Estudo sobre o acento secundário e a tonicidade dos monossílabos em português arcaico por meio da música e da métrica das Cantigas de Santa Maria

This paper aims to make a study on secondary stress and stress of monosyllabic words in Archaic Portuguese. With regard to secondary stress, our intention is to demonstrate its limits of occurrence. And about monosyllabic words, the aim is to analyse its stress attribution and the possibility of those words assume prominences in the linguistic level demonstrating or not its prosodic independence. The data will be collected by means of a new methodology in the study of the prosody of dead language. This methodology is based on the observation of coincidences and non-coincidences of musical prominences of poetic texts with musical notation, and linguistic prominences.

O acento secundário no português arcaico

This paper aimsto study secondary stressinArchaic Portuguese demonstrating its limits of occurrence and its behavior through the Metrical Theory by Hayes (1995). The data was collected by means of a new methodology in the study of the prosody of ancient periods of the language. This methodology is based on the observation of matching and mismatching of musical and linguistic prominences of poetic texts with musical notation.

HPLC-EICD: An Useful Tool for the Pursuit of Novel Analytical Strategies for the Detection of Antioxidant Secondary Metabolites

Living cells are continuously exposed to a variety of challenges that exert oxidative stress and are directly related with senescence and the onset of various pathological conditions such as coronary heart disease, rheumatoid arthritis and cancer. Nevertheless, living organisms have developed a complex antioxidant network to counteract reactive species that are detrimental to life. With the aim of bio-prospecting plant species from the Brazilian Cerrado and Atlantic Forest, we have established a methodology to detect secondary antioxidant metabolites in crude extracts and fractions obtained from plant species. Combining HPLC with an electrochemical detector allowed us to detect micromolecules that showed antioxidant activities in Chimarrhis turbinata (DC) leaf extracts. Comparison with purified flavonoid standards led us to identify the compounds in their natural matrices giving valuable information on their antioxidant capacity.
