Nissim Cohen, Tuvia Horev
BACKGROUND: Can the entry of a policy entrepreneur challenge the equilibrium of a policy network and promote changes that might clash with the goals of powerful civil-servants and/or interest groups and, if so, why and how? Our goal is to examine two sides of the same coin: how does an in-depth analysis of Israel's dental care reform enrich our understanding of policy networks and policy entrepreneurship? Second, how does the literature on policy networks and policy entrepreneurship help us understand this reform? Based on a theoretical framework that appears in the literature of policy entrepreneurship and policy networks, we analyze the motivations, goals and strategies of the main actors involved in the process of reforming pediatric dental care in Israel...

Host-microbe interactions are influenced by complex host genetics and environment. Studies across animal taxa have aided our understanding of how intestinal microbiota influence vertebrate development, disease, and physiology. However, traditional mammalian studies can be limited by use of isogenic strains, husbandry constraints that result in small sample sizes and limited statistical power, reliance on indirect characterization of gut microbial communities from fecal samples, and concerns whether observations in artificial conditions are actually reflective of what occurs in the wild...

Upon oxygen limitation, the Bacillus subtilis ResE sensor kinase and its cognate ResD response regulator play primary roles in transcriptional activation of genes functioning in anaerobic respiration. The nitric oxide (NO)-sensitive NsrR repressor controls transcription to support nitrate respiration. In addition, the ferric uptake repressor (Fur) can modulate transcription under anaerobic conditions. However, whether these controls are direct or indirect has been investigated only in a gene-specific manner...

Seaweed cultivation not only provides economy benefits, but also remediates the environment contaminated by mariculture of animals (e.g., fish, shrimps). However, the response of microbial communities to seaweed cultivation is poorly understood. In this study, we analyzed the diversity, composition, and structure of water and sediment microbial communities at a seaweed, Gracilaria lemaneiformis, cultivation zone and a control zone near Nan'ao Island, South China Sea by MiSeq sequencing of 16S rRNA gene amplicons...

Heavy metals (Fe, Mn, Cr, Zn, Ni, Pb, Cu, Co and Cd) in the surface sediments of Cochin estuary, Southwest coast of India were analyzed to understand the spatio-temporal variation and contamination status via six sampling campaigns. Pollution indices like enrichment factor, geoaccumulation index and pollution load index inferred that the sediments of the northern arm of the estuary exhibited severe trace metal accumulation. Numerical sediment quality guidelines were applied to assess adverse biological effects of the trace metals, suggesting that occasional biological effect may occur due to Cr, Cu, Ni and Pb...

Previous studies showed that the repeated administration with a low dose of reserpine (RES) induces a gradual appearance of motor signs and cognitive deficits compatible with parkinsonism in rodents. Environmental stimulation has neuroprotective effects in animal models of neurodegenerative damage, including acutely induced parkinsonism. We investigated the effects of exposure to an enriched environment (EE) on motor, cognitive and neuronal (levels of tyrosine hydroxylase, TH and brain derived neurotrophic factor, BDNF) deficits induced by a progressive model of Parkinson's disease (PD) in mice...

Epigenetic mechanisms are important for facilitating gene-environment interactions in many disease etiologies, including Fetal Alcohol Spectrum Disorders (FASD). Extensive research into the role of DNA methylation and miRNAs in animal models has illuminated the complex role of these mechanisms in FASD. In contrast, histone modifications have not been as well researched, due in part to being less stable than DNA methylation and less well-characterized in disease. It is now apparent that even changes in transient marks can have profound effects if they alter developmental trajectories...

Gene regulation is a ubiquitous mechanism by which organisms respond to their environment. While organisms are often found to be adapted to the environments they experience, the role of gene regulation in environmental adaptation is not often known. In this study, we examine divergence in cis-regulatory effects between two Saccharomyces species, S. cerevisiae and S. uvarum, that have substantially diverged in their thermal growth profile. We measured allele specific expression (ASE) in the species' hybrid at three temperatures, the highest of which is lethal to S...

The natural environment serves as a reservoir of opportunistic pathogens. A well-established method for studying the epidemiology of such opportunists is multilocus sequence typing, which in many cases has defined strains predisposed to causing infection. Burkholderia multivorans is an important pathogen in people with cystic fibrosis (CF) and its epidemiology suggests that strains are acquired from non-human sources such as the natural environment. This raises the central question of whether the isolation source (CF or environment) or the multilocus sequence type (ST) of B...

The Aegilops kotschyi thermo-sensitive cytoplasmic male sterility (K-TCMS) system may facilitate hybrid wheat (Triticum aestivum L.) seed multiplication and production. The K-TCMS line is completely male sterile during the normal wheat-growing season, whereas its fertility can be restored in a high-temperature environment. To elucidate the molecular mechanisms responsible for male sterility/fertility conversion and candidate genes involved with pollen development in K-TCMS, we employed RNA-seq to sequence the transcriptomes of anthers from K-TCMS line KTM3315A during development under sterile and fertile conditions...

Regulatory T cells (Treg cells) perform suppressive functions in disparate tissue environments and against many inflammatory insults, yet the tissue-enriched factor(s) that influence Treg cell phenotype and function remain largely unknown. We have shown a vital role for transforming growth factor-β (TGF-β) signals in safe-guarding specific Treg cell functions. TGF-β signals were dispensable for steady-state Treg cell homeostasis and for Treg cell suppression of T cell proliferation and T helper-1 (Th1) cell differentiation...

Chlorpyrifos (CP) is one of the most widely used organophosphate pesticides in agriculture worldwide, but its extensive use has led to the contamination of various soil and water systems. Microbial bioremediation is considered to be one of the most viable options for the removal of CP from the environment; however, little is known about the soil bacterial diversity that degrade CP. Sequential soil and liquid culture enrichments enabled the isolation of bacterial CP degraders with sequence homologies to Xanthomonas sp...

Involvement by residents in professional medical organizations can enrich their training, but little data exist regarding the number and types of involvement opportunities available to otolaryngology residents. We sought to fill this gap in knowledge by quantifying the extent to which major otolaryngology-related organizations in the United States provide involvement opportunities to otolaryngology residents. Our analysis included 23 organizations and subspecialty societies. Results showed that many opportunities exist for residents to attend conferences and present research; however, fewer involvement and funding opportunities existed in any other leadership, health policy, or service-learning experiences...

Printing and dyeing wastewater with high content of organic matters, high colority, and poor biochemical performance is hard to be degraded. In this study, we isolated viable but non-culturable (VBNC) bacteria from printing and dyeing wastewater with the culture media contained resuscitation promoting factor (Rpf) protein secreted by Micrococcus luteus, counted the culturable cells number with the most probable number, sequenced 16S rRNA genes, and performed polymerase chain reaction-denaturing gradient gel electrophoresis...

A major challenge for assessment of water quality in tropical environments is the natural occurrence and potential growth of Fecal Indicator Bacteria (FIB). To gain a better understanding of the relationship between measured levels of FIB and the distribution of sewage-associated bacteria including potential pathogens in the tropics this study compared the abundance of FIB (Total coliforms and E. coli) and the Bacteroidales (HF183 marker) with bacterial community structure determined by next-generation amplicon sequencing...

Phthalic acid esters(PAEs) are ubiquitous in the environment and some of them are recognized as endocrine disruptors that cause concerns on ecosystem functioning and public health. Due to the diversity of PAEs in the environment, there is a vital need to detect the total concentration of PAEs in a timely and low-cost way. To fulfill this requirement, it is highly desired to obtain group-specific PAE binders that are specific to the basic PAE skeleton. In this study, for the first time we have identified the group-specific PAE-binding aptamers via rational designed target immobilization...

Since Ebbinghaus' classical work on oblivion and saving effects, we know that declarative memories may become at first spontaneously irretrievable and only subsequently completely extinguished. Recently, this time-dependent path toward memory-trace loss has been shown to correlate with different patterns of brain activation. Environmental enrichment (EE) enhances learning and memory and affects system memory consolidation. However, there is no evidence on whether and how EE could affect the time-dependent path toward oblivion...

Early social isolation (SI) produces a variety of emotional, behavioral and cognitive abnormalities. Conversely, environmental enrichment (EE), a complicated social and physical construct, offers beneficial effects on brain plasticity and development. However, whether or not exclusive physical EE is sufficient to reverse the adverse consequences of adolescent SI remains unclear. Here we reported that 1 month-old solitary mice housed in the EE for 8 weeks corrected spatial cognitive dysfunction, but did not ameliorate social interaction deficits and increased anxiety-like behavior...

The metabolic transformation of fatty acids to form oxylipids using 12/15lipoxygenase (LOX) can promote either resolving or non-resolving inflammation. However, the mechanism of how 12/15LOX interacts with PUFA (polyunsaturated fatty acids) in post-myocardial infarction (MI) healing is unclear. Here, we reported the role of 12/15LOX in post-MI cardiac remodeling in a PUFA (10% w/w, 22 Kcal) enriched environment. Wild-type (WT; C57BL/6J) and 12/15LOX null (12/15LOX(-/-)) male mice of 8-12-weeks age were fed PUFA-enriched diet for 1 month and subjected to permanent coronary artery ligation...
