On November 5, 2015, the rupture occurred of the Fundão dam of the mining company Samarco, located in the sub-district of Bento Rodrigues-MG, 35 km from the center of the Brazilian municipality of Mariana-MG, approximately 16.000 Olympic pools of mining residue circulated through the district of Bento Rodrigues in a period of only 11 minutes. The plume of this environmental impact extended approximately 800 km in the Rio Doce basin, between Minas Gerais and Espirito Santo. The Ipiranga river, located between Linhares and São Mateus, was one of the last sites affected by the waste from the Doce river basin, having contact with the sea in the Urussuquara-ES restinga, a place that is a nursery of biodiversity, especially the marine and estuarine ichthyofauna, besides being of great importance for artisanal fishing and ecotourism. The present study aimed to monitor the Ipiranga River and Urussuquara Beach for all seasonal seasons, beginning in September 2017 and ending in May 2018, the following variables were analyzed: dissolved oxygen, electrical conductivity, hydrogenation potential (pH), transparent, temperature, depth and total dissolved solids, comparing them to the Resolution CONAMA n°. 357, de 17/03/2005, with the purpose of evaluating the quality of estuarine and marine waters. The results found were alarming and evident foci of negative impacts on the aquatic ecosystem and society dependent on artisanal fishing for their subsistence.

<p>A água é um dos recursos naturais mais preciosos e é indispensável à manutenção da vida. Conhecer a quantidade e a qualidade dos recursos hídricos do país é pressuposto para definição de estratégias que busquem a sua conservação, recuperação e o seu uso racional é meta imprescindível para toda a sociedade. Sabe-se que a<strong> </strong>ocupação e o uso do solo alteram os processos físicos, químicos e biológicos dos recursos hídricos. Não obstante ser o país mais bem aquinhoado em termos percentuais de água doce, sua distribuição geográfica é bastante irregular no Brasil. Regiões como o semiárido nordestino e o Vale do Jequitinhonha mineiro, historicamente enfrentam problemas relacionados à falta d’água. Nos últimos anos essa situação tem piorado, em termos de quantidade e qualidade. Assim, a proposta deste trabalho consiste na avaliação da qualidade das águas superficiais da sub-bacia do rio Capivari no município de Chapada do Norte, Alto Jequitinhonha, nordeste de Minas Gerais.

The present work aimed at evaluating the quality of raw materials destined for animal feed production, as well as the quality of corn produced in different areas of the Minas Gerais State. The study was conducted in a feed mill for poultry, with production capacity of 1,000 t d-1. Samples of corn, soybean, flours, animal meals, and feed, during the year of 2008 were collected for analysis of moisture, acidity, peroxides, crude protein, ethereal extract, and physical classification of the corn for "type". The collection of samples, physical-chemical analysis and classification of corn according to "type" were performed at the Industrial Laboratory and at the Department of Agricultural Engineering of Federal University of Viçosa. It was concluded that: raw materials meet the minimum demands of quality (with regards to physical-chemical and nutritional aspects); the corn grains and some by-products present high indexes of moisture and are subject to microbiological contamination during storage; the corn produced in the different areas of Minas Gerais State can be classified as "type 1" for commercialization.

Modern Era

A quality drug is central to the success of any therapeutic plan. The quality of drug is determined right from the collection to delivery to the patients. The commonest problem involving the medicinal plant stating materials is intentional or unintentional substitution and adulteration owing to multiple reasons like unavailability, higher costs, unfair trade etc. This trend was also present in the olden days, as evident from the concept of substitute drugs (Pratinidhi Dravya) as available in Yogratanakara, Bhavaprakasha and Bhaishajyaratnawali. Therefore, Charka and later Acharyas also have dealt with authentication and standardization of herbal drugs and formulations in detail by using four Pramanas (tools of knowledge) Ch.Vi.8/87. Nowadays the concept of substitution is entirely converted into intentional and unintentional malpractices of adulteration. The established authenticity parameters for plant material identification and standardization like organoleptic, physical, chemical and genetic parameters are relatively inaccessible for routine use. Not withstanding the accuracy and usefulness of these lab parameters and delay in the development of easy to perform parameters for reasonable drug authentication. These adulteration malpractices spoils the market of herbal industries. In this article we discuss about concept of substitution in ancient Ayurveda and at present intentional and unintentional adulteration practices.

Abl Tyrosine Kinase Inhibitor

Cancer treatments can often adversely affect the quality of life of young women. One of the most relevant negative impacts is the loss of fertility. Cyclophosphamide is one of the most detrimental chemotherapeutic drugs for the ovary. Cyclophosphamide may induce the destruction of dormant follicles while promoting follicle activation and growth. Herein, we demonstrate the in vivo protective effect of the allosteric Bcr-Abl tyrosine kinase inhibitor Asciminib on signaling pathways activated by cyclophosphamide in mouse ovaries. We also provide evidence that Asciminib does not interfere with the cytotoxic effect of cyclophosphamide in Michigan Cancer Foundation (MCF)7 breast cancer cells. Our data indicate that concomitant administration of Asciminib mitigates the cyclophosphamide-induced ovarian reserve loss without affecting the anticancer potential of cyclophosphamide. Taken together, these observations are relevant for the development of effective ferto-protective adjuvants to preserve the ovarian reserve from the damaging effects of cancer therapies.

The study looks at the problems facing coastal fishing communities. It highlights the impacts that, in the complex framework of the EU reforms, have manifested themselves on economic activities and on society. The aim of the paper is twofold: to examine small-scale artisanal fishing in an area of Southern Italy in order to develop resilience and diversification and at the same time to outline the profiles of local bluefish buyers to highlight development strategies for the sector. The research carried out through a direct survey by administering a questionnaire to fishermen operating in areas of Southern Italy and the data cross-referenced with the opinions of local consumers. A conjoint experiment, followed by a multiple correspondence analysis and cluster identification, was used to outline the profiles of local bluefish buyers. The results of the analysis reveal that the fish market and the restaurant sector are the main distribution channels preferred by fishermen. Furthermore, fishermen are very sensitive to environmental issues and are willing to collaborate and actively participate in the environmental protection of the sea. Consumers recognise the quality of local bluefish, and they implicitly perceive the sustainability of the method of capture. The results show the need to undertake synergistic actions for the fishing industry, capable of activating marketing strategies adequately to support, promote and develop the sector. The results of the study provide helpful information for food companies in order to better segment their market and target their consumers, as well as to effectively promote their product using brands, certifications and traceability.

Faecal Bacteria

Urban development in coastal areas is intense and leads to the increase of sewage outfall and other negative impacts as consequences. Thus, stringent regulations establishing limits to the microbiological contamination of water and seafood are needed. The objective of this study is to evaluate the usefulness of Enterococci and Thermotolerant Coliform densities in the flesh of mussels Perna perna as an alternative tool for monitoring the microbiological quality of coastal waters. The study also considers allometric relations applied to clearance rates to understand rates of bacterial concentration. Bacterial loads obtained in mussels' flesh were from 50 to 4,300 times greater than in the water sampled in the vicinity of the mussels and some were considered inappropriate for consumption even when the water presented no restrictions. The mean clearance rate obtained for Enterococci retention was 317.7 ml h-1 and this rate (CR) is related to the mussels' size (L) by the equation CR = 28.3229L1.6421. The results showed that bacterial densities in the mussels' tissues may reflect chronic contamination of the environment and that clearance rates are important for taking the best decision in situations where, for example, it is desired to introduce mussels for aquaculture and the evaluation of the water concerned is required.
