Variations exist in the manual preparationand delivery of cement during primary total hip arthroplasty. The incorporation of a power source may standardize cement mantle manufacturing. This study prospectively compared the use of a new power-operated polymethylmethacrylate vacuum mixing and delivery system to a commonly used manually powered industry standard. The study did not reveal a significant difference in the quality of cement mantle grades when comparing the use of this power-operated system to an industry standard manual system. However, the benefit of the new preparation and delivery system may be in consistent porosity reduction and not in the improvement of cement mantle grading.

The current unavailability of efficient myocardial repair therapies constitutes a significant bottleneck in the clinical management of myocardial infarction (MI). Ginsenoside Rb1 (GRb1) has emerged as a compound with potential benefits in safeguarding myocardial cells and facilitating the regeneration of myocardial tissue. However, its efficacy in treating MI-related ischemic conditions is hampered by its low bioavailability and inadequate angiogenic properties.

Abdominal hernia repair is a common surgical procedure, involving in most cases the use of textile meshes providing a mechanical barrier to consolidate the damaged surrounding tissues and prevent the resurgence of the hernia. However, in more than half cases postoperative complications such as adhesions and infections occur at the surface of the mesh, leading to chronic pain for the patient and requiring the removal of the implant. One of the most promising strategies to reduce the risk of postoperative adhesions and infections is to add a physical barrier between the mesh and the abdominal walls.

Ocular surface chemical injuries often result in permanent visual impairment and necessitate complex, long-term treatments. Immediate and extensive irrigation serves as the first-line intervention, followed by various therapeutic protocols applied throughout different stages of the condition. To optimize outcomes, conventional regimens increasingly incorporate biological agents and surgical techniques.

Mobile Ad Hoc Networks (MANETs) are increasingly replacing conventional communication systems due to their decentralized and dynamic nature. However, their wireless architecture makes them highly vulnerable to flooding attacks, which can disrupt communication, deplete energy resources, and degrade network performance. This study presents a novel hybrid deep learning approach integrating Convolutional Neural Networks (CNN) with Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU) architectures to effectively detect and mitigate flooding attacks in MANETs.

Prime Editing can rewrite genes in living cells by allowing point mutations, deletions, or insertion of small DNA sequences with high precision. However, its safe and efficient delivery into human stem cells remains a technical challenge. In this report, we engineer Nanoscribes, virus-like particles that encapsidate ribonucleoprotein complexes of the Prime Editing system and allow their delivery into recipient cells.
