Purpose: Erythropoietin (EPO) is the principal factor regulating red blood cell production in humans. It has been shown that EPO gradually decreases with the progression of diabetic nephropathy and may be used as a marker of severity of disease. In vitro studies have shown that interleukin-10 (IL-10) acts synergistically with EPO to increase stimulation of erythroid differentiation and proliferation. We evaluate serum levels of EPO and IL-10 in children with reflux nephropathy (RN).
Materials And Methods: Serum level of EPO and IL-10 were measured in 32 girls and 22 boys with RN, and in 22 boys and 10 girls who served as healthy controls. Renal scarring was evaluated with Technetium dimercapto-succinic acid scan. RN was severe (less than 20% uptake) in 16 children, moderate (20% to 40% uptake) in 25 and mild RN (greater than 40% uptake) in 13. Because anemia may further stimulate EPO production we also compared the index Hb (hemoglobin) x EPO in all patients. IL-10 and EPO were measured with standard enzyme-linked immunosorbent assay technique. The unpaired t test was used for statistical analysis.
Results: There were no statistically significant differences in the serum levels of EPO in children with RN (6.11 +/- 0.51 mIU/ml) compared to controls (6.42 +/- 0.46 mIU/ml) (p >0.5). Similarly the index Hb x EPO was 75.25 +/- 5.65 in children with RN compared to 73.76 +/- 5.48 in controls. Mean EPO levels were similar for mild, moderate and severe RN. There was no difference in the serum levels of IL-10 in children with RN (23.14 +/- 2.32 pg/ml) compared to controls (22.67 +/- 4.13 pg/ml) (p >0.5).
Conclusions: Although EPO has been reported to be a marker of progressive renal disease in diabetic nephropathy, our data indicate that serum levels of EPO do not reflect the severity of renal parenchymal damage in children with RN.

Aim: To develop pH (pHe)-triggered membrane adhesive nanoliposome (pHTANL) of CD40a to enhance anti-tumor activity in pancreatic cancer while reducing systemic toxicity.
Materials And Methods: A small library of nanoliposomes (NL) with various lipid compositions were synthesized to prepare pH (pHe)-triggered membrane adhesive nanoliposome (pHTANL). Physical and functional characterization of pHTANL-CD40a was performed via dynamic light scattering (DLS), Transmission Electron Microscopy (TEM), confocal microscopy, and flow cytometry.

Background: Ischemic stroke is a prevalent and life-threatening cerebrovascular disease that is challenging to treat and associated with a poor prognosis. Astragaloside IV (AS-IV), a primary bioactive component of Astragali radix, has demonstrated neuroprotective benefits in previous studies. This study aimed to explore the mechanisms through which AS-IV may treat cerebral ischemia-reperfusion injury (CIRI).

The study by Cao aimed to identify early second-trimester biomarkers that could predict gestational diabetes mellitus (GDM) development using advanced proteomic techniques, such as Isobaric tags for relative and absolute quantitation isobaric tags for relative and absolute quantitation and liquid chromatography-mass spectrometry liquid chromatography-mass spectrometry. Their analysis revealed 47 differentially expressed proteins in the GDM group, with retinol-binding protein 4 and angiopoietin-like 8 showing significantly elevated serum levels compared to controls. Although these findings are promising, the study is limited by its small sample size ( = 4 per group) and lacks essential details on the reproducibility and reliability of the protein quantification methods used.

In end-stage kidney disease requiring hemodialysis, patients at nutritional risk have a poor prognosis. The gut microbiota is important for maintaining the nutritional status of patients. However, it remains unclear whether an altered gut microbiota correlates with increased nutritional risk in patients undergoing hemodialysis.
