摘要:
The invention provides methods and compositions for rapid, sensitive, and highly specific nucleic acid-based (e.g., DNA based) detection of human rhinovirus (HRV) in a sample. In general, the methods involve detecting a target nucleic acid having a target sequence of a conserved 5′ untranslated region of the HRV genome. The invention also features compositions, including primers, probes, and kits, for use in the methods of the invention.

Disclosed are methods of identifying a methicillin-resistant Staphylococcus aureus (MRSA) or methicillin-sensitive Staphylococcus aureus (MSSA) in a sample. The present invention provides a diagnostic method comprising modification of sequences of S. aureus by converting non-methylated cytosine residues ultimately into thymidine residues in the target nucleic acid. The invention further provides for the detection of modified sequences derived from the spa gene, the mecA gene, and the integrated SCCmec cassette of S. aureus.
摘要:
A dual frequency band inverted-F antenna used for communicating a low frequency signal and a high frequency signal includes a substrate, a ground metal, a vortical metal structure, a short circuit leg, a feeding leg, and a terminal micro strip. The ground metal and the terminal micro strip are formed on the lower surface of the substrate. The vortical metal structure, formed on the upper surface of the substrate, further has a short circuit end and an open circuit end. The short circuit leg connects electrically the short circuit end of the vortical metal structure with the ground metal. The feeding leg extends along a predetermined direction of the vortical metal structure to couple with a feeding circuit on the substrate. The terminal micro strip connects electrically to the open circuit end through a first conductive aperture. By increasing the encircling number of the vortical metal structure, the coupling effect is generated so that the equivalent wavelength of the high frequency signal can be longer, thus the resonance frequency thereof can be reduced, and so a first frequency can be still kept communicating at a lower frequency band and a second frequency can also be added for communicating at a higher frequency band.

The present invention generally relates to a molecular test of enterovirus, herpes simplex virus-1 and -2, and/or Varicella-Zoster virus, in order to identify patients with a viral infection, in particular a viral infection of the central nervous system. Accordingly methods and compositions are disclosed to determine the presence or absence of a viral pathogen in a biological sample comprising, wherein the target nucleic acids comprise the 5′ UTR of the enterovirus genome, UL29 of herpes simplex virus and gene 36 of Varicella-Zoster virus.
摘要:
An antenna structure has a substrate, having a first-side surface and a second-side surface. A first antenna substructure on the first-side surface has a first straight metal line and a second straight metal line. The second straight metal line joins to the first straight metal line, and is substantially perpendicular to the first straight metal line. A second antenna substructure disposed on the second-side surface has a metal plate, serving as a ground, wherein the first straight metal line is overlapping with the metal plate. An L-shape metal line protrudes from the metal plate, wherein a portion of the L-shape metal line is parallel and overlapping with the second straight metal line, and a portion of the L-shape metal line is parallel to the first straight metal line without overlapping.
摘要:
Described are approaches for the identification, detection, and quantification of nucleic acids in a biological sample. These methods are based, in part, on the elucidation of anomalous migration properties of short nucleic acid molecules when conjugated to a fluorescent label, such as fluorescein labels, such that a smaller nucleic acid reliably migrates slower than a larger nucleic acid under the same conditions of separation.
