International Classification:

H04B 1/38

US Classification:

455558, 455415, 455418, 4554351

Abstract:

Systems, methods, and computer program products are for managing access to a femtocell coverage area. An exemplary method includes storing in a memory component a first identifier corresponding to a subscribed service of a communication device and a second identifier corresponding to a user of the communication device, and granting access to the femtocell coverage area using the second identifier.

Elixirin Corporation - Richmond CA

International Classification:

A61K 31/385
C07D 339/04

C12N 1/26

US Classification:

514440000, 435248000, 435261000, 549037000

Abstract:

This invention relates to dietary compositions and to methods for modifying cellular metabolism, metabolic production of reactive oxygen species and the resulting level of reactive oxygen species. The invention is drawn to a composition comprising a combination of carnitine, lipoic acid and polyphenol, which has the effect of enhancing metabolism and reducing oxygen species at the same time. When the composition is fed to older animals, the animals will have improved metabolism at the cellular level and a reduction of oxidative stress. The invention is also drawn to a method of oral administration of carnitine, lipoic acid and polyphenol to a mammalian host, at an effective dose necessary to affect enhanced metabolic processes and reduced oxygen species in animals including humans.

Appl. No.:

12/159827

Inventors:

John Kunich - San Leandro CA, US
Cheng Liu - Richmond CA, US

International Classification:

G01N 33/574
G01N 33/566

US Classification:

435 723, 435 72

Abstract:

Methods for detecting antibody dependent cellular cytotoxicity (ADCC) are described herein. The methods are label-free, and can be performed in real time on adherent cells. The methods can include, for example, (a) monitoring the impedance between electrodes on a non-conducting substrate that supports the growth of target cells in an assay medium; and (b) adding effector cells and an antibody that binds to the target cells to the assay medium; wherein any decrease in the impedance between the electrodes on the substrate following addition of the effector cells and the antibody is indicative of ADCC function having been effected in the assay medium.
