Objectives: Jitter analysis with concentric needle electrode of the thoracic 9 (T9) paraspinal muscle (PM), where the needle EMG examination at rest is difficult, was performed in both amyotrophic lateral sclerosis (ALS) patients and the controls.

Methods: For the T9 PM, both upper limit for mean and individual mean consecutive difference (MCD) values and spike numbers were calculated according to jitter values of pairs from controls. In addition to the descriptive statistics, differences between two groups and T9 PM needle EMG and jitter analysis findings of patients were compared (p = 0.

Department of Orthodontics, Faculty of Dentistry, Hacettepe University, Ankara, Turkey. Electronic address:

Introduction: The objective of this study was to evaluate the effects of the miniplate application sites in the maxilla and the applied force vector changes during skeletally supported facemask application in adolescent patients with unilateral cleft lip and palate (UCLP) using finite element model (FEM) analysis.

Methods: A FEM was obtained from a cone-beam computed tomography image of a 12-year-old female patient with UCLP. Miniplates were placed on 3 different sites of the maxilla; 500 g of advancement force was applied bilaterally, parallel (0°), and downward (-30°) to the occlusal plane.

We investigate alternative strategies against reference bias and postmortem damage in low coverage paleogenomes. Compared to alignment to the linear reference genome, we show that masking known polymorphic sites and graph alignment effectively remove reference bias, but only starting from raw read files. We next study approaches to overcome postmortem damage: trimming, rescaling, and our newly developed algorithm, bamRefine (github.
