Autoimmune Thyroid Disease: An Unusual Cause or Confounder of Vertigo.

Over the last decade, the published literature investigating the association between thyroid function and recurrent or persistent vertigo has become more robust. We present an interesting case of persistent vertigo in a healthy 31-year-old active duty Navy pilot who was restricted from operating single-pilot rotary aircraft because of the severity of her symptoms. During her work-up, she was newly diagnosed with autoimmune thyroid disease and started on thyroid hormone supplementation.

MNase-Seq Analysis for Identifying Stress-Altered Nucleosome Occupancy in Plants.

Nucleosome occupancy plays an important role in chromatin compaction, affecting biological processes by hampering the binding of cis-acting elements such as transcription factors, RNA polymerase machinery, and coregulatory. Accessible regions allow for cis-acting elements to bind DNA and regulate transcription. Here, we detail our protocol to profile nucleosome occupancy and chromatin structure dynamics under drought stress at the genome-wide scale using micrococcal nuclease (MNase) digestion.

Bicolour, large area, inkjet-printed metal halide perovskite light emitting diodes.

We demonstrate a bicoloured metal halide perovskite (MHP) light emitting diode (LED) fabricated in two sequential inkjet printing steps. By adjusting the printing parameters, we selectively and deliberately redissolve and recrystallize the first printed emissive layer to add a pattern emitting in a different color. The red light emitting features (on a green light emitting background) have a minimum size of 100 μm and originate from iodide-rich domains in a phase-segregated, mixed MHP.

Control of contextual memory through interneuronal α5-GABA receptors.

γ-Aminobutyric acid type A receptors that incorporate α5 subunits (α5-GABARs) are highly enriched in the hippocampus and are strongly implicated in control of learning and memory. Receptors located on pyramidal neuron dendrites have long been considered responsible, but here we report that mice in which α5-GABARs have been eliminated from pyramidal neurons (α5-pyr-KO) continue to form strong spatial engrams and that they remain as sensitive as their pseudo-wild-type (p-WT) littermates to etomidate-induced suppression of place cells and spatial engrams. By contrast, mice with selective knockout in interneurons (α5-i-KO) no longer exhibit etomidate-induced suppression of place cells.
