AFINAL, ESTãO AS EMPRESAS PREPARADAS PARA A COMPETêNCIA?


A cascade of iron-containing proteins governs the genetic iron starvation response to promote iron uptake and inhibit iron storage in fission yeast.

Iron is an essential cofactor, but it is also toxic at high levels.In Schizosaccharomyces pombe, the sensor glutaredoxin Grx4 guides the activity of the repressors Php4 and Fep1 to mediate a complex transcriptional response to iron deprivation: activation of Php4 and inactivation of Fep1 leads to inhibition of iron usage/storage, and to promotion o

Are standardized caries risk assessment models effective in assessing actual caries status and future caries increment? A systematic review

Abstract Background Assessing caries risk is an essential element in the planning of preventive and therapeutic strategies.Different caries risk assessment (CRA) models have been proposed for the identification of individuals running a risk of future caries.This systematic review was designed to evaluate whether standardized caries risk assessment

The Role of Flow Rate and Fluid Alkalanity on Fine Particles Movement and Influencing the Petrophysical Properties of Reservoir Sandstone

Permeability decline related with fine migration is one of the most widespread phenomenon that occurs in most oil reservoirs.Fine migration is here intensive in sandstone reservoir, but frequently misinterpreted.Movement of fine particles might be problamatic to identify and even not easy to predict and interpret.The main goal of this study is to i
