Relationship of Interleukin 6 with Hepatic Steatosis and Liver Fibrosis in Rheumatoid Arthritis at a Rheumatology Care Center in Cartagena, Colombia.

Background/objectives: This study aimed to investigate the association of IL-6 with steatotic liver disease (SLD) and liver fibrosis (LF) in rheumatoid arthritis (RA) patients at a rheumatology center in Cartagena de Indias, Colombia.

Methods: This was a cross-sectional study that included RA and non-RA cases. The level of cellular expression of interleukin 6 (IL-6) was evaluated by flow cytometry in peripheral blood leukocytes, and the presence of SLD and LF was detected by elastosonography.

Effects of Saccharomyces cerevisiae on Pancreatic Alpha and Beta Cells and Metabolic Profile in Broilers.

To evaluate the impact of Saccharomyces cerevisiae (SC) supplementation on pancreatic islet areas, alpha and beta cell populations, blood glucose levels, and lipid profiles in broilers, broilers were randomly assigned to two groups: a control group (T1) without SC and a treatment group (T2) supplemented with SC. Islet areas, alpha and beta cell counts, serum glucose and insulin levels, and lipid profiles were assessed. SC supplementation significantly decreased blood glucose levels compared to the control group.

The pericardium forms as a distinct structure during heart formation.

The heart integrates diverse cell lineages into a functional unit, including the pericardium, a mesothelial sac that supports heart movement, homeostasis, and immune responses. However, despite its critical roles, the developmental origins of the pericardium remain uncertain due to disparate models. Here, using live imaging, lineage tracking, and single-cell transcriptomics in zebrafish, we find the pericardium forms within the lateral plate mesoderm from dedicated anterior mesothelial progenitors and distinct from the classic heart field.

A STAT3 Degrader Demonstrates Pre-clinical Efficacy in Venetoclax resistant Acute Myeloid Leukemia.

Unlabelled: Acute myeloid leukemia (AML) is an aggressive hematologic malignancy that continues to have poor prognosis despite recent therapeutic advances. Venetoclax (Ven), a BCL2-inhibitor has shown a high response rate in AML; however, relapse is invariable due to mitochondrial dysregulation that includes upregulation of the antiapoptotic protein MCL1, a central mechanism of Ven resistance (Ven-res). We have previously demonstrated that the transcription factor STAT3 is upregulated in AML hematopoietic stem and progenitor cells (HSPCs) and can be effectively targeted to induce apoptosis of these aberrant cells.
