BACKGROUND: Placental Growth Factor (PGF) is important for wound-healing and vascular collaterogenesis. PGF deficiency is associated with preeclampsia, a hypertensive disease of human pregnancy. Offspring born to preeclamptic mothers display cognitive impairments and brain vascular and neurostructural deviations. Low PGF production during development may contribute to alterations in offspring cerebrovascular beds. Retina is a readily accessible part of the central nervous system with a well-described pattern of vascular development in mice...

Andrea L Dixon, Jeremiah W Busch
PREMISE OF THE STUDY: Direct tests of a species distribution model (SDM) were used to evaluate the hypothesis that the northern and southern edges of Mimulus bicolor's geographical range are limited by temperature and precipitation. METHODS: Climatic suitability was predicted using an SDM informed only by temperature and precipitation variables. These predictions were tested by growing plants in growth chambers with temperature and watering treatments informed by weather stations characteristic of environments at the geographic center, edges, and outside the range...

BACKGROUND: Tobacco smoking is a worldwide public health problem. In 2015, 26.3% of the Dutch population aged 18 years and older smoked, 74.4% of them daily. More and more people have access to the Internet worldwide; approximately 94% of the Dutch population have online access. Internet-based smoking cessation interventions (online cessation interventions) provide an opportunity to tackle the scourge of tobacco. OBJECTIVE: The goal of this paper was to provide an overview of online cessation interventions in the Netherlands, while exploring their effectivity, cost effectiveness, and theoretical basis...

BACKGROUND: Herpes simplex virus 1 (HSV-1) infection can result in a life-threatening condition known as herpes simplex encephalitis (HSE). Trafficking patterns by which the virus reaches the central nervous system (CNS) following ocular infection are unresolved. We evaluated early viral dissemination pathways following ocular infection that involve trafficking to the olfactory bulb (OB). Additionally, we have characterized the capacity of HSV-1 to establish latency within OB tissue and profiled the local T lymphocyte response over the course of the acute infection into latency...

CONTEXT: Intraosseous (IO) access is an established route of administration in resuscitation situations. Patients with serious poisoning presenting to the emergency department may require urgent antidote therapy. However, intravenous (IV) access is not always readily available. OBJECTIVE: This study reviews the current evidence for IO administration of antidotes that could be used in poisoning. The primary outcome was mortality as a surrogate of efficacy. Secondary outcomes included hemodynamic variables, electrocardiographic variables, neurological status, pharmacokinetics outcomes, and adverse effects as defined by each article...

BACKGROUND AND AIMS: Little research has examined the relationship between incentives used by gambling venues to attract customers and the experience of gambling related harm. Organized and subsidized bus tours are a common example of such incentives. The aim of this study was to examine whether bus tour patronage was associated with increased odds of problem gambling among older adults. This study also compared rates of bus tour use by sociodemographic characteristics and gambling behaviours...

BACKGROUND: Transverse myelitis (TM) is an immune-mediated disorder of the spinal cord that affects adults and children and that causes motor, sensory and autonomic dysfunction. There is a prolonged recovery phase, which may continue for many years. Neuromyelitis optica (NMO) is an uncommon relapsing inflammatory central nervous system condition in which TM can be the first presenting symptom. As TM and NMO affect many patients in the prime of their working life, the disorder can impose a significant demand on health resources...

The beta-secretase (BACE1) initiates processing of the amyloid precursor protein (APP) into Aβ peptides, which have been implicated as central players in the pathology of Alzheimer disease. BACE1 has been described as a copper-binding protein and its oligomeric state as being monomeric, dimeric, and/or multimeric, but the native cellular stoichiometry has remained elusive. Here, by using single-molecule fluorescence and in vitro cross-linking experiments with photo-activatable unnatural amino acids, we show that full-length BACE1, independently of its subcellular localization, exists as trimers in human cells...

The presence in crystallized proteins of a local anchoring between the side chain of a His residue, located in the central position of a γ- or β-turn, and its local main chain environment, was assessed by the comparison of protein structures with relevant isolated model peptides. Gas phase laser spectroscopy, combined with relevant quantum chemistry methods, was used to characterize the γ- and β-turn structures in these model peptides. A conformer-selective NH stretch infrared study provided evidence for the formation in vacuo of two types of short-range H-bonded motifs, labelled ε-6(δ) and δ-(δ)7/π(H), bridging the His side chain (in its gauche+ rotamer) to the neighbouring NH(i) and CO(i) sites of the backbone; each side chain-backbone motif was found to be specific of the tautomer (ε or δ) adopted by the His side chain in its neutral form...

With the increased incidence of cancers due to an aging population, and a prolonged survival thanks to advances in cancer treatments, new therapeutic challenges have arisen. The management of symptoms, the tolerance of increasingly effective oncologic treatments and, finally, quality of life are central concerns of patients and their loved ones. Supportive care in oncology has helped meet these challenges, offering a holistic approach, encompassing somatic, psychiatric and social aid. Inaugurated in 2005, the oncologic supportive care unit of the Geneva University Hospitals allows many cancer patients access to a team of multidisciplinary care-givers to help meet their needs...

Chromosomes present one of most challenging of all substrates for biochemical study. This is because genomic DNA is physically associated with an astonishing collection of nuclear factors, which serve to both store the nucleic acid in a stable form, but also grant access to the information it encodes when needed. Understanding this complex molecular choreography is central to the field of epigenetics. One of the great challenges in this area is to move beyond correlative type information, which is now in abundant supply, to the point where we can truly connect the dots at the molecular level...

In ultrasound-guided central venous catheterization, there is no standard technique either for the needle tip visualization or for the adequate needle angle and entry to the skin with short-axis view under out-of-plane technique. In the present study, we propose a novel technique named "stepwise flashing with triangulation", and the efficacy of this technique is assessed. Before and after a didactic session in which the technique was explained, 12 novice residents were asked to position the needle tip on or into the imitation vessels and to avoid deeper penetration by using an agar tissue phantom with ultrasound guidance...

Thoracic endovascular repair is considered the first-line treatment in complicated acute type B dissection. Central venous catheters provide valuable vascular access during endovascular treatments. However, central venous catheters are not without complications. Herein, we report a case of central venous catheter insertion into the false lumen of a complicated acute type B aortic dissection by direct aortic puncture. The tip of the central venous catheter was in the false lumen. The central venous catheter was left in place initially and was removed after graft stent deployment...

Background and Aims: Paper mulberry or Broussonetia papyrifera (L.) L'Hér. ex Vent. (Moraceae) is a dioecious species native to continental South-east Asia and East Asia, including Taiwan, that was introduced to the Pacific by pre-historic voyagers and transported intentionally and propagated asexually across the full range of Austronesian expansion from Taiwan to East Polynesia. The aim of this study was to gain insight into the dispersal of paper mulberry into Oceania through the genetic analysis of herbaria samples which represent a more complete coverage of the historical geographical range of the species in the Pacific before later introductions and local extinctions occurred...

Motivation: In higher eukaryotes, protein-DNA binding interactions are the central activities in gene regulation. In particular, DNA motifs such as transcription factor binding sites are the key components in gene transcription. Harnessing the recently available chromatin interaction data, computational methods are desired for identifying the coupling DNA motif pairs enriched on long-range chromatin-interacting sequence pairs (e.g. promoter-enhancer pairs) systematically. Results: To fill the void, a novel probabilistic model (namely, MotifHyades) is proposed and developed for de novo DNA motif pair discovery on paired sequences...

This article considers the relationship between the decriminalization of abortion and women's access to abortion services. It focuses on the four Australian jurisdictions which are, with Canada, the only jurisdictions in the world where abortion has been removed from the criminal law. This paper draws on documentary evidence and an oral history project to give a "before and after" account of each jurisdiction. The paper assumes that the meaning and impact of decriminalization must be assessed in each local context...
