Clinical Efficacy of Three-Dimensional-Printed Pure Titanium Fracture Plates with Locking Screw Systems in Distal Tibia Fractures.

Distal tibia fractures are high-energy injuries characterized by a mismatch between standard plate designs and the patient's specific anatomical bone structure, which can lead to severe soft tissue damage. Recent advancements have focused on the development of customized metal plates using three-dimensional (3D) printing technology. However, 3D-printed metal plates using titanium alloys have not incorporated a locking system due to the brittleness of these alloys.

Machine learning prediction of in-hospital mortality and external validation in patients with cardiogenic shock: the RESCUE score.

Introduction And Objectives: Despite advances in mechanical circulatory support, mortality rates in cardiogenic shock (CS) remain high. A reliable risk stratification system could serve as a valuable guide in the clinical management of patients with CS. This study aimed to develop and externally validate a risk prediction model for in-hospital mortality in CS patients using machine learning (ML) algorithms.

Hematologic and clinical chemistry reference intervals for six species of wild birds frequently rescued in the Republic of Korea.

Objective: Reference intervals for hematologic and clinical chemistry values are useful when diagnosing a pathologic condition in animals. This study establishes relevant reference intervals for six species of wild birds that are frequently rescued at wildlife rescue centers in the Republic of Korea.

Methods: Forty-two Eurasian eagle owls (), 34 Oriental turtle doves (), 73 domestic pigeons (), 27 brown hawk-owls (), 76 common kestrels (), and 25 Eurasian magpies () were included in this study.

Engineering Spin Interaction Channels of FePc on Au(111).

We demonstrate the reversible control of interactions between a local molecular spin, hosted within an iron phthalocyanine (FePc) molecule, and the conduction electrons of a supporting Au(111) surface. Using the tip of a scanning tunneling microscope, we deliberately and reversibly manipulate the adsorption configuration of the molecule relative to the underlying substrate lattice. Different rotation configurations lead to noticeable changes in the differential conductance measured on the FePc molecules.

Recent advances in electrochemical copper catalysis for modern organic synthesis.

In recent decades, organic electrosynthesis has emerged as a practical, sustainable, and efficient approach that facilitates valuable transformations in synthetic chemistry. Combining electrochemistry with transition-metal catalysis is a promising and rapidly growing methodology for effectively forming challenging C-C and C-heteroatom bonds in complex molecules in a sustainable manner. In this review, we summarize the recent advances in the combination of electrochemistry and copper catalysis for various organic transformations.
