#1
Undine E Lang, Marc Walter
The depressive state has been characterised as one of elevated inflammation, changed cardiovascular parameters and a deranged metabolic situation all of which holds promise for a better understanding and handling of treatment-resistance in affective disorders as well as for future developments in treatment algorithms. In this context several biomarkers are differentially regulated by antidepressant treatment and connected to metabolic, inflammatory, cardiovascular and apoptotic components of the pathophysiology, i...

Motivation: Capturing association patterns in gene expression levels under different conditions or time points is important for inferring gene regulatory interactions. In practice, temporal changes in gene expression may result in complex association patterns that require more sophisticated detection methods than simple correlation measures. For instance, the effect of regulation may lead to time-lagged associations and interactions local to a subset of samples. Furthermore, expression profiles of interest may not be aligned or directly comparable (e...

Paolo Zardi, Klaus Wurst, Giulia Licini, Cristiano Zonta
Enantiomeric excess determination is crucial in many aspects of science ranging from synthesis to materials. Within this subject, the use of molecular sensors coupled with chiroptical techniques is a straightforward approach to the stereochemical analysis of chiral molecules, especially in terms of process immediacy and labor. Ste-reodynamic probes typically consist of racemic mixtures of rapidly interconverting enantiomeric conformers able to recognize a chiral analyte and greatly amplify its chiroptical readout...

BACKGROUNDCangrelor is an intravenous adenosine diphosphate (ADP) P2Y12 receptor antagonist, which has to be administered as a bolus followed by immediate infusion. Nevertheless, in clinical routine deviations from the correct practice, such as delayed infusion onset or interruptions during infusion, may occur. OBJECTIVE: The objective of the present study was to investigate the impact of administration delays on cangrelor concentration in a pharmacological simulation setting and to give possible solutions for the clinical practice...

Background: Erythropoiesis-stimulating agents (ESAs) are widely used to treat anaemia in patients with chronic kidney disease. The issue of ESA safety has been raised in multiple studies, with correlates derived for elevated cancer incidence and mortality. Whether these associations are related to ESA dose or the typology of the patient remains obscure. Methods: A multicentre, observational retrospective propensity score-matched study was designed to analyse the effects of weekly ESA dose in 1679 incident haemodialysis (HD) patients...

Regaining the ability to independently ambulate following a physical disability can increase functional ability and participation of patients in daily life. Gait trainers are assistive devices that enable body support and provide safety during gait. However, most conventional gait trainers are pre-configured to a constant position, therefore not suitable for practicing sit-to-stand function, and require assistance from a caregiver in order to mount the device from a sitting position. We therefore evaluated the effectiveness of a dynamically-adjusting gait trainer, designed to provide independence and safety during gait and various activities, in both lab setting and at home in 4 subjects (1 female, 3 males, ages 32-79 years) with limited ambulation...

Silvie Sevcikova, Tomas Vymazal, Miroslav Durila
BACKGROUND: Fluid resuscitation with crystalloid and colloid solutions is a common treatment in perioperative medicine. However, a variety of unbalanced or balanced solutions are used in clinical practice and there is still vivid debate going on regarding selection of optimal fluid with minimal negative effect on coagulation to minimize bleeding and blood transfusion requirements. The aim of the study was to investigate adverse effects of balanced crystalloids and colloids on coagulation measured by thromboelastometry in vitro...

Kyounghun Lee, Eung Je Woo, Jin Keun Seo
Electrical impedance tomography (EIT) provides functional images of an electrical conductivity distribution inside the human body. Since the 1980s, many potential clinical applications have arisen using inexpensive portable EIT devices. EIT acquires multiple trans-impedance measurements across the body from an array of surface electrodes around a chosen imaging slice. The conductivity image reconstruction from the measured data is a fundamentally ill-posed inverse problem notoriously vulnerable to measurement noise and artifacts...

In this paper, we proposed a number rule for 3d-4f and 4f cyclic coordination cages (CCCs); that is, CCCs consisting of vertex-sharing M4(μ3-OH)4 (M = 3d transition metal or 4f lanthanide ions) units should have 3 × n metal centers (abbreviated M3n), where n represents the number of the M4(μ3-OH)4 subunits. Under this number rule we reasoned that some species of CCCs, for example, the pentadecanuclear 3d-4f wheel and the pure 4f wheels with 9 or 18 centers, should practically have existed. However, there are no such complexes reported in the literature...

Pravanya Nandakumar, Alireza Mansouri, Sunit Das
The current World Health Organization classification of CNS tumors has made a tremendous leap from past editions by incorporating molecular criteria in addition to the pre-existing histological parameters. The revised version has had a particular impact on the classification of diffuse low-grade gliomas and their high-grade variants. The ATRX status is one of the critical markers that define the molecular classification of gliomas. In this review, we will first provide an overview of the role of ATRX in regular cell biology...

BACKGROUND: Heart failure (HF) is a global health problem. Guidelines for the management of HF have been established in Western countries and in Taiwan. However, data from the Taiwan Society of Cardiology-Heart Failure with reduced Ejection Fraction (TSOC-HFrEF) registry showed suboptimal prescription of guideline-recommended medications. We aimed to analyze the reason of non-prescription and clinical outcomes as a result of under-prescription of medications. METHODS: A total of 1509 patients hospitalized for acute HFrEF were recruited in 21 hospitals in Taiwan by the end of October 2014...

David J Warne, Ruth E Baker, Matthew J Simpson
Contact inhibition refers to a reduction in the rate of cell migration and/or cell proliferation in regions of high cell density. Under normal conditions, contact inhibition is associated with the proper functioning tissues, whereas abnormal regulation of contact inhibition is associated with pathological conditions, such as tumor spreading. Unfortunately, standard mathematical modeling practices mask the importance of parameters that control contact inhibition through scaling arguments. Furthermore, standard experimental protocols are insufficient to quantify the effects of contact inhibition because they focus on data describing early time, low-density dynamics only...
