Ventricular candidiasis in stone curlews (Burhinus oedicnemus)     

Caliendo V  Bull A 《Avian diseases》2011,55(3):509-512

Ventricular candidiasis is consistently one of the most prominent pathologic conditions diagnosed in stone curlews (Burhinus oedicnemus) in the United Arab Emirates, predominately affecting the captive population. Predisposing factors are a humid environment, stress, immunosuppression, inadequate nutrition, and an extended use of oral antibiotics. In this report, we describe the clinical signs, diagnosis, and pathologic result in stone curlews with ventricular candidiasis.  相似文献

The effects of different land-use histories on contents of soil carbon (C) and nitrogen (N) and fluxes of greenhouse gases [carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O)] measured using the closed chamber method were investigated in the Arkaim museum reserve located in the South Ural of Russia. A natural forest site (NF) and two grassland sites that had different land-use histories (CL: cropland until 1991; PST: pasture until 1991; both sites have been fallow for 18 years) were selected for soil sampling and gas flux measurements. The vegetation in NF was mainly Betula pendula Roth. with steppe cherry and grassy cover. Perennial grasses (Stipa spp., Festuca spp. and others) have been planted in CL and PST since 1991 to establish reserve mode, and the projective cover of these plants were?>?90% in both sites in 2009. Soil samples were taken from the A horizon in the three sites, and additionally samples of the O horizon were taken from NF. The contents of soil C and N [total C, total N, soluble organic C, soluble N and microbial biomass C (MBC)] in the O horizon of NF were the largest among all investigated soils (p?p?2 fluxes (i.e., CO₂ efflux) in all three investigated sites were observed. The CO₂ efflux in NF was significantly larger than in CL and PST (129, 30 and 25?mg C m^?2 hour^?1, respectively, p?2 efflux between CL and PST. There were no significant differences in the fluxes of CH₄ and N₂O among NF, CL and PST (p?>?0.05). Our current research indicated that, in soils of the Eurasian steppe zone of Russia, total C, total N and MBC were affected not only by current land-use (i.e., fallow grassland vs. natural forest) but also by past (until 18 years ago) land-use.  相似文献   

The ecology of the endemic quillwort Isoëtes malinverniana: From basic research to legal and in situ conservation     

Thomas Abeli  Cecilio F. Caldeira  Elena Barni  Consolata Siniscalco  Valentina Parco  Graziano Rossi 《水产资源保护:海洋与淡水生态系统》2020,30(9):1719-1722

1. Scientific publications on the conservation of threatened species can drive practical conservation solutions for endangered species. Yet, a posteriori assessment of the impact of such publications is rarely seen in the scientific literature.
2. The impact of two articles published in Aquatic Conservation: Marine and Freshwater Ecosystems (AQC) on the conservation of the endangered quillwort Isoëtes malinverniana is assessed. The articles were the result of a 10‐year study on the focal species that eventually led to the first reintroduction of I. malinverniana. The first article described the development of a cost‐effective model for the selection of suitable reintroduction sites for the species. The second article provided a summary of the techniques used to reintroduce the species and included techniques of ex situ propagation, recipient site preparation, planting methods, and monitoring.
3. This article reviews the practical conservation actions for I. malinverniana that followed the publication of two AQC papers and how they may affect research and conservation for other quillworts and aquatic macrophytes.
4. The results were surprising and went well beyond the initial expectations of the authors. Both AQC publications stimulated the conservation of I. malinverniana from different points of view. They contributed by informing scientists and policymakers of the risk of extinction of this species, leading to the establishment of a new protected area in Piedmont (northern Italy).
5. Our published data represent a sound starting point for funding opportunities in the context of the European Union LIFE programme. Further impacts include an expansion of knowledge on oligotrophic habitat management, the assessment of conservation status, and the education of the general public, with the last of these greatly enhanced by the two ex situ collections created in the botanic gardens of Tourin and Pavia. Interestingly, other authors are now using our approach in research and conservation on other endemic and endangered quillworts worldwide.

2,3,7,8-Tetrachlorodibenzo-p-dioxin influences bovine herpesvirus 1 replication through upregulation of SIRT3 and cytoskeletal reorganization

Infection of kidney cells (MDBK) with Bovine Herpesvirus 1 (BoHV-1) is affected by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), which accelerates BoHV-1-induced apoptosis and increases virus replication. Herein, to elucidate the mechanism through TCDD modifies BoHV-1 infection, we analyzed the modulation of a members of Sirtuin proteins family in MDBK cells. We found that mitochondrial SIRT3 was upregulated during infection. This change was accompanied by cytoskeletal rearrangements and cell extensions. All these trends were drastically modified by TCDD. We hypothesize that, taken together, these results might further clarify the processes responsible for the action of TCDD on the BoHV-1 replication, resulting in enhanced virus production.  相似文献

Cryopreservation of Malus cultivars: Comparison of two droplet protocols     

Adela Halmagyi  Constantin Deliu  Valentina Isac 《Scientia Horticulturae》2010

Two droplet procedures, droplet-vitrification (PVS2) and droplet (DMSO) were applied for cryopreservation of in vitro cultured apple (Malus domestica Borkh., cvs. Florina, Idared, Colmar and Rebra) plants. The highest post-thaw regrowth rates (70% for cv. Florina, 66% for cv. Idared, 63% for cv. Colmar and 60% for cv. Rebra) were achieved after using the droplet-vitrification (PVS2) protocol. The excised shoot tips (2–3 mm in length) were precultured in 0.5 M sucrose enriched media for 24 h. Subsequently they were transferred in PVS2 vitrification solution for 30 or 40 min (depending on cultivar) at 24 °C and then immersed in liquid nitrogen. Rewarming was performed in liquid MS medium at 24 °C. Plants regenerated from cryopreserved shoot tips did not display any sign of morphological alteration or abnormalities in growth in comparison with control plants.  相似文献   

Pharmacokinetics of Tramadol after Epidural Administration in Horses     

Mario Giorgi  Giuseppe Saccomanni  Valentina Andreoni 《Journal of Equine Veterinary Science》2010

Tramadol is a centrally acting analgesic structurally related to codeine and morphine. The aim of the present study was to evaluate the pharmacokinetic of tramadol and its major metabolites after caudal epidural administration in the horse. Six gelding male adult horses were assigned to receive epidural administration of tramadol at 2 mg/kg. Plasma substances detection was achieved using a HPLC-FL method. Tramadol was detectable after 5 minutes up to 8 hours after epidural administration. Metabolites plasma concentrations were found under the limit of quantification of the method; however negligible amounts of M2 was detected from 30 min up to 1 hour in three subjects. In conclusion, this study shows that tramadol administered by caudal route in horses produces plasma concentrations within the extrapolated therapeutic range from humans for sufficient time to provide analgesia. Further study of the drug's safety and efficacy for the treatment of pain in horses is warranted.  相似文献   

Sperm motility and fertilization performance of Nodipecten nodosus (L., 1758) exposed at two different cryoprotectants          下载免费PDF全文

Fausto Silvestri  Valentina Vitiello  Francesco Del Prete  Adele Fabbrocini  Jaime Fernando Ferreira  Giovanni Sansone 《Aquaculture Research》2016,47(2):624-631

Cryopreservation is a valuable tool for aquaculture as it provides continuous seed production, regardless of the spawning season of the brood stock. The selection of a suitable cryoprotectant with low toxicity and high water solubility is important to avoid membrane injuries and intracellular ice crystallization. This study has been aimed at the assessment of the toxic effects of two usually applied cryoprotectants, 1‐2 propylene glycol (PG) and methanol (MetOH), on spermatozoa of the of lion‐paw scallop Nodipecten nodosus, by evaluating the sperm motility and the development of D larvae after fertilization procedure. Sperm was exposed at room temperature (22°C) for 10, 20 and 30 min to different concentration ranges of two cryoprotectants. Regarding the sperm motility, PG5%, PG7%, MetOH4% and MetOH6% did not show differences compared to control (semen incubated in seawater) (P < 0.05). The development of D larvae was not affected by the exposition to PG5%, MetOH 4% and MetOH 6%. These results indicate the potential use of both cryoprotectants for cryopreservation procedures.  相似文献   

Effects of dietary yeast Saccaromyces cerevisiae on the antioxidant system in the liver of juvenile sea bass Dicentrarchus labrax     

Santacroce MP  Merra E  Centoducati G  Zacchino V  Casalino E 《Fish physiology and biochemistry》2012,38(5):1497-1505

The main goal of this work was to determine the effect of dietary live yeast Saccharomyces cerevisiae on the oxidative status of sea bass Dicentrarchus labrax juveniles. Fishes were fed on three diets: the GM group were fed a diet containing lyophilized yeast grown on grape must, the CS group were fed a diet containing lyophilized yeast grown on cornstarch, and the control group were fed a diet without yeast. The activity of the main antioxidative enzymes, superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase, glutathione S-transferase (GST), and glutathione (GSH) content, as well as lipid peroxidation, was measured in the liver of sea bass juveniles 90?days after hatching. Supplementation of the diet with S. cerevisiae significantly reduced the SOD and CAT activity, increased the GST activity, decreased the GSH content, and had no effect on lipid peroxidation. The results support the already reported radical-scavenging properties of yeast and usefulness of its employment as antiperoxidative agent in fish.  相似文献
