A diagnosis program of damage-symptom caused by fruit tree pest was developed using Portable Document Format (Docucom PDF). To construct program structure, the damage patterns of plants cased by pests and the morphological rhararteristics of pests were sorted by plant organs. Diagnoses are rallied out by selecting a host species > document symptoms arranged by plant organs > comparing similar symptoms of pests using step by step menu through damage symptoms. In addition, pest information can be accessed either through the scientific or common name of the pest organism.
Evaluation of the prognostic significances of γ-secretase genes in pancreatic cancer

<P>With the growing requirement for novel prognostic biomarkers for pancreatic cancer, many studies have focused on clinical and/or genomic variables. Although many studies have been performed, carbohydrate antigen 19-9 is the only biomarker in clinical use. Therefore, the present study examined whether γ-secretase genes, including presenilin (<I>PSEN</I>), nicastrin (<I>NCSTN</I>), presenilin enhancer protein 2 (<I>PSENEN</I>), and anterior pharynx-defective 1 (<I>APH1</I>-), could serve as prognostic factors for pancreatic cancer. The cohorts selected included >100 pancreatic cancer patients. Patient data were downloaded from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GSE21501). The prognostic roles of the γ-secretase genes were analyzed by several survival analysis methods. Among the γ-secretase genes, the prognosis tended to be worse in the 2 cohorts with increasing expression of <I>PSEN1, APH1A</I>, and <I>PSENEN</I>, while the remaining genes were the opposite in the 2 cohorts. Notably, although the patient characteristics were quite different, <I>APH1A</I> was statistically significantly associated with prognosis in the 2 cohorts. The hazard ratio of <I>APH1A</I> for overall survival was 1.598 (TCGA) and 2.724 (GSE21501). These results contribute to the study of γ-secretase in pancreatic cancer. We believe that γ-secretase, particularly <I>APH1A</I>, will be a new prognostic biomarker for pancreatic cancer.</P>

Novel new red-light emitting perylene fluoroionophore N,N'-dipropyl-1,7-bis(calix[4]azacrown-5-crown-5)- 3,4,9,10-perylene tetracarboxy diimide (3) was prepared by reacting N,N'-dipropyl-1,7-dibromo-3,4,9,10- perylene tetracarboxy diimide (1) with calix[4]azacrown-5-crown-5. Also the alternating copolymer (4) with similar repeating unit was prepared reacting by calix[4]bisazacrown-5 with 1. Metal ion binding by 3 and 4 leads to a blue-shift of absorption band and emission spectra. When ionophoric characteristics were investigated by binding alkali, alkali earth metal and various metal ions, polymeric ionophores displayed large fluorescence decreasing effects with K+, Ag+ and Ba2+, which was rationalized by photo-induced charge transfer (PCT).

Preoperative assessment of electrocardiographical(EKG) abnormalities in the patients with subarachnoid hemorrhage(SAH) is important. Authors analyzed 58 SAH patients who had EKG abnormalities of neurogenic origin. EKG abnormalities consisted of T wave abnormality, arrhythmia. ST segment change. QT prolongation and U wave. Five patients were dead in this study because of brain swelling(3cases) and cerebral spasm(2 cases). EKG abnormalities were normalized 13 days after aneurysmal SAH. Radioactive nuclear(^(99m)Tc-pyrophosphate) scan of myocardial revealed normal findings in the patients with EKG abnormalities of neurogenic origin. It is concluded that life-saving surgical intervention need not be delayed in the patients with EKG abnormalities of neurogenic origin. On the other hand, patients who had cardiac origin EKG abnormalities need a careful and detailed preanesthetic cardiac evaluation.
Occurrence of Pasteuria spp. Associated with Plant-parasitic Nematodes in Korea

A survey was conducted on the occurrence of Pasteuria spp. associated with plant-parasitic nematodes in greenhouse and open field soils in Korea from 1996 to 2000. Among the 372 soil samples assayed, 20 samples had plant-parasitic nematodes attached with Pasteuria spp. endospores. The nematodes found with Pasteuria endospores and their collection sites were Meloidogyne spp. in Sungju, Cheju, and Yeoju and Helicotylenchus sp., Pratylenchus sp., Heterodera sp., and Aphelenchus sp. in Cheju. Morphological characteristics of the endospores on Meloidogyne incognita juveniles observed under light, scanning and transmission electron microscopes were same as the previous description of Pasteuria penetrans Sayre & Starr 1988.
