We performed descending thoracic aortic repair via posterolateral thoracotomy using retrograde cerebral perfusion with direct cannulation into the left internal jugular vein. No postoperative neurological dysfunction was observed. This patient was discharged without any adverse events.

An intra-brainstem circuitry for pain-induced inhibition of itch.

Pain and itch are unpleasant and distinct sensations that give rise to behaviors such as reflexive withdrawal and scratching in humans and mice. Interestingly, it has been observed that pain modulate itch through the neural circuits housed in the brain and spinal cord. However, we are yet to fully understand the identities of, and mechanisms by which specific neural circuits mediate pain-induced modulation of itch.

Chronic kidney disease (CKD) is a conceivable new risk factor for cognitive disorder and dementia. Uremic toxicity, oxidative stress, and peripheral-central inflammation have been considered important mediators of CKD-induced nervous disorders. Nitric oxide (NO) is a retrograde neurotransmitter in synapses, and has vital roles in intracellular signaling in neurons.

The lateral septum (LS) demonstrates activation in response to pup exposure in mothers, and its lesions eliminate maternal behaviors suggesting it is part of the maternal brain circuitry. This study shows that the density of pup-activated neurons in the ventral subdivision of the LS (LSv) is nearly equivalent to that in the medial preoptic area (MPOA), the major regulatory site of maternal behavior in rat dams. However, when somatosensory inputs including suckling were not allowed, pup-activation was markedly reduced in the LSv.

BK channels can control neuronal function, but their functional relevance in activity-dependent changes of synaptic function remains elusive. Here, we report that repetitive low-frequency stimulation activates BK channels through 12(S)HPETE, an arachidonic acid metabolite, produced downstream of postsynaptic metabotropic glutamate receptors (mGluRs) to trigger long-term depression (LTD) at CA3-CA1 synapses in hippocampal slices from P7-P10 mice. Activation of BK channels is subunit specific, as paxilline but not iberiotoxin blocked mGluR-LTD.

Objective: The ventral tegmental area (VTA), a pivotal hub in the brain's reward circuitry, receives inputs from the lateral hypothalamic area (LHA). However, it remains unclear whether melanin-concentrating hormone (MCH) and orexin-A (OX-A) neurons in the LHA exert individual or cooperative influence on palatable food consumption in the VTA. This study aims to investigate the modulatory role of MCH and OX-A in hedonic feeding within the VTA of high-fat diet (HFD) mice.
