... The psyllid Bactericera maculipennis (Crawford) (Hemiptera: Triozidae) often cohabits field bindweed (Convolvulus arvensis, Solanales: Convolvulaceae) and other plants with the congeneric psyllid, Bactericera cockerelli (Sulc), in the Pacific Northwestern United States. Bactericera cockerelli is a vector of “Candidatus Liberibacter solanacearum,” the pathogen associated with zebra chip disease of ...

Abstract:
... Online systems for observation reporting by citizen scientists have been operating for many years. iNaturalist (California Academy of Sciences 2016), eBird (Cornell Lab of Ornithology 2016) and Observado (Observation International 2016) are well-known international systems, Artportalen (Swedish Species Information Centre 2016) and Artsobservasjoner (Norwegian Biodiversity Information Centre 2016) ...

Abstract:
... BACKGROUND: Complementary therapists spend considerable time with their patients, especially in the first consultation. The communication between patients and their therapists is important for raising consciousness and activation of the patient’s self-healing power. Thus, the aims in this study were to delineate what complementary therapists regard as essential in patient consultations, their view ...
electricity; embodied energy; energy costs; infrastructure
Abstract:
... Attempts to assess the possibility of deriving all energy from renewable sources typically deal only with the aggregate amount of energy required, and do not consider the implications and difficulties arising from the need for differing forms of energy. In a 100% renewable system some of these forms will have to be provided by conversion from others, mostly from electricity. Conversion involves in ...
... On the vine, phosphorus deficiency causes a reduction in the development of the root system and growth retardation. This study aimed to define the best option in phosphorus fertilization of vines 'Chardonnay' as well of the quality of grape must. The experiments it was carried out by for the Core for Study, Research and Extension in Enology (NEPE2)/UNIPAMPA - Campus Dom Pedrito, RS, Brazil, with g ...
... The non-climacteric ripening characteristics, including delayed peel coloration and pulp softening, of 'Jen-Ju Bar' ('JJB') guava (Psidium guajava L.) is a result of a reduction in the usually massive amount of ethylene produced during the ripening stage. To elucidate the underlying physiological mechanism, four cDNA clones of ACC synthase (PgACS1 and PgACS2) and ACC oxidase (PgACO1 and PgACO2), t ...

Abstract:
... Since 1988, the strawberry breeding programme at East Malling has successfully released 43 cultivars primarily for the Northern European market. The latest cultivar release, 'Malling Centenary', represents the first mainstream cultivar developed under the direction of East Malling Strawberry Breeding Club (EMSBC) which was formed in 2008 to continue the development of new strawberry cultivars at E ...
... In spring 2006 sweet cherry cultivar ʻReginaʼ was planted on Gisela 3, Gisela 5 and Weiroot 72 at three tree spacings 1.5, 2.0 and 2.5 m in several locations of Alpe Adria region in Europe. After the sixth leaf results for tree vigour, productivity and fruit weight were evaluated. Tree vigour was affected by location, rootstock and rootstock × location combination. Trees in Maribor and Sondrio wer ...
... In the history of strawberry breeding, selection for aroma was mainly conducted to avoid untypical flavor notes. The depleted aroma patterns of modern cultivars resulted from fixation on breeding goals like high yield, large, firm and optically attractive fruit. Genetic erosion was clearly demonstrated in comparative studies using old and modern cultivars. Wild species introgression can serve to i ...

Abstract:
... 'Som Kandarn', the local name of a cultivar of Garcinia atroviridis Griff., was found many years ago in Kiriwong village, Nakhon Si Thammarat province, southern Thailand. Growers have planted a few 'Som Kandarn' seedlings in mixed-fruit-cropping orchards in the mountains, especially in low-fertility areas. 'Som Kandarn' has been known in the village as an easy-to-grow fruit tree. Mainly the fruit ...
... Over the last 30 years, (±)-1-(9-fluorenyl)ethyl chloroformate ((±)-FLEC) was used as a chiral derivatizing agent in various analytical applications involving a wide range of endogenous, pharmaceutical and environmentally relevant molecules.This comprehensive review aims to present all the significant aspects related to the state of the art in FLEC labeling and subsequent chiral separation of the ...

Abstract:
... Four new compounds, (+)- and (−)-ecarlottone (1), (±)-fislatifolione (5), (±)-isofislatifolione (6), and (±)-fislatifolic acid (7), and the known desmethoxyyangonin (2), didymocarpin-A (3), and dehydrodidymocarpin-A (4) were isolated from the stem bark of Fissistigma latifolium, by means of bioassay-guided purification using an in vitro affinity displacement assay based on the modulation of Bcl-xL ...
... (+)-Meyeniins A–C (1–3), a novel class of sulfur-containing hexahydroimidazo[1,5-c]thiazole derivatives, were isolated from the tubers of Lepidium meyenii (maca) cultivated in Lijiang, Yunnan province, China. Guided by their biosynthetic hypothesis, a stereocontrolled biomimetic synthesis of meyeniins A–C and their individual enantiomers was efficiently accomplished by a combination of a condensat ...

... (+)-Strebloside, a cardiac glycoside isolated from the stem bark of Streblus asper collected in Vietnam, has shown some potential for further investigation as an antineoplastic agent. A mechanistic study using an in vitro assay and molecular docking analysis indicated that (+)-strebloside binds and inhibits Na⁺/K⁺-ATPase in a similar manner to digitoxin. Inhibition of growth of different high-grad ...

Abstract:
... Two GFPPS linked (+)-thalianatriene (1) and (−)-retigeranin B (2) sesterterpene synthase genes were identified from the genome of Arabidopsis thaliana. 1 possesses an unprecedented 11–6–5 tricyclic ring system, while 2 contains a characteristic 5–5–5–6–5 pentacyclic ring system. Their structures were determined by extensive NMR spectroscopy, chemical derivatization, and X-ray crystallography. The ...
... Endothelial inflammation is an increasingly prevalent condition in the pathogenesis of many cardiovascular diseases. (-)-7(S)-hydroxymatairesinol (7-HMR), a naturally occurring plant lignan, possesses both antioxidant and anti-cancer properties and therefore would be a good strategy to suppress tumor necrosis factor-α (TNF-α)-mediated inflammation in vascular endothelial cells (VECs).: The objecti ...

Abstract:
... Muscle loss is a typical process of aging. Green tea consumption is known to slow down the progress of aging. Their underlying mechanisms, however, remain largely unknown. In this study, we investigated the effect of (-)-epigallocatechin-3-gallate (EGCG), a polyphenolic compound of green tea, on myogenic differentiation and found that EGCG significantly increases myogenic differentiation. After EG ...

Abstract:
... A new composite material consisting of 0D MoS2 nanodots and 3D MoS2 nano-flowers grown on porous reduced graphene oxide (P-rGO) was synthesized via a two-step process. The P-rGO with a surface area of 759 m2 g−1 was obtained by CO2 activation of reduced graphene oxide (rGO) at 800 °C. MoS2 was then grown on the P-rGO under hydrothermal conditions. Compared to the nonactivated rGO, P-rGO has functi ...
... Tin disulfide is considered to be a promising anode material for Li ion batteries because of its high theoretical capacity as well as its natural abundance of sulfur and tin. Practical implementation of tin disulfide is, however, strongly hindered by inferior rate performance and poor cycling stability of unoptimized material. In this work, carbon-encapsulated tin disulfide nanoplates with a (101) ...

Abstract:
... Derivatives of 2,2-dimethyl-3-(2-methylprop-1-enyl)cyclopropanecarboxylic acid (chrysanthemic acid) are classic natural pyrethroids discovered in pyrethrum plants and show insecticidal activity. Chrysanthemic acid, with two asymmetric carbons, has four possible stereoisomers, and most natural pyrethroids have the (1R,3R)-trans configuration. Interestingly, chrysanthemic acid–related structures are ...
