Micro‐ and nanoplastics in gastrointestinal disorders: Mapping the translational gap between exposure, biomonitoring, and pathogenic mechanisms

open access: yesBMEMat, EarlyView.
This review highlights critical “translational gaps” in understanding micro‐ and nanoplastics impacts on gastrointestinal diseases, bridging exposure, detecting, and mechanistic toxicology. Abstract Micro‐ and nanoplastics (MNPs) have become pervasive environmental contaminants with increasing evidence linking them to adverse health outcomes.

Hawaii Deep Water Cable (HDWC) Program : cable overloadability study

open access: yes, 1986
The scope of this study is to determine the short term overload capability of Cable No. 116 in the event of the loss of one pole of the dc transmission system. Such a loss would result in the loss of 250 MW of transmitted power. This exceeds the spinning

Anchored but not safe: Rare but serious mechanical complications from peritoneal dialysis catheter suture fixation

open access: yesUroPrecision, EarlyView.
Abstract Background Peritoneal dialysis (PD) catheter fixation techniques are frequently employed to minimize migration and optimize dialysate flow. While mechanical complications of PD catheters are well recognized, adverse events directly attributable to anchoring sutures are rarely described. We report two patients with end‐stage renal failure (ESRF)
