Tumors of the cerebellum and brainstem account for half of all brain tumors in children. The realization that cerebellar lesions produce clinically relevant intellectual disability makes it important to determine whether neuropsychological abnormalities occur in long-term survivors of pediatric cerebellar tumors. Little is known about the neurobehavioral(More)
It is known that diabetic mice are less sensitive to the analgesic effect of morphine. Some factor(s) derived from mononuclear cells, e.g. interleukin-1beta (IL-1beta), may be responsible for the diminished analgesic effect of morphine in diabetic mice. Therefore, we examined direct effects of IL-1beta, intracerebroventricularly (i.c.v.), on(More)
Apart from their involvement in the pathogenesis of demyelinating diseases such as multiple sclerosis, there is emerging evidence that matrix metalloproteinases (MMPs) also promote remyelination. We investigated region-specific expression patterns of 11 MMPs and 4 tissueinhibitors of metalloproteinases (TIMPs) in the cuprizone murine demyelination model.(More)
The aim of this study was to compare the safety, efficacy, tolerability, and the effects of atomoxetine and OROS-MPH on executive functions in children with ADHD. This study was an open-label study that only included two medication groups. Children were randomized to open-label atomoxetine or OROS-MPH for 12 weeks. Primary efficacy measures were T-DSM-IV-S,(More)
Nocardia brain abscess is a rare intracranial lesion and has been reported in immunocompromised patients. An optimal treatment approach has not been established. However, early diagnosis and appropriate antimicrobial therapy are very important factors for a good outcome. We report two unusual cases of Nocardia brain abscess simulating brain tumour in(More)
The effect of L-carnitine (LC) on brain stem auditory evoked potentials (BAEP), was examined in alloxan-diabetic rats. LC (200 mg kg-1, i.p., once daily) was given to diabetic rats starting from the third week after the induction of diabetes, lasting for 4 weeks. Age-matched non-diabetic rats served as controls. The latency of wave I and interpeak latency(More)

Unmanned Underwater Vehicles (UUVs) have gained popularity for the last decades, especially for the purpose of not risking human life in dangerous operations. On the other hand, underwater environment introduces numerous challenges in navigation, control and communication of such vehicles. Certainly, this fact makes the development of these vehicles more(More)
Angiogenesis that plays important roles in a variety of physiological processes is strictly delimited and finely tuned by a balance of pro-angiogenic and anti-angiogenic factors. Angiogenesis is essential for viability, growth, invasion and metastasis of tumors. The chorioallantoic membrane model is considered to be a valuable method for investigation of(More)
A 21-year-old woman was admitted due to altered mental status and hypothermia. The patient had a diagnosis of neuromyelitis optica (NMO) for 12 years and she was positive for serum anti-aquaporin 4 antibody. On admission, physical examination revealed coma with decerebration rigidity and poikilothermia. Magnetic resonance images of the brain revealed(More)
