Purpose: The purpose of this study was to investigate the relationship between teaching effectiveness and clinical practice satisfaction among nursing students. Method: The subjects of this study were 107 junior and senior nursing students in E university. Data were collected using self-reported questionnaire including general and practicum related characteristics, teaching effectiveness of clinical instructors and clinical practice satisfaction from September 12 to September 21, 2011. Collected data were analyzed by SPSS 19 program using t-test, ANOVA with Scheffe test, and Pearson`s correlation coefficients. Result: The mean score of teaching effectiveness was 3.35(±.51), and mean of clinical practice satisfaction was 3.19±.47. There were significant differences of teaching effectiveness of clinical instrutor by satisfaction of overall clinical practicum(F=8.332, p<.001), satisfaction of practice hour(F=3.230, p=.044), and satisfaction of major(F=9.883, p<.001). There were significant differences of clinical practice satisfaction by grade(t=2.274, p=.025), motive of choosing nursing science as a major(F=3.329, p=.007), satisfaction of overall clinical practicum(F=17.437, p<.001), satisfaction of practice hours(F=9.925, p<.001), and satisfaction of nursing major(F=12.748, p<.001). Relationship between teaching effectiveness of clinical instructor and clinical practice satisfaction showed positive correlation(r=.704, p<.001). Conclusion: In this study, teaching effectiveness of clinical instructor was related with clinical practice satisfaction. Therefore, we should consider improving teaching effectiveness of clinical instructor to improve clinical practice satisfaction.

Myeloid differentiation factor 88 (MyD88) is an intracellular adaptor protein involved in Toll signaling pathway. In this study, we monitored the response of 4 key genes of the insect immune system against Beauveria bassiana JEF-007 in Tenebrio molitor using RT-PCR. TmGPR, antimicrobial peptide Tenecin 1 and Tenecin 2 were up-regulated after fungal infection. To better understand the roles of Toll signaling pathway in mealworm immune system, TmGRP and TmMyD88 was knocked down by RNAi silencing. Target gene expressions were decreased at 2 days post-dsRNA injection, and dramatically reduced at 6 days post-dsRNA injection. Therefore, mealworms were compromised by B. bassiana JEF-007 at 6 days post-dsRNA injection. Silencing of the TmMyD88 and TmGRP resulted in reducing the resistance of the host to fungal infection. However, only dsTmMyD88 showed significant difference with dsEGFP by statistical analysis, which may be due to partial gene knock down of dsGRP. These results indicate that TmMyD88 is required in mealworms for survival against B. bassiana JEF-007.

Entomopathogenic fungi are facultative microorganisms, dwelling in soil or infecting host insects, and some of the genera have been used as biological control agents worldwide. Collection of fungal isolates should be a platform for the development of highly effective resources, thus in this work we constructed a fungal library using a mealworm pathogenecity-based fungal collection method and further characterized some isolates with high virulence. A phylogenetic three was generated, and of the isolates 17 isolates’ biological features were characterized, such as morphology, spectrum of virulence, cultural characteristics, thermo-stability of fungi, production of biologically active materials, such as enzymes. This work reports an attractive entomopathogenic fungal library including the information of effective isolates in pest management.

The effect of various levels of proteins, sulfates, and molecular weight (Mw) of a sulfated-glycoprotein (NF₃) from a sea cucumber, Stichopus japonicus, on nitric oxide (NO) releasing capacity from RAW 264.7 cells was investigated. The NF₃ derivatives had various amounts of proteins (4.8∼11.2%) and sulfates (6.8∼25.2%) as well as different Mw (640.3×10³∼109.2×10³ g/㏖). NF3 was able to stimulate RAW 264.7 cells to release NO with lower protein contents, indicating that the protein moiety was not an important factor to stimulate macrophages. On the other hand, the NO inducing capacity was significantly reduced with decreased levels of sulfates and Mw, implying that sulfates and Mw played a pivotal role in activating RAW 264.7 cells. It was not clear why sulfates and a certain range of Mw were essential for stimulating macrophages. It appeared that certain levels of sulfates and Mw of sulfated-glycoproteins were required to bind to the surface receptors on RAW 264.7 cells.

To examine the differential protein expression pattern in the 11.5 day post-coitus (dpc) and 18.5 dpc placenta of mouse, we have used the global proteomics approach by 2-D gel electrophoresis (2-DE) and MALDI-TOF-MS. The differential protein patterns of 3 placentae at the 11.5 dpc and 18.5 dpc from nature mating mice were analyzed. Proteins within isoelectric point range of 3.0~10.0, separately were analyzed in 2DE with 3 replications of each sample. A total of approximately 1,600 spots were detected in placental 2-D gel stained with Coomassie-blue. In the comparison of 11.5 dpc and 18.5 dpc placentae, a total of 108 spots were identified as differentially expressed proteins, of which 51 spots were up-regulated proteins such as alpha-fetoprotein, mKIAA0635 protein and transferrin, annexin A5, while 48 spots were down-regulated proteins such as Pre-B-cell colony-enhancing factor 1(PBEF), aldolase 1, A isoform, while 4 spots were 11.5 dpc specific proteins such as chaperonin and Acidic ribosomal phosphoprotein P0, while 3 spots were 18.5 dpc specific proteins such as aldo-keto reductase family 1, member B7 and CAST1/ERC2 splicing variant-1. Most identified proteins in this analysis appeared to be related with catabolism, cell growth, metabolism and regulation. Our results revealed composite profiles of key proteins involved in mouse placenta during pregnancy.
