Human pluripotent stem cells are a powerful tool to study development, to model diseases or as cellular substrates for drug screening. We generated a human induced pluripotent stem cell (hiPSC) line from a healthy control donor. Peripheral blood mononuclear cells (PBMCs) from this donor were reprogrammed using integration-free Sendai virus. This cell line had normal karyotype, expressed pluripotency hallmarks and differentiated into the three primary germ layers.

Patients with longstanding progressive collapsing foot deformity often develop osteoarthritis of the ankle, midfoot, or hindfoot joints, which can be symptomatic or lead to fixed deformities that complicate treatment. The development of deformity is likely caused by ligament degeneration and tears. However, the effect of individual ligament tears on changes in joint contact mechanics has not been investigated.

A validated finite element model of the foot was used to compare joint contact areas, forces, and pressures between the intact and collapsed foot, and to evaluate the effect of individual ligament tears on joint contact mechanics.

Collapsing the foot resulted in an increase in contact pressure in the subtalar, calcaneocuboid, tibiotalar, medial naviculocuneiform, and first tarsometatarsal joints but a decrease in contact pressure in the talonavicular joint. Rupture of the spring ligament was the main contributor to increased calcaneocuboid and subtalar joint contact pressures and decreased medial ment tears and joint contact pressures could provide support for the use of ligament reconstructions to prevent the development of arthrosis.Ozone (O3) pollution poses health risks and premature mortality, and gas stations are one of the largest sources of urban volatile organic compounds (VOCs, the main precursor to O3). This paper investigates whether the government's call for night refueling, which can be regarded as a green nudge, can guide changes in consumer behavior and consequently improve environmental quality. Using a difference-in-differences (DID) estimation and weekly monitoring site air quality panel data, we analyze the effect of the Night Refueling Preferential Policy on O3 concentrations. We find that the policy can reduce O3 concentrations by 10% by encouraging consumers to refuel at night. The reduction in O3 has brought great benefits to human health, leading to a 4-5‰ reduction in non-accidental mortality and a 6-8‰ reduction in cardiovascular mortality in Jiangsu province. The economic benefits of this policy would be approximately 62-189 billion Chinese Yuan (CNY) if it were implemented nationwide. The findings of this study suggest that the government can influence consumer behavior to promote environmental quality.Loess Plateau is important for maize production in China. Therefore, a good understanding of soil phosphorus (P) behavior in the Loess region is crucial for optimizing fertilization in its agriculture systems. To date, research on factors influencing P adsorption/desorption has mainly focused on fertilization. Widespread application of straw return and increasing soil fauna in agricultural croplands inevitably affect soil P behavior either directly or indirectly in this area. However, less attention has been focused on these effects and their interactions. Here, a field plot experiment was performed based on a completely randomized design to investigate the response of P adsorption-desorption characteristics to the presence/absence of earthworms and straw return. Treatments included (1) control without earthworms and straw (E0S0); (2) treatment with only earthworms (E1S0); (3) treatment with only straw (E0S1); (4) treatment with both earthworms and straw. The Langmuir model was superior to the Freundlich mode provide a scientific basis for improving the utilization efficiency of soil P.The work concerns the study of the hydrochar from digestate and hydrochar co-compost characterization as amendments. The processes for hydrochar and co-compost production were described in Part 1 of this work (Scrinzi et al., 2022). selleck chemical The amendment properties of hydrochar (produced at 180-200-220 °C for 3 h) and co-composts (25%, 50%, and 75% hydrochar percentage of digestate substitution) were assessed by phytotoxicity, plant growth bioassay, and soil effect. Different seeds species (Lepidium sativum, Cucumis sativus, and Sorghum bicolor sp.) were dosed at increased concentrations using both wet raw amendments and their water extracts. The chemical characterization showed phytotoxic compounds content depending on both the initial feedstock (digestate) and the HTC process; at the same time, the analysis highlighted the reduction of these compounds by composting (organic acid, polyphenols, salt concentration). The dose-response was analyzed by the Cedergreen-Streibig-Ritz model and the half-maximal effective concentration (EC50) was calculated based on this equation. The soil properties and GHG emissions measurements (CH4, CO2, N2O, and NH3) highlighted the effect on N dynamics and on soil respiration induced by substrates. The HC200 soil application determined a significant impact on CO2 and N2O emission and NH3 volatilization (10.82 mol CO2/m2; 51.45 mmol N2O/m2; 112 mol NH3/m2) and a significant reduction of total N and TOC (46% of TKN and 49% of TOC). The co-compost (75%) showed specific effects after soil application compared to other samples an increase of available P (48%), a greater content of nitrogen (1626 mg/kg dry basis), and a reduction of organic carbon (17%). Our results demonstrate the good quality of co-compost and at the same time the validity of this post-treatment for addressing many issues related to hydrochar use in the soil as an amendment, confirming the suitability of HTC process integration for digestate treatment in anaerobic digestion plants.Bio-derived magnetic activated carbons from industrial chestnut shell waste have been obtained through a novel, optimized and sustainable methodology where impregnation, pyrolysis, acid washing or other intermediate steps commonly used in the activation process were eliminated saving time, energy and costs. The resulting materials (MACs) were obtained at 220-800 °C showed interesting properties textural (SBET up to 568 m2 g-1) and magnetic (different iron species developed), depending on the activation temperature employed. Data showed outstanding results when MACs were tested for Hg removal in pollution emissions at 150 °C in lab-scale device. In MACs obtained at 500-600 °C, where the highest concentration of magnetite was found, the best Hg adsorption capacity was achieved, while it decreased when metallic iron or iron carbides were present (MACs obtained at 800 °C). Moreover, the difference of Hg0 removal/adsorption in N2+O2 and Simulated Flue Gas atmosphere between MACs obtained at 500 and 600 °C pointed out the influence on Hg removal of additional parameters, as surface chemistry and the existence of sulfur or chloride. The determination of Hg species in post-retention solids confirmed the mercury oxidation by high-valence iron ions (Fe3+) and the involvement of physisorption and chemisorption processes for the gas-solid interaction mechanism.The colostrum quality (immunoglobulin content) is one of the most challenging aspects for hyperprolific sows in the modern pig industry. The objective of this study was to evaluate relationships among sow body condition scores, litter characteristics, and colostrum IgG content in hyperprolific sows, using a digital Brix refractometer to measure IgG. Samples (5 ml) were collected from two hundred and eighty-seven sows within the first hour postpartum. Sow parameters and back fat thickness at farrowing (BFF) and weaning (BFW) were recorded. The results indicate a positive correlation between parity and IgG, as well as BFF and BFW. A negative correlation was found between the number of weaning piglets and BFW. Moreover, a positive correlation was observed between the number of mummified piglets and colostrum IgG. Finally, lactation duration was positively associated with BFF. In conclusion, the number of mummified piglets is a factor positively associated with colostrum IgG content in hyperprolific sows.The present study was designed to establish a comprehensive and practical method for the quality evaluation and control of herbal preparation (HEP). The chemical information of belamcandae rhizoma antiviral injection (BRAI) was extracted using a dual-system control system comprised of HPLC chromatography and attenuated total reflection Fourier transform infrared (ATR-FT-IR) spectroscopy. To begin with, a quantitative analysis of six BRAI index components was accomplished. On this basis, HPLC five-wavelength fusion fingerprint was established to control the overall quality of BRAI. Secondly, the quality control system of ATR-FT-IR spectroscopy was constructed, that is, a quantitative analytic model to forecast the total amount of index components. Concurrently, the ATR-FT-IR quantized fingerprint was established for similarity analysis utilizing the Systematic quantified fingerprint method (SQFM). In addition, an integrated evaluation technique based on equal weights was presented to assure the comprehensiveness of chemical information. The 20 samples demonstrated good consistency in terms of quality, with a quality rating of grade 1-3. Notably, the rationality of the average method of Systematic quantified fingerprint method application in BRAI was further verified using PCA and low-level data fusion. Finally, this paper developed a model for intelligent analysis that is both quick and complete. We have redefined the quality standard of belamcandae rhizoma that can be put into production (70% less then Pm less then 130%) in light of the influence of other HEM in the BRAI. This research demonstrated a quality analysis technique based on chromatography and spectrum, which was suited for HEP consistency control since it was easy, quick, accurate, and reliable.Ivermectin (IVM) drug substance is a semi-synthetic macrocyclic lactone that exhibits a broad spectrum of activity and high potency towards endo- and ectoparasites. In this study, a comprehensive forced degradation study was carried out on IVM drug substance (under the conditions recommended in the ICH guidelines) to identify and characterize its major degradation products (DPs). IVM drug substance was subjected to acidic, alkaline, oxidation (H2O2 and K2Cr2O7), thermal (solid and solution state), and photolytic (solid and solution state) stress degradations. Chromatographic separation of the drug substance and its DPs was achieved using a gradient elution on a HALO C18 column (150 × 4.6 mm, 2.7 µm). A total of five major DPs were observed for IVM drug substance under various stressed conditions. Additionally, ivermectin API lots exhibited instability when stored under room temperature and at 45% relative humidity for two years. These DPs were identified and characterized using liquid chromatography-high resolution mass spectrometry (LC-HRMS) and a comparison of their fragmentation profile with IVM H2B1a using tandem mass spectrometry. Of these, H2O2 induced oxidative degradation product (3,4-epoxide H2B1a) was isolated using semi-preparative HPLC and its structure was elucidated comprehensively using LC-HRMS and nuclear magnetic resonance spectroscopy. The proposed structures of the DPs have been rationalized by appropriate degradation pathways of IVM H2B1a. Comprehensive degradation profile of IVM drug substance should facilitate the understanding of the stability profile of IVM drug substance, setting the specification of DPs in finished products as well as aid in the design of generic formulation made with IVM.
