Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Structures for surface-enhanced nonplasmonic or hybrid spectroscopy

open access: yesNanophotonics, 2020
Absorption, scattering, and fluorescence are processes that increase with electric field intensity. The most prominent way to enhance electric field intensity is to use localized or propagating surface plasmon polaritons (SPPs) based on metallic ...

Ser japonês, ser nikkei, ser dekassegui

open access: yesRevista de Antropologia da UFSCar, 2014
O •luxo transnacional de brasileiros para o Japão trouxe várias disrupções dentro das comunidades nikkei espalhadas pelo Brasil, mas, mais do que isso: contorce e dobra planos hierárquicos seculares. Ancorado na lógica familiar do ie por vários séculos e aliando-se à incorporação dessa lógica com a fabricação da cidadania japonesa, temos no processo ...

Ser o no ser

open access: yesDerechos en Acción, 2020
El estudio que aquí se presenta se basa en el análisis crítico de la sentencia que condenó a cadena perpetua Reina Maraz Bejarano (en adelante RM) por el delito de homicidio agravado por el vínculo, para referirme luego a la sentencia que la absolvió.

Microdroplet fabrication of silver–agarose nanocomposite beads for SERS optical accumulation [PDF]

open access: yes, 2011
Microdroplets have been used as reactors for the fabrication of agarose beads with high uniformity in shape and size, and densely loaded with silver ions, which were subsequently reduced into nanoparticles using hydrazine.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Neopterin interactions with magic atom number coinage metal nanoclusters: A theoretical study

open access: yesPteridines
Metal nanoclusters (NCs) are novel materials with low cytotoxicity, high chemical stability, intense luminescence, etc. These characteristics are in great demand during biomarker detection and bioimaging.

Theory of hyperbolic stratified nanostructures for surface enhanced Raman scattering

open access: yes, 2017
We theoretically investigate the enhancement of surface enhanced Raman spectroscopy (SERS) using hyperbolic stratified nanostructures and compare to metal nanoresonators.
