Incorporation of sludge from the cutting of ornamental rocks in cementitious ma...
Moreira, O.; Malheiro, R.; Jesus, C.; Camões, A.; Ribeiro, M.J.O desenvolvimento mundial impulsiona a procura por cimento e os desafios ambientais associados à sua fabricação preocupam os investigadores. O setor de cimento é o terceiro maior consumidor industrial de energia e o segundo maior emissor de CO2. Neste sentido, algumas medidas têm sido implementadas. Para além da redução da relação clínquer/cimento, a redução do consumo de cimento através da utilização de Materi...

Moreira, O.; Malheiro, R.; Jesus, C.; Camões, A.; Ribeiro, M.J.The development of the world drives the demand for cement and the environmental challenges associated with its manufacture concern researchers. The cement sector is the third largest industrial consumer of energy and the second largest emitter of CO2. In this sense, some measures have been implemented. In addition to reducing the clinker/cement ratio through use of composite cements, reducing cement consumption...
Effect of the particle size range of construction and demolition waste on the f...
De Rossi, A.; Ribeiro, M.J.; Labrincha, J.A.; Novais, R.M.; Hotza, D.; Moreira, R.F.P.M.This study seeks the valorization of industrial residues (fly ash and construction and demolition waste (CDW)) through the production of geopolymer mortars. The effect of the sand substitution by CDW and the influence of the particle size range of CDW fine aggregates on the fresh and hardened properties of the mortars were evaluated. Geopolymer mortars were produced using biomass fly ash waste and metakaolin as...
Insulin resistance is associated with tissue-specific regulation of HIF-1α and ...
Sacramento, J.F.; Ribeiro, M.J.; Rodrigues, T.; Guarino, Maria Pedro; Diogo, L.N.; Seiça, R.; Monteiro, E.C.; Matafome, P.; Conde, S.V.Chronic intermittent hypoxia (CIH) is a feature of obstructive sleep apnea (OSA). Whereas clinical stud-ies have demonstrated the association between OSA and insulin resistance, the molecular mechanismsbehind it are still unknown. Herein we investigated the effect of mild CIH on insulin sensitivity and weevaluated the changes in insulin and HIF signaling pathways that occur in CIH-induced insulin resistance.We ...
Hyperbaric Oxygen Therapy Improves Glucose Homeostasis in Type 2 Diabetes Patie...
Vera-Cruz, P.; Guerreiro, F.; Ribeiro, M.J.; Guarino M.P.; Conde, S.V.The carotid bodies (CBs) are peripheral chemoreceptors that respond to hypoxia increasing minute ventilation and activating the sympathetic nervous system. Besides its role in ventilation we recently described that CB regulate peripheral insulin sensitivity. Knowing that the CB is functionally blocked by hyperoxia and that hyperbaric oxygen therapy (HBOT) improves fasting blood glucose in diabetes patients, we ...
