The structural diversity of tetrahedra networks of phosphates can greatly be enhanced by introduction of mixed N/O anion positions. LiPr2 P4 N7 O3 exemplifies the benefits of N/O mixed anion positions as it is the first rare-earth (oxo)nitridophosphate with a single-layered structure and a degree of condensation (atomic ratio of tetrahedra centers (P) to tetrahedra corners (N/O atoms)) of 2/5. The compound was prepared through high-pressure metathesis starting from PrF3 , LiPN2 , Li2 O, and PON using a hydraulic 1000t press and the multianvil technique...

Understanding uranium (U) mobility is vital to minimizing its concentrations in potential drinking water sources. In this study, we report spatial-seasonal variations in U speciation and concentrations in a multi-aquifer system under the impact of Sanggan River in Datong basin, northern China. Hydrochemical and H, O, Sr isotopic data, thermodynamic calculations, and geochemical modeling are used to investigate the mechanisms of surface water-groundwater mixing-induced mobilization and natural attenuation of U...

INTRODUCTION AND OBJECTIVES: Despite the prevalence of heart failure with preserved ejection fraction (HFpEF), there is currently no evidence-based effective therapy for this disease. This study sought to evaluate whether inspiratory muscle training (IMT), functional electrical stimulation (FES), or a combination of both (IMT + FES) improves 12- and 24-week exercise capacity as well as left ventricular diastolic function, biomarker profile, and quality of life in HFpEF. METHODS: A total of 61 stable symptomatic patients (New York Heart Association II-III) with HFpEF were randomized (1:1:1:1) to receive a 12-week program of IMT, FES, or IMT + FES vs usual care...

BACKGROUND: PaVOS is a randomized controlled trial (RCT) which aims to address the use of whole-body vibration exercise (WBV) in combination with parathyroid hormone 1-34 fragment teriparatide (PTH 1-34) treatment in patients with osteoporosis. PTH 1-34 is an effective but expensive anabolic treatment for osteoporosis. WBV has been found to stimulate muscle and bone growth. Animal studies have shown a beneficial effect on bone when combining PTH 1-34 with mechanical loading. A combined treatment with PTH 1-34 and WBV may potentially have beneficial effects on bone and muscles, and reduce fracture risk...

INTRODUCTION: In recent years, the early detection and treatment of the first episode of schizophrenia (FES) has attracted worldwide attention. In Japan, psychiatric care has changed to an open and accessible framework over the past decade. Therefore, the duration of untreated psychosis (DUP) is thought to have been shortened. The purposes of this study were to investigate whether recent DUP periods are shorter than they were 10 years ago and whether the DUP at present differs among psychiatric facilities...

An approach to the construction of diabatic free energy surfaces (FESs) for ultrafast electron transfer (ET) in a supramolecule with an arbitrary number of electron localization centers (redox sites) is developed, supposing that the reorganization energies for the charge transfers and shifts between all these centers are known. Dimensionality of the coordinate space required for the description of multistage ET in this supramolecular system is shown to be equal to N - 1, where N is the number of the molecular centers involved in the reaction...

Pyrite (FeS2 ) is a promising electrode material for lithium ion batteries (LIBs) because of its high natural availability, low toxicity, cost-effectiveness, high theoretical capacity (894 mA h g-1 ) and high theoretical specific energy density (1270 W h kg-1 , 4e- /FeS2 ). Nevertheless, the use of FeS2 in electrochemical capacitors was restricted due to fast capacity fading as a result of polysulfide (S/Sn 2- ) formation during the initial electrochemical cycling. In order to avoid the formation of polysulfides, we employed the strategy of utilizing an ether based electrolyte (1...

Objective of the study was to determine the effect of circuit gait training versus traditional gait training on mobility performance and quality of life in sub-acute and chronic stroke patients. A randomized control trial was conducted and stroke patients of either gender having 2-4 score on Rankin Modified Scale and able to stand 10 seconds were included in study. A total of 32 individuals were randomly assigned into two groups. They were assigned a 40-50 min/session for 3-4 days/week over length of 06 weeks...

IGF-1 receptor (IGF-1R) and integrin cooperative signaling promotes cancer cell survival, proliferation, and motility, but whether this influences cancer progression and therapy responses is largely unknown. Here we investigated the non-receptor tyrosine adhesion kinase FES-related (FER), following its identification as a potential mediator of sensitivity to IGF-1R kinase inhibition in a functional siRNA screen. We found that FER and the IGF-1R co-locate in cells and can be co-immunoprecipitated. Ectopic FER expression strongly enhanced IGF-1R expression and phosphorylation on tyrosines 950 and 1131...

The sulfide catalyst is a subject of great interest in developing a MgH2 system as a potential hydrogen storage medium. In this work, FeS2 micro-spheres were successfully prepared by the surfactant-assisted solvothermal method, and later were ball milled with MgH2 to fabricate the MgH2 -16.7 wt% FeS2 composite. FeS2 addition could dramatically improve both the hydrogenation and dehydrogenation kinetics, and lower the dehydrogenation temperature of MgH2 as well. The MgH2 -16.7 wt% FeS2 composite could absorb 3...

Background: Historically, research investigating neural correlates of mentalizing deficits in schizophrenia has focused on patients who have been ill for several years with lengthy exposure to medication. Little is known about the neural and behavioral presentations of theory-of-mind deficits in schizophrenia, shortly after the first episode of psychosis. Methods: We investigated social cognition in 17 recently diagnosed first-episode schizophrenia (FES) patients with little or no exposure to antipsychotic medication and 1:1 matched healthy controls...

High specific activity is often a significant requirement for radiopharmaceuticals. To achieve that with18 F-labeled probes, it is mandatory to start from no-carrier-added fluoride and to reduce to a minimum the amount of precursor in order to decrease the presence of any pseudo-carrier. In the present study a feasible and efficient method for microscale one-pot radiosynthesis of18 F-labeled probes is described. It allows a substantial reduction in precursor, solvent and reagents, thus reducing also possible side reaction in the case of base-sensitive precursors...

OBJECTIVES: To determine whether associations of calf muscle density with physical function are independent of other determinants of functional decline in overweight and obese older adults. METHODS: This was a secondary analysis of a cross-sectional study of 85 community-dwelling overweight and obese adults (mean±SD age 62.8±7.9 years; BMI 32.3±6.1 kg/m2; 58% women). Peripheral quantitative computed tomography assessed mid-calf muscle density (66% tibial length) and dual-energy X-ray absorptiometry determined visceral fat area...

The thermal decomposition of free cationic iron-sulfur clusters Fex Sy + (x = 0-7, y = 0-9) is investigated by collisional post-heating in the temperature range between 300 and 1000 K. With increasing temperature the preferential formation of stoichiometric Fex Sy + (y = x) or near stoichiometric Fex Sy + (y = x ± 1) clusters is observed. In particular, Fe4 S4 + represents the most abundant product up to 600 K, Fe3 S3 + and Fe3 S2 + are preferably formed between 600 K and 800 K, and Fe2 S2 + clearly dominates the cluster distribution above 800 K...

AIM: Early clinical response predicts symptomatic remission and recovery in the maintenance treatment phase of first-episode schizophrenia (FES). However, little is known about predictors of symptomatic remission during acute treatment of severely ill patients with FES. Here, we conducted a secondary analysis of our retrospective observational study, which examined response, remission and treatment-resistance rates in seriously ill patients with FES spectrum disorders involuntarily hospitalized and treated with algorithm-based pharmacotherapy...

High level spinal cord injury (SCI) results in a very limited innervated skeletal muscle mass that strongly reduces exercise capacity. Our recent work showed that when adding functional electrical stimulation (FES) of the paralyzed legs (hybrid FES exercise) to produce higher exercise capacity, peak ventilation became a limiting factor to training-induced improvement in aerobic capacity. Our assumption was that the systemic adaptations to exercise training are delimited by the maximal ventilation that can be achieved...
