Carotenogênese em células de Haematococcus pluvialis induzidas pelos estresses luminoso e nutricional

The objective of this work was to evaluate the responses of Haematococcus pluvialis cells to the carotenogenesis induction process, under light and nutrition stress. Cells were acclimated during 15 days in WC medium, with aeration with synthetic, filtered atmospheric air and flow rate of 100 mL min-1, light intensity of 50 µmol photons m-2 s-1, photoperiod of 12 hours, and temperature of 23ºC. The following two treatments were compared: cultivation under the described conditions, but with increase of light intensity up to 350 µmol photons m-2 s-1 ; and cultivation under the same conditions as the previous treatment, but with aeration containing 4% CO2. The treatments were done in triplicate, during ten days. With the addition of CO2 and the increment in lighting, an increase was observed in the carotenoids/chlorophyll ratio and cell biomass. Cells stopped dividing on the second day of stress, when nitrate became limiting, and significantly increased their biovolume. The excretion of organic carbon and the concentration of astaxanthin increase in response to the addition of CO2. Stress by light intensity combined with CO2 addition optimizes carotenogenesis in H. pluvialis and increases astaxanthin production.

Uso de células-tronco para o tratamento de tendinite em eqüinos

Brazil has the fourth largest horse herd in the world, this is due the recognition and appreciation that the different equestrian games are having within the country. Injuries of the tendon, especially in the digital flexor tendon, are the main cause of athletic life reduction among horses. The treatment of tendinitis in horses seeks full recovery of the damage tissue reestablishing the function previously lost, however conventional treatments have proven to be ineffective when considered the quality of the scar tissue and the rate of recurrence. Due to this, the use of adult stem cells to the treatment of musculoskeletal injuries of horses has been studied for some time. This method of treatment consists of aspiration of bone marrow or removal of subcutaneous fat tissue and implantation of these cells in the injured tissue. After obtaining the bone marrow the implantation can be performed with total bone marrow, with the mononuclear fraction of MSC or with cells cultured in vitro. From the fat tissue is used the stromal vascular fraction obtained by collagenase digestion, followed or not by cell culture. According to some studies, cell therapy with material obtained from bone marrow or adipose tissue has shown to be viable, given that these materials are abundant in repair components such as mesenchymal stem cells (MSC), growth factors and other components of the collagen matrix. Several studies using both types of cells have shown great potential and promising clinical results. However, knowledge of the biology and characterization of these cells remain largely unknown, and therefore is needed great care and caution when using stem cells for the treatment of musculoskeletal disorders in horses

Atividade espontânea e estimulação do inseto (T. molitor)

The heart of the insect is essentially myogenic, in others words, electrical activity and spontaneous contractions are generated by their muscle cells. However, the nature of pacemaker activity is not yet fully elucidated. One aspect that deserves attention, beyond the pacemaker activity, is the amplitude of heart contractions of the insect. For this, it is necessary that the heart to be stimulated electrically to the frequency to be controlled. In the present work, it was developed a method of stimulation (preparation and instrumentation). The contractile activity of the heart of the insect remained regular when stimulated at frequencies lightly above the spontaneous frequency. To characterize excitability of the preparation the intensity-duration curve was determined
