Mammals are brought to a specific state of immunization by administering an amount of an antigenic substance sufficient to elicit an immunization response to said mammal, said antigenic substance being incorporated within a shaped structure of a biocompatible matrix material.

A method for chemical modification of mammal urine and mammal blood is disclosed.

4-Amino-6-arylpyrimidines and salts thereof, a novel class of inhibitors of platelet aggregation and broncho-dilators in mammals, and 4-hydroxy-6-arylpyrimidines as useful intermediates.

A gate is provided in a seine fishing net to allow sea mammals entrapped with fist in the net to escape. The gate is selectively inflated or deflated so that it may be raised to the surface or lowered, and is disposed in position in place of floatation devices at the upper extremity of a section of the net. A ribbon net is connected to one side of the gate and is drawn between schools of sea mammals and entrapped fish to allow the sea mammals to escape through the gate while discouraging the fis...

An acquatic retrieval apparatus is provided which includes a flotation bag, gas pressure bottle which is associated with the flotation bag for inflating the bag, a puncturing device connected to the pressure bottle for puncturing the bottle to let the pressurized gas into the bag, a timer connected to the puncturing device for activating the puncturing device so as to puncture the bottle after a predetermined time, and an on-off switch adapted to be connected to a power source for applying power...

An innovative communication device and learning tool that enables marine mammals, such as dolphins, to communicate with humans and with each other. The communication device includes a keyboard having a plurality of hollow keys. Each key includes a switch which can be activated by the dolphin, and a two- or three-dimensional object which can be distinguished by dolphins from other objects in other keys both visually and through echolocation. A microprocessor based controller can be used to associ...

A method for chemical modification of mammal urine and mammal blood is disclosed.

A mammal milking device includes a milk collection container, a vacuum generating device, and a teat attachment member. The teat attachment member is formed such that it forms an angle of between about 45 and 135 degrees between the teat attachment end and the vacuum attachment end. The vacuum generating device operates to pass milk from a mammal's teat, through the teat attachment member, and into the milk collection container. The teat attachment end is configured with a predetermined size for...

Human basement membrane matrix is provided, produced by a novel tumorigenic cell line, where the basement membrane can be used for the growth of a variety of cells, in culture and in vivo. Other cell lines are provided, which may serve to evaluate in vivo the response of tumorigenic cells to various agents, including basement membrane. The basement membrane finds use in allowing the growth of cells in culture and in vivo, particularly cells which are otherwise refractory to xenografting.

Provided are mammalian secreted and non-secreted diabetes mediating proteins, including protective and deleterious diabetes-mediating proteins, as well as polynucleotides encoding same, drug screening methods for identifying a test compound capable of altering the expression of a diabetes-mediating protein, and methods of preventing or ameliorating diabetes by administering a compound capable of the expression of a diabetes-mediating protein.
