Phantoms containing Fe3+ demonstrated detectable changes in T2* and QSM relaxation times relative to Fe2+ phantoms. Compared to pre-P-AscH-, GBM T2* and QSM imaging were significantly changed post-P-AscH- infusion consistent with conversion of Fe3+ to Fe2+. No significant changes in T2* or QSM were observed in normal brain tissue. There was moderate concordance between T2* and QSM changes in both progression free survival and overall survival. The GBM mouse model showed similar results with P-AscH- inducing greater changes in tumor labile iron pools compared to the normal tissue. CONCLUSIONS T2* and QSM MR-imaging responses are consistent with P-AscH- reducing Fe3+ to Fe2+, selectively in GBM tumor volumes and represent a potential biomarker of response. This study is the first application using MR imaging in humans to measure P-AscH--induced changes in redox-active iron. The relation between migraine and vascular risk factors is an unclear issue. Furthermore, the reasons for chronification are still unknown. Probably, the age-related risk and other factors leading to migraine progression will also change in the future. Under these questions, we aimed to investigate whether or not there is a specific association with vascular risk factors between several age groups and subtypes of migraine and also in their families. A dataset (the Turkish Headache Database) from four tertiary headache centres in Turkey was used. This database included headache-defining features according to ICHD criteria based on face-to-face interviews and examinations by a Neurologist. Vascular risk factors of migraine without aura (MwoA), migraine with aura (MwA) and chronic migraine (CM) were compared between three age groups (under 30 years, 30-50 years and over 50 years) and in first-degree relatives of the patients. Our study included 2712 patients comprising 1868 (68.9 %), 246 (9.1 %) and 598 (22.1 %) subjects with MwoA, MwA and CH, respectively. This study showed that both the patients and the first-degree relatives were more frequently associated with vascular risk factors in CM than episodic MwA and MwoA. MwoA showed a weaker association with vascular risk factors than MwA and CM. Chronic migraine was associated with vascular risk factors at all ages and first-degree relatives as well. Vascular risk factors should be investigated with greater focus on chronic migraine. Chronic migraine was associated with vascular risk factors at all ages and first-degree relatives as well. Vascular risk factors should be investigated with greater focus on chronic migraine. To modify the conventional methods of grooving and direction during the single-door cervical laminoplasty (SDCL) in the subaxial cervical spine. The distance between the left and the right lamina-lateral mass junction at the upper, middle, and lower levels of each segment (DLL-U, DLL-M, DLL-L), angle between the posterior edge of the vertebral body and the lamina (AVL) and thickness of lamina (TL) were measured in the transverse plane. The parameters of preoperative computed tomography scans of 200 patients who had undergone SDCL were measured. The patients were divided into male and female groups and developmental canal stenosis (DCS) and non-DCS (NDCS) groups. DLL-M gradually increased from the cranial to the caudal except for C7, and DLL-L > DLL-M > DLL-U in each vertebra. AVL increased from C3 to C7, TL decreased from C3 to C5 and increased from C5 to C7, with both parameters showing no significant differences between the left and right sides. AVL of the DCS group was less than that of the NDCS group (P < 0.01). In the SDCL, the ideal surgical trough should be several discontinuous lines sloping from top to bottom, rather than a straight line. The abduction angle during drilling should gradually increase from C3 to C7 in the SDCL averaging 40 degrees. This method mentioned above improves the e
