Expression and significance of c-IAP2 and GAS1 in Hodgkin's lymphoma and anaplastic large cell lymphoma

AIM: To detect the expression of cytoplasmic inhibitor of apoptosis protein 2 (c-IAP2) and growth arrest-specific gene 1 (GAS1) in Hodgkin's lymphoma (HL) and anaplastic large cell lymphoma (ALCL) and to investigate the role of two genes in the pathogenesis of HL and ALCL.METHODS: HE staining, the antibodies CD30, CD15, CD45RO and CD20 were used to screen the cases of HL and ALCL from 288 cases of lymphoma. The clarified HL and ALCL were subjected for immunohistochemical staining by SP and ABC methods to analyze the expression of c-IAP2 and GAS1. RESULTS: ①The positive rate of c-IAP2 in HL was 25/26(96.1%) while that in ALCL was 6/19(31.6%), there presented statistic significance between HL and ALCL groups(P<0.05), meanwhile the positive rate of GAS1 showed statistic significance between HL and ALCL groups(P<0.05). ②Two cases were showed to be a mixed type combined with large tumor cells of HL and relatively smaller tumor cells of ALCL.CONCLUSION: ①The different expression of c-IAP2 and GAS1 in HL and ALCL implied a different mechanism of oncogenesis and the different defects in the pathway of signal transduction of apoptosis in HL and ALCL;②Few cases showed an overlap and a likely transitional state between HL and ALCL; ③The different expressing manner of GAS1 and c-IAP2 in HL and ALCL implied the potential marks for the differential dignosis of two kinds of lymphoma.     

Fruit nutrient content and lipoxygenase activity in relation to the production of malformed and button berries in strawberry (Fragaria × ananassa Duch.)

Fruit nutrient content and lipoxygenase (LOX) activity were determined in strawberry fruit to establish a relationship, if it exists, between nutrients, and LOX activity with the fruit malformation and nubbins or button berry disorders. Nearly 17% fruit were affected by malformation and 10% by nubbins in open-field-grown strawberries. ‘Etna’ produced higher proportion of malformed (22.7%) as well as button berries (16.9%) and ‘Sweet Charlie’ the lowest (8.9% and 3.3%, respectively). Dry matter content (%) was lower in malformed (5.2%) and button berries (3.23%) than normal berries (7.41%). The concentration of P and Mg did not differ significantly, but that of N and K was notably higher and of Ca and B was lower in malformed and button berries than normal berries. Consequently, the N/Ca and K/Ca ratios were higher in malformed and button berries. LOX activity was significantly higher in malformed as well as button berries than normal berries, with significant differences among cultivars. The correlations between N, K and malformed and button berries were positive and between Ca and B, and malformed and button berries were negative. Similarly, the correlation between LOX activity and malformed, and button berries were also positive, indicating that excess of N and K, and deficiency of Ca and B are related to the production of malformed and buttons or nubbins in strawberry.     

Effects of macro and micro-environmental factors on the species richness of terrestrial tardigrade assemblages in an Iberian mountain environment

Tardigrade communities are affected by micro and macro-environmental conditions but only micro-environmental variables, and altitudinal gradients have been studied. We review previous reports of altitudinal effects and evaluate the influence by interacting macro- (climate, soils, biome, and others) and micro-environmental (vegetation, moss and leaf litter) factors on tardigrade assemblages at the Sierra de Guadarrama mountain range (Iberian Central System Mountains, Spain). Terrestrial tardigrade assemblages were sampled using standard cores to collect leaf litter and mosses growing on rocks. General Linear Models were used to examine relationships between Tardigrada species richness and abundance, and macro- and micro-environmental variables (altitude, habitat characteristics, local habitat structure and dominant leaf litter type, and two bioclimatic classifications). Variation partitioning techniques were used to separate the effects of altitude and habitat variation, and to quantify the independent influences of climate and soil, vegetation structure and dominant type of leaf litter. Altitude shows a unimodal relationship with tardigrade species richness, although its effect independent of habitat variation is negligible. The best predictors for species richness were bioclimatic classifications. Separate and combined effects of macro-environmental gradients (soil and climate), vegetation structure and leaf litter type are important determinants of richness. A model including both macro- and micro-environmental variables explained nearly 60% of tardigrade species richness in micro-scale plots. Abundance was significantly related only to soil composition and leaf litter type. Tardigrade abundance was not explained by macro-environmental gradients analysed here, despite a significant correlation between abundance and richness.

Effect of Jinan injection on ultrastructure of lung cancer cell lines

AIM: To investigate the effects of Chinese medicine, Jinan injection, on ultrastructure and mitochondria in cultured lung cancer cell lines. METHODS: The cultured lung cancer cell lines PG and PAa were used and divided into 4 groups: control (C), cisplatin (DDP), Jinan (JA) and Jinan in combination with cisplatin (DJ), respectively. The changes of morphology and mitochondria membrane potential, intracellular Ca²⁺ and pH in every group were observed by inverted microscope and electronic microscope as well as by using flow cytometry, staining by rhodamine, Fluo-3 and BCECF, respectively. RESULTS: Degeneration cells showed chromatin condensation and peripheral congregation. In cytoplasm autophage lysosome increased and myelinoid body was seen easily. In mitochondria structure, where the space between the inner and outer membranes of these organelles expanded as the matrix was compressed. The electron-dense or swelled was observed as vacuole degeneration and its matrix showed electron-lucent. Compared to control, mitochondria membrane potential increased in every group after 24 h and 48 h treatment. DDP increased intracellular calcium ion in PG cells, however, in PAa cells, JA and DJ decreased it. Intracellular pH got lower at 24 h and higher at 48 h in PG and PAa cells. There were significance in every group vs control in PG and PAa by statistic t-test (P＜0.01). CONCLUSION: Apoptosis was induced in PG and PAa cell lines by Jinan injection and DJ. Mitochondria matrix displayed electron-dense, mitochondrial potential, intracellular calcium ion and pH showed an increasing trend. Mitochondria damages may play an important role in apoptosis induced by Jinan and DJ.     

Proteomic analysis between pathological scars and normal skin

AIM: To investigate and screen the sensitive proteins in the formation mechanism of pathological scars by comparing the results of differential proteomic analysis between pathological scars and normal skin.METHODS: Two-dimensional gel electrophoresis was used to detect the protein expression profiles in 8 keloid patients, 8 hypertrophic scar patients and 3 matched normal skin patients.The proteins that showed differential expression of over 4-fold change were cut and analyzed by MALDI-TOF/TOF mass spectrometry.RESULTS: A two-dimensional protein profiling comparison between pathological scars and normal skin was successfully established.On average, 2 978 spots in keloid, 2 975 spots in hypertrophic scar and 3 053 spots in normal skin were identified using gel analysis software.Compared with normal skin, there were totally 36 differentially-expressed proteins in keloid and hypertrophic scar identified from the spots of over 4-fold change, including 16 proteins in both keloid and hypertrophic scar (8 up-regulated and 8 down-regulated), 11 only in keloid (9 up-regulated and 2 down-regulated) and 9 only in hypertrophic scar (4 up-regulated and 5 down-regulated).CONCLUSION: Proteomic analysis can identify the proteins with variance of pathological scars versus normal skin, thus providing probable new clues to reveal the formation mechanism of pathological scars.

Interpreting habitat distribution models of an elusive species,the marbled murrelets: a response to Burger and Page

Burger and Page (this volume) evaluated our models of habitat preferences and breeding success of a threatened seabird, the marbled murrelet (Brachyramphus marmoratus), based on the largest available set of confirmed nest-sites found in coastal old-growth forest of the Pacific North-West. We believe our study documented novel and unexpected patterns of landscape-level distribution of marbled murrelets in both heavily logged and relatively intact old-growth landscapes and provided insights into how these patterns influence their reproduction, and, eventually, management. Considering the importance of the issue and to ensure appropriate and responsible use of the information we welcome discussion, detailed scrutiny and evaluation of our original results. Burger and Page claim to have identified flaws with model interpretation, data quality, statistical approaches, presentation and interpretation of our results that would invalidate our conclusions. We respond that most of their critique is irrelevant and/or misdirected with respect to our study and the interpretation of GIS data models, and that valid aspects of their claims do not critically affect our conclusions.     

嫁接辣椒对青枯病的抗性及其与渗透调节物质的关系

 青枯病是当前设施辣椒主要的土传病害之一。为了选择抗性砧木和探讨嫁接辣椒的抗病机理,通过人工接种青枯病原菌,分析了不同辣椒品种砧木的发病率和病情指数变化,结果表明：‘富根卫士’（简称‘卫士’）发病晚,发病率低,病情指数最小,抗病性最强。以‘卫士’辣椒为砧木,以‘新丰2号’为接穗进行嫁接,以接穗自根嫁接为对照,研究其发病率、病情指数和渗透调节物质的变化。结果表明：嫁接植株的发病率和病情指数显著低于对照,接种20 d时,嫁接植株发病率和病情指数分别比对照低33%和43%。接种前嫁接的植株根系和叶片的含水量、水势、渗透势均低于对照,束缚水/自由水比值、可溶性糖及脯氨酸含量均高于对照。接种后,辣椒根系和叶片的含水量、水势、渗透势均逐渐降低,束缚水/自由水比值逐渐升高,可溶性糖和脯氨酸含量先升高后降低;与对照相比,嫁接植株根系和叶片的含水量、水势、渗透势的降低幅度及束缚水/自由水比值升高幅度明显较小,可溶性糖和脯氨酸含量显著增加。研究结果表明嫁接可显著提高辣椒青枯病的抗性,其抗病机理与渗透调节能力增强有关。
