Granulosa cells surround the oocyte within the ovarian follicle and play an essential role in creating conditions required for oocyte as well as follicular development. The current study was conducted to examine the gene expression profile of mouse ovaries during the primordial to primary follicle transition process. Total RNAs from mouse ovaries on day 5 and day 12 were synthesized cDNA using annealing control primers. The DEGs were cloned and their identities were analyzed by BLAST search. The Plekha5 and Anxa11 were highly expressed in primary follicle stage. By contrast, their expression was increased in granulosa cells at the primary follicle stage. We have successfully discovered a list of genes expressed in day 5 and day 12 ovaries and confirmed that some of them are differentially expressed in PMF and/or PRI. This is a spatial-temporal regulatory mechanism on the ovarian folliculogenesis through membrane fusion. The gene expression profile from the current study would provide insight for future study on the mechanism(s) involved in primordial-primary follicular transition. This will provide information for identification of the mechanism of ovarian dysfunction.

Information on the prevalence of S. aureus and the current antimicrobial resistance profile is necessary in selecting the appropriate treatment of S. aureus infections in any part of the world. This study examined the frequency and antibiotic resistance list of S. aureus isolates obtained from clinical specimens at one hospital in Korea. A total of 1,746 gram positive cocci collected were identified as S. aureus. S. aureus isolates were obtained from different samples including sputum (N=565; 32.4%), endotracheal aspirate (358; 20.5%), wounds (329; 18.8%), blood (137; 7.8%), urine (67; 3.8%), and pus (59; 3.4%). All 1,545 S. aureus (100%) strains screened from sputum (565; 36.6%), endotracheal aspirate (388; 25.1%), wounds (329; 21.3%), blood (137; 8.9%), urine (67; 4.3%), and pus (59; 3.8%) were sensitive to glycopeptide (vancomycin, teicoplanin), oxazolidinone (linezolid) and stretogramin (quinupristin/dalfopristin). The prevalence of resistant S. aureus was significantly (P＜0.01) lower in urine, blood, pus, wounds, and sputum than in endotracheal aspirates. As a result, there was a significant difference in the antibiotic resistance of S. aureus according to the clinical specimens.

The tendency of students to become adults in the future to improve the country's public health policy and to determine the socio-economic development of the research is very important. The objectives of this study were to examine the changes in body weight, body mass index (BMI), body composition, and complete blood cell count in a group of male and female university students. Among the body compositions, height, weight, BMI, muscle volume, basal metabolic rate, red blood cells, hemoglobin, and hematocrit showed a correlation between the amount shown both had statistical significance (p＜0.01). In particular, platelets showed a rather different result from fat and body fat percentage, and were positively correlated with waist-hip ratio points (p＜0.01). This study may be useful as it provides the basic data necessary for students of healthcare. Therefore, developing a sustainable management system of healthcare on a national level for university students is very important.
