Authors: Aguirre Medina Juan Francisco , Yeekón-Méndez Lázaro , Espinosa-Zaragoza Saúl 
Published: February 2019

A greenhouse experiment was conducted to identify the influence of endomycorrhizal fungi on the growth of Tabebuia donnell-smithiiRose. We used collections of endomycorrhizal fungi from Tenampulco, Puebla and San Rafael, Veracruz and the reference fungus Rhizophagus intraradices, which were evaluated with eutric fluvisol soil in combination with sand (1:1 v/v), peat moss (0.80:0.20 v/v) and bovine manure (0.80:0.20 v/v); 5-kg plastic bags were filled with the substrates. Nine treatments were evaluated with the combination of substrates and fungi, under a completely randomized design with four replicates. Morphological, physiological, root colonization and phosphorus content variables were determined in plant tissue 112 days after sowing (das). Results indicate a 121% increase in total biomass in the substrate with soil plus bovine manure added. Among microorganisms, R. intraradicesincreased biomass by 10.8 and 6.0% in relation to the snail and San Rafael collections, respectively. Biofertilization with R. intraradicespromoted stem and leaf area growth, and with the snail isolates, height and leaf area. The highest phosphorus content compared to plants with native endomycorrhizal isolates occurred with R. intraradices.

Published: February 2019

En la Península de Yucatán se desarrollan dos especies Haematoxylum: H. campechianum y H. calakmulense. Se evaluó el estado actual de las poblaciones de ambas especies en diferentes áreas en Campeche, México. Para conocer la distribución histórica y actual se utilizaron registros de herbarios publicados, información de proyectos y expediciones de campo. Para medir la densidad y la estructura poblacional se seleccionaron ocho áreas con concentraciones de individuos de una u otra especie y se establecieron 20 parcelas de 10 x 10 m en cada sitio. En cada parcela se contabilizaron y midieron los individuos de ambas especies con un diámetro del tronco a la altura del pecho (DAP) ≥ 1 cm. Para cada individuo se tomó la altura, el DAP y el número de ramas. Se compararon las variables densidad, altura, DAP y número de ramas entre sitios y las frecuencias absolutas de los intervalos de tamaño y de DAP dentro de cada sitio. Haematoxylum campechianum se encuentra ampliamente distribuido en el estado de Campeche y se localizó formando tintales y como árboles aislados. Haematoxylum calakmulense solo se registró en áreas interiores del estado y presentó valores de densidad más bajos que H. campechianum y en ninguno de los sitios se encontró formando tintales. Para H. calakmulense los individuos más altos alcanzaron 12 m y para H. campechianum 15 m. Considerando que ambas especies tienen gran potencial económico pueden verse afectadas por actividades antropogénicas que provocarían la disminución de sus poblaciones a mediano-largo plazo.

Published: February 2019

En los últimos años, se ha impulsado la busqueda alternativas para reducir el empleo de los fertilizantes inorgánicos, debido al impacto de los agroquímicos sobre el ambiente. Dentro de estas alternativas se ha establecido que los abonos orgánicos, entre los cuales se encuentra el vermicompost (VC), pueden utilizarse para satisfacer la demanda nutritiva de las especies vegetales, sin afectar el rendimiento y la calidad de éstas. El objetivo del trabajo fue evaluar el comportamiento de la calabacita (Cucurbita pepo L.), híbrido Mona Lisa F1, durante la temporada Primavera-Verano 2014, con seis fuentes de fertilización (tratamientos): a) cuatro soluciones nutritivas (T1-T4); b) mezcla vermicompost:arena (2:3, v:v) (T5); y c) mezcla vermicompost:arena (2:3, v:v) + solución nutritiva de Steiner (T6), bajo condiciones de invernadero. Los tratamientos con siete repeticiones se distribuyeron en un diseño completamente al azar. Las variables evaluadas fueron: Longitud del fruto; Diámetro del fruto; Contenido de sólidos solubles; Número de frutos; Peso del fruto; Rendimiento por planta. Para determinar el efecto de los tratamientos sobre las variables evaluadas se aplicaron ANDEVAs y para la comparación de medias se utilizó la prueba de Tukey0.05. La respuesta más favorable para el desarrollo de la calabacita se registró en el tratamiento T6, en el cual se incluyó la combinación del vermicompost:arena con la solución nutritiva de Steiner. Los resultados obtenidos sugieren que la mezcla de VC con solución nutritiva Steiner posee características que permiten ser contemplada como una alternativa para la nutrición de la calabacita.

Published: February 2019

The aim of this study was to evaluated the effect of soaked Mucuna pruriens (MP) seeds in tap water, acid or alkaline solution + cooking on its L-Dopa content and on the productive performance of broiler chickens. Ninety-six sexed chicks aged 21-days old with an initial live weight of 720 ± 80 g were used. Four diets were used, a control without MP (C) and three diets including 25 % MP: a) soaked MP in tap water + cooking (WMP); b) soaked MP in acetic acid solution + cooking (AAMP); c) soaked MP in calcium hydroxide solution + cooking (CHMP). The alkaline treatment reduced 71 % of L-Dopa in comparison to acid or water treatment (53 % and 41 % respectively). In the starter phase, the acid group had the lowest live weight gain (p<0.05) and highest feed conversion ratio when compared to control (p<0.05). Productive performance of birds fed with CHMP and C group was similar (p>0.05). In the finisher phase, there was not statistical difference in feed intake, live weight gain and feed conversion ratio among treatments (p>0.05). No differences were observed in carcass yield (p>0.05), but, the birds fed MP or AAMP had a heavier liver than birds on C group (p<0.05). Results shown that 25 % of CHMP can be used as feedstuff for broiler chickens without negative effects in their productive performance. Keywords: Velvet bean, L-Dopa, Poultry, weight gain.

Published: February 2019

La pudrición de raíz y tallo de plantas del melón, es un factor limitante en la producción del cultivo. El uso indiscriminado de fungicidas, ha causado problemas de resistencia y contaminación ambiental en las áreas agrícolas de México. Una alternativa es el uso de agentes microbianos como Trichoderma, Bacillus y Streptomyces, los cuales favorecen el manejo y control de la enfermedad, inducen el crecimiento y aumentó de la cosecha. Este trabajo se realize, con el objeto de aislar e identificar al agente causal de la pudrición radical del melón en la región de Paila, Municipio de Parras de la Fuente, Coahuila y su control con agentes microbianos. Se recuperaron seis aislamientos, de la misma cantidad de áreas de cultivo, identificados morfológicamente como especies distintas del Género Fusarium. Molecularmente y con base en las secuencias de nucleotidos de las regiones ITS1 e ITS4, se encontró porcentajes de identidad del 97-100 % correspondientes a Fusarium oxysporum y Fusarium solani. Bioensayos de antagonismo in vitro, mostraron que Trichoderma asperellum inhibió hasta un 74%, Bacillus subtillis 46 % y Streptomyces mutabilis 35 %, para las cepas de Fusarium. Los agentes microbianos representan un recurso para el biocontrol de la pudrición radical y del tallo del cultivo de melón.

Published: February 2019

Abstract. – Prunus serotina is a specie that grows wild or under cultivated conditions in several regions of America, and which has attracted considerable attention as a potential source of antioxidants. The study aimed to evaluate the concentration changes in compounds that contribute to the antioxidant capacity in capulín (Prunus serotina) fruits during the ripening process in order to define the time when the maximum concentration is reached. Antioxidant capacity was evaluated by spectroscopic methods. A completely randomized simple factor design was used for the statistical analysis. It was found that the content of total phenols and flavonoids decreased significantly at S3 (93 DAA) stage of ripening. Total anthocyanins increased significantly to 1.4 . The antioxidant capacity of the fruits had a maximum value of 63.7 at S3 stage of ripening (93 DAA). The results indicated that antioxidant capacity of the fruits is higher before reaching the characteristic purplish coloration, which is an indicator for consumption.

L’étude visait à déterminer l’effet du stress hydrique sur les métabolites sanguins des caprins de race Arbia en Algérie. Quatre groupes de dix boucs chacun ont été aléatoirement soumis à des régimes d’abreuvement différents : le groupe 1 (témoin) avait libre accès à une eau de source (trois litres), tandis que les groupes 2 et 3 recevaient la même eau enrichie respectivement de deux et cinq grammes de chlorure de sodium par litre. Le groupe 4 avait uniquement accès à 25 % de la quantité d’eau distribuée aux boucs du groupe témoin. A la fin de la période expérimentale, des prélèvements sanguins ont été réalisés afin de doser les protéines totales, la créatinine, l’albumine, l’urée, le cholestérol total et le glucose. Les différents traitements ont augmenté les concentrations plasmiques de l’albumine, de la créatinine, des protéines totales et du cholestérol total, ainsi que l’urée des animaux ayant subi une restriction hydrique. Cependant, ils n’ont pas affecté la glycémie. Ces résultats ont montré que l’exposition à court terme (12 jours) de boucs Arbia à la salinisation de l’eau d’abreuvement ou à une restriction hydrique affectait la majorité de leurs métabolites sanguins à l’exception du glucose.

Published: February 2019

Une étude parasitologique a été menée en 2015 sur des chiens de sexe, âge et race différents, vivant en liberté dans la ville de Lubumbashi, République démocratique du Congo. Des échantillons de fèces ont été prélevés et analysés par coproscopie selon une méthode de flottation. Sur les 120 chiens examinés, 78 (65 %) étaient infestés, parmi lesquels 74 (61,7 %) avaient des helminthes gastro-intestinaux et 4 (3,3 %) avaient des coccidies. Les coproscopies ont révélé la présence de cinq espèces de parasites : Ankylostoma spp. (41 chiens), Toxocara canis (22), Toxascaris leonina (8), Isospora canis (4) et Dipylidium caninum (3). I. canis n’a été retrouvé que chez les chiots. Le dépistage fréquent d’ankylostomes et de T. canis suggère qu’il existe à Lubumbashi un risque de contamination de l’homme par ces parasites zoonotiques.

Published: February 2019

Abstract
The use of two pressure transducers in close proximity can enable the separation of the directional travelling pressure waves in pipelines. However, the implementation of this measurement strategy in real water pipes is difficult due to the lack of closely located access points. This paper reports the use of a customised in-pipe fibre optic pressure sensor array for hydraulic transient wave separation and pipeline condition assessment. The fibre optic pressure sensor array can be inserted into a pressurised pipeline through a single access point. The array consists of multiple fibre Bragg grating (FBG)-based pressure sensors in close proximity (∼0.5 m apart). A previously developed wave separation algorithm is adapted to analyse the transient pressure measurement from the FBG sensors. The resultant directional pressure waves are then used to detect pipe sections with a thinner wall thickness. A challenge is the influence of the in-pipe fibre optic sensing cable on the transient pressure measurement. The impact is analysed and adjustments to the pipeline condition assessment algorithm are undertaken to resolve the issue. The successful experimental application verifies the usefulness of the in-pipe fibre optic sensor array, which can facilitate transient-based pipeline condition assessment for buried water pipes with limited access points.
Multi-objective multi-pollutant waste load allocation model for rivers using coupled archived simulated annealing algorithm with QUAL2Kw

Published: February 2019

Abstract
A simulation-optimization approach is a suitable tool in waste load allocation problems when considering competing objectives and complex pollutant fate and transport processes in water bodies. Here, an archived multi-objective simulated annealing (AMOSA) algorithm is developed to determine various decision variables related to multi-pollutant waste load allocation (MPWLA) problems. The developed AMOSA algorithm has been coupled to QUAL2Kw in order to derive optimal MPWLA programs in Gheshlagh River, Kordestan, Iran. Minimizing wastewater treatment plant (WWTP) costs, improving the EquityMeasure, and enhancing water quality index (WQI) of the river have been considered as objective functions of MPWLA problems. The applied WQI integrates various water quality parameters (biochemical oxygen demand (BOD), dissolved oxygen (DO), NH4-N, NO3-N, PO4-P, total suspended solids (TSS), and Coliform) in monitoring stations along the river. Results show in the scenario with the best EquityMeasure, higher pollutant removal rates have been allocated to Sanandaj WWTP effluent and pollutant point source No. 7 (creek of landfill leachate) due to their greater contributions to Gheshlagh River contamination. Owing to high pollutant load effluents and unsuitable background conditions in Gheshlagh River, more specific studies show that the water quality index may not be improved over 0.22, no matter how much cost is incurred or equity is sacrificed.
Improve Healthcare Quality Through Mortality Committee: Retrospective Analysis of Bambino Gesù Children Hospital’s Ten Years’ Experience 2008-2017
Authors: Offidani Caterina , Lodise Maria , Gatto Vittorio , Frati Paola , D'Errico Stefano , Atti Marta L.C.D. , Raponi Massimiliano 
Published: February 2019

Background:
Healthcare quality improvements are one of the most important goals to reach
a better and safer healthcare system. Reviewing in-hospital mortality data is useful to identify areas for
improvement, and to monitor the impact of actions taken to avoid preventable cases, such as those related
to healthcare associated infections (HAI).

Methods:
In this paper, we present the experience of the Mortality Committee of Bambino Gesù Children
Hospital (OPBG). OPBG has instituted a process of systematic revision of all in-hospital deaths
conducted by a multidisciplinary team. The goal is to identify system-wide issues that could be improved
to reduce in-hospital preventable deaths. In this way, the mortality review goes alongside all
the other risk management activities for the continuous quality improvement and patient safety.

Results:
In years 2008-2017, we performed a systematic analysis of 1148 inpatient deaths. In this time
period, the overall mortality rate was 0.4%. Forty-seven deaths were caused due to infections, 10 of
which involved patients with HAI transferred to OPBG from other facilities or patients with community-
acquired infections. Six deaths related to HAI were followed by claims compensations. All these
cases were not followed by compensation because the onset of HAI was considered an inevitable consequence
of the underlying disease.

Conclusion:
Introduction of the mortality review committee has proved to be a valid instrument to improve
the quality of the care provided in a hospital, allowing early identification of care gaps that could
lead to an increase in mortality rates.

Article Highlights Box:
Reduction of preventable deaths is one of the most important goals to be
achieved for any health-care system and to improve the quality of care.
• Several studies have shown that analysis of morbidity and mortality rate helps to detect any factors
that can lead to an increase in in-hospital mortality rates.
• The review of in-hospital deaths allows to learn how to improve the quality and safety of care
through identification of critical issues that lead to an increase in mortality ratio.
• In some medical areas, such as intensive care units or surgery, the implementation of the conference
on mortality and morbidity is more useful for assessing procedures at high risk of errors.
• The implementation of existing databases with data deriving from the systematic review of medical
records and in-hospital deaths appears to be desirable.
• Mortality Review Committees can represent a very useful tool for all the health facilities for the reduction
of preventable deaths, such as those related to HAI.

Authors: Ma Ling , Zhang Xia , Wang Zhiqiong , Huang Lifang , Meng Fankai , Hu Lihua , Chen Yan , Wei Jia 
Published: February 2019

Background:Enhancer of zeste homolog-2 (EZH2), a histone methyltransferase that regulates histone H3 methylation of lysine27 (H3K27me3), is involved in the pathogenesis of myelodysplastic syndrome (MDS). Targeting epigenetic regulators has been identified as a potential treatment target in MDS chemotherapy. Curcumin, a natural compound extracted from turmeric, was found to possess a wide range of anticancer activities in various tumors.Methods:This study was designed to investigate the inhibitory effect and action mechanism of curcumin in myelodysplastic syndrome (MDS) in vitro and in vivo.Results:Our results showed that curcumin can significantly suppress cell proliferation and induce cell apoptosis and cell cycle arrest in human MDS-derived cell lines. It reduced EZH2, DNA methyltransferase 3A (DNMT3a), ASXL1 and downstream H3K4me3, H3K27me3 and HOXA9 expression and inhibited EZH2 and H3K27me3 nuclear translocation. Curcumin also showed anti-cancer effects in a xenograft mouse model and reduced EZH2, H3K4me3 and H3K27me3 in vivo. EZH2 knockdown can reduce the H3K27me3 levels and induce curcumin resistance in vitro but attenuates leukemic transformation in vivo.Conclusion:These findings provide the potential molecular mechanism of curcumin as a therapeutic agent for MDS.

Authors: Hilgeroth Andreas , Yasrebi Kaveh , Suzen Sibel , Hertlein Tobias , Ohlsen Knut , Lalk Michael 
Published: February 2019

Background:
Due to emerging resistances against antibiotics there is a strong need to
find novel antibacterial agents with a novel structure to prevent early resistance developments.

Objective:
Bisindole compounds with antibacterial activities which formally result from the reaction
of an aldehyde with indole motivated to investigate the reaction of a dialdehyde and indole to
give novel structures with potential antibacterial activities.

Methods:
Compounds were yielded by chemical synthesis and purified using column chromatography.
The antibacterial activity was determined as minimal inhibitory growth activity in cultures
of Gram-positive strains of Staphylococcus aureus and Enterococcus species.

Results:
Cyclohepta[2,3-b]indoles have been yielded in a one-step reaction procedure with indole
substitutions at the cycloheptane central core matching a solution for achieving fused novel cycloalkane
indoles with functionalized residues of promising biological activity. So far fused cycloalkane
indoles have not been available in a one-step procedure and moreover, core functionalizations
have been additional challenges. Various indole substitutions have been done to provide a
first set of compounds.

Conclusion:
Substituent-dependent effects have been suggested to influence the antibacterial activity
and first compounds were identified with specific Staphylococcus activities and Enterococcus
species effects towards Enterococcus faecalis as critical pathogens in the hospital with upcoming
resistances against standard antibiotics.
