Introduction: Prolonged obstruction in UPJO would lead to kidney destruction. It is important to find a non-invasive biomarker for early detection of renal impairment before definitive treatment for UPJO. In this study, we aim to evaluate the role of urinary cytochrome c and caspase-3 as a novel biomarker to predict renal function impairment in a UPJO model in Wistar rats.
Methods: Twenty-five male Wistar rats were separated into 3 groups. Group I consists of 5 rats without any treatment or model, group II consists of 5 rats (sham group), and group III consists of 15 rats with the unilateral partial ureteral obstruction model. After 4, 15, and 21 days of observation, the urine was collected and rats were sacrificed to collect the glomerular count in the kidney. Measurement of cytochrome c and caspase-3 was done using the ELISA method, while the glomerular count was done using a light microscope. Data were analyzed using factorial repeated measures ANOVA test and correlation test with Pearson and processed using SPSS version 20.0.
Results: The UPJO group has a significant increase in cytochrome c concentration and caspase-3 concentration compared to the control group and sham group (<0.05). There was a significant decrease in the normal glomerulus count of the UPJO group (<0.05). There was a significant relationship between the decrease in glomerulus count with the concentration of cytochrome c and caspase-3 in the UPJO group.
Conclusion: There was a significant relationship between the decrease in glomerulus count with the increase in the concentration of cytochrome c and caspase-3 in the UPJO group.

Background: Alzheimer's disease (AD) is a neurodegenerative disorder characterized by senile plaques, amyloid-beta (Aβ), and neuroinflammation. The key targets in the treatment of AD are inhibiting the production of amyloid-beta (Aβ), sphingomyelinase, and inflammation. Among the mechanisms, sphingolipids (specifically Ceramides) are recognized as distinctive mediators associated with the pathology of AD.

Article Synopsis
- Intimal hyperplasia (IH) is a major issue in vascular interventions, and this study investigates the role of gangliosides GA2 in its development.
- Researchers found that GA2 levels were significantly higher in atherosclerotic mouse aortae and plasma, and injecting GA2 worsened IH by interacting with macrophages.
- The study reveals that GA2 activates caspase-4 and promotes pyroptosis in macrophages, suggesting a new mechanism for IH that could lead to potential diagnostic and treatment strategies.

Background: A precise observation is that the cervix's solid tumors possess hypoxic regions where the oxygen concentration drops below 1.5%. Hypoxia negatively impacts the host's immune system and significantly diminishes the effectiveness of several treatments, including radiotherapy and chemotherapy.

Background: The tumor suppressor wild-type p53 is known for its role in inducing apoptosis in tumor cells. This study investigated the relationship between wild-type p53 and protein phosphatase 1 (PP1) and caspase in promoting apoptosis of breast cancer cells.
Methods: Human breast cancer cell lines MCF-7 and MDA-MB-231 obtained from the American Type Culture Collection were used in this study.

Bisphenol A (BPA) has been commonly used in various consumer products, including water bottles, food containers, and canned food linings. However, there are concerns about its potential toxicity to human health, particularly its impact on the liver and kidneys. The objective of this research was to investigate the potential ameliorative effects of 18β-glycyrrhetinic acid (GA) against BPA-induced hepatotoxicity and nephrotoxicity in rats.
