High impact information on Compressive Strength

• Tibolone, 500 microg, resulted in 10% greater cortical strength of femur (p < or = 0.05) and 60% greater compressive strength of L4 (p < or = 0.05) compared with vehicle-treated OVX rats [1].
• Biomechanical testing demonstrated that PDGF administration increased the vertebral body compressive strength and femoral shaft torsional stiffness and resulted in a trend for enhanced femoral head shearing strength [2].
• Incorporation of 1.56% w/w CPP-ACP into the GIC significantly increased microtensile bond strength (33%) and compressive strength (23%) and significantly enhanced the release of calcium, phosphate, and fluoride ions at neutral and acidic pH [3].
• Withdrawal of PTH decreased the compressive strength and competence to control values [4].
• Compared with the control group, bone mineral density, compressive strength and stiffness were significantly higher in ibandronate-treated animals, whereas no changes occurred in strain or modulus of elasticity [5].

Biological context of Compressive Strength

• Effects of altered crystalline structure and increased initial compressive strength of calcium sulfate bone graft substitute pellets on new bone formation [6].

Associations of Compressive Strength with chemical compounds

• Tests conducted included: depth of cure as evaluated by hardness, water sorption, compressive strength, stress-strain behavior under slow compression, toothbrush abrasion, and wear by hydroxyapatite [7].
• Effects of phase transformations of silicas and calcium sulfates on the compressive strength of gypsum-bonded investments at high temperatures [8].
• Examination of the test for compressive strength applied to zinc oxide eugenol cements [9].
• Naproxen treatment partially prevented ovariectomy-induced loss or less gain in BMD, in a significant manner, in the femoral neck cortical area, and also in L1 compressive strength and stiffness [10].
• Addition of inorganic fillers to poly(methyl methacrylate) increased the compressive strength but decreased the transverse strength [11].

Gene context of Compressive Strength

• Parathyroid hormone (1-34) increases vertebral bone mass, compressive strength, and quality in old rats [12].
• Dispersion of 5 wt % of rod-like hydroxyapatite and CaTiO3 powders with alpha-TCP cement containing 5 wt % gelatin gel increased the compressive strength after 1 week from 14.1 to 31.3 and 34.8 MPa, respectively [13].
• The hardening properties of calcium phosphate cements in the CaHPO4-alpha-Ca3(PO4)2 (DCP-alpha-TCP) system have been investigated with interest focused on the compressive strength and microstructure development [14].
• Composites containing BSA developed compressive strengths twice that of the original cement at protein concentrations of 13-25% by weight [15].
• A significant increase in compressive strength was, however, observed for H12 over time [16].

Analytical, diagnostic and therapeutic context of Compressive Strength

• Bone fluoride levels ere determined with the ion specific electrode, the mineral density with the gamma ray attenuation method, and the compressive strength with a strain transducer [17].
• Understandably, the presence of chitosan/beta-TCP microspheres in the prepared composites reduced the ultimate compressive strength and bending strength [18].
