This paper aims to provide information on and analyze recent contributions about the Influence of heat treatment on dairy products. Changes were found in the milk components affected by the heat treatment as in proteins (emulsion properties, α-lactalbumin and β-lactoglobulin), lactose (lactulose formation), enzymes (activity of lactoperoxidase, Υ-glutamyl transferase and alkaline phosphatase), vitamins (vitamin D stability), fat (particle size and stability of linoleic acid), on bacteria (aerobic and bacillus amyloliquefaciens) on microbial agents (tetracycline and sulfonamide), and other variables such as aromatic hydrocarbons (PAHs) and growth factor (TGF-β2); furthermore changes in the physical properties of yogurt (syneresis, roughness, grain number and perimeter) and cheese (proteolysis, lipolysis and sensory characteristics) also affected by the heat treatment is found.

En este trabajo de investigación que tiene como título “Herramientas geomáticas para el mantenimiento vial en la urb. Monterrico Norte - distrito San Borja - departamento y provincia de Lima”, se realizó con el objetivo principal de Aplicar las herramientas geomáticas para sistematizar el índice de condición de pavimento e identificar la secuencia de actividades para obtener el mantenimiento vial en la zona delimitada. En la presente investigación se realizó una inspección visual y de medición en el lugar de estudio, encontrándose distintas fallas en el pavimento rígido (grieta de esquina, losa dividida, grieta lineal y otras). Por tanto, se calculó el índice de condición de pavimento (PCI) e identifico los tipos de actividades en el mantenimiento vial, mediante la herramienta Network Analyst. De este modo se ha logrado recopilar una base de datos, mediante la sistema...

The study was conducted in the district of Pachacamac, a destination recognized for its significance in offering a variety of dishes from the three regions of the national territory. The establishment that served as the pilot to generate the Methodology for designing a Gastronomic Route was selected through a series of criteria that evaluated different aspects of the restaurant, supported by López et al. (2022). To identify the characteristics of the visitor, an 11-question closed questionnaire in Office Forms was used, validated by three specialists, administered in 4 sessions each weekend, and analyzed with IBM SPSS Statistics. The survey was conducted in the Plaza de Armas of the District of Pachacamac during the gastronomic fairs held every weekend. The sample included 383 people and focused on demographic, psychographic, and behavioral aspects. The results revealed that proposing a...

We report the results of mass treatment, with respect to Enterobius vermicularis and Ascaris lumbricoides of 1,627 people in a Lima orphanage, with a single oral dose of pyrantel pamoate.  A sample of 417 children was chosen at randon to provide confidence limits of over 95%; th GRAHAM scotch tape technique, adequate to detection of Enterobius ova, was performed twice botton before and after treatment in 386 of the selected children; 369 children provided fecal samples which were studied by the following techniques: Direct motile larvae and protozoa), and Rapid Sedimentation (for dense ova, such as Fasciola hepatica); other children failed to provide either the pre-post-treatment samples. E. vermicularis ova were found in 249 (64.5%) of the 386 children. A. lumbricoides ova were found in 22 of the 369 children. ´Pyrantel pamoate, as a suspension, and at a dose of 10mg per kg body w...

OBJETIVO. El objetivo de este estudio fue medir la eficacia diagnóstica de la técnica de sedimentación espontánea en tubo descrita por Tello (TSET), en comparación con el examen directo y otras técnicas de concentración, cuando se usa para determinar la prevalencia de enteroparasitosis en trabajos de campo y laboratorio en zonas rurales de la sierra y selvas peruanas. METODOS. Se realizó un estudio prospectivo (2000 – 2004) donde se incluyeron 1 802 muestras de heces de diversas zonas del Perú: Iquitos (N=74), Puno (N=399), Junín (N=1241), Lima (N=88). RESULTADOS. La TSET presentó mayor sensibilidad para la detección de helmintos y protozoarios en comparación con las otras técnicas convencionales empleadas simultáneamente (P<0.000). Aunque no se debe prescindir de otras técnicas coprológicas, como Baermann para diagnóstico de Strongyloides stercoralis y l...

La estrongiloidiosis es una enfermedad parasitaria intestinal causada por S. stercoralis, un nemátode geohelmíntico altamente prevalente en zonas tropicales y subtropicales. El tratamiento de elección actual es ivermectina, y como segunda alternativa el tiabendazol - disponible en algunas instituciones de salud en el Perú. Nuestro objetivo fue evaluar la eficacia y tolerabilidad del tiabendazol (25 mg/kg/día) repartido dos veces al día –después de las comidas- por 3 días, en individuos con infección crónica por S. stercoralis. El estudio fue llevado a cabo en el Hospital de La Merced, provincia de Chanchamayo, Perú (zona endémica); en un periodo de 90 días. El estudio incluyó a 32 individuos (22 mujeres - 10 hombres; media de edad ± DS = 9.34 ± 8.11 años) con diagnóstico parasitológico de S. stercoralis. Los exámenes de seguimiento fueron recuentos de eosinófilos, ...
