International Classification:

G11B 5/127
G11B 21/21
G11B 5/39

US Classification:

360323, 3602353, 2960314

Abstract:

According to an embodiment of the present invention, a slider design is presented that provides improved protection for the head/sensor of the slider. In one embodiment, the design of the slider is such that ESD protection is provided during the slider wafer process, the “back-end” processes (e. g. , when the completed slider/head is incorporated into an HGA), and during operation in a disk drive or the like. In this embodiment, a conductive film is provided that surrounds the insulating-material slider substrate. The conductive film provides a grounding path during the wafer fabrication processes. This conductive layer may be further patterned during head fabrication to provide a ground path for back-end fabrication processes. A conductive stripe may be added for discharging debris in the slider-to-disk interface.

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.

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.
