Abstract: An electroporation apparatus has an electroporation probe terminals for linking with electrodes. A foam is injected at the treatment site to displace blood rather than mixing with it, increasing the contact time of a higher concentration of active agent with the tissue and thus resulting in greater efficacy. With foam solutions, a lower concentration of agent can be used to obtain the same therapeutic effect as in their liquid counterpart, reducing the prevalence of side effects associated with higher concentrations. A foam solution compared to an equivalent liquid solution enables more efficient cell electroporation particularly where bipolar pulses have been employed by mitigating an increase in tissue conductivity as would normally be observed with a comparable liquid solution. A more efficient cell permeabilisation would result in better results where electroporation is being delivered alone or as a tool to aid in the uptake of molecules into the cell.

Abstract: The invention is a method for the late introduction of inert particulate additives via a reactive carrier to achieve a polyester resin that is capable of being formed into low-haze, high-clarity bottles possessing reduced coefficient of friction. The invention is also a polyester resin that includes between about 20 and 200 ppm of an inert particulate additive, such as surface-modified talc or surface-modified calcium carbonate.

Abstract: The present invention relates to slow-crystallizing, titanium-catalyzed polyethylene terephthalate resins that are useful for making high-strength, high-clarity bottles that possess improved resistance to stress cracking and thermal creep. The polyethylene terephthalate resins possess improved reheating profiles and are especially useful for making polyester articles that have exceptional clarity, dimensional stability, and thermal stability.

Abstract: The present invention relates to methods of making titanium-catalyzed, polyethylene terephthalate resins, preforms, and bottles having reduced comonomer substitution.

Abstract: The invention is a method for the late introduction of additives into polyethylene terephthalate. The method employs a reactive carrier that functions as a delivery vehicle for one or more additives. The reactive carrier reacts with the polyethylene terephthalate, thereby binding the reactive carrier in the polyethylene terephthalate resin and preventing the emergence of the reactive carrier and additives from the polyethylene terephthalate during subsequent thermal processing.

Abstract: The present invention relates to slow-crystallizing polyethylene terephthalate resins that possess a significantly higher heating crystallization exotherm peak temperature (TCH) as compared with those of conventional antimony-catalyzed polyethylene terephthalate resins. The polyethylene terephthalate preforms of the present invention, which possess improved reheating profiles, are especially useful for making polyester bottles that have exceptional clarity and that retain acceptable dimensional stability upon being hot-filled with product at temperatures between about 195° F. and 205° F.

Abstract: A slip-on, insulating and decorative cover for bicycle safety helmets is provided by which bicycle helmets are provided with an overall covering complete with integral ear flaps. The ear flaps can be folded down to protect the ears and keep them warm in cold weather. The ear flaps have slots in them, thru which the helmet straps are routed. The decorative cover is readily attached and easily removed from the bike helmet to allow for removal during warm weather or for washing.
