A field experiment was conducted to study the effect of different organic manures and their levels on nutrient status and soil microbial activity in rose at Hisar during 2020-21. The treatments comprised of 3 different types of organic manures viz., farm yard manures, vermicompost and poultry manure and 4 levels control, 4 kg/m2, 5 kg/m2 and 6 kg/m2. The experiment was carried out in the split plot design with three replications. Observation on organic carbon, dehydrogenase activity and alkaline phosphatase activity, N, P and K content in rose leaves and available N, P and K content in soil at the time of harvest were recorded. Organic carbon in soil was maximum (0.93%) with the application of vermicompost while dehydrogenase and alkaline phosphatase activity were highest with the application of farmyard manure and poultry manure, respectively. Nitrogen (2.17%) and phosphorus (0.27%) content were maximum in rose leaves at harvest stage with the application of poultry manure while Potassium (1.41%) content was maximum vermicompost. Same trend was observed in the nutrient status of soil with the application of different organic manures. It is concluded that the application of poultry manures had pronounced effect on microbial activity and nutrient status in rose.

Background: Hysterosalpingography is an investigative modality used in the evaluation of the uterine cavity, fallopian tubes, and adjacent peritoneal cavity following the injection of contrast material through the cervical canal.
Objective: To determine the relationship between abnormal cervical findings and abnormal results at hysterosalpingography in infertile women.
Materials and Methods: This descriptive, cross-sectional study conducted at the Obstetrics and Gynaecology, and Radiology Departments of four health institutions in Bayelsa State, Nigeria, between June and December, 2022. Hysterosalpingography was done for 332 infertile women, after obtaining written informed consent. Data were entered into a pre-designed proforma, and analysed using Statistical Product and Service Solutions (SPSS) version 25.0. Results were presented in frequencies and percentages for categorical variables, and mean and standard deviation for continuous variables.
Results: Cervical finding was normal in only 49.7% (n=165) of the participants undergoing HSG. The abnormal cervical findings include deformed (27.7%), hyperaemic (5.7%), dull (5.7%), hard (5.7%) and short (5.4%) cervix. There was a statistically significant relationship between abnormal cervical findings during HSG and tubal blockade (ꭓ2 = 196.7; p – 0.001), presence of salpingitis (ꭓ2 = 41.1; p – 0.001), peritubal adhesion (ꭓ2 = 19.9; p – 0.001) and intrauterine adhesion (ꭓ2 = 35.62; p – 0.001).
Conclusion: Intrauterine adhesion, salpingitis, tubal blockade and peritubal adhesion on HSG is associated with some abnormal cervical findings in about half of infertile women in this study. The same pathological processes responsible for injury to the upper genital tract and tubal infertility may have caused injury to the cervix in the group of women.

ImportanceAntibiotics are an important risk for Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN), which are the most severe types of drug hypersensitivity reaction with a mortality rate up to 50%. To our knowledge, no global systematic review has described antibiotic-associated SJS/TEN.ObjectiveTo evaluate the prevalence of antibiotics associated with SJS/TEN worldwide.Data SourcesThe MEDLINE and Embase databases were searched for experimental and observational studies that described SJS/TEN risks since database inception to February 22, 2022.Study SelectionIncluded studies adequately described SJS/TEN origins and specified the antibiotics associated with SJS/TEN.Data Extraction and SynthesisTwo reviewers (E.Y.L. and C.K.) independently selected the studies, extracted the data, and assessed the risk of bias. A meta-analysis using a random-effects model was performed in the studies that described patient-level associations. Subgroup analyses were performed to explore the heterogeneity. The risk of bias was assessed using the Joanna Briggs Institute checklist, and the certainty of evidence was rated using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach.Main Outcomes and MeasuresPrevalence of antibiotic-associated SJS/TEN was presented as pooled proportions with 95% CIs.ResultsAmong the 64 studies included in the systematic review, there were 38 studies that described patient-level associations; the meta-analysis included these 38 studies with 2917 patients to determine the prevalence of single antibiotics associated with SJS/TEN. The pooled proportion of antibiotics associated with SJS/TEN was 28% (95% CI, 24%-33%), with moderate certainty of evidence. Among antibiotic-associated SJS/TEN, the sulfonamide class was associated with 32% (95% CI, 22%-44%) of cases, followed by penicillins (22%; 95% CI, 17%-28%), cephalosporins (11%; 95% CI, 6%-17%), fluoroquinolones (4%; 95% CI, 1%-7%), and macrolides (2%; 95% CI, 1%-5%). There was a statistically significant heterogeneity in the meta-analysis, which could be partially explained in the subgroup analysis by continents. The overall risk of bias was low using the Joanna Briggs Institute checklist for case series.Conclusion and RelevanceIn this systematic review and meta-analysis of all case series, antibiotics were associated with more than one-quarter of SJS/TEN cases described worldwide, and sulfonamide antibiotics remained the most important association. These findings highlight the importance of antibiotic stewardship, clinician education and awareness, and weighing the risk-benefit assessment of antibiotic choice and duration.

AbstractCOVID‐19 pandemic outbreak poses a great threat to human health. Face masks have been considered as important personal protective equipment to prevent the COVID‐19 transmission. However, pathogens can survive up to several days on the fabrics of commercial masks, which increases the risk of direct/indirect microbial transmission. Herein, new cationic conjugated microporous polymers (CCMPs)‐based coating is developed, which possesses extended π‐conjugated skeletons and massive quaternary ammonium salt (QAS) groups, exhibiting dual‐modal antimicrobial inactivation, including sunlight‐driven photodynamic sterilization through the generation of reactive oxygen species and contact sterilization through QAS groups. As a result, the CCMPs coatings can rapidly and efficiently eradicate 99% of model microbes, such as Escherichia coli and Staphylococcus aureus under solar illumination, and also ensure the great antimicrobial effect in the absence of light. More importantly, the CCMPs coatings exhibit excellent durability, reusability as well as antimicrobial stability in humid environment. Contributing to the outstanding processability and formability, CCMPs can be in situ synthesized and coated over fibers through a simple spray procedure. Taken together, the design provides a promising strategy for developing reusable and self‐sterilizing antimicrobial fabrics, particularly for the application of face masks to tackle infectious pathogen and viruses in daily protection and medical applications.

AbstractQuasi‐2D perovskite light‐emitting diodes (PeLEDs) are promising candidates to realize superior luminescent. However, the poorly controlled phase distribution and surface defects hinder the improvement of the device's performance. Here, by introducing rubidium bromide (RbBr) to tune the crystallization kinetics of quasi‐2D perovskites, more uniform phase distribution is achieved through the suppression of medium‐n phases, resulting in narrower emission spectrum and more efficient energy transfer. Meanwhile, the defects are effectively passivated by the addition of RbBr. As a result, the photoluminescence quantum yield (PLQY) of quasi‐2D perovskite films increases significantly from 45.6% to 81.3%, and the maximum external quantum efficiency (EQE) of PeLEDs reaches 18.92%. This finding provides a new insight into the phase distribution control of quasi‐2D perovskites and the further improvement of PeLEDs.

Abstract2D ferroelectrics provide great promise for future electronics owing to their unique properties at 2D limit. Although simple perovskite oxides (such as BaTiO3 and PbTiO3) are an important target for 2D ferroelectrics, controlled synthesis of 2D nanosheets still remains a challenge. Here, this issue is addressed by using a new chemical protocol; unilamellar Ti0.87O2 nanosheets can serve as templates, guiding the solvothermal synthesis of 2D BaTiO3 nanosheets with a molecularly thin thickness (< 3 nm). Raman spectroscopy, second‐harmonic generation, and transmission electron microscopy characterizations suggest the formation of tetragonal ferroelectric BaTiO3 nanosheets. Based on piezoresponse force microscopy, BaTiO3 nanosheets exhibit a clear ferroelectric response with a high Curie temperature (≈100 °C) even down to 1.8 nm thickness. This study provides new opportunities to investigate perovskite ferroelectrics with the critical thickness.
Tailoring the d‐Band Center over Isomorphism Pyrite Catalyst for Optimized Intrinsic Affinity to Intermediates in Lithium–Oxygen Batteries
Authors: Li Deyuan , Zhao Lanling , Wang Jun , Yang Chunpeng 
Published: February 2023

AbstractRechargeable lithium–oxygen batteries (LOBs) are regarded as one of the most promising candidates for the next generation of energy storage devices. Nevertheless, the lack of understanding of the relationships between structure, property, and performance of catalysts limits the rational development of efficient cathode catalysts, and therefore, hinders the commercial application of LOBs. Herein, a d‐band center regulation strategy is proposed to construct an isomorphism composite of NiS2‐CoS2@nitrogen‐doped carbon (NiS2‐CoS2@NC) as an advanced cathode catalyst for boosting the electrocatalytic activities of LOBs. Density functional theory calculations reveal that the introduction of Ni atoms not only redistributes the internal charges on the isomorphism structure but also modulates the adsorption capacities of the intermediates by tuning the d‐band center, thus promoting oxygen reduction reaction/oxygen evolution reaction kinetics and reducing the reaction overpotentials. As expected, NiS2‐CoS2@NC catalyzed LOBs present superior electrochemical performance including large initial discharge/charge specific capacity of 14 551/13 563 mAh g−1, an ultralong cycle life over 490 cycles at a current density of 500 mA g−1, and excellent rate performance. The insight into the regulation of the adsorption capacity of the catalyst by tailoring its d‐band center facilitates the rational construction of efficient electrocatalysts for LOBs and other electrocatalytic systems.

AbstractPossible routes for intra‐cluster bond formation (ICBF) in protonated serine dimers have been studied. We found no evidence of ICBF following low energy collision‐induced dissociation (in correspondence with previous works), however, we do observe clear evidence for ICBF following photon absorption in the 4.6–14 eV range. Moreover, the comparison of photon‐induced dissociation measurements of the protonated serine dimer to those of a protonated serine dipeptide provides evidence that ICBF, in this case, involves peptide bond formation (PBF). The experimental results are supported by ab initio molecular dynamics and exploration of several excited state potential energy surfaces, unraveling a pathway for PBF following photon absorption. The combination of experiments and theory provides insight into the PBF mechanisms in clusters of amino acids, and reveals the importance of electronic excited states reached upon UV/VUV light excitation.

AbstractHigh‐voltage lithium metal batteries (LMBs) pose severe challenges for the matching of electrolytes with aggressive electrodes, especially at low temperatures. Here, we report a rational modification of the Li+solvation structure to extend the voltage and temperature operating ranges of conventional electrolytes. Ion‐ion and ion‐dipole interactions as well as the electrochemical window of solvents were tailored to improve oxidation stability and de‐solvation kinetics of the electrolyte. Meanwhile, robust and elastic B and F‐rich interphases are formed on both electrodes. Such optimization enables Li||LiNi0.5Mn1.5O4cells (90.2 % retention after 400 cycles) and Li||LiNi0.6Co0.2Mn0.2O2(NCM622) cells (74.0 % retention after 200 cycles) to cycle stably at an ultra‐high voltage of 4.9 V. Moreover, NCM622 cells deliver a considerable capacity of 143.5 mAh g−1at −20 °C, showing great potential for practical uses. The proposed strategy sheds light on further optimization for high‐voltage LMBs.

AbstractBackgroundAlterations within large‐scale brain networks—namely, the default mode (DMN) and salience networks (SN)—are present among individuals with posttraumatic stress disorder (PTSD). Previous real‐time functional magnetic resonance imaging (fMRI) and electroencephalography neurofeedback studies suggest that regulating posterior cingulate cortex (PCC; the primary hub of the posterior DMN) activity may reduce PTSD symptoms and recalibrate altered network dynamics. However, PCC connectivity to the DMN and SN during PCC‐targeted fMRI neurofeedback remains unexamined and may help to elucidate neurophysiological mechanisms through which these symptom improvements may occur.MethodsUsing a trauma/emotion provocation paradigm, we investigated psychophysiological interactions over a single session of neurofeedback among PTSD (n = 14) and healthy control (n = 15) participants. We compared PCC functional connectivity between regulate (in which participants downregulated PCC activity) and view (in which participants did not exert regulatory control) conditions across the whole‐brain as well as in a priori specified regions‐of‐interest.ResultsDuring regulate as compared to view conditions, only the PTSD group showed significant PCC connectivity with anterior DMN (dmPFC, vmPFC) and SN (posterior insula) regions, whereas both groups displayed PCC connectivity with other posterior DMN areas (precuneus/cuneus). Additionally, as compared with controls, the PTSD group showed significantly greater PCC connectivity with the SN (amygdala) during regulate as compared to view conditions. Moreover, linear regression analyses revealed that during regulate as compared to view conditions, PCC connectivity to DMN and SN regions was positively correlated to psychiatric symptoms across all participants.ConclusionIn summary, observations of PCC connectivity to the DMN and SN provide emerging evidence of neural mechanisms underlying PCC‐targeted fMRI neurofeedback among individuals with PTSD. This supports the use of PCC‐targeted neurofeedback as a means by which to recalibrate PTSD‐associated alterations in neural connectivity within the DMN and SN, which together, may help to facilitate improved emotion regulation abilities in PTSD.

AbstractRheum tanguticum (Rh. tanguticum) is a Chinese medicinal plant traditionally used in the treatment of constipation. As a byproduct, the seeds of this plant are rich in nutrients and phytochemicals. This study aimed to determine and assess seed germination ability, seed physical characteristics, soluble protein content, chemical constituents and antioxidant capacity from different breeding lines, to promote the development and utilization of seed resources. Significant differences were observed for the soluble protein content and antioxidant assays among the ten lines. The contents of aloe‐emodin, rhein and catechins accumulated in seeds were extremely low and significantly different from those in roots. In contrast, emodin and chrysophanol were abundant in seeds, and significant differences were observed between seeds and roots. It was found that associations between gallic acid and catechins were not significant for either soluble protein or antioxidant capacity. There was a significantly positive correlation between the contents of four anthraquinones (aloe‐emodin, rhein, emodin and chrysophanol) and soluble protein. Seeds have potent antioxidative capacity and relatively high levels of soluble protein content. The rich chemical composition of seeds can be widely used in the medical industry for further development.

Published: February 2023

AbstractDehydrogenation of glycerol for CO2 reduction can simultaneously produce lactic acid (LA) and formic acid (FA) products with high added value, greatly improving the atomic economy and the actual benefits. We report that Ru‐MACHO (regR) as a catalyst can satisfy the requirements of parallel reaction at the same time. The designed experiment confirms that under the conditions of 200 °C and 48 h, 3 mg Ru‐MACHO (regR) catalyst can obtain FA and LA yields of 40 % and 45 %, respectively. The possible reaction path of glycerol dehydrogenation for CO2 reduction is confirmed by the isotopic tracer technique and nuclear magnetic resonance analysis.
Co2+ to Al3+ Substitution Induced Dual‐Site Synergistic Catalysis to Friedel‐Crafts Alkylation Reactions
Authors: Yang Yao , Sun Yurong , Gao Wenliang , Yang Tao 
Published: February 2023

AbstractThe dual‐site synergistic effect in heterogeneous catalysis is quite interesting, and also complex because at least two substrate molecules are adsorbed or activated on the catalyst surface, which apparently needs two spatially separated and functionally independent active sites. It would become more difficult when the substrate molecules are large ones. The replacement of Al3+ in Al4B6O15 lattice with Co2+ leads to the formation of unsaturated Co2+ (4‐fold coordination) along with oxygen vacancies (Ov). The former one behaves as a medium‐strength Lewis acid site, and can adsorb and activate molecules with a nitro group (e. g., β‐nitrostyrene). The latter one can adsorb and activate oxygen species, which further activates the indole derivatives. Next, the spatially separated dual sites on the catalyst surface can synergistically and efficiently catalyze their Friedel‐Crafts alkylation reactions under mild conditions. The high durability can be proved by the as‐maintained high yields, that is, 98, 93, 96, 92 and 90 % for 5 runs, respectively. The reaction kinetics obey the second‐order characteristic. Annealing under hydrogen condition can further generate more surficial Ov, leading to an improvement to the catalytic activity. A simple and probably routine aliovalent doping endows such a complex synergistic catalysis involving two large substrate molecules, providing an inspired perspective of developing dual‐site catalysts.
