High-entropy alloy aerogels (HEAAs) combined with the advantages of high-entropy alloys and aerogels are prospective new platforms in catalytic reactions. However, due to the differences in reduction potentials and miscibility behavior of different metals, the realization of HEAAs with a single phase is still a great challenge. Herein, a series of HEAAs is fabricated via the freeze-thaw method as highly active and durable electrocatalysts for the carbon dioxide reduction reaction (CO2 RR). Especially, the PdCuAuAgBiIn HEAAs can achieve Faradaic efficiency (FE) of C1 products almost 100% from -0.7 to -1.1 V versus reversible hydrogen electrode (VRHE ), and a maximum FE for formic acid (FEHCOOH ) of 98.1% at -1.1 VRHE , outperforming PdCuAuAgBiIn high-entropy alloy particles (HEAPs) and Pd metallic aerogels (MAs). Specifically, the current density and FEHCOOH are almost 200 mA cm-2 and 87% in a flow cell. The impressive CO2 RR performance of the PdCuAuAgBiIn HEAAs is attributed to the strong interactions between the different metals and the surface unsaturated sites, which can regulate the electronic structures of different metals and allow the optimal HCOO* intermediate adsorption and desorption onto the catalysts surface to enhance HCOOH production. The work not only provides a facile synthetic strategy to fabricate HEAAs, but also opens the avenue for development of efficient catalysts and beyond.A novel facile, quick, and temperature-controlled sensor was constructed based on a polystyrene-poly-N,N-diethyl acrylamide-polystyrene (PS-PDEAM)/carboxylated multi-walled carbon nanotube (MWCNT) composite modified glass carbon electrode. The sensor achieves acetaminophen (AP) reversibility through better temperature sensitivity. PS-PDEAM shrinks when the temperature exceeds its lower critical temperature (LCST). When AP molecules pass through the modified interface, the electron transfer rate is accelerated, and the sensor is turned on. In the off state, the electrochemical response of AP cannot be detected. Under ideal experimental conditions, for composite modified films, there is a wide detection range of AP between 1.5-85.1 μM and 85.1-235.1 μM, and the limit of detection of acetaminophen is as low as 0.57 μM (S/N = 3). This method has been successfully applied to the determination of AP in tablets, and shows high stability, good reproducibility and excellent anti-interference ability. The on-off sensor opens up a wide range of possibilities for the use of temperature-sensitive polymers in electro-catalysis, sensors, and environmental pollutant monitoring.Hate crimes have severe consequences for the victims and for all members of the victim's social category. Prison programs must address the criminogenic needs of the participants, especially in this kind of crime, in order to prevent recidivism. This study seeks to understand the role of prejudice and aggression in the execution of hate crimes, in order to design effective interventions for hate crime offenders. Sociodemographic, criminological, and psychosocial variables were assessed in a sample of 33 hate crime offenders sentenced to prison or community service and in a group of 38 non-bias-motivated criminals (n = 71). The individuals convicted of hate crimes have higher reactive and proactive aggression, subtle prejudice, homophobia, and social dominance orientation. TP-0184 The implications of these results for the Penitentiary Administration programs will be discussed.
Diffusion-weighted imaging (DWI) is feasible in prenatal imaging, and it exhibits better contrast between the placenta and the myometrium compared to T2-weighted (T2W) images.
To compare magnetic resonance imaging (MRI) features of placenta accreta on T2W and DW imaging.
In this retrospective study, 42 pregnant patients who underwent prenatal MRI were included. MRI was performed on a Siemens 1.5-T scanner. T2W and DWI sequences in the axial, sagittal, and/or coronal planes were compiled for review. Two radiologists independently interpreted T2W and DW images for placenta accreta. T2W and DWI scores were calculated based on the presence of features and graded as low, intermediate, and high risk. The association between imaging features and placental invasion on pathology was calculated using chi-square tests. Sensitivity, specificity, and positive and negative predictive values (NPV) were compared between T2W and DWI interpretations. Inter-reader agreement between the two radiologists for T2W and DWI scores was calculated using Cohen's kappa coefficient.
Out of 42 pregnant patients, 10 were pathologically/surgically proven to have placenta accreta. There were no significant differences between T2W and DWI interpretations. Considering a cutoff >6 as positive, the T2W score had higher sensitivity (90% vs. 80%) and NPV (96.9% vs. 94.1%) than the DWI score. The specificity and positive predictive value were 100% for both scores. The inter-reader agreement of T2W score was higher (k = 0.943 vs. 0.882).
T2W and DWI are comparable in diagnosing placenta accreta spectrum. T2W sequences have higher sensitivity, NPV, and inter-reader agreement than DWI.

Estimate the prevalence and incidence of Attention Deficit Hyperactivity Disorder (ADHD) and analyze variations in its treatment across Spain.
Analyses were performed using IQVIA's clinical practice RealWorld Database, the electronic medical records of some 1 million patients from 2013 to 2018. MPH treatment was assessed using the Defined Daily Dose (DDD), MPH sales were extracted from IQVIA's Sell-Out database and the number of active psychiatrists from IQVIA's OneKey Database.
Significantly higher ADHD prevalence and incidence (1) in children than in adults and (2) in males compared to females. 91% of patients take MPH. Regional variations in MPH consumption range from 247 Daily Dose per Inhabitant (DDI) per 100,000 inhabitants to 414.
ADHD continues to be underdiagnosed and undertreated, particularly in adults, and more so in females. The lack of diagnostic tools for adults and the variations in treatment across the country need to be addressed.

Liposomes possess many attractive properties, such as easy processing, high biocompatibility, adaptable drug loading, and improved PK profiles. In recent decades, great efforts have been made in this field, and dozens of liposomal medicines have been marketed worldwide and many more are under preclinical or clinical investigations. Liposomes can enhance the aqueous dissolution and stability of the encapsulated drugs and modulate the in vivo fate of the drugs (e.g., prolonged half-life and increased drug accumulation in the pathological sites). Therefore, liposomal technology can improve the druggability of the candidates, enhance treatment efficacy and reduce side effects. This review discusses the prospects of liposomal delivery, including the specific considerations of innovation and challenges.Due to localized surface plasmon resonance (LSPR), plasmonic nanoparticles have exciting potential for improving solar photothermal conversion performance and have been extensively studied. However, in addition to enhanced solar absorption, scattering is also enhanced with the occurrence of LSPR, which is detrimental to the direct absorption of solar energy. The nanoparticles that can excite magnetic resonance can alleviate the above problem but have rarely been studied. In this work, we propose a dumbbell-type nanorod that can excite both electrical resonance and magnetic resonance. The analysis of its optical properties reveals that the dumbbell-type nanorod can excite multiple absorption peaks to enhance absorption while reducing scattering. The mechanism is the coupling between electrical resonance and magnetic resonance. Furthermore, the analysis with the slotted position of the dumbbell-type nanorod shows that the slotting should not occur at the two ends of the nanorod. It is also shown that the optical properties of the dumbbell-type nanorod can be effectively tuned by adjusting the geometric parameters of the slot. The dumbbell-type nanorods are promising for solar photothermal conversion and can be a candidate material for direct absorption solar collectors (DASCs).Leaf meristem is a cell proliferative zone present in the lateral organ primordia. In this study, we examined how cell proliferative zones in primordia of planar floral organs and polar auxin transport inhibitor (PATI)-treated leaf organs differ from those of non-treated foliage leaves of Arabidopsis thaliana, with a focus on the accumulation pattern of ANGUSTIFOLIA3 (AN3) protein, a key element for leaf meristem positioning. We found that PATI-induced leaf shape changes were correlated with cell division angle but not with meristem positioning/size or AN3 localisation. In contrast, different shapes between sepals and petals compared with foliage leaves were associated with both altered meristem position, due to altered AN3 expression patterns, and different distributions of cell division angles. A numerical simulation showed that meristem position majorly affected the final shape but biased cell division angles had a minor effect. Taken together, these results suggest that the unique shapes of different lateral organs depend on the position of the meristem in the case of floral organs and cell division angles in the case of leaf organs with different auxin flow.Exercise and dietary interventions have been described to positively affect metabolic syndrome (MetS) via molecular-induced changes. The purpose of this study was to investigate the effects of dietary carbohydrate restriction and aerobic exercise (AE) on retinol binding protein 4 (RBP4) and fatty acid binding protein 5 (FABP5) in middle-aged men with MetS. The study had a randomised, double-blinded, parallel-controlled design. Forty middle-aged men with MetS (age 53·97 ± 2·85 years, BMI = 31·09 ± 1·04 kg/m2) were randomly assigned to four groups, AE (n 10), ketogenic diet (KD; n 10), AE combined with KD (AE + KD; n 10) or control (C; n 10). RBP4, FABP5, body composition (body mass, BMI and body fat), insulin resistance, insulin sensitivity and MetS factors were evaluated prior to and after the 12-week intervention. AE + KD significantly decreased the body fat percentage (P = 0·006), BMI (P = 0·001), Zmets (P = 0·017), RBP4 (P = 0·017) and the homeostasis model of insulin resistance (HOMA-IR) (P = 0·001) as compared with control group and marginally significantly decreased the Zmets as compared with exercise group (P = 0·086). KD significantly decreased RBP4 levels as compared with control group (P = 0·041). Only the AE intervention (P = 0·045) significantly decreased FABP5 levels. Combining intervention of carbohydrate restriction with AE compared with carbohydrate restriction and AE alone improved RBP4, HOMA-IR as well as different body composition and MetS factors in middle-aged men with MetS.
