Summary1. A modified IBR virus was produced by rapid passages and terminal dilutions in bovine embryo kidney tissue culture. Its avirulence was demonstrated by intramuscular and intranasal inoculation of susceptible cattle. 2. Modified virus inoculated intramuscularly elicits an immune response which protects cattle against challenge with virulent virus. 3. The virus did not spread from intramuscularly-inoculated cattle to susceptible contacts, and could not be reisolated from blood or nasal washings ...

The use of sequential injection analysis (SIA), as applied to the control of environmental parameters, is reviewed. Its advantages and drawbacks are compared with those of flow injection analysis (FIA). FIA is simpler and easier to handle, has a higher sample throughput, and may be controlled manually, but SIA is more robust and versatile and better adapted for multiparametric and stopped flow techniques.

Abstract The effect of sewage sludge applications on extractability and uptake by chard and lettuce of soil cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), leaf (Pb), and zinc (Zn) was investigated. Ten different treatments (0, 150, 300, and 500 kg N ha‐1) as mineral fertilizer, and 400, 800, and 1,200 kg N ha‐1 of aerobically and anaerobically‐digested sewage sludges were applied annually to a sandy‐loam soil since 1984. Seven years after the start of the treatments, higher levels of heavy metals ...

An agent producing a cytopathogenic effect has been isolated in bovine embryo tissue culture cells from upper respiratory tissues of cattle having the disease of infectious bovine rhinotracheitis. Lack of growth in bacteriological culture media, resistance to antibiotics such as penicillin and streptomycin, and ability to pass through fine porosity filters demonstrates that this agent is a virus. Reproduction of a disease in experimental cattle identical to that which occurs naturally, protection ...

Abstract The target of rapamycin (TOR) is a protein kinase with numerous functions in cell growth control. Some of these functions can be potently inhibited by rapamycin, an immunosuppressive and potential anticancer drug. TOR exists as part of two functionally distinct protein complexes. The functions of TOR complex 1 (TORC1) are effectively inhibited by rapamycin, but the mechanism for this inhibition remains elusive. The identification of TORC2 and recent reports that rapamycin can inhibit TORC2 ...

Bovine Leukosis Virus (EBLV) is a widely distributed pathogen agent in the bovine population of many countries, especially in dairy cattle. Once the bovine is infected, it remains as a virus carrier for life and such state is correlated with a specific antibody detectable level. In this study the evaluation of an indirect ELISA (Leucokit-La Plata) to detect antibodies against EBLV is presented. Comparing it with the Immunodiffusion as gold standard test, the sensitivity is 98.93%, the specificity ...

Accurate identification of sex in birds is important for the management and conservation of avian wildlife in several ways, namely in the development of population, behavioral and ecological studies, as well as in the improvement of ex situ captive breeding programs. In general, nestlings, juveniles and adult birds of a wide number of sexually monomorphic species cannot be sexed based on phenotypic traits. The development of molecular methodologies for avian sexing overcame these difficulties, allowing ...

The critical thermal maxima (CTMax) of Farfantepenaeus aztecus was not affected significantly by salinity (P>0.05). A direct relationship was obtained between the critical temperature and the acclimation temperature which increased at intervals of 3–5 °C. The end point of CTMax in F. aztecus was loss of righting response (LRR). The acclimation response ratio (ARR) for the juveniles of the brown shrimp ranged between 0.20 and 0.80, which agreed with others obtained for crustaceans from tropical and subtropical ...

Abstract The binucleate trophoblast giant cells (BNC) of the water buffalo, Bubalus bubalis, placenta were studied, with emphasis on the synthesis of BNC‐specific proteins. Placentomal tissues of 27 water buffalos (2–10 months of pregnancy) were processed for light and electron microscopy. The frequency of BNCs was 20% of the trophoblastic cells in 2–3‐month placentas and increased to 27% in the later stages. Ultrastructurally, binucleate cells displayed a prominent granular endoplasmic reticulum ...

Alstroemeria aurea is a clonal perennial which occurs in the understory of the southern Andean forests. Plants consist of a series of 3-5 vegetative shoots and usually one flowering shoot sprouting each growing season from an underground rhizome. Inflorescences are terminal and synchronously protandrous. We compared the effects of defoliation of the flowering shoot on flower size, nectar production, pollen removal and deposition, and pollen grain size. Treatments were designed to test for the effects ...

Earlier studies indicate that some plant species allocate more mass to produce longer spines in shoots resprouting after browsing. Here we present, for the first time, evidence that fire induces a similar response. Many terrestrial herbivores may benefit from fire through the enhanced availability of fast growing species colonizing or re-sprouting in burned areas. It is less clear whether post-fire plant growth responds to the enhanced risk of herbivory by an increased investment in defensive traits. ...

Abstract High‐resolution melting ( HRM ) analysis is a very attractive and flexible advanced post‐ PCR method with high sensitivity/specificity for simple, fast and cost‐effective genotyping based on the detection of specific melting profiles of PCR products. Next generation real‐time PCR systems, along with improved saturating DNA ‐binding dyes, enable the direct acquisition of HRM data after quantitative PCR . Melting behaviour is particularly influenced by the length, nucleotide sequence and GC content ...

The urgent need to mitigate the emissions of gases that contribute to climate change is creating a new scenario for the international trade of goods and services. Countries that are making efforts to reduce those emissions are now demanding that imported goods contain low levels of embedded carbon for those goods to fairly compete with locally produced products. For this purpose the implementation of standards such as the "carbon footprint" becomes critical. Carbon footprint is an environmental sustainability ...

Neuropeptide mediated signalling is an ancient mechanism found in almost all animals and has been proposed as a promising target for the development of novel drugs against helminths. However, identification of neuropeptides from genomic data is challenging, and knowledge of the neuropeptide complement of parasitic flatworms is still fragmentary. In this work, we have developed an evolution-based strategy for the de novo discovery of neuropeptide precursors, based on the detection of localised sequence ...

Riverine suspended particulate matter (SPM) is an important vector for the transfer of nutrients and contaminants to the Sea. Mediterranean rivers are naturally rich in SPM, but their fluxes have been largely altered in the past decades because of damming. Based on empirical modeling, combining literature estimates on SPM fluxes with the environmental characteristics of the corresponding drainage basins, we present for the first time a spatially explicit quantification of the natural fluxes at the ...

Myiasis is a parasitic infestation resulting from flies laying eggs in the host tissues. It is common in animals, but can also occur in humans, including in the oral cavity. The diagnosis is usually quite clear in endemic regions such as Brazil, but it can be challenging to clinicians in nonendemic counties when faced with a patient who has acquired the infection elsewhere. We report two clinical cases of human intraoral myiasis and discuss the diagnosis and treatment of this condition. Two men, ...
