Automated pixel-based quantification of porcine circovirus 2 genome in formalin-fixed, paraffin-embedded tissues using hybridisation.

Introduction: Detection of porcine circovirus 2 (PCV2) in lymphoid tissues is essential for diagnostic and research purposes. hybridisation (ISH) enables the localisation of viral genomes in tissue sections but is traditionally assessed visually, which may introduce subjectivity.

Methods: This study developed an automated pixel classifier to quantify the PCV2 genome using RNAscope ISH technology.

Predictive encoding of auditory sequences in the human prefrontal cortex.

Humans extract regularities from the environment to form expectations that guide perception and optimize behavior. Although the prefrontal cortex (PFC) is central to this process, the relative contributions of orbitofrontal (OFC) and lateral PFC (LPFC) remain unclear. Here, we show that the brain tracks sound regularities in an auditory deviance detection task to predict when a target deviant will occur.

Enhanced Accuracy in Jump Power Estimation Using Photoelectric Cell System and GRS80 Location-Specific Gravitational Acceleration.

Power is essential in sports and is typically calculated using a standard gravity value of = 9.81 m·s. However, this value varies according to altitude and geographical latitude.

Stereoelectroencephalography at Sainte-Anne Hospital, Paris, France.

Stereoelectroencephalography (SEEG), which combines the exploration of identified intracerebral structures using depth electrodes and provides direct recording of local field potentials from multiple brain sites, was designed and developed in the 1950s by Jean Talairach and Jean Bancaud, in Sainte-Anne Hospital, Paris. For patients with focal drug-resistant epilepsy, when the non-invasive phase is insufficiently concordant or when relationships between the epileptogenic network and eloquent areas remain to be defined, the main purpose of SEEG is the optimal electrode implantation based on a main hypothesis and questions formulated during the non-invasive phase. Following an initial historical overview, the different steps of this non-invasive phase are described.

How can emotion and familiarity improve own-name oddball paradigms?

The own-name paradigm is used to assess the depth of consciousness disorders in patients in intensive care units. This auditory oddball paradigm elicits a positive event-related potential at 300 ms (named P300) after the presentation of a deviant auditory stimulus, here the subject's own-name. This P300 likely reflects the neural processing of the novel stimulus, which can trigger a behavioral response.
