The proposed strategy may open a new avenue for the development of powerful DNA molecular tools for cancer diagnosis.The anticancer efficacy of chemotherapeutic agents can be enhanced by the loading of DNA nanostructures, which is closely related to their interactions. This study achieved pH-responsive and targeted anthracycline delivery using i-motif and MUC1 aptamer co-modified DNA tetrahedron (MUC1-TD). The thermodynamic parameters for the binding of doxorubicin (DOX) and epirubicin (EPI) to MUC1-TD at pHs 7.4 and 5.0 were obtained. The smaller binding constant and the number of binding sites at pH 5.0 than at pH 7.4 indicated that acidic conditions favored the release of DOX and EPI loaded by MUC1-TD. The binding affinity of DOX was stronger than that of EPI at the same pH value due to their different chemical stereostructures. The intercalative binding mechanism was verified. In vitro release experiments revealed that acid pH and deoxyribonuclease I accelerated the release of DOX and EPI. The faster release rate of EPI than DOX was related to their binding affinity. In vitro cytotoxicity and cell uptake experiments revealed that the cytotoxicity of DOX and EPI loaded by MUC1-TD to MCF-7 cells was significantly higher than that to L02 cells. This work will provide theoretical guidance for the application of pH-responsive MUC1-TD nanocarriers in the field of pharmaceutics.The anaphase promoting complex/cyclosome (APC/C) is a large multi-subunit complex, regulating plant development and cell cycle. In plants, the APC/C gene family has been identified in Arabidopsis, rice, and maize. The APC/Cs in rose has not yet been reported. In this study, a total of 19 APC/C genes were identified in rose. Furthermore, we also investigated phylogenetic relationships, chromosomal distribution, gene structure, motif analysis, promoter sequence analysis and expression pattern of RhAPC/C genes. Synteny analysis indicated that AtAPC/Cs and RhAPC/Cs show a high degree of conservation. RhAPC/C promoters contains numerous cis-elements involved in plant morphogenesis, hormone response and stress response. Based on the transcription of RhAPC/Cs in different tissues and developmental stages, it appears that RhAPC/Cs may play a variety of roles in rose growth and development. RhAPC/Cs have limitations in the time and space during which they respond to hormones and abiotic stress. RhAPC5, RhAPC11d, RhAPC13a and RhAPC13c may play a role in rose responding to abiotic stress. The expression of RhAPC10 was altered by infection with fungal pathogen. Our study will serve as a basis for determining the functional role of APC/C genes in roses and help future research on woody plants.Cannabinoid receptors are widely distributed in many cells in Rheumatoid arthritis RA and strengthening factor to boost the development of RA diseases. Here, the hollow mesoporous copper sulfide (CuS) was used as the carrier skeleton and the cannabinoid type 2 (CB2) receptor agonist JWH133 was efficiently loaded inside of CuS through adsorption, then the outer layer was modified with hyaluronic acid (HA) to prevent the leakage of internal drugs. After the CuS-JWH133@HA nano carrier reached the target area, HA responsive cracked under RA microenvironment to realize the first step of accurate drug delivery of JWH133, and the thermally responsive CuS under near-infrared (NIR) promoted the release of internal drugs. Then, JWH133 specifically combined CB2 receptors on the surface of macrophage, synovial cells and osteoblasts to realize the second step of drug delivery. The inflammatory factors secreted by cells are significantly inhibited, and the activity of osteoblasts was significantly enhanced. Therapeutic effect by CuS-JWH133@HA of RA was well verified by decreasing levels of inflammation in vivo and improvement of inflamed and swollen joints of mice. The CuS-JWH133@HA nanocomposite showed satisfactory multidimensional therapeutic effect of RA in vitro and in vivo, which provided a novel idea for RA treatment.Recently, the food freshness indicator (FFI) has garnered great interest from consumers and food producers. A novel FFI based on bacterial nanocellulose (BNC)/zeolitic imidazolate framework-L (ZIF-L) and grape anthocyanins was developed and characterized using field emission scanning electron microscopy, Fourier-transform infrared, X-ray diffraction, water contact angle, and BET techniques. The results confirmed that the BNC fibrils were decorated by in situ growth of ZIF-L, with a 3D flower-shaped structure and randomly multiple sharp-edged petals, and hydroxyl and oxygenated heterocycle aromatic ring functional groups on its surface. The reversibility, color stability performance, and moisture sorption of FFI were studied and its applicability in a two-layer arrangement as a visual freshness monitoring of shrimp and minced beef was evaluated. The FFI was able to distinguish (ΔE > 5) the fresh, medium fresh, and spoiled minced meat and shrimp visually during 10 and 4 days of storage at 4 °C, respectively. Also, monitoring of food chemical and microbiological parameters approved the correlation of food spoilage with the color parameters of FFI. These results confirmed the function of ZIF-L in the fabrication of highly pH-sensitive food intelligent packaging material.Gastrointestinal cancer (GI) is one of the most serious and health-threatening diseases worldwide. Many countries have encountered an escalating prevalence of shock. Therefore, there is a pressing need to clarify the molecular pathogenesis of these cancers. The use of high-throughput technologies that allow the precise and simultaneous investigation of thousands of genes, proteins, and metabolites is a critical step in disease diagnosis and cure. Recent innovations have provided easy and reliable methods for genome investigation, including TALENs, ZFNs, and the CRISPR/Cas9 (clustered regularly interspaced palindromic repeats system). Among these, CRISPR/Cas9 has been revolutionary tool in genetic research. Recent years were prosperous years for CRISPR by the discovery of novel Cas enzymes, the Nobel Prize, and the development of critical clinical trials. This technology utilizes comprehensive information on genes associated with tumor development, provides high-throughput libraries for tumor therapy by developing screening platforms, and generates rapid tools for cancer therapy. This review discusses the various applications of CRISPR/Cas9 in genome editing, with a particular focus on genome manipulation, including infection-related genes, RNAi targets, pooled library screening for identification of unknown driver mutations, and molecular targets for gastrointestinal cancer modeling. Fasudil Finally, it provides an overview of CRISPR/Cas9 clinical trials, as well as the challenges associated with its use.Fucoidan (FU) is a natural sulfated polysaccharide with certain biological activity and has been shown to be an excellent nano-delivery material. In this study, ferulic acid (FA)-loaded FU nanoparticles (FA/FU NPs) were prepared and their nephroprotective mechanism was investigated. With a particle size of 158.6 ± 4.5 nm, FA/FU NPs increased the antioxidant activity of FA in vitro, possibly related to the increased dispersity of FA. In vitro results demonstrated that FA/FU NPs significantly protected human renal proximal tubule (HK-2) cells from cisplatin-induced damage, possibly by suppressing cisplatin-induced DNA damage and activating the cGAS-STING pathway. Furthermore, in vivo experiments confirmed that FA/FU NPs protected mice from cisplatin-induced acute kidney injury (AKI). Mechanistic studies confirmed that FA/FU NPs exerted nephroprotective effects by reducing MDA activity and increasing GSH and SOD activity. Our results demonstrated the potential of FU for delivering poorly soluble drug FA and protecting against cisplatin-induced AKI.Angiopoietin-like proteins, ANGPTL3, ANGPTL4, and ANGPTL8, are involved in regulating plasma lipids. In vitro and animal-based studies point to LPL and endothelial lipase (EL, LIPG) as key targets of ANGPTLs. To examine the ANGPTL mechanisms for plasma lipid modulation in humans, we pursued a genetic mimicry analysis of enhancing or suppressing variants in the LPL, LIPG, lipase C hepatic type (LIPC), ANGPTL3, ANGPTL4, and ANGPTL8 genes using data on 248 metabolic parameters derived from over 110,000 nonfasted individuals in the UK Biobank and validated in over 13,000 overnight fasted individuals from 11 other European populations. ANGPTL4 suppression was highly concordant with LPL enhancement but not HL or EL, suggesting ANGPTL4 impacts plasma metabolic parameters exclusively via LPL. The LPL-independent effects of ANGPTL3 suppression on plasma metabolic parameters showed a striking inverse resemblance with EL suppression, suggesting ANGPTL3 not only targets LPL but also targets EL. Investigation of the impact of the ANGPTL3-ANGPTL8 complex on plasma metabolite traits via the ANGPTL8 R59W substitution as an instrumental variable showed a much higher concordance between R59W and EL activity than between R59W and LPL activity, suggesting the R59W substitution more strongly affects EL inhibition than LPL inhibition. Meanwhile, when using a rare and deleterious protein-truncating ANGPTL8 variant as an instrumental variable, the ANGPTL3-ANGPTL8 complex was very LPL specific. In conclusion, our analysis provides strong human genetic evidence that the ANGPTL3-ANGPTL8 complex regulates plasma metabolic parameters, which is achieved by impacting LPL and EL. By contrast, ANGPTL4 influences plasma metabolic parameters exclusively via LPL.

To compare acute care virtual visits with in-person visits with respect to equity of access, markers of quality and safety, and parent and provider experience, before and during the coronavirus disease 2019 pandemic.

We compared patient demographics, antimicrobial prescribing rates, emergency department (ED) use, and patient-experience scores for virtual visits and in-person care at 2 academic pediatric primary care practices using χ

testing and interrupted time series analyses. Parent and provider focus groups explored themes related to virtual visit experience and acceptability.

We compared virtual acute care visits conducted in March 2020-February 2021 (n=8868) with in-person acute care visits conducted in February 2019-March 2020 (n=24 120) and March 2020-February 2021 (n=6054). There were small differences in patient race/ethnicity across the different cohorts (P<.01). Virtual visits were associated with a 9.6% (-11.5%, -7.8%, P<.001) decrease in all antibiotic prescribing and a 13.2% (-22.d avoid creating disparities in access to virtual care will be essential to continued success of telehealth acute care visits.

To determine the whether a greater percentage of deaths of infants born at term among US-born (vs foreign-born) women is attributable to paternal nonacknowledgement.

Using a cross-sectional population-based design, stratified and multivariable binomial regression analyses were performed on a subset of the 2017 National Center for Health Statistics linked live birth-infant death cohort dataset of singleton infants born at term (37-42weeks) of US-born (N=2 127 243) and foreign-born (N=334 664) women.

Infants of US-born women had a prevalence of paternal nonacknowledgement of 11.3% vs 7.5% for foreign-born women, P<.001. The infant mortality rate of term births to US-born women with paternal nonacknowledgment equaled 5.0/1000 vs 2.0/1000 for those with paternal acknowledgment; relative risk (RR)=2.47 (2.31, 2.86). The infant mortality rate of term births to foreign-born women with paternal nonacknowledgment equaled 2.5/1000 vs 1.6/1000 for those with paternal acknowledgment, RR=1.61 (1.24, 2.10). The adjusted (controlling for selected covariates) RR of first-year mortality of term births among US-born and foreign-born women with nonacknowledged (vs acknowledged) fathers equaled 1.
