Background: The prevalence of TMD (temporomandibular disorder) in children and early adolescents varies widely. can cause permanent facial deformities affect occlusion speech, which will growth, development, quality life. For prevention, detection is needed. However, often not possible due to a lack understanding the normal shape condyle. Research on condyle symmetry has been much done. Purpose...

BACKGROUND The stapes, an ossicle found within the middle ear, is involved in transmitting sound waves to the inner ear by means of the oval window. There are several developmental problems associated with this ossicle and the oval window, which cause hearing loss. The developmental origin of these tissues has not been fully elucidated. RESULTS Using transgenic reporter mice, we have shown th...

BACKGROUND Silver nanoparticles (Ag NPs) displayed strong activities in anti-bacterial, anti-viral, and anti-fungal studies and were reportedly efficient in treating otitis media. Information on distribution of AgNPs in different compartments of the ear is lacking. OBJECTIVE To detect distribution of Ag NPs in the middle and inner ear and transportation pathways after transtympanic injection....

BACKGROUND The diagnosis of sinus venosus defects remains a matter of debate. It is crucial to provide solid anatomical criteria, by identifying the very nature of the atrial septum relative to sinus venosus defects, to diagnose and differentiate them from other interatrial communications. OBJECTIVE This study was designed to reestablish the anatomical criteria for the diagnosis of sinus veno...

Addition of nanoparticles into a fluid can improve the heat transfer performance base in exchangers. In this work, preparation method and process nanofluids are introduced, thermal properties nanofluids, such as conductivity viscosity, discussed deeply. This paper summarizes various theoretical models viscosity nanofluids. A comprehensive literature survey on applications limitations has been c...

CYTOLOGY Low-grade atypia Usual ductal hyperplasia Cell population Monomorphic Polymorphic Nuclear shape Round or oval Oval, elongated to tapered Nuclear contours Smooth Grooves and notches Chromatin Homogeneous, fine, hyperchromatic Granular, slightly open, euchromatic Nucleoli Often inconspicuous Small nucleoli present Nuclear pseudoinclusions Absent Often present Cytoplasm amount Increased M...

A new fully automatic method for detecting auroral ovals in images produced by the NASA IMAGE satellite’s Far Ultra Violet (FUV) sensor is introduced. The method exploits the shape characteristics of the auroral oval and utilizes domain knowledge. The shape exploitation involves an efficient Hough-based process. Experimental results show that the new method can accurately detect the auroral ova...

Two types of balloon are usually employed to perform balloon-assisted coil placement in cerebral aneurysms: oval, guide-dependent balloons for sidewall aneurysms and round balloons for bifurcation aneurysms. We report on the use of a new, more compliant, guide-dependent oval balloon microcatheter to seal wide-neck bifurcation aneurysms with coils during endovascular occlusion.

PURPOSE The aim of the present study was to evaluate the effects of posts with different morphologies on stress distribution in an endodontically treated mandibular premolar by using finite element models (FEMs). MATERIALS AND METHODS A mandibular premolar was modeled using the ANSYS software program. Two models were created to represent circular and oval fiber posts in this tooth model. An o...
