Otimização de método para analise de tebutiurom, diurom e seus produtos de degradação em água superficial

In 2001, it was estimated that pesticide used worldwide exceeded 2.27 billion kilograms, over 35%, of which, were herbicides. Brazil is considered one of the leaders in the production of sugarcane and mainly ethanol as fuel. The monoculture of sugarcane requires the usage of a range of pesticides, among these, the herbicides diuron and tebuthiuron. The degradation products most studied (DCA and DCPU) are diuron's, especially for toxicological characteristics of this herbicide that is identified as carcinogen and suspected to be endocrine disruptor in mammals. After optimization of the chromatographic separation using HPLC-UV, the analytical curve was constructed in solvent and subsequently in the matrix (surface water). The extraction method contains the usage of SPE (solid phase extraction) (Strata-X, 200 mg/6 mL), applicating 1L of sample and elution with 5 mL of acetonitrile / methanol (50:50, v/v). Analysis by HPLC/UV was performed in gradient mode, acetonitrile/water (70/30-74/26 by 1 min, 74/26 - 78/22 till 3.2 min, returning to initial conditions and remaining this way until 10 min), 018 column (Phenomenex, 4.6 mm diameter, 250 mm long and 5pm particle size) and detection at 254 nm. Tests F and t were performed to verify the presence of the matrix effect. There was matrix effect to all analytes, ranging from -33% (DCA) and 38% (tebuthiuron). Thereby the method was optimized and validated for analysis of diuron, tebuthiuron, and DCPU DCA in surface water using HPLC/UV. The data obtained show that in order to assure the analytical reliability desired the use of the analytical curves in the matrix for the quantification of these analytes in water is required.

Elaboração de produto cárneo de tilápia com antioxidantes visando sua utilização como recheio ou acompanhamento de refeição

The aim of this study is to evaluate the effi ciency of oregano, sage, moringa and rosemary as natural antioxidants and propyl gallate as artifi cial antioxidant used in “stuffed food” made with CMS of tilapia (minced fi sh) and stored frozen for 120 days. Protein, fat, moisture and ashes determination, microbiological analysis and sensory evaluations were conducted in the beginning and the end of storage period. TBARS, BNVT, pH and psychrotrophic microorganism count were determined periodically. The antioxidants interfered in pH (6.17 and 6.55) and TBARS values during 120 days under freezing (-18o C). The lowest TBA values were found for oregano (0.158 mg de MDA. kg-1) and sage (0.186 mg de MDA.kg-1). The stuffed food made with CMS of tilapia, without antioxidant, had the most oxidation, and sage and moringa were not good source of antioxidant. BNVT values (11.41 – 12.35 mgN.100g-1) were not altered. The lowest pH value was found for the product with sage (6.20), but similar to the moringa and propyl gallate, while oregano and rosemary showed the highest values (6.63 and 6.29), at 5 days of storage. Microbiological analyses were in accordance with Brazilian legislation. Sensory evaluation indicated that the panelists preferred the formulations made with oregano and propyl gallate. The results showed that it is feasible to elaborate stuffed food made with CMS of tilapia as an alternative for the fi shery´s consumption, and sage was the most effi cient natural antioxidant among those tested in this study.

Boas práticas de laboratório e biossegurança: prevenção dos riscos ergonômicos

El control de los riesgos ergonómicos es parte del paquete de medidas de Buenas Prácticas de Laboratorio y Bioseguridad. De este modo, la mala postura, la iluminación o ventilación inadecuadas , prolongada jornada de trabajo, la monotonía y la actividad repetitiva, intensa rutina, el control de la productividad , el estrés y el trabajo por la noche son factores a los riesgos ergonómicos. Como se relacionan a los elementos físicos y de organización también pueden interferir con la comodidad y la salud del personal de laboratorio. Riesgos ergonómicos no sólo pueden generar trastornos psicológicos y fisiológicos que causan graves daños a la salud, sino también comprometer la productividad del laboratorio y reducir el equipo de seguridad , ya que producen cambios en el cuerpo y el estado emocional, tales como trastornos o lesiones relacionadas con el cansancio físico producido por el trabajo repetitivo, dolor muscular, alteraciones del sueño, diabetes, trastornos de los nervios , la taquicardia , las enfermedades del aparato digestivo (gastritis y úlcera ), tensión, ansiedad, problemas de espalda y la hipertensión. En este trabajo se propone una secuencia de actividad laboral (gimnasia) en el intervalo de tiempo pequeño, respetando las instalaciones y el espacio físico disponible en el ambiente del trabajo, como una estrategia para mejorar la calidad de vida laboral, para aumentar la productividad, mejorar la disposición a trabajar y para aumentar el conocimiento del cuerpo y de la interacción social.

Validation of analytical methodology for quantification of cefazolin sodium by liquid chromatography

A reversed-phase high performance liquid chromatography method was validated for the determination of cefazolin sodium in lyophilized powder for solution for injection to be applied for quality control in pharmaceutical industry. The liquid chromatography method was conducted on a Zorbax Eclipse Plus C18 column (250 x 4.6 mm, 5 μm), maintained at room temperature. The mobile phase consisted of purified water: acetonitrile (60: 40 v/v), adjusted to pH 8 with triethylamine. The flow rate was of 0.5 mL min-1 and effluents were monitored at 270 nm. The retention time for cefazolin sodium was 3.6 min. The method proved to be linear (r2 =0.9999) over the concentration range of 30-80 µg mL-1. The selectivity of the method was proven through degradation studies. The method demonstrated satisfactory results for precision, accuracy, limits of detection and quantitation. The robustness of this method was evaluated using the Plackett–Burman fractional factorial experimental design with a matrix of 15 experiments and the statistical treatment proposed by Youden and Steiner. Finally, the proposed method could be also an advantageous option for the analysis of cefazolin sodium, contributing to improve the quality control and to assure the therapeutic efficacy
