Core-shell silicon/multiwall carbon nanotubes are one of the most promising anode candidates for further improvement of lithium-ion batteries. Sufficient accommodation for massive volume expansion of silicon during the lithiation process and preventing pulverization and delamination with easy fabrication processes are still critical issues for practical applications. In this study, core-shell silicon/MWCNTs anode materials were synthesized using a facile and controllable PECVD technique to realize aligned MWCNTs followed by a silicon sputtering step.

Cardiomyocytes can be implanted to remuscularize the failing heart. Challenges include sufficient cardiomyocyte retention for a sustainable therapeutic impact without intolerable side effects, such as arrhythmia and tumour growth. We investigated the hypothesis that epicardial engineered heart muscle (EHM) allografts from induced pluripotent stem cell-derived cardiomyocytes and stromal cells structurally and functionally remuscularize the chronically failing heart without limiting side effects in rhesus macaques.

Background/aims: To report the long-term visual outcomes and side effects in patients with small choroidal melanoma (CM) undergoing ruthenium-106 (Ru-106) plaque brachytherapy.
Methods: Retrospective, interventional, consecutive series of small CM ≤2.5 mm in height and ≤16 mm in largest basal diameter treated with Ru-106 plaque with a median radiation dose of 100 Gy prescribed to tumour apical height.
Long-term retention of the pedicled thymic flap after bronchial stump coverage.

This study aimed to assess the feasibility and retention rates of pedicled thymic flaps to enhance understanding of bronchial stump coverage. A retrospective analysis of 22 consecutive patients who underwent anatomical lung resection followed by bronchial stump coverage with pedicled thymic flaps between January 2017 and December 2022 was conducted. The procedure was performed using a minimally invasive 3-port video-assisted thoracoscopic surgery technique for all patients with no complications related to graft harvest or fixation.

Osteoarthritis is the most prevalent form of arthritis, and a leading cause of pain and long-term disability. Dysregulation of redox homeostasis is a key feature in the pathological progression of osteoarthritis that amplifies the inflammatory response, aggravates synovitis and accelerates cartilage degradation. Herein, a hemin and chitosan-mediated antioxidant gel inducing ROS conversion (hc-MAGIC) was constructed to targeting oxidative stress for osteoarthritis treatment.
