Detection of infectious laryngotracheitis virus (Gallid herpesvirus-1) from clinically infected chickens in Egypt by different diagnostic methods

Infectious laryngotracheitis (ILT) disease is an acute highly contagious viral disease leading to massive economic losses to the national poultry industry. This study aimed to identify the most accurate and rapid diagnostic methods to rescue layer poultry farms from intense outbreaks in Egypt. Fifty pathological specimens were collected and subjected to virus isolation (VI), histopathology, dir...

Lmmunohistochemical Studies on T H E Interaction between Ehrlich Ascites Tumor Cells and Newcastle Disease Virus*,:~ by Alfred M. Prince,§ M.d., and Harold

Evidence has been presented which supports the hypothesis that Newcastle disease virus interacts with Ehrlich ascites tumor cells in a manner similar to the reactions of a virus with its susceptible host cells in a normal infection, except that replication of hemagglutinating, complement fixing, or infectious particles could not be demonstrated (2, 3). That virus penetrated into tumor cells was...

Differentiation Potential of Nestin (+) and Nestin (-) Cells Derived from Human Bone Marrow Mesenchymal Stem Cells into Functional Insulin Producing Cells

The feasibility of isolating and manipulating mesenchymal stem cells (MSCs) from human patients provides hope for curing numerous disease and disorders. Recent phenotypic analysis showed heterogeneity of MSCs. A nestin progenitor cell is a subpopulation within MSCs which plays a role in pancreas regeneration during embryogenesis. This study aimed to separate nestin (+) cells from human bone mar...

Transient expression of green fluorescent protein in radish (Raphanus sativus) using a turnip mosaic virus based vector

It is possible to use transgenic plants, as bioreactors, for the production of recombinant inexpensive chemicals and drug components. Transient gene expression is an appropriate alternative to stable transformation because it allows an inexpensive and rapid method for expression of recombinant proteins in plant tissues. In recent years, plant viral vectors have been increasingly developed as su...
