Abstract: A power supply processing device includes three electric control valve groups, a positive output terminal and a conversion control switch group. The conversion control switch group includes a selection switch group configured to selectively connect the current valve control components in each electric control valve group to the positive output terminal or the phase output terminal, and a connection switch group configured to connect or disconnect a current path between two electric control valve groups connected one another. In such a way, both AC experiments and DC experiments of high voltage and large capacity may be performed to the connectors without changing experimental site and experimental equipment, thereby effectively reducing the experimental cost.

Abstract: The present disclosure relates generally to internet technology and more specifically to managing Top-level domain (TLD) name based on blockchain. An example method of managing Top-level domain name comprises the following steps: A. Using TLD nodes to form alliance network in the blockchain; B. Layering the system architecture in the alliance network to separate operations and data; and C. Reaching consensus among all nodes in the alliance network through consensus mechanism. A more effective and efficient consensus mechanism will increase the safety and reliability of the system and improve the efficiency of the system. Layering the system structure will ensure the efficiency and portability of the system.

Abstract: A method for extracting DNA from a specimen is provided which is cost-efficient, nontoxic to laboratory workers and is automation-compatible to meet high-throughput requirements in newborn screening and other nucleic acid applications. Methanol is added and evaporated at a high temperature to ensure the heme and other large proteins bind to the filter paper thus preventing them from going into solution during extraction and inhibiting later PCR reactions. A buffer and salt concentration is then added to each specimen to continue to bind the heme protein to the filter paper when the DNA is extracted from the filter paper at an optimal pH. The plate is then heated to release the DNA into the buffer without releasing excess heme protein which may inhibit PCR reactions.

Abstract: What is disclosed is a system and method utilizing an automation system for high throughput DNA extraction and PCR setup, a conventional thermal cycler, and a LIGHTTYPER™ instrument for post-PCR melting temperature analysis for beta-globin mutations. Melting temperature analysis is achieved through fluorescent resonance energy transfer (FRET) reaction using the LIGHTTYPER™ instrument. The assay is designed to simultaneously detect three common beta-globin mutations, S(A173T), C(G172A), and E(G232A), and can identify any of the eight possible genotypes in a single reaction: AA, AE, EE, AS, SC, SS, AC, and CC (A represents wild type allele).

Abstract: A newborn screening method is provided for detecting the causes of hereditary hearing loss. Patient specimen amplicons are synthesized, wherein the amplicon is an oligonucleotide specific to a gene selected from the group consisting of cytomegalovirus (CMV), mitochondria, and connexin 26 (Cx26). They are then spotted on a substrate and immobilized as a target for microarray production as wild type and mutated alleles are allowed to hybridize thereto and undergo image analysis.

Abstract: A method and an associated microarray for detecting hemoglobinopathies by DNA microarray analysis is disclosed for a newborn screening protocol. A fragment of the human beta-globin gene is amplified and immobilized on a glass substrate and is allowed to hybridize with fluorescent dye-labeled oligonucleotide probes matched to either wild type or mutant S, C, and E alleles of the beta-globin gene. The resulting hybridized microarray slide is scanned and analyzed to reveal normal gene sequence or single nucleotide polymorphisms.
