We previously demonstrated that sphingosine-1-phosphate receptor 3 (S1PR3) in the medial prefrontal cortex (mPFC) prevents reductions in sociability normally caused by stress. S1PR3 is a ubiquitously expressed G-protein coupled receptor that regulates immune system function, although its regulation of other biological processes is not well understood. Pharmacological activators of S1PR3 might provide important insights for understanding the neural substrates underlying sociability.

The short-wave infrared range is highly significant for spectroscopic sensing and upcoming optical communication applications. Integrating active and passive photonic components is essential to achieve compact optical solutions. In this paper, we show, for the first time to our knowledge, a wavelength-selective detection system based on the heterogeneous integration of two grating-coupled InGaAs photodetectors operating at the 2µm wave band, with a wavelength selectivity provided by a dual-channel Mach-Zehnder interferometer fabricated using a silicon-on-insulator (SOI) wafer.

Interest in virus-based therapeutics for the treatment of genetic and oncolytic diseases has created a demand for high-yield, low-cost virus-manufacturing processes. However, traditional analytical methods of assessing infectious virus titer require multiple processing steps and manual counting, limiting sample throughput, and increasing human error. This bottleneck severely limits the development of new manufacturing unit operations to drive down costs.

People's emotional states are influenced not just by events occurring in the present but also by how events have unfolded in the past and how they are likely to unfold in the future. To what extent do young children understand the ways in which past events can affect current emotions even if they are no longer ongoing? In the current study, we explored children's ability to understand how others feel at the cessation of events-as events change from being present to being past. We asked 97 4- to 6-year-olds (40.

  • - Phenobarbital is a long-acting barbiturate used for treating alcohol withdrawal and epilepsy but can cause severe central nervous system depression in case of overdose.
  • - A case study of a 14-year-old girl showed that urinary alkalinization with sodium bicarbonate was used successfully for treating phenobarbital overdose, enhancing drug elimination.
  • - Despite the treatment increasing urinary excretion rates, there was no significant impact on the elimination half-life of the drug, indicating the need for further studies on the efficacy of urinary alkalinization in such cases.

Recent research suggests there may be differences in the social presentations of autistic males and females. Camouflaging is believed to account for some of these differences and executive function (EF) may support compensatory social behaviors. As few studies have explored the role of sex and everyday EF when evaluating specific social difficulties among autistic youth, the present study seeks to address this.

Major depressive disorder is one of the most prevalent psychiatric diseases, and up to 30-40% of patients remain symptomatic despite treatment. Novel therapies are sorely needed, and animal models may be used to elucidate fundamental neurobiological processes that contribute to human disease states. We conducted a systematic review of current preclinical approaches to investigating treatment resistance with the goal of describing a path forward for improving our understanding of treatment resistant depression.

Recent research in autism spectrum disorder (ASD) has suggested a higher prevalence of gender diversity in individuals diagnosed with ASD. Adolescence is a critical period for the consolidation of gender identity, yet the extent to which the experience of gender diversity is stable over adolescence and puberty in autistic youth is poorly understood. The aim of the study was to examine the consistency of gender diversity using the gender diversity screening questionnaire for self- and parent-report of youth (GDSQ-S, GDSQ-P) over a four-year longitudinal study of pubertal development in youth with ASD (N = 140, 36 assigned-female-at birth (AFAB)) and typical development (TD, N = 104, 58 assigned-male-at-birth [AMAB]) and their parents.

Inflammatory processes are increased by stress and contribute to the pathology of mood disorders. Stress is thought to primarily induce inflammation through peripheral and central noradrenergic neurotransmission. In healthy individuals, these pro-inflammatory effects are countered by glucocorticoid signaling, which is also activated by stress.
