Published: July 2023

Background: Acute coronary syndrome patient outcomes have been improved using early invasive techniques. The aim of this study was to investigate the incidence, location, and severity of bleeding in PCI-treated cases to identify patient risk profiles and increased bleeding occurrences.
Methods: This prospective observational study evaluated percutaneous coronary angiography in 80 patients with hypertension and diabetes mellitus who planned to undergo primary or elective PCI. The cases were separated into 2 groups; those who reported bleeding (n=11) and those who did not (n=69). All patients underwent physical examination, laboratory evaluation, 12-lead electrocardiography, and PCI.
Results: In univariate regression analysis, age (OR: 1.09, 95% CI: 1.009 – 1.192), female gender (OR: 4.32, 95% CI: 1.157 – 16.131), history of peripheral arterial disease (OR: 7.31, 95% CI: 1.585 – 33.742), and femoral site of vascular access (OR: 9.6, 95% CI: 2.263 – 40.721) were independent predictors of major bleeding after PCI. In multivariate regression analysis, age (OR: 1.12, 95% CI:1.014 – 1.269), female gender (OR: 13.75, 95% CI: 1.983 – 161.2), history of peripheral arterial disease (OR: 43.38, 95% CI: 3.754 - 1042) and femoral site of vascular access (OR: 13.29, 95% CI: 2.233 – 128.5) were independent predictors of major bleeding after PCI.
Conclusions: Patients who reported bleeding after PCI had a significantly higher age, prevalence of female sex, serum creatinine, and transfemoral intervention before and after intervention compared to patients who did not report bleeding, while haemoglobin and transradial intervention before and after intervention were significantly lower in the bleeding cases than in the non-bleeding cases.

Published: July 2023

Hydrological modeling is a widely used approach for estimating the hydrological response of a basin to precipitation. Floods are among the most catastrophic natural disasters in small urban watersheds, inflicting loss of life, massive property destruction, and a severe danger to the economy. As a result, appropriate modeling can be a useful tool in preventing and mitigating such flood hazards. Despite this, flash flood prediction remains one of the challenges of hydrological modeling in ungauged basins due to a lack of runoff observations. This study aims to calibrate and validate the rainfall-runoff transformation model for Hathmati river sub watershed in the Sabarmati River basin using HEC-HMS (Hydrologic Engineering Centre Hydrology Modeling System). For the loss rate, SCS Curve Number method was selected while Clark Unit Hydrograph and SCS unit hydrograph was used for the transform method. The model is calibrated and verified using two rainfall-runoff events from 2006 and 2007 year The model calibration and validation efficiency were verified for both methods using the Nash-Sutcliffe efficiency (NSE), The coefficient of determination (R2), and the Percent Bias (PBIAS) As a result, the model calibration and validation were found to be satisfactory with the acceptable value of NSE between 0.869 to 0.914, with R2 0.901 to 0.947 and PBIAS from 9.76 to 14.8. it is observed that the model shows a very good correlation between simulated flow and observed flow. As a result, the model can be used to forecast river flow and aid in flood mitigation efforts to lessen their effects and associated costs. Additionally, the findings of this study can serve as guidelines for future assessments of the flood risk in the study area.

Aim: The aim of this study was to evaluate of the fertility indices of female mice exposed to Dimethoate and Beetroot Extract (Beta vulgaris).
Experimental Design: A completely randomized experimental design using standard methods for analysis.
Location and Duration of Study: This study was carried out in the Animal house, Department of Animal and Environmental Biology of Rivers State University, Nkpolu-Oroworukwo Port Harcourt, Nigeria. GPS 4o47'50''N 6o58'49''E. This study lasted for 21days.
Methodology: Thirty (30) sexually matured female mice were randomly divided into 6 groups (A-F) with 5 mice each. They were exposed for a period of 21 days to Dimethoate and 100% extract of Beta vulgaris. Group A was orally administered distilled water and rodent pellet only and acted as control. Group B was administered 20mg/kg/day of Dimethoate only. Group C was administered 5mg/kg/day of Dimethoate + 250mg/kg/day of 100% fresh extract of Beta vulgaris. Group D was administered 10mg/kg/day of Dimethoate + 250mg/kg/day of 100% fresh extract of Beta vulgaris. Group E was administered 15mg/kg/day of Dimethoate + 250mg/kg/day of 100% fresh extract of Beta vulgaris. Group F was administered 20mg/kg/day of Dimethoate + 250mg/kg/day of 100% fresh extract of Beta vulgaris. At the end of the 21 days exposure the final weight of the mice in each group was taken and blood collected by ocular puncture for hormonal profiling. Hormones such as Prolactin, Progesterone, estradiol, Follicle Stimulating Hormone (FSH) and luteinizing hormone (LH) were analyzed based on the manufacturer’s instruction using Randox Monza assay kit. The females were then allowed to mate with fifteen unexposed males in ratio 2:1. At the end of 24 days and following successful parturition essential data were collected from the F1 animals.
Results: Results showed significant increase in body weight for groups that were co-administered Beta vulgaris as compared to Group B that was administered Dimethoate only. Litter size gradually decrease significantly from seven in the control to two in group B which received Dimethoate only. Reproductive hormones significantly increased in groups coadministered Beta vulgaris and Dimethoate compared with group B administered Dimethoate only.
It is thus deduced that B. vulgaris might increase fertility in experimental animals, while Dimethoate showed significant impact on the reproduction in female experimental animals by reducing the fertility indices, such as reproduction hormones, reduction in fetal implantation leading to low number of offspring (Litter size).

Published: July 2023

AbstractLightweight and flexible electronic materials with high energy attenuation hold an unassailable position in electromagnetic stealth and intelligent devices. Among them, emerging heterodimensional structure draws intensive attention in the frontiers of materials, chemistry, and electronics, owing to the unique electronic, magnetic, thermal, and optical properties. Herein, an intrinsic heterodimensional structure consisting of alternating assembly of 0D magnetic clusters and 2D conductive layers is developed, and its macroscopic electromagnetic properties are flexibly designed by customizing the number of oxidative molecular layer deposition (oMLD) cycles. This unique heterodimensional structure features highly ordered spatial distribution, with an achievement of electron‐dipole and magnetic–dielectric double synergies, which exhibits the high attenuation of electromagnetic energy (160) and substantial improvement of dielectric loss tangent (≈200%). It can respond to electromagnetic waves of different bands to achieve multispectral stealth, covering visible light, infrared radiation, and gigahertz wave. Importantly, two kinds of ingenious information interaction devices are constructed with heterodimensional structure. The hierarchical antennas allow precise targeting of operating bands (S‐ to Ku‐ bands) by oMLD cycles. The strain imaging device with high sensitivity opens a new horizon for visual interaction. This work provides a creative insight for developing advanced micro–nano materials and intelligent devices.

In this study, high‐quality perovskite thin films and devices are fabricated with different fullerene‐based electron transport layers and different self‐assembled monolayers as hole transport layers. Then, a comparative study of a significant variety of different electrical, optical, and photoemission‐based characterization techniques is performed to quantify the properties of the solar cells, individual layers, and, importantly, the interfaces between them. In addition, the limitations and problems of the different measurements, the insights gained by combining different methods, and the different strategies for extracting information from the experimental raw data, are highlighted.

Published: July 2023

AbstractAll‐solid‐state lithium metal batteries (LMBs) are considered as the promising higher‐energy and improved‐safety energy‐storage systems. Nevertheless, the electrolyte‐electrodes interfacial issues due to the limited solid physical contact lead to discontinuous interfacial charge transport and large interfacial resistance, thereby suffering from unsatisfactory electrochemical performance. Herein, we construct an integrated cathode/polymer electrolyte for all‐solid‐state LMBs under the action of polymer chains exchange and recombination originating from multiple dynamic bonds in our well‐designed dynamic supramolecular ionic conductive elastomers (DSICE) molecular structure. The DSICE acts as polymer electrolytes with excellent electrochemical performance and mechanical properties, achieving the ultrathin pure polymer electrolyte thickness (12 μm). Notably, the DSICE also functions as lithium iron phosphate (LiFePO4, LFP) cathode binders with enhanced adhesive capability. Such well‐constructed Li|DSICE|LFP‐DSICE cells generate delicate electrolyte‐electrodes interfacial contact at the molecular level, providing continuous Li+ transport pathways and promoting uniform Li+ deposition, further delivering superior long‐term charge/discharge stability (>600 cycles, Coulombic efficiency, >99.8 %) and high capacity retention (80 % after 400 cycles). More practically, the Li|DSICE|LFP‐DSICE pouch cells show stable electrochemical performance, excellent flexibility and safety under abusive tests.

Published: July 2023

AbstractHigh‐valent iron‐oxo species are appealing for conducting O−O bond formation for water oxidation reactions. However, their high reactivity poses a great challenge to the dissection of their chemical transformations. Herein, we introduce an electron‐rich and oxidation‐resistant ligand, 2‐[(2,2′‐bipyridin)‐6‐yl]propan‐2‐ol to stabilize such fleeting intermediates. Advanced spectroscopies and electrochemical studies demonstrate a high‐valent FeV(O) species formation in water. Combining kinetic and oxygen isotope labelling experiments and organic reactions indicates that the FeV(O) species is responsible for O−O bond formation via water nucleophilic attack under the real catalytic water oxidation conditions.

Published: July 2023

AbstractBio‐based packaging materials are an emerging environment‐friendly alternative to conventional plastic food packaging materials, at least for some applications. The innovation of this work was to develop a sustainable cellulosic packaging material based on chitosan/palmitic acid/activated carbon coating with potential applications for single‐use food packaging. The study developed a multilayer paperboard (MPB), evaluating the effects of a paperboard surface coating by chitosan (2.0% w/w), palmitic acid (1.8% w/w), and activated carbon (1.2% w/w) applied in three coating layers. The water vapor transmission rate (WVTR) of coated paperboard was reduced compared to uncoated paperboard, associated with the coating suspension filling of the pores of the cellulosic matrix, the palmitic acid hydrophobic characteristic, and the nonpolar nature of activated carbon (acted by repelling the vapor molecules of water). A grease resistance of Kit solution 11 of MPB was observed. The stiffness and elongation capacity increased, indicating the rigidity and flexibility of the MPB. The deposition of palmitic acid and activated carbon influenced the roughness increase. The biodegradability in the soil after 188 days of MPB was 55.01%, and the control (uncoated paperboard) was 69.38%. The coating did not impact the degradation behavior of cellulose.
Nowhere to hide: Sea turtle bycatch in Northwest Africa

Published: July 2023

Abstract

Fisheries bycatch is considered the largest threat to sea turtle populations globally. However, it has been challenging to assess the impact of bycatch on sea turtles in some regions such as Northwest Africa (i.e. Cabo Verde, Guinea, Guinea–Bissau, Mauritania, Senegal, Sierra Leone and The Gambia) owing to large data gaps. This hampers effective management actions and interferes with conservation efforts in the region.
Five sea turtle species occur in Northwest Africa (i.e. green turtle Chelonia mydas, hawksbill Eretmochelys imbricata, leatherback Dermochelys coriacea, loggerhead Caretta caretta and olive ridley Lepidochelys olivacea). The region has regionally and globally important sea turtle nesting and foraging habitats and is a global fishing hotspot, with high and increasing fishing pressure.
Available information on sea turtle bycatch in Northwest Africa was compiled from peer‐reviewed and grey literature from 2010 onwards to determine the impact of artisanal and industrial fisheries (by gear type) on regional sea turtle populations and assess the level of threat to individual species.
All sea turtle species occurring in the region are impacted by bycatch. Reports suggest that green turtles and loggerheads have the highest bycatch rates, probably owing to their regional abundance and widespread distribution. Some of the potentially highest reported global bycatch rates (14,000–90,000 turtles/year/country) are noted, particularly in gillnets, longlines and handlines. However, further research is needed to understand mortality levels from artisanal fisheries and assess the impact of trawl fisheries operating in the region. Additional sources of mortality include deliberate capture for consumption or trade.
To strengthen regional sea turtle conservation and reduce sea turtle bycatch and mortality, urgent action is needed to implement and enforce national protection, establish a bycatch reduction framework (including gear modifications and spatio‐temporal closures), improve fisheries data collection and build capacity.
Early dynamic changes in iPSC oxygen consumption rate predict future cardiomyocyte differentiation

Published: July 2023

AbstractHuman induced pluripotent stem cells (iPSCs) hold great promise for reducing the mortality of cardiovascular disease by cellular replacement of infarcted cardiomyocytes (CMs). CM differentiation via iPSCs is a lengthy multiweek process and is highly subject to batch‐to‐batch variability, presenting challenges in current cell manufacturing contexts. Real‐time, label‐free control quality attributes (CQAs) are required to ensure efficient iPSC‐derived CM manufacturing. In this work, we report that live oxygen consumption rate measurements are highly predictive CQAs of CM differentiation outcome as early as the first 72 h of the differentiation protocol with an accuracy of 93%. Oxygen probes are already incorporated in commercial bioreactors, thus methods presented in this work are easily translatable to the manufacturing setting. Detecting deviations in the CM differentiation trajectory early in the protocol will save time and money for both manufacturers and patients, bringing iPSC‐derived CM one step closer to clinical use.
An idea to explore: Introduction to research methods
Authors: Basu Urmimala 
Published: July 2023

AbstractA curriculum description of a general introductory biology course titled “Introduction to Research Methods” is presented here. The course aims to provide a glimpse of biomedical research to students who have had no or limited exposure to research to encourage them to do research as freshmen. Thus, this course aims to better equip and invoke interest of high school and college students to undertake research by addressing specific knowledge gaps, recruiting students from underserved communities, and promoting teamwork, community learning, and equity. The course covers in broad strokes key topics like forming a hypothesis, chemical safety, research practices, chemical calculations, cloning and so forth, that is useful for undergraduate trainees initiated to research. The course also aims to put each topic in a social context that provides room for contemplating science for young trainee scientists thus addressing the gap between science and society. Student feedback reveals a positive learning experience and self‐reported improvement of knowledge on the various topics taught. As a result, the concepts and pedagogical tools used in this course can be adapted to increase students' involvement and retainment in biomedical research from underrepresented communities.

AbstractIntroductionThere is relatively little research on the association between personality traits and sustainable behaviors. So, this research was designed to differentiate associations between the six personality traits and sustainable behaviors perceived by individuals.MethodsA total of 1420 residents in a community of Nanjing participated in this survey. With the help of HEXACO‐60 and SBPI‐9, participants’ personality traits and the performance of sustainable behaviors perceived by individuals were measured. Subsequently, assisted by regression analysis, the quantitive relationship between HEXACO and sustainable behaviors perceived by individuals was explored.ResultsHonesty–humility (H–H), extraversion (X), consciousness (C), and openness to experience (O) are positively associated with sustainable behaviors perceived by individuals, whereas emotionality (E) and agreeableness (A) are negatively associated with it.ConclusionsHEXACO have a significant association with sustainable behaviors perceived by individuals. Additionally, H–H, E, X, A, C, and O could explain 44.2% of changes in sustainable behaviors perceived by individuals.

Published: July 2023

AbstractSmall‐Angle Scattering (SAS) techniques are essential tools for the characterization of catalysts before, during and after catalytic reactions. Either based on X‐Rays (SAXS) or neutrons (SANS), they provide unique structural information that helps to understand catalytic processes at the nanoscale level, allowing a rational improvement of the catalysts design. In this review, we present the key aspects involved in the use of these techniques in the catalysis field. Firstly, we introduce some of the fundamentals of the techniques and describe their main features and their impact in the catalyst design. Then, we analyze key examples of the use of SAS to study catalysts’ structure through ex situ analysis, focusing on examples involving different porous materials and metallic nanoparticles. Afterwards, we discuss in situ and operando approaches for studying catalytical processes monitored using SAS. Finally, we present perspectives and challenges for the future use of SAS in the catalysis field.

Published: July 2023

AbstractThe accurate identification of the transition velocities Utrans in bubble columns (BCs) is important for their effective design, operation, and scale‐up. In this work, a novel parameter, namely, the new hybrid index (NHI), was developed and successfully applied to gas holdup and pressure fluctuations recorded in various BCs operated with water and aqueous solutions of alcohols (ethanol and propan‐2‐ol). The first Utrans was identified on the basis of a well‐pronounced local NHI minimum, whereas the second Utrans was distinguished by the point from which the NHI profile levels off. It was concluded that the main Utrans depend on the type of gas‐liquid system and sparger used. A set of several Utrans is reported.

Published: July 2023

AbstractIn this paper, [Ni0.9Co0.1](OH)2 precursor is used to dope H3BO3 to synthesize positive electrode material when mixing lithium in wet method, and to explore the best doping by testing the microscopic morphology and electrochemical performance of the positive electrode material amount and calcination temperature. After doping with B, the microstructure of the material is improved, and the primary crystal grains are oriented and agglomerated into a needle shape. This good crystal structure can slow down the generation of grain microcracks and mechanical fracture, and improve the cycle stability of the positive electrode material. After doping B, the discharge specific capacity was slightly improved. When the calcination temperature is 750 °C and the doping amount of B is 1.0 mol%, the first discharge specific capacity reaches 223 mAh g−1. More importantly, the capacity retention rate of the battery after 100 cycles has been greatly improved, from 74 % without doping B to 87 %.
