“…(b) Adolescents exhibited greater activation for interference relative to neutral conditions in the regions of left posterior-medial frontal cortex, left and right inferior frontal gyrus, left and right inferior parietal lobules, right insula, right superior frontal gyrus, and left middle frontal gyrus, displayed at p(FWE) < .001 (see Table 1). Reprinted from Kim-Spoon et al, 2016. to activate the anterior cingulate cortex, and the parietal, premotor, and dorsolateral prefrontal cortices. In the MSIT, participants are presented with sequences of three digits, two of which are identical.…”

We examined whether cognitive control moderates the effects of emotion on adolescent internalizing and externalizing symptomatology in a longitudinal study of 138 adolescents. Self-reported positive affect (PA) and negative affect and behavioral and neural indicators of cognitive control, indexed by performance and prefrontal hemodynamic response during a cognitive interference task, were collected at Time 1. Self-reported internalizing and externalizing symptomatology were collected at Time 1 and Time 2 (1 year later). Results indicated that higher PA predicted decreases in externalizing symptomatology, but only for adolescents with poor neural cognitive control. No moderation effects were found for behavioral cognitive control. Findings imply the beneficial effects of PA on the development of externalizing problems among adolescents with poor prefrontal functioning.

Bertholletia excelsa Bonpl. (Lecythidaceae) is a South American tree worldwide known for providing the Brazil nuts. In the Amazon Region, B. excelsa is found in monocultures, integrating agroforestries and providing raw materials for food and timber industries. Through the application of an integrative analysis based on high-performance liquid chromatography coupled with diode array detector and tandem mass spectrometry (HPLC-DAD-MS/MS) and nuclear magnetic resonance (NMR) techniques, the present study showed that B. excelsa bark biomass residues contain large quantities of ellagic acid (EA) and its derivatives. Qualitatively, five compounds were characterized for the first time in this species. Quantitations were carried out to determine the total amount of these compounds in outer and inner bark tissues. A total of 4.96 and 44.09 g of EA derivatives per kg of dry residues was determined for the outer and inner barks, respectively. Among the EA derivatives, eschweilenol C, ellagic acid and valoneic acid dilactone were the main compounds. These results pointed B. excelsa barks as a valuable biomass residue with potential to be source of health-promoting compounds. Therefore, a potential raw material as source of valuable bioactive phenolic compounds is described herein.

“…The use of plants for disease treatment purposes in Brazil -a country that hosts a wide variety of native plants and more than 817 thousand indigenous individuals (IBGE, 2010; COAN; MATIAS, 2013) -dates back to the pre-colonial period, when forests were the main source of medicines to Amerindians, as well as to the post-colonial period, when herbal medicines were essential to the treatment of several epidemic diseases. Nowadays, plants remain important therapeutic elements of health and illness profiles (SILVA;FREIRE, 2013;BRANDELLI et al, 2013;FRAUSIN et al, 2015).…”

Antiparasitic Plants Used by the Kantaruré-Batida Indigenous Community (Ne-Brazil): Ethnobotany and Local Knowledge-Erosion Risks

et al. 2018

Indigenous people have an intrinsic relationship with the flora used in healing systems. However, data about plants used to treat intestinal parasitosis, which are one of the main morbidity and mortality causes among indigenous peoples, remain scarce. Thus, the aim of the current study is to survey antiparasitic plants used by the Kantaruré-Batida community and to investigate whether their ethno-medico-botanical knowledge is spread. Therefore, it adopted interviews and free lists. Thirty-one (31) indigenous individuals were interviewed and they mentioned 21 plant species. Most respondents (91%) acquired the traditional knowledge through hereditary transmission and spread it (77%) in the same way. Only 35% of the respondents adopt medicinal plants as the first cure resource, besides associating the decrease of such use to their proximity to health care services. Thus, it is worth taking actions to help preserving the local knowledge and biodiversity in order to avoid the loss of indigenous therapeutic treatments.
