Sahurda – ‘Music of the World’ Album
A set of world class professional musicians from the United States of America are giving life to the work of a Sri Lankan composer in this compact disk, possibly for the first time in the history of Sri Lankan music. Pradeep Ratnayake collaborated with these musicians and Professors of music during his time as a Fulbright scholar at the Columbia University, New York, which he attended on United States-Sri Lanka Fulbright scholarship from 2008 to 2010. The brotherhood he found among the musicians and teachers in New York, and among the Sri Lankans in New Jersey who helped him record this music, inspired the name of this CD.
Wine from Wild Grape Berries
Ampelocissus indica (L.) planch is a wild grape, native to Asia that has not yet been adequately recognized by researchers. This species is abundant in the Southern Province of Sri Lanka. As a value added product, wine samples were prepared using fruit of wild grapes and a few wine quality parameters were analyzed proposed by Jean L. Jacobson. Acid level/ titrable acidity, pH level, Specific gravity and Alcohol content (v/v) of wine samples prepared from wild grape berries were 0.72 g L -1 , 3.12, 0.9823 and 13.85 % respectively. It shows that the qualities of wine samples prepared from wild grapes are comparable within the standard quality parameter limits as well as with the normal European grape wine sample qualities.
Sandeshawali Kawinaluwa (සන්දෙශාවලි කවිනළුව)
Sandeshavali Kavi Naluva is founded on Sandesha Kavya, namely; Paravi Sandeshaya, Kokila Sandeshaya, Selalihini Sandeshaya, Gira Sandeshaya and Hansa Sandeshaya written during the Kotte period of the Sri Lankan history. The performance, specifically set against the backdrop of the reign of the king Parakramabahu VI of the kingdom of Kotte during 1412-1467, draws on the traditions of Musical Theatre and Poetic Drama. It enacts the core of the Sandesha Kavya, and portrays on-stage a significant facet of the Sri Lankan literary history to the 21st century audience.

They are good source of minerals, vitamins and phytonutrients.The porridge made of green leaves consumed as breakfast as a practised by most Sri Lankans since ancient times. By preparing rice based porridges and using the knowledge of indigenous medicine health benefits of these porridges can be studied.
A novel tridentate ligand and its fac-Re(CO) 3 L complex as potential imaging and therapeutic agents for lung cancer
A novel napthlane-derivatized ligand and its rhenium tricarbonyl complex have
been synthesized and characterized. Biological studies have shown promising
results where NCI-H292 cells treated with the metal complex indicated apparent
morphological changes, such as cell shrinkage, reduction in cell volume and
irregular cell shapes, which are indicative of apoptoic cell death. Thus, these
compounds could be further investigated as therapeutic agents for lung cancer.
We have been able to formulate a novel potent therapeutic agent for breast cancer through targeting sigma receptors which are over expressed in breast cancer cells. We have also explored the ability of these metal complexes to serve as biological imaging agents. Currently we have some exciting work lined up to explore the use of metal complexes in tracking the various stages of cell apoptosis.
