Leak and Scattering Assessment by Optically Stimulated Luminescence Dosimetry in a Helical Linear Accelerator

Radiation absorbed doses to organs outside the radiation therapy treatment beam can be significant and therefore of clinical interest. Two sets of out-of-beam measurements were performed measuring the leak dose and the scattered dose, at 5 points within the accelerator components (accelerator tube and co...

Efecto del ácido alfa lipoico sobre la peroxidación no enzimática en mitocondrias de corazón y cerebro de rata

Rev. med. vet. zoot; 68 (1), 2021
RESUMEN El ácido alfa lipoico (AAL) ha sido caracterizado como un antioxidante eficiente. Se ha propuesto como un agente terapéutico potencial en el tratamiento o prevención de diferentes alteraciones que pueden estar relacionadas con un desequilibrio del estado celular oxidoreductor.

Routine serum calcitonin measurement in thyroid nodules

Medicina (B.Aires); 79 (4), 2019
Existe mucha controversia sobre los beneficios de la medición de la calcitonina sérica (CT) durante la evaluación inicial de pacientes con nódulos tiroideos. El objetivo del estudio fue evaluar la identificación temprana del carcinoma medular de tiroides (CMT) a través de la medición rutinaria de ...

Investigation and environmental analysis of samples from outbreak of toxoplasmosis at research institution in Londrina, Paraná, Brazil, 2016

Abstract The objective of this study was to report an outbreak of human toxoplasmosis at a research institution in Londrina, Paraná, from December 2015 to February 2016. Blood samples from 26 symptomatic individuals were collected and the microparticle chemiluminescence immunoassay was performed to dete...

Assessing endocrine and immune parameters in human immunodeficiency virus-infected patients before and after the immune reconstitution inflammatory syndrome

ABSTRACT Objective The present study compares immune and endocrine parameters between HIV-infected patients who underwent the Immune Reconstitution Inflammatory Syndrome (IRIS-P) during antiretroviral therapy (ART) and HIV-patients who did not undergo the syndrome (non-IRIS-P). Materials and methods Bl...

Brazilian Bioluminescent Beetles: Reflections on Catching Glimpses of Light in the Atlantic Forest and Cerrado

An. acad. bras. ciênc; 90 (1,supl.1), 2018
ABSTRACT Bioluminescence - visible and cold light emission by living organisms - is a worldwide phenomenon, reported in terrestrial and marine environments since ancient times. Light emission from microorganisms, fungi, plants and animals may have arisen as an evolutionary response against oxygen toxicit...
