It is assumed that hemodialysis treatment can diminish the levels of genetic damage in circulating lymphocytes by cleaning the blood of uremic toxins that cause oxidative stress. However, the hemodialysis process by itself may also induce genomic damage by producing reactive oxygen species (ROS). We conducted a follow-up study in a group of 70 hemodialysis patients followed for a mean time of 15 months. We investigated the effect of exposure time in hemodialysis on the levels of genetic damage in peripheral blood lymphocytes using the micronucleus assay. In addition, genetic damage after in vitro irradiation with 0.5 Gy was also analyzed to evaluate changes in radiosensitivity. Our results showed that, at the end of the study, there was a decrease in both the basal levels of genetic damage (9.9 ± 1.0 vs. 7.6 ± 0.7) and radiosensitivity values (38.5 ± 3.0 vs. 27.6 ± 2.4). We conclude that hemodialysis procedures may act as an ameliorating factor reducing the genetic damage present in chronic kidney disease patients.

A rapidly growing number of chimeric antigen receptors (CARs) is being translated into cell therapy for malignant and autoimmune diseases. While cancer cell-selective CAR targeting is undergoing continuous refinement, specific testing for overlooked recognition of healthy tissues is commonly not performed, which potentially results in underestimating of the risk of severe tissue damage upon CAR T cell application. Using the FcμR/IgM receptor/FAIM3/TOSO-specific CAR, designed to target chronic lymphocytic leukemia cells, we exemplarily outline a screen to uncover reactivities to healthy tissues and discuss the value of such pre-clinical testing to improve safety in CAR T cell application.

Objective: The aim of our study was to characterize the spectrum of mutations in muscle-invasive bladder cancer (MIBC) in the Chinese population, identifying mutational features and exploring potential therapeutic targets.
Methods: We collected samples from 62 Chinese patients with MIBC. For each patient, tumor tissues or blood samples were collected and sequenced by whole exome sequencing.

The São Paulo state citrus belt in Brazil is a major citrus production region. Since at least 1957, citrus plantations in this region have been affected by citrus canker, an economically damaging disease caused by subsp. ().

NKTCL is a highly aggressive malignant tumor, especially prevalent in the southern regions of China. Although chemotherapy regimens based on ADM have achieved certain therapeutic effects in early treatment, the issue of ADM resistance severely limits the therapeutic efficacy and makes it difficult to improve patient survival rates. Our research results indicate that the expression level of APOC1 is closely related to the sensitivity of NKTCL cells to ADM.
