A series of [C₆₀/C₇₀] fullerene derivatives containing different spirobifluorene and tri-Ph imidazole were synthesized and confirmed by IR, ¹H NMR, ¹³C NMR, MALDI-TOF-MS. Their optical limiting properties were investigated by nanosecond and femtosecond laser systems. Results showed that fullerene derivatives exhibited high optical limiting properties. Lower OL thresholds of 13.7, 14.9, 15.3, 23.3, and 24.0 J/cm² were observed for C₇₀-SBF, C₆₀-TPI, C₆₀-SBF, C₆₀-FSBF, and C₆₀-BTPI resp. with the linear transmittance of 75%, which implied that these optical limiting properties increased with the degree of conjugation and electron-donating or electron-accepting abilities of donors or acceptors in donor-acceptor (D-A) structures. The strong D and A with large conjugation is an effective way to enhance OL properties.

Cooperative binding and stepwise encapsulation of drug molecules by sulfonylcalixarene-based metal-organic supercontainers was written by Sheng, Tian-Pu;Fan, Xin-Xia;Zheng, Guo-Zong;Dai, Feng-Rong;Chen, Zhong-Ning. And the article was included in Molecules in 2020.Related Products of 117976-90-6 The following contents are mentioned in the article:

The cooperative binding behavior of a face-directed octahedral metal-organic supercontainer featuring one endo cavity and six exo cavities was thoroughly examined in chloroform solution through UV-visible (UV-Vis) titration technique using two representative drug mols. as the guests. The titration curves and their nonlinear fit to Hill equation strongly suggest the efficient encapsulation of the guest mols. by the synthetic host, which exhibit interesting cooperative and stepwise binding behavior. Based on the control experiments using tetranuclear complex as a reference, it is clear that two equivalent of the guest mols. are initially encapsulated inside the endo cavity, followed by the trapping of six addnl. equivalent of the drug mols. through six exo cavities (1 equivalent per exo cavity), and the remaining guests are entrapped by the external pockets. The results provide an in-depth understanding of the cooperative binding behavior of metal-organic supercontainers, which opens up new opportunities for designing synthetic receptors for truly biomimetic functional applications.

The methods determine each drug through the estimation of its sodium content, using Flame Atomic Absorption Spectroscopy at wavelength 589 nm. Central laboratory at Faculty of Pharmacy, Damanhour University. Time duration Jan.-March, 2020. Methods are developed and optimized for maximum sensitivity, selectivity and degree of greenness. Linearity is achieved in the range of 8.29-66.33 ppm of Rabeprazole sodium (equivalent to 0.5-4 ppm Na) and 14.13-141.32 ppm of Fluvastatin sodium (equivalent to 0.75 -7.5 ppm Na).

Both complexes 1 and 2 displayed 2-dimensional (4,4) grid layers containing 1-dimensional metal-carboxylate chains. Thermogravimetric Analyses (TGA), powder x-ray diffractions (PXRD) and fluorescence properties for compounds 1 and 2 were also studied. The solid state fluorescence spectra indicated that the emission spectrum of complex 1 showed obvious blue shift (-78 nm) compared to free bip co-ligand due to the ligand-to-metal charge-transfer (LMCT) effect. The compound 2 showed similar emission spectrum to the free bpe ligand, but the slight red shift might be attributed to the complexation effect between the bpe mol. and Zn atoms.

Patients with hematol. malignancies are at increased risk of severe COVID-19 outcomes due to compromised immune responses, but the insights of these studies have been compromised due to intrinsic limitations in study design. We present the PROSECO prospective observational study (NCT04858568) on 457 patients with lymphoma that received 2 or 3 COVID-19 vaccine doses. We show undetectable humoral responses following 2 vaccine doses in 52% of patients undergoing active anticancer treatment. Moreover, 60% of patients on anti-CD20 therapy had undetectable antibodies following full vaccination within 12 mo of receiving their anticancer therapy. However, 70% of individuals with indolent B-cell lymphoma displayed improved antibody responses following booster vaccination. Notably, 63% of all patients displayed antigen-specific T-cell responses, which increased after a 3rd dose irresp. of their cancer treatment status. Our results emphasize the urgency of careful monitoring of COVID-19-specific immune responses to guide vaccination schemes in these vulnerable populations.

Management of patients with chronic lymphocytic leukemia (CLL) is changing due to considerable advances in the therapeutic armamentarium, and new therapies will possibly continue to emerge in the near future. Therefore, the CLL working group of the Dutch-Belgium Haemato-Oncol. Cooperative Group for Adults in the Netherlands (HOVON) necessitated revising the Dutch CLL guidelines. The current guideline is based on the expert opinion of the HOVON CLL working group members and focusses on well-designed clin. trials taking into account efficacy with special emphasis on toxicity, treatment duration and treatment intensity. This article provides recommendations on diagnosis, treatment strategies in front-line and relapsed setting and provides supportive care measurements during novel-based therapies as well as for infectious CLL-related complications.

Estimation of the viscosity of ionic liquids at room temperature using volumetric connectivity index was written by Xiong, Yan;Ding, Jing;Yu, Dahong. And the article was included in Jisuanji Yu Yingyong Huaxue in 2012.Electric Literature of C8H15F6N2P The following contents are mentioned in the article:

Ionic Liquids (ILs) have been considered as good green replacements for conventional volatile organic solvents due to their unique environment-friendly characteristics. Viscosity data as one of the most important thermodn. data needed for solvents are still in the scarcity for ILs. Although a large amount of exptl. data have been measured and reported, some appropriate theor. models that are crucial for the design and optimization of chem. processes are required to correlate and predict thermodn. properties. In recent years, many efforts including group contribution and connectivity index were attributed to develop thermodn. models to estimate the viscosity of ILs. In this article, a new approach named volumetric connectivity index (VCI) based on the phys. observable volume of groups and the concept of mol. connectivity index was proposed for the prediction of the viscosity of ILs. Viscosities at room temperature of 90 pure ILs were estimated by this new model and the average devation was only 5.95%, R² and rmsd were 0.9905 and 21cP, resp.
