The interaction of bovine serum albumin ( BSA) and egg albumin with water solublephthalocyanine, cobalt (ΙΙ) 4, 4′ , 4′′, 4′′′- tetrasulfophthalocyanine ( CoTSPc) , has been studiedby the UV- Vis method at pH 7.0 and five different temperatures 20, 25, 30, 35 and 40°C. Theformation constants have been elucidated by using spectrophotometric titration and computerSQUAD program data refinement. Th...

the nutritional requirements of mammalian embryos changes throughout pre-implantation period, coincident with changes in the secretion of the female reproductive tract. therefore, it has been suggested that sequential culture media may support nutritional requirements for optimal growth of the mammalian embryos. in this study, we investigated the effect of two different concentrations (10 or 10...

infectious bovine rhinotracheitis is a highly contagious disease caused by the bovine herpes virus-1 (bohv-1), resulting in significant losses to livestock around the world. bohv-1 is a major pathogen of cattle, primarily associated with respiratory/genital tract infections and abortion. in the present study, we determined the presence of antibodies in 120 serum samples of cattle with the histo...

the purpose of this study was to evaluate the use of glass capillary micropipette (gcm) as a vessel forvitrification of bovine oocytes. cumulus-oocyte complexes (cocs) were obtained from slaughter-house andwashed 5 to 6 times in the washing medium (tcm-199 + 20% fbs) and randomly assigned to treatment andcontrol group. in the first step of vitrification, cocs were exposed to first vitrification...

the presence of antibacterial activity in bovine β-lactoglobulin and in α-lactalbumin hydrolysates was investigated. the plasmin-digest of β-lactoglobulin (pdβ) and of α-lactalbumin (pdα) were fractionated, using reversed phase high performance liquid chromatography. the antibacterial activity of β-lactoglobulin, α-lactalbumin, nisin, plasmin, pdβ and pdα were in vitro tested against pathogenic...

results based on our results, mab against recombinant erns was produced and reacted successfully with recombinant and natural antigens. conclusions with regards to the role of erns in the identification of pi animals, it appears that erns recombinant antigen and the specific monoclonal antibodies produced against it may be suitable for developing bvdv laboratory diagnostic assays. objectives er...

The suitability of mathematical models used to extract kinetic information from correlated data constitutes a significant issue in fluorescence correlation spectroscopy (FCS). Standard FCS equations are derived from a simple Gaussian approximation of the optical detection volume, but some investigations have suggested this traditional practice can lead to inaccurate and misleading conclusions u...

PURPOSE This study was designed to investigate an animal model of uveitis that resembles anterior uveitis in humans after immunization with iris-ciliary body antigen. METHODS Male Lewis rats 6 to 8 weeks of age were immunized with the buffer- and detergent-insoluble bovine iris-ciliary body antigen mixed with complete Freund's adjuvant and pertussis toxin. Antigen was digested with various pr...

Aim The study aimed to assess the nature of animal origin Staphylococcus aureus strains. The study has zoonotic importance and aimed to compare virulence between two different hosts, i.e., bovine and ovine origin. Materials and Methods Conventional polymerase chain reaction-based methods used for the characterization of S. aureus strains and chick embryo model employed for the assessment of v...
