Nanoplastics trigger the aging and inflammation of porcine kidney cells.

Nanoplastics have now become a pervasive contaminant, being detected in various environmental media. However, our understanding of the specific toxicological effects of nanoplastics (NPs) on the kidneys remains unclear, which is a scientific problem that needs to be solved. To address this question, we employed two kidney cell lines as in vitro models to study the toxicological effects of NPs on porcine kidney cells.

Polystyrene nanoplastics exposure causes inflammation and death of esophageal cell.

Nanoplastics (NPs) are widely detected in food and drinking water, and human exposure to NPs is ubiquitous. The digestive tract is the main route of exposure to NPs in humans, and the esophagus is one of the main target organs for NPs exposure. However, the toxicological effects of polystyrene nanoplastics (PS-NPs) on the esophagus are not fully understood.

[Effect of acupoint injection with bone marrow mesenchymal stem cells on the blood flow in rats with hind limb ischemia].

Objective: To investigate the best injection method of the bone marrow mesenchymal stem cells (BM-MSCs) transplantation for the treatment of a rat model with hind limb ischemia.

Methods: Twenty four SD rats with hind limb ischemia were randomly divided into four groups: control group, model group, acupoint BM-MSCs injection group (API group) and thigh muscle BM-MSCs injection group (TMI group). The acupoints of "Sanyinjiao" (SP 6), "Housanli" (ST 36), "Zhaohai" (KI 6), "Huantiao" (GB 30) and "Yanglingquan" (GB 34) were selected for API group, and five non-acupoints were selected on gastrocnemius and adductor of ischemic hind limb for TMI group.
