Anomalies in amelogenesis may be due to developmental defects or abnormalities in different components of developing teeth and can affect dental development. We compared dental development in a group of children with molar-incisor hypomineralization (MIH) with that in age- and sex-matched controls. Dental age was determined using panoramic radiographs of 105 children (59 girls, 46 boys) aged 7-...

BACKGROUND Ultrasonography is often used in the evaluation of patients with ocular concerns; however, several pathologic conditions and even some age-related changes can have similar sonographic appearances. One approach that clinicians use is to assume that unilateral findings visible at normal gain are acute, whereas bilateral findings requiring high gain are chronic, especially in the elderl...

background and aims: in diagnosing inflammatory bowel disease, one of diagnostic way is upper gastrointestinal endoscopy, which helps in differential diagnosis of unspecified colitis as well. the aim of this study was to investigate the necessity of upper gastrointestinal endoscopy in patients with inflammatory bowel disease.   materials and methods: in this descriptive cross-sectional study, 3...

Despite the importance of extra-time in determining progression in specific soccer tournament matches, few studies have profiled the demands of 120-minutes of soccer match-play. With a specific focus on the extra-time period, and using a within-match approach, we examined the influence of prolonged durations of professional soccer match-play on markers of technical (i.e., skilled) performance. ...

Abstract The kinematics of the Milky Way (MW) and M31, dominant galaxies in Local Group (LG), can be used to estimate LG total mass. New results on M31 proper motion have recently been improve that estimate. Those are based kinematic priors sometimes guided evaluated using cosmological N -body simulations. However, properties simulated analogs could biased due effective power spectrum truncatio...
