Atributos químicos do solo, reservas orgânicas e sistema radicular de pastos degradados associada à introdução de leguminosa

The aim was to study the recovery of degraded pasture with the introduction of Stylosanthes macrocephala e capitata cv. Campo Grande on Brachiaria decumbens cv. Basilisk evaluating the levels N-total in roots, biomass, area, and length, diameter and root levels of macro and micronutrients in the soil. The experiment was conducted in the municipality of Andradina, Sao Paulo State, Brazil. The experimental design was a randomized block design in a split-plot (with and without phosphorus), with four replicates, forming the following treatments: control Brachiaria decumbens (CB), partial desiccation with 1.5 L ha(-1) of glyphosate (DP), total desiccation with 3.0 L ha(-1) of glyphosate (TD); tillage (T), soil scarification (S); harrowing rome (H) and plowing + disking (PD). Treatments H and PD were sown by broadcasting and the other in the form of direct seeding. Recovery strategies of grazing signal grass showed significant differences between treatments only for the content of N-total, there were no differences in geometric characteristics of roots and root biomass. The contents of macro and micronutrients in the soil showed no significant differences between the strategies of recovery. Fertilization had a significant effect for P. The introduction of estilosantes Campo Grande accompanied by techniques such as drying and plowing + disking contributed to increases in the N-total levels in the root system. Forms of introduction of legumes did not change the soil chemical properties.

Delayed tooth replantation: MTA as root canal filling

MTA has been investigated as a root-end filling material. Its mechanism of action has some similarities to that of Ca(OH())2. The purpose of this study was to evaluate the repair process taking place in the delayed replantation of monkey teeth using calcium hydroxide and MTA as root canal filling materials. Five monkeys had their lateral incisors extracted and bench-dried for 60 minutes. After root canal preparation, the teeth were assigned to two groups according to root canal filling material: I, calcium hydroxide; and II, MTA. The same treatment sequence was followed for both groups: coronal seal, periodontal ligament removal, immersion of the tooth in 2% acidulated-phosphate sodium fluoride, irrigation of the socket with saline and replantation. Both groups exhibited replacement resorption, areas of ankylosis and absence of inflammatory root resorption. Statistically similar results (p > 0.05) were observed for both groups regarding replacement root resorption, but the groups differed significantly (p < 0.05) regarding the occurrence of ankylosis. MTA may be a viable clinical option for filling teeth submitted to delayed replantation, and is an acceptable option for treating replanted permanent teeth in order to prevent tooth resorption, particularly when dressing changes are not possible.

Avaliações de estratégias de recuperação de pastagens com a introdução de leguminosas

Com o objetivo de avaliar a incidência populacional de plantas daninhas em diferentes manejos de implantação de Stylosanthes guianensis cv. Campo Grande em pastagem de Brachiaria decumbens. Realizou-se um experimento na AgênciaPaulista de Tecnologia dos AgronegóciosExtremo Oeste no município de Andradina/SP emfevereiro de 2011. Utilizou-se o delineamento experimental em blocos ao acaso em esquema de parcelas subdivididas, com quatro repetições e compostos por sete tratamentos (parcelas principais) e duas testemunhas: T1=Plantio direto com dessecação ½ dose de glifosato; T2=Plantio direto sem dessecação; T3=Plantio direto com escarificação do solo; T4=GradagemRome + Plantio direto; T5=Sistema convencional; T6=Brachiaria decumbens e T7= Estilosantes Campo Grande (dessecação com glifosato). Foi avaliado a massa seca de espécies infestantes em diferentes manejos de implantação de Estilosantes Campo Grande, aos 15 dias após semeadura. Os resultados foram submetidos à ANOVA para comparação múltipla de médias, a 5% de significância pelo teste de Tukey. Os T2, T3 e T6 apresentaram uma maior massa seca de espécies infestantes, foram diferentes estatisticamente dos demais (P<0,05), porém não houve diferença significativa entre eles (P>0,05). A massa seca das monocotiledôneas é praticamente toda de Brachiaria decumbens e das dicotiledôneas foi insignificante.

Treatment of traumatic dental intrusion by surgical repositioning: clinical case report

The prevalence of dental trauma and its consequences are challenging. This article presents a clinical case of a 9-year-old female who was in a bicycling accident and had a dental intrusion of the left maxillary lateral incisor with extensive dislocation. In the emergency department, surgical repositioning of the intruded tooth and a splinting with steel wire and composite resin was performed and the soft-tissue lesions were sutured. Two weeks after the first visit, pulp necrosis was found and endodontic treatment of the intruded tooth was started with a calcium hydroxide dressing. Despite the traumatic nature of the dental injury, the result of treatment was favorable. After 3 years of follow-up, repair of the resorptions and no signs of ankylosis of the teeth involved were evident. Considering the patient's age and the extent of intrusion, it was concluded that surgical repositioning associated with adequate endodontic therapy was an effective alternative treatment for this case.

Scrupocellaria (Bryozoa: Cheilostomata) from the Queensland coast, with the description of three new species

Among the Scrupocellaria species previously reported from Queensland, three are here redescribed - S. cervicornis, S. curvata and S. diadema; two other species, S. frondis and S. sinuosa, are recorded from the area for the first time; three new species, S. hamata n. sp., S. prolata n. sp. and S. peltata n. sp., are also described, and the remainder are discussed. The need for the re-examination of specimens assigned to this genus is highlighted. The geographic range of some Scrupocellaria species is far more limited than once thought.
