摘要:
The thermodynamics of self-assembling peptides may be altered to produce different morphologies. By altering environmental factors, initiation and propagation of self-assembly processes may be altered, thereby consequently altering the morphology of the resultant structure.

The present invention is an alert system and apparatus that interrupts the operation of sound producing and video display entertainment and communication devices and replaces the signals with an audible verbal annunciation and text message that overlays on the video displayed and initiates an alerting device or devices in connection with attracting the attention of hearing and/or visually impaired persons, persons who are not in close proximity to the area relating to the alert or by person who desire to be alerted by these mechanism.
摘要:
A decomposable thin film comprising a plurality of polyelectrolyte layers of alternating charge, wherein decomposition of the thin film is characterized by degradation of at least a portion of the polyelectrolyte layers.
摘要:
The invention relates, in part, to methods and compositions for the intracellular delivery of polysaccharides. In particular, the methods and compositions relate to the intracellular delivery of glycosaminoglycans, such as heparin. The invention in other aspects relates to the use of glycosaminoglycans for the treatment of proliferative disorders, such as cancer. The invention is still other aspects relates to improving cell viability. The invention also relates to the delivery of polysaccharides while avoiding unwanted effects of the polysaccharides. For example, heparin can be delivered while avoiding its anticoagulant effects.
摘要:
A drug delivery system comprising pH triggerable particles is described. The pH triggerable particles comprise and agent(s) to be delivered, which is encapsulated in a matrix comprising a pH trigger agent and a polymer. Agents including nucleic acids may be delivered intracellularly using the inventive pH triggerable particles. Upon exposure to an acidic environment such as the endosome or phagosome of a cell, the particles dissolve or disrupt due to protonation or an increase in solubility of the pH triggering agent. Pharmaceutical compositions and methods of preparing and administering these particles are also described. These particles may be particularly useful in genetic vaccination.
摘要:
A protective mesh system for distributing electrical power. The protective mesh system may include a body that supports and positions a protective mesh within its outer edges. The protective mesh may be of a single polarity and includes conductors and circuit opening devices. The protective mesh may provide for connecting to one or more power devices. One or more connectors may be electrically connected to the protective mesh and positioned along one or more of the edges of the body. The connectors may provide for connecting to an external power source.
摘要:
A magnetically-controlled connector for attaching a panel to a support member. The connector is configurable between locked and unlocked positions. In the locked position, an arm extends outward to engage with an exterior support member. In the unlocked position, the arm is retracted inward and is disengaged from the support member. The connector is configured to be movable between the positions using a magnetic actuator that is selectively moved into and out of proximity of the connector.
摘要:
A belt monitoring system employs a belt having at least one reinforcement member made from a conductive reinforcement material. A belt monitor is disposed in conjunction with the belt. The belt monitor comprises a field inductor excited by an applied signal. An electrical characteristic of at least a portion of the field inductor as influenced by changes in the electrical properties of the conductive reinforcement member is monitored in order to determine a physical condition of the conductive reinforcement member and thereby monitor a physical characteristic of the belt. This monitoring may be carried out by a sense inductor disposed adjacent or in conjunction with the field inductor.
