The main goal of this study was to evaluate the effects of different levels of irrigation water and nitrogenon yield, quality, and water productivity of processing tomato grown in clay-loam soil. Three water levels of panevaporation (Epan) replenishment applied via drip irrigation (1.00 × Epan, 0.75 × Epan, and 0.50 × Epan) and four Napplication rates with fertigation (0, 60, 120, and 180 kg N·ha-1) were tested in the sub-humid climate conditions ofTurkey during the 2010 and 2011 growing seasons. The highest marketable yields were observed with full irrigation(1.00 × Epan) for each season. Decreasing irrigation rate generally improved dry matter, total soluble solids, totalsugars, titratable acidity, lycopene and total carotene, and decreased fruit NO3-N content and fruit total proteincontent slightly. The highest water productivity was obtained with a moderate soil water deficit (0.75 × Epan). The 180kg N·ha-1 fertilization rate produced the highest values for marketable yield, fruit size, total soluble solids yield, NO3-N,and total protein content. Increasing N rate also increased the values of fruit total sugars and titratable acidity. Increasing both irrigation and N levels increased the NO3-N and protein contents. The higher lycopene and totalcarotene values were obtained in the treatments of 60 and 120 kg N·ha-1. Increasing N supply improved the waterproductivity with the 3 irrigation application ratios. Considering the quantity and quality for the processing and waterproductivity, the 0.75 × Epan irrigation regime and a 120 or 180 kg·ha-1 nitrogen supply can considered optimal.

Lesions in the thymus and bone marrow in chicks with experimentally induced chicken infectious anemia disease

Burak Kuscu,Aydin Gurel 대한수의학회 2008 JOURNAL OF VETERINARY SCIENCE Vol.9 No.1

One-day-old SPF chicks were inoculated with the Cux-l strain of chicken infectious anemia virus (CIAV), and the clinical development of disease and its macroscopic and microscopic alterations in the thymus and bone marrow, were observed. Tissue sections of thymus and bone marrow were stained using the streptavidin-biotin peroxidase method and examined under light microscope for evaluation of antigenic intensities in tissues. Those findings were then compared with blood parameters and ELISA results obtained through collected sera during sacrifice procedures. We sought to determine: the localization of viral antigens in thymus and bone marrow tissues after inoculation, the correlation between antigen intensities and hematologic, serologic and histopathologic findings, definitive diagnostic criteria using histopathologic and immunoperoxidase methods, and the reliability of these methods in the diagnosis of CIAV infection. For this purpose, 83, one-day-old SPF chicks were used. The birds were divided into experimental (n = 52) and control (n = 26) groups. A virus dose of TCID50 of 100,000/ml was administered intramuscularly to every bird in the experimental group. Based on the results of this study, we have suggested that clinical examination, along with macroscopic and microscopic evaluation of the thymus and bone marrow, maybe undertaken starting from day 7 post-inoculation (PI). ELISA, might be of value, as it might give consistent results starting from day 14 PI. However, the most reliable results were obtained through examination of thymus and bone marrow sections from infected birds stained by immunoperoxidase technique, as early as day 4 PI.

The objective of this study was to examine the effects of grafting and kinds of rootstocks on yield that are economically feasible for the watermelon producer. Fruit characteristics and quality attributes of grafted plants in open field conditions were also analyzed. The tongue approach grafting method was adopted. Three Watermelon cultivars of ‘Crimson Tide’, ‘Dumara’, and ‘Farao’ were used as the scion. Three hybrid squashes of ‘Dynamo’, ‘RS-841’, and ‘Shintosa’ were used as rootstocks. Results showed that some fruit quality indicators such as dry matter, total soluble solids, total sugar and titratable acid contents were lower in grafted plants while lycopene contents remained unchanged. The pH was slightly altered by grafting. Use of rootstock did not show advantages at comparable fruit quality indicators. Results also showed that fruit shape index, rind thickness, fruit weight, total yield and marketable yield were significantly influenced by grafting. Use of rootstocks significantly increased previously mentioned values which is related with yield,as compared to the non-grafted plant. Analyses proved the use of rootstocks as economically feasible and an advantageous alternative in watermelon production.

Transobturator Tape Operation Is More Effective in Premenopausal Women than in Postmenopausal Women with Stress Incontinence

Purpose: Midurethral synthetic slings for female stress urinary incontinence are minimally invasive polypropylene mesh tapes that are inserted under the midurethra with trocars. In the past decade, this new technology has become the most commonly performed procedure for female stress urinary incontinence, replacing the traditional open procedures. However, its effectiveness in pre- and postmenopausal women has not previously been compared. Materials and Methods: We assessed the clinical outcome of the transobturator tape (TOT) procedure in premenopausal (n=45) and postmenopausal (n=49) women by means of self-report and the Urinary Distress Inventory 6 (UDI-6) questionnaire. Results: The mean age of the pre- and postmenopausal women was 44 and 60 years, respectively. Mean parity was 2.4 and 3, respectively. There were no significant differences with respect to mean operation time, duration of hospitalization, or intraoperative and postoperative complications. However, premenopausal women were more satisfied with the operation than were postmenopausal women (p=0.014). Also, UDI-6 scores were significantly better in premenopausal women (p=0.027). Conclusions: The TOT operation appeared to be more effective in premenopausal women with stress urinary incontinence. However, further studies with larger sample sizes are needed to confirm our results.
