Posted on | by Kelvin

A 30 year old real-estate agent has been feeling generally unwell for the last few days. He has lost his appetite and has not been eating well. He is a smoker, but for the last few days, he hasnt felt like lighting up because of his illness. For the last two days, he has experienced a dull ache on the right side just below his ribs. His eyes looked yellow in the mirror, and his urine has been darker than usual.

After examining, his physician tells him that he has abdominal tenderness, fever (101 oF), and jaundice. His doctor ordered his blood work, and when the results came back, he was told that he had an acute Hepatitis B infection

Fibrocartilage Tissue: Changes Due to Damage and Aging

Posted on | by Kelvin

Pick a type of tissue as the focus of your discussion.For example, connective tissue consists of bone, cartilage, adipose tissue, and others. Pick one of the types of connective tissue rather than the entire group.Try to pick a type unique from your peers.Discuss changes that can occur to this tissue type from damage to the tissue or aging of the tissue. Be specific with the changes that could occur and explain any mechanisms involved with damage or aging of the tissue.Discuss the outcomes of damage or aging of this type of tissue. Does regeneration or repair of this tissue normally occur? Why or Why not? Relate your thought on this to the tissues characteristics.Based on what you know of this tissue type predict if the integrity of the tissue will be maintained after the damage or aging of the tissue? Be specific and explain your position.

Protecting Your Skin: Understanding Sunscreens and Sun-Related Damage

Posted on | by Kelvin

The American Academy of Dermatology (2021) states that skin cancer is the most common cancer in the United States. One in five Americans will develop skin cancer in their lifetime. Protecting our skin from harmful ultraviolet rays is imperative. However, the human body does benefit from a mild to moderate amount of UV radiation.
Initial post: What is the best way to protect your skin from sun-related damage? What are the advantages and disadvantages to sunscreens containing common active ingredients such as oxybenzone, octocrylene, and homosalate? Are there benefits to using mineral sunscreens, such as zinc oxide or titanium dioxide? How effective are natural sunscreens, such as coconut oil or shea butter? If a sunscreen product is not regulated by the FDA, how can you determine if the product’s claims are true?
