Dermis

tanning. There are several ways to tan leather, the more common method is called chrome tanning. Animal skin is made up of three layers: the epidermis, which is the outside layer; the dermis; and the subcutaneous tissue, which is one type of adipose, or fatty, tissue. When making leather, only the strong and flexible dermis, is used. Before beginning the tanning process, the hide is preserved with salt to keep it from rotting. When the hide is ready to begin processing, it is soaked in water…

Q1. Explain segmental trans-splicing (STS) and mention a long gene 8 kb or more, this strategy could be used for. A1. Segmental trans-splicing concept is similar to that of trans-splicing, where exons of two different gene fragments are joined together. However, in STS it can be used to target gene sequences that are too large for a viral vector genetic capacity; for example the von Willbrand factor gene (8.6 kb) or the muscular dystrophy gene (11.0 kb). In STS a 5’exon of the gene is delivered…

one of the pigments responsible for skin color. Langerhan cells- deals with immune response that rise from red bone marrow and migrate to the epidermal cells. Merkel cells- these cells interact with tactile disks to detect the sensation of touch. Dermis- Contains a wide area of dense irregular connective tissue. It has the capability to contract and extend to due its network of collagen and elastic fibers. Microphages, fibroblasts and adipocytes are also present in this tissue. Equipped with…

Mongolian spots (congenital dermal melanocytosis) is an asymptomatic macular, blue-gray rash commonly present at birth or appearing on the sacral region of infants within the first weeks of life. It results from entangled melanocytes in the dermis as they migrate from the neural crest to the epidermis. In most cases, it resolves spontaneously during the first four years of life. Choice "A" is not the best answer. The possibility of child abuse should always be explored when lesions that…

pathological wound healing. It serves as an endothelial cell mitogen, increases vascular hyperpermeability, and promotes deposition of an extravascular fibrin matrix. Multiple studies have indicated that VEGF is expressed at higher levels in the underlying dermis, in epidermal keratinocytes, and in capillary lining cells and fibroblasts of keloids in comparison with normal skin. VEGFs bind to a family of receptor tyrosine kinases (VEGFR-1(FLT1),VEGFR-2( KDR/FLK1),VEGFR-3( FLT 4) . VEGFR-2 is…

Severe acne on the face, chest, and back can cause permanent changes in the skin that we refer to as acne scarring. When pores become clogged with bacteria, oil, and dead skin, it causes inflammation and swelling of the pore. Follicle walls in the skin break because of this swelling. During the repair process, new collagen fibers are formed; however, this process does not return the skin back to its original condition. Once the repair process is complete, it is common to see permanent acne scars…

Pressure ulcers are a serious yet still preventable complication that hospitals are dealing with in all ages, races, and genders. First understanding how a pressure ulcer is formed and what it is. A pressure ulcer is formed when there is rupture in the epithelium
or when there has been significant damage or opening in the protective function of the skin, which could lead to the loss of underlying connective tissue (Catherine Rabess, 2013). A pressure ulcer usually resides around the bony…

The Secret Of Youthful And Radiant Skin YOUR SKIN IS DELICATE There are quite a few factors that may indicate the pace at which the skin decays.There are factors like exposure to direct sun rays and pollution. It could also be your smoking habits or your daily food habits ! The most dominant of these are the genetic or hereditary factors like your skin texture and type. Usually, fair skin turns crinkly more rapidly than wheatish or dark skin as they are shielded by high amounts of lipids and…

First of all, what an amazing read (and movie, of course). I was kind of dreading having to read, what ended up being, 12 pages, but I sure am I glad I did. So much insight, so much juicy information, so much food for thought – my kind of read. Among the many things that I found super interesting and intriguing from the press packet, one of the things that stood out to me the most was how much thought was put into, not only the whole entire film, but every single aspect of it… the meaning of the…

Lidocaine effect. However, epinephrine is contraindicated with single circulation or end such as fingers, toes, ears, and nose. After cleansing the skin with an antiseptic a local anesthetic is applied. The needle is inserted with bleb up under the dermis of the entire wound. Because it is a subcutaneous procedure watch for a flash of blood, and then slowly infiltrate wound as you pull back out with the needle. This is done on each side of the wound. I & D Process:…
