  • Patent number: 7188839
    Abstract: A method of playing an entertainment game includes selecting a lead participant who is required to perform at least one qualifying action in a first level of play. The lead participant is rewarded preferably by a monetary reward upon completion of the requisite number of qualifying actions in the level of play. The lead participant may select an ally from a resource pool to assist in performing the qualifying action. The ally shares with the lead participant in the reward. Preferably there are multiple levels of play with higher degrees of difficulty and with greater rewards.

  • Patent number: 7071293
    Abstract: The present invention relates to the use of antimicrobial peptides in the inhibition of microbial growth and proliferation. Novel antimicrobial truncated peptides are disclosed which are based upon SMAP 29 and RCAP 18, but which contain a lesser number of amino acid residues yet still retain bactericidal activity. In addition, synthetic peptides based upon the SMAP 29 protein are disclosed which have fewer amino acid residues and include substitutions yet retain substantial activity. The invention also relates to a method of inhibiting microbial growth by administering an effective amount of a peptide in accordance with the invention, or by combining the peptides with other antimicrobial agents or antibiotics.

  • Publication number: 20050272645
    Abstract: Retrocyclin peptides are small antimicrobial agents with potent activity against bacteria and viruses. The peptides are nonhemolytic, and exhibit minimal in vitro cytotoxicity. A pharmaceutical composition comprising retrocyclin as an active agent is administered therapeutically to a patient suffering from a bacterial and/or viral infection, or to an individual facing exposure to a bacterial and/or viral infection, especially one caused by the HIV-1 retrovirus or other sexually-transmitted pathogens.

  • Patent number: 6165519
    Abstract: A filter for the adsorption of ingredients from and/or the dispersion of ingredients into a fluid includes a matrix which has a plurality of particles having an inherently active surface or an active surface made of a fluid treating material. The particles are held in place by a moderately viscous binder which is impervious to the flow of the fluid. The particles, however, are made of a fluid pervious material. An insufficient amount of binder is incorporated in the matrix to otherwise completely cover the particles. Thus portions of the active surface of the particles remains exposed to the flow of fluid thereby resulting in tortuous paths of flow through the matrix, thereby assuring contact with the treating particles.

  • Patent number: 5958478
    Abstract: A filtration device for the preparation of foods from food concentrates and liquids includes a composite formed from a plurality of layers having a food preparation applicator secured to the composite at the fluid contact region of the composite. The food preparation applicator includes food concentrate so as to result in a dispensing structure having the food concentrate therein which applies the food concentrate to liquid flowing through the applicator so as to mix the food concentrate with the liquid in the food preparation. The device may also include pockets containing treating material for removing contaminants.

  • Patent number: 5567461
    Abstract: A filter for fluids includes a pair of layers or multiple layers or pairs of material joined together to form a laminate having a fluid contacting surface. A plurality of spaced pockets is formed between the layers of material in the contacting surface. The layers of material are fluid permeable at the pockets whereby fluid may flow through the laminate at the pockets. The fluid contacting surface is fluid impermeable except for the pockets to require the fluid passing through the laminate to be confined to flowing through the pockets. Filter members are in the pockets for removing any contaminants from the fluid. Alternatively, additive materials such as powdered cream or sugar in the pockets dissolve in the fluid passing through the pockets to enhance the fluid.
