1. Effects of Yucca schidigera on gas mitigation in livestock production: A review
ABSTRACT Yucca schidigera extract (YSE) has received much interest in the application of manure deodorization and hazardous gas mitigation in livestock rearing conditions. The main objective of this review article was to summarize the current knowledge regarding YSE towards its gas mitigation from livestock excrement. Saponins have been considered to be vita

2. Biologia reprodutiva de rainhas e machos de Tetragonisca angustula (Hymenoptera: Meliponini) / Reproductive biology of the queens and males of Tetragonisca angustula (Hymenoptera: Meliponini)
The stingless bees (Hymenoptera: Meliponini)present a haplodiploid sex determination system with complementary sex determination in a single locus. Such a system is a large genetic load for the group and thus the genetic diversity of male\ s aggregations near the nests is essential to minimize the chances of inbreeding. The interactions among the stingless b

4. Seleção hospedeira, controle de qualidade in vivo e criação in vitro de três espécies de tricogramatídeos neotropicais / Host selection, in vivo quality control and in vitro rearing of three neotropical trichogrammatid species
Trichogramma atopovirilia Oatman &Platner, 1983, Trichogrammatoidea annulata De Santis, 1972 and Trichogramma bruni Nagaraja, 1983 are species that occurs naturally in Brazil and just like other species of Neotropical trichogrammatid, they have potential for utilization in biological control programs. Therefore, for this strategy to be implemented, it is nec

5. Isolamento, cultivo e identificação de bactérias com potencial uso probiótico no cultivo de organismos aquáticos: Estudo de caso com bactérias do trato gastrointestinal do linguado Paralichthys orbignyanus (Valenciennes, 1839).
Probiotic organisms are those capable to improve the health of their hosts, by assisting in the food digestion and nutrient assimilation, stimulating their immunological system or by controlling the development of pathogens. However, the use of commercial probiotics poses a serious hazard to the health of farmed animals and to the environment that must be co

6. RECRIA DE BEZERRAS DE CORTE EM ALTERNATIVAS DE USO DA PASTAGEM DE AZEVÉM (Lolium multiflorum Lam.) / REARING OF BEEF HEIFERS IN ALTERNATIVES OF UTILIZATION OF ITALIAN RYEGRASS (LOLIUM MULTIFLORUM LAM.) PASTURE
The performance of beef heifers from eight until twelve months, grazing exclusively Italian ryegrass (Loluim multiflorum Lam.) pasture, ryegrass plus red clover (Trifolium pratense LE 116) and ryegrass plus 1% LW supplement, was evaluated. The grazing period was within July, 27th until October, 14th and a continuous variable stocking was used. A commercial r

7. Toxicidade em camundongos devido à exposição prolongada a uma floração de cianobactérias contendo microcistinas: avaliações comportamental, hematológica, bioquímica e anatomopatológica / Toxicity in mice due to prolonged exposure to a cyanobacterial bloom containing microcystins: behavioral, hematological, biochemical and anatomopathological evaluations
Cyanobacteria (blue-green algae) are prokaryotic and photosynthetic organisms found in practically every type of liquid habitat and that can form great superficial masses of intense green color called blooms. The development of algal blooms on water surface occurs with a higher incidence and is recognised as being a potential health hazard due to the toxic n

8. Evaluation of the central effects of yangambin isolated from Ocotea duckei Vattimo: Behavioral and neurochemical study in mice motor cortex and striatum / Avaliação dos efeitos centrais da iangambina isolada de Ocotea duckei Vattimo: Estudo comportamental e neuroquímico em córtex motor e corpo estriado de camundongo
The effects of the acute administration of yangambin (25, 50 and 75 mg/kg intraperitoneal and oral), were studied in some animals behavioral models (open field, rotarod, forced swimming test, barbiturate-induced sleeping time, hole board, elevated plus maze, pentilenotetrazole-induced convulsion). Binding in vitro with differents concentrations of yangambin

9. Characterization of Wolbachia Host Cell Range via the In Vitro Establishment of Infections†
Maternally transmitted bacteria of the genus Wolbachia are obligate, intracellular symbionts that are frequently found in insects and cause a diverse array of reproductive manipulations, including cytoplasmic incompatibility, male killing, parthenogenesis, and feminization. Despite the existence of a broad range of scientific interest, many aspects of Wolbac

10. Contribution of anaerobic protozoa and methanogens to hindgut metabolic activities of the American cockroach, Periplaneta americana.
The ciliate Nyctotherus ovalis occurs in high numbers in the hindgut of the American cockroach (Periplaneta americana) and harbors methanogenic bacteria as endosymbionts. The contribution of these hindgut microorganisms to metabolic and developmental processes of P. americana was studied by comparing cultures of cockroaches in which the composition of the hi
