Chronic headaches and pain are prevalent in those who are exposure to blast events, yet there is a gap in fundamental data that identifies the pathological mechanism for the chronification of pain. Blast-related post-traumatic headaches (PTH) are understudied and chronic pain behaviors in preclinical models can be vital to help elucidate PTH mechanisms. The descending pain modulatory system controls pain perception and involves specific brain regions such as the cortex, thalamus, pons, and medulla.

Background: Luteolin, a natural flavonoid, exhibits antioxidant and anti-inflammatory properties and has been investigated for potential health benefits. Its focus on migraine management arises from its ability to mitigate neuroinflammation, a key factor in migraine attacks.
Methods: pkCSM and Swiss ADME were employed to assess luteolin's pharmacokinetic properties, revealing challenges such as low water solubility and limited skin permeability.

Lumbar intervertebral disc degeneration is thought to be the main cause of low back pain, although the mechanisms by which it occurs and leads to pain remain unclear. In healthy adult discs, vessels and nerves are present only in the outer layer of the annulus fibrosus and in the bony endplate. Animal models, and histological and biomechanical studies have shown that annulus tear or endplate injury is the initiating factor for painful disc degeneration.

In healthy intervertebral discs (IVDs), nerves and blood vessels are present only in the outer annulus fibrosus, while in degenerative IVDs, a large amount of nerve and blood vessel tissue grows inward. Evidence supports that neurogenic inflammation produced by neuropeptides such as substance P and calcitonin gene related peptide released by the nociceptive nerve fibers innervating the IVDs plays a crucial role in the process of IVD degeneration. Recently, non-neuronal cells, including IVD cells and infiltrating immune cells, have emerged as important players in neurogenic inflammation.
