摘要:
Aspects of the present invention include methods and compositions for determining the number of individual polynucleotide molecules originating from the same genomic region of the same original sample that have been sequenced in a particular sequence analysis configuration or process. In these aspects of the invention, a degenerate base region (DBR) is attached to the starting polynucleotide molecules that are subsequently sequenced (e.g., after certain process steps are performed, e.g., amplification and/or enrichment). The number of different DBR sequences present in a sequencing run can be used to determine/estimate the number of different starting polynucleotides that have been sequenced. DBRs can be used to enhance numerous different nucleic acid sequence analysis applications, including allowing higher confidence allele call determinations in genotyping applications.

A hybrid prosthesis (100) for deployment in a body vessel includes a tubular stent body (110) comprising a wire (105) comprising a shape memory alloy, where the tubular stent body (110) has a self-expanding portion (110a) comprising a distal portion (115) of the wire (105) and a balloon-expandable portion (110b) comprising a proximal portion (120) of the wire (105). The shape memory alloy comprises an A f of less than 37°C in the self-expanding portion (110a) and an A s of greater than 37°C in the balloon-expandable portion (110b).

An endoluminal prosthesis system for a branched body lumen comprises a branch vessel prosthesis (11). The branch vessel prosthesis (11) is deployable within a branch vessel body lumen and comprises a stent (48) having a generally tubular body portion (33), a flareable proximal end portion (36), and a coupling portion (38) disposed intermediate the body portion and the flareable portion. The coupling portion is preferably more crush-resistant than the body portion.
摘要:
A method of increasing the probability and rate of seed germination, increasing vegetative biomass, and increasing water uptake in seeds, in which a seed is introduced to an effective concentration of carbon nanomaterial. The effective concentration of carbon nanomaterial is 10-200 μg/mL.

A stent graft deployment device assembly (10) has a cylindrical fixed handle (6) to be gripped and held by a user and an tubular release handle (30) extending through the fixed handle. The release handle can be moved through the fixed handle. The deployment device assembly has a pusher assembly and a sheath (18) to cover a stent graft on the pusher assembly. The pusher assembly is connected to the fixed handle and the sheath is connected to the release handle so that retraction of the release handle through the fixed handle causes the sheath to be retracted from the stent graft on the pusher assembly. The fixed handle has a rotator component (36) with internal first and second screw threads. The tubular release handle has an external screw thread (31) which engages with the first screw thread. The external screw thread (31) can extend along part, all or in segments along the release handle. A release clamp (48) on the pusher has pins which engage with the second screw thread. Movement of the rotator component with respect to the fixed handle first moves the tubular release handle with respect to the fixed handle and subsequently moves the release clamp on the pusher and thereby pulls the trigger wires.

A drive assembly (50, 100) for an introducer assembly (10) for the deployment of an implantable medical device (16) includes a sprung element (52) coupled to a yoke (56). The yoke (56) is coupled to a gripper element (58). The yoke (56) is coupled to a first handle unit (30) of the introducer (10). The sprung element (52) is coupled to a proximal handle unit (32). A brake element (66, 102) acts to prevent operation of the sprung element (52) when no manual force is being applied to retract a sheath (24) and the assembly (10). When manual retraction force is applied to the gripper element (58), the brake element (66, 102) releases the sprung element (52) so that the latter can apply a force assistance to assist in the retraction of the sheath (24) and thereby to assist in the deployment of a medical device.
摘要:
Aspects of the present invention are drawn to processes for moving a region of interest in a polynucleotide from a first position to a second position with regard to a domain within the polynucleotide, also referred to as a "reflex method". In certain embodiments, the reflex method results in moving a region of interest into functional proximity to specific domain elements present in the polynucleotide (e.g., primer sites and/or MID). Compositions, kits and systems that find use in carrying out the reflex processes described herein are also provided.
