independently predicted higher risk of stroke and heart failure from hospitalization until a 3-year follow-up. To better understand the pathophysiology of female patients with AMI and develop more effective management, more studies in this field are necessary in the future.

Ion channels are transmembrane proteins that play important roles in cell function regulation modulating ionic cell permeability. In megakaryocytes and platelets, regulated ion flows have been demonstrated to modulate platelet production and function. However, a relatively limited characterization of ion channel expression and function is available in the human megakaryocyte-platelet lineage.

We analyzed the expression and function of the large-conductance calcium and voltage-activated potassium channel K

1.1 (also known as Maxi-K, BK, slo1) in human megakaryocytes and platelets.

To investigate the functionality of K

1.1, we exploited different agonists (BMS-191011, NS1619, NS11021, epoxyeicosatrienoic acid isoforms) and inhibitors (iberiotoxin, penitrem A) of the channel.

In megakaryocytes, K

1.1 agonists determined a decreased proplatelet formation and altered interaction with the extracellular matrix. Analysis of the actin cytoskeleton demonstrated a significant decrease in megakaryocyte spreading and adhesion to collagen. In platelets, the opening of the channel K

1.1 led to a reduced sensitivity to agonists with blunted aggregation in response to ADP, with an inhibitory capacity additive to that of aspirin. The K

1.1 agonists, but not the inhibitors, determined a reduction of platelet adhesion and aggregation onto immobilized collagen underflow to an extent similar to that of aspirin and ticagrelor. The opening of the K

1.1 resulted in cell hyperpolarization impairing free intracellular calcium in ADP-stimulated platelets and megakaryocytes.

The present study reveals new mechanisms in platelet formation and activation, suggesting that targeting K

1.1 channels might be of potential pharmacological interest in hemostasis and thrombosis.

SR-717 agonist Herein, contrary to our common understanding, we find that 2D perovskites can perform photocatalytic H2 production from HI splitting more efficiently than their 3D counterparts. We observed sharp difference between 2D perovskites crystals with organic phenylalkylammonium cations of different lengths and the 3D counterparts in their stabilization behavior in aqueous solution. Moreover, we show that the organic cations length of the 2D perovskites affects the nanostructures, optoelectronic properties, and the charge transfer process significantly, which determines the photocatalytic activity of the 2D perovskites. Among the 2D perovskites under investigation, phenylmethylammonium lead iodide with the shortest organic cations achieved the best solar-to-chemical conversion efficiency of ca. 1.57 %, which is the highest value ever reported for hybrid perovskites.

The Withdrawal Assessment Tool (WAT-1) is one of the most widely used clinician-reported outcome measures to evaluate iatrogenic withdrawal symptoms (IWS) in critically ill children. However, the WAT-1's measurement properties have not been aggregated. Aggregating psychometric research on the WAT-1 will enhance appropriate use, and outline gaps for future empirical research. The aim of this systematic review is to critically appraise, compare, and summarize the measurement properties and evidence quality, and describe the interpretability and feasibility of the WAT-1 for identifying IWS symptoms in critically ill children.

A systematic search of Medline, Embase and CINAHL was conducted from inception to 15 April 2020. Study inclusion/exclusion, data extraction, and measurement property evidence and the modified GRADE quality scoring were applied according to the COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) guidelines.

Six studies were included in the review. The and interpretability.

The paediatric Haemophilia Activities List (pedHAL) was developed to measure activities and participation in children and youth with haemophilia. Results from international studies provide an opportunity to determine which items are universally important.

The aim of this study was to determine which items of the pedHAL are redundant to construct a shorter version of the pedHAL.

This study is a cross-sectional multicentre secondary analysis on pooled data of published studies using the pedHAL (7 domains, 53 items, optimum score 100) in children with haemophilia A/B aged 4-18years. To identify redundant items, the following aspects were evaluated floor and ceiling effects, proportions of missing and 'not applicable' responses, inter-item correlations, component loadings in an exploratory factor analysis, internal consistency and item-total correlations.

Data on 315 patients with haemophilia from 6 studies were evaluated. Median age was 12.2years) (range 4.0-18.0), 87.3% had severe haemophilia and 80.3% received prophylaxis. Median (IQR) pedHAL sum score was 96.7 (88.0-100). After a stepwise procedure, 31 items were removed, resulting in a pedHAL

of 22 items, representing all original 7 domains. Most remaining items belonged to the domains 'sitting/kneeling/standing' and 'functions of the legs'. The pedHAL

sum score was similar to the original pedHAL sum score, with small differences in 5 domains.

This clinimetric study resulted in >50% reduction of the length of the pedHAL. The 22-item pedHAL

reduces patient burden and is expected to capture the information on activities and participation. The pedHAL

needs validation in other populations.

We aimed to report the pathological features of T lymphocytes in autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy (GFAP-A).

A retrospective pathological analysis of patients with GFAP-A was performed.

Eight patients with GFAP-immunoglobulin G (IgG) and pathological data were included. Their biopsy findings were similar, and all showed marked lymphocytic infiltration in the white matter, with perivascular predominance. The lymphocytic infiltration was predominantly composed of CD8

T lymphocytes rather than CD4

T lymphocytes, except in one patient who had overlapping positive myelin oligodendrocyte glycoprotein-IgG. Unlike CD4

T cells, CD8

T cells were frequently observed adjacent to dystrophic neurons and astrocytes. There was also diffuse infiltration by CD68

and CD163

macrophages. CD8

astrocytes were identified in two samples, but no CD4

astrocytes were observed.

A predominance of CD8

T cells may be an important pathological and diagnostic feature in GFAP-A.

Meat products have superior sensorial perception, because of their molecular composition and fibrous structure. Current understanding in the science of food structuring has enabled the utilization of alternative or nonmeat protein ingredients to create novel structured matrices that could resemble the textural functionality of real meat. The physicochemical and structural changes that occur in concentrated protein systems during thermomechanical processing lead to the creation of a fibrous or layered meat-like texture. Phase transitions in concentrated protein systems during protein-protein, protein-polysaccharide, protein-lipid, and protein-water interactions significantly influence the texture and the overall sensory quality of meat analogs. This review summarizes the roles of raw materials (moisture, protein type and concentration, lipids, polysaccharides, and air) and processing parameters (temperature, pH, and shear) in modulating the behavior of the protein phase during the restructuring process (structure-function-process relationship). The big challenge for the food industry is to manufacture concept-based (such as beef-like, chicken-like, etc.) meat analogs with controlled structural attributes. link2 This information will be useful in developing superior meat analogs that fulfill consumer expectations when replacing meat in their diet.Despite universal health coverage in France, migrants face specific socioeconomic barriers that increase the likelihood of a suboptimal cascade of care for chronic hepatitis C virus (HCV) infection and impaired treatment effectiveness in this sub-population. We selected data collected from 2012 to 2018 from the ANRS CO22 HEPATHER prospective cohort study for chronic HCV participants with available data on treatment failure (defined as the presence of a detectable HCV-RNA load 12 weeks after their first DAA treatment ended). We performed multivariable Poisson regression models to test whether treatment failure rates differed significantly between HCV-infected migrants and non-migrants receiving DAA in France (cross-sectional analysis), while taking into account the former's world region of birth and other potential social vulnerability factors. link3 Among the study population's 7,879 patients, 5,829 (74%) were non-migrants and 2,050 (26%) migrants. Median [interquartile range] age was 57 [51-65] years, 4433 (56%) were men and 369 (5%) of the entire study population had treatment failure. After multivariable adjustment, only migrants from Central Asia were at higher risk of treatment failure than non-migrants (aIRR = 2.83; 95% CI [1.72, 4.65]). Results from this large-scale study performed in France suggest a higher risk of DAA treatment failure in migrants from Central Asia than in non-migrants and confirm the overall low treatment failure rate in chronic HCV patients treated with DAA (whether migrants or not). Simplified models of care taking into account language and cultural barriers are needed to improve DAA effectiveness in migrants from Central Asia.Most metallodrugs are prodrugs that can undergo ligand exchange and redox reactions in biological media. Here we have investigated the cellular stability of the anticancer complex [OsII [(η6 -p-cymene)(RR/SS-MePh-DPEN)] [1] (MePh-DPEN=tosyl-diphenylethylenediamine) which catalyses the enantioselective reduction of pyruvate to lactate in cells. The introduction of a bromide tag at an unreactive site on a phenyl substituent of Ph-DPEN allowed us to probe the fate of this ligand and Os in human cancer cells by a combination of X-ray fluorescence (XRF) elemental mapping and inductively coupled plasma-mass spectrometry (ICP-MS). The BrPh-DPEN ligand is readily displaced by reaction with endogenous thiols and translocated to the nucleus, whereas the Os fragment is exported from the cells. These data explain why the efficiency of catalysis is low, and suggests that it could be optimised by developing thiol resistant analogues. Moreover, this work also provides a new way for the delivery of ligands which are inactive when administered on their own.
