A new method based on mixing and wounding of callus tissue was used to transfer plastid or nuclear DNA between cells. Methods alternative to sexual hybridization can be powerful tools for crop improvement. We have developed a new hybridization technology based on wounding a mixed population of cells of two parents growing in vitro as callus ("cell grafting"), and have demonstrated the utility of this system for plastid or nuclear genome transfer. In our proof-of concept experiments, non-organized growing tissue (callus) from tobacco var...

Conservation biology faces critical challenges that require collaborative approaches, including novel strategies to support interactions among actors in biodiversity conflicts. The goals of this study were to investigate the concept of common ground across multiple issues and to explore its practical application for the support of environmental management. We conceptually defined common ground as the areas of relevance underlying the suite of issues expressed by people regarding environmental management in a particular context...

Although studies have suggested that community social capital contributes to narrow income-based inequality in depression, the impacts may depend on its components. Our multilevel cross-sectional analysis of data from 42,208 men and 45,448 women aged 65 years or older living in 565 school districts in Japan found that higher community-level civic participation (i.e., average levels of group participation in the community) was positively associated with the prevalence of depressive symptoms among the low-income groups, independent of individual levels of group participation...

Interactions in the airway ecology of cystic fibrosis may alter organism persistence and clinical outcomes. Better understanding of such interactions could guide clinical decisions. We fitted logistic regression models using generalized estimating equations to longitudinal two-year patient cohorts in the Cystic Fibrosis Foundation Patient Registry, 2003-2011 to study associations between airway organisms present in each calendar year and their presence in the subsequent year. Models were adjusted for clinical characteristics and multiple observations per patient and tested for sensitivity to cystic fibrosis-specific treatments...

Yihan Wang, Christina Matz-Costa
This study explores the effect of positive and negative social support, social reciprocity, and subjective social status on the retirement satisfaction and health of retirees and gender differences therein. Using cross-sectional data from the 2010 and 2012 waves of the Health and Retirement Study (HRS), we found that social support seems to matter more for the retirement satisfaction and health of women, while social reciprocity matters more for the health of men and subjective social status for the retirement satisfaction of men...

Acquired Brain Injury (ABI) is one of the most common causes of disability and death in adults worldwide. After a period of rehabilitation, many ABI survivors still face complex mind/body conditions when they try to take up their former life again. Besides lasting visible impairments such as weakness and loss of body balance, there are often less obvious disabilities such as extreme fatigue, hypersensitivity for stimuli, memory, concentration and attention problems or personality changes. The aim of this paper is to understand how ABI survivors and their significant others renegotiate their engagements with everyday places, using the concepts of bio-geo-graphical disruption and flow...

Hannah Tough, Martin W G Brinkhof, Johannes Siegrist, Christine Fekete
OBJECTIVE: Persons with physical disabilities and their caregiving partners are at an increased risk of experiencing reduced life satisfaction. One potential explanation for this trend may be the potentially harmful effects of loneliness and poor relationship quality which this population often experience. To date, little is known about how the perceptions of loneliness and relationship quality affect life satisfaction in the disability and caregiving setting, furthermore the directionality of effect is not well understood...

The spread and varied impacts of the HIV/AIDS epidemic demonstrate the complex and reciprocal relationships between the socio-political and biophysical dimensions of human health. Yet even with increasing research and policy attention there remain critical gaps in the literature on how HIV-positive households manage health through their engagement with social and ecological systems. This is particularly urgent given improvements in the global response to the epidemic, whereby expanded access to antiretroviral therapy has extended the possibility for survival for years or decades...

Maternal reminiscing and remembering has a profound influence on the development of children's autobiographical remembering skills. The current study investigated the relationships between maternal memory specificity, maternal reminiscing and child memory specificity. Participants consisted of 40 mother-child dyads. Children's age ranged between 3.5 and 6 years. Mothers and children participated in individual assessments of autobiographical memory specificity. Dyads participated in a joint reminiscing task about three past emotional (happy, sad, stressful) events...

This study advances research on the role of personal networks as sources of financial and emotional support in immigrants' close personal ties beyond the immediate family. Because resource scarcity experienced by members of immigrant communities is likely to disrupt normatively expected reciprocal support, we explored multi-level predictors of exchange processes with personal network members that involve (1) only receiving support, (2) only providing support, and (3) reciprocal support exchanges. We focus on an understudied case of Central Asian migrant women in the Russian Federation using a sample of 607 women from three ethnic groups-Kyrgyz, Tajik, Uzbek-who were surveyed in two large Russian cities-Nizhny Novgorod and Kazan...

AIMS: Social interactions play an important role in our everyday life. Studies on children's quality of life (QoL) show that peer relations are associated with both positive and negative outcomes. Popularity defines the degree to which a child is liked by his or her peers, whereas reciprocal friendship occurs when two children mutually nominate each other as friends. The overall aim was to examine associations between peer relations and children's QoL. METHODS: Baseline data were from the Health Oriented Pedagogical Project (HOPP)...

Prostate cancer gene expression marker 1 (PCGEM1) is a prostate‑specific gene overexpressed in prostate cancer cells that promotes cell proliferation. To study the molecular mechanism of PCGEM1 function in hormone‑refractory prostate cancer, the interaction between myocyte enhancer factor 2 (MEF2) and PCGEM1 was assessed by a luciferase reporter assay and chromatin immunoprecipitation (ChIP) assay. In addition, the underlying mechanism of PCGEM1 regulating expression of microRNA (miR)‑148a in PC3 prostate cancer cells was evaluated...

PURPOSE: Pentraxin 3 (PTX3) is a vital regulator of innate immune function. Although plasma PTX3 concentrations are elevated with aerobic fitness, the cellular functions of PTX3 remain unknown in aerobically trained and untrained subjects. METHODS: Thirty individuals (aerobically trained = 15 and untrained = 15) participated in a maximal exercise protocol to examine ex vivo PTX3 production from isolated peripheral blood mononuclear cells (PBMCs) exposed to LPS or palmitate...

BACKGROUND: Penile erection is a complex reflex under spinal control and modulated by the brain. The hemodynamic events under autonomic control and the perineal muscles somatic activity are interconnected during the reflex erection at the spinal level, however if the afferent feedback on the corpus cavernosum pressure during an erection affects the somatic activity (perineal muscles contractions) and vice versa is not known. This study was aimed to test this hypothesis using a rat model...

This exploratory study is the first to identify content differences between youths' online chats with contact child sex offenders (CCSOs; seek to meet with youths) and those with fantasy child sex offenders (FCSOs; do not meet with youths) using statistical discourse analysis (SDA). Past studies suggest that CCSOs share their experiences and emotions with targeted youths (self-disclosure grooming tactic) and encourage them to reciprocate, to build trust and closer relationships through a cycle of self-disclosures...

Fusion genes resulting from chromosomal rearrangements represent a hallmark of childhood acute lymphoblastic leukemia (ALL). Unlike more common fusion genes generated via simple reciprocal chromosomal translocations, formation of the ETV6-ABL1 fusion gene requires 3 DNA breaks and usually results from an interchromosomal insertion. We report a child with ALL in which a single interchromosomal insertion led to the formation of ETV6-ABL1 and two novel fusion genes: AIF1L-ETV6 and ABL1-AIF1L. We demonstrate the prenatal origin of this complex chromosomal rearrangement, which apparently initiated the leukemogenic process, by successful backtracking of the ETV6-ABL1 fusion into the patient's archived neonatal blood...

Saar A M van der Laarse, Aneika C Leney, Albert J R Heck
A wide variety of protein post-translational modifications (PTMs) decorate cellular proteins, regulating their structure, interactions and ultimately their function. The density of co-occurring PTMs on proteins can be very high, where multiple PTMs can positively or negatively influence each others actions, nowadays termed PTM crosstalk. In this review we highlight recent progress in the area of PTM crosstalk, whereby we focus on crosstalk between protein phosphorylation and O-GlcNAcylation. These two PTMs largely target identical (i...

High molecular weight biotinylated dextran amine (BDA) has been used as a highly sensitive neuroanatomical tracer for many decades. Since the quality of its labeling was affected by various factors, here, we provide a refined protocol for the application of high molecular weight BDA for studying optimal neural labeling in the central nervous system. After stereotactic injection of BDA into the ventral posteromedial nucleus (VPM) of the thalamus in the rat through a delicate glass pipette, BDA was stained with fluorescent streptavidin-Alexa (AF) 594 and counterstained with fluorescent Nissl stain AF500/525...
