Sand dwelling Turbellaria from the Netherlands Delta area

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 cm³ 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 : accessory glands - aco : accessory organ - ad : atrial diverticle - b : bursa - br : brain - cil : cilia - cm : circular muscle - cn : cnidosac - co : copulatory organ - cs : cuticular spines - css : cuticular stylet sheat - de : ejaculatory duct - di : ductus intervesicularis - ds : seminal duct - dsp : spermatic duct - en : enteron - fd : female duct - fp : femal pore - ga : genital atrium - gf : glands in female duct - gg : glands - gp : genital pore - hp : adhesive papillae - ivs : intra capsular seminal vesicle - lm : longitudinal muscle - m : mouth - mp : male pore - ov : ovary - p : proboscis - pg : proboscisglands - ph : pharynx - phg : pharyngial glands - r : retractor muscle - rh : rhabdites - rhg : rhabdite glands - rs : seminal receptacle - s : stylet - sta : statocyst - ut : uterus - t : testis - v : vagina - vg : prostate vesicle - vi : vitellary - vs : seminal vesicle     

Sheep gene mapping: additional DNA markers included (CASB, CASK, LALBA, IGF-1 and AMH).

DNA extracted from 25 hamster-sheep hybrid cell lines was subjected, after Southern blotting, to hybridization with CASB, CASK, LALBA, IGF-1 and AMH cDNA probes. CASB and CASK segregated together and IGF-1 and LALBA were found syntenic with the LDHB-PEPB-TPI-GAPD-SHMT-KRTB group.

Comprehensive separation and identification of chemical constituents from Apocynum venetum leaves by high-performance counter-current chromatography and high performance liquid chromatography coupled with mass spectrometry

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.

Viral strategies for triggering and manipulating mitophagy

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.

Double bond localization in minor homoallylic fatty acid methyl esters using acetonitrile chemical ionization tandem mass spectrometry

Double bond position in natural fatty acids is critical to biochemical properties, however, common instrument-based methods cannot locate double bonds in fatty acid methyl esters (FAME), the predominant analysis form of fatty acids. A recently described mass spectrometry (MS) method for locating double bonds in FAME is reported here for the analysis of minor (<1%) components of real FAME mixtures derived from three natural sources; golden algae (Schizochytrium sp.), primate brain white matter, and transgenic mouse liver. Acetonitrile chemical ionization tandem MS was used to determine double bond positions in 39 FAME, most at concentrations well below 1% of all fatty acid methyl esters. FAME identified in golden algae are 14:1n-6, 14:3n-3, 16:1n-7, 16:2n-6, 16:3n-6, 16:3n-3, 16:4n-3, 18:2n-7, 18:3n-7, 18:3n-8, 18:4n-3, 18:4n-5, 20:3n-7, 20:4n-3, 20:4n-5, 20:4n-7, 20:5n-3, and 22:4n-9. Additional FAME identified in primate brain white matter are 20:1n-7, 20:1n-9, 20:2n-7, 20:2n-9, 22:1n-7, 22:1n-9, 22:1n-13, 22:2n-6, 22:2n-7, 22:2n-9, 22:3n-6, 22:3n-7, 22:3n-9, 22:4n-6, 24:1n-7, 24:1n-9, and 24:4n-6. Additional FAME identified in mouse liver are 26:5n-6, 26:6n-3, 28:5n-6, and 28:6n-3. The primate brain 22:3n-7 and algae 18:4n-5 are novel fatty acids. These results demonstrate the usefulness of the technique for analysis of real samples. Tables are presented to aid in interpretation of acetonitrile CIMS/MS spectra.     

Bioactive compounds in plant materials for the prevention of diabetesand obesity

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.

Redox status of patients before cardiac surgery

Objectives: Redox regulation plays a crucial role in balancing the cardiovascular system. In this prospective study we aimed to identify currently unknown correlations valuable to cardiovascular research and patient management.

Methods: Blood samples from 500 patients were collected directly before cardiosurgical interventions (Ethics Committee reference number 85/11). Four central redox parameters were determined together with about 30 clinical, anthropometric, and metabolic parameters.

Results: Creatinine levels and pulmonary hypertension were significant predictors of the total antioxidant status (TAOS) in the patients; total glutathione levels were linked to C-peptide, and creatinine, gender, and ventricular arrhythmia influenced nitrate/nitrite levels. Notably, significant interactions were found between medication and redox parameters. Calcium channel blockers (CCBs) were positive predictors of total glutathione levels, whereas angiotensin-converting enzyme inhibitors and CCBs were negative predictors of NOx levels. Age showed the highest correlation with the duration of the intensive care stay, followed by NOx levels, creatinine, TAOS, and C-reactive protein.

Discussion: In this prospective study we determined multiple correlations between redox markers and parameters linked to cardiovascular diseases. The data point towards so far unknown interdependencies, particularly between antihypertensive drugs and redox metabolism. A thorough follow-up to these data has the potential to improve patient management.

栽培介质、营养液及化学药剂对红掌生长开花的影响

采用泥炭:珍珠岩:沙(1:1:1)、珍珠岩和水3种栽培介质及3个配方的营养液对红掌进行无土栽培,结果表明,以水作为介质,营养液配方为N:P₂O₅:K₂O=4:1:8的培养液对红掌株高、叶片数及植株净重的增加效果最好,但水培对红掌开花无促进作用。以水为介质的红掌经高温(32℃)胁迫后叶片黄化数为零,显著低于其它处理组;而在泥炭:珍珠岩:沙(1:1:1)介质中,则是6-BA处理的叶片黄化数明显低于其它处理组。     

The influence of N-glycosylation and C-terminal sequence on secretion of HBV large surface antigen from S. cerevisiae

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.

Synthesis of a burkholdine analogue containing β-hydroxytyrosine

Synthesis of a β-OHTyr-containing Bk analogue, a cyclic octalipopeptide with antifungal activities, is described. Since β-OHTyr-containing peptides generally are unstable in strong acidic conditions, synthesis of β-HOTyr-containing peptides by SPPS have rarely been reported. To overcome this problem, we found that using distilled TFA removed the protecting groups of side chains of β-OHTyr-containing Bk analogue, which was prepared by Fmoc-SPPS.

Characteristics of Synthesis of Very-Long-Chain Saturated and Tetraenoic Fatty Acids in Swine Cerebral Microsomes

The elongation of arachidoyl-CoA (20:0-CoA) yielded 22:0 and 24:0 concomitantly, whereas the elongation of behenoyl-CoA (22:0-CoA) yielded only a negligible amount of 24:0 in adult swine cerebral microsomes. The dependence on time, pH, and the substrate concentrations were examined for the synthesis of 22:0 and 24:0 from 20:0-CoA. A microcomputer-aided simulation study suggested that there were two parallel pathways in the elongation of 20:0-CoA to 22:0 and 24:0. The elongation of 22:0-CoA could not be observed in adult swine cerebral microsomes; however, it was observed clearly in newborn swine and rat brain microsomes. A dilution experiment with the addition of cold 22:0-CoA in the reaction of elongation of 20:0-CoA confirmed the above suggestion that no intermediate 22:0 appeared during the synthesis of 24:0 from 20:0-CoA. The elongation of endogenous 20:4-CoA to 22:4 and 24:4 was examined in newborn swine cerebral microsomes, and the presence of two parallel pathways in the elongation of 20:4-CoA to 22:4 and 24:4 similar to those involved in the elongation of 20:0-CoA to 22:0 and 24:0 was suggested.     

MATERNAL INHERITANCE AND ITS EFFECT ON ADAPTIVE EVOLUTION: A QUANTITATIVE GENETIC ANALYSIS OF MATERNAL EFFECTS IN A NATURAL PLANT POPULATION

A mother can influence a trait in her offspring both by the genes she transmits (Mendelian inheritance) and by maternal attributes that directly affect that trait in her offspring (maternal inheritance). Maternal inheritance can alter the direction, rate, and duration of adaptive evolution from standard Mendelian models and its impact on adaptive evolution is virtually unexplored in natural populations. In a hierarchical quantitative genetic analysis to determine the magnitude and structure of maternal inheritance in the winter annual plant, Collinsia verna, I consider three potential models of inheritance. These range from a standard Mendelian model estimating only direct (i.e., Mendelian) additive and environmental variance components to a maternal inheritance model estimating six additive and environmental variance components: direct additive and environmental variances; maternal additive and environmental variances; and the direct-maternal additive () and environmental covariances. The structure of maternal inheritance differs among the 10 traits considered at four stages in the life cycle. Early in the life cycle, seed weight and embryo weight display substantial , a negative , and a positive . Subsequently, cotyledon diameter displays and of roughly the same magnitude and negative . For fall rosettes, leaf number and length are best described by a Mendelian model. In the spring, leaf length displays maternal inheritance with significant and and a negative . All maternally inherited traits show significant negative . Predicted response to selection under maternal inheritance depends on and as well as . Negative results in predicted responses in the opposite direction to selection for seed weight and embryo weight and predicted responses near zero for all subsequent maternally inherited traits. Maternal inheritance persists through the life cycle of this annual plant for a number of size-related traits and will alter the direction and rate of evolutionary response in this population.     

灰飞虱体内WO噬菌体和Wolbachia的侵染关系

WO噬菌体是侵染节肢动物体内感染的Wolbachia的细菌病毒, 人们推测WO噬菌体可能参与了寄主遗传变异的过程。我们对采自中国境内4个地理种群（上海闵行、 云南普洱、 山东济宁和宁夏青铜峡）的灰飞虱Laodelphax striatellus 1~2龄若虫用抗生素HCl-tetracycline处理过的水稻饲养, 每隔20 d取样测定并比较其体内Wolbachia和WO噬菌体的感染率, 以此来初步研究灰飞虱体内WO噬菌体与Wolbachia的侵染关系, 结果表明: WO噬菌体感染率的变化趋势与其宿主Wolbachia的基本一致, 都随着时间推移逐步下降。我们进一步对未经HCl-tetracycline处理的灰飞虱, 用实时定量PCR的方法对WO噬菌体和Wolbachia在不同日龄灰飞虱雌虫体内的菌量进行测定, 结果显示, 二者菌量都随着日龄的增长有所变化, 在第8天达到最大, 二者的变化趋势基本一致。由此我们推断WO噬菌体是侵染胞内共生菌Wolbachia的专性病毒, 并且感染Wolbachia的WO噬菌体很可能是溶原性的噬菌体。     

Carbon : nitrogen : phosphorus ratios influence biofilm formation by Enterobacter cloacae and Citrobacter freundii

AIMS: To test the effects of C : N : P ratio modification of a well-known nutrient medium formulation, the Endo formulation on biofilm formation by Enterobacter cloacae Ecl and Citrobacter freundii Cf1 in both single-species and binary species biofilms. METHODS AND RESULTS: The C : N : P atom : atom ratio of a well-known nutrient medium formulation, the Endo formulation, that has been applied in fermentative biohydrogen studies, was modified to include two different C concentrations, one containing 17.65 g l(-1) and the other 8.84 g l(-1) sucrose, each containing four different C : N : P ratios, two at higher C : N : P ratios (334 : 84 : 16.8 and 334 : 84 : 3) and two at lower C : N : P ratios (334 : 28 : 5.6 and 334 : 28 : 1). Attached cells were enumerated after dislodging the biofilms that had formed on granular activated carbon (GAC). The modified medium containing 17.65 g l(-1) sucrose and having a C : N : P ratio of 334 : 28 : 5.6 resulted in significantly (P < 0.05) higher counts of attached cells for both single-species biofilms at 7.73 log(10) CFU g(-1) GAC and 9.3 log(10)CFU g(-1) GAC for Ent. cloacae Ecl and Cit. freundii Cf1, respectively, and binary species biofilms at 8.2 log(10) CFU g(-1) GAC and 6.34 log(10) CFU g(-1) GAC for Ent. cloacae Ecl and Cit. freundii Cf1, respectively. Scanning electron micrographs showed qualitative evidence that the 334 : 28 : 5.6 ratio encouraged more complex and extensive biofilm growth for both single-species and binary species biofilms. CONCLUSIONS: The differences in the attachment numbers between the different ratios were found not to be a result of the individual actions of the bacterial isolates involved but rather because of the effects of the various C : N : P ratios. The 334 : 28 : 5.6 ratio showed significantly (P < 0.05) higher counts of attached cells for both single-species and binary species biofilms. SIGNIFICANCE AND IMPACT OF THE STUDY: This study indicates that C : N : P ratios should be a key consideration with regard to maximizing biofilm formation in shake flask and fluidized bed bioreactor studies as well as understanding fundamental factors affecting biofilm growth in natural environments.
