Bactérias promotoras de crescimento e adubação nitrogenada no crescimento inicial de cana-de-açúcar proveniente de mudas pré-brotadas

The objective of this work was to evaluate the effects of the inoculation with plant growth-promoting bacteria on the formation of sugarcane pre-sprouted seedlings, originated from individual buds, and to quantify the initial growth of these seedlings in association with nitrogen application, in a low fertility soil. Two experiments were carried out: one in greenhouse conditions, with a time span of 50 days, and the other in vases under field conditions, with a time span of 180 days. In both experiments, a randomized complete block design was used with a factorial arrangement of 2x3, in the first experiment - with or without inoculation, and with three quantities of bud reserve -, and of 2x2x4, in the second one - with or without inoculation, with or without nitrogen, evaluated in four times: at 45, 90, 135, and 180 days. The inoculant had effect on the initial growth of the pre-sprouted seedlings, increasing sprouting speed and dry matter accumulation on roots and shoots, regardless of the bud reserve amount. In the second experiment, the inoculant increased the initial growth of shoots and root system up to 180 days after transplantation, increasing height, tillering, stalk diameter, dry matter production of stalks and straw, and root length, regardless of nitrogen application. The inoculant has a positive physiological effect on plant growth.

Functional neurologic recovery in two dogs diagnosed with severe luxation of the vertebral column

Traumatic injuries to the vertebral column, spinal cord, and cauda equina nerve roots occur frequently in human and veterinary medicine and lead to devastating consequences. Complications include partial or complete loss of motor, sensory, and visceral functions, which are among the main causes of euthanasia in dogs. The present case report describes neurological functional recovery in two dogs that were treated surgically for severe spinal fracture and vertebral luxation. In the first case, a stray, mixed breed puppy was diagnosed with thoracolumbar syndrome and Schiff-Scherrington posture, as well as a T13 caudal epiphyseal fracture with 100% luxation between vertebrae T13 and L1; despite these injuries, the animal did show deep pain sensation in the pelvic limbs. Decompression through hemilaminectomy and spinal stabilization with vertebral body pins and bone cement were performed, and the treatment was supplemented with physiotherapy and acupuncture. In the second case, a mixed breed dog was diagnosed with a vertebral fracture and severe luxation between L6 and L7 after a vehicular trauma, but maintained nociception and perineal reflex. Surgical stabilization of the spine was performed using a modified dorsal segmental fixation technique Both patients showed significant recovery of neurological function. Complete luxation of the spinal canal observed radiographically does not mean a poor prognosis, and in some cases, motor, sensory, and visceral functions all have the potential for recovery. In the first case the determining factor for good prognosis was the presence of deep pain perception, and in the second case the prognosis was determined by the presence of sensitivity and anal sphincter tone during the initial neurological examination.

Andropogon grass consortium with stylo in two times: the forage response and sources of phosphorus rates

The use of legumes intercropped with forage in the Brazilian savannah (Cerrado) region is an alternative to reverse the process of pasture degradation. The natural phosphorus deficiency in this region and the high retention capacity of this nutrient in the soil are factors that directly affect the sustainability of the production system. The objective of this study was to evaluate the effect of a phosphate with medium solubility (Arad) compared to more soluble sources such as triple superphosphate and mono-ammonium phosphate, on the formation and maintenance of pastures of Andropogon gayanus with or without the introduction of Stylosantes guianensis in pasture already established in the Brazilian savannah. Two experiments were carried out under field conditions in an Oxisol using a randomized block design with split plots, plots with two sources of phosphorus (Arad and super-triple or MAP) and subplots with different levels of phosphorus. The study showed that andropogon grass, even though characterised as forage requiring low fertilization, responded to increased fertilization, especially with the use of more soluble sources of P at planting. From the second year on, with the introduction of Stylosantes guianensis, verified effects were seen on legumes in their efficiency of utilization of residual fertilization from the first year; however, this didn't affect legume dry matter production resulting from the P sources used for the andropogon grass. The mixed stands of andropogon grass and Stylosantes guianensis made it more advantageous to increase the P sources using phosphate fertilizer with lower solubility (Arad), when compared to MAP.

Estudo da estabilidade da cirurgia do tipo sagital da mandíbula com vista a correção de deformidades faciais

This research evaluated the surgical stabilily in patients with mandibular prognathism and retrognathism in which was used sagital split technic to correct those detormities. Twelve patients were selected from the clinic of only one experienced surgeon. Six patients presenter a Class III 6 a Class II molar relationship. A comparative cefalometric analysis using linear and angular measurements was performed of pre-surgery, imediate pós-surgery and 1 year follow-up. The following conclusions were obtained. 1 The Dal Pont sagital split technic modified by Epker to correct mandibular prognathisn and retroghnatism is a stable technic and must be indicated to correct those deformities. 2 Small relapses are easily corrected by the post-surgical orthodontic treatment. 3 A small over correction is advised in cases of large mandibular advancements or set bascks. 4 In those cases which a large amount of mandibular retrusion on advancement need to be performed, a combination of maxillary and mandibular surgery should be used. Rigid fixation technic is also indicated in those cases
