Adolescents and Parents Attitudes about Marriage in Korea : The Importance of the Frequency of Parent-Adolescent Communications

This paper examines the association of parental attitudes regarding marriage with the children's same attitudes in Korea using a national representative sample of 1,184 adolescents aged 10 to 18 and their mothers and fathers. This study also appraises the role of parent-adolescent communication as a transmitting mechanism. Results indicate strong generational associations between adolescents' and their parents' attitudes towards marriage in Korea. Adolescents whose mothers or fathers are liberal with respect to cohabitation, marriage, and divorce also tend to think of cohabitation and divorce as possible options and deny the absoluteness of marriage in life. This study also found that when parents and children communicate frequently, stronger generational associations occur, suggesting that parent-adolescent communications play a key role in generational transmission of attitudes towards marriage in Korea.This work is supported by a grant from the University of Seou

Gender and Measuring-position Differences in the Radial Pulse of Healthy Individuals

AbstractIn this research, radial pulse differences according to gender and measuring positions in healthy individuals were investigated in an objective manner. A total of 372 healthy volunteers (189 males and 183 females) participated in this study. The radial pulse was measured at six different measuring positions using a multistep tonometry system. The pulse data were compared between males and females and between different measuring positions. Compared to the pulses in females, those in males were deeper and slower, with a longer diastolic proportion and a shorter systolic proportion. Amplitude of the radial pulse increased as it went distal. The pulse was deepest at the Cheock position and shallowest at the Gwan position. Compared to the right pulse, the radial augmentation index was higher and the main peak angle was larger in case of the left pulse. The results of this research show that the radial pulses in healthy individuals differ significantly according to gender and measuring positions

Attitudes Toward Married Womens Employment in Korea and Japan : Implications from Latent Class Analyses

In this article, we compare attitudes towards married women's employment in Korea and Japan using 2002 ISSP and 2003 KGSS data. In particular, we use the method of latent class analysis to investigate the structure of the viewpoints about wives' economic activities. We find that Japanese women and men are more liberal in their attitudes toward married women's employment than their Korean counterparts. Then applying the method of latent class analysis, we find that Korean women and men can be classified as four and two groups respectively, in terms of their attitudes towards wives' economic activities, and that both Japanese women and men can be divided into three groups. These differences in the structure of attitudes towards wives' labor force participation may be due to a number of institutional differences in the labor force experiences of women, especially, the childcare system and gender discrimination.This work is supported by a Korean Research Foundation Grant (KRF-2003-074-BM0007

Identification of Gene Expression Signature Modulated by Nicotinamide in a Mouse Bladder Cancer Model

BACKGROUND: Urinary bladder cancer is often a result of exposure to chemical carcinogens such as cigarette smoking. Because of histological similarity, chemically-induced rodent cancer model was largely used for human bladder cancer studies. Previous investigations have suggested that nicotinamide, water-soluble vitamin B3, may play a key role in cancer prevention through its activities in cellular repair. However, to date, evidence towards identifying the genetic alterations of nicotinamide in cancer prevention has not been provided. Here, we search for the molecular signatures of cancer prevention by nicotinamide using a N-butyl-N-(4-hydroxybutyl)-nitrosamine (BBN)-induced urinary bladder cancer model in mice. METHODOLOGY/PRINCIPAL FINDINGS: Via microarray gene expression profiling of 20 mice and 233 human bladder samples, we performed various statistical analyses and immunohistochemical staining for validation. The expression patterns of 893 genes associated with nicotinamide activity in cancer prevention were identified by microarray data analysis. Gene network analyses of these 893 genes revealed that the Myc and its associated genes may be the most important regulator of bladder cancer prevention, and the gene expression signature correlated well with protein expression data. Comparison of gene expression between human and mouse revealed that BBN-induced mouse bladder cancers exhibited gene expression profiles that were more similar to those of invasive human bladder cancers than to those of non-invasive human bladder cancers. CONCLUSIONS/SIGNIFICANCE: This study demonstrates that nicotinamide plays an important role as a chemo-preventive and therapeutic agent in bladder cancer through the regulation of the Myc oncogenic signature. Nicotinamide may represent a promising therapeutic modality in patients with muscle-invasive bladder cancer

Molecular cloning and expression of a novel human cDNA related to the diazepam binding inhibitor

AbstractIn order to isolate the unidentified autoantigens in autoimmune diabetes, a human pancreatic islet cDNA library was constructed and screened with the sera from the diabetic patients. From the library screening, one clone (DRS-1) that strongly reacted with the sera was isolated. Subsequent sequence analysis revealed that the clone was a novel cDNA related to the diazepam binding inhibitor. DRS-1 was expressed in most tissues including liver, lung, tonsil, and thymus, in addition to pancreatic islets. DRS-1 was in vitro translated and the recombinant DRS-1 protein was expressed in Escherichia coli and purified. The size of the in vitro translated or bacterially expressed DRS-1 protein was in agreement with the conceptually translated polypeptide of DRS-1 cDNA. Further studies are required to test whether or not DRS-1 is a new autoantigen in autoimmune diabetes

Genetic Analyses of the Chimeric CYP11B1/CYP11B2 Gene in a Korean Family with Glucocorticoid-Remediable Aldosteronism

Glucocorticoid-remediable aldosteronism (GRA) is an autosomal-dominant inheritable form of hyperaldosteronism with early onset hypertension. GRA is caused by unequal crossing-over of the steroid 11β-hydroxylase (CYP11B1) and aldosterone synthase (CYP11B2) genes. As a result of chimeric gene duplication, aldosterone is ectopically synthesized in the adrenal zona fasciculata under the control of adrenocorticotropin. Here, we describe three cases of GRA in a Korean family. The proband-a 21-yr-old female-was incidentally found to have high blood pressure (170/108 mmHg). Her 46-yr-old father had been treated twice for cerebral hemorrhage at the ages of 29 and 39 yr. Her 15-yr-old brother had a 2-yr history of hypertension; however, he was never treated. Their laboratory test results showed normokalemia, hyporeninemia, hyperaldosteronism, and a high plasma aldosterone concentration-to-plasma renin activity ratio. Normal saline loading failed to suppress aldosterone secretion. However, dexamethasone administration effectively suppressed their plasma aldosterone concentrations. Following genetic analyses with PCR and direct sequencing to document the chimeric gene and crossover site, respectively, we identified CYP11B1/CYP11B2 and determined the breakpoint of unequal crossover to be located between intron 2 of CYP11B1 and exon 3 of CYP11B2
