... Several authors have reported nearly identical results, indicating that MS plays a significant role in the development of BTN [5,8,12,25]. Multiple studies [7,13,20,29] indicate that patients with secondary TN due to MS have a lower average onset age, are more prone to developing drug resistance, and thus require surgical treatment at an earlier stage. In comparison to TN patients from other causes, those with secondary TN associated with MS show no difference in early treatment outcomes and complications following percutaneous rhizotomy. ...

[7][8][9] To the best of our knowledge, there has been no report in the literature regarding the clinical significance of combined tibial SEP and urodynamics in predicting the neurourological abnormality and follow-up in children with neurogenic bladder. Thus this present study aimed to investigate the relation between tibial SEP results and urodynamics to use those tests together to predict the location of neural injury along with the nervous system and to follow-up on any new neural damage in the future. ...

... In the literature, in neural tube development studies based on the chick embryo model, TAA/NA ratio and AgNOR numbers were used as a measure of the proliferation activity of cells and were measured to be low in cells with growth retardation (Ertekin et al., 2021;Rakip et al., 2021 showed neural tube defect formation (Ertekin et al., 2019;Rakip et al., 2021). Also, the effects of different drugs such as caffeine, methotrexate, quetiapine on neural tube development were investigated with the chick embryo model Ovalioglu et al., 2021;Vatansever et al., 2003). This shows the possibility of similar results with different chemicals depending on the chemical and physical effects of sugammadex as well as its pharmadynamic effect. ...

... Несмотря на то, что содержание тартразина в продуктах регламентируется нормативно-правовыми актами, остаются вопросы о безопасности его использования для здоровья человека. Имеются сведения о генотоксическом и тератогенном действиях тартразина [2,3], его способности вызывать аллергические реакции (астма, сыпь) [4], изменения поведения у детей (гиперактивность в сочетании с дефицитом внимания), а также морфологии и биохимических маркеров почек и печени, головного мозга [5,6]. ...

... In some patients complete excision is curative, while in others symptomatic recurrence occurs despite GTR. [6][7][8][9][10][11][12] Outcome predictors have included extent of resection, 6,10 en bloc versus piecemeal resection, 13 early detection and thus smaller tumor size at the time of surgery, 7 distance of the tumor from the conus medullaris, 8 involvement of the sacral spinal levels, 9 unclear boundaries, bony erosions, adjuvant radiation therapy (RT) regardless of extent of resection, and the occurrence of any surgical complications. 14,15 Despite these known prognostic factors, the long-term outcome of MPE treatment remains difficult to predict in individual cases. ...
