Introduction Given the limitations of meniscectomy and meniscal repair, allograft meniscus replacement is gaining momentum. Allografts incorporate into the joint and relieve pain in the short term, but arthroscopic or MRI evaluation reveals evidence of arthrosis and allograft tearing [1]. Research into alternative preservation methods is needed since current processes do not deter enzymatic deg...

Glutaraldehyde is a potential sensitizer and has been implicated in the literature as a cause of respiratory irritation and asthma among health care workers. In order to evaluate the effect of work practices and general ventilation system on employees' peak exposure to glutaraldehyde, 42 breathing zone personal air samples were taken in five hospitals. In addition, work practices were observed ...

This work was aimed at immobilization, characterization, and utilization of chitinase from Kurthia gibsonii Mb126. Immobilization Mb126 on glutaraldehyde treated chitosan carried out with immobilization yield 106%. The optimal factors the technique such as concentration glutaraldehyde, concentration, time were evaluated. After optimizing process parameters (Glutaraldehyde 4%, conc. 60mg, 30min....

Therapeutic vaccination of B cell lymphoma patients with tumor-specific Ig (idiotype, or Id) chemically coupled to the immunogenic foreign carrier protein keyhole limpet hemocyanin (KLH) using glutaraldehyde has shown promising results in early clinical trials, and phase III trials are underway. However, glutaraldehyde Id-KLH vaccines fail to elicit anti-Id immune and clinical responses in many...

The carotid bodies from control, reserpine-treated, and hypoxia-treated hamsters were fixed with phosphate-buffered glutaraldehyde and osmium tetroxide, s-Collidine-buffered osmium tetroxide, or phosphate-buffered glutaraldehyde followed by potassium dichromate incubation. Following glutaraldehyde-osmium tetroxide fixation no differences in density or population of the electron-opaque granules ...

Polyvinyl alcohol (PVA) and pectin blends were used to entrap α-amylase (Termamyl) using glutaraldehyde as a cross-linker. The effect of glutaraldehyde concentration (0.25, 0.5, 0.75, 1.0, and 1.25%) on the activity of the immobilized enzyme and rate of enzyme released was tested during a 24 h period. Characteristics of the material, such as scanning electron microscopy (SEM), tensile strength ...

Purpose: The objective of the present study was to evaluate the effect of ultraviolet ray combined with immersion method on the disinfection of silicone impression materials. Methods: Forty eight silicone impressions were rinsed by flushing water and then completely dried. Impressions were randomly divided into A and B groups (n=24). In group A, serum sample with positive hepatitis B virus was ...

Immunohistochemical approaches have been widely used in the localization and quantification of advanced glycation end-products (AGEs). Traditional approaches for production of anti-AGE antibodies use cross-linkers such as 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC) to conjugate the AGE antigen to the carrier protein. However, these approaches often fail to produce antibodi...
