The importance of assessing water quality for human consumption is based on the fact that it is one of the main vehicles for infectious diseases. The objective of this research was to evaluate the quality of water for human consumption through the microbiological characterization of water from open and closed wells of Palmares, Araguatins (TO) settlement. The collections were carried out during the period from 16 to 20 October in two settlement wells. The results obtained were compared with the Ministry of Health Resolution No. 2,914 of 12/12/2011.

Conventional farming system may cause physical and chemical soil degradation. Plant residue retention can be used to improve soil aggregation and chemical properties. However, the effectiveness of plant residue retention in conventional farming (CF) system remains unclear. Therefore, we studied the influence of plant residue retention on the water-stable aggregates, mean weight diameter of water-stable aggregates, bulk density and soil chemical properties.

Studies in several countries have warned on the contamination of fish by heavy metals, especially Pangasius hypophthalmus, farmed in the Mekong river, Vietnam, one of the most polluted rivers in the world, and exported to all countries. Current paper quantifies the concentrations of heavy metals in samples of frozen panga fillets. Risk to human health associated to the consumption of fillets was calculated according to heavy metal levels.

Introduction: Hepatitis is an important public health problem in Brazil, with different regional distributions. Objective: This study analyzed the epidemiological profile of viral hepatitis in the State of Maranhão between 2008 and 2017. Method: An observational, quantitative, longitudinal and retrospective study of the cases reported in SINAN was performed. 6,876 confirmed cases were registered, predominantly in the urban area and in the capital city of São Luís.

This work presents information about the digestive tract contents of the green turtles (Chelonia mydas) on the southern coast of Pernambuco, Northeast Brazil. Between November 2016 and October 2018, the gastrointestinal tract contents were collected from 44 stranded dead individuals. The diet consisted mainly of red algae (65.90%), especially the species Pterocladiella beachiae, Gelidium lineare (52.72%) and Gelidiella acerosa (47.72%).

Globally, breast cancer incidence is on the rise, especially in developing countries and it is the most diagnosed cancer among women in Kenya. For the prevention and treatment, knowledge on early detection and risk factors is very important, however this has not been assessed among women of reproductive age attending Longisa County Referral Hospital Bomet County, Kenya. The study adopted a cross-sectional hospital based design to assess the knowledge on early detection and risk factors to breast cancer among 194 women of reproductive age (15-49 years).

Diseases affecting the female reproductive system are becoming more prevalent worldwide, among which are the bacterial vaginosis caused by the bacterium Gardnerella vaginalis and cervical cancer caused by the Human Papilloma Virus (HPV). may corroborate for significant pathological consequences.

O câncer de pele é causado por exposição intensa aos raios solares, e pelo fato do Brasil ser um país de clima tropical, existem fatores que auxiliam na exposição solar cotidiana da população (trabalho ao ar livre e a beleza associado ao bronzeamento). A família Euphorbiaceae possui metabólitos secundários, como, os taninos e flavanóides, considerados antioxidantes e associados a Fator de Proteção Solar. Nessa família, destaca-se Cnidoscolus quercifoliusPohl(Favela), considerada resistente à seca e a forte irradiação solar.

Objetivo: Avaliar a citotoxicidade do extrato hexano de Psidium guineense em células sanguíneas humanas (eritrócitos) para que possa se determinar a toxicidade teórica desta planta. Métodos: Para a realização dos estudos de atividade citotóxica foram prepradas suspensões sanguíneas com sangue humano A, B e O, que foram misturadas a diferentes concetrações do extrato hexânico por 60 minutos e a hemólise quantificada por espectrofotometria em comprimento de onda de 540 nm. Resultados: O extrato hexano de P.

The objective of the present study was to assess the selectivity of five herbicides and their potential pre-emergent control over weeds in the forage palm crops. A completely randomized design was used to evaluate selectivity in triple factorial (2 x 5 x 7) considering varieties, herbicides and seasons assessed, respectively. In turn, the experiment to evaluate weed control was conducted with a completely randomized design with five treatments and one control with eight replications, yielding a total of 48 units.
