Background and purpose - Outcome after ligament reconstruction or tendon repair depends on secure tendon-to-bone healing. Increased osteoclastic activity resulting in local bone loss may contribute to delayed healing of the tendon-bone interface. The objective this study was evaluate effect bisphosphonate zoledronic acid (ZA) Methods Wistar rats (n = 92) had their right Achilles cut proximally, pulled through a tunnel distal tibia sutured anteriorly. After 1 week animals were randomized...
Bi2.5Y0.5Fe5O12 and Bi3Fe5O12 thin films were prepared on Gd3Ga5O12 substrates using a metal organic decomposition (MOD) method as magneto-optical indicators (MOI) to visualize the distribution of magnetic flux. Their structural properties studied. The Faraday rotations 15.5 μm/degrees at wavelength 524 nm for former 23.0 530 latter. We found that these by MOD suitable MOI, because their large rotation, in-plane anisotropy, extinct domain structures.
Children with cerebral palsy often have problems to support the body centre of mass, seen as increased ratio between excessive vertical ground reaction forces during weight acceptance and decreased below bodyweight in late stance. We aimed examine whether increasing ankle range motion through surgery restraining ankle-foot orthoses postoperatively would impact on force stance.Ground were recorded from 24 children bilateral 32 unilateral palsy, each measured walking barefoot before after...
Background: The calculation of remaining growth in children and the timing epiphysiodesis those with leg-length discrepancy (LLD) is most often done 4 methods: Green-Anderson, White-Menelaus, Moseley straight-line graph, multiplier methods. aims this study were to identify accurate method use bone age or chronological evaluate influence including inhibition calculations. Methods: One hundred ninety-one (10 17 years age) LLD who underwent surgical closure plate followed until skeletal...
Experimental studies indicate that non-steroidal anti-inflammatory drugs (NSAIDs) may have negative effects on fracture healing. This study aimed to assess the effect of immediate and delayed short-term administration clinically relevant parecoxib doses timing healing using an established animal model.A standardized closed tibia shaft was induced stabilized by reamed intramedullary nailing in 66 Wistar rats. A 'parecoxib immediate' (Pi) group received (3.2 mg/kg bodyweight twice per day)...
To analyze factors predicting mandibular cortical width (MCW) and index (MCI) in adult females males.
We developed a reflection-mode scanning near-field optical microscopy (SNOM) with an apertureless probe high special resolution and extinction ratio. Patterned Chromium film checker pattern deposited on quartz substrate was measured. In SNOM images, clear contrast between obtained, the spatial determined to be ~ 30 nm. A polarization property of scattered light from near field also investigated for both p- s-polarized incidence. The ratios were found larger than 100.
Using fluorescent microthermal imaging we have investigated the origin of "two-step" behavior in I-V curves for a current-carrying YBa2Cu3Ox superconducting bridge.High resolution temperature maps reveal that as applied current increases first step voltage corresponds to local dissipation (hot spot), whereas second is associated with onset global throughout entire bridge.A quantitative explanation experimental results provided by simple model an inhomogeneous superconductor, assuming hot...
Abstract Fixation failure with resulting non-union is the key complication after femoral neck fixation. It can be avoided by permitting dynamic compression and reducing rotation posterior tilt of head. To achieve this, a novel implant that features an interlocking plate three hook-pins (The Hansson Pinloc® System) was developed from original two hook-pins. Only enhanced torsional fixation modification reported. The purpose to compare biomechanical compressive bending stability modified in...
Abstract Objectives To analyze factors predicting mandibular cortical width (MCW) and index (MCI) in adult females males. Material Methods Data on 427 335 males aged 40-84 from The Tromsø study: Tromsø7 were used. T-score, age, menopausal status (for females), remaining teeth, periodontal analyzed linear logistic regression analyses as predictors of MCW MCI, respectively. Results the number teeth significantly predicted but not Standardized β coefficients 0.286, -0.231, 0.131, model...
PURPOSE OF THE STUDYTo improve the important torsional, bending and compressive stability in femoral neck fixation, locking plates have been latest contribution.However, increased strength by restricted fracture motion may come at expense of an altered load distribution failure patterns.Within plate technology, intermediate compression principally be achieved multiple sliding screws passing through a sideplate fixed to femur or connected interlocking not laterally, "en bloc" with plate.While...
