In a preliminary study carried out in a simple field laboratory in Bandar-Abbas, southern Iran, five isolates of P. falciparum collected from the patients was cultured in RPMI 1640 medium with human s...
A COMPARISON OF PULLOUT STRENGTH OF PEDICULAR SCREWS BETWEEN DIFFERENT METHODS OF SCREW INSERTION IN POSTERIOR FIXATION OF THORACIC SPINE
Pedicle screw spine thoracic intratransverse process pullout strength
2009/12/18
Pedicle screws provide rigid fixation for instabilities in the lumbar and lumbosacral spine. Anatomical consideration and potential risk of neurologic complications are the reasons to hesitate using p...
Influence of lateral-oblique cyclic loading on abutment screw loosening of internal and external hexagon implants
Screw loosening Preload Abutment screw
2009/9/11
To date, there is no evidence that internal anti-rotation configurations are better than external ones. The purpose of this study was to evaluate the effect of eccentric cyclic loading on abutment scr...
