Grill brushes are ubiquitous tools used at backyard barbeques every summer. However, thin wire bristles can dislodge, become embedded within food, and inadvertently ingested. Here, we present a case report describing the computed tomography scan localization of a stray ingested wire bristle and the use of intraoperative fluoroscopy with 14-gauge needles to triangulate the exact location of this thin object.

In order to apply the rigid biodegradable PLA material for flexible toothbrush bristle products, in this paper, Poly(lactic acid) (PLA) and thermoplastic polyurethane elastomer (TPU) blends (TPU/PLA composites), with a mass ratio of 80:20, were prepared by the melt-blending method to achieve toughening modification. Infrared spectroscopy, scanning electron microscopy, differential scanning calorimetry and low-field nuclear magnetic resonance were used to investigate the effect of the compatibilizer, Maleic anhydride grafted polypropylene (PP--MAH), on the compatibility of the blends, and the effect of melamine on the flame retardant properties of the blends was further investigated. The results demonstrated that 3% PP--MAH had the best compatibility effect on PLA and TPU; the TPU/PLA composites have a better macromolecular motility and higher crystallization capacity in the amorphous regions through the physical and chemical action by using PP--MAH as a compatibilizer.

Objective: Inadvertently ingested grill brush bristles can lodge in various locations and lead to a variety of injuries. They can also be difficult to identify and remove. Our primary objective was to perform a systematic review of cases reported in the literature, with analysis of trends in clinical presentation and success of diagnostic modalities and treatment approaches.

The shape and attitude (S&A) of the electrode wire are important characteristics of micro coreless motor winding. The purpose of this paper is to present the design of a robotic micro-manipulation system for micro wire carding with arbitrary S&A, which can be used as the pretreatment system for wire micro-gripper systems. The system is based on the principle of flexible carding, and uses nylon, bristle, nanometer-silk and wool as materials for the brushing micro-manipulator. Read More
