The matrinxã fish is suitable for Amazonian aquaculture, exhibiting positive characteristics such as good growth and feed conversion ratio. However, it is a very active fish and must be anesthetized for handling. The present study evaluated the use of Ocimum gratissimum essential oil (EO) as anesthetic for juvenile matrinxãs. A first experiment assessed the induction time to anesthesia of 7 concentrations (20, 30, 40, 50, 60, 70 and 80 mg L-1 of O. gratissimum (EO). A second experiment investigated the physiological response to the anesthetic through analysis of tissue and blood parameters collected 0h (T0) and 24h after (T24) the experimental protocols that were applied to 4 groups: control, handling without O. gratissimum (EO) and handling with two EO levels. In the first experiment, fish were anesthetized within 10 min in the lowest EO concentration (20 mg L-1), and recovered within 2 min. As concentrations increased times to induction to anesthesia decreased from 10 min to 1 min (approximately). In the second experiment, plasma lactate, glucose and ammonia increased in the treatments involving handling and EO concentrations. After 24h, fish had recovered from the experimental procedures, and no mortality was observed in the next 30 days. Ocimum gratissimum was shown to be a suitable anesthetic for matrinxãs, and causes minimum stress to fish in the concentrations and exposure time applied. © 2016, Eduem - Editora da Universidade Estadual de Maringa.

The food security is a key concern, since there is the need of food intake; with acceptable standard of quality, that does not imply a health risk. This paper assesses the environmental risk in a port area located in the south of Manaus-AM, with 150 m long, between the streams of Educandos and São Raimundo, near major shopping sites; and the environmental sanitary condition of the fish during its marketing, packaging and disposal. In the analysis process were considered sanitary conditions of the environment and the food handler. The method used was the Failure Analysis, Modes and Effects (FMEA). The results demonstrate that the application of FMEA for calculating risk provides the identification of critical points, the different intensities of occurrence and it is enabled to indicate possible improvements. Regarding the place of analysis, this is in a degree of risk ranging from moderate to high. The factors that may cause harmful vectors of public health associated with improper handling of fish, the local infrastructure and food hygiene occur in 64% of cases. In addition, the generation of wastewater, solid waste and without quality control was associated with 36% of cases. Despite the unfavorable context, this kind of trade is a local vocation, and must go through a review process of the government to search for an environmental quality accompanied by the food safety of fish sold. © 2015 R.

The objective of this work was to evaluate the effect of the inclusion of cowpea (Vigna unguiculata) in diets on the performance of juvenile tambaqui (Colossoma macropomum). The experiment was carried out in a completely randomized design with three replicates of 20 juvenile tambaqui (10 g), allocated in 310-L water tanks. The fish were fed for 60 days with isonitrogenous and isoenergetic diets, with six inclusion levels of cowpea: 0, 5, 10, 15, 20, and 25%. Body and productive performance relations were determined. There was no significant difference between treatments. Juvenile tambaqui can be fed with the inclusion of up to 25% cowpea in the diet.

Introduction: The cochlear implant is a device that is intended to substitute for the function of cochlear hair cells, electrically stimulate auditory nerve fibers, and contribute to the perception of speech sounds. However, the surgical procedure alone is not enough for the user to achieve favorable results in habilitation/rehabilitation. Objective: To characterize the patients from Manaus who have received cochlear implants based on the criteria for surgery. Methods: We conducted a retrospective cross-sectional study of 15 cases and recorded etiological aspects of deafness, age, gender, duration of implant use, use of hearing aids, and participation in individual therapy. Data were recorded in a protocol designed specifically for this purpose. All patients were natives of Manaus. Results: The leading etiological aspect was ototoxicity associated with prematurity in newborns undergoing treatment in the neonatal intensive care unit. The age at surgery is carefully observed in the evaluation of implant centers, as well as if the candidate is pre-or post-lingual. In this study, 73% of patients were pre-lingual and did not benefit from hearing aids. As to the degree and type of hearing loss, 93% had audiological reports indicating profound bilateral sensorineural hearing loss and 7% had severe bilateral sensorineural hearing loss. This latter finding confirmed one of the basic principles of implant placement. Conclusion: This study allowed us to verify that there are reduced number of cochlear implant recipients in Manaus, but they have met the criteria required by implant centers located in other states of Brazil.

Text highlighting is often used to emphasize parts of a document for some reason. As highlighting is a personal choice of the reader, it can be seen as physically "damaging" the original document. A recent paper shows how to remove felt-pen highlighting in monochromatic documents with a white paper background. This paper generalizes that result to filter out highlighting in monochromatic documents with non-white background due to paper natural aging. © 2013 Springer-Verlag.
