A 6.1-to-41.5 GHz CMOS Low-Noise Amplifier for Wideband and Highly Linear Applications [PDF]
Journal of Electromagnetic Engineering and ScienceThis paper presents a CMOS low-noise amplifier (LNA) for wideband applications that require high linearity. A frequency staggering technique is employed to achieve a flat gain response over a wide frequency band. In the first stage, the LNA uses a common-

Peptide–LNA oligonucleotide conjugates
Organic & Biomolecular Chemistry, 2013 Although peptide-oligonucleotide conjugates (POCs) are well-known for nucleic acids delivery and therapy, reports on internal attachment of peptides to oligonucleotides are limited in number. To develop a convenient route for preparation of internally labeled POCs with improved biomedical properties, peptides were introduced into oligonucleotides via a

Amplification and Re-Generation of LNA-Modified Libraries
Molecules, 2012 Locked nucleic acids (LNA) confer high thermal stability and nuclease resistance to oligonucleotides. The discovery of polymerases that accept LNA triphosphates has led us to propose a scheme for the amplification and re-generation of LNA-containing ...

Locked nucleic acid inhibits amplification of contaminating DNA in real-time PCR
BioTechniques, 2005 Locked nucleic acid (LNA®) is a modified DNA with increased binding affinity for complementary DNA sequences. Our strategy was to use this property of LNA to inhibit undesired PCR amplification (e.g., from contaminating genomic DNA) in a cDNA-based assay.

Modulation of miR‐23b Wnt/β‐catenin Axis Strengthens Endothelial Barrier Properties
Advanced Science, EarlyView.Early blood‐brain barrier (BBB) disruption contributes to stroke and CNS disease pathology. miR‐23b was identified as a regulator of BBB integrity in brain endothelial cells. Inhibition of miR‐23b enhanced barrier‐associated properties, promoted repair‐related signaling, and reduced BBB leakage in experimental stroke models, supporting further ...
