Tryptophan and Cortisol Modulate the Kynurenine and Serotonin Transcriptional Pathway in the Kidney of .

Aquaculture fish are kept for long periods in sea cages or tanks. Consequently, accumulated stress causes the fish to present serious problems with critical economic losses. Fish food has been supplemented to reduce this stress, using many components as amino acids such as tryptophan.

Immune Transcriptional Response in Head Kidney Primary Cell Cultures Isolated from the Three Most Important Species in Chilean Salmonids Aquaculture.

Fish cell culture is a common in vitro tool for studies in different fields such as virology, toxicology, pathology and immunology of fish. Fish cell cultures are a promising help to study how to diagnose and control relevant viral and intracellular bacterial infections in aquaculture. They can also be used for developing vaccines and immunostimulants, especially with the ethical demand aiming to reduce and replace the number of fish used in research.

Freshening effect on the osmotic response of the Antarctic spiny plunderfish Harpagifer antarcticus.

Global warming is having a significant impact around the world, modifying environmental conditions in many areas, including in zones that have been thermally stable for thousands of years, such as Antarctica. Stenothermal sedentary intertidal fish species may suffer due to warming, notably if this causes water freshening from increased freshwater inputs. Acute decreases in salinity, from 33 down to 5, were used to assess osmotic responses to environmental salinity fluctuations in Antarctic spiny plunderfish Harpagifer antarcticus, in particular to evaluate if H.

Review of treatment for alopecia totalis and alopecia universalis.

Alopecia areata (AA) is an autoimmune disease directed at the hair follicle. Although usually limited to patchy hair loss over the scalp (focalis), AA can present as total loss of scalp hair (totalis; AT) or as total loss of both scalp and body hair (universalis; AU). Management of AT and AU can be challenging, and although multiple treatment modalities have been explored, no therapy is currently FDA-approved.

Apremilast for the treatment of psoriatic arthritis.

Psoriatic arthritis (PsA) is a chronic inflammatoryarthropathy that affects joints and entheses andis associated with psoriasis (PsO). There are fiveclinical patterns of PsA: symmetrical polyarthritis,distal interphalangeal arthropathy, asymmetricaloligoarthritis, arthritis mutilans, and spondylitis, withor without sacroiliitis. Concerning PsA, the goals oftherapy are to control inflammation, prevent articulardamage, and reduce discomfort in the affected joints.
