A nociceptor-specific RNAi screen in larvae identifies RNA-binding proteins that regulate thermal nociception.

Nociception is the process by which sensory neurons detect and encode potentially harmful environmental stimuli to generate behavioral responses. Nociceptor neurons exhibit plasticity in which their sensitivity to noxious stimuli and subsequent ability to drive behavior may be altered by environmental conditions, injury, infection, and inflammation. In some cases, nociceptor sensitization requires regulated changes in gene expression, and recent studies have indicated roles for post-transcriptional mechanisms in regulating these changes as an aspect of nociceptor plasticity.

Nail Unit Melanoma Treated with Mohs Micrographic Surgery: Technique, Local Recurrence Rate, and Surgical Outcomes.

Background: Nail unit melanoma (NUM) is increasingly treated with digit-sparing surgery, but few published case series describe Mohs micrographic surgery (MMS) for NUM.

Objective: To describe the surgical technique, local recurrence rates, and reconstruction method for a large series of NUM treated with MMS using MART-1 immunostaining.

Methods: Biopsy-proven NUM treated with MMS-MART-1 were identified from a prospectively maintained database (2008-2023).

Alterations in Prefrontal Cortical Somatostatin Neurons in Schizophrenia: Evidence for Weaker Inhibition of Pyramidal Neuron Dendrites.

Background: Certain cognitive processes require inhibition provided by the somatostatin (SST) class of gamma-aminobutyric acid (GABA) neurons in the dorsolateral prefrontal cortex (DLPFC). This inhibition onto pyramidal neuron dendrites depends on both SST and GABA signaling. Although SST mRNA levels are lower in the DLPFC in schizophrenia, it is not known if SST neurons exhibit alterations in the capacity to synthesize GABA, principally via the 67-kilodalton isoform of glutamic acid decarboxylase (GAD67).

Treatment of antebrachial deformities secondary to premature closure of the distal radial physis using circular external skeletal fixation and distraction osteogenesis in skeletally immature dogs.

Objective: To report clinical outcomes of skeletally immature dogs with antebrachial deformities secondary to premature closure of the distal radial physis (PCDRP) treated with angular corrections and distraction osteogenesis using circular external skeletal fixation (CESF).

Study Design: Retrospective multi-institutional case series.

Animals: A total of 12 client-owned dogs with premature distal radial physeal closure.
