A longitudinally extensive H3 K27M-mutant diffuse midline glioma in an elderly patient clinically mimicking central nervous system inflammation: a case report.

Diffuse midline gliomas, H3 K27M-mutant, World Health Organization (WHO) grade IV represent a distinct glioma entity with a predominantly paediatric presentation and remarkably poor prognosis. This report presents a case of a 73-year-old woman with a diffuse midline glioma, H3 K27M-mutant, WHO grade IV with a remarkable longitudinal extension, extending from the cervical myelon to the basal ganglia. On imaging, the lesion was predominantly suggestive of inflammatory oedema, and it was clinically associated with progressive hemi- and later tetraparesis with severe autonomic and bulbar symptoms.

Connection between small vessel disease related stroke and the MTHFR C677T polymorphism in a Hungarian population.

Introduction: There are conflicting results in the literature regarding the connection between thrombophilias and ischaemic stroke. However, most of the clinical studies have not differentiated between various ischaemic stroke subtypes. Our aim was to investigate whether there is an association between the methylene tetrahydrofolate reductase (MTHFR) C677T polymorphism and ischaemic stroke due to small vessel disease (SVD) in patients ≤50 years of age.

A validated UHPLC-MS method for tryptophan metabolites: Application in the diagnosis of multiple sclerosis.

The simultaneous quantitative estimation of tryptophan (TRP) and its metabolites represents a great challenge because of their diverse chemical properties, e.g., presence of acidic, basic, and nonpolar functional groups and their immensely different concentrations in biological matrices.

Mitochondria, Oxidative Stress and the Kynurenine System, with a Focus on Ageing and Neuroprotection.

In this review, the potential causes of ageing are discussed. We seek to gain insight into the main physiological functions of mitochondria and discuss alterations in their function and the genome, which are supposed to be the central mechanisms in senescence. We conclude by presenting the potential modulating role of the kynurenine pathway in the ageing processes.
