Microfracture is a minimally invasive procedure that effectively treats minor cartilage abnormalities in the near term. The ICRS-score is the most telling indicator of a decline in outcomes that begins 18 months following surgery. Young individuals with femoral condyle abnormalities had the highest prognostic odds.
How does microfracture work?
Because of their great efficacy, low cost, and short operating times when compared to other surgical methods, microfractures are frequently used as the first surgical option for the treatment of osteochondral lesions. Despite the patellofemoral compartment being the second most prevalent compartment for such lesions, the results of microfractures for retropatellar chondral abnormalities are mediocre when compared to other compartments of the knee. The patella's mobility, which is particularly noticeable when the patient's knee is extended, as is the situation in this kind of surgery, is one of the main causes of the inferiority.
Manual pressure has historically been used to overcome this hurdle, but this method is unreliable and prone to technical issues like skiving of the awl and restricted operating perspective, as well as consequences like fractures. This Technical Note describes a novel internal stabilization technique we call "house-on-stilts" that involves several Kirschner wire fixations into the patella and femur to immobilize the patella. This method supports both the debridement step before microfracturing without adding to operating costs or time.

What is the difference between Original Remains, and Trace Fossils? Give 3 examples of each
Answer:
Please find the difference below and their respective examples
Explanation:
Previously existing organisms leave behind evidences of their existence in form of remains that has been collected and mineralized called FOSSILS. However, the fossils of an organism (plant or animal) can either be a trace fossil or an original remain/body fossil. The difference between the two are as follows:
- An original remain is the fossilized body or body part of an organism that once existed. For example, bones, shells and fossilized leaf are examples of original remains.
- On the other hand, trace fossils refers to any form of evidence, apart from the organism's body, that suggests the presence of that organism in that particular place at a particular time. Trace fossils are said to be illustrate presence of life but indirectly (via their activities). Examples of trace fossils are burrows, tracks, marks etc.

detection and characterization of leptospira infection and exposure in rats on the caribbean island of saint kitts
Leptospirosis is a widespread zoonotic and potentially life-threatening disease in humans and animals.
Numerous animal species keep Leptospira, the bacterium that causes this sickness, in their kidneys and excrete it in their urine. These creatures are a source of pollution for the environment and illness. Rats are an important reservoir host of the disease and have previously been reported to have Leptospira infection in the Caribbean island of Saint Kitts. However, there is presently no information on rats. The major objective of this study was to use a complementary set of diagnostic methods to identify Leptospira infection and exposure in two kinds of rats on Saint Kitts. Then, using a mix of serologic, molecular, and genomic methods, infecting Leptospira strains were described.

What is structurally different between starch and cellulose that gives them different physical properties?.
Although Cellulose are macromolecules belonging to the same group of carbohydrates, but cellulose is a polysaccharide that has beta 1,4 linkages between glucose monomers while the starch is a polysaccharide that has alpha 1,4 linkages between glucose monomers.
What is Cellulose?Cellulose is the polymeric chains of glucose monomers linked together by beta 1,4 glycoside linkages, t is the most abundant organic molecule which is a structural unit of plants.
Cotton and paper are the examples of cellulose containing product which comprises about 4000-8000 glucose molecules with beta bonds between the 1st C of the first unit and the 4th carbon of the next glucose unit.

What are the features of cell division?
Cell division is the process by which a parent cell divides into two daughter cells. Cell division usually occurs as part of a larger cell cycle in which the cell grows and replicates its chromosome before dividing.
Moreover, these phases are prophase, prometaphase, metaphase, anaphase, and telophase. Cytokinesis is the final physical cell division that follows telophase, and is therefore sometimes considered a sixth phase of mitosis.
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells.

Do you believe that environmental factors have shaped human characteristics. If so in what ways?
Answer:
Yes
Explanation:
Environmental factors caused many different traits in people, for instance the different skin pigments of people depend on where their ancestors came from. European descendents tend to absorb more sunlight and get sunburned easily, whereas African descendents have skin that is suitable for their environment. Other characteristics include immunity to malaria or the speed at which one's blood can carry oxygen. These traits came slowly through natural selection as people evolved to become suited for their environment.
