Background and objective Intestinal parasitic infections are a major public health concern, especially in low-income regions with poor sanitation. Our hospital caters to a large migrant population, but data on these infections in Portugal is limited. This study aimed to assess the prevalence and characteristics of intestinal parasitic infections in pediatric patients from epidemiological, clinical, and microbiological perspectives.

This paper proposes an image-based system designed to address four key tasks in an aquaculture tank with : estimating shrimp length and weight, counting shrimps, and evaluating feed pellet food attractiveness. A setup was designed, including a camera connected to a Raspberry Pi computer, to capture high-quality images around a feeding plate during feeding moments.

The aim of this pilot study was to determine the feasibility of biomarker acquisition in suspected acute stroke, using modern ultrasensitive immunoassay techniques, and explore their potential usefulness for stroke diagnosis and management.
Methods: In 62 patients with suspected acute stroke, blood samples were prospectively obtained upon arrival and prior to neuroimaging.
A new projector, Orthogonal-Distance Ray-tracer Varying-Full Width at Half Maximum (OD-RT-VF), was developed to model a shift-variant elliptical point-spread function (PSF) response to improve the image quality of a preclinical dual-rotation PET system. Approach: The OD-RT-VF projector models different FWHM values of the PSF in multiple directions, using half-height and half-width tube-of-response (ToR) values. The OD-RT-VF method's performance was evaluated against the original OD-RT method and a ToR model with constant response.

In Brazil, at least four lineages of influenza A virus circulate pig population: 2009 H1N1 flu pandemic (pH1N1), human-seasonal origin H3N2, H1N1 and H1N2 (huH1 lineages) viruses. Studies related to the occurrence of swine influenza A virus (SIAV) in Brazilian herds have been detecting an increase of occurrence of huH1 lineages. This study aimed to construct recombinant vaccines against the huH1N1 virus and test the immunogens in a murine model.
