This paper is the result of an investigation of the flora and traditionalknowledge in the conception of Javaé indigenous people from the Txuirivillage located on Bananal Island, Brazil. The objective is to investigatethe plants used by these indigenous people, their diverse uses and tounderstand how traditional knowledge is passed on to new *** is a qualitative, descriptive and interdisciplinary survey, whose datacollection strategies included the application of semi-structured questionnairesand collection of plants for cataloguing according to AngiospermPhylogeny Group or APG III (2009). We identified 26 plant species, usedfor various purposes such as medicinal use, food, construction, craft andcultural, which were deposited in the Herbarium of the Federal Universityof Tocantins. Roots, stem and leaf are the plant parts most used bythe community. The plants mentioned were most frequently found on thebanks of the Javaés River and in the backyard of the residences. Significanttraditional knowledge of these people about the plants are transmittedto new generations, through visual, orality and experimentation. Ethnobotanicalstudies strengthen research in ecopsychology while allowingresearch into the interactions between human populations and plants.

This study was designed to investigate whether essential fatty acid deficiency early during development could change the content of phospholipids and cholesterol in whole membranes of the kidney and renal function at adult life. For this, female Wistar rats were maintained on a standard diet or on an essential fatty acid deficient diet (EFAD) from the age of 30 days, throughout the pregnancy, at age of 90 days and until the weaning, for evaluation of their offspring. Weanling rats were maintained on a standard diet until the age of 13 weeks. Systolic blood pressure (SBP), glomerular filtration rate (GFR), urinary sodium excretion (UNa+V), positive cells for angiotensin II (Ang II) and cholesterol and phospholipids in whole membranes of the kidney were evaluated. Cholesterol, total phospholipids and the relative content of classes of phospholipids were unaltered in the cortex and medullary kidney. SBP, GFR and UNa+V were also unaltered in the EFAD group. However, the number of positive cells for Ang II in the tubulointerstitial area of the renal cortex was higher in the EFAD group. Therefore, these findings indicated that although cholesterol and phospholipids were unaltered and urinary sodium excretion was unchanged, Ang II expression in the kidney was erroneously programmed and later hindering of renal function was not ruled out.

The Anonnaceae family has 2,500 species and 135 genera, which has about 14 representatives of species in Brazil,including Pseudoxandra cuspidata. The objective of this research was to study the aqueous-acid extract of P. cuspidata, evaluatingits antioxidant, larvicidal, antimicrobial and cytotoxic potential. In the preliminary phytochemical analysis, there were positivity toorganicacids and alkaloids. Inhibitory Activity of EAA was 65% against DPPH. The AAE presented to A. Salina nauplii at LC50%of 600.79 μg/mL for a periodof 24 hours. In relation to larvicidal activity to Aedes aegypti intermediates, AAE presented the LC50%in 24 Hours of 475.91 ppm and 290.73 ppm in 48 Hours. Regarding the antimicrobial action, the EAA presented 50 mg/mL MIC forP. Aeruginosa and MBC at 100 mg/mL, and for S. aureus it presented MIC of 50 mg/mL and did not present MBC. This researchcharacterized the presence of alkaloids and organicacids present in the aqueousacid extract of P. cuspidata. The extract presentedlowtoxicity in relation to the microcrustacean A. salina. It also had a relevant antioxidant potential (65% of Inhibition),larvicidalaction considered effective, antimicrobialaction for both P. Aeruginosa and S. Aureus even did not present bactericidalaction.

High purity semiconductor films commit 50% of crystalline photovoltaic cell cost and current efforts focus on photovoltaic alternative devices, known as wafer equivalents, based on reduction of substrate and active light absorbing layer thickness and use of foreign substrates instead of traditional silicon wafers. In this way, knowing the substrate crystalline fraction, roughness and grain size distribution is relevant for thin film epitaxial growth. This work presents a semi-quantitative crystalline fraction analysis measured by Raman mapping microscopy of pc-Si sheets prepared by Atmospheric Thermal Plasma Spray (ATPS) as initial reference for solar cell substrates. Results showed a structural mixed silicon sheet with different values of crystalline fraction, specific regions of amorphous structure contribution, transition regions and a range of crystallite size. The results suggests the need for better ATPS substrate temperature control for higher and homogeneous crystalline fraction values to attend to requirements of a thin film solar cell substrate.
