Genome shotgun sequencing and development of microsatellite markers for gerbera (Gerbera hybrida H.) by 454 GS-FLX

The objective of this research was to develop and characterize microsatellite markers for gerbera. We used shotgun sequencing with Roche 454 GS-FLX Titanium technology to identify microsatellite loci in gerbera genomic DNA (Gerbera hybrida). The total length of non-redundant sequences obtained was 22,527,019 bp, which consisted of 3,085 contigs and 28,249 singletons. We assembled 61,958 reads into 3,085 contigs, of which 114 (3.70%) contained microsatellite repeats. The average G+C content was 39.3%. Functional annotation to known sequences yielded 14.7% unigenes in the ‘Raon’ cultivar. Analysis of the gerbera genome DNA (‘Raon’) general library showed that sequences of (AT), (AG), (AAG) and (AAT) repeats appeared most often, whereas (AC), (AAC) and (ACC) were the least frequent. Primer pairs were designed for 80 loci. Only eight primer pairs produced reproducible polymorphic bands in the 28 gerbera accessions analyzed. A total of 30 alleles were identified from the eight polymorphic SSR loci, with two to eight alleles per locus (average level of 3.75). These markers will be useful for investigating genetic diversity and differentiation in gerbera. Keywords: Genetic diversity, genomics, microsatellite isolation, pyrosequencing, SSRs.

Laparoscopic Enucleation of a Nonfunctioning Neuroendocrine Tumor of the Pancreas

Laparoscopic approaches are increasingly used in pancreatic surgery. In the treatment of neuroendocrine tumors (NETs) of the pancreas, enucleation is one of the recommended surgery. Although many clinical experiences have reported the safety and efficacy of laparoscopic enucleation of functioning NETs, such as insulinomas, few reports have explored such treatment for non-functioning NETs. Here, we present a case of 70-year old female patient who underwent successful laparoscopic enucleation of a nonfunctioning NET located in the body of the pancreas

Pilot KaVA monitoring on the M87 jet: confirming the inner jet structure and superluminal motions at sub-pc scales

We report the initial results of our high-cadence monitoring program on the radio jet in the active galaxy M87, obtained by the KVN and VERA Array (KaVA) at 22 GHz. This is a pilot study that preceded a larger KaVA-M87 monitoring program, which is currently ongoing. The pilot monitoring was mostly performed every two to three weeks from December 2013 to June 2014, at a recording rate of 1 Gbps, obtaining the data for a total of 10 epochs. We successfully obtained a sequence of good quality radio maps that revealed the rich structure of this jet from <~1 mas to 20 mas, corresponding to physical scales (projected) of ~0.1-2 pc (or ~140-2800 Schwarzschild radii). We detected superluminal motions at these scales, together with a trend of gradual acceleration. The first evidence for such fast motions and acceleration near the jet base were obtained from recent VLBA studies at 43 GHz, and the fact that very similar kinematics are seen at a different frequency and time with a different instrument suggests these properties are fundamental characteristics of this jet. This pilot program demonstrates that KaVA is a powerful VLBI array for studying the detailed structural evolution of the M87 jet and also other relativistic jets.Comment: 10 pages, 9 figures, accepted for publication in PAS

Hepatic Splenosis Preoperatively Diagnosed as Hepatocellular Carcinoma in a Patient with Chronic Hepatitis B: A Case Report

We report on a case of hepatic splenosis. A 32-yr-old man underwent a splenectomy due to trauma at the age of 6. He had been diagnosed as being a chronic hepatitis B-virus carrier 16 yr prior to the surgery. The dynamic computer tomography (CT) performed due to elevated serum alpha-fetoprotein (128 ng/mL) demonstrated two hepatic nodules, which were located near the liver capsule. A nodule in Segment IVa had a slight enhancement during both the arterial and portal phases, and another nodule in Segment VI showed a slight enhancement only in the portal phases. Dynamic magnetic resonance imaging (MRI) of the mass in Segment VI showed enhanced development in the arterial phases and slight hyperintensivity to the liver parenchyma in the portal phases. These imaging findings suggested a hypervascular tumor in the liver, which could be either focal nodular hyperplasia, adenoma, or hepatocellular carcinoma (HCC). Even though these lesions were diagnosed as HCC, some of the findings were not compatible with typical HCC. On dynamic CT and MRI, all lesions showed a slight arterial enhancement and did not show early venous washout. All lesions were located near the liver capsule. These findings, along with a history of splenectomy, suggested a diagnosis of hepatic splenosis

The effect of a nutritional education program on the nutritional status of elderly patients in a long-term care hospital in Jeollanamdo province: health behavior, dietary behavior, nutrition risk level and nutrient intake

This study was conducted to assess improvements in nutritional status following the application of nutrition education to elderly patients in a long-term care hospital. The study was carried out from January to May 2009, during which a preliminary survey, a pretest, the application of nutrition education, and a post-test were applied in stages. The number of subjects at pretest was 81, and the number of participants included in the final analysis was 61 (18 men, 43 women), all of whom participated in both the nutrition education program and the post-test. The survey consisted of general demographic items, health behaviors, dietary behaviors, the Nutrition Screening Initiative checklist, and nutrient intake assessment (24 hour recall method). The nutrition education program lasted for four weeks. It included a basic education program, provided once a week, and mini-education program, which was offered daily during lunch times. The survey was conducted before and after the education program using the same assessment method, although some items were included only at pretest. When analyzing the changes in elderly patients after the nutritional education program, we found that, among subjective dietary behaviors, self-rated perceptions of health (P < 0.001) and of depression (P < 0.001) improved significantly and that dietary behavior scores also improved significantly (P < 0.001), while nutritional risk levels decreased. In terms of nutrient intake, subjects' intake of energy, protein, fat, carbohydrate, calcium, phosphorus, iron, vitamin A, thiamin, riboflavin, niacin, and vitamin C all increased significantly (P < 0.001). These results indicated that nutritional education is effective in improving the nutritional status of elderly patients. We hope that the results of this study can be used as preliminary data for establishing guidelines for nutrition management tailored to elderly patients in long-term care hospitals

Transcatheter Arterial Embolization Therapy for a Massive Polycystic Liver in Autosomal Dominant Polycystic Kidney Disease Patients

Polycystic liver is the most common extra-renal manifestation associated with autosomal dominant polycystic kidney disease (ADPKD), comprising up to 80% of all features. Patients with polycystic liver often suffer from abdominal discomfort, dyspepsia, or dyspnea; however, there have been few ways to relieve their symptoms effectively and safely. Therefore, we tried transcatheter arterial embolization (TAE), which has been used in treating hepatocellular carcinoma. We enrolled four patients with ADPKD in Seoul National University Hospital, suffering from enlarged polycystic liver. We embolized the hepatic arteries supplying the dominant hepatic segments replaced by cysts using polyvinyl alcohol particles and micro-coils. The patients were evaluated 12 months after embolization for the change in both liver and cyst volumes. Among four patients, one patient was lost in follow up and 3 patients were included in the analysis. Both liver (33%; 10%) and cyst volume (47.7%; 11.4%) substantially decreased in two patients. Common adverse events were fever, epigastric pain, nausea, and vomiting. We suggest that TAE is effective and safe in treating symptomatic polycystic liver in selected ADPKD patients

Effect of emergency medical service use on time interval from symptom onset to hospital admission for definitive care among patients with intracerebral hemorrhage: a multicenter observational study

Objective This study evaluated whether emergency medical service (EMS) use was associated with early arrival and admission for definitive care among intracerebral hemorrhage (ICH) patients. Methods Patients with ICH were enrolled from 29 hospitals between November 2007 and December 2012, excluding those patients with subarachnoid hemorrhage, traumatic ICH, and missing information. The patients were divided into four groups based on visit type to the definitive hospital emergency department (ED): direct visit by EMS (EMS-direct), direct visit without EMS (non-EMS-direct), transferred from a primary hospital by EMS (EMS-transfer), and transferred from a primary hospital without EMS (non-EMS-transfer). The outcomes were the proportions of participants within early (<1 hr) definitive hospital ED arrival from symptom onset (pS2ED) and those within early (<4 hr) admission from symptom onset (pS2AD). Adjusted odds ratios were calculated to determine the association between EMS use and outcomes with and without inter-hospital transfer. Results A total of 6,564 patients were enrolled. The adjusted odds ratios (95% confidence intervals) for pS2ED were 22.95 (17.73–29.72), 1.11 (0.67–1.84), and 7.95 (6.04–10.46) and those for pS2AD were 5.56 (4.70–6.56), 0.96 (0.71–1.30), and 2.35 (1.94–2.84) for the EMS-direct, EMS-transfer, and non-EMS-direct groups compared with the non-EMS-transfer group, respectively. Through the interaction model, EMS use was significantly associated with early arrival and admission among direct visiting patients but not with transferred patients. Conclusion EMS use was significantly associated with shorter time intervals from symptom onset to arrival and admission at a definitive care hospital. However, the effect disappeared when patients were transferred from a primary hospital
