Copper (II) orthophosphate trihydrate Cu3(PO4)2·3H2O has been synthesized by the exchange chemical reactions in aqueous solutions from the compounds Cu(NO3)2·3H2O, NH4OH and H3PO4. The final product has been investigated by using atomic absorption spectroscopy (AAS), infrared spectrometry (IRS), differential thermal analysis (DTA) and X-ray powder diffraction (XRD) techniques. For the first time, the experimental heat capacity Ср° of Cu3(PO4)2·3H2O has been investigated in the temperature range 198‒402 K. Combining the experimental results with the literature data made it possible to determine the thermodynamic and thermochemical properties, such as enthalpy НТ° , entropy SТ° , Gibbs energy GТ° , enthalpy of formation ΔHf°(T), Gibbs energy of formation ΔGf°(T) and logarithm of the equilibrium constant of formation reaction log[Kf°(T)], for the title compound. It was found that at the extreme temperatures of the experiment, Cu3(PO4)2·3H2O has Ср° = 245.96 J·mol–1·K–1, Н° = –3169.59 kJ·mol–1, S° = 311.34 J·mol–1·K–1, G° = –3231.24 kJ·mol–1 (at 198 K); Ср° = 455.31 J·mol–1·K–1, Н° = –3097.93 kJ·mol–1, S° = 551.48 J·mol–1·K–1, G° = –3319.62 kJ·mol–1, ΔHf° = –3138.48 kJ·mol–1, ΔGf° = –2625.39 kJ·mol–1, log[K ] = 341.13 (at 402 K).
Philosophie pour enfants et inégalités de genre
Authors: Raïd Layla 
Published: April 2023

Cet article explore les liens étroits établis par Ann Margaret Sharp entre éthiques du care et philosophie pour enfants. Sharp mentionne rarement la variable de genre quand elle décrit les ateliers philosophiques, alors que celle-ci est déterminante pour les éthiques du care. J’explore quelques réponses à cette difficulté, qui permettent de soutenir malgré tout la position de Sharp. Cette position implique une hypothèse qui ne va pas de soi : le questionnement philosophique précoce aurait le pouvoir de contrecarrer la construction, durant l’enfance, des stéréotypes de genre.

Background:Genome-wide association studies (GWASs) have identified genetic susceptibility variants for both leukocyte telomere length (LTL) and lung cancer susceptibility. Our study aims to explore the shared genetic basis between these traits and investigate their impact on somatic environment of lung tumours.Methods:We performed genetic correlation, Mendelian randomisation (MR), and colocalisation analyses using the largest available GWASs summary statistics of LTL (N=464,716) and lung cancer (N=29,239 cases and 56,450 controls). Principal components analysis based on RNA-sequencing data was used to summarise gene expression profile in lung adenocarcinoma cases from TCGA (N=343).Results:Although there was no genome-wide genetic correlation between LTL and lung cancer risk, longer LTL conferred an increased risk of lung cancer regardless of smoking status in the MR analyses, particularly for lung adenocarcinoma. Of the 144 LTL genetic instruments, 12 colocalised with lung adenocarcinoma risk and revealed novel susceptibility loci, including MPHOSPH6, PRPF6, and POLI. The polygenic risk score for LTL was associated with a specific gene expression profile (PC2) in lung adenocarcinoma tumours. The aspect of PC2 associated with longer LTL was also associated with being female, never smokers, and earlier tumour stages. PC2 was strongly associated with cell proliferation score and genomic features related to genome stability, including copy number changes and telomerase activity.Conclusions:This study identified an association between longer genetically predicted LTL and lung cancer and sheds light on the potential molecular mechanisms related to LTL in lung adenocarcinomas.Funding:Institut National du Cancer (GeniLuc2017-1-TABAC-03-CIRC-1-TABAC17‐022), INTEGRAL/NIH (5U19CA203654-03), CRUK (C18281/A29019), and Agence Nationale pour la Recherche (ANR-10-INBS-09).
Odor descriptive ratings can predict some odor-color associations in different color features of hue or lightness
Authors: Tamura Kaori , Okamoto Tsuyoshi 
Published: April 2023

Background
Olfactory information can be associated with color information. Researchers have investigated the role of descriptive ratings of odors on odor-color associations. Research into these associations should also focus on the differences in odor types. We aimed to identify the odor descriptive ratings that can predict odor-color corresponding formation, and predict features of the associated colors from the ratings taking into consideration the differences in the odor types.

Methods
We assessed 13 types of odors and their associated colors in participants with a Japanese cultural background. The associated colors from odors in the CIE L*a*b* space were subjectively evaluated to prevent the priming effect from selecting color patches. We analyzed the data using Bayesian multilevel modeling, which included the random effects of each odor, for investigating the effect of descriptive ratings on associated colors. We investigated the effects of five descriptive ratings, namely Edibility, Arousal, Familiarity, Pleasantness, and Strength on the associated colors.

Results
The Bayesian multilevel model indicated that the odor description of Edibility was related to the reddish hues of associated colors in three odors. Edibility was related to the yellow hues of colors in the remaining five odors. The Arousal description was related to the yellowish hues in two odors. The Strength of the tested odors was generally related to the color lightness. The present analysis could contribute in investigating the influence of the olfactory descriptive rating that anticipates the associated color for each odor.

Published: April 2023

Objectives: To isolate, identify and determine the prevalence of Staphylococcus aureus among Female Patients attending Rivers State University Teaching Hospital in Port Harcourt using High Vaginal Swab samples.
Methods: A cross-sectional study was carried out on total of 103 female patients attending the outpatients department and Antenatal clinic of Rivers State University Teaching Hospital. High Vaginal Swab samples were aseptically collected from 55 non-pregnant and 48 six weeks postpartum women. These were then analysed in the Microbiology Laboratory of the Hospital, following standard microbiological procedures. Questions on age, number of sexual partners, knowledge of vaginal infection, symptomatic case, History of previous infection and treatments was responded to by each participant through the completing of questionnaires. Mannitol Salt Agar (MSA) was used for the isolation of the organism and their phenotypic traits were determined based on their cultural and biochemical characteristics.
Results: The study revealed that 25 (24.3%) consisting of 20 (36.4%) non-pregnant women and 5 (10.4%) Postpartum women were positive for Staphylococcus aureus infection. The prevalence of S. aureus among different groups was statistically significant, (P= .002). The highest percentage of S. aureus isolation (36.4%) was found in non-pregnant population. Prevalence of S. aureus was found highest 10 (18.2%) in 21-25 age group among non-pregnant women and none in 26-30 age group among postpartum women. Data obtained from the questionnaires returned showed that 10 (40%) that tested positive for the organism were asymptomatic as at the time of sample collection, had history of previous reproductive tract infection and had previously undergone treatment.
Conclusion: The high rate of vaginal Staphylococcal colonisation observed and the positive correlation between Staphylococus aureus prevalence and age, Child delivery status as well as treatment of previous reproductive tract infection seen in the study suggests the need for awareness on the importance of personal hygiene, proper antibiotic usage and regular screening of females within reproductive age.

Published: April 2023

Introduction: Coronary heart disease is the main cause of morbidity and mortality worldwide. Right ventricular (RV) infarction is often difficult to diagnose and has a poor prognosis due to rhythmic and hemodynamic complications.
Objective: The study of electrical, ultrasonographic, and coronarographic features of the VD Infarction.
Materials and Methods: Retrospective study of patients hospitalized in the Cardiology Department of the Mohammed VI University Hospital in Marrakech over a period of 24 months for MDI extended to the RV.
Results: 120 patients were hospitalized during this period for MI with extension to the VD. Atypical clinical presentation was noted in 10% of cases. Clinical examination on admission revealed signs of right heart failure in 18% of cases, including 6% complicated by cardiogenic shock. Thrombolysis was performed in 10% of the patients, 67% of them successfully. The ECG found an isolated extension to the V3R leads in 76% of the cases and in association with a V4R overshoot in 45% of the cases, conduction disorders were noted in 28% of the cases, presented essentially by first degree auriculoventricular block. Echocardiography showed impaired LV function in 82% of cases, and longitudinal systolic dysfunction of the LV in 65%. Coronary angiography was performed in 91% of the cases, half of which underwent coronary angioplasty. The combination of both CD and IVA damage was found in 40% of the cases, and damage to the middle DC was the most common in almost half of the cases. The most frequent complications were rhythmic and conductive disorders in 38% of cases, and the evolution was fatal in 8% of cases.
Conclusion: Involvement of the RV during MI is characterized by a very critical initial phase, once overcome, the overall prognosis becomes favorable in the long term.

Published: April 2023

ImportanceEmergency nurses experience high levels of workplace violence during patient interactions. Little is known about the efficacy of behavioral flags, which are notifications embedded within electronic health records (EHRs) as a tool to promote clinician safety.ObjectiveTo explore the perspectives of emergency nurses on EHR behavioral flags, workplace safety, and patient care.Design, Setting, and ParticipantsIn this qualitative study, semistructured interviews were conducted with emergency nurses at an academic, urban emergency department (ED) between February 8 and March 25, 2022. Interviews were audio recorded, transcribed, and analyzed using thematic analysis. Data analysis was performed from April 2 to 13, 2022.Main Outcomes and MeasuresThemes and subthemes of nursing perspectives on EHR behavioral flags were identified.ResultsThis study included 25 registered emergency nurses at a large academic health system, with a mean (SD) tenure of 5 (6) years in the ED. Their mean (SD) age was 33 (7) years; 19 were women (76%) and 6 were men (24%). Participants self-reported their race as Asian (3 [12%]), Black (3 [12%]), White (15 [60%]), or multiple races (2 [8%]); 3 participants (12%) self-reported their ethnicity as Hispanic or Latinx. Five themes (with subthemes) were identified: (1) benefits of flags (useful advisory; prevents violence; engenders compassion), (2) issues with flags (administrative and process issues; unhelpful; unenforceable; bias; outdated), (3) patient transparency (patient accountability; damages patient-clinician relationship), (4) system improvements (process; built environment; human resources; zero-tolerance policies), and (5) difficulties of working in the ED (harassment and abuse; unmet mental health needs of patients; COVID-19–related strain and burnout).Conclusions and RelevanceIn this qualitative study, nursing perspectives on the utility and importance of EHR behavioral flags varied. For many, flags served as an important forewarning to approach patient interactions with more caution or use safety skills. However, nurses were skeptical of the ability of flags to prevent violence from occurring and noted concern for the unintended consequences of introducing bias into patient care. These findings suggest that changes to the deployment and utilization of flags, in concert with other safety interventions, are needed to create a safer work environment and mitigate bias.

ImportanceTimely initiation of postoperative radiation therapy (PORT) is associated with reduced recurrence rates and improved overall survival in patients with head and neck squamous cell carcinoma (HNSCC). Measurement of the association of social-ecological variables with PORT delays is lacking.ObjectiveTo assess individual and community-level factors associated with PORT delay among patients with HNSCC.Design, Setting, and ParticipantsThis prospective cohort study carried out between September 2018 and June 2022 included adults with untreated HNSCC who were enrolled in a prospective registry at a single academic tertiary medical center. Demographic information and validated self-reported measures of health literacy were obtained at baseline visits. Clinical data were recorded, and participant addresses were used to calculate the area deprivation index (ADI), a measure of community-level social vulnerability. Participants receiving primary surgery and PORT were analyzed. Univariable and multivariable regression analysis was performed to identify risk factors for PORT delays.ExposuresSurgical treatment and PORT.Main Outcomes and MeasuresThe primary outcome was PORT initiation delay (&amp;gt;42 days from surgery). Risk of PORT initiation delay was evaluated using individual-level (demographic, health literacy, and clinical data) and community-level information (ADI and rural-urban continuum codes).ResultsOf 171 patients, 104 patients (60.8%) had PORT delays. Mean (SD) age of participants was 61.0 (11.2) years, 161 were White (94.2%), and 105 were men (61.4%). Insurance was employer-based or public among 65 (38.5%) and 75 (44.4%) participants, respectively. Mean (SD) ADI (national percentile) was 60.2 (24.4), and 71 (41.8%) resided in rural communities. Tumor sites were most commonly oral cavity (123 [71.9%]), with 108 (63.5%) classified as stage 4 at presentation. On multivariable analysis, a model incorporating individual-level factors with health literacy in addition to community-level factors was most predictive of PORT delay (AOC= 0.78; R2, 0.18).Conclusions and RelevanceThis cohort study provides a more comprehensive assessment of predictors of PORT delays that include health literacy and community-level measures. Predictive models that incorporate multilevel measures outperform models with individual-level factors alone and may guide precise interventions to decrease PORT delay for at-risk patients with HNSCC.
The Readiness of Water Molecules to Split into Hydrogen + Oxygen: A Proposed New Aspect of Water Splitting

Published: April 2023

AbstractThe potential of the anode, at which the evolution of oxygen begins, is a key parameter that describes how well water is split in water electrolyzers. Research efforts related to electrocatalytically initiated water splitting that aim at reducing the oxygen evolution reaction (OER) overpotential to date focus on the optimization of materials used to produce the electrodes. Descriptors for the readiness of the H2O molecule itself to break down into its components have not been considered in water electrolysis experiments so far. In a simple set of experiments, it is found that adding dioxane to aqueous solutions leads to a substantial blueshift of the frequency of the OH stretch vibration which is a sign of an increased strength of the OH bond (intramolecular bonding). This phenomenon coincides with a significant increase in the OER onset potential as derived from cyclic voltammetry experiments. Thus, the OH stretch frequency can be an ideal indicator for the readiness of water molecules to be split in its cleavage products. This is thought to be first example of a study into the relationship between structural features of water as derived from Fourier transform infrared (FTIR) spectroscopic studies and key results derived from water electrolysis experiments.

Published: April 2023

AbstractSurface chemistry and quantum confinement in nanocrystals (NCs) can modulate the energy transfer efficiency between lead halide perovskite (LHP) NCs and acceptor molecules in hybrid assemblies. It is demonstrated here that colloidal CsPbBr3 NCs capped with the oleic acid/oleylamine ligand pair act as a good singlet sensitizer of meso‐(4‐carboxyphenyl) BODIPY dye (C‐BPY). The energy transfer efficiency of ≈85% at 1 × 10−6 m is consistent with the strong binding of the BODIPY to the NC surface via the carboxylate group, as is evidenced by nuclear magnetic resonance (NMR) and Fourier‐transform infrared (FTIR) spectroscopies. A thorough analysis suggests a Förster resonance energy transfer (FRET) mechanism from the perovskite to the acceptor dye. These results provide a better understanding of the underlying interaction in perovskite−organic chromophore nanohybrids and can be employed in the design of novel harvesting assemblies.
Coacervate‐Enhanced Deposition of Sprayed Pesticide on Hydrophobic/Superhydrophobic Abaxial Leaf Surfaces

Published: April 2023

AbstractDeposition of high‐speed droplets on inverted surfaces is important to many fundamental scientific principles and technological applications. For example, in pesticide spraying to target pests and diseases emerging on abaxial side of leaves, the downward rebound and gravity of the droplets make the deposition exceedingly difficult on hydrophobic/superhydrophobic leaf underside, causing serious pesticide waste and environmental pollution. Here, a series of bile salt/cationic surfactant coacervates are developed to attain efficient deposition on the inverted surfaces of diverse hydrophobic/superhydrophobic characteristics. The coacervates have abundant nanoscale hydrophilic/hydrophobic domains and intrinsic network‐like microstructures, which endow them with efficient encapsulation of various solutes and strong adhesion to surface micro/nanostructures. Thus, the coacervates with low viscosity achieve high‐efficient deposition on superhydrophobic abaxial‐side of tomato leaves and inverted artificial surfaces with a water contact angle from 170° to 124°, much better than that of commercial agricultural adjuvants. Intriguingly, the compactness of network‐like structures dominantly controls adhesion force and deposition efficiency, and the most crowded one leads to the most efficient deposition. The tunable coacervates can help comprehensively understand the complex dynamic deposition, and provide innovative carriers for depositing sprayed pesticides on abaxial and adaxial sides of leaves, thereby potentially reducing pesticide use and promoting sustainable agriculture.

Published: April 2023

AbstractNa0.44MnO2 is a promising cathode material for sodium‐ion batteries owing to its excellent cycling stability and low cost. However, insufficient sodium storage sites still hinder its practical applications. Herein, a facile strategy to induce the efficient structural transformation from the tunnel to the layered type of Na0.44MnO2 by trace W‐doping for the first time is reported. The W‐doping not only enriches the sodium storage sites but also improves the cycling performance. As a result, the phase‐pure P2‐Na0.44Mn0.99W0.01O2 demonstrates an enhanced reversible specific capacity of 195.5 mAh g−1 and energy density of 517 Wh kg−1 at 0.1 C, accompanying superior cycling stability with capacity retention of 80% over 200 cycles. Moreover, the W‐doped samples show high structure stability in a moist atmosphere and can still maintain the original electrochemical performance after water treatment. In situ and ex situ characterizations reveal the enhanced structural stability of the P2‐Na0.44Mn0.99W0.01O2 electrodes. This work provides a facile strategy on the structural engineering of transition metal oxides to induce the tunnel‐to‐layered structure transformation and could shed light on the design and construction of stable and high‐capacity cathode materials.

AbstractIntroductionThe mRNA‐based vaccine was released as a COVID‐19 prophylactic; however, its efficacy in organ transplant recipients is unknown. This study aimed to clarify this in liver transplant recipients.MethodsHerein, liver transplant recipients from two hospitals who received vaccines were included. Immunoglobulin‐G antibodies against the spike and nucleocapsid proteins were measured chronologically after the second, third, and fourth vaccine doses.ResultsAntibody levels in 125 liver transplant recipients and 20 healthy volunteers were analyzed. The median age at transplant was 35 (interquartile range 1, 53) years, and the period between transplant and the first dose was 15.2 ± 7.7 years. After the second and third doses, 89.1% and 100% of recipients displayed a positive humoral response, respectively. Anti‐spike antibodies after the second dose were significantly reduced at 3 and 6 months, compared to that at 1 month (26.0 [5.4, 59.5], 14.7 [6.5, 31.4] vs. 59.7 [18.3, 164.0] AU/mL, respectively, p < 0.0001). However, a booster vaccine significantly elevated anti‐spike antibodies in LT recipients (p < 0.0001) as well as in healthy controls (p < 0.0001). Additionally, the decay rate was comparable between the transplant recipients and controls (2.1 [0.8, 4.5] vs. 2.7 [1.1, 4.1] AU/mL/day, p = 0.9359). Only 4.0% of vaccinated transplant recipients were positive for anti‐nucleocapsid antibodies.ConclusionLiver transplant recipients can acquire immunity similar to that of healthy people through vaccination against SARS‐CoV‐2. The antibody decay rate is the same, and booster vaccinations should be administered similarly to that in healthy individuals.
