In spermatozoa, Stat1 is activated during capacitation and the acrosomal reaction
(2007)
A role for sperm-specific proteins during the early embryonic development has been suggested by a number of recent studies. However, little is known about the participation of transcription factors in that stage. Here, we ...
Analytical approach to the reaction cross section of the fusion of protonswith boron isotopes aimed at cancer therapy
(Pergamon-Elsevier Science Ltd, 2019-05-05)
In recent years, the nuclear reaction known as proton-boron fusion has been thoroughly investigated, because it has been proposed as a suitable agent capable of significant improvements in cancer therapy with protons. ...
Statistics and kinetics of single-molecule electron transfer dynamics in complex environments: A simulation model study
(American Institute of Physics (AIP), 2008-12-14)
Dynamics of the environments of complex systems such as biomolecules, polar solvents, and glass plays an important role in controlling electron transfer reactions. The kinetics is determined by the nature of a complex ...
Movement behaviour determines competitive outcome and spread rates in strongly heterogeneous landscapes
(2018-09-01)
Classical models for biological invasions were single-species models in homogeneous landscapes, but most invasions happen in the presence of interacting species and in heterogeneous environments. The combination of spatial ...

Synthesis of benzylidenecycloalkan-1-ones and 1,5-diketones under Claisen–Schmidt reaction: Influence of the temperature and electronic nature of arylaldehydes
(Taylor & Francis, 2017-12)
Herein, we present the results of the influence of reaction temperature and the electronic nature of arylaldehydes in the reactions of benzocycloalkan-1-ones and arylaldehydes under classical Claisen–Schmidt condensation ...
Reaction kinetics formulation with explicit radiation absorption effects of the photo-Fenton degradation of paracetamol under natural pH conditions
(Springer Heidelberg, 2021-01)
The degradation of paracetamol (PCT) in an aqueous medium using the Fenton and photo-Fenton reactions was investigated. The aim of this research was the development of a kinetic model based on a reaction mechanism, which ...
Influence of the oxidation state of palladium nanoparticles on carbon coupling and bioorthogonal uncaging reactions
(2021)
O presente trabalho visou a compreensão do modo de ação de nanopartículas de paládio na mediação de reações de acoplamento carbono-carbono do tipo alquenilação de arila e em reações de clivagem bio-ortogonal visando o ...
