High impact information on Materials Testing

• To investigate the effects of mechanical loading on GluR expression, we used a Materials Testing System (MTS) to apply 10 N sinusoidal axial compressive loads percutaneously to the right limbs (radius/ulna, tibia/fibula) of rats [1].
• In vitro and in vivo biocompatibility testing of Ti-6Al-7Nb alloy with and without plasma-sprayed hydroxyapatite coating [2].
• Human bone cell cultures in biocompatibility testing. Part II: effect of ascorbic acid, beta-glycerophosphate and dexamethasone on osteoblastic differentiation [3].
• Segmentally comminuted midisthmal fractures were simulated with use of sections of polyvinyl chloride pipe; each construct was cyclically loaded in compression with use of physiologically relevant loads in a materials testing machine at eight hertz [4].
• Effect of esterase on methacrylates and methacrylate polymers in an enzyme simulator for biodurability and biocompatibility testing [5].

Biological context of Materials Testing

• In vitro biocompatibility testing has clearly demonstrated that neutral pH, bicarbonate/lactate-buffered Physioneal solutions are superior to conventional solutions in preserving cell viability and function in cell populations that contribute to peritoneal homeostasis [6].

Anatomical context of Materials Testing

• Human bone cell cultures in biocompatibility testing. Part I: osteoblastic differentiation of serially passaged human bone marrow cells cultured in alpha-MEM and in DMEM [7].
• The testing methods follow guidance provided in the 9 CFR (bovine and porcine raw materials testing, and certain vaccine products) or Points to Consider documents (cell line characterization and evaluation of the majority of biologicals) [8].
• Further biocompatibility testing of silica-chitosan complex membrane in the production of tissue plasminogen activator by epithelial and fibroblast cells [9].
• METHODS: Cyclic loading was performed on 10 cadaveric shoulders through the LHB tendon on an MTS machine (Materials Testing System; MTS Systems Corp, Minneapolis, MN) at a peak force of 50 N (loading rate of 100 N/second) for 200 cycles [10].
• MATERIALS AND METHODS: Human fetal membrane explants were incubated with H1 or H2 relaxin for 48 hours and stretched until rupture in a materials testing machine [11].

Associations of Materials Testing with chemical compounds

• As a first part of a biocompatibility testing programme, in vitro corrosion tests were carried out on porous stainless steel AISI 316L and titanium compacts made of 100 microns thick fibres [12].
• Two other chemicals, benzo[a]pyrene (BP) and 5-nitroso-2,4,6-triaminopyrimidine (NTP), were also testing materials [13].
• Evaluating lyophilized human serum preparations for suitability as proficiency testing materials for high-density lipoprotein cholesterol measurement [14].
• The femurs were mounted and cyclically tested separately in coronal plane bending and sagittal plane bending on a materials testing system [15].
• The tensile and tear strength of carrageenan film from Philippines Eucheuma species were investigated using NEC tensilon universal-testing machine according to American Society for Testing Materials methods [16].

Gene context of Materials Testing

• INTERVENTION: Both-column fracture model with secondary congruence of the acetabular articular surface with respect to the femoral head was created and tested using Materials Testing Machine (MTS Systems Corp., Minneapolis, MN) and Fuji pressure-sensitive film (Sensor Products, Inc., East Hanover, NJ) [17].
• INTERVENTION: Hemipelvis and SI motion were analyzed on a Materials Testing System before and after creation of a vertically unstable APC III pelvic injury [18].
• Redesigned proficiency testing materials improve survey outcomes for prostate-specific antigen. A College of American Pathologists Ligand Assay Survey tool [19].
• Matrix effects on proficiency testing materials. Impact on accuracy of cholesterol measurement in laboratories in the nation's largest hospital system [20].
• Because stainless steel exhibits plastic behaviour with no sharp yield point, Apex self-drilling/self-tapping bone pins underwent incremental loading on an Instron materials testing machine [21].

Analytical, diagnostic and therapeutic context of Materials Testing

• Aluminium release from an alumina bioceramic was investigated parallel to standardized biocompatibility testing in an animal experiment [22].
