Tetrakispyrazolylethene: Protonation-Induced Emission.

Tetrakispyrazolylethene () was synthesized from pyrazole and hexachloroethane through a one-step substitution reaction. The increase of emission was detected both in solid and aqueous THF solution, compared with that in anhydrous THF. While the former originates from the crystal packing, the latter is attributed to the protonation-induced emission, independent of aggregation, based on the optical measurement under varying concentrations and particle-size distribution analysis.

Hexakispyrazolylethane: New Strategy for Stabilization of Hexaarylethane.

Hexakis(4-trimethylsilylpyrazol-1-yl)ethane was synthesized by the oxidative dimerization of tris(4-trimethylsilylpyrazol-1-yl)methane. Single-crystal X-ray structural analysis of hexakis(4-trimethylsilylpyrazol-1-yl)ethane showed that the ethane C-C bond (1.623(4) Å) is shorter than that in hexaphenylethane (1.

Adult survivors of childhood-onset steroid-dependent and steroid-resistant nephrotic syndrome treated with cyclosporine: a long-term single-center experience.

Background: Although evidence has confirmed that cyclosporine (CS) is efficacious against childhood-onset steroid-dependent and steroid-resistant nephrotic syndrome (SD/SRNS), some patients may continue to relapse during adulthood. However, predictive factors for adult active disease and kidney complications, such as chronic kidney disease (CKD) and hypertension, in this cohort remain unknown.

Methods: We conducted a retrospective study on the long-term outcomes of 81 young adults with childhood-onset SD/SRNS treated with CS.

Effectiveness and safety of Tolvaptan in infants with congenital heart disease.

Background: Tolvaptan (TLV) is a selective vasopressin receptor 2 antagonist administered for congestive heart failure (CHF) after inadequate response to other diuretics. The effectiveness and safety of TLV have been evaluated well in adult patients. However, reports on its use in pediatric patients, especially infants, are scarce.
