Article Abstract
Animal experimentation models are a necessary prerequisite to human trials for the use of regenerative medicine in the treatment of spinal cord injuries. Considerable effort is required for the generation of a consistent and reproducible methodology to incur an injury and evaluate the results. The traumatic contusion model has been accepted as a model that closely mimics a typical human traumatic injury, and here we detail step by step an approach to generate a reproducible lesion in rats. Acute cell transplantation by intramedullar or intrathecal administration is described for regenerative interventions. The same model is suitable to design subacute or chronic therapeutic approaches by interventions 1 week or 1 month after lesion.
renal transplant carcinoma, especially in the context of bilateral renal carcinoma, is rare and often presents as small, low-grade papillary renal cell carcinoma (RCC). There is currently no consensus or effective treatment for advanced metastatic RCC after kidney transplantation. A 40-year-old man developed renal transplant carcinoma with venous thrombus and lung metastases 13 years after transplantation.
Allogeneic hematopoietic stem-cell transplantation (HCT) is one of the principal curative approaches in the treatment of acute myeloid leukemia (AML); however, relapse post-transplantation remains a catastrophic event with poor prognosis. The incidence of relapse has remained unchanged over the last three decades despite an evolving understanding of the immunobiology of the graft-versus leukemia effect and the immune escape mechanisms that lead to post-HCT relapse. The approach to post-transplant relapse is highly individualized and is dictated both by disease biology and genomics as well as the patient's clinical status at the time of relapse and the interval between relapse and transplantation.
African American (AA) women are disproportionally affected by obesity and hyperlipidemia, particularly in the setting of adverse social determinants of health (aSDoH) contributing to health disparities. Obesity, hyperlipidemia, and aSDoH appear to impair Natural Killer cells (NKs). As potential common underlying mechanisms are largely unknown, we sought to investigate common signaling pathways involved in NK dysfunction related to obesity and hyperlipidemia in AA women from under-resourced neighborhoods.
Patients who develop acute myeloid leukemia (AML) after having received treatment for myelodysplastic syndrome (MDS) or related conditions have particularly poor outcomes. This study analyzed adult patients with newly diagnosed AML who previously had MDS, chronic myelomonocytic leukemia (CMML), or MDS/myeloproliferative neoplasm (MPN) overlap syndrome, and who had received hypomethylating agents, chemotherapy, and/or allogeneic stem cell transplantation (HSCT) for these antecedent disorders. From January 2012 to August 2023, we included 673 patients with a median age of 70 years (range, 19-94); 536 (80%) had transformed from MDS, and the remainder from CMML or MDS-MPN.
Background: Hepatocellular carcinoma (HCC) remains a significant global health challenge with limited treatment options. Lenvatinib, a tyrosine kinase inhibitor, has shown promise but is often undermined by the development of drug resistance.
Methods: Utilizing high-throughput sequencing, we investigated the molecular mechanisms underlying lenvatinib resistance in HCC cells, with a focus on metabolic pathways.
