摘要:
The present invention relates to a chimeric regulatory sequence with liver cell specificity. The chimeric regulatory sequence includes a proximal regulatory sequence and a distal enhancer 5 flanking region of human α-fetoprotein (AFP) gene. The chimeric regulatory sequence is useful in purified specific lineages, such as liver cells, from other cell lineages.
摘要:
The present invention discloses a method for improving growth and survival of single human embryonic stem cells. The method includes the step of obtaining a single undifferentiated HES cell; mixing the single undifferentiated cell with an extracellular matrix (ECM) to encompass the cell; and inoculating the mixture onto feeder cells with a nutrient medium in a growth environment. Therefore the single cells can survive, proliferate and grow in vitro.

In a system and method for controlling a virtual keyboard of an electronic device, the virtual keyboard is generated and displayed on a touch screen of the electronic device. The method sets an angle threshold value, a movement amplitude and a movement direction of the virtual keyboard for each tilting angle of the electronic device. When the electronic device is in an edit mode and displays a middle keyboard area of the virtual keyboard, the method records an initial tilting angle and read the tilting angle of the electronic device. The method calibrates the read tilting angle to acquire actual tilting angle according to the initial tilting angle, and confirms the movement amplitude and movement direction of the virtual keyboard according to the actual tilting angle. The virtual keyboard is controlled to move according to the confirmed movement amplitude and towards the confirmed movement direction.

The present application describes the use of low HER3 as a selection criterion for treating patients with a HER inhibitor, such as pertuzumab.It also describes the use of high HER2:HER3 ratio as a selection criterion for treating cancer patients, such as ovarian cancer patients, with a HER inhibitor, such as pertuzumab.In addition, the application describes the use of high HER3 as a selection criterion for treating cancer patients with a chemotherapeutic agent, for instance gemcitabine.

摘要:
In a general aspect, an apparatus for washing biological material is provided which includes an outer sleeve, and an inner sleeve disposed within the outer sleeve. The outer sleeve has an open end for receiving the biological material, and an opposed closed end. The inner sleeve is detachably and slidably positioned within the outer sleeve, and includes a first port for receiving and dispensing washing liquid, a second port defining a liquid flow path between an interior of the inner sleeve and an interior of the outer sleeve, and a filter disposed in the second port. The filter allows passage of washing liquid but not passage of the biological material therethrough. A chamber, formed between the filter and the closed end of the outer sleeve, is configured to permit flow of washing liquid via the filter while retaining the biological material therein.
