In this review paper, the role of fish as bio indicators is discussed. No other aquatic organism is suitable for the application of so many different methods which allow the evaluation of the severity of toxic impacts by determining the accumulation of toxicants in tissues, by using histological and haematological approaches or by detecting morphological anomalies. Due to its complex habitat requirements, the fish fauna is a crucial indicator of the ecological integrity of aquatic systems at different scales, from microhabitat to catchment.

O mercado mundial de flores e plantas ornamentais encontra-se em plena fase de expansão. A floricultura brasileira vem adquirindo notável desenvolvimento e se caracteriza como um dos mais promissores segmentos da horticultura intensiva no contexto do agronegócio nacional. Com o propósito de melhorar a qualidade das flores, o presente estudo teve como objetivo avaliar a influência da aplicação de diferentes concentrações de potássio e magnésio no desenvolvimento de plantas de crisântemo (Dendranthema grandiflora, Tzevelev.) cultivados em vasos.

This study aimed to analyze the health and environment aspects of the rural area that influence the quality of health in Teresina, Piaui, Brazil. This study was characterized as a reflective descriptive research of direct observation experience report. The participant observation study was conducted by health professionals who work in the primary health care of the Family Health Strategy within the community and carry out research studies in the rural area. The participant observation period was held in 2018, with various activities within the community.

Objective: This study aimed to know the conditioning factors of the transition process to the self-care of women diagnosed with HIV/AIDS. Method: This qualitative study was carried out from June to September 2015 with seven seropositive women, users of a specialized service in sexually transmitted diseases in the municipality of Imperatriz, Maranhão State, Brazil. For the data collection, an individual interview was used, and data analysis was performed by content analysis.

The objective of this work was to evaluate physiological changes related to deterioration of sweet potato roots cv. BRS Cuia during storage at room temperature, identifying the major problem during postharvest. It was determined weight loss, sprouts number, sprouts length, water potential, peroxidase and polyphenoloxidase enzymes activities, and fraction of soluble phenols. The evaluated variables showed increases, except for skin fraction of soluble phenols that decreased during storage.

The search for yeast with proteolytic activity that can be explored in technology and product innovation was the objective of this study to isolate and identify strains present in liquid whey and evaluate the proteolytic activity of isolates. From the isolated strains were selected for molecular identification, those with proteolytic activity. Verification of proteolytic activity was performed on milk agar and visualized by a translucent halo. Four strains belonging to two yeast species were identified as protease producers.

Drugs resistant microbes is a serious problem. As safe alternatives herbal medicines are discovered certain essential oils (non antibiotic substance) have shown fighting potential against drug resistant pathogens Antimicrobial activity of four different essential oils i.e. Tea tree, eucalyptus, menthol and camphor have been evaluated and were found susceptible to both gram positive i.e. Staphylococcus aureus and gram negative bacteria i.e. Escherichia coli. The antimicrobial susceptibility in each essential oils and commercial antibiotics i.e.

Industrialization and human activities makes intense impact on the environment by disposing industrial effluent containing heavy metals. Remedial procedures using biomaterials, such as, bacteria, algae, fungi, yeast, and agricultural waste biomass are regarded as a cost-effective technique for the treatment of high volume and low concentration of complex waste water containing heavy metals. In current research a microbial remedy is suggested to treat the chromium bearing effluent which includes application of bacterial culture i.e.

The Brazilian northeast presented an outbreak of children born with Microcephaly that in August 2015 through April 2016 (Brasília, 2015). Microcephaly is a congenital anomaly associated with brain damage. The Zika virus has, until now, been indicated as the main agent causing these anomalies. This work is a cross-sectional descriptive and analytical study of the retrospective type. As data source, the database of the Epidemiological Surveillance Rapid Response of the Ministry of Health was used based on the notifications made at the biggest maternity hospital in the state.

Azithromycin is the most active macrolide antibiotic. It is an azalide antibiotic. Azithromycin inhibits protein synthesis by binding reversibly to 50S ribosomal subunity. Azithromycin is bacteriastatic, but may be bactericidal, at high concentrations. This antibiotic is used for treating respiratory tract infections caused by common pathogens of community-acquired pneumoniae.
