Background & Aims: Circulating HBV RNAs have been proposed as a biomarker that reflects the transcriptional activity of covalently closed circular DNA (cccDNA) and may help to evaluate HBV treatment activity. Different research assays have been proposed and, although two PCR-based research use only investigational assays have been developed, the lack of standardized protocols represents an important limitation. Here we have designed and generated a stable clonal cell line producing an RNA-based standard for the calibration of PCR-based circulating HBV RNA assays.

Adaptation of reactive saccades (RS), made toward the sudden appearance of stimuli in our environment, is a plastic mechanism thought to occur at the motor level of saccade generation. As saccadic oculomotor commands integrate multisensory information in the parietal cortex and superior colliculus, adaptation of RS should occur not only toward visual but also tactile targets. In addition, saccadic adaptation in one modality (vision or touch) should transfer cross-modally.

October 2024

Department of Psychology & NeuroMI - Milan Center for Neuroscience, University of Milano-Bicocca, Milan, Italy; IRCCS Istituto Auxologico Italiano, Laboratory of Neuropsychology, Milan, Italy. Electronic address:

Humans are endowed with a motor system that resonates to speech sounds, but whether concurrent visual information from lip movements can improve speech perception at a motor level through multisensory integration mechanisms remains unknown. Therefore, the aim of the study was to explore behavioral and neurophysiological correlates of multisensory influences on motor resonance in speech perception. Motor-evoked potentials (MEPs), by single pulse transcranial magnetic stimulation (TMS) applied over the left lip muscle (orbicularis oris) representation in the primary motor cortex, were recorded in healthy participants during the presentation of syllables in unimodal (visual or auditory) or multisensory (audio-visual) congruent or incongruent conditions.

The NLRP3 inflammasome is a critical component of the innate immune response. NLRP3 activation is a tightly controlled process involving an initial priming to express NLRP3, pro-IL-1 β, and pro-IL-18, followed by an activation signal. The precise mechanism of activation is not fully understood due to the diverse range of activators, yet it effectively orchestrates the activation of caspase-1, which subsequently triggers the release of proinflammatory cytokines IL-1β and IL-18.

Laboratory Health Systemic Process (P2S), UR4129, University Claude Bernard Lyon 1, University of Lyon, 69100 Lyon, France.

In recent years, contrastive learning has been a highly favored method for self-supervised representation learning, which significantly improves the unsupervised training of deep image models. Self-supervised learning is a subset of unsupervised learning in which the learning process is supervised by creating pseudolabels from the data themselves. Using supervised final adjustments after unsupervised pretraining is one way to take the most valuable information from a vast collection of unlabeled data and teach from a small number of labeled instances.

Article Synopsis
  • GTPases from the Rab family play a crucial role in membrane trafficking, and issues with these proteins have been linked to various neurological disorders, particularly involving RAB11A variants causing developmental and epileptic encephalopathy.
  • The study examined 16 patients with RAB11A variants, mostly de novo heterozygous missense mutations, finding that these variants are associated with intellectual disability, developmental delays, and a range of other physical and neurological symptoms.
  • The research suggests that while epilepsy is less common and less severe in patients with binding site mutations, the RAB11A neurodevelopmental disorder can affect multiple body systems, including gait, muscle tone, brain structure, and even fat distribution.

A vast range of neurophysiological, neuropsychological and behavioural results in monkeys and humans have shown that the immediate surroundings of the body, also known as peripersonal space (PPS), are processed in a unique way. Three roles have been ascribed to PPS mechanisms: to react to threats, to avoid obstacles and to act on objects. However, in many circumstances, one does not wait for objects or agents to enter PPS to plan these behaviours.
