Karyotypes of 9 malignant melanoma patients has been described. It is ascertained that most often the damage is observed in chromosomes 1, 6, 7, 9 and 17, which is consistent with the data in the literature. Besides chromosomes 5 and 13 are also often involved in different rearrangements. Recurring aberrations are not discovered. Any correlation between survival and non-recurrent chromosomal aberrations is not discovered.

Background: We explored the relationship of neuropsychiatric symptoms (assesses by NPI) and Alzheimer disease pathophysiology from blood AB42/40, GFAB, NFL, and pTau181. We also investigated if age and cognition were related to these neuropsychiatric symptoms.
Method: 222 subjects included 96 dementia, 66 MCI, and 60 normal controls (NC).
Potentially actionable molecular alterations in particular related to poor oncologic outcomes in salivary gland carcinomas.

Aim: The study was designed to evaluate molecular alterations, relevant to the prognosis and personalized therapy of salivary gland cancers (SGCs).
Materials And Methods: DNA was extracted from archival tissue of 40 patients with various SGCs subtypes. A targeted next-generation sequencing (NGS) panel was used for the identification of small-scale mutations, focal and chromosomal arm-level copy number changes.

Lung endothelial cells (ECs) are essential for maintaining organ function and homeostasis. Despite sharing some common features with ECs from organ systems, lung ECs exhibit significant heterogeneity in morphology, function, and gene expression. This heterogeneity is increasingly recognized as a key contributor to the development of pulmonary diseases like pulmonary hypertension (PH).

C1QBP exhibits heightened expression across a spectrum of tumours, thereby fostering their proliferation and metastasis, rendering it a pivotal therapeutic target. Nevertheless, to date, no pharmacological agents capable of directly targeting and inducing the degradation of C1QBP have been identified. In this study, we have unveiled a new peptide, PDBAG1, derived from the precursor protein GPD1, employing a peptidomics-based drug screening strategy.
