Abstract: Tumor biopsies from 46 patients bearing gliomas, obtained neurosurgically in the period 1992–1998, were analyzed by high resolution 1H magnetic resonance spectroscopy (HR- 1H MRS), following retrospectively individual postsurgical Overall Survival up to 720 weeks.
The Overall Survival profile could be resolved in three groups; Short (shorter than 52 weeks, n = 19), Intermediate (between 53 and 364 weeks, n = 19) or Long (longer than 365 weeks, n = 8), respectively. Classical histopathological analysis assigned WHO grades II–IV to every biopsy but notably, some patients with low grade glioma depicted unexpectedly Short Overall Survival, while some patients with high grade glioma, presented unpredictably Long Overall Survival. To explore the reasons underlying these different responses, we analyzed HR-1H MRS spectra from acid extracts of the same biopsies
Inflammation takes place in both chronic and acute brain diseases and plays a key role in the development of several pathologies.

Abstract: Indeed, immune activation in the CNS is a common feature of brain injuries such as stroke, neurodegenerative diseases, and multiple sclerosis. Chronic inflammation leads to noxious effects on neurons and, thus,contributes to the pathophysiology of neurodegenerative diseases.Brain ischaemia is an acute injury that leads to the production of ROS and reactive nitrogen species (RNS), lipid peroxidation, blood–brain barrier (BBB) disruption, and exacerbated inflammation resultingin dramatic neuronal death ...

Abstract: Abstract Bell’s palsy is the most common diagnosis associated with facial nerve weakness or paralysis. However, not all patients with facial paresis/paralysis have Bell’spalsy. Other common causes include treatment of vestibular schwannoma, head and neck tumours, iatrogenic injuries, Herpes zoster, or trauma. The approach to each of these conditions varies widely.The purpose of this guide line is to provide clinicians with guidance on the treatment and monitoring of patients with different causes of facial paralysis.
