â¢ spaces in between cells allow fluid from vessels in the dermis to. nourish the cells (epidermis is avascular!) â¢ Langerhans cells (involved in the immune system) found here. stratum germinativum (basalis) â¢ contains stem cells from which new keratinocytes arise by mitosis. a) these cells are relatively small, cuboidal to low columnar. b) look for mitotic cells with basophilic appearance. â¢ melanocytes are dendritic cells that synthesize melanin.
Fish oil EPA and DHA are both polyunsaturated fatty acids, and each unsaturated bond (double bond) can possibly be oxidized; this would convert the lipid itself into an oxidant capable of producting other oxidants and is a phenomena common to any unsaturated fatty acid including arachidonic acid.
The efficacy level from many of these studies is set between two and three grams (2000-3000mg) per day. Again, remember that we are talking about EPA and DHA, not just fish oil. In fact, the anti-inflammatory reaction of EPA doesnât seem to kick in unless you consume at least 2000mg each day.
