We are analyzed forty samples of raw milk commercialized at the Callao Market between January and March 2009 using presumptive method for β-lactamics and tetracycline antibiotic residues from IDEX laboratories, to comply with the limits of sensitivity of residues of the FDA. We found 40% of samples tested positive for β-lactamic residues in raw milk. There were no positive outcame to analyze tetracyclines. The results suggest that we should establish policies for legislation, regulation and training and that the NTP 202.001.2003 should be reviewed. The results suggested that should be established policies for legislation, regulation and training, and the NTP 202. 00102003 should be reviewed.

This research was conducted using the Polymerase Chain Reaction (PCR) to detect heat-labile toxin of Escherichia coli in 24 fresh cheeses manufactured with cow and goat milk. The advantages of the PCR technique, over other analysis techniques, are reliability and rapidity to obtain the results. 24 samples of cheese (from cow and goat milk) were studied obtaining 58.33% of positive cases; 72.72% were positive with fresh goat milk and 46.16% of cow milk. Moreover, the X2 analysis showed, with 99% reliability, that the positive and negative results of the samples tested did not depend on the type of cheese used but did so on other factors, such as good manufacturing practices and standardization of the procedure.

En la presente investigación se detectó presencia de toxina termolábil de Escherichia coli, mediante la técnica de la reacción en cadena de la polimerasa (PCR), en 24 muestras de quesos frescos manufacturados con leche de cabra y vaca. Se optó por el método de PCR por las ventajas que ofrece respecto a otros métodos de análisis, en cuanto a confiabilidad y rapidez de obtención de los resultados. De 24 muestras de queso (cabra y vaca) analizadas, el 58,33% fueron positivas; 72,72% de las muestras de queso fresco de cabra y 46,16% de las muestras de quesos de leche de vaca. Por. otra parte, el análisis de X2 demostró, con 99% de confiabilidad, que los resultados positivos y negativos de las muestras analizadas no dependen del tipo de queso sino de otros factores, como las buenas prácticas de manufactura y la estandarización del procedimiento.

This technique has only been used for the extraction of fish oil, it consisted in the alkaline hydrolysis of glycerides using a rate of 50% KOH for saponification and methylene chloride to extract the unsaponificable part. After saponification and the formation of the sal!, it is acidified to obtain free fatty acids, using acetic acid al temperatures lowers !han -20 ºC. Following the extraction the organic phase containing free fatty acids are dissolved in acetone and temperature used -20ºC ( 20 celsius) precipitates the saturated fatty acids and they are separated by filtration. lt is purified using magnesium salts dissolved in acetone, which means that the unsaturated fatty acids are more soluble. This sample was tested with quality controls like the lodine index, giving much higher values (196) from the once we started (192). lt was also analyze with a GC IS05509-2000 and ISO 5508-1...

El objetivo del trabajo fue evaluar el efecto de la inulina como prebiótico natural sobre los parámetros productivos de cuyes en crecimiento. Se realizó en el galpón de cuyes de la EP de Ingeniería Agroindustrial de la UNMSM con sede en San Juan de Lurigancho – Lima. Se emplearon 5 tratamientos: T1: Control (con APC), T2: Sin inulina y sin APC, T3: 150 ppm de inulina, T4: 300 ppm de inulina y T5: 600 ppm de inulina; en un periodo de 5 semanas. Se emplearon 40 cuyes machos genotipo Cieneguilla, de 28 +/- 2 días de edad, adquiridos de una granja de cuyes de Manchay. Se empleó un Diseño Completamente al Azar. Los animales fueron distribuidos en 5 tratamientos y 4 repeticiones, cada repetición representada por 2 cuyes alojados en una poza, previamente identificados. Los cuyes que recibieron el tratamiento con 150 ppm de inulina presentaron el mayor consumo de alimento con 1154 g, ...

Arequipa, Peru’s second economic center hosting c. 1,110,000 inhabitants, is the largest South American city exposed to a large variety of natural hazards. At least 200,000 live in areas likely to be affected by hazards from El Misti volcano, located 17 km to the NE. A multidisciplinary project aims to address the impacts of tephra fall and frequent mass flows on the vulnerable building stock and roofs along two ravines that cross the city, enabling decision-makers to undertake retrofitting projects and improve urban risk planning. Two recent eruptions, that is, the 1440–1470 CE Vulcanian event and c. 2070 years BP Plinian eruption, were chosen as references for probable scenarios of potential tephra fall impacts from El Misti on the building roofs. Tephra fall impacts on the city depend on the eruptive style, column height, and patterns of wind directions and velocities over south P...

We work with Tagetes etiptica "ch incho" of Huancayo y Catathea tutea "bijao" of Pucallpa. Oil obtained of "chincho" contained doubles bonds. "bijao· doesn't contain oil. The diclhorometane extrae! of "chincho" contains yelllow crystals TE1 and white powder TE2. The chromatographic analysis shows polar metabolites in both samples. Using phitochemist analysis we found, esteroidal triterpenoids, flavonoids, tanines, quinonas, antocianinas and alcaloides in te "chincho", In tehe "bijao" sample we found saponinas, gálic tanines, flavonoids, cumarines and alkaloids. In both sample we found calcium, phosphates, magnesium, iron, cinc, sulphur and potassium.

The goal of this research work is the design of a cleaner process for the production of fuel ethanol sweet potato. Applying the principles of conceptual design, Pinch analysis and the use of simulators chem cad and pinch cad, it is determined that the process with molecular sieves is the most effective to get ethanol from 99.5% purity with a power demand of 1400 Kj/kg of ethanol. We conclude that these results impacting positively on the economy of Peru by establishing a path of sustainable development both technically, economically, socially and environmentally.

Introduction: Stage III non-small-cell lung cancer (NSCLC) management is challenging given the heterogeneous nature of the disease. The LATAM subset of the real-world, global KINDLE study reported the treatment patterns and clinical outcomes for LATAM from the pre-immuno-oncology era. Methods: The study was conducted in seven countries (Argentina, Chile, Colombia, Dominican Republic, Mexico, Peru and Uruguay) in stage III NSCLC (American Joint Committee on Cancer, 7th edition) diagnosed between January 2013 and December 2017. Retrospective data from patients' medical records (index date to the end of follow-up) were collected. Summary statistics, Kaplan–Meier survival estimates and a two-sided 95% confidence interval (CI) were provided. Cox proportional hazard model was used for univariate and multi-variate analyses. Results: A total of 231 patients was enrolled, the median age was 65....

We worked with the cladode, gel and pulp of the fruit: red, purple and white of Opuntia ficus-indica “tuna” in the region of Ayacucho Wari Department, Huamanga province in order to determine the presence of minerals, metabolites secondary antioxidant capacity and consider a functional food. The phytochemical screening according to the method of Cain - Bohmann determined catechic the presence of tannins, steroidal saponins, flavonoids, coumarins, and alkaloids. The total fiber content was found in the range of 0,42 to 0,68%, fat 0,01 to 0,02% protein and 0,39 to 0,57%. For analysis of nutrients as found AOAC magnesium, calcium, zinc and phosphorus, potassium and iron traces. Due to the presence of these nutrients to the tuna it can be considered as a functional food. Jams pulp obtained tunas studied were evaluated according to standard NTS MINSA No. 071 / DIGESA V.01, giving as a pass...
