Human stem cells have been isolated from embryos as well as diverse somatic tissues. Much efforts have been made to apply those stem cells for therapeutic purpose. Molecular dissection of "stemness" and differentiation process will provide us a clue to further understanding of stem cell biology. The fate of stem cell is determined in part by internal regulation mediated by transcriptional control. A set of genes related to specific functions might be expressed and suppressed upon external or internal signaling. Therefore, it is necessary to identify the complete gene expression profile that defines the stem cell. Moreover, we should verify the potential of therapeutic stem cells regarding differentiation, specific function, tumorigenecity, and toxicity rigorously before the clinical application. At present we have only limited information on "stemness" and differentiation into specific lineages. In the genome era, we can draw a molecular portrait on these functional and morphologic changes along the differentiation, trans-differentiation as well as de-differentiation using the DNA chip technology. We need to accumulate database for gene expression at various steps of stem cell differentiation, which will enhance our knowledge for research on and medical application of stem cell.

BACKGROUND: Fever is a very common complication that has been related to poor outcomes after aneurysmal subarachnoid hemorrhage (aSAH). The incidence of acalculous cholecystitis is reportedly 0.5%–5% in critically ill patients, and cerebrovascular disease is a risk factor for acute cholecystitis (AC). However, abdominal evaluations are not typically performed for febrile patients who have recently undergone aSAH surgeries. In this study, we discuss our experiences with febrile aSAH patients who were eventually diagnosed with AC. METHODS: We retrospectively reviewed 192 consecutive patients who underwent aSAH from January 2009 to December 2012. We evaluated their characteristics, vital signs, laboratory findings, radiologic images, and pathological data from hospitalization. We defined fever as a body temperature of >38.3℃, according to the Society of Critical Care Medicine guidelines. We categorized the causes of fever and compared them between patients with and without AC. RESULTS: Of the 192 enrolled patients, two had a history of cholecystectomy, and eight (4.2%) were eventually diagnosed with AC. Among them, six patients had undergone laparoscopic cholecystectomy. In their pathological findings, two patients showed findings consistent with coexistent chronic cholecystitis, and two showed necrotic changes to the gall bladder. Patients with AC tended to have higher white blood cell counts, aspartame aminotransferase levels, and C-reactive protein levels than patients with fevers from other causes. Predictors of AC in the aSAH group were diabetes mellitus (odds ratio [OR], 8.758; P = 0.033) and the initial consecutive fasting time (OR, 1.325; P = 0.024). CONCLUSIONS: AC may cause fever in patients with aSAH. When patients with aSAH have a fever, diabetes mellitus and a long fasting time, AC should be suspected. A high degree of suspicion and a thorough abdominal examination of febrile aSAH patients allow for prompt diagnosis and treatment of this condition. Additionally, physicians should attempt to decrease the fasting time in aSAH patients.

6.Influence of Nursing Organizational Culture on Empowerment as Perceived by New Nurses.
Journal of Korean Academy of Nursing Administration 2011;17(1):88-95
PURPOSE: This study was done to identify the effect of nursing organizational culture on empowerment as perceived by new clinical nurses. METHODS: For the objective a sample of 175 new nurses from secondary/tertiary hospitals having not less than 250 beds located in B city was selected to complete a questionnaire. The collected data were analyzed using descriptive statistics, t-test, One-way ANOVA, Scheffe's test, Pearson correlation coefficients and simultaneous multiple regression with the SPSS 14.0 software program. RESULTS: As for nursing organizational culture as perceived by the respondent, relation-oriented culture had the highest average score (3.60+/-.63) out of a possible 5 points followed by hierarch-oriented culture, innovation-oriented culture and task-oriented culture with 3.45+/-.30, 3.19+/-.53 and 3.05+/-.46, respectively. The respondents' level of perceived empowerment was 3.06+/-.41. The factors influencing empowerment according to nursing organizational culture were innovation-oriented and relation-oriented culture in that order. These 2 variables were statistically significant predictors and explained 48.6% of the variance in empowerment. CONCLUSIONS: The results of this study indicate that emphasis should be given to nursing organizational culture strengthened by innovationoriented and relation-oriented culture, rather than task-oriented and hierarch-oriented culture, in order to foster harmonious empowerment among nurses at all levels.
