摘要: A method for attempting to fragment or comminute an object in a body using ultrasound includes producing a burst wave lithotripsy (BWL) waveform by a therapy transducer. The BWL waveform is configured to fragment or comminute the object. The BWL waveform includes a first burst of continuous ultrasound cycles and a second burst of continuous ultrasound cycles. A burst frequency corresponds to a frequency of repeating the bursts of the BWL waveform. The method also includes determining a cycle frequency f of the continuous ultrasound cycles within the first burst and the second burst based on a target fragment size D, where the cycle frequency is: f(MHz)=0.47/D(mm).

摘要: Provided herein, among other aspects, are methods and apparatuses for analyzing particles in a sample. In some aspects, the particles can be analytes, cells, nucleic acids, or proteins and contacted with a tag, partitioned into aliquots, detected by a ranking device, and isolated. The methods and apparatuses provided herein may include a microfluidic chip. In some aspects, the methods and apparatuses may be used to quantify rare particles in a sample, such as cancer cells and other rare cells for disease diagnosis, prognosis, or treatment.

摘要: Next Generation DNA sequencing promises to revolutionize clinical medicine and basic research. However, while this technology has the capacity to generate hundreds of billions of nucleotides of DNA sequence in a single experiment, the error rate of approximately 1% results in hundreds of millions of sequencing mistakes. These scattered errors can be tolerated in some applications but become extremely problematic when “deep sequencing” genetically heterogeneous mixtures, such as tumors or mixed microbial populations. To overcome limitations in sequencing accuracy, a method Duplex Consensus Sequencing (DCS) is provided. This approach greatly reduces errors by independently tagging and sequencing each of the two strands of a DNA duplex. As the two strands are complementary, true mutations are found at the same position in both strands. In contrast, PCR or sequencing errors will result in errors in only one strand. This method uniquely capitalizes on the redundant information stored in double-stranded DNA, thus overcoming technical limitations of prior methods utilizing data from only one of the two strands.

摘要: Methods and systems for acquiring and/or projecting images from and/or to a target area are provided. Such a method or system can include an optical fiber assembly which may be driven to scan the target area in a scan pattern. The optical fiber assembly may provide multiple effective light sources (e.g., via a plurality of optical fibers) that are axially staggered with respect to an optical system located between the optical fiber and the target area. The optical system may be operable to focus and/or redirect the light from the multiple light sources onto separate focal planes. A composite image may be generated based on light reflected from and/or projected onto the separate focal planes. The composite image may have an extended depth of focus or field spanning over a distance between the separate focal planes while maintaining or improving image resolution.
