The consumption of exotic fruits has been showing accentuated increase and the cultivated area is in expansion, generating demand for adequate culturing techniques. The Malay apple (Syzygium malaccense), with probable origin in India, has a fruit widely known and appreciated in the North and Northeasthern Brazilian states. The Malay apple tree is extremely tall and has a long juvenile period when propagated by seed, making its vegetative multiplication is desirable, to anticipate the productive period and decrease its size, and also to obtain uniform orchards. The experiment was conducted at UNESP/FCAV, Jaboticabal Campus, using Malay apple herbaceous cuttings subjected to treatments with indol butyric acid (IBA) (0; 1,000; 3,000 and 5,000 mgL(-1)) and cuttings with and without basal incision. The variables analyzed were percentage of survival and rooting of the cuttings, number and mean length of roots per cutting. The experiment was conducted under CRB on a factorial scheme (4 X 2) with 4 replicates constituted by 10 cuttings each. Data were analyzed by Tukey's mean test at 5% probability. The vegetative propagation by rooting of herbaceous cuttings of the Malay apple is possible, however, both IBA treatments and basal incision have not shown significant effect on the analyzed variables.

Este trabalho foi conduzido para verificar o efeito do tamanho do corte, 2,5 x 2,5cm (corte 1) e 2,5 x 5,0cm (corte 2), e da temperatura de armazenamento (3, 6 e 9ºC), na velocidade da modificação da atmosfera ambiente e nas características químicas de mamões do grupo `Formosa' minimamente processados e embalados em copos plásticos (500ml). A concentração de CO2 no interior destes copos aumentou 2 a 3 vezes, durante as primeiras 6 horas após o corte, para depois diminuir e se estabilizar. Esta concentração aumentou com o aumento da temperatura de armazenamento. A umidade dos pedaços diminuiu consideravelmente nos dois primeiros dias, e a temperatura que melhor conservou a umidade foi a de 6ºC. A acidez total titulável foi menor no corte 2, com as maiores reduções a 6 e 9oC. Os teores de sólidos solúveis totais não variaram entre os tratamentos, e os cuidados higiênicos adotados durante o processamento permitiram a obtenção de produtos com baixa contagem microbiana, 10³UFC.g-1 nos pedaços armazenados a 9ºC após sete dias, e com boa manutenção da qualidade sensorial das mesmas. Estes resultados permitem indicar o mamão `Formosa' para a produção de produtos minimamente processados, na forma de pedaços, com conservação refrigerada (3 e 6ºC ) por um período de 7 dias.

Alguns aspectos clínico-cirúrgicos do criptorquismo foram investigados em 42 eqüinos. A freqüência da afecção foi elevada em cavalos Mangalarga, Quarto de Milha e sem raça definida que, em conjunto, totalizaram 73,8% dos casos. O criptorquismo abdominal (64,3%) predominou sobre o inguinal (35,7%). A retenção unilateral ocorreu na maioria dos casos (95,2%), com prevalência do criptorquismo abdominal unilateral esquerdo (45,2%). Também foi determinada a concentração da testosterona sérica em seis garanhões normais (grupo I) em plena atividade sexual (grupo-controle) e em 10 criptórquios (grupos II e III, respectivamente, cinco abdominais e cinco inguinais). A dosagem da testosterona sérica não revelou diferença (P> 0,05) entre os três grupos. Os achados indicam que a produção desse hormônio permanece inalterada no criptórquio, justificando seu comportamento sexual, semelhante ao do garanhão normal.

The pressure ulcers (PU), also known as decubitus ulcers, are defined as injuries caused by the constant pressure exerted on a particular point of the body, causing impairment of blood supply with a decrease or interruption of tissue irrigation, causing occlusion of blood vessels and capillaries, ischemia and cell death. This is a descriptive study with longitudinal design, and panel type, with quantitative approach that aimed to examine the association between predisposing conditions (PC), intrinsic factors (IF) and extrinsic factors (EF) with the occurrence of PU, in hospitalized patients in the Intensive Care Unit (ICU), pain clinical, surgical clinical and neurology wards of a university hospital. The study population was composed of all patients who were restricted to bed during the period from December 2007 to February 2008. The study was approved by the Ethics Committee of HUOL / UFRN (No 135/07). The data-collection took place through a structured formulary of observation, data from medical records and physical examination of patients skins. The results were organized in SPSS 15.0 software, tabulated, categorized and analyzed by descriptive and inferential statistics. Of the 30 patients studied, 43.3% had been hospitalized in the pain clinical and surgical clinic wards, 20.0% in the ICU, 20.0% in the ICU / ward and 16.7% in neurology, being the length of hospitalization in those units of 7 to 18 days (63.3%) and from 19 to 30 days (36.7%), predominantly female and aged ≥ 60 years (60.0%). 19 PU were diagnosed in 43.3% of patients monitored, being 38.5% with one PU between 7 to 18 days and 46.2% with two or more between 19 to 30 days of hospitalization, showing significant relationship (ρ-value = 0029) between length of hospital stay and the number of PU. Was found an association of 35.7% of the PC (cardio-respiratory, hematological, metabolic and psychogenic), IF (age group, oedema, skin changes in humidity and change of body temperature) and EF (type of mattress and strength of body pressure) for all patients studied, statistically significant (ρ-value = 0001), between the average scores in patients with and without PU, with reason chance to 12.0 for the development of PU and there was moderate correlation ( r = 0618) in the presence of this association. Results show the influence of the multiplicity of factors and conditions on the occurrence of PU, which brings us to reflect on the assistance focused on prevention and reduction of these injuries which will encourage the reduction of hospitalization length, physical and psychological suffering, and the possibility of improving the clinical condition of the patient.

O teste de envelhecimento acelerado (EA) apresenta possibilidades de uso nos programas de controle de qualidade de sementes de milho. Porém, para uso em rotina, há necessidade de padronização das condições de temperatura e período de exposição das sementes na realização do teste. Esta pesquisa teve por objetivo avaliar o efeito da combinação de duas temperaturas (42 e 45ºC) e dois períodos de envelhecimento (72 e 96h) nos resultados do teste de envelhecimento acelerado em sementes de milho. Para isso, sementes de seis genótipos de milho, tratadas e sem tratamento fungicida, com altos valores de germinação inicial, semelhantes entre si, dentro de cada genótipo, foram submetidas ao EA, de acordo com condições de temperatura e período de exposição pré-estabelecidos. Utilizou-se o delineamento experimental inteiramente casualizado com os tratamentos (lotes x germinação, antes e após o EA) dispostos em esquema fatorial, empregando-se o teste de Tukey a 5% de probabilidade na comparação das médias. Verificou-se que sementes de milho apresentam diferenças de sensibilidade ao envelhecimento acelerado, condicionadas pelo genótipo e tratamento fungicida. Contudo, a combinação 45ºC por 72h possibilita separar lotes de qualidade fisiológica superior e inferior, independentemente do genótipo. O período de exposição das sementes ao envelhecimento acelerado determina o teor de água atingido pelas mesmas.

Este trabalho teve por objetivo avaliar a qualidade de cinco híbridos de melão rendilhado, com dois e três frutos por planta, utilizando fibra da casca de coco e fertirrigação. Para tanto, foi instalado um experimento em casa de vegetação na UNESP-FCAV, Câmpus de Jaboticabal, com delineamento experimental em blocos ao acaso, em esquema fatorial 5 x 2, com quatro repetições. Os fatores avaliados foram cinco híbridos de melão rendilhado (Maxim, Bônus nº 2, Shinju 200, Fantasy e Louis) e número de frutos por planta (2 ou 3 frutos). Os frutos foram colhidos quando atingiram o máximo do desenvolvimento. Foram avaliados: sólidos solúveis, acidez titulável, pH, vitamina C e massa média dos frutos. Para todas as características avaliadas, não houve interação entre híbridos e o número de frutos por planta. Com base nos resultados obtidos, conclui-se que o híbrido Bônus nº 2 apresentou o maior número de características qualitativas desejáveis quando cultivada sob ambiente protegido, utilizando fibra da casca de coco e fertirrigação. O número de frutos por planta não afetou as características qualitativas avaliadas, exceto o teor de sólidos solúveis e massa média dos frutos, sendo maior quando deixados dois frutos por planta.

A quantitative, descriptive, cross-sectional and retrospective study, using technical procedures of document consultation from secondary sources and health household survey with application form for face to face inter views, with the assent nº.039/2011 from the Ethics Committee of the Federal University of Rio Grande do Norte. The aim of this study was to analyze the cervix cancer control in the area47 of the Health Family Centre Nova Natal II. The cancer cervix is the second most common cancer among women worldwide. In Brazil screening for early detection and treatment of disease has been poorly done and follow-up to reduce mortality has not been executed. From a total of1170women belonging to area 47, who under went screening by the Pap test in the period from 2005 to 2010,was elected a sample of 38 women with positive cervical changes, over 18 years old. The calculation of frequency analysis of socio demographic and clinical and epidemiological selected variables with the results of cervical changes, using the X2 test and taking as significance level of p<0.05 was not statistically significant. The predominant age range was 25 to 64 years (68.9%), most no white women (60.5%), predominantly with primary education (57.9%), most married (68.4%) and housewives (68.4%) with early age of sexual activity (86.8%), the minority smokers (13.2%), with a sexual partner (36.8%). At the time of interview, 42.1% of the women voiced complaint of discharge, while only 2.6% reported bleeding. In relation to the occurrence of STDs (including HPV), 10.5% of women reported being a carrier. The use of oral contraceptives was 32.3% of women, from 2 to 4 years (44.4%). The result of the last screening test performed, showed prevalence of immature squamous metaplasia (55.3%), followed by intraepithelial low- grade lesion (including the cytopathologic HPV effect and cervical intra epithelial neoplasia grade I) (31.6%); intraepithelial high-grade lesion (including cervical intraepithelial neoplasia grade II and III) (7.9%), atypical squamous non neoplastic cells (5.3%). There was no squamous cell carcinoma and adenocarcinoma. Most women received information about the action that should be done after the last screening test result (55.3%), but how to perform follow, most women did not report having done so (55.3%). The follow-up group of women studied, with varying degrees of cervical abnormalities, should only be completed with the discharge by cure, established inconsecutive negative cytology, a goal that is not being achieved in the area 47 of the Health Family Centre of Nova Natal II

The primary objective of this study was to estimate the amount of gas not emitted into the air in areas cultivated with sugarcane (Saccharum officinarum) that were mechanically harvested. Satellite images CBERS-2/CCD, from 08-13-2004, 08-14-2005, 08-15-2006 and 08-16-2007, of northwestern São Paulo State were processed using the Geographic Information System (GIS)-IDRISI 15.0. Areas of interest (the mechanically-harvested sugarcane fields) were identified and quantified based on the spectral response of the bands studied. Based on these data, the amount of gas that was not emitted was evaluated, according to the estimate equation proposed by the Intergovernmental Panel on Climate Change (IPCC). The results of 396.65 km(2) (5.91% for 2004); 447.56 km(2) (6.67% for 2005); 511.54 km(2) (7.62% in 2006); and 474.60 km(2) (7.07% for 2007), calculated from a total area of 6,710.89 km(2) with sugarcane, showed a significant increase of mechanical harvesting in the study area and a reduction of gas emissions of more than 300,000 t yr(-1).

Parent, L. E., Natale, W. and Ziadi, N. 2009. Compositional nutrient diagnosis of corn using the Mahalanobis distance as nutrient imbalance index. Can. J. Soil Sci. 89: 383-390. Compositional nutrient diagnosis (CND) provides a plant nutrient imbalance index (CND - r(2)) with assumed chi(2) distribution. The Mahalanobis distance D(2), which detects outliers in compositional data sets, also has a chi(2) distribution. The objective of this paper was to compare D(2) and CND - r(2) nutrient imbalance indexes in corn (Zea mays L.). We measured grain yield as well as N, P, K, Ca, Mg, Cu, Fe, Mn, and Zn concentrations in the ear leaf at silk stage for 210 calibration sites in the St. Lawrence Lowlands [2300-2700 corn thermal units (CTU)] as well as 30 phosphorus (2300-2700 CTU; 10 sites) and 10 nitrogen (1900-2100 CTU; one site) replicated fertilizer treatments for validation. We derived CND norms as mean, standard deviation, and the inverse covariance matrix of centred log ratios (clr) for high yielding specimens (>= 9.0 Mg grain ha(-1) at 150 g H(2)O kg(-1) moisture content) in the 2300-2700 CTU zone. Using chi(2) = 17 (P < 0.05) with nine degrees of freedom (i.e., nine nutrients) as a rejection criterion for outliers and a yield threshold of 8.6 Mg ha(-1) after Cate-Nelson partitioning between low- and high-yielders in the P validation data set, D(2) misclassified two specimens compared with nine for CND -r(2). The D(2) classification was not significantly different from a chi(2) classification (P > 0.05), but the CND - r(2) classification differed significantly from chi(2) or D(2) (P < 0.001). A threshold value for nutrient imbalance could thus be derived probabilistically for conducting D(2) diagnosis, while the CND - r(2) nutrient imbalance threshold must be calibrated using fertilizer trials. In the proposed CND - D(2) procedure, D(2) is first computed to classify the specimen as possible outlier. Thereafter, nutrient indices are ranked in their order of limitation. The D(2) norms appeared less effective in the 1900-2100 CTU zone.

In the present work, we report the use of bacterial colonies to optimize macroarray technique. The devised system is significantly cheaper than other methods available to detect large-scale differential gene expression. Recombinant Escherichia coli clones containing plasmid-encoded copies of 4,608 individual expressed sequence tag (ESTs) were robotically spotted onto nylon membranes that were incubated for 6 and 12 h to allow the bacteria to grow and, consequently, amplify the cloned ESTs. The membranes were then hybridized with a beta-lactamase gene specific probe from the recombinant plasmid and, subsequently, phosphorimaged to quantify the microbial cells. Variance analysis demonstrated that the spot hybridization signal intensity was similar for 3,954 ESTs (85.8%) after 6 h of bacterial growth. Membranes spotted with bacteria colonies grown for 12 h had 4,017 ESTs (87.2%) with comparable signal intensity but the signal to noise ratio was fivefold higher. Taken together, the results of this study indicate that it is possible to investigate large-scale gene expression using macroarrays based on bacterial colonies grown for 6 h onto membranes.

Um experimento foi realizado com leitões desmamados visando avaliar os efeitos de oito tratamentos, correspondentes à combinação dos fatores, apresentações de ração (seca e úmida), tipos de ração (sem e com edulcorante) e tipos de água de consumo (sem e com edulcorante) sobre o desenvolvimento morfológico e enzimático intestinal. Foram avaliadas a altura das vilosidades (V), a profundidade das criptas (C) e a relação altura das vilosidades e profundidade das criptas (V:C) do duodeno e do jejuno, o conteúdo de proteína na mucosa do jejuno, e as atividades enzimáticas (UA) da maltase, sacarase e dipeptidase. Utilizaram-se 32 leitões machos castrados, Large White x Landrace, desmamados aos 21 dias, submetidos aos tratamentos durante oito dias. O delineamento experimental foi em blocos casualizados, com oito tratamentos, fatorial 2 x 2 x 2, com quatro repetições. Foram observadas diferenças para a altura das vilosidades do duodeno para os grupos tratados com dieta úmida e ração com edulcorante e para a relação V:C do duodeno para os animais que receberam ração com edulcorante. Houve diferença para a UA da sacarase e da maltase para os grupos que receberam água sem edulcorante. As características histológicas foram favorecidas pelas dietas úmidas, o que pode sugerir que esta apresentação foi menos agressiva ao trato digestivo. Para os demais fatores os resultados contrariaram as expectativas de que o tratamento água com edulcorante melhoraria a qualidade do epitélio intestinal. A fase crítica pela qual os leitões foram submetidos, possivelmente, comprometeu os resultados.
