Disease relevance of Salix

• A pilot study of Salix SST (saliva-stimulating lozenges) in post-irradiation xerostomia [1].

High impact information on Salix

• The effect of genotype and cultivation method on the total salicylate yield of dark-leaved willows (Salix myrsinifolia) [2].
• Salicin in the bark extract of Salix alba and amygdalin in the fruit extract of Semen armeniacae were each separated by slow rotary counter-current chromatography (SRCCC) [3].
• Larvae of the leaf beetle Chrysomela lapponica derive a defensive secretion from salicyl glucosides found in the host plant Salix borealis [4].
• We investigated the effects of soil nutrient and water availability on (1) the growth and chemistry of the silky willow (Salix sericea Marshall), and (2) the preference and performance of the imported willow leaf beetle (Plagiodera versicolora Laichartig) [5].
• Two new phytane-type diterpene-gamma-lactones named hanliuine I (1) and hanliuine II (2), were isolated from leaves of Salix matsudana (chinese name "hanliu", Berberidaceae) [6].

Biological context of Salix

• Browse biomass (mostly Salix spp. and Betula nana L.) increased >or=220% (P<or=0.003, Mann-Whitney U-test) from 653 kg/ha in deciduous shrub types [7].

Anatomical context of Salix

• Heat shock protein 47 expression in aged normal human fibroblasts: modulation by Salix alba extract [8].

Associations of Salix with chemical compounds

• Ten clones of dark-leaved willows ( Salix myrsinifolia Salisb.) were grown for two years on two different sites, Luikonlahti and Punkaharju, using various combinations of soil cultivation, fertilization and mulch treatments, with the objective of comparing the effect of different cultivation methods on the growth and total salicylate yield [2].
• We isolated cDNA clones (pSgPG1 through pSgPG4, pSgPME1 and pSgGN1) for the polygalacturonases (PGs), pectin methylesterase (PME) and beta-1,3-glucanase (GN) that are expressed specifically in male flowers of the dioecious willow (Salix gilgiana Seemen) [9].
• We measured an index of heat increment of feeding (HIFi) and CH(4) production in muskoxen (Ovibos moschatus) given a single test meal (at 10 g/kg BM(0.75)) composed of hay mixed with one of three browse species (Willow: Salix alaxensis, S. pulchra; Birch: Betula nana) [10].
• The effect of the method used to express element concentrations on the spatial variability of cadmium (Cd) in the leaves of crack willow (Salix fragilis L.) was investigated by sampling the leaves of one willow at 292 locations in the crown, each sampling location having a volume of 0.027 m3 (0.3 m x 0.3 m x 0.3 m) [11].
• Proanthocyanidin polymers, oligomers, and the structurally related monomer (+)-catechin were labeled by incorporation of radioactive precursors in shoots of willow tree (Salix caprea L.). [1-(14)C]-Acetate and [U-(14)C]-phenylalanine precursors were fed through the cut stems or petioles of leaves [12].

Gene context of Salix

• The IC50-values obtained for the inhibition of lipopolysaccharide (LPS)-induced release of prostaglandin E2 (PGE2) reflecting cyclooxygenase (COX)-2-mediated PGE2 release were 47 microg/ml and 0.6 microg/ml, for the Salix extract 1520L and rofecoxib-like research compound L745337, respectively [13].
• Our results indicate that Salix extract 1520L inhibits COX-2-mediated PGE2 release through compounds other than salicin or salicylate [13].
• In the present investigation, it was observed that the pretreatment of animals with Salix caprea caused a significant (P < 0.05) depletion in the TPA-induced DNA synthesis, ODC and xanthine oxidase activity in mice skin [14].
• Expression of DnaJ homologs and Hsp70 in the Japanese willow (Salix gilgiana Seemen) [15].
• We isolated three cDNA clones (pSGJ1, pSGJ2 and pSGJ3) for DnaJ-like proteins of the Japanese willow (Salix gilgiana Seemen) [15].

Analytical, diagnostic and therapeutic context of Salix

• In preliminary experiments, polyphenol fractions prepared from the leaves of Salix matsudana reduced the elevation of the rat plasma triacylglycerol level at 3 and 4 h after oral administration of a lipid emulsion containing corn oil, at a dose of 570 mg/kg [16].
• We did in situ hybridization to identify the sites at which DnaJ homologs (SGJ1 and SGJ3) and Hsp70 were expressed in male and female flowers of the Japanese willow, Salix gilgiana Seemen [17].
