Two series of isostructural lanthanide coordination complexes, namely, LIFM-42(Ln), Ln = Eu, Tb, Gd, and LIFM-43(Ln), Ln = Er, Yb) were synthesized through the self-assembly of an ESIPT (excited-state intramolecular proton transfer) ligand, H2hpi2cf (5-(2-(5-fluoro-2-hydroxyphenyl)-4,5-bis(4-fluorophenyl)-1H-imidazol-1-yl)isophthalic acid) with different lanthanide ions. In the coordination structures linked by the ligands and oxo-bridged LnIII2 clusters (for LIFM-42(Ln) series) or isolated LnIII ions (for LIFM-43(Ln) series), the ESIPT ligand can serve as both the host and antenna for protecting and sensitizing the photoluminescence (PL) of LnIII ions...

The purpose of the study was to predict young children's shyness from both internal/biological (i.e., resting respiratory sinus arrhythmia; RSA) and external (i.e., neighborhood quality) factors. Participants were 180 children at 42 (Time 1; T1), 72 (T2), and 84 (T3) months of age. RSA data were obtained at T1 during a neutral film in the laboratory. Mothers reported perceived neighborhood quality at T2 and children's dispositional shyness at T1 and T3. Path analyses indicated that resting RSA interacted with neighborhood quality to predict T3 shyness, even after controlling for earlier family income and T1 shyness...

Ulceration is a serious consequence of diabetes that can lead to disability in patients with diabetes. One of the risk factors for ulceration is high foot pressure. The thickness of the pedal soft tissue is important because it has a cushioning effect. Soft tissue atrophy causes elevation in the plantar pressure, which, in turn, causes ischemia. Therefore, we investigated the severity of pedal soft tissue atrophy caused by diabetes and aging. From February 2009 to February 2016, we examined the feet of 261 patients treated in our hospital using magnetic resonance imaging...

Huaguo Chen, Xin Zhou, Baoan Song
Dufulin is a plant antiviral agent with a novel molecular structure and has been used widely to prevent and control tobacco and rice viral diseases. In this study, an UHPLC-MS/MS assay was developed for rapid determination of dufulin racemate (rac-DFL) and its R (S)-enantiomers in rat plasma, tissues, urine and feces. A MALDI-MSI method was further used to visual research on tissue distribution after oral administration of the three analytes. Toxicokinetic study showed that both (R)-enantiomers of dufulin ((R)-DFL) and (S)-enantiomers of dufulin ((S)-DFL) had a faster ability to reach Cmax than that of rac-DFL...
