1. Feeding effects of cottonseed and its co-products on the meat proteome from ram lambs
ABSTRACT: Gossypol easily pairs with lysine side chains and enzymes involved in the cellular growth process. The effect of gossypol (a compound present in cotton co-products) in ruminant metabolism and meat quality is not yet clear. This study was undertaken in order to evaluate the effects of cotton co-products in lamb muscle proteome. Twenty-four Santa In�

3. Chemical constituents from ethanol extract of Polyalthia rumphii branches and their cytotoxicity evaluation
ABSTRACT Twelve known compounds, including eight alkaloids, three lignans and one gossypol derivative, were isolated from the branches of Polyalthia rumphii (Blume ex Hensch.) Merr., Annonaceae. The chemical structures were determined by spectroscopic methods and comparison with literature data. All the isolates were evaluated the cytotoxicity against three

4. An Environmental Friendly Flow-Injection Procedure for On Line Extraction and Spectrophotometric Determination of Gossypol in Cottonseed Meal
A fast, simple and inexpensive procedure is described for the determination of gossypol in cottonseed meal. The procedure is based on a flow injection analysis system and a complexation reaction with spectrophotometric detection at 620 nm. A fluidized bed column was used to implement the on line that was coupled to the extraction flow system in order to anal

5. Impact of feeding cottonseed coproducts on reproductive system of male sheep during peripubertal period
ABSTRACT Cottonseed coproducts contain gossypol which can have specific effects upon the male reproductive system. We evaluated the reproductive development of male lambs close to puberty fed on three cotton coproducts. Twenty-four 5-month old male lambs received four diets: 20 % of dry matter intake of whole cottonseed (WCS), high oil cottonseed meal (CSC),

6. GOSSYPOL PROMOTES THE DEGENERATION OF CHICKEN OVARIAN FOLLICLES IN VITRO
ABSTRACT Gossypol, a phenolic compound produced by the pigment glands of cotton, is known to affect male reproduction. In females, exposure to gossypol has been associated with interference with the estrous cycle and embryo development. In laying hens fed cottonseed, gossypol was found to reduce egg production and weight and to cause discoloration of the egg

7. Effect of gossypol on survival and reproduction of the zoophytophagous stinkbug Podisus nigrispinus (Dallas)
Efeito do gossipol na sobrevivência e reprodução do percevejo zoofitófago Podisus nigrispinus (Dallas). O gossipol é um aldeído sesquiterpeno produzido pelo algodoeiro que confere resistência contra a herbivoria. A interação deste sesquiterpeno com predadores zoofitófagos, como Podisus nigrispinus (Dallas) (Hemiptera, Pentatomidae), é inexistente

8. The developmental toxicity of cottonseed extraction on chicken embryo
Cottonseed meal is widely used as one of the protein supplement in poultry diets. Its mechanism of toxic action on chicken embryo is poorly understood. In this study, direct effects and abnormalities of cottonseed on chicken embryo were studied. Oxidative stress, cholinergic stress, mineral analysis and microscopic lesions were analyzed in chicken embryo whi

9. Desempenho e espermatogenese de alevinos de tilapia alimentados com farelo ou farinha de semente de algodao.
Este trabalho avaliou o efeito do farelo e da farinha de semente de algodao no ganho de peso e na atividade testicular de alevinos de tilapia-do-nilo (Oreochromis niloticus). Cento e cinqueta alevinos com peso medio inicial de 1,26 g foram mantidos em aquarios de 45 L, com renovacao continua d'agua, e alimentados por 120 dias com dietas isoproteicas (28% PB)

10. Compatibilidade do predador Podisus nigrispinus (Heteroptera: Pentatomidae) com gossipol / Compatibility of the predator Podisus nigrispinus (Heteroptera: Pentatomidae) with gossypol
Stinkbug as Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) they can, occasionally, they be fed of plants. That behavior is important for the survival of those predators in situations of preys shortage. The addition of plants to the diet has been increasing the acting of P. nigrispinus, for supplying water and, possibly, nutritious to that predator.

12. Compatibility of the predator Brontocoris tabidus (Heteroptera: Pentatomidae) with cotton plants with gossypol glands / Compatibilidade do predador Brontocoris tabidus (Heteroptera: Pentatomidae) com algodoeiro com glândulas de gossipol
O uso de cultivares resistentes em programas de produção do algodoeiro torna importante o conhecimento dos efeitos dessas cultivares sobre a biologia de insetos-praga e nos indivíduos do terceiro nível trófico que atuam, diretamente, como agentes controladores. O objetivo foi avaliar o desenvolvimento, reprodução e parâmetros da tabela de vida do pre
