Devices, systems and methods for treating medical conditions using cell therapy via body lumens. Localized delivery is achieved with the use of a stent-like expandable body seeded with cells. The expandable body is expanded to contact at least a portion of the inner walls of the body lumen and the cells, cellular products and/or other therapeutic agents are delivered to the surrounding tissue. The therapeutic benefit provided is dependent on the type of cells used and the features of the expandable body.

A system and method is described for saving power in a wireless network, using a physical layer address filtering protocol based on a partial address subset of the complete destination MAC address. The system comprises a PHY layer filtering protocol for generating the partial address and writing the partial address into a PHY layer header portion (e.g., PLCP header) of a sending station, or reading the partial address from the PHY layer header portion upon transmission of each frame. A receiving station receives and decodes these PHY layer header portion bits, in accordance with the protocol, and compares whether the subset of bits match that of the stations' own partial address. If a station finds a match, the station then continues further decoding the frame at PHY layer and send the complete frame to the MAC layer for further processing. The stations that do not have a match will not activate their MAC layer components. Thus, the stations of the network will avoid wasting power decoding a significant portion of the complete frame of other stations of the wireless local area networks and unnecessary MAC layer processing. When group addressed, control/management frames or other such frames are detected at the sending station, the address filtering protocol may be “disabled” using a partial address containing a predetermined value (e.g., all zeros).

The present inventors studied the effects of inhibiting the IL-6 signaling pathway on muscle cell growth. As a result, they discovered that, administering an IL-6 inhibitor can promote the adhesion, proliferation, and differentiation of satellite cells and therefore muscle regeneration.

Method and system for the analysis and source localization of the dynamical patterns in medical and health data, and linking such dynamical patterns with the individual's genetic and/or molecular data. The invention makes use of optimally positioned sensors (sensor arrays) providing input data for signal processing, time-series analysis, pattern recognition and mathematical modeling to facilitate dynamical tracking of systemic arterial pressure without a pressure cuff, local vascular activity, electrocardiographic (ECG), respiratory, physical, muscular, gastrointestinal and neural activity, temperature and other physiological/health data. The invention also facilitates separation of local signals (such as local aneurisms or local vascular activity) from non-local, central or systemic patterns (e.g. systemic blood pressure). In addition, the invention improves identification of dynamical patterns associated with a specific genotype/disorder for screening, personalized risk assessment, diagnosis and treatment control. The system can be implemented in a specialized processor, such as an ambulatory blood pressure monitor, Electrocardiograph, Holter monitor located outside subject's body or implanted inside the body, mobile/cell phone or Smart Phone/Personal Digital Assistant, computer or computer network (the Internet), including wireless or mobile network. The system can be also linked to the electronic health/medical records and other databases.

Cells present in adipose tissue are used to treat patients, including patients with PVD and related diseases or disorders. Methods of treating patients include processing adipose tissue to deliver a concentrated amount of stem cells obtained from the adipose tissue to a patient. The methods may be practiced in a closed system so that the stem cells are not exposed to an external environment prior to being administered to a patient. Accordingly, in a preferred method, cells present in adipose tissue are placed directly into a recipient along with such additives necessary to promote, engender or support a therapeutic benefit.

One embodiment of the present invention provides a system that facilitates displaying calendar information on a display. The system operates by displaying a status bar in a location on the display, which does not preclude other content from being displayed simultaneously. In addition, the system displays a calendar timeline including calendar information in the status bar, wherein one end of the calendar timeline represents a beginning of a displayed time period and an opposite end of the calendar timeline represents an end of the displayed time period. Moreover, the status bar is continuously viewable to a user regardless of what other content is being displayed on the display.

The invention relates to a method for preparing a small intestinal submucosa (SIS) soft tissue repair patch, and the soft tissue repair patch prepared by the method. The invention also relates to application of the soft tissue repair path to tissue repair.

A multi-party communication enhancer includes an audio data input adapted to receive voice data associated with a plurality of communication participants. A participant identifier included in the multi-party communication enhancer is adapted to distinguish the voice of a number of communication participants as represented within the received voice data. A cue generator, also included in the multi-party communication enhancer, is operable to generate a cue for each distinguished voice, with the generated cue being outputted in association with the corresponding distinguished voice.

Stem cell reprogramming genes cloned into a single sustained expression-type Sendai viral vector are shown to reprogram differentiated somatic cells into induced pluripotent stem (iPS) cells without integration of vector sequences into the host cell's genome. The genes are transduced into normal differentiated somatic cells via infection with recombinant Sendai virus. After expression of the reprogramming genes and subsequent induction of pluripotency, the vector genome RNA including the reprogramming genes is removed from the cell to establish an iPS cell that is genetically identical to the parent somatic differentiated cell thus reducing the risk of tumorigenic transformation caused by random integration of vector sequences into the host genome. The method promises to provide safe, autologous iPS cells that can be used for human cell replacement and regeneration therapeutic applications.

Stem cells, e.g. HSC and MSC-like stem cells, present in adipose tissue are used to treat diseases and disorders that would benefit from a hematopoietic stem cell transplant. Methods of treating patients include processing adipose tissue to deliver a concentrated amount of stem cells obtained from the adipose tissue to a patient. The methods may be practiced in a closed system so that the stem cells are not exposed to an external environment prior to being administered to a patient. Accordingly, in a preferred method, cells present in adipose tissue are placed directly into a recipient along with such additives necessary to promote, engender or support a therapeutic renal benefit.

A weight-controlled, motorized vehicle can be accelerated in either direction, steered, or decelerated without hand controls and without repositioning of a rider situated atop the vehicle. Like a skateboard, the vehicle is normally ridden by a rider standing upon a platform on top of the vehicle with one foot in front of the other. The vehicle is propelled forward when the rider increases weight on the front portion of the platform and backward when weight is increased on the rear portion. The vehicle is steered like a skateboard, by tilting the platform from side-to-side. An improved drive system utilizes a single front drive wheel to power and steer the vehicle. The drive system eliminates need of a flexible power transmission coupling such as a U-joint or constant-velocity joint. It also eliminates need of the differential mechanism normally required for two laterally spaced drive wheels.
