As most of polypeptides are marginally stable, a mild formulation procedure would be beneficial for the activities of these drugs. The objective of the present study was to develop a novel pH-sensitive nanoparticle system that was suitable for entrapment of hydrophilic insulin but without affecting its conformation.

Methylmethacrylate stabilization of the cervical spine.
The Journal of Bone & Joint Surgery, 1984Several conditions that lead to instability of the cervical spine require surgical fixation, and on occasion that procedure may include the use of methylmethacrylate. In the series that we are reporting, there were eighteen patients with malignant disease, seventeen with fractures, twelve with rheumatoid arthritis, and five with osteoarthritis.

The fracture stress of poly(methylmethacrylate)
Materials Science and Engineering, 1977Abstract A theory has been developed to predict the fracture stress of single edge notched poly(methylmethacrylate) (PMMA) tensile specimens from crack propagation data. Good agreement has been found between measured values of fracture stress and the fracture stresses predicted using the theory.

Experimental fixation of fractures of the femur with methylmethacrylate
The Journal of Bone & Joint Surgery, 1975Use of a simple method for injection of cooled methylmethacrylate into the distal part of the femur through the canal of a Küntscher rod to stabilize distal femoral-shaft fractures proved experimentally to greatly increase the torsional stability at the fracture site.

The Effect of Methylmethacrylate on Fracture Healing
Clinical Orthopaedics and Related Research, 1976Fractures were created in the femur of dogs by dividing the midshaft with an airdriven saw. Immobilization was achieved with a four-hole compression plate. No methylmethacrylate supplementation was used in the control groups. In the three experimental groups methylmethacrylate was added to the internal fixation by placing it on the endosteal ...

Polymerization of methylmethacrylate in presence of tetramethylthiuramdisulphide
European Polymer Journal, 1978Abstract The effect of TMTD on the polymerization of methyl methacrylate was studied. The plot of R P vs [TMTD] 1 2 shows a maximum ascribed to participation of TMTD-radicals in cross (P′ + RS′) and mutual-termination (RS′ + RS′). The total polymerization rate is then well expressed by a derived relation. Study of the influence of

Efficient removers for poly(methylmethacrylate)
Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 2002As nanotechnology approaches molecular scales, issues of surface contamination by unremoved resists will play an important role in device fabrication. Electron beam lithography of polymethylmethacrylate (PMMA) resist is still among the most widely used nanofabrication techniques, so it is relevant to study its residual contamination on both exposed and

Tobramycin-Impregnated Methylmethacrylate for Mandible Reconstruction
Archives of Otolaryngology - Head and Neck Surgery, 1992Reconstruction of the mandible to restore continuity following resection is described in four cases using a tobramycin-impregnated methylmethacrylate implant fabricated at the time of surgery. Methylmethacrylate has excellent biocompatibility and strength and has been used in surgery for over 20 years. The technique uses readily available materials and

Physical adsorption on poly(methylmethacrylate)
Journal of Colloid Science, 1965Abstract Isotherms for the adsorption of nitrogen and argon on poly(methylmethacrylate) were obtained at three temperatures over a pressure range from a few microns to the saturated vapor pressure of the adsorbing gas. Differential and integral enthalpies and entropies were calculated and indicate a heterogeneous surface with adsorption energies ...
