A recent study conducted by researchers at Tabriz University of Medical Sciences in Iran explored the use of canthaxanthin-loaded seminal exosomes (CAN-loaded EXO) to mitigate the damages caused by sperm cryopreservation. Exosomes were isolated from human seminal fluid and loaded with canthaxanthin using the sonication method. The results showed that the presence of CAN-loaded EXO improved sperm motility, vitality, total antioxidant capacity, and reduced reactive oxygen species levels, lipid peroxidation, sperm DNA fragmentation, and apoptosis. The researchers concluded that exosomes have the potential to serve as a novel drug delivery platform for protecting spermatozoa from cryodamage while enhancing the bioavailability of antioxidants.

A recent study conducted by researchers at the University of Jinan in Guangdong, People's Republic of China, explored the potential of canthaxanthin in mitigating cardiovascular senescence. The study found that canthaxanthin demonstrated the ability to alleviate premature aging in cardiomyocytes in vitro and in an aged mice model. The researchers suggest that canthaxanthin could be used as a biologically active molecule for the treatment of cardiac aging and fibrosis. This research provides valuable insights into the development of strategies to prevent aging-related cardiovascular diseases. [Extracted from the article]

A recent study conducted at Shenzhen University in China explored strategies to improve the production of carotenoids, specifically canthaxanthin and astaxanthin. The researchers focused on increasing the activity of the enzyme beta-carotene ketolase, which is involved in the biosynthesis of canthaxanthin. By employing various strategies such as selecting optimal expression vectors, screening induction temperatures, and adding molecular chaperones, the researchers were able to significantly enhance the soluble expression and activity of beta-carotene ketolase. This study provides a foundation for further research on improving the activity of this enzyme and offers new ideas for increasing carotenoid production. [Extracted from the article]

A recent study conducted by researchers from Fudan University in China explored the potential of canthaxanthin (CX) in treating vascular aging and endothelial cell senescence. The researchers found that CX effectively reduced the expression of senescence-associated molecules and oxidative damage in vascular endothelial cells. Additionally, CX treatment decreased the levels of inflammatory markers. The study suggests that CX has potential application value in addressing vascular aging and endothelial cell senescence.

This article focuses on various issues concerning salon farming in Scotland. When farmed salmon escape into the wild they can spread parasites and disease over a wide area. Because farmed salmon are fed an artificial diet they threaten the sustainability of many species of wild fish too. To counter the spread of such diseases, a farm is authorized to use over 30 different antibiotics, such as oxytetracycline. The farms also discharge contaminated waste directly into the sea. Astaxanthin and canthaxanthin are fed to salmon. Their effect on humans is largely unknown, though canthaxanthin in very high quantities has been shown to damage vision by causing fluid retention in the eye. In the most comprehensive analysis of farmed and wild salmon as of October 2005, it revealed high levels of carcinogenic polychlorinated biphenyls in every sample, however farmed salmon was significantly more polluted than wild salmon.

The article reports that carotenoid supplements are not the only products to have been sold as tanning drugs over the years, but the others either don't work, or worse, present serious health hazards. On the face of it researchers have worthier aims than pandering to people's vanity. Their products could help people with a genuine medical need for the protection afforded by a suntan. The commonest carotenoid, canthaxanthin is banned for sale as a tanning agent in the U.S. because it can cause problems ranging from liver damage to crystals building up in the eye.

Reports on the debate over canthaxanthin, a synthetically produced beta carotene which was given to people who wanted to achieve a tan. Effects on a woman with aplastic anemia; Dr. Richard Stein's investigation of the substance and its physiological effects; Uses of canthaxanthin in the food industry and its strict control by the Food and Drug Administration; Advertisement as a tanning product; Dr. Renata Bluhm's research; Public ignorance of the dangers of these products.

The main purpose of this work was to evaluate the colouring effect of carotenoids present in dry biomass obtained from stressed cells of Chlorella vulgaris. Total carotenoids represented only 0.2% of dry algal biomass and consisted mainly of canthaxanthin, lutein, astaxanthin and their esters. - A rainbow trout feeding trial was conducted in order to investigate the effects of dietary algal incorporation as a pigment source, in comparison to that obtained with synthetic pigments, both astaxanthin and canthaxanthin. - The colour intensities measured in muscle were compared, in each case, with those which constitute the Salmonids Roche Colour Card, and proved similar after both 3 and 6 weeks feeding, with a significant increase detected, but at the end of experiment (9 weeks) the increase was shown only in spectrophotometric (quantitative) results. Chlorella vulgaris biomass, which is storable without any special precautions, thus appears to be a promising source of carotenoids to use in commercial fish finishing diets, quite comparable in efficiency with the existing synthetic pigments. Algal biomass micronization, which was also tried out, was not found to be advantageous for the efficiency of colouring, no evidence having been found of any difference in its absorption and in the distribution of pigment through muscle, even if a 150-g rainbow trout, which has a rather short digestive tract, was used.

The article provides information related to health. A study in the "Canadian Medical Association Journal" shows that 65-year-old or older people at high coronary risk who get pneumococcal vaccine in at least a year earlier were less likely to have a heart attack. Strength training, particularly for quadriceps, reduces pain and improves mobility for people with osteoarthritis of the knee. Tanning pills, which most contain canthaxanthin, has a lot of side effects such as nausea.

The article presents an abstract of the study "Association of carotenoids, tocopherols and vitamin C in plasma with allergic rhinitis and allergic sensitisation in adults," by I. Kompauer and J. Heinrich et al, published in a 2006 issue of "Public Health Nutrition."
