Fiber Laser Marking

One more biology question?

The spindle fibers of a dividing cell were labeled with a flourecent dye. At the beginning of anaphase, a laser beam was used to stop the dye from glowing on one side of the cell, thereby marking the fibers. The laser did not inhibit the normal function of the fibers.

This experiment tests a hypothesis about
a) how chromosomes migrate during cell division
b) how fluorescent dyes work in the cell
c) the effect of lasers on cells
d) the effect of lasers on fluorescent dye
e) why cells divide

A, it proved that the chromatids "eat" the kinetochores as opposed to the centrioles pulling them in.

The "eat" the fibers by breaking down them into smaller molecules as they travel along them.

Laser Removal of Stretch Marks - Is it Safe?

The skin is one of the bases of one's beauty. If there are badges like stretch marks on your skin, you can't help but feel a bit down and unattractive. Psychologically speaking, having these reminders embedded on the skin produce a great effect on one's self-esteem. Don't worry too much because you are not alone in this world who is confronted with the problems on the ugly marks on the skin. This scarring can be oftentimes found on the arms, thighs, legs, stomach, and breasts. They are nonetheless the effect of too much stretching of the skin. But don't fret now. There is a product of modern technology that you can turn to. It is none other than the laser removal of stretch marks.

Experts have discovered that stretch marks come as the result of the interruption in the quality of the dermis which is the inner layer of the skin. When there is not enough elastin and collagen produced underneath the skin, its elasticity and moisture are also affected. Thus, small and indented linear blemishes appear. People who have been through a period of pregnancy, fast weight gain or weight loss, and the growth encountered during puberty can nowadays avail of the laser removal of stretch marks.

Laser Removal of Stretch Marks Elucidated

You may wonder how laser removal technology can actually work on the removal of the scars. Here is the catch. Stretch marks and scars contain the same etiology so therefore the same procedure is done on them. During the procedure, a professional practitioner uses a special kind of laser beam that goes deep through the skin. It then slackens off the collagen fibers which prompt the relaxation of the marks or scars. More so, the laser energy causes some mild tenderness on the dermis structures so the human body is automatically motivated to restructure the said area to produce a new skin. As time goes by, the marks and scars can gradually disappear. A series of laser treatment appointments is sure to give you a positive result.

Every session for the laser removal of stretch marks can take about 30 up to 60 minutes depending on the affected area and their size. The professional practitioner is likely to be the one to suggest to you the number of times that the session needs to be done. It usually depends on the skin color and type as well as the severity of the marks. However, the normal range of treatment sessions occurs for about five up to six times every other month.

The Safety of Laser Removal of Stretch Marks in Question

Many of you may wonder is there is pain felt during the treatment. The pulse of laser can give you a slight feeling of being pinched just like how you will feel when a rubber band is snapped on your skin. But don't worry since the lasers contain a special cooling tool that keeps a tolerable temperature. Therefore, pain is minimized at the most.

The technology used for the laser removal of stretch marks is generally safe. It is often the resort of many people who can no longer contain their worries about these scars and marks. The old and new skin marks are removed since the laser beams are geared towards targeting the mending of the skin's collagen.

With the laser removal of stretch marks, the repair is done both on the inner and outer layers of the skin. When it comes to safety, there is a guarantee. Take note though that it can be really costly.
