By injecting Mesenchymal Stem Cells with ability to express high amount of Akt or protein kinase B in myocardium, researchers witnessed restored cardiac function and inhibition of ventricular remodeling. The effect was seen after two weeks of administration of cells. The culture containing hypoxic Akt-MSCs (conditioned medium) inhibits apoptosis or cell death induced due to hypoxia. Also, it triggers in vitro contraction of cardiomyocytes, the cardiac cells specifically responsible for contraction function.
The desired functional improvement can occur in short time which is less than 72 hours, the reason for which was hypothesized as paracrine action of cells. Hypothesis was proved by upregulation of genes that code for factors responsible for above mentioned effects (apoptosis and contraction). The factors are FGF-2, VEGF, HGF etc.

It is important to ask about the reactions caused by an insect bite because this will allow you to act quickly if there are health effects.
<h3>What is an insect sting?</h3>
The insect sting is the way in which insects defend themselves when they feel attacked by other organisms. Insects generally have stingers or spikes on their bodies to defend themselves against predators.
<h3>Why is it important to be aware of the effects of a sting?</h3>
When a person suffers a sting, it is necessary to report all the symptoms that they experience because some insects have substances that affect the body and can cause allergic reactions that put the health and life of the individual at risk.

Answer:
Answer is A. Profuse bleeding.
Explanation:
The acute response can be described as an early or immediate response of the tissue to injury. It is always for a short period of time.
Acute inflammation involves some processes which are initiated in order to limit damage to tissues.
The acute inflammatory process include pain, redness, immobility, swelling and heat.
In this case, profuse bleeding is the only one that is not part of the processes.
Therefore, the young man will not experience profuse bleeding.
<span>In the nfpa 704 labeling system, a rating of 4 in any quadrant corresponds to t</span>he highest degree of hazard. Hazard
severity is indicated by a numerical rating that ranges from zero (0)
indicating a minimal hazard, to four (4) indicating a severe hazard.
