Abstract Case Description- A three-day-old male Kordi lamb had a soft painless fluctuating mass on the mid-parietal region, with no clinical signs except difficulty in standing; was referred to the clinic. Clinical Findings- Clinical examination revealed a normal body temperature, a heart rate, a respiratory rate, and inability to stand without any congenital defects Three-dimensional comp...
In this work, oscillator strength and quantum efficiency of new spherical GaN/AlGaN quantum dot was investigated. In order to obtain these parameters, at first, Schrödinger equation is solved in GaN/AlGaN spherical coordinate system in effective mass approximation, and energy level, wave function and transition matrix element of the parameter are obtained. The results show that oscillator stre...
Nowadays, different materials have been used for regeneration of interosseous defects and Neo-Os is one of them. The objective of this study was to evaluate histologically the influence of Neo-Os® particles on bone regeneration using rabbit caivarias defects with and without protection of Gore-Tex® barrier membrane. A cutaneous- periosteal incision and flap was made on the forehead of 32 rabbit...
Background and purpose: Adipose - drived stem cells are multipotent cells that capable to diffrentiate in to osteogenic cells. On the other hand, the scaffold of chitosan and gelatin are biodegradable and compatible used for tissue repair. This study evaluated the repair of femoral bone defect using adipose-derived stem cells on gelatin – chitosan membrane in adult Albino Wistar rats by radiog...
Background For each congenital heart defect (CHD) knowledge of morphological and functional variations is crucial in order to assess an individual case and initiate specific therapy, if necessary. Specific data are widely lacking. CMR-based values exist only for left ventricular (LV) and right ventricular (RV) volumes of children and adults with normal anatomy. Therefore, we sought to provide v...
OBJECTIVE Congenital heart diseases are among the most frequent major congenital anomalies. One of the suspected reasons for congenital heart defects is overweight and obesity of mother during prepregnancy and pregnancy. We studied the relationship between maternal overweight and obesity and the risk of congenital anomaly. METHODS All of children with congenital heart defect (164 infants with...
Recent experiments show the thermal growth of dislocation lines in unltapure bcc He. The activation energy for the growth of the dislocation lines is found to agree with the activation energy of mass diffusion. We propose that these dislocations are topological defects in the phase of the complex order-parameter which describes the dynamic zero-point atomic correlations, unique to the bcc phase...
A female neonate born at term with a mass at the umbilicus (Fig. 1). Prenatal ultrasound at 22 weeks gestation had noted polyhydramnios, macrosomia, a single umbilical artery and a small ventricular septum defect. Fluorescence in situ hybridization (FISH) analysis at 27 weeks gestation did not identify any chromosomal abnormalities. At birth, the umbilical ring seemed intact and there was no re...
The aim of the study was to evaluate the prevalence of restrictive ventilatory defect and to determine the risk factors in subjects with spirometrically-defined restrictive ventilatory defect. We used the population-based, fourth-2, 3 (2008, 2009) and fifth (2010-2012) Korea National Health and Nutrition Examination Survey (KNHANES) to analyze 15,073 subjects, aged ≥40 yr who underwent spiromet...
A calcified amorphous tumor (CAT) of the right atrium (RA) is an exceedingly rare non-neoplastic cardiac mass. It was initially described in 1997 and only a handful of cases has been published so far. We present a case of tumor in 77-year-old male, in the RA that attached to the rim of the fossa ovalis, with classic pathological and clinical findings. Under cardiopulmonary bypass (CPB) and bica...
