Comparative Analysis of Lactulose and Fructooligosaccharide on Growth Kinetics, Fermentation, and Antioxidant Activity of Common Probiotics  [PDF]
Evelyn Lu, Marie Yeung, Chi Kong Yeung
Food and Nutrition Sciences (FNS) , 2018, DOI: 10.4236/fns.2018.93013
Abstract: Prebiotics are non-digestible oligosaccharides that selectively stimulate the growth of beneficial bacteria in the human gut. Fructooligosaccharide (FOS) is a common prebiotic found in food products and infant formula. Lactulose is primarily used as a pharmaceutical ingredient but also shows potential prebiotic activities. Our objectives were to determine and compare the effects of FOS and lactulose on: 1) growth kinetics of common probiotics in aerobic condition; 2) pH and titratable acidity after fermentation; and 3) antioxidant capacity of the probiotics. Ten probiotic and two non-probiotic strains, representing genera Lactobacillus, Bifidobacterium, Bacillus, and Escherichia were assembled. Media used for prebiotics experiment were modified to contain 2% FOS or lactulose as the sole or main carbohydrate source. All experiments were done in triplicate. In aerobic condition, most strains cultured with FOS or lactulose did not grow optimally compared to dextrose (a non-prebiotic), while all four Bifidobacterium spp. showed little growth regardless of the carbohydrate source. In anaerobic condition, lactulose and FOS fermentation of Bifidobacterium spp. yielded similar pH (p = 0.2723), but percent lactic acid, as determined by titratable acidity, was higher after lactulose fermentation (p = 0.0004). The non-probiotic strains were able to utilize both FOS and lactulose, but displayed weaker acid production and higher pH (p < 0.0001) relative to the probiotic strains. Antioxidant activity of spent medium was measured with Trolox as the reference standard. Overall, the antioxidant activity of probiotics was strain-dependent. FOS enhanced the antioxidant activity of Bifidobacterium spp. (p = 0.0002) and Lactobacillus spp. (p = 0.0447), but not probiotic E. coli and Bacillus spp. (p = 0.2599) or non-probiotics (p = 0.8816). In conclusion, lactulose supported growth activities of probiotics to a similar extent as FOS. Lactulose also stimulated higher acid production for Bifidobacterium spp. than FOS in anaerobic condition, thus it might be considered for incorporation into functional food products containing bifidobacteria.
Desempenho do exame colpocitológico com revis o por diferentes observadores e da captura híbrida II no diagnóstico da neoplasia intra-epitelial cervical graus 2 e 3

Cadernos de Saúde Pública , 2003,
Abstract: Para avaliar o desempenho da colpocitologia (CO) de encaminhamento e daquela coletada no servi o de referência, com revis o por diferentes técnicas e observadores, e da captura híbrida II (CH II) no diagnóstico da neoplasia intra-epitelial cervical (NIC) de alto grau, foram incluídas 105 mulheres atendidas entre agosto de 2000 e junho de 2001 por atipias pré-neoplásicas na CO. Todas foram submetidas à coleta de nova CO e CH II para detec o do DNA-HPV. Foi realizada biópsia cervical em 91, sendo o diagnóstico histológico considerado padr o ouro. Foram descritas a sensibilidade, especificidade e raz o de verossimilhan a positiva (RVP) dos métodos propedêuticos com intervalo de confian a de 95% (IC95%). A sensibilidade e especificidade da CO de encaminhamento foi de 57% e 82% para o diagnóstico de NIC 2 e 3, e a RVP de 3,2 (IC95%: 1,5-6,8). A CO do servi o mostrou uma sensibilidade e especificidade 79% e 84%, respectivamente e RVP de 5,0 (IC95%: 2,5-10,0). A sensibilidade (86%), especificidade (80%) e RVP (4,3) foram semelhantes com a revis o lenta realizada pelo segundo observador, havendo uma queda significativa da sensibilidade (64%) à revis o rápida pelo terceiro observador. A CH II mostrou alta sensibilidade (100%), baixa especificidade (43%) e baixa RVP (1,7, IC95%: 1,4-2,2).
Dental Treatment with 30% Trichloroacetic Acid in a Patient with Moderate Hemophilia A  [PDF]
Evelyn Gonzalez Delgado, Gianluca Sottilotta
Open Journal of Blood Diseases (OJBD) , 2013, DOI: 10.4236/ojbd.2013.31003
Abstract:

We present the case of a 51-year-old moderate hemophiliac with gingival bleeding due to papillary inflammation and adherence in the molar area 47. After dental diagnosis a calculus was removed and 30% trichloroacetic acid was placed by a pressurized applicator for five seconds; the procedure was repeated until the bleeding stopped, then tranexamic acid was placed by a gauze. The patient chewed the gauze for 30 minutes and was discharged after repeating the same procedure for 30 minutes more. We observed how local treatment with trichloroacetic acid combined to tranexamic acid placed on the hemorrhagic site was able to stop the bleeding.

Aspectos de la biología y hábitat de un pez endémico de Chile en peligro de extinción (Diplomystes nahuelbutaensis ARRATIA, 1987)
Habit,Evelyn;
Interciencia , 2005,
Abstract: diplomystes nahuelbutaensis es una especie endémica de chile, poco abundante y clasificada en peligro de extinción. la planificación de estrategias para su conservación tiene como restricción la falta de conocimiento sobre su biología. en este trabajo se analizan las variaciones espaciales y temporales de la talla y factor de condición, y su relación con variables del hábitat en tres cuencas (laja, rucúe e itata), con énfasis en el río laja (cuenca del río biobío). la talla presenta una distribución multimodal, con cuatro grupos modales, dos bajo la talla mínima de madurez sexual (110mm lt). los adultos de primavera y de la cuenca del río itata son más grandes, en tanto que los juveniles presentan mayor talla en invierno, sin diferencias entre cuencas. en cuanto al hábitat, la principal segregación entre adultos y juveniles sucede debido a la velocidad de la corriente y profundidad máxima, estando los adultos en aguas más torrentes y profundas.
Tras las huellas del guionista: La mirada de Rafael Azcona sobre Martina en Son de mar
Hafter,Evelyn;
Olivar , 2008,
Abstract: the novel of manuel vicent, son de mar, has been adapted to the cinema by the director bigas luna, with script of rafael azcona. in the passage of the literary work to the film the personage of martina undergoes certain changes that can be explained from the intervention of this last one. the protagonist registers in a series of women who in the universe of the scriptwriter in front of share certain characteristics and attitudes, specially, in front of the man, so that is legitimate to speak of the azconization of the wife of the professor of classic.
Factors in Overcoming Barriers to Implementing Co-management in British Columbia Salmon Fisheries
Evelyn Pinkerton
Ecology and Society , 1999,
Abstract: Ten years of research and efforts to implement co-management in British Columbia fisheries have demonstrated that we lack neither good models nor the political will in communities to design and test local and regional institutions for successful involvement in various aspects of management. The barriers lie rather in the distrust and resistance of management agencies and the lack of broadly organized political support. The nature of the barriers and some of the elements of a successful approach to overcoming them are identified and discussed. The analysis is focused around the barriers encountered by two differently situated fishing communities or regions that have launched conservation initiatives through cooperation between local aboriginal and nonaboriginal fishing groups. In attempting to overcome the political barriers, the communities seek to develop expertise in selective fishing technology for more sustainable harvest, principled multi-stakeholder negotiation, marketing, shared databases, and preliminary ecosystem monitoring. The communities exemplify small- and medium-scale bottom-up approaches to adaptive management. The analysis shows the key and possibly unique contributions of processes at these levels, and suggests how they can be scaled up and linked to processes at other levels. Both types of analysis are largely missing in adaptive management theory, which has tended to focus on larger scale processes and to dismiss the potential of smaller scale ones to transform, expand, and link. This analysis focuses on salmon (Oncorhynchus spp.) fisheries of British Columbia, Canada, but the literature suggests that the findings have far broader applicability.
