3. Marsdenia tenacissima extract alters crucial metabolites in cancer, determined by 1 H NMR based metabolomics approach
ABSTRACT Altered metabolites level in the biosystems, is the potential cause of cancer, the primary reason of alteration of metabolism is change in nutrient consumption and waste excretion, as a result genetic mutation leads to cancer initiation and progression. Aberration of specific metabolites such as fumarate, succinate, 2-hydroxyglutarate may alter cell

4. Cross-cultural adaptation of the Brazilian version of the Dentine Hypersensitivity Experience Questionnaire (DHEQ-15)
Abstract The dentine hypersensitivity (DH) is able to impair the oral health related quality of life (OHRQoL). However, there isn't any specific validated questionnaire to be used in Brazil. The objective was to adapt and to validate the English version of the Dentine Hypersensitivity Experience Questionnaire (DHEQ-15) for use in Brazil. DHEQ-15 was cross-cu

6. Dexterous hand gestures recognition based on low-density sEMG signals for upper-limb forearm amputees
Abstract Introduction Intuitive prosthesis control is one of the most important challenges in order to reduce the user effort in learning how to use an artificial hand. This work presents the development of a novel method for pattern recognition of sEMG signals able to discriminate, in a very accurate way, dexterous hand and fingers movements using a reduce
