摘要:
In vivo biocompatible hydrogels to couple and transmit high intensity ultrasound for hemostasis and ablation during surgery, the hydrogels having 4-40 wt. % of a polymer comprising acrylates and the balance water. A group of hydrogels based on cross-linked methacrylate one of which is polyethyleneglycol methacrylate, can form rigid, low acoustic attenuation coupling members and are in vivo biocompatible. These coupling members consist of hydrogel formulations having mechanical and acoustic properties such that ultrasound transmission standoff members of various dimensions and structural configurations function as efficient ultrasound transmission media and devices within which the ultrasound beam can be transferred to a focal point at the end of the standoff or in close proximity to it.

An vivo biocompatible and bio-excretable lubricant and ultrasound coupling fluid or gel comprising polyvinylpyrrolidone (PVP) and/or polyvinyl alcohol (PVA). The inventive couplant fluid or gel comprises polyvinylpyrrolidone and/or polyvinyl alcohol solutions in water to which humectants such as alkylene glycols and/or polyalkylene glycols are added to achieve desired tactile and drying characteristics. Additionally, such fluids and gels may be prepared by addition of organic and inorganic cross-linkers.

A collapsible table is concealed and stored in the hollow chamber of an upholstered seat arm. The table is pivotally connected to the seat arm by a two-segment spar which supports the table in the extended position and is collapsible for returning the table to the stored position in the arm chamber. A handle is easily manipulable by a seat occupant for collapsing the spar and returning the table to its storage position. The outer upholstered panel of the arm carries the male member of a latch for pivotal movement of the panel to permit access to the chamber and extension of the table. The table carries a cup holder which is pivotal between concealed and extended positions and which is automatically returned to its concealed position by engagement with the front post of the arm when the table is returned to its storage position.

An electronic sign includes a planar lighting module emitting visible light. A cabinet supportingly engages the lighting module. An air chamber is between the cabinet and the lighting module. A vertical partition is within the air chamber and extends between a bottom wall and a top wall of the cabinet, and between the lighting module and a rear wall of the cabinet. The partition divides the air chamber into first and second sections. An electric fan is within the cabinet and transfers air from the first to the second section. The cabinet and/or the lighting module include a plurality of throughholes fluidly interconnecting the air chamber to ambient air. A first subset of the throughholes are more closely fluidly connected to the first section than to the second section. A second subset of the throughholes are more closely fluidly connected to the second section than to the first section.

Methods and systems for planarization of a die-to-wafer integration. A planarization coating may be applied to the die-to-wafer assembly, and a planarization plate may be used in the planarization process. The planarization plate may include perforations configured to allow a portion of the planarization coating to extrude through the planarization plate.

The present invention concerns implantable ocular devices for the sustained release of medication to the eye, and methods for manufacturing and using such devices. In one embodiment, the present invention provides a device comprising: (a) a body comprising a matrix of a prostaglandin and a silicone; (b) a parylene coating on the outer surface of the body; and (c) one or more pores extending from the outer surface of the parylene coating to the outer surface of the body.
摘要:
The present invention provides immunogenic and pharmaceutical compositions for the treatment and prevention of human papillomavirus (HPV)-associated cancers and in particular, cervical cancer. In particular, this invention relates to fusion proteins, and the nucleic acids encoding these fusion proteins, used to generate immune responses against HPV. Specifically, this invention provides for fusions of HPV E6 and E7 in which the E6 and/or E7 contains one or more mutations. These mutations abrogate the transformation activity of these oncogenic proteins and, thus, confer safety to the E6/E7 fusions. In addition, these fusions maintain or increase the immunogenic efficacy of E6 and E7. Any gene or protein delivery method can be used to deliver or package the immunogenic compositions of the present invention.
