Abstract Avian infectious bronchitis (IB) is a highly contagious disease caused by virus (IBV), coronavirus of domestic fowl. IB major concern in the poultry industry, causing worldwide economic losses through decreased egg production and quality increasing chicken's susceptibility for secondary bacterial infections, particularly Escherichia coli . In this study, anti‐IBV activity cathelicidins...

Intraperitoneal administration of bovine albumin sharply increases glomerular permeability to hemoglobin in the rat kidney. In addition, bovine albumin "saturates" the tubular absorption mechanism and inhibits the tubular absorption of subsequently administered hemoglobin. Egg white, ovalbumin, and ovomucoid, in contrast, do not produce significant changes in glomerular permeability to hemoglob...

Background: Lactoferrin is a glycoprotein with a molecular weight of 80 kDa, as a member of the transferring family. In recent investigations the important biological properties such as anti microbial, antiviral and anticancer activity of lactoferrin were studied. In the present study, the effect of antitumor induced by lactoferin was evaluated on stomach cancer cell AGS. Materials and Methods...

Thrombomodulin (TM) is a glycoprotein localized mainly on endothelial cell surfaces, and is a major regulator of vascular thromboresistance. The entire open reading frame of canine TM cDNA comprises 1737 bp, encoding 578 amino acid residues. Comparison of the deduced amino acid sequence from canine TM with those of human, mouse, rat, rabbit and bovine (partial) TM sequences revealed 73.1%, 69.1...

An experimental vaccine prepared from influenza virus strains propagated in bovine kidney cell cultures, purified by zonal centrifugation, and further treated with ether was studied in man for the incidence of clinical reactions and hemagglutination-inhibition antibody levels induced. The results were equivalent to those obtained in a simultaneous study made with a commercially licensed influen...

Extracellular vesicles (EV) awakened interest in the research on mesenchymal stromal cells by exploring their paracrine effects. However, many isolation protocols use bovine serum albumin (BSA) during the preparation of the EV. Therefore, we produced 'sham' BSA-EV and tested them in comparison to EV derived from mesenchymal stromal cells (MSC-EV). We found that BSA-EV did not express MSC-specif...

Some Dorema species are used in Persian traditional medicine. In the present study the total extract from the roots of Dorema hyrcanum Koso-Pol. was investigated for its in vitro (pLDH assay) and in vivo (Peters’ 4-days suppressive test) antiplasmodial effects and assessed for cytotoxicity against the normal cell line MDBK (MTT test). The IC50 values for a chloroquine- sensitive (3D7) and a chl...

The acid protease which is activated by ATP and which catalyzes production of fragments of parathyroid hormone similar to those produced in vivo was shown to be cathepsin D. Purified cathepsin D from bovine kidney and spleen is activated by ATP and other nucleoside triphosphates, and to a much lesser extent by nucleoside diphosphates and pyrophosphate. These findings suggest that cathepsin D ma...

we report a case of membranoproliferative glomerulonephritis (mpgn) with igmκ light chain deposits in a patient with chronic hepatitis c infection and simultaneous onset of monoclonal igmκ gammopathy with concurrent small b-cell lymphoproliferative disease. the patient presented with hepatosplenomegaly and a uremic state that necessitated dialysis without any clinical signs of systemic disease ...

spermatogonial stem cell (ssc) technologies provide multiple opportunities for research in the field of biotechnology and regenerative medicine. the therapeutic use of embryonic stem cells (escs) is restricted due to severe ethical and immunological concerns. therefore, we need a new pluripotent cell type. despite well-known role of germ cells in the gametogenesis, some facts apparently show th...
