Abstract: The present invention relates to compositions comprising at least one nucleic acid and one lipopolyamine, and their utilisation in gene therapy, particularly for the transfert in vivo of nucleic acids.

Abstract: New lipopolyamines of general formula (I), their salts, their preparation and their use. ##STR1## n=1 to 5 and m=2 to 6 R represents a radical ##STR2## (R.sub.1 and R.sub.2 : aliphatic radical containing 12 to 22 carbon atoms; R: hydrogen atom or alkyl radical optionally substituted with phenyl), or a radical ##STR3## (X=CH.sub.2, CO; R.sub.3 and R.sub.4 aliphatic radical containing 11 to 21 carbon atoms), their preparation and their use.The lipopolyamines of general formula (I) are especially useful as vectors for the transfection of eukaryotic cells.

Abstract: Intermediate compounds useful for producing transfecting lipopolyamines, comprising: ##STR1## wherein m is an integer between 2 and 6 inclusive, wherein n is an integer between 2 and 5 inclusive, wherein R.sub.5 represents a hydrogen atom or a carboxyl radical but no more than one R.sub.5 represents a carboxyl, the values of m in the different fragments (CH).sub.m may be identical or different, and wherein the symbol Z R.sub.5 represent a group protecting the amine function.

Abstract: A portable fish holder for convenient, safe cleaning and filleting of a fish. The invention is comprised of one rectangular base panel, two panel support walls, one affixed transversely at each end of the base, and two positionable rectangular fish support panels. Both fish support panels have outwardly extending hinge pins at each end which are movably held in specifically structured grooves in the inward facing surface of each of the panel support walls. The shape of the grooves allows variable positioning of both fish support panels. A locked V-shape arrangement of both fish support panels is useful for holding a fish in a supine position for cleaning. Both fish support panels are also positionable parallel to the surface of the base. A tail securing clamp is provided on the backside of one support panel for use in securing the fish while scaling and filleting. A knife holder is also provided on the side of one fish support panel.

Abstract: A lightweight plastic or metal lockable water ski rack is provided for use in pairs designed to be either removably or permanently attached to a boat. The water ski rack is a two-piece flattened substantially rectangular structure with slots for two water skis and a tow rope. A lower framed panel as a supporting base of each rack is bracketed to the ski boat and a hinged upper framed panel locks down and retains the skis. Ski slots in the lower framed panel are lined with a protective material and slots in the upper panel are fronted with an elastic retainer band. When the upper framed panel is closed down on the lower framed panel with skis in the slots, the elastic retainer band expands into the upper slots and retains the skis in a manner to prevent rattling. Provisions are included for the two closed panels to be locked together by a padlock.
