Abstract: in mexico, medicinal plants are widely used. the use of randia aculeata by healers against snakebites has never been scientifically tested in relation to possible effects on blood parameters and muscle tissue damage. interviews were carried out in jamapa, veracuz, mexico, with local residents to collect information about the traditional use of randia aculeata. in this locality, seven pieces of fruit from the plant are mixed in a liter of alcohol, and then administered orally against snakebites. by using histological techniques and a murine model, we explored its cytoprotective properties against the effects of crotalus simus and bothrops asper venoms. possible protections provided by the plant against tissue damage to skeletal and cardiac muscles and against the typical loss of red blood cells were analyzed. randia aculeata caused an increase in microhematocrit and total hemoglobin, parameters that are often decremented in association with the loss of red blood cells, which is a characteristic effect of animal venom. randia aculeata was also shown to protect against the lowering of platelet levels caused by bothrops asper venom. finally, randia aculeata produced a partial inhibition of necrosis following administration of snake venom in skeletal and myocardial muscles. the present results provide solid evidence for the traditional use of randia aculeata against snakebites, as demonstrated by protection against muscular tissue damage and the diminution of red blood cells.

Abstract: This paper describes a sensory analysis of olive oils from main Tunisian cultivars: Chemlali, Chétoui, Sradki, Sayali and Hor Kesra, and one Spanish cultivar: Arbequina. Some hybrids obtained from controlled crossings between Tunisian and European cultivars: Hd 031, Hd 034, Hd 038, Hd 039, Hd 044 & Hd 045, were also analysed. Sensory evaluation of oils was performed in order to evaluate their sensory profiles. A Duncan Test (a = 0,05) was applied using the data of each attribute and showed differences between analysed oils, pointing out the oil from the hybrids HD 044 for its bitter attribute. All collected data were also submitted to Cluster analysis, based on the similarity in Euclidian distances, showing the difference between the oil from hybrid HD 044 and the rest. Con el fin de definir su perfil organoléptico, se han evaluado sensorialmente seis aceites de oliva virgen procedentes de cinco cultivares establecidos en diferentes zonas de Túnez: Sayali, Sradki, Hor Kesra, Chétoui y Chemlali, y un cultivar de la provincia de Badajoz (Espa a): Arbequina; así como los procedentes de seis cultivares híbridos igualmente establecidos en Túnez: Hd 031, Hd 034, Hd 038, Hd 039, Hd 044 y Hd 045. Un test de Duncan (a = 0,05), teniendo en cuenta las puntuaciones dadas a los diferentes atributos evaluados, permite observar diferencias entre los aceites estudiados, destacando la encontrada entre el aceite procedente del híbrido Hd 044 de los restantes por su nivel de amargo. Así mismo, un análisis de Cluster, muestra la similitud entre ellos, teniendo en cuenta esos mismos atributos, observándose una clara diferencia entre el aceite con origen en el híbrido Hd 044 y los restantes.

Hidalgo Gallardo Amada, Hidalgo Gallardo Ruth Leticia
Journal of Human Resource and Sustainability Studies (JHRSS) , 2016, DOI: 10.4236/jhrss.2016.41003
Abstract: Due to the accelerated economic liberalization, the environment has been damaged by the high and constant emission of CO2, phenomenon that produces global warming as well as greenhouse effect. These processes have a direct influence in land, water and air; the influence on seas is detected on the natural resource of fish and seafood, which tends to change their geographic status, mutation and extinction of the specie. This article has the purpose to reflect on the importance about the marine natural resources conservation since they are food products with high protein and worldwide consumption rates. Because of this, the present investigation aims to elaborate a descriptive analysis based on the Complex Interdependence Theory in the fishing industry during the period 2006-2013. This analysis has showed that the productivity of the resource presents unbalances in characteristics, regulation, production and trade, for what it is necessary the restructuring of the fisheries sector with reinforced and strict regulation of the activity to face this item delay.

Abstract: since ancient times, traditional medicine has widely used species of the genus lippia as analgesics, anti-inflammatory, antipyretic, antifungal, etc. numerous studies describe several compounds present in aqueous extracts, methanol, or essential oils of these plants, being flavonoids the most abundant compounds. however, the composition and quantity of secondary metabolites depend on the geographical area, climatic factors, altitude, time of harvest and growth status of these plants. the objective of this study was to evaluate the antioxidant activity of aqueous extract of oregano (lippia graveolens hbk) from the north of mexico and its toxic effect in vitro and in vivo. the antioxidant activity of the aqueous extract was measured by dpph method in six dilutions of the extract (5-160 mg / ml), trolox was used as a reference. for the in vitro toxic effect, cytotoxicity assay with larvae of artemia salina was used. for the in vivo effect, 24 males mice were used and divided into 6 groups (n = 4): 4 experimental groups with 10, 100, 1000 and 5000 mg extract / kg body weight administered orally respectively, also we used a group positive control (5 mg of colchicine / kg body weight administered via ip) and a negative control group (distilled water only). after treatment all mice were sacrificed, and samples from liver and kidney were collected and analyzed by histological and histochemical studies. also a quantitative analysis was done. the antioxidant activity of aqueous extract of oregano was presented at 160 mg/ml. the lc50 was greater than 1.000 mg/ml, so the extract is considered nontoxic. in the morphological analysis in vivo with different doses of aqueous extract of oregano, no toxic effect was observed. the results validate the use of oregano in traditional medicine.

Abstract: a descriptive study of 80 patients with attempted suicide from january 1997 to december 2000 was undertaken. these patients had been admitted to the psychiatry service of "dr octavio de la concepción y de la pedraja" military hospital. the 17-23 years-old group was predominant. the psychopathological profile comprised anxiety, suicidal ideas, sadness and insomnia. the personality profile from the implementation of the 16 pf allowed characterizing the group as persons with emotional instability, unconfident, apprehensive, anxious, stressed, frustrated, highly anxious. drug poisoning was the most used method to commit suicide. the incidence of the family history of attempted suicides and psychiatric disorders was high. among the psychiatric diseases, anxious and depressive situational disorders were the number one.
Will the International Community Maintain the Marino Resource before the Environmental Ravages?  [PDF]
Hidalgo Gallardo Amada, Hidalgo Gallardo Ruth Leticia, Cruz Cruz Mario
Journal of Human Resource and Sustainability Studies (JHRSS) , 2016, DOI: 10.4236/jhrss.2016.42014
Abstract: This article is intended to publicize the damage caused by the environment in natural resources, in this case fishery. This analysis addresses the international regulation and the proposal for the Kyoto Protocol to which the States must refer to both to improve the environment and to conserve the natural resources. This analysis is subject to a descriptive analytical study based on the complexity, sensitivity and vulnerability of economic acceleration in environmental effects on air, land and water. The exercise was a comparison between the European Union, Morocco and Mexico, in the 2006-2013 period, in the application of international norms in its internal policies, the problems that each of these countries faced for damages to the marine resource and how these were addressed, to reach clear and compelling results. In the analysis, we argue that, despite all the strategies in the different areas-titles, the results are not the expected, since the States and mainly the natural resources, depend on other key elements for the effectiveness in the phenomenon.
La citación en tesis doctorales de biología y lingüística
Gallardo,Susana;
íkala, Revista de Lenguaje y Cultura , 2010,
Abstract: objective: to identity differences among disciplines in using citation. methodology: through a qualitative analysis we have studied the forms and functions of citations in two sections (''introduction'' and ''conclusions'') of doctoral theses of biology and linguistics. on the one hand, we have explored the lexis and grammar so to determine the form of citations in different rhetorical moves. on the other hand, from a pragmatic point of view we have determined the place of the referred content in the illocutionary structure. results: we observed a correlation between the form of citations and function of segment or movement in which they appear. in the discussion section of biology thesis, citation played the role of enablement or justification of claims. these results suggest that authors in biology need to support their conclusions with evidence from other investigations. conclusions: in our opinion, the differences between disciplines are related with different epistemological conceptions.

Abstract: the cinema is one ofthe visual media ofmore influence in the circulation of valúes and beliefs in the contemporary world. it is a cultural practice that has remained in the margins ofthe anthropology. however, new relative interests to the understanding in the ways of seeing, it has allowed us to investígate with certain depth in the operations ofthis domain and their visual devices. this article described the devices and visual procedures to native representations a chilean cinema fiction. our results suggest the presence a cultural strategy whose representations don 't try with the cultural diversity, but rather they appear as a utopian way of imagining the social world.
HISTORIA DEL PENSAMIENTO ECONóMICO Y PROGRESO DE LA CIENCIA ECONóMICA. UNA PERSPECTIVA PLURALISTA
Gallardo,álvaro;
Cuadernos de Economía , 2004,
Abstract: the need for theoretical pluralism and the history of economic thought as the driving force behind such methodological perspective arises from current economics' lack of support and empirical justification. this article proposes a view of the history of economic thought adapted for fulfilling this function, given that perspectives concerning the history of economic thought are insufficient for fluffing such demands from an orthodox viewpoint.
Genome dynamics, genetic complexity and macroevolution
GALLARDO,MILTON;
Revista chilena de historia natural , 2003, DOI: 10.4067/S0716-078X2003000400013
Abstract: genome data analysis indicates that the major evolutionary transitions have been driven by substantial increases in genomic complexity. these increases, accounting for novelty in evolution, have proceeded mainly by gene duplication. this idea, advanced by ohno (1968), remains current in the study of several organisms whose genomes have been sequenced. maize, yeast, and humans contain more paralogons than would be expected to occur by chance, and this supports the contention that gene families were not formed de novo, but by large-scale dna duplications. lineage hybridization emerges as an efficient and widespread mechanism to create evolutionary novelty by recruiting redundant genes to new roles. lateral gene transfer indicates a chimeric composition of prokaryote genomes. this peculiar manner of inheritance blurs the edges of phylogenetic lineages and suggests that the anastomosing and dichotomization of branches play key roles in determining the shape of the tree of life. adaptive mutations have also enlarged the genetic framework of evolutionary thought by incorporating a new mechanism of gene formation. moreover, developmental biology has provided solid grounds for understanding organisms as consisting of onto- and epigenetically organized modules. rapid and drastic changes brought about by the study of developmental genes have discredited the notions that adaptation is achieved exclusively by stepwise allele replacement within populations, and that macroevolutionary change is extrapolated microevolution. apparently, a broadening, if not a remodeling of the genetic framework in which we understand phylogeny and the evolution of morphological complexity, is emerging through the study of comparative genomics
