Environmental Approaches during Planning and Construction Stages of Hydropower Projects in Mexico  [PDF]
María Antonieta Gómez-Balandra, María del Pilar Salda?a-Fabela, Rosa Dina Llerandi-Juárez
Journal of Environmental Protection (JEP) , 2015, DOI: 10.4236/jep.2015.610106
Abstract: During the Environmental Impact Assessment procedure (EIA) for hydropower projects, apart from the compliance with environmental standards and regulations, important environmental and ecosystem changes are foreseen from planning and construction stages. In Mexico, the EIA and environmental standards are being systematically applied and fulfilled at planning and construction stages for hydropower projects. These are mainly related to control air emissions, solid and hazardous wastes, water discharges and deal with protected species. In addition, due to land use changes, forestry compensation procedures have already been established. To comply with project approval conditions, an Environmental Management Plan (EMP) is carried out during construction; it includes mitigation measures, standards, regulations and approval conditions resulting of project review and in some cases requests from the public audience. Monitoring is carried out in the area of influence that is in the works and where it is expected that natural processes are modified. However, indicators to track these changes are minimal. This paper analyzes the regulatory and organizational frameworks to address environmental management during the planning and construction of hydropower facilities in Mexico and gives recommendations to expand the scope of the supervision and management of ecosystem changes.

Abstract: during the last 2 decades, awareness of neonatal pain is being increased. pain has short and long term adverse effects. babies hospitalized in neonatal intensive care units are exposed to many painful procedures; unfortunately, there is no general consensus in the approach and management of pain in newborns. the objectives of this report are: 1) increase the awareness of neonatal pain among care givers; 2) present most common neonatal pain assessment scales (pipp: premature infant pain profile; cries: crying, requires oxygen to maintain saturation > 95 %, increased vital signs, expression, sleeplessness; nips: neonatal infants pain scale); 3) discuss therapeutic approach to management of pain in newborns.
Antibiotics Shaping Bacterial Genome: Deletion of an IS91 Flanked Virulence Determinant upon Exposure to Subinhibitory Antibiotic Concentrations

Abstract: The nucleoid-associated proteins Hha and YdgT repress the expression of the toxin α-hemolysin. An Escherichia coli mutant lacking these proteins overexpresses the toxin α-hemolysin encoded in the multicopy recombinant plasmid pANN202-312R. Unexpectedly, we could observe that this mutant generated clones that no further produced hemolysin (Hly-). Generation of Hly- clones was dependent upon the presence in the culture medium of the antibiotic kanamycin (km), a marker of the hha allele (hha::Tn5). Detailed analysis of different Hly- clones evidenced that recombination between partial IS91 sequences that flank the hly operon had occurred. A fluctuation test evidenced that the presence of km in the culture medium was underlying the generation of these clones. A decrease of the km concentration from 25 mg/l to 12.5 mg/l abolished the appearance of Hly- derivatives. We considered as a working hypothesis that, when producing high levels of the toxin (combination of the hha ydgT mutations with the presence of the multicopy hemolytic plasmid pANN202-312R), the concentration of km of 25 mg/l resulted subinhibitory and stimulated the recombination between adjacent IS91 flanking sequences. To further test this hypothesis, we analyzed the effect of subinhibitory km concentrations in the wild type E. coli strain MG1655 harboring the parental low copy number plasmid pHly152. At a km concentration of 5 mg/l, subinhibitory for strain MG1655 (pHly152), generation of Hly- clones could be readily detected. Similar results were also obtained when, instead of km, ampicillin was used. IS91 is flanking several virulence determinants in different enteric bacterial pathogenic strains from E. coli and Shigella. The results presented here evidence that stress generated by exposure to subinhibitory antibiotic concentrations may result in rearrangements of the bacterial genome. Whereas some of these rearrangements may be deleterious, others may generate genotypes with increased virulence, which may resume infection.

Abstract: Se realizó análisis fitoquímico y de la actividad antibacteriana del extracto alcohólico de la corteza de Diphysa minutifolia Rose (Leguminaceae), colectada de la Región Tierra Caliente del Estado de Guerrero, México. El estudio químico cualitativo del extracto sugirió la presencia de compuestos reductores, flavonoides, fenoles y taninos. Para determinar su posible efecto antibacteriano, el extracto se enfrentó a 33 cepas bacterianas de la colección ATCC y de otros orígenes por el método de difusión radial en monocapa en medio con agar y con pocillos cilíndricos. La concentración máxima del extracto evaluado fue 100 mg/mL. Se determinó que el extracto alcohólico posee actividad inhibitoria frente al 84,3 % de las cepas bacterianas probadas incluyendo Gram positivas y Gram negativas y que su efecto es bacteriostático y bactericida. Para valores de concentración mínima inhibitoria de 100 mg/ mL, este extracto presentó baja actividad sobre el 37,0 % de las cepas probadas, con valores entre 25 y 50 mg/mL mostró mediana actividad sobre el 29,6 % de las cepas y para valores de concentración mínima inhibitoria inferiores a 12,5 mg/mL, tuvo elevada actividad sobre el 33,3 % de las cepas. El extracto presentó efecto bactericida sobre el 66,6 % de las cepas bacterianas inhibidas (54,4 % del total de cepas ensayadas). Se requieren estudios posteriores para dilucidar la naturaleza de los principios activos de la corteza del tronco de esta planta, responsables de las propiedades antibacterianas del extracto evaluado.
