Despite their regenerative ability, peripheral nerves cannot self-repair after severe defects. While nerve grafting is the gold standard for the treatment of PNIs, it is limited by graft versus host reactions, surgical complications, and limited donor nerves. As the field of material science continues to develop, hydrogels have been proposed for use in PNI repair after their biomodification, targeted modification, or loading with biological factors and cells. This article reviewed research advances in hydrogels used for PNI repair, including simple hydrogels and composite functionalized hydrogels loaded with biological factors and cells. Based on the findings from these reviews, we determined that further clarification of the mechanisms of action for hydrogels and loaded biological factors in modulating cellular functions is necessary. In addition, there is a need to further explore the synergistic effect of novel functionalized hydrogels with other biological, physical, or biochemical factors.

This can reduce the recognition accuracy of SSVEP brain–computer interfaces (BCIs). To address this problem, a variational mode decomposition–based filter bank canonical correlation analysis (VMD-FBCCA) algorithm is proposed, which integrates the adaptive characteristics of VMD and the training-free nature of the FBCCA algorithm. First, the EEG signal of each channel is transformed into intrinsic mode functions (IMFs) by the VMD algorithm, which extracts frequency components of the SSVEP from each IMF. Next, a particle swarm algorithm is employed to optimize the weights of the IMFs and reconstruct the EEG signals. This reconstruction selectively enhances the IMFs in the target SSVEP frequency band while suppressing interference from other bands. Finally, the reconstructed EEG is classified using FBCCA to decode the SSVEP-BCI signal. To evaluate its effectiveness, the proposed algorithm is tested on datasets from the BCI Competition.

While endovascular recanalization offers the potential for improved outcomes, it requires precise navigation and visualization of the vascular bed distal to the occluded segment to mitigate risks and enhance procedural success. This study introduces a novel technique that employs a dynamic real-time three-dimensional (3D) roadmap as a navigation tool during endovascular recanalization procedures for CIAO. This technique leverages advanced 3D rotational angiography and real-time fluoroscopic overlay to provide continuous, high-fidelity visualization of vascular anatomy without the need for repeated angiographic acquisitions or roadmap updates. By eliminating the need for recurrent angiograms to obtain optimal working projections after C-arm adjustments, the dynamic real-time 3D roadmap significantly improves procedural efficiency. This innovation substantially reduces radiation exposure, and contrast media volume, directly enhancing patient safety. Moreover, real-time guidance minimizes procedural complications, such as vessel perforation and dissection, ensuring a safer and more controlled recanalization process. The dynamic real-time 3D roadmap offers a safe, accurate, and efficient approach for navigating complex vascular anatomy, improving clinical outcomes in patients with CIAO while reducing procedural risks and resource utilization.</p>","PeriodicalId":94303,"journal":{"name":"Brain-X","volume":"2 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/brx2.70015","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143121130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional treatments for sciatica include pain medication, physical therapy, and surgery in severe cases. However, these approaches can be invasive and costly and may not provide long-term relief. Occupational therapy refers to the intentional and strategic application of various activities associated with daily life, work, education, and leisure to address functional impairments. Focusing on targeted exercises, manual techniques, and ergonomic modifications to alleviate symptoms and improve function, it offers a promising alternative to medical treatments. Occupational therapy interventions for sciatica can reduce pain, increase mobility, and enhance the overall quality of life. As an empowering approach, such techniques aid symptom management and functional independence. This article explores occupational therapy-based assessments, interventions, outcomes, progress tracking, pharmacotherapy, challenges owing to surgical approaches, and devices for sciatic pain rehabilitation, with assessments aimed at improving the overall quality of life for individuals affected by this condition.

A comprehensive search was conducted on PubMed and Scopus for studies related to ASL in individuals with COVID-19 or post-COVID-19 syndrome published between December 2019 and August 2024. Extracted data encompassed study characteristics, ASL protocols, cognitive assessments, and principal findings. The most consistent observation across studies was hypoperfusion detected in various brain regions, particularly within the frontal lobes, which may correlate with cognitive impairment and olfactory dysfunction. Additionally, some investigations reported hyperperfusion localized to the leptomeninges. These results may reflect underlying mechanisms such as hypoxic–ischemic injury, inflammation, vascular dysfunction, and neuronal damage attributable to COVID-19. In conclusion, ASL has emerged as a valuable tool for evaluating brain perfusion among patients affected by or recovering from COVID-19 since it offers critical insights into cerebral hemodynamics and metabolism.
