BACKGROUND To evaluation of diagnosis and treatment of pediatric patients with urachal remnants. METHODS Medical records of patients diagnosed with ural remnants between 2015-2019 were evaluated retrospectively. Age, gender, admission complaints, diagnosis, size of cysts, complications developed and treatment modalities were recorded. RESULTS Study population consisted of 15 cases including 7 girls. Most of the cases were asymptomatic and incidentally, the urachal remnants were detected by ultrasonography. The most common symptom in symptomatic patients was abdominal pain and umbilical discharge. Three patients required surgery and most of them were conservatively followed up. As complication infection and also bladder rupture were observed in one case. CONCLUSION Follow-up of patients with urachal remnants can be performed conservatively. The type of the complaints, the presence of clinical and radiological regression (if any), and the size of the urachal cyst are important for deciding the treatment during the follow-up. However, conservative follow-up is more prominent today, as shown in this study. This article is protected by copyright.

Herein, we describe the method's potential utility in more sensitively quantifying cardiovascular changes. We use a simple example of a human tilt table to illustrate these concepts. find more SPAR can be used on any approximately periodic waveform and may add value to experimental and clinical settings, where such signals are routinely collected. ABSTRACT Periodic physiological waveform data such as blood pressure, pulse oximetry and ECG are routinely sampled between 100-1000 Hz in preclinical research and in the clinical setting from a wide variety of implantable, beside and wearable monitoring devices. Despite the underlying numerical waveform data being captured at such high-fidelity, conventional analysis tends to reside in only reporting averages of minimum, maximum, amplitude and rate, as single point averages. Whilst these averages are undoubtedly of value, simplifying the data in this way means that most of the available numerical data is discarded. In turn, this may lead to subtle physiological changes being missed when investigating the cardiovascular system, over time. We have developed a mathematical method (Symmetric Projection Attractor Reconstruction) which uses all the numerical data, replotting and re-visualising it in a manner that allows unique quantification of multiple changes in waveform morphology and variability. We propose that the additional quantification of these features will allow the complex behaviour of the cardiovascular system to be more sensitively mapped under different physiological and pathophysiological settings.

To ensure their survival, these bacteria rely on chemosensory pathways to sense and respond to changing environmental conditions. These pathways constitute a highly sophisticated cellular control system in Bacteria and Archaea. Reflecting the complex life cycle of V. cholerae, this organism has three different chemosensory pathways that together contain over 50 proteins expressed under different environmental conditions. Only one of them is known to control motility, while the function of the other two remains to be discovered. Here, we provide an overview of the chemosensory systems in V. cholerae and the advances toward understanding their structure and function. © 2020 The Authors.

Incorporating non-canonical amino acids (ncAAs) into enzymes enables a dramatic expansion of their catalytic features. For this, quick identification of fully translated and correctly folded variants is crucial. Herein, we report the engineering of the enantioselectivity of an esterase utilizing several ncAAs. Key for the identification of active and soluble protein variants was the use of the split-GFP method, which is crucial as it allows simple determination of the expression levels of enzyme variants with ncAA incorporations by fluorescence. Several identified variants led to improved enantioselectivity or even inverted enantiopreference in the kinetic resolution of ethyl 3-phenylbutyrate. © 2020 WILEY-VCH Verlag GmbH & Co.

These additives act as chain-cappers of supramolecular polymers and feature one face as reactive as the BTA discotic to interact strongly with the polymer-end, whereas the other face is non-reactive and therefore impedes further polymerization. Such a design requires fine tuning of the conformational pre-organization of the amides and the steric hindrance of the motif. The chain-cappers studied are monotopic derivatives of BTA, modified by partial N -methylation of the amides or by positioning of a bulky cyclotriveratrylene cage on one face of the BTA unit. This study not only clarifies the interplay between structural variations and supramolecular interactions, but it also highlights the necessity to combine orthogonal characterization methods, spectroscopy and light scattering, to elucidate the structures and compositions of supramolecular systems. © 2020 WILEY-VCH Verlag GmbH & Co.

Robust research determining whether pharmacists have the capacity to offer such services in the Australian community pharmacy setting is lacking. This protocol details a mixed methods study that investigates the variation in pharmacists' daily tasks and the workspace they work in as a measure of their workload capacity for expanding pharmacy services. METHODS An observational time and motion study will be conducted in up to twenty community pharmacies in metropolitan and rural regions of Australia. A trained observer will follow a pharmacist and record the type, location and duration of tasks undertaken over the course of their working day. Data will be collected and analysed using the electronic Work Observation Method By Activity Timing (WOMBAT) tool. Pharmacists' work patterns will be described as time for each task, and by proportionating multitasking and interruptions.
