| Considerando a conveniencia de indicar sucedaneos de mais facil aquisicao e tambem de custo mais baixo do que AIB, foi realizado um ensaio no qual foi testada a hipotese de que 2,4-D estimularia a formacao de raizes laterais e deixaria de ser letal se fosse inibida a producao de etileno no tecido da planta, em resposta a essa auxina, pela adicao deThiabendazol. Com tres semanas apos o plantio, nos dois tratamentos de 2,4-D sem Thiabendazol, houve morte total das plantas, nao tendo havido diferenca entre taxas de pegamento das mudas tratadas com 2,4-D + Thiabendazol e dos outros tratamentos. Caso seja confirmada a ausencia de risco de danos a seringueira com o emprego de 2,4-D associado ao Thiabendazol na inducao de raizes laterais, alem de pronta... |

| In crustacean, immunoreactive peptides were detected with salmon-calcitonin antibodies by immunocytochemistry in its eyestalks and by radioimmunoassay in the haemolymph and the digestive tract. Two different molecules were purified: the first with their molecular weight comprised between 3-5 kDa, the second having a molecular weight of 22 kDa which could correspond to a precursor of the first one. Their characterization is on progress. |

| The <i>Artemia</i> strain from Great Salt Lake (GSL 375) was used. Total body extracts and hemolymph of <i>Artemia</i> were purified by solvent partition and column chromatography. Moulting-hormone concentrations were then determined by a specific radioimmunoassay (RIA). Results are expressed in ng ecdysteroid activity/g fresh weight (or per ml). Initially, the RIA data on extracts of adults were highly variable. The use of a more accurate sampling technique based on the reproductive cycle of the females allowed to determine a hormone activity pattern.In females, moulting cycles alternate with vitellogenic cycles. The lowest values of ecdysone (3-6 ng ecdysone equivalents/g fresh body weight or ml hemolymph) occur during... |

| Centropomidae and Serranidae, sometimes collectively misnamed "sea basses", are suitable for aquaculture in pens, ponds, and raceways around the tropical and subtropical latitudes of the world. Western Atlantic Ocean species were recently considered for farming. South Florida, Mexico, Central and South America and the Antilles areas of the Caribbean Basin have extensive areas suitable for farming groupers and snook. Principal species of interest are the common snook (Centropomus undecimalis ), the fat snook (C. parallelus ), the Nassau grouper (Epinephelus striatus ), Black seabass (Centropristis striatus ), Gag (Mycteroperca microlepis ), and jewfish (E. itajara ). |

| This is an overview of the hormones which may be involved in food intake control in fish, and some hypothetical pathways of their action are given based on mammalian knowledge. Most of the observed effects of these hormones may result from four types of mechanisms, each hormone acting by one or several as follows: (1) hormones could have a direct effect on central nervous system centres, associated with food intake behaviour or via vagal afferent neurons; (2) an indirect effect may occur via the gut which slows gastrointestinal transit, thus resulting in stomach distention which activates vagal afferent neurons; (3) they could have an indirect effect, acting directly on intermediary metabolism via glucose, flee fatty acids or amino acids mobilization or... |

| Gap junctions are intercellular channels which connect adjacent cells and allow direct exchange of molecules of low molecular weight between them. Such a communication has been described as fundamental in many systems due to its importance in coordination, proliferation and differentiation. Recently, it has been shown that gap junctional intercellular communication (GJIC) can be modulated by several extracellular soluble factors such as classical hormones, neurotransmitters, interleukins, growth factors and some paracrine substances. Herein, we discuss some aspects of the general modulation of GJIC by extracellular messenger molecules and more particularly the regulation of such communication in the thymus gland. Additionally, we discuss recent data... |

| The aim of this work was to investigate the influence of diet energy level on performance and hormonal profiles of broilers during post restriction period. It was a split-plot experiment, and the main treatments were in a 2x2 factorial scheme. Birds were fed restricted to 30% of the ad libitum intake, from 7 to 14 days of age. After the restriction period, birds were fed ad libitum with diets containing low (2,900 kcal ME/kg) or high (3,200 kcal ME/kg) energy until 49 days of age. Broilers fed with high energy ration showed lower feed intake and better feed conversion and decreased carcass protein; however, abdominal fat pad, and total carcass fat were not affected by ration energy levels or feeding program. Neither diet energy level nor feed restriction... |

| A choice experiment is used to evaluate how consumers in London, Frankfurt, and Paris value beef steaks with attributes such as: "hormone-free," "GM-free," farm-specific source verification, and domestic origin. The effect of various consumer characteristics on steak selection is also evaluated. Results suggest that European consumers are significantly heterogeneous in their preferences for beef steak attributes. French and German consumers have a higher willingness to pay to avoid genetically modified feed use than British consumers, while German and British consumers would pay more for growth hormone-free beef. French and German consumers are willing to pay for farm-specific source verification. |

| The present research had the purpose to analyze morphologically the sites of endometrial implants on the external area of the musculature of the anterior abdominal wall of female rats, treated with dexamethasone. For so, these 15 albino female rats were used (Rattus norvegicus albinus), of the lineage Wistar with 90 days of age, that were submitted to the induction of the endometriosis, and divided in the following groups: Group I induced female rats to endometriosis and evaluated after 21 days (control); Group II induced female rats to endometriosis and after 21 days, treated with dexamethasone for 10 days; Group III - induced female rats to endometriosis, and after 21 days, treated with dexamethasone for 15 days. The dexamethasone was administered in... |

| The skeleton has several important functions, such as structural functions that provide mobility, support, and protection for the body. It also has an important function as a reservoir for calcium and phosphorus. The aim of this article is to show the principal hormones that are involved with the bone healing process. In this article, it will be pointed the mineral homeostatic mechanisms in the skeleton, controlled by the calcium-regulating hormones: parathyroid hormone (PTH) that maintains the normal extracellular calcium levels by enhancing osteoclastic bone resorption and liberating calcium from the adult skeleton; estrogen, considering that both osteoblasts and osteoclasts express estrogen receptors, it is reasonable to assume that the effects of... |

| Therapeutic doses of 131I administered to thyrotoxic patients may cause thyroid failure. The present study used a rat model to determine thyroid function after the administration of different doses of 131I (64-277 µCi). Thirty male Fisher rats in the experimental group and 30 in the control group (untreated) were followed for 6 months. The animals were 4 months old at the beginning of the experiment and were sacrificed at an age of 9 months. Hormone concentration was determined before 131I administration (4-month-old animals) and three times following 131I administration, when the animals were 7, 8, and 9 months old. The thyroid glands were removed and weighed, their volume was determined and histopathological examination was performed at the end of the... |
