Suburbs have demographically diversified in terms of race, yet little research has been done on household structures in suburbs. Using the 2011 American Housing Survey and 2009-2013 American Community Survey, this study investigates the distributions of household structures in suburbia and central cities, and the relationship between household structures and residential attainment. The findings of this research include: (1) The distribution of household structures differs between suburbia and central cities...

Effects observed within one generation disregard potential detrimental effects that may appear across generations. Previously we have developed a two generation Daphnia magna reproduction test using the OECD TG 211 protocol with a few amendments, including initiating the second generation with third brood neonates produced from first generation individuals. Here we showed the results of an inter-laboratory calibration exercise among 12 partners that aimed to test the robustness and consistency of a two generation Daphnia magna reproduction test...

In the case of the pests inhabiting metal polluted or fields where the use of pesticides is common, a natural selection of resistant individuals can occur. This may pose serious problems for humans, agriculture, as well as the economies of many countries. In this study, the hypothesis that multigenerational (120 generations) exposure to cadmium of a beet armyworm population could be a selecting factor toward a more efficient DNA protection was verified. The hemocytes of individuals from two culture strains (control and Cd-exposed) were treated with H2O2 (a DNA-damaging agent) or PBS (reference)...

PURPOSE OF REVIEW: Although the importance of optimizing mothers' health prior to conception and during pregnancy is now well accepted, recent data also implicate health and nutritional status of fathers as contributors to chronic disease risk in their progeny. This brief review will highlight recent epidemiological and experimental studies linking paternal overnutrition, undernutrition, and other forms of stress, to metabolic disease in the offspring. RECENT FINDINGS: The past 2 years have brought tremendous insights into the mechanisms by which paternal exposures can contribute to disease susceptibility in the next generation...

BACKGROUND: While black mothers initiate human milk (HM) provision at lower rates than non-black mothers in the United States, some neonatal intensive care units (NICUs) report similar initiation rates regardless of race/ethnicity for mothers of very-low-birth-weight (VLBW) infants. However, racial disparity frequently becomes evident in the proportion of black infants who continue to receive HM feedings at NICU discharge. Since social factors have been associated with differences in HM provision for term infants, we sought to identify differences in social factors associated with HM feeding at discharge based on race/ethnicity...

This study assessed and monitored 40 consecutive reproduction tests - multigenerational (MG) - of continuous exposure to Cd (at 2 reproduction Effect Concentrations (EC): EC10 and EC50) using the standard soil invertebrate Folsomia candida, in total 3.5 years of data were collected. Endpoints included survival, reproduction, size and metallothionein (MTc) gene expression. Further, to investigate adaptation to the toxicant, additional standard toxicity experiments were performed with the MG organisms of F6, F10, F26, F34 and F40 generations of exposure...

INTRODUCTION: Distal hereditary motor neuropathy (dHMN) causes distal-predominant weakness without prominent sensory loss. Myosin heavy chain disorders most commonly result in distal myopathy and cardiomyopathy with or without hearing loss, but a complex phenotype with dHMN, myopathy, hoarseness, and hearing loss was reported in a Korean family with a c.2822G>T mutation in MYH14. OBJECTIVE: To report phenotypic features in a North American family with the c.2822G>T in MYH14...

One-quarter of the Head Start population has a mother who participated in the program as a child. This study uses experimental Head Start Impact Study (HSIS) data on 3- and 4-year-olds (N = 2,849) to describe multigenerational Head Start families and their program experiences. In sharp contrast to full-sample HSIS findings, Head Start has large, positive impacts on cognitive and socioemotional development through third grade among the children of former participant mothers, including improved mathematics skills and reductions in withdrawn and aggressive behavior...

Endocrine Disrupting Substances (EDS) may have certain biological effects including delayed effects, multigenerational effects, and may display Non-Monotonic Dose Response (NMDR) relationships that require careful consideration when determining environmental hazards. EDS can have specific and profound effects when exposure occurs during sensitive windows of the lifecycle (development, reproduction). This creates the potential for delayed effects that manifest when exposure has ceased, possibly in a different life stage...

Patient acuity in hospital settings continues to increase, and there is greater emphasis on patient outcomes. The current nursing workforce is comprised of four distinct generational cohorts that include veterans, baby boomers, millennials, and generation Xers. Each group has unique characteristics that add complexity to the workforce and this can add challenges to providing optimal patient care. Team building is one strategy to increase mutual understanding, communication, and respect, and thus potentially improve patient outcomes...

Importance: Despite its high heritability, few risk genes have been identified for attention-deficit/hyperactivity disorder (ADHD). Brain-based phenotypes could aid gene discovery. There is a myriad of structural and functional connections that support cognition. Disruption of such connectivity is a key pathophysiologic mechanism for ADHD, and identifying heritable phenotypes within these connections could provide candidates for genomic studies. Objective: To identify the structural and functional connections that are heritable and pertinent to ADHD...

Occupational therapists need to be cognizant of evidence-based role balance advice and strategies that women with multigenerational caring responsibilities can implement independently or with minimal assistance, as role balance may not be the primary goal during many encounters with this population. Hence, this study aimed to identify the viewpoints on the most helpful role balance strategies for working sandwich generation women, both from their own perspectives and from the perspective of occupational therapists...

RATIONALE: In a bid to develop a mass spectrometer using ac frequency scanning for ion isolation, ion activation, and ion ejection, we have developed scan functions for each process using the inverse Mathieu q scan. METHODS: Ion isolation is accomplished by frequency hopping, that is, by skipping past the ranges of frequencies corresponding to the ions to be isolated during the frequency sweep. Multigenerational collision-induced dissociation is demonstrated by scanning the frequency of excitation from low to high so that multiple generations of product ions can be observed in the product ion mass spectra...

Natal philopatry, the return of individuals to their natal area for reproduction, has advantages and disadvantages for animal populations. Natal philopatry may generate local genetic adaptation, but it may also increase the probability of inbreeding that can compromise persistence. Although natal philopatry is well documented in anadromous fishes, marine fish may also return to their birth site to spawn. How philopatry shapes wild fish populations is, however, unclear because it requires constructing multigenerational pedigrees that are currently lacking for marine fishes...

BACKGROUND: The search for genetic factors underlying autism spectrum disorders (ASD) has led to the identification of hundreds of genes containing thousands of variants that differ in mode of inheritance, effect size, frequency, and function. A major challenge involves assessing the collective evidence in an unbiased, systematic manner for their functional relevance. METHODS: Here, we describe a scoring algorithm for prioritization of candidate genes based on the cumulative strength of evidence for each ASD-associated variant cataloged in AutDB (also known as SFARI Gene)...

In recent years, sociological research investigating grandparent effects in three-generation social mobility has proliferated, mostly focusing on the question of whether grandparents have a direct effect on their grandchildren's social attainment. This study hypothesizes that prior research has overlooked family structure as an important factor that moderates grandparents' direct effects. Capitalizing on a counterfactual causal framework and multigenerational data from the Panel Study of Income Dynamics, this study examines the direct effect of grandparents' years of education on grandchildren's years of educational attainment and heterogeneity in the effects associated with family structure...

Building on research examining "boomerang" adult children, I examine multigenerational living among young parents. Returning home likely differs between young mothers and fathers given variation in socioeconomic characteristics, health and risk-taking, their own children's coresidence, and union stability. Using the National Longitudinal Survey of Youth 1997 (NLSY97), I find that more than 40% of young parents (N = 2,721) live with their own parents at first birth or subsequently. Mothers are generally less likely to move home than fathers but only when not controlling for child coresidence and union stability...

BACKGROUND: Patients with bipolar disorder from the US have more early-onset illness and a greater familial loading for psychiatric problems than those from the Netherlands or Germany (abbreviated here as Europe). We hypothesized that these regional differences in illness burden would extend to the patients siblings. METHODS: Outpatients with bipolar disorder gave consent for participation in a treatment outcome network and for filling out detailed questionnaires...
