Sand dwelling Turbellaria from the Delta of the Rivers Rhine, Meuse and Scheldt have been investigated. Thirty-eight samples taken from littoral and sublittoral stations in the Grevelingen, Eastern and Western Scheldt have been analysed.Thirty-three species were recorded (Acoela were not considered); twenty-four of them are new for the area and seven new species are described.Density and diversity of Turbellaria were higher in the Eastern Scheldt than in the Western Scheldt or in the Lake Grevelingen. A maximum density of 82 ind./100 cm 3 was noted. A tentative calculation on relative abundance of the representatives of the different Turbellaria orders is established. Proseriata seem to be dominant in the localities studied.Abbreviations acg :

Heparan sulfate (HS) is a sulfated glycosaminoglycan attached to a core protein on the cell surface. Protein binding to cell surface HS is a key regulatory event for many cellular processes such as blood coagulation, cell proliferation, and migration. The concept whereby protein binding to HS is not random but requires a limited number of sulfation patterns is becoming clear. Here we describe a hydrophobic trapping assay for screening a library of heparin hexasaccharides for binders to antithrombin III (ATIII). The hexasaccharide compositions are defined with their building block content in the following format: (DeltaHexA:HexA:GlcN:SO 3:Ac). Of five initial compositions present in the library, (1:2:3:6:1), (1:2:3:7:1), (1:2:3:7:0), (1:2:3:8:0), and (1:2:3:9:0), only two are shown to bind ATIII, namely, (1:2:3:8:0) and (1:2:3:9:0). The use of amide hydrophilic interaction (HILIC) liquid chromatography-mass spectrometry permitted reproducible quantitative analysis of the composition of the initial library as well as that of the binding fraction. The specificity of the hexasaccharides binding ATIII was confirmed by assaying their ability to enhance ATIII-mediated inhibition of Factor Xa in vitro. 相似文献

The specificity of human plasma lecithin-cholesterol acyltransferase for molecular species of phosphatidylcholine (PC) was studied by determining the molecular species composition of whole plasma before and after incubation at 37 degrees C. Since the disappearance of PC under the conditions employed is entirely due to the activity of lecithin-cholesterol acyltransferase, its specificity can be determined from the decrease in the concentration of each species after the reaction. The selectivity factor for each species was calculated by dividing its observed contribution by its concentration at zero time. The major species contributing to cholesterol esterification in whole plasma were 16:0-18:2 (46%), 18:0-18:2 (16%), 16:0-18:1 (15%), 16:0-20:4 (10%), 18:0-20:4 (5%) and 18:1-18:2 (5%). The specificity, as determined from the selectivity factors for whole plasma, was in the order: 16:0-18:2 greater than 18:1-18:2 greater than 16:0-18:1 greater than 18:0-18:2 greater than 16:0-22:6 greater than 18:0-20:4 greater than 16:0-20:4. The high-density lipoproteins (HDL) contained a significantly higher percentage of 16:0-20:4 and 18:0-20:4 and a lower percentage of 16:0-18:1 and 18:0-18:1 compared to the very-low and low-density lipoproteins. These differences disappeared after incubation of the plasma for 24 h. Using selectivity factors for HDL PCs only, the specificity of the enzyme was found to be in the order: 16:0-18:2 greater than 18:1-18:2 greater than 18:1-18:1 greater than 16:0-22:6 greater than 18:0-18:2 greater than 16:0-18:1 greater than 16:0-20:4. These results indicate that in native plasma, lecithin-cholesterol acyltransferase prefers 16:0 greater than 18:1 greater than 18:0 at the 1-position and 18:2 greater than 18:1 greater than 22:6 greater than 20:4 at the 2-position of PC. 相似文献

From data obtained by differential scanning calorimetry phase diagrams were constructed, using a thermodynamically based fitting method. The following binary mixtures of phosphatidylcholines in water were studied: 14:0/14:0-glycerophosphocholine/16:0/16:0-glucerophosphocholine, 14:0/14:0-glycerophosphocholine/18:0/18:0-glycerophosphocholine, 12:0/12:0-glycerophosphocholine/16:0/16:0-glycerophosphocholine, 18:1t/18:1t-glycerophosphocholine/14:0/14:0-glycerophosphocholine and 18:1t/18:1t-glycerophosphocholine/16:0/16:0-glycerophosphocholine. A comparison is made of the present results with those obtained using probe techniques and the differences are discussed. 相似文献

The linear growth of Botrytis cinerea, Fusarium caeruleum and Phoma foveata in culture was reduced in the presence of vapour from any of the three isomers of tetrachloronitrobenzene. The isomers were fungistatic but not fungicidal. Differences in activity were observed amongst the isomers. The 2:3:4:6 isomer was the most active against all three test fungi. 2:3:5:6-TCNB (tecnazene) was more active than 2:3:4:5-TCNB against Botrytis cinerea , but less active against Fusarium caeruleum and Phoma foveata . Two strains of Fusarium caeruleum resistant to the 2:3:5:6 isomer were not resistant to the other two isomers, although they were more resistant than their 2:3:5:6-TCNB sensitive parent strains. Sporulation and sclerotial production by Botrytis cinerea were completely suppressed by 2:3:5:6-TCNB and 2:3:4:6-TCNB but not by the 2:3:4:5: isomer. 相似文献

Summary Molecular species profiles were determined for both phosphatidylcholine (PC) and phosphatidylethanolamine (PE) of mitochondrial and microsomal membrane fractions from liver tissue of thermally-acclimated rainbow trout, Salmo gairdneri. The predominant molecular species of PC were 16:0/22:6, 16:0/18:1, 16:0/20:3 and 16:0/22:5, whereas predominant molecular species of PE were 18:1/20:4, 14:0/16:0, 18:0/22:6 and 18:1/22:6. PE possessed short chain saturates (primarily 14:0/16:0) and monoenes (primarily 14:0/16:1) not present in PC and larger proportions of polyunsaturated (18:0/22:6, 18:0/22:5 and 18:1/22:6. and diunsaturated molecular species than PC. Differences between membrane fractions were most evident in warm (20°C)-acclimated trout. Mitochondria contained higher proportions of long-chain, polyunsaturated molecular species of PE, but less of the corresponding species of PC than other membrane fractions. Rankings based on unsaturation index were accordingly: mitochondria heavy microsomes>light microsomes for PE, but heavy microsomes>light microsomes>-mitochondria for PC. Mitochondria were notable for high proportions of diunsaturated molecular species of both phosphatides. Growth at cold temperatures (5°C) was generally associated with a replacement of shorter chain mono- and dienoic molecular species (16:0/18:1, 16:1/18:1, 14:0/16:2 and 18:1/18:1 in the case of PC and 14:0/16:1, 14:0/16:2 and 16:1/18:1 for PE), and occasionally saturates, with long-chain, polyunsaturated molecular species (for PC, C 36–38: 16:0/22:6, 16:1/22:6, 16:0/20:3 and 16:0/20:5; for PE, C 38–40: 18:1/20:4, 16:1/22:6, 18:0/20:5, 18:2/20:4, 18:0/22:5 and 18:0/22:6). However, compositions of mitochondrial PE and PC from heavy microsomes were not significantly influenced by acclimation temperature. The role of phospholipase A 2, in addition to other metabolic processes, in mediating these changes is discussed.Abbreviations

The major ester-linked fatty acids of the total lipids extracted from Pneumocystis carinii isolated from the lungs of corticosteroid-trcaicd rats were 16:0. 18:0, 18:1, 18:2 and 20:4. Others detected included 14:0, 16:1 and 22:4. The major sphingolipid fatty acids were 16:0, 18:0,22:0,24:0 and 24:1; others included 14:0, 18:1, 20:0, 23:0, 24:2 and 26:0. The total lipid fatty acid compositions of preparations from appropriate lung controls were similar to those of the organism. 相似文献

High-performance counter-current chromatography (HPCCC) and high performance liquid chromatography coupled with mass spectrometry (HPLC-MS) was efficiently utilized for the separation and identification of the chemical components with a wide range of polarity from the mixed extract of Chinese medicinal herb Apocynum venetum. For HPCCC separation, four sets of solvent systems, n-hexane-ethyl acetate-acetonitrile-water (1.5:3.5:2:4.5, v:v:v:v), ethyl acetate-methanol-water (5:2:5, v:v:v) and n-butanol-methanol-water (5:1:5, v:v:v) were used for the one-step separation by four stages. The HPCCC separation was initiated by filling the column with the lower phase of n-hexane-ethyl acetate-acetonitrile-water (1.5:3.5:2:5, v:v:v:v) as a stationary phase followed by elution with the upper phase of n-hexane-ethyl acetate-acetonitrile-water (1.5:3.5:2:5, v:v:v:v) to separate the hydrophobic compounds (tail to head). Then the mobile phase was switched to the upper phase of ethyl acetate-acetonitrile-water (5:3:7, v:v:v) to eluted the moderate hydrophobic compounds, then the mobile phase was switched to the upper phase of ethyl acetate-methanol-water (5:2:5, v:v:v) to eluted the moderate hydrophilic compounds, and finally the hydrophilic compounds still retained in the column was eluted by the upper phase of n-butanol-methanol-water (5:1:5, v:v:v). A total of 16 named compounds including adhyperforin, hyperforin, amentoflavone, biapigenin, quercetin, avicularin, acetylated isoquercetin, acetylated hyperoside, astragalin, trifolin, isoquercetin, hyperoside, querciturone, rutin, chlorogenic acid and quercetin-3-O-β-D-glucosyl-β-D-glucopyranoside were successfully separated via the four sets of solvent systems in one step operation for 130 min. The compounds separated by HPCCC were identified by comparing with mixed standards data of HPLC-MS as well as NMR data. 相似文献

Amerindian Mapuche (Araucanians) are now living in Chile and Argentina at both sides of Andean Mountains. They are anthropologically and genetically different from southernmost South America Patagonian Amerindians. Most of the HLA alleles found in our Mapuche sample are frequent or very frequent in North and South America Amerindians: (1) Class I: A*02:01, A*03:01, A*68:01, B*39:09, B*51:01, (2) Class II: DRB1*03:01, DRB1*04:03, DRB1*07:01, DRB1*08:02, DRB1*14:02, DRB1*16:02. One of the nine most frequent extended haplotypes seems to be from European origin, suggesting the existence of a degree of admixture with Europeans in our Mapuche sample. It has been calculated of about 11 % admixture. Three of the extended haplotypes are also found in other Amerindians and five of them are newly found in Mapuche Amerindians: A*68:01-B*39:09-DRB1*08:02-DQB1*04:02; A*68:01-B*51:01-DRB1*04:03-DQB1*03:02; A*29:01-B*08:01-DRB1*03:01-DQB1*02:01; A*02:01-B*15:01-DRB1*04:03-DQB1*03:02; A*33:01-B*14:02-DRB1*07:01-DQB1*03:03. The medical importance of calculating HLA profile is discussed on the diagnostic (HLA and disease) and therapeutical bases of HLA pharmacogenomics and on the construction of a virtual transplantation HLA list profile. Also, anthropological conclusions are drawn. 相似文献

In Saccharomyces cerevisiae, we synthesized and secreted L-HBVsAg (named as pre-S(Met1 to Asn174)::S(Met175 to Ile400)) and three mutants, i.e., pre-S degree degree::S (Asn15Gln and Asn123Gln), pre-S degree degree::S degree (Asn15Gln, Asn123Gln, and Asn320Gln), and pre-S degree degree::S degree degree (Asn15Gln, Asn123Gln, Asn233Gln, and Asn320Gln). All of the secreted pre-S::S was N-glycosylated, i.e., hyper-mannosylated. In the secretion of pre-S degree degree::S and pre-S degree degree::S degree, besides the hyper-mannosylated form, another immunoreactive protein with much lower molecular mass was observed, which seems to be unglycosylated form of pre-S degree degree::S and pre-S degree degree::S degree. Only a part of the secreted pre-S degree degree::S or pre-S degree degree::S degree molecules was N-glycosylated, and the site for the partial N-glycosylation seems to be Asn233 in S-antigen region. Compared to the N-glycosylated pre-S degree degree::S and pre-S degree degree::S degree, pre-S degree degree::S degree degree (non-N-glycosylated mutant) was secreted with lower secretion efficiency but showed apparent immunoreactivity to anti-S antigen monoclonal Ab. Interestingly, unlike pre-S degree degree::S degree degree with authentic C-terminus, the recombinant pre-S degree degree::S degree degree with C-terminal myc or poly-histidine tag (pre-S degree degree::S degree degree::tag) was almost all aggregated into insoluble proteins in the intracellular region. Conclusively, the C-terminal sequence and glycosylation in S-antigen region seem to be of crucial importance in determining the secretion efficiency of L-HBVsAg in S. cerevisiae. 相似文献

Viral infection causes many physiological alterations in the host cell, and many of these alterations can affect the host mitochondrial network, including mitophagy induction. A substantial amount of literature has been generated that advances our understanding of the relationship between mitophagy and several viruses. Some viruses trigger mitophagy directly, and indirectly and control the mitophagic process via different strategies. This enables viruses to promote persistent infection and attenuate the innate immune responses. In this review, we discuss the events of virus-regulated mitophagy and the functional relevance of mitophagy in the pathogenesis of viral infection and disease.

Plant materials have been widely studied for their preventive and therapeutic effects for type 2 diabetes mellitus (T2DM) and obesity. The effect of a plant material arises from its constituents, and the study of these bioactive compounds is important to achieve a deeper understanding of its effect at the molecular level. In particular, the study of the effects of such bioactive compounds on various biological processes, from digestion to cellular responses, is required to fully understand the overall effects of plant materials in these health contexts. In this review, I summarize the bioactive compounds we have recently studied in our research group that target digestive enzymes, dipeptidyl peptidase-4, myocyte glucose uptake, and lipid accumulation in adipocytes.

BackgroundMolecular modeling of RNA double helices is possible using most probable values of basepair parameters obtained from crystal structure database. The A:A w:wC non-canonical basepair, involving Watson-Crick edges of two Adenines in cis orientation, appears quite frequently in database. Bimodal distribution of its Shear, due to two different H-bonding schemes, introduces the confusion in assigning most the probable value. Its effect is pronounced when the A:A w:wC basepair stacks on Sheared wobble G:U W:WC basepairs. MethodsWe employed molecular dynamics simulations of three possible double helices with GAG, UAG and GAU sequence motifs at their centers and quantum chemical calculation for non-canonical A:A w:wC basepair stacked on G:U W:WC basepair. ResultsWe noticed stable structures of GAG motif with specifically negative Shear of the A:A basepair but stabilities of the other motifs were not found with A:A w:wC basepairing. Hybrid DFT-D and MP2 stacking energy analyses on dinucleotide step sequences, A:A w:wC::G:U W:WC and A:A w:wC::U:G W:WC reveal that viable orientation of A:A::G:U prefers one of the H-bonding modes with negative Shear, supported by crystal structure database. The A:A::U:G dinucleotide, however, prefers structure with only positive Shear. ConclusionsThe quantum chemical calculations explain why MD simulations of GAG sequence motif only appear stable. In the cases of the GAU and UAG motifs “tug of war” situation between positive and negative Shears of A:A w:wC basepair induces conformational plasticity. General significanceWe have projected comprehensive reason behind the promiscuous nature of A:A w:wC basepair which brings occasional structural plasticity. 相似文献

Ovary maturation, oocyte differentiation, and embryonic development in shrimp are highly dependent on nutritional lipids taken up by female broodstocks. These lipids are important as energy sources as well as for cell signaling. In this study, we report on the compositions of major lipids, i.e. phosphatidylcholines (PCs), triacylglycerols (TAGs), and fatty acids (FAs), in the ovaries of the banana shrimp, Penaeus merguiensis, during ovarian maturation. Thin-layer chromatography analysis showed that the total PC and TAG signal intensities increased during ovarian maturation. Further, by using gas chromatography, we found that (1) FAs 14:0, 16:1, 18:1, 18:2, 20:1, and 22:6 proportionally increased as ovarian development progressed to more mature stages; (2) FAs 16:0, 18:0, 20:4, and 20:5 proportionally decreased; and (3) FAs 15:0, 17:0, and 20:2 remained unchanged. By using imaging mass spectrometry, we found that PC 16:0/16:1 and TAG 18:1/18:2/22:6 were detected in oocytes stages 1 and 2. PCs 16:1/20:4, 16:0/22:6, 18:3/22:6, 18:1/22:6, 20:5/22:6, and 22:6/22:6 and TAGs 16:0/16:1/18:3, 16:0/18:1/18:3, 16:0/18:1/18:1, and 16:0/18:2/22:6 were present in all stages of oocytes. In contrast, the PC- and TAG-associated FAs 20:4, 20:5, and 22:6 showed high signal intensities in stage 3 and 4 oocytes. These FAs may act as nutrition sources as well as signaling molecules for developing embryos and the hatching process. Knowledge of lipid compositions and localization could be helpful for formulating the diet for female broodstocks to promote fecundity and larval production. 相似文献
