Microbiological changes in the nests of leaf-cutting ants fed on sesame leaves

The number of bacteria and yeasts occurring in the organic matter inside the nests were determined both in colonies of leaf-cutting ants reared on Eucaliptus alba (control) or Sesamum indicum (experimental). Sesame leaves induce imbalance and nests usually die. In control nests the number of bacteria in newer sponge and in older sponge were similar (3.6 x 105 and 1.4 x 105 CFU/g, respectively) whereas in waste deposit the mean reached 7.3 x 107 CFU/g. The most Probable Number (MPN/g) of yeasts were 2.7 x 104, 1.3 x 105/g and 2.2 x 104 for newer sponge, older sponge and waste deposit, respectively. Using material from older sponge for comparison, the number of bacteria and yeasts reared on sesame leaves showed significant differences. The number of bacteria was 3.3 x 107 CFU/g, a value close to that found in waste deposit of normal (control) nests, whereas the number of yeasts was 6.7 x 105/g. These changes in microbial populations due to the effect of sesame leaf uptake could be a significant factor in nest imbalance and mortality when leaf-cutting ants are consuming toxic plants.

Detection of infectious bronchitis virus in experimentally infected chickens by an antigen-competitive ELISA

An antigen-competitive enzyme-linked immunosorbent assay (Ag-C-ELISA) was developed for the detection of infectious bronchitis virus (IBV) antigens, M41 strain, in tissues from experimentally infected chickens, or in allantoic fluid harvested from inoculated embryonated eggs. The detection limit of IBV in the Ag-C-ELISA was 104.1 median embryo infective doses (EID50)/well. Tracheal and lung samples from chickens vaccinated with 102.5 EID50 of live attenuated infectious bronchitis (H120) vaccine were negative in the direct detection Ag-C-ELISA. The results indicate that the Ag-C-ELISA has the potential to detect IBV, either directly in tissue samples or when combined with the passage of material in embryonated eggs, thereby constituting an alternative method for the diagnosis of IBV.

A radiation hybrid map of river buffalo (Bubalus bubalis) chromosome 1 (BBU1)

The largest chromosome in the river buffalo karyotype, BBU1, is a submetacentric chromosome with reported homology between BBU1q and bovine chromosome 1 and between BBU1p and BTA27. We present the first radiation hybrid map of this chromosome containing 69 cattle derived markers including 48 coding genes, 17 microsatellites and four ESTs distributed in two linkage groups spanning a total length of 1330.1 cR(5000). The RH map was constructed based on analysis of a recently developed river buffalo-hamster whole genome radiation hybrid (BBURH5000) panel. The retention frequency of individual markers across the panel ranged from 17.8 to 52.2%. With few exceptions, the order of markers within linkage groups is identical to the order established for corresponding cattle RH maps. The BBU1 map provides a starting point for comparison of gene order rearrangements between river buffalo chromosome 1 and its bovine homologs. Copyright (C) 2007 S. Karger AG, Basel.

Measurement of the t(t)over-bar production cross section in p(p)over-bar collisions at root s=1.96 TeV using kinematic characteristics of lepton plus jets events

We present a measurement of the top quark pair (t (t) over bar) production cross section (sigma(t (t) over bar)) in pp collisions at a center-of-mass energy of 1.96 TeV using 230 pb(-1) of data collected by the DO detector at the Fermilab Tevatron Collider. We select events with one charged lepton (electron or muon), large missing transverse energy, and at least four jets, and extract the t (t) over bar content of the sample based on the kinematic characteristics of the events. For a top quark mass of 175 GeV, we measure sigma(t (t) over bar) 6.7(-1.3)(+1.4)(stat)(-1.1)(+1.6)(syst) +/- 0.4(lumi) pb, in good agreement with the standard model prediction.

On codimensions k immersions of m-manifolds for k=1 and k=m-2

Let us consider M a closed smooth connected m-manifold, N a smooth ( 2m-2)-manifold and f: M -> N a continuous map, with m equivalent to 1( 4). We prove that if f*: H(1)(M; Z(2)) -> H(1)(f(M); Z(2)) is injective, then f is homotopic to an immersion. Also we give conditions to a map between manifolds of codimension one to be homotopic to an immersion. This work complements some results of Biasi et al. (Manu. Math. 104, 97-110, 2001; Koschorke in The singularity method and immersions of m-manifolds into manifolds of dimensions 2m-2, 2m-3 and 2m-4. Lecture Notes in Mathematics, vol. 1350.

Analgesia pós-operatória para crianças com menos de 1 ano: análise retrospectiva

JUSTIFICATIVA E OBJETIVOS: A dor pós-operatória continua sendo uma das principais complicações pós-operatórias e motivo de desconforto, principalmente em crianças. O objetivo deste estudo foi avaliar o uso de analgésicos desde o término da cirurgia até a alta da sala de recuperação pós-anestésica (SRPA), como medida terapêutica ou profilática, para crianças com menos de 1 ano de idade. MÉTODO: Utilizando o banco de dados do Departamento de Anestesiologia, foi realizada análise retrospectiva, envolvendo o período de janeiro de 2000 a abril de 2001, das anestesias de crianças menores que 1 ano de idade submetidas a procedimentos cirúrgicos diversos, avaliando aspectos relacionados à analgesia pós-operatória. RESULTADOS: No período do estudo, foram anestesiadas 402 crianças menores que 1 ano, sendo que 194 (48,2%) não receberam analgésicos e 208 (51,8%) receberam. Com relação ao uso ou não de analgésicos, foi observado o que se segue: Sem analgésicos: (1) Idade: até 1 mês, 68/99; entre 1 e 6 meses, 53/126; entre 6 meses e 1 ano, 73/177. (2) Peso: 6,7 ± 3,1 kg (3). Sexo: masculino, 106/240; feminino, 88/162. (4) Estado físico ASA: ASA I, 69/187; ASA II, 56/113; ASA III, 46/79; ASA IV, 23/23. (5) Anestesia peridural sacral: 3/4. (6) Tempo de anestesia: 106 ± 32 minutos. (7) Encaminhamento para unidade de terapia intensiva (UTI): 93/119. Uso de analgésicos: (1) Idade: até 1 mês, 31/99; entre 1 e 6 meses, 73/126; entre 6 meses e 1 ano, 104/177. (2) Peso: 9 ± 2,3 kg. (3) Sexo: masculino, 134/240; feminino, 74/162. (4) Estado físico ASA: ASA I, 118/187; ASA II, 57/113; ASA III, 33/79; ASA IV, 0/23. (5) Anestesia peridural sacral: 1/4. (6) Tempo de anestesia: 130 ± 38 minutos. (7) Encaminhamento para UTI: 26/119. Os fármacos empregados para promover analgesia foram: dipirona (60,6%), dipirona + tramadol (25,5%), dipirona + nalbufina (5,3%), tramadol (3,8%), nalbufina (3,8%), meperidina (0,5%) e fentanil (0,5%). CONCLUSÕES: Utilizar analgésicos em crianças desde o término da cirurgia até a alta da SRPA não foi habitual, principalmente nas crianças menores e mais graves e em procedimentos cirúrgicos mais rápidos. O uso de dipirona, isoladamente, ou a associação dipirona/tramadol, foram as drogas analgésicas mais freqüentemente empregadas.
