the effects of strontium aluminates of SrAl2O4：Eu2＋,Dy3＋（SAED） and boron-modified SAED （BSAED） phases synthesized from a sol-gel process on thermoluminescence （tL） along with.their afterglow properties were systematically investigated with.thermal activation in the different atmospheres. the result showed th.t the addition of boron and the reduction routes of Eu3＋to Eu2＋ in SrAl2O4：Dy3＋were related to phosphorescent decay properties. the aid of Dy3＋to induce the hole-trapping effect required both SAED and BSAED to be heated at 1300°C under the h2/N2（5%：95%） atmosphere. however, the trapping behavior of the reductions of SAED in nitrogen was similar to the compound without Dy3＋co-doping SrAl2O4：Eu2＋（SAE） in h2/N2（5%：95%）. BSAED showed deeper traps in situ compared to SAED which contained no boron, and this led to the better afterglow properties of BSAED than those of SAED. the afterglow spectrum of BSAED showed two peaks at 400±1 nm and 485±1 nm, which were two individuals composed and contributed from different depths of traps at 0.57 and 0.76eV, accordingly. the depth of the traps was calculated from the hoogenstraaten’s plot of glow curves. the calculations for SAED and SAE were at around 0.43 and 0.18eV, respectively.

Late blight, caused by Ph.tophthora infestans, is one of the most destructive tomato diseases in taiwan. to monitor change in the pathogen’s development, 706 isolates of P. infestans, including 40 isolates from potato, were collected in taiwan from 1991 to 2007. these isolates were analyzed by phenotype and genotype characterization. A dramatic genetic shift occurred in the population of P infestans during taiwan’s 1997-1998 cool growing season. Most isolates obtained after 1998 were non host-specific. Metalaxyl sensitivity of the isolates changed from sensitive/intermediate before 1997 to resistant after 1998. Isolates obtained before 1997 were all US-1 clonal lineage. During the 1997-1998 cool growing season, the US-11 clonal lineage appeared, possibly introduced on table potatoes imported from the USA. the new lineage spread rapidly and since 1999 has almost completely displaced the old population in taiwan. All isolates were of the A1 mating type by pairing with P. parasitica. ten tomato physiological races were identified. A total of 74 sources resistant to race t1,2 were identified from 1783 wild tomato accessions. Among them, accessions L3683, L3684, L3707 and L3708 were confirmed to have durable resistance in multilocation tests. Inheritance studies on CLN657 BCF-274-0-15-4×L3708 and Moneymaker×L3684 indicated the resistance is partially dominant and is inherited as a monogenic trait in both L3708 and L3684. L3708 was used as the donor parent and resistance was introgressed into tomato by backcrossing and selection with a race t1,2 isolate. Six BC3F6 inbred lines, SRE-2037B, C, E, G, h, I and five F populations (FMtt791-795) were selected carrying the Ph-3 gene and exhibited high resistance to race t1,2 with good horticultural traits. Bacterial wilt caused by Ralstonia solanacearum is a devastating disease of tomato production in warm and humid regions worldwide. R. solanacearum is a species complex. All the 158 strains isolated from various host plants in t

以银作参考电极,用钾离子选择电极测定了陶瓷原料中氧化钾的含量。四苯硼钠作滴定剂,它同 K+结合产生沉淀 K[B（C6h5）4]。该反应在 Ph=10的酸度条件下能定量进行。同时 Fe+3、Mg+2、Al+3。以沉淀形式同液相分离,减少了试液的离子强度,有利于滴定。试液中 K+浓度在10-3M—10-2M时可得到准确的结果。滴定剂的稳定性较差,故应经常标定。

the aim of the study was to investigate the effect of black soybean (BS) on the susceptibility of low-density lipoprotein (LDL) in hypercholesterolemic New Zealand wh.te rabbits. Effects of the BS extract (BSE) and its components on monocyte adhesion of human aortic endothelial cells (hAECs), and adhesion molecule were investigated. Rabbits were divided into four groups, including control, 0.5% cholesterol with 20% casein (either with or without 0.5% vitamin E), and BS groups, all fed for 8 weeks. LDL was treated with 10 μM Cu2+ in vitro to determine the LDL lag time, and the vitamin E content of LDL was determined. the thickness of the tunica intima was measured on paraffin sections of thoracic aortas and aortic arches stained with Movat’s pentachrome. hAECs were pretreated with 100 μg/ml of BSE, and 10 μM of genistein, daidzein, cyanidin, and aspirin for 18 h, followed by tumor necrosis factor (tNF)-α (2 ng/ml) for 6 h, after which U937 cell adhesion was determined. Adhesion molecule expression was examined using ELISAs. the LDL lag time in the BS group was similar to th.t in the vitamin E group, while its lag time was significantly longer than those in the control and casein groups. the ratio of the intimal area/medial area of the aortic arch of the casein group was significantly higher than those in the control, BS, and vitamin E groups. the vitamin E group had the lowest value, and was closest to the control group. the BS group exhibited a significantly decreased atheroma region in the aortic arch compared to the casein group. Pre-incubation with BSE, genistein, daidzein, cyanidin, and aspirin significantly decreased adhesion by U937 monocytic cells to tNF-α stimulated hAECs. Genistein, daidzein, cyanidin, and aspirin significantly suppressed the expression of vascular cell adhesion molecule (VCAM)-1. Only genistein and aspirin significantly decreased intracellular adhesion molecule (ICAM)-1 expression compared to tNF-α treatment, while no treatments had any ef

Pancreatic cancer is highly lethal. Current research.th.t combines radiation with.targeted therapy may dramatically improve prognosis. Cancerous cells are characterized by unstable genomes and activation of DNA repair pathways, which are indicated by increased phosphorylation of numerous factors, including h2 AX, AtM, AtR, Chk1, Chk2, DNA-PKcs, Rad51, and Ku70/Ku80 h.terodimers. Radiotherapy causes DNA damage. Cancer cells can be made more sensitive to the effects of radiation(radiosensitization) through inhibition of DNA repair pathways. the synergistic effects, of two or more combined non-lethal treatments, led to coadministration of chemotherapy and radiosensitization in BRCA-defective cells and patients, with promising results. AtM/Chk2 and AtR/Chk1 pathways are principal regulators of cell cycle arrest, following DNA doublestrand or single-strand breaks. DNA double-stranded breaks activate DNA-dependent protein kinase, catalytic subunit(DNA-PKcs). It forms a holoenzyme with Ku70/Ku80 h.terodimers, called DNA-PK, which catalyzes the joining of nonhomologous ends. this is the primary repair pathway utilized in human cells after exposure to ionizing radiation. Radiosensitization, induced by inhibitors of AtM, AtR, Chk1, Chk2, Wee1, PP2 A, or DNA-PK, has been demonstrated in preclinical pancreatic cancer studies. Clinical trials are underway. Development of agents th.t inhibit DNA repair pathways to be clinically used in combination with radiotherapy is warranted for the treatment of pancreatic cancer.

人工色素双分子类脂膜(PBLM)厚度小于100(?),分开两个含不同氧化还原物的水溶液。我们的实验用卟啉类色素BLM,在照光时可将此PBLM看作是有两个界面的有机半导体,一侧是p-型的光阴极,另一侧为n-型的光阳极。光生电荷(电子和空穴)可跨越界面而迁移,导至膜的一边发生还原作用,另一边发生氧化作用。已证实色素BLM可将光能转换为电能或化学能,或许在将来可将色素BLM用于太阳能的转换装置。
