In patients with Diabetes, whose endogenous production of insulin is completely or near to nothing, insulin is administered to them subcutaneously.
The insulin is usually bovine insulin or pork insulin. Recently, human insulins have been manufactured by rDNA technology. These preparations are called exogenous insulins.
Bacterial cells are commonly used in biotechnology to produce insulin using exogenous DNA. The exogenous DNA encoding for human insulin is introduced into the bacterial cells, which then serve as a host to produce the insulin protein through the process of genetic engineering.
Exogenous is the use of something from outside the organism - such as insulin. A link with a longer definition is below.
Endogenous insulin is insulin that is produced by the pancreas in response to glucose levels in the body. It plays a crucial role in regulating blood sugar levels by facilitating the uptake of glucose from the blood into cells for energy production. People with diabetes may require exogenous insulin, which is insulin introduced from an outside source, to help manage their blood sugar levels.
I am a future pharmacy student, so ATM my knowledge is quite limited. However, if i had to guess i would guess the reasoning behind taking metaformin WITH insulin is because the use of exogenous insulin causes your body's insulin receptors to downregulate. Metaformin, on the other hand, causes these same receptors to upregulate. Doing this will prevent you from becoming insulin resistance and possibly requiring more insulin eventually for the same effects. Also do not think metaformin is just an oral insulin, IT IS NOT!. They both lower blood sugar levels, but in different mays. Do not get them confused!!! I hope i helped :)
Exogenous behavior is the behavior that is derived externally and outside the body. Exogenous behavior can also be in reference to outside sources that effect us, such as temperature and sunlight.
Insulin levels can be increased by taking exogenous insulin as a medication injected under the skin and absorbed into the bloodstream. Insulin deficiency usually occurs in Type 1 (juvenile) diabetes that starts at a young age (children, teens, young adults). Type 2 diabetics (onset in adulthood) usually have high insulin levels, but the insulin does not work effectively to get sugar to move from the blood into the cells. These people need to increase the effectiveness of the insulin they produce at the cell level, and there are medications (oral) that can help with this. The overall need for insulin can be reduced by reducing sugars in the diet and reducing one's body weight. Exercise helps insulin be utilized more effectively as well.
exogenous pathogens.
Exogenous infection is a bacterial infection that develops from the outside of the body. Exogenous bacteria are foodborne and waterborne which can be consumed directly or through secondary host.
I believe, exogenous virus exist as: "replication competent viruses that are transmitted horizontally in mice, while endogenous viruses exist as germline sequences that are usually not replication competent by may recombine with exogenous viruses during the course of infection." This would refer to exogenous retroviruses.
The endogenous variables value is established by the conditions of the other variables in the structure. The exogenous variables value in independent of the conditions of the other variables in the structure. The difference between the endogenous and exogenous variables is the endogenous depends solely on the structure and the exogenous depend on outside elements.
true
The term exogenous means something relating to external factors. It is used in biology to refer to something that is growing or originating from outside of an organism.
