ISSN: 1365-2044Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Summary The Streamlined Liner of the Pharynx Airway (SLIPA™) is a new inexpensive disposable supraglottic airway designed to seal without the use of an inflatable cuff. It comprises a hollow blow-moulded soft plastic airway shaped to form a seal in the pharynx. Being hollow, liquid entrapment is possible and this may provide effective protection against aspiration. A model silicone rubber pharynx with an ‘oesophageal’ tube for injecting volumes of regurgitant liquid was designed to evaluate the SLIPA™ and the standard and ProSeal laryngeal mask airways during positive-pressure ventilation. A linear relationship between the volume ‘regurgitated’ and the volume ‘aspirated’ was found with the laryngeal mask airway and the ProSeal laryngeal mask airway with the drainage tube clamped. Both the ProSeal laryngeal mask airway with an open drainage tube and the SLIPA™, but not the standard laryngeal mask airway, provided effective protection against ‘aspiration’ during positive-pressure ventilation using the model. In a clinical study, 120 patients were randomly allocated to receive controlled ventilation of the lungs via the standard laryngeal mask airway or the SLIPA™. Both devices were equally easy to insert and satisfactory for airway management.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-2044Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Untested assumptions have been made with regard to functional dead space in facemasks, filters and breathing systems used in children for the administration of inhalation anaesthesia. Total functional dead space was measured in various combinations of this equipment applied to a spontaneous ventilation lung model with parameter settings appropriate for infants of 7–8 kg. We found that functional dead space was too large to allow for spontaneous ventilation of the lungs when a breathing filter was fitted. There was minimal relationship between size of the facemask and functional dead space; however, the provision of 22-mm female inlets to facemasks achieved proportionately less functional dead space than with 15-mm male inlets. Regardless of the apparatus used and the magnitude of the dead space, the leak induced when a poorly fitting facemask was used dramatically reduced the dead space of the breathing system – to near optimal conditions – by moving the alveolar gas elimination point to within the facemask itself.Type of Medium: Electronic ResourceURL: -

Uniformity in EAG response between the sexes was observed for most test compounds. Only 10 volatiles, of the 44 nectarine volatiles tested, elicited significantly different EAG responses between the sexes. No correlation was observed between the magnitude of antennal responsiveness and the concentration of a particular volatile in the headspace odor of ripe nectarines. The most abundant (‘major’) nectarine volatiles were among the least EAG stimulatory compounds tested. And certain ‘minor’ and ‘trace’ volatiles were the most potent compounds in eliciting EAGs. Moreover, the magnitude of antennal response to a nectarine volatile was related to the functional-group, chain-length, and unsaturation of the compound. The degree of potency of the compounds was as follows: six-carbon unsaturated aldehydes and alcohols≥methyl and ethyl hexanoates and octanoates≥hexenyl acetates and monoterpenes〉shorter chain-length acetates and alcohols〉lactones. Unsaturated aldehydes, alcohols, and acetates generally elicited larger EAGs than their saturated analogs, with the (E)-2-isomers being the most potent isomeric configurations. In addition, medfly antennae exhibited ‘long recovery’ periods (i.e., 〉10 sec.) for the EAG tracings to return to baseline potential after stimulations with certain classes of compounds, e.g., C6 to C8 acid esters, monoterpenes, and hexen-1-ols. The potential adaptiveness to medflies for selective sensitivity to these volatiles is discussed.Type of Medium: Electronic ResourceURL: -

Dual-choice competitive assays were run to establish a baseline response of virgin females to live male pheromone, individual components, and an ensemble of all five compounds alone (air control) and competitively against one another. Approximately 50% of the females released in the tunnel were captured on leaf models emitting pheromonal odors from five live males. Over 37% of released females responded to an ensemble of five major identified components presented in individual capillaries. Response of females to individual components was less than 10%. Competitive assays showed the live male-produced pheromone to be more attractive than either the five major component ensemble (FMCE) or individual components. Further research is likely to identify other male-produced compounds with pheromonal activity that could improve development of a pheromone-based trap for monitoring Mediterranean fruit fly populations.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-1561Keywords: Coleoptera ; Scolytidae ; bark beetle ; Ips paraconfusus ; aggregation pheromone ; enantiomer ; electrophysiology ; electroantennogram ; interruption ; allomoneSource: Springer Online Journal Archives 1860-2000Topics: BiologyChemistry and PharmacologyNotes: Abstract Antennae of male and femaleIps paraconfusus were equally and highly sensitive to their male-produced, multicomponent aggregation pheromone. Female and male antennae were highly sensitive to the pheromonal component, (S)-(−)-ipsenol, but essentially insensitive to its antipode, (R)-(+)-ipsenol. Further, female and male antennae were more sensitive to the pheromonal component, (S)-cis-verbenol, than to its antipode, (R)-cis-verbenol. Dramatic sexual dimorphism in chiral sensitivity to the ipsdienol enantiortiers was found, with female antennae being more sensitive to the conspecific pheromonal enantiomer, (S)-(+)-ipsdienol, and male antennae being more sensitive to the antipode, (R)-(−)-ipsdienol. Since (R)-(−)-ipsdienol is the principal pheromone of CaliforniaIps pini and interruptsI. paraconfusus aggregation, male antennae appear to be more sensitive to an interspecific allomone than a conspecific pheromone. Of the conspecific pheromonal enantiomers, both male and female antennae were most sensitive to (S)-(+)-ipsdienol, intermediately sensitive to (S)-(−)-ipsenol, and least sensitive to (S)-cis-verbenol. However, when enantiomeric sensitivities were compared to the estimated concentrations of these components in the natural pheromone, (S)-(~)-ipsenol tended to equal or approach the potency of (S)-(+)-ipsdienol as an antennal stimulant, while antennal responsiveness to (S)-cis-verbenol was dramatically less than for the other two pheromonal components. The behavioral implications of such physiological sensitivities are discussed in regard to perception of multicomponent synergistic pheromones and the relative efficacy of each component as an orientation cue.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-1561Keywords: Coleoptera ; Scolytidae ; bark beetle ; Ips paraconfusus ; pheromone ; enantiomer ; electrophysiology ; electroantennogram ; interruption ; allomoneSource: Springer Online Journal Archives 1860-2000Topics: BiologyChemistry and PharmacologyNotes: Abstract The antennal sensitivities of both male and femaleIps paraconfusus were found generally to be greatest for conspecific aggregation pheromones (ipsdienol, ipsenol); intermediate for an additional conspecific pheromone (cis-verbenol), an aggregation synergist (2-phenylethanol), and pheromones/allomones of sympatric species (trans-verbenol, verbenone, and frontalin); and lowest for both host terpenes (alpha-pinene and myrcene) and other bark beetle-produced odorants (exo-brevicomin and linalool). Of the enantiomeric compounds tested, antennae of both sexes did not differ in sensitivity between thetrans-verbenol enantiomers at low dosage levels; but at higher dosages, the conspecific-produced enantiomer, (1R,4S,5R)-(+)-trans-verbenol, elicited larger mean EAG responses than its antipode, (1S,4R, 5S)-(−)-trans-verbenol. At the mid-dosage range, female antennae tended to be slightly more responsive to (S)-(−)-verbenone than to (R)-(+)-verbenone, while male antennae were equally responsive to stimulations by either verbenone enantiomer. In field bioassays there was a large and significant reduction in trap catches ofI. paraconfusus on traps where the (S)-(−)- or (R)-(+)-enantiomers of verbenone were evaporated beside logs containing boring conspecific males. Only when the (S)-(−)-enantiomer of verbenone was evaporated beside logs containing boring males did the sex ratio ofI. paraconfusus trapped shift from female-dominated to male-dominated attraction. Thus both physiological and behavioral data suggest a differential chiral sensitivity of female beetles for the verbenone enantiomers. The relative sensitivities between different chiral compounds derived from one or the other of the common precursoral host terpenes, (S)-(−)- and (R)-(+)alpha-pinene or myrcene, are discussed.Type of Medium: Electronic ResourceURL: -

Los dos sistemas fueron el tradicional en pastoreo comunal (puestos ganaderos), y el de pastoreo en ranchos con división de potreros. El porcentaje de partos, el peso de los terneros a los siete meses de edad, la mortalidad en animales jovenes y el crecimiento hasta los 18 meses en pastoreo comunal fueron respectivamente 46·4 por ciento, 122·5 kg, 10·2 por ciento y 88·5 kg. Los valores correspondientes para el ganado en ranchos con división de potreros fueron 74·0 por ciento, 177·4 kg, 8·5 por ciento y 105·8 kg. Estos resultados indican estimativos de productividad general de 51 kg y 120 kg en terneros en crecimiento por vaca año y 86 kg y 188 kg en terneros de 18 meses de edad por vaca año para el ganado en pastoreo comunal y en ranchos respectivamente.Notes: Summary A comparison of productivity over a 4-year period from indigenous type beef cattle under two production systems in Botswana is reported. The two systems are: the traditional system on unenclosed communal grazing (cattle post) and ranching within fenced paddocks. Calving percentages, 7-month old calf weight, calf mortality and post-weaning growth to 18 months of age under cattle post conditions were 46·4 per cent, 122·5 kg, 10·2 per cent and 88·5 kg respectively. Corresponding figures for cattle on the fenced ranches were 74·0 per cent, 177·4 kg, 8·5 per cent and 105·8 kg. These results indicate overall productivity estimates of 51 and 120 kg of weaner calf per cow per year and 86 and 188 kg of 18-month old calf per cow per year for the cattle post and fenced ranch respectively.Type of Medium: Electronic ResourceURL: -

The modification of the standard Gow rotating-trap-array, cage olfactometer to allow a single source of natural pheromonal odor to be delivered equally and simultaneously to a number of traps greatly increased trapping efficacy (64% capture rate) and ability to resolve odor preference discrimination by female flies. In olfactometer cage bioassays, responding female medflies expressed preferences in attraction to male odor augmented with either synthetic intermediate or minor components over male odor alone. In dual-choice flight-tunnel bioassays, the minor blend enhanced the attractiveness of both the natural male odor and its synthetic major components. Moreover, the minor blend, when presented together with the synthetic major components, comprised an artificial pheromonal lure competitive for the first time with the natural male odor in attraction of virgin female medflies.Type of Medium: Electronic ResourceURL: -

Published 1980Staff ViewISSN: 1573-1561Keywords: Scolytidae ; bark beetle ; Ips pini ; pheromone ; ipsdienol ; enantiomer ; interruption ; allomoneSource: Springer Online Journal Archives 1860-2000Topics: BiologyChemistry and PharmacologyNotes: Abstract Air containing volatile compounds from around maleIps pini boring in ponderosa pine logs from California was condensed, fractionated by GC, and assayed in the laboratory and field. The only fraction that showed consistent activity in laboratory assays contained a single compound identified as ipsdienol (2-methyl-6-methylene-2,7-octadien-4-ol). Synthetic racemic ipsdienol showed no activity in either the laboratory or field. However, (−)-ipsdienol, the naturally occurring enantiomer, was attractive toI. pini in the laboratory and field, whereas (+)-ipsdienol interrupted the response ofI. pini to a natural source of attraction in field tests. (−)-Ipsdienol is a major component of the attractant pheromone of this species, since its level of activity in laboratory assays was quantitatively comparable to that of the condensed volatiles, and it was as attractive as maleI. pini boring in ponderosa pine in the field. (+)-Ipsdienol is a component of the pheromone of the competing species,I. paraconfusus.Type of Medium: Electronic ResourceURL: -

I. pini from California and New York equally inhibit the response ofI. paraconfusus to maleI. paraconfusus. Ipsenol, one component of the attractant pheromone ofIps paraconfusus, inhibits attacks byIps pini on ponderosa pine logs baited with maleI. pini. The concentration of ipsenol used appears to be critical for effective suppression of attacks.Type of Medium: Electronic ResourceURL:
