community-acquired pneumonia and brucellosis are of the main agents causing mortality in the world. the most important limitations for the identification of these agents include their high resistance against environmental conditions, impossibility of rapid and on time diagnosis, low level of infective dose, and lack of existence of vaccine against many types of them. hence, on time action and d...

currently, different highly sensitive nucleic acid detection-based protocols used in medical diagnostic laboratories need specific working conditions, and if no optimization is performed, misleading results can be obtained. limitations of each protocol is different in obtaining an appropriate result. awareness of these limitations plays an important role in providing a reliable result for physi...

background and aims. the aim of the present study was to compare the effect of application of an image processing mode of a colorizer on the efficacy of the detection of interproximal carious lesions viewed in direct digital radiography. materials and methods. a total of 102 proximal surfaces of extracted human premolars on direct digital images were evaluated by three observers with and withou...

a sensitive monitoring of biological analytes, such as biomolecules (protein, lipid, dna and rna), and biological cells (blood cell, virus and bacteria), is essential to assess and avoid risks for human health. nanobiosensors, analytical devices that combine a biologically sensitive element with a nanostructured transducer, are being widely used for molecular detection of biomarkers associated ...

conclusions development of novel drugs and diagnostic tests has allowed us to better manage vl. although leishmaniasis is one of the oldest known parasitic infectious diseases, increasing prevalence of vl among specific populations, recent reports of disease reactivation and flare-up in clinically asymptomatic patients after the onset of immunosuppressive therapy, the risk of disease acquisitio...

context primary liver cancer is one of the most common and deadly malignant neoplasms worldwide. the incidence and mortality rates for hepatocellular carcinoma (hcc) are virtually identical, reflecting the poor overall survival of patients with this kind of tumor. effective therapies mostly achieved if the hcc diagnosis is made at early stages of the tumor. surveillance tests include serologic ...
