Coronary atherosclerosis is a potentially chronic circulatory condition that endangers human health. The biological cause underpinning cardiovascular disease is coronary atherosclerosis, and acute cardiovascular events can develop due to thrombosis, platelet aggregation, and unstable atherosclerotic plaque rupture. Coronary atherosclerosis is progressive, and three specific changes appear, with fat spots and stripes, atherosclerosis and thin-walled fiber atherosclerosis, and then complex changes in arteries. The progression and severity of cardiovascular disease are correlated with various levels of calcium accumulation in the coronary artery. The therapy and diagnosis of coronary atherosclerosis benefit from the initial assessment of the size and degree of calcification. This article will discuss the new progress in the early diagnosis of coronary atherosclerosis in terms of three aspects: imaging, gene and protein markers, and trace elements. This study intends to present the latest methods for diagnosing patients with early atherosclerosis through a literature review.

Flexible energy storage devices have played a significant role in multiscenario applications, while flexible zinc‐ion batteries (ZIBs), as an essential branch, have developed rapidly in recent years. Three‐dimensional (3D) printing is an extremely advanced technology to design and modify the structure of batteries and provides unlimited possibilities for the diversified development of energy storage equipment. Herein, by utilizing 3D printing technology, carbon nanotube (CNT) is coated by MnO2 to form a flexible CNT@MnO2 ink as a cathode for flexible aqueous micro‐ZIBs for the first time and zinc powder ink is used as an anode due to its high flexibility and bendability. The Zn//CNT@MnO2 flexible battery shows a stable capacity of 63 μAh cm−2 at 0.4 mA cm−2. When the battery is bent in different states, the maximum capacity loss compared with the initial value is only 2.72%, indicating its stability. This study shows the potential of 3D printing technology in the development of flexible manganese‐based ZIBs.

Pneumatosis of the portal vein is considered a rare imaging sign rather than a disease. It usually occurs in patients with digestive tract diseases such as intestinal obstructive diseases, mesenteric vascular diseases, closed abdominal trauma, and liver transplantation. Because of its high mortality rate, it is also termed the “sign of death.” Hawthorn contains tannic acid, and seafood is rich in calcium, iron, carbon, iodine, and other minerals and proteins. Thus, consuming both hawthorn and seafood together can result in the formation of an indigestible complex in the body, acting as the main pathogenic factor in patients with intestinal obstruction. We herein describe a patient with duodenal obstruction caused by hawthorn who developed the hepatic portal venous gas sign and was cured by nonsurgical treatment.

Although elderly users comprise a major user group in the field of mobile health (mHealth) services, their adoption rate of such services is relatively low compared with their use of traditional health services. Increasing the adoption rate of mHealth services among elderly users is beneficial to the aging process. This study aimed to examine the determinants of mHealth service use intentions using a trust transfer model among elderly users facing declining physiological conditions and lacking support from hospitals. A survey comprising 395 users aged 60 years and above was conducted in China to validate our research model and hypotheses. The results reveal that (1) trust in mHealth services positively influences use intentions, (2) trust in offline health services positively influences trust in mHealth services, (3) declining physiological conditions strengthen the effects of trust in offline health services regarding trust in mHealth services, (4) support from hospitals weakens the effects of trust in mHealth services on use intentions, and (5) the relationship between trust in offline health services and intention to use mHealth services is partially mediated by trust in mHealth services. The independent variables and moderators collectively explain a 48.3% variance in the use intention of mHealth services. We conclude that the trust transfer theory is useful in explaining the development of initial trust in mHealth services. In addition, declining physiological conditions and support from hospitals are important factors for investigating the adoption of mHealth services among elderly users.

Angiosperms represent one of the most spectacular terrestrial radiations on the planet 1 , but their early diversification and phylogenetic relationships remain uncertain 2 – 5 . A key reason for this impasse is the paucity of complete genomes representing early-diverging angiosperms. Here, we present high-quality, chromosomal-level genome assemblies of two aquatic species—prickly waterlily ( Euryale ferox ; Nymphaeales) and the rigid hornwort ( Ceratophyllum demersum ; Ceratophyllales)—and expand the genomic representation for key sectors of the angiosperm tree of life. We identify multiple independent polyploidization events in each of the five major clades (that is, Nymphaeales, magnoliids, monocots, Ceratophyllales and eudicots). Furthermore, our phylogenomic analyses, which spanned multiple datasets and diverse methods, confirm that Amborella and Nymphaeales are successively sister to all other angiosperms. Furthermore, these genomes help to elucidate relationships among the major subclades within Mesangiospermae, which contain about 350,000 species. In particular, the species-poor lineage Ceratophyllales is supported as sister to eudicots, and monocots and magnoliids are placed as successively sister to Ceratophyllales and eudicots. Finally, our analyses indicate that incomplete lineage sorting may account for the incongruent phylogenetic placement of magnoliids between nuclear and plastid genomes. Genome assemblies of two aquatic species, prickly waterlily and rigid hornwort, clarify the early diversification and phylogeny of plants. Multiple independent polyploidization events are inferred in each of the five major angiosperm clades.

Background Agarwood, generated from the Aquilaria sinensis , has high economic and medicinal value. Although its genome has been sequenced, the ploidy of A. sinensis paleopolyploid remains unclear. Moreover, the expression changes of genes associated with agarwood formation were not analyzed either. Results In the present work, we reanalyzed the genome of A. sinensis and found that it experienced a recent tetraploidization event ~ 63–71 million years ago (Mya). The results also demonstrated that the A. sinensis genome had suffered extensive gene deletion or relocation after the tetraploidization event, and exhibited accelerated evolutionary rates. At the same time, an alignment of homologous genes related to different events of polyploidization and speciation were generated as well, which provides an important comparative genomics resource for Thymelaeaceae and related families. Interestingly, the expression changes of genes related to sesquiterpene synthesis in wounded stems of A. sinensis were also observed. Further analysis demonstrated that polyploidization promotes the functional differentiation of the key genes in the sesquiterpene synthesis pathway. Conclusions By reanalyzing its genome, we found that the tetraploidization event shaped the A. sinensis genome and contributed to the ability of sesquiterpenes synthesis. We hope that these results will facilitate our understanding of the evolution of A. sinensis and the function of genes involved in agarwood formation.

High‐entropy materials (HEMs) possess unique properties that can be tailored for specific performance characteristics, making them suitable for various battery applications. In particular, HEMs have shown significant promise in enhancing the electrochemical performance of Prussian blue analogues (PBAs) across various battery systems, including sodium‐ion, potassium‐ion, lithium‐sulfur, aqueous zinc‐ion, and aqueous ammonium‐ion batteries. This article examines case studies to explore how the high‐entropy strategy enhances PBA performance. It also provides an overview of traditional metal substitution methods in modifying the two main types of PBAs, that is, Fe‐based and Mn‐based PBA electrode materials. Additionally, other optimization methods, such as defect modulation, surface modification, composite structures, and electrolyte modulation, are also discussed. Finally, the article delves deeply into the relationship between high‐entropy techniques and traditional metal substitution in modifying PBA electrode materials from the perspectives of element design and performance enhancement, aiming to provide comprehensive theoretical guidance for readers. The high‐entropy strategy has demonstrated significant potential in enhancing the electrochemical performance of Prussian blue analogues (PBAs) across various battery systems. This paper delves into the relationship between high‐entropy strategy and traditional metal substitution methods and innovatively summarizes three key characteristics of high‐entropy PBAs: structural stability, disorder characteristics, and strong synergistic properties.

Cotton is a major fiber plant, which provides raw materials for clothing, protecting humans from the harsh environment of cold or hot weathers, enriching the culture and custom of human societies. Due to its importance, the diploid and tetraploid genomes of different cotton plants have been repeatedly sequenced to obtain their complete and fine genome sequences. These valuable genome data sets revealed the evolutionary past of the cotton plants, which were recursively affected by polyploidization, with a decaploidization contributing to the formation of the genus Gossypium , and a neo-tetraploidization contributing to the formation of nowadays widely cultivated cotton plants. Post-polyploidization genome instability resulted in numerous structural changes of the genomes, such as gene loss, DNA inversion and translocation, illegitimate recombination, and accumulation of repetitive sequences, and functional innovation accompanied by elevated evolutionary rates of genes. Many these changes have been asymmetric between subgnomes of the tetraploid cottons, rendering their divergent profiles of biological regulation and function. The availability of whole-genome sequences has now paved the way to identify and clone functional genes, e.g., those relating to fiber development, and to enhance breeding efforts to cultivate cottons to produce high-yield and high-quality fibers, and to resist environmental and biological stress.

With the advent of wearable communication devices, microstrip antennas have developed multiple applications due to their ultra-low-profile properties. Therefore, it is essential to analyze the problem of frequency shift and impedance mismatch when the antenna is bent. For the case of a rectangular patch antenna E-plane bent on the cylindrical surface, (1) this paper introduces the effective dielectric constant into the cavity model, which can accurately predict the resonance frequency of the antenna, and (2) according to the equivalent circuit model of the antenna resonance mode, the lumped element parameters are calculated based on the above effective dielectric constant, so that impedance characteristics and the S-parameter matching the port can be quickly constructed. From the perspective of circuit frequency characteristics, it explains the change in the transmission performance of the curved antenna. The experimental results show that the maximum difference between the experimental and theoretical calculation frequencies is less than 1%. These results verify the validity and applicability of the theory in the analysis of ultra-low-profile patch antennas and wearable electronic communication devices. It provides a theoretical basis for the fast impedance matching of patch antennas under different working conditions.
