CRISPR/Cas9-mediated mutagenesis of CAROTENOID CLEAVAGE DIOXYGENASE 8 in tomato provides resistance against the parasitic weed Phelipanche aegyptiaca.
Broomrapes (Phelipanche aegyptiaca and Orobanche spp.) are obligate plant parasites that cause extreme damage to crop plants. The parasite seeds have strict requirements for germination, involving preconditioning and exposure to specific chemicals strigolactones [SLs] exuded by the host roots. SLs are plant hormones derived from plant carotenoids via a pathway involving the Carotenoid Cleavage Dioxygenase 8 (CCD8). Having no effective means to control parasitic weeds in most crops, and with CRISPR/Cas9 being an effective gene-editing tool, here we demonstrate that CRISPR/Cas9-mediated mutagenesis of the CCD8 gene can be used to develop host resistance to the parasitic weed P. aegyptiaca. Cas9/single guide (sg) RNA constructs were targeted to the second exon of CCD8 in tomato (Solanum lycopersicum L.) plants. Several CCD8Cas9 mutated tomato lines with variable insertions or deletions in CCD8 were obtained with no identified off-targets. Genotype analysis of T1 plants showed that the introduced CCD8 mutations are inherited. Compared to control tomato plants, the CCD8Cas9 mutant had morphological changes that included dwarfing, excessive shoot branching and adventitious root formation. In addition, SL-deficient CCD8Cas9 mutants showed a significant reduction in parasite infestation compared to non-mutated tomato plants. In the CCD8Cas9 mutated lines, orobanchol (SL) content was significantly reduced but total carotenoids level and expression of genes related to carotenoid biosynthesis were increased, as compared to control plants. Taking into account, the impact of plant parasitic weeds on agriculture and difficulty to constitute efficient control methods, the current study offers insights into the development of a new, efficient method that could be combined with various collections of resistant tomato rootstocks
Do Children\u27s Advocacy Centers improve familiesâ experiences of child sexual abuse investigations?
Abstract Objective The Children\u27s Advocacy Center (CAC) model of child abuse investigation is designed to be more child and family-friendly than traditional methods, but there have been no rigorous studies of their effect on children\u27s and caregiversâ experience. Data collected as part of the Multi-Site Evaluation of Children\u27s Advocacy Centers were used to examine whether CACs improve caregiversâ and children\u27s satisfaction with investigations. Methods Nonoffending caregiver and child satisfaction were assessed during research interviews, including the administration of a 14-item Investigation Satisfaction Scale (ISS) for caregivers. Two hundred and twenty-nine sexual abuse cases investigated through a CAC were compared to 55 cases investigated in communities with no CAC. Results Hierarchical linear regression results indicated that caregivers in CAC cases were more satisfied with the investigation than those from comparison sites, even after controlling for a number of relevant variables. There were few differences between CAC and comparison samples on children\u27s satisfaction. Children described moderate to high satisfaction with the investigation, while a minority expressed concerns about their experience. Conclusions The CAC model shows promise for improving familiesâ experiences, but to build upon this promise, agencies will need to systematize procedures for refining and adapting the model as new research becomes available
Development of an integrated economic and ecological framework for ecosystem-based fisheries management in New England

The definitive version was published in Progress in Oceanography 102 (2012): 93-101, doi:10.1016/j.pocean.2012.03.007.We present an integrated economic-ecological framework designed to help assess the implementation of ecosystem-based fisheries management (EBFM) in New England. We develop the framework by linking a computable general equilibrium (CGE) model of a coastal economy to an end-to-end (E2E) model of a marine food web for Georges Bank. We focus on the New England region using coastal county economic data for a restricted set of industry sectors and marine ecological data for three top level trophic feeding guilds: planktivores, benthivores, and piscivores. We undertake numerical simulations to model the welfare effects of changes in alternative combinations of yields from feeding guilds and alternative manifestations of biological productivity. We estimate the economic and distributional effects of these alternative simulations across a range of consumer income levels. This framework could be used to extend existing methodologies for assessing the impacts on human communities of groundfish stock rebuilding strategies, such as those expected through the implementation of the sector management program in the US northeast fishery. We discuss other possible applications of and modifications and limitations to the framework.This work was supported by the NOAA Saltonstall-Kennedy Grant Program (Award No. NA09NMF4270097), the MIT Sea Grant College Program (NOAA Award No. NA10OAR4170086, Subaward No. 5710002974), and the Johnson Endowment of the WHOI Marine Policy Center
Race, Socioeconomic Status, and Health The Added Effects of Racism and Discrimination
Higher disease rates for blacks (or African Americans) compared to whites are pervasive and persistent over time, with the racial gap in mortality widening in recent years for multiple causes of death. Other racial/ethnic minority populations also have elevated disease risk for some health conditions. This paper considers the complex ways in which race and socioeconomic status (SES) combine to affect health. SES accounts for much of the observed racial disparities in health. Nonetheless, racial differences often persist even at âequivalentâ levels of SES. Racism is an added burden for nondominant populations. Individual and institutional discrimination, along with the stigma of inferiority, can adversely affect health by restricting socioeconomic opportunities and mobility. Racism can also directly affect health in multiple ways. Residence in poor neighborhoods, racial bias in medical care, the stress of experiences of discrimination and the acceptance of the societal stigma of inferiority can have deleterious consequences for health.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/71908/1/j.1749-6632.1999.tb08114.x.pd
Schema therapy for emotional dysregulation: Theoretical implication and clinical applications
The term emotional dysregulation refers to an impaired ability to regulate unwanted
emotional states. Scientific evidence supports the idea that emotional dysregulation
underlies several psychological disorders as, for example: personality disorders, bipolar
disorder type II, interpersonal trauma, anxiety disorders, mood disorders and posttraumatic
stress disorder. Emotional dysregulation may derive from early interpersonal
traumas in childhood. These early traumatic events create a persistent sensitization of
the central nervous system in relation to early life stressing events. For this reason,
some authors suggest a common endophenotypical origin across psychopathologies.
In the last 20 years, cognitive behavioral therapy has increasingly adopted an interactiveontogenetic
view to explain the development of disorders associated to emotional
dysregulation. Unfortunately, standard Cognitive Behavior Therapy (CBT) methods are
not useful in treating emotional dysregulation. A CBT-derived new approach called
Schema Therapy (ST), that integrates theory and techniques from psychodynamic and
emotion focused therapy, holds the promise to fill this gap in cognitive literature. In this
model, psychopathology is viewed as the interaction between the innate temperament
of the child and the early experiences of deprivation or frustration of the subject\u2019s
basic needs. This deprivation may lead to develop early maladaptive schemas (EMS),
and maladaptive Modes. In the present paper we point out that EMSs and Modes
are associated with either dysregulated emotions or with dysregulatory strategies that
produce and maintain problematic emotional responses. Thanks to a special focus on
the therapeutic relationship and emotion focused-experiential techniques, this approach
successfully treats severe emotional dysregulation. In this paper, we make several
comparisons between the main ideas of ST and the science of emotion regulation, and
we present how to conceptualize pathological phenomena in terms of failed regulation
and some of the ST strategies and techniques to foster successful regulation in patients
Following the impact factor: Utilitarianism or academic compliance?
The use of impact factors has grown substantially in academia and publishing far beyond their original intended use. They are now used extensively in academic and research assessments as well as in the promotion of journals, publishers, institutions and individuals. The implications of such metricisation for understandings of research quality are discussed as well as for research strategies, the commercialisation of academic publishing, the disciplining of academic knowledge and publishing strategies, knowledge development and the further neoliberalisation of higher education. The paradoxes and problems of current and potential future directions are discussed including with respect to the development of open access publications
Congenital Stapes Anomalies with Normal Eardrum
ObjectivesA non-progressive and conductive hearing loss with normal eardrum, but no history of trauma and infection, is highly suggestive of a congenital ossicular malformation. Among ossicular anomalies, stapes anomaly is the most common. The purpose of this study is to describe patterns of stapes anomaly and to analyze its surgical outcome with special reference to its patterns.MethodsWe conducted a retrospective case review. The subjects comprised 66 patients (76 ears) who were decisively confirmed by the exploratory tympanotomy as congenital stapes anomalies without any anomalies of the tympanic membrane and external auditory canal. The preoperative and postoperative audiological findings, temporal bone computed tomography scan, and operative findings were analyzed.ResultsThere were 16 anomalous patterns of stapes among which footplate fixation was the most common anomaly. These 16 patterns were classified into 4 types according to the status of stapes footplate. Successful hearing gain was achieved in 51 out of 76 ears (67.1%) after surgical treatment.ConclusionFootplate fixation was usually bilateral, whereas stapes anomalies associated with other ossicular anomaly were usually unilateral. The success of the surgical treatment of stapes anomaly might depend on its developmental status of the footplate. Stapes anomalies were detected without any fixed patterns, therefore, it is quite possible to detect a large variety of patterns in future
