The changes in neuronal nitric oxide synthases (nNOS) in the dorsal penile nerves (DPNs) are consistent with cavernous nerve (CN) injury in rat models. However, the anatomical relationship and morphological changes between the minor branches of the DPNs and the CNs after injury have never been clearly explored. There were forty 12 week old male Sprague-Dawley rats receiving bilateral cavernous nerve injury (BCNI). Erectile function of intracavernous pressure and mean arterial pressure were measured. The histology and ultrastructure with H&E stain, Masson's trichrome stain and immunohistochemical stains were applied on the examination of CNs and DPNs...

Diabetic peripheral neuropathy (DPN) is the most common chronic neurological complication of diabetes1 . Small and large peripheral nerve fibers may be involved in DPN. Large nerve fiber damage causes paresthesia, sensory loss, and muscle weakness and small nerve fiber damage is associated with pain, anesthesia, foot ulcer, and autonomic symptoms. However, the exact pathogenic mechanisms and diagnostic criteria for DPN are not firmly established currently. The present DPN prevention, diagnosis, and treatment strategies are incomplete and unsuccessful due to the various pathogenesis of systemic and cellular disturbance in glucose and lipid metabolism...

Sex is an influential factor regarding pathophysiology and therapeutic response in human disease. Pachyonychia congenita (PC) is caused by mutations in keratin genes and typified by dystrophic lesions affecting nails, glands, oral mucosa, and palmar-plantar epidermis. Painful palmar-plantar keratoderma (PPK) severely impair mobility in PC. Mice genetically null for keratin 16 (Krt16), one of the genes mutated in PC, develop PC-like PPK. In male Krt16-/- mice, oxidative stress associated with impaired glutathione synthesis and NRF2-dependent gene expression precedes PPK onset, which can be prevented by topical sulforaphane (SF)-mediated activation of NRF2 (Kerns et al...

Diabetic polyneuropathy (DPN) is the most frequent and prevalent chronic complication of diabetes mellitus (DM). The state of persistent hyperglycemia leads to an increase in the production of cytosolic and mitochondrial reactive oxygen species (ROS) and favors deregulation of the antioxidant defenses that are capable of activating diverse metabolic pathways which trigger the presence of nitro-oxidative stress (NOS) and endoplasmic reticulum stress. Hyperglycemia provokes the appearance of micro- and macrovascular complications and favors oxidative damage to the macromolecules (lipids, carbohydrates, and proteins) with an increase in products that damage the DNA...

BACKGROUND: Several anticonvulsant drugs are used in the management of neuropathic pain. Oxcarbazepine is an anticonvulsant drug closely related to carbamazepine. Oxcarbazepine has been reported to be efficacious in the treatment of neuropathic pain, but evidence from randomised controlled trials (RCTs) is conflicting. Oxcarbazepine is reportedly better tolerated than carbamazepine. This is the first update of a review published in 2013. OBJECTIVES: To assess the benefits and harms of oxcarbazepine for different types of neuropathic pain...

The TRIM-NHL protein Brain tumor (Brat) acts as a tumor suppressor in the Drosophila brain, but how it suppresses tumor formation is not completely understood. Here, we combine temperature-controlled brat RNAi with transcriptome analysis to identify the immediate Brat targets in Drosophila neuroblasts. Besides the known target Deadpan (Dpn), our experiments identify the transcription factor Zelda (Zld) as a critical target of Brat. Our data show that Zld is expressed in neuroblasts and required to allow re-expression of Dpn in transit-amplifying intermediate neural progenitors...

Estrogen (17β-estradiol) is essential for normal growth and differentiation in the mammary gland. Previous investigations have revealed that estrogen receptor alpha (ERα) plays a critical role in breast cancer. More recently, observations regarding the widespread expression of ERβ-like proteins in normal and neoplastic mammary tissues have suggested that ERβ is also involved in the mentioned pathology. Design of new drugs both steroidal and nonsteroidal that target any of these receptors represents a promise to treat breast cancer...
