作者： Kou Takahashi Ryotaro Miyazaki Daisuke Nakane Temitayo O. Aiyelabola Takashiro Akitsu Department of Chemistry Faculty of Science Tokyo University of Science Tokyo Japan Department of Chemistry Faculty of Science Obafemi Awolowo University Ile-Ife Nigeria

Hydrophobic Val derivative Schiff base copper(II) complexes and dipeptide (AlaAla, GlyGly) derivative Schiff base copper(II) complexes were introduced into egg white lysozyme. X-ray crystal structure analysis revealed amino acid derivative Schiff base copper(II) complexes were obtained. Herein we discuss primarily on the binding mode of copper(II) of the complexes obtained with egg white lysozyme. The electron density of copper(II) ions was confirmed by X-ray crystal structure analysis. The Val derivative Schiff base copper(II) complex was weakly bound at Arg114 of egg white lysozyme. In other copper(II) complexes, binding of copper(II) ions with dissociated ligands to various residues was observed. The binding sites of copper(II) ions were compared with computational scientific predictions.

Association of Hypertension and Plant-based Dietary Patterns on Cognitive Impairment: A Nationwide Cohort Study in China

This study investigated the association of hypertension with cognitive impairment and determined whether better adherence to plant-based diet (PBD) patterns may modify the association. We analyzed 4485 elderly individuals with normal cognition at baseline from the Chinese Longitudinal Healthy Longevity Survey (2011-2018). Cognitive function was assessed by the Mini-mental State Examination (MMSE)， and cognitive impairment was defined as an MMSE score below 18 points. Diet patterns were assessed using the overall plant-based diet index (PDI)， healthful plant-based diet index (hPDI)， and unhealthful plant-based diet index (uPDI) derived from a simplified food frequency questionnaire (FFQ). Blood pressure was measured through physical examination. Cox proportional hazard regression and restricted cubic spline were performed. Participants with hypertension had an increased risk of cognitive impairment compared with normal group. The associations between hypertension and cognitive impairment were more pronounced among participants with lower PDI than those with higher PDI， among participants with lower hPDI than those with higher hPDI， and among participants with higher uPDI than those with lower uPDI. A healthful PBD pattern may attenuate hypertension-induced cognitive impairment， while an unhealthful PBD pattern may exacerbate hypertension-induced cognitive impairment in elderly. Adherence to healthful PBD pattern could be used to prevent or mitigate adverse neurological effects in the hypertensive population.

Nickel-manganese binary layered oxides with high working potential and low cost are potential candidates for sodium-ion batteries,but their electrochemical properties are highly related to compositional *** composite materials with various phase structures of P3,P2/P3,P2,P2/O3,and P2/P3/O3 were synthesized by manipulating the sodium content and calcination conditions,leading to the construction of a synthetic phase diagram for Na_(x)Ni_(0.25)Mn_(0.75)O_(2)(0.45≤x≤1.1).Then,we compared the electrochemical characteristics and structural evolution during the desodiation/sodiation process of P2,P2/P3,P2/03,and P2/P3/O3-Na_(x)Ni_(0.25)Mn_(0.75)O_(2).Among them,P2/P3-Na0.75Ni0.25Mn0.75O2exhibits the best rate capability of 90.9 mA h g^(-1)at 5 C,with an initial discharge capacity of 142.62 mA h g^(-1)at 0.1 C and a capacity retention rate of 78.25%after 100 cycles at 1 C in the voltage range of 2-4.3 *** observed superior sodium storage performance of P2/P3 hybrids compared to other composite phases can be attributed to the enhanced Na^(+)transfer dynamic,reduction of the Jahn-teller effect,and improved reaction reversibility induced by the synergistic effect of P2 and P3 *** systematic research and exploration of phases in Na_(x)Ni_(0.25)Mn_(0.75)O_(2)provide new sights into high-performance nickel-manganese binary layered oxide for sodium-ion batteries.
