Se desarrolló un protocolo de propagación in vitro a partir de meristemos florales para Heliconia bihai cv. Lobster Salmón. Para el efecto se establecieron 250 yemas florales en diferentes tiempos utilizando NaClO al 1% durante 20 min. El medio de establecimiento Murashige y Skoog con mejores resultados fue BAP (2 mg/lt, AIA (1 mg/lt y 0.1 g/lt de L-cisteína. La mayor produccion de brotes en multiplicación se obtuvo con 6 mg/lt de BAP y con un subcultivo posterior en medio con 2 mg/lt de BAP y 0.5 mg/lt de AIA, alcanzando una tasa de multiplicación de tres nuevas yemas. El enraizamiento de las plántulas in vitro se logró con 1.3 mg/lt de AIA. La aclimatación en vivero fue 92% de supervivencia. Se realizó un análisis de varianza (Anova y un test de Tukey para las variables evaluadas las cuales mostraron diferencias estadísticas en cada fase. La propagación in vitro de heliconias a partir de yemas florales requiere mayor tiempo en la fase de establecimiento y multiplicación, no obstante permite mayores porcentajes de supervivencia y una menor contaminación, ofreciendo material de siembra de diferentes especies de esta planta de interés comercial.

Formation of a quasi-symmetrical mu 3-carbonato-bridged self-assembled heteromolecular triangle of Ni(II), [(mu 3-CO 3){Ni 2(salmeNH) 2(NCS) 2}{Ni(salmeNH 2) 2].Et 2O.H 2O (HsalmeNH = 2-[(3-methylamino-propylimino)-methyl]-phenol) involves atmospheric CO 2 uptake in a neutral medium, by spontaneous self-reorganization of the starting mononuclear Ni(II)-Schiff-base complex, [Ni(salmeNH) 2]. The environment around Ni(II) in two of the subunits is different from the third one. The starting complex, [Ni(salmeNH) 2], and one of the possible intermediate species, [Ni(salmeNH 2) 2(NCS) 2], which has a very similar coordination environment to that in the third Ni(II) center, have been characterized structurally. A plausible mechanism for the formation of such a triangle has also been proposed. The compound shows a very strong antiferromagnetic coupling. Fit as a regular triangular arrangement gave J = -53.1, g = 2.24, and R = 1.5 x 10 (-4).

Platt, D J; Sommerville, J S; Gribben, J

1984-01-01

Salmonella typhimurium, resistant only to trimethoprim and sulphamethoxazole, was isolated from the faeces and blood of a chronic alcoholic patient in acute renal failure. The isolates harboured an 18 Md non-conjugative plasmid. He was dialysed peritoneally and treated with ampicillin; four days later there was no clinical improvement and his peritoneal dialysis fluid (PDF) had become infected. Salm. typhimurium was isolated from faeces and PDF. Both isolates were additionally resistant to ampicillin and contained two plasmids (55 Md and 18 Md). Therapy was changed to chloramphenicol and gentamicin was added to the PDF. Two weeks later Salm. typhimurium was again isolated from PDF and faeces. The PDF isolate was unchanged but 4% of the colonies isolated from this faecal specimen were resistant to chloramphenicol and had acquired an additional 62 Md plasmid. From all PDF and faecal specimens two different strains of Escherichia coli and one strain of Klebsiella pneumoniae were isolated which contained plasmids indistinguishable, on the basis of molecular weight and transferable resistance markers, from those acquired by Salm. typhimurium. The transferability of these plasmids in vitro to E. coli K12 and to the patient's initial Salm. typhimurium was studied and the results discussed.

Full Text Available Con el propósito de aportar información para contribuir al desarrollo del cultivo de la trucha café anádroma (Salmo trutta trutta en Chile, también llamada seatrout, en este trabajo se revisan los siguientes aspectos: i características genéticas y origen evolutivo de la trucha café naturalizada existente en el país, ii rendimiento reproductivo bajo condiciones de cautiverio, and iii eficiencia del proceso de esmoltificación, tasa de crecimiento y maduración sexual en agua dulce y agua de mar de la trucha café anádroma. Estos últimos parámetros son particularmente relevantes para una apropiada evaluación de su desempeño bajo condiciones de cultivo intensivo. El análisis de estos aspectos indica que las poblaciones naturalizadas de trucha café en Chile presentan un alto grado de variación genética, junto con un probable origen único (línea filogenética Atlántica, norte de Europa; éstas también presentan un rendimiento reproductivo óptimo, que excede aquel observado en otros salmónidos. Además, el proceso de esmoltificación de la trucha café anádroma es equivalente al observado en salmónidos totalmente anádromos, como el salmón del Atlántico y el salmón coho. Asimismo, con excepción de la maduración precoz, que es más alta que en el salmón del Atlántico, sobre todo en los machos, esta variedad también muestra una favorable tasa de crecimiento y sobrevivencia en agua de mar. Todos estos antecedentes indican que el cultivo de la trucha café anádroma es una alternativa interesante, con potencial para ser incorporada en la salmonicultura nacional.

Full Text Available Some polyunsaturated aldehydes (PUAs such as 2-trans, 4-trans decadenial (A3 have a detrimental effect on the development of copepod sharmful to the salmon industrysuch as Caligus rogercresseyi (sea lice. The purpose of this study was to evaluate the potential use of A3 as a salmon feed ingredient in order to reduce reproduction of Caligus rogercresseyi in infested Atlantic salmon (Salmo salar. The toxicity of A3 was assessed histopathologically for 7 days, using intra-peritoneal injections of different doses (0, 0.24, 0.47, 2.37, 11.86, and 23.71 mg kg-1 in brain, intestine, skin, liver, and muscletissues of Salmosalar at the end of each treatment. The effect of A3 on sea lice was evaluated using 250 Atlantic salmon in an open-flow system of seawater (~13°C. The effect of the dosage in the fish diet was evaluated at two levels (9 mg kg-1, 18 mg kg-1 and considering a control (without A3 for 4, 8, and 12 days, once the sea lice had reached maturity. As a complement, the persistent effect of diluted A3 in sea water (0.5 g L-1 was evaluated at 10, 12, and 14°C for 0, 1, 3, 6, 10, and 15 days; and the maximum persistence was found at 10 days at 10°C. The results showed that the dosages over 0.47 mg kg-1 had no toxic effect on Atlantic salmon, but induced a detrimental effect on Caligus rogercresseyi (reduction of 15% of mature females with a dose of 18 mg kg-1, which could be attributed to alterations in the embryonic development of the sea lice. A3 is a potential supplement in the diet of salmon. However, studies ofits mechanism of action should be undertaken prior to its use.Algunos aldehídos poli-insaturados (PUAs tales como 2-trans, 4-trans decadenal (A3 tienen efecto perjudicial para el desarrollo de copépodos perjudiciales para la industria del salmón, tales como Caligus rogercresseyi (piojo de mar.

In this study, the effects of thermosonication and thermal treatment on Escherichia coli O157:H7 and Salmonella Enteritidis in mango juice were investigated at 50 and 60°C. Besides, nonlethal injury of Salm. Enteritidis after both treatments was also examined. The highest inactivation was attained with thermosonication at 60°C. The inactivation rate was different for both pathogens, and Salm. Enteritidis was found to be more sensitive to thermosonication than E. coli O157:H7. Salmonella Enteritidis was recovered in all treated samples, except those subjected to more than 5-min thermosonication at 60°C. It was found that the introduction of high-intensity ultrasound enhanced the inactivation of pathogens compared to thermal treatment alone. On the other hand, Salm. Enteritidis was detected in a number of samples following incubation in universal pre-enrichment broth, but no growth was detected after incubation in mango juice. Fruit juices are commonly heat treated to inactivate micro-organisms and enzymes. However, excessive heat treatments may result in undesirable changes in juice quality. Treatment by power ultrasound, a nonthermal technology, may be an alternative processing technique to pasteurize fruit juices. This study highlights the effectiveness of thermosonication in inactivating Escherichia coli O157:H7 and Salmonella Enteritidis in mango juice. © 2012 The Society for Applied Microbiology.

As the incidence of multidrug resistance (MDR) Salmonella enterica serotype Typhimurium is increasing, data regarding the antimicrobial interventions and pathogen internalization in marinated meat products are important. This study evaluated the antimicrobial intervention and internalization of Salm. Typhimurium in marinated beef sirloin steaks. Beef bottom sirloin flaps (IMPS #185A; USDA Select) inoculated (10 8  log 10  CFU ml -1 ) with Salm. Typhimurium were sprayed (lactic acid (4%) and buffered vinegar (2%)) prior to vacuum-tumbled marination (0·35% sodium chloride and 0·45% sodium tripolyphosphate) for 30 min. Pathogen presence after antimicrobial spray, vacuum-tumbled marination, and translocation was determined by direct plating on Xylose Lysine Deoxycholate (XLD) agar with tryptic soy agar (TSA) overlay. The data imply varied internalization and antimicrobial susceptibility pattern of Salm. Typhimurium in marinated meat. Lactic acid (4%) spray (P internalization and potential survival of Salmonella spp. in marinated beef products is a major concern. These results highlight the internalization of pathogens in vacuum-tumbled meat products and emphasize the importance of considering these products as nonintact. Similarly, these data confirm the efficacy and utility of interventions prior to vacuum-tumbled marination. Further research is needed to identify additional strategies to mitigate internalization and translocation of pathogens into vacuum-marinated meat products. © 2016 The Society for Applied Microbiology.

This study evaluated the impact of sodium dichloroisocyanurate (5, 10, 20, 30, 40, 50 and 250 mg l(-1) ) in wash water on transfer of Salmonella Typhimurium from contaminated lettuce to wash water and then to other noncontaminated lettuces washed sequentially in the same water. Experiments were designed mimicking the conditions commonly seen in minimally processed vegetable (MPV) processing plants in Brazil. The scenarios were as follows: (1) Washing one inoculated lettuce portion in nonchlorinated water, followed by washing 10 noninoculated portions sequentially. (2) Washing one inoculated lettuce portion in chlorinated water followed by washing five noninoculated portions sequentially. (3) Washing five inoculated lettuce portions in chlorinated water sequentially, followed by washing five noninoculated portions sequentially. (4) Washing five noninoculated lettuce portions in chlorinated water sequentially, followed by washing five inoculated portions sequentially and then by washing five noninoculated portions sequentially in the same water. Salm. Typhimurium transfer from inoculated lettuce to wash water and further dissemination to noninoculated lettuces occurred when nonchlorinated water was used (scenario 1). When chlorinated water was used (scenarios 2, 3 and 4), no measurable Salm. Typhimurium transfer occurred if the sanitizer was ≥10 mg l(-1) . Use of sanitizers in correct concentrations is important to minimize the risk of microbial transfer during MPV washing. In this study, the impact of sodium dichloroisocyanurate in the wash water on transfer of Salmonella Typhimurium from inoculated lettuce to wash water and then to other noninoculated lettuces washed sequentially in the same water was evaluated. The use of chlorinated water, at concentration above 10 mg l(-1) , effectively prevented Salm. Typhimurium transfer under several different washing scenarios. Conversely, when nonchlorinated water was used, Salm. Typhimurium transfer occurred in

In response to a dramatic change in the epidemiology of Salmonella Enteritidis in England and Wales thought to be associated with raw shell eggs, the Health Protection Agency initiated public health investigations to establish the incidence of Salmonella contamination and origin of eggs used by catering premises implicated in outbreaks of Salm. Enteritidis. Between October 2002 and November 2004, 16 971 eggs were sampled and Salmonella were recovered from 3.4%. Salmonella was isolated from 5.5% and 6.3% of Spanish and eggs of unknown origin, respectively, used in catering premises linked to outbreaks, a level significantly higher than that (1.1%) found in nonLion Quality UK eggs sampled. The small sample of UK Lion Quality eggs tested (reflecting their lack of use in premises visited) did not contain Salmonella. Several phage types of Salm. Enteritidis other than phage type 4 (PT 4) were identified with nonUK eggs. Eggs from Spain were implicated as a major source of infection. Eggs were contaminated more frequently with Salmonella when shells were dirty and/or cracked, and stored at above 8 degrees C. The use of Spanish eggs by the catering sector has been identified as a consistent significant factor in many of the outbreaks caused by Salm. Enteritidis nonPT4 in England and Wales during 2002-2004. Advice to caterers and hospitals that raw shell eggs should not be used in food that will either not be cooked or only lightly cooked should be reinforced.

The intersection of the extrinsic hedgehog and WNT/wingless signals with the intrinsic Hox code underpins branching pattern and tube shape diversity in the drosophila airways.

Full Text Available The tubular networks of the Drosophila respiratory system and our vasculature show distinct branching patterns and tube shapes in different body regions. These local variations are crucial for organ function and organismal fitness. Organotypic patterns and tube geometries in branched networks are typically controlled by variations of extrinsic signaling but the impact of intrinsic factors on branch patterns and shapes is not well explored. Here, we show that the intersection of extrinsic hedgehog(hh and WNT/wingless (wg signaling with the tube-intrinsic Hox code of distinct segments specifies the tube pattern and shape of the Drosophila airways. In the cephalic part of the airways, hh signaling induces expression of the transcription factor (TF knirps (kni in the anterior dorsal trunk (DTa1. kni represses the expression of another TF spalt major (salm, making DTa1 a narrow and long tube. In DTa branches of more posterior metameres, Bithorax Complex (BX-C Hox genes autonomously divert hh signaling from inducing kni, thereby allowing DTa branches to develop as salm-dependent thick and short tubes. Moreover, the differential expression of BX-C genes is partly responsible for the anterior-to-posterior gradual increase of the DT tube diameter through regulating the expression level of Salm, a transcriptional target of WNT/wg signaling. Thus, our results highlight how tube intrinsic differential competence can diversify tube morphology without changing availabilities of extrinsic factors.

Inhibition of Salmonella typhi growth using extremely low frequency electromagnetic (ELF-EM) waves at resonance frequency.

Science.gov (United States)

Fadel, M A; Mohamed, S A; Abdelbacki, A M; El-Sharkawy, A H

2014-08-01

Typhoid is a serious disease difficult to be treated with conventional drugs. The aim of this study was to demonstrate a new method for the control of Salmonella typhi growth, through the interference with the bioelectric signals generated from the microbe during cell division by extremely low frequency electromagnetic waves (ELF-EMW-ELF-EM) at resonance frequency. Isolated Salmonella typhi was subjected to square amplitude modulated waves (QAMW) with different modulation frequencies from two generators with constant carrier frequency of 10 MHz, amplitude of 10 Vpp, modulating depth ± 2 Vpp and constant field strength of 200 V m(-1) at 37°C. Both the control and exposed samples were incubated at the same conditions during the experiment. The results showed that there was highly significant inhibition effect for Salm. typhi exposed to 0·8 Hz QAMW for a single exposure for 75 min. Dielectric relaxation, TEM and DNA results indicated highly significant changes in the molecular structure of the DNA and cellular membrane resulting from the exposure to the inhibiting EM waves. It was concluded that finding out the inhibiting resonance frequency of ELF-EM waves that deteriorates Salm. typhi growth will be promising method for the treatment of Salm. typhi infection either in vivo or in vitro. This new non-invasive technique for treatment of bacterial infections is of considerable interest for the use in medical and biotechnological applications. © 2014 The Society for Applied Microbiology.

Whole farm quantification of GHG emissions within smallholder farms in developing countries

International Nuclear Information System (INIS)

Seebauer, Matthias

2014-01-01

The IPCC has compiled the best available scientific methods into published guidelines for estimating greenhouse gas emissions and emission removals from the land-use sector. In order to evaluate existing GHG quantification tools to comprehensively quantify GHG emissions and removals in smallholder conditions, farm scale quantification was tested with farm data from Western Kenya. After conducting a cluster analysis to identify different farm typologies GHG quantification was exercised using the VCS SALM methodology complemented with IPCC livestock emission factors and the cool farm tool. The emission profiles of four farm clusters representing the baseline conditions in the year 2009 are compared with 2011 where farmers adopted sustainable land management practices (SALM). The results demonstrate the variation in both the magnitude of the estimated GHG emissions per ha between different smallholder farm typologies and the emissions estimated by applying two different accounting tools. The farm scale quantification further shows that the adoption of SALM has a significant impact on emission reduction and removals and the mitigation benefits range between 4 and 6.5 tCO 2  ha −1  yr −1 with significantly different mitigation benefits depending on typologies of the crop–livestock systems, their different agricultural practices, as well as adoption rates of improved practices. However, the inherent uncertainty related to the emission factors applied by accounting tools has substantial implications for reported agricultural emissions. With regard to uncertainty related to activity data, the assessment confirms the high variability within different farm types as well as between different parameters surveyed to comprehensively quantify GHG emissions within smallholder farms.

Compiling Data from Geological, Mineralogical and Geophysical (IP/RS Studies on Mahour Deposit, Northwest of Deh-salm, Lut Block

Directory of Open Access Journals (Sweden)

Arash Gorabjeiri Puor

2015-10-01

Full Text Available Introduction The Mahour exploration area is a polymetallic system containing copper, zinc and silver. The mineralization can be seen in two forms of veins and disseminations. This area is structurally within the Lut block, west of Deh-salm Village. Recent exploration work and studies carried out by geologists on this volcanic-plutonic area of Lut demonstate its importance indicating new reserves of copper, gold, and lead and zinc. Several articles have been published on the Mahour deposit in recent years, including work on fluid inclusions (Mirzaei et al., 2012a; Mirzaei et al., 2012b. The present report aims at completion of previous studies on Mahour. During the course of this research, the IP/RS geophysical methods were used to locate the extent and depth of sulfide veins in order to locate drill sites. The IP/RS method has been used extensively worldwide in locating sulfide mineralization at deposits such as Olympic Dam in Australia (Esdale et al., 1987, Hishikari epithermal gold deposit in Kagoshima, Japan (Okada, 1995 and Cadia-Ridgeway copper and gold deposit in New South Wales, Australia (Rutley et al., 2001. Materials and Methods 1. Determination of mineralogy of ore and alteration by examination of 70 thin sections and 45 polished sections. 2. Compilation of geological and mineralization maps of the studied area at a scale of 1:1000. 3. Geological, alteration, mineralization and trace element geochemical studies of 6 drill holes. 4. IP/RS measurements for 2585 points on a rectangular grid with profile intervals of 50 meters and electrode intervals of 20 meters. 5. Interpretation of IP/RS results. Discussion The Mahour area is covered by a volcanic sequence of basalt, andesite, dacite, rhyolite and pyro-clastics. During the Late Eocene through Early Oligocene this volcanic complex was intruded by several diorite and quartz-diorite bodies, which were responsible for mineralization of the area. Mineralized veins hosted by dacite show NNE

management tools and approaches to control the populations avoiding irreversible ecosystem disruptions and social conflictsLos salmonídeos no son nativos del hemisferio sur, y es así que las truchas (arcoiris y café se establecieron en el sur de Sudamérica hace un siglo. La mayoría de los intentos por introducir salmones anádromos falló hasta el establecimiento de la acuicultura en los años ochenta. A partir de 1990, aparentemente debido a escapes de Oncorhynchus tshawytscha (salmón Chinook de cultivo, se están produciendo retornos reproductivos de esta especie en cuencas chilenas y argentinas al sur de los 39º S. En este trabajo se muestra la ocurrencia histórica y espacial de salmón chinook en cuatro cuencas de vertiente Pacífica durante la última década. Nuestro objetivo es establecer el progreso de su establecimiento al tiempo que se proyectan algunos impactos así como alternativas de manejo. En Chile, el muestreo se realizó entre 1995 y 2005 incluyendo los ríos Petrohué, Poicas, Río Negro-Hornopirén, y el Lago Puyehue, en la X Región. En Argentina los ríos muestreados incluyen al Futaleufú, Carrenleufú y Pico. En las cuencas chilenas y argentinas los Chinook reproductivos alcanzaban 73 a 130 cm de largo total encontrándose los más pequeños en el Lago Puyehue donde la población estaría encerrada. En el Río Petrohué, los retornos variaron de año en año alcanzando máximos en 1996 y en el 2004 de hasta 500 kg de pescado en una extensión de 100 m de río. La distribución temporal de juveniles sugiere que principalmente se trata del tipo chinook oceánico ya que migrarían al mar durante el primer año de vida. Como se observa en Petrohué, poblaciones reproductivas de la especie aportarían cantidades relevantes de nutrientes de origen marino tal como ocurre en sus hábitats naturales, produciendo así una importante perturbación a los balances y ciclos naturales en estos sitios.

O sêmen foi coletado semanalmente (1 coleta/macho, diluído com meio centrifugador (1:1 e mantido a 25ºC por 2 horas. Após centrifugação (800 g, 10 minutos, o pélete foi suspenso com meio de congelamento para concentração final de 1 × 10(9 espermatozoides/mL. O sêmen foi envasado em palhetas de 0,5 mL e colocado dentro de tubo de ensaio (17ºC, 35 minutos. Após esse período, as palhetas foram retiradas do tubo e mantidas por 25 minutos, quando foram submetidas a vapor de nitrogênio por 20 minutos e mergulhadas em nitrogênio líquido. Após o descongelamento, o sêmen dos animais alimentados com a ração acrescida de óleo de soja reduziu a motilidade, o vigor, a porcentagem de espermatozoides vivos e o teste hiposmotico. A motilidade média do sêmen após a diluição e durante as etapas do congelamento foi de 85 e 84% para os animais que receberam óleo de salmão e soja, respectivamente. Entretanto, após o descongelamento, a motilidade dos espermatozoides dos animais alimentados com a ração contendo óleo de salmão e soja reduziu para 30 e 24%, respectivamente. O sêmen dos animais tratados com óleo de soja apresentou menor porcentagem de espermatozoides vivos e morfologia normal em comparação aos tratados com óleo de salmão. A suplementação com óleo de salmão na dieta de suínos promove redução das características negativas observadas no sêmen suíno descongelado.The objective of this work was to evaluate the effects of addition of oil and of levels of supplementation of E vitamin on

To detect the prevalence, the seasonal occurrence and distribution of Salmonella serotypes in poultry products and to determine the resistance profile of Salmonella isolates. A total of 96 skin-on chicken carcasses and 30 liver samples were analysed between May 2007 and May 2009 from twenty-two different commercial farm brands found in retail market countrywide. Salmonella was isolated from 38 (39·5%) of 96 chicken carcasses and from 10 (33·3%) of 30 liver samples. Higher isolation rate (60·4%) was observed in carcasses detected during summer (May to October), and lower isolation rate (18·7%) was observed in carcasses detected during winter (November to April); in liver samples, the positive rates were 53·4 and 13·2%, respectively. Twelve serotypes were detected with the serotypes Hadar, Enteritidis and Blockley being the most prevalent at 29·2, 22·9 and 12·5%, respectively. Nine of 11 Salm. Enteritidis isolates occurred during summer. Of 48 isolates, 38 (79%) were resistant to one or more of the antimicrobial agents used. The highest resistance rates were found to the following antimicrobials: streptomycin (64·5%), tetracycline (56·2%), nalidixic acid (39·5%), ampicillin and rifampicin (33·3%). The relatively high Salmonella spp. contamination rates of raw chicken meat and liver have been detected. Salm. Enteritidis isolates peaked in summer, increasing the risk to human health. Antibiotic resistance of Salmonella still remains a threat as resistance plasmids may be extensively shared between animal and humans. The study enabled us to improve the data on the seasonal occurrence of Salmonella and to determine the antimicrobial pattern profile and trends in Salmonella strains isolated from poultry retail products in Greece. © 2012 The Authors.

Since 2010, human salmonellosis outbreaks in the UK have been detected as associated with the consumption of duck eggs. Little data are available on the rate of occurrence of Salmonella in duck eggs. The aim of this study was to investigate the occurrence of Salmonella spp. in duck eggs on sale and from catering in England during 2011, particularly those from small-scale production. All samples were collected independently of human salmonellosis outbreak investigations. Composite samples of 6-10 eggs (shells and contents were examined separately) were examined for the presence of Salmonella spp. using the ISO 6579:2002 method. Salmonella spp. was recovered from two of 145 samples (1·4%). In one sample, Salmonella Typhimurium DT 8 was isolated from the shells while Salm. Typhimurium DT 8 and Salm. Typhimurium DT30 were isolated from the contents. Salmonella Typhimurium DT8 was isolated from the egg shells only in the second contaminated sample. This study provides baseline data for risk assessors, regulators and the food industry and may be helpful in communicating risks associated with the consumption of this product as well as evaluating risk management options to control food safety including vaccination of ducks. Human salmonellosis outbreaks in England and Northern Ireland due to Salmonella enterica serovar Typhimurium definitive phage type (DT) 8 have been identified as associated with the consumption of duck eggs since 2010. This study has shown that Salmonella spp. was detected in 1·4% of ducks egg samples providing baseline data for risk assessors, regulators and the food industry. This may be helpful in communicating risks associated with the consumption of this product as well as evaluating risk management options to control food safety including vaccination of ducks. © 2016 Crown copyright.

Quantitative characterization of nonstructural carbohydrates of mezcal Agave (Agave salmiana Otto ex Salm-Dick).

Science.gov (United States)

Michel-Cuello, Christian; Juárez-Flores, Bertha Irene; Aguirre-Rivera, Juan Rogelio; Pinos-Rodríguez, Juan Manuel

2008-07-23

Fructans are the reserve carbohydrates in Agave spp. plants. In mezcal factories, fructans undergoes thermal hydrolysis to release fructose and glucose, which are the basis to produce this spirit. Carbohydrate content determines the yield of the final product, which depends on plant organ, ripeness stage, and thermal hydrolysis. Thus, a qualitative and quantitative characterization of nonstructural carbohydrates was conducted in raw and hydrolyzed juices extracted from Agave salmiana stems and leaves under three ripeness stages. By high-performance liquid chromatography (HPLC), fructose, glucose, sucrose, xylose, and maltose were identified in agave juice. Only the plant fraction with hydrolysis interaction was found to be significant in the glucose concentration plant. Interactions of the fraction with hydrolysis and ripeness with hydrolysis were statistically significant in fructose concentration. Fructose concentration rose considerably with hydrolysis, but only in juice extracted from ripe agave stems (early mature and castrated). This increase was statistically significant only with acid hydrolysis.

Osmoregulation by trehalose synthesis in Salmonella manhattan after exposure to waste waters.

Science.gov (United States)

Dupray, E; Derrien, A; Pichon, R

1995-03-01

A 24 h period in waste waters improved the subsequent survival of Salmonella in oligotrophic sea water, at 20 degrees C, compared to a direct input control. The main osmoprotective compound accumulated, investigated by 1H-NMR spectroscopy (nuclear magnetic resonance), after 6 d in sea water was trehalose. Taking into account these observations, this paper put forward the following explanation concerning the survival mechanism: (1) stress in waste waters induces the endogenous synthesis of trehalose via the activation of the gene kat F; (2) when exposed to an osmotic stress, two degradative cytoplasmic enzymes are repressed and the bacteria accumulate trehalose which acts as an osmoprotectant. The succession of the two steps enables Salm. manhattan to immediately resist to the high salinity of oligotrophic seawater.

Seeds were submerged in alcohol at 70% for 1 min. and then treated with sodium hypochlorite solution at different concentrations: 0.0; 0.5; 1.0 and 1.5%. After thistreatment, the seeds were washed four times in distillated, deionized and autoclaved water. Seeds were inoculated in MS medium with different concentrations of sucrose (0.0, 2.5, 5.0, 7.5 and 10.0 g L-1. The experimental design was completely randomized in a factorialexperiment 4 x 5, with five replicates for treatments. Contamination, germination and seedling growth were evaluated. The results of the analysis of variance indicate that there were no significant interactions among factors. There was no significance for sucroseconcentrations on contamination but these treatments showed significant differences for seed germination and seedling growth (p . 0.01. At higher sucrose concentrations there was lower germination and smaller seedlings. There were significant differences betweenthe treatments with sodium hypochlorite for all traits analysed (p . 0.01.

Full Text Available This study aimed to determine the physical-chemical quality of fish used in a random sampling of 54 samples of sushi and sashimi tuna and salmon obtained in restaurants with the support of Sanitary Surveillance of the city of Rio de Janeiro from July to August 2011. The temperature were measured at the time of sampling. We carried out physical and chemical tests to determine pH, ammonia, H2S, total volatile bases (TVB, trimethylamine (TMA and histamine. All samples were exposed to inadequate temperature. Only one of the samples was found above the recommended pH value by law. Five were positive for ammonia and two positive results for H2S. The average results of TVB ranged between 9.43 and 12.37 mg N-BVT/100g and the amount of TMA ranged between 0.57 and 0.96 mg N-TMA/100g, being within the recommended standard. The histamine was found in five samples, ranging between 1 and 10 mg/100g. Considering the samples studied, seven (12,96% showed some abnormalities on the evaluated parameters. In conclusion, the consumption of sushi and sashimi can cause risk to consumer health. Therefore, we suggest that a continuous attention from the authorities should be held on this type of food due to their high perishability and risk to public health.

MATERIAL Y METODO: Entre 1986 y 1995 se implementaron Campañas de Información en los laboratorios de Análisis Clínicos de la región andinopatagónica argentina, destinadas a lograr una detección más eficiente de la difilobotriasis, a través de análisis coproparasitológicos. RESULTADOS: Adicionalmente, se confeccionaron planillas destinadas a recoger información sobre las características de la infección, del tratamiento y del paciente. Durante este período se detectaron 13 nuevos casos humanos, por identificación directa del parásito o por la presencia de huevos en materia fecal. Las características de las infecciones responden a las descriptas para el género Diphyllobothrium. CONCLUSIONES: En la región, los salmónidos son los peces predilectos en la pesca deportiva. Estos peces, frecuentemente parasitados con larvas, constituyen la principal fuente de contagio para el hombre al ser consumidos insuficientemente cocidos o ahumados en frío.OBJECTIVE: In view of the amateur fishing practices and the importance of salmonids in the region the study sets out to detect human hosts in the Andean-Patagonian zone. MATERIAL AND METHOD: Information campaigns were carried out by Clinical Analysis Laboratories of Andean Patagonia between 1986 and 1995 to detect diphyllobothriasis more efficiently by means of coproparasitological analysis. RESULTS: Further, forms were prepared for the collection of information about infection, treatment and the characteristics of the human host. During this period 13 new cases were registered either through direct identification of the parasite or through the presence of eggs in the faeces.

Full Text Available En la producción de alevines de salmón de la región de la Araucanía (sur de Chile se presentan importantes eventos de mortalidad aguda sin rasgos patológicos aparentes. El problema se focaliza en ejemplares de 0,2 a 1 g y las causas apuntan a procesos de acidificación del pH del agua y a la presencia de ciertos metales pesados, entre los cuales destaca el aluminio, que alcanza concentraciones más allá de los rangos de tolerancia de los peces. La información científica indica que concentraciones de 5 mg Ca L-1 en el afluente son suficientes para mantener a salvo los peces del efectos tóxico del aluminio. Sin embargo, los problemas en la producción de alevines de salmón indican que se requiere un mayor conocimiento científico y evidencia experimental que soporte el desarrollo de procesos y tecnologías para el tratamiento de los afluentes de las pisciculturas chilenas. En este trabajo se evaluó el efecto de cuatro concentraciones de calcio (0, 5, 10 y 20 mg Ca L-1 sobre la toxicidad aguda de 500 μg Al L-1 en alevines de trucha arcoiris (Oncorhynchus mykiss de 0,1 g en agua de cultivo a pH 5, 6 y 7. El objetivo del trabajo fue determinar la dosis de calcio que reduce la toxicidad aguda de aluminio y los tiempos mínimos de reacción que podrían disponer los piscicultores para tomar medidas preventivas ante una concentración aguda de aluminio en el agua de cultivo. Los resultados indican que antes de 8 h de exposición a una concentración tóxica de aluminio los piscicultores deberían asegurar en el agua de cultivo una dosis superior a 10 mg Ca L-1 y un pH >6 como medida remedial para reducir el efecto de intoxicación aguda causada por aluminio.

Full Text Available We developed an adaptable, transparent tool that can be used to quantify and compare vulnerability to overharvest for wild collected medicinal plants. Subsequently, we are creating a list of the most threatened medicinal plants in temperate North America. The new tool scores species according to their life history, the effects of harvest, their abundance and range, habitat, and demand. The resulting rankings, based on explicit criteria rather than expert opinion, will make it easier to discuss areas of vulnerability and set conservation priorities. Here we present scores for 40 species assessed using the At-Risk Tool and discuss the traits that led to different scores for six example species: echinacea (Echinacea angustifolia DC.

Full Text Available Background: Cross-contamination of foodborne pathogens from undercooked poultry meat to ready-to-eat food has been shown to be responsible for a number of foodborne disease outbreaks. Various studies have indicated that bacterial cross-contamination occurs during food preparation where bacteria present on food contact other surfaces and cause illness. Objectives: This study evaluated the ability of bacteria to survive and cross-contaminate other foods during the preparation of fresh chicken. Salmonella spp. cross-contamination from chicken to cucumber and utensils under various food handling scenarios was determined. Methods: Two scenarios were tested: in scenario 1, cutting board and knife used for cutting chicken without washing step were sampled. In scenario 2, cutting board and knife was washed with tap water separately after cutting chicken, and subsequently used for cutting cucumber. In scenario 1, chicken, cutting board, knife, and hands were sampled, and in scenario 2, cucumber was tested. Fluorescent in situ hybridization (FISH method, using published Salmonella specific gene probes was used for Salmonella detection in samples taken from cross-contamination scenarios. A culture-based detection by Hektoen enteric agar was used for the confirmation of Salmonella species. Results: All the samples analyzed were found to be positive for Salmonella spp. with different contamination levels. These results were further confirmed by culture based method. In scenario 1, Salmonella spp. was detected by Sal-1 and Salm-63 oligonucleotide probes in all four samples (chicken, cutting board, knife and hands. A high contamination level was observed in chicken samples in comparison to samples collected from cutting board, knife and hands. In scenario 2, Salmonella spp. was detected by Sal-1 and Salm-63 oligonucleotide probes in the cucumber with very low contamination level. Salmonella Enterica was also detected by Sal-3 and Sapath-3 in both scenarios but

Germination response of Hylocereus setaceus (Salm-Dyck ex DC: ) Ralf Bauer (Cactaceae) seeds to temperature and reduced water potentials.

2010-02-01

The germination response of Hylocereus setaceus seeds to isothermic incubation at different water potentials was analysed by using the thermal time and hydrotime models, aiming to describe some germination parameters of the population and to test the validity of the models to describe the response of the seeds to temperature and water potential. Hylocereus setaceus seeds germinated relatively well in a wide range of temperatures and the germination was rate limited from 11 to 20 degrees C interval and beyond 30 degrees C until 40 degrees C, in which the germination rate respectively shifts positively and negatively with temperature. The minimum or base temperature (T(b)) for the germination of H. setaceus was 7 degrees C, and the ceiling temperature varied nearly from 43.5 to 59 degrees C depending on the percent fraction, with median set on 49.8 degrees C. The number of degrees day necessary for 50% of the seeds to germinate in the infra-optimum temperature range was 39.3 degrees C day, whereas at the supra-optimum interval the value of theta = 77 was assumed to be constant throughout. Germination was sensitive to decreasing values of psi in the medium, and both the germinability and the germination rate shift negatively with the reduction of psi, but the rate of reduction changed with temperature. The values of base water potential (psi(b)) shift to zero with increasing temperatures and such variation reflects in the relatively greater effect of low psi on germination in supra optimum range of T. In general, the model described better the germination time courses at lower than at higher water potentials. The analysis also suggest that Tb may not be independent of psi and that psi(b(g)) may change as a function of temperature at the infra-otimum temperature range.

Challenges for dynamic energy budget theory. Comment on ;Physics of metabolic organization; by Marko Jusup et al.

Science.gov (United States)

Nisbet, Roger M.

2017-03-01

Jusup et al. [1] provide a comprehensive review of Dynamic Energy Budget (DEB) theory - a theory of metabolic organization that has its roots in a model by S.A.L.M Kooijman [2] and has evolved over three decades into a remarkable general theory whose use appears to be growing exponentially. The definitive text on DEB theory [3] is a challenging (though exceptionally rewarding) read, and previous reviews (e.g. [4,5]) have provided focused summaries of some of its main themes, targeted at specific groups of readers. The strong case for a further review is well captured in the abstract: ;Hitherto, the foundations were more accessible to physicists or mathematicians, and the applications to biologists, causing a dichotomy in what always should have been a single body of work.; In response to this need, Jusup et al. provide a review that combines a lucid, rigorous exposition of the core components of DEB theory with a diverse collection of DEB applications. They also highlight some recent advances, notably the rapidly growing on-line database of DEB model parameters (451 species on 15 August 2016 according to [1], now, just a few months later, over 500 species).

Extraction of GEN at Q² = 1 (GeV/c)² from Measurements of polarized He(pol. e, e')

Energy Technology Data Exchange (ETDEWEB)

Jin, Ge [Univ. of Virginia, Charlottesville, VA (United States)

2011-05-01

The neutron electric form factor, GEN , is extracted for the first time at Q² = 1 (GeV/c)² from polarized ³$\\vec{He}$ ($\\vec{e}$ ,e ') measurements in Hall A at Jefferson Lab. By getting the ratio of asymmetries in longitudinal and transverse quasi-elastic ³$\\vec{He}$($\\vec{e}$,e ' ), the electric and magnetic contributions can be separated. The proton and neutron contributions to the ³ He quasi-elastic response functions are calculated in PWIA by Salme? et al., and the neutron electric form factor can be extracted. This method of inclusive scattering becomes feasible for the first time due to the falloff of the other form factors at high Q² while G$n\\atop{E}$ keeps increasing in units of the dipole form factor. Approximately, 20% uncertainty is achieved in the extraction largely contributed by the statistical uncertainties from 3 days of data-taking. All aspects of the measurement will be discussed in this thesis including theoretical model, experiment setup and the details in the analysis.

Por lo anterior, se estableció una multiplicación y crianza de cochinilla silvestre, proveniente de la zona árida del norte de México para caracterizarla, utilizando como hospedero a Opuntia megacantha Salm Dyck. Los resultados indican que la especie silvestre pertenece al género-especie Dactylopius opuntia. Se determinó la presencia de partenogénesis en hembras. La duración de los estadios biológicos depende del sexo del insecto; el adulto hembra permaneció durante 38.4 días y 4.2 días para machos, los primeros estadios ninfales fueron similares en duración (18.1-19.8 días. El ciclo biológico de las hembras fue de 77 días mientras que el de los machos fue de 43 días. Para las hembras se estimó un periodo de preoviposición de 18.8 días, manteniéndose en oviposición durante 21 días con un promedio de 131 insectos por hembra. La proporción sexual hembras: machos fue 1:1. El tipo de reproducción fue predominantemente sexual, aunque hubo hembras partenogénicas.

Full Text Available La relación bidireccional de influencia que la acuicultura establece con el ambiente en el cual se desarrolla determina límites al crecimiento de esta actividad económica en Chile. Esto se ha traducido tanto en restricciones técnicas, como en conflictos ambientales y sociales. La creciente demanda de nuevos productos quimioterapéuticos y su consecuente vertido en ambientes acuáticos es considerado uno de los principales problemas ambientales que enfrenta la industria del salmón en Chile. Sin embargo, poco se sabe acerca de los efectos que ejercen estas sustancias sobre especies no objetivo y, en general, sobre la estructura y función de los ecosistemas expuestos. Mediante la aplicación de teoría y métodos de ecología contemporánea, el trabajo aquí presentado busca contribuir oportunamente al desarrollo de una metodología que permita reducir el nivel de incertidumbre asociado a la evaluación de riesgo ambiental de productos veterinarios utilizados en acuicultura. Se revisa el estado actual de la evaluación de riesgo ambiental en Chile y se identifican aspectos críticos y factibles de corregir en el marco de los procedimientos utilizados.

Full Text Available There is a clear need to measure the correct implementation of the European Framework through the employability of the alumni. The evaluation of the deployment of the Qualifications Frameworks in the European Higher Education Area (QF-EHEA/QF should shed significant light on the action that must be taken by legislators and higher education managers to foster employability and guarantee the sustainability of the EHEA. We propose a methodology based on a Survey on Access to the Labour Market (SALM to assess the correlation between the education provided to the students and the practical utility of the knowledge acquired in the workplace. A questionnaire has been produced to measure the competencies and descriptors that had been theoretically defined within the QF-EHEA. Fifteen questions were disguised so that the six QF-EHEA descriptors were quantified through the difference between education and utility. The quantification methodology for the framework has been tested successfully on the former students of a higher education center in Spain. In this center, the alumni perceived that the utility of their acquired competencies and their employability level was greater than their education content, while both levels were reasonably high. The results hold for both Bachelor’s and Master’s degrees.

The aim of this study was evaluate the effect of photodynamic inactivation mediated by eosin Y in Salmonella enterica serotype Typhimurium ATCC 14028, Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, Staphylococcus aureus ATCC 25923 and Bacillus cereus ATCC 11778. Bacteria (10 7 CFU per ml) were incubated with eosin Y at concentrations ranging from 0·1 to 10 μmol l -1 , irradiated by green LED (λ max 490-570 nm) for 5, 10 and 15 min and the cellular viability was determined. Pseudomonas aeruginosa was completely inactivated when treated with 10 μmol l -1 eosin Y for 10 min. Treatments reduced B. cereus and Salm. Typhimurium counts to 2·7 log CFU per ml and 1·7 log CFU per ml, respectively. Escherichia coli counts were slightly reduced. Staphylococcus aureus presented the highest sensitivity, being completely inactivated by eosin Y at 5 μmol l -1 and 5 min of illumination. The reduction of cellular viability of photoinactivated Staph. aureus was also demonstrated by flow cytometry and morphological changes were observed by scanning electron microscopy. Eosin Y in combination with LED produced bacterial inactivation, being a potential candidate for photodynamic inactivation. This study evidenced the efficacy of photodynamic inactivation as a novel and promising alternative to bacterial control. © 2018 The Society for Applied Microbiology.

Full Text Available Purpose: The aim of this study was to investigate antimicrobial and biofilm removal potential of Zataria multiflora essential oil (ZEO and silver nanoparticle (SNP alone and in combination on Staphylococcus aureus and Salmonella Typhimurium and evaluate the mechanism of action. Methods: The minimum inhibitory concentration (MIC, and optimal inhibitory combination (OIC of ZEO and SNP were determined according to fractional inhibitory concentration (FIC method. Biofilm removal potential and leakage pattern of 260-nm absorbing material from the bacterial cell during exposure to the compounds were also investigated. Results: MICs of SNP for both bacteria were the same as 25 μg/ mL. The MICs and MBCs values of ZEO were 2500 and 1250 μg/mL, respectively. The most effective OIC value for SNP and ZEO against Salm. Typhimurium and Staph. aureus were 12.5, 625 and 0.78, 1250 μg/ mL, respectively. ZEO and SNP at MIC and OIC concentrations represented a strong removal ability (>70% on biofilm. Moreover, ZEO at MIC and OIC concentrations did a 6-log reduction of primary inoculated bacteria during 15 min contact time. The effect of ZEO on the loss of 260-nm material from the cell was faster than SNP during 15 and 60 min. Conclusion: Combination of ZEO and SNP had significant sanitizing activity on examined bacteria which may be suitable for disinfecting the surfaces.

Schinus terebinthifolius leaves are used for treating human diseases caused by micro-organisms. This work reports the isolation, characterization and antimicrobial activity of S. terebinthifolius leaf lectin (SteLL). The isolation procedure involved protein extraction with 0.15 mol l(-1) NaCl, filtration through activated charcoal and chromatography of the filtrate on a chitin column. SteLL is a 14-kDa glycopeptide with haemagglutinating activity that is inhibited by N-acetyl-glucosamine, not affected by ions (Ca(2+) and Mg(2+)) and stable upon heating (30-100 °C) as well as over the pH 5.0-8.0. The antimicrobial effect of SteLL was evaluated by determining the minimal inhibitory (MIC), bactericide (MBC) and fungicide (MFC) concentrations. Lectin was active against Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, Salmonella enteritidis and Staphylococcus aureus. Highest bacteriostatic and bactericide effects were detected for Salm. enteritidis (MIC: 0.45 μg ml(-1)) and Staph. aureus (MBC: 7.18 μg ml(-1)), respectively. SteLL impaired the growth (MIC: 6.5 μg ml(-1)) and survival (MFC: 26 μg ml(-1)) of Candida albicans. SteLL, a chitin-binding lectin, purified in milligram quantities, showed antimicrobial activity against medically important bacteria and fungi. SteLL can be considered as a new biomaterial for potential antimicrobial applications. © 2012 The Society for Applied Microbiology.

Influenza and Other Respiratory Viruses 5(1), 1–5. Background  Globally, respiratory infections are the primary cause of illness in developing countries, specifically among children; however, an etiological agent for many of these illnesses is rarely identified. Objectives  Our study aimed to estimate the frequency of human bocavirus (HBoV) infection among pediatric populations in Argentina, Nicaragua and Peru. Methods  We conducted a cross‐sectional study using stored samples of an influenza‐like illness surveillance program. Irrespective of previous diagnosis, nasopharyngeal or nasal swab specimens were randomly selected and tested using real‐time PCR from three sites during 2007 from patients younger than 6 years old. Results  A total of 568 specimens from Argentina (185), Nicaragua (192) and Peru (191) were tested. The prevalence of HBoV was 10·8% (95% CI: 6·3; 15·3) in Argentina, 33·3% in Nicaragua (95% CI: 26·6; 40·1) and 25·1% in Peru (95% CI: 18·9; 31·3). Conclusions  These findings demonstrate circulation of HBoV in Argentina, Nicaragua and Peru among children with influenza‐like symptoms enrolled in a sentinel surveillance program. PMID:21138534

The purpose of this study was to investigate the efficacy of continuous ohmic heating for reducing Escherichia coli O157:H7, Salmonella Typhimurium and Listeria monocytogenes in orange juice and tomato juice. Orange juice and tomato juice were treated with electric field strengths in the range of 25-40 V cm(-1) for different treatment times. The temperature of the samples increased with increasing treatment time and electric field strength. The rate of temperature change for tomato juice was higher than for orange juice at all voltage gradients applied. Higher electric field strength or longer treatment time resulted in a greater reduction of pathogens. Escherichia coli O157:H7 was reduced by more than 5 log after 60-, 90- and 180-s treatments in orange juice with 40, 35 and 30 V cm(-1) electric field strength, respectively. In tomato juice, treatment with 25 V cm(-1) for 30 s was sufficient to achieve a 5-log reduction in E. coli O157:H7. Similar results were observed in Salm. Typhimurium and L. monocytogenes. The concentration of vitamin C in continuous ohmic heated juice was significantly higher than in conventionally heated juice (P pasteurize fruit and vegetable juices in a short operating time and that the effect of inactivation depends on applied electric field strengths, treatment time and electric conductivity. © 2012 The Authors.

This study aimed to record the use, and knowledge that residents from São Francisco community (Paraiba, Brazil) have regarding the Cactaceae. Semi-structured interviews were carried out with 118 informants; 50 men and 68 women. The cacti cited in this study were organised into use categories and use values were calculated. Differences in the values applied to species and use categories by men and women were compared via a G test (Williams). The nine species identified were: Cereus jamacaru DC., Melocactus bahiensis (Brtitton & Rose) Luetzelb., Nopalea cochenillifera (L.) Salm-Dyck., Opuntia ficus indica (L.) Mill, Opuntia stricta (Haw.)

Taylor & Stuppy. In total, 1,129 use citations were recorded, divided into 11 categories. The use value categories with the highest scores were forage (0.42), food (0.30) and construction (building) (0.25). P. pachycladus showed the greatest use value, versatility and number of plant parts used. The survey showed that the Cactaceae is extremely important for several uses and categories attributed to different species. Apart from contributing to the ethnobotanical knowledge of the Cactaceae, another important focus of this study was to reinforce the necessity for further studies that record the traditional knowledge about this plant family, which has been lost in younger generations.

The offshore oil and gas exploration that is currently taking place on Sakhalin Island was discussed, with particular reference to the status of Sakhalin Energy and the challenges facing oil and exportation from the ice covered waters of Russia's Sea of Okhotsk. Sakhalin Energy, an incorporated joint venture of a consortium of companies, completed a feasibility study for oil production off the east coast of Sakhalin Island in December 1992. Sakhalin Energy has two fields, namely the Piltun Astokhskoye and Lunskoye fields. The Piltun Astokhskoye field is currently under production via the Molikpaq platform and the Lunskoye field and northern part of Piltun Astokhskoye field are currently being developed under the Phase 2 project. Since 1999, Sakhalin Energy has been producing oil from a caisson structure drilling rig which was fitted with ice protection shielding around the waterline in order to comply with Russian requirements. Production is via an undersea pipeline to a Single Anchor Leg Mooring (SALM) unit and then to a Floating Storage and Offloading unit (FSO). A brief outline of the structure was presented along with current ice management procedures and arrangements. In order to maximize the length of the production season, ice management is used to enable an early start and a late end to production. It was noted that great care is taken to ensure that the operations in ice are carried out with consideration of the environmentally sensitive area that is home to the endangered Western Gray Whale and Stellar Sea Eagle. 3 refs., 1 tab., 7 figs.

This study examined the effect of feeding heat-killed Lactobacillus cells on the survival of Caenorhabditis elegans nematodes after Salmonella Typhimurium and Yersinia enterocolitica infection. The feeding of heat-killed Lactobacillus plantarum 133 (LP133) and Lactobacillus fermentum 21 (LP21) cells to nematodes was shown to significantly increase the survival rate as well as stimulate the expression of pmk-1 gene that key factor for C. elegans immunity upon infection compared with control nematodes that were only fed Escherichia coli OP50 (OP50) cells. These results suggest that heat-killed LP133 and LF21 cells exert preventive or protective effects against the Gram-negative bacteria Salm. Typhimurium and Y. enterocolitica. To better understand the mechanisms underlying the LF21-mediated and LP133-mediated protection against bacterial infection in nematodes, transcriptional profiling was performed for each experimental group. These experiments showed that genes related to energy generation and ageing, regulators of insulin/IGF-1-like signalling, DAF genes, oxidation and reduction processes, the defence response and/or the innate immune response, and neurological processes were upregulated in nematodes that had been fed heat-killed Lactobacillus cells compared with nematodes that had been fed E. coli cells. In this study, the feeding of heat-killed Lactobacillus bacteria to Caenorhabditis elegans nematodes was shown to decrease infection by Gram-negative bacteria and increase the host lifespan. C. elegans has a small, well-organized genome and is an excellent in vivo model organism; thus, these results will potentially shed light on important Lactobacillus-host interactions. © 2015 The Society for Applied Microbiology.

The pages are numbered consecutively over the two volumes, with page numbers greater than 702 contained in the second volume. There are three index sections. Main index. Arranged by national sector (UK, Norway etc.) Within each sector the entries are alphabetical by operator name. This index contains page numbers for the book entries: the other two index sections should be used with the main index to find the exact location of an entry; Index by field. If the reader knows a field name (e.g. Kittiwake) but not the operator or the national sector, this index will reference them; Index by installation. Each installation (''Fulmar SALM'', ''Togi'') is named, giving the operator, field and national sector where it is located. This index is also useful for locating particular kinds of installations, such as subsea completions; The book is intended to provide a factual overview of field development activity in the North Sea (a term loosely used to include the Irish Sea and the Baltic Sea). The aim is therefore to provide some background, specifications and history on every offshore installation in that area. Speculative or evaluative commentary is avoided where possible. No attempt has been made to forecast the form or probability of future developments, except in those few instances where announcements have been made by the oil company itself, and these are, clearly indicated.

Seventy one compounds were identified in the investigated Aloe species, of which cis-p-coumaric acid derivaties, 3,4-O-(E caffeoylferuloylquinic acid and caffeoyl quinic acid hexoside were the most common phenolic acids identified. Aloeresin E and isoaloeresin D, 2'-O-feruloylaloesin were the common anthraquinones identified. Lucenin II, vicenin II, and orientin were the common identified flavonoids in the investigated Aloe species. 6'-Malonylnataloin, aloe-emodin-8-O-glucoside, flavone-6,8-di-C-glucosides could be considered as chemotaxonomic markers for the investigated Aloe species. The eight Aloe species had significant anti-inflammatory activity, in addition to the significant acceleration of diabetic wound healing in rats following topical application of the methanol extracts of their leaves. This is the first simultaneous characterization and qualitative determination of multiple phenolic compounds in Aloe species from locally grown cultivars in Egypt using HPLC–DAD–MS/MS, which can be applied to standardize the quality of different Aloe species and the future design of nutraceuticals and cosmetic preparations.

Full Text Available The objective of this trial was to evaluate the effect of the partial replacement of corn by forage cactus (Nopalea cochenillifera Salm Dyck in the diets of lactating goats on the nutrient intake, milk production and composition and ingestive behavior. Five crossbreed Saanen x Pardo Alpina goats with body weights of 47 ± 3.3 kg were used in the study. The design was 5x5 Latin square design, in which the treatments were as follows: 20, 25, 30, 35 and 40% of girl cactus included in the diet as a partial replacement of corn, with 0, 18, 36, 54 and 72% of the added the cactus comprising of gliricidia (Gliricidia sepium (Jacq Walp as roughage in all treatments. Treatment did not affect (P > 0.05 the dry matter intake, crude protein, neutral detergent fiber, acid detergent fiber and total digestible nutrients with the increasing levels of cactus in the diet, presenting means of 1.64, 0.26, 0.82, 0.54 and 1.17 kg day-1, respectively. In the same way, no influence was observed on the daily milk production and levels of fat, protein, lactose and total solids of milk, which averaged 1.18 kg day-1; 3.74, 3.34, 5.06 and 13.56%, respectively. The inclusion of cactus also had no influence (P > 0.05 on the ingestion behavior. The treatment with 35% cactus showed a lower impairment of food intake (31%. The partial replacement of the corn by the girl cactus in the diets of dairy goats can be accomplished because it does not alter the intake, milk yield and composition and feeding behavior. The replacement of up to 54% corn by the cactus is recommended to reduce producer costs for food.

The AquaDEB project (phase I): Analysing the physiological flexibility of aquatic species and connecting physiological diversity to ecological and evolutionary processes by using Dynamic Energy Budgets

The European Research Project AquaDEB (2007-2011, http://www.ifremer.fr/aquadeb/) is joining skills and expertise of some French and Dutch research institutes and universities to analyse the physiological flexibility of aquatic organisms and to link it to ecological and evolutionary processes within a common theoretical framework for quantitative bioenergetics [Kooijman, S.A.L.M., 2000. Dynamic energy and mass budgets in biological systems. Cambridge University Press, Cambridge]. The main scientific objectives in AquaDEB are i) to study and compare the sensitivity of aquatic species (mainly molluscs and fish) to environmental variability of natural or human origin, and ii) to evaluate the related consequences at different biological levels (individual, population, ecosystem) and temporal scales (life cycle, population dynamics, evolution). At mid-term life, the AquaDEB collaboration has already yielded interesting results by quantifying bio-energetic processes of various aquatic species (e.g. molluscs, fish, crustaceans, algae) with a single mathematical framework. It has also allowed to federate scientists with different backgrounds, e.g. mathematics, microbiology, ecology, chemistry, and working in different fields, e.g. aquaculture, fisheries, ecology, agronomy, ecotoxicology, climate change. For the two coming years, the focus of the AquaDEB collaboration will be in priority: (i) to compare energetic and physiological strategies among species through the DEB parameter values and to identify the factors responsible for any differences in bioenergetics and physiology; and to compare dynamic (DEB) versus static (SEB) energy models to study the physiological performance of aquatic species; (ii) to consider different scenarios of environmental disruption (excess of nutrients, diffuse or massive pollution, exploitation by man, climate change) to forecast effects on growth, reproduction and survival of key species; (iii) to scale up the models for a few species from

Motherhood and subsistence work: the Tamang of rural Nepal.

Panter-brick, C

1989-06-01

A time-allocation study conducted over a 1-year period among rural women in Nepal indicated that these women are able to perform rigorous subsistence labor during pregnancy and motherhood through cultural practices that facilitate a combining of economic and childcare duties. The fieldwork was conducted in 1982-83 in the predominately Tamang village of Salme. A total of 7678 hours of minute-by-minute observation were collected on Tamang women and their male kin from 43 households. The sample included 19 nonpregnant, nonlactating women and 24 pregnant or lactating mothers. Among the Tamang, agriculture is the responsibility of women, and nonpregnant and pregnant/lactating women devoted similar numbers of hours a day (5-8 hours, depending on the season) to working fields. In addition, there were no significant differences in the amount of time nonpregnant and pregnant/lactating women devoted to animal husbandry, mountain work, and travel. The Tamang women did not ease their workloads in the final weeks of pregnancy--a finding that is consistent with a practice of not making allowances in economic activity level for age, sex, physical fitness, or maternal status due to severe labor shortage and the tight time schedule inherent to agricultural production. On the other hand, there was evidence of behavioral flexibility to cope with the demands of women's dual roles. Mothers of infants take their babies to the fields with them and breastfeed during their rest periods. The use of mobile cattle shelters minimizes the amount of time that is spent away from children. Older children care for younger siblings--a phenomenon facilitated by the long interbirth intervals among the Tamang--and contractual exchanges take place among families. The health risk of this arrangement seems greatest for older children who are left behind during periods of intense agricultural activity and are often deprived of adequate nutrition.

In the present work the acidophilic actinobacteria strain was used as a novel reducing agent for the cheap, green and single-step synthesis of nanostructure silver particles. Structural, morphological and optical properties of the synthesized nanoparticles have been characterized by spectroscopy, dynamic light scattering and electron microscopy approach. The antimicrobial activity of silver nanoparticles against clinical strains such as Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Proteus mirabilis and Salmonella infantis alone and in combination with antibiotics were studied. The crystalline and stable biosynthesized silver nanoparticles ranged in size from 4 to 45 nm and were mostly spherical in shape being characterized evolving several analytical techniques. The bioAgNPs inhibited growth of most bacterial strains. The highest antimicrobial activity was observed against Ps. aeruginosa (10 mm), followed by Staph. aureus, B. subtilis and Pr. mirabilis (all 8 mm). The lower activity was noticed for E. coli and Kl. pneumoniae (6 and 2 mm, respectively). Moreover, the synergistic effect of bio(AgNPs) with various commercially available antibiotics was also evaluated. The most significant results were observed for bio(AgNPs) combined with tetracycline, kanamycin, ampicillin and neomycin, followed by streptomycin and gentamycin against E. coli, Salm. infantis and Kl. pneumoniae. The most resistant bacteria to commercial antibiotics was Pr. mirabilis. The Streptacidiphilus sp. strain CGG11n isolated from acidic soil can be used to efficiently synthesize the bioactive nanoparticles using inexpensive substances in an eco-friendly and nontoxic manner. The present work provides helpful insight into the development of new antimicrobial agents with the synergistic enhancement of the antibacterial mechanism against pathogenic micro-organisms.

Full Text Available Over the last 20 years, the Norwegian production of salmon and rainbow trout has increased by about 10% per year and will exceed 1 million MT in 2010. All on-growing after stocking in sea takes place in open cages in the fjords and along the coast, and the average cage volume has increased by about 300 times since the 1980's. Out of a total number of 4,000 cages more than 1,200 cages hold 20,000-60,000 m³. In 2005, the term 'maximum allowable biomass (MAB' was introduced and limits the highest annual production to 65 tons per 1,000 m³ licensed volume. Generally, the increasing volume and deeper cages have made the control of the fish stock more challenging. Sea lice attacks, especially in South Norway, have represented a major problem over the last three years. Reduced growth, increased mortality and lice treatment leads to significant losses and extra costs for the industry. Some recent reports indicate that increased use of wrasses in the cages improved the situation in the summer 2010 compared to the previous year. Extensive vaccinating and strict regulations regarding handling, etc. usually result in effective protection against diseases, but still there may occur regional outbreaks of serious diseases, such as pancreas disease (PD and infectious salmon anaemia (ISA. Attacks of sea lice and escape of salmon and trout from fish farms are considered to be among the main reasons for the strongly reduced wild stocks of sea trout and a reduced return of salmon spawners in the fjords and along the coast of southwest Norway.Durante los últimos 20 anos, la producción de salmón y trucha arcoiris en Noruega se ha incrementado en un 10% al ano y sobrepasará 1 millón de toneladas para el 2010.

En general las truchas (Salmo trutta y Oncorhynchus mykiss representaron más de 60 % de la abundancia total de peces y más de 80 % de la biomasa total, además 40 % de los arroyos muestreados no presentaron peces nativos. Los salmones traídos para acuicultura tales como O. kisutch, Salmo salar, y O. tshawytscha solo estuvieron presentes en lagos que tenían salmonicultura, aun cuando no parecen reproducirse exitosamente en los arroyos afluentes. Pusimos a prueba el efecto del origen de los arroyos (cordillera de los Andes, valle central o cordillera de la Costa sobre la abundancia de las especies y encontramos que la trucha arco iris estuvo más restringida a los arroyos preandinos con mayor descarga, mientras la trucha café se distribuyó ampliamente no respondiendo a otras características o atributos específicos de las cuencas que se midieron. La abundancia relativa de peces nativos fue mayor en los lagos que en los arroyos, en tanto la mayor biodiversidad de peces nativos se encontró en arroyos del valle central. Las especies más comunes fueron Galaxias maculatus, G. platei, Brachygalaxias bullocki, Aplochiton zebra y Basilichthys australis. Arroyos con mayor conductividad, más áreas de pozones, más sedimentos finos y con bajas densidades de trucha café fueron más adecuados para peces nativos. Es así que cuencas con mayor disturbio antropogénico parecen ser refugio para los mismos.

Full Text Available Chromosomal characterization of coho salmon samples from three fish farms in southern Chile (Polcura, Castro and Coyhaique was carried out in order to compare their chromosome constitutions. All populations had a 2n = 60; however, Polcura and Coyhaique had a different chromosome arm number (NF = 110; 40m + 10sm + 10st/t than Castro (NF = 108; 40m + 8sm + 12st/t. Variation in NF was due to chromosome pair 25, which was submetacentric in Coyhaique and Polcura, but subtelocentric in Castro. In all karyotypes, a large submetacentric chromosome pair exhibited an interstitial secondary constriction in the short arm. The observed variability in chromosome arm number agrees with previous reports for O. kisutch, and in this particular case it seemed to be caused by a pericentric inversion of pair 25. Cultured populations of Chilean coho salmon are, therefore, likely to be cytogenetically variable.A caracterização cromossômica de amostras de salmon tipo coho de três criações de peixes do sul do Chile (Polcura, Castro e Coyhaique foi feita com a intenção de comparar suas constituições cromossômicas. Todas as populações apresentaram 2n = 60; contudo, Polcura e Coyhaique tiveram um número de braços cromossômicos (NF = 110; 40m + 10sm + 10st/t diferente de Castro (NF = 108; 40m + 8sm + 12st/t. A variação no NF deveu-se ao par cromossômico 25, que era submetacêntrico em Coyhaique e Polcura e subtelocêntrico em Castro. Em todos os cariótipos, um grande par cromossômico submetacêntrico exibiu uma constrição secundária intersticial no braço curto. A variabilidade observada no número de braços cromossômicos concorda com relatos prévios para O. kisutch e, neste caso particular, parece ter sido causada por uma inversão pericêntrica no par 25. Portanto, populações cultivadas de salmão chileno do tipo coho provavelmente são citogeneticamente variáveis.

The Sakhalin Energy Investment Company (SEIC) has been producing oil at the Molikpaq platform off the east coast of Sakhalin Island since 1999. The Molikpaq oil production occurs during the open water summer season. When ice begins to form in late November, an Ice Management Team begins to monitor conditions at the site to ensure a safe operation. This paper described the ice monitoring program designed to provide extensive ice and environmental data to support risk management and allow the planning of safe oil production operations using a Single Anchor Leg Mooring( SALM) system, Floating Storage and Offloading System (FSO), and export tankers in ice. The following 2 key aspects of the in-ice operations were covered: ice management to protect the offshore loading operation on a minute by minute basis in moving ice, and also ice forecasting, to determine when any unmanageable ice might approach the tanker loading site and cause the shut down of operations in the fall and during the startup of operations in the spring. The forecasting of ice drift, ice formation and growth in the fall and ice decay in the spring were discussed. It was noted that in the last few years, the date on which ice first appears is getting later. Operations cease for the winter before the ice is forecast to become a problem for the operations. The Ice Management Team returns to the site in May when the ice melts and and is no longer harmful to the operations. The Ice Management Team consists of 9 individuals with several years of operational ice experience. Their tasks include data collection from satellite images; helicopter ice reconnaissance; ice breaker ice maps; radar ice maps and ice drift; and, ice drift analysis using terra MODIS satellite images. A daily or twice daily weather forecast is provided by a commercial weather forecasting company. These forecasts provide the winds, gusts, cloud cover, air temperature, wind wave and swell for every 6 hours for the first 3 days, then every

El NH3 indicó la mayor dispersión de resultados y los valores de O2 con el kit estuvieron siempre por encima del valor registrado por el oxímetro. Estos resultados sugieren que para algunas variables (amoniaco, nitrito, el kit tiene imprecisiones determinando los valores reales en las aguas analizadas. Para el nitrito, ésto sería de riesgo para especies muy susceptibles al mismo (ej. salmónidos, peces gato mientras que para el amoniaco, imprecisiones en la cuantificación serían de alto riesgo para todas las especies dada la alta susceptibilidad a este metabolito.

Full Text Available 800x600 Este trabalho teve por objetivo realizar o primeiro ciclo de seleção massal na população PM1 de melão, visando desenvolver uma cultivar de melão que combine as características de resistência ao transporte do melão valenciano com as características de qualidade do melão americano para o Estado de Alagoas. A pesquisa foi desenvolvida, em condições de campo, na Área Experimental do Setor de Melhoramento Genético de Plantas do Centro de Ciências Agrárias da Universidade Federal de Alagoas, nos anos de 2010 e 2011. A semeadura da população PM1 de melão foi realizada no dia 18/11/2010, com o desbaste aos 25 dias após a semeadura e a colheita realizada aos 67 dias. Na seleção foram consideradas plantas que apresentaram frutos de coloração da casca amarela, sem costelas, sem rendilhamento, polpa com a coloração salmão e com pedúnculo que não se desprendesse da planta quando o fruto está maduro. Dos 710 frutos colhidos da população em estudo foram selecionados 12 frutos que apresentavam as características desejadas, sendo submetidos às seguintes avaliações: Peso dos Frutos, em g, Diâmetro Longitudinal, em cm, Diâmetro Transversal, em cm, Espessura da Polpa, em cm e Espessura da Casca, em cm. Foi realizada uma distribuição de frequências absolutas e relativas de classes em relação ao peso dos 710 frutos da população PM1 de melão. Para os frutos selecionados foram estimadas as médias aritméticas, os valores da amplitude total, o coeficiente de variação e o intervalo de confiança (95% para cada variável analisada.  Foi formado um grupo após a seleção que apresenta as características desejadas.

Full Text Available El método tradicional de sacrificio de trucha arcoiris (Onconrhynchus mykiss mediante aturdimiento automático seguido de desangre por corte branquias fue comparado con un método alternativo por disminución rápida de la temperatura (-3.5°C con inmersión en hielo líquido sin usar desangrado. Se midió el pH muscular como un indicador de estrés alcanzado durante las fases de confinamiento y de sacrificio, y se evaluó la capacidad de retención de sangre que tienen las vísceras y cabezas como fuentes potenciales para uso y resguardo de la bioseguridad debido a riesgos de dispersión de sangre al medio. Los pesos medios de las vísceras y cabezas por ejemplar con el método alternativo de sacrificio superaron en 24,4 g al método tradicional, lo que equivale a un 1,07% del peso medio del cuerpo de un ejemplar promedio. El método alternativo acumuló un 5,3% más de peso por ejemplar en las vísceras, y un 4,9% más de peso en las cabezas que el método tradicional. La retención estimada de sangre debido a las vísceras y cabezas con el método alternativo correspondió al 44,6% del total de sangre derramada por el método tradicional. Proyectando una producción de salmónidos (truchas y salmones al año 2014 de 900.000 ton, la retención de sangre sería al menos de 9.630 ton. No se evidenciaron diferencias significativas en el pH muscular entre los dos métodos. El pH de los peces en el punto de confinamiento fue igual a 7,06 magnitud que disminuyó aproximadamente a pH = 6,5 en la fase de sacrificio independiente del método de sacrificio utilizado. El método alternativo no produce la muerte instantánea del pez, pero tiene mayor capacidad que el método tradicional de retener sangre en vísceras y cabezas para ser usada en aumentar la bioseguridad, y si se combina con métodos más eficientes para alcanzar una rápida inconsciencia, por ejemplo aturdimiento eléctrico, se tendría un método de sacrificio combinado útil para

Full Text Available The interest in characterizing fish immune responses against pathogens or discovering new immunostimulant molecules requires the use of mass screening techniques. The classical model has been the challenge in 1000 L tanks, using a high number of fishes, resulting in high economic cost. In this work, the purpose was to minimize the costs of such tests using in vitro cellular models. In primary cultures of head kidney leucocytes (HKL immune response to Zymosan A, a type of β-glucan, was evaluated. The quantification and detection of pro-inflammatory cytokines was done based on both enzymatic activity and ELISA. The activity of phagocyte oxidase and inducible nitric oxide synthase (iNOS was measured indirectly through NBT reduction by reactive oxygen species and Griess reaction to nitric oxide, respectively. For detecting pro-inflammatory cytokines such as TNF-α, IL-6 and IL-Ιβ, monospecific antibodies generated in our laboratory were used by indirect ELISA. The immune parameters were evaluated at different concentration of Zymosan A and the evolution of the immune response over time was established. The results suggest the better time for evaluating the immunostimulant capacity of glucans and the appropriate dose of it, which is required to demonstrate the activation of macrophages (ROS and iNOS and the production of pro-inflammatory molecules, both as indicators of good immune response. Currently, work is being conducted improving these methods, creating an ELISA sandwich and generating antibodies against total proteins of HKL for pre-absorption of induced samples. In particular, the implementation of ELISA for the characterization of cytokine secretion profiles is a biotechnological contribution in aquaculture, which has not been implemented before this work.El interés en la caracterización de la respuesta inmune de peces contra patógenos o el descubrimiento de nuevas moléculas inmunoestimulantes, requiere el uso de técnicas de uso masivo y rápido. El modelo clásico ha sido el desafío en estanques de 1000 L, con un elevado número de peces, lo que tiene un alto costo económico. El objetivo de este trabajo fue reducir al mínimo los costos de dichos ensayos, utilizando modelos celulares in vitro. Para ello, se evaluó el efecto del inmunoestimulante de Zymosan A, un tipo de β-glucano, sobre la respuesta inmune en cultivos primarios de leucocitos de rinón cefálico (HKL, mediante la cuantificación enzimática y la detección de citoquinas pro-inflamatorias. La actividad de la fagocito oxidasa y de la óxido nítrico sintetasa inducible (iNOS, se midió indirectamente a través de la reducción de NBT, por especies reactivas de oxígeno, y la reacción de Griess para óxido nítrico, respectivamente. La detección de citoquinas pro-inflamatorias como el TNF-α, IL-6 e IL-Ιβ, se realizó mediante ELISA indirecto, con anticuerpos monoespecíficos generados en nuestro laboratorio. Los parámetros inmunológicos fueron evaluados en diferentes concentraciones y tiempos de incubación con el Zimosán A. Los resultados sugieren las condiciones óptimas para la evaluación de glucanos con capacidad inmunoestimulante, en base a indicadores de buena respuesta inmunitaria, que considera la activación de macrófagos (ROS e iNOS y la secreción de moléculas pro-inflamatorias. Actualmente, el trabajo está dirigido a mejorar estos métodos, a través de la creación de un ELISA sandwich y generación de anticuerpos contra las proteínas totales de HKL para la pre-absorción de las muestras inducidas. En particular, la aplicación de ELISA para la caracterización de los perfiles de secreción de citoquinas es una contribución biotecnológica en la acuicultura, lo que no ha sido aplicado antes de este tipo de análisis.

Full Text Available RESUMEN: Se da cuenta de nuevos hallazgos en la cueva de Ekain, a raíz de la realización de la réplica llevada a cabo de dicha cueva. En dos de los casos, probables vulva y bóvido, se aprovechan accidentes de la roca, tales como bordes rocosos, volúmenes, grietas y hoyuelos, cosa repetida en numerosas figuras de esta cueva. La vulva es un hoyo fusiforme relleno de pintura roja, igual a la del caballo contiguo. El posible bóvido es un reborde rocoso, que puede sugerir el vientre de un animal al que se han señalado con trazos negros el arranque de la pata anterior y zonas de la cabeza y dorso. Por ello comienza el trabajo indicando estos aprovechamientos en figuras ya conocidas anteriormente. En los demás casos se trata de líneas, puntos y manchas negras y rojas. Así un conjunto de ellas están en la galería Auntzei cerca del salmón y de las pequeñas cabras que se encuentran en esta galería, tanto a un lado como al otro de la misma. Son en total 8 manchas rojas, 1 negra, 5 puntos rojos, 1 negro y 5 trazos negros. En la zona de Erdialde, zona central de la cueva, hay más manchas rojas así como líneas y puntos negros, que suman un total de 4 manchas rojas, 2 puntos rojos, 4 puntos negros y 7 trazos o líneas negras.ABSTRACT: We describe the new findings in Ekain cave due to the replica that has been done of this cave. In two cases, “vulva and bovid”, the relief of the wall has been used such as edges of the rock, volumes, cracks or small holes, and this has been repited in many other paintings of this cave. The “vulva” is a fusiform hole with red painting in it, the same red painting as the horse nearby. The posible “bovid” is a ridge in the rock that may suggest the abdomen of an animal where the “legs and arms” have been removed as well as the head and the “torax”. This is the reason why the paper starts describing the use of the cave relief in other known cases in this cave. The rest of the new findings are

Epidemiology of foodborne diseases: a worldwide review.

the world do show some common elements. Salmonella is still the most important agent causing acute foodborne disease, with Salmonella enteritidis and S. typhimurium being of most concern. Foods of animal origin, particularly, meat and eggs, were most often implicated. Desserts, ice cream and confectionery items were products also mentioned, but some of these would have egg as a raw or incompletely cooked ingredient. Incidents most frequently occurred in homes or restaurants, and the main factors contributing to outbreaks were poor temperature control in preparing, cooking and storing food. Clostridium botulinum, Salmonella and VTEC are more frequently documented in industrialized than in developing countries. ETEC, EPEC, Shigella, Vibrio cholerae and parasites are the main scourges in developing countries, but it is uncertain how many cases are attributed to food, to water or to person-to-person transmission. The apparent decrease of S. aureus and C. perfringens outbreaks in industrialized countries may be related to improved temperature control in the kitchen. An increasing number of illnesses are international in scope, with contamination in a commercial product occurring in one country and affecting persons in several other countries, or tourists being infected abroad and possibly transmitting the pathogen to others at home. For Salmonella, a rapid alert and response coordination is being encouraged through Salm-Net and other international programs. However, unless such a network is worldwide, tracking clusters of illnesses is going to fall on the countries where the first cases occur, and some of these have very limited resources for investigation and control. It was heartening to see funds recently being allocated to foodborne disease surveillance and control in several industrialized countries, but the same commitment is required by the World Health Organization for the international community.

Full Text Available Nove acessos de Capsicum chinense do Banco Ativo de Germoplasma de pimentas do Instituto Agronômico (IAC foram caracterizados e avaliados nas condições edafoclimáticas de Campinas (SP. O experimento foi realizado de janeiro a outubro de 2010, em blocos casualizados, com nove tratamentos, cinco repetições e oito plantas por parcela. Foram avaliados altura da planta, hábito de crescimento da planta, antese da primeira flor, produtividade, massa fresca do fruto, comprimento do fruto, largura do fruto, conteúdo de capsaicina do fruto fresco, cor do fruto maduro, formato do fruto e superfície do fruto. Para a caracterização da planta e do fruto consideraram-se as quatro plantas centrais de cada parcela; para a extração da capsaicina, utilizaram-se três amostras de cinco frutos de cada acesso. A quantificação de capsaicina foi feita por meio de cromatografia líquida de ultra pressão. A altura das plantas variou de 1,13 a 0,85 m. Constatou-se hábito de crescimento compacto das plantas para a maioria dos acessos. Os acessos mais precoces para antese da primeira flor foram IAC 1644, IAC 1645 e IAC 1643, respectivamente. O acesso IAC 1646 apresentou alta produtividade e maiores largura e massa fresca do fruto e IAC 1641 apresentou os frutos mais longos. IAC 1552 ('Murupi' destacou-se com o maior conteúdo de capsaicina, superando IAC 1646 ('Scotch Bonnet' e IAC 1644 ('Fidalga', do tipo habanero. Observaram-se as cores amarela, laranja, salmão e vermelha para os frutos. Quanto ao formato do fruto, os acessos classificaram-se em alongados, redondos, triangulares campanulados e bloco. Quanto à superfície, caracterizaram-se os frutos como lisos, semi-rugosos e rugosos. Concluiu-se que, nas condições edafoclimáticas em que a pesquisa foi desenvolvida e considerando os acessos avaliados, existe alta variabilidade em pimenta de cheiro para características agronômicas e conteúdo de capsaicina. IAC 1552 destacou-se com o maior conte

As setas férteis são formadas também no micélio aéreo que recobre as sementes, geralmente após cinco dias de incubação. Os acérvulos com massa conidial raramente são visíveis, exceto em sementes danificadas ou mortas. Como característica de C. gossypii, observou-se que as sementes exibem, de modo geral, uma coloração rosada, em decorrência da abundante esporulação; a ausência ou escassez de micélio aéreo e as setas curtas resultam em um crescimento rente ao tegumento e aspecto compacto. Comparativamente, nas sementes com C. gossypii var. cephalosporioides, as setas são mais longas e menos densas; o micélio aéreo com setas férteis ocorre com mais freqüência, conferindo às sementes tonalidades acinzentadas e aspecto solto. A constatação de setas férteis em lesões foliares de ramulose evidencia que, no campo, essas estruturas podem funcionar como autênticos conidióforos, desempenhando um importante papel epidemiológico, ao possibilitar a disseminação dos esporos pelos ventos, a longas distâncias.The growth habit of Colletotrichum gossypii and C. gossypii var. cephalosporioides on artificially

Full Text Available En Chile, la mayoría de las empresas de cultivo de salmones en la fase parr alimentan a los peces con 24 raciones/día; por otra parte, el alimento en el estómago de los peces, puede permanecer cerca de 4 a 5 h. Este trabajo evalúa en base a procedimientos y protocolos productivos, la disminución en la frecuencia de raciones de alimento y su efecto en la supervivencia, crecimiento, conversión y conducta de alimentación de los peces. Se trabajó en condiciones normales de producción comercial, con aproximadamente 1.200.000 peces de 0,17 g durante cuatro meses. Hubo dos tratamientos, el control con 24 raciones/día y el ensayo, que al inicio de la experiencia se entrego 12 raciones/día y al finalizar la experiencia se proporcionó 4 raciones/día. Se emplearon cinco estanques de 18 m³ para cada tratamiento. La disminución en la frecuencia de alimentación, no afectó la supervivencia de Salmo salar, se obtuvo mayor crecimiento en los peces del ensayo, con mejor conversión de alimento, se logró reducción de alimento depositado en el fondo de los estanques y se visualizó mejor apetito en los peces.In Chile, most salmon-farming companies feed fish in the parr phase 24 rations/day. However, food can remain in fish stomachs for around four or five hours. Using productive procedures and protocols, this study evaluates less frequent food rations and how they affect the survival, growth, conversion, and feeding behavior of the fish. The study was conducted over four months under normal commercial production conditions, using approximately 1,200,000 fish of 0.17 g each. There were two treatments: the control, which received 24 rations/day, and the assay, which received 12 rations/day at the onset of the study and 4 rations/day at the end of this. Five tanks, each 18 m³, were used for each treatment. The lower feeding frequency did not affect the survival of Salmo salar. The fish in the assay obtained greater growth and had better food conversion rates. Less food was deposited on the bottom of the assay tanks, and the fish were observed to have better appetites.

. 4. Current data infrastructure and systems supporting GHG quantification in the agricultural sector To understand the challenges facing GHG quantification it is helpful to understand the existing supporting infrastructure and systems for quantification. The existing and developing structures for national and local data acquisition and management are the foundation for the empirical and process-based models used by most countries and projects currently quantifying agricultural greenhouse gases. Direct measurement can be used to complement and supplement such models, but this is not yet sufficient by itself given costs, complexities, and uncertainties. One of the primary purposes of data acquisition and quantification is for national-level inventories and planning. For such efforts countries are conducting national-level collection of activity data (who is doing which agricultural practices where) and some are also developing national or regional-level emissions factors. Infrastructure that supports these efforts includes intergovernmental panels, global alliances, and data-sharing networks. Multilateral data sharing for applications, such as the FAO Statistical Database (FAOSTAT) (FAO 2012), the IPCC Emission Factor Database (IPCC 2012), and UNFCCC national inventories (UNFCCC 2012), are building greater consistency and standardization by using global standards such as the IPCC's Good Practice Guidance for Land Use, Land-Use Change and Forestry (e.g., IPCC 1996, 2003, 2006). There is also work on common quantification methods and accounting, for example agreed on global warming potentials for different contributing gases and GHG quantification methodologies for projects (e.g., the Verified Carbon Standard Sustainable Agricultural Land Management [SALM] protocol, VCS 2011). Other examples include the Global Research Alliance on Agricultural Greenhouse Gases (2012) and GRACEnet (Greenhouse gas Reduction through Agricultural Carbon Enhancement network) (USDA
