Development of Liquid-Chromatography Tandem-Mass-Spectrometry Method for Determining Environmental Contamination by Powdered Medicinal Drugs in Pharmacies.

The environment and personnel are both exposed to powdered pharmaceuticals inside pharmacies. This makes developing new methods for rapidly determining such contaminants an important objective. In this study, we developed a liquid-chromatography tandem-mass-spectrometry (LC-MS/MS) method for the simultaneous qualitative and quantitative determination of powdered medicinal drugs, such as famotidine, risperidone, lansoprazole, olanzapine, haloperidol, clarithromycin, promethazine, levomepromazine, and chlorpromazine.

[Systemic lupus erythematosus with marked eosinophilia and clinical features mimicking TAFRO syndrome].

A 76-year-old woman was referred to our hospital because of fever, hemorrhagic skin lesion with pruritus, and severe thrombocytopenia. Anemia; marked eosinophilia; and elevated ALP, CRP, and soluble IL-2 receptor levels were observed on admission. Both anti-nuclear antibody and Coombs tests were positive.

[Neutrophil recovery by eltrombopag treatment in a patient with adult-onset autoimmune neutropenia and immune thrombocytopenia].

Adult-onset autoimmune neutropenia (AIN) is rarely self-limiting, unlike infant-onset AIN. Although several therapeutic agents have been reported, including corticosteroids, more effective treatment options may exist. Here, we describe neutrophil recovery by eltrombopag in a 52-year-old male AIN patient with immune thrombocytopenia (ITP) who was referred to our hospital with severe neutropenia.

[Idiopathic thrombocytopenic purpura during chemotherapy for liver metastasis of rectal cancer].

Unlabelled: Neoadjuavnt chemotherapy for liver metastasis of colorectal cancer implies issues about timing for resection and management for adverse events due to chemotherapy.

Case: A 50-year-old male patient with synchronous liver metastasis from rectal cancer had a surgery for primary lesion followed by neo-adjuvant chemotherapy for liver resection. Chemotherapy of bevacizumab + mFOLFOX6 achieved a partial response for liver metastasis.

Complement C1q regulates LPS-induced cytokine production in bone marrow-derived dendritic cells.

We show here that C1q suppresses IL-12p40 production in LPS-stimulated murine bone marrow-derived dendritic cells (BMDC). Serum IL-12p40 concentration of C1q-deficient mice was higher than that of wild-type mice after intraperitoneal LPS-injection. Because neither globular head of C1q (gC1q) nor collagen-like region of C1q (cC1q) failed to suppress LPS-induced IL-12p40 production, both gC1q and cC1q, and/or some specialized conformation of native C1q may be required for the inhibition.

Antiviral activity of limitin against encephalomyocarditis virus, herpes simplex virus, and mouse hepatitis virus: diverse requirements by limitin and alpha interferon for interferon regulatory factor 1.

Limitin has sequence homology with alpha interferon (IFN-alpha) and IFN-beta and utilizes the IFN-alpha/beta receptor. However, it has no influence on the proliferation of normal myeloid and erythroid progenitors. In this study, we show that limitin has antiviral activity in vitro as well as in vivo.

T lymphocytes constitutively produce an interferonlike cytokine limitin characterized as a heat- and acid-stable and heparin-binding glycoprotein.

Several reports have described "multifunctional" eukaryotic mRNAs producing more than one protein through alternative translational initiation at multiple AUG codons. There are 2 such codons in the 5' region of our recently cloned limitin gene where 2 open reading frames overlap by 34 nucleotides. The deduced protein translated from the first ATG contains 33 amino acids, lacks a signal peptide, and has no obvious effects on the transfected 293T cells.
