One-stage operation for rare multiple mirror intracranial aneurysms: a case report and literature review.

Although intracranial multiple aneurysms are not uncommon, multiple mirror aneurysms are relatively rare. A few isolated cases have been described. However, to the best of our knowledge, 3 pairs of pure symmetrical mirror aneurysms in one patient have not been reported yet.

Simultaneous determination of valproic acid and 2-propyl-4-pentenoic acid for the prediction of clinical adverse effects in Chinese patients with epilepsy.

Valproic acid (VPA) is a well-established anticonvulsant drug that has been increasingly used in the treatment of many forms of generalized epilepsy. Although there are many reports of adverse effects of VPA, studies focusing on the concentration-response relationships of VPA and its metabolites in patients with epilepsy are extremely limited. In this study, a rapid and specific high performance liquid chromatography-ultraviolet (HPLC-UV) method to simultaneously detect the concentrations of VPA and its major hepatotoxic metabolite 2-propyl-4-pentenoic acid (4-ene VPA) in human plasma has been established, using 2,4'-dibromoacetophenone and octanoic acid as the derivatization reagent and internal standard, respectively.

QSPR modeling of n-octanol/water partition coefficients and water solubility of PCDEs by the method of Cl substitution position.

The number of Cl substitution positions (N(PCS)) of all 209 possible molecular structure patterns of polychlorinated diphenyl ethers (PCDEs) were correlated with their partition properties n-octanol/water partition coefficient (lgK(ow)) and sub-cooled liquid water solubilities (-lgS(w,l)). The correlation coefficients (R) and the leave-one-out (LOO) cross-validation correlation coefficients (R(cv)) of all the 6-descriptor models for lgK(ow) and -lgS(w,l) are more than 0.98.
