In patients with multiple sclerosis the reduction of DNA excision reparation capacity of peripheral blood lymphocytes was found to correlate with the disease severity but not with its duration. These changes and the increase in the DNA reparative synthesis along with the lymphocytes DNA structural changes are considered as the evidence of impaired lymphocytes genome stability in this ailment. Their possible role in the development of immunodeficiency in multiple sclerosis is discussed.

Purpose: Blood lactate concentration is commonly used to assess metabolic demand and skeletal muscle training response. The objective of the pilot study was to investigate if a change in blood lactate was detectable in an anaerobically designed vocal demand task vocal capacity anaerobic task (VCAT) and determine if the developed vocal demand task may assess the anaerobic capacity of the voice musculature, like anaerobic power tests commonly used in applied exercise science.
Methods: A prospective repeated measures study quantified blood lactate concentration preVCAT and postVCAT in vocally healthy adults.

Introduction: The Quality by Design (QbD) approach for developing cell therapy products using mesenchymal stromal/stem cells (MSCs) is a promising method for designing manufacturing processes to improve the quality of MSC products. It is crucial to ensure the reproducibility and robustness of the test system for evaluating critical quality attributes (CQAs) in the QbD approach for manufacturing of pharmaceutical products. In this study, we explored the key factors involved in establishing a robust evaluation system for the immunosuppressive effect of MSCs, which can be an example of a CQA in developing and manufacturing therapeutic MSCs for treating graft-versus-host disease, , and we have identified method attributes to increase the robustness of a simple assay to assess the immunosuppressive effects of MSCs.

Osteopetrosis is a group of genetically and clinically diverse inherited disorders characterized by an increase in bone density. The main known cause is an abnormality in the development or function of osteoclasts. Hence, the process of bone resorption is impaired, resulting in: 1- a reduction in bone marrow volume and, subsequently, a decrement in the hematopoietic capacity of bone marrow, which leads to anemia and compromised immunological function; 2- improper bone development, which leads to pressure on peripheral nerves, causing auditory, visual, and movement impairments; and 3- disturbance in the formation of bone microstructure that leads to susceptibility to bone fracture.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has led to widespread post-acute sequelae of COVID-19 (PASC), affecting multiple body systems. Despite its prevalence, PASC's pathogenesis remains unclear, with hypotheses suggesting viral persistence, immune activation, and autoimmune responses among the pathogenetic mechanism. This study aimed to evaluate T cell memory response in PASC patients, one year post-hospital discharge and correlate it with clinical parameters to identify a potential PASC-associated fingerprint.

Background: Supervised exercise programs improve walking impairment and quality of life (QoL) in patients with peripheral artery disease (PAD). However, such programs are underutilized, due to their limited accessibility. A feasible and effective exercise program is needed.
