Keyhole epilepsy surgery: corticoamygdalohippocampectomy for mesial temporal sclerosis.
Surgical approaches for medically refractory mesial temporal lobe epilepsy (MTLE) that previously have been reported include anterior temporal lobectomy (ATL), transcortical selective amygdalohippocampectomy, transsylvian amygdalohippocampectomy, and subtemporal amygdalohippocampectomy. Each approach has its advantages...

14-3-3&#x3b6; deficient mice in the BALB/c background display behavioural and anatomical defects associated with neurodevelopmental disorders.
Sequencing and expression analyses implicate 14-3-3&#x3b6; as a genetic risk factor for neurodevelopmental disorders such as schizophrenia and autism. In support of this notion, we recently found that 14-3-3&#x3b6;(-/-) mice in the Sv/129 background display schizophrenia-like defects. As epistatic interactions play a s...

Estrogen regulation of the transient outward K(+) current involves estrogen receptor &#x3b1; in mouse heart.
We have previously shown that androgens upregulate cardiac K(+) channels and shorten repolarization. However, the effects that estrogens (E2) and estrogen receptors (ER) might have on the various repolarizing K(+) currents and underlying ion channels remain incompletely understood. Accordingly, our objective was to ver...

Visualizing and quantifying Pseudomonas aeruginosa infection in the hindbrain ventricle of zebrafish using confocal laser scanning microscopy.
Pseudomonas aeruginosa colonizes surfaces using a stepwise process that involves several phases, including attachment, production of exopolysaccharides, formation of microcolonies and the eventual development of biofilms. This process has been extensively characterized in vitro using both light and electron microscopic...

Central acylated ghrelin improves memory function and hippocampal AMPK activation and partly reverses the impairment of energy and glucose metabolism in rats infused with &#x3b2;-amyloid.
Ghrelin is a gastric hormone released during the fasting state that targets the hypothalamus where it induces hunger; however, emerging evidence suggests it may also affect memory function. We examined the effect of central acylated-ghrelin and DES-acetylated ghrelin (native ghrelin) on memory function and glucose meta...

Midline Brain Abnormalities Across Psychotic and Mood Disorders.
Patients with schizophrenia are known to have increased prevalence of abnormalities in midline brain structures, such as a failure of the septum pellucidum to fuse (cavum septum pellucidum) and the absence of the adhesio interthalamica. This is the first study to investigate the prevalence of these abnormalities across...

Episodic ventriculomegaly due to hypernatremia mimicking shunt malfunction: case report.
Patients with shunted hydrocephalus presenting with altered mental status and ventriculomegaly are generally considered to be in shunt failure requiring surgical treatment. The authors describe a case of shunted hydrocephalus secondary to a disseminated neuroectodermal tumor in a pediatric patient in whom rapid fluctua...

Parkinsonism Improved With Levodopa After Endoscopic Third Ventriculostomy in Shunted Hydrocephalus Due to Aqueductal Stenosis.
Levodopa-responsive parkinsonism has been reported following ventriculoperitoneal (VP) shunt in patients with obstructive hydrocephalus due to aqueductal stenosis. It has been thought to arise from injury to the global rostral midbrain including the nigrostriatal pathway by a transtentorial pressure gradient. We presen...

Giant Mesencephalic Dilated Virchow Robin Spaces Causing Obstructive Hydrocephalus Treated by Endoscopic Third Ventriculostomy.
Virchow Robin spaces (VRSs) are perivascular spaces that act as drainage pathways for interstitial fluid. Dilatation of VRSs is visible on magnetic resonance images in asymptomatic individuals. However, giant dilatation of VRSs (dVRSs) is very rare. Such giant dVRSs may produce a pressure effect on surrounding structur...
