Explanation:
The treatment of ulceration in the foot of diabetic patients should initially be directed against their cause, specifically against pressure. The relief of plantar pressure can be achieved with bed rest and avoiding as much as possible supporting the foot.
In addition to pressure relief, the ulcer should be debrided regularly, with the removal of all callus and non-viable tissue formed around the ulcer. This facilitates the formation of a wound with healthy granulation tissue that heals from the base and not merely from the edges
In case of evidence of vascular insufficiency, the patient should be sent to a vascular surgeon for evaluation. This is particularly important in the absence of signs of healing after 6 weeks. X-rays should be performed to evaluate the foot early in the course of the ulcer and repeated if clinically indicated, due to lack of cure or presence of a deep infection, to detect an osteomyelitis disorder.
The usual attitude is to establish antibiotic treatment with the slightest clinical suspicion of infection. It is likely that the ulcer is colonized by multiple microorganisms, some of which are probably the real cause of an invasive infection, so the wound smears they usually provide little benefit Broad-spectrum antibiotics with aerobic and anaerobic coverage are required, including streptococci and staphylococci, such as amoxicillin-acidoclavulanic, clindamycin or ciprofloxacin (although the latter has poor antistaphylococcal coverage and limited antistareptococcal, penetrates tissues perfectly)
The population of frogs would exhibit competition due to the limited resources in the lake. Competition can be defined as the interaction among the species of organisms when resources are limited in an ecosystem. The type of competition observed in the above example of the lake with limited resources is called intraspecific competition as it is between the members of the same species competiting for the same resources. The species that do not compete will eventually die or get eliminated. This results in the change of population of frogs over time. Thus, competition is one among the forces that is responsible for natural selection.
Metastasis will happen and cancer cells invade nearby healthy cells, tissues, lymph nodes, organs or will migrate to distant organs.
The two different types of stem cells broadly classified as are Embryonic stem cells and adult stem cells. Embryonic stem cells are obtained from the blastocyst layer of the embryo and are pleuripotent. Whereas adult stem cells are the undifferentiated cells from tissues of an adult or a child. They can be unipotent or multipotent.
Explanation:
Cancer cells migrate to other parts of the body via blood and lymphatic system. This is called as metastasis. Cancer cells when becomes tumour they develop their own blood vessels and obtain nutrients from them. Once the tumour gets big it pushes the normal healthy cells of the neighbouring tissues and keeps on spreading.
Stem cells obtained from the embryo can differentiate into any types of cell and when grown in-vitro can dramatically form the three germ layers.
The adult embryo cells are found in less quantity, their role is to repair the tissue they reside in.
