Bisdioxycalamenene: A Bis-Sesquiterpene from the Soft Coral Rhytisma fulvum fulvum

A dichloromethane extract of the soft coral Rhytisma fulvum fulvum collected in Madagascar afforded a novel compound possessing an unprecedented pentacyclic skeleton, bisdioxycalamenene (1), as well as seven known sesquiterpenes. The structures of the compounds were elucidated using 1D and 2D NMR techniques, as well as high-resolution mass spectrometry. The absolute configuration of 1 was determined using X-ray diffraction analysis and anomalous dispersion effects. The structure elucidation and a possible biogenesis of the compound are discussed.  相似文献   

Nematology Research in Europe     

MauriceMoens 《云南农业大学学报(自然科学版)》1999,14(Z1):111-113

 Nematology started in Europe at the end of the last century.In Belgium and the Netherlands for example the first nematological paper(in Dutch) appeared in 1876.It was prepared by de Man and dealt with soil nematodes.Nematology gradually increased in importance.This lead to the establish-ment of the European Society of Nematologists in 1953.Since then, ESN has arranged a symposium every two years with an increasing number of participants.During the last meeting in Dundee, this number exceeded 450.The Society distributes a membership directory and keeps contact with the members through 'Nematology News'.This newspaper reports on the events in the nematology labs and issued twice a year.  相似文献   

Neuronal Ceroid Lipofuscinosis in Rambouillet Sheep: Characterization of the Clinical Disease     

Philip R. Woods  Ralph W. Storts  Maurice Shelton  Carl Menzies 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》1994,8(5):370-375

A chronic progressive, neurodegenerative disease has been identified in 4 closely related flocks of purebred Rambouillet sheep. Blindness, circling, proprioceptive deficits, reduced cognition, and poor body condition are the main clinical signs. Prominent lesions include markedly decreased cerebral size and weight, enlarged cerebral ventricles, and intraneuronal accumulations of autofluorescent pigment. Affected sheep usually die between 1 and 2 years of age. The clinical signs and postmortem findings are consistent with neuronal ceroid-lipofuscinosis.  相似文献   

Efficacy of gonadotropin-releasing hormone administered at the time of artificial insemination of heifers and postpartum and repeat breeder dairy cows   总被引：1，自引：0，他引：1  

C N Lee  E Maurice  R L Ax  J A Pennington  W F Hoffman  M D Brown 《American journal of veterinary research》1983,44(11):2160-2163

The efficacy of gonadotropin releasing hormone (GnRH) on the fertility of dairy heifers and postpartum cows was studied. In one study, 300 cows were assigned randomly to 1 treatment from a 2 X 2 design, and 2 ml of 0.15M saline solution or 100 micrograms of GnRH was given IM on postpartum day (PPD) 14 and at the time of 1st postpartum breeding. In a 2nd study, repeat breeder cows (n = 346) were given saline solution or GnRH at the time of the 3rd breeding. In a 3rd study, heifers (n = 185) were given saline solution or GnRH at 1st breeding. Animals were observed for repeat estrus, and pregnancy diagnoses were made by rectal palpation 45 to 60 days after breeding. Conception rates were 15% to 18% higher for cows given GnRH, whether at PPD 14 or at the first postpartum breeding. When GnRH was given at the first breeding, conception rates were significantly higher (P less than 0.05). Conception rates for repeat breeder cows given GnRH were 25% higher than those in controls (P less than 0.005). Conception rates for heifers did not differ between treatments.  相似文献   

Shell gland adenosine triphosphatase in hens producing strong and weak egg shells   总被引：1，自引：1，他引：0  

D J Castaldo  D V Maurice 《British poultry science》1990,31(1):225-229

1. Two groups of 4 hens at the end of their first production cycle were classified as producers of strong egg shells (greater than 70 mg/cm2) and weak egg shells (less than 60 mg/cm2) on the basis of shell surface density. 2. Shell gland mucosa was homogenised and fractionated into nuclear, mitochondrial, microsomal and supernatant fractions, and ATPase activity determined. 3. ATPase activity in the total homogenate was significantly greater for hens producing strong shells (SES) than for hens producing weak shells (WES). 4. ATPase activities detected in the nuclear fraction, mitochondria and microsomes were significantly greater for SES than for WES birds.  相似文献

Quantitative detection of the root-lesion nematode, Pratylenchus penetrans, using qPCR

Pratylenchus penetrans is one of the most economically damaging plant-parasitic nematodes and is found on a wide variety of crops. Correct identification and quantification of this nematode are necessary for providing advice to farmers, but are not easily obtained with the traditional way of microscopic observation. We developed a qPCR assay to detect and quantify P. penetrans in a short but accurate manner. A qPCR primer set, including two primers and a TaqMan probe, was designed based on the sequence of the β-1,4-endoglucanase gene. The assay was optimized by using the primers in a qPCR assay with SYBR green I dye and setting the qPCR program to different annealing temperatures ranging from 60 °C to 64 °C. Based on the Ct-values, we retained the program with an annealing temperature of 63 °C. The assay with the probe was very sensitive as it was able to detect a single individual of P. penetrans, even when mixed with up to 80 individuals of P. thornei. The specificity of the reaction was confirmed by the lack of amplification of DNA from 28 populations of 18 other Pratylenchus species and from plant-parasitic nematodes from nine other genera. DNA from 21 different isolates from P. penetrans was amplified. DNA extraction from 80 individuals and quantification by qPCR was repeated four times; Ct-values showed consistent results (Ct?=?24.4?±?0.4). A dilution series from DNA of P. penetrans resulted in a standard curve showing a highly significant linearity between the Ct-values and the dilution rates (R²?=?0.99; slope?=??3.23; E?=?104 %). The tests showed a high correlation between the real numbers of nematodes and the numbers detected by the qPCR. The developed qPCR assay provides a sensitive means for the rapid detection and reliable quantification of individuals of this pest. This method does not require expertise in nematode taxonomy and morphology, and can be used as a rapid diagnostic tool in research, as well as in diagnostic labs and extension services advising farmers for pest management.  相似文献
