A importância da atenção farmacêutica após a verificação da qualidade microbiológica de medicamentos contendo paracetamol encontrados em algumas residências de Américo Brasiliense - SP

It is known that a high microbial count can compromise the stability of medicines, thus reducing their therapeutic efficacy. This work tried to demonstrate that the microbial contamination can be directly related to the inadequate handling of the medicines stored in homes, making it possible to draw strategies to reduce the possible risks of medical therapy offering correct information and advising. The objective of this work was to evaluate the quality of the medicines containing paracetamol found in the residences of Américo Brasiliense-SP, using the microbial analysis of non-sterile method described in the Brazilian Pharmacopoeia (1988). The medicine samples (30 samples) were obtained directly from the interviewed local residents, who had received new medicine bottles of the same product. An analysis of viable microorganisms (bacteria and fungus) was carried out to identify pathogens found in the collected samples. Although 90% of the analyzed samples have shown some microbial contamination, the results indicated the absence of pathogenic microorganisms, and the total count of viable microorganisms was below the maximum value for non-sterile (104 UFC/g or mL). It was also verified that the local residents stored the medicines in appropriate places, according to the orientations received when they bought the medicines in pharmacies and drugstores, showing the importance of information for the correct use and conservation of pharmaceuticals.

Climate warming and vegetation response after Heinrich event 1 (16 700–16 000 cal yr BP) in Europe south of the Alps

Chironomids preserved in a sediment core from Lago di Origlio (416 m a.s.l.), a lake in the foreland of the Southern Swiss Alps, allowed quantitative reconstruction of Late Glacial and Early Holocene summer temperatures using a combined Swiss–Norwegian temperature inference model based on chironomid assemblages from 274 lakes. We reconstruct July air temperatures of ca. 10 °C between 17 300 and 16 000 cal yr BP, a rather abrupt warming to ca. 12.0 °C at ca. 16 500–16 000 cal yr BP, and a strong temperature increase at the transition to the Bølling/Allerød interstadial with average temperatures of about 14 °C. During the Younger Dryas and earliest Holocene similar temperatures are reconstructed as for the interstadial. The rather abrupt warming at 16 500–16 000 cal yr BP is consistent with sea-surface temperature as well as speleothem records, which indicate a warming after the end of Heinrich event 1 (sensu stricto) and before the Bølling/Allerød interstadial in southern Europe and the Mediterranean Sea. Pollen records from Origlio and other sites in southern Switzerland and northern Italy indicate an early reforestation of the lowlands 2000–1500 yr prior to the large-scale afforestation of Central Europe at the onset of the Bølling/Allerød period at ca. 14 700–14 600 cal yr BP. Our results suggest that these early afforestation processes in the formerly glaciated areas of northern Italy and southern Switzerland have been promoted by increasing temperatures.

Paleolimnological evidence for increased landslide activity due to forest clearing and land-use since 3600 cal BP in the western Swiss Alps

Schwarzsee is located in the western Swiss Alps, in a region that has been affected by numerous landslides during the Holocene, as evidenced by geological surveys. Lacustrine sediments were cored to a depth of 13 m. The vegetation history of the lake's catchment was reconstructed and investigated to identify possible impacts on slope stability. The pollen analyses record development of forest cover during the middle and late Holocene, and provide strong evidence for regional anthropogenic influence such as forest clearing and agricultural activity. Vegetation change is characterized by continuous landscape denudation that begins at ca. 4300 cal. yrs BP, with five distinct pulses of increased deforestation, at 3650, 2700, 1500, 900, and 450 cal. yrs BP. Each pulse can be attributed to increased human impact, recorded by the appearance or increase of specific anthropogenic indicator plant taxa. These periods of intensified deforestation also appear to be correlated with increased landslide activity in the lake's catchment and increased turbidite frequency in the sediment record. Therefore, this study gives new evidence for a strong influence of vegetation changes on slope stability during the middle and late Holocene in the western Swiss Alps, and may be used as a case study for anthropogenically induced landslide activity.

El consulado de Camilo José Cela en las cartas a Américo Castro

En 2009, se publicó el libro Correspondencia con el exilio que reúne cartas intercambiadas entre Camilo José Cela y escritores españoles exiliados a causa de la Guerra Civil Española y de la dictadura franquista. En total, hay 839 cartas escritas o recibidas por Cela, que pueden ser leídas y analizadas en conjunto o separadamente, por interlocutor, formando subconjuntos. Uno de esos subconjuntos está formado, precisamente, por las cartas intercambiadas entre Cela y Américo Castro y se constituye en el corpus de este trabajo. Dos motivaciones están por detrás de nuestra opción: por un lado, se trata del más intenso diálogo en lo que dice respecto a la cantidad de cartas y, tal vez se pudiera decir, a los temas discutidos; por otro lado, las cartas dan cuenta de la construcción de diferentes tipos de lazos, incluso del (para algunos increíble) lazo de amistad. Nuestro objetivo es reflexionar sobre tales vínculos, a partir de las cartas de Cela -que nos desvelan aspectos de su papel como editor, escritor y amigo-, porque entendemos que se articulan formando lo que el escritor gallego presenta como su consulado para atender a los intelectuales y escritores que vivían en el exilio
