In Xenopus, the animal cap is very sensitive to BMP antagonists, which result in neuralization. In chick, however, only cells at the border of the neural plate can be neuralized by BMP inhibition. Here we compare the two systems. BMP antagonists can induce neural plate border markers in both ventral Xenopus epidermis and non-neural chick epiblast. However, BMP antagonism can only neuralize ecto...

The instrumentation of anterior vertebral body screws has become an important approach for the treatment of unstable fractures or curvature of the spine, but little attention has been paid to the starting point of placing the screws and the variability of the rib head position. We analysed the variability of rib head position in a Chinese population in terms of the spinal canal and vertebral bo...

Objective: The identification of landmarks in mandible is an important stage before dental procedures ın pediatric patients. purpose this study was to determine the location lingula mandible, mental foramen (MF) and lingual (LF) a paediatric population. 
 Methods: distance anterior, posterior, superior, inferior borders distal edge alveolar socket 1st molar tooth were measured. MF LF top c...

In this study, the influence of internal fixation systems on radiation therapy for spinal tumor was investigated in order to derive a theoretical basis for adjustment of radiation dose for patients with spinal tumor and internal fixation. Based on a common method of internal fixation after resection of spinal tumor, different models of spinal internal fixation were constructed using the lumbar ...

The decapentaplegic (dpp) gene encodes a long-range morphogen that plays a key role in the patterning of the wing imaginal disc of Drosophila (Nellen, D., Burke, R., Struhl, G. and Basler, K. 1996. Direct and long-range action of a DPP morphogen gradient. Cell 85, 357-368.). The current view is that dpp is transcriptionally active in a narrow band of anterior compartment cells close to the ante...

BACKGROUND This study correlates anatomic landmarks with radiographic densities and radiolucencies of the posterior pelvis, which assists in percutaneous iliosacral screw placement. METHODS Radio-opaque markers were placed on selected surfaces of cadaveric specimens and rotated under a fluoroscopic beam. Identified surfaces were described with angular measurements and anatomic characteristics...

Effects of Doxycycline on Cx43 Distribution and Cardiac Arrhythmia Susceptibility of Rats after Myocardial Infarction Abstract: This study aimed to observe the effects of doxycycline (DOX) on gap junction remodeling after MI and the susceptibility of rats to cardiac arrhythmia. The proximal left anterior descending coronary artery of rats was ligated to establish a myocardial infarction animal...
