Abstract
A six-year-old, neutered, female golden retriever was presented with generalised, dark purple to black cutaneous nodules and gastrointestinal haemorrhage. Histopathologically, all cutaneous nodules were diagnosed as benign cavernous haemangiomas. Endoscopic analysis revealed similar nodules in the oesophagus, stomach and duodenum. At laparotomy, similar nodules were seen on the visceral peritoneal lining of abdominal organs. Metastatic haemangiosarcoma was ruled out based on histological features and lack of primary tumour in spleen, liver or heart ultrasonographically. Blood loss associated with gastrointestinal haemorrhage was managed with blood transfusion. To the authors' knowledge, this is the first canine case of multi-system progressive angiomatosis resembling blue rubber bleb nevus syndrome in humans.

Abstract
BACKGROUND When the kidney from a living donor with a double inferior vena cava (IVC) is harvested for renal transplantation, the short length of the renal vein may eventually create a technical problem for graft implantation. Herein, we have reported a rare case of renal vein extension using an autologous renal vein in a living donor with a double IVC. CASE REPORT A 70-year-old man with end-stage renal disease owing to autosomal-dominant polycystic kidney disease underwent a living donor kidney graft from his wife who had a double IVC. Because of the enlarged kidneys, the patient underwent a bilateral native nephrectomy with concomitant renal transplantation to create space in the pelvis. At nephrectomy, the recipient's renal vein was used to extend the donor renal vein. On the back table, the vein graft was sutured to the donor renal vein, permitting a 3.0-cm extension. RESULTS The transplantation was performed safely without any complications; the recipient's renal function and blood flow were excellent after the operation. CONCLUSION This case illustrated that an autologous renal vein graft is a preferable option to extend of short donor renal vein for recipients who require a simultaneous native nephrectomy.

Abstract
AIM We investigated the clinical relevance of immune monitoring by a multiparametric mixed lymphocyte reaction (MLR) assay, wherein the number and phenotype of alloreactive precursors can be quantified by combining the results of carboxyfluorescein diacetate succinimidyl ester labeling and flow cytometry analysis. METHODS In 51 adult patients undergoing living donor liver transplantation (OLT), immunosuppressive drugs were dosed on the basis of immune monitoring by the MLR assay (optimized protocol: group O). In 64 other patients, the agents were prescribed according to empirical regimens (empirical protocol: group E). In group O, MLR assays were performed at 2- to 4-week intervals until 3 months after OLT and thereafter at 3- to 6-month intervals. Therapeutic adjustments for immunosuppressants were determined by tapering the doses in cases of anti-donor hyporesponsiveness for both CD4+ and CD8+ T-cell subsets. RESULTS The 1-year patient and graft survivals in groups O versus E were 90.2% versus 76.6%, respectively. The incidence of acute rejection episodes (ARE) among group O (13.7%) were lower than in cohort E (28.1%). None of the patients in group O while four patients (3%) in group E already have shown chronic rejection to date. The incidences of bacteremia and fungal infections in group O (9.8% and 7.5%, respectively) were lower than in cohort E (18.8% and 12.6%, respectively). CONCLUSION A multiparametric MLR assay may facilitate the development of adequate immunosuppressive regimens.

Abstract
The vascular abnormalities of recipients are associated with reconstructive difficulties with an increased risk of postoperative complications. We performed an orthotopic liver transplantation that required a complex vascular reconstruction using donor vascular grafts. A patient with hepatitis B virus cirrhosis received a liver from a brain-dead donor. Dynamic computed tomography revealed complete obstruction of the portal vein due to thrombosis as well as narrowing of the hepatic arteries. We employed orthotopic liver transplantation using the piggy-back technique with complex reconstruction of the portal vein and the hepatic arteries. For portal vein reconstruction, we used the donor's iliac vein as an interpositional conduit from the recipient's gastric coronary vein to graft the portal vein. The hepatic arteries of the graft were reconstructed at the back-table before anastomosis to the side of superior mesenteric artery using an interpositional conduit of the donor's external iliac artery. All postoperative studies revealed good graft function with an excellent blood flow through all vascular anastomoses during the first year postoperatively.

Plasmid DNA is released from nanosized acicular material surface by low molecular weight oligonucleotides: exogenous plasmid acquisition mechanism for penetration intermediates based on the Yoshida effect. Appl Microbiol Biotechnol 2008; 80:813-21. [PMID: 18704395 DOI: 10.1007/s00253-008-1637-5] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2008] [Revised: 07/24/2008] [Accepted: 07/30/2008] [Indexed: 10/21/2022]
Abstract
When a colloidal solution consisting of nanosized acicular material and bacterial cells is stimulated with sliding friction at the interface between the hydrogel and interface-forming material where the frictional coefficient increases rapidly, the nanosized acicular material accompanying the bacterial cells forms a penetration intermediate. This effect is known as the Yoshida effect in honor of its discoverer. Through the Yoshida effect, a novel property in which penetration intermediates incorporate exogenous plasmid DNA has been identified. This report proposes a possible mechanism for exogenous plasmid acquisition by penetration intermediates in the Yoshida effect. Escherichia coli cells, pUC18, and chrysotile were used as recipient cells, plasmid DNA, and nanosized acicular material, respectively. Even when repeatedly washing the mixture consisting of pUC18 and chrysotile, transformation efficiency by pUC18 was stable. Accordingly, pUC18 adsorbed onto chrysotile was introduced into recipient E. coli cells. At saturation, the amount of pUC18 adsorbed onto chrysotile was 0.8-1.2 microg/mg. To investigate whether pUC18 adsorbed on chrysotile is replicated by polymerase, polymerase chain reaction (PCR) was carried out with the chrysotile. Amplification of the beta-lactamase gene coded in pUC18, which was adsorbed onto chrysotile, was strongly inhibited. This suggests that DNA adsorbed onto chrysotile is not replicated in vivo. When we searched for substances to release pUC18 adsorbed onto chrysotile, we found that a 300-bp single- or double-stranded segment of DNA releases pUC18 from chrysotile. Competitive adsorption onto chrysotile between double-stranded DNA and pUC18 was then examined through the Yoshida effect. The 310- and 603-bp double-stranded nucleotides caused 50% competitive inhibition at the same molar ratio with pUC18. Hence, the adsorbed region of pUC18 is about 300 bp in length. As the culture period for recipient cells increases, transformation efficiency decreases while the expression levels of small RNA of 300-600 bp also decrease. These results suggest that pUC18 adsorbed onto chrysotile can be released by 300-bp small RNA, replicated by DNA polymerase, and transferred to daughter cells.

Abstract
Validation is often defined as the process of determining the degree to which a model is an accurate representation of the real world from the perspective of its intended uses. Validation is crucial as industries and governments depend increasingly on predictions by computer models to justify their decisions. We propose to formulate the validation of a given model as an iterative construction process that mimics the often implicit process occurring in the minds of scientists. We offer a formal representation of the progressive build-up of trust in the model. Thus, we replace static claims on the impossibility of validating a given model by a dynamic process of constructive approximation. This approach is better adapted to the fuzzy, coarse-grained nature of validation. Our procedure factors in the degree of redundancy versus novelty of the experiments used for validation as well as the degree to which the model predicts the observations. We illustrate the methodology first with the maturation of quantum mechanics as the arguably best established physics theory and then with several concrete examples drawn from some of our primary scientific interests: a cellular automaton model for earthquakes, a multifractal random walk model for financial time series, an anomalous diffusion model for solar radiation transport in the cloudy atmosphere, and a computational fluid dynamics code for the Richtmyer-Meshkov instability.

Abstract
An 8-year-old female Shih Tzu was presented with weight loss and vomiting. Alanine aminotransferase was high and abdominal radiographs revealed hepato- and splenomegaly. Mild anaemia, neutrophilia with left shift, eosinophilia, a thrombocytosis with dysplastic features of eosinophils and platelets, were detected. The animal was initially considered to have hepatitis and was treated accordingly, but clinical signs persisted. Histological examination of liver biopsy samples showed disruption of the hepatic lobule, with extensive infiltration by haemopoietic cells. Further investigation of the bone marrow suggested a diagnosis of myelodysplastic syndrome. The animal was treated with cytarabine ocfosfate, a prodrug of cytosine arabinoside, and appeared to recover.

Abstract
PURPOSE The transradial approach is not so popular in cerebral angiography. The purpose of this study was therefore to present our experience of success rate and safety of this method. MATERIAL AND METHODS From December 1998 to June 2001, 526 carotid and vertebral angiographies with DSA were performed via the radial artery. A 1.4-mm catheter was used through a 1.4-mm introducer sheath. We evaluated the procedure as successful if sufficient images for diagnosis were obtained of the bilateral carotid arteries and unilateral vertebral artery. Each patient was reassessed for any complications, occurring until the next morning. The length of time needed for an examination was measured in the last 10 cases. RESULTS In all but 5 cases, the procedures were evaluated as successful (99.0%). Unsuccessful cases manifested severe pain at the radial puncture, angiospasm at the radial artery, loop formation at the radial artery, occlusion at the subclavian artery, and an aberrant right subclavian artery. No severe complications including neurological ones were encountered. Minor complications were noted in 17 cases (3.2%): 4 cases of thrombus at the ulnar artery, 1 angiospasm at the radial artery, and 12 cases of small hematoma at the puncture site. The radial approach took 14 min less in the common carotid study and 3 min 30 s less in the internal carotid study than by the femoral approach. CONCLUSION The transradial approach enabled selective studies for carotid and vertebral angiography with a high success rate and safety with few complications.

Abstract
In vitro proliferation and functional activation of V alpha 24NKT cells following stimulation with alpha-galactosylceramide (alpha-GalCer)-pulsed dendritic cells (DCs) have been observed. Because little is known about the molecular events on DCs following interaction with alpha-GalCer, we performed gene expression profiling of 2400 genes in monocytes and monocyte-derived immature DCs pulsed with alpha-GalCer (alpha-GalCer-imDCs). Overall, the expression levels of 48 genes were up-regulated and 28 were down-regulated in alpha-GalCer-imDCs. Semiquantitative RT-PCR analysis on monocytes, imDCs, alpha-GalCer-imDCs, and mature DCs confirmed the up- and down-regulation of the mRNA expression levels of 28 selected genes. Notably, we identified the specific up-regulation of mRNA expression levels of ribonuclease A and collapsin response mediator protein upon the stimulation of imDC with alpha-GalCer, suggesting a novel immunomodulating effect of alpha-GalCer on imDCs. In this study, we used imDCs prepared by culturing of monocytes with GM-CSF and IL-4 for 5 days and mDCs prepared by further culturing of imDCs with TNF alpha for two extra days.

Abstract
The effects of simultaneous administration of some binary mixtures of seven natural and synthetic oestrogenic substances (17beta-estradiol, estrone, bisphenol A, butylbenzyl phthalate, endosulfan, methoxychlor and pentachlorophenol) on the cellular proliferation of human breast cancer MCF-7 cells in-vitro (a modified E-screen assay) have been measured. To assess the presence or absence of interactions of the two agents, the data were analysed on the basis of a graphical method in which the types and extents of interactions were described by response-surface diagrams. Of the nine combinations of the agents examined, synergistic interaction was evident for the combination of 17beta-estradiol and bisphenol A, whereas the remaining eight combinations were weakly synergistic, additive and/or weakly antagonistic in the dose-range tested.

Abstract
A method for bioremediation of chlorinated dibenzo-p-dioxins (CDDs) and dibenzofurans (CDFs) by a carbazole-utilizing bacterium, Pseudomonas sp. strain CA10, was developed. CA10 cells transferred to carbon- and nitrogen-free mineral medium supplemented with 1 mg carbazole (CAR)/ml grew rapidly during the first 2 days; and the cells at the end of this rapid growth period showed the highest 2,3-dichlorodibenzo-p-dioxin (2,3-Cl2DD)-degrading activity. The CA10 cells pregrown for 2 days efficiently degraded 2,3-Cl2DD in aqueous solution at either 1 ppm or 10 ppm. The effect of inoculum density on the efficiency of 2,3-Cl2DD degradation was investigated in a soil slurry microcosm [ratio of soil:water = 1:5 (w/v)]. The results showed that a single inoculation with CA10 cells at densities of 10(7) CFU/g soil and 10(9) CFU/g soil degraded 46% and 80% of 2,3-Cl2DD, respectively, during the 7-day incubation. The rate of degradation of each CDD congener, 2-ClDD, 2,3-Cl2DD, and 1,2,3-Cl3DD (1 ppm each) by strain CA10 in the soil slurry system was not significantly influenced by the coexistence of the other congeners. Using this soil slurry system, we tried an experimental bioremediation of the actual dioxin-contaminated soil, which contained mainly tetra- to octochlorinated dioxins. Although the degradation rate of total CDD and CDF congeners by a single inoculation with CA10 cells was 8.3% after a 7-day incubation, it was shown that strain CA10 had a potential to degrade tetra- to hepta-chlorinated congeners including the most toxic compound, 2,3,7,8-tetrachlorinated dibenzo-p-dioxin.

Abstract
A 72-year-old man presented with paroxysmal and transient involuntary movements, or "limb shaking". The attacks occurred alternately from one side of the body to the other and ceased spontaneously. Surface EMG study showed synchronous grouping discharges in multiple limb muscles, being compatible with hemiballism-hemichorea. Cerebral angiography demonstrated marked stenosis of the bilateral internal carotid arteries. Bilateral carotid endarterectomy led to complete disappearance of the involuntary movements. Alternating paroxysmal hemiballismhemichorea might be a transient ischemic attack, and alternating striatal dysfunction induced by cerebral hemodynamic or microembolic ischemia probably plays a central role in the occurrence of such involuntary movements.
