Objective: The aim of the current study is to investigate the relationship between prohibitin (PHB), capping actin protein of muscle Z-line beta subunit (CAPZB), and tektin-2 (TEKT2) and sperm motility in Murrah buffalo. Methods: We collected the high-motility and low-motility semen samples, testis, ovary, muscle, kidney, liver, brain and pituitary from Murrah buffalo, and analysed the expression of PHB, CAPZB, and TEKT2 in mRNA (message RNA) and protein level. Results: Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) result showed that the expression of PHB was higher and CAPZB, TEKT2 were specifically expressed in testis as compared to the other 6 tissues, and that in testis, the expression of TEKT2 was higher than that of CAPZB and PHB. Immunohistochemistry test revealed that all three genes were located on the convoluted seminiferous tubule and enriched in spermatogenic cells. Both qRT-PCR and Western Blot results showed that the expression levels of PHB, CAPZB, and TEKT2 were significantly lower in the low-motility semen group compared to the high-motility semen group (p<0.05). Conclusion: The expression levels of PHB, CAPZB, and TEKT2 in Murrah buffalo sperm have a high positive correlation with sperm motility. And the three genes may be potential molecular markers for the decline of buffalo sperm motility.

The delivery of high-quality antenatal care is a perennial global concern for improving maternal and neonatal outcomes. Antenatal care is currently provided mainly on a one-to-one basis, but growing evidence has emerged to support the effectiveness of group antenatal care. Providing care in a small group gives expectant mothers the opportunity to have discussions with their peers about certain issues and concerns that are unique to them and to form a support system that will improve the quality and utilization of antenatal care services. The aim of this article is to promote group antenatal care as a means to increase utilization of healthcare.

This study reviewed published studies on interventions used by hospitals, health insurance programs, or governments to improve use of medicines in foreign countries. Interventions to improve use of medicines are classified into two categories: 1) information strategies-dissemination of educational materials, group education, one-to-one educational outreach, drug utilization review, and feedback; 2) managerial strategies- formularies, prior authorization, and financial incentives. Dissemination of educational materials, which is a common intervention, was unsuccessful in changing physicians' prescribing behaviors. Problem-based small group education was more likely to change behaviors than didactic large group education. One-to-one educational outreach(academic detailing) was among the most effective strategies used to change prescribing behaviors. Prospective drug utilization review (DUR) program was more successful in improving use of medicines than retrospective DUR program. Feedback intervention has been reported to be ineffective to change behaviors. Formularies are frequently used to control medication use by most health insurance programs. Financial incentives provide physicians economic incentives according to appropriateness of prescribing. However, few published studies have assessed the efficacy of formularies or financial incentives. Prior authorization requires physicians to get authorization from health insurers before prescribing a certain group of drugs which is usually of high costs or risk. There is no magic bullet for quality use of medicines. Multifaceted interventions that help to predispose, enable, and reinforce desired behaviors are more likely to be successful.

Objectives: The suicide rate in Korea is increasing every year, and is the highest among the Organization for Economic Cooperation and Development countries. Psychiatric patients in particular have a higher risk of suicide than other patients. This study was performed to evaluate determinants of mental health care utilization among individuals at high risk for suicide. Methods: Korea Health Panel data from 2009 to 2011 were used. Subjects were individuals at high risk of suicide who had suicidal ideation, a past history of psychiatric illness, or had utilized outpatient services for a psychiatric disorder associated with suicidal ideation within the past year. The chi-square test and hierarchical logistic regression were used to identify significant determinants of mental health care utilization. Results: The total number of subjects with complete data on the variables in our model was 989. Individuals suffering from three or more chronic diseases used mental health care more frequently. Mental health care utilization was higher in subjects who had middle or high levels of educational attainment, were receiving Medical Aid, or had a large family size. Conclusions: It is important to control risk factors in high-risk groups as part of suicide prevention strategies. The clinical approach, which includes community-based intervention, entails the management of reduction of suicidal risk. Our study identified demographic characteristics that have a significant impact on mental health care utilization and should be considered in the development of suicide prevention strategies. Further studies should examine the effect of mental health care utilization on reducing suicidal ideation.

This experiment was conducted to investigate the variation of nitrogen use efficiency, nitrogen uptake efficiency, physiological utilization efficiency and their relationships with growth characteristics in the 28 Korean rice cultivars. Nitrogen use efficiency of 28 rice cultivars was 47.74, nitrogen uptake efficiency was 0.71, and physiological utilization efficiency was 68.76 in average. Nitrogen use efficiency of rice cultivars had low variation ranged from 44.09 to 51.91, but nitrogen uptake efficiency were relatively high variation from 0.51 to 0.90, and physiological utilization efficiency was from 51.71 to 94.26. The high efficient group in nitrogen uptake efficiency whose value was calculated above 0.80 included Daeanbyeo, Seojinbyeo, Ansungbyeo, Dongjinbyeo, and Hwaanbyeo, while the low efficient group with below 0.60 was Kwanganbyeo, Sampyeongbyeo, Soorabyeo, and Hwasungbyeo. Hwasungbyeo, Sampyeongbyeo, Soorabyeo for physiological utilization efficiency were more efficient cultivars, while Daeanbyeo, Seojinbyeo, Ansungbyeo were less efficient cultivars. Nitrogen uptake efficiency had positive correlation coefficients between dry matter weight of plant ($0.842^{**}$), leaf area index ($0.761^{**}$), and leaf nitrogen content ($0.599^{**}$), respectively. Therefore, the dry matter weight of rice plant and leaf area index was important characters to evaluate nitrogen uptake efficiency in rice cultivars. Also, more efficient cultivar in nitrogen uptake had higher chlorophyll meter value, which was appeared dark green color.

The purpose of this study was to investigate the effect of iron and selenium intakes on utilization of manganese in rats fed adequate, 2-fold, 4-fold iron and adequate, high selenium for 6 weeks. There was no difference feed intake across iron and selenium containing diet groups. Body weight gain in 2-fold iron and high selenium group(MFeHSe) was significantly higher than those in other groups. Serum iron level was increased with iron increment, and liver iron content was decreased with selenium supplementation. Selenium and manganese contents in tissues were decreased with iron increment. In the case of manganese balance, manganese excretion through feces was significantly increased as iron intake was increased. However, retention and apparent absorption of manganese were not significantly affected by dietary iron. From these results, it could be suggested that the supplementations of iron and selenium affected the manganese utilization. Therefore, it must be considered interaction with various minerals in micro-nutrient supplementations.
