Early life seizures and olfactory communication in rats.

Objective: Early life seizures (ELS) are commonly associated with autism spectrum disorder (ASD); however, the exact role of ELS in the pathology is unknown. Prior studies have demonstrated social deficits, a core feature of ASD, following ELS; consequently, alterations in sensory modalities may contribute to the overall social deficits. Considering the speculated contribution of sensory deficit to social communication, we examined the developmental consequences of early postnatal kainic acid (KA)-induced seizures on olfactory preference and neural markers in the olfactory bulb in both male and female Sprague Dawley rats.

Getting a handle on rat familiarization: The impact of handling protocols on classic tests of stress in .

Experimenter familiarization with laboratory rodents through handling prior to experimentation is an important practice in neurobehavioral research and is implicated in stress, study variability, and replicability. Unfortunately, different handling protocols have not been thoroughly examined. Determining optimal experimenter familiarization protocols is expected to reduce animal stress and thus improve welfare and data consistency.

Mindfulness Meditation Programs Informed by Transgender Youth.

Objectives: This study explores the openness of transgender and gender diverse youth and young adults (TGDY) to mindfulness meditation programs in order to create culturally informed interventions to benefit this population.

Method: Two focus groups were conducted with a total of ten TGDY ages 14-24 years old at a transgender youth health center in a large metropolitan city in the USA. A 10-min guided mindfulness meditation was included for participants to experience and voice reactions to.

Data collection from crystals grown in microfluidic droplets.

Protein crystals grown in microfluidic droplets have been shown to be an effective and robust platform for storage, transport and serial crystallography data collection with a minimal impact on diffraction quality. Single macromolecular microcrystals grown in nanolitre-sized droplets allow the very efficient use of protein samples and can produce large quantities of high-quality samples for data collection. However, there are challenges not only in growing crystals in microfluidic droplets, but also in delivering the droplets into X-ray beams, including the physical arrangement, beamline and timing constraints and ease of use.
