Universally Coupled Massive Gravity, II: Densitized Tetrad and Cotetrad Theories

, 2011
Einstein's equations in a tetrad formulation are derived from a linear theory in flat spacetime with an asymmetric potential using free field gauge invariance, local Lorentz invariance and universal coupling.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

On the energy of homogeneous cosmologies

, 2008
An energy for the homogeneous cosmological models is presented. More specifically, using an appropriate natural prescription, we find the energy within any region with any gravitational source for a large class of gravity theories--namely those with a ...

Effective therapeutic targeting of CTNNB1‐mutant hepatoblastoma with WNTinib

Molecular Oncology, EarlyView.
WNTinib, a Wnt/CTNNB1 inhibitor, was tested in hepatoblastoma (HB) experimental models. It delayed tumor growth and improved survival in CTNNB1‐mutant in vivo models. In organoids, WNTinib outperformed cisplatin and showed enhanced efficacy in combination therapy, supporting its potential as a targeted treatment for CTNNB1‐mutated HB.

The Dark Tetrad in the prediction of self-reported and behavioural risk-taking

Australian Journal of Psychology, 2021
Objective The explanatory power of the Dark Tetrad of personality (i.e., sub-clinical traits of sadism, psychopathy, narcissism and Machiavellianism) in the prediction of risk-taking behaviours is yet to be determined.

Modifying the theory of gravity by changing independent variables

, 2018
We study some particular modifications of gravity in search for a natural way to unify the gravitational and electromagnetic interaction. The certain components of connection in the appearing variants of the theory can be identified with electromagnetic ...

Exploiting metabolic adaptations to overcome dabrafenib treatment resistance in melanoma cells

Molecular Oncology, EarlyView.
We show that dabrafenib‐resistant melanoma cells undergo mitochondrial remodeling, leading to elevated respiration and ROS production balanced by stronger antioxidant defenses. This altered redox state promotes survival despite mitochondrial damage but renders resistant cells highly vulnerable to ROS‐inducing compounds such as PEITC, highlighting redox

O contágio emocional na Dark Tetrad

, 2022
A Dark Tetrad (DT) tem vindo a ser associada a défices na capacidade empática, sobretudo no que respeita à empatia afetiva. Como parecem ter uma empatia cognitiva preservada, sujeitos com traços DT parecem discernir acerca do estado emocional dos outros mantendo-se frios e distantes desses estados, ou seja, parecem revelar-se menos permeáveis ao ...

Violation of causality in $f(T)$ gravity

, 2017
[Abridged] In its standard formulation, the $f(T)$ field equations are not invariant under local Lorentz transformations, and thus the theory does not inherit the causal structure of special relativity.
