Hale (common greenshield lichen) is an Ascomycete, foliose lichen usually growing on tree bark in most mesophytic-forested habitats in Romania. Lichen samples were collected from three stations in Romania (Craiova, Timișoara, Hoia-Baciu Forest, Cluj) and extracted in 96% ethanol. Both dry lichen tissue powder and extracts were analyzed by UV-Vis spectrophotometry for determining photosynthetic pigment concentrations (chlorophylls a and b and total carotenoids). Dry tissue samples had chlorophyll a concentrations of 95.12-109.59 mg/kg DW, chlorophyll b concentrations of 88.53-110.98 mg/kg and total carotenoids 88.89-102.85 mg/kg. Alcoholic extracts of fresh lichen tissue showed an extreme variability, with 715.97-10331.50 mg/kg chlorophyll a, 527.77-8124.20 mg/kg chlorophyll b, 1125.72-8714.90 mg/kg carotenoids pigments, with the highest values in samples from Craiova. A lower variability was observed in flavonoid contents, with 461.78-966.02 mg/kg DW in dry powder and 815.56-2734.135 mg/kg in ethanolic extracts. Extracts of lichens from Craiova had a decreased content of total flavonoids compared with the other two lichens ethanol extracts.","PeriodicalId":11935,"journal":{"name":"European Journal of Medicine and Natural Sciences","volume":"101 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87674969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The problem of solubilization of these compounds is generated by their poor solubility in hydrophilic media. Also, when applying local non-steroidal anti-inflammatory drugs (NSAIDs) in the form of ointments, the local concentration of the active substance is much higher than in the untreated tissue. The amount of NSAIDs required to produce a therapeutic effect by topical administration is much lower than in oral administration. Side effects may, however, occur as a local irritation from the time a topical formulation is applied. This paper presents the solubilization tests performed for pharmaceutical compounds of the NSAID class in different hydrophilic media. The test conclusions are useful because their solubility can be increased by using solvents (polar or non-polar) and surfactants. The conclusions of the solubility tests help in choosing solvents in the formulation and technologicalization of semi-solid preparations with topical application.","PeriodicalId":11935,"journal":{"name":"European Journal of Medicine and Natural Sciences","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73870145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We studied a group of 129 patients with carotid disease, and we established a possible relationship with lacunar stroke. Ultrasonography findings were correlated with the presence of lacunar stroke, confirmed by CT scan. Our study demonstrate that carotid plaques number could be a good predictor for lacunar stroke risk.

{"title":"Identity Narrative as an Unconscious Scaffold for Human Autobiography","authors":"A. Novac, M. Tuttle, R. Bota, B. Blinder","doi":"10.26417/929uar53c","DOIUrl":"https://doi.org/10.26417/929uar53c","url":null,"abstract":"Abstract Over the past years, a multi-disciplinary literature on the significance of personal narratives in autobiography and identity has emerged. This subject has been of interest to authors in the fields of humanities, psychology, and medicine alike. In this paper, we are proposing the term Identity Narrative (IdN) to define a cognitive and emotional framework that serves as an implicit (unconscious) scaffolding of memory on which to build human autobiography. The authors first classify narratives into external (universal history, the humanities, culture) and internal (autobiography, based on personal experiences, both directly and indirectly, through identification and education). All philosophy and social commentary has utilized history for the purposes of prediction and meaning-making. Personalities including Aristotle, St. Augustine, Rousseau, Freud, Marx, Spengler, and Benjamin Franklin have reread history to gain insight about human nature. History has inspired the enlightenment and renaissance of a new reality for humanity. It is widely known that history can also be misused to justify aggression and human suffering. The use of history to create deep convictions that annihilate moral imperatives is only possible because of unconsciously consolidated internal narratives, the IdN. IdN is reshaped through life, both by “bottom-up” acquisition of information, as well as a “top-down” learning model, which includes the following circumstances: (a) sudden insight and awareness; (b) experiences with high emotional valence; (c) high frequency of repetition; and (d) prolonged duration of exposure. In this way, IdN, a form of relatively stable unconscious, anoetic memory, provides a “first-person” experience to autobiography. Autobiography then, becomes part of auto-noetic consciousness, the human ability to mentally time travel and have self-knowledge. IdN parallels lifelong growth and development, language acquisition, and maturing of attachment. The extensive brain activation during communication and speech, revealed by neuroimaging studies, will be referred to as the “communication beltway.” We hypothesize that the alternation in activation between the default mode (midline structures) of the brain (previously associated with the Self) and the language brain creates a platform that encodes crucial components of IdN throughout life. In this way, IdN, autobiographical memory, and the language brain are parts of a larger biological substrate of social affiliations.","PeriodicalId":11935,"journal":{"name":"European Journal of Medicine and Natural Sciences","volume":"18 1","pages":"44 - 53"},"PeriodicalIF":0.0,"publicationDate":"2019-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81032118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the past years, it became obvious that the ecosystem presents a marine algae excedent, which should be utilized in one way or another. Marine algae have been intensely studied. The superior exploitation of the marine biomass represents a highly important resource for the pharmaceutical industry, supplying raw material for the extraction of bioactive substances (vitamins, sterols, and aminoacids) and various other substances, the purity of which is strongly connected to the state of the marine ecosystem. In present work the extracts from marine algae are incorporated in type I non-denatured fibrillar collagen matrixes for obtain new pharmaceutical product. In order to obtain therapeutic effects at nanostructure level, it is important to know the rheological characteristics of the relevant mixtures of collagen gels and extracts from marine algae selected for use.

But in a generation, Pacem in Terris posited a nuance that put the preference on the “higher” unit. The capabilities of “higher” units could supersede the rights of “lower” units because the “on reserve” aid from “higher” units leads to more effectivity. Then, applying integral ecology, Laudato Si’ put the preference on the “higher” pole when issues are environmental in character. This stems from an understanding of complex and interconnected mechanisms in the interaction between populations and the environment. Because Nature has predetermined ways of acting and reacting to events like those caused by populations, Nature relays the impact of actions, such as environmental backlash, to other locations, sections, or later generations; it can also “slap back” at the local agents of events. Thus, the default option should be for the “higher” units to act when it comes to researching the complex interconnections of actions at the ecological level. But this option can lead to gaming the deliberations on public policy with questions of uncertainty or risk because valid understanding is needed to guide actions or policies. Perspectives broader than the local in terms of understanding and of values to be shared are needed.","PeriodicalId":11935,"journal":{"name":"European Journal of Medicine and Natural Sciences","volume":"4 1","pages":"103 - 116"},"PeriodicalIF":0.0,"publicationDate":"2018-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73959449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
