Myocardial infarction causes scarring and loss of functional capacity of the heart, because the heart is itself unable to repair the damaged area. While the development of new forms of treatment for the repair of myocardial destruction has actually been investigated by introducing into the heart various stem cells present in an adult human, the efficacy of the treatments conducted in the studies has so far unfortunately been low. Embryonic stem cells and iPS cells are a highly significant research subject. Cardiomyocytes differentiated from stem cells are being studied also in drug testing, and they are expected to revolutionize drug development and safety tests of novel drugs as well as enable personalized medication in the future.

Risk analysis of cardiovascular toxicity in patients with lymphoma treated with CD19 CAR T cells.
J Transl Med

Department of Hematology Oncology, Affiliated Hospital of Guizhou Medical University, No. 4 Bei Jing Road, Yunyan District, Guiyang, 550004, Guizhou, China.
Background: Anti-CD19 chimeric antigen receptor (CAR) T cell therapy is a common, yet highly efficient, cellular immunotherapy for lymphoma. However, many recent studies have reported on its cardiovascular (CV) toxicity. This study analyzes the cardiotoxicity of CD19 CAR T cell therapy in the treatment of lymphoma for providing a more valuable reference for clinicians.

Background: Glioblastoma multiforme (GBM) exhibits a cellular hierarchy with a subpopulation of stem-like cells known as glioblastoma stem cells (GSCs) that drive tumor growth and contribute to treatment resistance. NAD(H) emerges as a crucial factor influencing GSC maintenance through its involvement in diverse biological processes, including mitochondrial fitness and DNA damage repair. However, how GSCs leverage metabolic adaptation to obtain survival advantage remains elusive.

Background: X chromosome inactivation (XCI) is a female-specific process in which one X chromosome is silenced to balance X-linked gene expression between the sexes. XCI is initiated in early development by upregulation of the lncRNA Xist on the future inactive X (Xi). A subset of X-linked genes escape silencing and thus have higher expression in females, suggesting female-specific functions.

Hematopoietic stem cell transplantation (HSCT) is a highly effective therapy for malignant blood illnesses that pose a high risk, as well as diseases that are at risk due to other variables, such as genetics. However, the prevalence of graft-versus-host disease (GVHD) has impeded its widespread use. Ensuring the stability of microbial varieties and associated metabolites is crucial for supporting metabolic processes, preventing pathogen intrusion, and modulating the immune system.

Sci Rep
January 2025
Stem Cells Technology Research Center, Shiraz University of Medical Sciences, Shiraz, Iran.
In this study, new cinnamic acid linked to triazole acetamide derivatives was synthesized and evaluated for anti-Alzheimer and anti-melanogenesis activities. The structural elucidation of all analogs was performed using different analytical techniques, including H-NMR, C-NMR, mass spectrometry, and IR spectroscopy. The synthesized compounds were assessed in vitro for their inhibitory activities against acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and tyrosinase enzymes.
