The aim of the present study is to assess the results of indirect reduction and hybrid external fixation in management of comminuted tibial plateau fractures. The study included 28 patients with high-energy tibial plateau fractures (Schatzker type V and VI). The ages ranged from 22 to 58 years with an average of 35 years. The trauma was a road traffic accident in 16 cases and a fall from a height in 12 cases. Concomitant soft tissue injuries were present in 18 cases such as skin wounds in 6 cases, excessive swelling with skin blisters in 9 cases, and compartment syndrome in 3 cases. After clinical and radiological evaluation all the patients were treated by indirect reduction using a traction table and a hybrid external fixator. The average time to healing was 3.2 months. At the final follow-up the range of knee movement ranged from 0 degrees-140 degrees with an average of 110 degrees. The results were satisfactory in 23 cases and unsatisfactory in 5 cases according to the Rasmussen knee functional score. Complications included pin tract infection in 12 cases, an extension lag in 2 cases, varus deformity of about 15 degrees in one case, deep infection in one case and early osteoarthritic changes in 2 cases. Hybrid external fixation is a good method for treatment of comminuted tibial plateau fractures. It allows for early joint movement and reduces the risk of serious complications.

Objective: Among all BCI paradigms, motion imagery (MI) has gained favor among researchers because it allows users to control external devices by imagining movements rather than actually performing actions. This property holds important promise for clinical applications, especially in areas such as stroke rehabilitation. Electroencephalogram (EEG) signals and functional near-infrared spectroscopy (fNIRS) signals are two of the more popular neuroimaging techniques for obtaining MI signals from the brain.

Hybrid magnonics has attracted extensive attention for its potential applications in quantum information processing, especially following the discovery of strong coupling in magnon-magnon hybrid systems. In this paper, we studied the coupling phenomena between the left-handed (LH) and right-handed (RH) magnon modes in synthetic antiferromagnets (SAFs) with a tilted perpendicular magnetic anisotropy (PMA). By tilting the PMA at a certain angle from the film normal, we achieved strong magnon-magnon coupling without the need for an external magnetic field.

Hybrid nano-sized motors with navigation and self-actuation capabilities have emerged as promising nanocarriers for a wide range of delivery, sensing, and diagnostic applications due to their unique ability to achieve controllable locomotion within a complex biological environment such as tissue. However, most current nanomotors typically operate using a single driving mode, whereas propulsion induced by both external and local stimuli could be more beneficial to achieve efficient motility in a biomedical setting. In this work, we present a hybrid nanomotor by functionalizing biodegradable stomatocytes with platinum nanoparticles (Pt NPs).

In this study, a novel hybrid nanostructure consisting of acid-decorated chitosan and magnetic AlFeO nanoparticles was fabricated. The acid-decorated chitosan provided a stable and biocompatible matrix for the magnetic AlFeO nanoparticles. Various techniques including Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction patterns (XRD), thermogravimetric analysis (TGA), vibrating sample magnetometry (VSM), specific surface area (BET), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS) were used to characterize and confirm the successful synthesis of the hybrid nanostructure.

Objective: Both the en bloc island technique and the branched graft technique (BGT) present advantages but also limitations in aortic arch surgery. Here is the first presentation of an innovative prosthesis for aortic arch replacement, conceived to overcome the disadvantages of both techniques.
Methods: The novel ISLAND graft is a tubular Dacron or hybrid prosthesis with an additional extended Dacron graft ("bubble") on the superior aspect, for en bloc island graft anastomosis.
