Subarachnoid hemorrhage in C57BL/6J mice increases motor stereotypies and compulsive-like behaviors.

Objective: Long-term behavioral, mood, and cognitive deficits affect over 30% of patients with subarachnoid hemorrhage (SAH). The aim of the present study was to examine the neurobehavioral outcomes following endovascular perforation induced SAH in mice.

Methods: C57BL/6 J (B6) mice were exposed to endovascular perforation induced SAH or control surgery.

Oral surgery with nasotracheal intubation in a patient with ectodermal dysplasia.

Ectodermal dysplasias are a rare group of heritable disorders involving the ectodermal derivatives with only a few published reports involving its anaesthetic management. We present the case of a 16-year-old boy with ectodermal dysplasia presented for elective oral surgery under general anaesthesia with a surgeon preference for nasotracheal intubation to provide adequate surgical exposure. The patient had successful nasal flexible bronchoscopic intubation despite challenging tracheal intubation conditions.

Heparanase promotes neuroinflammatory response during subarachnoid hemorrhage in rats.

Background: Heparanase, a mammalian endo-β-D-glucoronidase that specifically degrades heparan sulfate, has been implicated in inflammation and ischemic stroke. However, the role of heparanase in neuroinflammatory response in subarachnoid hemorrhage (SAH) has not yet been investigated. This study was designed to examine the association between heparanase expression and neuroinflammation during subarachnoid hemorrhage.

Bevacizumab is superior to Temozolomide in causing mitochondrial dysfunction in human brain tumors.

Objective: Current chemotherapy treatments available for treating high-grade brain tumors, Temozolomide (TMZ) or Bevacizumab (BEV), not only have specific anti-tumor mechanisms, but also have an effect on mitochondria. However, effects of both drugs on mitochondria isolated from human brain tumors have not been thoroughly investigated. This study determined the direct effects of TMZ and BEV as well as the neurotoxic condition (calcium overload), on the function of mitochondria and compared these effects on mitochondria isolated from low- and high-grade human brain tumors.

VAP-1 blockade prevents subarachnoid hemorrhage-associated cerebrovascular dilating dysfunction via repression of a neutrophil recruitment-related mechanism.

Our previous findings indicated that in rats subjected to subarachnoid hemorrhage (SAH), suppression of post-SAH neuroinflammation via vascular adhesion protein-1 (VAP-1) blockade provides significant neuroprotection. We and others have reported that neuroinflammation contributes to cerebral microvascular impairment. Thus, in the present study, we tested the hypotheses that: (1) treatment with LJP-1586, a selective VAP-1 blocker, prevents SAH-associated pial arteriolar dilating dysfunction; and (2) the vasculoprotective effect of LJP-1586 arises from inhibiting SAH-elicited neutrophil recruitment.

Current evidence of temozolomide and bevacizumab in treatment of gliomas.

Objective: This review article summarizes in vitro, in vivo, and clinical evidence pertaining to temozolomide (TMZ) and bevacizumab (BEV) efficacy and mechanism of action in gliomas.

Methods: Relevant publications published before June 2013 in PubMed database were reviewed.

Results: Temozolomide and BEV are current chemotherapeutic agents treating patients with high-grade glioma, including glioblastoma.
