EDUCAÇÃO, COMUNICAÇÃO E TECNOLOGIAS: UMA NOVA GEOMETRIA PARA OS DIFERENTES ESPAÇOS EDUCATIVOS

open access: yesRevista Diálogo Educacional, 2004
This article aims to explore the concepts related to a physical, a conceptual, and cyber spaces, proposing a new geometry able to represent how we operate in these different spaces.

Conceptual Neighborhood Graphs of Topological Relations in Z2

open access: yesISPRS International Journal of Geo-Information
Topological relations form the backbone of qualitative spatial reasoning and, as such, play a paramount role in geographic information systems. Three decades of research have provided a proliferation of sets of qualitative topological relations in both ...

A conceptual space for classical concepts

open access: yesSynthese
Abstract A core assumption of the conceptual spaces approach is that concepts, which are represented as regions in a space, have prototype structure. This may suggest that the framework cannot be successfully applied to the study of classical concepts based on definitions given by necessary and sufficient conditions.

Ionomycin suppresses cancer cell growth by disrupting mitochondrial transcription

open access: yesFEBS Open Bio, EarlyView.
In this study, we identify a new function for the selective Ca2+ ionophore, ionomycin, as an inhibitor of mitochondrial transcription. Both total and nascent RNA analyses revealed that ionomycin treatment reduces the transcription of mitochondrial genes.

ATZ‐1 promotes DNA replication efficiency to maintain normal meiotic function

open access: yesFEBS Open Bio, EarlyView.
Absence of ATZ‐1 interferes with meiotic DNA replication and cell cycle function via CHK‐1. This causes downstream defects associated with DNA damage and genomic integrity. Taken together, this study suggests that ATZ‐1 influences DNA replication efficiency and cell cycle function to maintain normal meiotic function.

Evaluating the effect of γ‐oryzanol on MASLD pathology using a medaka fish model

open access: yesFEBS Open Bio, EarlyView.
This study explores a liver disease called MASLD, which is increasing worldwide and can lead to serious damage. Researchers used medaka fish instead of rodents to test a food compound, γ‐oryzanol. Fish fed this compound had less liver fat and healthier gut bacteria.

KDAC6 alters cell morphology and motility through positive and negative modulation of F‐actin distribution

open access: yesFEBS Open Bio, EarlyView.
KDAC6 has been associated with cell motility and actin structures, but specific domain contributions are not established. The two catalytic domains have differential effects on motility and F‐actin regulation, affecting cortical F‐actin density, motility, stress fibers, and cell spreading.

Multimode Information Logistics for Conceptual Correspondence Monitoring

open access: yes
The paper addresses problems that arise in situations where conceptual correspondence has to be monitored. This type of monitoring requires manual, semiautomatic and automatic information processing and exposes high level of complexity.

In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols

open access: yesFEBS Open Bio, EarlyView.
Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

Dual native G‐quadruplex folding is associated with chromatin looping at the MYC locus

open access: yesFEBS Open Bio, EarlyView.
BG4‐detectable G‐quadruplex (G4) in HaCaT and NHEK keratinocytes identified folded and unfolded G4s enriched at promoters/TSSs and active enhancers, whereas unfolded G4s also overlapped weak/poised enhancers. At MYC–PVT1, 3C‐qPCR detected enhancer–promoter looping only when G4s were simultaneously folded at both regulatory elements under native ...
