Prediction and classification of chemical composition of ancient glass objects based on generalized Shapley functions.

Ancient glass products have suffered from the baptism of time and experienced changes in the burial environment and weathering, resulting in a change in the proportions of their chemical composition and interfering with their accurate identification by later generations. In this paper, the chemical composition of ancient glass products is predicted and identified. First, the multivariate statistical ANOVA test is applied to explore the relationship between whether the cultural relics samples are weathered or not and the glass type, decoration, and color to derive a law of chemical composition of the cultural relics and to analyze the correlation and difference among the four factors.

Benefits and Barriers of Holistic Nursing Training by High-Fidelity Simulation in Obstetrics.

Background: With he technology of high-fidelity simulates developed, the clinical education route has changed. The nursing school pays attention on the use of high-fidelity simulations in nursing education. However, in China, only a few schools can afford the expensive teaching tools, including SimMom 3G and virtual reality (VR) devices, which also focus on "holistic nursing simulation.

Influence of one-day diabetes mellitus clinic management on blood glucose control and prognosis in patients with gestational diabetes mellitus.

Objective: To explore the influence of the one-day diabetes mellitus (DM) clinic management model on blood glucose control and prognosis in patients with gestational diabetes mellitus (GDM).

Methods: A total of 930 patients diagnosed with GDM by oral glucose tolerance test screening at 24-28 weeks of gestation were selected from those who underwent outpatient prenatal checkups at our hospital and were randomly divided into one-day DM clinic group ( = 509) and control group ( = 421). A one-day DM clinic intervention was conducted in the one-day DM clinic group, and individualized dietary interventions and exercise instruction were given in the control group.

Engineering hollow carbon spheres: directly from solid resin spheres to porous hollow carbon spheres via air induced linker cleaving.

Hollow carbon spheres (HCSs) have broad application in many fields such as catalysis, adsorption and energy storage. Due to various restrictions on hard and soft templates, self-templating methods have received extensive attention. Generally, the conventional self-templating method includes two steps, including the hollowing and carbonization process.

The Impact of the One-Day Clinic Diabetes Mellitus Management Model on Perinatal Outcomes in Patients with Gestational Diabetes Mellitus.

Objective: The aim of the present study was to explore the impact of the one-day clinic diabetes mellitus (DM) management model on perinatal outcomes in patients with gestational diabetes mellitus (GDM).

Methods: A total of 995 patients who underwent prenatal checkups at our hospital and were diagnosed with GDM by oral glucose tolerance test (OGTT) screening at 24-28 weeks of gestational age were enrolled between December 2018 and August 2020. The patients were randomly divided into a study group (541 cases) and a control group (454 cases).

Genome Wide Analysis for Growth at Two Growth Stages in A New Fast-Growing Common Carp Strain (Cyprinus carpio L.).

In order to identify candidate genes or loci associated with growth performance of the newly established common carp strain, Xinlong, we conducted a genome-wide association analysis using 2b-RAD technology on 123 individuals. We constructed two sets of libraries associated with growth-related parameters (weight, length, width and depth) measured at two different grow-out stages. Among the 413,059 SNPs identified using SOAP SNP calling, 147,131 were tested for GWAS after quality filtering.

Critical thickness of a surface-functionalized coating for enhanced lithium storage: a case study of nanoscale polypyrrole-coated FeS as a cathode for Li-ion batteries.

The encapsulation or coating of conductive materials is an effective strategy to increase the electrochemical ion-storage performance of some promising electrode materials such as transition metal oxides and sulfides, which are low-cost and have high capacity, but their practical applications are hindered by their intrinsically low conductivity and large volume changes during cycling; however, to date, the effect of the thickness of conductive layers on the ion-storage performance has been rarely studied. In this study, taking nanoscale polypyrrole (PPY)-coated FeS as an example, the effect of the critical thickness of the conductive PPY coating on the lithium-ion storage performance of (PPY)-coated FeS as a cathode of rechargeable lithium-ion batteries (LIBs) was investigated. Via a facile vapor-phase polymerization method, uniform PPY coatings with the thickness of 1-18 nm on microsized FeS particles were prepared.

Hemocompatible hemoadsorbent for effective removal of protein-bound toxin in serum.

Resin hemoperfusion is a life-saving treatment for drug intoxication or hepatic failure of patients. However, current resin adsorbents exhibit a limited hemocompatibility or low adsorption efficiency, representing a major roadblock to successful clinical applications. In this work, we developed a hemocompatible and effective hemoadsorbent based on polystyrene resin (H103) microparticles encapsulated in anti-biofouling zwitterionic poly(carboxybetaine) (PCB) hydrogels.

Antifouling zwitterionic hydrogel coating improves hemocompatibility of activated carbon hemoadsorbent.

Activated carbon has been widely used in hemoperfusion treatments. However, its performance has been significantly compromised by their poor hemocompatibility. In this work, we developed a novel antifouling adsorbent based on zwitterionic poly-carboxybetaine (PCB) hydrogel and powdered activated carbon (PAC) to improve hemocompatibility.

Natural zwitterionic l-Carnitine as efficient cryoprotectant for solvent-free cell cryopreservation.

Organic solvents, such as dimethyl sulfoxide (DMSO) and glycerol, have been commonly used as cryoprotectants (CPAs) in cell cryopreservation. However, their cytotoxicity and need of complex freezing protocols have impeded their applications especially in clinical cell therapy and regenerative medicine. Trehalose has been explored as a natural CPA to cryopreserve cells, but its poor cell permeability frequently results in low cryopreservation efficacy.

The hypothermic preservation of mammalian cells with assembling extracellular-matrix-mimetic microparticles.

Hypothermic preservation at a refrigerated temperature allows feasible and flexible storage of living cells, and is of great importance for the widespread use of cell-based applications, such as cell diagnostics and cell therapy. The University of Wisconsin (UW) cold storage solution is one of the current state-of-the-art protectants for hypothermic cell preservation. However, even by using the UW solution, the current effective preservation time under refrigerated conditions is still no more than 1 or 2 days, which restraints larger geographic cell-sharing regions.

Natural zwitterionic betaine enables cells to survive ultrarapid cryopreservation.

Cryoprotectants (CPAs) play a critical role in cryopreservation because they can resist the cell damage caused by the freezing process. Current state-of-the-art CPAs are mainly based on an organic solvent dimethyl sulfoxide (DMSO), and several DMSO-cryopreserved cell products have been brought to market. However, the intrinsic toxicity and complex freezing protocol of DMSO still remain as the bottleneck of the wide use for clinical applications.

The preservation of living cells with biocompatible microparticles.

Biomedical applications of living cells have rapidly expanded in many fields such as toxic detection, drug screening, and regenerative medicine, etc. Efficient methods to support cell survival and maintain activity in vitro have become increasingly important. However, traditional cryopreservation for living cell-based applications is limited by several problems.
