OBJECTIVE To evaluate the changes in serum neuron specific enolase and protein S-100B, after carotid endarterectomy performed using the conventional technique with routine shunting and patch closure, or eversion technique without the use of shunt. MATERIALS AND METHODS Prospective non-randomized study included 43 patients with severe (>80%) carotid stenosis undergoing carotid endarterectomy i...

OBJECTIVE To prospectively study S-100B and neuron specific enolase (NSE) levels in subjects treated for severe head injury (sTBI), and investigate the prognostic value of these biomarkers. METHODS Subjects included in a prospective double blind randomised study for sTBI. INCLUSION CRITERIA Glasgow Coma Score (GCS) 10 mm...

BACKGROUND The possible injurious effect to the brain of heading in soccer is a matter of discussion. OBJECTIVE To determine whether standardised headings in soccer are associated with increased levels of biochemical markers for neuronal injury in cerebrospinal fluid (CSF) and serum. METHODS 23 male amateur soccer players took part in a heading training session involving heading a ball kick...

BACKGROUND Endothelial dysfunction might be involved in the development of cerebral vasospasm after aneurysmal subarachnoid haemorrhage (SAH). METHODS This prospective observational study of 48 SAH subjects and 23 control subjects examined associations between reactive hyperaemia index (RHI) measured by peripheral arterial tonometry and plasma concentrations of S-100B protein, nitrite/nitrate...

it usually points to a predisposing factor, as in this case, where a brain metastasis led to the formation of a hematoma (GelabertGonzález et al., 2012). Moreover, while the radiological image of the patient in their study shows a hematoma, it is of small and therefore leads one to question how this can be responsible for such a midline shift. This suggests that something more must be involved,...

BACKGROUND Fetal hypoxia is an important determinant of neonatal encephalopathy caused by birth asphyxia, in which hypoxia-induced free radical formation plays an important role. HYPOTHESIS Maternal treatment with allopurinol, will cross the placenta during fetal hypoxia (primary outcome) and reduce S-100B and free radical formation (secondary outcome). METHODS In a randomized, double-blind...

Rapeseed (Brassica napus L.) is sensitive to light quality. The factory production of rapeseed seedlings for vegetable use and for transplanting in the field requires an investigation of the responses of rapeseed to light quality. This study evaluated the responses of the leaf of rapeseed (cv. "Zhongshuang 11") to different ratios of red-photonflux (RPF) and blue-photonflux (BPF) from light emi...

Serum levels of S-100B were investigated as a marker for infarct volume and response to treatment following acute ischemic stroke in rabbits. Following subselective angiography, rabbits (n=31) were embolized by injection of a 3-day-old blood clot (0.6x4.0-mm) into the internal carotid artery. Treatment began 1-hr post-embolization, groups included: Control (n=8, embolization only), tissue plasm...
