Characterization, analysis, and application of fabricated Fe3O4-chitosan-pectinase nanobiocatalyst.

The investigation on fabrication of Fe3O4-chitosan-pectinase nanobiocatalyst was performed by covalently binding the pectinase onto carboxyl group activated chitosan-coated magnetic nanoparticles (CMNPs). The morphological and size distribution analysis of the different magnetic nanoparticles (MNPs) was done using transmission electron microscopy (TEM), and the average diameter was 11.07 ± 3.

Fabrication, characterization and application of pectin degrading Fe3O4-SiO2 nanobiocatalyst.

The covalent binding of pectinase onto amino functionalized silica-coated magnetic nanoparticles (CSMNPs) through glutaraldehyde activation was investigated for nanobiocatalyst fabrication. The average particle size and morphology of the nanoparticles were characterized using transmission electron microscopy (TEM). The statistical analysis for TEM image suggests that the coating and binding process did not cause any significant change in size of MNPs.

Synchronous papillary thyroid carcinoma and primary hyperparathyroidism: diagnosis and management issues.

The occurrence of a papillary thyroid carcinoma in a patient with primary hyperparathyroidism is rare. Awareness of this condition will enable clinicians to evaluate for possible thyroid pathology in patients with primary hyperparathyroidism. Both of these endocrine conditions could then be managed with a single surgery involving concomitant resection of the thyroid and parathyroid glands.
