Nonalcoholic fatty liver disease (NAFLD) is one of the main causes of chronic liver disorders following liver transplantation. The prorenin receptor (PRR) plays a role in glucose and lipid metabolism, and the hepatic dysregulation of PRR is associated with the upregulation of several molecular pathways, such as the mammalian target of rapamycin (mTOR) and Peroxisome proliferator-activated receptor (PPAR) that promotes hepatic lipogenesis and leads to lipid accumulation in hepatocytes by upregulation of lipogenic genes. PRR inhibition leads to a reduction in the hepatic expression of sortilin-1 and low-density lipoprotein receptor (LDLR) levels and down-regulation of pyruvate dehydrogenase (PDH) and acetyl-CoA carboxylase (ACC) and reduces fatty acids synthesis in hepatocytes.

- This study explored how graphene oxide (GO) and magnetic GO (MGO) nanosheets perform in anaerobic digestion (AD) of municipal sludge over 230 days, focusing on their impact under different organic loading rates (OLRs).
- At lower OLRs (2.6 and 3.4 g COD/L/day), GO and MGO did not affect AD performance, but at a higher OLR (5.2 g COD/L/day), they maintained stable biogas yields when control systems failed.
- The enhancements were linked to improved conductivity and microbial interactions, and the study validated biochemical methane potential (BMP) assays as effective forecasting tools for AD outcomes, highlighting the benefits of GO/MGO for improving AD system stability
Article Synopsis
- Researchers are focused on developing highly porous materials like cryogels for electromagnetic interference (EMI) shielding that primarily absorb, not reflect, electromagnetic waves.
- They created various graphene oxide (GO)-based cryogels using different fabrication methods and treated them to improve electrical conductivity.
- The study found distinct behaviors in shielding effectiveness: chemically-crosslinked cryogels mostly reflected EM waves while worm-like cryogels absorbed them better due to their unique porous structures, providing insights on how to design improved EMI shields.
This study evaluated anaerobic co-digestion as a promising strategy for managing organic-contaminated waste streams generated from nanomaterial synthesis. The novel approach enabled precise quantification of organic content, efficient biomethane recovery, and a sustainable redirection of ethanol-contaminated graphene oxide (GO) dispersions. The proposed method achieved high accuracy (93-97%) in detecting organic content in ethanol-contaminated GO dispersions, significantly outperforming the conventional total chemical oxygen demand (tCOD) method, which only reached 75-77% accuracy.
