Ischemic stroke (IS) is a pathological condition characterized by the cessation of blood flow due to factors such as thrombosis, inflicting severe damage to the cranial nervous system and resulting in numerous disabilities including memory impairments and hemiplegia. Despite the critical nature of this condition, therapeutic options remain limited, with a pressing challenge being the development of treatments aimed at restoring neurological function. In this study, we leveraged zebrafish, renowned for their exceptional regenerative capabilities, to analyze the pathology of IS and the subsequent recovery process.

Alzheimer's disease (AD), an age-related neurodegenerative disease, brings huge damage to the society, to the whole family and even to the patient himself. However, until now, the etiological factor of AD is still unknown and there is no effective treatment for it. Massive deposition of amyloid-beta peptide(Aβ) and hyperphosphorylation of Tau proteins are acknowledged pathological features of AD.

Background: Mutations in STK11, KEAP1, and SMARCA4 predispose to inferior immune checkpoint inhibitor (ICI) efficacy in non-small cell lung cancer (NSCLC), particularly among KRAS-mutant cases. However, the frequency, clinicopathologic features, and clinical impact of deletions in these genes are poorly characterized.

Methods: Clinicopathologic correlates of STK11, KEAP1, and SMARCA4 deletion were analyzed in nonsquamous NSCLCs at Dana-Farber Cancer Institute (DFCI).

Introduction: Amivantamab, an EGFR-MET bispecific antibody, is approved for multiple indications in EGFR-mutated advanced non-small cell lung cancer (NSCLC) as monotherapy or combined with other agents. Intravenous amivantamab is associated with a 67% infusion-related reactions (IRR) rate.

Methods: The phase 2 SKIPPirr study (NCT05663866) enrolled patients with EGFR-mutated (Ex19del/L858R) advanced NSCLC after progression on osimertinib and platinum-based chemotherapy who received intravenous amivantamab plus oral lazertinib (amivantamab-lazertinib), a third-generation tyrosine kinase inhibitor.

Background: In the context of the ongoing war in the Gaza Strip, the Gaza Health Ministry (GHM) has reported 45 936 fatalities and more than 10 000 individuals missing or under the rubble for the period Oct 7, 2023, to Jan 8, 2025. The scope of this death count is difficult to fully interpret because it does not account for the size and age distribution of the Gaza Strip population. Moreover, the quality of this death count has been questioned.

Trans-active response DNA-binding protein-43 (TDP-43) is the major pathological protein in motor neuron disease and TDP-43 pathology has been described in the brains of up to 50% of patients with Alzheimer disease (AD). Hippocampal sclerosis of aging (HS-A), an age-related neuropathology characterized by severe neuronal loss and gliosis in CA1 and/or subiculum, is found in ∼80% of cases that are positive for phosphorylated TDP-43. HS-A is seen as a co-pathology in cases with AD, limbic-predominant age-related TDP-43 encephalopathy neuropathologic changes (LATE-NC), and frontotemporal degeneration.

Electronic address:

The extracellular matrix (ECM) plays an important role in the central nervous system (CNS), shaping tissue structure and functions as well as contributing to the pathology of chronic diseases such as multiple sclerosis (MS). ECM components, including fibulin-2 (FBLN2) and chondroitin sulfate proteoglycans (CSPGs), may impact neuroinflammation and remyelination. We investigated the capacity of FBLN2 to modulate immune responses and evaluated its interaction with CSPGs in experimental autoimmune encephalomyelitis (EAE), a common model for MS.

Cardiotoxic effect of Doxorubicin (Dox) limits its clinical application. Previously, we reported that Dox induces phosphorylation of lamin A/C (pS22 lamin A/C), increased nuclear size, damage to the nuclear membrane, and cell death. However, the activation of signalling pathway during this event remains elusive, and it is unclear whether increased phospho-lamin A/C activates the cell death pathway in heart.

Mammalian hibernation offers a unique model for exploring neuroprotective mechanisms relevant to neurodegenerative diseases. In this study, we employed untargeted lipidomics with iterative tandem mass spectrometry (MS/MS) to profile the brain lipidome of Syrian hamsters across different hibernation stages: late torpor, arousal, and euthermia (control). Previously, a lipid species identified as methyl-PA(16:0/0:0) showed a significant increase during torpor, but its precise structure was unresolved due to technological constraints.

Environmental exposure to single and combined ZnO and TiO nanoparticles: Implications for rainbow trout gill immune functions and microbiota.

Research Unit in Environmental and Evolutionary Biology (URBE), Institute of Life Earth and Environment, University of Namur, 61 Rue de Bruxelles, B-5000, Namur, Belgium.

ZnO and TiO nanoparticles (NPs) are widely employed for their antibacterial properties, but their potential environmental impact is raising concerns. This study aimed to assess their single and combined effects at environmentally relevant concentrations (210 μg L) on rainbow trout (Oncorhynchus mykiss) gills microbiota and immune functions. 16S rRNA gene sequencing performed after 5 and 28 days of exposure suggests that TiO NPs had a more immediate impact on bacterial diversity, while prolonged exposure to the mixture altered community composition.

Background: The application of natural language processing in medicine has increased significantly, including tasks such as information extraction and classification. Natural language processing plays a crucial role in structuring free-form radiology reports, facilitating the interpretation of textual content, and enhancing data utility through clustering techniques. Clustering allows for the identification of similar lesions and disease patterns across a broad dataset, making it useful for aggregating information and discovering new insights in medical imaging.

This study aims to investigate the expression of seven cancer testis antigens (MAGE-A1, MAGE-A4, MAGE-A10, MAGE-A11, PRAME, NY-ESO-1 and KK-LC-1) in pan squamous cell carcinoma and their prognostic value, thus assessing the potential of these CTAs as immunotherapeutic targets. The protein expression of these CTAs was evaluated by immunohistochemistry in 60 lung squamous cell carcinoma (LUSC), 62 esophageal squamous cell carcinoma (ESCA) and 62 head and neck squamous cell carcinoma (HNSC). The relationship between CTAs expression and progression-free survival (PFS) was assessed.

Adaptive immune resistance in cancer describes the various mechanisms by which tumors adapt to evade anti-tumor immune responses. IFN-γ induction of programmed death-ligand 1 (PD-L1) was the first defined and validated adaptive immune resistance mechanism. The endoplasmic reticulum (ER) is central to adaptive immune resistance as immune modulatory secreted and integral membrane proteins are dependent on ER.
