ETHNOPHARMACOLOGICAL RELEVANCE: Aconitum carmichaelii (AC) is a common herbal medicine used as anti-inflammatory and analgesic agent in Eastern Asia. In Korea, a commercial processed AC (Aconibal(®)) is traditionally used to treat the symptoms of spondylosis deformans and rheumatic pain. AIM OF STUDY: Rheumatoid arthritis (RA) is systemic and auto-immune disease characterized by chronic inflammation. Methotrexate (MTX) is often the first-line therapy for RA. If MTX monotherapy is ineffective or RA is initially severe, adding a tumor necrosis factor (TNF)-α inhibitor to the treatment can be beneficial...

COPD patients are burdened with a daily risk of acute exacerbation and loss of control, which could be mitigated by effective, on-demand decision support tools. In this study, we present a machine learning-based strategy for early detection of exacerbations and subsequent triage. Our application uses physician opinion in a statistically and clinically comprehensive set of patient cases to train a supervised prediction algorithm. The accuracy of the model is assessed against a panel of physicians each triaging identical cases in a representative patient validation set...

BACKGROUND: We aimed to develop a risk score to improve the prediction of severe obesity in pediatric craniopharyngiomas (PCs). METHODS: 612 consecutive PCs were prospectively enrolled from 6 hospitals. Data from 404 participants were analyzed. Participants from 3 of the 6 hospitals (n=290) were used to develop a risk score. External validation of the developed risk score was conducted using the participants from the other 3 hospitals (n=114). Sequential logistic regression was used to develop and validate the risk score...

Compartmental models are the theoretical tool of choice for understanding single neuron computations. However, many models are incomplete, built ad hoc and require tuning for each novel condition rendering them of limited usability. Here, we present T2N, a powerful interface to control NEURON with Matlab and TREES toolbox, which supports generating models stable over a broad range of reconstructed and synthetic morphologies. We illustrate this for a novel, highly-detailed active model of dentate granule cells (GCs) replicating a wide palette of experiments from various labs...

Topological domain walls in dual-gated gapped bilayer graphene host edge states that are gate-tunable and valley polarized. Here we predict that plasmonic collective modes can propagate along these topological domain walls even at zero bulk density and possess a markedly different character from that of bulk plasmons. Strikingly, domain wall plasmons are extremely long-lived with plasmon lifetimes that can be orders of magnitude larger than the transport scattering time in the bulk at low temperatures. Importantly, long domain wall plasmon lifetimes persist even at room temperature with values up to a few picoseconds...

Quantitative analysis of biomolecular adsorption on a substrate is crucial for understanding biomolecular interactions. A quartz crystal microbalance (QCM) is a highly sensitive device to detect such interactions based on mass. However, the physicochemical analysis by the QCM alone often leads to overestimation of the actual adsorbed mass. Here a combined reflectometric interference spectroscopy (RIfS) and QCM is developed to simultaneously analyze adsorption of biomolecules. The RIfS detects the adsorbed mass based on the reflectance and predicts the adsorbed condition by modeling the reflection spectra using the transfer matrix method...

Electroactive interfaces distinguish electrochemistry from chemistry and enable electrochemical energy devices like batteries, fuel cells, and electric double layer capacitors. In batteries, electrolytes should be either thermodynamically stable at the electrode interfaces or kinetically stable by forming an electronically insulating but ionically conducting interphase. In addition to a traditional optimization of electrolytes by adding cosolvents and sacrificial additives to preferentially reduce or oxidize at the electrode surfaces, knowledge of the local electrolyte composition and structure within the double layer as a function of voltage constitutes the basis of manipulating an interphase and expanding the operating windows of electrochemical devices...

BACKGROUND: Interstitial lung disease (ILD) complicates the course of systemic sclerosis (SSc), representing the main cause of death in these patients. The identification of parameters that can predict the early onset and progression of ILD in SSc represents an unmet need in clinical practice. The study was designed to explore whether the surfactant proteins (SP) A and D may be used as noninvasive tools for the early identification of ILD in SSc. Alveolar exhaled nitric oxide (NO) was investigated as a surrogate marker of distal inflammation...

BACKGROUND: Oxidative stress (OS) has an important effect on the pathogenesis of atopic dermatitis (AD). Thiols are antioxidants that regulate intracellular redox metabolism and protect keratinocytes against OS damage in the stratum corneum. AIM: To investigate dynamic thiol-disulphide homeostasis (dTDH) as a novel OS parameter in children with AD, and its relationship with disease severity and chronicity. METHODS: Severity of AD was determined by using the instruments SCORing Atopic Dermatitis (SCORAD) and Eczema Area And Severity Index (EASI) upon enrolment in the study (SCORAD1 and EASI1 ) and after 1 year (SCORAD2 and EASI2 )...

BACKGROUND: (18)F-florbetapir uptake by brain tissue measured by positron emission tomography (PET) is accepted by regulatory agencies like the Food and Drug Administration (FDA) and the European Medicine Agencies (EMA) for assessing amyloid load in people with dementia. Its added value is mainly demonstrated by excluding Alzheimer's pathology in an established dementia diagnosis. However, the National Institute on Aging and Alzheimer's Association (NIA-AA) revised the diagnostic criteria for Alzheimer's disease and confidence in the diagnosis of mild cognitive impairment (MCI) due to Alzheimer's disease may be increased when using amyloid biomarkers tests like (18)F-florbetapir...

Graham Pawelec
Melanoma has long been recognized as a potentially immunogenic tumour, but only recently has it become clear that the reason for this resides in its many UV-induced mutations and expression of multiple autoantigens which can be targeted by the immune system. The first successful applications of immune-based treatments included passive immunotherapy using high-dose IL-2 and/or adoptive transfer of NK-cells, as well as active immunotherapy using whole cell-derived or peptide vaccines. In the intervening decades, it has become clear that these approaches can lead to durable responses in stage III/IV melanoma, and even to functional cures - but only in a vanishingly small fraction of patients...
