This study was performed to investigate the serum creative kinase(CK) activity and CK isoenzyme in Jindo dog. Serum CK activity and CK-isoenzyme were analyzed in 53 Jindo dogs of both sexes. The mean value and normal range of serum CK activity were 24.1 lu/$\ell$ and 7-91 lu/$\ell$, respectively, in 29 female dogs, 24.8 lu/$\ell$ and 8-89 lu/$\ell$ in 24 male dogs. The CK activity of the Puppy showed a tendency to be higher than that of the adult. There was no significance between Puppy and adult. Three isoenzymes (CK-MM, CK- BB, and CK-MB) were recognized in serum. The mean percentages of female and male were as follows: 48.31fp and 48.1% for CK-MM, 35.49) and 33.61fp for CK-BB, and 8.2% and 10.1% for CK-MB in the puppy and 46.21% and 46.1 % for CK-MM, 36.3% and 37.6% for CK-BB and 10.5% and 9.5% for CK-MB in the adult.

A bench-scale feasibility study was conducted with solid farming feed to evaluate a treatment process for microbiological removal of nitrogen (N) and phosphorus (P). Strains, Bacillus sp. CK-10 and Bacillus sp. CK-13, were originally isolated from water samples of shrimp farming pond. Simultaneous removal of N/P in marine media was monitored in the co-cultures, CK-10 and CK-13. As the results, $400\;{\mu}M\;NH^{+}_4$ and $400\;{\mu}M\;NO^{-}_2$ were eliminated within 12 hours and $NO^{-}_3$ within 36 hours, and $500\;{\mu}M\;PO^{-3}_4$ was completely disappeared within 36 hours from the media. Cultures of CK-10 and CK-13 were applied for removal of N/P leached from shrimp farming fred. HPAEC-PAD system was used to analyze sugars in farming feed, resulting in resolution of various sugars including glucose, galactose, galatosamine, mannose, and fucose. $0.2\%$ (w/v) Pulp densities of the farming feed contained approximately $33.3\;{\mu}M\;NH^{+}_4,\;12.9\;{\mu}M\;NO^{-}_2.\;81.5\;{\mu}M\;NO^{-}_3\;and\;248\;{\mu}M\;PO^{-3}_4$ which could dissolved within 72 hours of leaching in aqueous solution followed by bacterial removal. Complete bacterial removal of N/P was achieved within 84 hours at $0.2\%$ of the feed in co-cultures, whereas single cultures removed to incompletion of N/P during the incubation period. This work demonstrated that test cultures, CK-10 and CK-13 showed effective removal of N/P derived from shrimp farming feed.

Kimchi is well Down for its taste and health function. However, recently Kimchi consumption has been falling because of its salty taste, spice flavor and pungency. This study was aimed to prepare a less salty and more mildly flavored Kimchi with the addition of tomato which contains a red color similar to that of the hot pepper used in traditional kimchi preparation has functionality. The pH, total acidity, color, texture, microbes, sugar, salt, Na and K content of the tomato kimchi were measured. The total amount of phenolic compounds of the tomato kimchi was five times higher than that of traditional kimchi without tomato. A sensory evaluation of the tomato kimchi demonstrated its higher acceptability in overall color, fresh flavor and hot taste but no difference in acidity compared to the traditional kimchi.

Background: For the determination of creatine kinase (CK)-MB, the immunoinhibition method is utilized most commonly. However, the estimated CK-MB activity may be influenced by the presence of CK isoenzymes in some conditions like cancer. Thus, a CK-MB-to-total-CK ratio more than 1.0 could be found in such a situation. The study aimed to explore the relationship of cancer to high CK-MB-to-total-CK ratio. Materials and Methods: From January 2011 to December 2014, laboratory data on all CK-MB and total CK test requests were extracted at Far Eastern Memorial Hospital (88,415 requests). Patients with a CK-MB-to-total-CK ratio more than 1.0 were registered in this study. Clinical data including tumor location, tumor TNM stage and metastatic status were also collected. Results: A total of 846 patients were identified with a CK-MB-to-total-CK ratio more than 1.0. Of these, 339 (40.1%) were diagnosed with malignancies. The mean CK-MB-to-total-CK ratio was significantly higher in malignancy than in non-malignancy ($1.35{\pm}0.28$ vs $1.25{\pm}0.23$, p<0.001) groups. The most frequent malignancy with a CK-MB-to-total-CK ratio more than 1.0 was colorectal cancer ($1.42{\pm}0.28$, 16.5%, n=56), followed by lung cancer ($1.38{\pm}0.24$, 15.9%, n=54) and hepatocellular carcinoma (14.5%, n=49). Higher CK-MB-to-total-CK ratios in hematological malignancies ($1.44{\pm}0.41$)were also noted. Additionally, the CK-MB-to-total-CK ratio was markedly higher in advanced stage malignancy than in early stage ($1.37{\pm}0.26$ vs. $1.29{\pm}0.31$, p=0.014) and significantly higher in liver metastasis than in non-liver metastasis ($1.48{\pm}0.30$ vs. $1.30{\pm}0.21$, p<0.001). Conclusions: The CK-MB-to-total-CK ratio is an easily available indicator and could be clinically utilized as a primary screening tool for cancer. Higher ratio of CK-MB-to-total-CK was specifically associated with certain malignancies, like colorectal cancer, lung cancer and hepatocellular carcinoma, as well as some cancer-associated status factors such as advanced stage and liver metastasis.

The feasibility of using bacterial cultures with the ultimate aim for the marine environmental clean-up was explored. The present study reports on the bacterial elimination of nitrogens and phosphorus by strains CK-10 and CK-13 isolated from shrimp farming pond. The strains were identified as genus Bacillus on the basis of BIOLOG test, and designated as Bacillus sp. CK-10 and Bacillus sp. CK-13, respectively. Removal of nitrogens $(NH_4^+,\;NO_2^-,\;or\;NO_3^-)$ or phosphorus $(PO_4^{-3})$ as single N or P source was studied with single cultures under aerobic conditions. Complete elimination of all nitrogens in the concentration range of $100-400{\mu}M$ was achieved in single cultures as well as co-cultures within the given incubation period. Similar results were obtained from the test cultures containing $125-599{\mu}M\;PO_4^{3-}$. Simultaneous removal of all N/P was monitored in the co-cultures. As the results, $400{\mu}M\;NH_4^+\;and\;NO_2^-$ were eliminated within 12hrs and $400{\mu}M\;NO_3^-\;and\;500{\mu}M\;PO_4^{-3}$ were completely disappeared within 36 hrs from the media. The work demonstrated that co-cultures improved the concurrent removal of N/P from the media.

A simple and sensitive hydrogel-based detecting gel has been presented for the qualitative determination of cyanogen chloride(CK) using Konig reaction. To optimize Konig reaction conditions, the effects of pyridine and barbituric acid concentration were investigated. Under the optimized conditions, CK gas concentration was directly related with absorbance change at 567 nm. Based on aqueous solution test results, we finally prepared CK detecting hydrogel by absorbing pyridine and barbituric acid solution. Color change of the prepared CK detecting hydrogel was clearly observed when the detecting gel was exposed to 10 ppm CK gas.

The protein kinase $CK2{\alpha}$ (formerly Casein Kinase II) is implicated in tumorigenesis and transformation. However, the mechanisms of $CK2{\alpha}$ activation in breast cancer have yet to be elucidated. This study investigated the mechanisms of $CK2{\alpha}$ activation in estrogen signaling. Estrogen increased reactive oxygen species (ROS) production, $CK2{\alpha}$ activity, and protein expression in estrogen receptor positive ($ER^+$) MCF-7 human breast cancer cells, which were inhibited by the antioxidant N-acetyl-L-cysteine. $H_2O_2$ enhanced $CK2{\alpha}$ activity and protein expression. Human epidermal growth factor (EGF) increased ROS production, $CK2{\alpha}$ activity and protein expression in EGF receptor 2 (HER2)-overexpressing MCF-7 (MCF-7 HER2) cells, but not in MCF-7 cells. Estrogen induced the phosphorylation of p38 mitogen-activated protein kinase (MAPK). The p38 inhibitor, SB202190, blocked estrogen-induced increases in ROS production, $CK2{\alpha}$ activity and $CK2{\alpha}$ protein expression. The data suggest that ROS/p38 MAPK is the key inducer of $CK2{\alpha}$ activation in response to estrogen or EGF.

Objectives: Odontogenic keratocysts (OKCs) have a tendency to recur and possess an aggressive nature. the aim of the present study was to evaluate cytokeratin (CK) expression patterns as a method for the differentiation between dentigerous cysts (DCs) and OKCs, as their histomorphologic appearance are often indistinguishable. Materials and Methods: Formalin-fixed, paraffin-embedded tissue sections of 43 OKCs and 38 DCs were immunohistochemically analyzed with i-solution in a quantitative manner in order to evaluate the immunoreactivity of CK 10, 16 and 17. Results: CK 10 expression was evident in 79.1% of OKCs but found in only 18.4% of DCs (P<0.05), and CK 10 expression was observed to occur more frequently in OKCs (mean 25.45%) than in DCs (2.19%) (P<0.05). The expression of CK 16 was evident in 79.1% of OKCs but found in only 7.9% of the DCs (P<0.05) and CK 16 expression was observed to occur more frequently in OKCs (mean 4.33%) than in the DCs (0.61%) (P<0.05). The expression of CK 17 was evident in 88.4% of OKCs but seen in only 15.7% of the DCs (P<0.05) and CK 17 expression was observed to occur more frequently in OKCs (mean 31.11%) than in the DCs (2.37%) (P<0.05). Conclusion: The immunohistochemical detection of CK 10, 16 and 17 can be utilized as a valuable biomarker for use in distinguishing between OKCs and DCs, which have clinically significant differential diagnoses.

Protein kinase casein kinase 2 (CK2) is important in the regulation of cell proliferation and death, even under pathological conditions. Previously, we reported that CK2 regulates the expression of heme oxygenase-1 (HO-1) in stress-induced chondrocytes. In the present study, it was shown that CK2 is involved in the dedifferentiation and cellular senescence of chondrocytes. Treatment of primary articular chondrocytes with CK2 inhibitors, 4,5,6,7-terabromo-2-azabenzimidazole (TBB) or 5,6-dichlorobenzimidazole 1-β-D-ribofuranoside (DRB), induced an increase in senescence-associated β-galactosidase (SA-β-gal) staining. In addition, TBB reduced the expression of type II collagen and stimulated the accumulation of β-catenin, phenotypic markers of chondrocyte differentiation and dedifferentiation, respectively. It was also observed that the abrogation of CK2 activity by CK2 small interfering RNA induced phenotypes of chondrocyte senescence. The association between HO-1 and cellular senescence was also examined in CK2 inhibitor-treated chondrocytes. Pretreatment with 3-morpholinosydnonimine hydrochloride, an inducer of the HO-1 expression, or overexpression of the HO-1 gene significantly delayed chondrocyte senescence. These results show that CK2 is associated with chondrocyte differentiation and cellular senescence and that this is due to regulation of the expression of HO-1. Furthermore, the findings suggest that CK2 is crucial as an anti-aging factor during chondrocyte senescence.
