A física clássica de cabeça para baixo: como Einstein descobriu a teoria da relatividade especial
Revista Brasileira de Ensino de FísicaAlbert Einstein por duas vezes alterou de maneira profunda nossos conceitos de espaço e tempo com a sua teoria da relatividade: primeiro no âmbito da teoria especial de 1905 e depois com a teoria geral de 1915.

Social context prevents heat hormetic effects against mutagens during fish development
FEBS Letters, EarlyView.This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

The Particle Problem in the General Theory of Relativity
, 1935 The writers investigate the possibility of an atomistic theory of matter and electricity which, while excluding singularities of the field, makes use of no other variables than the g&„of the general relativity theory and the p„of the Maxwell theory.

miRNA‐29 regulates epidermal and mesenchymal functions in skin repair
FEBS Letters, EarlyView.miRNA‐29 inhibits cell‐to‐cell and cell‐to‐matrix adhesion by silencing mRNA targets. Adhesion is controlled by complex interactions between many types of molecules coded by mRNAs. This is crucial for keeping together the layers of the skin and for regenerating the skin after wounding.

The relative trace formula in analytic number theory [PDF]
arXiv, 2019 We discuss a variety of applications of the relative trace formula of Kuznetsov type in analytic number theory and the theory of automorphic forms.

FEBS Letters, EarlyView.Spot‐14 and Spot‐14R play distinct roles in regulating metabolism in brown and beige adipocytes. While both influence lipid and glucose pathways, Spot‐14 uniquely controls thermogenic gene expression. This dual regulation balances energy storage and heat production, highlighting potential therapeutic targets for obesity and metabolic disorders. Spot 14

Relative e-spectra and relative closures for families of theories [PDF]
arXiv, 2017 We define the notions of relative $e$-spectra, with respect to $E$-operators, relative closures, and relative generating sets. We study properties connected with relative $e$-spectra and relative generating sets.

Hundres Years of Theory of Relativity
Advances in Electrical and Electronic Engineering, 2005 In 2005, all civilised worl will remind the 100 years anniversary of Publishing the original work on special theory of relativity by Albert Einstein. This contribution is a brief review of its principial ideas in the field of electrodynamics.

Charged black hole and radiating solutions in entangled relativity
European Physical Journal C: Particles and Fields, 2021 In this manuscript, we show that the external Schwarzschild metric can be a good approximation of exact black hole solutions of entangled relativity.

FEBS Letters, EarlyView.The enzyme 5‐lipoxygenase (5‐LOX) catalyzes the first step in the biosynthesis of leukotrienes (LTs) involved in inflammatory pathophysiology. After cellular stimulation, 5‐LOX translocates to the nucleus, interacting with the 5‐LOX‐activating protein (FLAP) to form LTA4 from arachidonic acid (AA).
