    摘要： Compositions and methods are provided for the nucleic acid mimic determination of nucleic acids. The compositions and methods may be used in the diagnosis and treatment of diseases amenable through modulation of nucleic acids which encode proteins that are implicated in disease states. In accordance with preferred embodiments, mimics are comprised of non-naturally occurring backbones to which are appended modified heterocyclic bases. Such bases preferably have sterically bulky substituents 1, 2, or 3 atoms removed from the sites of attachment to the backbone.

    摘要： A method and apparatus for sequentially degrading at least a portion of a polymer of backbone repeating units, the polymer having a terminal repeating unit comprised of a nucleophile and a backbone carbonyl carbon distant from the nucleophile, comprising the steps of first initiating attack of said nucleophile upon said backbone carbonyl carbon by raising the energy level to activate said nucleophile for said attack. Secondly, forming a ring comprising the terminal repeating unit, thereby simultaneously releasing the ring and generating a shortened polymer having a terminal repeating unit capable of nucleophile attack upon the backbone carbonyl carbon and, lastly, maintaining the reaction conditions necessary for repeating steps a and b until the portion of the polymer desired is degraded. In a related embodiment, polyamide nucleic acid (PNA) sequences can be determined by generating a nested set of polymer fragments, each fragment having N-x repeating units where N is the total number of repeating units in the parent polymer and x is the number of degradation cycles the fragment has been subjected to, and then analyzing the nested set of polymer fragments to determine polymer sequence. An apparatus embodying the method of sequential degradation is also described. Analysis may be by MALD-TOF.

    摘要： Animals such as pigs which are to be slaughtered at slaughterhouses are unloaded from the transport truck and driven into pens and stalled in these for some time, until they are driven out of the pens and over to a stunning apparatus. The pigs of a supplied lot to the slaughterhouse, or part of the supplied lot, are treated as a separate unit during one or more of the above-mentioned stages of treatment, which means that pigs of a unit are to be constantly kept separated from pigs belonging to other units. Each unit may comprise e.g. 15 pigs. The treatment of the animals in units reduces their aggressions, and their well-being is increased, which will result in a lower incidence of rind damages, blood splashings and deviant meat quality of the carcasses. A system for stalling of the pigs includes a number of oblong pens (1), which are placed next to each other. Each of the pens has an entrance gate (6), an exit gate (8) and a driving gate (10) which is movable in the longitudinal direction of the pen. Each pen is equipped with one or more stationary intermediate gates (4), which are placed at such a distance from each other, the entrance gate (6) and the exit gate (8), that the pen is divided into several rooms (3a, 3b, 3c). The size of each room corresponds preferably to the size of the unit of pigs which is to be treated.
