Background: Chiasmatic cavernous hemangioma (CCH) is a rare disease. Most cases are treated with surgical resection through approaches such as pterional and orbitozygomatic craniotomy. However, with advancements in surgical technique and heightened patient demand for improved postoperative quality of life, there have been reports in recent years exploring more minimally invasive surgical approaches, such as the subfrontal trans-eyebrow keyhole and endoscopic endonasal transsphenoidal approach.

The escalating volume of decoration and renovation waste (D&RW) amid the rapid urbanization in China has posed significant challenges for the effective recycling of this waste stream, primarily due to the difficulty of accurately assessing its precise composition. To enhance the recycling of high-value materials from D&RW, a comprehensive understanding of its composition and quality is crucial before sorting. In this study, we propose a hybrid method that combines instance segmentation deep learning (DL) models with morphological machine learning (ML) models to automate the classification and evaluation of D&RW.

T helper cells, particularly T follicular helper (T) cells, are essential for the neutralizing antibody production elicited by pathogens or vaccines. However, in immunocompromised individuals, the inefficient support from T cells could lead to limited protection after vaccine inoculation. Here we showed that the conjugation of inducible T cell costimulatory (ICOS) onto the nanoparticle, together with immunogen, significantly enhanced the immune response of the vaccines specific for SARS-CoV-2 or human immunodeficiency virus type-1 (HIV-1) in T-deficient mice.

Article Synopsis
  • Tissue-resident memory T (TRM) cells in bone marrow may impact tumor growth and immune treatment responses in acute myeloid leukemia (AML) patients.
  • A study analyzed bone marrow samples from 49 newly diagnosed AML patients, revealing that CD8 effector memory T cells (similar to TRM) were more prevalent in these patients compared to healthy individuals, and a high percentage correlated with poor survival rates.
  • The research highlighted that while these CD8 TRM-like cells showed signs of exhaustion, they also had characteristics indicating strong growth potential; thus, their accumulation could predict survival outcomes in AML patients.

The development of a vaccine specific to severe acute respiratory syndrome coronavirus 2 Omicron has been hampered due to its low immunogenicity. Here, using reverse mutagenesis, we found that a phenylalanine-to-serine mutation at position 375 (F375S) in the spike protein of Omicron to revert it to the sequence found in Delta and other ancestral strains significantly enhanced the immunogenicity of Omicron vaccines. Sequence FAPFFAF at position 371-377 in Omicron spike had a potent inhibitory effect on macrophage uptake of receptor-binding domain (RBD) nanoparticles or spike-pseudovirus particles containing this sequence.

Polarization imaging technique (PIT) based on a backward scattering 3 × 3 Mueller matrix polarization imaging experimental setup is able to study the optical information and microstructure of glioma and non-glioblastoma tissues from clinical treatment. However, the image contrast of Mueller Matrix Elements (MME) is far from sufficient to provide supplemental information in the clinic, especially in off-diagonal MME. The aim of this work is to propose an innovative method to improve the contrast and quality of PIT images of glioma and non-glioma tissues.

Necroptosis is a recently discovered form of cell death that plays a vital role in the progression of cancer, the spread of metastases, and the immunologic response to tumors. Due to the dual role of necrotic apoptotic processes in tumor pathogenesis and the heterogeneity of gliomas, the function of necroptosis in the glioma microenvironment is still poorly understood. We characterized the expression of necroptosis-related genes (NRGs) within glioma samples at both the genetic and transcriptional levels, identifying three distinct subtypes.

Traumatic brain injury (TBI) is a major global burden of health. As an accepted inflammatory mediator, high mobility group box 1 (HMGB1) is found to be effective in facilitating neurogenesis and axonal regeneration. SH3RF2 (also known as POSHER), an E3 ligase SH3 domain-containing ring finger 2, belongs to the SH3RF family of proteins.

Objectives: To develop and validate a deep learning model for predicting overall survival from whole-brain MRI without tumor segmentation in patients with diffuse gliomas.

Methods: In this multicenter retrospective study, two deep learning models were built for survival prediction from MRI, including a DeepRisk model built from whole-brain MRI, and an original ResNet model built from expert-segmented tumor images. Both models were developed using a training dataset (n = 935) and an internal tuning dataset (n = 156) and tested on two external test datasets (n = 194 and 150) and a TCIA dataset (n = 121).

  • T cell dysregulation plays a significant role in leukemia, particularly in acute myeloid leukemia (AML), where abnormal immune checkpoint proteins may drive disease relapse and progression.
  • The study investigated the expression of TOX, a transcription factor linked to immune regulation, and its co-expression with immune checkpoint proteins PD-1, Tim-3, and CD244 in various T cell subsets from patients with de novo AML compared to healthy individuals.
  • Findings revealed higher levels of TOX+ T cells and increased co-expression with PD-1 and Tim-3 in AML patients, indicating that TOX may be a promising therapeutic target for improving T cell function in AML treatment.

Article Synopsis
  • Diffuse midline glioma (DMG) is a type of aggressive brain tumor (GBM) without effective treatments, but a new therapy called tumor treating fields (TTFields) shows promise in extending patient survival.
  • The case study describes an adult patient diagnosed with thalamus GBM after a car accident, who showed some improvement with standard treatment combined with TTFields, yet experienced growth in other tumor areas (metastases).
  • The findings suggest that while TTFields can enhance survival for DMG patients, it may be insufficient for metastases in lower brain areas, highlighting the need for further research in this aspect.

Thymocyte selection-associated HMG box (TOX) is a transcription factor that belongs to the high mobility group box (HMG-box) superfamily, which includes four subfamily members: TOX, TOX2, TOX3, and TOX4. TOX is related to the formation of multiple malignancies and contributes to CD8+ T cell exhaustion in solid tumors. However, little is known about the role of TOX genes in hematological malignancies.

TOX (thymocyte selection-associated HMG BOX) is a member of a family of transcriptional factors that contain the highly conserved high mobility group box (HMG-box) region. Increasing studies have shown that TOX is involved in maintaining tumors and promoting T cell exhaustion. In this review, we summarized the biological functions of TOX and its contribution as related to lymphocytic malignancies.

Aim: To characterize immune suppression in lymphoma, thymocyte selection-associated high mobility group box protein (TOX) expression and co-expression with programmed cell death receptor-1 (PD-1), T cell immunoglobulin mucin-domain-containing-3 (Tim-3), and CD244 in CD3+, CD4+, CD8+, and regulatory T (Treg) cells from patients with lymphomas were analyzed.

Methods: TOX expression and co-expression with PD-1, Tim-3, and CD244 in CD3+, CD4+, Treg, and CD8+ T cells were analyzed by multi-color fluorescent flow cytometry using peripheral blood (PB) from 13 newly diagnosed, untreated lymphoma patients, and 11 healthy individuals.

Results: An increased percentage of TOX+ CD3+, CD4+, and CD8+ T cells was found in PB from patients with B cell non-Hodgkin's lymphoma (B-NHL) in comparison with healthy controls.

Article Synopsis
  • Immunotherapy using immune checkpoint inhibitors (ICIs) has improved survival rates for solid tumors, but this approach is not yet effective for acute myeloid leukemia (AML) due to limited understanding of immune checkpoint expression in AML.
  • A study analyzed RNA sequencing and mutation data from 176 AML patients and validated findings with bone marrow samples from 62 patients, revealing that high levels of PD-1, PD-L1, and PD-L2 are linked to poorer overall survival.
  • The research also found that specific combinations of these immune checkpoints (like PD-1/CTLA-4 and PD-L2/CTLA-4) are associated with even worse survival rates, suggesting these patterns could help in developing new therapies for AML
