Tarsal bone disintegration is characterised by fragmentation and progressive collapse of one or more tarsal bones. It occurs in 10% of leprosy patients, and is responsible for many severe foot deformities associated with this disease. The main cause is micro-traumata, but sensory impairment, sepsis and osteoporosis are predisposing factors. In this series of 400 consecutive patients the talus a...

I suggest that the distributions of species within a region reveal more about the processes that generate diversity patterns than does the co-occurrence of species at any given poi...

Slade and Vetter (1956) have shown that exposure to sonic oscillation of an aqueous suspension of a type 6 strain of Streptococcus pyogenes (Streptococcus haemolyticus) resulted in the solubilization of considerable quantities of the group-specific C-antigen, the type-specific M1antigen, and the cell wall constituent rhamnose. Several hours of oscillation resulted in the release into solution o...
