O emprego de lipases como agentes de resolução cinética de enantiômeros em síntese orgânica: aspectos gerais sobre a influência do solvente

open access: yesQuímica Nova, 1999
In organic synthesis, lipases are the most frequently used biocatalysts. They are efficient stereoselective catalysts in the kinetic resolution of a wide variety of chiral compounds.

Structure of Sulfated Monosaccharides Studied by Quantum Chemical Methods

open access: yesMolecules, 2003
Ab initio and DFT analysis have been used to study of geometry of sulfated monosaccharides GlcN,6-SO3- and IdoA 2-SO3- in solvent. The computed low conformational barrier between the interconverting conformers of the IdoA 2-SO3- residue is in agreement ...

Single‐cell insights into the role of T cells in B‐cell malignancies

open access: yesFEBS Letters, EarlyView.
Single‐cell technologies have transformed our understanding of T cell–tumor cell interactions in B‐cell malignancies, revealing new T‐cell subsets, functional states, and immune evasion mechanisms. This Review synthesizes these findings, highlighting the roles of T cells in pathogenesis, progression, and therapy response, and underscoring their ...

Phase diagram of mixtures of colloids and polymers in the thermal crossover from good to $\theta$ solvent

open access: yes, 2014
We determine the phase diagram of mixtures of spherical colloids and neutral nonadsorbing polymers in the thermal crossover region between the $\theta$ point and the good-solvent regime.

Biological and technical complexities in analyzing extracellular vesicle immune interactions in B‐cell malignancies

open access: yesFEBS Letters, EarlyView.
Extracellular vesicles (EVs) mediate intercellular communication in tumor immune microenvironments. However, their role in B‐cell malignancies remains poorly defined, owing to biological complexity and technical challenges in EV isolation and analysis.

Intron‐oriented HTLV‐1 integration in an adult T‐cell leukemia/lymphoma cell line sustains expression of intact ift81 mRNA

open access: yesFEBS Letters, EarlyView.
In the adult T‐cell leukemia/lymphoma (ATL) cell line ED, the human T‐cell leukemia virus type 1 (HTLV‐1) provirus was integrated into the intron of the ift81 gene in the antisense orientation. Despite this integration, both the intact ift81 and the viral oncogene hbz were simultaneously expressed, likely due to the functional insufficiency of viral ...

New solvent options for in vivo assays in the Galleria mellonella larvae model

open access: yesVirulence, 2019
Experimentation in mammals is a long and expensive process in which ethical aspects must be considered, which has led the scientific community to develop alternative models such as that of Galleria mellonella.

Cyclic nucleotide signaling as a drug target in retinitis pigmentosa

open access: yesFEBS Letters, EarlyView.
Disruptions in cGMP and cAMP signaling can contribute to retinal dysfunction and photoreceptor loss in retinitis pigmentosa. This perspective examines the mechanisms and evaluates emerging evidence on targeting these pathways as a potential therapeutic strategy to slow or prevent retinal degeneration.

A Quantitative Theory of Mechanical Unfolding of a Homopolymer Globule

open access: yes, 2012
We propose the quantitative mean-field theory of mechanical unfolding of a globule formed by long flexible homopolymer chain collapsed in poor solvent and subjected to extensional deformation. We demonstrate that depending on the degree of polymerization

TRAF2 binds to TIFA via a novel motif and contributes to its autophagic degradation

open access: yesFEBS Letters, EarlyView.
TRAF family members couple receptor signalling complexes to downstream outputs, but how they interact with these complexes is not always clear. Here, we show that during ADP‐heptose signalling, TRAF2 binding to TIFA requires two short sequence motifs in the C‐terminal tail of TIFA, which are distinct from the TRAF6 binding motif.
