We investigated the relationships between tumor necrosis factor (TNF) gene polymorphism, circulating TNF-alpha (TNF-α) concentrations, and bone mineral density (BMD) in the lumbar spine. TNF gene polymorphisms studied were the Nco I polymorphism within the first intron of TNF-beta (TNF-β) and three single nucleotide polymorphisms in the promoter region of(More)
This study was performed to investigate whethere there is cross-reactivity between Dirofilaria immitis and three intestinal nematodes of dogs. In ELISA, D. immitis-infected dog sera obtained at the 4th molting stage (9-11 weeks) and microfilaremic stage (25-30 weeks) were shown to be highly reactive with crude extract of T. canis. In immunoblotting, some(More)
The aim of this study was to investigate the developmental rate, lipid and mitochondrial distribution and gene expression in oocyte-derived embryos selected on the basis of brilliant cresyl blue (BCB) staining. Lipid content and mitochondrial distribution in Day 8 blastocysts were evaluated by fluorescence intensity, while gene expression was analyzed by(More)
for behavioral hyperactivity of WKHAIWKY rats on rat Chr 8 near the Apeh (also called Acph) marker [2]. The as3 neuronal nicotinic acetylcholine receptor gene had been mapped close to the Apeh marker on mouse Chr 9 [4] and thus represented a good positional candidate for the hyperactivity QTL since these receptors are present on striatal nerve terminals(More)
A male deformed Korean native calf was examined macroscopically. The deformed calf had no caudal vertebral columns from 5th lumbar vertebra, sacrum and coccygeal vertebrae. The spinal cord was terminated in the vertebral foramen of the 3rd lumbar vertebra. The cervical vertebrae had scoliosis and the 3rd and 4th cervical vertebrae were fused. The 2nd and(More)
Interleukin-15 (IL-15) has been suggested to participate in bone metabolism by stimulating osteoclast differentiation and mediating inflammatory bone loss. This study investigated the effect of IL-15 gene polymorphisms on the bone mineral density (BMD) and bone fracture rates of postmenopausal women. Sequencing of the IL-15 gene in 24 Koreans revealed 16(More)
We identified a 3.4-kb 5′-flanking region of the rPL-I gene and examined its promoter activity using rat trophoblast Rcho-1 cells. A regulatory element between base pairs (bp) −2,487 and −2,310 in the 5′-flanking region was essential for maximum promoter activity of the rPL-I gene. This regulatory element was further characterized between bp −2,443 to(More)
This study was performed to compare acid-phosphatase staining with polymerase chain reaction (PCR) analysis for the diagnosis of Dirofilaria repens infection. The infection of D. repens was confirmed in Korean reared German shepherd dogs. Knott's tests were carried out for the detection of microfilaria in 543 Korean reared German shepherd dogs (255 females(More)
Oocyte quality is a key factor affecting success of in vitro embryo production in cattle. Improving the microenvironment of oocytes during in vitro maturation (IVM) can increase developmental rate and embryo quality. Therefore, the objective was to determine whether denuded oocytes (DO) affect embryo development and ultrastructure of the zona pellucida (ZP)(More)
It is unknown whether gene expression in cloned placenta during pre- and postimplantation is associated with early pregnancy failure in the cat. In this study, protein expression patterns were examined in early-stage (21-day-old) domestic cat placentas of fetuses derived from AI (CP; N = 4) and cloned embryo transfer (CEP; N = 2). Differentially expressed(More)
