La odontología como ciencia biológica difiere del pensamiento jurídico en numerosos puntos. La biología es a menudo variante. Por lo tanto el razonamiento biológico lleva implícito una parte de reserva, de incertidumbre y de duda. Por el contrario el pensamiento jurídico tiene que responder a los textos que lo instituyen como los códigos y las leyes, que son de elaboración humana, por lo tanto discernibles y asimilables. Desde la época que el hombre realizaba investigaciones empíricas, hasta nuestros días, han concurrido ciencias y disciplinas de investigación que han generado el crecimiento de diferentes especialidades, aportando elementos que definen y caracterizan su campo de acción. La Odontología Legal, como cualquier rama de la ciencia, es un producto de la evolución del hombre. Por lo tanto varía con el tiempo, es distinta según los estados o los países. El Derecho moderno establece una colaboración entre la ciencia y la ley. En estos casos el grado de responsabilidad del odontólogo es alto, porque tiene la función de auxiliar con sus conocimientos, donde sus dichos pueden influir con fuerza sobre el fallo del magistrado. Es preciso, actualmente que el perito odontólogo, adquiera un cúmulo de conocimientos sobre el espíritu jurídico y los procedimientos a seguir en los distintos fueros.Facultad de Odontología (FOLP

Complex relationship between amino acids, fitness and food intake in Bombus terrestris

The ratio of amino acids to carbohydrates (AA:C) that bumble bees consume has been reported to affect their survival. However, it is unknown how dietary AA:C ratio affects other bumble bee fitness traits (e.g., fecundity, condition) and possible trade-offs between them. Moreover, while individual AAs affect phenotype in many species, the effects of AA blend on bumble bee fitness and food intake are unclear. We test how the AA:C ratio that bumble bees (Bombus terrestris) consume affects their condition (abdomen lipid and dry mass), survival following food removal, and ovarian activation. We then compare ovarian activation and food intake in bees fed identical AA:C ratios, but where the blend of AAs in diets differ, i.e., diets contained the same 10 AAs in an equimolar ratio or in the same ratio as in bee collected pollen. We found that AA:C ratio did not significantly affect survival following food removal or ovarian activation; however, high AA intake increased body mass, which is positively correlated with multiple fitness traits in bumble bees. AA blend (i.e., equimolar versus pollen) did not significantly affect overall ovarian activation or consumption of each experimental diet. However, there was an interaction between AA mix and dietary AA:C ratio affecting survival during the feeding experiment, and signs that there may have been weak, interactive effects of AA mix and AA:C ratio on food consumption. These results suggest that the effect of total AA intake on bumble bee phenotype may depend on the blend of individual AAs in experimental diets. We suggest that research exploring how AA blend affects bumble bee performance and dietary intake is warranted, and highlight that comparing research on bee nutrition is complicated by even subtle variation in experimental diet composition

The effects of levetiracetam on urinary 15f-2t-isoprostane levels in epileptic patients

Purpose: We aimed to investigate the effects of levetiracetam on oxidative stress which is one of the new antiepileptic drugs in epileptic patients

Propolis protects endotoxin induced acute lung and liver inflammation through attenuating inflammatory responses and oxidative stress

WOS: 000431372400001PubMed: 29719160Propolis is a natural bee product, and it has many effects, including antioxidant, anti-inflammatory, antihepatotoxic, and anticancer activity. In this study, we aimed to explore the potential in vivo anti-inflammatory, antioxidant, and antiapoptotic properties of propolis extract on lipopolysaccharide (LPS)-induced inflammation in rats. Forty-two, 3- to 4-month-old male Sprague Dawley rats were used in six groups. LPS (1mg/kg) was administered intraperitoneally to rats in inflammation, inflammation + propolis30, and inflammation+propolis90 groups. Thirty milligram/kilogram and 90mg/kg of propolis were given orally 24 h after LPS injection. After the determination of the inflammation in lung and liver tissues by F-18-fluoro-deoxy-d-glucose-positron emission tomography ((18)FDG-PET), samples were collected. The levels of malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), nitric oxide (NO), and DNA fragmentation were determined. The decrease of MDA levels in inflammation + propolis30 and inflammation + propolis90 groups was determined compared to the inflammation group in lung and liver tissues. The increase of SOD% inhibition in inflammation + propolis90 group was determined in liver, lung, and hemolysate compared to the inflammation group. Increased CAT activities in inflammation + propolis30 and inflammation + propolis90 groups were observed in liver tissue and hemolysate compared to inflammation group. In lung tissue, NO levels were lower in inflammation group compared to the control group, but DNA fragmentation levels were higher. F-18-FDG uptake of tissues in inflammation + propolis30 and inflammation + propolis90 groups was decreased compared to the inflammation group. In conclusion, the data of this study indicate that the propolis application may serve as a potential approach for treating inflammatory diseases through the effect of reducing inflammation and free oxygen radical production
