4 ± 4.1 mm in Group 2, and 36.7 ± 3.3 mm in Group 3 (p < 0.05). There was no significant difference between Group 2 and Group 3 in respect of mean lamina angle (44º vs 45º) but it was lower in Group 1 (35º).

To assess the craniocervical junction (CCJ) by using radiological measurements in patients with adolescent idiopathic scoliosis (AIS) and Scheuermann?s kyphosis (SK), and to compare those reults with healthy adolescent population.
Patients were assigned to three groups. Group 1 consisted of AIS patients, Group 2 consisted of patients with SK, and Group 3 was the control group who did not have any spinal disorder. The groups were matched based on age and gender. Major Cobb angle and kyphosis angle were measured on X-Ray. asion-axial interval (BAI), basion-dens interval (BDI), posterior atlantodental interval (PADI), anterior atlantodental interval (ADI), atlanto-occipital interval (AOI), and Power?s ratio were measured by computerized tomography. The results were compared in each group statistically.
A total of 120 participants, comprised of 78 (65%) female and 42 (35%) male were included in the study. There was no statistically difference between 3 groups based on age and gender (p > 0.05). According to the measurements, Group 3 had significantly higher PADI measurements than Group 1 (p=0.01). The ADI measurements of Group 2 were significantly higher than those of Group 1 and Group 3 (p=0.01). Group 3 had significantly higher BDI measurements than Group 1 and Group 2. (p=0.01). The Power ratios of Group 1 and Group 3 were statistically higher than that of Group 2 (p=0.01). There were no statistically significant differences between the groups in terms of AOI and BAI measurements (p=0.84, p=0.18, respectively).
The presence of AIS and SK may affect the measurement of CCJ, and it may be considered to evaluate instability of the region.

In radiogenomics, certain MRI features have been recently associated to predict genetic alterations. We analyzed certain MRI features as well as six major genetic biomarkers, investigated their associations, and evaluated their prognostic roles in glioblastomas (GBMs).
Strict criteria included newly diagnosed GBM with optimal treatments. Simple manual imaging characteristics (tumor side, location, enhancement, diameter, depth, radiographic necrosis, and edema) were obtained from preoperative conventional MRI. Furthermore, all the status of the MGMT promoter, Chromosome 1p and 19q, IDH, TERT, and BRAF in tumor tissues were detected.
Among 126 inpatients, 60 cases were selected and enrolled in the study. The status of the MGMT promoter was significantly associated with the grade of radiographic necrosis (p = 0.033). The rate of 19q deletion was significantly higher in tumors with the ring-shaped peritumoral edema (PTE) (p = 0.035) and in tumors with the ring-enhanced trait (p = 0.023). Univariate analysis showed that a low PTE index and MGMT promoter methylation were both unfavorable prognostic factors. While the PTE index statistically dropped out, the status of the MGMT promoter and the depth of the tumor were observed to be independent prognostic factors in multivariate analysis.
Based on simple neuroimaging metrics, novel connections between features of preoperative conventional MRI and status of major genetic biomarkers were observed, especially for the MGMT promoter and 19q.

To investigate the effects of electromagnetic waves (EMWs) from mobile phones (MPs) on rat brains of rats by morphological and biochemical analysis.
EMW was applied for two hours/day until birth in stand-by fetal and EMW fetal groups and postnatal 60 < sup > th < /sup > day in stand-by and EMW groups. The control group was not exposed to MP. On postnatal 60 < sup > th < /sup > day, brain malondialdehyde (MDA) and glutathione (GSH) levels were measured, and western blot analysis was performed to determine glial fibrillary acidic protein (GFAP) content. Hematoxylin and eosin staining and GFAP immunohistochemistry were applied. CCT245737 Trigeminal nerves were examined using the transmission electron microscope.
In comparison to controls, rats exposed to MP in stand-by or talk modes had significantly increased neuronal damage in the cortex and hippocampus. Increased MDA levels in the EMW group and decreased GSH levels in the stand-by, EMW fetal and EMW groups were found compared with controls. Increased GFAP content in the EMW group and increased GFAP staining in the EMW fetal and EMW groups compared to controls were observed. EMW group had a significantly decreased number of myelinated axons than control animals.
The results of this study suggests that 1800 MHz EMWs (SAR=1.79 W/kg) exposure in the prenatal and early postnatal life may lead to trigeminal nerve damage in addition to oxidative stress-induced neuronal degeneration and astroglial activation in the rat brain. Effects seem to be mode related, being more detrimental in groups exposed to MP during talk mode.

This study aimed to evaluate the clinical results of patients who underwent unilateral dynamic rod stabilization after unilateral facet joint excision during spinal surgery.
Twenty patients who were diagnosed with degenerative spinal disease or spinal tumor, who were operated on using a unilateral approach, who underwent facet joint resection, and who were stabilized with a unilateral dynamic rod were examined. Visual analog scale (VAS) and Oswestry disability index (ODI) scores were used to clinically evaluate the cases during the preoperative and postoperative periods. Radiological examinations for sagittal alignment, segmental angle, and bone fusion were also conducted.
The mean preoperative VAS and ODI scores were 7.6 and 71.7, respectively, and the 12th postoperative month scores were 1.1 and 12.8, respectively. The mean segmental angle measurements were 22.1° in the preoperative period and 21.6° at the postoperative 12th month. No deterioration in sagittal alignment and no bone fusion were observed.
