본 논문에서는 대부분의 선형 집적회로와 집적 주입 논리 회로에 넓게 사용되고 있는 NPN 트랜지스터의 에미터 면적의 크기에 대한 순방향 전류 이득의 영향에 대해 연구하였다. 순방향 전류이득과 에미터 면적 사이의 관계를 실험과 시뮬레이션을 통해 확인하였다. 같은 에미터 길이에서 에미터 접합 깊이가 증가 할수록 에미터 전류 이득은 감소하였다. 측면 면적에 비해 에미터 바닥 면적 비율이 증가할수록 에미터 전류이득은 증가하였다. 이론과 시뮬레이션의 결과는 실험결과와 함께 아주 잘 일치하였다.

The present study was performed to determine the accuracy and reproducibility of calculating the mitral regurgitant orifice area with the proximal isovelocity surface area (PISA) method in dogs with experimental mitral regurgitation and in canine patients with chronic mitral insufficiency and to evaluate the effect of general anesthesia on mitral regurgitation. Eight adult, Beagle dogs for experimental mitral regurgitation and 11 small breed dogs with spontaneous mitral regurgitation were used....

a major social problem of the modern world and majority of these abusive drugs or their metabolites are excreted through the kidneys and, thus, the renal complications of these drugs are very common. Morphine, heroin, cocaine, nicotine and alcohol are the most commonly abused drugs, and their use is associated with various types of renal toxicity. The renal complications include a wide range of glomerular, interstitial and vascular diseases leading to acute or chronic renal failure. The present...

cells in the ventral lateral septum and ventrolateral periaqueductal gray before the test swim. These results suggest that citalopram may affect c-Fos expression in the central nucleus of the amygdala and bed nucleus of the stria terminalis distinctively and raise the possibility that upregulation of c-Fos in the ventral lateral septum and ventrolateral periaqueductal gray before the test swim may be one of the probable common mechanisms underlying antidepressant effect in the FST.

the CA3 area in organotypic hippocampal slice cultures. After OGD/reperfusion, neurons were found to be damaged; the organelles such as mitochondria, endoplasmic reticulum, dendrites, and synaptic terminals were swollen; and the PSD became thicker and irregular. Ethanolic phosphotungstic acid staining showed that the density of PSD was significantly decreased, and the thickness and length of the PSD were significantly increased in the OGD/reperfusion group compared to the control. The levels of...

In order to reproduce chronic cerebral hypoperfusion as it occurs in human aging and Alzheimer's disease, we introduced permanent, bilateral occlusion of the common carotid arteries (BCCAO) in rats (Farkas et al, 2007). Here, we induced BCCAO in two different rat strains in order to determine whether there was a strain difference in the pathogenic response to BCCAO. Male Wistar and Sprague-Dawley (SD) rats (250-270 g) were subjected to BCCAO for three weeks. Klüver-Barrera and cresyl violet...

Poor residual bone height in the posterior maxilla beneath the sinus is still a problem during dental implantation. Because the alveolar process tends to resorb with age and the maxillary sinus becomes larger. That is seems to be caused by the further bone resorption and edentulous-related maxillary sinus pneumatization due to osteoclastic erosion of the periosteal sinus floor leads to progressive hollowing out of the alveolar process from the apical aspect1-3). Therefore, available bone volume...

Every year, an estimated 30 million bisphosphonate prescriptions are written in the U.S. alone. It is estimated that pamidronate and zoledronate have been used in over 2.5million patients worldwide1). Some patients who have Paget's disease and osteolysis with metastatic bone disease may not be able to survive without bisphosphonate therapy. Others suffered from a osteoporosis may develop further spontaneous fractures if bisphosphonates are discontinuated.

a new VIGS system derived from the Soybean yellow common mosaic virus (SYCMV). Here, we investigated several environmental and developmental factors to improve the efficiency of a SYCMV-based VIGS system to optimize the functional analysis of the soybean. Following SYCMV: Glycine max-phytoene desaturase (GmPDS) infiltration, we investigated the effect of photoperiod, inoculation time, concentration of Agrobacterium inoculm, and growth temperature on VIGS efficiency. In addition, the relative...
