The purpose of the study is to examine whether the model based on the Theory of Reasoned Action (TRA) succeeds in predicting mothers' intention to vaccinate their daughters against the human papilloma virus infection. Questionnaires were distributed among convenience sample of 103 mothers of daughters 18 years and younger. Approximately 65% of mothers intend to vaccinate their daughters. Behavioral beliefs, normative beliefs, and level of knowledge had a significant positive effect on mothers' intention to vaccinate their daughters. High levels of religiosity were found to negatively affect mothers' intention to vaccinate their daughters. The TRA combined with level of knowledge and level of religiosity succeeds in predicting mothers' behavioral intentions regarding vaccinating daughters. This indicates the significance of nurses' roles in imparting information and increasing awareness among mothers. Copyright © 2011. Published by Elsevier Inc.

Maternal depression is associated with increased risk of psychiatric illness in offspring. While risk may relate to depressed mothers' difficulties regulating emotions in the context of interacting with offspring, physiological indicators of emotion regulation have rarely been examined during mother-child interactions-and never among mother-adolescent dyads in which both mother and adolescent have histories of major depressive disorder (MDD). We examined changes in high-frequency heart rate variability (HF-HRV), an indicator of parasympathetic (vagal) function that has been related to depression, stress, social engagement, and emotion regulation, in 46 mother-daughter dyads (23 in which both mother and daughter had an MDD history and 23 never-depressed controls). Hierarchical linear models evaluated changes in HF-HRV while mother-daughter dyads engaged in discussions about shared pleasant events and relationship conflicts. While control dyads displayed positive slopes (increases) in HF-HRV during both discussions, MDD dyads displayed minimal change in HF-HRV across discussions. Among controls, HF-HRV slopes were positively correlated between mothers and daughters during the pleasant events' discussion. In contrast, HF-HRV slopes were negatively correlated between MDD mothers and daughters during both discussions. Vagal responses observed in control mother-daughter dyads suggest a pattern of physiological synchrony and reciprocal positive social engagement, which may play a role in adolescent development of secure social attachments and healthy emotion regulation. In contrast, MDD mothers and daughters displayed diminished and discordant patterns of vagal responsiveness. More research is needed to understand the development and consequences of these patterns of parasympathetic responses among depressed mother-daughter dyads. © 2016 Wiley Periodicals, Inc.

The purpose of this article is to describe, from the perspective of the adult daughter, the mother-daughter relationship in the context of chronic conflict. Grounded theory methodology was used. An online recruitment strategy was used to identify a sample of adult daughters (N = 13) who self-identified as having an abusive relationship with their aging mother. Data collection was completed through semi-structured telephone interviews. Daughters framed their relationship around their perceptions of past childhood injustices. These injustices invoked strong negative emotions. Daughters had equally strong motivations for sustaining the relationship, driven by desire to reconcile their negative experience through seeking validation and futile-hoping as well as a sense of obligation to do due diligence. Together these factors created an environment of inevitable confrontation and a relationship defined by chronic conflict. Findings from the study provide theoretical insights to the conceptualization of aggression, power relationships, and the development of elder abuse and neglect.

Preconception counseling (PC) significantly and inexpensively reduces risks of reproductive-health complications for women with diabetes. Our validated technology-based preconception counseling intervention, READY-Girls , is tailored for female teens with type 1 (T1D) and type 2 (T2D) diabetes and targets decision-making regarding effective family planning and seeking PC. Our teen-focused research was instrumental in changing the American Diabetes Association's Practice Recommendations to specify that preconception counseling should "Start at puberty…". This directive requires support from well-informed mothers of teens. Our goal is to provide both teen girls and their mothers with preconception counseling knowledge, and provide mothers with sex-communication training. Evaluation should focus on mother-daughter dyads. This feasibility study explored mother's and daughter's awareness and knowledge of diabetes and pregnancy, and preconception counseling; and compared mother-daughter responses using dyadic analyses. A mixed-method design was conducted with 10 mothers of daughters with T1D. Mothers were given READY-Girls intervention and completed knowledge and support questionnaires. Their responses were compared to those of their daughter's who were participating in a large randomized, control intervention trial with READY-Girls . The major theme from one-on-one interviews was, "I know nothing about diabetes/pregnancy risks and PC". Mother's and daughter's perceptions of having limited knowledge were confirmed by low knowledge scores. Mothers perceived giving higher levels of support compared to their daughter's perceptions of receiving support. Mothers can play a vital role in initiating discussions regarding reproductive-health with their daughters and reinforcing preconception counseling. Mother-daughter team approach for starting preconception counseling at puberty in girls with diabetes is feasible. Mother-daughter dyadic analyses can be important to explore

A teenage woman's sexual health practices may be influenced by her mother's experience. We evaluated whether there is an intergenerational tendency for induced abortion between mothers and their teenage daughters. We conducted a retrospective population-based cohort study involving daughters born in Ontario between 1992 and 1999. We evaluated the daughters' data for induced abortions between age 12 years and their 20th birthday. We assessed each mother's history of induced abortion for the period from 4 years before her daughter's birth to 12 years after (i.e., when her daughter turned 12 years of age). We used Cox proportional hazard models to estimate a daughter's risk of having an induced abortion in relation to the mother's history of the same procedure. We adjusted hazard ratios (HRs) for maternal age and world region of origin, mental or physical health problems in the daughter, mother- daughter cohabitation, neighbourhood-level rate of teen induced abortion, rural or urban residence, and income quintile. A total of 431 623 daughters were included in the analysis. The cumulative probability of teen induced abortion was 10.1% (95% confidence interval [CI] 9.8%-10.4%) among daughters whose mother had an induced abortion, and 4.2% (95% CI 4.1%-4.3%) among daughters whose mother had no induced abortion, for an adjusted HR of 1.94 (95% CI 1.86-2.01). The adjusted HR of a teenaged daughter having an induced abortion in relation to number of maternal induced abortions was 1.77 (95% CI 1.69-1.85) with 1 maternal abortion, 2.04 (95% CI 1.91-2.18) with 2 maternal abortions, 2.39 (95% CI 2.19-2.62) with 3 maternal abortions and 2.54 (95% CI 2.33-2.77) with 4 or more maternal abortions, relative to none. We found that the risk of teen induced abortion was higher among daughters whose mother had had an induced abortion. Future research should explore the mechanisms for intergenerational induced abortion. © 2018 Joule Inc. or its licensors.

Mothers are a key influence on adolescent girls' body image. This study aimed to improve understanding of mothers' and daughters' preferences for content in body image interventions designed to assist mothers to promote positive body image among their daughters. British mother-daughter dyads (N=190) viewed descriptions of five evidence-based influences on body image (family, friends, and relationships; appearance-based teasing; media and celebrities; appearance conversations; body acceptance and care). Mothers and daughters each selected the two most important influences to learn about in these interventions. Overall, both mothers and daughters most frequently opted for family, friends, and relationships and body acceptance and care, whereas media and celebrities was their least preferred topic. While the overall sample of mothers and daughters agreed on preferences, Fisher's exact tests showed that within-dyad agreement was low. Recommendations for improving parent and child engagement with, and effectiveness of, child body image interventions delivered to parents are discussed. Copyright © 2016 Elsevier Ltd.

To examine bias and sexual harassment experiences of physician mothers and their physician daughters; correlations of these experiences with career satisfaction, stress at work, stress at home, and percentage of women in specialty; and influences of the mother on her daughter's experiences. A convenience sample of 214 families with mother and daughter physicians was sent a 56-item survey that included questions on bias and sexual harassment experiences. Statistical comparisons were made within 136 dyads where both mother and daughter returned the questionnaire. Eighty-four percent of mothers and 87% of daughters responded. Mothers and daughters reported similarly high rates and severity of sexual harassment before medical school, while in residency/fellowship, while in practice/work setting, and by teachers and supervisors. Daughters reported higher rates of harassment during medical school and by patients, mothers by colleagues. Gender and racial/ethnic discrimination was lower for daughters compared with their mothers, but gender discrimination was still substantial. Compared with other daughters, daughters who experienced discrimination or sexual harassment reported lower career satisfaction and more stress at work and at home and worked in specialties with fewer women. Gender discrimination and sexual harassment remain entrenched in medical education and professional workplaces. Maternal role models and mentors were not as protective as anticipated. Leadership of medical institutions and professional associations must deal more effectively with persistent discrimination and harassment or risk the loss of future leaders.

• Background and Aims Drought damages cultivated C3, C4 and CAM plants in the semi-arid lands of central Mexico. Drought damage to Opuntia is common when mother cladodes, planted during the dry spring season, develop young daughter cladodes that behave like C3 plants, with daytime stomatal opening and water loss. In contrast, wild Opuntia are less affected because daughter cladodes do not develop on them under extreme drought conditions. The main objective of this work is to evaluate the effects of the number of daughter cladodes on gas exchange parameters of mother cladodes of Opuntia ficus-indica exposed to varying soil water contents. • Methods Rates of net CO2 uptake, stomatal conductance, intercellular CO2 concentration, chlorophyll content and relative water content were measured in mature mother cladodes with a variable number of daughter cladodes growing in spring under dry and wet conditions. • Key Results Daily carbon gain by mother cladodes was reduced as the number of daughter cladodes increased to eight, especially during drought. This was accompanied by decreased mother cladode relative water content, suggesting movement of water from mother to daughter cladodes. CO2 assimilation was most affected in phase IV of CAM (late afternoon net CO2 uptake) by the combined effects of daughter cladodes and drought. Rainfall raised the soil water content, decreasing the effects of daughter cladodes on net CO2 uptake by mother cladodes. • Conclusions Daughter cladodes significantly hasten the effects of drought on mother cladodes by competition for the water supply and thus decrease daily carbon gain by mother cladodes, mainly by inhibiting phase IV of CAM.

Although opportunities to vaccinate against human papillomavirus (HPV) are available, vaccination rates in Puerto Rico remain low. Communication between parents and adolescents about sexual topics may influence decisions about HPV vaccination uptake, particularly among young women; yet, few studies have addressed this issue. This qualitative study explored Puerto Rican mothers' and daughters' communication on sex-related topics, and HPV, including the HPV vaccine. Thirty participants, including 9 mothers and 21 daughters, participated in seven focus groups. Participants were divided into groups of mothers and daughters, and further stratified by vaccination status. Transcripts were analyzed using a modified grounded theory approach to identify emergent themes. Focus group data revealed four main themes: (1) limited parent-daughter communication about sex-related topics; (2) daughters' discomfort discussing sex-related topics with their parents; (3) parental focus on abstinence; and, (4) limited parent-daughter communication about HPV and the HPV vaccine. Although daughters in this study struggled with feelings of embarrassment, invasion of privacy, encouragement of abstinence, and the fear of parents' reaction to them being sexually active prior to marriage, they also recognized the need to increase the parent-daughter communication about sex-related topics including HPV and the HPV vaccine. Educational efforts should target both daughters and parents to increase communication skills and self-efficacy and to enable them to discuss sexual health in open and nonjudgmental conversations.

During cell division in the yeast Saccharomyces cerevisiae mother cells produce buds (daughter cells) which are smaller and have longer cell cycles. We performed experiments to compare the lengths of cell cycle phases in mothers and daughters. As anticipated from earlier indirect observations, the longer cell cycle time of daughter cells is accounted for by a longer G1 interval. The S-phase and the G2-phase are of the same duration in mother and daughter cells. An analysis of five isogenic strains shows that cell cycle phase lengths are independent of cell ploidy and mating type.

The theoretical and practical aspects of the use of radioactive daughters originated from the decay of longer-lived radioactive mothers in parametric activation analysis, when the ratio: mother half-life to daughter half-life is less than 10, are discussed. The mother-daughter relationships: 47 Ca/ 47 Sc; 95 Zr/ 95 Nb; 140 Ba/ 140 La; 99 Mo/ 99m Tc and 115 Cd/ 115m In are selected as models for the study. The cases when the radionuclide of interest is formed through both direct and indirect routes are also analyzed. As illustrative example, the direct reaction and the reaction chain: 47 Ti(n,p) 47 Sc/ 46 Ca(n,γ) 47 Ca(β - ) 47 Sc are evaluated with respect to the determination of the elements involved and their reciprocal interferences.

Papanicolaou (Pap) testing rates among Chinese women remain low compared with their Caucasian counterparts despite extensive efforts to raise awareness of the importance of regular screening. We examined three potential predictors of Pap testing behaviour in Chinese women: acculturation, cervical cancer screening belief accuracy, and intergenerational transmission. Caucasian (n = 78) and Chinese (n = 93) female university students and their mothers completed questionnaires concerning acculturation, Pap testing beliefs, and behaviours. Ethnic group comparisons revealed that Chinese daughters and mothers had lower Pap testing rates and less accurate beliefs regarding cervical cancer screening. Among women who had had at least one Pap test, there was no ethnic difference in the proportion of women who adhered to the recommended screening frequency. Among the Chinese women, lower heritage acculturation was correlated with higher cancer screening belief accuracy in both the daughters and their mothers. Maternal Pap testing behaviour was predicted by level of cancer screening belief accuracy, whereas daughters' Pap testing behaviour was predicted by previous experience of sexual intercourse and heritage acculturation. No intergenerational transmission of Pap testing beliefs or behaviours was found. The accuracy of cancer screening beliefs, level of acculturation and experience of sexual intercourse may be predictors of Pap testing behaviour in Chinese women. Contrary to our prediction, we found no support for intergenerational transmission, suggesting that Pap testing beliefs and behaviours of Chinese women are independent of the beliefs and behaviours of their mothers.

Conflict management of mothers and daughters belonging to individualistic and collectivistic cultural backgrounds: a comparative study.

1999-12-01

Research on the mother-daughter relationship during adolescence is mostly conducted in Western and European cultures where individualism is stressed. To examine ethnic/cultural differences and similarities in this relationship, 80 dyads of British (white) and Pakistani mothers and their adolescent daughters were studied. On the basis of the theories of cultural variability dimension and conflict face negotiation, it was hypothesized that mothers and daughters from the two cultures would use different styles of handling disagreements/conflicts. That is, Pakistani mothers and daughters would use an avoiding style, whereas British mothers and daughters would use either a dominating or compromising style, to a greater degree. It was also argued that Pakistani daughters and mothers will express more intimacy and relational harmony, will exhibit greater connectedness and mutuality and demonstrate lesser individuality and self-assertion compared to their British counterparts. However, it appeared that both the groups used an avoiding style equally, although the British group used a dominating style more than Pakistani group. As hypothesized, Pakistani mothers and daughters expressed more intimacy, relational harmony, connectedness and mutuality and lesser individuality than British mothers and daughters.

Korean adolescent girls are unprepared for cervical cancer prevention due to the lack of a mandatory policy regarding human papilloma virus (HPV) vaccination and school health education regarding cervical cancer. The aim of this study was to determine how aware mothers are about cervical cancer prevention in their adolescent daughters, with a view to developing strategies for expanding primary cervical cancer prevention for adolescent girls through the mothers' involvement. A qualitative design was employed. Nine mothers with adolescent daughters participated in this study and were interviewed using open-ended questions. The themes were extracted by content analysis. A general living area in Seoul, South Korea. The snowball method was used to select mothers. Five themes emerged. In general, the mothers' awareness of cervical cancer was not clear, and they exhibited a lack of awareness of the importance of having a regular Papanicolaou screening test. The mothers recognised that they were role models for their daughters, and realised and accepted the necessity of educating their daughters regarding cervical cancer; however, they perceived barriers related to the prevention of cervical cancer in their daughters. The mothers recommended enforcing sex education in schools and the provision of financial support for HPV vaccination. The mothers' awareness and preparedness with respect to the prevention of cervical cancer in their adolescent daughters were low and inadequate. Mothers should be informed and motivated to play a role in the education of their daughters regarding cervical cancer prevention. Strategies for disseminating information regarding early cervical cancer prevention for adolescent girls are recommended by communicating with both the girls and their mothers and providing them with education regarding cervical cancer prevention.

Poor body image is a public health issue. Mothers are a key influence on adolescent girls' body image. This study evaluated an accessible, scalable, low-intensity internet-based intervention delivered to mothers (Dove Self Esteem Project Website for Parents) on mothers' and their adolescent daughters' body image and psychosocial well-being. British mother-daughter dyads (N = 235) participated in a cluster randomized controlled trial (assessment-only control; mothers viewed the website without structured guidance [website-unstructured]; mothers viewed the website via a tailored pathway [website-tailored]). Dyads completed standardized self-report measures of body image, related risk factors, and psychosocial outcomes at baseline, 2 weeks post-exposure, 6-week, and 12-month follow-up. Dyadic models showed that relative to the control, mothers who viewed the website reported significantly higher self-esteem at post-exposure (website-tailored), higher weight esteem at 6-week follow-up (website-tailored), lower negative affect at 12-month follow-up (website-tailored), engaged in more self-reported conversations with their daughters about body image at post-exposure and 6-week follow-up, and were 3-4.66 times more likely to report seeking additional support for body image issues at post-exposure (website-tailored), 6-week, and 12-month (website-tailored) follow-up. Daughters whose mothers viewed the website had higher self-esteem and reduced negative affect at 6-week follow-up. There were no differences on daughters' body image, and risk factors among mothers or daughters, at post-exposure or follow-up. Tailoring website content appeared beneficial. This intervention offers a promising 'first-step' toward improving psychosocial well-being among mothers and daughters. In order to further optimize the intervention, future research to improve body image-related outcomes and to understand mechanisms for change would be beneficial.

Askelson, Natoshia M; Campo, Shelly; Smith, Sandi

2012-01-01

Parent-child communication about sex has been shown to delay sexual activity and increase contraceptive and condom use. The influence of authoritative parenting style and mothers' perception of daughters' risk on communication about sex was examined in this study. Mothers in a random sample (n=283) with daughters aged 9-15 years were mailed surveys asking about communication with their daughters regarding 11 sex-related topics. Multivariate linear regression was used to assess the influence of authoritative parenting style and mothers' perceptions of risk on the number of topics communicated about and age of the daughter at time of communication for a variety of sexual health communication topics. Authoritative parenting style was related to the number of topics communicated about and was a predictor of age of daughter at the time of communication about sexual intercourse, menstruation, dating/relationships, sexually transmitted diseases (STDs), HIV/AIDS, alcohol, contraceptives, and abstinence, while perceptions of risk were not significant influencers of age at the time of communication for any topics. This research points to the importance of parenting style in determining the timing of parent-child communication about sexual and other risk behaviors.

Are daughters' childbearing intentions related to their mothers' socio-economic status?

Directory of Open Access Journals (Sweden)

Maria Rita Testa

2016-09-01

Full Text Available Background: Unlike actual fertility, fertility intentions are often found to be positively correlated with education. The literature explaining this paradox is scarce. Objective: We aim to fill the gap in the existing scientific literature by searching for the main factors that influence highly educated women to plan a larger family size. Methods: Using the first wave of the Generations and Gender Survey for four countries (Austria, Bulgaria, Italy, and Norway, we analyse the relationship between mother's socio-economic status and daughter's fertility intentions, controlling for daughter's socio-economic status and sibship size. Zero-inflated Poisson regression models are employed to estimate the predictors of women's additionally intended number of children. Results: We find that the effect of family of origin is exerted mainly through sibship size among childless daughters: Daughters with more siblings intend to have more children. After the transition to parenthood, the effect of family of origin is exerted mainly through the mother's level of education: Daughters with highly educated mothers intend to have more children. Conclusions: The empirical results suggest that the positive link between births intentions and level of education might not merely be an artefact generated by the design of cross-sectional surveys but the outcome of a better socio-economic status that allows forming positive reproductive plans. Contribution: The positive role of mother's socio-economic status on daughter's fertility decision-making offers a valuable interpretation of the positive link between education and fertility intentions which goes beyond the alternative explanations referring to self-selection, partner effect, or time squeeze, and needs to be confirmed by further research.

Concordant Patterns of Brain Structure in Mothers with Recurrent Depression and Their Never-Depressed Daughters.

2016-01-01

A growing body of research has demonstrated that having a mother with a history of major depressive disorder (MDD) is one of the strongest predictors of depression in adolescent offspring. Few studies, however, have assessed neural markers of this increased risk for depression, or examined whether risk-related anomalies in adolescents at maternal risk for depression are related to neural abnormalities in their depressed mothers. We addressed these questions by examining concordance in brain structure in two groups of participants: mothers with a history of depression and their never-depressed daughters, and never-depressed mothers and their never-depressed daughters. We scanned mothers with (remitted; RMD) and without (control; CTL) a history of recurrent episodes of depression and their never-depressed daughters, computed cortical gray matter thickness, and tested whether mothers' thickness predicted daughters' thickness. Both RMD mothers and their high-risk daughters exhibited focal areas of thinner cortical gray matter compared with their CTL/low-risk counterparts. Importantly, the extent of thickness anomalies in RMD mothers predicted analogous abnormalities in their daughters; this pattern was not present in CTL/low-risk dyads. We identified neuroanatomical risk factors that may underlie the intergenerational transmission of risk for MDD. Our findings suggest that there is concordance in brain structure in dyads that is affected by maternal depression, and that the location, direction, and extent of neural anomalies in high-risk offspring mirror those of their recurrent depressed mothers. © 2016 S.

2018-04-01

African American girls experience disparate rates of pregnancy and acquisition of sexually transmitted infections, including human immunodeficiency virus, when compared to their non-Hispanic White counterparts. Among African American girls, current pregnancy rates are equal to the national crisis levels of teen pregnancy reported in 1990. This qualitative elicitation study was conducted to gain insight into the ways in which African American mothers and their daughters, between the ages of 9 and 14, communicate about sexual health. Early sexual health communication between mothers and daughters is known to enhance the sexual health outcomes of girls. A series of four focus groups and three in-depth interviews were conducted between July and September 2014. The theory of planned behavior was the organizing framework. Theoretical constructs that guided this study were attitudes, perceived behavioral control, and subjective norms. Results showed that what African American women share with their daughters about sexual health stems from their personal faith, values, and experiences. Findings from this study can inform interventions to provide support for this understudied population. Moreover, there are implications for health-care providers, particularly school nurses, who are in an ideal position to help increase mothers' self-efficacy to engage in sexual health conversations with their young daughters.

2011-11-01

The present study surveyed mothers with daughters (N = 386) to investigate how mothers' concern about their daughters' breast cancer risk influenced intentions to engage in preventive behaviors. Using protection motivation theory as a framework, self-efficacy, response efficacy, and level of concern were posited to influence protective behavioral intention in distinct ways. Results from regression analyses indicate that self-efficacy, response efficacy, and mothers' concern are significant predictors of intentions to engage in preventive behaviors with daughters. In addition, a content analysis of mothers' open-ended reasons for their concern about their daughters' breast cancer risk yield a list of specific concerns and trends that vary by concern level and individual comment valence. The authors discuss implications for incorporating mothers' concerns into breast cancer prevention messages as a novel strategy for campaign designers.

Full Text Available Psychotherapeutic interventions that bring about differentiation, separation, individuation and autonomy in the mother-daughter relationship are recommended as treatment for eating disorders. With this goal in mind, a psychotherapy group for mothers was organized in an outpatient program for adolescents with eating disorders at a public institution, as one of the psychotherapeutic approaches in the multidisciplinary treatment of adolescent patients. Evidence suggests that this approach can be relevant and effective in the treatment of eating disorders.

From mothers to daughters: transgenerational food and diet communication in an underserved group.

2004-01-01

Studies show that young girls are highly influenced by their mothers' attitudes toward food and body image. To investigate the nature of the information about food that mothers transfer to their daughters, the researchers used focus groups comprising African American women. Results suggest that when educators work with low-income African American women, they should be cognizant of overeating from the perspectives of early food scarcity, reverence for the mother's authoritative role in the family and respect for cultural differences in body size norms. In addition, nutrition educators should counsel young mothers to understand the impact of their eating habits on their daughters.

The aim of the study was to explore and describe the strategies young women with type 1 diabetes used to manage life transitions. The paper describes one aspect of how guilt dynamic often operates between mothers and daughters and how the women managed the guilt dynamic to create stability in their lives. When a child is diagnosed with diabetes, major transitional changes occur in the relationships between the mother and her child. The changes affect the psychological and social aspects of their lives and have a major impact on how young women manage their diabetes. A guilt dynamic between mothers and young women with diabetes emerged as a major theme in a larger study that investigated how young women with diabetes managed life transitions. Although the literature indicates that mothers of chronically ill children experience guilt feelings towards their children, little research was identified that addressed the emotional dynamics between mothers and daughters with diabetes. Using grounded theory method, interviews were conducted with 20 women with type 1 diabetes and five mothers during 2002 and 2003. Constant comparative analysis was used to analyse the data and develop an in-depth understanding of the experience of living with diabetes during life transitions. The findings revealed that guilt feelings created a two-way dependency between mothers and their daughters with diabetes. The two-way dependency involved feelings of being a burden to each other, difficulty balancing responsibilities for diabetes management, difficulty relinquishing emotional and social dependency especially during life transitions. In addition, these issues were rarely discussed openly with each other or with health professionals. The findings provide additional information about the human experience of the mother-daughter relationship and the effect on coping with diabetes in the context of life transitions. Understanding the impact diabetes has on the emotional and social well being of

Full Text Available Abstract Background International studies suggest ethnic differences in obesity prevalence may be due, in part, to differences in body image and body size dissatisfaction between groups. Further, there is evidence to suggest that there is a familial resemblance in body image between mothers and their younger (preadolescent daughters. This research was therefore conducted to specifically identify the extent to which family status (presented as mother-daughter resemblance and ethnicity impact on body image attitudes and perceptions of South African mothers and their pre-adolescent daughters. Methods Mother-daughter dyads (n = 201, 31% black, 37% mixed ancestry and 32% white answered questions regarding their body image perception (the way they saw their body size status, their body image ideals, and body image attitudes (body size dissatisfaction in particular, presented as the Feel-Ideal Difference [FID] index score. Mothers' and daughters' body image results were compared within dyads and across ethnic groups using repeated measures of ANOVA. Results Overall, body image resemblances exist between South African mothers and their pre-adolescent daughters. Mothers and daughters chose similarly weighted silhouettes to represent their body size ideals (p = 0.308, regardless of their ethnicity or body mass index (BMI. The FID index scores were similar between mothers and their daughters only after the confounding effects of maternal BMI were removed (p = 0.685. The silhouettes chosen to represent thinness were also similar between mothers and their daughters (p = 0.960 regardless of ethnicity and maternal BMI. On the other hand, the silhouettes chosen to represent fatness were similar (p = 0.342 between mothers and their daughters, only after the confounding effects of maternal BMI were removed. Lastly, mothers and their daughters chose similarly weighted silhouettes as engendering feelings of beauty, respect and happiness (p = 0.813; p = 0.615 and p

BACKGROUND: A teenage woman’s sexual health practices may be influenced by her mother’s experience. We evaluated whether there is an intergenerational tendency for induced abortion between mothers and their teenage daughters. METHODS: We conducted a retrospective population-based cohort study involving daughters born in Ontario between 1992 and 1999. We evaluated the daughters’ data for induced abortions between age 12 years and their 20th birthday. We assessed each mother’s history of induced abortion for the period from 4 years before her daughter’s birth to 12 years after (i.e., when her daughter turned 12 years of age). We used Cox proportional hazard models to estimate a daughter’s risk of having an induced abortion in relation to the mother’s history of the same procedure. We adjusted hazard ratios (HRs) for maternal age and world region of origin, mental or physical health problems in the daughter, mother– daughter cohabitation, neighbourhood-level rate of teen induced abortion, rural or urban residence, and income quintile. RESULTS: A total of 431 623 daughters were included in the analysis. The cumulative probability of teen induced abortion was 10.1% (95% confidence interval [CI] 9.8%–10.4%) among daughters whose mother had an induced abortion, and 4.2% (95% CI 4.1%–4.3%) among daughters whose mother had no induced abortion, for an adjusted HR of 1.94 (95% CI 1.86–2.01). The adjusted HR of a teenaged daughter having an induced abortion in relation to number of maternal induced abortions was 1.77 (95% CI 1.69–1.85) with 1 maternal abortion, 2.04 (95% CI 1.91–2.18) with 2 maternal abortions, 2.39 (95% CI 2.19–2.62) with 3 maternal abortions and 2.54 (95% CI 2.33–2.77) with 4 or more maternal abortions, relative to none. INTERPRETATION: We found that the risk of teen induced abortion was higher among daughters whose mother had had an induced abortion. Future research should explore the mechanisms for intergenerational induced

A growing body of research is demonstrating concordance between mother and child diurnal cortisol production. In the context of maternal history of depression, intergenerational concordance of cortisol production could contribute to hypercortisolemia in children of depressed mothers, which has been shown to increase risk for MDD. The current study is the first to examine concordance in diurnal cortisol production between mothers with a history of depression and their never-depressed, but high-risk, children. We collected salivary cortisol across 2 days from mothers with (remitted; RMD) and without (CTL) a history of recurrent episodes of depression and their never-depressed daughters. As expected, RMD mothers and their daughters both exhibited higher cortisol production than did their CTL counterparts. Moreover, both across and within groups, mothers' and daughters' cortisol production were directly coupled. These findings suggest that there is an intergenerational concordance in cortisol dysregulation that may contribute to hypercortisolemia in girls at familial risk for depression.

If you consider that at some point in life 50% of sexually active women have had an infection with the human papilloma virus is indisputable that any attempt to reduce the prevalence worth undertaking it. The vaccine to prevent HIV infection has not enjoyed the same degree of acceptance than others, hence the interest in knowing some of the reasons that has not achieved universal vaccination. To examine human papillomavirus (HPV) vaccine acceptability among mothers with adolescents girls between 9 and 13 years old. The mothers were interrogated about HVP vaccine acceptability, reasons provided for acceptance or non-acceptance and if mothers know that vaccine is offered free for public health institutions We interview a 250 mothers with 281 daughters, 38 daughters have already received the vaccine. Eighty nine percent of the mothers reacted positively to the possibility of vaccinating theirs daughters. The reasons of vaccine non-acceptance were because not knowing enough about infection, mother felt that their daughters were not at risk for acquiring HVP infection, the vaccine is new and mothers unknown side effects. Thirty nine percent of the mothers want to know more about the vaccine safety, 21% about length protection duration and 16% concerning about if the vaccine is effective. Fifty seven per cent of the mothers know that Health Secretary offers vaccine free. Mothers whom have been vaccinated their daughters, had daughters with lower age (9.8 +/- 0.9 vs 10.8 +/- 1.3 years, p = 0.0001), were more frequently married (79 vs 51%, p = 0.002) and more likely to report that they had heard about VPH vaccine from some source (100 vs 66%, p = 0.0001) that mothers have not yet vaccinated their daughters. The acceptability of VPH vaccine was 89%. Continued health education and propaganda is needed to promote a better knowledge of VPH vaccine.

Neonatal jaundice is the commonest abnormal physical finding in the new born nursery and hemolytic disease of the newborn (HDN) among babies born to Rh negative mothers is the most formidable etiology. During last few decades considerable evolution has been observed in this entity secondary to development of several novel preventive, diagnostic and therapeutic modalities. To study the current trends in presentation, management and outcome of hyperbilirubinemia among newborns delivered to Rh negative mothers. This observational descriptive study with prospective data collection included one hundred live born term babies born to Rh negative mothers in our hospital. A predesigned proforma was used to record antenatal and postnatal data .Cord blood collected during delivery for assessment of bilirubin,hematocrit and direct coombs test.Serum bilirubin levels were estimated in babies with clinical jaundice and treated for the same if required.All babies were regularly followed up weekly for one month. Chi square test/Fisher Exact test and Student "t" test has been used to find the significant association of jaundice(incidence,treatment) and study characteristics. Out of 100 babies enrolled, 57 babies developed jaundice. Jaundice is 2.7 times more likely associated with babies born to multiparous Rh-ve mothers with p=0.017*. Jaundice is 3 times more likely associated with Rh+ve babies born to multiparous mothers with p=0.020*. Jaundice is 3.97 times more likely associated with Rh+ve babies born to multiparous mothers who have not received Anti-D with p=0.154. Treatment of jaundice is 2.75 times more likely in Rh+ve babies born to multiparous mothers who have not received Anti-D with p=0.162. Duration of phototherapy is significantly more in Rh+ve babies born to multiparous mothers who had not received Anti-D with p=0.0097*.Exchange transfusion was required in two babies. Although the incidence of Rh isoimmunization has declined dramatically over the years ,it is still an

This study examines the role of mother's health and socioeconomic status on daughter's self-rated health using data spanning three decades from the National Longitudinal Surveys of Mature Women and Young Women (N = 1,848 matched mother-daughter pairs; 1,201 White and 647 African American). Using nested growth curve models, we investigated whether mother's self-rated health affected the daughter's self-rated health and whether socioeconomic status mediated this relationship. Mother's health significantly influenced daughters' self-rated health, but the findings were mediated by mother's socioeconomic status. African American daughters reported lower self-rated health and experienced more decline over time compared with White daughters, accounting for mother's and daughter's covariates. Our findings reveal maternal health and resources as a significant predictor of daughters' self-rated health and confirm the role of socioeconomic status and racial disparities over time. © The Author(s) 2015.

Can Better Mother-Daughter Relations Reduce the Chance of a Suicide Attempt among Latinas?

2011-01-01

Full Text Available National surveys and other research on adolescent Latinas show that adolescent females have higher rates of suicidal ideation, planning, and attempts than other ethnic and racial minority youth. Internalizing behaviors and family conflicts are commonly associated with suicidality in research on adolescents. In the case of Latinas, we explore the connection between adolescent Hispanic cultural involvement, mother-adolescent mutuality, internalizing behaviors, and suicidality. This paper presents data from a study of 232 Latinas, some with a recent history of suicide attempts (n=122. The results show that higher adolescent Hispanic cultural involvement was associated with greater mother-daughter mutuality and thus led to reduction in the likelihood of suicide attempts. The relationship between mother-daughter mutuality and suicide attempts among Latinas is mediated by specific internalizing behaviors (withdrawn depressive. Our findings highlight the positive effect that Latino cultural values have in the relationship between Latina adolescent and their mothers and confirm the importance that internalizing behaviors and the mother-daughter relationship have for suicide attempters.

Teenage pregnancy-prevention interventions have fallen short in significantly decreasing risk of pregnancy for Thai populations. The "breaking the voice" ("rak luk khun tong pood") culture-appropriate teenage pregnancy-prevention program was developed using community-based research. Qualitative analyses of focus group data identified salient factors related to sexual communication and behavior. The integration of focus group results with theoretical constructs guided the development of an intervention to reduce risky sexual behavior by increasing communication between mothers and their adolescent daughters. A total of 157 mother-daughter dyads from congested areas in Bangkok participated in pilot testing of the intervention by the use of a survey. The findings indicated a significant increase in the frequency of and number of sexual risk communication (P assertiveness, and ability to decrease sexual risk among daughters (P < .05). "Breaking the voice" represents a female-focused and culturally-relevant intervention to combat teenage pregnancy. © 2018 John Wiley & Sons Australia, Ltd.

The aim of this study, carried out before the beginning of human papillomavirus (HPV) vaccinations as a National Immunization Program (NIP) in Korea in 2016, is to assess the ranges of perceptions and personal experience and their influences on attitudes regarding HPV vaccinations of children, among mothers of adolescent (9-14 years of age) daughters in Korea. From November 2015 to February 2016, we distributed a written questionnaire to mothers who had daughters aged 9-14 years. The questionnaire consisted of several questions, related to knowledge of HPV, personal experiences of HPV vaccination, and attitudes toward HPV vaccinations of their adolescent daughters. Of the 260 questionnaires distributed, 140 participants returned answered ones. And although only 51% of participants were aware that cervical cancer is highly related with HPV infection, 70% said they were willing to vaccinate their daughters, showing that awareness does not coincide with intention to vaccinate. Among the participants showing negative attitudes, 50% were concerned about the vaccination side effects. The more the participants' pre-knowledge about HPV infection, and about the relationship of HPV to cervical cancer, the more positive their attitudes (P = 0.002, P mothers with negative attitudes toward vaccinating their adolescent daughters rose as well. Thus, the provision of correct education by health care providers and accurate information through active advertising may play an important role in increasing the vaccination rate among adolescent girls in Korea.

Centriole elimination is an essential process that occurs in female meiosis of metazoa to reset centriole number in the zygote at fertilization. How centrioles are eliminated remains poorly understood. Here we visualize the entire elimination process live in starfish oocytes. Using specific fluorescent markers, we demonstrate that the two older, mother centrioles are selectively removed from the oocyte by extrusion into polar bodies. We show that this requires specific positioning of the second meiotic spindle, achieved by dynein-driven transport, and anchorage of the mother centriole to the plasma membrane via mother-specific appendages. In contrast, the single daughter centriole remaining in the egg is eliminated before the first embryonic cleavage. We demonstrate that these distinct elimination mechanisms are necessary because if mother centrioles are artificially retained, they cannot be inactivated, resulting in multipolar zygotic spindles. Thus, our findings reveal a dual mechanism to eliminate centrioles: mothers are physically removed, whereas daughters are eliminated in the cytoplasm, preparing the egg for fertilization. © 2016 Borrego-Pinto et al.

The cervical cancer disparity continues to exist and has widened between Black and non-Hispanic White women. Human Papillomavirus (HPV) vaccines could potentially reduce this disparity, yet remain underused among Black female adolescents. We investigated psychosocial and cultural factors associated with Black mothers' intentions to vaccinate their daughters against HPV, and explored views toward a HPV vaccine mandate. In this quantitative dominant, mixed methods study, cross sectional surveys (n=237) and follow-up semi-structured interviews (n=9) were conducted with Black mothers of daughters. A 2-step logistic regression determined factors associated with Black mothers' intention. Thematic content analysis determined emerging themes. Perceived susceptibility (p=.044), perceived barriers (pHPV vaccination intentions. Follow-up interviews provided insight into factors influencing mothers' intentions. Mothers with low intentions did not perceive their daughter to be currently sexually active or in near future, thus, not at HPV risk. Pediatricians were identified as the most influential person on maternal decision-making if there was a pre-existing relationship. However, many mothers had not received a pediatricians' recommendation for their daughters. Barriers influencing mother's decision-making include knowledge, daughters' age, and mistrust in pharmaceutical companies and physicians. Mothers were not in favor of the HPV vaccine mandate. Findings demonstrate the need to develop and evaluate physician-led interventions on HPV and vaccine importance, and engage these mothers in intervention development to build trust between physicians, researchers, and Black mothers to improve HPV vaccine uptake in Black female adolescents.

2014-06-01

Full Text Available Objective: Revealing the experience of mothers when massaging their children to know the phenomenon in the context of a mother-child healthy development. Method: This is a qualitative study with a phenomenological approach carried out with 11 women who massaged their children and answered the guiding question: What did the experience of massaging your child mean to you? Results: The experience of massaging their children meant the development of their being a mother and of being a son/daughter, in addition to developing the attachment relationship between them. The massage can operationalize this integrality, become a tool of communication, stimulation and promotion of secure attachment, by promoting the loving interaction between mother and child. Conclusion: This practice should be considered as an option in the programs that promote the comprehensive health of the mother and child.

Much of the research on African-Americans' HPV vaccine acceptance has largely focused on racial/ethnic differences related to cognitive, socio-economical, and structural factors that contribute to differences in HPV vaccine acceptance and completion. A growing body of literature suggest that cultural factors, such as mistrust of healthcare providers (HCPs) and the healthcare system, religion, and social norms related to appropriate sexual behaviors, also plays a prominent role in their HPV vaccine acceptance. However, these studies were limited in their use of theoretical approaches necessary to conceptualize and operationalize culture. To explore the influence of culture on African-American mothers' and daughters' HPV vaccine acceptance using the PEN-3, a culturally-centered conceptual framework. Grounded theory techniques were used to explore cultural factors that influenced the acceptance of the HPV vaccine among African-American mothers (n = 28) and their daughters (n = 34). Positive attitudes towards vaccination stemmed from beliefs that the HPV vaccine has cancer prevention benefits and that vaccinations in general protected against infectious diseases. Negative attitudes stemmed from beliefs that the HPV vaccine was too new, not effective, daughters were too young, and that vaccines were not a one-size-fits-all intervention. Majority of mothers and daughters indicated that their religious doctrine did not impede their HPV vaccination decisions. For a few mothers, religious beliefs could not be separated from their HPV vaccination decisions and ultimately deterred HPV vaccine acceptance. HCP recommendations were valued however mothers were often dissatisfied with the detail of information communicated. Support networks provided both positive and negative types of social support to mothers and daughters. The media highlighted the cancer prevention benefits of the HPV vaccine and unintentionally communicated negative information of the HPV vaccine

2017-06-01

In budding yeast, a mother cell can produce a finite number of daughter cells over its life. The accumulation of a variety of types of damaged components has an impact on the aging process. Asymmetrical inheritance during cell division causes these aberrant intracellular constituents to be retained in mother cells and prevents them from segregating to daughter cells. However, the understanding of asymmetrical inheritance of individual proteins that are damaged or old age, and their relevance to the aging process, has been limited. The aim of this study is to propose a proteomics strategy for asymmetrical inheritance of preexisting proteins between mother and daughter cells. During synchronous culture for one generation, newly synthesized proteins were labeled with stable isotope amino acids to discriminate preexisting proteins originally expressed in mother cells, followed by separation of mother and daughter cells using a conventional method based on biotin labeling. Isotope incorporation ratios for individual proteins were quantified using mass spectrometry. We successfully identified 21 proteins whose preexisting versions were asymmetrically inherited in mother cells, including plasma membrane transporter involved in the aging process and organelle-anchoring proteins related to the stress response to misfolded proteins. Thus, our approach would be useful for making catalog of asymmetrically inherited proteins. © 2017 Molecular Biology Society of Japan and John Wiley & Sons Australia, Ltd.

Selective interactions among Rh, ABO, and sex ratio of newborns.

Valenzuela, C Y; Walton, R

1985-01-01

The hypothesis that the Rh and ABO blood systems behave like the HLA system in relation to mother-conception tolerance-rejection mechanisms was tested in 25,501 mother-infant pairs. According to this hypothesis, heterozygotes carrying a paternal gene that is not present in their mothers should be better tolerated than homozygotes. Significantly more BO infants born to AO mothers. AO infants born to BO mothers, Rh(+) heterozygotes born to Rh(-) mothers, and less significantly AO infants born to OO mothers confirm the hypothesis. Fewer homozygotes occurred in Rh(-) infants born to Rh(+) mothers and in O infants born to non-O mothers. Deviations from the Hardy-Weinberg equilibrium found in the ABO system were modified by the Rh and sex of the infant. These data strongly support the hypothesis that at least two feto-maternal systems influence the destiny of pregnancies: the classical known incompatibility system which operates late in pregnancy and a new one which is based on the induction of maternal tolerance early in pregnancy: maternal tolerance seems to be better elicited by heterozygous eggs or embryos carrying a gene not present in the mother. The data also support the hypothesis that the sex ratio is influenced by feto-maternal tolerance-rejection mechanisms associated with the ABO and Rh systems.

Caregiving decision making by older mothers and adult children: process and expected outcome.

Cicirelli, Victor G

2006-06-01

Dyadic caregiving decision making was studied in 30 mother-son and 29 mother-daughter pairs (mother's age=65-94 years) who responded to a vignette depicting a caregiving decision situation. The observed decision-making process of mother-child pairs was largely naturalistic, with few alternatives proposed and quick convergence to a decision followed by a postdecision justification; a degree of more rational decision making was seen in some pairs. Among significant findings, adult children, especially sons, dominated the decision process, doing more talking and introducing more alternatives than did their mothers, who played a more subordinate role. Mother-son pairs expected more negative outcomes and greater regrets regarding their decisions than mother-daughter pairs. Closeness of the parent-child relationship influenced the decision-making process, expected outcomes, and regrets. Copyright (c) 2006 APA, all rights reserved.

Associations of eating behaviors and psychological profile between mothers and daughters with eating disorders exist, but it is important to dissect the influence of the mother in each specific disorder since all eating disorders must be seen or treated not as one entity. The aim of the present study was to evaluate the association of eating behavior and psychological profile between mothers and daughters with different eating disorders and a control group. The study group included young girls with anorexia nervosa (AN, n = 30), bulimia nervosa (BN, n = 30), binge eating disorder (BED, n = 19), and a control group of women (Non-ED, n = 54) together with their mothers. BMI was calculated for dyads and Eating Disorder Inventory, Beck Depression Inventory, Beck Anxiety Inventory, Toronto Alexithymia Scale and Three-Factor Eating Questionnaire were applied. The differences between dyads were tested by Student's t test and Pearson's correlation was used to study the association between BMI, variables of eating behavior and psychological profile in each dyad. The study found significant inverse correlations between the AN dyad; some correlations between the BN dyad, and the highest positive correlations exist in BED dyad, especially in eating behavior. Finally, between the control dyads, low but significant correlations were found in the majority of cases. The study concluded that the associations between mothers and daughters with distinct eating disorders varied depending on the specific diagnosis of the daughter, indicating it is necessary to analyze them individually, given that there may be different implications for treatment.

An important proactive factor for the continuation of female genital mutilation (FGM) is tradition and customs inherited in the family from mothers to daughters. Therefore, the aim of this study was to determine mothers' factors associated with the occurrence of FGM among their daughters. The datasets from the Iraq Multiple Indicator Cluster Survey 2011, on 5,184 women aged 15 to 49 years having at least one daughter, was used. Multivariate analysis based on a binary logistic regression model was applied. Mothers' age (adjusted odds ratio [aOR] = 8.18 at ages 25-34 years, aOR = 22.64 at ages 35-44 years, and aOR = 29.78 at ages 45-49 years, compared to the age group 15-24 years), educational level (aOR = 0.52 for primary education, aOR = 0.26 for secondary education, and aOR = 0.03 for higher education compared to uneducated), employment status (aOR = 0.55 for women having office work compared with unemployed), FGM status (aOR = 27.44 for circumcised mothers compared to uncircumcised), the governorate of residence (aOR = 18.73 for Suleimaniya and aOR = 33.23 for Erbil compared with Dohuk), and the wealth index of the household (aOR = 0.55 for richest group compared to the poorest) were significantly associated with the occurrence of FGM in daughters. Strategies aimed at preventing this harmful practice in the Iraqi Kurdistan Region should include female education and empowerment.

2017-01-01

The aim of this study, carried out before the beginning of human papillomavirus (HPV) vaccinations as a National Immunization Program (NIP) in Korea in 2016, is to assess the ranges of perceptions and personal experience and their influences on attitudes regarding HPV vaccinations of children, among mothers of adolescent (9–14 years of age) daughters in Korea. From November 2015 to February 2016, we distributed a written questionnaire to mothers who had daughters aged 9–14 years. The questionnaire consisted of several questions, related to knowledge of HPV, personal experiences of HPV vaccination, and attitudes toward HPV vaccinations of their adolescent daughters. Of the 260 questionnaires distributed, 140 participants returned answered ones. And although only 51% of participants were aware that cervical cancer is highly related with HPV infection, 70% said they were willing to vaccinate their daughters, showing that awareness does not coincide with intention to vaccinate. Among the participants showing negative attitudes, 50% were concerned about the vaccination side effects. The more the participants’ pre-knowledge about HPV infection, and about the relationship of HPV to cervical cancer, the more positive their attitudes (P = 0.002, P vaccinating their adolescent daughters rose as well. Thus, the provision of correct education by health care providers and accurate information through active advertising may play an important role in increasing the vaccination rate among adolescent girls in Korea.

Like Mother, Like Daughter?: Matrilineal Opposition in African American Mulatta Melodrama

Directory of Open Access Journals (Sweden)

Anna Pochmara

2017-10-01

Full Text Available The article juxtaposes representations of mothers and daughters in selected African American novels that feature near-white female protagonists: W. W. Brown’s Clotel, Or the President’s Daughter (1853, Frances E. W. Harper’s Iola Leroy (1892, Charles Chesnutt’s The House behind the Cedars (1900, and Pauline Hopkins’s Hagar’s Daughter (1902. It explores the matrilineal opposition through a formalist close analysis of the melodramatic poetics of the texts and examines the political significance of such aesthetic choices. The novels expose the American history of interracial relations through their foregrounding of the mulatta protagonists and numerous scenes of anagnorisis of their multiracial identities. Simultaneously, their “erotics of politics” rewards the choice of a black spouse and thus celebrates the emergence of the self-determined black community.

When Fairness Clashes with Personal Autonomy and Parental Authority: A Comparison of Daughters' and Mothers' Reasoning in Two Cultural Contexts in Turkey.

Science.gov (United States)

Acar, Melike

2017-01-01

The author examined religious and secular daughters' and mothers' reasoning about personal autonomy, maternal authority, and moral concepts in family decision-making situations in urban Turkey. Sixty-eight daughters and 34 mothers were individually interviewed about decision-making autonomy in general issues and hypothetical daughter-mother conflicts. Results indicated participants regardless of their family status and religious background assigned more decision-making autonomy to mothers when evaluating general issues. Analysis of controversial issues as hypothetical conflicts indicated that daughters and mothers do not hold unitary social judgments about the social world that were always consistent with the norms of their community and family status. There were some religious background differences in evaluations of some conflict stories as a function of whether they evaluated the choices as moral, conventional, personal, and prudential matters. Although secular and religious participants conceptualized daughters and mothers in relational terms rather than characterizing the relations and social issues by harmony, obedience to authority, and acceptance of norms findings suggested that secular women evaluated the hypothetical adolescent-mother conflicts more consistently when the issue entails violation of a moral principle such as justice, fairness, and well-being of the other.

The comparative analysis of the number of nucleoli in cells of the established HeLa-M line was carried out before and after exposure to mitomycin C in a concentration of 10 μg/ml for 2 h. Using time-lapse microscopy, nucleoli in mother and their respective daughter cells were computed. It has been shown that the average number of nucleoli per cell is generally higher in daughter cells than in mother cells, and a standard deviation, on the contrary, decreases. An average number of nucleoli in daughter cells, whose mother cells had been treated with mitomycin C, was higher than in corresponding cells of control group. The separate analysis has been performed for the cells having from 1 to 4 nucleoli. Nonrandom complete coincidence of the number of nucleoli in mather and daughter cells has been typicaly shown for about 1/7 of the total cell population. Mitomycin C reduces this value of about 1.5 times.

Budding yeast divides asymmetrically, giving rise to a mother cell that progressively ages and a daughter cell with full lifespan. It is generally assumed that mother cells retain damaged, lifespan limiting materials ("aging factors") through asymmetric division. However, the identity of these aging factors and the mechanisms through which they limit lifespan remain poorly understood. Using a flow cytometry-based, high-throughput approach, we quantified the asymmetric partitioning of the yeast proteome between mother and daughter cells during cell division, discovering 74 mother-enriched and 60 daughter-enriched proteins. While daughter-enriched proteins are biased toward those needed for bud construction and genome maintenance, mother-enriched proteins are biased towards those localized in the plasma membrane and vacuole. Deletion of 23 of the 74 mother-enriched proteins leads to lifespan extension, a fraction that is about six times that of the genes picked randomly from the genome. Among these lifespan-extending genes, three are involved in endosomal sorting/endosome to vacuole transport, and three are nitrogen source transporters. Tracking the dynamic expression of specific mother-enriched proteins revealed that their concentration steadily increases in the mother cells as they age, but is kept relatively low in the daughter cells via asymmetric distribution. Our results suggest that some mother-enriched proteins may increase to a concentration that becomes deleterious and lifespan-limiting in aged cells, possibly by upsetting homeostasis or leading to aberrant signaling. Our study provides a comprehensive resource for analyzing asymmetric cell division and aging in yeast, which should also be valuable for understanding similar phenomena in other organisms.

Full Text Available Abstract Background Mothers have a primary role in the prevention of cervical cancer in Korea. This study aimed to determine the awareness and health beliefs of mothers about preventing cervical cancer in their daughters, their intention to recommend the Pap test to their daughters, and the factors influencing this intention. Methods A cross-sectional survey design was employed, and the study enrolled mothers (n = 1,581 of pubescent girls aged 13 to 18 years who were living nationwide in Korea. The six health-beliefs variables related to preventing cervical cancer in their daughters, awareness of the importance of cervical cancer prevention methods, and the intention to recommend the Pap test to daughters were investigated. The impacts of these health beliefs of the mothers and the sociodemographic factors influencing their intention to recommend the Pap test to their daughters were assessed using multiple logistic regression analysis. Results Almost one-quarter (23.7 % of the mothers had talked about the Pap test, 69.2 % were intending to recommend the Pap test to their daughters, and 38.5 % considered that the Pap test could be necessary if their daughters became sexually active. The significant health beliefs influencing the intention to recommend the Pap test were the perceived barriers [odds ratio (OR = 1.47, 95 % confidence interval (95 % CI = 1.03–2.11] and benefits (OR = 2.25, 95 % CI = 1.55–3.25. The significant sociodemographic factors of mothers were their education (OR = 1.52, 95 % CI = 1.08–2.13, their experience of talking about the Pap test with their daughters (OR = 2.11, 95 % CI = 1.23–3.64, their regularity of undergoing the Pap test themselves (OR = 1.98, 95 % CI = 1.30–3.03, and their age when they first underwent the Pap test (OR = 1.60, 95 % CI = 1.43–0.82. Conclusions The mothers perceived HPV vaccination as the most important of the five methods

Fang, Lin; Schinke, Steven P; Cole, Kristin C A

2010-11-01

This study examined the efficacy and generalizability of a family-oriented, web-based substance use prevention program to young Asian-American adolescent girls. Between September and December 2007, a total of 108 Asian-American girls aged 10-14 years and their mothers were recruited through online advertisements and from community service agencies. Mother-daughter dyads were randomly assigned to an intervention arm or to a test-only control arm. After pretest measurement, intervention-arm dyads completed a 9-session web-based substance use prevention program. Guided by family interaction theory, the program aimed to improve girls' psychological states, strengthen substance use prevention skills, increase mother-daughter interactions, enhance maternal monitoring, and prevent girls' substance use. Study outcomes were assessed using generalized estimating equations. At posttest, relative to control-arm girls, intervention-arm girls showed less depressed mood; reported improved self-efficacy and refusal skills; had higher levels of mother-daughter closeness, mother-daughter communication, and maternal monitoring; and reported more family rules against substance use. Intervention-arm girls also reported fewer instances of alcohol, marijuana, and illicit prescription drug use, and expressed lower intentions to use substances in the future. A family-oriented, web-based substance use prevention program was efficacious in preventing substance use behavior among early Asian-American adolescent girls.

Prior studies have examined critical expressed emotion (EE-Crit) in mothers in the intergenerational transmission of depression. However, the potential moderating effect of maternal depression diagnostic status in relation to EE-Crit and youth depressive symptoms has yet to be determined. A total of N=121 biological mother/daughter dyads that differed in maternal depression diagnostic status were recruited for the present study: (1) currently depressed mothers (current depression, n=29); (2) formerly depressed mothers (past depression, n=39); and (3) mothers free from any psychiatric history (healthy controls, n=53). Mothers were administered structured clinical interviews and completed self-report measures of EE-Crit and psychopathology, and daughters self-reported depressive symptoms. Results indicated no significant group differences in EE-Crit; however, current maternal depression status moderated EE-Crit such that the magnitude of the relation between EE-Crit and adolescent depressive symptoms was significantly greater in daughters of currently depressed mothers. These findings highlight the importance of considering current maternal depression, rather than a history of maternal depression, in relation to EE-Crit and adolescent depressive symptoms, providing impetus for future investigations.

Daughters of HIV-positive women are often exposed to the same factors that placed their mothers at risk. This cross-sectional study (N = 176 dyads) examined HIV status, parent-teen sexual risk communication (PTSRC), and daughters' abstinence and condom use beliefs and intentions. Maternal HIV status was not associated with PTSRC. Path analyses show that maternal depression was associated with PTSRC behavioral and normative beliefs; relationship satisfaction was associated with PTSRC normative and control beliefs. Control beliefs were solely predictive of maternal PTSRC intention. PTSRC was associated with adolescent behavioral and normative beliefs. Abstinence beliefs were associated with abstinence intentions; condom beliefs were associated with condom use intentions. Relationship satisfaction was associated with adolescent control beliefs about both abstinence and condom use. There is a need for interventions that help HIV-positive mothers recognize their daughter's HIV risk and provide them with relationship building and parent process skills to help reduce these risks.

2016-01-01

Hereditary nephrogenic diabetes iInsipidus (HNDI) is an uncommon disorder due to a resistance to anti-diuretic hormone leading to a reduced urinary concentrating ability. The X-linked form is fully expressed in hemizygous male patients, but diabetes insipidus may also present in heterozygous females where it must be distinguished from autosomal and other secondary causes. We report a mother and daughter in the same family with HNDI due to a heterozygous deletion in exon 1 of the AVPR2 gene, not previously described in the literature. A 5-year-old girl was referred for investigation of polyuria and polydipsia. The patient had a water deprivation test elsewhere at the age of 3 that was inconclusive. A degree of water restriction was imposed leading to headaches. The thyroid, cortisol, renal, and calcium profiles were normal. Her mother showed similar symptoms that had not been previously investigated. AQP2 (Aquaporin) and initial AVPR2 gene sequencing had not identified a mutation, but subsequent quantitative polymerase chain reaction analysis revealed a heterozygous large exon 1 deletion of the AVPR2 gene. The same deletion was also found in the child's mother. The patient's symptoms have significantly improved on appropriate treatment. Further analysis revealed skewed X inactivation in mother and daughter.

The purpose of this study is to explore and describe Khmer mothers' understanding of HBV and HPV prevention as well as their perception of parenting on health and health education of their daughters in the US. The qualitative pilot study guided by the revised Network Episode Model and informed by ethnographic analysis and community-based purposive sampling method were used. Face-to-face audiotaped interviews with eight Khmer mothers were conducted by bilingual female middle-aged community health leaders who spoke Khmer. The findings revealed that Khmer mothers clearly lacked knowledge about HBV and HPV infection prevention and had difficulty understanding and educating their daughters about health behavior, especially on sex-related topics. The findings showed that histo-sociocultural factors are integrated with the individual factor, and these factors influenced the HBV and HPV knowledge and perspective of Khmer mothers' parenting. The study suggests that situation-specific conceptual and methodological approaches that take into account the uniqueness of the sociocultural context of CAs is a novel method for identifying factors that are significant in shaping the perception of Khmer mothers' health education related to HBV and HPV prevention among their daughters. The communication between mother and daughter about sex and the risk involved in contracting HBV and HPV has been limited, partly because it is seen as a "taboo subject" and partly because mothers think that schools educate their children regarding sexuality and health.

Wilson, Ellen K; Koo, Helen P

2010-12-14

In the United States, nearly half of high school students are sexually active, and adolescents experience high rates of unintended pregnancy and sexually transmitted diseases. Parents can have an important influence on their children's sexual behaviour, but many parents do not talk with their children about sexual topics. Research has shown significant differences in parent-child communication about sexual topics depending on the gender of both the parent and the child. Little is known, however, about the reasons for these gender differences. The purpose of this paper is to describe how factors associated with parent-child communication about sexual topics differ by gender. Data are from a nationwide online survey with 829 fathers and 1,113 mothers of children aged 10 to 14. For each of the four gender groups (fathers of sons, fathers of daughters, mothers of sons, mothers of daughters), we calculated the distribution of responses to questions assessing (1) parent-child communication about sex-related topics, and (2) factors associated with that communication. We used chi-square tests to determine whether the distributions differed and the false discovery rate control to reduce the likelihood of type I errors. With both sons and daughters, fathers communicated less about sexual topics than mothers did. Fathers also had lower levels of many characteristics that facilitate communication about sex (e.g., lower self-efficacy and lower expectations that talking to their children about sex would have positive outcomes). Compared with parents of sons, parents of daughters (both mothers and fathers) talked more about sexual topics, were more concerned about potential harmful consequences of sexual activity, and were more disapproving of their child having sex at an early age. Using a large national sample, this study confirms findings from previous studies showing gender differences in parent-child communication about sexual topics and identifies gender differences in

This study documents generational differences in the impact of acculturation related factors on anxiety and alcohol use behaviors between adult Latino mothers and adult daughters. Findings indicate that for mothers (n=144) and daughters (n=149), self-reported anxiety levels decreased from baseline to follow up (p=.001). For mothers at follow up (n=147), results indicate that affiliation to Latino culture is negatively associated with anxiety (p= .018). Conversely, employment and partner relationship stress are positively associated with anxiety (p = .05 and p = .016 respectively). In addition, self-reported anxiety is positively associated with alcohol intake (p = .002) and employment (p = .007). For daughters(n=149), partner relationship stressors, anxiety and alcohol intake decreased significantly from baseline to follow up at a p = .01, p = .01 , p = .05 respectively. In addition, for daughters at baseline (n=160), affiliation to U.S. culture is positively associated with self-reported anxiety (p = .01). Employment is negatively associated with alcohol consumption (p = .027). At follow up (n=152), daughters’ partner relationship stress is positively associated with self- reported anxiety (p = .049). Findings in this study can be used to develop culturally appropriate interventions, support groups and individual therapy sessions by taking into consideration generational differences among Latino women.

2015-06-01

The current study explored the multifaceted nature of the mother-adolescent coparental relationship with data from 167 Mexican-origin adolescent mothers and their own mothers at 10 months post childbirth. Profiles of mother-adolescent coparenting were created with latent profile analysis using adolescents' reports of three dimensions of coparenting (communication, involvement, and conflict). Four profiles were identified: (a) Harmonious Coparents (equal involvement, high communication, low conflict); (b) Harmonious-Adolescent Primary (adolescent is more involved than mother, high communication, low conflict); (c) Conflictual Coparents (equal involvement, high communication, high conflict); and (d) Conflictual-Adolescent Primary (adolescent is more involved than mother, moderate communication, high conflict). Families characterized by high mother-daughter conflict and psychological control prior to childbirth were more likely to belong in the Conflictual Coparents profile. In addition, adolescents' and mothers' depressive symptoms and parenting efficacy after childbirth were linked to profile membership, such that the Harmonious-Adolescent Primary profile reported the most positive adjustment patterns, whereas profiles with high coparental conflict (i.e., Conflictual Coparenting and Conflictual-Adolescent Primary profiles) showed the least positive adjustment patterns. Discussion considers the applied implications of identifying precursors to healthy and problematic mother-daughter coparenting for families of adolescent mothers in the early years of parenting. © 2014 Family Process Institute.

Daughters on Hunger Strike

Ann Wan-lih Chang

2008-03-01

Full Text Available This essay explores the embattled interactions between mothers and daughters in the stories by Edna O’Brien, Mary Lavin, Éilís Ní Dhuibhne and Mary Leland. This conflict involves an underlying distorted intimacy between women within a patriarchal Irish context. The daughter in the stories seeks to rebel against the ‘choking love’ of the tyrannical ‘patriarchal mother’ through a symbolic anorexia, in which the daughter rejects the mother’s food or the food associated with the mother. The mother is also shown to feel ambivalent and resistant towards the daughter’s attempt to break from her dependence upon the mother. The conflict and resistance between mothers and daughters in these stories can be evaluated against the framework of the patriarchal context in which women as mothers are silenced and made powerless in front of the ‘Father,’ and therefore, this resistance can be interpreted as a reaction to this patriarchal ideology and its framework in Irish society. The lost bond between older and younger women needs to be rediscovered and restored by a realisation of patriarchal ideology and furthermore, identification with female subjectivity. This identification between women seems to act as a source of redemption for women of different generations, which results in both liberating themselves from the patriarchal dogma.

This study documents generational differences in the impact of acculturation related factors on anxiety and alcohol use behaviors between adult Latino mothers and adult daughters. Findings indicate that for mothers (n = 144) and daughters (n = 149), self-reported anxiety levels decreased from baseline to follow up (p = 0.001). For mothers at follow up (n = 147), results indicate that affiliation to Latino culture is negatively associated with anxiety (p = 0.018). Conversely, employment and partner relationship stress are positively associated with anxiety (p = 0.05 and p = 0.016 respectively). In addition, self-reported anxiety is positively associated with alcohol intake (p = 0.002) and employment (p = 0.007). For daughters(n = 149), partner relationship stressors, anxiety and alcohol intake decreased significantly from baseline to follow up at a p = 0.01, p = 0.01, p = 0.05 respectively. In addition, for daughters at baseline (n = 160), affiliation to U.S. culture is positively associated with self-reported anxiety (p = 0.01). Employment is negatively associated with alcohol consumption (p = 0.027). At follow up (n = 152), daughters' partner relationship stress is positively associated with self- reported anxiety (p = 0.049). Findings in this study can be used to develop culturally appropriate interventions, support groups and individual therapy sessions by taking into consideration generational differences among Latino women.

The current study explored the multifaceted nature of the mother-adolescent coparental relationship with data from 167 Mexican-origin adolescent mothers and their own mothers at ten months post-childbirth. Profiles of mother-adolescent coparenting were created with latent profile analysis using adolescents’ reports of three dimensions of coparenting (communication, involvement and conflict). Four profiles were identified: (a) Harmonious Coparents (equal involvement, high communication, low conflict); (b) Harmonious-Adolescent Primary (adolescent is more involved than mother, high communication, low conflict); (c) Conflictual Coparents (equal involvement, high communication, high conflict); and (d) Conflictual-Adolescent Primary (adolescent is more involved than mother, moderate communication, high conflict). Families characterized by high mother-daughter conflict and psychological control prior to childbirth were more likely to belong in the Conflictual Coparents profile. In addition, adolescents’ and mothers’ depressive symptoms and parenting efficacy after childbirth were linked to profile membership, such that the Harmonious-Adolescent Primary profile reported the most positive adjustment patterns, whereas profiles with high coparental conflict (i.e., Conflictual Coparenting and Conflictual-Adolescent Primary profiles) showed the least positive adjustment patterns. Discussion considers the applied implications of identifying precursors to healthy and problematic mother-daughter coparenting for families of adolescent mothers in the early years of parenting.

Body mass index (BMI) is reportedly gender assortative (mother-daughter, father-son) in contemporary children. We investigated the corresponding transmission of waist circumference (WC) and its implications. We measured parental WC at baseline and WC, height, weight and para-umbilical skin-fold (USF) annually in their offspring from 5 to 15 years (n = 223 trios). Parents were deemed normal metabolic risk (NR) or high risk (HR) according to World Health Organization (WHO) cut-points for WC (mothers 80 cm, fathers 94 cm). The residual from WC adjusted for BMI (WC|BMI ) was used as a surrogate for excess intra-abdominal fat, and its association with insulin resistance (HOMA2-IR) was sought. WC and USF were both gender assortative, while WC|BMI was not. WC was greater by 1.62 cm (P mothers, and by 1.32 cm (P surrogate in this analysis) is unrelated to parental waist circumference, but metabolically harmful. © 2013 The Authors.

This paper presents the results of a 12-week single-sex, family-based physical activity intervention grounded in Social Cognitive Theory. Mother/daughter pairs and triads (n = 20) attended physical activity and classroom sessions twice weekly. Physiological data (VO2peak, height, and weight), psychological data (physical self-perception profile subscale scores), information about physical activity participation (PAP, d x wk(-1)) and qualitative impressions (QI) of the program were collected pre- and post-intervention. PAP and QI were also collected 6-months after completing the intervention. Although no significant increases in physical activity were reported, significant improvements in perceived sport competence, physical condition, and strength and muscularity were reported over time. The social cognitive theory, as used to plan this physical activity intervention, offered a promising theoretical perspective for facilitating improved physical self-perception in adolescent girls and their mothers.

The aim of this study is to examine knowledge and attitude as facilitators and barriers to the acceptance of HPV vaccination for adolescent girls by mothers and adolescent girls. A cross-sectional survey conducted in Hong Kong in January 2010. Adolescent girls aged 12-18, together with their mothers, were recruited to complete two separate questionnaires with similar questions. A total of 170 mother-adolescent girl dyads were recruited. When the daughters and mothers were compared, the mothers were found to be more aware of "the risk of becoming infected with HPV through early sexual intercourse," while more daughters than mothers knew that "the HPV virus cannot be cured with antibiotics." Significantly more daughters perceived that they had a "chance of being infected with HPV and getting cervical cancer without the vaccine," while more mothers were concerned that "vaccinating for HPV will cause a girl to be stigmatized as promiscuous" and thought that their "adolescent daughters are too young to receive the HPV vaccine." The major predictive factor for the acceptance of the HPV vaccine among mothers was "The HPV vaccine is safe" (OR = 10.126, 95% CI 2.47-41.54). Among daughters who accepted the vaccine, the predictive factor was "The HPV vaccine can prevent most HPV infections" (OR = 6.274, 95% CI 1.93-20.42). The findings provide healthcare professionals with a better understanding of the differences between mothers and adolescent girls in knowledge, attitude, and potential factors associated with acceptance of the HPV vaccine. Health professionals should promote the early prevention of HPV infection and eliminate the stigma surrounding HPV vaccination to increase its acceptance. The government should provide financial support for adolescent girls to receive the vaccination in school.

Human papillomavirus (HPV) is one of the most common sexually transmitted infections in sexually active adolescents and young women and has been implicated as a cause of the majority of cases of cervical cancer, which is the second most common cancer in women in Nigeria. HPV is preventable with the use of HPV vaccines. The objective of this study was to assess mothers' HPV knowledge and their willingness to vaccinate their adolescent daughters in Lagos, Nigeria. This study was a community-based, descriptive cross-sectional study carried out in July, 2012 in Shomolu Local Government Area (LGA) of Lagos State, Nigeria. Multistage sampling method was employed to select the 290 respondents who participated in the study. Structured, pretested, interviewer-administered questionnaires were used for data collection. Data was analyzed with Epi Info™ version 7. The study revealed low awareness of HPV (27.9%) and HPV vaccines (19.7%) among the mothers that participated. There was a high awareness for cervical cancer but little knowledge of its link to HPV. Awareness and utilization of HPV vaccines increased with increasing educational level (P knowledge about HPV and HPV vaccines, mothers were willing to vaccinate their daughters. We recommend improving mothers' knowledge by education and the possible inclusion of the vaccine in the national immunization schedule to eliminate the financial barrier.

Gestational diabetes mellitus (GDM) and low magnesium (Mg) intake and status are associated with an increased risk of type 2 diabetes. However, Mg homeostasis may be modified by GDM. We sought to determine if a history of GDM prospectively modifies associations between Mg and glycemic variables in mothers and their offspring. Plasma and dietary Mg, anthropometric, lifestyle and glycemic variables were assessed in mothers affected by GDM during 1989-1990, a comparative group of normoglycemic women, pregnant during the same time period, and the 15-year-old, nondiabetic daughters of affected and unaffected pregnancies (n = 332). Multivariate regression analyses evaluated the cross-sectional association between plasma and dietary Mg with glycemic variables in mothers and daughters. Plasma Mg was lower in mothers with a history of GDM in comparison to control mothers after adjustment for current type 2 diabetes, race and body mass index (0.90 ± 0.01 versus 0.96 ± 0.01 mmol/L; p = 0.002). Plasma Mg was significantly associated with insulin sensitivity and was inversely associated with fasting insulin in GDM mothers only (pmothers and offspring with a history of GDM.

The present study explores how parents' personality clusters relate to their eating disordered daughters' personality and psychopathology. Mothers and fathers were tested with the Temperament Character Inventory. Their daughters were assessed with the following: Temperament and Character Inventory, Eating Disorder Inventory-2, Symptom Checklist-90, Parental Bonding Instrument, Attachment Style Questionnaire, and Family Assessment Device. Daughters' personality traits and psychopathology scores were compared between clusters. Daughters' features were related to those of their parents. Explosive/adventurous mothers were found to relate to their daughters' borderline personality profile and more severe interoceptive awareness. Mothers' immaturity was correlated to their daughters' higher character immaturity, inadequacy, and depressive feelings. Fathers who were explosive/methodic correlated with their daughters' character immaturity, severe eating, and general psychopathology. Fathers' character immaturity only marginally related to their daughters' specific features. Both parents' temperament clusters and mothers' character clusters related to patients' personality and eating psychopathology. The cluster approach to personality-related dynamics of families with an individual affected by an eating disorder expands the knowledge on the relationship between parents' characteristics and daughters' illness, suggesting complex and unique relationships correlating parents' personality traits to their daughters' disorder.

We herein describe a family whose female members are all osteoporotic: a postmenopausal mother and her three premenopausal daughters. The mother aged 60 presented axial and peripheral fractures, and very low bone mineral density (BMD). She reported that her grandmother had suffered a hip fracture. The eldest daughter aged 30 suffered multiple vertebral fractures during pregnancy and lactation associated with very low BMD. In view of these observations, the other two daughters aged 29 and 27 years respectively were evaluated. BMD was found to be severely diminished according to densitometric values for osteoporosis established by WHO, but they had no history of bone fractures. Probably the strong genetic component in bone mass is responsible for the severely diminished BMD observed in all the women in this family, as well as the occurrence of bone fractures in two of them. To our knowledge, there are no similar reports in the literature. Our results evidence the importance of evaluating bone mass in the offspring of an individual presenting severe osteoporosis, in order to detect family members with low bone mass and at high risk of developing bone fractures.

Associations among mother-daughter attachment, mother and daughter substance abuse, and daughter’s sexual behavior under the influence of drugs and alcohol were investigated among 158 adult U.S. Latina daughters. Latina daughters were sampled from four mother–daughter dyad types: substance abusing mother and daughter, substance abusing mother only, substance abusing daughter only, and nonsubstance-abusing mother and daughter. Substance abusing daughters with substance abusing mothers, and daughters who were less strongly attached to their mothers, reported more sex under the influence of drugs. Age, marital status, substance abuse, and mother’s substance abuse all influenced the daughter’s sex under the influence of alcohol. An unexpected positive association between attachment and sex under the influence of alcohol was found for daughters who were more closely attached to a substance abusing mother. Implications for future research, and HIV/AIDS and drug prevention and treatment programs for Latinas are discussed. PMID:19399605

Although breast cancer prevention targets mostly women ages 40 and older, little is known about breast cancer prevention for young women and mother's advice. The purpose of this study was to examine breast cancer prevention knowledge, attitudes, and behaviors among college women and mother-daughter communication. Hispanic and non-Hispanic students at a southwestern university completed a breast cancer prevention survey with items for mother's advice, breast self-awareness and risk reduction knowledge, self-efficacy, susceptibility, family history, provider breast self-exam (BSE) recommendation, peer norms, BSE practice, and demographics. An openended item was also used to elicit types of mother's advice. Logistic regression was used to assess predictors for receiving mother's advice for breast cancer prevention and BSE practice. Self-reported data using a survey were obtained from 546 college women with a mean age of 23.3 (SD = 7.75). Nearly 36 % received mothers' advice and 55 % conducted BSE. Predictors for receiving mother's advice were age, self-efficacy, and family history of breast cancer. Predictors for BSE practice were mother's advice, age, self-efficacy, and provider BSE recommendation. Family history of breast cancer and knowledge were not significant predictors for BSE practice. Findings support the need for clinicians, community health educators, and mothers to provide breast cancer prevention education targeting college women.

Creating meaningful partnerships with community partners to address cancer disparities remain challenging and a work in progress. This paper examines what started as the traditional formation of an academic-community partnership and evolved well beyond the initial research tasks. We evaluate the partnership process, which includes assessments by the members of the Mother-Daughter Health Collaborative, focusing on how partnership involvement in the data analysis process contributed to a sense of ownership and urgency about providing cancer education. The work of partnership is on-going, fluid, and challenging.

2012-01-01

Prophylaxis of RhD negative mothers with anti-D immunoglobulin after childbirth is the most important procedure reducing the immunization of the mother and the risk of severe hemolytic disease of the newborn. In spite of this, anti-D antibodies having relevance to pregnancy are later detected in 1.8% of RhD negative mothers. Half of these cases could be prevented by routine anti-D prophylaxis given to the mothers during weeks 28 to 34 of pregnancy. Convincing evidence of the effectiveness of this measure has accumulated in the last few years, and application of the treatment is justified also in Finland.

The semi-conservative centrosome duplication in cycling cells gives rise to a centrosome composed of a mother and a newly formed daughter centriole. Both centrioles are regarded as equivalent in their ability to form new centrioles and their symmetric duplication is crucial for cell division homeostasis. Multiciliated cells do not use the archetypal duplication program and instead form more than a hundred centrioles that are required for the growth of motile cilia and the efficient propelling of physiological fluids. The majority of these new centrioles are thought to appear de novo, that is, independently from the centrosome, around electron-dense structures called deuterosomes. Their origin remains unknown. Using live imaging combined with correlative super-resolution light and electron microscopy, we show that all new centrioles derive from the pre-existing progenitor cell centrosome through multiple rounds of procentriole seeding. Moreover, we establish that only the daughter centrosomal centriole contributes to deuterosome formation, and thus to over ninety per cent of the final centriole population. This unexpected centriolar asymmetry grants new perspectives when studying cilia-related diseases and pathological centriole amplification observed in cycling cells and associated with microcephaly and cancer.

Guanylic nucleotide starvation affects Saccharomyces cerevisiae mother-daughter separation and may be a signal for entry into quiescence

Full Text Available Abstract Background Guanylic nucleotides are both macromolecules constituents and crucial regulators for a variety of cellular processes. Therefore, their intracellular concentration must be strictly controlled. Consistently both yeast and mammalian cells tightly correlate the transcription of genes encoding enzymes critical for guanylic nucleotides biosynthesis with the proliferation state of the cell population. Results To gain insight into the molecular relationships connecting intracellular guanylic nucleotide levels and cellular proliferation, we have studied the consequences of guanylic nucleotide limitation on Saccharomyces cerevisiae cell cycle progression. We first utilized mycophenolic acid, an immunosuppressive drug that specifically inhibits inosine monophosphate dehydrogenase, the enzyme catalyzing the first committed step in de novo GMP biosynthesis. To approach this system physiologically, we next developed yeast mutants for which the intracellular guanylic nucleotide pools can be modulated through changes of growth conditions. In both the pharmacological and genetic approaches, we found that guanylic nucleotide limitation generated a mother-daughter separation defect, characterized by cells with two unseparated daughters. We then showed that this separation defect resulted from cell wall perturbations but not from impaired cytokinesis. Importantly, cells with similar separation defects were found in a wild type untreated yeast population entering quiescence upon nutrient limitation. Conclusion Our results demonstrate that guanylic nucleotide limitation slows budding yeast cell cycle progression, with a severe pause in telophase. At the cellular level, guanylic nucleotide limitation causes the emergence of cells with two unseparated daughters. By fluorescence and electron microscopy, we demonstrate that this phenotype arises from defects in cell wall partition between mother and daughter cells. Because cells with two unseparated

In Emilia-Romagna, the Human Papillomavirus (HPV) vaccination campaign started in 2008 offering free vaccines for 1996 and 1997 cohorts. Systematic active invitation was implemented for the 1997 cohort. Our study aimed at measuring the impact of the active invitation campaign on HPV vaccine coverage and on coverage inequalities in 11-year-old girls. Second, we evaluated the effect of the HPV vaccination campaign on participation in cervical cancer screening by mothers of target girls. We collected information on vaccination status for girls residing in Reggio Emilia in 2008 and mothers' screening history, before and after the 2008 vaccination campaign. Log-binomial regression models were performed to estimate Relative Risk (RR) and 95% confidence intervals (CIs) of being vaccinated as regarded citizenship, siblings, mothers' education, marital status and screening history, stratified by birth cohort. We also calculated RR of receiving a Pap test after the vaccination campaign as regarded education, daughter's cohort and mothers' decision to have their daughter vaccinated. Interaction between education and cohort in mothers overdue for Pap testing was calculated. Vaccination coverage was 46.3% for the uninvited cohort (1046/2260) and 77.9% for the invited cohort (1798/2307). In the uninvited cohort, daughters' vaccination showed association with mothers' education (8 to 11 years of education vs. graduated mothers, RR 1.61 95% CI 1.14-2.28), citizenship (foreigners vs. Italians, RR 0.45 95% CI 0.37-0.56) and screening history (regular vs. non-participant; RR 1.72 95% CI 1.26-2.36). In the invited cohort, only a slight association with screening history persisted (regular vs. non-participant; RR 1.20 95% CI 1.04-1.40). Highly educated under-screened mothers of the invited cohort showed a higher probability of receiving a Pap test after the vaccination campaign period (RR 1.27 95% CI 1.04-1.56) compared with those not invited, CONCLUSION: Active invitation

Full Text Available Background & objectives: Dental caries is an infectious, transmissible disease. Maternal transfer of mutans streptococci (MS has been a subject of research. The aim of this study was to evaluate the transmission of MS from mother to children through genetic analysis. Methods: Thirty mother-child pairs were included and divided into three groups according to the age of the children. Saliva samples were collected and MS colonies from each mother-child pair were isolated. After inoculation and incubation, MS colonies were submitted to amplification technique by polymerase chain reaction (PCR for identification and arbitrarily primed PCRs (AP-PCRs to determine various MS genotypes. Results: From birth to six months of age, 30 per cent of children exhibited MS colonization, and by the age of 30 months, 100 per cent harboured the bacteria (P < 0.001. Factors associated with MS colonization were eruption of teeth (P < 0.001, feeding habits with mean colony count being significantly lower in breast-fed as compared to bottle-fed children (P < 0.001 and a significant association between mean MS count of child and mother′s practice of sharing spoon with child (P < 0.001. The AP-PCR fingerprinting profile analysis showed 17 MS groups (clusters containing identical or highly related isolates in mother-child pairs with a high level of similarity (77.27 %. Interpretation & conclusions: The presence of matching MS genotypes suggested vertical transmission from mothers to children. Feeding habits, gum cleaning and number of erupted teeth in children had significant effect on MS colonization. There is a need to develop strategies to present MS colonization in children.

In this study, we examined whether mother-daughter sexuality communication in midadolescence contributes to young women's self-efficacy to consult with family members about sexual health problems, and to talk with physicians about the human papillomavirus (HPV). Young European American, Latina, and Asian Pacific Islander college women reported on how confident they felt talking to their family members and doctors about HPV and sexual health issues. We gathered retrospective data regarding the nature of mother-daughter communication, including sexuality communication, in midadolescence. Other variables included physician trust, knowledge about HPV, and reports of current sexual activity. More openness in past general communication with their mothers, more perceived comfort in past sexuality communication, and a greater number of reproductive health topics discussed was linked to greater confidence in communicating with family members about sexual health problems. In addition, higher levels of sexual activity, more knowledge about HPV, and the number of reproductive health topics discussed with mothers in midadolescence, were associated with increased confidence talking to doctors about HPV and sexual health. Positive communication experiences with mothers in the early years may reduce the shame, embarrassment, and anxiety associated with talking to physicians about sensitive sexuality issues.

Sex allocation and secondary sex ratio in Cuban boa ( Chilabothrus angulifer): mother's body size affects the ratio between sons and daughters

Frynta, Daniel; Vejvodová, Tereza; Šimková, Olga

Secondary sex ratios of animals with genetically determined sex may considerably deviate from equality. These deviations may be attributed to several proximate and ultimate factors. Sex ratio theory explains some of them as strategic decisions of mothers improving their fitness by selective investment in sons or daughters, e.g. local resource competition hypothesis (LRC) suggests that philopatric females tend to produce litters with male-biased sex ratios to avoid future competition with their daughters. Until now, only little attention has been paid to examine predictions of sex ratio theory in snakes possessing genetic sex determination and exhibiting large variance in allocation of maternal investment. Cuban boa is an endemic viviparous snake producing large-bodied newborns (˜200 g). Extremely high maternal investment in each offspring increases importance of sex allocation. In a captive colony, we collected breeding records of 42 mothers, 62 litters and 306 newborns and examined secondary sex ratios (SR) and sexual size dimorphism (SSD) of newborns. None of the examined morphometric traits of neonates appeared sexually dimorphic. The sex ratio was slightly male biased (174 males versus 132 females) and litter sex ratio significantly decreased with female snout-vent length. We interpret this relationship as an additional support for LRC as competition between mothers and daughters increases with similarity of body sizes between competing snakes.

The daughter centriole controls ciliogenesis by regulating Neurl-4 localization at the centrosome

Loukil, Abdelhalim; Tormanen, Kati

2017-01-01

The two centrioles of the centrosome differ in age and function. Although the mother centriole mediates most centrosome-dependent processes, the role of the daughter remains poorly understood. A recent study has implicated the daughter centriole in centriole amplification in multiciliated cells, but its contribution to primary ciliogenesis is unclear. We found that manipulations that prevent daughter centriole formation or induce its separation from the mother abolish ciliogenesis. This defect was caused by stabilization of the negative ciliogenesis regulator CP110 and was corrected by CP110 depletion. CP110 dysregulation may be caused by effects on Neurl-4, a daughter centriole–associated ubiquitin ligase cofactor, which was required for ciliogenesis. Centrosome-targeted Neurl-4 was sufficient to restore ciliogenesis in cells with manipulated daughter centrioles. Interestingly, early during ciliogenesis, Neurl-4 transiently associated with the mother centriole in a process that required mother–daughter centriole proximity. Our data support a model in which the daughter centriole promotes ciliogenesis through Neurl-4–dependent regulation of CP110 levels at the mother centriole. PMID:28385950

While risk may relate to depressed mothers' difficulties regulating emotions in the context of interacting with offspring, physiological indicators of emotion regulation have rarely been examined during mother–child interactions—and never among mother–adolescent dyads in which both mother and adolescent have histories of major depressive disorder (MDD). Methods We examined changes in high-frequency heart rate variability (HF-HRV), an indicator of parasympathetic (vagal) function that has been related to depression, stress, social engagement, and emotion regulation, in 46 mother–daughter dyads (23 in which both mother and daughter had an MDD history and 23 never-depressed controls). Hierarchical linear models evaluated changes in HF-HRV while mother–daughter dyads engaged in discussions about shared pleasant events and relationship conflicts. Results While control dyads displayed positive slopes (increases) in HF-HRV during both discussions, MDD dyads displayed minimal change in HF-HRV across discussions. Among controls, HF-HRV slopes were positively correlated between mothers and daughters during the pleasant events' discussion. In contrast, HF-HRV slopes were negatively correlated between MDD mothers and daughters during both discussions. Conclusions Vagal responses observed in control mother–daughter dyads suggest a pattern of physiological synchrony and reciprocal positive social engagement, which may play a role in adolescent development of secure social attachments and healthy emotion regulation. In contrast, MDD mothers and daughters displayed diminished and discordant patterns of vagal responsiveness. More research is needed to understand the development and consequences of these patterns of parasympathetic responses among depressed mother–daughter dyads. PMID:28060443

We report on a family in which a mother and her 3 daughters have delayed psychomotor development and/or psychosis, hydrocephalus with white matter alterations, arachnoid cysts, skeletal anomalies consisting of brachydactyly, and Sprengel anomaly. Biochemical and cytogenetic analyses were normal on all 4 patients. The pattern of inheritance, clinical manifestations, and variability of expression suggest that this is a new hydrocephalus syndrome possibly transmitted as an X-linked dominant trait. 24 refs., 6 figs., 1 tab.

To determine the prevalence of Streptococcus mutans (MS) in mother-child pairs and to evaluate the correlation in the levels of salivary MS of working and nonworking mothers with that of their children and their associations with other related factors. A cross-sectional study was carried out among 100 mother-child pairs residing in New Multan Nagar Colony, New Delhi, India. A total of 50 children with their mothers were included in the working group and another 50 were included in the nonworking group. A questionnaire regarding the feeding habits, oral hygiene habits, daily intake of sugars of the children along with their weaning time was carried out. All mothers and children were clinically examined for recording decayed, extracted, and filled teeth (deft)/decayed, missing, and filled teeth (DMFT), and whole unstimulated saliva was collected and cultured for MS in the laboratory. The data were collected and subjected to statistical analysis using chi-square, Spearman's correlation, and logistic regression analysis. The prevalence of salivary MS in the children was 69%. A statistically significant correlation was found between the oral levels of MS in nonworking and working mother-child pairs. Regression analysis showed that those children who feed by bottle for more than 12 months, have daily sweet intake, have sugars in feeding bottle and have higher defts were more likely to have mutans score of 1 or 2. The mother, working or nonworking, being the primary care provider is the major source of transmission of MS to their child irrespective of the amount of time spent with them.

Full Text Available The problem of genetic versus environmental influences in psychiatric disorders is widely discussed in biomedical literature, but remains still controversial. Familiarity has been observed in some disesase, such as obsessive-compulsive disorder and panic attack disorder. In this study we analyse three generations of women, for a total of 4 women (a mother, her two daughters, and a granddaughter followed by our Psychiatric Department for depressive and anxiety disorders. The aim of the study was to assess wheather there are similarities among the clinical status of the four women, and verify the relationship among those disorders. The Minnesota Multiphasic Personality Inventory (MMPI was administered to all the patients and the scores obtained were compared. We found out that the many aspects and psychological traits were present in all the four women. These similarities suggest the presence of a dynamic trans-generational transmission.

First, to explore the kind of information that Mexican mothers give their daughters about menstruation before their menarche, and to study the impact of this communication on how prepared the daughters felt when they experienced their menarche. Second, to investigate the influence of the menarcheal experience on attitudes toward menstruation. Cross-sectional survey. Sample of adolescents attending 3 different public schools. 405 Mexican postmenarcheal adolescents, aged 12-15 years. Participants answered a questionnaire that had 3 parts: (a) General data, (b) topics related to menses that participants had discussed with their mothers prior to menarche, and (c) menarcheal experience. They also answered a questionnaire about menstrual attitudes. Although most of the participants knew what they should do when they experienced their menarche, only 39% stated they had felt prepared to start menstruating. Regarding menstrual attitudes, adolescents scored highest on Negative Feelings and Secrecy rather than on Positive Feelings. Participants who had previously discussed the emotional aspects of menses with their mothers were more likely to claim they had felt prepared to start menstruating when they got their first period (OR = 3.45). The fact that adolescents felt prepared to start menstruating predicted positive attitudes toward menstruation (β = .19) Discussing the emotional aspects of menses prior to menarche is crucial to being prepared for menarche, and to holding positive attitudes toward menstruation. Information on biological knowledge and practical aspects of menses needs to be supplemented with emotional issues. Copyright © 2012 North American Society for Pediatric and Adolescent Gynecology.

This study examined whether maternal adiposity, acculturation, and perceived-ideal body size discrepancy for daughters were associated with daughters' engagement in unhealthy weight control behaviors. A total of 97 Hispanic mother-daughter dyads completed surveys, rated a figure scale, and had their height, weight, and adiposity assessed. Mothers (M age =39.00, SD=6.20 years) selected larger ideal body sizes for their daughters (M age =11.12, SD=1.53 years) than their daughters selected for themselves. Mothers had a smaller difference between their perception of their daughters' body size and ideal body size compared to the difference between their daughters' selection of their perceived and ideal body size. More acculturated mothers and those mothers with larger waist-to-hip ratios were more likely to have daughters who engaged in unhealthy weight control behaviors. These findings highlight the relevant role that maternal acculturation and adiposity may have in influencing daughters' unhealthy weight control behaviors. Published by Elsevier Ltd.

Developmental theories of borderline personality disorder (BPD) posit that transactions between child characteristics and adverse environments, especially those in the context of the parent-child relationship, shape and maintain symptoms of the disorder over time. However, very little empirical work has investigated the role of parenting and parent-child transactions that may predict BPD severity over time. We examined maternal and dyadic affective behaviors during a mother-adolescent conflict discussion task as predictors of the course of BPD severity scores across 3 years in a diverse, at-risk sample of girls (N = 74) oversampled for affective instability and their biological mothers. Adolescent girls completed a structured conflict discussion task with their mothers at age 16. Girls' self-reported BPD severity scores were assessed annually from ages 15 to 17. Mother-adolescent interactions were coded using a global rating system of maternal and dyadic affective behaviors. Results from multilevel linear mixed models indicated that positive maternal affective behavior (i.e., supportive/validating behavior, communication skills, autonomy-promoting behavior, and positive affect) and positive dyadic affective behaviors (i.e., satisfaction and positive escalation) were associated with decreases in girls' BPD severity scores over time. Dyadic negative escalation was associated with higher overall levels of BPD severity scores, but negative maternal affective behavior (i.e., negative affect, dominance, conflict, and denial) was not. These findings suggest that the mother-daughter context is an important protective factor in shaping the course of BPD severity scores during adolescence and may be valuable in assessment, intervention, and prevention efforts.

Plk1 relieves centriole block to reduplication by promoting daughter centriole maturation

Centrosome overduplication promotes mitotic abnormalities, invasion and tumorigenesis. Cells regulate the number of centrosomes by limiting centriole duplication to once per cell cycle. The orthogonal orientation between a mother and a daughter centriole, established at the time of centriole duplication, is thought to block further duplication of the mother centriole. Loss of orthogonal orientation (disengagement) between two centrioles during anaphase is considered a licensing event for the next round of centriole duplication. Disengagement requires the activity of Polo-like kinase 1 (Plk1), but how Plk1 drives this process is not clear. Here we employ correlative live/electron microscopy and demonstrate that Plk1 induces maturation and distancing of the daughter centriole, allowing reduplication of the mother centriole even if the original daughter centriole is still orthogonal to it. We find that mother centrioles can undergo reduplication when original daughter centrioles are only ∼80 nm apart, which is the distance centrioles normally reach during prophase. PMID:26293378

Daughter-Initiated Cancer Screening Appeals to Mothers.

Youth-initiated health interventions may provide a much needed avenue for intergenerational dissemination of health information among families who bear the greatest burden from unequal distribution of morbidity and mortality. The findings presented in this paper are from a pilot study of the feasibility and impact of female youth-initiated messages (mostly daughters) encouraging adult female relatives (mostly mothers) to obtain cancer screening within low-income African American families living in a Southern US state. Results are compared between an intervention and control group. Intervention group youth (n = 22) were exposed to a 60-min interactive workshop where they were assisted to prepare a factual and emotional appeal to their adult relative to obtain specific screening. The face-to-face workshops were guided by the Elaboration Likelihood Model (ELM) and the Theory of Planned Behavior (TPB). Control group girls (n = 18) were only provided with a pamphlet with information about cancer screening and specific steps about how to encourage their relative to obtain screening. Intervention youth (86 %) and adults (82 %) reported that the message was shared while 71 % in the control group reported sharing or receiving the message. Importantly, more women in the intervention group reported that they obtained a screen (e.g., mammogram, Pap smear) directly based on the youth's appeal. These findings can have major implications for youth-initiated health promotion efforts, especially among hard-to-reach populations.

Asterless licenses daughter centrioles to duplicate for the first time in Drosophila embryos.

Novak, Zsofia A; Conduit, Paul T; Wainman, Alan; Raff, Jordan W

Centrioles form centrosomes and cilia, and defects in any of these three organelles are associated with human disease [1]. Centrioles duplicate once per cell cycle, when a mother centriole assembles an adjacent daughter during S phase. Daughter centrioles cannot support the assembly of another daughter until they mature into mothers during the next cell cycle [2-5]. The molecular nature of this daughter-to-mother transition remains mysterious. Pioneering studies in C. elegans identified a set of core proteins essential for centriole duplication [6-12], and a similar set have now been identified in other species [10, 13-18]. The protein kinase ZYG-1/Sak/Plk4 recruits the inner centriole cartwheel components SAS-6 and SAS-5/Ana2/STIL, which then recruit SAS-4/CPAP, which in turn helps assemble the outer centriole microtubules [19, 20]. In flies and humans, the Asterless/Cep152 protein interacts with Sak/Plk4 and Sas-4/CPAP and is required for centriole duplication, although its precise role in the assembly pathway is unclear [21-24]. Here, we show that Asl is not incorporated into daughter centrioles as they assemble during S phase but is only incorporated once mother and daughter separate at the end of mitosis. The initial incorporation of Asterless (Asl) is irreversible, requires DSas-4, and, crucially, is essential for daughter centrioles to mature into mothers that can support centriole duplication. We therefore propose a "dual-licensing" model of centriole duplication, in which Asl incorporation provides a permanent primary license to allow new centrioles to duplicate for the first time, while centriole disengagement provides a reduplication license to allow mother centrioles to duplicate again.

Unreliable Bodies: A Follow-up Twenty Years Later by a Mother and Daughter about the Impact of Illness and Disability on their Lives.

Weingarten, Kaethe; Worthen, Miranda

2017-03-01

We are a mother and daughter, both health care professionals, who offer a follow-up to an article we published twenty years ago about the impact of each other's ongoing, serious medical problems on our relationship. In this article, we contribute a long-term perspective on the differences between having an illness that is well or poorly understood by medical professionals and the lay community. We also discuss health in the context of identity formation and life stage, as during this interval the daughter left home, graduated college, married, and had two children. Also in this period, the mother survived a third breast cancer and other life-threatening illnesses. We discuss the impact of these experiences on each other and in other important relationships in our lives. Current discourses on daughters of breast cancer survivors do not fit our experience and we speculate about why our story differs. We find that although we continue to contend with serious medical issues that impact our own, each other's, and our families' lives, nonetheless, our lives are rich, rewarding, and "appropriate" for our life stage. That is the news. © 2015 Family Process Institute.

Higher Stakes: Generational Differences in Mother and Daughters’ Feelings about Combining Motherhood with a Career

Directory of Open Access Journals (Sweden)

Jill Armstrong

2017-08-01

Full Text Available The purpose of this article is to illuminate differences in feelings and attitudes about managing motherhood and work between career women and their adult daughters. Intergenerational narrative interviews with 30 mother and daughter pairs are used to explore the relative influences of contemporary motherhood culture and the experience of being mothered by a woman who also worked full-time or close to full-time in a professional or managerial career. Almost all the daughters felt well-mothered and planned or had embarked upon a high-status career path. Despite this, a clear majority did not want to emulate their mothers and instead embraced a dominant idea that part-time work offers ‘the best of both worlds’. The daughters are strongly influenced by the contemporary culture of motherhood with its growing emphasis on ‘balance’ (measured by time, individualisation and parental determinism. It appears that the stakes have been raised to make it feel too risky to one’s child’s well-being and progress to emulate the more pragmatic attitude to combining work and motherhood demonstrated by many of their own mothers. Much research demonstrates that part-time work presents strong barriers both to career satisfaction and progress. This reinforces the need for organisations to offer more genuinely flexible ways of working in senior roles and for policy initiatives to facilitate the greater involvement of fathers in caring for their children. For individuals, I advocate challenging the idea of measuring good mothering by ‘balanced’ hours spent at work and at home.

HPV vaccination rates among adolescents in the United States lag behind some other developed countries, many of which routinely offer the vaccine in schools. We sought to assess mothers' willingness to have their adolescent daughters receive HPV vaccine at school. A national sample of mothers of adolescent females ages 11-14 completed our internet survey (response rate=66%). The final sample (n=496) excluded mothers who did not intend to have their daughters receive HPV vaccine in the next year. Overall, 67% of mothers who intended to vaccinate their daughters or had vaccinated their daughters reported being willing to have their daughters receive HPV vaccine at school. Mothers were more willing to allow their daughters to receive HPV vaccine in schools if they had not yet initiated the vaccine series for their daughters or resided in the Midwest or West (all pconcerns about voluntary school-based provision of HPV vaccine that mothers most frequently cited were that their daughters' doctors should keep track of her shots (64%) and that they wished to be present when their daughters were vaccinated (40%). Our study suggests that most mothers who support adolescent vaccination for HPV find school-based HPV vaccination an acceptable option. Ensuring communication of immunization records with doctors and allowing parents to be present during immunization may increase parental support. Copyright © 2011 Elsevier Ltd. All rights reserved.

Control of daughter centriole formation by the pericentriolar material: Control of centriole duplication

2008-01-01

Controlling the number of its centrioles is vital for the cell as supernumerary centrioles result in multipolar mitosis and genomic instability1,2. Normally, just one daughter centriole forms on each mature (mother) centriole3,4; however, a mother centriole can produce multiple daughters within a single cell cycle5,6. The mechanisms that prevent centriole ‘overduplication’ are poorly understood. Here we use laser microsurgery to test the hypothesis that attachment of the daughter centriole to...

Shared vision between fathers and daughters in family businesses: the determining factor that transforms daughters into successors

2015-01-01

Family businesses are critical to the United States economy, employing 63% of the workforce and generating 57% of GDP (University of Vermont, 2014). Family business continuity, however, remains elusive as approximately 70% of family businesses do not survive the second generation (Poza, 2013). In order to augment our understanding of how next generation leaders are chosen in family businesses, we examine daughter succession. Using a sample of pairs of family business fathers and daughters and drawing on an earlier study of the dearth of successor daughters in family businesses (Overbeke et al., 2013), we reveal that shared vision between fathers and daughters is central to daughter succession. Self-efficacy and gender norms influence shared vision and when fathers and daughters share a vision for the future of the company, daughters are likely to be transformed into successors.

Competitive mothering and delegated care: Class relationships in nanny and au pair employment

Directory of Open Access Journals (Sweden)

Rosie Cox

2011-07-01

Full Text Available This paper uses the idea of 'competitive care' to explore how the mothering projects of nanny and au pair employers and the carers they employ can become inter-twined and yet may also be in conflict or competition. The paper draws on work by Cameron Lynne Macdonald (2010 and Joan Tronto (2006 to make two arguments about the inter-twining of current practices of competitive mothering and the employment of nannies and au pairs. First, practices of competitive mothering can underpin the demand for paid, privatized care in the home (such as nannies and au pairs and involve middle class / advantaged women using their position to raise their children in ways which are specifically designed to ensure and enhance their children's future social status and income. This can be at the cost of the mothering projects (and children of the women they employ. Second, one factor which underlies the prevalence of competitive mothering within certain middle class families is the conflict that working mothers feel about their roles and their strong desire to address these conflicts by showing that their children do not suffer because of their employment. The emphasis on care for children as mothering, rather than parenting – or better still 'care' – underpins this sense of conflict. The idea that it is mothers, rather than parents or society at large, who are delegating care is an important element in the organisation of care, and the relationships with carers that ensue.

Cdk1 Phosphorylates Drosophila Sas-4 to Recruit Polo to Daughter Centrioles and Convert Them to Centrosomes.

Science.gov (United States)

Novak, Zsofia A; Wainman, Alan; Gartenmann, Lisa; Raff, Jordan W

2016-06-20

Centrosomes and cilia are organized by a centriole pair comprising an older mother and a younger daughter. Centriole numbers are tightly regulated, and daughter centrioles (which assemble in S phase) cannot themselves duplicate or organize centrosomes until they have passed through mitosis. It is unclear how this mitotic "centriole conversion" is regulated, but it requires Plk1/Polo kinase. Here we show that in flies, Cdk1 phosphorylates the conserved centriole protein Sas-4 during mitosis. This creates a Polo-docking site that helps recruit Polo to daughter centrioles and is required for the subsequent recruitment of Asterless (Asl), a protein essential for centriole duplication and mitotic centrosome assembly. Point mutations in Sas-4 that prevent Cdk1 phosphorylation or Polo docking do not block centriole disengagement during mitosis, but block efficient centriole conversion and lead to embryonic lethality. These observations can explain why daughter centrioles have to pass through mitosis before they can duplicate and organize a centrosome. Copyright © 2016 The Author(s). Published by Elsevier Inc.

2009-10-01

In budding yeast, asymmetric cell division yields a larger mother and a smaller daughter cell, which transcribe different genes due to the daughter-specific transcription factors Ace2 and Ash1. Cell size control at the Start checkpoint has long been considered to be a main regulator of the length of the G1 phase of the cell cycle, resulting in longer G1 in the smaller daughter cells. Our recent data confirmed this concept using quantitative time-lapse microscopy. However, it has been proposed that daughter-specific, Ace2-dependent repression of expression of the G1 cyclin CLN3 had a dominant role in delaying daughters in G1. We wanted to reconcile these two divergent perspectives on the origin of long daughter G1 times. We quantified size control using single-cell time-lapse imaging of fluorescently labeled budding yeast, in the presence or absence of the daughter-specific transcriptional regulators Ace2 and Ash1. Ace2 and Ash1 are not required for efficient size control, but they shift the domain of efficient size control to larger cell size, thus increasing cell size requirement for Start in daughters. Microarray and chromatin immunoprecipitation experiments show that Ace2 and Ash1 are direct transcriptional regulators of the G1 cyclin gene CLN3. Quantification of cell size control in cells expressing titrated levels of Cln3 from ectopic promoters, and from cells with mutated Ace2 and Ash1 sites in the CLN3 promoter, showed that regulation of CLN3 expression by Ace2 and Ash1 can account for the differential regulation of Start in response to cell size in mothers and daughters. We show how daughter-specific transcriptional programs can interact with intrinsic cell size control to differentially regulate Start in mother and daughter cells. This work demonstrates mechanistically how asymmetric localization of cell fate determinants results in cell-type-specific regulation of the cell cycle.

For young women with breast cancer mothers might either be a source of support or of increased stress, depending on the premorbid relationship and on the psychological effect of the daughter's diagnosis on her mother. To examine the effects of a breast cancer diagnosis on young women's relationships with their mothers and the possible support needs of these mothers from the daughters' perspective. We developed and pre-tested a self-administered questionnaire on 10 survivors of breast cancer diagnosed ≤ age 40. Then, consecutive recurrence-free young women diagnosed with breast cancer were asked to complete the modified questionnaire. Of 110 daughters approached from July/11 to May/12, 90 (82%) participated. In 11 cases (13%), the daughters had turned to their mothers before approaching anyone else. Of the 83 daughters who disclosed their diagnosis to their mothers, 76 (92%) stated their mothers had been emotionally and/or practically supportive, and 43 (54%) reported that the breast cancer diagnosis had a favorable impact on their relationship with their mothers. Of the 35 employed mothers, 26 had taken time off from work to support their daughters. Nineteen mothers, eight of whom had been living in a different country, had slept over or moved in with daughters during their treatment. Twenty-two daughters believed their mothers felt responsible to some extent for their developing breast cancer. Fifty-nine daughters indicated that health care professionals could help mothers by providing information pamphlets, education sessions, and linking to support groups. Mothers are an important source of support for young daughters with breast cancer, with the mother-daughter relationship frequently becoming closer after the diagnosis. However, the practical and emotional burden on mothers appears to be high. Future studies should address the effects of a breast cancer diagnosis in young daughters from the mothers' perspective, and the benefit of formal supports for these

To determine the preference of mothers in Hong Kong and their willingness to pay (WTP) for human papillomavirus (HPV) vaccination for their daughters. A discrete choice experiment survey with a two-alternative study design was developed. Data were collected from pediatric specialist outpatient clinics from 482 mothers with daughters aged between 8 and 17 years. Preferences of the four attributes of HPV vaccines (protection against cervical cancer, protection duration, side effects, and out-of-pocket costs) were evaluated. The marginal and overall WTP were estimated using multinomial logistic regression. A subgroup analysis was conducted to explore the impact of socioeconomic factors on mothers' WTP. Side effects, protection against cervical cancer, protection duration, and out-of-pocket cost determined the decision to receive or not receive the vaccine. All attributes had a statistically significant effect on the preference of and the WTP for the vaccine. Maximum WTP for ideal vaccines (i.e., 100% protection, lifetime protection duration, and 0% side effects) was HK$8976 (US $1129). The estimated WTP for vaccines currently available was HK$1620 (US $208), lower than the current market price. Among those who had a monthly household income of more than HK$100,000 (US $12,821), the WTP for vaccines currently offered was higher than the market price. This study provides new data on how features of the HPV vaccine are viewed and valued by mothers by determining their perception of ideal or improved and current vaccine technologies. These findings could contribute to future policies on the improvement of HPV vaccine and be useful for the immunization service in Hong Kong.

The purpose of this study was to investigate gender-specific variations in the associations between communication with father and mother, cigarette smoking, alcohol drinking and marijuana use in male and female adolescents. Cross-sectional data were collected from a national sample of 1308 tenth graders who participated in the 2005/06 U.S. HBSC. Outcome variables were self-reported substances used in the past 30 days. Logistic regression analyses controlling for race/ethnicity, family structure and socioeconomic status showed that the association of mother and father communication with adolescent substance use varied by substance and gender. Among sons, father communication was protective against marijuana use and mother communication was protective against smoking. Neither father nor mother communication was protective against substance use by daughters. Research is needed to understand gender-specific differences in correlates of adolescent substance use and the implications for prevention and intervention. Copyright (c) 2009 Elsevier Ltd.

Objective Emerging evidence suggests that exposures during fetal life affect adult metabolism. We assessed the relation between recalled maternal pre-pregnancy body mass, gestational weight gain (GWG), and adiposity in the daughter. Design Retrospective cohort study among mother-nurse daughter dyads in the Nurses’ Health Study II and the Nurses’ Mothers’ Cohort. Mothers of participants completed questionnaires regarding their nurse-daughter in 2001. Participants 26,506 mother-nurse daughter dyads born between 1946 and 1964. Main outcome measures Body mass index of the nurse-daughter at age 18 and in 2001. Results At age 18, 561 (2.1%) daughters were obese (BMI greater than 30), and in 2001, 5,442 (22.0%) were obese. Adjusting for covariates, women whose mothers had a recalled pre-pregnancy BMI of 29 had a 6.1-fold increased risk of obesity at age 18 and a 3.4-fold risk of obesity in 2001, compared with women whose mothers had a pre-pregnancy BMI of 21. We found a U-shaped association between recalled GWG and offspring obesity. Compared with a maternal weight gain of 15–19 lb, GWG obesity risk at age 18 (odds ratio[OR] 1.54, 95% confidence interval[CI] 1.02–2.34) and in 2001 (OR 1.27, 95%CI 1.05–1.53). High weight gain (40+ lbs) was also associated with obesity risk at age 18 (OR 1.81, 95%CI 1.22–2.69) and in 2001 (OR 1.74, 95%CI 1.48–2.04). These associations were stronger among mothers who were overweight prior to pregnancy (p for interaction = 0.03), and they persisted with adjustment for birth weight. Conclusion A high recalled pre-pregnancy BMI and extremes of recalled GWG are associated with an increased risk of adolescent and adult obesity in offspring, particularly when the mother is overweight. Pre-pregnancy weight and GWG may be modifiable fetal origins of overweight and obesity in women. PMID:19528964

Transmitting Ainu traditional food knowledge from mothers to their daughters.

2017-11-01

Since 2004, research has been conducted in the Ainu Indigenous community of the Saru River Region of Biratori in Northern Japan examining traditional food use knowledge. The purpose was to improve the socio-cultural environment for the Ainu People by implementing interventions meant to reintroduce traditional Ainu food use, so that they can live with dignity and in harmony with non-Ainu people in the heterogeneous community where Japanese cultural values dominate. Ten years after the start of this research, a series of interviews was conducted with Ainu mothers and daughters active in the community to evaluate the result of the interventions because, in accordance with culturally established Ainu gender roles, the Ainu women prepare the Ainu dishes. The interviews indicated that the community of both Ainu and non-Ainu people shared traditional Ainu food as a communal food at community events organized by the Ainu members of the community. The people in the community now identify traditional Ainu dishes with Ainu names, indicating the establishment of culinary and linguistic boundaries between Ainu traditional food and mainstream Japanese food. This also signals that the Ainu People have begun to establish a basis for reconstructing their unique ethnic identity, once suppressed by the government's former assimilation policy. © 2018 John Wiley & Sons Ltd.

Prevalence of occult hepatitis B virus (HBV) infection (OBI) was investigated in a paired mother-teenager population and HBV S gene variation including overt and occult HBV, was determined. A follow-up study based on an initial survey of 135 mother-teenager pairs was carried out through collection of questionnaires and blood samples HBsAg were detected by ELISA method, viral load by PCR amplification and HBV S gene by phylogenetic analysis. 102 pairs of subjects were followed-up. Blood samples from 94 mothers and 101 children were collected. OBI prevalence in mothers was 10.0% (6/60), significantly higher than 2.0% (2/101) in teenagers. Medians of viral load were 399.9 IU/ml and 247.6 IU/ml in overt and occult HBV strains, but without significant difference. 1 occult HBV strain belonged to genotype B with serotype adw while the other 7 were genotype C with serotype adr. 15 of the overt HBV strains belonged to genotype B with serotype adw and the other 8 were genotype C with serotype adr. Proportions of genotype-C strains were significantly higher in occult HBV strains than in overt HBV strains. OBI was seen in teenage-mother population.

Maternal antibodies may play a role in protecting newborns against malaria disease. Plasmodium falciparum parasite surface antigens are diverse, and protection from infection requires allele-specific immunity. Although malaria-specific antibodies have been shown to cross the placenta, the extent to which antibodies that respond to the full repertoire of diverse antigens are transferred from the mother to the infant has not been explored. Understanding the breadth of maternal antibody responses and to what extent these antibodies are transferred to the child can inform vaccine design and evaluation. We probed plasma from cord blood and serum from mothers at delivery using a customized protein microarray that included variants of malaria vaccine target antigens to assess the intensity and breadth of seroreactivity to three malaria vaccine candidate antigens in mother-newborn pairs in Malawi. Among the 33 paired specimens that were assessed, mothers and newborns had similar intensity and repertoire of seroreactivity. Maternal antibody levels against vaccine candidate antigens were the strongest predictors of infant antibody levels. Placental malaria did not significantly impair transplacental antibody transfer. However, mothers with placental malaria had significantly higher antibody levels against these blood-stage antigens than mothers without placental malaria. The repertoire and levels of infant antibodies against a wide range of malaria vaccine candidate antigen variants closely mirror maternal levels in breadth and magnitude regardless of evidence of placental malaria. Vaccinating mothers with an effective malaria vaccine during pregnancy may induce high and potentially protective antibody repertoires in newborns.

Derlan, Chelsea L; Umaña-Taylor, Adriana J; Toomey, Russell B; Updegraff, Kimberly A; Jahromi, Laudan B

2015-01-01

The current study examined whether a match or mismatch between teen mothers' cultural orientation and the cultural context of the family (i.e., familial ethnic socialization) predicted mother-daughter everyday and coparenting conflict, and in turn, teen mothers' adjustment. Participants were 204 Mexican-origin teen mothers (M age = 16.81 years; SD = 1.00). Consistent with a person-environment fit perspective, findings indicated that a mismatch between teen mothers' cultural orientation (i.e., high mainstream cultural involvement) and the cultural context of the family (i.e., higher levels of familial ethnic socialization) predicted greater mother-daughter everyday conflict and coparenting conflict 1 year later. However, when there was a match (i.e., high levels of familial ethnic socialization for teen mothers with high Mexican orientation), familial ethnic socialization was not associated with mother-daughter conflict. In addition, mother-daughter conflict was positively associated with depressive symptoms and engagement in risky behaviors 1 year later among all teen mothers.

Full Text Available The relationship between mother and child in the context of oral health has traditionally been exposed by the scientific literature in microbiology, which lacks a broad and necessary discussion of health and illness seen as processes, both biological and social. Objective: Investigate the family social determinants associated with the caries history of children and the need for dental treatment (NDT among their mothers was the objective of this study. Material and methods: This research employed a cross-sectional study of mother-child pairs living in southern Brazil. Data collection occurred in public institutions of early childhood education. The instruments included a structured questionnaire administered to mothers and clinical oral examinations of the mothers and children. The social variables considered were marital status, maternal education, number of children, income, employment status, and frequency of visits to a dental professional. The measured outcomes were the maternal NDT and child caries history. Data were analyzed by the chi-square test (χ2 and by discriminant analysis. Results: The final sample consisted of 272 mother-child pairs and it was found that the greatest need for treatment was among mothers with low educational level and low family income who rarely or never visited a dentist. Tooth decay was less frequent in only child, and most frequent in children of mothers with low educational attainment, and in children in lower income households who rarely or never visited the dentist. The social determinants of caries in children and of the maternal NDT were similar. It follows that the maternal NDT and caries history among children were strongly associated with maternal education (p<0.0001, household income (p<0.0001, and frequency of visits to a dental professional (0.0018. Caries history among children was also associated with number of children in the household (p<0.0001. Conclusions: The results suggest that the caries

Fetal exposure to parental smoking may have long-term impact on the development of disease in adulthood. We examined the association of parental smoking during pregnancy with risk of gestational diabetes mellitus (GDM) in the daughter. We included 15,665 singleton pregnancies from 10,152 women in the Nurses' Health Study II cohort whose mothers participated in the Nurses' Mothers' Cohort Study. Data on maternal and paternal smoking during pregnancy and associated covariates were recalled by the mothers. GDM diagnosis was self-reported by the daughters and was validated by medical record review in a previous study. We used log-binomial models with generalized estimating equations to estimate relative risks (RRs) and 95% confidence intervals (CIs). We observed a positive association between maternal heavy smoking during pregnancy and risk of GDM in the daughter. The multivariable-adjusted RRs (95% CIs) of GDM among women whose mothers did not smoke during pregnancy, continued smoking 1-14, 15-24, and ≥ 25 cigarettes/day were 1.00 (reference), 1.05 (0.81-1.35), 1.27 (0.95-1.70) and 1.98 (1.18-3.30), respectively (P for trend = 0.01). Further adjustment for the women's perinatal variables, adult-life characteristics and body mass index during various periods of life modestly attenuated the association. No association was observed between paternal smoking during the pregnancy period and risk of GDM in the daughter. Maternal heavy smoking (≥ 25 cigarettes/day) during pregnancy was associated with higher risk of gestational diabetes in the daughter. Further studies are warranted to confirm our findings and to elucidate the underlying mechanisms. Published by Oxford University Press on behalf of International Epidemiological Association 2016.

Blood and environmental samples, including a quarterly 6-day duplicate diet, for nine mother/child pairs from Eastern Europe have been monitored for 12 to >24 months with high precision stable lead isotope analysis to evaluate the changes that occur when the subjects moved from one environment (Eastern Europe) to another with different stable lead isotopes (Australia). The children were between 6 and 11 years of age and the mothers were between 29 and 37 years of age. These data were compared with an Australian control mother/child pair, aged 31 and 6 years, respectively. A rationale for undertaking this study of mother/child pairs was to evaluate if there were differences in the patterns and clearance rates of lead from blood in children compared with their mothers. Blood lead concentrations ranged from 2.1 to 3.9 microg/dl in the children and between 1.8 and 4.5 microg/dl in the mothers, but the mean of differences between each mother and her child did not differ significantly from zero. Duplicate diets contained from 2.4 to 31.8 microg Pb/kg diet; the mean+/- standard deviation was 5.5 +/- 2.1 microg Pb/kg and total daily dietary intakes ranged from 1.6 to 21.3 microg/day. Mean daily dietary intakes relative to body weight showed that the intake for children was approximately double that for the mothers (0.218 vs. 0. 113 microg Pb/kg body weight/day). The correlations between blood lead concentration and mean daily dietary intake either relative to body weight or total dietary intake did not reach statistical significance (p>0.05). Estimation of the lead coming from skeletal (endogenous) sources relative to the contribution from environmental (exogenous) sources ranges from 8 to 70% for the mothers and 12 to 66% for the children. The difference between mothers and children is not statistically significant (p = 0.28). The children do not appear to achieve the Australian lead isotopic profile at a faster rate than their mothers. These data provide evidence that

Daughters of women with polycystic ovary syndrome (PCOS) are thought to be at increased risk for developing stigmata of the syndrome, but the ontogeny during puberty is uncertain. We phenotyped daughters (n = 76) of mothers with PCOS and daughters (n = 80) from control mothers for reproductive and metabolic parameters characteristic of PCOS. We performed a matched case/control study at Penn State Hershey Medical Center that included non-Hispanic, white girls 4 to 17 years old. We obtained birth history, biometric, ovarian ultrasounds, whole-body dual-energy X-ray absorptiometry scan for body composition, 2-hour glucose challenged salivary insulin levels, and two timed urinary collections (12 hours overnight and 3 hours in the morning) for gonadotropins and sex steroids. We measured integrated urinary levels of adrenal (dehydroepiandrosterone sulfate) and ovarian [testosterone (TT)] steroids. Other endpoints included integrated salivary insulin levels and urinary luteinizing hormone levels. There were no differences in detection rates or mean levels for gonadotropins and sex steroids in timed urinary collections between PCOS daughters and control daughters, nor were there differences in integrated salivary insulin levels. Results showed that 69% of Tanner 4/5 PCOS daughters vs 31% of control daughters had hirsutism defined as a Ferriman-Gallwey score >8 (P = 0.04). There were no differences in body composition as determined by dual-energy X-ray absorptiometry between groups in the three major body contents (i.e., bone, lean body mass, and fat) or in ovarian volume between groups. Matched for pubertal stage, PCOS daughters have similar levels of urinary androgens and gonadotropins as well as glucose-challenged salivary insulin levels. Copyright © 2017 by the Endocrine Society

The purpose of this study was to examine among college women acquired breast cancer prevention information-seeking, desired apps and texts, and information given to mothers. Using a cross-sectional study, a survey was administered to college women at a southwestern university. College women (n = 546) used the Internet (44 %) for active breast cancer prevention information-seeking and used the Internet (74 %), magazines (69 %), and television (59 %) for passive information receipt. Over half of the participants desired breast cancer prevention apps (54 %) and texts (51 %). Logistic regression analyses revealed predictors for interest to receive apps were ethnicity (Hispanic), lower self-efficacy, actively seeking online information, and older age and predictors for interest to receive texts were lower self-efficacy and higher university level. Eighteen percent of college women (n = 99) reported giving information to mothers and reported in an open-ended item the types of information given to mothers. Predictors for giving information to mothers were actively and passively seeking online information, breast self-exam practice, and higher university level. Screenings were the most frequent types of information given to mothers. Breast cancer prevention information using apps, texts, or Internet and daughter-initiated information for mothers should be considered in health promotion targeting college students or young women in communities. Future research is needed to examine the quality of apps, texts, and online information and cultural differences for breast cancer prevention sources.

Wang, Youfa; Li, Ji; Caballero, Benjamin

2009-01-01

Objectives To examine the association and predictors of dietary intake resemblance between urban low-income African American adolescents and their mothers. Methods Detailed dietary data collected from 121 child-parent pairs in Chicago in Fall 2003 were used. The association was assessed using correlation coefficients, kappa, and percentage of agreement, and logistic regression models. Results Overall, the association was weak as indicated by correlations and other measures. None of the mother-son correlations for nutrients and food groups were greater than 0.20. Mother-daughter pairs had stronger correlations (0.26 for energy and 0.30 for fat). The association was stronger in normal weight- than overweight or obese mothers. Logistic models showed that mother being a current smoker, giving child more pocket money, and allowing child to eat or purchase snacks without parental permission or presence predicted a higher probability of resemblance in undesirable eating patterns, such as high-energy, high-fat, and high-snack intakes (p<0.05). Conclusions Mother-child diet association was generally weak, and varied considerably across groups and intake variables in this homogenous population. Some maternal characteristics seem to affect the association. PMID:19103323

The aim of the current analysis is to evaluate any differences of breast or ovarian cancer age at diagnosis between mothers and daughters carrying the c.3481_3491del11 mutation in the BRCA1 gene. A study cohort of 38 women carrying the c.3481_3491del11 mutation and affected by first breast or ovarian cancer who reported a first breast or ovarian cancer in their mother carrying the c.3481_3491del11 mutation, was identified in 37 different families including members with breast and/or ovarian cancer at the Oncology Institute of Lorraine. Twelve mothers underwent genetic testing. Twenty-five pairs of the 38 mothers-daughters pairs with c.3481_3491del11 mutation were affected by breast cancer and 13 pairs by ovarian cancer. Clinical and genetic data were collected from medical files and family pedigrees. Analyses were conducted for each cancer type. We investigated an early breast cancer detection effect due to early screening programs and also an increased breast tumor aggression. Since major improvements in breast cancer clinical management and imaging techniques appeared after 1980, we compared the age at breast cancer diagnosis and the age at death in mothers and daughters before and after 1980, first, in the group of women including mothers and daughters taken together and then in mothers and daughters separately. The mean age at breast cancer diagnosis was 45.28 ± 10.27 years in mothers and 39.80 ± 7.79 years in daughters (p = 0.026). The difference of age at ovarian cancer diagnosis in mother-daughter pairs was 8.62 ± 12.76 years (p = 0.032). When considering the group of women including mothers and daughters taken together, no significant difference of age at breast cancer diagnosis was found between women affected before 1980 and those affected after 1980 (p = 0.577). However, the age at death increased in these women after 1980 (p = 0.026). Comparison of age at breast cancer diagnosis in mothers and daughters separately

Mothers in "incest families": a critique of blame and its destructive sequels.

Science.gov (United States)

Green, J

1996-09-01

This paper critically reviewed the blame-oriented explanations of mothers' roles in father-daughter incest, which was contrasted with feminist reassessments in a sociopolitical context. The concept of the dysfunctional family forms the matrix in which views of blaming the mother take life. The mother is characterized as the ¿cornerstone¿ of the family dynamics that create and maintain the incestuous behavior of the spouse. Several categories of maternal behavior were reported to set up conditions in the family for father-daughter incest, including the contention that the mother colludes in the abuse either by unconscious passivity or by active conscious involvement in arranging the act. In addition, the mother's alleged inadequacies in the areas of intimacy and sexuality are often viewed as central factors in the dynamics of father-daughter incest. Identified as additional victims in the complex matrix of family and community, mothers are revictimized by the clinical establishment that upholds the unconscious patriarchal ideology underlying violence against women. Clinicians need to validate and support mothers in their ¿disenfranchised grief¿ so they can help their daughters to heal, and to design and lobby for programs that will promote social changes that are necessary for a more egalitarian society.

Impact of framing on intentions to vaccinate daughters against HPV: a cross-cultural perspective.

Lechuga, Julia; Swain, Geoffrey R; Weinhardt, Lance S

2011-10-01

Effective promotion of the human papilloma virus (HPV) vaccine across ethnic/racial groups may help curtail disparities in cervical cancer rates. This study aims to investigate mothers' intentions to vaccinate daughters against HPV as a function of message framing (gain versus loss) across three cultural groups: Hispanic, non-Hispanic white, and non-Hispanic African-American. One hundred fifty mothers were recruited from city department of health clinics and asked to respond to information about the HPV vaccine for their daughters. In a repeated-measures experiment, two different frames (gain and loss) were used to present the information. The results indicated that both frames are equally effective in promoting vaccination intentions in non-Hispanic white mothers. Conversely, a loss frame message was more effective in non-Hispanic African-American and Hispanic mothers. Information sharing campaigns, aimed at promoting the HPV vaccine among ethnic minority groups should be modified to not focus exclusively on the benefits of vaccination.

The FDA approved the first human papillomavirus (HPV) vaccine in 2006. Research into parental decision-making and concerns about HPV vaccination highlights questions about parenting and parents' role in the crafting of their daughters' future sexuality. In contrast to much of this literature, we explore narratives from interviews with Cambodian mothers of HPV vaccine-age eligible daughters who experienced genocide and came to the USA as refugees. We conducted in-depth, in-person interviews with 25 Cambodian mothers of HPV vaccine-age eligible daughters. Interviews were conducted in Khmer and translated into English for analysis. We followed standard qualitative analysis techniques including iterative data review, multiple coders, and 'member checking.' Five members of the research team reviewed all transcripts and two members independently coded each transcript for concepts and themes. Interview narratives highlight the presence of the past alongside desires for protection from uncertain futures. We turn to Quesada and colleagues' concept structural vulnerability to outline the constraints posed by these women's positionalities as genocide survivors when faced with making decisions in an area with which they have little direct knowledge or background: cervical cancer prevention. Our study sheds light on the prioritization of various protective health practices, including but not exclusive to HPV vaccination, for Khmer mothers, as well as the rationalities informing decision-making regarding their daughters' health.

Guided by structural family systems theory, this study explored the relationship between parentification and adolescent daughters' sexual risk engagement and substance use. We also explored how adolescent reports of parental monitoring moderated the relationship between parentification and adolescent risk. Data were from a cross-sectional, cross-generational study of 176 mother-daughter dyads from low-income, inner-city, ethnic minority families. In this sample, which included a subset of mothers with HIV, parental physical symptoms were associated with slightly higher levels of parentification. Parentification was associated with adolescent daughters' intention to have sex (but not substance use) in a direction opposite to prediction. Higher parentification was associated with lower intention to have sex. Parental monitoring did not moderate relationships between parentification and adolescent risk. These findings highlight that despite the negative influence hypothesized in structural family systems theory, parentification was not associated with risk engagement of high-risk adolescent daughters in ethnic minority families with low income. © 2013 FPI, Inc.

Mother-daughter relationship was the focus of studies on the development of eating disorders (ED) for many years. This study aimed to examine the association between the father-daughter relationship and ED and depressive symptoms. Fifty-three women diagnosed with ED were compared to a psychiatric control group (n=26) and to healthy participants (n=60) regarding their perception of their fathers and the relationship with them. Assessments were done using the Parental Bonding Instrument, the Eating Disorders Questionnaire, the Body Shape Questionnaire, the Eating Attitude Test, and the Beck Depression Inventory as well as narrative-based methods. Fathers' negative attributes were significantly associated with ED and depressive symptom. Two profiles of father-daughter relationship were found, the "caring and benevolent" relationship and the "overprotective and avoidant" one. In the latter, patients displayed significantly higher levels of food-restraint, more concerns about eating and about their body shape and appearance, and higher levels of depression. Negative perception of the father's parenting style as well as the quality of the relationship with him are crucial for the understanding of the development and persistence of ED. Therapeutic programs for ED should focus not only on the relationship with the mother but must also address the relationship with the father. Copyright © 2014 Elsevier Masson SAS.

Like Mother(-in-Law) Like Daughter? Influence of the Older Generation's Fertility Behaviours on Women's Desired Family Size in Bihar, India.

Science.gov (United States)

Kumar, Abhishek; Bordone, Valeria; Muttarak, Raya

This paper investigates the associations between preferred family size of women in rural Bihar, India and the fertility behaviours of their mother and mother-in-law. Scheduled interviews of 440 pairs of married women aged 16-34 years and their mothers-in-law were conducted in 2011. Preferred family size is first measured by Coombs scale, allowing us to capture latent desired number of children and then categorized into three categories (low, medium and high). Women's preferred family size is estimated using ordered logistic regression. We find that the family size preferences are not associated with mother's fertility but with mother's education. Mother-in-law's desired number of grandchildren is positively associated with women's preferred family size. However, when the woman has higher education than her mother-in-law, her preferred family size gets smaller, suggesting that education provides women with greater autonomy in their decision-making on childbearing.

Skotko, Brian G; Levine, Susan P; Goldstein, Richard

2011-10-01

This study asks parents who have children with Down syndrome (DS) how they feel about their lives so that such information could be shared with expectant couples during prenatal counseling sessions. A valid and reliable survey instrument was mailed to 4,924 households on the mailing lists of six non-profit DS organizations. Of the 2,044 respondents, 99% reported that they love their son or daughter; 97% were proud of them; 79% felt their outlook on life was more positive because of them; 5% felt embarrassed by them; and 4% regretted having them. The parents report that 95% of their sons or daughters without DS have good relationships with their siblings with DS. The overwhelming majority of parents surveyed report that they are happy with their decision to have their child with DS and indicate that their sons and daughters are great sources of love and pride.

The association between maternal bonding style, offspring low self-esteem and offspring depression status was assessed by maternal depression status. Sixty mothers and 137 offspring were independently assessed over the course of a ten year follow-up study. Assessments included the Schedule for Affective Disorders and Schizophrenia (SADS-LA), Schedule for Affective Disorders and Schizophrenia for School-Aged Children (K-SADS), the Coopersmith Self-Esteem Inventory (CSEI) and the Parental Bonding Instrument (PBI). Among daughters of mothers with a history of depression, maternal affectionless-control was associated with daughter low self-esteem which was associated with daughter depression at ten year follow-up. Among daughters of mothers without a history of depression, maternal affectionless-control was not associated with daughter low self-esteem, which was not associated with daughter depression at ten year follow-up but which was associated with a history of childhood depression. None of these associations were found to be significant among sons. As self-esteem was not measured at ten year follow-up, among offspring the stability of self-esteem could not be assessed, nor could the association between adult self-esteem and adult depression. Clinical presentation of low self-esteem in girls should be assessed in the context of maternal depression status.

The First Teenage Pregnancy in the Family: Does It Affect Mothers’ Parenting, Attitudes, or Mother-Adolescent Communication?

East, Patricia L.

2013-01-01

To understand the consequences of adolescent pregnancy and childbearing for the family, 189 mothers from three types offamilies were studied: families in which all teenage daughters had never been pregnant, families in which only one teenager was currently pregnant, and families in which only one teenager had delivered a baby within the previous 6 months. in the latter two family types, the current pregnancy or childbearing was the first to occur in the family. Mothers were assessed twice, 13 months apart. Results indicated that, compared with the mothers of never-pregnant teens, the mothers of parenting teens monitored their children less. expected less of their older daughters, and were more accepting of teenage childbearing. Across-time analyses showed that, in families in which the teenager was initially pregnant, mothers monitored and communicated less with their other children and were more accepting of teenage sex after the older daughter gave birth. In families in which the teenager was initially parenting, mothers perceived more difficulty for their teenage daughters and reported being less strict with their other children across time.

Rh(D) fraction incompatibility causing hemolytic disease of the newborn. Report of two cases in a Chinese family.

Science.gov (United States)

Lee, S K; Tham, K T; Cheung, K P; Jenkins, W J

1982-07-01

Two cases of hemolytic disease of new born in a Chinese family are reported. The hemolysis was due to the production in the mother of antibodies against fractions A, C, and D of Rh(D) antigen. The fractions were absent in the mother's red blood cells which are Rh(DB) but present in her babies. Rh(DB) may be detected by the use of two types of anti-D sera, one with and the other without anti-DB activity. For transfusion purpose, all DB patients so tested, would be regarded as Rh(D) negative.

1986-04-01

Two types of single-parent households and their effects on children ages 3-11 years were compared. One type comprised 50 homosexual mothers and their 56 children, and the other was a group of 40 heterosexual mothers and their 48 children. There were 30 daughters and 26 sons of homosexual mothers and 28 daughters and 20 sons of heterosexual mothers. The sexual identity and social relationships of the children were assessed in relation to the sexual orientation of the mothers. The samples consisted of families from rural and urban areas in 10 American states. All have lived without adult males (18 years or older) in the household for a minimum of 2 years (average 4). Families with heterosexual mothers were matched to families with homosexual mothers on age and race of mother; length of mother and child separation from father; educational level and income of mother; and number, age, and sex of children. Data are reported from childrens' tests designed to provide information on general intelligence, core-morphologic sexual identity, gender-role preferences, family and peer group relationships, and adjustment to the single-parent family. No significant differences were found between the two types of households for boys and few significant differences for girls. Concerns that being raised by a homosexual mother might produce sexual identity conflict and peer group stigmatization were not supported by the research findings. Data also revealed more similarities than differences in parenting experiences, marital history, and present living situations of the two groups of mothers. The postulated compromised parental fitness of lesbian mothers, commonly asserted in child custody cases, is not supported by these data.

African American Mother–Daughter Communication About Sex and Daughters’ Sexual Behavior: Does College Racial Composition Make a Difference?

Science.gov (United States)

Bynum, Mia Smith

2014-01-01

This study examined the influence of African American mothers’ communication about sexual topics on the sexual attitudes and behavior of their college-enrolled daughters. Daughters were enrolled at a historically Black college/university (HBCU) or a predominantly White institution (PWI) to assess whether and how college racial context might affect daughters’ sexual attitudes and behavior. Findings indicated that daughters at the HBCU had less permissive attitudes about premarital sex than their counterparts at the PWI. This result was especially true for daughters of mothers with more conservative attitudes about premarital sex and who discussed such topics infrequently. Last, the combination of positive mother–daughter communication and fewer discussions about sexual topics resulted in lower levels of sexual experience among the daughters. PMID:17500604

Preferential retrotransposition in aging yeast mother cells is correlated with increased genome instability.

2015-10-01

Retrotransposon expression or mobility is increased with age in multiple species and could promote genome instability or altered gene expression during aging. However, it is unclear whether activation of retrotransposons during aging is an indirect result of global changes in chromatin and gene regulation or a result of retrotransposon-specific mechanisms. Retromobility of a marked chromosomal Ty1 retrotransposon in Saccharomyces cerevisiae was elevated in mother cells relative to their daughter cells, as determined by magnetic cell sorting of mothers and daughters. Retromobility frequencies in aging mother cells were significantly higher than those predicted by cell age and the rate of mobility in young populations, beginning when mother cells were only several generations old. New Ty1 insertions in aging mothers were more strongly correlated with gross chromosome rearrangements than in young cells and were more often at non-preferred target sites. Mother cells were more likely to have high concentrations and bright foci of Ty1 Gag-GFP than their daughter cells. Levels of extrachromosomal Ty1 cDNA were also significantly higher in aged mother cell populations than their daughter cell populations. These observations are consistent with a retrotransposon-specific mechanism that causes retrotransposition to occur preferentially in yeast mother cells as they begin to age, as opposed to activation by phenotypic changes associated with very old age. These findings will likely be relevant for understanding retrotransposons and aging in many organisms, based on similarities in regulation and consequences of retrotransposition in diverse species.

Generator separation of 103Ru//sup 103m/Rh

International Nuclear Information System (INIS)

Epperson, C.E.

1975-01-01

A generator for producing carrier-free Rh-103m was developed using a liquid extraction technique. Initially, Ru-103 chloride was converted to the sulfate by moderate fuming for 80 minutes in 1:1 sulfuric acid. The Ru-103 was then brought to its highest oxidation state with 0.2 N ceric sulfate. Ru-103 tetroxide was removed from an aqueous equilibrium solution of Ru-103/Rh-103m by three one-minute extractions into CCl 4 . The Rh-103m daughter was not extracted under these conditions. Yields of Rh-103m exceeded 90 percent theoretical. The Ru-103 removed by CCl 4 could be recovered by two hours of back-extraction into 2 M sulfuric acid containing 5 mg of sodium sulfite. A cyclic extraction system was made possible by employing sulfate media. Equilibrium Ru-103 could be repeatedly extracted and recovered, thereby producing a ''generator'' system for the production of Rh-103m. Ru-103 chloride can be converted to the sulfate and then stored for at least 38 days prior to extraction. By performing the fuming step whenever convenient, the time required to perform an extraction separation was reduced to 15 minutes. Prior treatment of glassware surfaces with dilute sulfuric acid prevented Ru-103 glass adsorption losses and made glassware much easier to decontaminate. Off-the-shelf reagent-grade CCl 4 could be used without further purification. Efforts to separate Rh-103m from Ru-103 by chromatography techniques were unsuccessful

Lúcia Margarete dos Reis

2017-08-01

Full Text Available Abstract Objective: To understand the repercussions of coexisting with the drug use in a family based on the daughter's narrative of a woman who is a multiple drugs user. Method: A case study with a family accessed in 2014, through the records of a Poison Control Center in the North of Paraná. It was used a semi-structured interview and field journal, and resources of thematic oral history to apprehend the story, from the question "How is/was for you and your family to live with a mother who is a drug user?” Results: The daughter's memories emphasized repercussions in the family context: long-term of living with drug abuse; absence or transience of the motherly figure, with rupture processes for homeless situation; cycle of parental disruption/forgiveness and continued presence and fatherly support. Final considerations: The narrative indicated a family that could be added to the process of rehabilitation and social reintegration of the female drug user.

"Sex Will Make Your Fingers Grow Thin and Then You Die": The Interplay of Culture, Myths, and Taboos on African Immigrant Mothers' Perceptions of Reproductive Health Education with Their Daughters Aged 10-14 Years.

This paper examines the convergence of culture, myths, and taboos surrounding reproductive health issues African immigrant women, living in the United States, learned during childhood in their countries of origin. We also discuss how mothers' perceptions of reproductive health education (RHE) influenced the education of their own daughters aged 10-14 years. This was a qualitative descriptive study. Data were collected via interviews and demographic survey. The sample size was 20 African immigrant mothers living in a mid-sized city in the U.S. Interviews were transcribed verbatim. Qualitative data was analyzed using qualitative content analysis. Myths and taboos related to menstruation, sexual intercourse, pregnancy, and HIV/AIDS were reported by the women interviewed. Discussion of these issues was largely taboo, and most myths the mothers learned growing up pertained to sexual intercourse, pregnancy prevention, and pregnancy termination using non-hormonal ingested substances. Myths and taboos about sexual issues are widespread in Africa and are propagated to control sexual behavior, especially that of unmarried people, particularly women. By examining these myths and taboos, we are able to somewhat contextualize the mothers' immigrant experience regarding RHE. Although myths were reported, the majority of mothers did not appear to believe them. The most significant taboo reported was sexual intercourse. This in turn led to mothers' overemphasis on abstinence for their daughters. It is also noteworthy that this sample contained mainly African women who overall were highly educated, spoke English, and could adequately navigate life in the U.S. It is unclear what the results would be if we were to examine African immigrant women with less achievements in these areas.

To examine the association and predictors of dietary intake resemblance between urban low-income African-American adolescents and their mothers. Detailed dietary data collected from 121 child-parent pairs in Chicago during fall 2003 were used. The association was assessed using correlation coefficients, kappa, and percentage of agreement, as well as logistic regression models. Overall, the association was weak as indicated by correlations and other measures. None of the mother-son correlations for nutrients and food groups were greater than 0.20. Mother-daughter pairs had stronger correlations (0.26 for energy and 0.30 for fat). The association was stronger in normal-weight mothers than in mothers with overweight or obesity. Logistic models showed that mother being a current smoker, giving child more pocket money, and allowing child to eat or purchase snacks without parental permission or presence predicted a higher probability of resemblance in undesirable eating patterns, such as high-energy, high-fat, and high-snack intakes (P<0.05). Mother-child diet association was generally weak, and varied considerably across groups and intake variables in this homogenous population. Some maternal characteristics seem to affect the association.

Unexpected suppression of anti-Fya and prevention of hemolytic disease of the fetus and newborn after administration of Rh immune globulin.

Rh immune globulin (RhIG) has been used successfully for many years for the antenatal suppression of anti-D in D- mothers carrying D+ babies to prevent hemolytic disease of the fetus and newborn. Although the mechanism of RhIG-induced immunosuppression remains unknown, a recent report (TRANSFUSION 2006;46:1316-22) has shown that women receiving RhIG produce elevated levels of transforming growth factor (TGF)β-1, a powerful immunosuppressant cytokine. It was suggested that induction of TGFβ-1 and immunosuppression may be independent of cognate antigen recognition by RhIG. Herein, we present a description of a mother and baby that supports this hypothesis. Red blood cells and serum were analyzed using saline-tube indirect antiglobulin test methods. RhIG (RhoGAM) was administered after each amniocentesis performed at 28, 31, and 36 weeks' gestation. A group A, D-(cde), K+, Fy(a-b+), MNs, Jk(a+b+) mother with no detectable anti-D had an anti-Fy(a) titer of 4096 before RhIG but only 256 after RhIG. Mother gave birth to a group O, D-(cde), Fy(a+b+) healthy baby boy having a weak-positive direct antiglobulin test with anti-Fy(a) eluted from his cells and the titer in the cord serum was 4. This case demonstrates the potential immunosuppressive properties of RhIG for down regulation of a possible clinically significant alloantibody, not anti-D, where no D+ antigen is in the circulation of the mother. The case illustrates the potential utility for using RhIG to modulate antibody levels in situations other than for classical suppression of anti-D production. Although the mechanism in this case is unknown, TGFβ-1-mediated or antibody-mediated immunosuppression to soluble nonparticulate antigens are possible mechanisms. © 2010 American Association of Blood Banks.

Socializing girls whose bodies may not align with contemporary ideals of thinness: An interpretive study of US mothers' accounts.

Ogle, Jennifer Paff; Reddy-Best, Kelly; Park, Juyeon

2017-12-01

We sought to understand how mothers of young adolescent girls who are perceived as overweight or at risk for becoming so and whose body mass indices are at the 70th percentile or higher socialize their daughters about body, weight, eating, and health. In-depth interviews were conducted with 13 US mothers, and data were analyzed using constant comparison processes. Findings revealed that mothers adopted a variety of strategies - including teaching, modeling, managing, avoiding, and comforting - to achieve varied socialization goals for their daughters. Specifically, mothers sought to help their daughters to accept the self, reject the hegemonic ideal, maintain "healthful" eating, avoid overeating/monitor the self for over-eating, engage in regular physical activity, and/or navigate stigmatizing social situations. Mothers' sometimes experienced ambivalence or uncertainty as they socialized their daughters about the body, suggesting that they may benefit from professional counseling designed to resolve this tension/hesitancy.

Full Text Available Introduction. In recent years alexithymia and attachment theory have been recognized as two parallel research lines trying to improve the information on the development and maintenance of eating disorders (EDs. However no research has analyzed these constructs among patients’ families. In this study we compared alexithymia and attachment in mothers of patients with EDs and a control group. Further, we hypothesized that mothers of daughters with EDs with insecure and unresolved states of mind will reported high levels of alexithymia. Lastly, we explored the daughters’ evaluations of maternal alexithymia.Method. 45 mothers of ED women and 48 mothers of healthy controls (N= 93 matched for age and socio-demographic variables were administered by the Toronto Alexithymia Scale-20 (TAS-20 S, while two sub-groups of ED mothers (n = 20 and non-ED ones (n = 22 were assessed by the Adult Attachment Interview (AAI. Moreover, the Observer Alexithymia Scale (OAS was administered to the daughters for evaluating maternal alexithymia.Results. Regarding alexithymia, no differences were found between ED and non-ED mothers according to the TAS-20, while ED mothers showed more unresolved AAI classifications than non-ED mothers. No correlations were found between the TAS-20 and the AAI. Lastly, ED mothers were evaluated more alexithymic by their daughters with the OAS than those in the control group, and their alexithymic traits were significantly correlated with dismissing states of mind (idealization and lack of memory in the AAIs. Discussion. Our results highlighted an interesting discrepancy among mothers with ED daughters between the low level of alexithymia provided by their self-reports and the high level of alexithymia observed by their daughters, although the OAS showed severe methodological limitations. Maternal attachment states of mind characterized by the lack of resolution of past losses could be connected to a confusing and incoherent quality of

The complexity of factors involved in anorexia nervosa (AN) and the recommendations of prominent health organizations underscore the importance of reflecting on therapeutic interventions aimed at patients' family members. To expand knowledge about the mother-daughter relationship in AN, with a focus on developing a conceptual framework that is able to improve the treatment of the disorder, reduce factors that perpetuate it and improve prognosis. A clinical method, anchored by psychodynamic references, was employed in a group of family members of patients with eating disorders. The group met weekly, and sessions were led by psychologists from the eating disorder outpatient clinic of a university hospital. Common characteristics in the mother-daughter relationship in cases of AN were identified. The issue of mutual control, the dialectic between omnipotence and impotence, and the relationship of devotion, passion and annihilation between mothers and daughters are phenomena that form the basis of AN, with a direct influence on the severity of each case and on treatment success. Our findings allowed us to identify important aspects in the mother-daughter relationship in AN, which may improve the clinical interventions aimed at treating the disorder.

To explore the infectivity of predelivery women with different modes of hepatitis B virus infections to their fetuses, eight indicators (HBsAg, anti-HBs, HBcAg, anti-HBc, HBeAg, anti-HBe, PHSA-R and anti-HBc-IgM) in serum of mother and umbilical cord blood of baby were detected. By matched pairs the result s showed that there were 170 mothers whose serum was positive for more than one indicator. The positive rate was 47.2% altogether. 15 infections modes appeared. There were 18 mothers whose serum was positive for HBsAg. Of their baby, there were 16 whose umbilical card blood was positive for HBsAg. From mother to baby, the infection rate was 88.8%(16/18). There were two babies whose umbilical cord blood was positive for HBsAg, but the serum of their mother was only positive for anti-HBc. There was one case, the umbilical cord blood of baby was positive for HBsAg, but the serum of his mother was all negative for these eight indicators. (author)

Between 10 and 14 months, infants gain the ability to learn about unfamiliar stimuli by observing others' emotional reactions to those stimuli, so called social referencing (SR). Joint processing of emotion and head/gaze direction is essential for SR. This study tested emotion and head/gaze direction effects on infants' attention via pupillometry in the period following the emergence of SR. Pupil responses of 14-to-17-month-old infants (N = 57) were measured during computerized presentations of unfamiliar objects alone, before-and-after being paired with emotional (happy, sad, fearful vs. neutral) faces gazing towards (vs. away) from objects. Additionally, the associations of infants' temperament, and parents' negative affect/depression/anxiety with infants' pupil responses were explored. Both mothers and fathers of participating infants completed questionnaires about their negative affect, depression and anxiety symptoms and their infants' negative temperament. Infants allocated more attention (larger pupils) to negative vs. neutral faces when the faces were presented alone, while they allocated less attention to objects paired with emotional vs. neutral faces independent of head/gaze direction. Sad (but not fearful) temperament predicted more attention to emotional faces. Infants' sad temperament moderated the associations of mothers' depression (but not anxiety) with infants' attention to objects. Maternal depression predicted more attention to objects paired with emotional expressions in infants low in sad temperament, while it predicted less attention in infants high in sad temperament. Fathers' depression (but not anxiety) predicted more attention to objects paired with emotional expressions independent of infants' temperament. We conclude that infants' own temperamental dispositions for sadness, and their exposure to mothers' and fathers' depressed moods may influence infants' attention to emotion-object associations in social learning contexts.

Measurements of auroral particles by means of sounding rockets of mother-daughter type

International Nuclear Information System (INIS)

Falck, A.

1985-11-01

The scientific objective of the S17 payloads was to study the ionosphere during auroral situations and especially with regards to the local fine structure and a possible separation of spatial and temporal variations of auroral phenomena. The intensities of 8 keV and 2 keV electrons have been measured from one sounding rocket launched into a breakup aurora of moderate activity and from another rocket launched into a very active substorm situation. Both the rockets were of mother-daughter type i.e. had two separated payloads. The general features in the data of different particle energies were very similar over the whole flight time of the rockets. Special events and gradients and well identifiable shapes in the particle intensities were studied to see if the intensity fluctuations obtained from two detectors in one payload or from detectors into separate payloads were time delayed. Such time delays in the particle flux intensities were obvious in both of the rocket measurements and most of these time shifts could be understood as caused by spatial variations in the particle precipitation. In parts of the rocket flights the particle intensity variations were true temporal changes. The time lags between 8 keV and 2 keV electron intensities detected in the same payload, which could be observed and were obtained by crosscorrelation analyses, were in the range less than 0.3 s and most of them less than 0.1 s. If the time differences are assumed to be caused by the velocity dispersion of the particles, the particle data reported here placed the modulation source at a distance of less than 10 000 km from the rocket position. Measurements at the S17-1 mother payload of the electric field have been compared with data of precipitating electrons and low-light-level-TV-recording of the auroral situation. An inverted-V precipitation event was observed and was associated with auroral arcs and with reversals of the measured electric field components implicating the possibility of

Traditional physical activity (PA) programs have not been effective in increasing PA in African American girls. Currently, there is limited information regarding the components of PA programs that drive participation in African American girls. The purpose of our investigation was to describe the facilitators, barriers, and components of a culturally tailored afterschool PA program that will potentially inspire the participation of African American mother-daughter dyads. Six focus groups (n=12 mother-daughter dyads; daughters, 7-10 yrs in age) were conducted between March and May 2012. Focus group semi-structured interviews were transcribed, coded, and systematically analyzed using NVivo. Mothers reported a preference for non-traditional (dancing, household chores) types of PA. While daughters preferred to participate in both dance-based and traditional types (walking, riding bikes) of PA. Participants felt that the use of a culturally tailored dance program would be appealing because it highlights the cultural and historical legacy of the African American culture. Mothers wanted programs that would allow them time to spend with their daughters. Top three dance styles that mothers wanted to participate in were African, hip-hop, and Salsa/samba, while daughters reported that they would enjoy participating in hip-hop, African, and jazz. The most common responses given for resources needed for participating in a culturally tailored afterschool dance program were the location of the program, transportation, and childcare for siblings. Our investigation highlights some cultural factors related to facilitators and barriers of PA that should be addressed in designing PA studies for African American girls and their mothers.

Topical microbicides, a female-initiated method to protect against sexually transmitted infections (STI) and pregnancy, will only be effective if found acceptable. Mothers may have an influence on acceptability and use among adolescent girls. The current study examined the communication between girls and mothers to understand the potential predictors and nature of conversations regarding surrogate microbicide products. Sexually experienced girls, 14 to 21 years, were recruited for a 6-month study examining microbicide acceptability. During face-to-face interviews, qualitative data were collected regarding communication between girls and mothers. Two independent raters coded the responses, which were organized into themes. Themes were interpreted according to the conceptual understanding of mother-daughter communication. Fifty percent of the 171 girls with codable responses had a conversation with their mother. Higher levels of indirect parental monitoring were related to being more likely to have a conversation. Concrete events related to the study (i.e. receiving phone call from the researcher, having an appointment, or seeing the product) or inquiries by mothers appeared to promote conversation. Barriers to conversation included the private nature of the information and relationship issues between the mother and daughter. Conversations often addressed issues related to girls' participation in the study, although some conversations included global issues related to sexuality. Girls may talk to their mothers about new products for STI prevention, and such conversations may provide opportunities to promote use.

Full Text Available We investigated how mothers’ parenting behaviors and personal characteristics were related to risk-taking by young children. We tested contrasting predictions from evolutionary and social role theories with the former predicting higher risk-taking by boys compared to girls and the latter predicting that mothers would influence children’s gender role development with risk-taking occurring more in children parented with higher levels of harshness (i.e., authoritarian parenting style. In our study, mothers reported their own gender roles and parenting styles as well as their children’s risk-taking and activities related to gender roles. The results were only partially consistent with the two theories, as the amount of risk-taking by sons and daughters did not differ significantly and risk-taking by daughters, but not sons, was positively related to mothers’ use of the authoritarian parenting style and the girls’ engagement in masculine activities. Risk-taking by sons was not predicted by any combination of mother-related variables. Overall, mothers who were higher in femininity used more authoritative and less authoritarian parenting styles. Theoretical implications as well as implications for predicting and reducing children’s risk-taking are discussed.

It is known that chromosomes occupy non-random positions in the cell nucleus. However, it is not clear to what extent their nuclear positions, together with their neighborhood, are conserved in daughter cells. To address specific aspects of this problem, we used the model of the chromosomes carrying ribosomal genes that are organized in clusters termed Nucleolus Organizer Regions (NORs). We compared the association of chosen NOR-bearing chromosomes (NOR-chromosomes) with nucleoli, as well as the numbers of nucleoli, in the pairs of daughter cells, and established how frequently the daughter cells had equal numbers of the homologs of certain NOR-chromosomes associated with individual nucleoli. The daughter cells typically had different numbers of nucleoli. At the same time, using immuno-FISH with probes for chromosomes 14 and 15 in HeLa cells, we found that the cell pairs with identical combinations appeared significantly more frequently than predicted by the random model. Thus, although the total number of chromosomes associated with nucleoli is variable, our data indicate that the position of the NOR-bearing chromosomes in relation to nucleoli is partly conserved through mitosis.

Familial transmission of a body-related attentional bias - An eye-tracking study in a nonclinical sample of female adolescents and their mothers.

Full Text Available Previous research indicates that body image disturbance is transmitted from mother to daughter via modeling of maternal body-related behaviors and attitudes (indirect transmission and via maternal body-related feedback (direct transmission. So far, the transmission of body-related attentional biases, which according to cognitive-behavioral theories play a prominent role in the development and maintenance of eating disorders, has not been analyzed. The current eye-tracking study applied the concepts of direct and indirect transmission to body-related attentional biases by examining body-related viewing patterns on self- and other-pictures within mother-daughter dyads.Eye movements of N = 82 participants (n = 41 healthy female adolescents, mean age 15.82 years, SD = 1.80, and their mothers, mean age 47.78 years, SD = 4.52 were recorded while looking at whole-body pictures of themselves and a control peer. Based on fixations on self-defined attractive and unattractive body areas, visual attention bias scores were calculated for mothers and daughters, representing the pattern of body-related attention allocation. Based on mothers' fixations on their own daughter's and the adolescent peer's body, a second visual attention bias score was calculated, reflecting the mothers' viewing pattern on their own daughter.Analysis of variance revealed an attentional bias for self-defined unattractive body areas in adolescents. The girls' visual attention bias score correlated significantly with their mothers' bias score, indicating indirect transmission, and with their mothers' second bias score, indicating direct transmission. Moreover, the girls' bias score correlated significantly with negative body-related feedback from their mothers.Female adolescents show a deficit-oriented attentional bias for one's own and a peer's body. The correlated body-related attention patterns imply that attentional biases might be transmitted directly and indirectly from mothers

Understanding the prevalence and correlates of decisional autonomy within specific cultural contexts is necessary to fully understand how family processes are embedded within culture. The goals of this study were to describe mothers’ and fathers’ decision-making with adolescents (M = 12.51 years, SD = 0.58; 51% female), including parent-unilateral, joint, and youth-unilateral decision-making, and to examine the socio-cultural and family characteristics associated with these different types of decision-making in 246 Mexican-origin families. Mothers reported more joint and youth-unilateral decision-making and less parent-unilateral decision-making than did fathers. Fathers reported more youth-unilateral decision-making with sons than with daughters. Further, for mothers, more traditional gender role attitudes and higher levels of mother-adolescent conflict were associated with more parent-unilateral and less joint decision-making. In contrast, for fathers, lower levels of respect values were associated with more youth-unilateral decision-making with sons, and higher levels of parent-adolescent warmth was associated with more youth-unilateral decision-making with daughters. The importance of understanding the different correlates of mothers’ and fathers’ decision-making with sons versus daughters is discussed. PMID:21484288

Prior research has identified reduced reward-related brain activation as a promising endophenotype for the early identification of adolescents with major depressive disorder (MDD). However, it is unclear whether reduced reward-related brain activation constitutes a true vulnerability for MDD. One way of studying vulnerability is through a high-risk design. Therefore, the aim of the current study was to determine whether reward-related activation of the ventral striatum is reduced in nondepressed daughters of mothers with a history of MDD (high-risk) similarly to currently depressed adolescent girls, compared with healthy controls. By directly comparing groups with a shared risk profile during differing states, we aimed to shed light on the endophenotypic nature of reduced reward processing for adolescent depression. We compared reward-related neural activity through functional magnetic resonance imaging (fMRI) between three groups of female biological offspring (N = 52) of mothers with differential MDD status: (a) currently depressed daughters of mothers with a history of MDD (MDD group; n = 14), (b) age- and socioeconomic status (SES)-matched never-depressed daughters of mothers with a history of MDD (high-risk group; n = 19), and (c) age- and SES-matched control daughters of mothers with no past or current psychopathology in either the mother or the daughter (healthy control group; n = 19). For the outcome phase of the reward task, right-sided ventral striatum activation was reduced for both currently depressed and high-risk girls compared with healthy controls. This ventral striatal activity correlated significantly with maternal depression scores. These findings provide further evidence of aberrant functioning for the United States Department of Health & Human Services, National Institutes of Health, National Institute of Mental Health (NIMH) Research Domain Criteria (RDoC)-defined domain of positive valence systems as a vulnerability factor for MDD and a

Large-scale parent-child comparison confirms a strong paternal influence on telomere length.

Telomere length is documented to have a hereditary component, and both paternal and X-linked inheritance have been proposed. We investigated blood cell telomere length in 962 individuals with an age range between 0 and 102 years. Telomere length correlations were analyzed between parent-child pairs in different age groups and between grandparent-grandchild pairs. A highly significant correlation between the father's and the child's telomere length was observed (r=0.454, Pfather-son: r=0.465, Pfather-daughter: r=0.484, Pmothers, the correlations were weaker (mother-child: r=0.148, P=0.098; mother-son: r=0.080, P=0.561; mother-daughter: r=0.297, P=0.013). A positive telomere length correlation was also observed for grandparent-grandchild pairs (r=0.272, P=0.013). Our findings indicate that fathers contribute significantly stronger to the telomere length of the offspring compared with mothers (P=0.012), but we cannot exclude a maternal influence on the daughter's telomeres. Interestingly, the father-child correlations diminished with increasing age (P=0.022), suggesting that nonheritable factors have an impact on telomere length dynamics during life.

Previous studies reported that familial factors such as birth order and mothers atopy might influence cord blood levels and development of allergies. The aim of the study was to evaluate the relationship of cord blood IgE and maternal IgE with birth order and mothers history of allergy in Albanian mother/neonate pairs. Study population represented 291 mother-infant pairs. Mothers were interviewed with a questionnaire for personal history of allergy and pregnancy history whereas serum IgE levels were determined using sandwich IRMA assay. The mean level of cIgE in neonates with detectable levels was 1.59 (n = 78). No significant difference in means of cIgE was found between first born and later born neonates (p = 0.232) and between neonates of mothers with a negative and positive history of allergy (p = 0.125). Also, no significant difference was found between means of mIgE by birth order, whereas there was a significant difference of mIgE between mothers with and without a history of allergy (p = 0.01). In a group of neonates with detectable cIgE levels, maternal IgE levels were moderately correlated with cIgE levels. Cord blood IgE is not affected by birth order and mothers history of allergy, whereas mothers IgE are affected by the history of allergy but not by birth order.

It is unclear whether a mother who is negative for hepatitis B virus surface antigen (HBsAg) but positive for hepatitis B virus (HBV) is at potential risk for mother-to-child transmission of HBV. This study, using a paired mother-teenager population, aimed to assess whether maternal HBsAg-negative HBV infection ((hn)HBI) is a significant source of child HBV infection (HBI). A follow-up study with blood collection has been conducted on the 93 mother-teenager pairs from the initial 135 pregnant woman-newborn pairs 13 years after neonatal HBV vaccination. Serological and viral markers of HBV have been tested, and phylogenetic analysis of HBV isolates has been done. The HBI prevalence was 1.9% (1 (hn)HBI/53) for teenage children of non-HBI mothers, compared with 16.7% (1 (hn)HBI/6) for those of (hn)HBI mothers and 2.9% (1 HBsAg-positive HBV infection [(hp)HBI]/34) for those of (hp)HBI mothers. Similar viral sequences have been found in one pair of whom both the mother and teenager have had (hn)HBI. In comparison with the (hp)HBI cases, those with (hn)HBI had a lower level of HBV load and a higher proportion of genotype-C strains, which were accompanied by differentiated mutations (Q129R, K141E, and Y161N) of the "a" determinant of the HBV surface gene. Our findings suggest that mother-to-teenager transmission of (hn)HBI can occur among those in the neonatal HBV vaccination program.

This study explores the relationship between a mother's attitude toward domestic violence and her children's schooling outcomes in Turkey. The sample is drawn from the 2003 Turkish Demographic and Health Survey and consists of 7,951 children within the ages of legally mandated compulsory education. A probit regression model is used to analyze the data. The results suggest that the daughters of mothers who find domestic violence acceptable are 2.6 percentage point less likely to enroll in school, all else being equal, than the daughters of mothers who do not tolerate abuse. In comparison, the schooling outcomes of male children are not statistically sensitive to the mother's attitude toward wife beating. The policy implications of the results are discussed. © The Author(s) 2014.

Third-party grooming in a captive chimpanzee group.

Science.gov (United States)

Russell, Yvan I

2010-01-01

Social grooming is ubiquitous among the captive chimpanzees at Chester Zoo. Seven individuals were chosen here for a study of third-party social dynamics. The grooming decisions of five adult males were analysed, but only insofar as they directed attention to a mother-daughter pair. Uniquely, the daughter was an unpopular and physically disabled subadult whose congenital motor impairments prevented her from grooming others effectively. The impetus for this study was the observation that some males increased their grooming towards the disabled daughter during days when the mother had a tumescent anogenital swelling (sexually attractive to males) compared to days when the mother was not tumescent (less attractive). Apparently, males were grooming the daughter with no possibility of payback (because the daughter could never "return the favour"). A "grooming rate" (avg. grooming time/hour) was calculated that showed the grooming efforts of all five males towards both mother and daughter. These rates were compared on days when (1) the mother's anogenital swelling was tumescent, and (2) days when the swelling was not tumescent. Each male showed a different pattern of behaviour. Two males groomed the daughter significantly more when the mother was tumescent. Results for all males were graphed against the quality of the social relationship between each male and the mother. Apparently, only males that had a weaker relationship to the mother groomed the daughter more when the mother was tumescent. This pattern did not exist for males with a stronger relationship to the mother. Possibly, the insecure males were using the disabled daughter as a way to curry favour with the attractive mother. If this is confirmed, then this type of triadic situation is a possible setting for indirect reciprocity to occur.

Maternal borderline personality disorder (BPD) symptoms are associated with poorer parenting. However, most studies conducted are with young children. In the current study, the authors examined associations between maternal BPD symptoms and parenting in an urban community sample of 15-to 17-year-old girls (n = 1,598) and their biological mothers. Additionally, the authors tested the impact of adolescent temperament on these associations. Mothers reported on their own psychopathology and their daughters' temperament. Adolescent girls reported on mothers' parenting methods in terms of psychological and behavioral control. Results demonstrated that maternal BPD symptoms were associated with aspects of psychological and behavioral control, even after controlling for maternal depression and alcohol use severity. After examining specific BPD components that may account for these associations, the authors found that affective/behavioral dysregulation, but not interpersonal dysregulation or identity disturbance, uniquely accounted for parenting. Adolescent temperament did not moderate these associations. BPD symptoms, particularly affective/behavioral dysregulation, are important targets when conducting parenting interventions.

Several DOE decontamination and decommissioning sites need to accurately measure thoron-daughter concentrations during decontamination efforts. Because the workers at these sites receive their dose from thoron-daughters rather than thoron gas, the thoron-daughter concentration is the measurement of interest. Some instruments currently used for making radon-daughter concentration measurements also claim the ability to measure thoron-daughter concentrations. This study evaluated the validity of those claims

The current cross-sectional study investigated and compared the associations between insight, self-stigma, and family burden among Jewish and Arab mothers of an adult son or daughter with serious mental illness (SMI) in Israel. A total of 162 Israeli mothers of a person with SMI participated in the study; 95 were Jewish (58.6%), and 67 were Arab (41.4%). Insight, self-stigma, and family burden scales were administered. Jewish mothers reported higher levels of insight into their son's or daughter's illness and reported greater family burden compared to Arab mothers. No significant differences in self-stigma scores were found between Jewish and Arab mothers. The pattern of associations between insight, self-stigma, and burden differed between Jewish and Arab mothers. Self-stigma was found to mediate the relationship between insight and burden among Jewish mothers but not among Arab mothers. Ethno-national affiliation should be taken into consideration regarding how family members conceptualize and experience mental illness, as this might affect care.

2008-11-01

The SOX2 anophthalmia syndrome is emerging as a clinically recognizable disorder that has been identified in 10-15% of individuals with bilateral anophthalmia. Extra-ocular anomalies are common. The majority of SOX2 mutations identified appear to arise de novo in probands ascertained through the presence of anophthalmia or microphthalmia. In this report, we describe two sisters with bilateral anophthalmia/microphthalmia, brain anomalies and a novel heterozygous SOX2 gene single-base pair nucleotide deletion, c.551delC, which predicts p.Pro184ArgfsX19. The hypothetical protein product is predicted to lead to haploinsufficient SOX2 function. Mosaicism for this mutation in the SOX2 gene was also identified in their clinically unaffected mother in peripheral blood DNA. Thus it cannot be assumed that all SOX2 mutations in individuals with anophthalmia/microphthalmia are de novo. Testing of parents is indicated when a SOX2 mutation is identified in a proband.

Full Text Available The purpose of this study was firstly to explore and describe the experiences of mothers who are looking after their teenage daughters’ young children. Secondly, to formulate guidelines (based on the results obtained for psychiatric nurses in assisting these mothers to mobilise resources in order to promote, maintain and restore their mental health as an integral part of health. An exploratory, descriptive, contextual and qualitative design was used and Guba’s model for ensuring trustworthiness in qualitative research was applied. The phenomenological approach was used to collect and analyse data from a sample of seven respondents who were purposively selected. Three independent themes emerged from the analysis of results: Meaning of the parenting role, life-style changes and support systems. The results further show that for these mothers the problem of teenage pregnancy and parenthood ends up being their problem. Their experiences in looking after these babies, although sometimes fulfilling and meaningful, are most of the time stressful. This has implications on their mental health. Guidelines are recommended in order to facilitate these mothers to mobilise their resources for mental health.

The performance of personal alpha dosimeters in mixed radon daughter and thoron daughter atmospheres in Ontario uranium mines is described together with monitoring developments which enable the radon daughter working level to be determined separately. The theoretical bases for continuous and integrated working level measurements based on individual and gross counts are presented in terms of the weighting factor for combining the thoron daughter working level with the radon daughter working level, and in terms of the in-growth time of the air. Implications for the determination of working level in the presence of thoron daughters are discussed

Full Text Available Background Rhesus incompatibility is a preventable cause for severe neonatal hyperbilirubinemia, hydrops fetalis and still births. The prevalence of the Rh-negative blood group among Indian woman varies from 2% - 10%. Despite declining the incidence of Rhesus incompatibility, due to availability of anti-D immunoglobulin, and improved antenatal care of the Rh-negative pregnant woman, it still accounts for a significant proportion of neonatal hyperbilirubinemia and neuro-morbidity. The prevalence of Rh-negative women having Rh-positive neonates is 60%. Objectives This study aimed to estimate the incidence of Rh iso-immunization and evaluate the outcomes of Rh iso-immunized neonates. Methods This prospective observational study was conducted in a tertiary level neonatal intensive care unit, Princess Esra hospital, Deccan college of medical sciences, Hyderabad, Telangana, India. Consecutive intramural and extramural neonates admitted to neonatal intensive care unit with the Rh-negative mother’s blood group and hyperbilirubinemia were enrolled. Neonates born to Rh+ve mothers were excluded.

The child-rearing practices of homeless and low-income housed mothers of preschool children in Head Start were compared. Overall, homeless mothers provided less learning and academic stimulation, less variety in social and cultural experiences, less warmth and affection, and a less positive physical environment for their children than did housed mothers. Mothers in both living arrangements provided more language stimulation to daughters than to sons. Implications of the findings for working with homeless families are discussed.

Objectives The FDA approved the first HPV vaccine in 2006. Research into parental decision-making and concerns about HPV vaccination highlight questions about parenting and parents’ role in the crafting of their daughters’ future sexuality. In contrast to much of this literature, we explore narratives from interviews with Cambodian mothers of HPV vaccine age-eligible daughters who experienced genocide and came to the United States as refugees. Design We conducted in-depth, in-person interviews with 25 Cambodian mothers of HPV vaccine-age eligible daughters. Interviews were conducted in Khmer and translated into English for analysis. We followed standard qualitative analysis techniques including iterative data review, multiple coders, and ‘member checking’. Five members of the research team reviewed all transcripts and two members independently coded each transcript for concepts and themes. Results Interview narratives highlight the presence of the past alongside desires for protection from uncertain futures. We turn to Quesada and colleagues’ (2011) concept structural vulnerability to outline the constraints posed by these women’s positionalities as genocide survivors when faced with making decisions in a area with which they have little direct knowledge or background: cervical cancer prevention. Conclusion Our study sheds light on the prioritization of various protective health practices, including but not exclusive to HPV vaccination, for Khmer mothers, as well as the rationalities informing decision-making regarding their daughters’ health.

Psychological outcomes in midadulthood associated with mother's child-rearing attitudes in early childhood--evidence from the 1970 British birth cohort.

Science.gov (United States)

Flouri, Eirini

2004-02-01

This study used longitudinal data from the 1970 British Cohort Study (BCS70) to examine the role of mother's child-rearing attitudes assessed when cohort members were aged 5 in children's psychological well-being (psychological functioning, psychological distress, life satisfaction and self-efficacy) at age 30. Although at the multivariate level mother's childrearing attitudes were not related to sons' psychological well-being in adult life, in daughters self-efficacy and life satisfaction at age 30 were related to mother's anti-child autonomy attitudes and mother's non-authoritarian child-rearing attitudes, respectively. In addition, mother's non-authoritarian childrearing attitudes had a protective effect against later psychological distress and low self-efficacy in daughters who had experienced significant material disadvantage in early childhood.

Sensory cilia are organelles that convey information to the cell from the extracellular environment. In vertebrates, ciliary dysfunction results in ciliopathies that in humans comprise a wide spectrum of developmental disorders. In Drosophila, sensory cilia are found only in the neurons of type I sensory organs, but ciliary dysfunction also has dramatic consequences in this organism because it impairs the mechanosensory properties of bristles and chaetae and leads to uncoordination, a crippling condition that causes lethality shortly after eclosion. The cilium is defined by the ciliary membrane, a protrusion of the cell membrane that envelops the core structure known as the axoneme, a microtubule array that extends along the cilium from the basal body. In vertebrates, basal body function requires centriolar distal and subdistal appendages and satellites. Because these structures are acquired through centriole maturation, only mother centrioles can serve as basal bodies. Here, we show that although centriole maturity traits are lacking in Drosophila, basal body fate is reserved to mother centrioles in Drosophila type I neurons. Moreover, we show that depletion of the daughter-centriole-specific protein Centrobin (CNB) enables daughter centrioles to dock on the cell membrane and to template an ectopic axoneme that, although structurally defective, protrudes out of the cell and is enveloped by a ciliary membrane. Conversely, basal body capability is inhibited in mother centrioles modified to carry CNB. These results reveal the crucial role of CNB in regulating basal body function in Drosophila ciliated sensory organs. Copyright © 2015 Elsevier Ltd. All rights reserved.

Typical signature of DNA damage in white blood cells: a pilot study on etheno adducts in Danish mother-newborn child pairs

DEFF Research Database (Denmark)

2009-01-01

The impact of DNA damage commonly thought to be involved in chronic degenerative disease causation is particularly detrimental during fetal development. Within a multicenter study, we analyzed 77 white blood cell (WBC) samples from mother-newborn child pairs to see if imprinting of DNA damage...... in mother and newborn shows a similar pattern. Two adducts 1,N(6)-ethenodeoxyadenosine (epsilondA) and 3,N(4)-ethenodeoxycytidine (epsilondC) were measured by our ultrasensitive immunoaffinity (32)P-post-labeling method. These miscoding etheno-DNA adducts are generated by the reaction of lipid peroxidation...... arising from endogenous reactive aldehydes in WBC of both mother and newborn can be reliably assessed by epsilondA and epsilondC as biomarkers. The high correlation of etheno adduct levels in mother and child WBC suggests that a typical signature of DNA damage is induced similarly in fetus and mother...

Pubertal timing and early sexual intercourse in the offspring of teenage mothers.

De Genna, Natacha M; Larkby, Cynthia; Cornelius, Marie D

Early puberty is associated with stressful family environments, early sexual intercourse, and teenage pregnancy. We examined pubertal timing and sexual debut among the 14-year-old offspring of teenage mothers. Mothers (71% Black, 29% White) were recruited as pregnant teenagers (12-18 years old). Data were collected during pregnancy and when offspring were 6, 10 and 14 years old (n = 318). Adolescents (50% male) compared the timing of their pubertal maturation to same-sex peers. There was a significant 3-way interaction effect of race, sex, and pubertal timing on sexual debut (n = 305). This effect remained significant in a model controlling for maternal age at first intercourse, substance use, exposure to trauma, authoritative parenting, and peer sexual activity (n = 255). Early maturation was associated with early sex in daughters, and may be one pathway for the inter-generational transfer of risk for teenage pregnancy among daughters of teenage mothers.

This document is a catalog of RH-TRU 72-B authorized contents by site. A content code is defined by the following components: A two-letter site abbreviation that designates the physical location of the generated/stored waste (e.g., ID for Idaho National Laboratory [INL]). The site-specific letter designations for each of the sites are provided in Table 1. A three-digit code that designates the physical and chemical form of the waste (e.g., content code 317 denotes TRU Metal Waste). For RH-TRU waste to be transported in the RH-TRU 72-B, the first number of this three-digit code is '3.' The second and third numbers of the three-digit code describe the physical and chemical form of the waste. Table 2 provides a brief description of each generic code. Content codes are further defined as subcodes by an alpha trailer after the three-digit code to allow segregation of wastes that differ in one or more parameter(s).

Few trials have aimed to promote diet and exercise behaviors in both cancer survivors and their family members and examine their associations with weight-related outcomes. We conducted a secondary analysis to examine associations between change in diet and exercise behaviors and weight-related outcomes for overweight breast cancer survivors and their overweight adult daughters in the Daughters And MothErS Against Breast Cancer (DAMES) randomized trial. The DAMES trial assessed the impact of two iteratively tailored, mailed print diet and exercise interventions against standard brochures over a 12-month period. This analysis examined change in diet and exercise behaviors and weight-related variables from baseline to post-intervention for the 50 breast cancer survivors and their adult daughters randomized to the intervention arms. To reduce the potential for type II error in this pilot, p values diet quality was uniquely related to change in BMI (β = -0.12, p = 0.082), weight (β = -0.12, p = 0.060), and waist circumference (β = -0.38, p = 0.001), whereas change in caloric intake was related to waist circumference (β = 0.21, p = 0.002). For daughters, change in caloric intake was related to change in waist circumference (β = 0.12, p = 0.055). However, change in diet quality was not associated with weight-related outcomes in daughters. Additionally, change in exercise was not associated with weight-related outcomes in mothers or daughters. Findings support mail-based and other tailored interventions for weight loss in this population, with an emphasis on diet quality for breast cancer survivors and caloric intake for their adult daughters.

Parents and Daughters in Two Novels by Arab American Authors: “Khalas, Let Her Go”

Directory of Open Access Journals (Sweden)

Full Text Available Multiple intersecting pressures bear upon immigrant parent-child, and especially immigrant mother-daughter relationships depicted in Randa Jarrar’s novel, A Map of Home, and Mohja Kahf ’s novel, The Girl in the Tangerine Scarf. Each of these novels is a Bildungsroman story, the protagonist of each being a budding artist. As the growing daughters struggle toward autonomy and parents react from complex pressures upon them, the reader gains insight on the interconnected structural and psychological factors in the intergenerational dynamics these novels portray, often with humor. The personal psychological history of the parents, as well as their displacement through immigration, in addition to anti-Arab racism in their U.S. settings and how each of these factors relates also to gender, complicate the parents’ relationships with their daughters. Through a close reading informed by postcolonial and psychological approaches, this article argues that these novels do not depict only one category of oppression but also offer multiple layers of critique.

Magnetic properties of Co-Rh and Ni-Rh nanowires

We have calculated the magnetic properties of pure Ni, Co and Rh, and alloyed Co-Rh and Ni-Rh free-standing nanowires by an ab initio method. We have found that the pure Co and Ni wires present an enhanced magnetic moment with respect to their bulk values, and we have obtained that a magnetic order appears for pure Rh wires. For concentrations up to 50% Rh, in the alloyed Ni-Rh linear chains there is an enhancement of the total magnetic moment with respect to the pure nanowires, and in the case of Co-Rh the alloying with Rh enhances the Co magnetic moment. In both systems we obtain very high Rh magnetic moments

In October 2008, Valencian Community started its human papillomavirus (HPV) vaccination schedules for 14 year-old girls. The aim of this study is to assess knowledge about HPV infection and its vaccine among the mothers of these girls, and to identify factors associated with the willingness to vaccinate their daughters. Cross-sectional study by means of a questionnaire to mothers of girls born in 1995, and attending secondary schools in the province of Valencia during 2010-2011. Cluster stratified random sample (n=1279). percentages, confidence intervals, OR, Chi-squared and multivariate logistic regression contrasts. A total of 833 (65.1%) questionnaires were completed. The results obtained showed that, 76.6% of mothers had vaccinated their daughters against HPV; 93.8% knew about the vaccine, particularly through television (71.5%); and 78.5% received positive advice from a health professional which increased the vaccination of their daughters (OR: 2.4). There was low overall knowledge about HPV infection and vaccination. Confidence of the mothers in vaccines as a preventative method increases the HPV vaccination (OR: 3.8). The first reason for refusal was the fear of adverse events (45.6%). Apparently, the media does not influence the willingness to vaccinate. It would be desirable to minimize the perception of risk of the vaccine. Positive health advice from a health professional can have a positive effect on vaccination. There is a gap between the level of knowledge and decision-making to vaccinate. Copyright © 2014 Asociación Española de Pediatría. Published by Elsevier España, S.L.U. All rights reserved.

Does a satisfactory relationship with her mother influence when a 16-year-old begins to have sex?

2012-01-01

To examine aspects of the mother-daughter relationship as perceived by the 16-year-old (cohesion, flexibility, communication, monitoring, and satisfaction with time spent together) as they relate to when the daughter began having sex. A secondary analysis using data from the National Longitudinal Survey of Youth Child (1992-2000) and Young Adult (1996-2004) surveys were analyzed (N = 1,592). Logistic regression models estimated reports of cohesion, flexibility, communication, monitoring, and satisfaction with time spent together with sexual initiation by age 16. All models controlled for the mother's sociodemographic characteristics, lack of independence due to sisters in the sample, and extended time away from mother. Girls who reported being satisfied with the amount of time spent with their mother were less likely to report early sexual initiation. In addition, these girls were three times more likely to report good communication and four times more likely to report high levels of cohesion with their mothers. Individually, in addition to satisfaction with time spent together, high levels of cohesion and good communication were also associated with lower reports of sexual initiation by age 16. The feeling of being satisfied with the time spent together appears to be a global measure of the individual dimensions of cohesion and communication. Efforts in delaying sexual initiation in adolescents need to be directed at the mother-daughter relationship. Interventions to develop these dimensions within the relationship during early adolescence, as compared to interventions when sexual activity may have already occurred, are warranted.

Why do low-income minority parents choose human papillomavirus vaccination for their daughters?

2010-10-01

To explore low-income minority parents' attitudes, intentions, and actions with regard to human papillomavirus (HPV) vaccination for their daughters. Semistructured interviews were conducted in English and Spanish with parents of girls aged 11-18 who were attending clinic visits in an urban medical center and a community health center. We assessed intention with formal scales, probed parents' attitudes regarding vaccination with open-ended questions, and reviewed medical records to determine vaccination rates. Data were analyzed using descriptive statistics and qualitative methods. Seventy-six parents participated (43% African American, 28% Latino, and 26% Caucasian). Most were mothers, had completed high school, and described themselves as religious; nearly one-half were immigrants. Intention correlated highly with receipt of the vaccine; 91% of parents intended to vaccinate their daughters against HPV, and 89% of the girls received vaccination within 12 months of the interview. Qualitative analysis revealed that most parents focused on the vaccine's potential to prevent cervical cancer. Some parents expressed concerns about unknown side effects and promotion of unsafe sexual practices, but these concerns did not hinder acceptance in most cases. The majority of the low-income minority parents surveyed viewed HPV vaccination as a way to protect their daughters from cancer, and thus chose to vaccinate their daughters.

Unattached radon daughter atoms and radon daughter equilibrium ratios in uranium mines. Final report

International Nuclear Information System (INIS)

Holaday, D.A.

1972-01-01

Uranium mines in Colorado and New Mexico were surveyed for airborne concentrations of radon (10043922) and radon daughters. A procedure for measuring individual daughters and the fraction of each existing as free atoms was developed and used for field monitoring. Samples were taken in working areas and particle counts were made. The data was analyzed to determine the ratio of radon to radon daughters as well as the ratios among the radon daughters. The author concludes that since the radon to working level ratios have not changed much in 20 years, using the ratio as the basis for estimating relative biological hazard is just as uncertain now as then. The large number of daughters present as free atoms indicate that the lung radiation doses calculated using any of the lung models need reexamination

Parental styles in the intergenerational transmission of trauma stemming from the Khmer Rouge regime in Cambodia.

Science.gov (United States)

Field, Nigel P; Muong, Sophear; Sochanvimean, Vannavuth

2013-10-01

The impact of parental styles in intergenerational transmission of trauma among mothers who survived the Khmer Rouge regime in Cambodia, in power from 1975 to 1979, and their teenaged children was examined in 2 studies. In Study 1, 46 Cambodian female high school students and their mothers were recruited. Each daughter completed anxiety and depression measures as well as assessment of her mother's role-reversing, overprotective, and rejecting parental styles, whereas the mothers completed measures of their trauma exposure during the Khmer Rouge regime and PTSD symptoms. In support of trauma transmission, the mother's PTSD symptoms were predictive of her daughter's anxiety. Moreover, the mother's role-reversing parental style was shown to mediate the relationship between her own and her daughter's symptoms. In support of their generalizability, the results were replicated in Study 2 in a Cambodian-American refugee sample comparing 15 mental health treatment-seeking mothers and their teenaged children with 17 nontreatment-seeking mother-child pairs. The implications of the findings within the larger literature on intergenerational trauma transmission stemming from genocide are discussed. © 2013 American Orthopsychiatric Association.

Single cell analysis of yeast replicative aging using a new generation of microfluidic device.

Directory of Open Access Journals (Sweden)

Full Text Available A major limitation to yeast aging study has been the inability to track mother cells and observe molecular markers during the aging process. The traditional lifespan assay relies on manual micro-manipulation to remove daughter cells from the mother, which is laborious, time consuming, and does not allow long term tracking with high resolution microscopy. Recently, we have developed a microfluidic system capable of retaining mother cells in the microfluidic chambers while removing daughter cells automatically, making it possible to observe fluorescent reporters in single cells throughout their lifespan. Here we report the development of a new generation of microfluidic device that overcomes several limitations of the previous system, making it easier to fabricate and operate, and allowing functions not possible with the previous design. The basic unit of the device consists of microfluidic channels with pensile columns that can physically trap the mother cells while allowing the removal of daughter cells automatically by the flow of the fresh media. The whole microfluidic device contains multiple independent units operating in parallel, allowing simultaneous analysis of multiple strains. Using this system, we have reproduced the lifespan curves for the known long and short-lived mutants, demonstrating the power of the device for automated lifespan measurement. Following fluorescent reporters in single mother cells throughout their lifespan, we discovered a surprising change of expression of the translation elongation factor TEF2 during aging, suggesting altered translational control in aged mother cells. Utilizing the capability of the new device to trap mother-daughter pairs, we analyzed mother-daughter inheritance and found age dependent asymmetric partitioning of a general stress response reporter between mother and daughter cells.

The human papillomavirus (HPV) vaccine could assist in reducing the cervical cancer disparity existing between Black and White women. Understanding factors influencing Black maternal intentions to vaccinate their daughter is essential in improving vaccination uptake. However, existing instruments do not comprehensively assess factors (e.g., culture) influencing maternal intentions. This paper describes the development of the Human Papillomavirus Vaccination Survey for Black Mothers with Girls Aged 9 to 12 (HPVS-BM), the first instrument to measure knowledge, attitudes, subjective norms, and cultural beliefs relating to Black maternal intentions to vaccinate their daughters aged 9 to 12 years against HPV. The items and scales were refined using content review by experts, as well as cognitive interviews and pilot testing with target audience participants. The final version of the HPVS-BM was administered to 242 Black mothers with adolescent daughters. Internal reliability was determined using Cronbach's alpha. An a priori hypothetical model was developed to determine convergent and discriminant validity. All scales of the HPVS-BM had an acceptable internal reliability of 0.70 or higher. The intention scale of HPVS-BM was significantly correlated (p factors influencing maternal intentions is warranted.

Various properties of radon and thoron daughter products are examined. Dosimeter methods and instrumentation (TLD and personal alpha dosimeters) are investigated as to performance under varying conditions such as humidity and pure or mixed atmospheric conditions. Optimized counting schemes are determined for the daughters of radon and thoron. An optimized counting scheme was experimentally examined under mine conditions. The optimization procedure takes into account the uncertainties associated with concentration, flow rate and radioactive decay. Measurements were made in two uranium mines at Elliot Lake, Ontario of the charged and unattached fractions of radon daughters in the mines. The physicochemical state of 218 Po in air was determined by measurement of rate of neutralization, diffusion coefficient and fraction born charge. Careful control of experimental conditions made it possible to obtain more precise and detailed quantitative data than previously possible

One caregiver relationship that has been neglected in caregiver depression research is the daughter-in-law. Compared with Western countries, in which those who are closer in familial relationships such as the spouse or child usually take care of the patient, in many Asian countries, the daughter-in-law often assumes the caretaker role. However, not much research has been done on how this relationship may result in different caregiver outcomes. We sought to identify whether the association between patient characteristics and caregiver depressive symptoms differs according to the familial relationship between caregiver and patient. Ninety-five daughter (n = 47) and daughter-in-law (n = 48) caregivers of dementia patients were asked to report their own depressive symptoms and patient behavioral symptoms. Patients' cognitive abilities, daily activities, and global dementia ratings were obtained. Hierarchical linear regression was employed to determine predictors of depressive symptoms. Daughters-in-law had marginally higher depressive scores. After adjusting for caregiver and patient characteristics, in both groups, greater dependency in activities of daily living and more severe and frequent behavioral symptoms predicted higher caregiver depressive scores. However, greater severity and frequency of behavioral symptoms predicted depression to a greater degree in daughters compared with daughters-in-law. Although behavioral symptoms predicted depression in both caregiver groups, the association was much stronger for daughters. This suggests that the emotional relationship between the daughter and patient exacerbates the negative effect of behavioral symptoms on caregiver depression. The familial relationship between the caregiver and dementia patient should be considered in managing caregiver stress.

calendario de la fecundidad. Plaza de la Revolución is the municipality of the lowest fertility in Cuba. The objective of this paper is to compare the reproductive history of two generations of women residents in this municipality. The generation one (mothers are 62 women born between 1942 and 1950, with ages among 57 and 64 years, that were interviewed between March 2007 and October 2008, in a precedent investigation. The generation two (daughters is integrated by 74 women born in the period 1957-1968, with ages between 45 and 56 years, interviewees between October 2013 and February 2014. The sample was intentioned selected. The selection approaches were: to choose those of the previous investigation that had daughters that resided in Plaza de la Revolución, with 45 years or more, to be close to the end of the fertile period. Her 74 daughters were interviewed applying the same interview guide that included demographics variables, of reproductive and matrimonial history, as well as related with each pregnancy, product of the conception and born alive. The reproductive history of both generations was characterized by an early age of menarche, of beginning of the sexual relationships and first marriage. The daughters postponed their first descendant’s birth regarding their mothers. The second generation had like average 1,2 less children than their progenitors and they uses more frequently the induced miscarriage and the contraception, to regulate the size of their descendant. The fertility in the adolescence was bigger in the mothers, because contrary to the daughters, they didn’t use contraception before the first gestation; neither interrupted pregnancy voluntarily. None mother had her first son with 30 years or more and 15% of the daughters did it, being evidenced generation changes in the calendar of the fertility.

cDNA clones encoding a human blood group Rh polypeptide were isolated from a human bone marrow cDNA library by using a polymerase chain reaction-amplified DNA fragment encoding the known common N-terminal region of the Rh proteins. The entire primary structure of the Rh polypeptide has been deduced from the nucleotide sequence of a 1384-base-pair-long cDNA clone. Translation of the open reading frame indicates that the Rh protein is composed of 417 amino acids, including the initiator methionine, which is removed in the mature protein, lacks a cleavable N-terminal sequence, and has no consensus site for potential N-glycosylation. The predicted molecular mass of the protein is 45,500, while that estimated for the Rh protein analyzed in NaDodSO 4 /polyacrylamide gels is in the range of 30,000-32,000. These findings suggest either that the hydrophobic Rh protein behaves abnormally on NaDodSO 4 gels or that the Rh mRNA may encode a precursor protein, which is further matured by a proteolytic cleavage of the C-terminal region of the polypeptide. Hydropathy analysis and secondary structure predictions suggest the presence of 13 membrane-spanning domains, indicating that the Rh polypeptide is highly hydrophobic and deeply buried within the phospholipid bilayer. These results suggest that the expression of the Rh gene(s) might be restricted to tissues or cell lines expressing erythroid characters

Garden of Ambivalence The Topology of the Mother-child Dyad in Grey Gardens

2012-04-01

Full Text Available The Maysles brothers’ 1975 documentary, Grey Gardens, portrays the lives of Edith Bouvier Beale and her daughter, Edith, known as Little Edie, the aunt and first cousin, respectively, of Jacqueline Bouvier Kennedy Onassis. The mother and daughter live together in their East Hampton house that is literally falling apart. As their identical names imply, the Beales share a symbiotic relationship which is reflected in every aspect of their life. I argue that Grey Gardens calls for Julia Kristeva’s insistence on abjection as a crucial struggle with “spatial ambivalence (inside/outside uncertainty” and an attempt to mark out a space in the undifferentiated field of the mother-child symbiosis. In Powers of Horror, Kristeva (1982 states, “abjection preserves what existed in the archaism of pre-objectal relationship” (p. 10. Grey Gardens portrays the topology of the mother-child dyad, which pertains to a particular spatio-temporality: where this primordial relationship is concerned, object and subject crumble, and the distinction between past and present is irrelevant.

It is of value to update radon daughter bronchial dosimetry as new information becomes available. Measurements have now been performed using hollow casts of the human bronchial tree with a larynx to determine convective or turbulent deposition in the upper airways. These measurements allow a more realistic calculation of bronchial deposition by diffusion. Particle diameters of 0.15 and 0.2 μm were used which correspond to the activity median diameters for radon daughters in both environmental and mining atmospheres. The total model incorporates Yeh/Schum bronchial morphometry, deposition of unattached and attached radon daughters, build up and decay of the daughters and mucociliary clearance. The alpha dose to target cells in the bronchial epithelium is calculated for the updated model and compared with previous calculations of bronchial dose

During 18 mo of sampling airborne radioactively at a National Priority List (open-quotes Superfundclose quotes) site in metroPOlitan Denver, Bureau of mines personnel discovered radon daughters that are not supported by the parent radon gas. We refer to them as open-quotes orphanclose quotes daughters because the parent, radon, is not present in sufficient concentration to support the measured daughter products. Measurements of the open-quotes orphanclose quotes daughters were made continuously, using the Bureau-developed radon and working-level (radon-daughter) monitors. The data showed high equilibrium ratios, ranging from 0.7 to 3.5, for long periods of time. Repeated, high-volume, 15-min grab samples were made, using the modified Tsivoglou method, to measure radon daughters, to which thoron daughters contributed 26 ± 12%. On average 28 ± 6% of the particulate activity was contributed by thoron daughters. Most samples were mixtures in which the 218 Po concentration was lower than that of 214 Pb and 214 Bi, in agreement with the high-equilibrium factors obtained from the continuous sampling data. In view of the short half-life of radon progeny, we conclude that the source of the orphan daughters is not far from the Superfund sites. The mechanism of this phenomenon is not understood at this time, but we will discuss its possible significance in evaluating population doses

This study examined whether daily variations in levels of mothers' work, home, and relationship stress were related to collaborative and oppositional qualities of mother-child conflict interactions across 1 week. Mothers reported on 1 specific conflict interaction with their 5- to 8-year-old child and their work, home, and relationship stress through online surveys each day for 7 consecutive days. Diary data from 142 mothers were analyzed in 6 multilevel models, each including within- and between-family levels of a stressor predicting collaborative or oppositional conflict qualities. Results suggested that families in the sample differed from each other, and also varied during the week, in collaborative and oppositional conflict qualities as well as stress in all 3 domains. Mothers reported a greater degree of oppositional conflict qualities on days characterized by higher perceptions of home chaos. Additionally, mothers who reported higher average levels of negativity in romantic relationships endorsed oppositional conflict qualities to a greater extent than mothers with lower relationship negativity. Two multilevel models including all 3 stressors in relation to collaborative and oppositional conflict revealed that for mothers managing multiple roles, average romantic relationship stress was the most important unique contributor to mother-child conflict qualities and daily relationship stress was particularly influential among mothers with sons compared to those with daughters. Results support the spillover hypothesis of stress within the family system and are discussed in terms of mothers' coping mechanisms and emotional engagement.

Tanning increases dramatically through the teenage years, but the family context of this health risk behavior is relatively unstudied. We conducted videotaped conversations between teenage girls (10th and 11th grade) and their mothers. We developed a coding system for discussion content and highlight findings including inadequate knowledge concerning the harms of tanning and positive views of outdoor tanning over indoor tanning, yet agreement that all tans are attractive. Many teens believed that indoor tanning is sometimes necessary to achieve the tanned look. These findings can usefully guide intervention development regarding the harms of all tanning, rather than indoor or outdoor tanning specifically. © The Author(s) 2014.

Mothers’ Academic Gender Stereotypes and Education-Related Beliefs About Sons and Daughters in African American Families

Wood, Dana; Kurtz-Costes, Beth; Okeke-Adeyanju, Ndidi; Rowley, Stephanie J.

2010-01-01

The role of African American mothers’ academic gender stereotype endorsement in shaping achievement-related expectations for and perceptions of their own children was examined. Mothers (N = 334) of 7th and 8th graders completed measures of expectations for their children’s future educational attainment, perceptions of their children’s academic competence, and academic gender stereotypes. Consistent with hypotheses, mothers held less favorable expectations for sons and perceived sons to be less academically competent than daughters. In addition, mothers reported stereotypes favoring girls over boys in academic domains; stereotype endorsement, in turn, was related to mothers’ educational expectations for and beliefs about the academic competence of their own children, even with youths’ actual achievement controlled. Negative stereotypes about the academic abilities of African American boys may create a negative feedback loop, thereby contributing to the maintenance of the gender gap in African Americans’ educational outcomes.

Passive radon daughter dosimeters

McElroy, R.G.C.; Johnson, J.R.

1986-03-01

On the basis of an extensive review of the recent literature concerning passive radon daughter dosimeters, we have reached the following conclusions: 1) Passive dosimeters for measuring radon are available and reliable. 2) There does not presently exist an acceptable passive dosimeter for radon daughters. There is little if any hope for the development of such a device in the foreseeable future. 3) We are pessimistic about the potential of 'semi-passive dosimeters' but are less firm about stating categorically that these devices cannot be developed into a useful radon daughter dosimeter. This report documents and justifies these conclusions. It does not address the question of the worker's acceptance of these devices because at the present time, no device is sufficiently advanced for this question to be meaningful. 118 refs

2010-02-01

This study assessed 1500 adolescents from the National Longitudinal Study of Youth to test the hypothesis that African American mothers differentially socialize their girls and boys. The results showed that later-born boys had fewer chores, argued more with their mothers, lived in less cognitively stimulating homes, and were not allowed to make the same decisions as were the girls or firstborn boys at the same age. The later-born boys were also lowest in achievement and highest in externalizing behaviors. Parenting differences accounted for the achievement differences but not for the externalizing behavior differences. It was concluded that the later-born boys would achieve at the same rates as their siblings if they were socialized in the same manner as their siblings.

The aim of our study was to investigate the anti-tetanus and anti-diphtheria antibody titres and the placental transfer of these antibodies in a group of vaccinated and unvaccinated mothers and their term or preterm offsprings. Anti-tetanus and anti-diphtheria toxoid IgG antibodies were measured quantitatively by ELISA in 91 infant-mother pairs. Protective concentrations of anti-tetanus and anti-diphtheria were found in 58.3 and 50% of mothers in the unvaccinated group and 94.5 and 85.5% of the mothers in the vaccinated group. Protective concentrations were found in 63.9 and 50% of cord samples, respectively, in the unvaccinated group and in 96.4 and 85.5% of cord samples, respectively, in the vaccinated group (p = 0.0001). There were no differences in the maternal and cord geometric mean concentrations (GMCs) of anti-toxoid antibodies between those who received two doses or one dose of Td. The GMCs of maternal and cord anti-tetanus and anti-diphtheria were statistically similar between preterm and term groups. Placental transfer ratios (TR) for anti-tetanus and anti-diphtheria were 175 and 150%, respectively, in the preterm group and 213 and 178%, respectively, in the term group. There was a strong correlation between maternal and cord anti-toxoid antibody levels. Maternal vaccination was the only predictor of having protective concentrations of anti-toxoid antibodies in cord blood. Vaccinating pregnant women with at least one dose of Td would confer protection for both the term and preterm infant-mother pairs. Therefore, health personnel caring for pregnant women have the responsibility to emphasize the importance of Td vaccination to avoid missed immunization opportunities.

Heparin is a structurally complex, polysaccharide anticoagulant derived from livestock, primarily porcine intestinal tissues. Low molecular weight (LMW) heparins are derived through the controlled partial depolymerization of heparin. Increased manufacturing and regulatory concerns have provided the motivation for the development of more sophisticated analytical methods for determining both their structure and pedigree. A strategy, for the comprehensive comparison of parent heparins and their LMW heparin daughters, is described that relies on the analysis of monosaccharide composition, disaccharide composition, and oligosaccharide composition. Liquid chromatography-mass spectrometry is rapid, robust, and amenable to automated processing and interpretation of both top-down and bottom-up analyses. Nuclear magnetic resonance spectroscopy provides complementary top-down information on the chirality of the uronic acid residues and glucosamine substitution. Principal component analysis (PCA) was applied to the normalized abundance of oligosaccharides, calculated in the bottom-up analysis, to show parent and daughter correlation in oligosaccharide composition. Using these approaches, six pairs of parent heparins and their daughter generic enoxaparins from two different manufacturers were comprehensively analyzed. Enoxaparin is the most widely used LMW heparin and is prepared through controlled chemical β-eliminative cleavage of porcine intestinal heparin. Lovenox{sup ®}, the innovator version of enoxaparin marketed in the US, was analyzed as a reference for the daughter LMW heparins. The results, show similarities between LMW heparins from two different manufacturers with Lovenox{sup ®}, excellent lot-to-lot consistency of products from each manufacturer, and detects a correlation between each parent heparin and daughter LMW heparin. - Highlights: • Low molecular weight heparins prepared from different heparin parents were analyzed. • An integrated analytical

Fields, D.E.; Sharp, R.D.

The Daughter Inventory Generator (DIG) code accepts a tabulation of radionuclide initially present in a waste stream, specified as amounts present either by mass or by activity, and produces a tabulation of radionuclides present after a user-specified elapsed time. This resultant radionuclide inventory characterizes wastes that have undergone daughter ingrowth during subsequent processes, such as leaching and transport, and includes daughter radionuclides that should be considered in these subsequent processes or for inclusion in a pollutant source term. Output of the DIG code also summarizes radionuclide decay constants. The DIG code was developed specifically to assist the user of the PRESTO-II methodology and code in preparing data sets and accounting for possible daughter ingrowth in wastes buried in shallow-land disposal areas. The DIG code is also useful in preparing data sets for the PRESTO-EPA code. Daughter ingrowth in buried radionuclides and in radionuclides that have been leached from the wastes and are undergoing hydrologic transport are considered, and the quantities of daughter radionuclide are calculated. Radionuclide decay constants generated by DIG and included in the DIG output are required in the PRESTO-II code input data set. The DIG accesses some subroutines written for use with the CRRIS system and accesses files containing radionuclide data compiled by D.C. Kocher. 11 refs

Maternal care of offspring is ubiquitous among primates, but its duration varies across species due to factors such as dispersal patterns and social dynamics, which influence opportunities for and potential benefits of maternal investment in older offspring, respectively. We examined mother-offspring associations in wild northern muriquis (Brachyteles hypoxanthus), in which males are philopatric, females typically disperse before puberty, and social relationships among and between males and females are egalitarian. Associations were systematically recorded between ten mothers, each with two-six offspring in the study group, and all group members from August 2003-May 2004 at the RPPN-Feliciano Miguel Abdala in Minas Gerais, Brazil. Infants of both sexes received similarly high percentages of their mothers' association time. Mothers without infants also maintained strong associations with their youngest juvenile sons. Mothers did not spend consistently more time associating with either juvenile or adult sons than daughters. Our finding of non-preferential associations between muriqui mothers and their older male offspring suggests that extended maternal investment in offspring may be of minimal value in their egalitarian society compared with its value for species living in hierarchical societies.

Gestational and developmental cues have important consequences for long-term health, behavior and adaptation to the environment. In addition, social stressors cause plastic molecular changes in the brain that underlie unique behavioral phenotypes that also modulate fitness. In the adult African cichlid, Astatotilapia burtoni, growth and social status of males are both directly regulated by social interactions in a dynamic social environment, which causes a suite of plastic changes in circuits, cells and gene transcription in the brain. We hypothesized that a possible mechanism underlying some molecular changes might be DNA methylation, a reversible modification made to cytosine nucleotides that is known to regulate gene function. Here we asked whether changes in DNA methylation of the GnRH1 gene, the central regulator of the reproductive axis, were altered during development of A. burtoni. We measured changes in methylation state of the GnRH1 gene during normal development and following the gestational and developmental stress of social crowding. We found differential DNA methylation within developing juveniles between 14-, 28- and 42-day-old. Following gestational crowding of mouth brooding mothers, we saw differential methylation and transcription of GnRH1 in their offspring. Taken together, our data provides evidence for social control of GnRH1 developmental responses to gestational cues through DNA methylation.

A liquid scintillation counting technique was applied to measure the isotope 103m Rh (half life = 56.12 min) which is difficult to detect because its γ-ray is of low energy and low emission probability. Tris-(2,4-pentanedionato)rhodium(III) (Rh(acac) 3 ) was irradiated with bremsstrahlung of accelerated 3.2 MeV electrons by LINAC. The method has given a reliable calibration curve for the determination of 103m Rh radioactivity below Rh(acac) 3 concentrations of 2 mM. The integrated cross section of 103 Rh(γ,γ') 103m Rh determined by this method was found to be 6.8±3.4 μb MeV at 3.2 MeV. (author) 8 refs.; 5 figs

Full Text Available Several evidences supported the existence of melatonin effects on reproductive system in fish. In order to investigate whether melatonin is involved in the modulation of GnRH systems in the European sea bass, we have injected melatonin (0.5 µg/g body mass in male specimens. The brain mRNA transcript levels of the three GnRH forms and the five GnRH receptors present in this species were determined by real time quantitative PCR. Our findings revealed day–night variations in the brain expression of GnRH-1, GnRH-3 and several GnRH receptors (dlGnRHR-II-1c, -2a, which exhibited higher transcript levels at mid-light compared to mid-dark phase of the photocycle. Moreover, an inhibitory effect of melatonin on the nocturnal expression of GnRH-1, GnRH-3, and GnRH receptors subtypes 1c, 2a and 2b was also demonstrated. Interestingly, the inhibitory effect of melatonin affected the expression of hypophysiotrophic GnRH forms and GnRH receptors that exhibit day–night fluctuations, suggesting that exogenous melatonin reinforce physiological mechanisms already established. These interactions between melatoninergic and GnRH systems could be mediating photoperiod effects on reproductive and other rhythmic physiological events in the European sea bass.

The electrochemical behavior of Rh(III) species in CoFe solution containing RhCl 3 , NH 4 Cl, H 3 BO 3 , CoSO 4 , FeSO 4 , saccharin, and NaLS (Na lauryl sulfate) has been investigated. The electrochemistry of Rh(III) species is influenced by each of the compounds present in CoFe plating solution, but especially by addition of saccharin and H 3 BO 3 to the RhCl 3 -NH 4 Cl solution. The nucleation and growth of Rh on GC (glassy carbon), Ru, and Cu electrodes from NH 4 Cl solution was studied using the potentiostatic current-transient methods. The results support a predominantly progressive nucleation of Rh on all three-electrode surfaces. The nucleation kinetic parameters ANo (steady state nucleation rate) and Ns (saturation nuclear number density) were found to vary with potential and are electrode-dependent in order: GC > Ru∼Cu. The electrodeposited Rh films obtained from NH 4 Cl solution and nonmagnetic CoFeRh film obtained from CoFe solution were characterized in terms of the following properties: morphology, surface roughness, crystal structure and chemical composition. The origin of light elements found in Rh and CoFeRh films (O, Cl, S, C, N) was discussed

RhIG is used worldwide to reduce the incidence of alloimmunization to D during pregnancy. We report a case of clinically significant neonatal hemolysis mediated by maternally administered RhIG. A 25-year-old, O-, primigravid mother with a negative antenatal antibody screen delivered a 6-lb 4-oz, blood group A, D+ baby girl at 36.5 weeks' gestation. Prenatal care included a dose of intramuscular RhIG at 28 weeks' gestation. At delivery, the newborn was markedly jaundiced with a total bilirubin of 6.3 mg/dL, which reached more than 20 mg/dL after 6 days. The newborn's lactate dehydrogenase (LDH) was 485 U/L (normal, newborn's direct antiglobulin test (DAT) was positive for immunoglobulin (Ig)G, with an anti-D identified by elution studies. The possibility of hemolytic disease of the newborn (HDN) due to anti-A was considered, but ultimately ruled out by the absence of anti-A1 in the eluate. The newborn's hyperbilirubinemia was adequately managed with phototherapy. Analysis of the mother's plasma 10 days postpartum revealed an anti-D titer of 8. Two months after birth, the child's laboratory studies, DAT, antibody screen, and peripheral smear were unremarkable. In the context of neonatal anemia, elevated LDH, and reticulocytosis, a positive IgG DAT with anti-D identified in the eluate suggests RhIG-mediated HDN. This appears to be a rarely reported event. © 2014 AABB.

Utilization of anti-RhD in the emergency department after blunt trauma.

Science.gov (United States)

Thorp, John M

2008-02-01

In the United States, trauma occurs in 6% to 7% of pregnancies. Its severity may range from critical injuries where the mother's life is at risk, to apparently minor injuries, which might not be associated with any worrisome symptoms. One of the risks associated with a traumatic event is fetomaternal hemorrhage--the transfer of fetal blood cells into the maternal circulation. If the maternal blood type is rhesus negative and the fetus is rhesus positive, even a small amount of blood can cause the mother to develop antibodies against the fetal Rho D antigen, thus becoming sensitized. In subsequent pregnancies, this can lead to hemolytic disease of the fetus or newborn, which, if severe, is associated with total body edema, hepatosplenomegaly and heart failure, and intrauterine death. Although there are no published studies specific to the US population, poor awareness of the risk of sensitization following trauma and underutilization of anti-RhD in the emergency department has been reported in countries such as Canada and the United Kingdom. This article reminds caregivers of the risk of rhesus sensitization following blunt trauma, in order that they can administer anti-RhD appropriately and hemolytic disease of the fetus or newborn can be prevented.

Objective Few studies have investigated potential gender differences in the genetic and environmental influences on the prospective associations between parent-child conflict and later depression, a notable gap given substantial gender differences in rates of depression and suggestive evidence of differences in the etiology of depression among females and males. To fill this gap, we evaluated whether the prospective relationship between parent-child conflict and major depressive disorder (MDD) symptoms varied as a function of parent-child gender composition. Method A combined twin and adoption sample was used (53% female; 85% European ancestry), containing 1,627 adolescent sibling pairs (789 monozygotic twin pairs, 594 dizygotic/full-biological pairs, 244 genetically unrelated pairs) with assessments at two time points in adolescence (ages ~15 to ~18). Results Prospective associations between parent-child conflict and subsequent adolescent depression were explained predominately through common genetic influences for mother-daughter and mother-son pairs, but less so for father-daughter and father-son pairs. Conclusion Processes of gene-environment correlation involved in the prospective associations between parent-child conflict and later adolescent depression appear to be less relevant to father-child relationships in comparison to mother-child relationships. Notably, results did not show parent-child conflict was more relevant to the etiology of MDD for girls than boys; gender differences in depression do not appear to be due to differences in the associations between parent-child conflict and child depression.

Health hazards due to radon and its daughters

The health hazards liked to radon and its daughters have become a matter of great public concern. When inhaled, a fraction of radon is dissolved into the lung fluid, from where it is transported to other parts of the body. The radiation damage is caused to the lungs due to alpha decay of radon during its transit time within the respiratory tract. Radon daughters are found to be even more dangerous than radon itself. These daughters attach themselves to dust particles present in the air. Some of the aerosols so produced enter the lungs and enter the blood stream. It has now been confirmed that radon and its daughters contribute about 70% of the internal dose received by an individual from natural radiation sources. The danger of indoor radon and its daughters is even higher for energy-saving houses and those having poor ventilation systems. This paper briefly describes the health hazards due to radon and its daughters. Different methods employed for the measurement of concentrations of radon and their daughters are described. The experience gained from the nation-wide surveys carried out in different countries is also given. (author). 18 refs, 3 figs, 1 tab

Data exists showing that seasonal changes in the innervations of GnRH cells in the hypothalamus and functions of some neural systems affecting GnRH neurons are associated with GnRH release in ewes. Consequently, we put the question as to how the expression of GnRH gene and GnRH-R gene in the hypothalamus and GnRH-R gene in the anterior pituitary gland is reflected with LH secretion in anestrous and luteal phase ewes. Analysis of GnRH gene expression by RT-PCR in anestrous ewes indicated comparable levels of GnRH mRNA in the preoptic area, anterior and ventromedial hypothalamus. GnRH-R mRNA at different concentrations was found throughout the preoptic area, anterior and ventromedial hypothalamus, stalk/median eminence and in the anterior pituitary gland. The highest GnRH-R mRNA levels were detected in the stalk/median eminence and in the anterior pituitary gland. During the luteal phase of the estrous cycle in ewes, the levels of GnRH mRNA and GnRH-R mRNA in all structures were significantly higher than in anestrous ewes. Also LH concentrations in blood plasma of luteal phase ewes were significantly higher than those of anestrous ewes. In conclusion, results from this study suggest that low expression of the GnRH and GnRH-R genes in the hypothalamus and of the GnRH-R gene in the anterior pituitary gland, amongst others, may be responsible for a decrease in LH secretion and the anovulatory state in ewes during the long photoperiod.

Estimating dispersal rates of Steller sea lion (Eumetopias jubatus mother-pup pairs from a natal rookery using mark-resight data.

Directory of Open Access Journals (Sweden)

Carey E Kuhn

Full Text Available To monitor population trends of Steller sea lions (Eumetopias jubatus in Alaska, newborn pups are counted during aerial surveys. These surveys are scheduled to occur after the majority of pups are born, but before pups begin to spend significant time in the water. Some studies have reported dispersal of mother-pup pairs away from breeding beaches during the pupping season (July, which may influence survey results. Using a multistate mark-recapture model with state uncertainty, we estimated the amount of dispersal during the pupping season based on observations of permanently marked sea lions. Research was conducted at land-based observation sites on Marmot Island, Alaska, between 2000 and 2013. Both marked adult females with dependent pups and marked pups were observed at two rookery beaches from May to July. Cumulative dispersal rates were minimal (< 1% prior to the planned start of the aerial survey (23 June and increased to 11.2% by the planned survey completion date (10 July. The increased cumulative dispersal rate during the remainder of the observation period (end of July suggests potential bias in surveys that occur beyond 10 July, however surveys past this date are rare (< 10% between 1973 and 2016. As a result, movements of mother-pup pairs during the pupping season are not likely to influence aerial survey estimates.

Removal of radon daughters from indoor air

International Nuclear Information System (INIS)

Jonassen, N.

1985-01-01

The internal radiological exposure of the general population is largely due to the airborne daughter products of radon and thoron, which are found in two states, attached to aerosols or unattached, of which the latter species according to several dose models have the highest radiological dose efficiency of the two. The radon daughters may be removed from indoor air by a series of processes like ventilation, filtration, plateout, and electrostatic deposition. Ventilation (with radon-free air) is, on the one hand, a very effective measure, but usually involves introduction of colder air, in variance with energy-saving efforts. Internal filtration will not affect the radon concentration but may reduce the level of daughter activities, roughly inversely proportional to the filtration rate. At the same time, however, filtration may also change the aerosol distribution and concentration of the air and, consequently, the partitioning of the radon daughters between the attached and unattached state. This, in turn, influences the rate of deposition of radon daughters both by diffusional plateout and as an effect of an electric field. Experiments are reported demonstrating reductions in the airborne potential alpha energy by factors of 4 to 5 by use of filtration rates of 3-4 times per hour. In case of low aerosol concentrations, however, the corresponding reduction in radiological dose to critical parts of the respiratory tract may be much smaller, due to the shift toward higher fractions of the radon daughters being in the unattached state caused by the filtration. The possibility of using electrostatic deposition of radon daughters is also discussed

Numerous density functional theory calculations have been performed to investigate the complete mechanisms of methanol dehydrogenation on Rh(100) and Rh(110) surfaces. The adsorption properties of relevant species were discussed in details. In addition, a comprehensive reaction network including four reaction pathways was built and analyzed. It is found that the initial Osbnd H bond scission of CH3OH seems to be more favorable than Csbnd H bond cleavage on both Rh(100) and Rh(110) surfaces from the perspective of activation barriers. It is also concluded that path1 (CH3OH → CH3O → CH2O → CHO → CO) is the predominant pathway on both Rh(100) and Rh (110) surfaces. On the whole, in most of the dehydrogenation reactions investigated, the energy barriers on Rh(100) are lower than those on Rh (110). Remarkable differences in the activity and predominant reaction pathway on Rh(100), Rh(110) and Rh(111) indicate that the dehydrogenation of methanol might be structure-sensitive.

A M r 32,000 integral membrane protein has previously been identified on erythrocytes bearing the Rh(D) antigen and is thought to contain the antigenic variations responsible for the different Rh phenotypes. To study it on a biochemical level, a simple large-scale method was developed to purify the M r 32,000 Rh protein from multiple units of Rh(D)-positive and -negative blood. Erythrocyte membrane vesicles were solubilized in NaDodSO 4 , and a tracer of immunoprecipitated 125 I surface-labeled Rh protein was added. The Rh protein was purified to homogeneity by hydroxylapatite chromatography followed by preparative NaDodSO 4 /PAGE. Approximately 25 nmol of pure Rh protein was recovered from each unit of Rh(D)-positive and -negative blood. Rh protein purified from both Rh phenotypes appeared similar by one-dimensional NaDodSO 4 /PAGE, and the N-terminal amino acid sequences for the first 20 residues were identical. Rh proteins purified from Rh(D)-positive and -negative blood were compared by two-dimensional iodopeptide mapping after 125 I-labeling and α-chymotrypsin digestion. The peptide maps were very similar. These data indicate that a similar core Rh protein exists in both Rh(D)-positive and -negative erythrocytes, and the Rh proteins from erythrocytes with different Rh phenotypes contain distinct structural polymorphisms

Element-selective magnetic properties of new core-shell bimetallic MRh (M=Fe or Co) nanoparticles (NP{sub S}) of 50/50 composition with either M-Rh or Rh-M core/shell order and an average diameter of {approx}2 nm have been investigated by X-ray Absorption Spectroscopy (XANES) and X-Ray Magnetic Circular Dichroism (XMCD) technique. XANES spectra at the Rh L{sub 2,3} edges exhibit the same characteristic features for all systems having the Rh metal enriched shell. XMCD experiments at the same edges have shown that 4d states of Rh atoms acquire a magnetic moment as a result of hybridization with iron or cobalt 3d states. As expected the value of this induced moment depends on the 3d transition metal and on the core/shell chemical order in the nanoparticle.

A field method for monitoring thoron-daughter working level

1975-01-01

The concept of working level, generally used for radon daughters, has been extended to the daughter products of thoron. Accordingly, thorondaughter working level (TWL) has been defined as the alpha energy released from the ultimate decay of 100 pCi/1 each of the short-lived decay products of thoron. In order to facilitate the evaluation of inhalation hazard in thorium handling areas, a simple field method has been suggested to measure the thoron-daughter working level. A comparison of the potential alpha energies from radon-daughters and that from thoron-daughter is included. (K.B.)

The majority of adolescent girls fail to meet public health guidelines for physical activity. Engaging mothers in the promotion of physical activity for their daughters may be an important strategy to facilitate behaviour change. The aim of this study was to use the behaviour change wheel (BCW) framework to design the components of an intervention to improve adolescent girls' physical activity. Cross-sectional study to inform intervention development. The BCW framework was used to (1) understand the behaviour, (2) identify intervention functions and (3) select content and implementation options. A circular development process was undertaken by the research team to collectively design the intervention in accordance with the steps recommended by the BCW. The BCW design process resulted in the selection of six intervention functions (education, persuasion, incentivization, training, modelling, enablement) and 18 behaviour change techniques delivered via group-based, face-to-face mode. Behaviour change technique groupings include: goals and planning; feedback and monitoring; social support; shaping knowledge; natural consequences; comparison of behaviour; associations; comparison of outcomes; reward and threat; identity; and, self-belief. The BCW process allowed an in-depth consideration of the target behaviours and provided a systematic framework for developing the intervention. The feasibility and preliminary efficacy of the programme will be examined. Copyright © 2018 The Royal Society for Public Health. Published by Elsevier Ltd. All rights reserved.

Eighty-seven mothers and their four-year-old children from Eastern Turkey (N = 32 pairs), Western Turkey (N = 30 pairs) and the USA (N = 25 pairs) participated in a study of mother-child memory talk as a reflection of mothers' self construal, in view of differences in the function of memory talk across cultures. Mother-child pairs were audio-recorded while talking about shared past and anticipated future events. Mothers completed the Balanced Integration-Differentiation questionnaire measure of self-construal and were scored as high or low on individuation and relatedness orientations. Mothers' memory and future talk showed similar patterns of cultural differences: American mothers provided the most voluminous, descriptive and elaborative talk, while Eastern Turkish mothers showed the highest level of repetitiveness, and Western Turkish mothers' talk fell in between. Children's memory talk was similar across cultures. In all cultures, mothers who scored high on both individuation and relatedness (balanced self-construal subtype) engaged in more voluminous and contexted memory talk, and individuation was associated with more elaborative talk about future events. Results are discussed in light of literature on cultural differences in self-construal and memory function.

Full Text Available Abstract Background Antenatal care (ANC has been recognised as a way to improve health outcomes for pregnant women and their babies. However, only 29% of pregnant women receive the recommended four antenatal visits in Nepal but reasons for such low utilisation are poorly understood. As in many countries of South Asia, mothers-in-law play a crucial role in the decisions around accessing health care facilities and providers. This paper aims to explore the mother-in-law's role in (a her daughter-in-law's ANC uptake; and (b the decision-making process about using ANC services in Nepal. Methods In-depth interviews were conducted with 30 purposively selected antenatal or postnatal mothers (half users, half non-users of ANC, 10 husbands and 10 mothers-in-law in two different (urban and rural communities. Results Our findings suggest that mothers-in-law sometime have a positive influence, for example when encouraging women to seek ANC, but more often it is negative. Like many rural women of their generation, all mothers-in-law in this study were illiterate and most had not used ANC themselves. The main factors leading mothers-in-law not to support/encourage ANC check ups were expectations regarding pregnant women fulfilling their household duties, perceptions that ANC was not beneficial based largely on their own past experiences, the scarcity of resources under their control and power relations between mothers-in-law and daughters-in-law. Individual knowledge and social class of the mothers-in-law of users and non-users differed significantly, which is likely to have had an effect on their perceptions of the benefits of ANC. Conclusion Mothers-in-law have a strong influence on the uptake of ANC in Nepal. Understanding their role is important if we are to design and target effective community-based health promotion interventions. Health promotion and educational interventions to improve the use of ANC should target women, husbands and family members

2013-01-01

Highlights: ► The effect of humidity on the motion behavior of Si(1 0 0)/SiO 2 pair was clarified. ► With increase in humidity, adhesion force increases slowly firstly, then sharply. ► With increase in humidity, friction force increases sharply firstly, then slowly. ► The wear degree of Si is relative to the physical state of absorbed water film. ► The tribochemical reaction of Si(1 0 0) in humid air was verified by ToF-SIMS. - Abstract: With an atomic force microscopy, the humidity-dependent nanotribology behaviors of Si(1 0 0) against SiO 2 microsphere were investigated while the relative movement translated from stick to slip. The relative humidity RH of air exhibits a strong effect on the motion behavior of Si(1 0 0)/SiO 2 pair. With the increase in RH, relative movement of Si(1 0 0)/SiO 2 pair is easier to keep into stick state, namely, the relative slip becomes more difficult to occur in a higher humidity range. The adhesion F a will increase with the increase in RH in the given humidity range. In the low RH range ( a increases very slowly. However, in relative higher RH range (>20%), F a increases very sharply once ‘liquid-like’ adsorbed water layer forms, because it increases the capillary force. The initial friction forces F t of Si(1 0 0)/SiO 2 pair also increase with the increase in RH in the given humidity range. However, different from F a , it increases sharply in the low RH range ( 30%). During the cyclic friction process, under the higher RH, relative stable tangential force is easier to be observed at higher displacement amplitude, here, the relative movement usually keeps into stick state. With the increase in RH, the surface damage of Si(1 0 0) transforms from mechanical deformation (forming hillock) to tribochemical wear (material removal). The tribochemical wear is sensitive to the absorbed water film with ‘solid-like’ structure, here, the wear volume increases drastically in this RH range (<20%); further increase of wear is

Full Text Available In the title compound, [Rh2(C8H8NO4(C8H7N], the four acetamidate ligands bridging the dirhodium core are arranged in a 2,2-trans manner. One RhII atom is five-coordinate, in a distorted pyramidal geometry, while the other is six-coordinate, with a disorted octahedral geometry. For the six-coordinate RhII atom, the axial nitrile ligand shows a non-linear Rh–nitrile coordination with an Rh—N—C bond angle of 166.4 (4° and a nitrile N—C bond length of 1.138 (6 Å. Each unique RhII atom is coordinated by a trans pair of N atoms and a trans pair of O atoms from the four acetamide ligands. The Neq—Rh—Rh—Oeq torsion angles on the acetamide bridge varies between 12.55 (11 and 14.04 (8°. In the crystal, the 3-methylbenzonitrile ring shows a π–π interaction with an inversion-related equivalent [interplanar spacing = 3.360 (6 Å]. A phenyl ring on one of the acetamide ligands also has a face-to-face π–π interaction with an inversion-related equivalent [interplanar spacing = 3.416 (5 Å].

Prenatal and newborn immunoglobulin levels from mother-child pairs and risk of autism spectrum disorders

Full Text Available Background. An etiological role for immune factors operating during early brain development in children with autism spectrum disorders (ASD has not yet been established. A major obstacle has been the lack of early biologic specimens that can be linked to later diagnosis. In a prior study, we found lower risk of ASD associated with higher levels of maternally-derived total IgG and Toxoplasmosis gondii (Toxo IgG in newborn blood spot specimens from children later diagnosed with ASD compared to population controls.Methods. We obtained maternal mid-gestational serum specimens and newborn screening blood spots from the California Genetics Disease Screening Program (GDSP for linked mother-baby pairs for 84 children with ASD and 49 children with developmental delay but not ASD (DD identified from California Department of Developmental Services records and for 159 population controls sampled from birth certificates. Immunoglobulin levels in maternal and newborn specimens were measured by solid phase immunoassays and analyzed in logistic regression models for total IgG, total IgM, and Toxo IgG, and, for maternal specimens only, Toxo IgM. Correlations between maternal and newborn ranked values were evaluated.Results. In both maternal and newborn specimens, we found significantly lower risk of ASD associated with higher levels of Toxo IgG. In addition, point estimates for all comparisons were <1.0 suggesting an overall pattern of lower immunoglobulin levels associated with higher ASD risk but most did not reach statistical significance. We did not find differences in maternal or newborn specimens comparing children with DD to controls. Discussion. These results are consistent with evidence from our prior study and other published reports indicating that immune factors during early neurodevelopment may be etiologically relevant to ASD. Lowered immunoglobulin levels may represent suboptimal function of the maternal immune system or reduced maternal exposure

Full Text Available Chinese culture and tradition stand in direct opposition to American and European cultures. Chinese children must live according to the principles of metaconfucianism from an early age. Failure to do so threatens social ostracism. Amy Chua in her autobiographical novel Battle Hymn of the Tiger Mother describes the education of her two daughters living in America according to the principles present in China. The educational methods used by Chua are considered controversial by western parents. The author made an attempt to explain the motives of Asian mothers.

Radon and its daughters in vivo

International Nuclear Information System (INIS)

Rundo, J.

1983-01-01

Some aspects of the behavior of radon and its short-lived daughters in vivo are described and a relationship between the radon exhalation rate and time after a meal is demonstrated. A major but short-lived postprandial increase in the exhalation rate of radon produced from skeletally-deposited radium was observed and a similar effect in exhalation rate of environmental radon by persons containing no radium was noted. Persons living in houses with elevated concentrations of radon may contain sufficient activity for its detection by external gamma-ray counting. Some of the activity observed is due to inhaled daughter-products in the chest, and some to daughter-products associated with and produced by the decay of radon throughout the body. 3 references, 8 figures.

Full Text Available Objective: To compare long GnRH agonist with GnRH antagonist protocol in poor responders. Materials and Methods: Medical charts of 531 poor responder women undergoing in-vitro fertilization (IVF cycle at Zeynep Kamil Maternity and Children’s Hospital, IVF Center were retrospectively analysed. Those who received at least 300 IU/daily gonadotropin and had ≤3 oocytes retrieved were enrolled in the study. Poor responders were categorized into two groups as those who received long GnRH agonist or GnRH antagonist regimen. Results: Treatment duration and total gonadotropin dosage were significantly higher in women undergoing the long GnRH agonist regimen compared with the GnRH antagonist regimen (p<0.001 for both. Although the number of total and mature oocytes retrieved was similar between the groups, good quality embryos were found to be higher in the GnRH antagonist regimen. The day of embryo transfer and number of transferred embryos were similar in the groups. No statistically significant differences were detected in pregnancy (10.5% vs 14.1%, clinical pregnancy (7.7% vs 10.6% and early pregnancy loss rates (27.2% vs 35% between the groups. Conclusion: GnRH antagonist regimen may be preferable to long GnRH regimen as it could decrease the cost and treatment duration in poor responders.

{sup 103}Rh nuclear magnetic resonance (NMR) measurements have been performed in the superconductor Rh{sub 17}S{sub 15} with the transition temperature T{sub C}=5.4 K. The observed {sup 103}Rh-NMR spectrum shows an asymmetric shape with several peaks, reflecting the local symmetry around each Rh site. We have identified the observed NMR lines corresponding to four different Rh sites and obtained the temperature (T) dependence of the Knight shift of 24m site. The isotropic part of the Knight shift K{sub iso} decreases with decreasing T, indicating the existence of the electron correlation in Rh{sub 17}S{sub 15}. In the superconducting state, the resonance lines shift to higher frequencies owing to a decrease of the spin part of the Knight shift with negative hyperfine coupling.

RH-TRU Waste Content Codes

Energy Technology Data Exchange (ETDEWEB)

Washington TRU Solutions

2007-07-01

The Remote-Handled Transuranic (RH-TRU) Content Codes (RH-TRUCON) document describes the inventory of RH-TRU waste within the transportation parameters specified by the Remote-Handled Transuranic Waste Authorized Methods for Payload Control (RH-TRAMPAC).1 The RH-TRAMPAC defines the allowable payload for the RH-TRU 72-B. This document is a catalog of RH-TRU 72-B authorized contents by site. A content code is defined by the following components: • A two-letter site abbreviation that designates the physical location of the generated/stored waste (e.g., ID for Idaho National Laboratory [INL]). The site-specific letter designations for each of the sites are provided in Table 1. • A three-digit code that designates the physical and chemical form of the waste (e.g., content code 317 denotes TRU Metal Waste). For RH-TRU waste to be transported in the RH-TRU 72-B, the first number of this three-digit code is “3.” The second and third numbers of the three-digit code describe the physical and chemical form of the waste. Table 2 provides a brief description of each generic code. Content codes are further defined as subcodes by an alpha trailer after the three-digit code to allow segregation of wastes that differ in one or more parameter(s). For example, the alpha trailers of the subcodes ID 322A and ID 322B may be used to differentiate between waste packaging configurations. As detailed in the RH-TRAMPAC, compliance with flammable gas limits may be demonstrated through the evaluation of compliance with either a decay heat limit or flammable gas generation rate (FGGR) limit per container specified in approved content codes. As applicable, if a container meets the watt*year criteria specified by the RH-TRAMPAC, the decay heat limits based on the dose-dependent G value may be used as specified in an approved content code. If a site implements the administrative controls outlined in the RH-TRAMPAC and Appendix 2.4 of the RH-TRU Payload Appendices, the decay heat or FGGR

Maternal HIV Serostatus, Mother–Daughter Sexual Risk Communication and Adolescent HIV Risk Beliefs and Intentions

Daughters of HIV-positive women are often exposed to the same factors that placed their mothers at risk. This cross-sectional study (N = 176 dyads) examined HIV status, parent-teen sexual risk communication (PTSRC), and daughters’ abstinence and condom use beliefs and intentions. Maternal HIV status was not associated with PTSRC. Path analyses show that maternal depression was associated with PTSRC behavioral and normative beliefs; relationship satisfaction was associated with PTSRC normative and control beliefs. Control beliefs were solely predictive of maternal PTSRC intention. PTSRC was associated with adolescent behavioral and normative beliefs. Abstinence beliefs were associated with abstinence intentions; condom beliefs were associated with condom use intentions. Relationship satisfaction was associated with adolescent control beliefs about both abstinence and condom use. There is a need for interventions that help HIV-positive mothers recognize their daughter’s HIV risk and provide them with relationship building and parent process skills to help reduce these risks.

Control of radon daughters in underground mining

International Nuclear Information System (INIS)

Swent, L.W.

1983-01-01

This paper discusses technical developments that may enable uranium mine operators to improve engineering controls of radon daughter concentrations in mines, and developments in regulatory controls. The origin of radon daughters in underground mines is explained. The procedure for sampling and determining the concentration of alpha radiation in sampled air is reviewed. The principal technical development in the last few years has been the perfection and use of a class of meters which determine radon daughter concentrations in an air sample in a matter of two or three minutes without any aging period. A number of underground uranium mine operators are now using ''instant'' type meters and the Mine Safety and Health Administration (MSHA) has approved their use in a number of mines. The difficulty experienced by uranium mine operators in complying with a MSHA regulation which requires that no person be exposed to radon daughter concentrations exceeding 1 Working Level (WL) in any active working place is discussed

Gonadotropin-releasing hormone (GnRH) neurons are a nexus of fertility regulation. We used translating ribosome affinity purification coupled with RNA sequencing to examine messenger RNAs of GnRH neurons in adult intact and gonadectomized (GDX) male and female mice. GnRH neuron ribosomes were tagged with green fluorescent protein (GFP) and GFP-labeled polysomes isolated by immunoprecipitation, producing one RNA fraction enhanced for GnRH neuron transcripts and one RNA fraction depleted. Complementary DNA libraries were created from each fraction and 50-base, paired-end sequencing done and differential expression (enhanced fraction/depleted fraction) determined with a threshold of >1.5- or <0.66-fold (false discovery rate P ≤ 0.05). A core of ∼840 genes was differentially expressed in GnRH neurons in all treatments, including enrichment for Gnrh1 (∼40-fold), and genes critical for GnRH neuron and/or gonadotrope development. In contrast, non-neuronal transcripts were not enriched or were de-enriched. Several epithelial markers were also enriched, consistent with the olfactory epithelial origins of GnRH neurons. Interestingly, many synaptic transmission pathways were de-enriched, in accordance with relatively low innervation of GnRH neurons. The most striking difference between intact and GDX mice of both sexes was a marked downregulation of genes associated with oxidative phosphorylation and upregulation of glucose transporters in GnRH neurons from GDX mice. This may suggest that GnRH neurons switch to an alternate fuel to increase adenosine triphosphate production in the absence of negative feedback when GnRH release is elevated. Knowledge of the GnRH neuron translatome and its regulation can guide functional studies and can be extended to disease states, such as polycystic ovary syndrome.

New ICRP recommendations on occupational limits for radon daughters

International Nuclear Information System (INIS)

Jacobi, W.

1981-01-01

The ICRP has recommended in 1959 for the first time a maximum permissible concentration (MPC) for the occupational exposure to radon and its short-lived daughters. Since this time more realistic dosimetric models for radon daughters have been developed. Taking into account epidemiological and new dosimetric findings the ICRP has adopted in March this year new recommendations on occupational limits for inhalation of 222 Rn, 220 Rn and their short-lived daughters. This report will be published this year as ICRP Publication 32 (ICRP 1981). The recommended limits for radon daughters were derived from the basic dose and risk limits as they were proposed by ICRP in its new basic recommendations (ICRP Publ. 26, 1977). In the following this basic system of dose limitation is shortly outlined before the special recommendations for radon daughters are described

Correlation between parent and daughter element concentrations as a means of valuing isochrons of igneous rocks

International Nuclear Information System (INIS)

Wetzel, K.

1989-01-01

The question whether a series of samples from an igneous rock can be attributed to an isochron for radiogeochronological dating or for determining the initial isotope ratio of the daughter element of the radioactive decay can be valued by investigating the correlation between the concentrations 1 c and 2 c of mother ( 1 c) and daughter element ( 2 c). The slope of the regression line in a lg 1 c to lg 2 c diagram is given by 1 D - 1/ 2 D - 1 or 1 D - 1/ 2 D - 1 · 2 D/ 1 D, where 1 D and 2 D are the solid-liquid distribution coefficients of parent and daughter element, if the concentration patterns are ruled by fractional crystallization or by partial melting, respectively. The agreement between experimentally found slopes and those calculated from distribution coefficients thus gives additional evidence whether or not the isochron reflects a magma solidification or magma generation age, respectively. The method is discussed for the Rb-Sr-, Sm-Nd-, La-Ce-, La-Ba- and K-Ca-geochronometers, using distribution coefficients calculated on the basis of a global model of the generation of the most abundant continental igneous rocks. The application on Rb-Sr-isochrons of a series of various granites of the Erzgebirge and the Saxonian Granulite Massif in the Southern Part of the GDR reveals new evidence of postmagmatic autosomatosis having altered the chemical composition of the Younger granites of the Western Ore Mountains (Erzgebirge).

Due to intestinal cytochrome P450 (CYP450)-mediated metabolism and P-glycoprotein (P-gp) efflux, poor oral bioavailability hinders ginsenoside-Rh1 (Rh1) and ginsenoside-Rh2 (Rh2) from clinical application. In this study, Rh1 and Rh2 were incorporated into two self-microemulsions (SME-1 and SME-2) to improve oral bioavailability. SME-1 contained both CYP450 and P-gp inhibitory excipients while SME-2 only consisted of P-gp inhibitory excipients. Results for release, cellular uptake, transport, and lymph node distribution demonstrated no significant difference between either self-microemulsions in vivo, but were elevated significantly in comparison to the free drug. The pharmaceutical profiles in vivo showed that the bioavailability of Rh1 in SME-1 (33.25%) was significantly higher than that in either SME-2 (21.28%) or free drug (12.92%). There was no significant difference in bioavailability for Rh2 between SME-1 (48.69%) or SME-2 (41.73%), although they both had remarkable increase in comparison to free drug (15.02%). We confirmed that SME containing CYP450 and P-gp inhibitory excipient could distinctively improve the oral availabilities of Rh1 compared to free drug or SME containing P-gp inhibitory excipient. No notable increase was observed between either SME for Rh2, suggesting that Rh2 undergoes P-gp-mediated efflux, but may not undergo distinct CYP450-mediated metabolism.

Strong, J.C.; Laidlaw, A.J.; O'Riordan, M.C.

1975-11-01

The results of surveys of radon and radon daughter concentrations in a large number of mines, other than coal mines, in Great Britain are presented. Measurement methods are described, and estimates of the average radon daughter concentrations are given. A comparison is made between the results of radon and radon daughter determination. The radon daughter exposure of about 40% of the non-coal miners covered by a survey in 1973 was estimated to be above the recommended limit of 4 WLM in a year. Recommendations were made for reducing this exposure and for radiological surveillance. A follow-up survey shows some improvement partly due to the implementation of these recommendations, and by October 1975, the number of miners estimated to have an annual exposure above the recommended limit had fallen to about 30% of those included in the survey.

Residential radon daughter monitor based on alpha spectroscopy

International Nuclear Information System (INIS)

Nazaroff, W.W.

1980-05-01

The radioactive daughters of radon-222 pose a serious indoor air quality problem in some circumstances. A technique for measuring the concentrations of these radioisotopes in air is presented. The method involves drawing air through a filter; then, for two time intervals after sampling, counting the alpha decays from polonium-218 and polonium-214 on the filter. The time intervals are optimized to yield the maximum resolution between the individual daughter concentrations. For a total measurement time of 50 minutes, individual daughter concentrations of 1.0 nanocuries per cubic meter are measured with an uncertainty of 20%. A prototype of a field monitor based on this technique is described, as is a field test in which the prototype was used to measure radon daughter concentrations as a function of ventilation conditions in an energy-efficient house

Radon daughters and work at display devices

Falk, R.; Nyblom, L.

1986-01-01

It has been shown that ions and electrically charged particles in the air can be transported in the electrostatic field between a face and a display device to either the face or the screen. Radon daughters can occur as ions, or sitting on charged particles. This prestudy shows that radon daughters were manifold concentrated on the face of a doll placed in front of a display device, or in a electrostatic field of the kind typical for displaying devices. The radiation dose, in the skin from the radon daughters in an ordinary office environment plus the addition caused by work at a display device, is not strong enough to cause skin damages alone.

Rh doped Ni and Co catalysts, Rh-M/CeO{sub 2}(20 wt %)-Al{sub 2}O{sub 3} (0.2 wt % of Rh; M = Ni or Co, 20 wt %) were synthesized to produce hydrogen via autothermal reforming (ATR) of commercial gasoline at 700 .deg. C under the conditions of a S/C ratio of 2.0, an O/C ratio of 0.84, and a gas hourly space velocity (GHSV) of 20,000 h{sup -1}. The Rh-Ni/CeO{sub 2}(20 wt %)-Al{sub 2}O{sub 3} catalyst (1) exhibited excellent activities, with H{sub 2} and (H{sub 2}+CO) yields of 2.04 and 2.58 mol/mol C, respectively. In addition, this catalyst proved to be highly stable over 100 h without catalyst deactivation, as evidenced by energy dispersive spectroscopy (EDX) and elemental analyses. Compared to 1, Rh-Co/CeO{sub 2}(20 wt %)-Al{sub 2}O{sub 3} catalyst (2) exhibited relatively low stability, and its activity decreased after 57 h. In line with this observation, elemental analyses confirmed that nearly no carbon species were formed at 1 while carbon deposits (10 wt %) were found at 2 following the reaction, which suggests that carbon coking is the main process for catalyst deactivation.

G antigen of Rh blood group system is present either along with D and/or C positive red cells. Hence, [serologically anti-G presents with the similar picture as that of multiple antibodies (anti-D + anti-C). Differentiating them is important as anti-D + anti-C causes severe hemolytic disease of the fetus and newborn than anti-G. In pregnancies with anti-G alone, alloimmunization due to D antigen could be prevented by prophylactic administration of RhIg. Differentiating between anti-D + C from anti-G in alloimmunized pregnant mothers becomes essential. Sera from antenatal mothers, whose antibody identification by 11-cell panel gave a pattern for anti-D and anti-C were selected. Extended phenotyping for Rh system was performed for these antenatal cases. Differential adsorption and elution testing using R 2 R 2 cells initially and r'r cells subsequently were performed to distinguish anit-G from anti-D + anti-C. Antibody titers of these antibodies were determined and their clinical outcome in the newborn was followed. A pattern suggestive of anti D and anti C on antibody identification were observed in six antenatal cases. On further workup 50 % of them confirmed to have anti G. Antibody titers of anti-G and anti-C were lower than that of Anti-D. All newborns were sensitized in vivo and the antibody specificity in them were confirmed with elution studies. The mothers who had only anti-G were subsequently administered with an appropriate dose of RhIg.Differential adsorption and elution studies help in identifying anti-G and distinguishing it from anti-D plus anti-C, thus helping in better patient management.

Measured objectively, under a quarter of adults and fewer than half of preschool children meet the criteria set in the aerobic physical activity recommendations of the Centers for Disease Control and Prevention. Moreover, adults reportedly are sedentary (seated or lying down) for most of their waking hours. Importantly, greater amounts of sedentary time on parents' part are associated with an increased risk of more sedentary time among their children. A randomized controlled trial targeting mother-child pairs has been designed, to examine whether a movement-to-music video program may be effective in reducing sedentary time and increasing physical activity in the home environment. Mother-child pairs (child age of 4-7 years) will be recruited from among NELLI lifestyle-modification study five-year follow-up cohort participants, encompassing 14 municipalities in Pirkanmaa region, Finland. Accelerometer and exercise diary data are to be collected for intervention and control groups at the first, second and eighth week after the baseline measurements. Background factors, physical activity, screen time, motivation to exercise, and self-reported height and weight, along with quality of life, will be assessed via questionnaires. After the baseline and first week measurements, the participants of the intervention group will receive a movement-to-music video program designed to reduce sedentary time and increase physical activity. Intervention group mother-child pairs will be instructed to exercise every other day while watching the video program over the next seven weeks. Information on experiences of the use of the movement-to-music video program will be collected 8 weeks after baseline. Effects of the intervention will be analyzed in line with the intention-to-treat principle through comparison of the changes in the main outcomes between intervention and control group participants. The study has received ethics approval from the Pirkanmaa Ethics Committee in Human

2010-01-01

Full Text Available In this study we examine the impact of family socioeconomic status (SES, of social support as perceived by mothers, and of their three-month-olds child's sex, on mother-infant and father-infant interaction. A total of 58 mothers and 52 fathers were observed interacting with their infants. Univariate Analysis of Variance (ANOVA revealed several significant differences, particularly regarding maternal behaviors. Mothers from the highest SES level both talked to and interpreted their infants' behavior more than did lowest SES mothers. Social support perceived as unsatisfactory was associated with a greater amount of touch and stimulation during mother-infant interaction and also more infant vocalization. Mothers and fathers tended to talk more to their same-sex infants, and fathers tended to kiss and caress their sons more than they did their daughters. These results suggest particularities in the mother-infant and fatherinfant interaction when the infant was three months old.

Concerns about psychological distress are often used to justify treatment of girls with precocious puberty, but there is little evidence to support these concerns. The extent to which psychological problems are associated with central precocious puberty (CPP) compared with other forms of early puberty in girls has likewise not been established. Girls presenting with untreated CPP, premature adrenarche (PA) or early normal puberty (ENP) were recruited from our pediatric endocrine clinic along with their mothers. Child psychological adjustment was assessed by child self-report and parent report. Parent self-reported personality, anxiety, and depression were also assessed. Differences between groups were explored using one-way ANOVA and Dunnett's T3 test. Sixty-two subjects (aged 7.5 ± 1.4 years, range 4.8-10.5) were enrolled, of whom 19 had CPP, 22 had PA, and 21 had ENP. Girls with ENP were significantly older (8.9 ± .9 years) than girls with CPP (6.9 ± 1.1 years, p psychological adjustment. However, mothers of girls with PA scored significantly higher than mothers of girls with ENP on one measure of depression (p = .04) and stress (p = .01). While mothers of girls with PA report increased psychological distress on some measures, no differences in psychological adjustment were found at baseline amongst the girls themselves. Whether these results will change as puberty progresses in the PA and ENP groups or with treatment of CPP is unknown. Long-term prospective studies are needed in order to further investigate psychological correlates of early puberty in girls.

Thin film thermocouples (TFTCs) can provide more precise in situ temperature measurement for aerospace propulsion systems without disturbance of gas flow and surface temperature distribution of the hot components. ITO/PtRh:PtRh TFTC with multilayer structure was deposited on alumina ceramic substrate by magnetron sputtering. After annealing, the TFTC was statically calibrated for multiple cycles with temperature up to 1000 °C. The TFTC with excellent stability and repeatability was realized for the negligible variation of EMF in different calibration cycles. It is believed that owing to oxygen diffusion barriers by the oxidation of top PtRh layer and Schottky barriers formed at the grain boundaries of ITO, the variation of the carrier concentration of ITO film is minimized. Meanwhile, the life time of TFTC is more than 30 h in harsh environment. This makes ITO/PtRh:PtRh TFTC a promising candidate for precise surface temperature measurement of hot components of aeroengines.

The potential role of mother-in-law in prevention of mother-to-child transmission of HIV: a mixed methods study from the Kilimanjaro region, northern Tanzania

Full Text Available Abstract Background In the Kilimanjaro region the mother-in-law has traditionally had an important role in matters related to reproduction and childcare. The aim of this study was to explore the role of the mothers-in-law in prevention of mother-to-child transmission (PMTCT service utilization and adherence to infant feeding guidelines. Methods The study was conducted during 2007-2008 in rural and urban areas of Moshi district in the Kilimanjaro region of Tanzania. Mixed methods were used and included focus group discussions with mothers-in-law, mothers and fathers; in-depth interviews with mothers-in-law, mothers, fathers and HIV-infected mothers, and a survey of 446 mothers bringing their four-week-old infants for immunisation at five reproductive and child health clinics. Results The study demonstrated that the mother-in-law saw herself as responsible for family health issues in general and child care in particular. However she received limited trust, and couples, in particular couples living in urban areas, tended to exclude her from decisions related to childbearing and infant feeding. Mothers-in-law expected their daughters-in-law to breastfeed in a customary manner and were generally negative towards the infant feeding methods recommended for HIV-infected mothers; exclusive replacement feeding and exclusive breastfeeding. Conclusions Decreasing influence of the mother-in-law and increasing prominence of the conjugal couples in issues related to reproduction and child care, reinforce the importance of continued efforts to include male partners in the PMTCT programme. The potential for involving mothers-in-law in the infant feeding component, where she still has influence in some areas, should be further explored.

Comparison of two methods for investigating indoor radon daughters

International Nuclear Information System (INIS)

Vanmarcke, H.; Raes, F.

1988-01-01

The dynamics of radon daughters in realistic indoor environments has been investigated experimentally at the Universities of Gottingen and Gent. Both studies yielded the important result that the fraction of unattached radon daughters is higher than is assumed in earlier studies. Reineking-Porstendorfer and Vanmarcke-Raes adopted quite different methodologies to determine the unattached fraction. In this paper the methodologies are compared by means of joint measurements performed in a house with elevated radon concentrations. The results for the attachment rate, the deposition rate of the unattached daughters and the unattached fraction differ significantly, while the results for the deposition rate of the attached daughters and the equilibrium factor broadly agree.

Origin of room temperature ferromagnetic moment in Rh-rich [Rh/Fe] multilayer thin films

Kande, Dhishan; Laughlin, David; Zhu Jiangang

2010-01-01

B2 ordered FeRh thin films switch from antiferromagnetic (AFM) to ferromagnetic (FM) state on heating above 350 K and switch back on cooling, with a hysteresis. This property makes FeRh a very attractive choice as a write-assist layer material for low temperature heat assisted magnetic recording (HAMR) media. Studies have shown that as we decrease the thickness of the FeRh films, the B2 phase is no longer AFM even below 350 K and there is a thickness dependant FM stabilization of the B2 phase. It was also proved that slightly Rh-richer compositions (>50 at. % Rh) were more preferable to stabilize the AFM phase. The current study focuses on growing highly ordered FeRh films by alternate layer rf sputtering of thin layers of iron and rhodium onto a heated substrate. It has been shown that films with rhodium content beyond 55 at. % contain a disordered bcc FM phase which gives rise to residual moment at room temperature even for thicker films.

The electronic structure of the Rh-based CuRh0.9Mg0.1O2 oxide thermoelectric compound has been studied with a multitechnique approach consisting of photoemission, x-ray absorption, and x-ray emission spectroscopies. The data indicate that the region of the valence band in the proximity of the Fermi level is dominated by Rh-derived states. These findings outline the importance of the electronic structure of the Rh ions for the large thermoelectric power in CuRh0.9Mg0.1O2 at high temperature.

Spin Correlations of Lambda anti-Lambda Pairs as a Probe of Quark-Antiquark Pair Production

CERN Document Server

Ellis, John

2012-01-01

The polarizations of Lambda and anti-Lambda are thought to retain memories of the spins of their parent s quarks and antiquarks, and are readily measurable via the angular distributions of their daughter protons and antiprotons. Correlations between the spins of Lambda and anti-Lambda produced at low relative momenta may therefore be used to probe the spin states of s anti-s pairs produced during hadronization. We consider the possibilities that they are produced in a 3P_0 state, as might result from fluctuations in the magnitude of , a 1S_0 state, as might result from chiral fluctuations, or a 3S_1 or other spin state, as might result from production by a quark-antiquark or gluon pair. We provide templates for the p anti-p angular correlations that would be expected in each of these cases, and discuss how they might be used to distinguish s anti-s production mechanisms in pp and heavy-ion collisions.

GnRH agonist versus GnRH antagonist in in vitro fertilization and embryo transfer (IVF/ET

2012-04-01

Full Text Available Abstract Several protocols are actually available for in Vitro Fertilization and Embryo Transfer. The review summarizes the main differences and the clinic characteristics of the protocols in use with GnRH agonists and GnRH antagonists by emphasizing the major outcomes and hormonal changes associated with each protocol. The majority of randomized clinical trials clearly shows that in “in Vitro” Fertilization and Embryo Transfer, the combination of exogenous Gonadotropin plus a Gonadotropin Releasing Hormone (GnRH agonist, which is able to suppress pituitary FSH and LH secretion, is associated with increased pregnancy rate as compared with the use of gonadotropins without a GnRH agonist. Protocols with GnRH antagonists are effective in preventing a premature rise of LH and induce a shorter and more cost-effective ovarian stimulation compared to the long agonist protocol. However, a different synchronization of follicular recruitment and growth occurs with GnRH agonists than with GnRH antagonists. Future developments have to be focused on timing of the administration of GnRH antagonists, by giving a great attention to new strategies of stimulation in patients in which radio-chemotherapy cycles are needed.

Relating to corrosion of RH submerged nozzle, resistance against iron oxide of monolithic refractories was examined. Corrosion and seepage of refractories were measured by rotating corrosion, refractories include alumina-spinel castable, which is applied to RH under tank, and alumina-magnesia castable, which is generally used for RH, submerged nozzle. Alumina-spinel castable is superior in resistance against iron oxide than alumina-magnesia castable, and the resistance decreased with increase of stainless fiber addition to castable. Alumina-spinel castable without stainless fiber was suitable for bottom end of the dipping pipe. (NEDO)

Cervical cancer which is one of the most preventable cancers is an important public health problem worldwide, and especially in developing countries. The aim of this study was to determine knowledge and attitudes about the HPV vaccination of mothers with 0- to 18-year old children. Written approval was taken from the local authorities. The study subjects consisted of 799 mothers who agreed to participate. The data were collected via a "Personal Information Form" which included 30 questions that were prepared by the researchers themselves in line with the literature. The data were collected by face to face interviews with the mothers. Analyses were performed using commercial software. The mean age of the mothers who participated in the study was 32.0 ± 6.52, and 88.1% reported no information about HPV, and 83.5% no information about HPV vaccination. Only 0.7% of the mothers had daughters who had HPV vaccination, and 44.3% of the mothers who had sons were found out to be indecisive about having HPV vaccination. There was a significant corelation between the educational status of the mothers and their knowledge about HPV vaccination (p0.05). This study suggested that mothers had very little information on HPV and HPV vaccination. Knowledge of the disease and its vaccination is an essential factor for the success of the vaccination program. It is of great importance that mothers are trained in this subject by health professionals.

It has been demonstrated that compared to low-risk subjects, high-risk subjects for depression have structural and functional alterations in their brain scans even before the disease onset. However, it is not known if these alterations are related to vulnerability to depression or epiphenomena. One way to resolve this ambiguity is to detect the structural alterations in the high-risk subjects and determine if the same alterations are present in the probands. In this study, we recruited 24 women with the diagnosis of Major Depressive Disorder (MDD) with recurrent episodes and their healthy daughters (the high-risk for familial depression group; HRFD). We compared structural brain scans of the patients and HRFG group with those of 24 age-matched healthy mothers and their healthy daughters at similar ages to the HRFD group; respectively. Both cortical gray matter (GM) volume and thickness analyses revealed that HRFD daughters and their MDD mothers had similar GM differences in two regions: the right temporoparietal region and the dorsomedial prefrontal cortex. These results suggested that the observed alterations may be related to trait clinical and neurophysiological characteristics of MDD and may present before the onset of illness.

Mothers adjust offspring sex to match the quality of the rearing environment.

Pryke, Sarah R; Rollins, Lee A

2012-10-07

Theory predicts that mothers should adjust offspring sex ratios when the expected fitness gains or rearing costs differ between sons and daughters. Recent empirical work has linked biased offspring sex ratios to environmental quality via changes in relative maternal condition. It is unclear, however, whether females can manipulate offspring sex ratios in response to environmental quality alone (i.e. independent of maternal condition). We used a balanced within-female experimental design (i.e. females bred on both low- and high-quality diets) to show that female parrot finches (Erythrura trichroa) manipulate primary offspring sex ratios to the quality of the rearing environment, and not to their own body condition and health. Individual females produced an unbiased sex ratio on high-quality diets, but over-produced sons in poor dietary conditions, even though they maintained similar condition between diet treatments. Despite the lack of sexual size dimorphism, such sex ratio adjustment is in line with predictions from sex allocation theory because nutritionally stressed foster sons were healthier, grew faster and were more likely to survive than daughters. These findings suggest that mothers may adaptively adjust offspring sex ratios to optimally match their offspring to the expected quality of the rearing environment.

The GnRH receptor and the response of gonadotrope cells to GnRH pulse frequency code. A story of an atypical adaptation of cell function relying on a lack of receptor homologous desensitization.

Directory of Open Access Journals (Sweden)

Christian Bleux

2010-01-01

Full Text Available Brain control of the reproductive system is mediated through hypothalamic gonadotropin-releasing hormone (GnRH which activates specific receptors (GnRHR present at the surface of the pituitary gonadotropes to trigger secretion of the two gonadotropins LH and FSH. A unique feature of this system is the high dependence on the secretion mode of GnRH, which is basically pulsatile but undergoes considerable fluctuations in pulse frequency pattern in response to endogenous or external factors. How the physiological fluctuations of GnRH secretion that orchestrate normal reproduction are decoded by the gonadotrope cell machinery to ultimately control gonadotropin release and/or subunit gene transcription has been the subject of intensive studies during the past decades. Surprisingly, the mammalian GnRHR is unique among G protein-coupled receptor family as it lacks the carboxy-terminal tail usually involved in classical endocytotic process. Accordingly, it does not desensitize properly and internalizes very poorly. Both this atypical intrinsic property and post-receptor events may thus contribute to decode the GnRH signal. This includes the participation of a network of signaling pathways that differently respond to GnRH together with a growing amount of genes differentially sensitive to pulse frequency. Among these are two pairs of genes, the transcription factors EGR-1 and NAB, and the regulatory factors activin and follistatin, that function as intracellular autoregulatory feedback loops controlling respectively LHbeta and FSHbeta gene expression and hence, LH and FSH synthesis. Pituitary gonadotropes thus represent a unique model of cells functionally adapted to respond to a considerably fluctuating neuroendocrine stimulation, from short individual pulses to sustained GnRH as observed at the proestrus of ovarian cycle. Altogether, the data emphasize the adaptative reciprocal complementarity of hypothalamic GnRH neurones and pituitary gonadotropes to

Randon daughter exposure of the U.K. population

International Nuclear Information System (INIS)

Cliff, K.D.

1980-01-01

The highest dose to the body tissues from natural radioactivity is that to the bronchial epithelium arising predominantly from the short-lived daughters of 222 Rn with a lesser contribution from the daughters of 220 Rn. This paper discusses the estimation of current United Kingdom population exposure to these nuclides. At present the exposure for an average member of the population of the UK is 0.15 WLM y -1 when the winter ventilation rate is 0.8 h -1 . This will increase to 0.58 WLM y -1 if the winter ventilation rate is reduced to 0.2 h -1 . The use of electrostatic precipitators would decrease the measured WL but would not affect the unattached fraction of 222 Rn daughter products, which determines the dose to the epithelium. Other methods of reducing 222 Rn daughter concentrations under investigation include prevention of the ingress of 222 Rn from the subsoil and the coating of construction materials with a radon barrier

Few studies have investigated the individual long-term contributions that mothers and fathers make to their children's schooling. (1) To explore the role of early father involvement in children's later educational attainment independently of the role of early mother involvement and other confounds, (2) to investigate whether gender and family structure moderate the relationship between father's and mother's involvement and child's educational attainment, and (3) to explore whether the impact of father's involvement depends on the level of mother's involvement. The study used longitudinal data from the National Child Development Study. The initial sample were those 7,259 cohort members with valid data on mother involvement at age 7, father involvement at age 7, and school-leaving qualification by age 20. Of those, 3,303 were included in the final analysis. The measures were control variables, structural factors (family structure, sibship size and residential mobility), child factors (emotional/behavioural problems, cognitive ability and academic motivation), and father's and mother's involvement. Father involvement and mother involvement at age 7 independently predicted educational attainment by age 20. The association between parents' involvement and educational attainment was not stronger for sons than for daughters. Father involvement was not more important for educational attainment when mother involvement was low rather than high. Not growing up in intact two-parent family did not weaken the association between father's or mother's involvement and educational outcomes. Early father involvement can be another protective factor in counteracting risk conditions that might lead to later low attainment levels.

RhD Specific Antibodies Are Not Detectable in HLA-DRB11501* Mice Challenged with Human RhD Positive Erythrocytes

Full Text Available The ability to study the immune response to the RhD antigen in the prevention of hemolytic disease of the fetus and newborn has been hampered by the lack of a mouse model of RhD immunization. However, the ability of transgenic mice expressing human HLA DRB11501* to respond to immunization with purified RhD has allowed this question to be revisited. In this work we aimed at inducing anti-RhD antibodies by administering human RhD+ RBCs to mice transgenic for the human HLA DRB11501* as well as to several standard inbred and outbred laboratory strains including C57BL/6, DBA1/J, CFW(SW, CD1(ICR, and NSA(CF-1. DRB11501* mice were additionally immunized with putative extracellular immunogenic RhD peptides. DRB11501* mice immunized with RhD+ erythrocytes developed an erythrocyte-reactive antibody response. Antibodies specific for RhD could not however be detected by flow cytometry. Despite this, DRB11501* mice were capable of recognizing immunogenic sequences of Rh as injection with Rh peptides induced antibodies reactive with RhD sequences, consistent with the presence of B cell repertoires capable of recognizing RhD. We conclude that while HLA DRB11501* transgenic mice may have the capability of responding to immunogenic sequences within RhD, an immune response to human RBC expressing RhD is not directly observed.

2015-01-01

This is a two-study paper that developed a measure to assess parenting practices related to children's physical activity and explored maternal predictors of such parenting practices. Study 1: A self-report measure of parents' activity-related practices (the Parenting Related to Activity Measure) was developed, and a principal component analysis was carried out using data from 233 mothers of 4.5- to 9-year-old children. The results supported a six-factor model and yielded the following subscales: Responsibility/monitoring; Activity regulation; Control of active behaviours; Overweight concern; Rewarding parenting; and Pressure to exercise. Study 2: Mothers (N = 170) completed the Parenting Related to Activity Measure, alongside measures of eating psychopathology and compulsive exercise, to identify predictors of activity-related parenting practices. Mothers' eating psychopathology and exercise beliefs predicted activity parenting practices with their sons and daughters, but different predictors were seen for mothers of daughters versus sons. Mothers' eating and exercise attitudes are important predictors of their activity-related parenting practices, particularly with girls. Identifying early interactions around activity/exercise could be important in preventing the development of problematic beliefs about exercise, which are often a key symptom of eating disorders.

We present {sup 103}Rh NMR studies for the superconductor Rh{sub 17}S{sub 15} (T{sub c} 5.4 K). We have identified the observed NMR lines corresponding to four different Rh sites in the cubic unit cell and deduced the temperature (T) dependence of the Knight shift components in Rh 24m site whose point symmetry is not axial. The isotropic part of the Knight shift K decreases with T in the normal state, indicating the negative hyperfine coupling and the enhancement of the spin susceptibility at lower T. The sudden change of K below T{sub c} is an indication of the spin-singlet Cooper paring.

This study analyzes the relationships between maternal risk factors present at the time of daughters' births-namely, young mother, high parity, and short preceding birth interval-and their subsequent adult developmental, reproductive, and socioeconomic outcomes. Pseudo-cohorts are constructed using female respondent data from 189 cross-sectional rounds of Demographic and Health Surveys conducted in 50 developing countries between 1986 and 2013. Generalized linear models are estimated to test the relationships and calculate cohort-level outcome proportions with the systematic elimination of the three maternal risk factors. The simulation exercise for the full sample of 2,546 pseudo-cohorts shows that the combined elimination of risk exposures is associated with lower mean proportions of adult daughters experiencing child mortality, having a small infant at birth, and having a low body mass index. Among sub-Saharan African cohorts, the estimated changes are larger, particularly for years of schooling. The pseudo-cohort approach can enable longitudinal testing of life course hypotheses using large-scale, standardized, repeated cross-sectional data and with considerable resource efficiency.

The uncertainties in determining the absolute values of the Rh-103(n, n') Rh-103m reaction rate (which is widely used as a neutron damage flux monitor) have been reduced to approximately +-5%. This has been achieved with the use of a calibrated source of Pd-103-Rh-103m activity supplied by the IAEA. Agreement to within 3% between measured and calculated values of the reaction rate (normalised to the U-238 fission rate) has been achieved. (author)

Characterization of Rh films on Ta(110)

The surface and electronic structure of Rh films on Ta(110) up to several monolayers thick on Ta(110) are characterized by photoemission, Auger emission, low energy electron diffraction and low energy ion scattering. From the variation of the Rh Auger peak-to-peak intensity as a function of evaporation time, Rh/Ta(110) appears to grow in the Stranski-Krastanov mode at room temperature. However, the LEIS data show that the Rh adatoms begin to cluster on Ta(110) before growth of the monolayer is completed. Diffuse LEED scattering suggests that the Rh films are disordered. Photoemission shows that Rh chemisorption on Ta(110) generates two peaks located at 1.2 and 2. 5 eV binding energy during the initial phase of thin film growth (0 3.7 ML). Photoemission data for CO covered surfaces show that CO dissociates on the Rh/Ta(110) surface for Rh coverages less than 2.5 ML and also show that the Rh clusters develop at least one site capable of molecular CO adsorption above 0.3 ML Rh coverage. 38 refs., 5 figs

To examine the association between ABO and RhD blood groups and gestational hypertensive disorders in a large population-based cohort. Cohort study. Risks of gestational hypertensive disorders, pre-eclampsia, and severe pre-eclampsia, estimated by odds ratios for maternal ABO blood group and RhD status. National health registers of Sweden. All singleton deliveries in Sweden born to first-time mothers during the period 1987-2002 [total n = 641 926; any gestational hypertensive disorders, n = 39 011 (6.1%); pre-eclampsia cases, n = 29 337 (4.6%); severe pre-eclampsia cases, n = 8477 (1.3%)]. Using blood group O as a reference, odds ratios of gestational hypertensive disorders, pre-eclampsia, and severe pre-eclampsia were obtained from logistic regression models adjusted for potential confounding factors. Gestational hypertensive disorders, pre-eclampsia, and severe pre-eclampsia. Compared with blood group O, all non-O blood groups had modest but statistically significantly higher odds of pre-eclampsia. Blood group AB had the highest risk for pre-eclampsia (OR = 1.10, 95% CI 1.04-1.16) and severe pre-eclampsia (OR = 1.18, 95% CI 1.07-1.30). RhD-positive mothers had a small increased risk for pre-eclampsia (OR = 1.07, 95% CI 1.03-1.10). In the largest study on this topic to date, women with AB blood group have the highest risks of gestational hypertensive disorders, pre-eclampsia, and severe pre-eclampsia, whereas women with O blood group have the lowest risks of developing these disorders. Although the magnitude of increased risk is small, this finding may help improve our understanding of the etiology of pre-eclampsia. © 2012 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2012 RCOG.

1980-01-01

A study was carried out to determine if lung cancer and general mortality rates in 13 Canadian cities were significantly correlated with average indoor radon daughter concentrations. The radon daughter measurements were obtained from a study of 10,000 homes chosen in a statistically valid grab sample basis. Cancer deaths by year of death, sex, age, and cause were retrieved for each of the cities for the period 1957-1976. Age specific and age standardized mortality rates were calculated. The results showed no evidence of any substantial association between general or lung cancer mortality rates and indoor radon daughter concentrations. The limitations of this study and the feasibility of a common international program of epidemiology of radon daughter exposure are discussed. A proposal is made for the use of case control studies of lung cancer to assess the relative importance of smoking, occupational and domestic exposure to radon daughters

The surface and electronic structure of Rh films on Ta(110) up to several monolayers thick on Ta(110) are characterized by photoemission, Auger emission, low-energy electron diffraction (LEED) and low-energy ion scattering (LEIS). From the variation of the Rh Auger peak-to-peak intensity as a function of evaporation time, Rh appears to grow in the Stranski--Krastanov mode at room temperature. However, the LEIS data show that the Rh adatoms begin to cluster on Ta(110) before growth of the monolayer is completed. Diffuse LEED scattering suggests that the Rh films are disordered. Photoemission shows that Rh chemisorption on Ta(110) generates two peaks located at -1.5 and -2.5 eV binding energy during the initial phase of thin-film growth (0 3.7 ML). CO dissociates on the Rh/Ta(110) surface for Rh coverages<2.5 ML and the surface develops a site capable of molecular CO adsorption above 0.3-ML Rh coverage

Efficient measurement of radon daughters

International Nuclear Information System (INIS)

Rolle, R.

1992-01-01

In environmental control there is an increasing need for efficient measurement of radon and thoron daughters in air. Measuring instruments should be rugged and portable for field use, while also permitting unattended operation for several days. Simple operating procedures should permit evaluation of rapidly changing concentrations over extended periods. These requirements demand careful balance in the design of hardware and measuring procedures. The design principles for a continuous flow-through spectrometer, that has been developed for precision sequential measurement of radon and thoron daughters, are described. Because of the high precision of measurement, this type of instrument should find application in environments from technologically enhanced natural radiation to the very lowest natural background situations.

A review, with nearly 100 references, of the biological effects of radon and radon daughters is presented. Calculations of the relative dose from daughter products, as well as of the variation in dose with such things as unattached fraction, particle size, age and breathing rate are discussed. Estimates of annual risk of lung cancer in miners after inhalation of thoron daughters are given, and compared with hazards of employment in various US industries. The implications of these epidemiological studies for future regulations are discussed

Exposure of the gonadotrope cells to gonadotropin-releasing hormone (GnRH) reduces their responsiveness to a new GnRH stimulation (homologous desensitization). The time frame as well as the mechanisms underlying this phenomenon are yet unclear. We studied in a gonadotrope cell line (alphaT3-1) the effects of short as well as long term GnRH pretreatments on the GnRH-induced phospholipases-C (PLC), -A2 (PLA2) and -D (PLD) activities, by measuring the production of IP3, total inositol phosphates (IPs), arachidonic acid (AA) and phosphatidylethanol (PEt) respectively. We demonstrated that although rapid desensitization of GnRH-induced IP3 formation did not occur in these cells, persistent stimulation of cells with GnRH or its analogue resulted in a time-dependent attenuation of GnRH-elicited IPs formation. GnRH-induced IPs desensitization was potentiated after direct activation of PKC by the phorbol ester TPA, suggesting the involvement of distinct mechanisms in the uncoupling exerted by either GnRH or TPA on GnRH-stimulated PI hydrolysis. The levels of individual phosphoinositides remained unchanged under any desensitization condition applied. Interestingly, while the GnRH-induced PLA2 activity was rapidly desensitized (2.5 min) after GnRH pretreatments, the neuropeptide-evoked PLD activation was affected at later times, indicating an important time-dependent contribution of these enzymatic activities in the sequential events underlying the GnRH-induced homologous desensitization processes in the gonadotropes. Under GnRH desensitization conditions, TPA was still able to induce PLD activation and to further potentiate the GnRH-evoked PLD activity. AlphaT3-1 cells possess several PKC isoforms which, except PKCzeta, were differentially down-regulated by TPA (PKCalpha, betaII, delta, epsilon, eta) or GnRH (PKCbetaII, delta, epsilon, eta). In spite of the presence of PKC inhibitors or down-regulation of PKC isoforms by TPA, the desensitizing effect of the neuropeptide on

Daughter preference in Japan: A reflection on gender role attitudes?

Full Text Available BACKGROUND Unlike other East Asian nations where preference for sons over daughters still prevails, gender preference for children in Japan has progressively shifted from son preference to a noticeable daughter preference over the past few decades. This emergence of daughter preference is surprising given that gender relations are more traditional in Japan than in other advanced countries. OBJECTIVE I focus on the extent to which individuals' gender preferences are shaped by their gender role attitudes and evaluate whether daughter preference is a reflection of convergence or a persistent divergence in gender roles in Japan. METHODS I use data from the Single Persons subset of the 11th Japanese National Fertility Survey conducted by the National Institute of Population and Social Security Research in 1997. Using multinomial logistic regression, I estimate the relationship between Japanese singles' gender role attitudes and their type of gender preference for children. RESULTS Findings suggest that the effect of gender role attitudes on one's child gender preference differs for men and women. Overall, while daughter preference is associated with nontraditional gender role attitudes for men, daughter preference is associated with traditional attitudes for women. CONCLUSIONS Traditionalism is still driving gender preference, though in a different way for men and women. Emerging daughter preference may not simply be a reflection of improvements in women's status, but in fact it is likely that persistent divergence in gender roles remain in Japan.

By the continuous measurement of the radon daughters concentration in the rain and snow water and atmosphere and the data analysis, the following results were obtained. The radon daughters concentration was almost constant in the rain and snow water in spite of the length during weather without precipitation. It has not tendency to show the high concentration of radon daughters in precipitation and snow during beginning of them. When the precipitation intensity is constant, it`s concentration does not change during precipitation and snowfall. The concentration does not depend on the amount of precipitation, but on the precipitation intensity. We did not observe a correlation between the radon daughters concentration in the rain and snow water and that in the surface air. The atmospheric concentration was decreased by precipitation and snowfall, but that of rain and snow water did not decrease. The above results seems to show that the contribution of washout under the cloud to radon daughters in rain and snow water is small and that of rainout in the cloud is large. This result is agreement with the Jacob`s experimental results. (S.Y.)

First and second generation Mexican-origin adolescents in the U.S. face social and economic disadvantage and sexual health disparities. Although fathers can support child and adolescent development, the literature has portrayed Mexican-origin immigrant fathers as emotionally distant and sexist. This study aims to treat migration as a social determinant of health to examine father-daughter relationships and adolescent sexual health in Mexican-origin immigrant families. Integrating qualitative data from life history interviews with 21 Mexican-origin young women in immigrant families with quantitative data on first and second generation Mexican-origin young women in the National Longitudinal Study of Adolescent to Adult Health, this study describes father-daughter relationships, examines the association between father-daughter relationships and daughters' early sexual initiation, and considers the impact of migration on the father-daughter relationship and sexual health among Mexican-origin young women. Qualitative data identify four types of father-daughter relationships: 'good,' hostile, distant, and conflicted. Supporting the qualitative patterns, quantitative data find that positive or 'good' father-daughter relationship quality is significantly associated with reduced risk of early sexual initiation. Importantly, father-daughter separation across borders and economic inequality facing immigrant families is associated with hostile or distant father-daughter relationship quality and increased risk of early sexual initiation. Reports of good father-daughter relationships are common and may protect against early sexual initiation in Mexican-origin immigrant families. Policies that keep families together and reduce economic inequality among immigrants may also reduce sexual health disparities among immigrant adolescents.

To assess the prevalence of cardiovascular events in an older population of women with polycystic ovary syndrome (PCOS). We took advantage of the high heritability of PCOS and determined the probable PCOS status of mothers of women with PCOS. The prevalence of cardiovascular events was then determined in these mothers with and without PCOS. In a single endocrine clinic, 308 women with PCOS were interviewed about their mothers' medical history, and the mothers themselves were interviewed if available. The interview addressed menstrual history, fertility, clinical signs of hyperandrogenism, age at incident cardiovascular event, and age at death as reported by daughters. Presence of PCOS in the mothers was defined as a history of infertility, irregular menses, or clinical signs of hyperandrogenism. A cardiovascular event was defined as fatal or nonfatal myocardial infarction, any coronary intervention, angina necessitating emergency department visits, or a cerebrovascular event. The mothers were predominantly post-menopausal. Among 182 interviewed (n = 157) or deceased (n = 25) mothers, 59 had probable PCOS. Cardiovascular events were more common (P = .011) among mothers with PCOS (11 of 59 or 18.6%) than among non-PCOS mothers (5 of 123 or 4.1%). After adjustments were made for age and race, probable PCOS was an independent predictor of cardiovascular events (odds ratio, 5.41; 95% confidence interval, 1.78 to 16.40). Cardiovascular events occurred at an early age in mothers of women with PCOS, particularly mothers with probable PCOS themselves. PCOS-affected mothers of women with PCOS have a higher risk for cardiovascular events in comparison with non-PCOS mothers, and cardiovascular events appear to occur at an earlier than expected age in mothers with PCOS.

Dowry calculations: daughter's rights in her parental family.

The practice of dowry in India has become identified as the primary cause of women's oppression. It sets families apart in the fight over dowry payments and results in violence against daughters including infanticide. Daughter's get their share of inheritance at the time of marriage under traditional Hindu law. The Dowry Prohibition Act outlaws this practice. On the other hand, customary law allowed entitlements to women which Victorian norms bypassed, thereby paving the way for the disinheritance of women. The ownership of land was vested exclusively in men, and, as land became scarce and women's labor became devalued, women came to be treated as mere dependents and considered as a liability. With the entrance of men into government service as policemen and bank and postal clerks, their status increased, while women continued working in the peasant economy. Government job holders received the biggest dowries because of their access to economic opportunities. Under the Hindu Succession Act, fathers were allowed to will away property in whosoever's favor, which led to the disinheritance of daughters in favor of sons. Inheritance laws increasingly moved in favor of men and against women. Changing marriage patterns also emerged, as paying exorbitant dowries was perceived as a way of upward social mobility. The wife inherited everything at the expense of daughters, and widows automatically got a pension after the husband. Therefore, the wife's right had a stronger social sanction than the rights of daughters in parental property, especially the right to live in the parental home and take care of old parents, should be the solution to this injustice. Thus, parents would look at daughters in the same light as sons, and the culture of women's devaluation would come to an end.

Abstract Background Despite widespread use of pneumococcal conjugate vaccines (PCVs), Streptococcus pneumoniae (pneumococcus) remains an important cause of pneumonia. Prior to widespread PCV use, we found a high prevalence of nasopharyngeal (NP) colonization with pneumococcus resistant to multiple antibiotic classes among young children in the rural highlands of Peru. We sought to confirm contemporary resistance profiles among young children, their mothers, and animal contacts in the post-PCV era. Methods We enrolled eligible members of Peruvian households whose children had participated in our previous study. Mothers were questioned about antibiotic use for themselves and their children age <3 years. NP samples were collected from children, mothers, and their animal contacts including cows, guinea pigs, and dogs, when available. Samples were cultured for pneumococcus using standard methods and routine disk antibiotic susceptibility testing was performed. Drinking water and milk samples were tested, when available, for the presence of β-lactam and tetracycline residues (IDEXX Β-Tetra testing kit; Westbrook, ME). Results Members of 47 households were enrolled, including 50 children and 47 mothers (3 sibling pairs). The median (IQR) age of children was 1.2 years (0.6-2.2) and number of household members was 5 (4-6). Sixteen of 50 (32%) children and 7/47 (15%) mothers had received antibiotics in the prior 6 months (Fig 1). Pneumococcus was detected in 31/50 (62%) children, 9/47 (19%) mothers, and 1/31 (3%) guinea pigs. Pneumococci were not detected in dogs (n = 29) or cows (n = 7). Resistance to multiple classes of antibiotics, including TMP-SMX, tetracyclines, and β-lactams, was common among children and adults (Fig 2). No antibiotic residues were detected in water (n = 41) or milk (n = 7) samples. Conclusion Pneumococcal colonization was common among young children, less prevalent among adults, and rare among animals. Resistance to macrolides and

Full Text Available Given prior evidence that an affected woman conveys a higher risk of ovarian cancer to her sister than to her mother, we hypothesized that there exists an X-linked variant evidenced by transmission to a woman from her paternal grandmother via her father. We ascertained 3,499 grandmother/granddaughter pairs from the Familial Ovarian Cancer Registry at the Roswell Park Cancer Institute observing 892 informative pairs with 157 affected granddaughters. We performed germline X-chromosome exome sequencing on 186 women with ovarian cancer from the registry. The rate of cancers was 28.4% in paternal grandmother/granddaughter pairs and 13.9% in maternal pairs consistent with an X-linked dominant model (Chi-square test X2 = 0.02, p = 0.89 and inconsistent with an autosomal dominant model (X2 = 20.4, p<0.001. Paternal grandmother cases had an earlier age-of-onset versus maternal cases (hazard ratio HR = 1.59, 95%CI: 1.12-2.25 independent of BRCA1/2 status. Reinforcing the X-linked hypothesis, we observed an association between prostate cancer in men and ovarian cancer in his mother and daughters (odds ratio, OR = 2.34, p = 0.034. Unaffected mothers with affected daughters produced significantly more daughters than sons (ratio = 1.96, p<0.005. We performed exome sequencing in reported BRCA negative cases from the registry. Considering age-of-onset, one missense variant (rs176026 in MAGEC3 reached chromosome-wide significance (Hazard ratio HR = 2.85, 95%CI: 1.75-4.65 advancing the age of onset by 6.7 years. In addition to the well-known contribution of BRCA, we demonstrate that a genetic locus on the X-chromosome contributes to ovarian cancer risk. An X-linked pattern of inheritance has implications for genetic risk stratification. Women with an affected paternal grandmother and sisters of affected women are at increased risk for ovarian cancer. Further work is required to validate this variant and to characterize carrier families.

Overcoming artefact: anticipation in 284 Portuguese kindreds with familial amyloid polyneuropathy (FAP) ATTRV30M.

Early-onset (≤40 years) and later-onset (≥50 years) cases of familial amyloid polyneuropathy (FAP) ATTRV30M are not different entities, often coexisting in the same family, and showing anticipation (earlier age-at-onset (AO) in younger generations, usually associated with more severe phenotype). Historically, anticipation has been ascribed to ascertainment biases. Our aim was to study anticipation in a very large number of FAP kindreds, removing possible biases, and gain further insight into parent-of-origin effects. We analysed 926 parent-offspring pairs (from the Unidade Clínica de Paramiloidose roster, collected in 70 years), both clinically observed and had well-established AO, correcting for intrafamilial correlations. Women had a significantly higher AO, either for daughters (mean: 33.70, SD: 6.84) vs sons (29.43, 6.08); or mothers (39.57, 11.75) vs. fathers (35.62, 11.62). Also, 291 pairs showed marked anticipation (≥10 years); the transmitting parent was the mother in 203 pairs. Mother-son pairs showed larger anticipation (10.43, 9.34), while father-daughter pairs showed only a residual anticipation (1.23, 9.77). Gender of offspring and parents was highly significant (with no interaction). To remove possible biases, we repeated analyses: (1) excluding the proband; (2) removing pairs with simultaneous onset; and (3) excluding offspring born after 1960. Anticipation was found in all subsamples, with the same trend for a parent-of-origin effect. Noteworthy, parents with AO ≤40 years never had offspring with AO ≥50. These findings confirm anticipation as a true biological phenomenon, also in FAP ATTRV30M. Acknowledgment of anticipation may have important clinical implications in genetic counselling of offspring and in follow-up of mutation carriers.

Workshop on dosimetry for radon and radon daughters

Emphasis is placed on the dosimetry for radon and daughters, rather than on monitoring and instrumentation. The objectives of the meeting were to exchange scientific information, to identify problem areas in radon-daughter dosimetry, and to make any observations or recommendations by the participants through issuance of this report. The discussion topics included the history of dosimetry for radon and daughters, human data, aerosols, deposition and movement in the respiratory tract, dose calculations, dose-to-working-level-month (WLM) conversion factors, animal experiments, and the development of regulations and remedial criteria for reducing population exposures to radon daughters. This report contains a summary of Workshop discussions plus individual statements contributed by several of the participants. The outstanding problem areas from the standpoint of dosimetry appear to involve the appropriate lung organ mass to be used (average lung-tissue dose vs. high-level local dose); recognition of the discrete, rather than continuous, structure of the mucus; lack of knowledge about lung clearance; the variability of dose with the degree of disequilibrium and the unattached fraction of radon daughters for a given WLM; and questions about the character of uranium mine atmospheres actually breathed in the older mines from which much of the epidemiological information originates. The development of criteria for taking remedial action to reduce exposures involves additional concerns of basing long-term risk assessment on short-term sampling and applying WLM data for miners to general populations

Clinical evidence reveals the importance of mother-newborn bonding experience for health promoting and maintenance of human life. If the newborn lacks care and affection, she/he may develop an attachment disorder. A predictive scale regarding the risk of mothernewborn relationships is available, which makes possible an early intervention to prevent the development of relational disorders. The aim of this study is to apply the Kimelman measurement scale to determine the relational risk in mother-newborn pairs, as well as the prevalence and the associated biopsychosocial variables. A cross-sectional study with a probabilistic sample of 333 mother-infant pairs in postpartum maternity at Temuco hospital. The Kimelman mother-newborn attachment assessment guide was used. Biopsychosocial variables were obtained from the mothers studied. The association of biopsychosocial variables with relational risk was analyzed using OR and confidence intervals of 95%. The prevalence of high relational risk was 43.8%. The associated biopsychosocial variables included, women with no steady partner, single parent, teenage mothers, unwanted and unplanned pregnancy. Almost half of the mothers were in the high risk group. Early identification of relational risk and its related variables could help in the intervention in this vulnerable group. Copyright © 2015.

Incontinentia pigmenti (IP; Online Mendelian Inheritance in Man catalog #308300) is an X-linked dominant ectodermal disorder caused by mutations of the inhibitor of κ polypeptide gene enchancer in B cells, kinase γ ( IKBKG )/ nuclear factor κB, essential modulator ( NEMO ) gene. Hemizygous IKBKG/NEMO loss-of-function (LoF) mutations are lethal in males, thus patients are female, and the disease is always transmitted from an IP-affected mother to her daughter. We present 2 families with father-to-daughter transmission of IP and provide for the first time molecular evidence that the combination of somatic and germ-line mosaicism for IKBKG/NEMO loss of function mutations in IP males resulted in the transmission of the disease to a female child. We searched for the IKBKG/NEMO mutant allele in blood, urine, skin, and sperm DNA and found that the 2 fathers were somatic and germ-line mosaics for the p.Gln132×mutation or the exon 4-10 deletion of IKBKG/NEMO , respectively. The highest level of IKBKG/NEMO mutant cells was detected in the sperm, which might explain the recurrence of the disease. We therefore recommend careful clinical evaluation in IP male cases and the genetic investigation in sperm DNA to ensure correct genetic counseling and prevent the risk of paternal transmission of IP.

The deposition rates of radon daughters on indoor surfaces have been measured by exposing the window of a proportional counter to the air of a house with high concentrations of radon and its daughters. Deposition velocities for unattached 218 Po (RaA) and 214 Pb (RaB) of approximately 4 mm sec - 1 were obtained by dividing the deposition rates by the concentrations of unattached daughters in the air. These results agree with those obtained by other workers but are dependent on the assumptions made about the fractions of the daughters which are attached to the atmospheric aerosol

The period of hospital stay and the first month after discharge have been found to be the most problematic stages for family caregivers of stroke survivors. It is just at home that patients and caregivers actually understand the whole consequences of the stroke. The adult offspring often have more different needs and concerns than spousal caregivers. However, relatively little attention has been paid to the needs of this particular group of caregivers. Therefore, this qualitative content analysis study aimed to explore the supportive needs and coping behaviors of daughter and daughter in-law caregivers (DILs) of stroke survivors one month after the patient's discharge from the hospital in Shiraz, Southern of Iran. This is a qualitative content analysis study using semi-structured and in-depth interviews with a purposive sampling of seventeen daughter and daughter in-law caregivers. The data revealed seven major themes including information and training, financial support, home health care assistance need, self-care support need, adjusting with the cultural obligation in providing care for a parent in-law, and need for improving quality of hospital care. Also, data from the interview showed that daughter and daughter in-law caregivers mostly used emotional-oriented coping strategies, specially religiosity, to cope with their needs and problems in their care-giving role. The results of this qualitative study revealed that family caregivers have several unmet needs in their care-giving role. By providing individualized information and support, we can prepare these family caregivers to better cope with the home care needs of stroke survivors and regain control over aspects of life.

Full Text Available Objective: To verify the presence of depression, age, level of schooling, occupation, marital status, number of children and nutritional status (maternal and of the child in mothers of overweight and eutrophic children and relate the data to mother/child bonding. Methods: A total of 120 mothers of children aged up to 10 years participated; 30 of them were overweight and 30 were eutrophic (low-income bracket; 30 were overweight and 30 eutrophic (high-income bracket. The control group was composed of eutrophic children paired according to sex, age, level of schooling, and social condition. Data collection was made through interviews. The assessment instruments were: Mother/Child Bonding Assessment Protocol and Beck Depression Inventory. The nutritional classification was defined by calculation of the body mass index, as per the curves of the World Health Organization. For statistics, McNemar, χ2, and Fisher’s exact tests were used. A 5% level of rejection of the null hypothesis was set. Results: There was no significant result between mother/child bonding and the variables studied, or between the presence of depression and level of schooling, marital status, occupation, and maternal nutritional status. Nevertheless, mothers of eutrophic children (high-income bracket showed less depression than mothers of eutrophic children (low-income bracket. Mothers with three or more children displayed more depression than mothers with less than three children. Mothers under 30 years of age showed more depression than mothers aged 30 years or older. Conclusion: There was no significant result between mother/child bonding and the variables studied, but the bond was compromised in all mothers of the sample. There was a significant result regarding the presence of depression.

The uncertainties in determining the absolute values of the Rh-103 (n, n') Rh-103m reaction rate (which is widely used as a neutron damage flux monitor) have been reduced to {approx}{+-}5%. This has been achieved with the use of a calibrated source of Pd-103-Rh-103m activity supplied by the I.A.E.A. Agreement to within 3% between measured and calculated values of the reaction rate (normalised to the U-238 fission rate) has been achieved. (author)

Spin correlations of Λanti Λ pairs as a probe of quark-antiquark pair production

International Nuclear Information System (INIS)

Ellis, John; Hwang, Dae Sung

2012-01-01

The polarizations of Λ and anti Λ are thought to retain memories of the spins of their parent s quarks and anti s antiquarks, and are readily measurable via the angular distributions of their daughter protons and antiprotons. Correlations between the spins of Λ and anti Λ produced at low relative momenta may therefore be used to probe the spin states of s anti s pairs produced during hadronization. We consider the possibilities that they are produced in a 3 P 0 state, as might result from fluctuations in the magnitude of left angle anti ss right angle, a 1 S 0 state, as might result from chiral fluctuations, or a 3 S 1 or other spin state, as might result from production by a quark-antiquark or gluon pair. We provide templates for the p anti p angular correlations that would be expected in each of these cases, and discuss how they might be used to distinguish s anti s production mechanisms in pp and heavy-ion collisions.

Teenage Daughters as a Cause of Divorce

OpenAIRE

Kabátek, Jan; Ribar, David C.

2017-01-01

Evidence from the U.S. that couples with daughters are more likely to divorce than couples with sons has not been found for other Western countries. Using 1995-2015 Dutch marriage registry data, we show that daughters are associated with higher divorce risks, but only when they are 13 to 18 years old. There are no detectable gender differences before or after those ages. These age-specific findings are at odds with son-preference and selection explanations for differences in divorce risks. In...

"I Want Her to Make Correct Decisions on Her Own:" Former Soviet Union Mothers' Beliefs about Autonomy Development.

Komolova, Masha; Lipnitsky, Jane Y

2017-01-01

This qualitative study examined Former Soviet Union (FSU) mothers' explicit and implicit attitudes and parenting practices around adolescents' autonomy development. Interviews were conducted with 10 mothers who had immigrated from the FSU to the US between 10 and 25 years ago, and who had daughters between the ages of 13 and 17 years. Mothers predominantly defined autonomy in terms of adolescents' ability to carry out instrumental tasks, make correct decisions, and financially provide for themselves, but rarely mentioned psychological or emotional independence. Mothers reflected on the various aspects of autonomy emphasized in their country of origin and America, and balancing the two sets of cultural values in their parenting. Although mothers discussed attempts to adopt a less authoritarian approach to parenting than they themselves experienced as children, some mothers' controlling attitudes were revealed through a close analysis of their language. The findings provide important insights into the parenting experiences of FSU immigrant mothers, and the way in which autonomy-related processes may vary cross-culturally. Implications for parenting and clinical practice are also discussed.

Sluiter, M.; Turchi, P.; Fu Zezhong; de Fontaine, D.

1988-01-01

Tight-binding electronic band-structure calculations were combined with a free-energy expression from a statistical mechanical method called the cluster-variation method. The effective pair interactions used in the cluster-variation calculation were evaluated by the generalized perturbation method. Only d orbitals were included and the numbers of d electrons per atom were taken to be three for the pure A element and eight for the pure B. A phase diagram was constructed incorporating, for the first time, both fcc and bcc lattices and their simple-ordered superstructures. The calculated diagram agreed reasonably well with those determined empirically for Ti-Rh or Ti-Ir

Bámaca-Colbert, Mayra Y.; Umaña-Taylor, Adriana J.; Gayles, Jochebed G.

2011-01-01

The current study tested a developmental-contextual model of depressive symptomatology among early and middle adolescent Mexican-origin females and their mothers. The final sample was comprised of 271 dyads. We examined the interrelations among cultural (i.e., acculturation dissonance), developmental (i.e., pubertal development and autonomy expectation discrepancies), and interpersonal (i.e., mother-daughter conflict and maternal supportive parenting) factors in predicting adolescents’ depressive symptoms. For both early and middle adolescents, maternal support was negatively associated with mother-daughter conflict and depressive symptoms. Importantly, mother-daughter autonomy expectation discrepancies were positively associated with mother-daughter conflict, but this association was found only among early adolescents. Further, mother-daughter acculturation dissonance was positively associated with mother-daughter conflict, but only among middle adolescents. Findings call for concurrently examining the interface of developmental, relational, and cultural factors in predicting female adolescents’ depressive symptomatology and the potential differences by developmental stage (e.g., early vs. middle adolescence) PMID:21967564

To estimate the intergenerational association in teenage pregnancy, and whether there is a coupling tendency between a mother and daughter in how their teen pregnancies end, such as an induced abortion (IA) vs. a livebirth. Population-based cohort study. Ontario, Canada. 15,097 mothers and their 16,177 daughters. Generalized estimating equations generated adjusted odds ratios (aOR) of a daughter experiencing a teen pregnancy in relation to the number of teen pregnancies her mother had. Multinomial logistic regression estimated the odds that a teen pregnancy ended with IA among both mother and daughter. All models were adjusted for maternal age and world region of origin, the daughter's socio-demographic characteristics and comorbidities, mother-daughter cohabitation, and neighborhood-level teen pregnancy rate. Teen pregnancy in the daughter, between ages 15-19 years, and also the nature of the daughter's teen pregnancy, categorized as i) no teen pregnancy, ii) at least one teen pregnancy, all exclusively ending with a livebirth, and iii) at least one teen pregnancy, with at least one teen pregnancy ending with an IA. The proportion of daughters having a teen pregnancy among those whose mother had 0, 1, 2, or ≥ 3 teen pregnancies was 16.3%, 24.9%, 33.5% and 36.3%, respectively. The aOR of a daughter having a teen pregnancy was 1.42 (95% CI 1.25-1.61) if her mother had 1, 1.97 (95% CI 1.71-2.26) if she had 2, and 2.17 (95% CI 1.84-2.56) if her mother had ≥ 3 teen pregnancies, relative to none. If a mother had ≥ 1 teen pregnancy ending with IA, then her daughter had an aOR of 2.12 (95% CI 1.76-2.56) for having a teen pregnancy also ending with IA; whereas, if a mother had ≥ 1 teen pregnancy, all ending with a livebirth, then her daughter had an aOR of 1.73 (95% CI 1.46-2.05) for that same outcome. There is a strong intergenerational occurrence of teenage pregnancy between a mother and daughter, including a coupling tendency in how the pregnancy ends. This

THE PSYCHOANALYTIC CONTRIBUTIONS OF MELITTA SCHMIDEBERG KLEIN. MORE THAN MELANIE KLEIN'S REBEL DAUGHTER.

Cassullo, Gabriele

Compared to the impact of the work of Melanie Klein on the history of psychoanalysis, the contributions of her daughter, Melitta Schmideberg, passed almost unnoticed. At present, Schmideberg is solely remembered for having harshly attacked her mother at the start of the Controversial Discussions of the British Psycho-Analytical Society and for having coined the fitting expression "stable instability" in order to describe borderline and asocial personality disorders. However, the author discusses how the early groundbreaking discoveries of Klein with regards to primitive anxieties were the result of the joint work and thinking of Melanie and Melitta. Moreover, he argues that the conflict between the two, along with the subsequent polarization of their views, did not facilitate the development of psychoanalysis, neither did it help the analytic community to recognize the value of Melitta's contributions to psychoanalysis.
