Acid sulfate soils, peat soils, sandy podzolic, and saline soils are widely distributed in Peninsular Thailand. Native plants adapted to such problem soils have grown well, and showed no symptom of mineral deficiency or toxicity. Dominant plants growing in low pH soils (acid sulfate and peat) were Melastoma marabathricum and Melaleuca cajuputi. Since M.(More)
The P-N regression coefficient was moderate in Magnoliales, Coniferopsidae, Pteridophyta, and Asterids, but very high in Caryophyllids, and very low in Rosids. The K-N regression coefficient in trees remained constant regardless of evolution, and that in grasses was high except for Rosids compared with that in trees. The coefficient was very high in(More)
Pancreatic ductal adenocarcinoma (PDAC) is difficult to distinguish from autoimmune pancreatitis (AIP) because of their clinical and radiological similarities, and therefore simple and minimally invasive surrogate markers for differential diagnosis would be useful. In our previous studies, we identified four microRNAs (miRNAs)-miR-7, miR-34a, miR-181d, and(More)
The objective of this research was to analyze selected minerals in leaves of plants, belonging to 166 species growing in alluvial, low pH, brown forest and serpentine soils. Mineral characteristics of the soils involved were also determined. For the macronutrients, in trees grown in alluvial soil, N, P, Ca, and Mg concentrations of leaves were higher in(More)
An absolute quantification method for the N-myc gene copy number of neuroblastoma specimens was established by applying the competitive polymerase chain reaction (cPCR). The competitor plasmid (pZH2) lacking an MluI site in the exon 2 was constructed to distinguish two product species amplified from genomic DNA and the competitor plasmid. By using this cPCR(More)
Acid sulfate, peat, sandy podzolic, and saline soils are widely distributed in the lowlands of Thailand and Malaysia. The nutrient concentrations in the leaves of plants grown in these type of soils were studied with the aim of developing a nutritional strategy for adapting to such problem soils. In sago and oil palms that were well-adapted to peat soil,(More)
We report a case of pancreatic intraepithelial neoplasia-3 (PanIN-3) with autoimmune pancreatitis (AIP). The patient, a 75-year-old man, had been diagnosed to have AIP with stenosis of the main pancreatic duct. After six years, computed tomography demonstrated dilatation of the main pancreatic duct in the mid-pancreas. Although we could not confirm the(More)
