million new cases estimated in the U.S. each year. Not only is it the most common skin cancer, but it is the most common of all types of cancer. One in four Americans are likely to develop a basal cell carcinoma. Basal cells line the deepest layer of epidermis. The growths are malignant tumors that arise in this layer of skin. BCCs occur most frequently on sun-exposed regions of the body. Although this skin cancer rarely spreads to other organs of the body (i.e., metastasizes), it can cause…

The Animal Book Chapter 1: Animal characteristics Chapter 2: Body Parts Body plans refer to similarities in development, structure, and function among members of a particular group (phylum). At some point, members of that group share the same body plan during their development process. Which could be a possible explanation for shared structural plans that have been observed in the anatomy and embryology. Timing, pattern, and scale of development determine the organism's shape, and closely…

type of radiation, but does not penetrate the earth’s ozone layer unlike ultraviolet A and B (Medicinenet, 2013). Ultraviolet A stimulates melanin pigmentation, as it is able to reach deep into the dermis. Ultraviolet B is mainly absorbed by the epidermis and upper dermis, and is also responsible for pre-vitamin D3 production in the skin as well as stimulating the production of melanin like ultraviolet A. With continuous exposure to ultraviolet radiation, there is a higher chance of DNA damage…

Pressure Ulcers Pressure ulcers are a chronic wound that attacks the skin. Pressure ulcers also known as bedsores. Risk facts The most common risk factor of pressure ulcers is immobility: Improper nutrition is also a risk factor of pressure ulcers. Alzheimer’s disease considered a risk factor because of impairment of mental status (Berman&Slon, 2012). Because of their mental status, patients are unaware of the prevention of pressure ulcers, which makes them more vulnerable to pressure ulcers.…

function. Everything from the outer layer of the skin to the core of the bone is necessary for the joint to articulate properly. The most superficial layer of the knee is the skin, which is the largest organ of the human body and is made up of the epidermis and dermis, which in turn are made up of keratinized stratified squamous epithelium as well as dense, irregular collagenous connective tissue and glands, respectively (4). The most important function of the skin at the knee joint is to…

cancer gene 163 sporadic BCC’s were analyzed as well as 4 Gorlin syndrome BCC’s. These BCC’s were analyzed against 387 known cancer-related genes. The last method was RNA sequencing of 61 BCC’s and 25 single matched samples of normal epidermis. The normal epidermis samples were compared to the 61 BCC’s to analyze what genes were expressed and not expressed creating an expression profile (Ximena 399. Results Mutational signatures of BCC include a profile of BCC that was predictable due to the…

Periodontics is a large specialized field within the practice of dentistry. Periodontists focus on prevention, diagnosis and treatment of oral disease. Periodontists use a wide range of procedures from tooth scaling, root planing and, in more severe cases, tissue or bone grafts. The periodontium is the supporting structure to the tooth and consists of the gingiva, cementum, alveolar bone and periodontal ligaments. Gingiva, also known as gum tissue, surrounds the tooth and acts as a barrier to…

action Skin is a multilayered organ with the ability to protect the organ¬ism against external aggressions. The skin consists of three main layers including epidermis, dermis and subcutis that are responsible for its high turnover capacity in repairing different injuries. Similar to other tissues, the stem cells existed in skin tissue play an important role in regulating the balance between cell loss and cell division [22, 23]. siRNA therapeutics are potent alternative for skin regeneration due…

be blamed on the genes. Though the sun’s anger manifest on our skin in the long run, we are still in full control in order that it cannot cause havoc in the epidermis. Tip No.3: You Have An Obsession With Sugar Sugar not only destroys your teeth and your body, it damages your skin through a process called glycation. Sugar invades your epidermis causing disturbance in your skin’s pH balance. Your skin becomes a haven of bacteria that cause redness and acne to your skin. The collagen and elastin…

system to the immune system. There are three main types of skin cancer that is caused by the abnormal growth of cells within the skin. There is the basal cell carcinoma that starts off in the basal cells, squamous cell carcinoma that forms in the epidermis, and the malignant melanoma which happens when the melanin has become cancerous. Many people around the world have been diagnosed with one of these cancers and has suffered from how it has caused their bodies to change drastically. The basal…
