Blood-ocular Barrier: Function, Role & Diseases

The blood-ocular barrier consists of the blood-retinal barrier as well as the blood-aqueous barrier and corresponds to a physiological barrier for defense against pathogens and maintenance of biochemically different milieus. Disorders of the blood-retinal barrier cause fluid accumulation in the retinal area, which can lead to retinal detachment. Most commonly, diabetes mellitus causes blood-ocular barrier … Blood-ocular Barrier: Function, Role & Diseases

Pulmonary Vascular Resistance: Function, Role & Diseases

Pulmonary vascular resistance (PVR) is the resistance to flow of blood vessels in the pulmonary circulation. It is also called pulmonary vascular resistance and is used to regulate blood flow. What is pulmonary vascular resistance? Pulmonary vascular resistance (PVR) is the resistance to flow of blood vessels in the pulmonary circulation. Pulmonary vascular resistance is … Pulmonary Vascular Resistance: Function, Role & Diseases

Angiogenesis: Function, Role & Diseases

The term angiogenesis encompasses all metabolic processes that involve the growth or new formation of blood vessels. Angiogenesis represents a complex process involving endothelial progenitor cells, smooth muscle cells, and pericytes. Promotion or inhibition of angiogenesis is increasingly used for therapeutic purposes-particularly in tumor therapy. What is angiogenesis? The term angiogenesis encompasses all metabolic processes … Angiogenesis: Function, Role & Diseases

Cartilage baldness – What is it?

Definition – What is cartilage baldness? The term cartilaginous baldness is derived from the traditional bald head and describes a condition in which the cartilage on the joint no longer completely covers the bone. In the joint, the bone is normally covered by cartilage, so the bone is not directly rubbed off during joint movements, … Cartilage baldness – What is it?

These are the symptoms of cartilage baldness | Cartilage baldness – What is it?

These are the symptoms of cartilage baldness Cartilage baldness is characterized by similar symptoms as other cartilage damage. Typically, pain occurs in the affected joint. These are particularly noticeable when the joint is subjected to stress. At rest, however, the symptoms are not as severe. In the course of the disease, the lack of a … These are the symptoms of cartilage baldness | Cartilage baldness – What is it?

Treatment of cartilage baldness | Cartilage baldness – What is it?

Treatment of cartilage baldness The therapy of cartilage baldness aims at allowing the cartilage to grow back over the bone. There are various methods for this. One can either try to cultivate cartilage cells from the body’s own stem cells. Alternatively, a foreign donation is also possible. These cells can usually be injected into the … Treatment of cartilage baldness | Cartilage baldness – What is it?

Transcytosis: Function, Role & Diseases

Transcytosis is a type of mass transfer in which a specific substance is taken up into the cell via endocytosis and released back into the extracellular space by exocytosis. Transcytosis is receptor-driven and occurs primarily in the epithelium of the intestine, at the blood–brain barrier, and in the placenta. The consequences of disruption of transcytosis … Transcytosis: Function, Role & Diseases

Membrane Transport: Function, Role & Diseases

In membrane transport, substances pass through a biological membrane or are actively transported through membranes. Unlike active transport, diffusion is the simplest membrane transport pathway and requires no additional provision of energy. Disorders of membrane transport are associated with a variety of different diseases. What is membrane transport? Membrane transport is when substances pass through … Membrane Transport: Function, Role & Diseases
