The article describes self-assembly of a series of unsymmetrical bola-shape π-amphiphiles (NDI-1, NDI-1a, NDI-2, NDI-3 and NDI-4) consisting of a hydrophobic naphthalene-diimide (NDI) chromophore attached with a non-ionic hydrophilic wedge and an anionic head group in the two opposite arms of the central NDI. By design only a single hydrazide group is linked either on the ionic or non-ionic arm of the NDI. NDI-1 and NDI-1a are regioisomers differing only in the location of the hydrazide group, placed in the non-ionic or ionic arm, respectively...

Synchronized movement is a ubiquitous feature of dance and music performance. Much research into the evolutionary origins of these cultural practices has focused on why humans perform rather than watch or listen to dance and music. In this study, we show that movement synchrony among a group of performers predicts the aesthetic appreciation of live dance performances. We developed a choreography that continuously manipulated group synchronization using a defined movement vocabulary based on arm swinging, walking and running...

Cubital tunnel syndrome is the second most common nerve compression syndrome observed in the upper extremity. Mechanical irritation of the ulnar nerve is also found in the upper and the lower arm even though cubital tunnel syndrome is documented most of the time. Apart from clinical examination electrophysiological testing is the most important contributor to the therapy decision. Depending on the clinical manifestation conservative treatment with elbow splinting may be appropriate. In the event of persistent or advanced nerve irritation surgical decompression may be the sensible intervention...

BACKGROUND: The first-line recommendation for treatment of acute iliofemoral deep vein thrombosis (IFDVT) is catheter-directed or pharmaco-mechanical thrombolysis (CDT/PCDT). Recent analysis of surgical thrombectomy has shown comparable results. However this procedure is not commonly given as much importance as interventional techniques. We analyzed patient outcome of surgical thrombectomy using modern endovascular techniques in both the short and long term. METHODS: All consecutive patients who underwent surgical thrombectomy at our institution between April 2008 and April 2017 were included...

The oxytocin (OT)-related serotonergic system is thought to play an important role in the etiology and social symptoms of autism spectrum disorder (ASD). However, no evidence exists for the relation between the prosocial effect of chronic OT administration and the brain serotonergic system. Ten male subjects with ASD were administered OT for 8-10 weeks in an open-label, single-arm, non-randomized, uncontrolled manner. Before and during the OT treatment, positron emission tomography was used with the ((11)C)-3-amino-4-(2-[(demethylamino)methyl]phenylthio)benzonitrile((11)C-DASB) radiotracer...

In recent years marked progress has been made in our understanding of the critical biologic and immunologic pathways involved in psoriasis. Genetic studies have demonstrated that susceptibility to psoriasis involves components of both the adaptive and innate immune system and not surprisingly activation of both of these arms of the immune system is found in psoriatic skin. While adaptive immune responses predominate in chronic plaque psoriasis, innate and autoinflammatory responses dominate in pustular forms of psoriasis, with other clinical subtypes extending on a spectrum between plaque and pustular psoriasis...

Antiretroviral (ARV) therapy, comprising a backbone of two nucleos(t)ide reverse transcriptase inhibitors (NRTIs) plus another ARV, is the recognized standard of care (SOC), which has helped extend life expectancy in people living with HIV. In a quest to reduce lifelong drug exposure and minimize or avoid the toxicity of NRTIs, "NRTI-reducing" regimens have been investigated. This descriptive review assessing the results of NRTI-reducing strategies from the largest randomized trials focuses on virological efficacy, resistance, regimen safety (in terms of bone mineral density, renal function, lipids and central nervous system function) and simplicity...

Pseudomonas syringae pv. phaseolicola (Psph) Race 6 is a globally prevalent and broadly virulent bacterial pathogen with devastating impact causing halo blight of common bean (Phaseolus vulgaris L.). Common bean lines PI 150414 and CAL 143 are known sources of resistance against this pathogen. We constructed high-resolution linkage maps for three recombinant inbred populations to map resistance to Psph Race 6 derived from the two common bean lines. This was complemented with a genome-wide association study (GWAS) of Race 6 resistance in an Andean Diversity Panel of common bean...

BACKGROUND: Rapid cooling at procurement after cross-clamping has been the cornerstone of organ preservation. NanoICE is a new form of ice that has emerged in the food industry and is providing more efficient cooling and preservation than regular ice. We hypothesize that the use of NanoICE will accelerate the cooling process of the allograft and will be able to maintain a steady low temperature without causing any significant histologic damage. METHODS: In this randomized pilot study, 14 pigs were used to study the liver core/surface cooling in a non-survival organ procurement operation...

Diffuse large B-cell lymphoma (DLBCL) is the most common type of canine lymphoma and survival times are currently <1 year. Manipulation of the tumour microenvironment, of which the regulatory T cell (Treg) is a principal player, represents a potentially exciting way to curb the rapid proliferation of neoplastic cells. Tregs, characterized by the stable expression of the transcription factor FoxP3, suppress innate and adaptive arms of the immune response and represent a potential therapeutic target within neoplastic lymph nodes...

REVIEW
Riccardo Pizzo, Olivia F O'Leary, John F Cryan
Although there is much evidence for a role of GABAB receptors in the pathophysiology of anxiety, the underlying neuronal mechanisms are largely unclear. The GABAB receptor allosteric positive modulator, GS39783, exerts anxiolytic effects without interfering with GABAB-mediated modulation of body temperature, cognitive performance and locomotor activity thus offering advantages over GABAB receptor agonists. However, the precise neural circuits underlying the anxiolytic effects of GS39783 are unknown. The aim of the present study was to identify brain structures and associated neuronal circuits that are modulated by GS39783 under either basal or mild stress conditions...

A basket-integrated optical device is developed to consistently treat tubular tissue by centering an optical diffuser in the lumen. Four nitinol arms in conjunction with the optical diffusing applicator are deployed to induce homogeneous circumferential light emission and concentric photothermal coagulation on tracheal tissue. 1470-nm laser light is employed for the tissue testing at various irradiation conditions and evaluated in terms of thermal gradient and temperature evolution. Preliminary experiments on liver tissue demonstrate the concentric development of the radial thermal coagulation in the tissue (eccentric ratio = ~5...

BACKGROUND: Histologic assessment of mucosal disease activity has been increasingly used in clinical trials of treatment for Crohn's disease. However, the operating properties of the currently existing histologic scoring indices remain unclear. OBJECTIVES: A systematic review was undertaken to evaluate the development and operating characteristics of available histologic disease activity indices in Crohn's disease. SEARCH METHODS: Electronic searches of MEDLINE, EMBASE, PubMed, and the Cochrane Library (CENTRAL) databases from inception to 20 July 2016 were supplemented by manual reviews of bibliographies and abstracts submitted to major gastroenterology meetings (Digestive Disease Week, United European Gastroenterology Week, European Crohn's and Colitis Organisation)...
