This paper presents a robust method for the automated segmentation and quantitative measurement of reflections from single ommatidia in the butterfly compound eye. Digital pictures of the butterfly eye shine recorded with a digital camera are processed to yield binary images from which single facet centers can be extracted using a morphological image analysis procedure. The location of the face...

Extending previous research on the relation of Big-Five personality with right-wing authoritarianism and social dominance orientation, we examined the relationships of Big-Five facet scores rather than factor scores. The results (N = 332) of stepwise regression analyses showed that Openness to Experience was the only significant predictor of right-wing authoritarianism at the factor level, wher...

Retrospective case-control study.Unilateral expansive open-door cervical laminoplasty with miniplate fixation is an efficient and increasing popular surgery for multilevel cervical spondylotic myelopathy. Axial symptoms are the most frequent complaints after cervical laminoplasty. But the mechanisms have not been fully clarified yet.The objective of this study is to compare the clinical and rad...

The ∼37 million-year-old Birket Qarun Locality 2 (BQ-2), in the Birket Qarun Formation of Egypt's Fayum Depression, yields evidence for a diverse primate fauna, including the earliest known lorisiforms, parapithecoid anthropoids, and Afradapis longicristatus, a large folivorous adapiform. Phylogenetic analysis has placed Afradapis as a stem strepsirrhine within a clade of caenopithecine adapifo...

STUDY DESIGN A descriptive in vitro study on isolation and differentiation of human mesenchymal stem cells (MSCs) derived from the facet joints and interspinous ligaments. OBJECTIVE To isolate cells from the facet joints and interspinous ligaments and investigate their surface marker profile and differentiation potentials. SUMMARY OF BACKGROUND DATA Lumbar spinal canal stenosis and ossifica...

The precise cause of low back pain based on clinical history, physical examination, radiological imaging, and electrophysiological testing can be identified in only 15% of patients in the absence of disc herniation and neurological deficit. The prevalence of chronic lumbar zygapophysial (facet) joint pain ranges from 15% to 45% utilizing comparative local anesthetic blocks in controlled setting...

BACKGROUND The cause of the adjacent segment degeneration (ASD) after fusion remains unknown. It is reported that adjacent facet joint stresses increase after anterior cervical discectomy and fusion. This increase of stress rate may lead to tissue injury. Thus far, the load rate of the adjacent segment facet joint after fusion remains unclear. METHODS Six C2-C7 cadaveric spine specimens were ...

Objective Moderate sedation has limits in managing children’s behavior. Existing literature lacks insight into parental perceptions about the topic. This study aimed to understand mothers’ perceptions concerning sedation after their children undergone dental treatment under sedation. Methods Twelve mothers and one godmother of 1.3-8.4 year-old children with definitely negative behavior in the d...
