This study was designed to investigate the application value of shape memory alloy embracing fixator in the treatment of proximal clavicle fracture. From April 2018 to October 2020, the fracture data of patients with proximal clavicle fractures treated with shape memory alloy embracing fixator were retrospectively analyzed, including 12 males and 8 females. The age of patients ranged from 34 to 66 years (mean, 43.4 years). According to Craig's classification, the patients were divided into the following groups: type C (eight cases), type C (five cases), type C (seven cases), all of which were closed fractures without nerve or vascular injury. The fracture healing time and postoperative complications were observed, and the shoulder joint function was evaluated by Constant score. All patients were followed up for 13-19 months (average 15.6 months). The clavicle radiographs showed that all the 20 patients had bone union, and the fracture union time was 6-10 months (average 7.2 months). There were no complications such as internal fixation fracture and displacement. According to the Constant criterion, 13 cases were excellent and 5 cases were fair and 1 case was good. The treatment of proximal clavicle fracture with shape memory alloy embracing fixator is an effective treatment method with simple operation with satisfactory fixation effect and low complication rate, which is worthy of being widely used in clinical practice.

This editorial celebrates the 80th birthday of Distinguished Professor Laszlo Zaborszky, co-founder of Brain Structure and Function, and reflects on his monumental contributions to neuroscience, particularly his pioneering work on the cholinergic basal forebrain. Professor Zaborszky's research has reshaped our understanding of this brain region's organization and function, uncovering its critical role in cognitive processes such as learning, memory, and attention. His findings have challenged longstanding assumptions, demonstrating that the cholinergic projections to the cortex are highly organized, with implications for neurodegenerative diseases like Alzheimer's.

Alzheimer's disease (AD) is a severe neurodegenerative disease, and the most common type of dementia, with symptoms of progressive cognitive dysfunction and behavioral impairment. Studying the pathogenesis of AD and exploring new targets for the prevention and treatment of AD is a very worthwhile challenge. Accumulating evidence has highlighted the effects of fatty acid metabolism on AD.

Traditional wound closure methods often present several issues, including additional puncture wounds, adverse effects from anesthesia, and noticeable scarring. Inspired by embryonic wound healing, a Janus hydrogel (PG/Au-Asp@PCM) is designed to manipulate non-invasive wound closure by photothermal-responsive self-contraction of PG/Au-Asp@PCM, which is attributed to the shape memory behavior of PG/Au-Asp@PCM under near-infrared (NIR). Wherein, gelatin acts as a thermally reversible "switch" and polyacrylamide creates stable and cross-linked "net-points".

Intraocular lenses (IOLs) play a pivotal role in restoring vision following cataract surgery. The evolution of polymeric biomaterials has been central to addressing challenges such as biocompatibility, optical clarity, mechanical stability, and resistance to opacification. This review explores essential requirements for IOL biomaterials, emphasizing their ability to mitigate complications like posterior capsule opacification (PCO) and dysphotopsias while maintaining long-term durability and visual quality.

Shape-memory materials are widely utilized in biomedical devices and tissue engineering, particularly for their ability to undergo predefined shape changes in response to external stimuli. In this study, a shape-transformable organohydrogel was developed by incorporating a gallium mesh into a polyacrylamide/alginate/glycerol matrix. The gallium mesh, which transitions between solid and liquid states at moderate temperatures (~29.
