  • The adrenergic receptor beta 2 (ADRB2) plays a role in various physiological responses of the muscle to exercise, such as contraction and relaxation. Given its important role in muscle function, we investigated the structure of the horse ADRB2 gene and its expression pattern after exercise to determine if it can serve as a putative biomarker for recovery. Evolutionary analyses using synonymous and non-synonymous mutation ratios, were compared with other species (human, chimpanzee, mouse, rat, cow, pig, chicken, dog, and cat), and revealed the occurrence of positive selection in the horse ADRB2 gene. In addition, expression analyses by quantitative polymerase chain reaction exhibited ubiquitous distribution of horse ADRB2 in various tissues including lung, skeletal muscle, kidney, thyroid, appendix, colon, spinal cord and heart, with the highest expression observed in the lung. The expression of ADRB2 in skeletal muscle was significantly up-regulated about four folds 30 minutes post-exercise compared to pre-exercise. The expression level of ADRB2 in leukocytes, which could be collected with convenience compared with other tissues in horse, increased until 60 min after exercise but decreased afterward until 120 min, suggesting the ADRB2 expression levels in leukocytes could be a useful biomarker to check the early recovery status of horse after exercise. In conclusion, we identified horse ADRB2 gene and analyzed expression profiles in various tissues. Additionally, analysis of ADBR2 gene expression in leukocytes could be a useful biomarker useful for evaluation of early recovery status after exercise in racing horses.

  • Growth of cities and an increase in population result in the development-oriented policy, urban streams to lose their natural characteristics and functions by channelization, parking lot construction, and so forth. The streams fall into urban drains, which is the current status of urban streams. Recently, the interest in the stream environment and the ecosystem has been increased, and the efforts have been made to improve the traditional maintenance program for small streams. These efforts lead to the application of the natural recovery systems. This study applied the 240-meter model reach along the Oncheon stream, which locates in Dongrae-gu, Busan city. to analyze the natural recovery system. The efficiency of each system has been analyzed and the future improvements for the systems are presented. The results show that the stream maintenance program should consider the ecological environment. thereby minimizing the environmental effects. When the changes are inevitable, the maintenance program should adopt the methods. which closely simulate the original environmental elements. or are more favorable to the ecosystem.

  • Inhibition of gap junction-mediated intercellular communication (GJIC) has been considered as an important factor in the tumor promotion phase of carcinogenesis. Recovery effects of natural products on gap junctional intercellular communication are measured by scrape-loading and dye transfer method using Lucifer yellow after administration of phorbol-12-myristate-13-acetate (PMA) on WBF344 cells. Among tested natural products, the hexane fraction and subfractions (F-01 and F-04) of Setaria italica were relatively effective for recovery of GJIC. The hexane fraction of Setaria italica $(EC_{25},\;12.14\;{\mu}g/ml)$ and subfractions $(F-01:EC_{50},\;10.74\;{\mu}g/ml;EC_{25},\;1.58\;{\mu}g/ml,\;F-04:EC_{50},\;11.03\;{\mu}g/ml;\;EC_{25},\;3.12\;{\mu}g/ml)$ revealed dose-dependent recovery effects on GJIC. Our data show GJIC activity measurement by Lucifer yellow spread on cells can be an effective tool for the screening of natural products with possible cancer chemopreventive effects.

  • Most damages of civil infrastructures under natural disasters are frequently occurred at surrounding areas of the river or the road. Every year, Recovery for these disaster damages are performed by the government. Recently, the government decide to change current recovery plan system because current recovery plan which doesn't consider future disaster impacts at a site has been proved to be ineffective. Accordingly, new permanency recovery plan system is needed and its corresponding ideas are presented in this research considering more detailed disaster damage classifications and cause assessments. The proposed permanency recovery plan would also provide more systematic and diverse recovery response strategies including both two concepts, for example Preparedness considered by risk assessment and management, and Mitigation investigated by hazard impact analyses.

  • This paper presents the applicability of natural zeolite (Clinoptilolite) for recovery of ammonium nitrogen from high-strength wastewater stream. Isotherm experiments showed the ammonium exchange Clinoptilolite followed Freundlich isotherm and its maximum exchange capacity was $18.13mg\;NH_4{^+}-N/g$ zeolite. The X-ray photoelectron spectroscopy (XPS) analysis indicated that a significant amount of nitrogen was adsorbed to the Clinoptilolite. Optimal flowrate for recovery of high concentration ammonium nitrogen was determined at 16 BV/d (=19.2 L/min) throughout the lab-scale column studies operated under various flowrate conditions. This study also provided a method to determine the recovery rate of final product of nitrogen fertilizer based on the model application to the lab-scale continuous data.

  • Purpose: The aim of our study was to evaluate natural recovery of neurologic injury after minor dental surgery based on subjective neurologic evaluation. Materials and Methods: From December 2005 through July 2009, 30 patients from Seoul National University Bundang Hospital were identified as having been treated with minor dental surgery. The patients were composed of 12 men and 18 women, with a mean age of 50.6 years. The median duration of this study was 62 weeks. Results: The patients were treated by implants (17 cases), tooth extractions (6 cases), bone grafts (4 cases), inferior alveolar nerve transpositions (2 cases) and periodontal surgery (1 case) prior to the occurrence of altered sensation. Areas of altered sensation after minor surgery included the lip (36.7%), chin (30.0%) and tooth (21.7%), and at final follow-up, there was no change of ranking. Altered sensations expressed by patients included numbness (33.3%), discomfort (22.9%), relieving sense (14.6%), tingling (14.6%) and itching (14.6%). There was no change of ranking of altered sensation at the last follow-up. Patients experienced the altered sensation always (47.8%), during tactile stimulation (26.1%), when chewing food (13.0%), and talking (13.0%). Mean visual analogue scale (VAS) was $3.43{\pm}2.84$ for pain and $6.64{\pm}2.72$ for paresthesia. VAS of pain was decreased significantly between the first visit and the end of follow-up, and paresthesia also showed a significant difference. Conclusion: Altered sensations may occur at any time after minor dental surgery, but we observed that natural recovery of altered sensation occurred as time went on.

  • The compressibility of fracture in naturally fractured reservoir is larger than the compressibility of matrix in rock, although the compressibility of a typical rock is very small. The effective compressibility including the fracture compressibility should be considered to predict oil recovery correctly. It is hard to quantify changes of fracture aperture and pore volume in reservoir without the effective compressibility. In this study, oil recovery is analyzed by commercial simulator concerning the fracture compressibility based on fracture properties. We found that the effective compressibility affects oil recovery with change of polymer flooding factors such as polymer molar weight, concentration and injection rate. The estimated cumulative oil production is smaller with the effective compressibility than without it. Also, bottomhole pressure decreases rapidly without considering effective fracture compressibility.

  • The anaesthetic effect of tricaine methanesulfonate (MS-222) concentrations and water temperatures for longtooth grouper (Epinephelus moara) and hybrid grouper (E. moara ♀ × E. lanceolatus ♂) were investigated. Anesthetic induction and recovery time were measured at 18, 22, 26 and 30℃ of Cwater temperature and 100, 150, 200 and 250 ppm of anesthetic concentrations. Anesthetic induction time tended to decrease with increasing concentration and water temperature. Recovery time was proportional to concentration, but inversely proportional to water temperature. However, there was no significant differences in recovery time at 22℃ or lower. The optimal anesthesia condition was 30℃ and 100 ppm, which was the shortest recovery time for longtooth grouper, and 150 ppm at 30℃ in the case of hybrid grouper because anesthetic time is significantly different with 100 ppm in spite of no significant differences with 100 ppm for recovery time. As a results of two-way ANOVA test, there was a significant difference between the species of longtooth and hybrid grouper. On the other hand, there was no interaction effect between concentration and species. Also, there was no interaction effect among species, concentration, and water temperature.
