Disproportionation-induced solid-state fluorescence in 6,13-dihydropentacenes.

The thermally and photolytically induced disproportionation of 6,13-dihydropentacene derivatives into tetrahydropentacenes and pentacenes results in unique solid-state fluorescence. The fluorescence thereby depends on the molecular structure and the molecular arrangement in the solid state.

[A comparative study assessing clinical effects of naftopidil and tamsulosin hydrochloride on benign prostatic hyperplasia with overactive bladder].

Purpose: We compared the efficacy of naftopidil with that of tamsulosin hydrochloride for 154 symptomatic benign prostatic hyperplasia (BPH) patients who also suffered from overactive bladder (OAB) symptoms.

Materials And Methods: Naftopidil and tamsulosin hydrochloride were administered for eight weeks. The international prostate symptom score (IPSS), QOL index, maximum flow rate (Q(max)), residual urine volume (RUV) and side effect profile were determined before the administration and after eight weeks of treatment.
