[Localized Nodular Pulmonary Amyloidosis after Resection of Lung Cancer;Report of a Case].

A 79-year-old man had undergone endoscopic colorectal resection for colon cancer and partial resection of right S2 for lung cancer in 2007. Two years later, enlargement of a small nodule in the right S10 detected by chest computed tomography was noted. Partial lung resection was performed in April 2009, and the pathological diagnosis was localized nodular pulmonary amyloidosis.

Rare Pulmonary Metastasis From Thyroid Mucosa-Associated Lymphoid Tissue Lymphoma.

Primary pulmonary lymphomas constitute up to 1% of all pulmonary malignancies. Patients with mucosa-associated lymphoid tissue (MALT) lymphoma represent approximately 90% of patients with primary pulmonary lymphoma. Most pulmonary MALT lymphomas are primary tumors.

Degradation of the persistent organic pollutant [14C]heptachlor in Japanese field soils.

The fate of [(14)C]heptachlor in Saitama soil and the degradation of [(14)C]heptachlor in four Japanese field soils over 112 d after application were investigated. Heptachlor was degraded mainly to cis-heptachlor epoxide by a biotic process and to 1-hydroxychlordene by an abiotic process in the field soils. Volatilization of heptachlor and cis-heptachlor epoxide from the soil was observed over the experimental period.

A case of primary combined neuroendocrine carcinoma with squamous cell carcinoma in the upper gingiva.

Neuroendocrine carcinoma is a rare neoplasm that occurs widely in various organs and tissues. The biological behavior of this tumor in the oral region remains poorly understood. We encountered an extremely rare case of combined neuroendocrine carcinoma with squamous cell carcinoma, occurring at the buccal gingiva in a 62-year-old woman.

Bioaccumulation and metabolism of [14C]bisphenol A in the brackish water bivalve Corbicula japonica.

The brackish water bivalve mollusk Corbicula japonica was exposed to brackish water containing approximately 9 microg/l [(14)C]bisphenol A (BPA) for 168 h (the uptake phase), and subsequently transferred to clean brackish water for 144 h (the depuration phase) under semi-static conditions. Mono and disulfate conjugates of BPA were detected in the bivalves as major metabolites. At the end of the uptake phase, the visceral mass contained the highest (14)C-concentration, and the monosulfate conjugate of BPA was a major metabolite in the visceral mass.

Identification of Curcuma plants and curcumin content level by DNA polymorphisms in the trnS-trnfM intergenic spacer in chloroplast DNA.

With the goal of developing an accurate plant identification method, molecular analysis based on polymorphisms of the nucleotide sequence of chloroplast DNA (cpDNA) was performed in order to distinguish four Curcuma species: C. longa, C. aromatica, C.

Differences in concentrations of acetyl-CoA and malonyl-CoA in shoots and roots of Zea mays.

We measured the concentrations of acetyl-CoA and malonyl-CoA in shoots and roots of corn (Zea mays, L., cv. "Peter Corn").

Determination of acetyl-CoA and malonyl-CoA in germinating rice seeds using the LC-MS/MS technique.

A highly sensitive and selective analytical method was developed to determine levels of acetyl-CoA and malonyl-CoA in plant tissues. The analytical method includes a convenient extraction method for plant samples and a new LC-MS/MS technique utilizing an ion pair reagent. These acyl-CoAs, present in germinating rice seeds, were then determined by the method developed.
