Abstract: A video monitoring system can include multiple collectors to receive video beacon data from multiple video monitoring interface modules. At least one beacon stream is connected to receive data from multiple collectors. A processing module receives the beacon stream and provides a real-time event stream used for real-time data analysis and a video view stream used for long-term data analysis.

Abstract: Provided herein are affinity agents comprising ligands that specifically bind adeno-associated virus. The affinity agents are useful for binding, isolation, and/or purification of adeno-associated virus. Further disclosed are amino acid sequences of binding motifs or polypeptides comprised by the ligands, and associated modifications of the binding motifs and/or polypeptides, as well as a method of making the affinity agents.

Abstract: An apparatus for use with a radio frequency generator and an indifferent electrode to treat tissue in a mammalian body includes a needle having a distal portion and being adapted for coupling to the radio frequency generator and a layer of insulating material extending around the needle but exposing a part of the distal portion of the needle. The exposed part of the needle is sized as a function of the thicknesses of the plurality of layers of tissue to facilitate placement of the distal portion of the needle in the plurality of layers by measuring impedance between the needle and the indifferent electrode.
