Foreign body (FB) aspiration can be a life-threatening event. Although more common in children, FB aspiration can occur at any age. Symptoms related to FB aspiration range from coughing and shortness of breath to asphyxiation. Chest imaging can be nonspecific and infrequently identifies an FB. Herein, we describe a case of a 54-year-old male patient who aspirated an FB and experienced respiratory arrest. He failed to improve with conservative measures and required emergent bronchoscopy. He was found to have an FB in his proximal left mainstem bronchus that could not be removed using standard bronchoscopy and he was referred to our center for definitive care. We used a cryotherapy probe to remove the FB. We propose that cryotherapy is a useful tool to remove FBs that are soft and amenable to freezing.

pH-sensitive fluorescent proteins are widely used to study synaptic vesicle (SV) fusion and recycling. When targeted to the lumen of SVs, fluorescence of these proteins is quenched by the acidic pH. Following SV fusion, they are exposed to extracellular neutral pH, resulting in a fluorescence increase.

This paper presents a novel eco-friendly sensing material based on carbon paper (CP) volumetrically modified with a composite nanomodifier that includes functionalized poly(diallyldimethylammonium chloride) graphene (PDDA-G) and phytosynthesized gold nanoparticles (phyto-AuNPs). The functionalization of graphene was justified by Fourier-transform infrared spectroscopy. The phyto-AuNPs (d = 6 nm) were prepared by "green" synthesis with the use of strawberry leaf extract.
