Three-Dimentional (3-D) printing is currently a popular technique that used in many sectors. Potentially, this technology expected to replace conventional manufacturing the coming years. It accelerating gaining attention due its design freedom where objects can be produced without imagination boundaries. The review presents perspective on application of 3-D based various fields. However, ordina...

Quadricuspid aortic valve is a rare congenital anomaly that may cause aortic regurgitation. A 77-year-old male patient was referred to our clinic with complaints of stable angina pectoris. We report a case of a quadricuspid aortic valve diagnosed by 3-dimentional transthoracic echocardiography.

We consider digits-deleted sets or Cantor-type sets with β-expansions. We calculate the Hausdorff dimension d of these sets and show that d is continuous with respect to β. The d-dimentional Hausdorff measure of these sets is finite and positive.

OBJECTIVE To evaluate the left venticular myocardial deformation parameters in normotensive obese children and adolescents by using 2-D speckle tracking echocardiography. METHODS This observational cross-sectional study included 69 children and adolescents (aged between 10-18), 38 were normotensive obese and 31 were normal weighted. All children underwent detailed two- dimentional, Doppler an...

A novel homocyclotirucallane, sinetirucallol (1), and two additional new dihydrophenanthrenes, sinensols G (2) and H (3), were isolated from the aerial parts of Spiranthes sinensis (Pers.) Ames. Their structures were determined by various spectral analyses, including MS and two-dimentional nuclear magnetic resonance techniques. The structure of compound 1 was further confirmed by single-crystal...

BACKGROUND Congenital radioulnar synostosis is a rare malformation of the upper limb, with functional limitations of the limb. CASE REPORT A 10-year-old child with pain and restricted mobility of the elbow joint was admitted to the hospital. Plain film radiography and CT examination was performed. Radiological examinations showed a congenital radioulnar synostosis. The child underwent surgica...

Structure-controlled Pt-based catalysts have been known to exhibit improved electrocatalytic activities due to particularly modulated surface structures favorable for alcohol electrooxidation. We report PtNi alloy dendrite structure for formic acid electrooxidation prepared by a thermal decomposition method. The Pt-Ni nanodendrites display 3-dimentional nanostructure and homogeneous alloy forma...
