Inducing phospholipase A2 and cyclooxygenase-2 expression and prostaglandins' production of human dental pulp cells by activation of NOD receptor and its downstream signaling.

Dental caries with invasion and infection by microorganisms may induce pulpitis and intolerable pain. L-Ala-γ-D-Glu-mDAP (TriDAP) is a DAP-comprising muramyl tripeptide and a peptidoglycan degradation product found in gram-negative pulpal pathogens. TriDAP activates nucleotide-binding oligomerization domain1/2 (NOD1/NOD2) and induces tissue inflammatory responses.

In vivo AAV9-Myo7a gene rescue restores hearing and cholinergic efferent innervation in inner hair cells.

In the mammalian cochlea, sensory hair cells are crucial for the transduction of acoustic stimuli into electrical signals, which are then relayed to the central auditory pathway via spiral ganglion neuron (SGN) afferent dendrites. The SGN output is directly modulated by inhibitory cholinergic axodendritic synapses from the efferent fibers originating in the superior olivary complex. When the adult cochlea is subjected to noxious stimuli or aging, the efferent system undergoes major rewiring, such that it reestablishes direct axosomatic contacts with the inner hair cells (IHCs), which occur only transiently during prehearing stages of development.

War at Sea: Burn Care Challenges-Past, Present and Future.

Throughout history, seafarers have been exposed to potential thermal injuries during naval warfare; however, injury prevention, including advances in personal protective equipment, has saved lives. Thankfully, burn injuries have decreased over time, which has resulted in a significant clinical skills gap. Ships with only Role 1 (no surgical capability) assets have worse outcomes after burn injury compared to those with Role 2 (surgical capability) assets.
