity especially popular among teenagers, may increase their vulnerability to COVID-19. COVID-19 and vaping are similar threats in that not much is known about either of them, but both are recognized as possibly life-threatening. The safest choice to make in this time of uncertainty is to avoid anything that may cause the situation to be more dangerous, and until more information surfaces, that includes vaping.
