Protective and therapeutic effects of an extract mixture of alder tree, labiate herb, milk thistle green bean-rice bran fermentation, and turnip against ethanol-induced toxicity in the rat

An herbal extract mixture and yogurt added to the herbal extract mixture were tested for their protective and therapeutic effects on ethanol-induced liver injury. The herbal extract mixture, yogurt and commercial drugs were used for treatment for two weeks prior to administering a single oral dose of ethanol (3 g/kg body weight). The herbal extract mixture and yogurt added to the herbal extract mixture were found to provide protection against ethanol-induced toxicity comparable to the commercial drug treatment, according to the serum and histopathological analysis. It was also shown that co-treatment with herbal extract mixture and yogurt against a triple oral dose of ethanol (2 g/kg body weight, over one week) provided protection against ethanol toxicity. After the initial set of experiments, the herbal extract mixture and yogurt treatments were extended for three more weeks. When compared to the positive control, further treatment with both the herbal extract and yogurt significantly reduced liver injury and resulted in a lower grade of lipid deposition

Twenty-Year Experience of Heart Transplantation: Early and Long-Term Results

Background: We evaluated early and long-term results after heart transplantation (HTPL). Methods: One hundred five consecutive patients (male:female=80:25) who underwent HTPL between 1994 and 2013 were enrolled. Based on the changes in immunosuppressive regimen, the study patients were divided into two groups. Early and long-term clinical outcomes were evaluated and compared between the patients who underwent HTPL before (group E, n=41) and after July 2009 (group L, n=64). The group L patients were older (p＜0.001), had higher incidence of hypertension (p=0.001) and chronic kidney disease (p＜0.001), and more frequently needed preoperative mechanical ventilation (p=0.027) and mechanical circulatory support (p=0.014) than the group E patients. Results: Overall operative mortality was 3.8%, and postoperative morbidities included acute kidney injury (n=31), respiratory complications (n=16), reoperation for bleeding (n=15) and wound complications (n=10). There were no significant differences in early results except acute kidney injury between group E and group L patients. Overall survival rates at 1, 5, and 10 years were 83.8%, 67.7%, and 54.9%, respectively, with no significant difference between the two patient groups. Rejection-free rates at 1 and 5 years were 63.0% and 59.7%, respectively; rates were significantly higher in group L than in group E (p＜0.001). Conclusion: Despite increased preoperative comorbidities, group L patients showed similar early and long-term outcomes and significantly higher rejection-free rates when compared with group E patients

Yield property characterization for Au and TiN thin films by applying nanoindentation technique

We tried to apply the nanoindentation technique to yield strength characterization by modifying a previous research. Although the yield strength determining technique developed by Kramer et al. has been successfully demonstrated for large scale indentations on bulky metals, its applicability is still doubtful to nanoscale indentations on thin films with severe roughness, anisotropy, and interfacial constraint. In order to overcome these problems, we combined the nanoindentation technique with a three-dimensional indent visualization technique in this study. Nanoindentation tests were performed for Au and TiN thin films and their corresponding indents were scanned by using an atomic force microscope. From the three-dimensional pile-up morphology, a circular pile-up boundary was measured and input into the yield strength formulation as an effective yielded zone radius. The yield strengths calculated were directly compared with those from the microtensile test.open3

Cardiopulmonary function and scoliosis severity in idiopathic scoliosis children

PurposeIdiopathic scoliosis is a structural lateral curvature of the spine of unknown etiology. The relationship between degree of spine curvature and cardiopulmonary function has not yet been investigated. The purpose of this study was to determine the association between scoliosis and cardiopulmonary characteristics.MethodsNinety children who underwent preoperative pulmonary or cardiac evaluation at a single spine institution over 41 months were included. They were divided into the thoracic-dominant scoliosis (group A, n=78) and lumbar-dominant scoliosis (group B, n=12) groups. Scoliosis severity was evaluated using the Cobb method. In each group, relationships between Cobb angles and cardiopulmonary markers such as forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC, left ventricular ejection fraction, pulmonary artery flow velocity, and tissue Doppler velocities (E/E', E'/A') were analyzed by correlation analysis linear regression.ResultsIn group A, 72 patients (92.3%) underwent pulmonary function tests (PFTs), and 41 (52.6%) underwent echocardiography. In group B, 9 patients (75.0%) underwent PFT and 8 (66.7%) underwent echocardiography. Cobb angles showed a significant negative correlation with FVC and FEV1 in group A (both P<0.05), but no such correlation in group B, and a significant negative correlation with mitral E/A ratio (P<0.05) and tissue Doppler E'/A' (P<0.05) in group A, with a positive correlation with mitral E/A ratio (P<0.05) in group B.ConclusionPulmonary and cardiac function was significantly correlated with the degree of scoliosis in patients with thoracic-dominant scoliosis. Myocardial diastolic function might be impaired in patients with the most severe scoliosis

Effects of Immobilizations of rhBMP-2 and/or rhPDGF-BB on Titanium Implant Surfaces on Osseointegration and Bone Regeneration

The aim of this study was to examine the effects of immobilizing rhPDGF-BB plus rhBMP-2 on heparinized-Ti implants on in vivo osseointegration and vertical bone regeneration at alveolar ridges. Successful immobilizations of rhPDGF-BB and/or rhBMP-2 onto heparinized-Ti (Hepa/Ti) were confirmed by in vitro analysis, and both growth factors were found to be sustained release. To evaluate bone regeneration, rhPDGF-BB, and/or rhBMP-2-immobilized Hepa/Ti implants were inserted into beagle dogs; implant stability quotients (ISQ), bone mineral densities, bone volumes, osseointegration, and bone formation were assessed by micro CT and histometrically. In vivo study showed that the osseointegration and bone formation were greater in the rhPDGF-BB/rhBMP-2-immobilized Hepa/Ti group than in the rhPDGF-BB-immobilized Hepa/Ti group. The rhPDGF-BB/rhBMP-2 immobilized Hepa/Ti group also showed better implant stability and greater bone volume around defect areas and intra-thread bone density (ITBD) than the rhBMP-2-immobilized Hepa/Ti group. However, no significant differences were observed between these two groups. Through these results, we conclude rhBMP-2 immobilized, heparin-grafted implants appear to offer a suitable delivery system that enhances new bone formation in defect areas around implants. However, we failed to observe the synergetic effects for the rhBMP-2 and rhPDGF-BB combination

Prevalence of Stroke and Transient Ischemic Attack in Korean Elders - Findings From the Korean Longitudinal Study on Health and Aging (KLoSHA)

Background and Purpose-Studies on the epidemiology of stroke and transient ischemic attack (TIA) are very limited in Asian elderly populations. We investigate the prevalence, risk factors, and neuropsychiatric comorbidities of stroke and TIA in community-dwelling Korean elders. Methods-Standardized face-to-face interviews, neurological examinations, and physical examinations were conducted in 714 randomly sampled community-dwelling Korean elders aged >= 65 years. Diagnoses of stroke and TIA were made according to the World Health Organization criteria. Results-Age- and education-standardized prevalences of stroke, TIA, and cerebrovascular disorder ( implying stroke or TIA) were estimated to be 10.1%, 8.9%, and 15.4%, respectively, in Korean elders. Hypertension and current smoking were associated with the risk of stroke, whereas atrial fibrillation, high diastolic blood pressure, high serum low-density lipoprotein cholesterol, and hypertension were associated with the risk of TIA. Cerebrovascular disorder was associated with the risk of major depressive disorder, vascular dementia, and nonamnestic mild cognitive impairment (P<0.05). Conclusion-Prevalences of stroke and TIA in Korean elders were higher than in white elders. Stroke and TIA were associated with increased risk of depression and cognitive disorders.PARK J, 2007, PSYCHIAT INVEST, V4, P80YU KH, 2006, J KOREAN NEUROL ASS, V24, P535Jellinger KA, 2005, J NEUROL SCI, V229, P37, DOI 10.1016/j.jns.2004.11.018Petersen RC, 2004, J INTERN MED, V256, P183INOUE T, 2004, J STROKE CEREBROVASC, V13, P155Orlandi G, 2003, EUR J EPIDEMIOL, V18, P879Feigin VL, 2003, LANCET NEUROL, V2, P43Lee JH, 2002, J GERONTOL B-PSYCHOL, V57, pP47Sheehan DV, 1998, J CLIN PSYCHIAT, V59, P22Sheehan DV, 1998, J CLIN PSYCHIAT, V59, P34*AM PSYCH ASS TASK, 1994, DIAGN STAT MAN MENTWILLIAMS OD, 1989, AM J EPIDEMIOL, V129, P687HATANO S, 1976, B WORLD HEALTH ORGAN, V54, P541
