Chiral Microneedle Arrays With Terahertz Chiroptical Activity With Chiral‐Plasmon‐Chiral‐Phonon Resonance

Advanced Materials, EarlyView.
ABSTRACT Microneedle arrays (MNAs) is a rapidly emerging technology with broad biomedical applications in drug delivery and biosensing. With sub‐millimeter dimensions and periodicity, MNAs possess geometries nearly ideal for biomedical devices operating within the terahertz (THz) spectral window.

Ethnic variations in mammographic density: a British multiethnic longitudinal study.

, 2008
It is not known whether the 20-30% lower breast cancer incidence rates in first-generation South Asian and Afro-Caribbean women relative to Caucasian women in the United Kingdom are reflected in mammographic density.

C9orf72 arginine-rich dipeptide repeat proteins disrupt karyopherin-mediated nuclear import

eLife, 2020
Disruption of nucleocytoplasmic transport is increasingly implicated in the pathogenesis of neurodegenerative diseases, including ALS caused by a C9orf72 hexanucleotide repeat expansion. However, the mechanism(s) remain unclear.

3D Printing of Stretchable, Compressible and Conductive Porous Polyurethane for Soft Robotics

Advanced Materials Technologies, EarlyView.
A 3D‐printable porous dopamine‐polyurethane acrylate elastomer results in conductive, stretchable, and compressible structures that can be metallized in situ through catechol‐mediated silver reduction. The resulting material function as both compliant soft robot with a and strain sensors without complex assemblies, enabling fully 3D‐printed soft ...

Dynamics of DNA replication loops reveal temporal control of lagging-strand synthesis [PDF]

, 2009
In all organisms, the protein machinery responsible for the replication of DNA, the replisome, is faced with a directionality problem. The antiparallel nature of duplex DNA permits the leading-strand polymerase to advance in a continuous fashion, but ...

Optimization of Competitor Poly(dI-dC)•Poly(dI-dC) Levels is Advised in DNA-Protein Interaction Studies Involving Enriched Nuclear Proteins

BioTechniques, 1996
Procedures used for investigating DNA-protein interactions, such as the electrophoretic mobility shift assay (EMSA) or DNasel footprinting, require that exogenous nucleic acids (or synthetic equivalents) be added to the reaction mixture to prevent or ...

Helicoverpa armigera nucleopolyhedrovirus occlusion-derived virus-associated protein, HA100, affects oral infectivity in vivo but not virus replication in vitro

, 2011
ORF100 (ha100) of Helicoverpa armigera nucleopolyhedrovirus (HearNPV) has been reported as one of the unique genes of group II alphabaculoviruses encoding a protein located in the occlusion-derived virus (ODV) envelope and nucleocapsid.

Autoregulation of poly(A)-binding protein synthesisin vitro

Nucleic Acids Research, 1995
The poly(A)-binding protein (PABP), in a complex with the 3'poly(A) tail of eukaryotic mRNAs, plays important roles in the control of translation and message stability. All known examples of PABP mRNAs contain an extensive A-rich sequence in their 5' untranslated regions.
