It has long been recognised that the neurobiochemistry of hypoglycaemic brain injury differs markedly from hypoxic-ischaemic injury. The neuropathology may also be distinctive. Such distinctive changes, aiding discrimination injury, are though commonly absent even in cases biochemically proved profound hypoglycaemia. Neuronal depletion or necrosis only observed 29% cases. Autopsy findings suspe...

Diffuse brain injury (DBI) is a consequence of traumatic brain injury evoked via rapid acceleration-deceleration of the cranium, giving rise to subtle pathological changes appreciated best at the microscopic level. DBI is believed to be comprised by diffuse axonal injury and other forms of diffuse vascular change. The potential, however, that the same forces can also directly injure neuronal so...

The desert hedgehog (Dhh) signaling pathway is involved in the development of peripheral nerves (PNs). Dhh-null mice show abnormal neuronal development and perineurial barrier function. As it was previously shown that dhh is mainly expressed in developmental nerves and Sonic hedgehog protein (dhh homologous) has therapeutic effects in neuronal survival, we attempted to investigate the possible ...

Background: Bone marrow stromal cells (BMSC) are used as a source for cell therapy in different model for neurological disorder such as stroke and spinal cord injury. However, the transdifferentiation of BMSC into cholinergic phenotype requires more investigation. Methods: BMSC were isolated from adult rats, pre-induced with β-mercaptoethanol (BME) and followed by nerve growth factor (NGF) indu...

Protracted elevation in intracellular calcium caused by the activation of the N-methyl-d-aspartate receptor is the main cause of glutamate excitotoxic injury in stroke. However, upon excitotoxic injury, despite the presence of calcium entry antagonists, calcium unexpectedly continues to enter the neuron, causing extended neuronal depolarization and culminating in neuronal death. This phenomenon...

Objective: Arsenic, an environmental pollutant, decreases neuronal migration as well as cellular maturation and inhibits the proliferation of neural progenitor cells. Curcumin has been described as an antioxidant and neuroprotective agent with strong therapeutic potential in some neurological disorders. Human adipose-derived stem cells (hADSCs), a source of multipotent stem cells, can self-rene...

Traumatic brain injury is considered as one of the main causes of morbidity and mortality worldwide. Apart from primary mechanical injury, Secondary injuries due to inflammation and apoptosis result in great neuronal damage. Current treatments are not able to regenerate the damaged part and prevent future sequels. Using human stem cells with self-assembling scaffolds may be promising in treatme...
