The complete mitochondrial genome of a Dokdo shrimp, Lebbeus groenlandicus
Lebbeus groenlandicus is a shrimp species indigenous to the Dokdo islands in the East Sea of Korea. We report the 17,399 bp mitochondrial genome (mitogenome) of the species that consists of 13 protein-coding genes, 22 transfer RNAs (tRNAs), 2 ribosomal RNAs (rRNAs), and a control region (CR). A maximum-likelihood tree, constructed with 18 prawn and 45 shrimp mitogenomes, confirmed that L. groenlandicus occupies the most basal position within the Caridea infra-order and is closely related to Pandalidae shrimps
Immediate Laparoscopic Nontransvesical Repair without Omental Interposition for Vesicovaginal Fistula Developing after Total Abdominal Hysterectomy
Immediate laparoscopic nontransvesical repair for vesicovaginal fistula may be an effective and feasible alternative to traditional repair in select patients
Hemophagocytic Lymphohistiocytosis (HLH) Associated with Plasmodium vivax Infection: Case Report and Review of the Literature
Hemophagocytic lymphohistiocytosis (HLH) is an unusual syndrome characterized by fever, hepatosplenomegaly, cytopenias, hypertriglyceridemia, hypofibrinogenemia, and pathologic findings of hemophagocytosis in the bone marrow and other tissues. HLH may be familial or associated with different types of infections, autoimmune disorders, or malignancies. Infection-associated HLH has been reported in various viral, bacterial, fungal, and parasitic infections, and case reports of parasitic infections implicated in HLH include rare cases from Plasmodium vivax infection, which occasionally affects both military personnel and civilians in Korea. We describe an unusual case of HLH resulting from Plasmodium vivax infection and review the literature. This case suggests that clinical suspicion of HLH is important when P. vivax infection is accompanied by cytopenias. Administration of antimalarial drugs may prevent irreversible end organ damage resulting from P. vivax-associated HLH
Multidisciplinary approach for hepatocellular carcinoma arising from cirrhotic liver with Budd-Chiari syndrome: a case report
Budd-Chiari syndrome (BCS) is defined by the obstruction of the hepatic venous outflow between the small hepatic veins and the junction of the inferior vena cava (IVC) with the right atrium. BCS with IVC obstruction occasionally progresses to hepatocellular carcinoma (HCC). Here, we report the case of a patient with HCC arising from a cirrhotic liver with BCS, in whom the hepatic portion of the IVC was obstructed, and who had a favorable outcome with a multidisciplinary approach and IVC balloon angioplasty
Comparative Genome and Evolution Analyses of an Endangered Stony Coral Species Dendrophyllia cribrosa Near Dokdo Islands in the East Sea
Stony corals often harbor intracellular photosynthetic dinoflagellate algae that receive dissolved inorganic nutrients. However, Dendrophyllia cribrosa is a nonsymbiotic stony coral distributed in the western Pacific. We assembled a chromosome-level D. cribrosa genome using PacBio and Hi-C technologies. The final assembly was 625 Mb, distributed on 14 chromosomes, and contained 30,493 protein-coding genes. The Benchmarking Universal Single-Copy Orthologs analysis revealed a percentage of 96.8 of the metazoan genome. A comparative phylogenetic analysis revealed that D. cribrosa, which lacks symbionts, evolved to acquire cellular energy by expanding genes related to acyl-CoA metabolism and carbohydrate transporters. This species also has expanded immune-related genes involved in the receptor protein tyrosine kinase signaling pathway. In addition, we observed a specific expansion of calcification genes, such as coral acid-rich proteins and carbonic anhydrase, in D. cribrosa. This high-quality reference genome and comparative analysis provides insights into the ecology and evolution of nonsymbiotic stony corals
Sedative and analgesic effects of intravenous xylazine and tramadol on horses
This study was performed to evaluate the sedative and analgesic effects of xylazine (X) and tramadol (T) intravenously (IV) administered to horses. Six thoroughbred saddle horses each received X (1.0 mg/kg), T (2.0 mg/kg), and a combination of XT (1.0 and 2.0 mg/kg, respectively) IV. Heart rate (HR), respiratory rate (RR), rectal temperature (RT), indirect arterial pressure (IAP), capillary refill time (CRT), sedation, and analgesia (using electrical stimulation and pinprick) were measured before and after drug administration. HR and RR significantly decreased from basal values with X and XT treatments, and significantly increased with T treatment (p < 0.05). RT and IAP also significantly increased with T treatment (p < 0.05). CRT did not change significantly with any treatments. The onset of sedation and analgesia were approximately 5 min after both X and XT treatments; however, the XT combination produced a longer duration of sedation and analgesia than X alone. Two horses in the XT treatment group displayed excited transient behavior within 5 min of drug administration. The results suggest that the XT combination is useful for sedation and analgesia in horses. However, careful monitoring for excited behavior shortly after administration is recommended
Prognosis according to the timing of percutaneous coronary intervention in non-ST segment elevation myocardial infarction, based on the Korean Acute Myocardial Infarction Registry (KAMIR)
Background: Patients with acute coronary syndrome without ST-segment elevation (ACS-
-NSTE) are at risk for adverse cardiac events. Based on data in the Korean Acute Myocardial
Infarction Registry (KAMIR), we analyzed the prognosis according to the timing of percutaneous
coronary intervention (PCI) in patients with NSTEMI in Korea.
Methods and results: 2,455 patients with NSTEMI in KAMIR were classified according to
the time interval from the onset of cardiac symptoms to PCI. Patients in Group I underwent
PCI within 24 hours of the onset of symptoms; in Group II between 24 and 48 hours; and in
Group III after 48 hours. Major adverse cardiac events (MACEs) are defined as cardiac death,
non-cardiac death, myocardial infarction, revascularization and coronary-artery bypass graft
surgery. The MACEs were compared between groups. Of the 2,455 patients, 743 (30.2%) were
assigned to Group I, 583 (23.7%) to Group II, and 1,129 (45.9%) to Group III. The total
incidence of MACEs was higher in Group I than Group III, and similar between Groups I and
II (Group I: 15.1%, Group II: 14.4%, Group III: 11.6%, p = 0.053). The incidence of MACEs
in the intermediate TIMI risk score group had decreased as the intervention time was delayed.
Conclusions: The prognosis according to the timing of PCI in patients with NSTEMI was
similar based on the data in KAMIR. TIMI risk score was related to a high incidence of
MACEs. (Cardiol J 2011; 18, 4: 421–429
Different contribution of extent of myocardial injury to left ventricular systolic and diastolic function in early reperfused acute myocardial infarction
BACKGROUND: We sought to investigate the influence of the extent of myocardial injury on left ventricular (LV) systolic and diastolic function in patients after reperfused acute myocardial infarction (AMI).
METHODS: Thirty-eight reperfused AMI patients underwent cardiac magnetic resonance (CMR) imaging after percutaneous coronary revascularization. The extent of myocardial edema and scarring were assessed by T2 weighted imaging and late gadolinium enhancement (LGE) imaging, respectively. Within a day of CMR, echocardiography was done. Using 2D speckle tracking analysis, LV longitudinal, circumferential strain, and twist were measured.
RESULTS: Extent of LGE were significantly correlated with LV systolic functional indices such as ejection fraction (r��=��-0.57, p��<��0.001), regional wall motion score index (r��=��0.52, p��=��0.001), and global longitudinal strain (r��=��0.56, p��<��0.001). The diastolic functional indices significantly correlated with age (r��=��-0.64, p��<��0.001), LV twist (r��=��-0.39, p��=��0.02), average non-infarcted myocardial circumferential strain (r��=��-0.52, p��=��0.001), and LV end-diastolic wall stress index (r��=��-0.47, p��=��0.003 with e') but not or weakly with extent of LGE. In multivariate analysis, age and non-infarcted myocardial circumferential strain independently correlated with diastolic functional indices rather than extent of injury.
CONCLUSIONS: In patients with timely reperfused AMI, not only extent of myocardial injury but also age and non-infarcted myocardial function were more significantly related to LV chamber diastolic function.ope
