Research Summary: Humans are exposed to various external environmental factors, with food intake being one of the most influential factors impacting daily lifestyle. Among the nutrients obtained from foods, omega-3 polyunsaturated fatty acids (PUFAs) have been shown to have various beneficial effects on inflammatory diseases. Furthermore, omega-3 PUFA metabolites, including resolvins, are known to exhibit strong anti-inflammatory effects during allergic and inflammatory diseases. However, little is known about the actual impact of these metabolites on skin diseases.In this review, we focused on metabolites that have strong anti-inflammatory actions in various inflammatory diseases, as well as those that present antitumor actions...

Research Summary: Various kinds of soils can be formed from volcanic ash, depending on the specific set of soil-forming factors at different sites. Among these soils, Andisols or Andosols exhibit unique properties, largely due to the abundance of noncrystalline materials such as allophane, imogolite, Al-humus complexes, and ferrihydrite. These materials create highly porous structures in Andisols, resulting in a light and fluffy nature that can accommodate large amounts of both plant-available and hygroscopic water. These soils also possess many other physical properties that differ from those of other soils.In addition to their physical characteristics, Andisols have unique chemical properties. These...

Research Summary: The skin is constantly exposed to various environmental stresses, particularly the damage caused by pollution and ultraviolet (UV) radiation. As a consequence, the outer layer of the skin can be negatively impacted by the harmful influence of some of its surface components. The mechanisms involved in the degradation processes promoted by UV radiation are driven by the direct absorption of radiation via cellular chromophores, the formation of excited states, and the consequent chemical reactions. In addition, photosensitization mechanisms occur, in which UV light is absorbed by sensitizers that become excited, leading to the formation of reactive oxygen species...

Research Summary: The aging population and a desire to maintain a youthful appearance have propelled the recent surge in the U.S. cosmeceuticals market. The rapidly growing number of products claiming to diminish fine lines and wrinkles, decrease redness, smooth texture, and fade discoloration has led to much confusion and misinformation among dermatologists and consumers alike.Cosmeceuticals can be a useful adjunct to prescription medications and office procedures. Therefore, it is important for dermatologists to understand the science behind these products to better educate themselves and their patients.We present an update on the following categories of cosmeceuticals: antioxidants, growth factors, peptides, anti-inflammatories/botanicals,...
