Synthesis of 4,4-Disubstituted 3,4-Dihydropyrimidin-2(1H)-ones and -thiones, the Corresponding Products of Biginelli Reaction Using Ketone, and Their Antiproliferative Effect on HL-60 Cells.

An efficient synthetic method for novel 4,4-disubstituted 3,4-dihydropyrimidin-2(1H)-ones 5 and -thiones 6 was developed. The cyclocondensation reaction of O-methylisourea hemisulfate salt 11 with 8 gives a tautomeric mixture of dihydropyrimidines 12 and 13 following acidic hydrolysis of the cyclized products to produce 5 in high yields. Thionation reaction of 5 at the 2-position smoothly proceeds to give 2-thioxo derivatives 6.

Skin Necrosis Due to the Extravasation of Irritant Anticancer Agents.

A 70-year-old man with malignant lymphoma was subjected to a fourth course of chemotherapy using gemcitabine and cisplatin. During the intravenous infusion of anticancer agents, pain and redness was observed at the site of insertion. The patient was subsequently treated with the strongest topical steroids and topical cooling agents.

Rosehip inhibits xanthine oxidase activity and reduces serum urate levels in a mouse model of hyperuricemia.

Rosehip, the fruit of L., has traditionally been used to treat urate metabolism disorders; however, its effects on such disorders have not been characterized in detail. Therefore, the present study investigated the effects of hot water, ethanol and ethyl acetate extracts of rosehip on xanthine oxidase (XO) activity .

Typing of Melissococcus plutonius isolated from European and Japanese honeybees suggests spread of sequence types across borders and between different Apis species.

Melissococcus plutonius is an important pathogen of honeybee larvae and causes European foulbrood (EFB) not only in European honeybees (Apis mellifera) but also in other native honeybees. We recently confirmed the first EFB case in Japanese native honeybees (Apis cerana japonica) and isolated M. plutonius from this case.

Perineural xanthoma associated with type 2 diabetes mellitus and hyperlipidemia.

It is well known that patients with diabetes mellitus (DM) may demonstrate skin manifestations, or dermadromes, due to disease-related metabolic, vascular, neurologic, and/or immunologic disturbances; however, the pathogenesis of some of these manifestations remains unknown. Xanthomas often are associated with increased levels of serum cholesterol and/or triglycerides and therefore can present as a dermadrome in patients with a history of uncontrolled DM and hyperlipidemia. The presence of tender lesions in this patient population can indicate a diagnosis of perineural xanthoma.

Development of duplex PCR assay for detection and differentiation of typical and atypical Melissococcus plutonius strains.

Melissococcus plutonius is the causative agent of an important honeybee disease, European foulbrood (EFB). In addition to M. plutonius strains with typical characteristics (typical M.

IgA pemphigus with non-pustular erythematous lesions and IgA antibodies to desmocollins 1 and 2.

IgA pemphigus is a rare variant of pemphigus. IgA pemphigus is subdivided into intraepidermal neutrophilic IgA dermatosis-type (IEN-type), whose target antigen is still an enigma, and subcorneal pustular dermatosis-type, whose target antigen is desmocollin 1 (Dsc1). We report a 56-year-old Japanese male with IgA pemphigus showing atypical erythema.

Identification of mutations involved in the requirement of potassium for growth of typical Melissococcus plutonius strains.

Melissococcus plutonius is a fastidious honeybee pathogen, and the addition of KH(2)PO(4) to culture medium is required for its growth. Using genome sequences and a newly developed vector, we showed that mutations in genes encoding Na(+)/H(+) antiporter and cation-transporting ATPase are involved in the potassium requirement for growth.

Isolated adrenocorticotropin deficiency associated with delirium and takotsubo cardiomyopathy.

We report a 65-year-old woman with isolated adrenocorticotropic hormone (ACTH) deficiency. The patient was transported to the emergency outpatient department by ambulance complaining of malaise and nausea. Because her laboratory data revealed hyponatremia, we performed endocrinological examinations and diagnosed isolated ACTH deficiency.

Complete genome sequence of Melissococcus plutonius DAT561, a strain that shows an unusual growth profile and is representative of an endemic cluster in Japan.

We report the complete genome sequence of Melissococcus plutonius DAT561, which is a causative agent of European foulbrood. M. plutonius DAT561 is a representative of nonfastidious strains isolated in Japan.

Diversity of Melissococcus plutonius from honeybee larvae in Japan and experimental reproduction of European foulbrood with cultured atypical isolates.

European foulbrood (EFB) is an important infectious disease of honeybee larvae, but its pathogenic mechanisms are still poorly understood. The causative agent, Melissococcus plutonius, is a fastidious organism, and microaerophilic to anaerobic conditions and the addition of potassium phosphate to culture media are required for growth. Although M.

Complete genome sequence of Melissococcus plutonius ATCC 35311.

We report the first completely annotated genome sequence of Melissococcus plutonius ATCC 35311. M. plutonius is a one-genus, one-species bacterium and the etiological agent of European foulbrood of the honeybee.

Postnatal development of the mouse volatile papilla taste bud cells.

In the present study, we examined specific markers for taste bud cells in the mouse and the postnatal development of volatile papilla taste bud cells in ddY mice. We examined the immunoreactivity of 4 types of carbonic anhydrase isoenzymes, CA I, CA II, CA III and CA VI, as specific markers for taste bud cells, and K8.13 cytokeratin antibody as a specific marker for the lingual epithelial cells.
