Icela Dagmar Barceló-Quintal, Hugo Eduardo Solís-Correa, Julisa García-Albortante, Magdalena García-Martínez, Luis Jesús Osornio-Berthet
Journal of Environmental Protection (JEP) , 2018, DOI: 10.4236/jep.2018.910065
Abstract: The problem of contamination of Lerma River in the State of Mexico, México, has been studied in an integral way, since it is one of the rivers of importance due to its geographical situation in the country. José Antonio Dam is the main receiving body of this river that is being contaminated by, industrial wastewater, of which about 70% is inorganic, as well as discharges municipal and agricultural, driving a lot of material in suspension. This dam acts as a regulator of avenues and its water is used for agricultural irrigation and its sediments are used as sludge to improve agricultural soil in the surroundings. One of the studies that have been carried out is to determine the geochemical distribution of heavy metals in the sediments of this dam, as well as its adsorptive capacity towards different metals. It has been observed that these sediments acts as metal contaminants sequester. Knowing the composition and morphology of these sediments can provide information to understand the mobility of different heavy metals it contains, and potential health risk, which can finally lead to the establishment of purification capacity of this sludge.

Abstract: Un reporte de caso fue realizado en dos pacientes asmáticos tratados con un nuevo producto natural de salud llamado Vimang , un extracto acuoso de la corteza de Mangifera indica L. que ha sido registrado como antioxidante y antiinflamatorio. Una mujer de 39 a os con asma moderada persistente y un hombre de 43 a os con asma severa persistente fueron tratados por vía oral con Vimang (cápsulas 300 mg, una cada ocho horas durante tres meses). En las semanas 0, 6 y 12 se realizaron pruebas funcionales respiratorias y determinaciones de inmunoglobulina E total en suero (IgE), proteína catiónica de eosinófilo (ECP) y la actividad de metaloproteinasa-9 (MMP-9). En ambos pacientes se observó una mejoría en el volumen de espiración forzada (FEV1). Los valores de IgE, ECP y la actividad de MMP-9 decrecieron en ambos pacientes. Estos resultados podrían sentar las bases para la realización de más investigaciones clínicas acerca del uso del Vimang como una alternativa para el tratamiento del asma bronquial.

Gabino Garrido,René Delgado,Yeny Lemus,Dagmar García
Boletín Latinoamericano y del Caribe de Plantas Medicinales y Aromáticas , 2004,
Abstract: Mangifera indica L., en sus diversas partes, constituye una especie ampliamente utilizada en diferentes patologías en la medicina tradicional. En el presente trabajo se presentan diferentes antecedentes de tipo experimental y clínico que constituyen la base de sustentación de un nuevo fitofármaco preparado a partir del extracto de la corteza de Mangifera indica registrado en Cuba bajo la Marca Vimang . Entre sus propiedades farmacológicas más relevantes se encuentran su acción antioxidante, analgésica y anti-inflamatoria. Diferentes estudios clínicos realizados destacan sus efectos terapéuticos: antioxidante en pacientes con VIH-SIDA, contra enfermedades dermatológicas, dolores e inflamaciones locales. Estas propiedades conjuntamente con su bajo índice de toxicidad establecido en estudios de dosis única, dosis repetidas y su falta de genotoxicidad parecen develar un nuevo recurso terapéutico sobre el cual se han centrado los esfuerzos para su evaluación clínica y elucidación de sus mecanismos de acción farmacológicos
New insights in understanding dental caries and periodontal disease: the avalanche model  [PDF]
Peter Gaengler, Ljubisa Markovic, Dagmar Norden, Rainer A. Jordan
Health (Health) , 2009, DOI: 10.4236/health.2009.14042
Abstract: Biology is based on evolution; therefore, eu-kariotes like plants, animals and human beings are living in harmony with their procariote an-cestors. If this is obviously the normal way of life, then pathobiology follows the same basic principles. The highly complex harmony of the living world may be disrupted, and a punctuated disease starts which is different from the health equilibrium. To reflect this biological archetype on the main diseases in dentistry - caries and periodontitis - the avalanche model is being proposed based on scientific and clinical evi-dence. This way of argumentation does influ-ence the strategic planning of preventive and curative programmes in dental research as well as in daily practise.

Abstract: the effect of 2 hemin compounds (hemin-arginine and qf12 ) obtained at the center of pharmaceutical chemistry on the percentage of incorporation of 59 fe in the circulating erythrocytes of normal mice was studied. a statistically significant difference was observed between the 2 groups on the second day (p = 0.022). in the a posteriori tests it was found that the average percentage of incorporation of 59 fe of the group that received qf12 at 6 mg/kg was markedly higher than the one obtained with placebo (p = 0.021), and remarkably higher than the found with hemin-arginine at 3 mg/kg (p = 0.021), and with hemin-arginine at 6 mg/kg (p = 0.016) on the second day after the injection of 59 fe. the obtention of qf12, the first cuban heminic compound, and the success attained in its first preclinical test, allowed to request its patent

Abstract: Background Ewing Sarcoma (EWS) is a mesenchymal-derived tumor that generally arises in bone and soft tissue. Intensive research regarding the pathogenesis of EWS has been insufficient to pinpoint the early events of Ewing sarcomagenesis. However, the Mesenchymal Stem Cell (MSC) is currently accepted as the most probable cell of origin. Materials and Methods In an initial study regarding a deep characterization of MSC obtained specifically from EWS patients (MSC-P), we compared them with MSC derived from healthy donors (MSC-HD) and EWS cell lines. We evaluated the presence of the EWS-FLI1 gene fusion and EWSR1 gene rearrangements in MSC-P. The presence of the EWS transcript was confirmed by q-RT-PCR. In order to determine early events possibly involved in malignant transformation, we used a multiparameter quantitative strategy that included both MSC immunophenotypic negative/positive markers, and EWS intrinsic phenotypical features. Markers CD105, CD90, CD34 and CD45 were confirmed in EWS samples. Results We determined that MSC-P lack the most prevalent gene fusion, EWSR1-FLI1 as well as EWSR1 gene rearrangements. Our study also revealed that MSC-P are more alike to MSC-HD than to EWS cells. Nonetheless, we also observed that EWS cells had a few overlapping features with MSC. As a relevant example, also MSC showed CD99 expression, hallmark of EWS diagnosis. However, we observed that, in contrast to EWS cells, MSC were not sensitive to the inhibition of CD99. Conclusions In conclusion, our results suggest that MSC from EWS patients behave like MSC-HD and are phenotypically different from EWS cells, thus raising important questions regarding MSC role in sarcomagenesis.

Economic Evaluation of Early Peach (Prunus Persica L. batsch) Commercial Orchard under Different Irrigation Strategies  [PDF]
Jesus García García, Jose García Brunton
Open Journal of Accounting (OJAcct) , 2013, DOI: 10.4236/ojacct.2013.24014
Abstract: The main aim of this paper is to evaluate the economic response of different irrigation water levels in an early ripening peach variety. In this sense, we evaluate the economics and overall water use efficiency. The test is designed with 4 irrigation water strategies. The economic indices used that use net margin show that all the alternatives are viable although the control with its Net Margin (NM)/Cost (C) of 23.6% is of particular note. This is followed by R50, the highest deficit treatment, with an
NM/C of 16.0%. The mean production cost was almost identical in the optimal treatment (control) and the R50 deficit treatment, €0.69 and €0.70, respectively.
R50 was the most efficient treatment, with a Water Use Efficiency (WUE) of 5.54 kg·m-3. The NM m-3 as economic efficiency index was the greatest in the control (0.74 € m-3), followed by R50 (0.65 € m-3), while the other treatments were far from these figures. Peach cultivation generates a lot of employment and in all cases the Number of Agricultural Jobs (NAJ) ha-1 was around 0.59. As regards the social efficiency of water, the deficit treatments we applied reached high values in this respect, reaching 181 NAJ hm-3 in R50.

Identification of Functional Subclasses in the DJ-1 Superfamily Proteins
Ying Wei,Dagmar Ringe ,Mark A Wilson,Mary Jo Ondrechen
PLOS Computational Biology , 2007, DOI: 10.1371/journal.pcbi.0030010
Abstract: Genomics has posed the challenge of determination of protein function from sequence and/or 3-D structure. Functional assignment from sequence relationships can be misleading, and structural similarity does not necessarily imply functional similarity. Proteins in the DJ-1 family, many of which are of unknown function, are examples of proteins with both sequence and fold similarity that span multiple functional classes. THEMATICS (theoretical microscopic titration curves), an electrostatics-based computational approach to functional site prediction, is used to sort proteins in the DJ-1 family into different functional classes. Active site residues are predicted for the eight distinct DJ-1 proteins with available 3-D structures. Placement of the predicted residues onto a structural alignment for six of these proteins reveals three distinct types of active sites. Each type overlaps only partially with the others, with only one residue in common across all six sets of predicted residues. Human DJ-1 and YajL from Escherichia coli have very similar predicted active sites and belong to the same probable functional group. Protease I, a known cysteine protease from Pyrococcus horikoshii, and PfpI/YhbO from E. coli, a hypothetical protein of unknown function, belong to a separate class. THEMATICS predicts a set of residues that is typical of a cysteine protease for Protease I; the prediction for PfpI/YhbO bears some similarity. YDR533Cp from Saccharomyces cerevisiae, of unknown function, and the known chaperone Hsp31 from E. coli constitute a third group with nearly identical predicted active sites. While the first four proteins have predicted active sites at dimer interfaces, YDR533Cp and Hsp31 both have predicted sites contained within each subunit. Although YDR533Cp and Hsp31 form different dimers with different orientations between the subunits, the predicted active sites are superimposable within the monomer structures. Thus, the three predicted functional classes form four different types of quaternary structures. The computational prediction of the functional sites for protein structures of unknown function provides valuable clues for functional classification.

Abstract: The yogurt is healthy food, which contains at least 100 million cultures per gram. Probiotic bacteria have been proven to reduce the effects of some gastrointestinal problems, probiotics can greatly reduce lactose intolerance, have also been proven to prevent colon cancers, there are also a natural immune system booster. In our research we detected numbers of lactid acid bacteria in yogurts in slovak market. There were classical yogurts, yogurts with probiotics, yogurts with fat and non fat. We numbered lactid acid bacteria from and after expiration, in agars MRS and Lee′s. In examined yogurts we detected from expiration from 78.107 to 169.107 and after expiration from 59.107 to 133.107 lactic acid bacteria in 1 ml of yogurt. In agreement with Food Codex of SR (2010) of rules all these yogurts satisfy number of lactid acid bacteria.
