Corneal Absorption and Anterior Chamber Pharmacokinetics of Dipeptide Monoester Prodrugs of Ganciclovir (GCV): In Vivo Comparative Evaluation of These Prodrugs with Val-GCV and GCV in Rabbits

Journal of Ocular Pharmacology and Therapeutics, 2006
The overall aim of this study was to evaluate the corneal absorption of dipeptide monoester prodrugs of ganciclovir (GCV) and compare these results with L-valine-GCV and GCV. Another aim was to evaluate the pharmacokinetics of these prodrugs in aqueous humor.A well was placed on the cornea of anesthetized New Zealand albino rabbits with linear probes ...

Characterization of the Escherichia coli gcv operon

Gene, 1994
The nucleotide (nt) sequence of the Escherichia coli gcvP gene was determined. The polypeptide deduced from the DNA sequence has an M(r) of 104,375 (957 amino acids). In a minicell system, gcvP encodes a polypeptide that migrates at 93.3 kDa on sodium dodecyl sulfate-polyacrylamide gels.

Subtherapeutic ganciclovir (GCV) levels and GCV‐resistant cytomegalovirus in lung transplant recipients

Transplant Infectious Disease, 2014
AbstractBackgroundCytomegalovirus (CMV) infection results in significant morbidity and mortality in lung transplant recipients. Ganciclovir (GCV) has dramatically reduced complications caused by CMV infections. Unfortunately, GCV resistance is identified in 5–10% of CMV‐infected patients.

On the choice of tuning parameters for use with Robust GCV, Modified GCV and the Discrepancy Principle in the inversion of ARXPS data

Journal of Electron Spectroscopy and Related Phenomena, 2014
Abstract Composition depth profiles were extracted from simulated ARXPS data using regularization, with the regularization parameter determined by three different methods (Robust GCV, Modified GCV, and the Discrepancy Principle) that require tuning parameters.

GCV for Tikhonov regularization by partial SVD

BIT Numerical Mathematics, 2017
A new approach for the bounding of the Generalized Cross Validation (GCV) function is proposed in this paper. The developed approximation method is based on the observation that for many linear discrete ill-posed problems with a large matrix, it is quite inexpensive to determine the upper and lower bounds for the GCV function.

Image denoising by using PDE and GCV in tetrolet transform domain

Engineering Applications of Artificial Intelligence, 2016
The proposed algorithm, which uses partial differential equations (PDE) and generalized cross validation (GCV) theory in the tetrolet transform domain, is used to reduce the noise in an image. Tetrolet transform is applied to decompose the noisy image and GCV theory is used to determine the optimal denoising threshold in the tetrolet transform domain ...

Application of GCV in Geophysical Diffraction Tomography

69th EAGE Conference and Exhibition incorporating SPE EUROPEC 2007, 2007
P032 Application of GCV in Geophysical Diffraction Tomography E. Santos (CEFET/BA and Stanford University) & A. Bassrei* (Federal University of Bahia) SUMMARY Since inverse problems are usually ill-posed it is necessary to use some method to reduce their deficiencies. The method that we choose is the regularization by derivative matrices.

Surface fitting using GCV smoothing splines on supercomputers

Proceedings of the 1995 ACM/IEEE conference on Supercomputing (CDROM) - Supercomputing '95, 1995
The task of fitting smoothing spline surfaces to meteorological data such as temperature or rainfall observations is computationally intensive. The Generalized Cross Validation (GCV) smoothing algorithm is O(n 3) computationally, and memory requirements are O(n 2).
