TLS and PRMT1 synergistically coactivate transcription at the survivin promoter through TLS arginine methylation.

TLS (Translocated in LipoSarcoma), also termed FUS, is a multifunctional protein implicated in diverse cellular events such as maintaining genome integrity and regulating gene expression. We have focused on the role of TLS as a coregulator in transcriptional regulation. In the process of investigating TLS-binding proteins, we found that PRMT1 (protein arginine methyltransferase 1) was in complex with TLS.

Eyes with basic dorsal and specific ventral regions in the glacial Apollo, Parnassius glacialis (Papilionidae).

Recent studies on butterflies have indicated that their colour vision system is almost species specific. To address the question of how this remarkable diversity evolved, we investigated the eyes of the glacial Apollo, Parnassius glacialis, a living fossil species belonging to the family Papilionidae. We identified four opsins in the Parnassius eyes--an ultraviolet- (PgUV), a blue- (PgB), and two long wavelength (PgL2, PgL3)-absorbing types--and localized their mRNAs within the retina.

[Three cases of squamous cell carcinoma of the esophagus who underwent argon plasma coagulation as salvage treatment for locoregional failure or remnant tumor after chemoradiotherapy].

We report 3 cases of locoregional failure or remnant esophageal squamous cell carcinoma after chemoradiotherapy that were successfully treated by argon plasma coagulation (APC) as a salvage treatment. Ablation was performed using argon plasma coagulation APC300 (ERBE). A power setting of 60W and an argon gas flow of 1.

[A successful resected case of far-advanced cancer at the esophagogastric junction by chemoradiotherapy with docetaxel, nedaplatin and 5-fluorouracil].

The patient, a 73-year-old male, was admitted to our hospital because of dysphagia. A far-advanced cancer was diagnosed at the esophagogastric junction by upper gastrointestinal endoscopic examination. Pathological biopsy examinations revealed poorly-differentiated adenocarcinoma.

[Graft-versus-leukemia effect by lymphocytes from the first donor after second cord blood transplantation in a patient with T-lymphoblastic lymphoma].

A 19-year-old girl with T-lymphoblastic lymphoma (T-LBL) was referred to our hospital because of refractory disease. After complete remission was achieved by the JALSG ALL-97 protocol, she received a bone marrow transplantation (BMT) from an unrelated, HLA-matched donor with myeloablative conditioning. Four months after BMT, T-LBL relapsed and donor lymphocyte infusion was ineffective.

Expression analysis of circadian genes in oocytes and preimplantation embryos of cattle and rabbits.

We previously showed that circadian genes clock, bmal1, cry1, cry2, per1, and per2 are expressed and function as maternal mRNA regulating events in the oocytes and preimplantation embryos of mice. Recent evidence indicates however that either or both expression profiles of circadian genes in some tissues, and transcript sequences of circadian genes, differ to generate the physiological differences between diurnal and nocturnal species. We therefore investigated the expression profiles of circadian genes in oocytes and preimplantation embryos of species other than mice, namely cattle and rabbits, representing diurnal and nocturnal species, respectively, and determined the protein sequences of circadian genes in these species.

Regional distribution of cytochrome p450 mRNA expression in the liver and small intestine of cynomolgus monkeys.

The cynomolgus monkey is used to study drug metabolism because of its evolutionary closeness to humans. Despite their importance, regional distribution of cytochrome P450 (CYP) enzymes including CYP3As in the liver and small intestine, the major sites of drug metabolism, has not been fully investigated in cynomolgus monkeys. In this study, we measured mRNA expression levels of 14 CYPs in the CYP1, 2, and 3 subfamilies, including orthologs of human CYP3A4 and CYP3A5, in the liver and small intestine of cynomolgus monkeys.

[A case of recurrence with liver metastasis after total gastrectomy for StageIA gastric carcinoma successfully treated with S-1/CDDP combination followed by S-1 chemotherapy].

A 72-year-old man underwent total gastrectomy for gastric carcinoma. Postoperative staging was Stage IA. One year after operation, abdominal CT revealed a metastatic tumor in the left lateral posterior segment of the liver.

Histiocytic sarcoma and underlying chronic myelomonocytic leukemia: a proposal for the developmental classification of histiocytic sarcoma.

A 70-year-old male was admitted because of back pain due to peri-vertebral tumors. The histologic picture of a needle-biopsied tumor specimen showed pleomorphic large cell infiltration into the collagen fibers. On immunohistochemistry, these abnormal cells were positive for CD68, CD163 and lysozyme but negative for CD1a, 21, 30, and S100.

[Therapeutic efficacy of cyclosporin A for refractory angioimmunoblastic T cell lymphoma].

The prognosis of angioimmunoblastic T cell lymphoma (AITL) is poor because of chemotherapy-resistance and the short duration of remission. In recent years, cyclosporin A (CyA) has been employed as a alternative treatment for AITL in some patients with the rationale that CyA inhibits the activity and proliferation of neoplastic T cells. We herein report 4 chemotherapy-resistant AITL patients who were treated with oral CyA.

Modular necks improve the range of hip motion in cases with excessively anteverted or retroverted femurs in THA.

Background: Anteversion of an acetabular component often is difficult to ascertain in patients with THA in whom excessively anteverted or retroverted femurs may result in limited ROM or risk of dislocation. Restriction of motion, however, is determined by the combination of version of both components.

Questions/purposes: We therefore determined the combined anteversion values that provide adequate ROM.

Fulminant sepsis caused by Bacillus cereus in patients with hematologic malignancies: analysis of its prognosis and risk factors.

Bacillus cereus is a growing concern as a cause of life-threatening infections in patients with hematologic malignancies. However, the risk factors for patients with unfavorable outcomes have not been fully elucidated. At our institution, we observed the growth of B.

Acetabular retroversion in developmental dysplasia of the hip.

Background: Patients with developmental dysplasia of the hip are prone to the development of degenerative changes in the affected hip. The aim of this study was to evaluate the prevalence, morphological features, and clinical relevance of acetabular retroversion in these patients.

Methods: We investigated the version and morphological features of the acetabulum using pelvic radiographs and computed tomography images of ninety-six hips in fifty-nine patients with developmental dysplasia of the hip.

Hepatosplenic alphabeta T cell lymphoma.

A 32-year-old male with chronic hepatitis B was admitted to a hospital with cellulitis in the right leg in September 2006. Pancytopenia, hepatosplenomegaly, and systemic superficial lymph node swelling were noted, and he was referred to our hospital. He developed fever and liver dysfunction in June 2007 and underwent a splenectomy.

Pathway-specific utilization of synaptic zinc in the macaque ventral visual cortical areas.

Synaptic zinc is an activity-related neuromodulator, enriched in hippocampal mossy fibers and a subset of glutamatergic cortical projections, exclusive of thalamocortical or corticothalamic. Some degree of pathway specificity in the utilization of synaptic zinc has been reported in rodents. Here, we use focal injections of the retrograde tracer sodium selenite to identify zinc-positive (Zn+) projection neurons in the monkey ventral visual pathway.

[Early diagnosis and successful treatment of catastrophic antiphospholipid syndrome complicated by multiple organ failure].

A 50-year-old woman was emergently admitted because of rapidly progressive unconsciousness, renal failure, hepatic dysfunction, hemolytic anemia, thrombocytopenia, and high-grade fever in July, 2008. Based on clinical and laboratory findings, we made a tentative diagnosis of thrombotic thrombocytopenic purpura (TTP) and immediately initiated the plasma exchange (PE). Despite the PE, she developed panperitonitis due to multiple intestinal perforation and massive splenic infarction within a week after the admission.

Successful treatment of POEMS syndrome complicated by severe congestive heart failure with thalidomide.

A 55-year-old woman was diagnosed with POEMS syndrome; however, we could not perform high-dose chemotherapy with autologous peripheral blood stem cell transplantation (auto-PBSCT) because of rapidly progressive congestive heart failure. Thus, we treated the patient with thalidomide plus dexamethasone, which brought about a marked improvement of systolic dysfunction, POEMS syndrome-related symptoms and the serum concentrations of vascular endothelial growth factor. Subsequently, we safely performed high-dose chemotherapy with auto-PBCST.

High incidence of thyroid cancer in focal thyroid incidentaloma detected by 18F-fluorodeoxyglucose [corrected] positron emission tomography in relatively young healthy subjects: results of 3-year follow-up.

As 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) is becoming a common imaging modality, the number of thyroid incidentalomas identified by FDG-PET (PET incidentaloma) is increasing. The purpose of this study was to elucidate the risk of cancer in focal thyroid PET incidentaloma in healthy subjects of relatively younger age as well as the usefulness of repeated FDG-PET. The study was conducted with an observation period of three years.

[Successful treatment of chronic disseminated intravascular coagulation syndrome with continuous subcutaneous infusion of heparin using a mobile infusion pump: report of 2 cases].

We report here two patients with chronic disseminated intravascular coagulation (chronic DIC) secondary to aortic aneurysm, who were successfully treated with continuous subcutaneous infusion of heparin. The patients were 69- and 89-year-old males, who were admitted to our hospital because of thrombocytopenia and marked bleeding tendency. The underlying conditions were aortic dissection and aortic aneurysm, respectively.

Laparoscopic unroofing of a large pseudocyst of the spleen: report of a case.

The treatment of splenic cysts remains controversial. A 25-year-old Japanese woman with a 10-cm-long abdominal mass in the left upper quadrant of the abdomen complained of mild, dull pain. A huge splenic cyst was confirmed on computed tomography and magnetic resonance imaging.
