37. Evaluation of Meat and Egg Traits of Beijing-you Chickens Rotationally Grazing on Chicory Pasture in a Chestnut Forest
ABSTRACT Barn and cage-fed chickens have presented several problems, such as high rates of infectious disease and consequent antibiotic abuse, poorer chicken health and welfare, and often poorer meat and egg quality compared with free-range chickens. The poultry agroforestry system is becoming increasingly popular in many poultry farms nowadays. In this stud

38. Follicular helper T cell in immunity and autoimmunity
The traditional concept that effector T helper (Th) responses are mediated by Th1/Th2 cell subtypes has been broadened by the recent demonstration of two new effector T helper cells, the IL-17 producing cells (Th17) and the follicular helper T cells (Tfh). These new subsets have many features in common, such as the ability to produce IL-21 and to express the

39. Inductive plethysmography potential as a surrogate for ventilatory measurements during rest and moderate physical exercise
Background: Portable respiratory inductive plethysmography (RIP) systems have been validated for ventilatory assessment during resting conditions and during incremental treadmill exercise. However, in clinical settings and during field-based exercise, intensity is usually constant and submaximal. A demonstration of the ability of RIP to detect respiratory m

40. Electrified Water: Liquid, Vapor and Aerosol
Many reports associate electrostatic charge in dielectrics with water, either bulk, finely dispersed in aerosol or as atmospheric vapor. Two widespread but currently controversial assumptions relevant to this topic are the prevalence of electroneutrality and the passive role of water in electrical phenomena, dissipating charge due to its significant electric

43. QUÍMICA VERDADEIRAMENTE VERDE – PROPRIEDADES QUÍMICAS DO CLORO E SUA ILUSTRAÇÃO POR EXPERIMENTOS EM ESCALA MINIATURIZADA
Chlorine, one of the most frequent elements on earth and most important key chemicals, is indispensable in the syllabi of school and university courses in Inorganic Chemistry. However, its toxicity and high volatility preclude experimental demonstration of its properties in secondary and high schools and most university labs. This paper summarises the indust

44. Alpha adrenergic receptors in renal pelvis and calyces: can rat models be used?
We aimed, in this study, to determine the distribution of α-1 AR subtypes in rat and human pelvis and calyces, and to evaluate, by comparing these two species, the possibility of rats to be used as models for humans. Twenty patients with renal carcinoma were included into the study. The patients underwent radical nephrectomy for renal cell carcinoma (RCC).

45. Randomized double-blind clinical trial of a new human epoetin versus a commercially available formula for anemia control in patients on hemodialysis
OBJECTIVES: Anemia is a common complication among chronic kidney disease patients on hemodialysis, occurring mostly due to erythropoietin deficiency. This randomized noninferiority trial sought to compare the efficacy and safety of a new epoetin formulation developed by Bio-Manguinhos, a biologics manufacturer affiliated with the Brazilian government, with

46. Construção de eletrodo de grafite retirado de pilha comum: aplicações didáticas
This paper presents a proposal for using recycled graphite electrodes obtained from exhausted commercial 1.5 V batteries and its application in electroanalysis. The electrode could be prepared by the students and applied in the simple didactic experiments suggested, such as determination of active electrode area, cyclic voltammetry and useful potential range

48. Traditional use and safety of herbal medicines
In the European Union, traditional herbal medicines that are regarded as "acceptably safe, albeit not having a recognized level of efficacy" fit into a special category of drugs ("traditional herbal medicine products") for which requirements of non-clinical and clinical studies are less rigorous. A regulation proposal published by the Brazilian National Heal
