摘要:
The present invention discloses novel compositions and methods for enhancing cardiac differentiation efficiency of stem cells or promoting ventricular and atrial cardiomyocytes formation from stem cells. The present invention also discloses the atrial and ventricular cardiomyocytes formed from the stem cells, and the uses of the cardiomyocytes for repairing cardiac injuries and screening for new medicaments for treating cardiac injuries.

A wedge and a method for determining the speed of sound in the wedge is disclosed. The wedge includes a reflecting wall and is configured such that a portion of the main ultrasonic signal transmitted by an ultrasonic transducer is reflected and travels through the wedge back to the ultrasonic transducer. The speed of sound can be determined based on the distance traveled by, and the time of flight of, the main ultrasonic signal and reflected ultrasonic signal in the wedge.

The present invention provides a plating apparatus with multiple anode zones and cathode zones. The electrolyte flow field within each zone is controlled individually with independent flow control devices. A gas bubble collector whose surface is made into pleated channels is implemented for gas removal by collecting small bubbles, coalescing them, and releasing the residual gas. A buffer zone built within the gas bubble collector further allows unstable microscopic bubbles to dissolve.

A calendar system handles meeting invitations. Associated entries are determined in a received meeting invitation of a calendar system. A forwarded invitation is generated according to the associated entries. An association is generated between the forwarded invitation and the meeting invitation. The forwarded invitation is then sent. In this way, the calendar distributes meeting arrangements relatively independently, so that meeting invitations and forwarded invitations can be managed relatively independently.

Techniques involving display of image search results are described. In one or more implementations, an image search result is displayed having a plurality of images. Responsive to selection of a particular one of the images, a filmstrip is displayed having a contiguous series of representations of at least a portion of the plurality of images, at least one of which is of the particular image, the particular image is displayed as disposed proximal to metadata associated with the image, and at least a portion of a webpage from which the particular image was obtained is displayed.

The present invention provides a method and system for implementing asynchronous portal pages, comprising a portlet monitor resident on a web browser and implemented with a script. When a user interacts with a portlet, the portlet monitor sends a XMLHTTP request to the portal server. The portal server obtains the corresponding web contents from the corresponding portlet based on the request. Then, the web contents are modified and the HTTP requests therein are redirected to XMLHTTP requests. The portlet monitor uses the modified web contents to refresh the web contents of the corresponding portlet in the portal page without reloading the whole portal page. Besides, after the user submits a request for a portlet, during waiting for the portlet being refreshed, the user may continue to interact with other portlets. Thus, the present invention has the abilities of partially refreshing and asynchronous communication.

An X-ray device which is especially applicable to the X-ray imaging for child at the age of 0-3 is provided. The X-ray device can use the X-ray tube (10) which uses the molybdenum target or rhodium target (12) to produce the soft X-ray by the tube voltage between 25 and 50 kV. The synchronous-exposing equipment contained in the X-ray device may identify the still status and the breath, pulse status suitable for exposure of the child, automatically select the optimal exposing time so that it can acquire a clear X-ray image through only one X-ray exposure, thus prevent the human body from the needless X-ray radiation caused by the multiple X-ray exposures, and also improve the service efficiency of the equipment.

The present invention provides a method and system for processing email attachments. The method includes determining that a local file is attached as an email attachment in the email; creating a corresponding relationship record of the email attachment and the local file; determining that the email attachment is modified; and replacing the local file with the modified email attachment according to the corresponding relationship record automatically.

A method for improving the performance and efficiency of a solar cell comprising the steps of: providing a plurality of silver nanowires and depositing a layer of the silver nanowires onto an emitter surface of the solar cell.
摘要:
Human embryonic stem cells form embryoid bodies in culture which contain differentiated human cells. Some of the human cells in embryoid bodies differentiate into cardiomyocytes. Here the biological and electrical characteristics of those cardiomyocytes are described with reference to the use of cardiomyocytes derived from human embryonic stem cells in drug screening protocols for mechanisms of cardiac toxicity.
