Bovine embryonic stem cells are of potentially big value in transgenic research and studies of lineage commitment and development. Nevertheless, key aspects of the establishment of bovine embryonic stem cells such as the identification of specific pluripotency markers need to be clarified to achieve successful results. Bovine blastocysts were produced in vitro and cultured for 8 days up to the ...

Bovine papilloma antigen detected by fluorescent antibody was correlated with the appearance of infectious virus and with epithelial hyperplasia and hyperkeratinization in the developing bovine cutaneous papilloma. Neither antigen nor infectious virus was found in the earliest stages of growth characterized by connective tissue pro liferation and by little or no epithelial change. The cellular ...

Glycopeptides with TN antigen (GalNAc)Ser/Thr and T-antigen structures (beta Gall-3GalNAc)Ser/Thr, described as tumor-associated antigens, were synthesized and coupled to bovine serum albumin. Alternatively, synthetic methods for the construction of beta-anomeric analogues of the TN and T-antigen glycopeptides were developed, aiming at antigenic structures having a varied stereochemistry of the...

An in vitro system has been used to demonstrate that glass-adherent mouse peritoneal cells can be activated to kill intracellular Listeria monocytogenes by antigen-stimulated T-lymphocytes derived from immunized mice. The soluble products of such stimulated lymphocyte cultures could only be shown to similarly activate peritoneal cells if the antigen used in both the immunization and lymphocyte ...

In 1985 a patient was described whose persistent polyarthritis was found to be aetiologically linked to rubella virus infection through the detection of repeated maximal synovial lymphocyte proliferative responses to rubella virus antigen and by isolation of rubella virus from her synovium. Follow up over the succeeding seven years has shown continuing chronic polyarthritis and persistent synov...

Background and Aim: Recent information on the occurrence of bovine hypodermosis in Kazakhstan is limited to results a few clinical studies northern eastern regions. A first serological study aimed obtain more data its geographical distribution estimate prevalence this country. Materials Methods: Serum samples collected from 891 dairy cows 30 farms eight Kazakh provinces during winter season 201...
