In this context, the clinical distinction between Wnt and SHH groups are realized by considering the age, gender, survival time, location of the lesion, and radiological features of the patients.MATERIAL and METHODS: Molecular separation was performed by RT-PCR analysis of CTNNB1, AXIN, PTCH1, SMO, SUFU, and GLI1 mRNA expression changes.RESULTS: About 17.8% and 22.2% of the cases were included in the Wnt and the SHH group, respectively. When comparing group differences based on clinical and molecular data, 72.7% and 66.6% of matches were observed in the Wnt and the SHH group, respectively.CONCLUSION: It has been revealed that molecular analysis and grouping of patients with medulloblastoma can provide support for clinically determined subgroups.Publication Statistical shape analyses of the brainstem in chiari patients(Türk Nöroloji Derneği, 2021-01-01) Ocakoglu, Gokhan; OCAKOĞLU, GÖKHAN; Taskapilioglu, Mevlut Ozgur; TAŞKAPILIOĞLU, MEVLÜT ÖZGÜR; Altunyuva, Oguz; ALTUNYUVA, OĞUZ; Yilmazlar, Selcuk; YILMAZLAR, SELÇUK; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi Biyoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Nöroşirürji Anabilim Dalı.; 0000-0002-1114-6051; 0000-0001-5472-9065; 0000-0002-3450-0471; AAH-5180-2021; AAK-9899-2020AIM: To ascertain whether the brain stem's shape differs in patients with syrinx and without syrinx in cases with Chiari malformation Type I (CM-1), relative to healthy controls.MATERIAL and METHODS: Data on marked brainstem regions were obtained from 2D digital image files. Generalized Procrustes analysis was used to evaluate shape differences among patients with syrinx, patients without syrinx, and healthy controls. Shape deformations among groups were examined by Thin Plate Spline (TPS) analysis.RESULTS: According to the brain stem shape, there were differences between patients with syrinx and controls, and between patients without syrinx and controls. High-level deformations were also observed among the groups.CONCLUSION: In the present study, the presence of shape deformations in Chiari patients' brainstem was demonstrated. This is the first study using a landmark-based geometrical morphometric method to demonstrate the shape difference in Chiari patients' brainstem.
