Photoemission evidence for a remnant fermi surface and a d-wave-like dispersion in insulating Ca2CuO2Cl2     

F Ronning  C Kim  DL Feng  DS Marshall  AG Loeser  LL Miller  JN Eckstein  I Bozovic  Z Shen 《Science (New York, N.Y.)》1998,282(5396):2067-2072

An angle-resolved photoemission study is reported on Ca2CuO2Cl2, a parent compound of high-Tc superconductors. Analysis of the electron occupation probability, n(k), from the spectra shows a steep drop in spectral intensity across a contour that is close to the Fermi surface predicted by the band calculation. This analysis reveals a Fermi surface remnant, even though Ca2CuO2Cl2 is a Mott insulator. The lowest energy peak exhibits a dispersion with approximately the &cjs3539;coskxa - coskya&cjs3539; form along this remnant Fermi surface. Together with the data from Dy-doped Bi2Sr2CaCu2O8+delta, these results suggest that this d-wave-like dispersion of the insulator is the underlying reason for the pseudo gap in the underdoped regime.  相似文献

Detection of Coxiella burnetii in buffaloes aborted fetuses by IS111 DNA amplification: A preliminary report   总被引：1，自引：0，他引：1  

A.G. Perugini  F. Capuano  A. Esposito  C. Marianelli  A. Martucciello  G. Iovane  G. Galiero 《Research in veterinary science》2009,87(2):189-191

The aim of this study was to evaluate by PCR analyses the presence of Coxiella burnetii infection in fetuses of water buffalo (Bubalus bubalis) in the Campania region (Southern Italy). Samples were collected only from aborted fetuses and C. burnetii presence was evaluated by one-tube nested PCR amplification of the IS111 repetitive element. Of the 164 fetuses examined 14 (17.5%) were positive after DNA amplification, showing that C. burnetii occurs in this population of water buffaloes.However, more extensive prevalence studies need to be carried out to define the role of buffaloes as reservoirs for this pathogen and also the role of C. burnetii as an abortive agent in this animal.  相似文献   

Regional distribution and integrity of equine ovarian pre‐antral follicles          下载免费PDF全文

The goal of this study was to determine the distribution of pre‐antral follicles in the ovarian parenchyma of mares. For Experiment 1, each ovary was cut longitudinally at the greater curvature, performing two hemiovaries. After that, six fragments from each hemiovary were obtained, resulting in 12 fragments, which were divided into the innermost region of the parenchyma, the middle region and the outermost region. All the three obtained sections were cut transversally to obtain two fragments from each one. For Experiment 2, each ovary also submitted to a longitudinal cut on the greater curvature, forming two hemiovaries. Each hemiovary was sectioned into four symmetrical fragments, resulting in eight fragments per ovary. The fragments were related as being near to or far from the ovulatory fossa. The fragments of both experiments were immediately fixed in Carnoy for 12 hr and kept in 70% ethanol for 24 hr. Follicles were classified according to the stages of development and for morphological integrity according to oocyte morphology and granulosa cells. After the histological assessment, a total of 1,130 follicles were visualized from Experiment 1, being 1,054 (93.3%) primordial follicles and 76 (4.7%) follicles in development. The innermost region had the highest percentage of pre‐antral follicles compared to the other regions (p < .05). The middle and outermost regions showed higher percentages of intact primordial and developing follicles than the innermost region (p < .05). Considering Experiment 2, 938 follicles were found, being 894 (95.3%) primordial and 44 (4.7%) follicles in development. The region near the ovulatory fossa presented higher (58.7%; 551 of 938) follicular concentration compared to the region far from the ovulatory fossa (41.3%; 387 of 938; p < .05). As a conclusion, distribution of pre‐antral follicles in the equine ovary has a specific pattern through the parenchyma. Also, the follicular integrity differed in the studied ovarian areas.  相似文献

Molecular update on cystic echinococcosis in cattle and water buffaloes of southern Italy     

Rinaldi L  Maurelli MP  Capuano F  Perugini AG  Veneziano V  Cringoli S 《Zoonoses and public health》2008,55(2):119-123

Cystic echinococcosis (CE)--caused by the larval stage (hydatid cyst) of the cestode Echinococcus granulosus--is one of the most widespread zoonoses of veterinary and medical importance. Molecular techniques have allowed the identification of 10 different genotypes (G1-G10) of the parasite. The present paper is an update regarding the E. granulosus genotypes infecting water buffaloes and cattle bred in the Campania region of southern Italy. The molecular study was performed on 30 hydatid cysts (11 from water buffaloes and 19 from cattle). Two different mitochondrial DNA genes, namely the cytochrome c oxidase subunits 1 and the 12S ribosomal DNA (12S rDNA) were used as genetic markers. Three different genotypes of E. granulosus were unequivocally identified, i.e. the G1 (common sheep), G2 (Tasmanian sheep) and G3 (buffalo) genotypes, as well as some G1 and G2 variants. It should be noted that the present study demonstrated for the first time: (i) the presence of the G2 genotype in water buffaloes from a Mediterranean area; and (ii) the fact that the analysed portion of the 12S rDNA gene can not discriminate between the G2 and G3 genotypes of E. granulosus. The finding of the G1, G2 and G3 genotypes in large ruminants from southern Italy is of epidemiological relevance and immediate public health importance because of their recognized infectivity in humans.  相似文献
