The final step of 40S ribosomal subunit maturation is controlled by a dual key lock. [PDF]
Elife, 2021 Preventing premature interaction of preribosomes with the translation apparatus is essential to translation accuracy. Hence, the final maturation step releasing functional 40S ribosomal subunits, namely processing of the 18S ribosomal RNA 3’ end, is ...

Two-piece obturator using “lock-and-key” mechanism
The Journal of Indian Prosthodontic Society, 2017 This paper describes a method used for the fabrication of a two-piece denture obturator for a patient who had surgical removal of the premaxilla due to squamous cell carcinoma. The patient had been wearing a two-piece obturator but encountered difficulty

Colloids with key-lock interactions: non-exponential relaxation, aging and anomalous diffusion [PDF]
Physical review. E, Statistical, nonlinear, and soft matter physics, 2007 The dynamics of particles interacting by key-lock binding of attached biomolecules are studied theoretically. Experimental realizations of such systems include colloids grafted with complementary single-stranded DNA (ssDNA), and particles grafted with ...

An Unusual Transorbital Penetrating Injury by House-key (lock): A Case Report with a Small Review of Literature. [PDF]
J Clin Diagn Res, 2015 Penetrating injuries of the brain are quite uncommon, comprising approximately 0.4% of all head injuries. In our case, a four-year-old boy who fell forward on a house-key (lock) accidentally while playing with some other children sustained a left sided ...
