Characterizing oxidative stress induced by Aβ oligomers and the protective role of carnosine in primary mixed glia cultures.

Alzheimer's disease (AD) is a neurodegenerative disorder characterized by cognitive decline and memory loss. A critical aspect of AD pathology is represented by oxidative stress, which significantly contributes to neuronal damage and death. Microglia and astrocytes, the primary glial cells in the brain, are crucial for managing oxidative stress and supporting neuronal function.

Exploring SERPINA3 as a neuroinflammatory modulator in Alzheimer's disease with sex and regional brain variations.

SERPINA3, a serine protease inhibitor, is strongly associated with neuroinflammation, a typical condition of AD. Its expression is linked to microglial and astrocytic markers, suggesting it plays a significant role in modulating neuroinflammatory responses. In this study, we examined the SERPINA3 expression levels, along with CHI3L1, in various brain regions of AD patients and non-demented healthy controls (NDHC).

Parallel single-cell metabolic analysis and extracellular vesicle profiling reveal vulnerabilities with prognostic significance in acute myeloid leukemia.

Acute myeloid leukemia (AML) is an aggressive disease with a high relapse rate. In this study, we map the metabolic profile of CD34(CD38) AML cells and the extracellular vesicle signatures in circulation from AML patients at diagnosis. CD34 AML cells display high antioxidant glutathione levels and enhanced mitochondrial functionality, both associated with poor clinical outcomes.

Engineering of the genetic code.

The genetic code is a universally conserved mechanism that translates genetic information into proteins, consisting of 64 codons formed by four nucleotide bases. With a few exceptions, the genetic code universally encodes 20 canonical amino acids (AAs) and three stop signals, with many AAs represented by multiple codons. Genetic engineering has expanded this system through approaches like codon reassignment and synthetic base pair introduction, allowing for the incorporation of noncanonical AAs (ncAAs) into proteins, known as genetic code expansion (GCE).

Advancements in glycan analysis: high performance anion exchange chromatography-pulsed amprometric detection coupled with mass spectrometry for structural elucidation.

Carbohydrates are essential biomolecules that play a vital role in various biological processes across humans, plants, and bacteria. Despite their ubiquity, the structural elucidation of carbohydrates, particularly oligo- and polysaccharides, remains a significant challenge due to their complex and heterogeneous nature. The high-performance anion exchange chromatography (HPAEC) or called ion chromatography (IC) coupled with pulsed amperometric detection (PAD) has emerged as a powerful tool for highly effective separation and highly specific detection of glycans.

Clinical importance of patient-reported outcome measures in severe asthma: results from U-BIOPRED.

Rationale: Knowledge about the clinical importance of patient-reported outcome measures (PROMs) in severe asthma is limited.

Objectives: To assess whether and to what extent asthma exacerbations affect changes in PROMS over time and asthma-specific PROMs can predict exacerbations in adult patients with severe asthma in usual care.

Methods: Data of 421 patients with severe asthma (62% female; mean age 51.

State of the art of CT myocardial perfusion.

Coronary computed tomography angiography (CCTA) is a powerful tool to rule out coronary artery disease (CAD). In the last decade, myocardial perfusion CT (CTP) technique has been developed for the evaluation of myocardial ischemia, thereby increasing positive predictive value for diagnosis of obstructive CAD. A diagnostic strategy combining CCTA and perfusion acquisitions provides both anatomical coronary evaluation and functional evaluation of the stenosis, increasing the specificity and the positive predictive value of cardiac CT.

International consensus statement on microbiome testing in clinical practice.

There is growing interest in the potential exploitation of the gut microbiome as a diagnostic tool in medicine, but evidence supporting its clinical usefulness is scarce. An increasing number of commercial providers offer direct-to-consumer microbiome diagnostic tests without any consensus on their regulation or any proven value in clinical practice, which could result in considerable waste of individual and health-care resources and potential drawbacks in the clinical management of patients. We convened an international multidisciplinary expert panel to standardise best practices of microbiome testing for clinical implementation, including recommendations on general principles and minimum requirements for their provision, indications, pre-testing protocols, method of analyses, reporting of results, and potential clinical value.

Treatment is often challenging because of limited approved drugs, and severe CHE is associated with reduced quality of life (QoL) and poor overall health measures in terms of psychological, functional, and occupational challenges. This study aims to describe the real-life management practices of Italian dermatologists who frequently treat patients with CHE, compare these practices with existing guidelines, and propose practical clinical recommendations for the management of these patients.

Inhibition of zDHHC7-driven protein S-palmitoylation prevents cognitive deficits in an experimental model of Alzheimer's disease.

Protein post-translational modifications (PTM) play a crucial role in the modulation of synaptic function and their alterations are involved in the onset and progression of neurodegenerative disorders. S-palmitoylation is a PTM catalyzed by zinc finger DHHC domain containing (zDHHC) S-acyltransferases that affects both localization and activity of proteins regulating synaptic plasticity and amyloid-β (Aβ) metabolism. Here, we found significant increases of both zDHHC7 expression and protein S-palmitoylation in hippocampi of both 3×Tg-AD mice and post-mortem Alzheimer's disease (AD) patients.

Fugitive Acromegaly: A Historical, Clinical, and Translational Perspective.

The term 'fugitive acromegaly' was introduced by the neurosurgeons Bailey and Cushing in 1928 to describe subjects manifesting signs and symptoms of somatotroph hyperfunction with pituitary insufficiency. Currently, it identifies patients with subtle acromegalic dysmorphisms and inconsistent hormonal profile, possibly presenting only with hyperprolactinemia and related clinical symptoms. Patients have rapidly growing, locally invasive, relapsing pituitary macrotumors that can be classified as either acidophil stem cell tumors (ASCTs) or sparsely granulated somatotroph tumors (SGSTs), both of PIT1-lineage.
