How does cell proliferation affect the symptoms and the course of Zollinger-Ellison syndrome?

Jobisdone [24]3 years ago

Answer:

ascular endothelial cells are an established source of thrombospondin 1 (TSP1), a multifunctional extracellular matrix molecule. TSP1 appears to play an important role in modulating endothelial cell functions such as proliferation, migration, and capillary morphogenesis. In addition, TSP1 has recently been reported to potently inhibit angiogenesis both in vitro and in vivo. To better understand the mechanism underlying the antiangiogenic property of TSP1, endogenous TSP1 production was disrupted in bovine aortic endothelial cells (BAEC) by stable transfection with a vector expressing a TSP1 antisense RNA. Stable transfectants in which the antisense vector caused a decrease in TSP1 production were assayed for their ability to form capillary-like cords on gelled basement membrane matrix and for their responsiveness to the angiogenic/chemotactic mediator basic fibroblast growth factor. BAEC in which TSP1 production was disrupted exhibited a ten-fold increase over control BAEC in chemotactic activity to basic fibroblast growth factor and a twofold increase over control cells in the number of capillary-like cords that formed on gelled basement membrane matrix. Thus, the down-regulation of endogenous TSP1 appears to facilitate endothelial cell chemotaxis and capillary morphogenesis. These studies suggest that the modulation of TSP1 production is an important component of the angiogenic response, and support the idea that soluble TSP1 inhibits angiogenesis by interfering with endothelial cell chemotaxis and capillary formation.

How does asthma occur?​
julsineya [31]
Asthma is caused by swelling (inflammation) of the breathing tubes that carry air in and out of the lungs. This makes the tubes highly sensitive, so they temporarily narrow. It may happen randomly or after exposure to a trigger.

An ongoing clinical protocol at your site includes weekly blood draws to assess an exploratory endpoint. Unfortunately, participants are not happy about visiting the clinic weekly, and they are considering dropping out. Therefore, a protocol amendment is being prepared to remove the weekly blood draw. This change can be implemented once the protocol is finalised and submitted to the FDA.

<h3>What is the FDA?</h3>

The Federal Food and Drugs Act, which was passed in 1906, led to the creation of the Food and Drug Administration (FDA). The organisation is divided into divisions, each of which is in charge of the majority of the organisation's responsibilities relating to food, medicines, cosmetics, animal food, nutritional supplements, medical devices, biological products, and blood products.

The FDA is renowned for its efforts to control the creation of new medications. All new pharmaceuticals must undergo clinical trials, according to regulations set down by the FDA. Before medicines may be offered to humans, pharmaceutical companies must put them through four stages of clinical testing.

boyakko [2]

Answer:

Negative feedback.

Explanation:

Body's homeostasis is maintained by two feedback mechanism known as positive feedback and negative feedback. Most processes in our body is controlled by the negative feedback mechanism.

The negative feedback mechanism in which the final product of the reaction decreases the further secretion of that product. In case of the body temperature rise, brain canter decreases the body temperature is controlled by negative feedback. The high level of the substance decreases its further secretion in case of maintenance of body temperature.

Thus, the correct answer is option (c).
