A lot of the adaptability of children's brains diminishes as they age. But researchers are looking for ways they might be able to restore some of that flexibility later in life.

With macrophages covered, let's move on to another innate immune cell type, dendritic cells. These are able to capture and present antigens to the T cells of the adaptive immune system, prompting a variety of outcomes. Let's take a look...

This is part one in a series of videos talking about managing ADHD symptoms with medication. Because ADHD can be thought of as a disorder of executive functioning so understanding this is an important lead in to making...

We've already begun examining some immunomodulating drugs, like the glucocorticoids, so let's zoom out for a more comprehensive view of this class. First let's check out immunosuppressants, drugs that suppress some unwanted or...

Biosignaling - Sonic Hedgehog (Shh) Signaling Pathway

In this video, we will discuss the precise mechanism by which the suprachiasmatic nucleus regulates melatonin release by the pineal gland.

Exercise Physiology | AMP, AMPK, & Energetic Stress

In this video, we will discuss the primary visual pathway, the neuronal connections between the optic nerve to the primary visual cortex.

Penicillin: Mechanism of Inhibition of Transpeptidase

Lesson on interactions between the Ras Raf MAPK and mTOR signaling pathways. Ras Raf MAPK and mTOR pathways have similar but distinct functions within the cell. During cell proliferation and growth, activation of these pathways is...

Nucleotide Metabolism | Regulation of Purine Biosynthesis

In this video, explore the biochemical mechanisms that promote bronchoconstriction and bronchodilation.

Here, we will see how two forms of arsenic, arsenate and arsenote, disrupt energy metabolism via glycolysis and the TCA cycle, respectively.

In this video, we explore the mechanisms of spasticity and baclofen, the major drug used in the treatment of spasticity. Also be sure to check out my video on the Modified Ashworth Scale!

In this video, we discuss the theory of the Kirby-Bauer Method for for qualifying antibiotic susceptibility. We also work through some examples.

In this video, we explore the concept of lateral inhibition, which is the process by which neighboring neurons in our brain pathway inhibit each other. This phenomenon enhances our visual system's ability to respond to edges of a...

Glycolysis and Gluconeogenesis Regulation 2

What to Avoid When Taking Statin Medications | Foods, Beverages and Medications that Increase Side Effects



Statin medications (ex. atorvastatin, rosuvastatin, simvastatin) are used to lower/reduce cholesterol levels. However,...

In this video, I talk about the process of lateral inhibition, and how it enhances visual edges. I do that by putting two rectangles next to each other. Watch this video to see what happens.

Irreversible Inhibition: A Mechanistic Approach

Everybody knows what allergies are, but what causes them? What drugs do we have available to address them? As we learned in the immunology series, allergies are symptoms of an immune response to a perceived threat. Histamine is a...

In this video, we will discuss the mechanisms of different types of biochemical inhibitors, how to interpret their Michaelis-Menten plots, and their effects on Vmax and Km of enzymes.

The video discusses the required practical activity for biology students to investigate the effects of antiseptics or antibiotics on bacterial growth using an Agar gel plate. The video begins by explaining the process of inoculating an...

We know that NSAIDs can inhibit both COX-1 and COX-2 enzymes. But these enzymes perform slightly different functions, and it seems that inhibition of COX-2 leads to the beneficial affects of NSAIDs while inhibition of COX-1 leads to the...
