Pulmonary Tumor Thrombotic Microangiopathy Due to Gastric Cancer Diagnosed Antemortem by a Cytological Examination of Aspirated Pulmonary Artery Blood.

A 66-year-old Japanese man receiving systemic chemotherapy for advanced gastric cancer presented with exertional dyspnea. D-dimer was elevated in the blood. Echocardiography revealed pulmonary hypertension, and a ventilation-perfusion scan indicated decreased perfusion in the bilateral lungs.

Discovery of highly selective κ-opioid receptor agonists: 10α-Hydroxy TRK-820 derivatives.

κ-Opioid receptor agonists with high selectivity over the μ-opioid receptor are attractive targets in the development of drugs for pain and pruritus. We previously reported the synthesis of 10α-hydroxy TRK-820 (1). In this study, we elucidated the biological properties of 1 and optimized its 6-acyl unit by modifying our synthetic route.

Clinical significance of co-expression of MYC and BCL2 protein in aggressive B-cell lymphomas treated with a second line immunochemotherapy.

The clinical significance of concurrent expression of MYC and BCL2 protein, known as "double-expressor lymphoma" (DEL), among patients with relapsed or refractory aggressive B-cell lymphomas, remains unclear. A retrospective analysis was performed of 38 patients treated with a salvage treatment consisting of rituximab, ifosfamide, etoposide, cytarabine and dexamethasone followed by consolidative high-dose chemotherapies. A total of 17 cases (45%) were categorized as DEL using immunohistochemical assay with a cut-off value of positivity of 40% for MYC and 50% for BCL2, respectively.

Discovery of potent α1L-adrenoceptor agonists: Design and synthesis of bicyclic derivatives.

We aimed to create a novel and potent α(1L)-adrenoceptor agonist because such agonists are possible drug candidates for stress urinary incontinence. We used ligand-based drug design and evaluated the α(1L)-adrenoceptor agonist activity of the designed compounds. Among them, tetrahydroquinoline derivative 50 showed the most potent activity (ratio of noradrenaline half maximal effective concentration, 0.

Dose-intensified CHOP with rituximab (R-Double-CHOP) followed by consolidation high-dose chemotherapies for patients with advanced diffuse large B-cell lymphoma.

Even after the advent of rituximab, clinical outcomes of conventional immuno-chemotherapy for high-risk diffuse large B-cell lymphoma (DLBCL) remain unsatisfactory. We retrospectively evaluated the efficacy and safety of R-Double-CHOP (R-D-CHOP), consisting of rituximab (375 mg/m(2), day -2), cyclophosphamide (750 mg/m(2), day 1, 2), doxorubicin (50 mg/m(2), day 1, 2), vincristine [1.4 mg/m(2) (maximum 2.

HIS-388, a novel orally active and long-acting 11β-hydroxysteroid dehydrogenase type 1 inhibitor, ameliorates insulin sensitivity and glucose intolerance in diet-induced obesity and nongenetic type 2 diabetic murine models.

11β-Hydroxysteroid dehydrogenase type 1 (11β-HSD1) is considered a potential therapeutic target in the treatment of type 2 diabetes mellitus. In this study, we investigated the pharmacological properties of HIS-388 (N-[(1R,2s,3S,5s,7s)-5-hydroxyadamantan-2-yl]-3-(pyridin-2-yl) isoxazole-4-carboxamide), a newly synthesized 11β-HSD1 inhibitor, using several mouse models. In cortisone pellet-implanted mice in which hypercortisolism and hyperinsulinemia occur, single administration of HIS-388 exhibited potent and prolonged suppression of plasma cortisol and lowered plasma insulin levels.

Discovery of 1-oxa-4,9-diazaspiro[5.5]undecane-based trisubstituted urea derivatives as highly potent soluble epoxide hydrolase inhibitors and orally active drug candidates for treating of chronic kidney diseases.

We identified 1-oxa-4,9-diazaspiro[5.5]undecane-based trisubstituted ureas as highly potent soluble epoxide hydrolase (sEH) inhibitors and orally active agents for treating chronic kidney diseases. Compound 19 exhibited excellent sEH inhibitory activity and bioavailability.

Discovery of 2,8-diazaspiro[4.5]decane-based trisubstituted urea derivatives as highly potent soluble epoxide hydrolase inhibitors and orally active drug candidates for treating hypertension.

We identified 2,8-diazaspiro[4.5]decane-based trisubstituted urea derivatives as highly potent soluble epoxide hydrolase (sEH) inhibitors and orally active agents for treating hypertension. Docking studies using human and murine sEH X-ray crystal structures revealed steric hindrance around the side chain of Phe406 of murine sEH.

A rare case of propofol-induced liver injury during modified electroconvulsive therapy in an elderly woman.

A 75-year-old woman developed depression in 2010 and was treated with oral medications at our Department of Psychiatry. Since she showed no tendency toward improvement, she underwent modified electroconvulsive therapy (mECT). Later, she developed severe liver injury that was presumably induced by the propofol used for mECT.

Efficacy of a dose-intensified CHOP (Double-CHOP) regimen for peripheral T-cell lymphomas.

Peripheral T-cell lymphomas (PTCLs) are a rare and heterogeneous group of non-Hodgkin lymphomas, often resulting in poor prognoses. The CHOP chemotherapy regimen, which includes cyclophosphamide, doxorubicin, vincristine and prednisone, has been used previously to treat other types of lymphomas. Here, we examined the efficacy and safety of a dose-intensified CHOP regimen (Double-CHOP), which was followed by autologous stem-cell transplantation (ASCT) or high-dose methotrexate (HDMTX), in PTCL patients.

A case series of Bacillus cereus septicemia in patients with hematological disease.

Objective: Bacillus cereus (B. cereus) septicemia is a cause of life-threatening infection in patients with hematologic diseases. However, preventing a fatal prognosis in patients with B.

Long-term follow-up of localized, primary gastric diffuse large B-cell lymphoma treated with rituximab and CHOP.

The addition of rituximab to cyclophosphamide, doxorubicin, vincristine and prednisone [CHOP (i.e., R-CHOP)] is considered to be the standard regimen for treating localized, primary gastric diffuse large B-cell lymphoma (PG-DLBCL).

An effective salvage treatment using ifosfamide, etoposide, cytarabine, dexamethasone, and rituximab (R-IVAD) for patients with relapsed or refractory aggressive B-cell lymphoma.

We evaluated the efficacy and toxicity of a new salvage regimen, consisting of rituximab (375 mg/m(2), day 1), ifosfamide (1500 mg/m(2) on days 3-7), etoposide (150 mg/m(2), days 3-5), cytarabine (100 mg/m(2), days 3-5) and dexamethasone (40 mg/body, days 3-5) (R-IVAD) for relapsed or refractory aggressive B-cell lymphoma. In this study, a total of 32 patients with a median age of 64 years (range 38-79) who received an average of 2.6 cycles of R-IVAD from 2001 to 2009 in our institution were retrospectively analyzed.
