The lipophilic opioids: Fentanyl, alfentanil, sufentanil and remifentanil

discusses fentanyl, alfentanil, sufentanil, and remifentanil which are synthetic opioid analgesics with high affinity for the mu opioid receptor. They have been widely adopted in anaesthetic practice for various surgical procedures (e.g. in cardiac surgery) and for long-term analgesia and sedation. Important pharmacokinetic differences between these analgesics have been described, and this chapter addresses how the pharmacokinetic profile of each analgesic is affected by many factors, including patient age, plasma protein content, acid–base balance status, cardiopulmonary bypass, changes in hepatic blood flow, and the co-administration of other drugs which compete for plasma protein carriers and metabolic pathways, although their profile is not significantly affected by renal insufficiency or compensated hepatic dysfunction, which has major clinical implications.

Foods of pigeons and doves in fragmented landscapes of subtropical eastern Australia

We report dietary items of pigeons and doves from northern New South Wales and southern Queensland, obtained from opportunistic sampling of the gut contents of dead birds and observing foraging birds. Most records were from fragmented rainforest habitats, which now support abundant invasive fleshy-fruited plants. The fruits and seeds of invasive plants, particularly Camphor Laurel Cinnamomum camphora, formed the dominant food of several of the species sampled, although in some cases these birds appear to destroy most of the ingested seeds in the gizzard, thereby not contributing to weed dispersal. We also describe the first records of White-headed Pigeons Columba leucomela eating flowers and Brown Cuckoo-Doves Macropygia amboinensis eating flower buds. Camphor Laurel, via flowers, green and ripe fruits, and seeds, provided food for White-headed Pigeons in the Goolmangar district of New South Wales throughout the entire year. Seventy percent of the plant species whose fruits and seeds were recovered from the gut had not previously been recorded as food items for those bird species, illustrating how little is known about the diets of pigeons and doves in fragmented Australian landscapes.

Estudio sobre peligro aviario: Análisis del riesgo de impactos entre aves y aeronaves en el Aeropuerto Internacional Augusto C. Sandino, Managua, Nicaragua

El peligro aviario es el riesgo de coliciones entre aves y aeronaves. Para reducir ese peligro es necesario entender la naturaleza de las aves que habitan dentro y alrededor del aeropuerto y clasificarlas numericamente en base a la peligrosidad que representan, conociendo a la vez las estaciones del año, los meses del año, horas del día, condiciones climáticas, focos de atracción (cobertura, alimentación y agua) que incrementan la abundancia y la riqueza de aves en las áreas aeroportuarias. Para obtener la información se seleccionaron dos sitios de observación: uno en las áreas verdes alrededor de la pista de aterrizaje, con el objetivo de registrar las especies de aves hacen uso de este sitio permanente o temporalmente, y otro en la torre de control, para determinar rutas de aves de mayor peso, gregarias y de alto vuelo en un radio de 3000 m con centro en la torre de control. Las especies observadas con mayor frecuencia en la pista de aterrizaje fueron: Hirundo rustica, Quiscalus mexicanus, Molothrus aeneus, Columbina talpacoti y Columba livia. Desde la torre de control se observaron con mayor frecuencia: Coragyps atratus, Zenaida asiatica, Molotrus aeneus y Quiscalus mexicanus. En la pista de aterrizaje y desde la torre de control la abundancia y riqueza de aves no varió significativamente a lo largo dlos meses del año. En la pista de aterrizaje la abundancia incrementa significativamente en el período seco en horarios de 06:00-07:00 am, principalmente por la presencia de Q. mexicanus y H. rustica. La riqueza en el periodo seco y la abundancia y riqueza en el período lluvioso no varió significativamente. Desde la torre de control no se registraron incrementos significativos de la abundancia y riqueza de aves en el período seco, pero si de la abundancia en el período lluvioso, con alzas a las 11:00 y 13:00, principalmente por la mayores actividades de la especie C. atratus a esas horas. La abundancia de aves en la pista de aterrizaje dependió de las condiciones climáticas, aumentando al aumentar la precipitación y la nubosidad y reduciéndose al aumentar la velocidad del viento y la temperatura. La actividad de las aves observadas desde la torre de control no varió significativamente con las variaciones climáticas diarias. Las especies que hacen mayor uso del enmallado perimetral del aeropuerto para perchar fueron: Passers domesticus, Columbina talpacoti, Tyrannus melancholicus, Crotophaga sulcirostris y Tyrannus forficatus. Los sitios preferidos para anidación dentro del aeropuerto fueron árboles de Almendra ( Terminalia catapa ), Mango ( Manguifera indica ) y dentro del las instalacones del cuerpo de Bomberos, torre de control y los hangares. Se concluye que C. atratus y Q. mexicanus son las especies que más peligro representan para la aviación, seguidas en menor escala de C. livia , C. talpocati, H. rustica y M. aeneus. Los sectores norte, oeste y una parte del sector sur del aeropuerto son áreas de mayor riesgo aviario por una mayor frecuencia de observación de C. atratus en esa zona. La especie Q. mexicanus esta distribuida principalmente en el sector sureste. Las fuentes de atracción para las aves van desde sitios ideales para hábitat, refugio, anidación y perchaje hasta fuente de alimentos que incluyen vegetales, insectos, vertebrados, basureros y mataderos.

Breeding populations of seabirds in California, 1989-1991. Volume I - population estimates

In 1989-1991, the U.S. Fish and Wildlife Service surveyed breeding populations of seabirds on the entire California coast. This study was sponsored by the Minerals Management Service in relation to outer continental shelf oil and gas leasing. At 483 nesting sites (excluding terns and skimmers in southern California), we estimated 643,307 breeding birds of 21 seabird species including: 410 Fork-tailed Storm-petrel (Oceanodroma furcata); 12,551 Leach's Storm-petrel (O. leucorhoa); 7,209 Ashy Storm-petrel (O. homochroa); 274 Black Storm-petrel (O. melania); 11,916 Brown Pelican (Pelecanus occidentalis); 10,037 Double-crested Cormorant (Phalacrocorax auritus); 83,394 Brandt's Cormorant (P. penicillatus); 14,345 Pelagic Cormorant (P. pelagicus); 888 Black Oystercatcher (Haemotopus bachmani); 4,764 California Gull (Larus californicus); 61,760 Western Gull (L. occidentalis); 2,838 Caspian Tern (Sterna caspia) (excluding southern California); 3,550 Forster's Tern (S. forsteri) (excluding southern California); 272 Least Tern (S. albifrons) (excluding southern California); 351,336 Common Murre (Uria aalge); 15,470 Pigeon Guillemot (Cepphus columba); 1,821 Marbled Murrelet (Brachyramphus marmoratus); 1,760 Xantus' Murrelet (Endomychura hypoleuca); 56,562 Cassin's Auklet (Ptychoramphus aleuticus); 1,769 Rhinoceros Auklet (Cerorhinca monocerata); and 276 Tufted Puffin (Fratercula cirrhata). The inland, historical or hybrid breeding status of American White Pelican (P. erythrorynchus), American Oystercatcher (H. palliatus), Heermann's Gull (L. heermanni), Ring-billed Gull (L. delawarensis), Glaucous-winged Gull (L. glaucescens) and Black Tern (Chlidonias niger) are discussed. Estimates for Gull-billed Tern (S. nilotica), Royal Tern (S. maxima), Elegant Tern (S. elegans) and Black Skimmer (Rhynchops niger) will be included in the final draft of this report. Overall numbers were slightly lower than reported in 1975-1980 surveys (summarized in Sowls et al. 1980. Catalog of California seabird colonies. U.S. Dept. Int., Fish Wildl. Serv., Biol. Serv. Prog., FWS/OBS 37/80). Recent declines were found or suspected for Fork-tailed Storm-petrel, Leach's Storm-petrel, White Pelican, Black Tern, Caspian Tern, Least Tern, Common Murre and Marbled Murrelet. Recent increases were found or suspected for Brown Pelican, Double-crested cormorant, California Gull, Western Gull, Forster's Tern and Rhinoceros Auklet. Similar numbers were found for other species or trends could not be determined without additional surveys, studies and/or more in-depth comparisons with previous surveys. The status of terns and skimmers in southern California has not yet been finalized.

Manifestations of heavenly light and fire and the construction of a saint: sanctity, mission and salvation in Adomnán's Vita Columbae

This thesis examines the late seventh-century Latin Life of Columba (Vita Columbae) in a context sympathetic to the spiritual aims and formative intellectual background of its author, Adomnán of Iona. It argues that the Vita Columbae is a sophisticated work, shaped by Adomnán’s spiritual and theological concerns. This sophistication is revealed by a forensic examination of Adomnán’s representation of Columba’s sanctity through a series of miracles, in particular, miracle stories depicting divine manifestations of fire and light. This thesis considers the form and function of these miracle stories in the context of biblical, patristic and medieval interpretations of their archetypes, towards revealing the underlying influence of scriptural, hagiographical and monastic models of sanctity. Chapter one evaluates the function of the Vita Columbae, and outlines the core themes of sanctity which pervade the work, by considering the technical terminology and literary devices found in the opening prefaces in the context of the wider monastic tradition. Chapter two examines Adomnán’s use of biblical models of sanctity to establish Columba’s sanctity, and their relationship between these models and certain miraculous episodes in the Vita Columbae. Chapter three investigates Adomnán’s description of the Holy Spirit as an illuminating fire, and its significance for his portrayal of the saint, by means of a forensic examination of biblical, exegetical and hagiographical treatments of the image. Chapter four examines the missiological, soteriological and providential elements contributing to Adomnán’s portrayal of Columba’s sanctity, as conveyed through the presence of biblical models, particularly the image of the column of fire. Chapter five establishes the influence of monastic examinations of the contemplative life on Adomnán’s portrayal of Columba’s sanctity, and shows how that sanctity is confirmed in terms of his ability to contemplate divine light.

An Gaelaras, by O'Donnell and Tuomey:The Building blocks of Language: Review by Rick LeVert and Tarla MacGabhann

The opening of An Gaelaras - the Irish language cultural centre in Derry designed by O'Donnell + Tuomey - is the most significant architectural addition to the symbolic landscape of the Walled City in recent times. It marks nothing less than a physical re-surfacing and a normalisation of the Irish language in this long fragmented city. This alone places An Gaelaras in a delicate historical arc that spans over 1500 years of architectural heritage and links it with the now invisible ruins of St Columba's original 6th century monastery.

Using an individual-based model to select among alternative foraging strategies of woodpigeons: data support a memory-based model with a flocking mechanism

Population modelling is increasingly recognised as a useful tool for pesticide risk assessment. For vertebrates that may ingest pesticides with their food, such as woodpigeon (Columba palumbus), population models that simulate foraging behaviour explicitly can help predicting both exposure and population-level impact. Optimal foraging theory is often assumed to explain the individual-level decisions driving distributions of individuals in the field, but it may not adequately predict spatial and temporal characteristics of woodpigeon foraging because of the woodpigeons’ excellent memory, ability to fly long distances, and distinctive flocking behaviour. Here we present an individual-based model (IBM) of the woodpigeon. We used the model to predict distributions of foraging woodpigeons that use one of six alternative foraging strategies: optimal foraging, memory-based foraging and random foraging, each with or without flocking mechanisms. We used pattern-oriented modelling to determine which of the foraging strategies is best able to reproduce observed data patterns. Data used for model evaluation were gathered during a long-term woodpigeon study conducted between 1961 and 2004 and a radiotracking study conducted in 2003 and 2004, both in the UK, and are summarised here as three complex patterns: the distributions of foraging birds between vegetation types during the year, the number of fields visited daily by individuals, and the proportion of fields revisited by them on subsequent days. The model with a memory-based foraging strategy and a flocking mechanism was the only one to reproduce these three data patterns, and the optimal foraging model produced poor matches to all of them. The random foraging strategy reproduced two of the three patterns but was not able to guarantee population persistence. We conclude that with the memory-based foraging strategy including a flocking mechanism our model is realistic enough to estimate the potential exposure of woodpigeons to pesticides. We discuss how exposure can be linked to our model, and how the model could be used for risk assessment of pesticides, for example predicting exposure and effects in heterogeneous landscapes planted seasonally with a variety of crops, while accounting for differences in land use between landscapes.

Substituição do farelo de soja pelo de guandu na alimentação de frangos de corte

The objective of this work was to evaluate the nutritive value of pigeon pea meal (PPM) with methionine substituting soybean meal (SM) in diets for 1-28 day-old broiler chicks. The experimental design was that of random blocks, in a 3 × 3 factorial scheme with three substitution levels - 15,30 and 45% - and three methionine supplementation levels in relation to the requirements, that is: 100, 66 and 33%, with four repetitions. It was found that PPM treated for 20 minutes at 100°C substituted up to 30% of the SM, even without methionine supplementation, in relation to liveweight (p<0.01), to food conversion and to the efficiency of utilization of metabolizable energy and to protein (p<0.05). At the 66% level of methionine supplementation, the same results as for these parameters were obtained at all of the levels of substitution of SM by PPM. The 30% or 45% substitution of SM protein by that of PPM affected (p<0.01) the efficiency of methionine utilization. The sulphur amino acid utilization efficiency was affected (p<0.01) beginning at 66% methionine supplementation in the diets.
