Abstract: A perforating gun, system and method is provided. The perforating gun includes a body, a plurality of shaped charges, at least one initial propellant and may include an actuating mechanism. The plurality of shaped charges are mounted within the body, and each shaped charge has an amount of an explosive material. The actuating mechanism is in communication with each shaped charge and the at least one initial propellant. The actuating mechanism is configured to fire the at least one initial propellant before firing any of the plurality of shaped charges.

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).
