Abstract:
Swellable particles for delivery of a drug or other working agent to the pulmonary system are provided. The swellable particles include a dehydrated (dry) aerodynamic particle diameter of 5 μm or less to enable delivery to the respiratory tract, such as for example to the tracheo-bronchial airways of the upper respiratory tract and/or to the alveolic regions of the deep lung, and a hydrated particle diameter that is greater than 6 μm volume mean diameter to retard or prevent their phagocytosis by the macrophages present in airways of the respiratory tract.
Abstract:
According to various embodiments, the present teachings relate to Generalized Transverse Bragg Waveguides (GTBW) that can include an a dielectric core having an index of refraction n1 and an optical axis. The optical waveguide can further include a media having an index of refraction n2 bounding a top surface and a bottom surface of the dielectric core, wherein n2
Abstract:
Internal reflection infrared waveguides having enhanced surface sensitivity and methods for using them are provided. In various embodiments, the internal reflection infrared waveguides can include a multiple internal reflection (MIR) crystal that is substantially transparent to mid-infrared light. The top surface of the MIR crystal can further include a plurality of nanochannels that extend from the top surface of the MIR crystal into the MIR crystal.
Abstract:
The present invention provides a general approach for G protein coupled receptors that may be used to define agonists and antagonists, and the specificity of receptor coupling to G protein subunits. Methods of the present invention use small volumes (microliters) and are compatible with high throughput flow cytometry. When assays of the present invention are multiplexed, the specificity of the interactions of a receptor with many G proteins may be determined simultaneously.
