13. Screening and characterization of endophytic Bacillus and Paenibacillus strains from medicinal plant Lonicera japonica for use as potential plant growth promoters
Abstract A total of 48 endophytic bacteria were isolated from surface-sterilized tissues of the medicinal plant Lonicera japonica, which is grown in eastern China; six strains were selected for further study based on their potential ability to promote plant growth in vitro (siderophore and indoleacetic acid production). The bacteria were characterized by phy

14. Cultivable endophytic bacteria from leaf bases of Agave tequilana and their role as plant growth promoters
Agave tequilana Weber var. 'Azul' is grown for the production of tequila, inulin and syrup. Diverse bacteria inhabit plant tissues and play a crucial role for plant health and growth. In this study culturable endophytic bacteria were extracted from leaf bases of 100 healthy Agave tequilana plants. In plant tissue bacteria occurred at mean population densitie

15. DNA methylation regulates expression of VEGF-C, and S-adenosylmethionine is effective for VEGF-C methylation and for inhibiting cancer growth
DNA hypomethylation may activate oncogene transcription, thus promoting carcinogenesis and tumor development. S-adenosylmethionine (SAM) is a methyl donor in numerous methylation reactions and acts as an inhibitor of intracellular demethylase activity, which results in hypermethylation of DNA. The main objectives of this study were to determine whether DNA h

16. Phytogenic additives and glutamine plus glutamic acid in broiler diets
The objective of this study was to evaluate the effect of the dietary supplementation of phytogenic additives (PAs) and glutamine plus glutamic acid (Gln/Glu), associated or not, in replacement of antibiotic growth promoters and anticoccidials (AGP/AC) on the performance and carcass yield of broilers. Five hundred male Cobb broilers were housed in an experim

17. 2D map of proteins from human renal stone matrix and evaluation of their effect on oxalate induced renal tubular epithelial cell injury
PurposeProteins constitute a major portion of the organic matrix of human calcium oxalate (CaOx) renal stones and the matrix is considered to be important in stone formation and growth. The present study evaluates the effect of these proteins on oxalate injured renal epithelial cells accompanied by a 2D map of these proteins.Materials and MethodsProteins wer

18. UtilizaÃÃo de promotores de crescimento em raÃÃo para frangos de corte / Use of growth promoters in feed for broiler
Two experiments were carried out to evaluate the effects of using distinct growth promoter over the energetic metabolism and performance of poultry farming. Two experimental diets (ND â normal diet according to nutritional requirements and RD â reduced diet, with 5% less of nutrients), supplemented or not with antibiotics and prebiotics from 1 to 10, 11 to

19. Use of probiotics to replace antibiotics for broilers
This study was carried out to evaluate the effect of supplementation of probiotics (Lactobacillus acidophilus, Enterococcus faecium and Bifidubacterium bifidum) and antibiotics (flavomicina and staquinol) on diets for broilers from 1 to 42 days of age, reared in clean (new litter) and challenged (reused litter) environments. A total of 768 one-day-old male b

20. Microcystin-XR degradation by bacteria isolated from public water supply system / Degradação da microcistina-XR por bactérias isoladas de sistema de abastecimento público de água
Microcystins are potent hepatotoxins and tumor promoters found in freshwaters that cause public health risks and thus represent a serious problem for water treatment plants. The cyanobacterium genus Microcystis is the most known toxin-producer and the most common bloom-forming in water reservoirs used for public supply. However, some bacteria are able to use

21. REDAÇÕES DO ENSINO MÉDIO: UMA LEITURA POR VIAS FUNCIONAIS DE ENUNCIAÇÃO / SECONDARY EDUCATION ESSAYS: A FUNCTIONAL READING OF ENUNCIATION
The aim of this study is to argue that the essays of students from secondary education can deserve a reading different from the one customarily made, supported by normative grammar. It includes teachers¿ understanding that, to start with, the student¿s text is a timely and possible expression of an individual who, through language (Bakhtin, 1979), is in an

22. Caracterização de cepas de Escherichia coli contendo diferentes alelos rpoS. / Characterization of Escherichia coli strains carrying different rpos alleles.
Escherichia coli can be found in many different habitats and has to be prepared to survive and grow under unfavorable conditions. Bacteria adaptation to different growth conditions requires an efficient control of gene expression. One of the primary forms of gene expression control is the competition between different sigma factors for the binding to the cor

23. Medium composition influence on Biotin and Riboflavin production by newly isolated Candida sp
Complex B vitamins as Biotin and Riboflavin are required by living organisms, not only for growth but also for metabolite production, and the feed market classifies them as growth promoters. Since Brazil will soon be one of the world's biggest animal protein producers, feed production is a large consumer of vitamins and micronutrients. The industry requires

24. Avaliação de antimicrobianos como promotores de crescimento via mistura mineral para bovinos de corte em pastejo / Antimicrobial growth promoters in mineral mixtures for grazing beef cattle
Antimicrobials which modifies rumen fermentation can improve economical efficiency of beef cattle grazing systems and reduce its possible impacts on the environment. It was conducted a series of experiments with the objective of evaluating free-choice mineral mixtures as an antimicrobial delivery system for grazing animals. On experiment 1, at Piracicaba-SP,
