Ticks are vectors that cause disease by transmitting bacteria, viruses, and protozoa to humans or animals. The Asian longhorned tick Haemaphysalis longicornis, a vector of medical and veterinary importance, is widely distributed in the Korean peninsula and can transmit various pathogens including Rickettsia spp., Borrelia spp., Francisella spp., Coxiella spp., and severe fever with thrombocytopenia syndrome virus (SFTS virus). Despite the abundance and importance, studies on the microbiome of H. longicornis in Korea are limiting. Here we first report the microbiome diversity of H. longicornis in terms of region, stage, and sex. H. longicornis used in this study were collected from 16 different regions. The V3‐V4 region was amplified and sequenced by MiSeq platform. The microbial diversity analysis was performed using Qiime2. A total of 1,754,418 non‐chimeric reads were obtained from a total of 46 samples, and an average of 126 operational taxonomic units (OTUs) and a total of 1,398 OTUs were identified. Our results were used for H. longicornis microbial community database construction for each region that enables to identify singularities in each region. [ABSTRACT FROM AUTHOR]

In 1993, after 10 years of absence, malaria re-emerged in the Republic of Korea in Gyeonggi and Gangwon Provinces near the Demilitarized Zone (DMZ). Anopheline mosquitoes are known to play a critical role in malaria transmission. Several studies have used gene expression data to examine the transcription responses of Anopheles gambiae after microbial and Plasmodium infections; however, as of now, there have been no reports of studies concerning the innate immune response and apoptosis in Anopheles sinensis. We have constructed two independent cDNA libraries from An. sinensis challenged with actinomycin-D (T, treated with apoptosis-inducing chemical) and without actinomycin-D (C, control). Analysis of the 5704 (C, 2848; T, 2856) expression sequence tags (ESTs) generated from these libraries identified 884 contigs (C, 421; T, 463) and 2180 singletons (C, 1038; T, 1142) with average lengths of 831 and 817 bp, respectively. Furthermore, comparison of our EST sequences against the eukaryotic orthologous group database showed that 4324 (75.82%) of 5704 sequences could be grouped into three major functional categories. These EST data provide the basis for further studies characterizing the molecular mechanisms of midgut apoptosis. [ABSTRACT FROM AUTHOR]

14-3-3 proteins are known to play a pivotal role in cell survival, apoptosis and signal transduction. The 14-3-3ζ isoform has been cloned and characterized from many eukaryotic organisms, including the fruit fly and silkworm. However, no study on mosquito 14-3-3 has been reported to date. In an attempt to investigate the function of 14-3-3 in midgut epithelial cells undergoing apoptosis, a cDNA library was generated from the malaria vector, Anopheles sinensis, which was treated with apoptosis-inducing Actinomycin-D. We were able to identify and obtain A. sinensis 14-3-3ζ cDNA ( Ansi14-3-3ζ) from expressed sequence tags (EST) analysis after conducting massive sequencing of the A. sinensis cDNA library. Ansi14-3-3ζ has very high homology to 14-3-3 homologs of various insects, such as Anopheles gambiae (100%), Aedes aegypti (100%), Drosophila melanogaster (96%), Bombyx mori (93%), Apis mellifera (93%) and Mus musculus (81%), indicating that mosquito 14-3-3ζ is a highly conserved gene in diverse organisms. Analysis of temporal expression patterns showed that Ansi14-3-3ζ mRNA is highly expressed in egg, early pupae and adult stages and is also expressed, although at low levels, in fourth instar larvae and late pupae. In response to two immune elicitors (lipopolysaccharide and laminarin), no striking induction of 14-3-3ζ mRNA was observed in A. sinensis. Further studies of the precise biological function, inducibility and subcellular distribution of 14-3-3ζ are required in Plasmodium invasion-induced apoptotic midgut cells in A. sinensis in the context of the Time Bomb model.

This study investigated the clinical application of the 2006 Third Revised Korean Nurses' Code of Ethics and the moral sensitivity of nurses. A total of 303 clinical nurses in South Korea participated in the survey in May and June 2011. As instruments of this study, we used the 15 statements of the Korean Nurses' Code of Ethics and Korean Moral Sensitivity Questionnaire. The mean score for application was 3.77 ± 0.59 (out of 5), and the mean score for moral sensitivity was 5.14 ± 0.55 (out of 7). The correlation coefficient (r) of the application and moral sensitivity was 0.336 (p < 0.001). Nurses who scored high on moral sensitivity also scored high on application (t = -5.018, p < 0.001). In clinical settings, educational programmes to develop the moral sensitivity of nurses are necessary for improving the application of the code of ethics.

Hepatopancreatic parvovirus (HPV) of shrimp is distributed worldwide and the entire genome of Thailand and Indian strains (PmDNV) and one Australian strain (PmergDNV) have now been reported. The complete nucleotide sequence of a HPV strain isolated from the fleshy prawn Fenneropenaeus chinensis in Korea (FcDNV) was determined and compared to previously reported sequences. The entire genome of FcDNV contains 6,336 nucleotides, with 40% G+C content, which is the biggest of the known HPV strains. The HPV genome has three open reading frames (ORFs) with a slight overlap between the first and second ORFs. The three ORFs encode the NS2 and NS1 proteins and VP that consist of 425, 578, and 820 amino acids, respectively. Among the three proteins, the NS1 protein shows the highest sequence similarity to the NS1 protein of other known HPV strains, followed by the NS2 protein and the VP protein. Phylogenetic analyses showed that HPV can be grouped into three genotypes, as previously reported, and FcDNV can be grouped as genotype I, with HPV strains isolated in Madagascar and Tanzania. The nucleotide sequences of the noncoding regions at the 5'- and 3'-ends of the plus-strand genome showed a Y-shaped hairpin structure and simple hairpin structure, respectively.

Aims: The purpose of this study was to identify the incidence rate of eye disorders and further to identify factors related to incidence of eye disorders in intensive care unit patients., Background: Although the incidence of eye disorders in intensive care unit patients is very high, it is difficult to come to an accurate estimate of number of eye disorders in intensive care unit patients because eye disorders are often perceived to be minor problems., Design: A retrospective, descriptive survey design was used., Method: The medical records of a total 235 patients with eye disorders were identified through a review of the medical records of 2,500 patients hospitalised in the intensive care units of Yonsei University Hospital, Seoul, Korea from January to December, 2004. To examine factors related to eye disorders, 522 patients without eye disorders from the cohort of 2,265 patients were randomly selected. Factors related to incidence of eye disorder were included in a multiple logistic regression model, after screening by the chi-squared test., Results: The incidence rate for eye disorders in the intensive care unit patients was 8.6%. From the multiple regression model, the following odds ratios (95% confidence intervals) of eye disorder were estimated; length of stay in intensive care unit of at least seven days: 2.8 (1.70-4.70); death: 2.5 (1.47-4.29); drowsy mental state: 2.2 (1.10-4.37); stupor mental state: 7.0 (3.20-15.45); coma mental state: 10.8 (3.47-33.74); no self-respiration: 1.9 (1.00-3.52); positive end expiratory pressure: 2.9 (1.66-4.92); sedatives: 4.2 (2.26-7.74); muscle relaxants: 2.3 (1.11-4.95)., Conclusions: Factors related to incidence of eye disorders in intensive care unit patients identified in this study support the need to pay attention to eye problems and eye care in intensive care unit patients., Relevance to Clinical Practice: An evidence-based eye care protocol should be provided as routine care to prevent eye complication, especially in critically ill patients with mechanical ventilators, positive end expiratory pressure, sedatives or muscle relaxants and for patients whose mental status is decreased.

As one of four major causes of death in Korea, diabetes mellitus has dramatically increased since the 1980s because of westernized lifestyles. Diabetes patients try to learn the knowledge and skills necessary for disease care since diabetes management is highly dependent on self- management. To do this, patients pursue more health information and proper sources for themselves. This study developed an evaluation tool including categories with items necessary for evaluation of Websites for health information on diabetes mellitus, as a method to offer consumers certified high quality health information on diabetes.
