We report a 50-year-old female with high grade round cell liposarcoma of the left knee with metastases to the right heart chambers. The tumor was located in the right atrium with extension to right ventricle. The Patient underwent radiotherapy after surgical resection and 12-month follow-up revealed no recurrent cardiac disease.

A better alternative is the bioethanol production by the fermentation of sugars from the waste of agricultural, forestry or industrial processes. Sniace is a chemical industry which main business is the production of cellulose and viscose. A spent liquor containing a high concentration of sugars is obtained in the pulp production process. The sugars of this residue, mainly pentoses, could be used as fermentation substrate for the production of bioethanol by Pichia stipitis. During the pre-treatment stage, the production of compounds, other than sugars, can occur. These compounds may inhibit the fermentation stage, and their influence must be taken into account. Furfural is one of this compound. In this work we have studied the effect of increasing concentrations of furfural in the spent cooking liquor to be used as a substrate for fermentation by P. stipitis. Our results showed that furfural concentrations above 1 g/L inhibit the growth of the strains.

Study Design: Optimization of different physiological and nutritional parameters for amylase production and kinetic studies of amylase. Place and Duration of Study: Soil Samples: Herbal garden of Amity University Haryana, Gurgaon (Manesar), India, between April 2012 and September 2012. Methodology: Amylolytic isolates were selected by flooding the nutrient agar plates containing 2% starch with Lugol solution. Isolates were selected on the basis of higher ratio of clear zone to colony size and grown in nutrient broth containing 2% starch. The level of amylase was detected in the culture filtrate. The selected isolate showing maximum amylase production was identified on the basis of 16S rDNA amplification. Results: An Alkalo-thermostable amylase producing bacterial isolate from soil was identified as Bacillus sp. strain PM1 on the basis of 16S rRNA. It yielded 3.5 U/ml of amylase in medium containing (%) starch 2.0, beef extract 0.5, NaCl 0.5 at 50ºC, pH 7.0 at 180 rpm after 72 h. The optimum pH and temperature for amylase activity was 8.0 and 50°C, respectively. The enzyme exhibited 67% activity after 60 minute incubation at 50ºC.

For chemical compositions, all specimens were imaged and analyzed by scanning electron microscopy and electron probe microanalysis (EPMA). The physical properties were performed according to ISO 6876:2001. Working time, pH, and dimensional changes of NEC and MTA showed similar results. Shorter setting time was obtained with the NEC compared with MTA (p Ͻ 0.05). The NEC showed more flow than MTA. In addition, the film thickness of the NEC was considerably less than the MTA (p Ͻ 0.01 and p Ͻ 0.001, respectively). EPMA investigations indicated that lime (CaO) was the dominant compound in NEC and MTA; however, other compounds were significantly different. It was concluded that the chemical composition of NEC is different compare with MTA; it can be concluded that the NEC exhibits acceptable physical properties. (J Endod 2008;34:990 -993)
