International Classification:

C12Q 1/70
C07H 21/04

US Classification:

435 5, 536 2432

Abstract:

This disclosure relates to compositions and methods of their use in detection and identification of a chordopoxvirus in a sample, such as diagnosis of an infection in a subject. The compositions and methods allow for detection and identification of all non-avian low-GC content chordopoxviruses, identification of most known high-GC content chordopoxvirus, and species-specific detection of Canarypox virus, Fowlpox virus, and Sealpox virus.

Appl. No.:

13/647360

Inventors:

Yu Li - Johns Creek GA, US

International Classification:

A63B 21/00

US Classification:

482128, 482133

Abstract:

A chair-like exercising apparatus comprises a back, a seat, front legs, rear legs, and resistance element(s) which provide a broad range of resistance force adjustable by the user for the back extension exercise. The chair back pivotally connects to the rear legs directly, and pivotally connects to the front legs or rear legs through the resistance element(s). The resistance element comprises a compress-coil-spring cylinders (or constant-force-spring devices) and the cylinder holders (or the device holders). The resistance level of the back extension exercise is adjusted by switching the interchangeable compress-coil-spring cylinders (or constant-force-spring devices) of appropriate loads inside the cylinder holders (or device holders). A user sits on the chair and sway backward to perform back extension exercise after selecting an appropriate resistance level based on his/her physical condition. The apparatus is simple, affordable and can be used as a regular chair in its locked position. A regular back extension exercise with proper resistance force strengthens the low back muscles (erector spinae), improves and prevents the low back pain symptoms.

Inventors:

Yu Jin Li - Norco CA, US

Assignee:

IP POWER HOLDINGS LIMITED - Hong Kong

International Classification:

E04B 1/344
E04H 1/12

Abstract:

A folding shed may include a roof portion, a lateral portion and a bottom portion, said lateral portions forming two lateral sides of the shed that connects the roof portion and the bottom portion. Each roof portion, lateral portion and bottom portion includes a plurality of connecting units and hinge units, and each hinge unit is configured to pivotally connect with a longitudinal side of one connecting unit and pivotally connect with the other longitudinal side of an adjacent connecting unit. At least one hinge unit is configured to pivotally connect a corresponding connecting unit in the roof portion and a corresponding connecting unit in the lateral portion, and at least another hinge unit is configured to pivotally connect a corresponding connecting unit in the lateral portion and a corresponding connecting unit in the bottom portion.

International Classification:

C12Q 1/70
C12Q 1/6876

Abstract:

A real-time reverse transcriptase-polymerase chain reaction (RT-PCR) assay that utilizes multiplex primers and probes with degenerate nucleotides to detect divergent species of lyssavirus is described. The probes used in the RT-PCR assay target a highly conserved region at the 5′ end of the lyssavirus genome and are modified with either a minor groove binder (MGB) or locked nucleic acid (LNA) nucleotides to increase their melting temperature. The described assay detects all known lyssavirus species with a sensitivity and specificity superior to traditional hemi-nested PCR and the direct fluorescent antibody (DFA) test.

IP POWER HOLDINGS LIMITED - Hong Kong

International Classification:

A47B 23/04
A47B 9/16

Abstract:

A supporting rack may include a supporting surface, a base, a side supporting member, a center supporting member and a position adjusting unit. In one embodiment, the side supporting member has two side supporting arms, and an upper end of each side supporting arm is pivotally connected with an upper locking unit on one side of the supporting surface and a lower end thereof is pivotally connected to a corresponding side of the base. More specifically, the lower end of each side supporting arm is also connected to a lower locking unit on the base, which is configured to provide not only a stronger support for the supporting surface, but also lock the lower end of the side supporting arms. Similarly, each side supporting arm can be locked through the upper locking unit at a predetermined position according to the user's preference.

Inventors:

Yu LI - Johns Creek GA, US

International Classification:

A61M 3/02

Abstract:

A portable contact-washing device allows a user to wear a single-use finger cover for contact washing of rectal area using water that is delivered to the finger pad area through micro tubing by a mini water pump. This contact wash uses a limited amount of water for a sufficient hygienic wash to the rectal area after a bowel movement without causing irritation which is often associated of using toilet paper. The contact washing process is efficient and requires a small volume of water, and the contact-washing device is highly portable and easy to use outside of home. The finger cover may be made of biodegradable material and will be discarded after the use.
