Nanomaterials represent a promising and versatile platform for the delivery of therapeutics to the brain. Treatment of brain tumors has been a long-standing challenge in the field of neuro-oncology. The current standard of care - a multimodal approach of surgery, radiation and chemotherapy - yields only a modest therapeutic benefit for patients with malignant gliomas. A major obstacle for treatment is the failure to achieve sufficient delivery of therapeutics at the tumor site. Recent advances in local drug delivery techniques, along with the development of highly effective brain-penetrating nanocarriers, have significantly improved treatment and imaging of brain tumors in preclinical studies. The major advantage of this combined strategy is the ability to optimize local therapy, by maintaining an effective and sustained concentration of therapeutics in the brain with minimal systemic toxicity. This review highlights some of the latest developments, significant advancements and current challenges in local delivery of nanomaterials for the treatment of brain tumors.

Purpose: To investigate the technique for dorsal median sulcus (DMS) mapping and assess its application value in preserving dorsal columnn (DC) function during intramedullary space occupying surgery based on a single-center experience.
Methods: A retrospective analysis was conducted on 41 cases of intramedullary spinal cord tumor admitted to the Department of Neurosurgery at the First Affiliated Hospital of Xiamen University from March 2017 to August 2023. All included cases underwent intraoperative electrophysiological monitoring, and were divided into a study group (n = 18) and a control group (n = 23), based on whether DMS mapping technique was utilized.

Glioma is a common and destructive brain tumor, which is highly heterogeneous with poor prognosis. Developing diagnostic and prognostic markers to identify and treat glioma early would significantly improve the therapeutic outcomes. Here, we conducted RNA next-generation sequencing with 33 glioma samples and 15 normal brain samples.

Localization of function within the brain and central nervous system is an essential aspect of clinical neuroscience. Classical descriptions of functional neuroanatomy provide a foundation for understanding the functional significance of identifiable anatomic structures. However, individuals exhibit substantial variation, particularly in the presence of disorders that alter tissue structure or impact function.

Triple-negative breast cancer (TNBC) is a clinically aggressive subtype of breast cancer that remains an unmet medical need. Because TNBC cells do not express the most common markers of breast cancers, there is an active search for novel molecular targets in triple-negative tumors. Additionally, this subtype of breast cancer presents strong immunogenic characteristics which have been encouraging the development of immunotherapeutic approaches against the disease.

Glioblastoma (GBM) is described as a group of highly malignant primary brain tumors and stands as one of the most lethal malignancies. The genetic and cellular characteristics of GBM have been a focal point of ongoing research, revealing that it is a group of heterogeneous diseases with variations in RNA expression, DNA methylation, or cellular composition. Despite the wealth of molecular data available, the lack of transferable pre-clinic models has limited the application of this information to disease classification rather than treatment stratification.
