摘要:
Methods of identifying a fusion inhibitor and inhibitors of gp41-mediated membrane fusion are disclosed. The methods comprise, for example, providing a first helical polypeptide comprising a sequence of IQN17 (SEQ ID NO: 1); providing a second helical polypeptide of 34 or less than 34 amino acids comprising the amino acid sequence W-X1-X2-W-X3-X4-X5-I, wherein X1, X2, X3, X4, and X5 are each independently chosen from any amino acid except proline; measuring, by capillary zone electrophoresis, the degree of complex formation between these peptides; and comparing the measured degree of complex formation to the degree in the presence of a test composition.

摘要:
The present invention relates to C34 peptide derivatives that are inhibitors of viral infection and/or exhibit antifusogenic properties. In particular, this invention relates to C34 derivatives having inhibiting activity against human immunodeficiency virus (HIV), respiratory syncytial virus (RSV), human parainfluenza virus (HPV), measles virus (MeV), and simian immunodeficiency virus (SIV) with long duration of action for the treatment of the respective viral infections.

Methods for isothermal titration calorimetry analysis of the binding affinity of protease inhibitors to plasma proteins. A method that can quantitatively calculate free drug concentrations of protease inhibitors in human plasma, as well as a method to calculate therapeutic amounts and dosage regimens. Furthermore, the present invention provides a method that can calculate the effect of plasma proteins on the antiviral activity (EC50 values) of protease inhibitors from their binding affinities to plasma proteins. The present invention provides as well a method that can evaluate the in vivo anti-HIV efficacy of PIs in human plasma.
摘要:
A proppant comprises a particle and a polycarbodiimide coating disposed on the particle. The polycarbodiimide coating comprises the reaction product of a polymeric isocyanate and a monomeric isocyanate, in the presence of a catalyst. A method of forming the proppant comprises the steps of providing the particle, providing the polymeric isocyanate, providing the monomeric isocyanate, providing the catalyst, reacting the polymeric isocyanate and the monomeric isocyanate in the presence of the catalyst to form the polycarbodiimide coating, and coating the particle with the polycarbodiimide coating.
摘要:
An implantable, substantially isodiametric, low resistance implantable lead having at least one electrode positioned in a stimulation/sensing portion of the lead as well as a method of manufacturing the same. At least the stimulation/sensing portion is unitized through partially surrounding and supporting insulation and conductive element(s) of the stimulation/sensing portion with a fused matrix of material having mechanical properties consistent with a body of the lead.

In one embodiment, a method electrically stimulates an area in a spinal disc. The method comprises: implanting at least one steerable lead at a placement site for stimulating a spinal disc such that the lead is disposed exterior and immediately adjacent to and circumferentially along an annulus of the spinal disc, the at least one lead including a plurality of electrodes distributed along a majority of a circumference of the annulus; connecting the lead to a signal generator; and generating electrical stimulation pulses using the generator to stimulate targeted portions of the spinal disc, wherein the stimulation of the targeted portion of the spinal disc sufficiently stimulates nerve tissue within the spinal disc to prevent communication of pain signals originating in the spinal disc without damaging tissue of the spinal disc.

A IP telephony service allows customers to form user groups. A user group is established by collecting a plurality of identifiers that are associated with members of a group, and associating the member identifiers with a group identifier. The member identifiers could be telephone numbers of telephony devices for each of the members, or device IDs of IP telephony devices for members of the group. The group identifier could be any type of identifier, and in some instances, the group identifier could be a telephone number.
摘要:
A IP telephony service allows customers to form user groups. Each user group can include multiple members, each of whom have their own telephony device. When a member of a user group sends a messages to another member of the user group, the message is posted to a group message board so that all members of the group can view the message. This could include sending information to each of the telephony devices for all members of the group so that each telephony device could display the message on a display screen. The displayed messages could also indicate who sent each message and to whom each message was directed. As a result, each member of the group can view messages passing back and forth between all members of the group.
摘要:
Described are techniques for detecting data collisions between a first portion and a second portion of an application executing on a computer, the first portion and the second portions executing concurrently with respect to each other. While the first portion and second portion are executing, before the first portion accesses a memory location shared by the first portion and the second portion, a value stored in the memory location is captured and the first portion is delayed. While the second portion continues to execute the first portion is delayed. After a period of the first portion having been paused or slowed, the current content of the memory location is compared with the captured content to determine if there is a data collision. The first and second portions may be threads, and the capturing, delaying, and determining may be performed by code inserted to the application after it has been compiled.
