Influenza viruses are respiratory pathogens that are responsible for seasonal influenza and sporadic influenza pandemic. The therapeutic efficacy of current influenza vaccines and small molecule antiviral drugs is limited due to the emergence of multidrug-resistant influenza viruses. In response to the urgent need for the next generation of influenza antivirals, we utilized a fast-track drug discovery platform by exploring multi-component reaction products for antiviral drug candidates. Specifically, molecular docking was applied to screen a small molecule library derived from the Ugi-azide four-component reaction methodology for inhibitors that target the influenza polymerase PAC -PB1N interactions...

Motivation: PCR-based DNA enrichment followed by massively parallel sequencing is a straightforward and cost effective method to sequence genes up to high depth. The full potential of amplicon based sequencing assays is currently not achieved as analysis methods do not take into account the source amplicons of the detected variants. Tracking the source amplicons has the potential to identify systematic biases, enhance variant calling and improve the designs of future assays. Results: We present Nimbus, a software suite for the analysis of amplicon based sequencing data...

Kinesin-1 is a nanoscale molecular motor that walks towards the fast-growing (plus) ends of microtubules, hauling molecular cargo to specific reaction sites in cells. Kinesin-driven transport is central to the self-organization of eukaryotic cells and shows great promise as a tool for nano-engineering1 . Recent work hints that kinesin may also play a role in modulating the stability of its microtubule track, both in vitro2,3 and in vivo4 , but the results are conflicting5-7 and the mechanisms are unclear. Here, we report a new dimension to the kinesin-microtubule interaction, whereby strong-binding state (adenosine triphosphate (ATP)-bound and apo) kinesin-1 motor domains inhibit the shrinkage of guanosine diphosphate (GDP) microtubules by up to two orders of magnitude and expand their lattice spacing by ~1...

BACKGROUND: Prolonged intubation following cardiac surgery is associated with significant morbidity. A fast-track extubation protocol primarily driven by bedside providers was instituted for all postoperative cardiac surgery patients to facilitate safe and expeditious extubation. METHODS: A retrospective review of 1581 cardiac surgery patients over an 8-year period was performed. Prior to 2011, non-protocolized standard perioperative management was utilized (n=807)...

BACKGROUND: Discrepancies are present in the literature on resting myocardial mechanics in patients with uncomplicated type 2 diabetes mellitus (T2DM). Data are noticeably sparse regarding circumferential function and torsional mechanics. Resting deformation imaging may not be sensitive enough to detect subtle dysfunctions. The aim of this study was thus to comprehensively evaluate myocardial mechanics in patients with T2DM at rest and to investigate whether dobutamine stress echocardiography could unmask functional alterations that would remain otherwise subtle at rest...

A description is presented on the management of a patient with an oesophageal neoplasm scheduled for oesophagectomy. Alloantibodies were detected during a blood components reservation procedure, which made it almost impossible to obtain compatible blood. Peri-operative anaemia management or "Patient Blood Management" should be routinely performed in all patients at transfusion risk. This strategy has been considered as one of the actions to bear in mind in fast-track surgery or enhanced recovery after surgery...

In this study we reported that the presence of functionalized multi-walled carbon nanotubes (FCNT-H) would greatly enhance the degradation of atrazine (ATZ), a model contaminant, in the Fe(III)-mediated Fenton-like system. Efficient ATZ degradation (>90%) was achieved within 30 min in the presence of 20 mg.L-1 FCNT-H, 2.0 mg.L-1 Fe(III), and 170 mg.L-1 H2 O2 , whereas negligible ATZ degradation occurred in FCNT-H free system. The structure and surface chemistry of FCNT-H and other CNTs were well characterized...

We report the personal eye gaze patterns of people engaged in face-to-face getting acquainted conversation. Considerable differences between individuals are underscored by a stability of eye gaze patterns within individuals. Results suggest the existence of an eye-mouth gaze continuum. This continuum includes some people showing a strong preference for eye gaze, some with a strong preference for mouth gaze, and others distributing their gaze between the eyes and mouth to varying extents. Additionally, we found evidence of within-participant consistency not just for location preference but also for the duration of fixations upon the eye and mouth regions...

BACKGROUND: Early detection of anastomotic leakage after esophagectomy has the potential to reduce morbidity and mortality. Prompt suspicion of leak may help to exclude patients from fast-track protocols, thereby avoiding early oral feeding and early hospital discharge which could aggravate the prognosis of a clinically occult leak. PATIENTS AND METHODS: Observational retrospective cohort study. Patients with diagnosis of esophageal cancer who underwent elective minimally invasive esophagectomy were included...

An important issue in the emerging field of multifrequency atomic force microscopy (MF-AFM) is the accurate and fast demodulation of the cantilever-tip deflection signal. As this signal consists of multiple frequency components and noise processes, a lock-in amplifier is typically employed for its narrowband response. However, this demodulator suffers inherent bandwidth limitations as high-frequency mixing products must be filtered out and several must be operated in parallel. Many MF-AFM methods require amplitude and phase demodulation at multiple frequencies of interest, enabling both z -axis feedback and phase contrast imaging to be achieved...

Background/Aims: Postoperative delirium (POD) is more frequent in elderly patients undergoing major cancer surgery. The interplay between individual clinical vulnerability and a series of perioperative factors seems to play a relevant role. Surgery is the first-line treatment option for cancer, and fast-track surgery (FTS) has been documented to decrease postoperative complications. The study sought to assess, after comprehensive geriatric assessment (CGA) and frailty stratification (Rockwood 40 items index), which perioperative parameters were predictive of POD development in elderly patients undergoing FTS for colorectal cancer...

We report an interpolation model to calculate the hydrodynamic force on tethered capsule-shaped cells in micro-fluidic flows near a surface. Our model is based on numerical solutions of the full Navier-Stokes equations for capsule-shaped objects considering their geometry, aspect ratio and orientation with respect to fluid flow. The model reproduced the results from computational fluid dynamic simulations, with an average error of <0.15 % for objects with an aspect ratio up to 5, and the model exactly reproduced the Goldman approximation of spherical objects close to a surface...

UNAIDS 90-90-90 targets and Fast-Track commitments are presented as precursors to ending the AIDS epidemic by 2030, through effecting a 90% reduction in new HIV infections and AIDS-related deaths from 2010 levels (HIV epidemic control). Botswana, a low to middle-income country with the third-highest HIV prevalence, and Australia, a low-prevalence high-income country with an epidemic concentrated among men who have sex with men (MSM), have made significant strides towards achieving the UNAIDS 90-90-90 targets...

OBJECTIVE: Assess the influence of background music tempo on driving performance. BACKGROUND: Music with a fast tempo is known to increase the level of arousal, whereas the reverse is observed for slow music. The relationship between driving performance and level of arousal was expected to take the form of an inverted U-curve. METHOD: Three experiments were undertaken to manipulate the musical background during driving. In Experiment 1, the driver's preferred music track played at its original and modified (plus or minus 30%) tempo were used together with the simple ticking of a metronome...

We have studied two model DNA oligonucleotide sequences which display contrasting degrees of heterogeneous melting using an optical temperature jump to trigger dehybridization and a nonlinear infrared (IR) spectroscopy probe to track the response of the helix ensemble. This approach offers base-sensitive structural insight through the unique vibrational fingerprint characteristic of each nucleobase as well as time resolution capable of following unfolding across nanoseconds to milliseconds. We observe pre-dissociation unzipping of the helical termini, loss of final dimer contacts, and rehybridization of the dissociated strands all in a single measurement...

Anticoagulation pharmacy has been dramatically altered with US Food and Drug Administration (FDA) approval of 5 direct oral anticoagulants, 1 novel reversal agent and, a second designated for fast-track approval. Trial data surrounding current trends in anticoagulant choice for VTE, reversal, and bridging are constantly redefining practice. Extended therapy for unprovoked VTE has expanded to include low-dose direct oral anticoagulants, aspirin, and the use of the HERDOO2 system to identify women who can stop anticoagulant therapy without increased risk of recurrent VTE...

Exposure to heavy-ion radiation during cancer treatment or space travel may cause cognitive detriments that have been associated with changes in neuron morphology and plasticity. Observations in mice of reduced neuronal dendritic complexity have revealed a dependence on radiation quality and absorbed dose, suggesting that microscopic energy deposition plays an important role. In this work we used morphological data for mouse dentate granular cell layer (GCL) neurons and a stochastic model of particle track structure and microscopic energy deposition (ED) to develop a predictive model of high-charge and energy (HZE) particle-induced morphological changes to the complex structures of dendritic arbors...
