Rat ventral caudal nerve as a model for long distance regeneration.

In the rat, tail nerves are the longest peripheral nerves in their body. We suggest that ventral caudal nerve (VCN) may serve as a model for studying nerve injury and long distance regeneration. For this purpose, we have studied the anatomy and morphometry of the VCN in control animals.

Characterisation of mesenchymal stem cells conditioned media obtained at different conditioning times: their effect on glial cells in scratch model.

In this study, the bone marrow mesenchymal stem cells conditioned media (BMMSC-CM) obtained by conditioning for 24(CM24), 48(CM48) and 72(CM72) hours was characterised. In vitro, the impact of BMMSC-CM on the astrocyte migratory response and oligodendrocyte density was evaluated using the scratch model. The proteomic profiles of individual secretomes were analysed by mass spectrometry and the concentrations of four selected neurotrophins (BDNF, NGF, GDNF and VEGF) were determined by ELISA.

Prevention and therapy of chemotherapy-induced peripheral neuropathy: a review of recent findings.

Chemotherapy-induced peripheral neuropathy is one of the most frequent dose-limiting side effects, observed in patients receiving antineoplastic agents, persisting for up to two years after completing treatment, greatly affecting both the course of chemotherapy and patients' quality of life. Approximately 20 to 85% of patients treated with neurotoxic chemotherapy will develop peripheral neuropathy and there is considerable variability in its severity among patients. The main symptoms are numbness, paresthesia, and burning pain in a "glove and stocking" distribution.

Precision spinal gene delivery-induced functional switch in nociceptive neurons reverses neuropathic pain.

Second-order spinal cord excitatory neurons play a key role in spinal processing and transmission of pain signals to the brain. Exogenously induced change in developmentally imprinted excitatory neurotransmitter phenotypes of these neurons to inhibitory has not yet been achieved. Here, we use a subpial dorsal horn-targeted delivery of AAV (adeno-associated virus) vector(s) encoding GABA (gamma-aminobutyric acid) synthesizing-releasing inhibitory machinery in mice with neuropathic pain.

Formaldehyde-hardened albumin as a non-penetrating embedding matrix for frozen and vibratome sectioning.

In this paper, we describe a protocol for a non-penetrating embedding matrix that can be used for frozen or vibratome sectioning of various formaldehyde-fixed tissue specimens. In our experiments, we wanted to prepare thin frozen sections from miniature specimens for fluorescent staining. As we could not achieve satisfactory results with any of the previously published methods, we have tried to modify the existing protocols, and systematically evaluated the effect of these modifications on the properties of the embedding matrix.
