Molecular modeling and co-expression analysis of human stem cell factor as fusion partner to granulocyte colony stimulating factor for improving their bioactivity.

Human granulocyte colony stimulating factor (hG-CSF) is an expensive hematopoietic growth factor that is clinically used in human for the treatment of neutropenia in diseases such as AIDS, aplastic anemia, myelodysplastic syndrome and congenital or chemotherapy-induced neutropenia. Here, through a computational biology approach, we show that human stem cell factor (hSCF) could be a better fusion partner than human thyroid peroxidase (hTPO), human erythropoietin (hEPO) and human interleukin-3 (hIL3) for co-expression with hG-CSF. Molecular modeling of hG-CSF-hSCF fusion protein with hG-CSF and hSCF receptors showed that binding of fusion protein with human granulocyte colony stimulating factor receptor (hG-CSFR) did not inhibit its binding to human stem cell factor receptor (hSCFR) and vice versa.

Comparative evaluation of optical coherence tomography in glaucomatous, ocular hypertensive and normal eyes.

Background: To correlate the findings of optical coherence tomography (OCT) evaluation of retinal nerve fiber layer (RNFL) thickness with visual field changes in glaucomatous, ocular hypertensive and normal eyes.

Materials And Methods: Thirty consecutive normal, 30 consecutive ocular hypertensive and 30 consecutive glaucomatous eyes underwent a complete ophthalmic examination, including applanation tonometry, disc evaluation, (30-2) Humphrey field analyzer white on white (W/W) perimetry and short- wavelength automated perimetry. Thickness of the RNFL around the optic disc was determined with 3.
