Parent-Child Dynamics and Emerging Adult Religiosity: Attachment, Parental Beliefs, and Faith Support

Parental religiosity has been shown to predict child and adolescent religiosity, but the role of parents in emerging adult religiosity is largely unknown. We explored associations among emerging adult religiosity, perceived parental religiosity, perceived similarity to mother's and to father's religious beliefs, parental faith support, and parental attachment. Participants were 481 alumni of two Christian colleges and completed surveys online. Emerging adult religiosity (measured by Christian orthodoxy and intrinsic religiosity) was high and similar to parents' religiosity. Perceived similarity to parents' religious beliefs, faith support, and attachment to fathers predicted emerging adult religiosity. However, parental religiosity alone was a weak predictor and functioned as a negative suppressor variable when combined with similarity to parents' beliefs and faith support. Findings underscore the importance of parental support and parent-child relationship dynamics more than the level of parental religiosity and point to possibly unique roles for mothers and fathers in emerging adult religiosity.

Proteins encoded in genomic regions associated with immune-mediated disease physically interact and suggest underlying biology

Genome-wide association studies (GWAS) have defined over 150 genomic regions unequivocally containing variation predisposing to immune-mediated disease. Inferring disease biology from these observations, however, hinges on our ability to discover the molecular processes being perturbed by these risk variants. It has previously been observed that different genes harboring causal mutations for the same Mendelian disease often physically interact. We sought to evaluate the degree to which this is true of genes within strongly associated loci in complex disease. Using sets of loci defined in rheumatoid arthritis (RA) and Crohn's disease (CD) GWAS, we build protein-protein interaction (PPI) networks for genes within associated loci and find abundant physical interactions between protein products of associated genes. We apply multiple permutation approaches to show that these networks are more densely connected than chance expectation. To confirm biological relevance, we show that the components of the networks tend to be expressed in similar tissues relevant to the phenotypes in question, suggesting the network indicates common underlying processes perturbed by risk loci. Furthermore, we show that the RA and CD networks have predictive power by demonstrating that proteins in these networks, not encoded in the confirmed list of disease associated loci, are significantly enriched for association to the phenotypes in question in extended GWAS analysis. Finally, we test our method in 3 non-immune traits to assess its applicability to complex traits in general. We find that genes in loci associated to height and lipid levels assemble into significantly connected networks but did not detect excess connectivity among Type 2 Diabetes (T2D) loci beyond chance. Taken together, our results constitute evidence that, for many of the complex diseases studied here, common genetic associations implicate regions encoding proteins that physically interact in a preferential manner, in line with observations in Mendelian disease.

[Fetal programming of cardiovascular disease: new causes and underlying mechanisms]

There exists an association between pathologic events occurring during early life and the development of cardiovascular disease in adulthood. For example, transient perinatal hypoxemia predisposes to exaggerated hypoxic pulmonary hypertension and preeclampsia predisposes the offspring to pulmonary and systemic endothelial dysfunction later in life. The latter finding offers a scientific basis for observations demonstrating an increased risk for premature cardiovascular morbidity in this population. Very recently, we showed that offspring of assisted reproductive technologies also display generalized vascular dysfunction and early arteriosclerosis. Studies in animal models have provided evidence that oxidative stress and/or epigenetic alterations play an important pathophysiological role in the fetal programming of cardiovascular disease.

Influence of Engineering Instructors' Teaching and Learning Beliefs on Pedagogies in Engineering Science Courses

This study explored how academics' beliefs about teaching and learning influenced their teaching in engineering science courses typically taught in the second or third year of 4-year engineering undergraduate degrees. Data were collected via a national survey of 166 U. S. statics instructors and interviews at two different institutions with 17 instructors of engineering science courses such as thermodynamics, circuits and statics. The study identified a number of common beliefs about how to best support student learning of these topics; each is discussed in relation to the literature about student development and learning. Specific recommendations are given for educational developers to encourage use of research-based instructional strategies in these courses.

Personality and Current Political Beliefs | Comparative Study of Polish and Belgian Samples)"

This project had a threefold aim and sought to provide answers to several different questions. Kossowska first focused on the relationship between Openness to Experience and ideological variables such as authoritarianism and conservatism. The main questions here were (1) whether there are differences between the Polish and Belgian samples studied with respect to the relationship between political ideology and Openness to Experience, and (2) whether this relationship applies to all facets of Openness to Experience. The study showed significant negative correlations between Openness and right-wing ideology in both adult samples, and that Fantasy and Actions were the most robust correlates of political ideology. A second problem examined concerned the relationship between ideology and cognitive functioning. The important questions here were about the conceptualisation and measurement of cognitive variables such as rigidity, intolerance of ambiguity, or the need for closure, which determine individuals' attitudes to politics. The results confirmed the significance of the need for closure construct in both samples for understanding the process of formulating and holding political beliefs. The last aspect of the study was the differences in political beliefs between the Polish and Belgian samples in relation to the social, political and economic situation in the two countries. The most important question here was the changes in the political mentality of Poles during the period of system transition. Kossowska expected to find differences between Poles and Belgians with respect to the level of conservatism and authoritarianism, but in fact both samples showed comparable levels of right-wing political beliefs.

[High altitude pulmonary edema. An experiment of nature to study the underlying mechanisms of hypoxic pulmonary hypertension and pulmonary edema in humans]

High altitude constitutes an exciting natural laboratory for medical research. Over the past decade, it has become clear that the results of high-altitude research may have important implications not only for the understanding of diseases in the millions of people living permanently at high altitude, but also for the treatment of hypoxemia-related disease states in patients living at low altitude. High-altitude pulmonary edema (HAPE) is a life-threatening condition occurring in predisposed, but otherwise healthy subjects, and, therefore, allows to study underlying mechanisms of pulmonary edema in humans, in the absence of confounding factors. Over the past decade, evidence has accumulated that HAPE results from the conjunction of two major defects, augmented alveolar fluid flooding resulting from exaggerated hypoxic pulmonary hypertension, and impaired alveolar fluid clearance related to defective respiratory transepithelial sodium transport. Here, after a brief presentation of the clinical features of HAPE, we review this novel concept. We provide experimental evidence for the novel concept that impaired pulmonary endothelial and epithelial nitric oxide synthesis and/or bioavailability may represent the central underlying defect predisposing to exaggerated hypoxic pulmonary vasoconstriction and alveolar fluid flooding. We demonstrate that exaggerated pulmonary hypertension, while possibly a condition sine qua non, may not be sufficient to cause HAPE, and how defective alveolar fluid clearance may represent a second important pathogenic mechanism. Finally, we outline how this insight gained from studies in HAPE may be translated into the management of hypoxemia related disease states in general.
