Therefore, MW irradiation with Fe3O4@SiC ceramic foam could efficiently degrade the distribution of ARGs in the atmosphere. OBJECTIVES Tyrosine kinase inhibitors (TKIs) are first line treatment choices for patients with epidermal growth factor receptor (EGFR) mutated non-small cell lung cancer (NSCLC). However, responses vary among patients, therefore good biomarkers predicting better responses are required. https://www.selleckchem.com/products/bozitinib.html EGFR mutations are detected in the blood from patients as circulating tumour DNA (ctDNA). Studies have shown that clearing ctDNA during first line TKI treatment predicts outcomes for first and second generation TKI treatments. We aimed to investigate the effects on outcome measures of ctDNA clearing in subsequent treatment lines to treatment with the third generation TKI osimertinib. METHODS In total, 225 patients were included in a prospective, multicentre study, where consecutive blood samples were monitored for EGFR mutations during systemic treatment lines, using the Cobas® EGFR mutation test v2. This study focused on EGFR mutations in ctDNA of 82 systemically pre-treated patients receiving osimertinib. RESULTS Clearing all EGFR mutations from the blood after osimertinib treatment, significantly predicted progression-free survival, objective response rates and disease control rates. Primary sensitising EGFR mutations were found in ctDNA in 70 % of patients, and were accompanied by the T790 M mutation in nearly two thirds of cases. The T790 M mutation was cleared in all cases, while the accompanying sensitising mutations did not necessarily clear. However, T790 M clearing without simultaneously clearing of the primary sensitising mutation did not predict clinical responses. Neither the detection of T790 M before osimertinib treatment, nor the presence of EGFR mutations at the time of osimertinib initiation predicted clinical outcomes. CONCLUSION The clearing of EGFR mutations in ctDNA after osimertinib treatment initiation in patients with advanced NSCLC is useful as a positive predictor of clinical outcome. Selective binding of aqueous-phase amino acids to mineral surfaces is regarded as a plausible first step in oligopeptide formation on early Earth. To clarify the strength and underlying mechanism of amino acid binding to pyrite surfaces, we measured the unbinding (pull-off) force of ten amino acids and two oligo-peptides from water-pyrite interfaces using atomic force microscopy (AFM). The most probable unbinding force could be described by a linearly increasing function with the size of the amino acid and a characteristic offset. A good correlation was obtained between the most probable unbinding force and the residue volume, surface area and polarizability of samples suggesting at least a partial contribution of van der Waals (vdW) forces, especially the London dispersion force. These results are useful in analysis of adhesion phenomena of amino acids in the given environmental settings such as in this work. INTRODUCTION This study aimed to identify latent profiles based on familial ethnic socialization, peer discrimination, and school multicultural climate among biethnic adolescents in South Korea and to examine how the emerged profiles were related to their life satisfaction.We also examined how biethnic affirmation interacted with the profiles in predicting life satisfaction. METHODS Questionnaire data from the first wave of the Panel Survey of Korean Multicultural Youth Adjustment was used. The sample consisted of 358 biethnic adolescents in 5th and 6th grade in South Korea. The meanage was 11.41 years old. Approximately 60% of the participants were in 5th grade and 51.68% were girls. RESULTS The results of LPA showed that familial ethnic socialization, peer discrimination, and school multicultural climate formed two distinct profiles in the current sample. These profiles were characterized as contexts of high and low biethnic acceptance. Biethnic adolescents in the context of high biethnic acceptance were significantly more satisfied with their lives than those in the context of low biethnic acceptance.Further, the positive association between biethnic iaffirmation and life satisfaction was more pronounced among adolescents in the context of low biethnic acceptance. CONCLUSIONS Findings suggest the importance of promoting biethnic acceptance across family, peer, and school settings for adolescents' biethnic affirmation and life satisfaction. Cold stress is one of the most common unfavorable environmental factors affecting the growth, development, and survival of plants. The DEAD-box RNA helicases play important roles in all types of processes of RNA metabolism. However, the function of DEAD-box RNA helicase under cold stress is poorly explored in plants, especially in rice. This study reported the identification of a novel rice thermo-sensitive chlorophyll-deficient mutant, tcd33, which displayed an albino phenotype before the four-leaf stage, then withered and eventually died at 20 °C, while wild-type plants exhibited normal green coloration at 32 °C. The tcd33 seedlings also exhibited less chlorophyll contents and severe defects of chloroplast structure under 20 °C condition. Map-based cloning and complementation experiments suggested that TCD33 encodes a chloroplast-located DEAD-box RNA helicase protein. The transcript expression level of TCD33 indicated that the genes related to chlorophyll (Chl) biosynthesis, photosynthesis, and chloroplast development in tcd33 mutants were down-regulated at 20 °C, while the down-regulated genes were nearly recovered to or slightly higher than the WT level at 32 °C. Together, our results suggest that the cold-inducible TCD33 is essential for early chloroplast development and is important for cold-responsive gene regulation and cold tolerance in rice. Probing the dynamic magnetic domain of permanent magnet materials under an external AC magnetic field using magnetic force microscopy is challenging as well as important to reveal their pinning sites and local magnetization processes. In this work, we develop alternating magnetic force microscopy (A-MFM) with a Co-GdOx superparamagnetic tip for observing the dynamic magnetic domain wall (DW) motion in a, b plane Nd-Fe-B sintered magnets by stimulating the magnetization of the superparamagnetic tip and Nd-Fe-B sample using an external AC magnetic field. This method enables the simultaneous measurement of DC and AC magnetic fields from the sample surface. The measurement results reveal that the DW motion does not happen until the amplitude of the external AC magnetic field reached 77 Oe0-p (zero to peak). Further increasing the external AC magnetic field strength leads to DW motion with larger movement area and stronger AC magnetic field originating from the DW motion. In addition, A-MFM images shows the pinning sites of the DW motion.
