AI Article Synopsis

  • Neonatal status epilepticus (SE) negatively impacts the prefrontal cortex and thalamus, areas important for social interactions.
  • An experiment using the "intruder-resident" paradigm on 9-day-old Wistar rats showed that neonatal SE leads to social deficits in male rats and decreased movement in both genders, while also increasing self-grooming behavior in females.
  • Further research is needed to determine if these social behavior impairments persist throughout the rats' lives.

Article Abstract

Neonatal status epilepticus (SE) disrupts prefrontal cortex and thalamus, brain regions related to social play. Juvenile play was evaluated using the "intruder-resident" paradigm following SE in 9-day-old Wistar pups of both genders. Quite interestingly, we demonstrated for the first time that neonatal SE produces social impairment in male rats, reduces locomotor activity in both genders and enhances self-grooming in female. Additional studies are necessary to clarify if these effects can impair social behavior across the life span.

Review of Applications of Microneedling in Melasma.

J Cosmet Dermatol

January 2025

Department of Dermatology, Peking University Shenzhen Hospital, Shenzhen, China.

Background: Melasma, a common skin pigmentation disease, can negatively impact patients' mental health, social interactions, and physical appearance. Although we now have several treatments accessible, such as medicines, chemical peels, and phototherapy, which can help ease symptoms to some extent, the requirement for a long-term effective and safe treatment for patients is far from met. In the face of this problem, microneedling, as an innovative treatment, provides a new avenue for treating melasma.

Background: Healthcare professionals play an important role in successfully implementing digital interventions in routine mental healthcare settings. While a larger body of research has focused on the experiences of mental healthcare professionals with the combination of digital interventions and face-to-face outpatient treatment, comparatively little is known about their experiences with digital interventions combined with inpatient treatment. This is especially true for acute psychiatric inpatient care, where studies on the implementation of digital interventions are more rare.

Background: Understanding the neural basis of behavior requires insight into how different brain systems coordinate with each other. Existing connectomes for various species have highlighted brain systems essential to various aspects of behavior, yet their application to complex learned behaviors remains limited. Research on vocal learning in songbirds has extensively focused on the vocal control network, though recent work implicates a variety of circuits in contributing to important aspects of vocal behavior.

Strong social bonds in gregarious adult animals have been associated with lower levels of glucocorticoids. However, similar research is lacking for juvenile primates. We examined relationships between social bonds and mean concentrations of fecal glucocorticoid metabolites (fGCMs) in 44 free-ranging juvenile rhesus macaques (Macaca mulatta) on Cayo Santiago, Puerto Rico.
