Ce, N codoped TiO2 nano-particles were fabricated through sol–gel strategy in the absence of water. Results revealed that Ce was not implanted into the lattice of TiO2 and existed as the forms of smallcluster CeO2 which uniformly diffused onto the surface or interstitial site of TiO2, while N dopants weresuccessfully incorporated into the structure of TiO2 by substituting the lattice oxygen atoms and existedas the forms of N–Ti–O bonds, thereby resulting in the formation of impurity level above the valenceband of TiO2 and enhancement of visible photocatalytic (PC) performance. The enhanced visible PCmechanism was discussed.

This study proposed a new curing agent consisting of slag and desulfurization gypsum industrialwaste to solidify Cr(VI)-contaminated soils and prevent its migration and bioaccumulation in the ecosphere. The curing agent dosage of 10 – 30% resulted in a Cr(VI) toxic leaching concentration, compressive strength, and hydraulic conductivity range of 0.118 – 5.824 mg/L, 2.70 – 10.22 MPa, and 1.70 × 109–1.37 × 106 cm/s, respectively. Following four dry and wet cycles, the dosage of the curing agent was found to be 20 – 30% to achieve minimum environmental safety requirements. Cr(VI) in the cured specimens mainly existed as CrO42, or acid salt, in which a portion was changed to Cr(III) during precipitation or directly was encased in the silica-alumina mesh structure. The adsorption capacity of hexavalent chrome on the outer of the hydration product groups was insignificant owing to the electronegativity. Hence, the Cr(VI) was solidified by hydrides such as C-S(A)-H and calcium alumina inclusions. Calcite, quartz, and several zeolite-like substances were also found to be colloidal in the pores to block Cr(VI).

Purpose This study aimed to explore the impact of ABL1–tyrosine kinase inhibitors (TKIs) adherence on the survival of chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) children and clarify the potential predictors of patients’ prognosis from TKIs intake practices.Materials and Methods Ninety newly diagnosed Ph+ ALL patients who received TKIs were enrolled. We collected the baseline characteristics and adverse events in all children; moreover, TKIs adherence was measured by an eight-item Morisky medication adherence scale (MMAS-8). Progression-free survival (PFS) and overall survival (OS) analysis were performed, and risk factors for PFS and OS were evaluated.Results Among all patients, 69 cases were regarded as adherers, while 21 were non-adherers. The median duration of TKIs interruption was significantly prolonged in the non-adherence group than in the adherence group (13 [0-101] vs. 56 [11-128], p < 0.001). Additionally, dose reduction occurred in 55.2% of non-adherers versus 23.0% of adherers (p=0.002). The PFS and OS in adherers were significantly higher versus non-adherers (p=0.020 and p=0.039). MMAS-8 score was an independent risk factor for PFS (p=0.010) and OS (p=0.031). Among non-adherers, the median OS was only 23.1% (4.2%-42%) in patients aged ≤ 10 years versus 54.4% (38.8%-70%) in adolescents. Most of the patients who experienced TKIs non-adherence suffered pancytopenia.Conclusion TKIs adherence during treatment significantly influenced the survival of pediatric Ph+ ALL patients, and non-adherers with age ≤ 10 years were more vulnerable to TKIs disruption. The cumulative TKIs dose should be especially emphasized to patients with age ≤ 10 years, which may result in an inferior achievement of relevant treatment milestones.
