ABSTRACT
Twenty-two Flexor Digitorum Superficialis (FDS) muscles from 18 cadavers were dissected to find the "Optimal Injection Site" (OIS) for botulinum toxin injections to individual bellies of FDS. Coordinates are given as a percentage of the distance along a landmarking line from the medial epicondyle to the pisiform and in millimetres (mm) lateral to it. The OIS were: FDS2: 72%, 14 mm; FDS3: 54%, 17mm; FDS4: 49%, 7mm; FDS5: 76%, 6mm. OIS measurements guide the electromyographer to localize the targeted muscle belly.

Purified cell walls from Bacillus subtilis were repeatedly suspended in 5 mM CuCl2 and, after removing unbound Cu, were suspended in 1% (v/v) HNO3 to release bound Cu. The walls were then regenerated by washing in H2O. After five cycles, copper binding actually increased slightly, probably due to enhanced exposure of binding sites in the walls. Thus bacterial walls may be used repeatedly for metal removal during bioremediation of heavy metal pollution.
