Brazilian Archives of Biology and Technology , 2005, DOI: 10.1590/S1516-89132005000300010
Abstract: the effect of feeding methods on the production of astaxanthin by the yeast phaffia rhodozyma atcc 24202 was studied, using continuous and pulsed fed-batch processes and low cost materials as substrates (sugar cane juice and urea). in continuous fed-batch processes, a cellular astaxanthin concentration of 383.73 μg/g biomass was obtained. but in pulsed fed-batch processes a reduction in the cellular astaxanthin concentration (303.34 μg/g biomass) was observed. thus the continuous fed-batch processes could be an alternative to industrial production of astaxanthin, allowing an increase in the biomass productivity without losses on astaxanthin production by the yeast.

Abstract: the yeast phaffia rhodozyma produces astaxanthin, a carotenoid pigment widely applied in fish and crustaceous cultivation. this yeast can be efficiently cultured in a low cost medium, sugar cane broth diluted 1:10 and supplemented with 1 g/l urea. however, the biomass and astaxanthin production undergo inhibition by the substrate (crabtree effect), limiting the utilization of sugar cane broth up to 20 g/l total sugar concentration. therefore, this effect must be considered during the industrial production of astaxanthin. in the present work, using fed batch system to cultivate p. rhodozyma we were able to obtain 0.024 mg astaxanthin/l.h compared to 0.013 mg astaxanthin/l.h obtained by the discontinuous cultivation system.
Photochemical and photobiological properties of furocoumarins and homologues drugs
F. Bordin
International Journal of Photoenergy , 1999, DOI: 10.1155/s1110662x9900001x
Abstract: Furocoumarins are natural photosensitizing drugs used in PUVA photochemotherapy and in photopheresis. Their therapeutic effectiveness is connected to the lesions they induce to various cell components, membranes, ribosomes, mitochondria, and in particular to DNA, damaged by formation of monofunctional adducts and of inter-strand cross-links (ISC). ISC represent a severe damage, mainly correlated to the main side effects observed in photochemotherapy, skin phototoxicity and genotoxicity. Searching for new monofunctional derivatives, two tetramethylfuroquinolinones, 1,4,6,8-tetramethyl-2H-furo[2,3-h]quinolin-2- one (FQ) and 4,6,8,9-tetramethyl-2H-furo[2,3-h]-quinolin-2-one (HFQ) were studied. Both compounds are very active; however while FQ produced many chromosomal aberrations and strong skin erythemas, HFQ practically did not induce such side effects. FQ and HFQ formed high levels of monoadducts but no ISC in DNA, but both provoked many DNA-protein cross-links (DPC). FQ induced these lesions by a biphotonic reaction: at first a furan-side monoadduct is formed, which is then converted into a DPC; thus the FQ molecule seemed to form the bridge between DNA and proteins. HFQ formed DPC by a single step (DPC at zero length, like UVC). For these features, HFQ appears to be the first molecule belonging to a new class of active but not phototoxic drugs for photomedicine.

Abstract: “Utopia,” from the combination of the Greek diminutive plural of topos, that is “place,” and the pun between the two prefixes ou, “non-,” and eu, “good,” is a term that is not-so-often used in the twenty-first century. It rather reminds us of bygone centuries, when scientists, philosophers, publishers or writers had time to dream and discuss of possible societies, and were not forced to face the disillusionments of a post-modern and a post-industrial society in which scholars are more and mo...
Anemia hemolítica auto-imune e outras manifesta??es imunes da leucemia linfocítica cr?nica
Bordin, José O.;
Revista Brasileira de Hematologia e Hemoterapia , 2005, DOI: 10.1590/S1516-84842005000400008
Abstract: chronic lymphocytic leukemia (cll) is frequently associated with autoimmune diseases directed against hematopoietic cells, including autoimmune hemolytic anemia (aiha), immune thrombocytopenic purpura (itp), pure red cell aplasia (prca), and immune neutropenia. cll represents the diagnosis in up to 15% of the patients with aiha, and in 50% of the patients with aiha secondary to malignancy. itp occurs in 2% and prca in about 1% of all cll patients. prednisone is the first-line treatment for immune cytopenia related to cll. about 60% of patients relapse when treatment is stopped therefore splenectomy, intravenous immunoglobulin, or cyclosporine are reasonable second-line treatments. although the data on pathophysiology are very limited, it appears that the autoimmune mechanisms are related to the activity of the leukemic b lymphocytes that act as aberrant antigen-presenting cells, and are effective in processing and presenting proteins derived from red cells or platelets to auto-reactive th cells. th cells specific for certain auto-antigens escape from control mechanisms and when activated may initiate auto-immune disease. patients with aiha secondary to cll should not receive fludarabine because there is an increased frequency of severe and fatal aiha in patients treated with purine nucleoside analogues. patients who are more immunosuppressed due to several previous treatments are at higher risk for developing this auto-immune complication.
