119 patients were enrolled in a double-blind randomized parallel study versus placebo carried out to assess both the efficacy and tolerability of L-deprenyl (10 mg/day) for treatment of patients with ...organic mental disorders of the Alzheimer type (DAT). The treatments were given for 3 months, starting after a run-in period of 15 days to evaluate efficacy. A complete neuropsychological battery was administered monthly after the start of treatment whereas tolerability was assessed by checking, recording and classifying all the unfavorable experiences occurring. According to the results, L-deprenyl would seem to be a useful and reliable tool for the treatment of DAT patients in an attempt to improve their cognitive functions and reduce behavioral alterations, without frequent or severe side effects.

The singly Cabibbo-suppressed decay Λ_{c}^{+}→nπ^{+} is observed for the first time with a statistical significance of 7.3σ by using 3.9 fb^{-1} of e^{+}e^{-} collision data collected at ...center-of-mass energies between 4.612 and 4.699 GeV with the BESIII detector at BEPCII. The branching fraction of Λ_{c}^{+}→nπ^{+} is measured to be (6.6±1.2_{stat}±0.4_{syst})×10^{-4}. By taking the upper limit of branching fractions of Λ_{c}^{+}→pπ^{0} from the Belle experiment, the ratio of branching fractions between Λ_{c}^{+}→nπ^{+} and Λ_{c}^{+}→pπ^{0} is calculated to be larger than 7.2 at the 90% confidence level, which disagrees with most predictions of the available phenomenological models. In addition, the branching fractions of the Cabibbo-favored decays Λ_{c}^{+}→Λπ^{+} and Λ_{c}^{+}→Σ^{0}π^{+} are measured to be (1.31±0.08_{stat}±0.05_{syst})×10^{-2} and (1.22±0.08_{stat}±0.07_{syst})×10^{-2}, respectively, which are consistent with previous results.
