    A virus causing a disease in mint (the aromatic and culinary plant) has recently become a problem in the Taurus Mountains, a mountain range in the Mediterranean region of Turkey. To detect the virus and investigate its distribution in the region, mint leaf samples were collected from the vicinity of spring areas in the plateaus of Antalya and Konya in 2009. It was found that Cucumber mosaic virus (CMV) was detected in 27.08% of symptomatic samples tested by DAS-ELISA. To the best of our knowledge, this is the first report of CMV on mint plants in this region of Turkey

    Sugar beet plants (cv. Arosa), susceptible to rhizomania, were grown in 144 soil samples taken from sugar beet fields in north and central part of Turkey in 2004. Incidences of Beet necrotic yellow vein virus (BNYVV) and Beet soilborne virus (BSBV) by ELISA and of their vector Polymyxa betae by root staining method were determined in bait plants. Some soil properties such as, texture, pH, organic matter, cation exchange capacity, electrical conductivity, lime (CaCO3) and exchangeable Ca, Mg, K and Na contents were determined. Sand content and pH values of the soils gave significant positive correlations with P. betae (0.177* and 0.164*, respectively). Lime (CaCO3) and exchangeable Mg contents had also significant positive correlations with soil pH. Increasing CaCO3 (0.189*) and exc. Mg (0.235**) content of soils induced BNYVV and BSBV infections respectively, transmitted by P. betae, due to their increasing effects on soil pH.Se cultivaron plantas de remolacha azucarera (cv. Arosa), susceptibles a rhizomania, en 144 muestras de suelo recogidas de campos del norte y centro de Turquía en 2004. Se determinó la incidencia de Beet necrotic yellow vein virus (BNYVV) y Beet soilborne virus (BSBV) por ELISA y de su vector Polymyxa betae por el método de tinción de raíz en plantas cebo. Se determinaron algunas propiedades del suelo tales como textura, pH, materia orgánica, capacidad de intercambio catiónico, conductividad eléctrica, y contenidos en cal (CaCO3), y Ca, Mg, K y Na intercambiables. El contenido en arena y los valores de pH de los suelos presentaron correlaciones positivas con P. betae (0,177* y 0,164*, respectivamente). La cal (CaCO3) y el contenido en Mg intercambiable estuvieron también positivamente correlacionados con el pH del suelo. Contenidos crecientes en CaCO3 (0,189*) y en Mg intercambiable (0,235**) de los suelos indujeron infecciones de BNYVV y BSBV respectivamente, transmitidas por el vector P. betae, debido a su creciente efecto en el pH del suelo

    A survey was carried out to detect Beet necrotic yellow vein virus (BNYVV) in soil samples using RT-PCR and bait plant techniques from the sugar beet production area of Tokat, Turkey in 2001. More than 80% of the soil samples analyzed were found to be contaminated with the virus. The partial nucleotide sequence of cDNA corresponding to RNA-3 of BNYVV isolates were analyzed for six different regions of Tokat province. All isolates were assigned to type A strains based on RFLP analysis and DNA sequences. Sequence comparison revealed differences at amino acid positions 35, 68, 71 and 179 of the P25 coding region amongst Turkish isolates. Additionally, all Turkish isolates were compared with Japanese, French, Kazakh, Italian and Belgian isolates

    Forestry is an important subject because it supplies wood and timber for direct human consumption, in addition to its positive effects on global warming and on bio-diversity, with a history dating back to antiquity. As a labor-intensive sector in developing countries, it maintains interactions with natural resources management, public relations and socio-economic structure. It can affect the prosperity of countries either positively or negatively. Hence, an analysis of the history of forestry bears importance because it not only sheds light on its past and present condition, but also explains the improvements for the protection of forests. Accordingly, in the first section of this study, general information on the Ottoman Land System and Ottoman Forestry Organization will be given. In the second section, we will treat 19th century westernization movements, as well as socio-cultural and economic changes. The third section will include significant regulations on forestry, forest management, and administration in the Ottoman Empire; as well as the influence of Ottoman forestry on the actual socio-economic structure. In the final section, under the title discussion and conclusion, Ottoman forestry will be examined regarding its consequences in terms of policy, economy and law.<br>A silvicultura é um assunto importante, pois o suprimento de madeira em geral e madeira para consumo humano direto, além de seus efeitos positivos sobre o aquecimento global e sobre a diversidade biológica, trata de uma história que remonta à antiguidade. Como um setor de trabalho intensivo nos países em desenvolvimento, mantém interações com a gestão dos recursos naturais, relações públicas e estrutura socioeconômica. Ela pode afetar a prosperidade dos países, seja positiva ou negativamente. Assim, uma análise da história da silvicultura tem importância, porque não só lança luz sobre a sua condição passada e presente, mas também explica as melhorias para a proteção das florestas. Assim, na primeira parte deste estudo, serão dadas informações gerais sobre o Sistema de Terras e Florestas e Organização Otomano. Na segunda seção, serão tratados movimentos da ocidentalização do século 19, bem como alterações socioculturais e econômicas. A terceira seção irá incluir regulamentos significativos na silvicultura, manejo florestal e administração no Império Otomano, bem como a influência da silvicultura Otomano na atual estrutura socioeconômica. Na seção final, no âmbito da discussão do título e conclusão, a silvicultura Otomano será analisada em relação as suas consequências em termos de economia, política e direito

    Background: Ileus is common after elective colorectal surgery, and is associated with increased adverse events and prolonged hospital stay. The aim was to assess the role of non-steroidal anti-inflammatory drugs (NSAIDs) for reducing ileus after surgery. Methods: A prospective multicentre cohort study was delivered by an international, student- and trainee-led collaborative group. Adult patients undergoing elective colorectal resection between January and April 2018 were included. The primary outcome was time to gastrointestinal recovery, measured using a composite measure of bowel function and tolerance to oral intake. The impact of NSAIDs was explored using Cox regression analyses, including the results of a centre-specific survey of compliance to enhanced recovery principles. Secondary safety outcomes included anastomotic leak rate and acute kidney injury. Results: A total of 4164 patients were included, with a median age of 68 (i.q.r. 57\u201375) years (54\ub79 per cent men). Some 1153 (27\ub77 per cent) received NSAIDs on postoperative days 1\u20133, of whom 1061 (92\ub70 per cent) received non-selective cyclo-oxygenase inhibitors. After adjustment for baseline differences, the mean time to gastrointestinal recovery did not differ significantly between patients who received NSAIDs and those who did not (4\ub76 versus 4\ub78 days; hazard ratio 1\ub704, 95 per cent c.i. 0\ub796 to 1\ub712; P = 0\ub7360). There were no significant differences in anastomotic leak rate (5\ub74 versus 4\ub76 per cent; P = 0\ub7349) or acute kidney injury (14\ub73 versus 13\ub78 per cent; P = 0\ub7666) between the groups. Significantly fewer patients receiving NSAIDs required strong opioid analgesia (35\ub73 versus 56\ub77 per cent; P &lt; 0\ub7001). Conclusion: NSAIDs did not reduce the time for gastrointestinal recovery after colorectal surgery, but they were safe and associated with reduced postoperative opioid requirement

    Background: Ileus is common after colorectal surgery and is associated with an increased risk of postoperative complications. Identifying features of normal bowel recovery and the appropriateness for hospital discharge is challenging. This study explored the safety of hospital discharge before the return of bowel function.Methods: A prospective, multicentre cohort study was undertaken across an international collaborative network. Adult patients undergoing elective colorectal resection between January and April 2018 were included. The main outcome of interest was readmission to hospital within 30 days of surgery. The impact of discharge timing according to the return of bowel function was explored using multivariable regression analysis. Other outcomes were postoperative complications within 30 days of surgery, measured using the Clavien-Dindo classification system.Results: A total of 3288 patients were included in the analysis, of whom 301 (9.2 per cent) were discharged before the return of bowel function. The median duration of hospital stay for patients discharged before and after return of bowel function was 5 (i.q.r. 4-7) and 7 (6-8) days respectively (P &lt; 0.001). There were no significant differences in rates of readmission between these groups (6.6 versus 8.0 per cent; P = 0.499), and this remained the case after multivariable adjustment for baseline differences (odds ratio 0.90, 95 per cent c.i. 0.55 to 1.46; P = 0.659). Rates of postoperative complications were also similar in those discharged before versus after return of bowel function (minor: 34.7 versus 39.5 per cent; major 3.3 versus 3.4 per cent; P = 0.110).Conclusion: Discharge before return of bowel function after elective colorectal surgery appears to be safe in appropriately selected patients

    No full text
    Aim: Aspiration is a common cause of pneumonia in patients with postoperative ileus. Insertion of a nasogastric tube (NGT) is often performed, but this can be distressing. The aim of this study was to determine whether the timing of NGT insertion after surgery (before versus after vomiting) was associated with reduced rates of pneumonia in patients undergoing elective colorectal surgery. Method: This was a preplanned secondary analysis of a multicentre, prospective cohort study. Patients undergoing elective colorectal surgery between January 2018 and April 2018 were eligible. Those receiving a NGT were divided into three groups, based on the timing of the insertion: routine NGT (inserted at the time of surgery), prophylactic NGT (inserted after surgery but before vomiting) and reactive NGT (inserted after surgery and after vomiting). The primary outcome was the development of pneumonia within 30&nbsp;days of surgery, which was compared between the prophylactic and reactive NGT groups using multivariable regression analysis. Results: A total of 4715 patients were included in the analysis and 1536 (32.6%) received a NGT. These were classified as routine in 926 (60.3%), reactive in 461 (30.0%) and prophylactic in 149 (9.7%). Two hundred patients (4.2%) developed pneumonia (no NGT 2.7%; routine NGT 5.2%; reactive NGT 10.6%; prophylactic NGT 11.4%). After adjustment for confounding factors, no significant difference in pneumonia rates was detected between the prophylactic and reactive NGT groups (odds ratio 1.03, 95% CI 0.56\u20131.87, P&nbsp;=&nbsp;0.932). Conclusion: In patients who required the insertion of a NGT after surgery, prophylactic insertion was not associated with fewer cases of pneumonia within 30&nbsp;days of surgery compared with reactive insertion
