Cloning And Expression Of Bacteriophage T4 Lysozyme Gene (Gene E) In Escherichia Coli Via Pcr Amplification, Ali̇ İrfan Güzel, Numan Özcan, Hali̇l Kasap

Turkish Journal of Veterinary & Animal Sciences

Lysozyme (EC 3.2.1.17) is an enzyme that catalyzes the hydrolysis of \beta(1-->4) glycosidic bonds between N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM), which are present in peptidoglycan heteropolymers of the prokaryotic cell wall. The purpose of this study was the cloning and expression of the bacteriophage T4 lysozyme gene (gene e) via PCR amplification in Escherichia coli using the pUC18 and pRS416 vectors. PCR amplification is carried out by using the primers having Bam HI recognition sites at their 5' ends. After digesting the vectors and PCR product with Bam HI endonuclease, two recombinant plasmids were constructed by ligation reaction …

Introduction Of The Precise Ts Measurement For Fisheries Acoustics, Kouichi Sawada, Yoshimi Takao, Yoichi Miyanohana, H. Tuncay Kinacigi̇l Jan 2002

Introduction Of The Precise Ts Measurement For Fisheries Acoustics, Kouichi Sawada, Yoshimi Takao, Yoichi Miyanohana, H. Tuncay Kinacigi̇l

Turkish Journal of Veterinary & Animal Sciences

Two methods to measure target strength (TS) are introduced and compared with each other. One is the suspension method, and the other is the split-beam method. Each of them is representative of control and in situ methods, respectively. In addition, a morphological investigation of a swimbladder in a pressure tank, and the development of an instrumented package of acoustic and optical systems, are also introduced. The former is to reveal the degree of TS variation by the vertical movement of fish, and the latter is to obtain precise TS and fish behavior by the echo trace analysis method.

Expression Of Subunits Of Ampa-Type (Ionotropic) Glutamate Receptors In The Rat Spinal Cord, Mümtaz Nazli, Zafer Soygüder, Ahmet Çarhan Jan 2002

Expression Of Subunits Of Ampa-Type (Ionotropic) Glutamate Receptors In The Rat Spinal Cord, Mümtaz Nazli, Zafer Soygüder, Ahmet Çarhan

Turkish Journal of Veterinary & Animal Sciences

The distribution of ionotropic glutamate receptor subunits (GluR1-4), considered a-amino-3-hydroxy-5-methyl-4-isaxole propionic acid type (AMPA-type), was investigated in the rat spinal cord by immunocytochemistry. Different distributions of the AMPA-type glutamate receptor subunits were observed in the spinal cord. Immunolabelling with antibodies to both GluR1 and GluR2/3 revealed intensive staining in the dorsal horn, while staining for GluR2/3 and GluR4 revealed dense motor neurones in the ventral horn. These results suggest that in the rat spinal cord AMPA-type glutamate receptors vary in composition according to the region where they are expressed.

Turkish Journal of Veterinary & Animal Sciences

Infection with the parasite Diplostomum sp. can lead to severe ocular pathology and may result in host mortalities in commercial fish farming. Here we show that such infection is rife in a major lake used for fishing in Turkey. In a study of Acanthobrama marmid fish in Keban Dam Lake, Elazığ, Turkey, we found the infection period was normally between May and September each year, and that the prevalence and abundance of eye lens parasites reached a maximum in September. Typical results of metacercariae occurrence in the fish eye included exophthalmia, local haemorrhage and lens cataract. There was a significant …

Turkish Journal of Veterinary & Animal Sciences

Carbohydrate compositions of apolipoprotein E (apo E) isolated from rat serum very low density lipoproteins (VLDL) and intermediate density lipoproteins (IDL) + low density lipoproteins (LDL) were analyzed and compared. Rat serum VLDL and IDL+LDL were isolated by a discontinuous density gradient ultracentrifugation for 7.9x107g.min. Following delipidization, apolipoproteins were subjected to sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis. Apo E polypeptides were eluted by diffusion in 100 mM PBS buffer (pH 7) containing 0.05% SDS. Sugars were derivatized with 1-phenyl-3-methyl-5-pyrazolone (PMP) and subjected to high performance liquid chromatography (HPLC) analysis. N-acetylneuraminic acids of apo E were derivatized with 4,5-methylenedioxy-1,2-phenylene-diamine dihydrochloride …

Turkish Journal of Veterinary & Animal Sciences

The prevalence and colonization sites of Helicobacter spp. in the stomachs of dogs, and their association with gastric pathology were investigated. Scraping cytology, culture, urease test and histology were used to detect helicobacters in the stomachs of necropsied dogs. Gastric Helicobacter spp. were detected in 103 (84.4%) of 122 dogs from 1 month to 14 years of age. The uncultured spiral organisms seen in the most of stomachs were designated as H. heilmannii. Microscopical examination of stained mucosal scrapings was found to be superior for the diagnosis of gastric helicobacters. Six (4.9%) spiral organisms were isolated from 122 stomachs and …
