Green composites combine the property of individual constituents, that is, fibre and polymer. Their properties vary with plant source, species and geographical conditions. In this study, there is an assessment of the properties of grewia optiva, Himalayan nettle and silk, reinforced in poly lactic acid. Natural fibres are lightweight. These are having important characteristics to replace the steel and wood, challenging non- biodegradable composites. Results show that silk fibre is having better properties than rest of the two. Spider silk is having five times more tensile strength than that steel. Reinforcement of short fibre will increase the ductility of composite. [ABSTRACT FROM AUTHOR]

Somatostatin (SST), a growth hormone inhibitory peptide, is expressed in endocrine and non-endocrine tissues, immune cells and the central nervous system (CNS). Post-release from secretory or immune cells, the first most appreciated role that SST exhibits is the antiproliferative effect in target tissue that served as a potential therapeutic intervention in various tumours of different origins. The SST-mediated in vivo and/or in vitro antiproliferative effect in the tumour is considered direct via activation of five different somatostatin receptor subtypes (SSTR1-5), which are well expressed in most tumours and often more than one receptor in a single cell. Second, the indirect effect is associated with the regulation of growth factors. SSTR subtypes are crucial in tumour diagnosis and prognosis. In this review, with the recent development of new SST analogues and receptor-specific agonists with emerging functional consequences of signaling pathways are promising therapeutic avenues in tumours of different origins that are discussed.
