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 ...

Fracionamento e disponibilidade de zinco por diferentes extratores em solos incubados com lodo de esgoto Zinc fractionation and availability by different extractants in sewage sludge-incubated soils

open access: yesRevista Brasileira de Ciência do Solo, 2005
O lodo de esgoto pode constituir um problema ambiental em virtude da necessidade de adequada disposição final. Dado seu elevado teor de matéria orgânica e nutrientes, tem-se considerado a possibilidade de sua utilização como fertilizante; entretanto ...

Photocarrier extraction in GaAsSb/GaAsN type-II QW superlattice solar cells

open access: yes, 2018
Photocarrier transport and extraction in GaAsSb/GaAsN type-II quantum well superlattices are investigated by means of inelastic quantum transport calculations based on the non-equilibrium Green's function formalism.

Substrate specificity of Burkholderia pseudomallei multidrug transporters is influenced by the hydrophilic patch in the substrate‐binding pocket

open access: yesFEBS Letters, EarlyView.
Multidrug transporters BpeB and BpeF from the Gram‐negative pathogen Burkholderia pseudomallei have a hydrophilic patch in their substrate‐binding pocket. Drug susceptibility tests and growth curve analyses using an Escherichia coli recombinant expression system revealed that the hydrophilic patches of BpeB and BpeF are involved in the substrate ...

Solanesol sequential extraction from tobacco leaves using microwave-ultrasound-assisted extraction (MUAE): MAE optimization

open access: yesCurrent Research in Green and Sustainable Chemistry
Solanesol (C45H74O) is an aliphatic terpene alcohol of nine isoprene units found in the tobacco plant (Nicotiana Tabacum L.). The long and complex biosynthetic pathway of solanesol makes the extraction method still the best way to obtain solanesol.

Function‐driven design of a surrogate interleukin‐2 receptor ligand

open access: yesFEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Jointly Multiple Events Extraction via Attention-based Graph Information Aggregation

open access: yes, 2018
Event extraction is of practical utility in natural language processing. In the real world, it is a common phenomenon that multiple events existing in the same sentence, where extracting them are more difficult than extracting a single event.

Two-phase wash to solve the ubiquitous contaminant-carryover problem in commercial nucleic-acid extraction kits [PDF]

open access: yes, 2020
The success of fundamental and applied nucleic acid (NA) research depends on NA purity, but obtaining pure NAs from raw, unprocessed samples is challenging.

Mechanisms of parasite‐mediated disruption of brain vessels

open access: yesFEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...
