The article discusses the informative significance and pertinence of cytogenetic analysis of peripheral blood lymphocytes to the clinical-physiological investigations of cosmonauts conducted before and after space missions (SM) of varying duration. The authors point out high sensitivity of the technique, relative simplicity and affordability of the analysis of instable chromosomal aberrations including such radiation effect markers as dicentrics and centric rings. Cytogenetic investigation of cosmonauts could be used to estimate ionizing radiation dose, and to predict delayed effects.

Complete blood counts as potential risk factors of early dissemination to liver and lungs in resected colorectal cancer: a retrospective cohort study.

Purpose: Liver and lung metastases demonstrate distinct biological, particularly immunological, characteristics. We investigated whether preoperative complete blood count (CBC) parameters, which may reflect the immune system condition, predict early dissemination to the liver and lungs in colorectal cancer (CRC).
Methods: In this retrospective single-centre study, we included 268 resected CRC cases with complete 2-year follow-up and analysed preoperative CBC for association with early liver or lung metastasis development.

This study aimed to develop and validate a nomogram based on lymphocyte subtyping and clinical factors for the early and rapid prediction of Intra-abdominal candidiasis (IAC) in septic patients. A prospective cohort study of 633 consecutive patients diagnosed with sepsis and intra-abdominal infection (IAI) was performed. We assessed the clinical characteristics and lymphocyte subsets at the onset of IAI.

Background: Synthetic cannabinoids are one of the most identified abused drugs nowadays. Their popularity is due to their psychoactive effects, which resemble delta 9 tetrahydrocannabinol. This study investigates the genotoxic potential of three synthetic cannabinoids of indazole-passed drugs, AB-Fubinaca, AMBFubinaca, and EMB-Fubinaca (at a final concentration of 200 nM).

Natural killer (NK) cells can control metastasis through cytotoxicity and IFN-γ production independently of T cells in experimental metastasis mouse models. The inverse correlation between NK activity and metastasis incidence supports a critical role for NK cells in human metastatic surveillance. However, autologous NK cell therapy has shown limited benefit in treating patients with metastatic solid tumors.

Objective: A pathogenetic role of CD8+ T lymphocytes in radiographic axial spondyloarthritis (r-axSpA) and other spondyloarthritis (SpA) is sustained by genome-wide association studies (GWAS) and by the expansion of public T cell clonotypes in the target tissues. This study investigates the migration of CD8+ T cells, along with their phenotype and functions in patients with r-axSpA and psoriatic arthritis (PsA).
Methods: Peripheral blood CD8+ and CD4+ T cells were isolated from r-axSpA (n= 128), PsA (n= 60) and rheumatoid arthritis (RA, n= 74) patients and healthy donors (HD, n= 79).
