Published: August 2015

Several systemic diseases and their medical treatment may predispose the development of aggressive dental caries. Head and neck radiotherapy, chemotherapy, Sjögren's syndrome and long-standing treatment with drugs that induce hyposalivation are some of these conditions. The aim of this article is to describe the clinical features of five patients who developed chronic graft-versus-host-disease (cGVHD) as a complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT) and, in spite of close dental follow-up, subsequently developed rampant caries. In these cases, the restorations showed early failure and the caries still progressed until generalized teeth destruction. The majority of the teeth therefore had to be extracted due to advanced dental caries and rapid clinical progression. Herein the term "cGVHD-related caries" is proposed to describe this under-recognized complication of cancer treatment that may evolve in allo-HSCT recipients that develop cGVHD. This condition is poorly recognized in the literature and may represent the final result of the clustering of oral complications in cGVHD patients, including mucositis, oral pain, hyposalivation, taste loss and oral infections, leading to rampant caries due to impaired oral hygiene and increased intake of highly cariogenic food. Consequently, the knowledge of this oral complication should improve the medical and dental management of cGVHD oral manifestations and improve the quality of life of patients with this post allo-HSCT complication.

Failures may occur in the connections of dental implants, especially in external hexagon (EH). Due to the deformations in this portion of implants, this study aimed to evaluate the levels of deformation of EH connections subjected to internal toque. Two types of implants were used: N group and S group. Torques of 0, 32, 45, 60 and 80 Ncm were applied to the N group, and torques of 0, 30, 40, 60 and infinite Ncm were applied to the S group implants. The internal distance (ID), internal area (IA) and external area (EA) of the EH were obtained from digital pictures, which were analyzed by a specific software. Statistical analysis was performed by the Scott-Knott test. The results showed that the higher the torque applied, the greater were the changes in the evaluated dimensions in both groups. In the S group, torque levels equal or greater than 40 Ncm and 30 Ncm caused greater deformation of EA and IA respectively, while in the N group, torque levels equal or greater than 60 Ncm and 32 Ncm caused greater deformation of EA and IA respectively. Levels of deformation were greater in the S group as compared with the N group. These findings suggest that the IA, EA and ID of the EH may be affected by different internal torque levels.

The aim of the present study was to evaluate parental perceptions of oral health status in preschool children. A cross-sectional study was carried with 843 Brazilian children between 3 and 5 years of age. Parents/guardians answered a self-administered questionnaire on the health of their children and sociodemographic data. Parental perceptions of their child's oral health were determined by the responses to the following question: "How would you describe your child's oral health?" The Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS) was answered by parents/guardians and used to measure the impact of oral health-related quality of life (OHRQoL) on preschool children and their families. Three examiners performed oral exams on the children (K= 0.85-0.90). Descriptive analytical statistics were carried out, followed by logistic regression for complex samples (α=5%). The following variables were significantly associated with parental perceptions of children's oral health: parental perception of general health as poor (OR=18.25; 95% CI: 3.36-98.96), negative impact on family's OHRQoL (OR=13.82; 95% CI: 4.27-44.72), child aged five years (OR=7.40; 95% CI: 1.49-36.63) and the interaction between history of toothache and dental caries (OR=10.02; 95% CI: 1.17-85.61). Thus, parental perceptions of oral health are influenced only by clinical conditions with symptoms, such as dental caries with toothache. Other oral conditions, such as malocclusion or traumatic dental injury, were not associated with parental perceptions of their child's oral health.

Published: August 2015

Carcinoma ex pleomorphic adenoma (CXPA) has been considered an interesting model of carcinogenesis, presenting various histological subtypes and invasiveness phase. The objective was to determine the proliferative index of CXPA and comparing to pleomorphic adenoma (PA). Thirty six cases of CXPA (36 PA) and 22 areas of PA in CXPA (residual PA) were studied by Ki-67 expression. All CXPA cases were classified according to invasiveness phase (intracapsular, minimally and frankly invasive) and histopathological subtypes. Data was statistically analyzed by Wilcoxon, Mann-Whitney and Kruskal-Wallis tests. CXPA included 5 intracapsular, 9 minimally invasive and 22 frankly invasive cases. Fifteen cases corresponded to salivary duct carcinoma, 7 to adenocarcinoma NOS, 7 myoepithelial, 5 epithelial-myoepithelial, one case of squamous cell and one case of sarcomatoid carcinoma. The Ki-67 index of PA and residual PA were significantly lower than CXPA. Intracapsular and minimally invasive showed smaller proliferative index than frankly invasive. Considering the subtypes of CXPA, there was not a statistic difference among them. Ki-67 is a useful marker in the differential diagnosis of PA and CXPA, even when in the early invasive phase.

Published: August 2015

This study evaluated the color change, cytotoxicity and hydrogen peroxide (HP) diffusion caused by different home bleaching protocols: 10% carbamide peroxide (CP) for 3 or 1.5 h, 6% hydrogen peroxide for 1.5 h or 45 min. To quantify the peroxide penetration, disks of bovine teeth were placed in artificial pulp chambers (APCs) containing acetate buffer, which was collected for evaluation in a spectrophotometer. For analysis of cytotoxicity, specimens were adapted in APCs containing culture medium, which subsequently was applied on MDPC-23 odontoblast-like cells for 1 h. Cellular metabolism was evaluated by methyl tetrazolium (MTT) assay and the color change of the specimens was analyzed using the CIE L * a * b * system. The data were submitted to ANOVA and Fisher test (α=5%). The treatment with 10% CP for 3 h was the most effective, and 6% HP for 45 min produced the lowest color change. The groups 10% CP for 1.5 h and 6% HP for 45 min had the lowest trans-enamel dentinal HP penetration, and the 6% HP for 1.5 h had the highest. None of the protocols affected cellular metabolism and morphology. In conclusion, reduced peroxide exposure time reduced the bleaching result; higher HP diffusion did not mean higher effectiveness.

Published: August 2015

The aims of this study were to evaluate quantitatively the enamel fractures, adhesive remnants and bracket fragments on enamel after debonding of metal and ceramic brackets, and to quantify the layer of adhesive remnants in depth after two different cleanup procedures. Metal and ceramic brackets were bonded on 120 human incisors and then debonded using two different techniques with Side Cutter (SC) and Anterior Bracket Removal plier (ABR). After this, a high-speed tungsten carbide finishing bur or a low-speed tungsten carbide finishing bur was used. The debonded samples were submitted to enamel assessment with optical coherence tomography (OCT). In sequence, two different methods of removing the remaining adhesive (tungsten carbide burs at high and low speed) were performed and at the end of these procedures, the remaining adhesive layer was measured with OCT. The results demonstrated that enamel fractures were observed only in the samples bonded with ceramic brackets, and the type of pliers did not influence the incidence and extent of enamel damage. Moreover, the type of debonding technique (with side-cutting pliers or anterior bracket removal pliers) and the type of bracket did not influence the amount of adhesive remaining after debonding. The burs at low speed removed the remaining adhesive more effectively during cleanup procedures.

This study evaluated the tension force of cast frameworks made by the technique of framework cemented on prepared abutments using two different resin cements. Forty multi-unit abutment analogs were individually fixed with chemically cured acrylic resin inside PVC cylinders using a parallelometer. Brass cylindrical abutments were tightened to the multi-unit abutments to be used as spacers and then castable UCLA abutments were positioned above. These abutments were cast with Ni-Cr and then divided into 4 groups (n=10): cemented with RelyX U100(r); cemented with RelyX U100(r) and simulation of acrylic resin polymerization process; cemented with Multilink(r); and cemented with Multilink(r) and simulation of acrylic resin polymerization process. Abutments were cemented according to manufacturers' instructions. In a universal testing machine, tensile strength was applied in the direction of the long axis of the abutments at 1 mm/min crosshead speed until displacement of the luted abutments was obtained. The values of maximum tensile force (N) required for the displacement of the luted abutments were tabulated and analyzed statistically by one-way ANOVA with a 95% confidence level. No statistically significant difference was found among the groups (p>0.05). There was an increase in mean tension force when the specimens were subjected to the simulation of acrylic resin polymerization process, but the results did not differ statistically. Both resin cements presented positive results as regards the retention of luted abutments on their respective multi-unit abutments. Both materials may be indicated for the technique of framework cemented on prepared abutments when professionals pursuit better adaptation of implant-supported frameworks.

Published: August 2015

This study evaluated retrospectively the effect of fusidic acid on the management of desquamative gingivitis (DG). The study population consisted of 15 patients with DG. Patients were requested to make topical application of 2% fusidic acid ointment 4 times a day for 6 weeks. Clinical assessments were recorded at baseline, at 6 weeks and 12 months after beginning the therapy. Patients' examination involved lesion size area, pain score and impact on daily activities. All patients presented lesions in maxilla; in 9 patients (60.0%) lesions were predominately at the anterior region and 6 (40.0%) at the posterior region of maxilla. Treatment significantly (p<0.05) reduced the pain intensity (from 5.4±1.12 to 1.16±0.97) and its periodicity (from 53.33% with pain>3 x/week to 13.33%), and the lesion size in 72.47% (±4.12) immediately after 6 weeks of treatment. Improvements were sustained for 12 months compared to baseline (p<0.001). It also reduced the impact of disease in daily activities (eating and oral hygiene performance), and improved the emotional condition of patients, who reported better social relationships and habits. Topical application of fusidic acid may be a possible alternative local palliative therapy for desquamative gingivitis treatment.

To determine the frequency of apical and cervical curvatures in human molars using the radius method and cone-beam computed tomography (CBCT) images. Four hundred images of mandibular and maxillary first and second molars were selected from a database of CBCT exams. The radius of curvature of curved root canals was measured using a circumcenter based on three mathematical points. Radii were classified according to the following scores: 0 - straight line; 1 - large radius (r>8 mm, mild curvature); 2 - intermediate radius (r>4 and r<8 mm, moderate curvature); and 3 - small radius (r≤4 mm, severe curvature). The frequency of curved root canals was analyzed according to root canal, root thirds, and coronal and sagittal planes, and assessed using the chi-square test (significance at α=0.05). Of the 1,200 evaluated root canals, 92.75% presented curved root canals in the apical third and 73.25% in the cervical third on coronal plane images; sagittal plane analysis yielded 89.75% of curved canals in the apical third and 77% in the cervical third. Root canals with a large radius were significantly more frequent when compared with the other categories, regardless of root third or plane. Most root canals of maxillary and mandibular first and second molars showed some degree of curvature in the apical and cervical thirds, regardless of the analyzed plane (coronal or sagittal).

Os objetivos neste estudo foram avaliar os efeitos da radiação γ sobre a sobrevivência e desenvolvimento de gemas de segmentos caulinares e germinação de sementes de maracujazeiro-amarelo (Passiflora edulis f. flavicarpa) in vitro. Os explantes de segmentos caulinares (2cm) contendo uma gema axilar, obtidos a partir de plântulas provenientes da germinação in vitro de sementes de maracujá, foram tratados com raios γ em dosagens variando de 10 a 60Gy e subsequentemente transferidos para meio Murashige e Skoog (MS), suplementado com 4,0mg L-1BAP. Para a irradiação das sementes, foram testadas doses que variaram de 75-200Gy e a germinação e sobrevivência das plântulas foram avaliadas após 30 e 60 dias da inoculação em meio MS, respectivamente. Após 30 dias da irradiação de segmentos caulinares, observou-se redução de 50% na sobrevivência dos explantes e no número de brotações formadas in vitro nas doses de 21,31 e 12,20Gy, respectivamente. A DL50 para a germinação de sementes é 160Gy, enquanto que, para sobrevivência das plântulas, é de 125Gy.

A deficiência de B pode diminuir a fertilidade das flores, prejudicando a produtividade de sementes de trigo. O trabalho objetivou avaliar a produção e a qualidade fisiológica de sementes de trigo produzidas sobre épocas e doses de aplicação de B. O experimento foi desenvolvido no laboratório didático de análise de sementes e em casa de vegetação, no município do Capão do Leão (RS). O delineamento experimental utilizado foi completamente casualizado, com quatro repetições e em esquema fatorial, envolvendo estádio de aplicação (semeadura e perfilhamento), e doses de B (0, 1, 2, 3, 4 e 5kg B ha-1). A fonte de B utilizada foi o tetraborato de sódio (boráx), o qual apresenta 11,5% de B. A adubação boratada, aplicada na semeadura ou perfilhamento, em doses entre 2,5kg e 3kg de B ha-1 ocasionam aumento no número de sementes e espigas produzidas por planta, redução do rendimento de sementes por planta, peso de mil sementes e o peso hectolítrico, sem causar redução na qualidade fisiológica de sementes de trigo. As plantas de trigo apresentam maior absorção de B na aplicação no estádio de perfilhamento, em relação à fase de semeadura.

Foram avaliados os efeitos da inclusão de grãos de girassol ou gordura protegida na dieta e da restrição e realimentação sobre a área de olho de lombo, espessura de gordura subcutânea, a composição centesimal, o teor de colesterol e a composição em ácidos graxos da gordura intramuscular do Longissimus lumborum de cordeiros, distribuídos em delineamento inteiramente casualizado, em esquema fatorial (3 dietas x 2 manejos de alimentação). O colesterol da gordura intramuscular de cordeiros alimentados com a dieta contendo gordura protegida (28,5mg 100 g-1) foi menor (P<0,05) que o do controle (36,8mg 100g-1) e grãos de girassol (38,1mg 100g-1). O manejo de restrição alimentar e realimentação não modificaram (P>0,05) o perfil dos ácidos graxos, porém foi detectado que a dieta contendo grãos de girassol elevou (P<0,05) a razão polinsaturado/saturado, provavelmente pela superioridade (P<0,05) de 20% na proporção de polinsaturados, reflexo direto do aumento na concentração do ácido linoleico. A inclusão de fontes lipídicas na dieta de ovinos é ferramenta que contribui para melhorar a qualidade da gordura intramuscular de cordeiros confinados, considerando que a gordura protegida reduz o teor de colesterol e que os grãos de girassol aumentam a concentração de ácidos graxos polinsaturados. O manejo de alimentação com período de restrição e realimentação não altera a composição centesimal e a qualidade da gordura intramuscular.
Instance selection in digital soil mapping: a study case in Rio Grande do Sul, Brazil

Published: August 2015

A critical issue in digital soil mapping (DSM) is the selection of data sampling method for model training. One emerging approach applies instance selection to reduce the size of the dataset by drawing only relevant samples in order to obtain a representative subset that is still large enough to preserve relevant information, but small enough to be easily handled by learning algorithms. Although there are suggestions to distribute data sampling as a function of the soil map unit (MU) boundaries location, there are still contradictions among research recommendations for locating samples either closer or more distant from soil MU boundaries. A study was conducted to evaluate instance selection methods based on spatially-explicit data collection using location in relation to soil MU boundaries as the main criterion. Decision tree analysis was performed for modeling digital soil class mapping using two different sampling schemes: a) selecting sampling points located outside buffers near soil MU boundaries, and b) selecting sampling points located within buffers near soil MU boundaries. Data was prepared for generating classification trees to include only data points located within or outside buffers with widths of 60, 120, 240, 360, 480, and 600m near MU boundaries. Instance selection methods using both spatial selection of methods was effective for reduced size of the dataset used for calibrating classification tree models, but failed to provide advantages to digital soil mapping because of potential reduction in the accuracy of classification tree models.

Published: August 2015

Acute erythroid leukemia (AML M6) is a hematopoietic neoplasm frequently described in cats and mice, rarely in other animal species. This report describes a case of AML M6 in a yearling Thoroughbred filly. Clinically the horse presented marked pale mucous membranes and exercise intolerance. In addition, the owner and referring veterinarian reported a 30-day history of progressive weight loss. The CBC revealed severe anemia and leukopenia by neutropenia. Cytology evaluation obtained from bone marrow fine needle aspirates evidenced inversion of the myeloid: erythroid ratio (0.2), with 48% of the nucleated cells corresponding to rubriblasts. In addition to the gross evidence of anemia, necropsy findings consisted of splenomegaly and lymphadenomegaly. The diagnosis of AML M6B was confirmed histologically due to splenomegaly and lymphadenomegaly, secondary to neoplastic metastasization.

Methodological variations in the amount of sample incubated and the type of rumen fluid used are commonly observed. This study evaluated the effect of three sample amounts (0.6, 1.3 or 2.6g DM 100mL-1 of rumen fluid) incubated in rumen fluid buffered (BRF-buffered rumen fluid) or not (PRF-pure rumen fluid) on total gas volume (TV), methane (CH4) production, dry matter degradation (DM Deg) and final pH of corn silage incubated in vitro. The highest DM Deg was reached with the lowest amounts of sample (0.6 and 1.3g of DM 100mL-1 of rumen fluid). The sample amount of 2.6g associated with PRF reduced CH4 production (P<0.05), compared with the amounts of 0.6 and 1.3g DM 100mL-1, which had similar CH4 production (P>0.05). The use of BRF caused no effect on CH4 production (P>0.05), independent of the sample amount. Increasing the amount of substrate resulted in lower final pH of incubation in both fluids (P<0.05). Our results indicate that incubations should be performed with the smallest amount of sample (0.6g of DM 100mL-1 of rumen fluid), using fluid without buffer. Incubation without buffer solution overestimates the CH4 production of corn silage. Further studies should be conducted to verify the possibility of in vitro ruminal incubation of other ingredients using pure rumen fluid.

A obtenção de estimativas confiáveis de parâmetros genéticos, incluindo dados relacionados à variabilidade das populações sob melhoramento, é essencial para se elucidar a estrutura genética das populações e para se inferir sobre sua variabilidade genética e seu potencial de melhoramento. Nesse sentido, este trabalho teve por objetivo estimar parâmetros genéticos e a diversidade em progênies de Macaúba com base em características morfológicas e fisiológicas. Para o estudo, foram avaliadas características morfológicas e fisiológicas em 15 progênies de macaúba, em delineamento em blocos ao acaso com 5 repetições e 3 plantas por parcela, no espaçamento de 5x5m. Não houve variabilidade para a maioria das características fisiológicas no conjunto de progênies avaliadas. Porém, verificou-se variabilidade genética para os caracteres morfológicos avaliados. As famílias de macaúba agruparam-se em três grupos distintos quanto à diversidade genética, sendo a família CPAC-03 a mais divergente em relação às demais. A eficiência no uso da água e o comprimento de raquis foram as características que mais contribuíram para a dissimilaridade das famílias de macaúba.

O sucesso de um cultivo consorciado esta relacionado com o conhecimento de todos os fatores que afetam o crescimento e produção das espécies. Objetivou-se neste trabalho avaliar a produção de grãos de milho sob diferentes manejos de plantas daninhas e arranjos de plantio em sistema agrossilvipastoril. O delineamento experimental foi em blocos casualizados, com três repetições. Os tratamentos foram dispostos no esquema de parcelas subdivididas, sendo as parcelas correspondentes aos sistemas de consórcio: eucalipto ou eucalipto junto com acácia consorciada com milho eBrachiaria brizanthacv. 'Marandu' ou B. decumbenscv. 'Basilisk' ou B. brizanthacv. 'Piatã'. Nas subparcelas, alocaram-se os sistemas de manejo de plantas daninhas: atrazine aplicado isoladamente ou mistura em tanque do atrazine com subdose do nicosulfuron. Adicionaram-se duas testemunhas relativas ao milho em monocultivo nos dois sistemas de manejos de plantas daninhas. As espécies florestais foram transplantadas na ocasião da semeadura do milho e das braquiárias, realizada em plantio direto. A aplicação de nicosulfuron em mistura com atrazine promoveu o aumento da altura de plantas e inserção de espigas, sem influenciar na produtividade de grãos de milho. O eucalipto, acácia e as espécies de braquiárias, estabelecidos concomitantemente, não influenciaram na produtividade de milho. A produtividade de grãos de milho é reduzida no sistema agrossilvipastoril em relação ao monocultivo.

Published: August 2015

A fisiopatologia da hiperplasia prostática benigna (HPB) não está totalmente compreendida, no entanto, a diidrotestosterona é o principal hormônio envolvido. Recentemente, o efeito da toxina botulínica A (TB-A) foi investigado, mostrando que esta induz atrofia do parênquima e redução do volume prostático. Com base nisso, este estudo teve como objetivos comparar os efeitos da administração da TB-A com a orquiectomia no tratamento da HPB, além de avaliar os efeitos da TB-A sobre a libido e qualidade do sêmen. Para tanto, 16 cães adultos foram submetidos à castração ou administração de 500U de TB-A, e avaliados durante 16 semanas. A orquiectomia mostrou-se um excelente tratamento, promovendo redução de 80% do volume prostático. Aplicação da TB-A não ocasionou alterações na libido, ereção ou qualidade e características seminais. Por outro lado, reduziu significamente o volume da próstata. Os resultados sugerem que a administração intraprostática de TB-A é um tratamento alternativo efetivo e sem efeitos colaterais para cães destinados a programas de reprodução. No entanto, esta terapia apresenta reduções inferiores do volume prostático, quando comparada com a orquiectomia.

O objetivo deste trabalho foi comparar a capacidade discriminatória de métodos para seleção e recomendação de clones de cafeeiros da espécie Coffea canephora, considerando a interação genótipos x anos na distribuição da produtividade de café beneficiado, nos períodos de 2000 a 2004 e de 2007 a 2011. O efeito significativo da interação genótipos x anos indicou que existem clones que apresentaram desempenho não consistente ao longo do tempo. Os métodos de LIN & BINNS (1988) e ANNICCHIARICO (1992) apresentaram resultados similares, de modo que um deles pode ser utilizado em substituição ao outro. O método de EBERHART & RUSSEL (1966) identificou parte dos clones de adaptação específica, enquanto que os métodos, MHPRVG e centroide permitiram caracterizar os clones de maior adaptabilidade e estabilidade, apresentando resultados complementares. A seleção de plantas baseada na distribuição da produtividade de café beneficiado ao longo do tempo permitiu selecionar clones de desempenho superior sem acentuar a bienalidade.

Ipomoea carnea is a toxic plant that grazing goats and cattle may learn to ingest with repeated exposure. The objective of this study was to evaluate the feeding preferences of experienced and non-experienced (naïve) goats and sheep for I. carnea.The study used 3 groups of 5 goats (Group 1, experienced that were previously poisoned by the plant; group 2, naïve; Group 3, experienced eaters, composed of animals adapted to eat the fresh plant) and 2 groups of sheep (group 4, experienced that were previously poisoned by the plant; and group 5, naïve). For the test, the animals were placed daily for 10 minutes and 4 days in a rectangular stall (5x7m) with 4 feeders, each with 200g of a different food (Ipomoea carnea, commercial concentrate food, recently harvested green grass (mainly Brachiaria spp.), and Cynodon dactylonhay. The intake of concentrate food was significantly higher (P<0.05) than the consumption of green grass, hay and I. carnea. In a second 4 day trial, in which the commercial concentrate food was replaced by freshly harvested Amorimia septentrionalis, the ingestion of green grass (Brachiaria spp.) was significantly higher (P<0.05) than the consumption of other foods. In both trials there was no significant difference in food consumption between eaters and naïve animals. The results suggest that experienced or naïve sheep and goats do not prefer I. carnea when it is offered with other foods or forages, suggesting that animals will avoid the plant and not become poisoned if other food options are available.

Ochratoxin A (OTA) is a mycotoxin with nephrotoxic, genotoxic, teratogenic and carcinogenic properties. The presence of this toxin in wines and juices occurs due to the development of toxigenic fungi in grapes. Studies have shown the presence of this toxic secondary metabolite in these beverages may results in economic losses to the winery as well as health problems for consumers. In Europe, several studies have been done in order to map the areas where the development of ochratoxigenic fungi is more favorable. However, in Brazil these studies are still incipient. The Joint Expert Committee on Food Additives of the World Health Organization (JECFA) established the safe tolerable intake of 112ng OTA per kg of body weight per week. To verify whether the population is exposed to OTA levels that pose a risk to health is necessary to compare the parameter of safe ingestion defined by JECFA with the levels of exposure to this toxin. Periodic monitoring of the OTA levels in food and beverage has been justified by some reasons including: (i) the toxic effects of this toxin, (ii) the recent publication of the Brazilian legislation establishing maximum limit for OTA, (iii) the introduction of grape juice in school meals and (iv) the recommendation of regular wine intake because of their functional properties.

This study aims to verify, accurate and precisely, the responses of Italian ryegrass 'BRS Ponteio' cultivar to different frequencies of defoliation for forage production and especially for seed production. For this purpose, a randomized block design experiment with four replications was conducted. Four frequencies of defoliation were applied (zero, one, two, and three) based on the thermal sum, evaluating the rate of leaf appearance (LAR), phyllochron (P), leaf expansion rate (LER), leaf senescence rate (LSR), stems expansion rate (SER), tillering rate (TR), leaf life span (LL), forage production, proportion of leaf blades, stems plus sheaths, senescent material, and inflorescences, as well as seed production. Second defoliation noticeably altered the morphogenic plant responses, reduced expansion rates and leaf appearance, increased rates of tillering and stems expansion. This phenotypic maintained a high seed production and provided a harvest of forage mass 100% higher than the collected mass in the first cutting. Third defoliation led to an increase of 100% of the harvested forage mass; however, it caused drastic and negative changes in the morphogenic characteristics and seed yielding.

Citrus are attacked by pest mites such as the citrus rust mite Phyllocoptruta oleivora (Ashmead) (Acari: Eriophyidae) and the spider mite Tetranychus mexicanus (McGregor) (Acari: Tetranychidae). However, little is known on citrus rootstocks influencing pest mites. We aimed to evaluate the influence of rootstocks on population densities of pest mites on the sweet oranges 'Pera CNPMF D-6' and 'Valencia Tuxpan' throughout time. Adults of both mite species were monthly counted during 19 months from June 2011 to February 2013. Rootstocks influenced the populations of pest mites, since lower densities of P. oleivora were found on 'Pera CNPMF D-6' sweet orange grafted on the hybrid TSKC × CTTR - 002 and on 'Swingle' citrumelo in comparison with the hybrid LVK × LCR - 010, 'Red' rough lime and 'Santa Cruz' rangpur lime as rootstocks. Similarly, lower densities of T. mexicanus were found on 'Valencia Tuxpan' sweet orange grafted on the hybrid HTR-051 in comparison to 'Indio' citrandarin, 'Sunki Tropical' mandarin and LVK × LCR - 010 as rootstocks. We concluded that densities of the mites P. oleivora and T. mexicanus on the sweet oranges 'Pera CNPMF D-6' and 'Valencia Tuxpan' were affected in some periods of the year by some rootstocks, suggesting influence of some genotypes on these pests.

Published: August 2015

The aim of this study was to understand the nursing work organization in long-stay institutions for the elderly and its relationship to pleasure and suffering at work. Data were collected through observation and interviews between April and September 2013 and submitted to content analysis, in light of Dejours' psychodynamics of work theory. Professionals experience suffering as they face physical exertion, a fast-paced work environment and repetitive routines, limited human resources, accumulation of responsibilities and lack of medical service in the institution. Pleasure is experienced through the division of labor among workers, staff's good working relationships, freedom to change the work organization and the possibility of creating a bond with the elderly. The study provides subsidies for planning adequacies in the nursing work organization at these institutions, which will improve the workers' relationship to their work activities.

Published: August 2015

This study aimed to describe management and implementation of care for women hospitalized due to an abortion, from the perspective of nursing professionals. A qualitative study performed in an obstetric hospital unit of a University Hospital in the extreme South of Brazil, by means of a semi-structured interview with 19 nursing professionals. For the analysis, the Collective Subject Discourse technique was used. The statements were ambivalent. Some nursing professionals reported interference in discriminatory behavior and little interaction with the woman, resulting in care being organized with a focus on clinical aspects. Others considered care to be appropriate, regardless of the etiology of abortion, pointing out some humanized initiatives such as emotional support and provision of a private therapeutic environment. This research broadens the range of information about the management and implementation of care for women hospitalized due to abortion, highlighting the importance of articulating perceptions, feelings and ethical behavior with actions to plan, manage and provide care.

Published: August 2015

The aim of this study was to identify the prevalence of drug use by pregnant women assisted in primary care; classifying the medications used according to the risk according to the Food and Drug Administration and grouping drugs used according to the Anatomical Therapeutic Classification. A cross-sectional analytical study was developed in Maringá, Paraná. Data were collected between January and July 2012 through semi-structured interviews in households. The sample comprised 394 pregnant women at different gestational ages. Results revealed that 94.67% of the pregnant women (2.03%) used at least one medication without medical prescription and the most used drugs were antianemics, followed by antiemetics and analgesics. Data showed a statistically significant relationship between the use of medicines and marital conditions, trimester of pregnancy, chronic disease, mental illness and orientation of professionals at the Basic Health Units about medicines. It is noteworthy that, given the complexity of the theme, health professionals, especially nurses, should approach the subject in the care of pregnant women.

This study aimed to identify the values of modern nursing in the writings of Florence Nightingale entitled Notes on Nursing: What it Is, and What it Is Not, and justify them through some of the assumptions of Max Scheler's axiology. For this, we used Wilhelm Dilthey's hermeneutics as an instrument to unveil the Nightingale axiological field. From the effort undertaken in the search for the interpretation of the text, four core values of modern nursing were revealed from the researchers' consciousness, namely: solidarity; the value of truth; morality; and utility. These values form an amalgam and give nursing care sense and meaning. We concluded that these values make nursing what it is, legitimizing it as a social practice, and justifying the professional act. Thus, it is necessary for whoever undertakes this career to move themselves to the apprehension of values that form the axiological field, correcting or confirming the value of a scale itself, in order to form what it is to be a nurse.

The aims of this study were: to identify the therapeutic activities of a psychosocial care center specifically for family members, and to consider whether the care offered provided benefits to the relationship between the family and alcohol users. This was a qualitative research study, and included 15 families of alcohol users from Minas Gerais. The data collection occurred during January and March of 2012. Thematic analysis was used. The analysis identified three themes: 1) relationship: before and after the initiation of treatment in the service; 2) assistance for the family; 3) treatment suggestions. The results showed that the care in the service contributed to improving the family relationship, but families provided some suggestions to improve this care. We concluded that the service was an important provider of social support for improving the family relationship.

Published: August 2015

Socio-historical and qualitative study aiming to rescue the establishment process of the Regional Nursing Council of Santa Catarina and characterize its importance to the profession. It presents its theoretical support on the ideas of Eliot Freidson and New History. In the method, oral history and documentary research were used, involving eight nurses who implemented the representative organization in the referred time frame. The principles of Content Analysis guided data analysis, which were organized according to the mandates of the Regional Nursing Council of Santa Catarina from 1975 to 1986. During the implantation of the professional Council, there was a fragile notion about the objectives of the council and a slow supervision process. It is concluded that the importance of the establishment of the profession Council was known by the leaders and little understood by all professionals in the state.

Resumo

Os marcadores cardíacos, sobretudo a CK-MB massa e a cTnI, tem demonstrado um papel essencial seja em cardiologia clínica ou cirúrgica veterinária e humana, permitindo um diagnóstico mais preciso e acurado nas lesões miocárdicas. O objetivo deste trabalho foi mensurar os marcadores cardíacos em tela na Medicina Veterinária, aprimorar sua utilização e obter informações sobre estes métodos laboratoriais não invasivos que permitem o monitoramento da integridade da célula miocárdica. A quantificação dos parâmetros foi feita do soro de cães saudáveis atendidos na rotina do setor de Clínica Médica de Pequenos Animais do Hospital Veterinário da Universidade Estadual do Norte Fluminense Darcy Ribeiro. O kit de ensaio imunométrico por quimioluminescência turbo (IMMULITE Turbo, Siemens®) humano mostrou-se eficaz na avaliação na espécie canina, tanto para CK-MB massa quanto cTnI. Além disso, os valores encontrados para CK-MB massa e cTnI contribuirão significativamente para a rotina clínica ou para os trabalhos experimentais em cães.
