Published: May 2023

AbstractCombining metal complexes with amphiphilic molecules leads to a wide variety of functional self‐assembled nanostructures. Metal complexes exhibiting spin transitions can be good candidates as the trigger to cause structural conversion of such assembly because they respond to various external stimuli. In this work, we studied a structural conversion of a supramolecular assembly containing a [Co2Fe2] complex through a thermally induced electron transfer‐coupled spin transition (ETCST). With an amphiphilic anion, the [Co2Fe2] complex formed reverse vesicles in solution and showed thermal ETCST. In contrast, thermal ETCST in the presence of a bridging hydrogen‐bond donor caused structural conversion from the reverse vesicle structure to entangled one‐dimensional chains through hydrogen bond formation.

Comprehensive SummaryA core feature of two‐dimensional covalent organic frameworks is crystallinity, but it remains challenging to gain their thin films with high crystallinity. Here, we presented growth of thin films of two‐dimensional covalent organic frameworks with an average domain size of ~2.83 μm2 and maximum domain size of up to ~26.19 μm2 using amphiphilic glycine derivatives on water surface. We envisage that this work will inspire the growth of a wide variety of organic two‐dimensional materials with high crystallinity and boost their structure property investigations.

Published: May 2023

AbstractPatients with hereditary angioedema (HAE) experience a high burden of disease due to unpredictable, painful, disfiguring, and potentially life‐threatening HAE attacks. Multiple HAE‐specific medications for the on‐demand treatment, short‐term and long‐term prophylaxis of HAE attacks have entered the market in recent years; however, the availability and access to these medications may vary between different countries. For this review, PubMed and EMBASE databases were searched for guidelines, consensus statements, and other publications on HAE management as well as publications on quality of life in patients with HAE. The current guidelines and recent literature on HAE management in specific countries are summarized with the aim to highlight the similarities and differences between guideline recommendations and the country‐specific clinical practice. Improvement in quality of life, which is a key goal in HAE management, is also discussed and the country‐specific trends are highlighted. Finally, the ways to achieve a more patient‐centric approach to HAE management within the framework set by the clinical management guidelines are examined.

AbstractIn this work, we develop numerical methods for the solution of blood flow and coagulation on dynamic adaptive moving meshes. We consider the blood flow as a flow of incompressible Newtonian fluid governed by the Navier–Stokes equations. The blood coagulation is introduced through the additional Darcy term, with a permeability coefficient dependent on reactions. To this end, we introduce moving mesh collocated finite‐volume methods for the Navier–Stokes equations, advection–diffusion equations, and a method for the stiff cascade of reactions. A monolithic nonlinear system is solved to advance the solution in time. The finite volume method for the Navier–Stokes equations features collocated arrangement of pressure and velocity unknowns and a coupled momentum and mass flux. The method is conservative and inf‐sup stable despite the saddle point nature of the system. It is verified on a series of analytical problems and applied to the blood flow problem in the deforming domain of the right ventricle, reconstructed from a time series of computed tomography scans. At last, we demonstrate the ability to model the coagulation process in deforming microfluidic capillaries.

Published: May 2023

AbstractCotton and its blends are among the most common textiles used. Although cotton is a highly flammable material, its flammability may be reduced with a retardant coating. We developed an architectural build of organic/inorganic coating with layer‐by‐layer (LbL) assembly of the cationic polyethyleneimine (PEI) and anionic halloysite clay nanotubes (HNT) on raw cotton. The biocompatible SiO2/Al2O3 HNTs have a 50‐nm diameter hollow structure that can carry chemicals and ensures safe interactions of treated textiles with living organisms. The treated cotton was characterized using TGA, SEM, TEM, and IR spectroscopy for optimization of the finishing process. The nanoclay‐coated cotton was burned to determine the extent of fire protection and resulted in the flame self‐extinguishing. Adding only two bilayers of PEI/HNT coating, which accounted for ca 7 wt.% of the tissue, was shown to give an optimal level of flame retardancy to the processed cotton; further nanoclay layering increased flame retardancy at a diminishing rate and may not be necessary in industrial processes. These clay nanotubes were also loaded with color‐enhancing dyes, antimicrobial chloramphenicol or silver, providing architectural coatings with complex functionality. This proposed green technology combines natural cotton fibers, and abundantly available halloysite clay in this new nanocomposite textile product.

AbstractPloidy manipulation has been used in many crop improvement programs to develop plant species with wider adaptability and desirable traits. The objectives of this study were to create stable tetraploid centipedegrass (Eremochloa ophiuroides [Munro] Hack.) lines and evaluate them for beneficial traits. To generate polyploid lines, “TifBlair” (2n = 2x = 18) seeds were exposed to gamma radiation and callus was generated using tissue culture, exposed to glyphosate and regenerated into plantlets. After 5 years of continuous propagation, two lines, Hongliang Wang (HW)16 and HW123, were found to be tetraploid, and one line, HW61, was found to be a mixoploid using flow cytometry and chromosome counts. Nuclear DNA contents for diploid and tetraploid lines ranged from 1.97 to 2.10 and 4.14 to 4.30 pg 2C−1, respectively. Ten centipedegrass lines were genotyped using seven simple sequence repeat markers and clustered by origin (derived from TifBlair or the University of Georgia breeding program). Six lines were evaluated for morphological and physiological traits under greenhouse conditions. Trait evaluation showed that tetraploid lines had larger stomata and leaf width and reduced stomatal density. For all other traits evaluated under greenhouse conditions, although significant differences were observed between lines, no consistent differences separated diploid and tetraploid lines. Between the tetraploid lines, HW16 had higher evapotranspiration, percentage green cover, and relative water content than HW123, whereas HW123 had a higher average clipping yield and root width than HW16. In conclusion, irradiation and tissue culture are valuable techniques for the generation of stable polyploid lines, and an increased ploidy level led to larger vegetative structures in centipedegrass.

AbstractMolecular markers such as single nucleotide polymorphisms (SNPs) and SilicoDArT are important in dissecting the genetic diversity of a population at DNA level. The two marker types were analyzed using the same genotyping platform. Although the two marker types were analyzed using the same genotyping platform, they were filtered using a different marker stringency. We determined the genetic diversity of 623 half‐sibs of shea tree (Vitellaria paradoxa a C. F. Gaertn. nilotica) assembled from five geographical locations (Katakwi, Otuke, Amuru, Moyo, and Arua) in Uganda's shea parklands. A total of 27,063 Diversity Arrays Technology (DArT) SNP and 9018 SilicoDArT markers were used to assess genetic diversity and population structure. The populations showed a low genetic diversity (Gst = 0.21), very low population differentiation (FST = 0.02), low‐to‐moderate linkage disequilibrium (r = 0.2), and Hardy–Weinberg Equilibrium (HWE = 0.1982). The study further revealed a higher genetic diversity within population (0.26) than among the population (0.21). A high level of heterozygosity was observed within individuals (0.26) and markers (0.32) revealing a high non‐random association of alleles at different loci that offer opportunities to design association studies and allele transfer in marker‐assisted selection in the population. The markers varied in their polymorphic information content values (SilicoDArT = 0.11) and (SNPs = 0.15) on genetic diversity. This study reveals the importance of genetic diversity and population structure analysis using high‐density DArT‐Seq SilicoDaRT and SNP makers in the conservation and breeding of shea tree in Uganda.
Promotive effects of endophytic rhizobacteria on tiller and root growth in creeping bentgrass during drought stress and post‐stress recovery involving regulation of hormone and sugar metabolism

AbstractStress‐induced accumulation of ethylene exacerbates drought damages in plants and suppressing stress induction of ethylene may promote plant tolerance to drought stress. The objective of this study was to investigate the effects of endophytic bacteria (Paraburkholderia aspalathi) with 1‐aminocyclopropane‐1‐carboxylic acid (ACC) deaminase enzymes in suppressing ethylene production on plant tolerance to drought stress and post‐stress recovery and the underlying physiological mechanisms of P. aspalathi‐regulation in creeping bentgrass (Agrostis stolonifera L.). A novel strain of P. aspalathi, "WSF23," with ACC deaminase activity was used to inoculate the roots of creeping bentgrass plants (cv. "Penncross") subjected to drought stress for 35 days and rewatered for 15 days (post‐stress recovery) in controlled‐environment growth chambers. Inoculation with WSF23 bacteria resulted in an increased number of tillers, tillering production rate, root viability, and root growth (quantified in length, surface area, volume, and dry weight) during drought stress or rewatering. Inoculation of plants with WSF23 bacteria increased cytokinin (CK) (c‐Zeatin and tZ‐riboside) and jasmonate (JA‐Ile) content and reduced ACC and abscisic acid (ABA) content in roots during drought or rewatering. Sugar accumulation in crowns was promoted by inoculation during drought stress. The differential changes in ACC, CK, ABA, and JA‐Ile and sugar accumulation due to the bacterial inoculation could contribute to ACC deamination bacteria‐improved drought tolerance and post‐stress recovery in terms of tiller production and root proliferation and elongation in creeping bentgrass.

AbstractSolar water evaporation is an efficient and sustainable technology. To reduce energy consumption and improve cost efficiency, the surface modification of wood sponge by polypyrrole‐glutathione (PGWS) was achieved using an in‐situ synthetic method. The PGWS exhibits excellent adsorption efficiency for Hg(II) ions with adsorption capacity of 330.8 mg g−1 at 25 °C. Following Hg(II) absorption, the PGWS could be upcycled for solar steam generation. A stackable device was constructed by placing two wood sponges under a Hg(II) saturated PGWS [PGWS‐Hg(II)], this system exhibited the highest water evaporation rate of 2.14 kg m−2 h−1 under 1 kW m−2. Moreover, collecting paper was inserted between the stacked PGWS‐Hg(II) and wood sponge for the collection of salts. As such salt can be successfully collected from simulated fertilizer plant effluent and then used as a nutrient for growing plants using a hydroponic system. The facile design of stackable evaporation provides an opportunity for wastewater utilization by harvesting solar energy.

Published: May 2023

SummaryIn light of the increasing share of renewable energy sources (RES) in electricity generation, the research community is directing their attention toward developing highly efficient DC‐DC high‐gain step‐up converters. These converters are designed to exhibit reduced voltage stress on the switching devices (semiconductors). This paper presents a comprehensive study of a switch voltage stress‐reduced step‐up converter that offers a range of additional features, including the availability of a common ground point, continuous input current, simple two‐mode continuous conduction mode (CCM) operation, wide duty cycle range, and quadratic boosting factor. To achieve the aforementioned features, the converter utilizes two switches with the same operating modes, eliminating the need for complex switching circuitry. Operational modes, steady‐state analysis, and design considerations have been presented in detail. Comparative analysis indicates that the voltage conversion ratio per number of devices in the proposed topology is significantly higher than that of similar topologies. In addition, the voltage stress of switches is considerably less than the topologies addressed in the literature. The study further includes detailed mathematical and experimental analyses, small signal analysis, and hardware implementation to support the theoretical findings. The converter's efficiency has been thoroughly analyzed along with thermal analysis to ensure its reliability.
Resolving 31 colors on a standard 3‐laser full spectrum flow cytometer for immune monitoring of human blood samples

Published: May 2023

AbstractImmune monitoring of patients on a single‐cell level is becoming increasingly important in various diseases. Due to the often very limited availability of human specimens and our increased understanding of the immune systems there is an increasing demand to analyze as many markers as possible simultaneously in one panel. Full spectrum flow cytometry is emerging as a powerful tool for immune monitoring since 5‐laser instruments enable characterization of 40 parameters or more in a single sample. Nevertheless, even if only machines with fewer lasers are available, development of novel fluorophore families enables increasing panel sizes. Here, we demonstrate that careful panel design enables the use of 31‐color panels on a 3‐laser Cytek® Aurora cytometer for analyzing human peripheral blood leukocytes, without the need for custom configuration and using only commercially available fluorochromes. The panel presented here should serve as an example of a 31‐fluorochrome combination that can be resolved on a 3‐laser full spectrum cytometer and that can be adapted to comprise other (and possibly more) markers of interest depending on the research focus.
Diabetes, COVID‐19, and questions unsolved

Published: May 2023

AbstractRecent evidence suggests a role for Diabetes Mellitus in adverse outcomes from COVID‐19 infection; yet the underlying mechanisms are not clear. Moreover, attention has turned to prophylactic vaccination to protect the population from COVID‐19‐related illness and mortality. We performed a comprehensive peer‐reviewed literature search on an array of key terms concerning diabetes and COVID‐19 seeking to address the following questions: 1. What role does diabetes play as an accelerator for adverse outcomes in COVID‐19?; 2. What mechanisms underlie the differences in outcomes seen in people with diabetes?; 3. Are vaccines against COVID‐19 efficacious in people with diabetes? The current literature demonstrates that diabetes is associated with an increased risk of adverse outcomes from COVID‐19 infection, and post‐COVID sequelae. Potential mechanisms include dysregulation of Angiotensin Converting Enzyme 2, Furin, CD147, and impaired immune cell responses. Hyperglycaemia is a key exacerbator of these mechanisms. Limited studies are available on COVID‐19 vaccination in people with diabetes; however, the current literature suggests that vaccination is protective against adverse outcomes for this population. In summary, people with diabetes are a high‐risk group that should be prioritised in vaccination efforts. Glycaemic optimisation is paramount to protecting this group from COVID‐19‐associated risk. Unsolved questions remain as to the molecular mechanisms underlying the adverse outcomes seen in people with diabetes; the functional impact of post‐COVID symptoms on people with diabetes, their persistence, and management; how long‐term vaccine efficacy is affected by diabetes, and the antibody levels that confer protection from adverse outcomes in COVID‐19.

Published: May 2023

AbstractBlack‐headed penduline tit (Remiz macronyx) is a poorly known bird species mainly distributed in Iran, Turkmenistan, and Kazakhstan. The distribution of black‐headed penduline tit is disjointed and fragmented, and it occurs only along lakes or rivers surrounded by extensive reedbeds. Four subspecies of R. macronyx have been recognized (macronyx, neglectus, nigricans, and ssaposhnikowi). The ssaposhnikowi subspecies was previously known to occur only around lakes in southeastern Kazakhstan. In this study, we reported the first confirmed breeding record of R. m. ssaposhnikowi in the Nalati wetland, Ili, Xinjiang, China, extending the distribution range of the black‐headed penduline tit by 350 km to the east. We also obtained new information about the morphology and breeding behavior of R. m. ssaposhnikowi, which can be useful for the taxonomy of penduline tits, especially in distinguishing black‐headed penduline tits from Eurasian penduline tits (R. pendulinus).
Parasite‐mediated selection on host phenology
Authors: MacDonald Hannelore , Brisson Dustin 
Published: May 2023

AbstractThe timing of seasonal activity, or phenology, is an adaptive trait that maximizes individual fitness by timing key life events to coincide with favorable abiotic factors and biotic interactions. Studies on the biotic interactions that determine optimal phenology have focused on temporal overlaps among positively‐interacting species such as mutualisms. Less well understood is the extent that negative interactions such as parasitism impact the evolution of host phenology. Here, we present a mathematical model demonstrating the evolution of host phenological patterns in response to sterilizing parasites. Environments with parasites favor hosts with shortened activity periods or greater distributions in emergence timing, both of which reduce the temporal overlap between hosts and parasites and thus reduce infection risk. Although host populations with these altered phenological patterns are less likely to mature and reproduce, the fitness advantage of parasite avoidance can be greater than the cost of reduced reproduction. These results illustrate the impact of parasitism on the evolution of host phenology and suggest that shifts in host phenology could serve as a strategy to mitigate the risk of infection.

AbstractPositive associations between animals and foundational shrub species are frequent in desert ecosystems for shelter, resources, refuge, and other key ecological processes. Herein, we tested the impact of the density of the shrub species Ephedra californica on the presence and habitat use of the federally endangered lizard species, Gambelia sila. To do this, we used a 3‐year radio telemetry dataset and satellite‐based counts of shrub density across sites at the Carrizo Plain National Monument in San Luis Obispo County, CA. The effect of shrub density on lizard presence was contrasted with previous shrub cover analyses to determine whether measures of shrub density were superior to shrub cover in predicting lizard presence. Increasing shrub density increased lizard presence. As shrub density increased, lizards were located more frequently “above ground” versus “below ground” in burrows. Male lizards had significantly larger home ranges than females, but both sexes were similarly associated with increasing shrub densities. Shrub density and shrub cover models did not significantly differ in their prediction of lizard presence. These findings suggest that both habitat measures are effective analogs and that ecologically, both cover and the density of foundation shrub species are key factors for some desert lizards.
