results daily administration of 50 mg/kg ptx (groups 1 and 2) decreased the high stress load in repairing osteotomized femurs when compared with the control group. the highest dose of ptx (200 mg/kg) significantly increased the high stress load when compared with the control group (p = 0.030), group 1 (p = 0.023), group 2 (p = 0.008), and group 3 (p = 0.010), per the lsd findings. materials and...

The purpose of this study was to reconstruct the early phase of scientific research conducted at the Department of Biomechanics of the College of Physical Education and since 1972 at the University School of Physical Education in Poznań, with special attention paid to the works on biomechanics of rowing, carried out as part of the Ministerial Project PR 105 entitled The effectiveness of trainin...

BACKGROUND Double-leg forward or drop-jump landing activities are typically used to screen for high-risk movement strategies and to determine the success of neuromuscular injury prevention programs. However, research suggests that these tasks that occur primarily in the sagittal plane may not adequately represent the lower extremity biomechanics that occur during unilateral foot contact or non-...

abstract objective: the aim of this study was to evaluate the efficacy of antibiotic-loaded bone cement in controlling local infection and in regard to its physical characteristics, elastic modulus, and tensile strength in-vitro. methods: acrylic bone cement, based on polymethylmethacrylate (pmma) was mixed with the powder form of three antibiotics, i.e., gentamicin, tobramycin, and cefuroxime ...

the cadaver spine motion segment behavior under torsional load was evaluated with the disc intact, with partial anterior discectomy and with spacer insertion. the results of this study explain how anterior lumbar discectomy and interbody fusion (alif) affects the torsional stability of the motion segment. the pseudarthrosis rate of the anterior lumbar discectomy and interbody fusion (alif) is k...
