Influence of Ethanol on Probiotic and Culture Bacteria Lactobacillus bulgaricus and Streptococcus thermophilus within a Therapeutic Product  [PDF]
Behannis Mena, Kayanush J. Aryana
Open Journal of Medical Microbiology (OJMM) , 2012, DOI: 10.4236/ojmm.2012.23010
Abstract: Probiotic bacteria in plain yogurt namely of Lactobacillus ssp. have been reported to treat thrush, diarrhea, athlete’s foot, jock itch and vaginal yeast infections. Lactobacillus delbrueckii ssp. bulgarius (LB-12) and Streptococcus thermophilus (ST-M5) are lactic acid bacteria widely used in the manufacture of yogurt. Alcohol is used in manufacture of some medications such as cough syrups and some products such as eggnog and rum-raisin ice cream. The objectives were to study the effect of food grade ethanol on the growth of yogurt culture bacteria and the physico-chemical characteristics of therapeutic yogurt. The treatments were 0% (control), 2.5%, 5%, and 7.5% v/v ethanol in plain yogurt. The ethanol was incorporated by stirring it into one day old plain yogurt. Product characteristics were studied weekly for a month of refrigerated (4?C) storage. Data were analyzed using Proc Mixed model of Statistical Analysis System. The ethanol amount × storage period interaction effect was significant for Lactobacillus bulgaricus counts while the ethanol amount × storage period effect was not significant for Streptococcus thermophilus counts, viscosity, pH and titratable acidity (TA). Therapeutic yogurts with ethanol, at these concentrations, can successfully be manufactured without adversely influencing counts of its probiotic bacteria over product shelf life.
Oxidative Stress Induced Mechanisms in the Progression of Periodontal Diseases and Cancer: A Common Approach to Redox Homeostasis?
Mena Soory
Cancers , 2010, DOI: 10.3390/cancers2020670
Abstract: There is documented evidence of significant associations between cancer of the lung, kidney, pancreas, hematological and oral cancers and periodontal diseases of the supporting structures of the teeth. Enhanced lipid peroxidation, raised levels of TBARS and the oxidative stress marker malondealdehyde have been detected in breast cancer with reduced antioxidant capacity, also characteristic of periodontal diseases. Antioxidants could overcome this deficit and attenuate disease progression by down regulating glutathione detoxification/redox buffering system and inhibiting key transcription factors. Periodontal disease may be a critical marker of a susceptible immune system, or initiate cancer risk with a pro-oxidant inflammatory profile.

Abstract: ssociation of periodontitis with rheumatoid arthritis and atherosclerosis: Novel paradigms in etiopathogeneses and management? Review (5491) Total Article Views Authors: Mena Soory Published Date May 2010 Volume 2010:2 Pages 1 - 16 DOI: http://dx.doi.org/10.2147/OARRR.S10928 Mena Soory King’s College London Dental Institute, Denmark Hill, London UK Abstract: There is increasing documentation of a link between inflammatory periodontal disease affecting the supporting structure of teeth, rheumatoid arthritis, and coronary artery disease. Periodontitis is initiated predominantly by Gram-negative bacteria and progresses as a consequence of the host inflammatory response to periodontal pathogens. Lipopolysaccharide, a cell wall constituent stimulates the production of inflammatory cytokines via the activation of signaling pathways perpetuating inflammatory pathogenesis in a cyclical manner in susceptible individuals; with an element of autoimmune stimulation, not dissimilar to the sequential events seen in RA. Periodontitis, also implicated as a risk factor for cardiovascular disease, promotes mechanisms for atherosclerosis by enhancing an imbalance in systemic inflammatory mediators; more direct mechanisms attributed to microbial products are also implicated in both RA and atherogenesis. Severe periodontal disease characterized by clinical and radiographic parameters has been associated with ischemic stroke risk, significant levels of C-reactive protein and serum amyloid A, amongst others common to both periodontitis and atherosclerosis. Existing data supports the hypothesis that persistent localized infection in periodontitis may influence systemic levels of inflammatory markers and pose a risk for RA and atherosclerosis. A common nucleus of activity in their pathogeneses provides novel paradigms of therapeutic targeting for reciprocal benefit.
Chronic Periodontitis as a Risk Marker for Systemic Diseases with Reference to Cardiometabolic Disorders: Common Pathways in their Progression

Immunology and Immunogenetics Insights , 2012, DOI: 10.4137/III.S5795
Abstract: Periodontitis, an inflammatory condition of the supporting structures of teeth resulting from dental plaque biofilm attached to tooth surfaces is potentially an important nidus of systemic inflammation and its sequelae. Relevant risk markers common to periodontitis co-existing with coronary heart disease and diabetes mellitus play an important role in their pathogeneses and abate in response to treatment. An over-exuberant host-response to periodontal pathogen- mediated inflammation, triggers a cycle of events which is not dissimilar to an autoimmune response in a cohort of susceptible individuals. Some variation in documented findings regarding correlations with co-morbidities and periodontitis could be explained by the lack of uniformity in studies with regard to stipulation of periodontal inflammatory status in the context of risk factors examined. There are several genetic and environmental factors which influence the progression of inflammatory periodontitis in response to plaque biofilm, also relevant to associated cardiometabolic disorders in the same subject. Some common mechanisms in the pathogeneses of periodontitis and cardiometabolic disorders based on regulation of inflammation are addressed in this review. There is some evidence of an improved systemic inflammatory profile in response to periodontal treatment which emphasizes the importance of periodontal management for systemic health in relevant cases.
Optimisation of future long baseline neutrino experiments
Mena, Olga
High Energy Physics - Phenomenology , 2008,
Abstract: The aim of this talk is to review near and far future long baseline neutrino experiments as superbeams, beta-Beams and neutrino factories, comparing their sensitivities to the unknown parameters in the neutrino oscillation sector. We focus on the extraction of the neutrino mass hierarchy, exploring alternatives to the commonly used neutrino-antineutrino comparison. Special attention to a new concept of neutrino factory design, the low energy neutrino factory, is given.
Credit Market Behavior during Turbulent Economic Environments: An Example for a Latin American Country Credit Market Behavior during Turbulent Economic Environments: An Example for a Latin American Country
Hugo Mena
Revista de Análisis Económico (RAE) , 1999,
Abstract: The variability of the economy's growth in Latin American Countries (LACs) tends to far exceed that found in developed nations. Huge recessions are frequent in LACs. Typically, these recessions are accompanied by major exchange-rate-policy breakdowns. In turn, these output and exchange rate changes drastically alter private expectations concerning the future behavior of these variables. As a result, discrete and significant changes in private behavioral functions occur. This typically affects crucial monetary policy indicators, such as interest rates and credit. This turbulent economic environment makes it particularly troublesome for econometricians to test theoretical propositions dealing with credit market behavior, as well as for policymakers to interpret and forecast credit and interest rate behavior. This paper illustrates this issue using Chile as a case study. A simple theoretical model of business credit is developed, which is then used to interpret the developments in Chile's credit market during 1980-1986. Using a partial equilibrium analysis, it is shown how the contemporaneous correlation between output and credit demand can change sign, whenever the economy is subject to unanticipated recessions and devaluations. The analysis is a timely one for policymakers in many LDCs, who are currently on the path of transforming their economies to free-market open-economies.

Restricción paleomagnética para la edad de la formación matasiete Paleomagnetic constrain for the age of the Matasiete Formation
Mabel Mena
Revista de la Asociación Geológica Argentina , 2010,
Abstract: Se presentan los resultados de un estudio paleomagnético de la Formación Matasiete, integrante del Grupo Chubut. Se analizó la estabilidad de las remanencias magnéticas empleando desmagnetización por altas temperaturas y por campos alternos. Estas rocas presentan susceptibilidades magnéticas relativamente altas. Los especímenes estudiados portan componentes viscosas blandas y de bajas temperaturas de desbloqueo cuyas direcciones son estadísticamente coincidentes entre sí y con la dirección que corresponde a un campo dipolar axial y geocéntrico para esa localidad. La remanencia prácticamente desaparece al alcanzar 580oC indicando que la magnetita es el principal portador magnético. En todos los casos se aislaron componentes características con desviaciones angulares máximas <5o. Si bien las pruebas de estructura (fold/tilt tests) resultan indeterminadas dada las actitudes similares de los estratos, el aumento de la concentración de las direcciones de magnetizaciones remanentes características al aplicar la corrección por estructura sugiere que estas remanencias son pretectónicas. A partir de las magnetizaciones se calcularon los polos geomagnéticos virtuales, todos ellos de polaridad normal, y el polo paleomagnético (PP) para la Formación Matasiete (84.7oS, 161.2oE, número de muestras n=34, k=17.51, A95=6.1). La ubicación de este PP es equivalente a las de los PP de las Formaciones Cerro Barcino (112-125 Ma) y Los Adobes (112-130 Ma), aflorantes en Patagonia Central. Esta coincidencia en ubicación apoya la edad hauteriviana?-barremiana-aptiana, asignada en trabajos previos a la Formación Matasiete, sobre la base de asociaciones fosilíferas. Sin embargo la polaridad normal de todos los polos geomagnéticos virtuales sugiere que estas rocas se formaron durante el supercron cretácico normal por lo que se propone una edad aptiana para la Formación Matasiete. The results of a paleomagnetic study performed over the Matasiete Formation, belonging to the Chubut Group, are presented. Alternating field and thermal demagnetization techniques were employed to analyze the stability of the magnetic remanence. The studied specimens have relatively high magnetic susceptibilities. They have soft viscous and low unblocking temperature components. These components are statistically coincident with each other and with the geocentric axial dipole field direction for the locality. The magnetic remanences were removed below 580oC, indicating that magnetite is the main remanence carrier. Characteristic remanent magnetization directions were determined by principal component analy
