DL has been applied to detect free fluid on Focused Assessment with Sonography for Trauma (FAST), traumatic findings on chest and pelvic X-rays, and computed tomography (CT) scans, identify intracranial hemorrhage on head CT, detect vertebral fractures, and identify injuries to organs like the spleen, liver, and lungs on abdominal and chest CT. Future directions involve expanding dataset size and diversity through federated learning, enhancing model explainability and transparency to build clinician trust, and integrating multimodal data to provide more meaningful insights into traumatic injuries. Though some commercial artificial intelligence products are Food and Drug Administration-approved for clinical use in the trauma field, adoption remains limited, highlighting the need for multi-disciplinary teams to engineer practical, real-world solutions. Overall, DL shows immense potential to improve the efficiency and accuracy of trauma imaging, but thoughtful development and validation are critical to ensure these technologies positively impact patient care.</div></div>","PeriodicalId":8934,"journal":{"name":"Biomedical Journal","volume":"48 1","pages":"Article 100743"},"PeriodicalIF":4.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11751421/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140850676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both adipose tissue and circadian rhythms play critical roles in maintaining energy homeostasis, and their dysfunction is closely linked to obesity. This study aimed to assess the effects of chronic low-dose SR9009, a REV-ERB ligand, on circadian disruption induced by constant light exposure in mice.Material and methods: Mice were exposed to constant light for eight weeks (LL mice), resulting in increased body weight, insulin resistance, white fat mass, and altered circadian clock gene expression. Low-dose SR9009 (10 mg/kg daily) was administered chronically to assess its impact on these metabolic disruptions.Results: LL mice treated with SR9009 for eight weeks showed reduced weight gain, insulin resistance, and white fat mass but no significant impact on overall energy homeostasis. SR9009 suppressed Bmal1 expression and restored Rev-erbα and Rev-erbβ expression in white and brown adipose tissue (WAT and BAT). In vitro studies using 3T3-L1 cells indicated that SR9009 inhibited adipogenesis, leading to further investigation in vivo. SR9009 restored ChREBP1a and Srebp-1c expression in BAT but did not affect inflammatory cytokine or adipokine gene expression, nor did it restore Fasn, Pparγ, and Prom1 expression in both WAT and BAT.Conclusions: These findings suggest that SR9009 may be a potential therapeutic for preventing weight gain and insulin resistance caused by circadian disruptions, likely through adipogenesis inhibition, though its effects on other metabolic pathways remain limited at low doses.","PeriodicalId":8934,"journal":{"name":"Biomedical Journal","volume":" ","pages":"100830"},"PeriodicalIF":4.1,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142969464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The histone deacetylases (HDACs) are known to significantly regulate in regulating neuropathic pain, but their involvement in nociceptive hypersensitivity during sleep deprivation is still not fully understood. Utilizing a modified multi-platform water environment technique to establish a sleep deprivation model. We measured the expression levels of HDAC1/2 in the medial prefrontal cortex (mPFC) through immunoblotting and real-time quantitative PCR. The presence of pyroptosis was determined using a TUNEL assay. Suberoylanilide hydroxamic acid (SAHA), an HDAC inhibitor employed clinically, was injected into the peritoneal cavity to inhibit HDAC2 expression. Animal pain behaviors were evaluated by measuring paw withdrawal thresholds (PWTs) and paw withdrawal latencies (PWLs). Our findings indicate that sleep deprivation leads to increased nociceptive hypersensitivity, an upregulation of HDAC2 expression in the mPFC, a downregulation of the expression of nuclear factor erythroid 2-related factor 2 (NRF2), and changes in markers of oxidative stress in rats. SAHA, the HDAC inhibitor, enhanced NRF2 expression by inhibiting HDAC2, which consequently ameliorated oxidative stress and mitigated nociceptive hypersensitivity in rats. The incidence of apoptosis was found to be higher in the mPFC tissues of sleep deprivation rats, and the intraperitoneal administration of SAHA decreased this apoptosis. The co-injection of SAHA and the NRF2 inhibitor ML385 into sleep deprivation rats negated the beneficial effects of SAHA. In conclusion, HDAC2 is implicated in the induction of oxidative stress and apoptosis by suppressing NRF2 levels, thereby exacerbating nociceptive hypersensitivity in sleep deprivation rats.","PeriodicalId":8934,"journal":{"name":"Biomedical Journal","volume":" ","pages":"100826"},"PeriodicalIF":4.1,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142926389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seasonal solar variations, the sunspot cycle and anthropogenic electromagnetic fields can also influence biological rhythms. The possible mechanisms underlying these effects are discussed, which include resonance, radical-pair formation in retina cryptochromes, ion cyclotron resonance, and interference, ultimately leading to variations in melatonin and cortisol. Intracellular water, which represents a coherent, ordered phase that is sensitive to infrared light and electromagnetic fields, may also respond to solar variations and man-made electromagnetic fields.

The review adheres to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, which provide criteria for reporting systematic reviews and meta-analyses. It also utilizes the PICOS (Population, Intervention, Comparison, Outcome, Study design) framework to formulate research questions and structure literature searches. A thorough search of multiple databases yielded 1,434 relevant articles, supplemented by an additional 55 articles obtained through manual searches. The review includes a detailed analysis of the XR workflow, its surgical applications, and associated outcomes. It emphasizes the practical benefits of XR in preoperative planning, intraoperative navigation, and postoperative assessment. Furthermore, the paper discusses the challenges, opportunities, and future prospects of XR in pediatric neurosurgery, including its effects on surgical outcomes, medical education, and patient care. By synthesizing technological developments with clinical applications, this review provides a comprehensive understanding of the multifaceted roles of AR and VR in pediatric neurosurgical practice. It covers innovative methods, applicable scenarios, datasets, and metrics, along with a comparative analysis of state-of-the-art techniques, considering differences in input data.
