Efficacy and Safety of Hydrodissection-based Capsulectomy for Improving Cervical Mobility and Appearance After Expanded Flap Transfer.

An expander capsule is a fibrous membrane that forms around an expander after tissue expansion. However, whether the capsule should be removed after the expander is removed remains controversial. The authors aimed to investigate the efficacy and safety of cervical capsulectomy for improving neck mobility and appearance after expanded flap transfer.

DNA Binding and Electrochemical Characterization of Oxidative Products of the Cobalt(II) Complex.

The synthesis of -tetrakis(3,4,5-trimethoxyphenyl)porphyrin [HT(3,4,5-OCH)PP] and cobalt(II) -tetrakis(3,4,5-trimethoxyphenyl)porphyrin [Co(T(3,4,5-OCH)PP)] has been successfully accomplished. The oxidation properties of [Co(T(3,4,5-OCH)PP)] have been assessed through UV-vis, NMR, and EPR techniques. It can be seen in the UV-vis spectrum that adding SbCl caused extra peaks to appear at 674 nm, which means that a π-cation radical was formed.

Attosecond All-Optical Retrieval of Valley Polarization via Circular Dichroism in Transient Absorption.

We propose a scheme for retrieving the ultrafast valley polarization (VP) dynamics in two-dimensional hexagonal materials via attosecond circular dichroism (CD) transient absorption spectroscopy. This approach builds on the CD transition between the first and higher conduction bands induced by the circularly polarized probe pulses. The population imbalance at nonequivalent valleys in the first conduction band is proportionally mapped onto the difference in absorption coefficients of two probe pulses with opposite helicities, supporting an unprecedented quantitative retrieval of the corresponding VP dynamics with subfemtosecond time resolution.

Living with temperature changes: Salicylic acid at the crossroads of plant immunity and temperature resilience.

Salicylic acid (SA) is a key defense hormone shaped by temperature. High temperatures suppress, while low temperatures enhance, SA biosynthesis and signaling, thereby influencing plant immunity and temperature resilience. This review synthesizes current understanding of how temperature modulates SA pathways and their cross-talk with other hormones to balance growth and defense.

Direct Evidence of Intrinsic Mott State and Its Layer-Parity Oscillation in a Breathing Kagome Crystal Down to Monolayer.

We report direct spectroscopic evidence of correlation-driven Mott states in layered Nb_{3}Cl_{8} through combining scanning tunneling microscopy (STM) and dynamical mean-field theory. The Hubbard bands persist down to monolayer, providing the definitive evidence for the Mottness in Nb_{3}Cl_{8}. While the size of the Mott gap remains almost constant across all layers, a striking layer-parity-dependent oscillation emerges in the local density of states (LDOS) between even (n=2, 4, 6) and odd layers (n=1, 3, 5), which arises from the dimerization and correlation modulation of the obstructed atomic states, respectively.
