An examination of the carotene fractions extracted from Euglena gracilis Z and pressure-bleached Euglena mutants PR-1, PR-2, PR-3, and PR-4 revealed phytoene in mutants PR-1, PR-2, and PR-3. Photosynthetic E. gracilis Z cultured at different light intensities showed no detectable phytoene, nor was phytoene found in mutant PR-4. However, dark-cultured E. gracilis Z yielded readily assayable amou...

BACKGROUND Semitendinosus and gracilis muscles whose tendons are used in surgical reconstruction of the anterior cruciate ligament maintain their contractile ability, and a limited decrease of hamstring muscles force is observed postoperatively despite important changes. The goal was to quantify the influence of the myofascial structures on excursions and moment arms of knee muscles to attempt ...

Branchioblastoma in Sardinella longiceps is described in present study. Large tumour masses were found under the operculum. Tumour is characterized by the multilobed and pale to red in color and located in the brachial chamber of the fish. It varied in consistency from very soft and triable to hard and also vary in size from 17 mm to 33 mm in diameter and 18 to 44 mm in length. Prevalence study...

Euglena gracilis was found to contain a peroxidase that specifically requires L-ascorbic acid as the natural electron donor in the cytosol. The presence of an oxidation-reduction system metabolizing L-ascorbic acid was demonstrated in Euglena cells. Oxidation of L-ascorbic acid by the peroxidase, and the absence of ascorbic acid oxidase activity, suggests that the system functions to remove H20...

BACKGROUND Microalgae have recently been attracting attention as a potential platform for the production of biofuels. Euglena gracilis, a unicellular phytoflagellate, has been proposed as an attractive feedstock to produce biodiesel because it can produce large amounts of wax esters, consisting of medium-chain fatty acids and alcohols with 14:0 carbon chains. E. gracilis cells highly accumulate...

The development of reliable, sustainable, and economical sources of alternative fuels is an important, but challenging goal for the world. As an alternative to liquid fossil fuels, algal biofuel is expected to play a key role in alleviating global warming since algae absorb atmospheric CO2 via photosynthesis. Among various algae for fuel production, Euglena gracilis is an attractive microalgal ...

Intractable rectovaginal fistula (RVF) is a troublesome complication after treatment of perineal cancers or infection. Complex fistulas which are larger than 2.5 cm in diameter or the recurrent cases may be repaired with abdominal procedure or tissue transposition. Gracilis muscle flap is widely used in various reconstruction in regarding to the donor site deformity and bacterial resistance. En...

The chloroplasts of Euglena gracilis bounded by three membranes arose via secondary endosymbiosis of a green alga in a heterotrophic euglenozoan host. Many genes were transferred from symbiont to the host nucleus. A subset of Euglena nuclear genes of predominately symbiont, but also host, or other origin have obtained complex presequences required for chloroplast targeting. This study has revea...
