Effect of essential oil from Citrus aurantium in maternal reproductive outcome and fetal anomaly frequency in rats

Citrus aurantium L., commonly known as bitter orange, is widely used in folk medicine, but there is little data in the literature about the s on pregnancy. The aim of the present study was to evaluate the influence of essential oil obtained from fruits of Citrus aurantium on the maternal reproductive outcome and fetal anomaly incidence in rats. Pregnant Wistar rats were randomized into four groups (n minimum = 12 animals/group): G1 = control, G2 to G4 = treated with essential oil from C. aurantium at dose 125, 250 and 500 mg/kg, respectively. Rats were orally treated, by gavage, with plant essential oil or vehicle during pre-implantation and organogenic period (gestational day 0-14). On gestational day 20 the rats were anaesthetized and the gravid uterus was weighed with its contents and the fetuses were analyzed. Results showed that the treated group with 500 mg/kg presented decreased placental weights and placental index, although the treatment with bitter orange essential oil did not show any alteration in maternal reproductive performance, toxicological , changes in ossification sites, and malformation index. In conclusion, the treatment of Citrus aurantium essential oil was not teratogenic and did not alter the maternal reproductive outcome.

Pinos transcorticais e gesso associados à aplicação local de plasma rico em plaquetas no tratamento de fratura do III metatarsiano em potro

In horses less than one year of age fractures of the third metacarpal bone (McIII) or metatarsal bone III (MtIII) are mainly attributed to trauma. Open reduction and internal fixation are the most common treatment method. A Quarter Horse filly with three months of age, which weighed 150kg presented a diaphyseal multifragmentar wedge fracture of right MtIII which was treated with transcortical pins and cast, associated with intralesional application of platelet rich plasma (PRP). After two years of surgery, the animal initiated a training program for racing, and six months later, the patient ran its first official match. The choice of therapeutic methods for treating fractures in horses should be one that provides an earlier repair and minor possibility of complications. Thus, the therapy association which was adopted was considered favorable, since allowed full reestablishment of locomotion of the patient and made possible its return to race.

Caracterização física e química dos frutos nos diferentes quadrantes da planta e germinação de sementes do portaenxerto cítrico tangerineira ‘sunki’

The tangerine 'Sunki' are highly relevant for the Brazilian citrus industry by presenting important traits for genetic improvement and to be considered a great portaenxento. In this context, the objective of the present work to study the characterization of the fruits of citrus rootstock 'Sunki', depending on the position on the plan and also the germination of their seeds. The physical characteristics evaluated were fruit weight, longitudinal and equatorial diameters of the fruit longitudinal diameter / equatorial diameter, number of buds per fruit, weight of buds and bark and number of viable seeds per fruit. As for the chemical characterization was evaluated titratable, acidity, soluble solid, "Ratio", pH and vitamin C. For the evaluation of these variables, the fruits were obtained from the northeast, southwest, northwest and southeast quadrants. Regarding the evaluation of seed germination, different doses of gibberellic acid and Stimulate were used. The seeds extracted from ripe fruit, washed, dried in the shade and stored in BOD. Immediately after, they were treated for 24 hours with plant growth regulators. After soaking, the seeds were placed in a germinator in germitest paper. After initiation of the germination process, the evaluations were performed daily until the thirty- fourth day. Fruits of 'Sunki'mandarin with uneven as the fruit position within the canopy, the use of gibberellic acid and growth promoter is promising for commercial use on seed germination of this rootstock.

Adubação nitrogenada e potássica em goiabeiras ‘paluma’: II. efeito no estado nutricional das plantas

The proper mineral fertilization of guava orchards under intensive management, is a major factor in productivity and monitoring the nutritional status of the plants contributes to the efficiency of this agronomic practice. The aim of this study was to investigate different doses of nitrogen and potassium in the nutritional status of guava 'Paluma'. The experiment was conducted at Vista Alegre do Alto, Sao Paulo, in a 7 year old irrigated orchard, managed with fruiting pruning during four consecutive growing seasons. The soil is a dystrophic Ultisol. The experimental design was randomized blocks, in factorial, with four nitrogen doses (0, 0.5, 1 and 2 kg of N plant(-1)) and four of potassium (0, 0.55, 1.1 and 2.2 kg of K2O plant(-1)), with three replications. Nitrogen fertilization promoted increased levels of leaf N and Mn and the decrease in the levels of P and B; effects observed from the second to the fourth production cycle. Nitrogen fertilization increased the Ca and Mg levels, respectively, in the second and third cycle. Except for the first production cycle, K and Mn foliar concentrations increased with increasing potassium fertilization, whereas the levels of Mg, in the second and the fourth cycle, decreased as a function of fertilization.

Resposta funcional da joaninha Cryptolaemus predando Cochonilha branca em diferentes temperaturas e substratos vegetais

This work was carried out to evaluate the functional response of Cryptolaemus montrouzieri Mulsant, 1850 (Coleoptera: Coccinellidae) fed with Planococcus citri Risso, 1813 (Hemiptera: Pseudococcidae) reared on a pumpkin hybrid (Cucurbita maxima x Cucurbita moscata) (Cucurbitaceae), seedlings of Rangpur lime (Citrus limonia) Rutaceae) and potato (Solanum tuberosum) (Solanaceae) at two temperatures. The predation rate of C. montrouzieri was measured using Petri dishes of 15 cm diameter with 1, 2, 4, 8, 16 and 24 adults of P. Citri. One third instar larva, one fourfh instar and one newly emerged adult (without differentiation of sex) of C. montrouzieri were added to each plate. The study was conducted in climatic chambers at temperatures of 25 and 30 degrees C and photophase of 12 hours. The predation rate was evaluated after 24 hours of prey exposition to the predator, by counting the number of preys trapped in the different treatments and control. The statistical design was completely randomized with four treatments x 6 subplots with 7 repetitions, the two temperatures. The values obtained were subjected to analysis of variance, to relate the number of scales preyed by larvae and adults of C. montrouzieri set up in different substrates. The amount of prey consumed by larvae and adults of the predator increased with increasing the prey density until it reaches a plateau, characterizing functional response type II. In general, the number of scales preyed by larvae and adults of C. montrouzieri was higher on potato and under temperature of 30 degrees C.

A formação do professor-pesquisador no curso de licenciatura em educação física

A formação inicial do professor-pesquisador tem como pressuposto formar um docente mais autônomo e observador de sua prática pedagógica, relacionando ensino com investigação. A formação de um novo professor requer sua iniciação em valores, representações, saberes e fazeres (SARTI, 2009) e o professor-pesquisador busca investigar sua prática e resolver seus desafios, sem distanciar-se da teoria. Para abranger esta formação, o presente estudo propõe como objetivo geral compreender como os estudantes do curso de licenciatura em Educação Física da UNESP de Rio Claro interpretam a sua prática profissional em situação de estágio supervisionado na perspectiva do professor-pesquisador. Como objetivos específicos buscou-se: (1)Observar se os estagiários são estimulados a refletir sobre sua ação pedagógica; (2)Verificar se a disciplina de Prática de Ensino se aproxima de uma proposta de formação do professor que investiga a sua prática; (3)Identificar os elementos constitutivos de uma ação reflexiva e; (4)Averiguar se os estudantes de educação física se reconhecem como professores que investigam a sua prática.
