BACKGROUND: Rituximab is effective against complicated childhood steroid-dependent nephrotic syndrome (SDNS). Peripheral blood B-lymphocyte (B-cell) depletion is strongly correlated with persistent remission, relapse rarely occurring during B-cell depletion; however, we have encountered several such patients. METHODS: We retrospectively analyzed the characteristics and clinical course of 82 patients with SDNS treated with rituximab from January 2007 to December 2012 in our institution...

Elderly/comorbid patients with chronic lymphocytic leukemia (CLL) require low-toxicity treatments. Internationally, the standard treatment for such patients is chlorambucil and an anti-CD20 therapy; however, chlorambucil is not approved in Japan. The aim of the present study was to evaluate the safety, efficacy and pharmacokinetics of ofatumumab in combination with chlorambucil in Japanese patients with previously untreated CLL who were inappropriate for fludarabine-based therapy. Ten patients were enrolled and treated in this study, all of whom received at least one dose of the study drugs...

Salivary duct carcinoma (SDC) is a high-grade malignant salivary gland tumor associated with poor prognosis, frequent recurrence, and metastasis. An 82-year-old man presented at the department of oral and maxillofacial surgery at Tokai University Hospital with a painless swelling in the right submandibular region that had been there for 20 years. On presentation, an elastic hard tumor, 50 × 50 mm in size, was observed in the submandibular region. Diagnostic imaging was performed, and a malignant tumor in the submandibular gland was suspected...

In June 2015, a highly fatal and acute disease broke out in a duckling farm in Hyogo Prefecture, Japan. The birds exhibited poor growth, reduced movement, lying in a dorsal recumbent position, depression, lethargy, ataxia and opisthotonus, with a high mortality rate of approximately 76%. By performing a reverse transcription-polymerase chain reaction (RT-PCR) using primers specific for duck hepatitis A virus type 1 (DHAV-1), we obtained the PCR products of a predicted size. The nucleotide sequences of the PCR products showed a >96% identity with that of the DHAV-1, HB02 strain, which was isolated in China...

The first binary cell fate decision occurs at the morula stage and gives rise to two distinct types of cells that constitute the trophectoderm (TE) and inner cell mass (ICM). The cell fate determinant, Cdx2, is induced in TE cells and plays an essential role in their differentiation and maintenance. Notch and Hippo signaling cascades are assumed to converge onto regulatory elements of Cdx2, however, the underlying molecular mechanisms are largely unknown. Here, we show involvement of Strawberry Notch1 (Sbno1), a novel chromatin factor of the helicase superfamily 2, during preimplantation development...

Spermatogenesis is a complicated process that originates from spermatogonial stem cells (SSCs), which have self-renewal activity. Because SSCs are the only stem cells in the body that transmit genetic information to the next generation, they are an attractive target for germline modification. Although several virus vectors have been successfully used to transduce SSCs, cell toxicity or insertional mutagenesis of the transgene has limited their usage. Adeno-associated virus (AAV) is unique among virus vectors because of its target specificity and low toxicity in somatic cells, and clinical trials have shown that it has promise for gene therapy...

PURPOSE: When treating large metastatic brain tumors with stereotactic radiotherapy (SRT), high dose conformity to target is difficult to achieve. Employing a modified planning target volume (mPTV) instead of the original PTV may be one way to improve the dose distribution in linear accelerator-based SRT using a dynamic conformal technique. In this study, we quantitatively analyzed the impact of a mPTV on dose distribution. MATERIALS AND METHODS: Twenty-four tumors with a maximum diameter of >2 cm were collected...

BACKGROUND: Severe anaphylactic symptoms can occur during oral food challenges (OFCs). Thus, high-risk patients (e.g., patients with a history of anaphylaxis or high antigen-specific immunoglobulin E [IgE] levels) must carefully undergo OFCs in hospitals. We attempted to identify the risk factors for severe symptoms during OFC testing among high-risk patients. METHODS: We retrospectively evaluated patients' characteristics and severe symptoms that were experienced during a double-blind placebo-controlled food challenge test performed before the patients underwent oral immunotherapy between June 2008 and June 2012...

Only free drugs have been believed to be carried into tissues through active or passive transport. However, considering that lipoproteins function as carriers of serum lipids such as cholesterol and triglycerides, we hypothesized that lipoproteins can associate with certain drugs and mediate their transport into tissues in lipid-associated form. Here, in vitro and in vivo studies with low density lipoprotein receptor (LDLR)-overexpressing or -knockdown cells and wild-type or LDLR-mutant mice were used to show the association of various drugs with lipoproteins and the uptake of lipoprotein-associated drugs through a lipoprotein receptor-mediated process...

Experimental animal models have played an indispensable role in the development of human induced pluripotent stem cell (iPSC) research. The derivation of high-quality (so-called "true naïve state") iPSCs of non-human primates enhances their application and safety for human regenerative medicine. Although several attempts have been made to convert human and non-human primate PSCs into a truly naïve state, it is unclear which evaluation methods can discriminate them as being truly naïve. Here we attempted to derive naïve cynomolgus monkey (Cm) (Macaca fascicularis) embryonic stem cells (ESCs) and iPSCs...
