    The Effects of Glomus Intraradices on Seedling Growth Parameters of Sage (Salvia Officinalis L.) Under Salinity Stress Conditions
    (Association of Agricultural Technology in Southeast Asia, 2024) Tunçtürk, R.; Tunçtürk, M.; Danesh, R.Y.; Najafi, S.; Toprak, T.
    Salinity is a significant abiotic stress that adversely affects plant growth and development, threatening global agricultural productivity, particularly in arid and semi-arid regions. Results indicated that increasing salt concentrations significantly inhibited seedling growth in all studied parameters, with control plants (0 mM) exhibiting the highest growth values. The tallest plants measured 23.16 cm in the control treatment, while those exposed to 200 mM salt reached only 13.12 cm. Although AMF applications did not show significant effects on plant height, they positively influenced growth parameters in salt-free conditions. Statistical analysis revealed significant interactions between salt levels and AMF on root fresh and dry weights, with the highest values recorded in the control group. Furthermore, AMF applications generally promoted growth, particularly in non-saline conditions, corroborating findings from previous research highlighting mycorrhizae's role in enhancing plant stress tolerance. In conclusion, the research findings emphasize the detrimental impact of salinity on plant development and the potential of mycorrhizal inoculation as a strategy to mitigate these effects. These findings contribute to understanding the beneficial role of AMF in improving salt tolerance and promoting sustainable agricultural practices in saline-prone environments. © 2024 Association of Agricultural Technology in Southeast Asia.

    How Does Puncture Modality Affect the Risk of Intraoperative Bleeding During Percutaneous Nephrolithotomy? a Prospective Randomized Trial
    (Elsevier Ltd, 2021) Sahan, A.; Cubuk, A.; Ozkaptan, O.; Ertas, K.; Toprak, T.; Eryildirim, B.; Sarica, K.
    Introduction and objectives: To evaluate the possible effects of two different renal puncture techniques (ultrasound-assisted [US-assisted], fluoroscopic-guided [FG]) on the intraoperative hemorrhage risk during percutaneous nephrolithotomy (PCNL). Material and methods: A total of 130 patients with Guy stone scores of 1-2 were prospectively allocated to US-assisted and FG puncture groups by simple randomization. Patients with intraoperative pelvicalyceal rupture and the ones requiring multiple accesses were excluded from the study. Apart from the puncture steps, all other steps of the PCNL procedure were performed with similar techniques by a single surgeon. Patient characteristics, operative data, and postoperative outcomes were compared. Results: A total of 10 patients were excluded from the study due to intraoperative complications after puncture. Patient demographics and stone characteristics were similar between the two groups (P > .05). Mean hemoglobin drop was meaningfully greater in the FG group (1.7 g/dL) when compared with US-assisted group (1.3 g/dL) (P < .01). The mean duration of radiation exposure was significantly higher for the FG (P < .001). Total operative time, number of attempts for a successful puncture, length of hospital stay, and stone free rates were similar between the groups (P > .05). In addition, the remaining complications classified according to the modified Clavien-Dindo grading system were similar between groups (P > .05). Conclusion: US-assisted puncture provides significantly decreased level of hemoglobin drop and radiation exposure time when compared with FG. © 2021 AEU
