Abstract
BACKGROUND AND AIM Several uncontrolled studies have reported on the efficacy of adsorptive depletion of peripheral blood granulocytes and monocytes/macrophages (GM) in patients with moderate or severe ulcerative colitis. This study was to compare the efficacy and safety of intensive GMA with intensive intravenous prednisolone in patients with severe ulcerative colitis. METHODS Seventy patients with clinical activity index 10-23 were randomly assigned to intensive GMA with the Adacolumn, at 2 sessions/week in the first 3 weeks and then 1 session/week for up to 11 sessions (n = 35) or intravenous prednisolone, 40-60 mg/day for 5-10 days (n = 35). No patient received immunomodulators within 8 weeks prior to entry. Clinical response based on intention to treat was assessed at weeks 2, 6 and 12. RESULTS Four patients in the prednisolone group and two patients in the GMA group discontinued in week 1. At weeks 2, 6 and 12, the remission (clinical activity index < or = 4) rates (%) in the GMA group were 17.1, 54.4, 74.3, respectively. The corresponding values in the prednisolone group were 25.7, 51.4 and 48.6. Further, at week 12, 27 patients (77%) in the GMA group and 5 patients (14%) in the prednisolone group were steroid free (P = 0.0076). In the GMA group, flushing and light-headedness were observed in 5 patients versus typical steroid side effects in 29 patients of the prednisolone group. CONCLUSIONS In this clinical response to GMA was comparable or better than prednisolone. Further, the response to GMA was slower than to intravenous prednisolone, but was more sustainable than the latter.

Abstract
An 80-year-old man with acute type A aortic dissection, who was preoperatively observed in the intensive care unit, suddenly became unresponsive. The patient was immediately intubated, but a pulse check was delayed because the cardiac monitor seemingly showed a normal sinus rhythm. Bedside echocardiography, while continuing cardiopulmonary resuscitation, revealed massive pericardial effusion. It indicated the patient's cardiac arrest was pulseless electrical activity (PEA) due to cardiac tamponade. After pericardiocentesis, a perfusion rhythm was restored with palpable distal pulse. He successfully underwent a prosthetic graft replacement of the ascending aorta and was discharged after physical rehabilitation.

Abstract
BACKGROUND Granulocyte, monocyte/macrophage adsorptive apheresis is a novel treatment for active ulcerative colitis. However, as yet no study has reported on a subset of patients who might respond well to granulocyte, monocyte/macrophage adsorptive apheresis therapy. AIM To identify factors affecting clinical and endoscopic efficacies of granulocyte, monocyte/macrophage in patients with ulcerative colitis. METHODS Fifty consecutive patients with active ulcerative colitis initially received five granulocyte, monocyte/macrophage adsorptive apheresis sessions with the Adacolumn over five consecutive weeks. Patients who improved without achieving remission received five additional granulocyte, monocyte/macrophage adsorptive apheresis sessions. RESULTS One week after the last granulocyte, monocyte/macrophage adsorptive apheresis session, 26 (52%) and 17 patients (34%) achieved clinical and endoscopic remission, respectively. In the multivariate analysis, the dose of prednisolone administered at entry and the cumulative dose of prednisolone administered before entry were independent significant factors for both clinical and endoscopic remission, negatively impacted the efficacy of granulocyte, monocyte/macrophage adsorptive apheresis. Age, gender, duration of ulcerative colitis, number of prior relapses, duration of current exacerbation, extent and severity of ulcerative colitis, extra-intestinal manifestations, entry haematology values and C-reactive protein did not affect the outcome. CONCLUSIONS Based on the outcomes of this study, it appears that steroid-naïve patients and patients on low dose steroid and short duration of exposure respond to granulocyte, monocyte/macrophage adsorptive apheresis. Further studies in larger cohorts of patients should strengthen our findings.

Abstract
The critical importance of the junction between touching or closely adjacent Ag nanoparticles associated with single-molecule sensitivity (SMS) in surface-enhanced Raman scattering (SERS) was confirmed via the following observations: (1) an additional peak is observed in elastic scattering only for the SERS-active state, which originated from absorption of adsorbates, (2) local- and far-field evaluation using a finite difference time domain method could reproduce this extra peak and anticipate the significantly enhanced field even inside the adsorbates sitting at the junction through an increased coupling of the localized surface plasmons, and (3) in addition to enhanced fluorescence of adsorbed dye, an inelastic scattering peak was observed and attributed to the metal surface electron. Concerning the chemical enhancement in SERS, Cl- anions activate the Ag-Cl-R6G (rhodamine) samples by inducing intrinsic electronic interaction between Ag and R6G molecules. This electronic interaction is irreversibly quenched by the addition of thiosulfate anions which dissolve Ag+ cations while the electromagnetic (EM) effect remains intact.

Abstract
BACKGROUND Homocysteine and advanced glycation end-products (AGEs), which accumulate in chronic kidney disease (CKD), are recently proposed cardiovascular risk factors. In this study, we evaluated the association between changes in calculated intima media (cIM) area of the common carotid artery during the first year of dialysis therapy and plasma total homocysteine (tHcy) level as well as circulating AGEs such as plasma pentosidine level. METHODS We studied 63 CKD patients (38 males) aged 52 +/- 12 years at a time-point close to start of dialysis treatment and after 12 months of dialysis treatment (41 on peritoneal and 22 on hemodialysis). The tHcy and plasma pentosidine levels were measured by HPLC. Change in cIM area was evaluated by non-invasive B mode ultrasonography. Malnutrition was assessed by subjective global assessment (SGA). RESULTS At basal, 70% of the patients had carotid plaques, 32% had symptomatic CVD, 38% had malnutrition, 30% had inflammation (CRP > or = 1 mg/dl) and 23% had diabetes mellitus, respectively. At baseline, the mean plasma pentosidine levels were similar in the patients with and without carotid plaques (36 +/- 21 vs 36 +/- 19 pmol/mg albumin, respectively), whereas the median plasma tHcy was significantly lower in the patients with carotid plaques than in the patients without carotid plaques (32 +/- 21 vs 52 +/- 42 pmol/l, p < 0.01, respectively). The prevalence of hyperhomocysteinemia (tHcy level > 13.7 micromol/l) was 95%. In univariate analysis, the change in cIM area during the first year of dialysis was significantly correlated with basal plasma pentosidine level (p = 0.31, p = 0.01), but not with basal tHcy (p = -0.11). However, neither pentosidine nor tHcy levels were correlated with cIM area at basal or at 12 months. In a stepwise multiple regression model, age and plasma pentosidine content, but not the tHcy level, associated with changes in the cIM area. CONCLUSION Progression of atherosclerosis, as indicated by changes in carotid intima-media area during the course of dialysis treatment, was associated with pentosidine, but not with tHcy, levels at baseline in these CKD patients. This suggests that the accumulation of AGEs in CKD patients may have a role in the pathogenesis of CVD in these patients. Since almost all CKD patients have hyperhomocysteinemia, this finding, however, does not exclude a role ofhomocysteine as a risk factor for CVD in CKD patients.

Abstract
Y-box-binding protein 1 (YB-1), which is a member of the DNA-binding protein family containing a cold-shock domain, has pleiotropic functions in response to various environmental stimuli. As we previously showed that YB-1 is a global marker of multidrug resistance in ovarian cancer and other tumor types. To identify YB-1-regulated genes in ovarian cancers, we investigated the expression profile of YB-1 small-interfering RNA (siRNA)-transfected ovarian cancer cells using a high-density oligonucleotide array. YB-1 knockdown by siRNA upregulated 344 genes, including MDR1, thymidylate synthetase, S100 calcium binding protein and cyclin B, and downregulated 534 genes, including CXCR4, N-myc downstream regulated gene 1, E-cadherin and phospholipase C. Exogenous serum addition stimulated YB-1 translocation from the cytoplasm to the nucleus, and treatment with Akt inhibitors as well as Akt siRNA and integrin-linked kinase (ILK) siRNA specifically blocked YB-1 nuclear localization. Inhibition of Akt activation downregulated CXCR4 and upregulated MDR1 (ABCB1) gene expression. Administration of Akt inhibitor resulted in decrease in nuclear YB-1-positive cancer cells in a xenograft animal model. Akt activation thus regulates the nuclear translocation of YB-1, affecting the expression of drug-resistance genes and other genes associated with the malignant characteristics in ovarian cancer cells. Therefore, the Akt pathway could be a novel target of disrupting the nuclear translocation of YB-1 that has important implications for further development of therapeutic strategy against ovarian cancers.

Abstract
To clarify some characteristics of phosphatidylinositol glycan-class A gene (PIG-A) mutations in aplastic anemia (AA) and myelodysplastic syndrome (MDS) patients compared with those in paroxysmal nocturnal hemoglobinuria (PNH) patients, we investigated PIG-A mutations in CD59- granulocytes and CD48- monocytes from seven AA, eight MDS, and 11 PNH Japanese patients. The most frequent base or type abnormalities of the PIG-A gene in AA and MDS patients were base substitutions or missense mutations, respectively, and deletions or frameshift mutations, respectively, in PNH patients. Several PIG-A mutations, most of which were statistically minor, were found in glycosylphosphatidylinositol-negative cells from all AA and MDS patients but not from all PNH patients. However, the common PIG-A mutations during the clinical course between CD59- granulocytes and/or CD48- monocytes from each AA or MDS patient, except for Case 5, were not found. PIG-A mutations were different between the granulocytes and monocytes from five AA and five MDS patients. Our results indicate that there were some characteristics of PIG-A mutations in AA and MDS patients compared with PNH patients and that several minor PNH clones in these patients occurred at random during the clinical course. This partly explains the transformation of AA or MDS to PNH at intervals.

Abstract
Reactivation of chronic hepatitis B virus (HBV) infection in patients undergoing chemotherapy is well-documented, but reactivation during imatinib mesylate treatment has not been reported. This study reports a 54-year-old man, without prior liver dysfunction but with chronic HBV infection, in whom fatal HBV reactivation occurred during treatment of chronic myeloid leukemia (CML) with imatinib mesylate. He developed fulminant hepatitis followed by marked elevation of HBV DNA polymerase, probably from the lymphocytopenic and immunosuppressive status induced by imatinib mesylate. Imatinib mesylate is widely used to treat CML patients. Although therapy with imatinib mesylate is generally well tolerated, the case presented here suggests that viral reactivation should be considered, even when using imatinib mesylate to treat CML.

Abstract
An 8-year-old girl with preexisting chronic renal failure (CRF) due to bilateral renal hypoplasia presented with edema, gross hematuria and acute deterioration of renal function. The diagnosis of poststreptococcal acute glomerulonephritis (PSAGN) was made based on clinical presentation, red blood cell casts, low level of C3 and elevated antistreptolysin 0 titer. Her course was prolonged with serum creatinine increased from the baseline level of 1.1 mg/dl to 2.2 mg/dl, returning toward the baseline level (1.2 mg/dl) after one month. Serum creatinine then started to increase again. The slope of creatinine clearance over time became steeper after the episode of PSAGN. A severe course of PSAGN and subsequent deterioration of renal function have previously been reported in patients with diabetic nephropathy or focal glomerulosclerosis. The present case along with a literature review suggests that individuals with fewer nephrons are at higher risk of severe course and outcome of PSAGN. Conversely, patients with severe PSAGN may be born with fewer nephrons due to low birth weight, unrecognized renal hypoplasia or other unknown causes.

Abstract
CHO cells transfected with high-affinity 5HT receptors were used to detect and identify the release of serotonin from taste buds. Taste cells release 5HT when depolarized or when stimulated with bitter, sweet, or sour tastants. Sour- and depolarization-evoked release of 5HT from taste buds is triggered by Ca2+ influx from the extracellular fluid. In contrast, bitter- and sweet-evoked release of 5HT is triggered by Ca2+ derived from intracellular stores.

Abstract
An ulnar recurrent adipofascial flap was raised and turned over to reconstruct massive defects around the elbow and forearm after wide resection of malignant tumours. Compared to the fasciocutaneous flap, the ulnar recurrent adipofascial flap has the following advantages: (1) a larger flap can be harvested without the problem of primary closure of the donor site, (2) the contour and scar of the donor site is reasonably acceptable since no tension is presented, (3) the flap can be turned over to cover a wider area, and (4) debulking of the flap can be performed during the operation if needed. The rotation arc of the ulnar recurrent adipofascial flap reaches a wide region, including the distal one-half of the upper arm, the elbow, and the proximal two-thirds of the forearm. Sensory deficit in the forearm was avoided in our patients because meticulous separation and preservation of the medial cutaneous nerve of the forearm was achieved without jeopardising the blood supply to the flap. The ulnar recurrent adipofascial flap is an easy and reliable option for one-stage reconstruction of massive defects around the elbow.
