2. NMR-Based Metabolomic Screening for Metabolites Associated with Resistance to Meloidogyne javanica in Annona muricata Roots
The resistance of Annona muricata roots to the nematode Meloidogyne javanica was investigated by nuclear magnetic resonance (NMR)-based metabolomics in combination with principal component analysis (PCA). Metabolic changes in roots exposed and not exposed to the nematode were evaluated and compared. In addition, the presence of nematicidal compounds in the r

4. NMR-based metabolomics to select a surgical method for treating papillary thyroid carcinoma
OBJECTIVE: This study aims to investigate differences in the metabolomic profiles of patients who received different surgeries for papillary thyroid carcinoma (PTC). METHODS: Two surgical methods, i.e., unilateral and total thyroidectomy, were employed according to different disease conditions. Sera from patients who were treated with levothyroxine sodium

5. Effect of different vitamin D sources and calcium levels in the diet of layers in the second laying cycle
This study evaluated the effects of different sources of vitamin D and calcium levels on performance, egg quality and bone strength of hens in the second production cycle. A total of 384 Hy-Line W36 birds with 80 weeks of age were used, alloted into 3 x 4 factorial design (sources of vitamin D: cholecalciferol; 25(OH)D3 and 1.25(OH)2D3 x calcium levels: 2.85

6. Azadirachtin biosynthesis induction in Azadirachta indica A. Juss cotyledonary calli with elicitor agents
The use of cell and plant tissues culture techniques to produce economically important active metabolites has been growing. Among these substances, azadirachtin (AZA), produced by the neem tree (Azadirachta indica), has received considerable attention due to its bioinsecticide action. The main goal of this work was to analyze the AZA levels in neem cotyledon

7. Optimizing a culture medium for biomass and phenolic compounds production using Ganoderma lucidum
The present work was aimed at optimizing a culture medium for biomass production and phenolic compounds by using Ganoderma lucidum. The culture was optimized in two stages; a Plackett-Burman design was used in the first one for identifying key components in the medium and a central composite design was used in the second one for optimizing their concentratio

9. Desenvolvimento e aplicação de técnicas miniaturizadas de preparo de amostra na determinação de fármacos no ambiente / Development and application of microextraction sample preparation techniques to determine pharmaceutical drugs in the environment
The occurrence of pharmaceutical drugs in the environment is a worldwide problem caused by the genotoxicity and ecotoxicity activities of those compounds. Water is one of most used natural resource in human activities which explain the presence of emerging contaminants. Those compounds affect not only humans but also aquatic animals that spend the whole life

10. Effect of tanniniferous plants and essential oils on methane emission in ruminants / Efeito de plantas taniníferas e óleos essenciais sobre a emissão de metano em ruminantes
Tannins and essential oils are secondary metabolites that may be used as natural modifiers of rumen fermentation to reduce the ruminants\ methane (CH4) emission. To study the application of tannin-rich plants from Egypt and Brazil, as well as essential oils that are available in international trade, three studies were conducted at Animal Nutrition Laboratory

11. Antibiotics produced by Streptomyces
Streptomyces is a genus of Gram-positive bacteria that grows in various environments, and its shape resembles filamentous fungi. The morphological differentiation of Streptomyces involves the formation of a layer of hyphae that can differentiate into a chain of spores. The most interesting property of Streptomyces is the ability to produce bioactive secondar

12. Elicitores abióticos no estresse oxidativo e na expressão de gene da rota de betacianina em Alternanthera philoxeroides (Mart.) Griseb. / Abiotic elicitors in oxidative stress and in gene expression of the betacyanin route in Alternanthera philoxeroides (Mart.) Griseb
The medicinal Alternanthera (Amaranthaceae) species, such as A. philoxeroides, present a great variety of bioactive compounds, among which are the betacyanins, nitrogen pigments that belong to the betalains class. These compounds are widely used as additives for food and drugs, due to their antioxidant action and lack of toxicity, which have already been pro
