The Asian Lineage of Zika Virus: Transmission and Evolution in Asia and the Americas

Since first isolation in 1947 from the Zika forest in Uganda, Zika virus(ZIKV) has been principally known as a benign agent associated with sporadic human infections in a restricted number of African countries. However, during 2015–2016,an Asian lineage of ZIKV caused an unprecedentedly large outbreak in the Americas and sizeable numbers of exported cases across the globe. In this review, we critically appraise the recent advances in molecular epidemiological studies of ZIKV performed to date, and we highlight the pivotal role played by genomic surveillance in elucidating the origins,dissemination and evolution of the Asian lineage of ZIKV in Asia and in the Americas.

Variation of Bioactive Compounds in Hypericum perforatum Growing in Turkey During Its Phenological Cycle

引用

Journal of Integrative Plant Biology 2007年第5期49卷 615-620页

作者： Cüneyt Cirak Jolita Radusiěne Birsen (Saglam) Karabük Valdimaras Janulis Liudas Ivanauskas Faculty of Agriculture Department of Agronomy University of Ondokuz Mayis Samsun 55139 Turkey Institute of Botany Zaliuju ezeru Vilnius LT-08406 Lithuania Kaunas University of Medicine Kaunas LT-44307 Lithuania

The present study was conducted to determine phenologic and morphogeneUc variation of hyperlcln, chlorogenlc acid and flavonoids, as rutin, hyperoside, apigenin-7-O-glucoside, quercitrin, quercetin content of Hypericum perforatum L. growing in Turkey. Wild growing plants were harvested at vegetative, floral budding, full flowering, fresh frulUng and mature fruiting stages and dissected into stem, leaf and reproductive tissues and assayed for bioacUve compounds by the High performance liquid chromatography （HPLC） method. Hypericin concentration ranged between 0 and 2.73 mg/g DW, chlorogenic acid 0.00-3.64 mg/g DW, rutin 0.00-3.36 mg/g DW, hyperoside 0.04- 22.42 mg/g DW, quercitrin 0.03-3.46 mg/g DW and quercetin 0.04-1.02 mg/g DW depending on ontogenetic and morphogenetic sampling. Leaves were found to be superior to stems and reproductive parts with regard to phenolic accumulation for all compounds tested while flowers accumulated the highest levels of hypericln. Quercltrln, quercetln and hypericin content in all tissues increased with advancing of developmental stages and reached their highest level during flower ontogenesis. Similarly, chlorogenic acid, hyperoside and apigenin-7-O-glucoside content in different plant parts increased during plant development, however, the highest level was observed at different stages of plant phenology for each tissue. Chlorogenic acid was not detected in stems, leaves and reproductive parts in several stages of plant phenology and its variation during plant growth showed inconsistent manner. In contrast to the other compounds examined, rutin content of stems and leaves decreased with advanc- ing of plant development and the highest level for both tissues was observed at the vegetative stage. However, content of the same compound in reproductive parts was the highest at mature fruiting. The present findings might be useful to obtain increased concentration of these natural compounds.

Quantifying post logging biomass loss using satellite images and ground measurements in Southeast Cameroon

Journal of Forestry Research 2016年第6期27卷 1415-1426页

Forest logging in the Congo Basin has led to forest fragmentation due to logging infrastructures and felling gaps. In the same vein, forest concessions in the Congo Basin have increasing interest in the REDD＋ mechanism. However, there is little information or field data on carbon emissions from forest degradation caused by logging. To help fill this gap, Landsat 7 and 8 and SPOT 4 images of the East Region of Cameroon were processed and combined with field measurements （measurement of forest roads widths, felling gaps and log yards） to assess all disturbed areas. Also, measurements of different types of forest infrastructures helped to highlight emission factors. Forest contributes to 5.18 % of the degradation of the annual allowable cut （AAC）（84.53 ha） corresponding to 4.09 % of forest carbon stock （6.92 t ha^-1）. Felling gaps constitute the primary source of degradation, represented an estimated area of 32.41 ha （2 % of the cutting area） far ahead of primary roads （18.44ha） and skid trails （16.36 ha）. Assessment of the impact of degradation under the canopy requires the use of high resolution satellite images and field surveys.
