An innovative method of retrieval of the broken suction cannula tip during medical termination of pregnancy using a fibrobronchoscope during the coronavirus disease 2019 pandemic.

The breaking of the tip of the 'Karman cannula' inside the uterine cavity while performing suction curettage for missed abortion is an extremely rare phenomenon. Ideally, such foreign bodies should be removed using a hysteroscope under direct vision. In the absence of a hysteroscope, retrieval may be attempted using retrieving forceps either under ultrasonographic guidance or blindly.

Coi1 is a novel assembly factor of the yeast complex III-complex IV supercomplex.

The yeast bc1 complex (complex III) and cytochrome oxidase (complex IV) are mosaics of core subunits encoded by the mitochondrial genome and additional nuclear-encoded proteins imported from the cytosol. Both complexes build in the mitochondrial inner membrane various supramolecular assemblies. The formation of the individual complexes and their supercomplexes depends on the activity of dedicated assembly factors.
