  • This study aimed to recover the ovarian function through in vitro culture of preantral follicles from aged mice. First, we isolated the preantral follicles from ovaries of sixty-seven-week old B6D2F1 mice with decreased fecundity to know how many follicles were present in them, which was 6 preantral follicles including 2 primary, 2 early secondary and late secondary follicles from 8 aged mice. It was confirmed that a few follicles (~2) were present in aged mice through histological analysis compared to adult mice as control. The 9 days of in vitro culture of preantal follicles showed in vitro growth and induced maturation after treatment with hCG (2.5 IU/mL) and EGF (5 ng/mL). Cumulus cells in the cumulus-oocyte complexes (COCs) were removed using hyaluronidase and oocytes at the germinal vesicle (GV) and GV breakdown (GVBD) were obtained from preantral follicle culture of aged mice in vitro. In conclusion, these observations demonstrated that there still were a few preantral follicles in the ovaries of 67 week-old mice, which we were able to culture in vitro and oocytes were obtained from them. This study proposed an in vitro culture system using preantral follicle as a therapeutic strategy for fertility preservation in humans for assisted reproductive medicine.

  • This study showed that the association between solidarity and conflict is mediated by the communication of grandmothers and an adult child at the dyadic level. The common fate model (CFM) was designed to model mediation effects at the level of dyads. Participants consisted of 297 grandmother dyads and their adult child who were rearing preschool-aged grandchildren in Seoul and Gyeonggi-do. For analysis at the dyadic level, grandmothers and adults responded to the same questionnaire on the same variables. SPSS 23.0 performed descriptive statistical analysis and correlation analysis. The structural equation model (SEM) was estimated with AMOS 23.0. We tested the mediation model using the maximum likelihood method. Model fit index used the chi-square statistic, the incremental fit index (IFI), the comparative fit index (CFI), the root mean square error of approximation (RMSEA). The statistical significance of the indirect effect was examined using a bootstrapping procedure. The results are as follows. First, in the CFM, the direct effect between solidarity and conflict was significant. Therefore, the higher the solidarity, the lower conflict of grandmothers and an adult child. Second, the association between solidarity and conflict is mediated by communication at the dyadic level. Based on the results of this study, we discussed ways to strengthen the capacity of co-parenting between grandmothers and an adult child.

  • The purpose of the study was to provide good fitting of ready-to-wear pants for adult women. To pursue this purpose, the anthropometric data of Korean in 1992 (ADaM(R) 1.0) were analyze. The subjects were 1,580 women aged from 18 to 50 years. The body measurements of six age groups were compared. The results of data analysis showed that the height measurements( waist height, trochanter height, glutial height, perinneum height) of the late 40's were about 3cm shorter than those of the early 20's. The waist circumference of old subject group was 14.1cm larger than those of the young subject group. With rapid growing of waist circumference, the difference of hip and waist circumference was getting smaller with aging. The average difference between hip and waist circumferences of young adult group (18 to 24 yrs) was 24.3cm (SD 3.6cm) and the meaurement of old adult group (45 to 50 yrs) was 15.0cm (SD 5.6cm). The size of the women's pants which were manufactured by the top 50 manufacturers in Korea were compared. The difference between hip circumference and waist circumference listed on the size tag ranged from 12cm to 32cm. The body measurements of subjects and the standard size categories for pants were compared. The results showed that larger size categorise needed to be added to give better fits for older adult group.

  • BACKGROUND/OBJECTIVES: This study examined the relationship between famine exposure in early life and the risk of type 2 diabetes in adulthood during the 1959-1961 Chinese Famine. SUBJECTS/METHODS: A total of 3,418 individuals aged 35-74 years free of diabetes from two studies in 2006 and 2009 were followed up prospectively in 2009 and 2012, respectively. Famine exposure was classified as unexposed (individuals born in 1962-1978), fetal exposed (individuals born in 1959-1961), child exposed (individuals born in 1949-1958), and adolescent/adult exposed (born in 1931-1948). A logistic regression model was used to assess the relationship between famine exposure and diabetes after adjustment for potential covariates. RESULTS: During a three-year follow-up, the age-adjusted incidence rates of type 2 diabetes were 5.7%, 14.5%, 12.7%, and 17.8% in unexposed, fetal-exposed, child-exposed, and adolescent/adult-exposed groups, respectively (P < 0.01). Relative to the unexposed group, the relative risks (95% confidence interval) for diabetes were 2.15 (1.29-3.60), 1.53 (0.93-2.51), and 1.65 (0.75-3.63) in the fetal-exposed, child-exposed, and adolescent/adult-exposed groups, after controlling for potential covariates. The interactions between famine exposure and obesity, education level, and family history of diabetes were not observed, except for the urbanization type. Individuals living in rural areas with fetal and childhood famine exposure were at a higher risk of type 2 diabetes, with relative risks of 8.79 (1.82-42.54) and 2.33 (1.17-4.65), respectively. CONCLUSIONS: These findings indicate that famine exposure in early life is an independent predictor of type 2 diabetes, particularly in women. Early identification and intervention may help prevent diabetes in later life.

  • The purpose of this study were to explain the difference in body dimensions and body shape between the early in the twenties and the late in the twenties and to get information clothing construction. Subject were 483 Korean males, which were extracted from men's physique investigation on June to August in 1989, consisted of 149 aged $19\~24$ and $25\~29$. T-test and factor analysis were applied to 52 measurement items and 58 indices. The Result of the study were as follow; 1. As regards $19\~24$ aged group, they were taller their waistband level was higher than the late in the twenties. Upper arm and thigh were thick in comparison with trunk. As the difference between shoulder and waist in dimension was great, they showed reverse triangular silhouette. As regard $25\~29$ aged group, their body from variation between individual was greater than that of 19~24 aged group and they were obese on mainly waist and abdominal parts. For that reason, waist band level became low and their shoulder and hip looked slim relatively that reason, waist band level became low and their shoulder and hip look slim relatively to bust and waist parts. 2. Between $19\~24$ aged and $25\~29$ aged groups, as each had charicteristic body from, there was the difference in factor structure. 3. The change of men's body from with age in their twenties was obeseness on the whole body but the increasing rate of upper arm and thigh girth was less than that of trunk girth.

  • Epstein-Barr virus (EBV) is an extremely common herpesvirus that may cause asymptomatic infection or various diseases, including infectious mononucleosis, certain lymphoproliferative diseases and several types of neoplasms. Vaccine development is an important strategy to reduce the burden of EBV-associated diseases and the timing of vaccinations should be before primary infection occurs. In the past, more than 90% of Thai children were infected with EBV in early childhood. Now, due to the improved healthcare system in Thailand, we aim to determine current prevalence of EBV infection among people in different age groups. A total of 538 sera were collected from residents of Khon Kaen province in northeastern Thailand for detecting anti-EBV IgG. Sera of infants under 2-years-old were also tested for anti-EBV IgM and EBV-DNA. The prevalence of anti-EBV IgG was 47.1% (95% CI: 23.3-70.8) in infants aged 0-6 months, 34.9% (95% CI: 23.1-46.7) in those aged 6-24 months, 87.9% (95% CI: 79.5-96.3) in children aged 3-5 years and then maintained at above 95% through adulthood. These seropositivity rates among Thai children remain similar to those found in a previous study conducted 20 years ago. Thai children are still exposed to EBV from an early age. Therefore, a prophylactic vaccine should be given within the first two years of life.

  • Background: Little is known about the cancer screening prevalence and correlates in older adults from different racial backgrounds. In the context of heightened efforts for prevention and early diagnosis, we collected information on screening for two major types of cancers: cervical and breast cancer in order to establish their prevalence estimates and correlates among older South African women who participated in the Study of Global Ageing and Adults Health (SAGE) in 2008. Materials and Methods: We conducted a national population-based cross-sectional study with a multi-stage stratified cluster sample of 3,840 individuals aged 50 years or older in South Africa in 2008. In this analysis, we only considered the female subsample of (n=2202). The measures used included socio-demographic characteristics, health variables, anthropometric and blood pressure measurements. Multivariable regression analysis was performed to assess the association of socio-demographic factors, health variables and cancer screening. Results: Overall, regarding cervical cancer screening, 24.3% ever had a Papanicolaou (PAP) smear test, and regarding breast cancer screening, 15.5% ever had a mammography. In multivariate logistic regression analysis, younger age, higher education, being from the White or Coloured population group, urban residence, greater wealth, and suffering from two or more chronic conditions were associated with cervical cancer screening, and higher education, being from the White or Indian/Asian population group, greater wealth, having a health insurance, and suffering from two or more chronic condtions were associated with breast cancer screening. Conclusions: Cancer screening coverage remains low among elderly women in South Africa in spite of the national guideline recommendations for regular screening in order to reduce the risk of dying from these cancers if not detected early. There is a need to improve accessibility and affordability of early cervical and breast cancer screening for all women to ensure effective prevention and management of cervical and breast cancer.

  • Purpose: The aim of this study was to identify the age-related differences in risk perception of breast cancer and the age-related differences in predictors of risk perception. Method: The subjects were 553 women aged from 15 to 64 who lived in Seoul, Kwang-Ju, Jeon-nam province. Data was collected by self-reported questionnaire surveys using convenience sampling. The collected data was analyzed using descriptive statistics, F-test with Scheffe test, and stepwise multiple regression with SPSS-Win 10.0 version. Result: Risk perception of breast cancer was different by age group. Especially, risk perception in teenagers and the 50~64 years group was lower than the other groups. Additionally, general fear of breast cancer, information seeking style, experience, and knowledge were different between the age groups. The results of multiple regression analyses predicting risk perception indicated the following significant predictors: general fear and knowledge in all the subjects, general fear and experience in the 20~29 years group, and general fear in the other age groups. Conclusion: These results suggested that the construction of educational messages for breast cancer prevention and early detection should be designed differently for each age group.
