Floral development was investigated in Ruta graveolens and Psilopeganum sinense, representing two genera in the tribe Ruteae. Special attention was paid to the sequence of initiation of organ whorls in the androecium and gynoecium. The antepetalous stamens arise at the same level as the antesepalous stamens in both species. The carpels are antepetalous in both taxa, indicating the androecium in...

Radioactive xenon-133 was used to study the pattern of regional lung function in 35 scoliotic patients and 10 normal subjects in the sitting posture. The scoliotic curves were classified into three anatomical sites: high, if the apical vertebra was located between Thl and Th5; mid, between Th6 and ThlO; and low, between Thll and L4; only the primary curve was considered and in 70% of the patien...

introduction: the purpose of this clinical study was to compare the accuracy of working length (wl) determination using cone-beam computed tomography (cbct), conventional periapical radiographies and electronic apex locator. methods and materials: this study was conducted during root canal treatment of 19 patients with a total of 30 single-rooted teeth diagnosed with apical periodontitis. after...

The organ of Corti harbors highly specialized sensory hair cells and surrounding supporting cells that are essential for the sense of hearing. Here, we report a single cell gene expression data analysis and visualization strategy that allows for the construction of a quantitative spatial map of the neonatal organ of Corti along its major anatomical axes. The map displays gene expression levels ...

A 29-year old male was transferred to our hospital with an abnormal chest X-ray finding diagnosed as hypertrophic cardiomyopathy with apical necrosis and aneurysm formation. Four years after the initial hospitalization, we confirmed the aneurysm and necrosis using both integrated positron emission tomography (PET) and computed tomography (CT) scanning. The F-18 2-fluoro-2-deoxy-D-glucose (FDG) ...

introduction: the aim of this study was to evaluate the accuracy of two electronic apex locators (smarpex and novapex) in detecting apical perforation. materials and methods: after access cavity preparations, the working length was determined by the first examiner before and after perforation with a stereomicroscope by introducing a k-file size 10 into the canal and size 25 k-file up to the per...
