[NOTA DE PESQUISA] A INFLUÊNCIA DO MODO ANULAR SUL SOBRE O CICLO DO CARBONO NO OCEANO SUL: UMA BREVE REVISÃO DO CONHECIMENTO ATUAL (THE INFLUENCE MODE OF VOID SOUTH ON CARBON CYCLE IN THE OCEAN SOUTH A BRIEF CURRENT KNOWLEDGE REVIEW)

open access: yesRevista Brasileira de Climatologia, 2016
Descrevemos resumidamente o estado atual do conhecimento sobre a influência do Modo Anular Sul (SAM) sobre o Ciclo do Carbono Global no Oceano Sul.  Mostramos que estudos recentes indicam que o SAM está tornando mais positivo o que provavelmente alterará

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

open access: yesFEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Ritmos enredados da vida em Dakar. Sujeito, comunidade e tempo em La poubelle (1984), de Pape Pathé Diop

open access: yesRevista Contracampo, 2017
O presente trabalho demonstra a partir da análise do romance La poubelle (1984) de Pape Pathé Diop que a descrição de estruturas e funções da cidade do Sul global requer não apenas categorias espaciais, mas também temporais.

The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Gauge Theory Model of the Neutrino and New Physics Beyond the Standard Model

open access: yes, 2012
Majorana features of neutrinos and SO(3) gauge symmetry of three families enable us to construct a gauge model of neutrino for understanding naturally the observed smallness of neutrino masses and the nearly tri-bimaximal neutrino mixing when combining ...

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

open access: yesFEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

open access: yesFEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...
