Introduction: The utility of estimates of glomerular filtration rate based on creatinine and cystatin C serum levels to assess renal function in older surgical patients remains to be determined. Objective: To determine whether 2h-creatinine clearance (CrCl-2h) can be an adequate substitute for glomerular filtration rate estimates obtained by measuring serum cystatin C and creatinine in the elderly at preoperation. Methods: A total of 102 consecutive elder patients undergoing pre-anesthesia evaluation for routine surgeries were included. Study subjects were allocated into three groups: Group 1 (G1)—hypertensive diabetic patients, Group 2 (G2)—hypertensive patients, and Group 3 (G3)—non-hypertensive and non-diabetic patients. Two-hour urine collection was performed and CrCl-2h adjusted for ultrasonic residual bladder volume was estimated. GFR was estimated based on creatinine and cystatin C serum levels. Bland-Altman analysis was used to compare methods. Results: The mean difference between the evaluated methods and CrCl-2h was <15 mL·min-1·1.73 m-2 for Cys-GFR, and >20 mL·min-1·1.73 m

Abstract: foliar anthracnose caused by colletotrichum gloeosporioides is the most important onion (allium cepae) disease in guiricema and guidoval-mg. fungicides, mostly benomyl (ben), are intensively sprayed for disease control but they have been inefficient. we tested the hypothesis of occurrence of resistant isolates of c. gloeosporioides to ben and compared fungicides for pathogen control. conidial germination of the isolates decreased as ben concentration increased and the fungicide completely prevented mycelial growth. for all pathogen isolates tested, disregarding fungicide concentration, methyl thyophanate (mt) + mancozeb (man), man, chlorothalonil (chl), ben+man, tm+clo, captan (cap), and prochloraz (pro) inhibited germination. all fungicide treatments but chl, completely halted mycelial growth. under greenhouse conditions each treatment was sprayed on onion 'texas early grano 502' (teg502) plants and the fungus was inoculated 24 h later. the most efficient treatments in reducing disease intensity were mt+man, mt+chl, ben+man, man, cap, chl, ben, and pro. ben, tm, pro or car was sprayed immediately after, or two, four, or six days after pathogen inoculation in plants of teg502. ben and pro were the most efficient when sprayed right after inoculation; no fungicide controlled the disease at the other spray times.

Abstract: The use of organic fertilizers in Brazilian agriculture has been increased recently. With the objective of evaluating the alterations in chemical properties of a typical clayey, oxisol, in Londrina, Londrina PR, Brazil, an experiment was conducted with the application of different organic residues. The following treatments were tested: bovine manure (8 T ha-1), hen manure (3 T ha-1), broiler litter (6 T ha-1), sheep manure (6 T ha-1) and silage residue (8 T ha-1). The experimental design was in randomized blocks with 6 treatments and 3 replications. Each residue was applied twice, in the beginning and 12 months after the experiment installation. Soil samplings were taken at 3, 6, 9, 12, 18, and 24 months after the application of the residues. Each sample was evaluated chemically for the following variables: pH in CaCl2, H + Al, Ca, Mg, K, P, organic matter, CEC and saturation for bases (V). In general way, the organic residues application resulted in alterations in the chemical properties of the soil. The best treatment tested was the sheep manure that promoted a larger increase of exchangeable calcium, organic matter and CEC of the studied soil. The hen manure increased the levels of soil phosphorus. Nos últimos anos, tem crescido gradualmente o emprego de adubos organicos na agricultura brasileira. Com o objetivo de avaliar as altera es nas propriedades químicas de um Latossolo Vermelho distroférrico, em fun o da aplica o de diferentes resíduos organicos, foi instalado um experimento na Fazenda Escola da Universidade Estadual de Londrina, Londrina-PR. Foram testados os seguintes tratamentos: esterco de bovino (8 T ha-1), esterco de poedeira (3 T ha-1), cama de frango (6 T ha-1), esterco de ovino (6 T ha-1) e resíduo de silagem de sorgo (8 T ha-1). O delineamento experimental utilizado foi em blocos casualizados, com 6 tratamentos e 3 repeti es. Cada resíduo foi aplicado duas vezes, no início e aos doze meses após a instala o do experimento. Amostragens de solo foram realizadas aos 3, 6, 9, 12, 18 e 24 meses após a primeira aplica o dos resíduos. As amostras foram avaliadas quimicamente para as seguintes variáveis: pH em CaCl2 , H + Al, Ca, Mg, K, P, matéria organica, CTC e satura o por bases (V). Os dados obtidos foram submetidos à análise de variancia e as médias foram comparadas pelo teste Tukey a 1 e 5%. A aplica o dos resíduos organicos resultou em altera es das propriedades químicas e na fertilidade do solo. Para as doses testadas, destacouse o tratamento esterco de ovino, que promoveu os maiores aumentos para cálcio trocável, matéria or

Abstract: The search for forage alternatives in dry season that are economically viable has taken many livestock farmers to use the sugar cane in the ruminants feeding. This bibliographical review was realized with the objective to discuss the sugar cane nutritional characteristics and its utilization in ruminants feeding. Positive and negative aspects had been told as the production potential, the growing easiness and nutritional limitations. Information had been approached as chemical composition, by-product uses and possible treatments, such as the chemical treatment that increases its digestibility and intake, improving the animals performance. The results of different researches suggest some ways of sugar cane use for the satisfactory results obtaining. However, considering that the sugar cane is poor in proteins and mineral elements, there is necessity of protein supplementation to supply the nutritional requirements. A busca por alternativas de volumosos na época da esta o seca, que sejam economicamente viáveis, tem levado muitos pecuaristas a utilizarem a cana-de-a úcar na alimenta o de ruminantes. Esta revis o bibliográfica foi realizada com o objetivo de discutir as características nutricionais da cana-de-a úcar e suas formas de utiliza o na alimenta o de ruminantes. Foram relatados os aspectos positivos e negativos como o potencial de produ o, facilidade de cultivo e as limita es nutricionais. Abordaram-se informa es como composi o química, utiliza o de subprodutos e possíveis tratamentos, tal como, o tratamento químico que aumenta a sua digestibilidade e consumo, melhorando o desempenho dos animais. Os resultados de diferentes trabalhos de pesquisa sugerem várias formas de utiliza o da cana-de-a úcar para a obten o de resultados satisfatórios. Entretanto, considerando que este é um alimento pobre em proteínas e minerais há necessidade de suplementa o destes componentes para suprir as exigências nutricionais das diferentes categorias animais.

Abstract: A antracnose foliar causada por Colletotrichum gloeosporioides é a doen a mais importante da cebolicultura (Allium cepae) em Guidoval e Guiricema, MG. Para controle da doen a, utilizam-se intensivamente fungicidas, principalmente benomil (Ben), o que tem sido pouco efetivo. Neste trabalho, testou-se a hipótese da existência de isolados de C. gloeosporioides resistentes ao Ben e se comparou a eficiência de diferentes fungicidas no controle do patógeno. Nas concentra es testadas, Ben impediu o crescimento micelial do fungo, e a germina o de conídios decresceu com o aumento da concentra o do produto. Independente do isolado do patógeno e da concentra o dos fungicidas, ocorreu maior inibi o da germina o com Tiofanato metílico (Tm) + Mancozeb (Man), Man, Clorotalonil (Clo), Ben+Man, TM+Clo, Captan (Cap) e Procloraz (Pro). Excetuando-se Clo, os demais tratamentos inibiram totalmente o crescimento micelial do fungo. Em casa de vegeta o, pulverizaram-se os diferentes tratamentos em plantas de cebola 'Texas Early Grano 502' (TEG502) e 24 h após inoculou-se o patógeno. Maior redu o na intensidade da doen a ocorreu com TM+Man, TM+Clo, Ben+Man, Man, Cap, Clo, Ben e Pro. Em plantas de TEG502, pulverizaram-se diferentes fungicidas imediatamente após, dois, quatro ou seis dias após inocula o do patógeno. Na pulveriza o imediatamente após a inocula o, Ben e Pro foram os mais eficientes; nas demais épocas, nenhum fungicida reduziu a severidade da doen a.

Abstract: the capacity of two bacteria isolated from the tomato phylloplane to control late blight (phytophthora infestans) was investigated in the field, and compared against the effectiveness of spraying with the fungicide chlorothalonil (1.5 g a.i. l-1) or water (control). a 55% reduction in late blight intensity was observed in the leaves of the middle of the plant and 62% in those of the upper leaves when using the antagonist ufv-stb 6 (novosphingobium capsulatum) as compared to the control. isolate ufv-iea 6 (bacillus cereus) was able to reduce disease intensity by 55%, but only in the upper leaves of the tomato plants. treatment with isolate ufv-stb 6 also led to a significant reduction in the percentage of fruits with late blight symptoms. the results demonstrate the potential of these two bacteria in controlling this disease.

Abstract: despite the importance of onion (allium cepa) leaf anthracnose caused by colletotrichum gloeosporioides in latin america, africa, and asia, few studies have focused on host resistance to the pathogen. therefore, in this study, resistance components of two cultivars and eight accessions of onion to four isolates of c. gloeosporioides were evaluated under greenhouse conditions. inoculations were performed either by spraying inoculum suspension or by placing a mycelial disc on the leaf. the cultivars and accessions differed significantly regarding initial infection frequency and monocyclic progress rate (rg) with the spray-inoculation, and regarding incubation period and lesion area with the mycelial-disc inoculation. correlation coefficient (r) values were estimated between the components with the mycelial disk inoculations. values of r were 0.98 between disease severity visually assessed nine days after inoculation (sev9) and area under the disease progress curve (audpc), 0.80 between sev9 and disease severity assessed with the leaf area meter (sev), 0.72 between sev9 and rg, 0.64 between sev9 and infection frequency nine days after inoculation, 0.81 between sev and audpc, and 0.64 between sev and rg. considering both the significant r values associated with sev9 and that to estimate sev9 there is no need of rating diagrams, this component is potentially useful to evaluate onion germplasm against c. gloeosporiodes. the spray inoculation procedure was faster, simpler, and provided higher infection efficiency and lower variability than the mycelial disk inoculation technique. therefore, this should be the preferred inoculation procedure when assessing onion germplasm.
