Antioxidant Capacity Is Decreased in Wilson's Disease and Correlates to Liver Function.

The metabolic disorder Wilson's disease (WD) is caused by copper accumulation in the tissues due to a biallelic pathogenic mutation of the gene ATP7B, encoding intracellular copper transporter ATPase-7B. As copper is a redox active metal; aberrations in its homeostasis may create favourable conditions for superoxide-yielding redox cycling and oxidative damage to the cells. We tried to characterise antioxidant defence in WD patients and to evaluate whether it is related to liver function.

Relationship of Corpus Callosum Integrity with Working Memory, Planning, and Speed of Processing in Patients with First-Episode and Chronic Schizophrenia.

There is a paucity of reports examining the relationship between the integrity of the corpus callosum (CC) and different aspects of cognitive functioning in patients with first-episode (FES) and chronic schizophrenia (CS) simultaneously; furthermore, what results exist are inconclusive. We used diffusion tensor imaging tractography to investigate differences in integrity in five regions of the CC between FES, CS, and healthy controls (HC). Additionally, we analyzed correlations between these regions' integrity and working memory, planning, and speed of processing.

Effect of homeostatic iron regulator protein gene mutation on Wilson's disease clinical manifestation: original data and literature review.

Objective: Wilson's disease (WD) is a hereditary disorder of copper metabolism. The metabolic pathways of copper and iron are interrelated. Our goal was to determine the frequency of the two most common mutations in the coding region of the human iron homeostatic protein gene () in Europe: C282Y (rs1800562) and H63D (rs1799945) in WD patients, as well as to analyze their relation with WD phenotypic traits.

Pembrolizumab and atezolizumab in triple-negative breast cancer.

Triple-negative breast cancer (TNBC) is defined by a lack of expression of both estrogen (ER) and progesterone (PgR) receptors as well as human epidermal growth factor receptor 2 (HER2) and is associated with poor prognosis. Moreover, the systemic treatment options are limited. However, the TNBC is more likely than other breast cancer subtypes to benefit from immune checkpoint blockade therapy due to its higher immunogenicity, higher enrichment by tumour-infiltrating lymphocytes (TILs), and higher levels of programmed cell death ligand 1 (PD-L1) expression.

Difference in iron metabolism may partly explain sex-related variability in the manifestation of Wilson's disease.

Background/aim: Wilson's disease (WD) is a hereditary disorder characterized by abnormal metabolism of copper. For unknown reasons, the clinical picture of this disease appears to be sex-dependent. Because the metabolism of copper and iron is interrelated, we aimed to evaluate whether the variability in the clinical picture of WD could be explained by the sex difference in iron metabolism.
