Article Synopsis
- This study examined the link between high-risk characteristics of carotid plaques, identified through high-resolution MRI, and clinical risk factors associated with acute cerebral infarction (ACI).
- Forty-five patients with vulnerable carotid plaques were analyzed, comparing those with ACI to those without, focusing on clinical factors and plaque phenotype occurrences.
- Findings indicated that hypertension significantly correlated with ACI, and patients with ACI had larger plaque volumes and higher occurrences of specific high-risk plaque characteristics like LRNC, IPH, and ulceration.
A revised reaction mechanism of CF3I synthesis catalyzed by activated carbon is investigated with quantum chemistry methods using density functional theory (DFT). The adsorption configurations of possible intermediates are carefully examined. The reaction pathway and related transition states are also analyzed.

The synthesis and spectral characterization of a schiff base, 2-pyridinecarbaldehyde-p-phenylenedihydrazone (short for 2PC-PPH), were described. It was found that ferric ion (Fe(3+)) could selectively quench the fluorescence of 2PC-PPH, whereas many other metal ions, such as Mn(2+), Zn(2+), Cu(2+), K(+), Al(3+), Ca(2+), Ni(2+), Co(2+), Cr(3+) and Fe(2+), could not quench its fluorescence. Based on this, a sensitive method for ferric ion selective detection was established.

- - The study explored the fluorescence properties of a system involving prulifloxacin (PUFX) and aluminum ions (Al(III)), finding that the presence of Al(III) significantly increased the fluorescence intensity when combined with sodium dodecylbenzene sulphonate (SDBS).
- - A new sensitive method using spectrofluorimetry was developed for measuring prulifloxacin concentrations, showing a strong linear relationship between enhanced fluorescence at 412 nm and prulifloxacin concentration ranging from 4.0 x 10(-8) to 3.0 x 10(-6) mol/L.
- - The method demonstrated a high correlation coefficient of 0.99901 and a low detection limit of 2
