Abstract Salmonella Enteritidis is the major cause of foodborne salmonellosis affecting human health. The light emitting diodes (LEDs) is a novel approach to inactivate of the foodborne pathogens. The aim of this study was to determine the antibacterial effect of 405 nm LEDs illumination on S. Enteritidis and S. Enteritidis PT4. The irradiance of the 405 nm LEDs was 27.7 mW/cm2. Bacterial cultures suspended in tryptic soy broth were illuminated by 10-watt LEDs at a distance of 4.5 cm for 24 hours at 4 °C, 25 °C and 37 °C. Approximately 7-log reduction in colony forming unit (CFU) counts of both S. Enteritidis and S. Enteritidis PT4 at each temperature were observed following exposure after 7.5 hours to the LEDs, concluding that temperature did not affect the inactivation of the bacteria. The decimal reduction times (D-values) for the serotypes ranged from 55.78 to 67.88 min at 4, 25 and 37 °C after 405 nm LEDs illumination. No significant difference in D-values was observed among both the serotypes and temperatures, except for S. Enteritidis which had lower D-value at 4 °C. The LEDs technology has shown antibacterial efficacy and can be implemented in the food processing for reducing S. Enteritidis.

ABSTRACT Objectives: To evaluate national practice patterns in the treatment of male anterior urethral strictures among Turkish urologists. Materials and Methods: A survey form including 12 questions prepared to determine active Turkish urologists' approach to diagnosis and treatment of the adult urethral stricture (US) were filled out. Based on the survey results, the institutions which 218 urologists work and their years of expertise, methods they used for diagnosis and treatment, whether or not they perform open urethroplasty and timing of open urethroplasty were investigated. Results: Optic internal urethrotomy and dilatation are the most commonly used minimal invasive procedures in treatment of US with the ratios of 93.5% and 63.3% respectively. On the other hand it was seen that urethroplasty was a less commonly used procedure, compared to minimal invasive techniques, with the ratio of 36.7%. Survey results showed us that the number of US cases observed and open urethroplasty procedures performed increases with increasing years of professional experience. Conclusions: As a method demanding special surgical experience and known as a time-consuming and challenging procedure, open urethroplasty will be able to take a greater part in current urological practice with the help of theoretical education and practical courses given by specific centers and experienced authors.

RESUMO Neste estudo, algumas das propriedades físicas e anatômicas de madeira afetada pelo cancro do castanheiro (CBD) foram investigadas, e o estudo também incluiu observações usando espectroscopia Raman. O objetivo destas investigações foi determinar a dimensão do dano que é causado na madeira dos castanheiros doentes, que devem ser removidos da floresta e utilizados na fabricação de produtos industriais. Foi avaliado que a maioria dos efeitos adversos da doença esta localizado no câmbio vascular. Há uma clara indicação de deterioração da madeira no último anel de crescimento junto ao câmbio vascular. Na região doente do xilema secundário ao lado do câmbio vascular o diâmetro, frequência e comprimento do vaso eram menores, e os vasos e outras células eram irregulares comparados à madeira saudável. Esporos foram detectados e identificados como Cryphonectria parasitica (Murrill). Propriedades dos anéis anuais (largura de anéis de crescimento anual, porcentagem de lenho tardio, etc.) foram similares em madeira doente e madeira saudável. O resultado da espectroscopia Raman não mostrou mudança significativa na estrutura da parede celular ou dos seus componentes. Depois de retirar as partes doentes, o uso ilimitado da madeira é possível. Tratamento térmico da madeira é sugerido antes da utilização para fins de saneamento e estabilidade dimensional.

ABSTRACT In this study, some of the physical and anatomical properties of Chestnut Blight Diseased (CBD) wood were investigated, and the study also included observations using Raman spectroscopy. The objective of these investigations was to determine the extent of the damage that is done to the wood of the diseased chestnut trees, which must be removed from the forest and used in the manufacture of industrial products. It was indicated that most of the adverse effects of the disease were in the vascular cambium. There was a clear indication of deterioration of the wood in the last growth ring next to vascular cambium. In the diseased secondary xylem region next to vascular cambium; vessel diameter, vessel frequency and vessel element length had a decrease, and vessel and other cells were irregular compared to healthy wood. Spores were detected and identified as Cryphonectria parasitica (Murrill). Annual ring properties (annual growth ring width, latewood percentage, etc.) were similar in diseased wood compared to healthy wood. The Raman spectroscopy results showed no significant changes in the structure of the cell wall or its components. After removing the diseased parts, unlimited usage of formerly wood is possible. Heat treatment of the wood is suggested before use in the interest of sanitation and dimensional stability.

La sarcoidosis, un trastorno multiorgánico de etiología desconocida que afecta varios órganos, es poco frecuente en los niños. Se desconocen la incidencia y la prevalencia reales de la sarcoidosis infantil. Al igual que en los adultos, muchos niños con sarcoidosis tal vez no presentan síntomas y la enfermedad cursa sin diagnosticarse. Es fundamental realizar una evaluación completa y sistemática del paciente para establecer el diagnóstico de sarcoidosis en los niños. Se describe el caso de una nina de 12 años con uveítis y hepatoesplenomegalia de dos años de evolución. Mediante una tomografía computarizada del tórax, se hallaron nódulos pulmonares periféricos dispersos y linfadenopatía hiliar bilateral. La aspiración de médula ósea y la biopsia de hígado no fueron diagnósticas. La biopsia de pulmón mostró granulomas de células epitelioides no necrosantes. A la paciente se le diagnosticó sarcoidosis en virtud del hallazgo de inflamación granulomatosa y de la exclusión de entidades confusoras.

Purpose Technological developments provide a lot of conveniences to our lives. This issue is one of the risks that arise along with these conveniences. In our study we tried to understand the impact of electromagnetic waves from mobile phones on bladder tissue. Materials and Methods Twenty-one adult male albino rats were divided into three equal groups. Group 1 was exposed to electromagnetic wave for 8 hours per day for 20 days and then their bladders were taken off immediately. Group 2 was firstly exposed to electromagnetic wave for 8 hours per day for 20 days then secondly another for 20 days without exposition to electromagnetic wave and then their bladders were taken off. Group 3 was the control group and they were not exposed to electromagnetic wave. Results Under microscopic examination of bladder tissue, in the first group severe inflammatory cell infiltration was seen in lamina propria and muscle layer in contrast to intact urothelium. In the second group mild inflammatory cell infiltration was seen in lamina propria and muscle layer. The mean scores for the three groups were 5.5 ± 2.5, 0.8 ± 1.3 and 1.2 ± 1.5 respectively. Mean score of group 1 was statistically higher than others (p = 0.001). Conclusion Intensive use of mobile phones has negative impact on bladder tissue as well as the other organs. Keeping a minimum level of mobile phone use makes it easy to be kept under control of diseases in which inflammation is an etiologic factor.

OBJECTIVE: To compare the surgical outcomes of stapled and handsewn closures in loop ileostomies. METHODS: The data of 225 patients requiring loop ileostomies from 2002 to 2007 were retrospectively evaluated. The patients underwent partial small-bowel resections and either handsewn or stapled anastomoses for the ileostomy closures. They were followed up postoperatively with routine surgical examinations. RESULTS: The study group consisted of 124 men and 101 women with a mean age of 49.12 years. The ileostomy closure was performed with handsewn in 129 patients and with stapled in 96 patients. The mean time to the first postoperative flatus was 2.426 days in the handsewn group and 2.052 days in the stapled group (p <0.05). The mean time to the first postoperative defecation was 3.202 days in the handsewn group and 2.667 days in the stapled group (p <0.05). The mean duration of patient hospital stay was 8.581 days for the handsewn group and 6.063 days for the stapled group (p <0.05). CONCLUSIONS: Patients who underwent ileostomy closure with stapled recovered faster in the postoperative period and required shorter hospital stays than those whose closures were performed with handsewn. In our opinion, stapled should be considered the gold standard for loop ileostomy closures
