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.

Cats are gradually occupying a more important position as pets and this preference is a result of how easy cat maintenance in an urban environment is, even though they are very prolific and need surgical sterilization. This paper aims at evaluating obtained data within 15 years of research in a university service program that offers free cats sterilization surgery. We carried out a statistical analysis of data shown in the records of animals treated by the program. Surgical sterilization was performed on 647 animals (409 females – 63% and 238 males – 37%). Unilateral cryptorchidism was observed in 9 (3.8%) male cats. Forty (10%) female cats were pregnant at the time of the surgery and the treatment with contraceptives was observed in 67 (16.4%) female cats. One death occurred during anesthesia recovery and 2 cats were euthanized because of wound infection, totalizing an amount of 0.5% of severe complications. From 1996 to 2004, 212 female cats were spayed (122 adults and 90 prepubertal) and during that time two different approaches for ovariohysterectomy were compared: flank laparotomy and ventral midline celiotomy. The flank laparotomy approach was used in only 46 female cats (21.7%) due to some disadvantages observed – the need of an incision on each flank in prepubertal or nulliparous animals and the difficulty or impossibility of total uterus removal. In the same period, 105 male cats underwent orchiectomy via an open technique in which the spermatic cord was linked with nylon thread. From 2005 to 2010, 197 females (106 adults and 91 prepubertal) were spayed. The minilaparotomy technique was used to perform ovariohysterectomy on 139 female cats (70.6%). In this procedure, ovaries and uterus were exteriorized in a blind fashion with a hook through a small midline incision. The traditional midline ovariohysterectomy, which incision length permits direct visualization of the ovaries and uterus, had to be performed in 58 (29.4%) female cats due to advanced pregnancy, full urinary bladder during surgery or obesity. Over the past 6 years, 133 male cats (48 adults and 85 prepubertal) were castrated by means of an open technique in which the spermatic cord was tied to itself. The demand for surgeries during the project demonstrated that people are becoming aware concerning the importance of sterilization when facing cat overpopulation and abandonment.

The aim of this work was to evaluate the electrocardiography effects (ECG), sedation time and quality of recovery due to buprenorphine (G1) and butorphanol (G2) administration in dogs pretreated with acepromazine. Seven adult dogs were submitted to both protocols, with a thirty days interval between groups. G1 animals were premedicated with acepromazine (0.1 mg/kg) followed 10 minutes later with buprenorphine (0.005 mg/kg), both applied intravenously. The same procedure was performed for G2 employing butorphanol (0.3 mg/kg) instead of buprenorphine. The measurements of the variables heart rate (HR), duration and amplitude of P wave, P-R intervals (PR), QRS complex duration, R wave amplitude, Q-T intervals (QT) and R-R intervals (RR) were taken immediately before application of acepromazine (M0), 10 minute after administration of acepromazine (M10) and 10 minutes after opioids administration (M20). Serial measurements were carried out in 10 minute intervals after the administration of butorphanol or buprenorphine up to 60 minutes. Numeric data were submitted to Tukey Analysis (p < 0.05). The amplitude of P wave decreased 30 minutes after the administration of the butorphanol. Sedation time was longer in G1 (78 minutes) than G2 (72 minutes) and recovery was good in both groups. These results indicate that butorphanol or buprenorphine produced discreet alterations on ECG, which don´t contraindicate its clinical use.

To treat periodontal disease is essential to establish a control in all etiological factors that cause destructive activity in periodontal tissues. Basic periodontal therapy may be applied to eliminate or/and to control all etiologic factors involved in disease development. In this paper, some aspects to stabilize advanced periodontal disease using basic periodontal therapy are analyzed and discussed.

The association between emotional stress and intense bruxism has as consequence the Temporomandibular Disorder (TMD), which is an increasingly apparent problem at the dental clinic, requiring judicious means of diagnosis and especially treatment.. Several factors, of equivalent importance, may be related to the DTM, one of them is the loss of vertical dimension of occlusion (VDO), and parafunctional habits and also the loss of stable contacts between the posterior teeth or lack thereof, which generates an increase functional anterior teeth for excessive wear or buccal and consequent.. This paper proposes using a clinical case, to present and discuss the steps for clinical diagnosis, planning and execution of oral rehabilitation with Fixed Partial Denture for restoring vertical dimension of occlusion in a patient with severe parafunction.. Oral rehabilitation of these patients should be carefully planned, respecting the functional and aesthetic aspects.. The parafunction control by monitoring the Temporomandibular Disorder is essential to the longitudinal prediction of rehabilitation performed in these types of rehabilitative treatment.

Introdução: a ausência ou alterações da estrutura dentária, principalmente em áreas estéticas, compromete a aparência, as relações sociais, a autoestima e, consequentemente, a qualidade de vida do indivíduo. Atualmente, avanços tecnológicos e científicos na Odontologia têm possibilitado várias opções de tratamentos reabilitadores e restauradores que oferecem resultados cada vez mais seguros e confiáveis. Objetivo: relatar, por meio de um caso clínico, a recuperação da harmonia dos dentes anteriores com a utilização de laminados de cerâmica e prótese sobre implante associada a recursos para recuperar a estética gengival. Conclusão: o planejamento adequado, associado aos conhecimentos de uma Odontologia integrada, possibilita resultados extremamente satisfatórios, resgatando a função e a estética, tanto dentária quanto gengival, proporcionando um sorriso harmonioso e o bem-estar social do paciente.
