Many bilaterally symmetrical animals develop genetically programmed left-right asymmetries. In vertebrates, this process is under the control of Nodal signaling, which is restricted to the left side by Nodal antagonists Cerberus and Lefty. Amphioxus, the earliest diverging chordate lineage, has profound left-right asymmetry as a larva. We show that Cerberus, Nodal, Lefty, and their target transcription factor Pitx are sequentially activated in amphioxus embryos. We then address their function by transcription activator-like effector nucleases (TALEN)-based knockout and heat-shock promoter (HSP)-driven overexpression...

High among the challenges facing mankind as the world population rapidly expands toward 9 billion people by 2050 is the technological development and implementation of sustainable agriculture and food systems to supply abundant and wholesome nutrition. In many low-income societies, women and children are the most vulnerable to food insecurity, and it is unequivocal that quality nutrition during the first 1000 d of life postconception can be transformative in establishing a robust, lifelong developmental trajectory...

Frontostriatal networks play critical roles in grounding action semantics and syntactic skills. Indeed, their atrophy distinctively disrupts both domains, as observed in patients with Huntington's disease (HD) and Parkinson's disease, even during early disease stages. However, frontostriatal degeneration in these conditions may begin up to 15 years before the onset of clinical symptoms, opening avenues for pre-clinical detection via sensitive tasks. Such a mission is particularly critical in HD, given that patients' children have 50% chances of inheriting the disease...

BACKGROUND AND PURPOSE: Flow disruption with the WEB device is an innovative technique for the endovascular treatment of wide neck bifurcation aneurysms. Good clinical practice trials have shown high safety of this treatment with good efficacy. Technical developments (single layer devices and smaller microcatheters) facilitate the treatment, potentially leading to enlargement of indications. This series is collecting aneurysms in "atypical" locations for WEB treatment and analyzing safety and efficacy of this treatment...

Marine natural products with antibiotic activity have been a rich source of drug discovery; however, the emergence of antibiotic-resistant bacterial strains has turned attention towards the discovery of alternative innovative strategies to combat pathogens. In many pathogenic bacteria, the expression of virulence factors is under the regulation of quorum sensing (QS). QS inhibitors (QSIs) present a promising alternative or potential synergistic treatment since they disrupt the signaling pathway used for intra- and interspecies coordination of expression of virulence factors...

Eric A Friedman, Lawrence O Gostin
The proposal for a global health treaty aimed at health equity, the Framework Convention on Global Health, raises the fundamental question of whether we can achieve true health equity, globally and domestically, and if not, how close we can come. Considerable knowledge currently exists about the measures required to, at the least, greatly improve health equity. Why, then, do immense inequities remain? Building on this basic question, we propose four areas that could help drive the health equity research and innovation agenda over the coming years...

We propose a cycles-breaking conceptual framework to guide perinatal research, interventions, and clinical innovations that can prevent or disrupt intergenerational cycles of childhood maltreatment and psychiatric vulnerability. The framework is grounded in literature, clinical observations, team science collaboration, and empirical research from numerous disciplines and is specific to the childbearing year. Adoption of the framework has the potential to speed the progress of research on the social problems of intergenerational childhood maltreatment and psychiatric vulnerability...

Medicine gets personal and tailor-made treatments are underway. Hospitals have started to advertise their advanced genomic testing capabilities and even their disruptive technologies to help foster a culture of innovation. The prediction in the lay press is that in decades from now we may look back and see 2017 as the year precision medicine blossomed. It is all part of the Precision Medicine Initiative that takes into account individual differences in people's genes, environments, and lifestyles.

There is a need to understand the nature of aggregation of cyclodextrins (CDs) with guest molecules in increasingly complex formulation systems. To this end an innovative application of Taylor dispersion analysis (TDA) and comparison with dynamic light scattering (DLS) have been carried out to probe the nature of ICT01-2588 (ICT-2588), a novel tumor-targeted vascular disrupting agent, in solvents including a potential buffered formulation containing 10% hydroxypropyl-β-cyclodextrin. The two hydrodynamic sizing techniques give measurement responses are that fundamentally different for aggregated solutions containing the target molecule, and the benefits of using TDA in conjunction with DLS are that systems are characterised through measurement of both mass- and z-average hydrodynamic radii...

Tumour-associated macrophages mainly comprise immunosuppressive M2 phenotypes that promote tumour progression besides anti-tumoural M1 subsets. Selective depletion or reprogramming of M2 may represent an innovative anti-cancer strategy. The actin cytoskeleton is central for cellular homeostasis and is targeted for anti-cancer chemotherapy. Here, we show that targeting G-actin nucleation using chondramide A (ChA) predominantly depletes human M2 while promoting the tumour-suppressive M1 phenotype. ChA reduced the viability of M2, with minor effects on M1, but increased tumour necrosis factor (TNF)α release from M1...

Myelin is a lipid-rich sheath formed by the spiral wrapping of specialized glial cells around axon segments. Myelinating glia allow for rapid transmission of nerve impulses and metabolic support of axons, and the absence of or disruption to myelin results in debilitating motor, cognitive, and emotional deficits in humans. Because myelin is a jawed vertebrate innovation, zebrafish are one of the simplest vertebrate model systems to study the genetics and development of myelinating glia. The morphogenetic cellular movements and genetic program that drive myelination are conserved between zebrafish and mammals, and myelin develops rapidly in zebrafish larvae, within 3-5days postfertilization...

In this study, the bisulfite-peroxydisulfate system (S(IV)/PDS) widely used in polymerization was innovatively applied for organic contaminants degradation in water. The addition of S(IV) into PDS system remarkably enhanced the degradation efficiency of bisphenol A (BPA, a frequently detected endocrine disrupting chemical in the environments) from 17.0% to 84.7% within 360 min. The degradation efficiency of BPA in the S(IV)/PDS system followed pseudo-first-order kinetics, with rate constant values ranging from 0...

Remarkable progress has been made in developing psychosocial interventions for eating disorders and other mental disorders. Two priorities in providing treatment consist of addressing the research-practice gap and the treatment gap. The research-practice gap pertains to the dissemination of evidence-based treatments from controlled settings to routine clinical care. Closing the gap between what is known about effective treatment and what is actually provided to patients who receive care is crucial in improving mental health care, particularly for conditions such as eating disorders...

BACKGROUND: Cryptomarkets represent an important drug market innovation by bringing buyers and sellers of illegal drugs together in a 'hidden' yet public online marketplace. We ask: How do cryptomarket drug sellers and buyers perceive the risks of detection and arrest, and attempt to limit them? METHODS: We analyse selected texts produced by vendors operating on the first major drug cryptomarket, Silk Road (N=600) alongside data extracted from the marketplace discussion forum that include buyer perspectives...

OBJECTIVE: In Canada, primary care reform has encouraged innovations, including nurse practitioners (NPs) and group medical visits (GMVs). NP-led GMVs provide an opportunity to examine barriers and enablers to implementing this innovation in primary care. DESIGN: An instrumental case study design (n=3): two cases where NPs were using GMVs and one case where NPs were not using GMVs, was completed. In-depth interviews with patients and providers (N=24) and 10 hours of direct observation were completed...

Human P-cadherin is a cell adhesion protein of the family of classical cadherins, the overexpression of which is correlated with poor prognosis in various types of cancer. Antibodies inhibiting cell-cell adhesion mediated by P-cadherin show clear therapeutic effect, although the mechanistic basis explaining their effectiveness is still unclear. Based on structural, physicochemical, and functional analyses, we have elucidated the molecular mechanism of disruption of cell adhesion by antibodies targeting human P-cadherin...

On November 27, 2005, Isabelle Dinoire underwent the world's first partial face transplant in Amiens (France) after a dog attack had left her face severely disfigured. The abrupt surgical leap found the medical community and society unprepared to deal with the scientific, ethical, and societal implications of a surgical procedure that was striving to transition from sci-fi novels to science. Today, 10 years and over 35 transplants later, public opinion has become accustomed to the concept of "face restoration" through transplantation...
