Abstract: The invention relates generally to a composition for rapid and sustained delivery of one or more biologically active agents, and uses thereof, wherein the composition comprises short biocompatible polymer fibres (SPF) having an average length in the range of from about 1 pm to about 3 mm, and an average diameter in the range of from about 15 nm to about 5 ?m, wherein the SPF are loaded with one or more biologically active agents, and wherein, when administered, the composition provides rapid and sustained release of the one or more biologically active agents from the SPF.

Abstract: The invention relates to cDNA libraries obtained from Tammar wallaby (Macropus eugenii) mammary gland tissue at different times (including day 23 pregnancy, day 130 lactation, and day 260 lactation). Lactation-associated polypeptides were identified from these cDNA libraries, and bovine homologues of the wallaby proteins are also disclosed. The proteins have a range of activities including anti-apoptotic activity, pro- or anti-inflammatory activity, cathelicidin anti-microbial activity, induction of trefoil proteins (and protection of epithelial surfaces), increased cell proliferation, and induction of cell differentiation (and loss of pluripotency).
