Background: Because of clinically overlapping parkinsonian motor symptoms, it is hard to diagnose a specific disease in atypical parkinsonism or differentiate Parkinson's disease (PD) from atypical parkinsonism. Herein, we report the clinicopathological mismatching of an autopsy-confirmed PSP in a patient clinically diagnosed with PD.
Method Clinical History: We reviewed the brief clinical history of a 70-year-old man and neurologic examination.

Interstitial quasi-atomic electrons (IQEs) in the quantized energy levels of positively charged cavities possess a substantial own magnetic moment and control the magnetism of crystalline electrides depending on the interaction with surrounding cations. However, weak spin-orbit coupling and gentle exchange interaction restricted by the IQEs preclude a large magnetic anisotropic, remaining a challenge for a hard magnetism. It is reported that 2D [ReC]·2e electrides (Re = Er, Ho, Dy, and Tb) show the permanent magnetism in a ferrimagnetic ground state, mimicking the ferrites composed of magnetic sublattices with different spin polarizations.

Purepose: The intraoperative femtosecond laser time, Cumulative Dissipated Energy (CDE), Effective Phacoemulsification time (EPT), and intraoperative fluid perfusion volume were compared under different model fragmentation modes using Catalys femtosecond laser system.
Methods: This was a single-center, prospective, randomized controlled study. A total of 120 eyes who underwent femtosecond laser-assisted cataract phacoemulsification combined with intraocular lens implantation in Xiamen Eye Center affiliated to Xiamen University from September 2022 to March 2023 were randomly divided into 4 groups to undergo pre-nucleus splitting in different ways: Group 1: six-split, Group 2: eight-split, Group 3: six-split + gridded softening, and Group 4: eight-split + gridded softening.

Resolving the order of speciation events that occurred in rapid succession is inherently hard and typically requires a phylogenomic approach. A case in point concerns the previously unresolved phylogeny of the three species of banded newt (genus Ommatotriton). We obtain c.
