Skin Cancer01:30

Skin Cancer

5.9K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

DNA Damage Can Stall the Cell Cycle02:36

DNA Damage Can Stall the Cell Cycle

3.1K
In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...

Sensory Functions of the Skin01:16

Sensory Functions of the Skin

8.1K
The skin is the largest organ of the human body and plays a crucial role in our sensory perception. It contains a vast network of sensory receptors that contribute to the skin's protective function by perceiving physical, biological, and environmental cues and generating relevant responses.
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...

Skin Diseases and Disorders01:23

Skin Diseases and Disorders

5.4K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

7.8K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

Area of Science:

  • Environmental Science
  • Dermatology
  • Public Health

Background:

  • Tropospheric ozone (O3) is a secondary pollutant formed in sunlight.
  • O3 exposure is linked to pulmonary, cardiovascular, reproductive, and nervous system issues.
  • The skin's role as a target organ for O3 is under-explored.

Purpose of the Study:

  • To investigate the impact of ambient ozone exposure on skin health.
  • To review evidence linking O3 to cutaneous oxidative damage and inflammation.
  • To assess epidemiological data on O3 and skin aging.

Main Methods:

  • Review of experimental studies on O3 effects on skin.
  • Analysis of time series data correlating O3 levels with dermatological consultations.
  • Examination of epidemiological studies on long-term O3 exposure and skin aging.

Main Results:

  • Experimental data indicate O3 exposure causes skin oxidative damage, reduced antioxidant defense, and inflammation.
  • Acute increases in O3 levels correlate with increased medical visits for skin conditions.
  • Preliminary evidence suggests long-term O3 exposure is associated with premature skin aging, independent of other pollutants.

Conclusions:

  • The skin is a potential target organ for ambient ozone.
  • Adverse cutaneous effects of ozone exposure are a growing public health concern.
  • Further research is needed to confirm O3 specificity and mechanisms for skin aging.
