This chapter provides a succinct summary of the nephrotoxic effects of a number of metals/metalloids on an individual or mixture basis. There is a discussion of routes of exposure, mechanisms of uptake by renal cells and the potential impact of nanomaterials on these processes. An emphasis is placed on the toxicity of these metals/ metalloids to individual cell types in the kidney and the application of biomarkers for the early detection of kidney cell injury prior to the onset of an overt clinical state such as end-stage renal disease. The issue of interactions between nephrotoxic metals in mixture exposures is discussed in relation to the application of molecular biomarkers for early detection of renal cell injury.

Background: Vascular calcification is a detrimental aging pathology markedly accelerated in patients with chronic kidney disease. Prelamin A is a biomarker of vascular smooth muscle cell aging that accelerates calcification however the mechanisms remain undefined.
Methods: Vascular smooth muscle cells were transduced with prelamin A using an adenoviral vector and epigenetic modifications were monitored using immunofluorescence and targeted polymerase chain reaction array.

The growing prevalence of the Alzheimer's disease (AD) is an increasing public health concern that led to French recommendations for timely AD diagnosis and patient management as well as a territorial coverage of specialized structures [Memory Centers including Resources and Memory Research Centers (RMRC) and Memory Consultations (MC)]. In view of the potential availability of Disease Modifying Therapies (DMTs), this French observatory aimed to describe the current organization of the Memory Centers, and the care pathway of patients suffering from early AD. Overall, 12 of the 28 RMRC and 44 of the 250 MC solicited by the Federation of Memory Centers participated in this study.

Objective: This study aims to evaluate the association between the white blood cell-to-platelet ratio (WPR) and 28-day all-cause mortality among patients experiencing cardiac arrest.
Methods: Utilizing data from 748 cardiac arrest patients in the Medical Information Mart for Intensive Care-IV (MIMIC-IV) 2.2 database, machine learning algorithms, including the Boruta feature selection method, random forest modeling, and SHAP value analysis, were applied to identify significant prognostic biomarkers.

Background: Emerging evidence underscores the comorbidity mechanisms among autoimmune diseases (AIDs), with innovative technologies such as single-cell RNA sequencing (scRNA-seq) significantly advancing the explorations in this field. This study aimed to investigate the shared genes among three AIDs-Multiple Sclerosis (MS), Systemic Lupus Erythematosus (SLE), and Rheumatoid Arthritis (RA) using bioinformatics databases, and to identify potential biomarkers for early diagnosis.
Methods: We retrieved transcriptomic data of MS, SLE, and RA patients from public databases.
A novel oncolytic Vaccinia virus armed with IL-12 augments antitumor immune responses leading to durable regression in murine models of lung cancer.

Oncolytic vaccinia viruses (VVs) are potent stimulators of the immune system and induce immune-mediated tumor clearance and long-term surveillance against tumor recurrence. As such they are ideal treatment modalities for solid tumors including lung cancer. Here, we investigated the use of VVL-m12, a next-generation, genetically modified, interleukin-12 (IL-12)-armed VV, as a new therapeutic strategy to treat murine models of lung cancer and as a mechanism of increasing lung cancer sensitivity to antibody against programmed cell death protein 1 (α-PD1) therapy.
