Background: Paclitaxel-induced peripheral neuropathy (PIPN) is prevalent among patients receiving paclitaxel chemotherapy, which results in sensory abnormality as well as neuropathic pain. Conventional medications lack effectiveness on PIPN. Clinical trials identified beneficial effects of acupuncture on PIPN among patients receiving chemotherapy.

GDAP1, an atypical glutathione S-transferase, localizes to the outer mitochondrial membrane (OMM), regulating this organelle's dynamics, transport, and membrane contact sites (MCSs). It has been proposed that GDAP1 functions as a cellular redox sensor.

Current analgesics on the market exhibit a short duration of action and induce the production of inflammatory factors in tissues damaged by surgical procedures. Inflammatory factor production can create acidic environments, limiting drug delivery. In this study, we developed a novel injectable formulation comprising bupivacaine multivesicular liposomes of high osmotic pressure (H-MVL) and meloxicam nanocrystals (MLX) in a thermosensitive gel (H-MVL/MLX@GEL) adapted to the microenvironment for long-term postoperative analgesia.

A pathological condition in the peripheral nerve tissue, which provides the connection between the organism and the external environment, negatively affects the standard of living. The nerve tissue histotechnology is of serious importance both for scientific studies and for clinical diagnosis. The fixation, which is one of the leading procedures for histological examination of tissues, aims to preserve tissue morphology.

CXCL12 and CXCR4 proteins and mRNAs were monitored in the dorsal root ganglia (DRGs) of lumbar (L4-L5) and cervical (C7-C8) spinal segments of naïve rats, rats subjected to sham operation, and those undergoing unilateral complete sciatic nerve transection (CSNT) on post-operation day 7 (POD7). Immunohistochemical, Western blot, and RT-PCR analyses revealed bilaterally increased levels of CXCR4 protein and mRNA in both lumbar and cervical DRG neurons after CSNT. Similarly, CXCL12 protein levels increased, and CXCL12 mRNA was upregulated primarily in lumbar DRGs ipsilateral to the nerve lesion.
