Today, congenital heart diseases may be treated without surgery through advances in interventional cardiology. However, complications such as infection and thrombus formation may develop due to foreign materials used during these procedures. Surgical intervention may be required for the removal of the device utilized for the procedure. In this case report, we present the surgical treatment of a...

BACKGROUND Some patients with a morphological right ventricle (mRV) in the systemic circulation require early intervention because of progressive systemic ventricular dysfunction or atrioventricular valve regurgitation. They may be eligible for anatomic repair (correction of atrioventricular and ventriculoarterial discordance) but require prior training of the morphological left ventricle (mLV)...

The aim of the present study is to explore the role of capillary disorder in coronary ischemic congestive heart failure (CHF). CHF was induced in rats by aortic banding plus ischemia-reperfusion followed by aortic debanding. Coronary arteries were perfused with plastic polymer containing fluorescent dye. Multiple fluorescent images of casted heart sections and scanning electric microscope of co...

The purpose of this study was to examine the effectiveness of a new glass polyphosphonate cement (Diamond) for orthodontic banding. Thirty-one subjects underwent in vivo testing to compare the failure rate of bands cemented using the test cement and bands cemented using a conventional glass polyalkenoate cement (Ketac-Cem) over a 6-month period at the beginning of active appliance therapy. In a...

As a prelude to investigating the mechanism of regression of pressure overload-induced left ventricular (LV) hypertrophy (LVH), we studied the time course for the development and subsequent regression of LVH as well as accompanying alterations in cardiac function, histology, and gene expression. Mice were subjected to aortic banding for 4 or 8 wk to establish LVH, and regression was initiated b...

P osttreatment tooth movement is inevitable, but its degree depends on a variety of factors that are both iatrogenic and innate to each patient. Although various retention techniques have been developed to minimize posttreatment movement, it is unrealistic to believe that the entire dentition can be retained in all dimensions. Relapse is usually considered an adverse phenomenon, but some dimens...

INTRODUCTION Long-term changes in the dentitions of orthodontic patients have been studied. However, most studies in the literature report findings after only a few years posttreatment. In this study, we examined records an average of 24 years after active treatment. The purpose was to answer 2 questions: (1) does irregularity increase with time after treatment, and (2) how much relapse can be ...
