The aim of this case report is to draw attention at the potential severity of presentation of these associated pathologies. Prevention through early screening of colorectal cancer in patients with coronary artery disease and vice versa is the guarantee of a better management of the two pathologies. Cardiovascular disease and cancer are the two leading causes of death worldwide. Emerging evidence suggests associations between cardiovascular disease and several cancers, including colorectal cancer. Many cases have reported severe coronary artery disease (CAD) in association with colorectal cancer including triple vessel disease. To the best of our knowledge this is the first case reporting a total occlusion of the left main coronary artery in such patients.
We report the case of a 52 years old woman presented to our cath lab for severe angina (Class III of the Canadian classification) and impairment of left ventricle function. Six months before the patient was diagnosed with a metastatic colorectal cancer. Coronary angiography showed absence of anterograde opacification of the left coronary system. Selective right coronary artery angiography showed a retrograde filling of the left coronary system by collaterals issued from proximal and distal dominant right coronary artery.
Several studies have reported the association between colorectal neoplasm and CAD but Isolated left main coronary artery disease is extremely uncommon. Patients with left main coronary artery disease have always a grim prognosis and without prompt revascularization 60% will die after 5 years while survivors live with severe angina; heart failure or both.

The development of rice genotypes with impressive tolerance to abiotic stress is one of the primary objectives of rice breeding programs. The current study was carried out to assess the capability of different indices to identify rice genotypes that are drought-tolerant under Egyptian conditions during the two growing seasons 2018 and 2019. Thirteen drought tolerance indices were calculated using the grain yield of twenty rice genotypes. According to the combined analysis of variance for grain yield, there were highly significant differences between genotypes (G), irrigation regimes (I), and their interactions. All drought tolerance indices, as well as grain yields under non-stress and stress conditions (Yp and Ys), exhibited significant variations among genotypes. For Yp, Ys, and all indices assessed, estimates of broad sense heritability (h2) and genetic advance as a percentage of mean (GAM%) were high. Using mean performances, drought tolerance indices, and multivariate analysis, the genotypes Giza 179, Sakha 104, IET 1444, and GZ 6296-12-1-2-1 were superior genotypes under both stress and non-stress conditions, as were the genotypes Sakha 107, IRAT 170, IR 68552-55-3-2, WAB 56-104, IRGA 318-11-6-2-6, and NERICA -4 under stress conditions. Hence, it was suggested that they can be utilized as parents in hybridization programs that aim to improve the drought tolerance of other rice genotypes in Egypt. Furthermore, mean productivity index (MP), geometric mean productivity (GMP), stress tolerance index (STI), harmonic mean (HM), and yield index (YI) were the tolerance indices that can be classified as better predictors of drought tolerance considering the yield potentials of the genotypes.

Aims: This study aims to present a comprehensive analysis of bioleaching, the fundamental idea behind it, the emergence of microbes and the bioleaching approaches.
Study Design: To do this, this research has been developed on a foundation of significant topics. The researcher used a quantitative approach in this particular investigation. The quantitative study is presented in tables that list the bioleaching processes and efficient microorganisms.
Place and Duration of Study: This study was carried out in Chemical Engineering department, Delta State University of Science and Technology, Ozoro, Nigeria.
Methodology: The researcher decided on a combination methodology because of the context of the present investigation. The approach of data collection and analysis employing qualitative as well as quantitative methodologies is known as combined research design.
Results: The lengthy training period of microorganisms at the laboratory scale, which is significantly impacted by other experimental variables, is one of the key difficulties faced by the bioleaching process. Therefore, the key to increasing the simplicity of bioleaching technologies in large-scale industrial production is to enhance the bioleaching microorganism’s currently in use so that they can continue to be highly active under more complicated reaction conditions. Regarding the microbial problem, biological leaching piles of just a few genes in the offspring of acidophilic microorganisms have been documented. Although some bacterial genomes from acid mine drainage and acidic environments have been used to create replacements, these models cannot fully depict the potential for leaching; in addition, it can be difficult for researchers to obtain samples of microbes from actual production, making further research challenging.
Conclusion: In the years to come, microbial use for waste treatment and mineral processing will continue to gain importance on a global scale. The need to process ores with trace amounts of copper and gold, the potential for recycling waste spoils and tailings, financial limitations, and potential legislative changes on the environmental impact of more conventional approaches like hydrometallurgy will all contribute to this. The employment of chemolithotrophic and heterotrophic bacteria will be a significant addition, boosting the leaching rates and metal recoveries and enabling the treatment of resistant ores like chalcopyrite.

ImportanceResiding in a low-income neighborhood is generally associated with worse pregnancy outcomes. It is not known if moving from a low- to higher-income area between 2 pregnancies alters the risk of adverse birth outcomes in the subsequent birth compared with women who remain in low-income areas for both births.ObjectiveTo compare the risk of adverse maternal and newborn outcomes among women who achieved upward area-level income mobility vs those who did not.Design, Setting, and ParticipantsThis population-based cohort study was completed in Ontario, Canada, from 2002 to 2019, where there is universal health care. Included were all nulliparous women with a first-time singleton birth at 20 to 42 weeks’ gestation, each residing in a low-income urban neighborhood at the time of the first birth. All women were then assessed at their second birth. Statistical analysis was conducted from August 2022 to April 2023.ExposureMovement from a lowest-income quintile (Q1) neighborhood to any higher-income quintile neighborhood (Q2-Q5) between the first and second birth.Main Outcomes and MeasuresThe maternal outcome was severe maternal morbidity or mortality (SMM-M) at the second birth hospitalization or up to 42 days post partum. The primary perinatal outcome was severe neonatal morbidity or mortality (SNM-M) within 27 days of the second birth. Relative risks (aRR) and absolute risk differences (aARD) were estimated by adjusting for maternal and infant characteristics.ResultsA total of 42 208 (44.1%) women (mean [SD] age at second birth, 30.0 [5.2] years) experienced upward area-level income mobility, and 53 409 (55.9%) women (age at second birth, 29.0 [5.4] years) remained in income Q1 between births. Relative to women who remained in income Q1 between births, those with upward mobility had a lower associated risk of SMM-M (12.0 vs 13.3 per 1000 births), with an aRR of 0.86 (95% CI, 0.78 to 0.93) and aARD of −2.09 per 1000 (95% CI, −3.1 to −0.9 per 1000 ). Likewise, their newborns experienced lower respective rates of SNM-M (48.0 vs 50.9 per 1000 live births), with an aRR of 0.91 (95% CI, 0.87 to 0.95) and aARD of −4.7 per 1000 (95% CI, −6.8 to −2.6 per 1000).Conclusions and RelevanceIn this cohort study of nulliparous women living in low-income areas, those who moved to a higher-income area between births experienced less morbidity and death in their second pregnancy, as did their newborns, compared with those who remained in low-income areas between births. Research is needed to determine whether financial incentives or enhancement of neighborhood factors can reduce adverse maternal and perinatal outcomes.

Abstract

Objectives
We examined the associations of perceived psychosocial safety climate (PSC) with psychological distress and work engagement in Japanese employees. We also examined the mediation effects of job demands (i.e., psychological demands) and job resources (i.e., job control, worksite support, and extrinsic reward) in these associations.

Methods
A total of 2200 employees (1100 men and 1100 women) registered with a Japanese online survey company were surveyed using a self-administered web-based questionnaire containing the scales on PSC (12-item PSC scale), job demands and job resources (Job Content Questionnaire and Effort-Reward Imbalance Questionnaire), psychological distress (K6 scale), and work engagement (9-item Utrecht Work Engagement Scale), and items on demographic and occupational characteristics (i.e., age, sex, education, occupation, work form, and working hours per week). A multiple mediation analysis with a bootstrap method was conducted.

Results
After adjusting for demographic and occupational characteristics, significant negative and positive total effects of perceived PSC were observed on psychological distress and work engagement, respectively (c = −0.258 [95% confidence interval (CI): −0.298 to −0.219] and 0.383 [95% CI: 0.344–0.421], respectively). When we included job demands and job resources as mediators in the model, significant total mediation effects in these associations were observed (c − c′ = −0.181 [95% CI: −0.221 to −0.143] and 0.269 [95% CI: 0.234–0.304], respectively).

Conclusions
Our findings suggest that perceived PSC is negatively associated with psychological distress and positively associated with work engagement, and that these associations are partially mediated (or explained) by job demands and job resources.
Pull‐out strength of perforated steel plates with oval‐shaped perforation
Authors: Fujinaga Takashi , Tanaka Teruhisa 
Published: May 2023

AbstractThe use of Perfobond Leisten (PBL) shear connectors in building structures has attracted increasing interest. A new approach for using perforated steel plates in concrete‐filled steel tube (CFST) column splices was implemented in this study. The shape of the perforation opening in perforated steel plates is generally a circle, similar to that of PBL shear connectors. However, in this study, an oval‐shaped perforation was used to increase the double shear area of the concrete. A pull‐out experiment was conducted on perforated steel plates with oval‐shaped perforations in a CFST block to evaluate the tensile performance of the perforated steel plates. A total of 29 specimens were tested, and the pull‐out strengths of the perforated steel plates were determined and analyzed under passive confinement from the steel tube. The contribution of the stress transfer was discussed in terms of the double shear of the concrete in the perforation and the bond and/or friction between the surface of the steel plate and concrete. Formulas for determining the maximum pull‐out strength were also developed.

Abstract

Agri‐environment schemes (AES) incentivise land‐management practices aimed at mitigating environmental impacts. However, their effectiveness depends on the duration and type of management. We modelled the potential for grassland AES options in Wales (UK) to achieve positive changes in plant diversity via change in soil conditions.

We modelled the response of plants and soils to the predicted effects of AES options over a 13‐year time interval. We applied scenarios of change in soil conditions in three managed grassland types, using high‐resolution baseline soil and vegetation data collected in grasslands across Wales, UK. We also applied scenarios of climate change to determine the extent to which this might modify the impact of AES intervention on plant species compositional turnover.

Empirical models of soil response to extensification were constructed from published experimental data and used to drive change in soil inputs to a small ensemble of ecological niche models for British plants. These models were applied to the local pool of species in each baseline (2 × 2 m) quadrat plus a wider 10 × 10 km pool from which we draw species absent at baseline but predicted to find conditions suitable as a result of AES intervention and climate change, thus estimating dark diversity at each location. Outputs were summarised by grouping species by the ecosystem functions and services they support and by matching projected species composition to the UK National Vegetation Classification.

Scenario modelling indicated that at least 10 years of management under grassland AES options were needed to achieve conditions suitable for desirable plant assemblages more typical of lower fertility habitats.

Synthesis and applications: We predict that management effects will have a more marked effect on vegetation and soil than predicted climate variation up to 2029. Realising modelled changes in habitat suitability as species compositional turnover and community assembly is likely to require additional measures to assist plant dispersal and establishment.
Flickering presentations do affect the judgment of learning but not the learning outcome
Authors: Ebersbach Mirjam , Guschlbauer Jana Antonia , Rummer Ralf 
Published: May 2023

AbstractWe examined whether visual disfluency, as elicited by presenting text on flickering slides, affects learning positively and the global judgment of learning (JOL) negatively. Participants (N = 202 in Experiment 1, between‐subjects design; N = 53 in Experiment 2, within‐subjects design) saw in an online session multiple slides including textual information that they had to learn. The slides were presented either fluently or disfluently, that is, interrupted by rapid presentations of black slides, evoking a flickering effect. Thus, instead of manipulating the textual material (e.g., by using different fonts), as most studies on the disfluency effect so far did, we manipulated the characteristics of the presentation (i.e., flickering vs. nonflickering). In both experiments, JOL was lower in the flickering than in the nonflickering condition. However, flickering slides did not lead to a better memory performance. The results provide further evidence for the assumption that a beneficial disfluency effect is questionable.

Published: May 2023

AbstractTransition‐metal based layered doubled hydroxides (LDH) as oxygen evolution reaction (OER) catalysts have attracted tremendous research interests. However, it is still a great challenge to strengthen the intrinsic activity of LDH. Herein, hollow CoNiFe‐LDH nanocages with amorphous/crystal phase and element gradient distribution are successfully constructed through the coordinated etching and precipitation process. Utilizing the difference of solubility product constants among transition metal cations to generate the gradient distribution effect in nanocages is proposed for the first time. The distinctive element gradient distribution in hollow CoNiFe‐LDH nanocages results in the composition gradient, which can provide the heterojunctions effect and play an important role in regulating morphology and electronic structure. Density functional theory calculations disclose that the synergistic effect between elements significantly regulates the electron density and enhances the conductivity. When employed as OER electrocatalysts, it exhibits a very competitive overpotential of 257 mV at 10 mA cm−2 combined with a low Tafel slope of 31.4 mV dec−1. This work represents a promising strategy to fabricate highly efficient OER catalysts for electrochemical water splitting and provides new opportunities to understand the promotion mechanism of intrinsic activity.

Published: May 2023

AbstractHigh performance flexible batteries are essential ingredients for flexible devices. However, general isolated flexible batteries face critical challenges in developing multifunctional embodied energy systems, owing to the lack of integrative design. Herein, inspired by scales in creatures, overlapping flexible lithium‐ion batteries (FLIBs) consisting of energy storage scales and connections using LiNi0.5Co0.2Mn0.3O2 (NCM523) and graphite electrodes are presented. The scale‐dermis structure ensures a high energy density of 374.4 Wh L−1 as well as a high capacity retention of 93.2% after 200 charge/discharge cycles and 40 000 bending times. A variable stiffness property is revealed that can be controlled by battery configurations and deformation modes. Furthermore, the overlapping FLIBs can be housed directly into the architecture of several flexible devices, such as robots and grippers, allowing to create multifunctionalities that go far beyond energy storage and include load‐bearing and variable flexibility. This study broadens the versatility of FLIBs toward energy storage structure engineering of flexible devices.

AbstractLarge‐area continuous covalent organic frameworks (COFs) film is highly desirable for the large‐scale continuous selective photocatalytic coupling of benzylamine (BA); however, traditional synthetic methods for preparing COFs films still suffer from the issues of harsh reaction condition, film breakage, and high energy‐consumption. Herein, a room‐temperature strategy is reported for making large‐area continuous imine‐based COFs film through the “infiltration‐reaction‐assembly” mechanism, demonstrating that such strategy is quite universal for making four types of large‐area COFs films. The as‐made PyTTA‐TPA (PyTTA: 1，3，6，8‐tetrakis(4‐aminophenyl)pyrene, TPA: p‐benzaldehyde) COFs film exhibits excellent catalytic performance for selective photocatalytic coupling of benzylamine (BA) with a high conversion rate of 98.2% and high selectivity of 97% in 3 h, which is the best photocatalytic performance in all reported photocatalysts. In addition, the as‐made COFs film is quite general for achieving photocatalytic coupling of other amine derivatives with outstanding photocatalytic performance of ≈100% conversion rate. Overall, this work brings a significant development for the room‐temperature synthesis of large‐area continuous COFs film to photocatalytic reaction.

AbstractMixed lead‐tin (Pb:Sn) halide perovskites are promising absorbers with narrow‐bandgaps (1.25–1.4 eV) suitable for high‐efficiency all‐perovskite tandem solar cells. However, solution processing of optimally thick Pb:Sn perovskite films is notoriously difficult in comparison with their neat‐Pb counterparts. This is partly due to the rapid crystallization of Sn‐based perovskites, resulting in films that have a high degree of roughness. Rougher films are harder to coat conformally with subsequent layers using solution‐based processing techniques leading to contact between the absorber and the top metal electrode in completed devices, resulting in a loss of VOC, fill factor, efficiency, and stability. Herein, this study employs a non‐continuous layer of alumina nanoparticles distributed on the surface of rough Pb:Sn perovskite films. Using this approach, the conformality of the subsequent electron‐transport layer, which is only tens of nanometres in thickness is improved. The overall maximum‐power‐point‐tracked efficiency improves by 65% and the steady‐state VOC improves by 28%. Application of the alumina nanoparticles as an interfacial buffer layer also results in highly reproducible Pb:Sn solar cell devices while simultaneously improving device stability at 65 °C under full spectrum simulated solar irradiance. Aged devices show a six‐fold improvement in stability over pristine Pb:Sn devices, increasing their lifetime to 120 h.
Great Enhancement in the Thermopower of Ionic Liquid by a Metal‐Organic Framework

Published: May 2023

AbstractTo efficiently harvest the abundant waste heat on earth is of great significance for sustainable development. Thermoelectric materials can be used to directly convert heat into electricity, and ionic thermoelectric materials like ionic liquids (ILs) are considered as the next‐generation thermoelectric materials. It is important to develop novel methods to improve the overall thermoelectric properties particularly the thermopower. Herein, the great enhancement in the thermopower of 1‐ethyl‐3‐methylimidazolium dicyanamide (EMIM:DCA) is reported that is an IL by introducing zeolitic imidazolate framework (ZIF‐8) that is a metal‐organic framework (MOF) for the first time. The presence of 40 wt.% ZIF‐8 can greatly increase the ionic thermopower of EMIM:DCA from 8.8 to 31.9 mV K−1 at room temperature, and the ZIF‐8/EMIM:DCA mixture at the ZIF‐8 loading of 10 wt.% can exhibit a ZTi value of 3.1, notably higher than that (0.59) of neat EMIM:DCA. The enhancement in the thermopower is attributed to the increase in the difference of the mobilities of EMIM+ and DCA− by ZIF‐8. Because DCA− is smaller while EMIM+ is larger than the pore size of ZIF‐8, the DCA− transport is hindered by ZIF‐8, while EMIM+ can bypass ZIF‐8.
