Pathologies occupying the interventricular foramen (foramen of Monro - FM) or the anterior part of lateral ventricle (LV) are accessed by the transcortical or transcallosal route. As severing of rostral corpus callosum has been deemed inferior to cortical incision, the approaches through various points of frontal lobe ...

Early postnatal exposure to ultrafine particulate matter air pollution: persistent ventriculomegaly, neurochemical disruption, and glial activation preferentially in male mice.
Air pollution has been associated with adverse neurological and behavioral health effects in children and adults. Recent studies link air pollutant exposure to adverse neurodevelopmental outcomes, including increased risk for autism, cognitive decline, ischemic stroke, schizophrenia, and depression.</AbstractText>We so...

Acetate supplementation modulates brain adenosine metabolizing enzymes and adenosine A&#x2082;A receptor levels in rats subjected to neuroinflammation.
Acetate supplementation reduces neuroglia activation and pro-inflammatory cytokine expression in rat models of neuroinflammation and Lyme neuroborreliosis. Because single-dose glyceryl triacetate (GTA) treatment increases brain phosphocreatine and reduces brain AMP levels, we postulate that GTA modulates adenosine meta...

A fatal case of JC virus meningitis presenting with hydrocephalus in a human immunodeficiency virus-seronegative patient.
JC virus (JCV) is the etiologic agent of progressive multifocal leukoencephalopathy, JCV granule cell neuronopathy, and JCV encephalopathy. Whether JCV can also cause meningitis has not yet been demonstrated. We report a case of aseptic meningitis resulting in symptomatic hydrocephalus in a human immunodeficiency virus...

Automatic cardiac segmentation using semantic information from random forests.
We propose a fully automated method for segmenting the cardiac right ventricle (RV) from magnetic resonance (MR) images. Given a MR test image, it is first oversegmented into superpixels and each superpixel is analyzed to detect the presence of RV regions using random forest (RF) classifiers. The superpixels containing...

Clocks for all seasons: unwinding the roles and mechanisms of circadian and interval timers in the hypothalamus and pituitary.
Adaptation to the environment is essential for survival, in all wild animal species seasonal variation in temperature and food availability needs to be anticipated. This has led to the evolution of deep-rooted physiological cycles, driven by internal clocks, which can track seasonal time with remarkable precision. Evid...

Single acute stress-induced progesterone and ovariectomy alter cardiomyocyte contractile function in female rats.
To assess how ovarian-derived sex hormones (in particular progesterone) modify the effects of single acute stress on the mechanical and biochemical properties of left ventricular cardiomyocytes in the rat.</AbstractText>Non-ovariectomized (control, n=8) and ovariectomized (OVX, n=8) female rats were kept under normal c...

Imaging genomic mapping of an invasive MRI phenotype predicts patient outcome and metabolic dysfunction: a TCGA glioma phenotype research group project.
Invasion of tumor cells into adjacent brain parenchyma is a major cause of treatment failure in glioblastoma. Furthermore, invasive tumors are shown to have a different genomic composition and metabolic abnormalities that allow for a more aggressive GBM phenotype and resistance to therapy. We thus seek to identify thos...

Polymicrogyria: a common and heterogeneous malformation of cortical development.
Polymicrogyria (PMG) is one of the most common malformations of cortical development. It is characterized by overfolding of the cerebral cortex and abnormal cortical layering. It is a highly heterogeneous malformation with variable clinical and imaging features, pathological findings, and etiologies. It may occur as an...

A computational model that predicts reverse growth in response to mechanical unloading.
Ventricular growth is widely considered to be an important feature in the adverse progression of heart diseases, whereas reverse ventricular growth (or reverse remodeling) is often considered to be a favorable response to clinical intervention. In recent years, a number of theoretical models have been proposed to model...

The microinjection of a cannabinoid agonist into the accumbens shell induces anxiogenesis in the elevated plus-maze.
This study investigated the effect of a cannabinoid agonist injected into the shell region of the nucleus accumbens (nAcb shell) on anxiety-related behaviors. The animals (male Wistar rats) were unilaterally microinjected with either ACEA (arachidonyl-2'-chloroethylamide a CB1 receptor agonist) at doses of 0.005, 0.05 ...

The Welsh study of mothers and babies: protocol for a population-based cohort study to investigate the clinical significance of defined ultrasound findings of uncertain significance.
Improvement in ultrasound imaging has led to the identification of subtle non-structural markers during the 18 - 20&#xa0;week fetal anomaly scan, such as echogenic bowel, mild cerebral ventriculomegaly, renal pelvicalyceal dilatation, and nuchal thickening. These markers are estimated to occur in between 0.6% and 4.3% ...

Chronic toluene exposure induces cell proliferation in the mice SVZ but not migration through the RMS.
Abuse of toluene-containing inhalants is associated to various cognitive impairments that have been partly associated to deviation of the hippocampal neurogenesis processes during adulthood. In the present study we analyzed the effect of chronic toluene exposure (6000ppm) on cell proliferation and migration in the othe...

How do we measure pathology in PAH (lung and RV) and what does it tell us about the disease.
The current understanding of the pathology that underlies pulmonary vascular and right ventricular remodeling in pulmonary hypertension is discussed. Although recent studies underscored the importance of intima and media remodeling and, for the first time, the relevance of perivascular inflammation, much is needed to m...

Primary central nervous system cytotoxic T-cell lymphoma mimicking demyelinating disease.
A 40-year-old man visited to our hospital due to progressive right hemiparesis. Magnetic resonance imaging demonstrated a heterogeneous contrast-enhanced lesion in the left basal ganglia with compression of the ventricles. A brain biopsy did not demonstrate central nervous system (CNS) lymphoma, although acute demyelin...

[Use of intracranial translucency measurement in first trimester, beyond spina bifida].
The intracranial translucency (IT) is described as echolucid space located in the fetal central nervous system corresponding to the fourth ventricle. Alteration in the first trimester is associated with neural tube defects (NTDs).</AbstractText>To describe as part of the ultrasonographic assessment of the first quarter...

Identification of distinct ChAT&#x207a; neurons and activity-dependent control of postnatal SVZ neurogenesis.
Postnatal and adult subventricular zone (SVZ) neurogenesis is believed to be primarily controlled by neural stem cell (NSC)-intrinsic mechanisms, interacting with extracellular and niche-driven cues. Although behavioral experiments and disease states have suggested possibilities for higher level inputs, it is unknown w...

Flaviviruses are neurotropic, but how do they invade the CNS?
Flaviruses (FV) are RNA viruses carried by mosquitoes. Neurological signs including acute encephalitis, meningitis and acute flaccid paralysis develop in a small percentage of infected individuals; long term sequlae are, Parkinsonism, dystonias and cognitive changes. FV neuroinfection is neurotropic involving subcortic...

Galen and the beginnings of Western physiology.
Galen (129-c. 216 AD) was a key figure in the early development of Western physiology. His teachings incorporated much of the ancient Greek traditions including the work of Hippocrates and Aristotle. Galen himself was a well-educated Greco-Roman physician and physiologist who at one time was a physician to the gladiato...

Endoscopic third ventriculostomy for hydrocephalus due to tectal glioma.
Tectal gliomas commonly present with hydrocephalus from obstruction of the aqueduct of Sylvius. The creation of a ventriculostomy in the floor of the third ventricle (ETV) has been previously reported to by-pass aqueduct obstruction. The goal of this study was to determine the safety and efficacy of ETV in the presence...
