摘要:
The invention provides methods of preparing nucleic acids, such as RNA molecules, of a defined size or range of sizes. The invention provides compositions, methods and kits for use in the production and preparation of small RNA molecules (including without limitation micro-RNA, siRNA, d-siRNA and e-siRNA) and other nucleic acids of various sizes.
摘要:
The invention provides methods and compositions related to the field of gene expression regulation. In particular, methods and compositions of the invention can be used to identify RNAi cleavage sites along a target RNA molecule. Methods and compositions of the invention may also be used to knockdown expression of nucleic acid molecules which encode reporters.
摘要:
The present invention is in the fields of biotechnology and molecular biology. More particularly, the present invention relates to cloning or subcloning one or more nucleic acid molecules comprising one or more type IIs restriction enzyme recognition sites. The present invention also embodies cloning such nucleic acid molecules using recombinational cloning methods such as those employing recombination sites and recombination proteins. The present invention also relates to nucleic acid molecules (including RNA and iRNA), as well as proteins, expressed from host cells produced using the methods of the present invention.

Rewarding a first classification of purchasers of digital media is provided. Such a classification may include initial purchasers (e.g., purchasers of new items) and secondary purchasers (e.g., purchasers of previously used items). A digital medium is played on a digital device and a notification is sent to a server. The server identifies the user of the digital device based on a unique device identifier associated with the digital device and a stored association of that digital device with the user. The user is determined to belong to the first classification of purchasers of the digital medium based on a unique identifier associated with the digital medium. The user, belonging to the first classification of purchasers, is provided with access to a reward that is not generally accessible to users belonging to a second classification. Users that are identified as belonging to the second classification may be offered a chance to upgrade their classification and access the reward.

A surgical device, and related method to aid in delivery by vaginal or cesarean section delivery to dislodge the fetal head when it has become wedged in the birth canal is provided. The device has a body and a handle for an operator to hold and brace against the mother, and a head plate with an inflatable bladder for gently applying force to the fetal head. The head plate is inserted into the birth canal and the bladder is filled with air or biocompatible fluid. The combination of insertion and inflation gently elevates the fetal head out of the birth canal into the pelvis to facilitate repositioning or extraction of the fetus. The device may have an adjustable neck to accommodate different anatomies and scenarios. The device may have sensors to monitor the health of both the neonate and the mother and to aid in the operation of the device.

An individual may wish to make a gift of digital media to a designated recipient. The digital media may be previously purchased by the individual or may be new, unused digital media purchased specifically as a gift for the recipient. The sender of the gift sends a gift notification. The sender is then verified to ensure that the sender is authorized to make the gift by matching an identifier of the digital media with an identifier associated with the sender. The digital media may be associated with a set of rights and privileges. Further rights and privileges associated with the digital media may be offered to the recipient.

摘要:
An automatic skin biopsy device that includes a drive unit and a variety of shapes and sizes of disposable cartridges. The device is capable of automatic extraction of a small and precisely located portion of skin having a shape similar to a wide canoe. A disposable cartridge is mounted onto and driven by the drive unit which incorporates at least one gear motor. In a preferred embodiment the gear motor in the drive unit drives, via gears and cams, two cutter blades in the disposable cartridge through separate curved paths to extract from the skin the generally wide canoe-shaped skin sample. Preferably another gear motor via gear and cam action produces back and forth oscillation of the blades to assure easy slicing of the skin tissue. The canoe-shape incision that is about 1 to 4 mm deep produces a good biopsy sample and the incision is easily closed with a medical staple or sutures. In preferred embodiments a stapler is provided as a part of the sample acquisition device. Materials used to fabricate the driver and the cartridge preferably transparent to permit accurate placement of the incision.
