Clinical implications of leukocyte infiltration at the choroid plexus in (neuro)inflammatory disorders.
The choroid plexus (CP) is a highly vascularized organ located in the brain ventricles and contains a single epithelial cell layer forming the blood-cerebrospinal fluid barrier (BCSFB). This barrier is crucial for immune surveillance in health and is an underestimated gate for entry of immune cells during numerous infl...

The degeneration of dopaminergic synapses in Parkinson's disease: A selective animal model.
Available evidence increasingly suggests that the degeneration of dopamine neurons in Parkinson's disease starts in the striatal axons and synaptic terminals. A selective procedure is described here to study the mechanisms involved in the striatal denervation of dopaminergic terminals. This procedure can also be used t...

Immunization with a Myelin-Derived Antigen Activates the Brain's Choroid Plexus for Recruitment of Immunoregulatory Cells to the CNS and Attenuates Disease Progression in a Mouse Model of ALS.
Amyotrophic lateral sclerosis (ALS) is a devastating fatal motor neuron disease, for which there is currently no cure or effective treatment. In this disease, local neuroinflammation develops along the disease course and contributes to its rapid progression. In several models of CNS pathologies, circulating immune cell...

Early magnetic resonance imaging predictors of clinical progression after 48 months in clinically isolated syndrome patients treated with intramuscular interferon &#x3b2;-1a.
Our aim was to identify early imaging surrogate markers of clinical progression in patients after the first demyelinating event suggestive of multiple sclerosis treated with weekly intramuscular interferon &#x3b2;-1a. In a prospective observational study, the predictive role of baseline and 6-month changes in magnetic ...

Mitochondrial networks in cardiac myocytes reveal dynamic coupling behavior.
Oscillatory behavior of mitochondrial inner membrane potential (&#x394;&#x3a8;m) is commonly observed in cells subjected to oxidative or metabolic stress. In cardiac myocytes, the activation of inner membrane pores by reactive oxygen species (ROS) is a major factor mediating intermitochondrial coupling, and ROS-induced...

Decision-making under explicit risk is impaired in multiple sclerosis: relationships with ventricular width and disease disability.
Decision-making is an essential function of everyday life. Decision-making under explicit risk requires developing advantageous decision strategies based on fixed outcomes (e.g., probabilities of winning or losing a bet). Decision-making and its neural substrates have been rarely studied in MS. We expected performance ...

Misuse and modification of fireworks with fatal injury.
Fireworks deaths are a rare event in the United States with minor injuries comprising most adverse events. We report the case of misuse and modification of a large "mortar" firework with fatal results. In this case, the firework charge was modified with additional fuses and placed into the launcher upside down. The dec...

Thyroglossal Duct Cyst Associated with Xanthogranulomatous Inflammation.
Xanthogranulomatous inflammation (XGI) is an uncommon destructive chronic inflammatory process mainly occurring in the kidney and gallbladder, characterized by the accumulation of foamy histiocytes, multinucleated giant cells (Touton type), cholesterol clefts and chronic inflammatory cells. The head and neck region is ...

The SVZ and Its Relationship to Stem Cell Based Neuro-oncogenesis.
Gliomas are primary cancers of the brain and the most lethal cancers known to man. In recent years the discovery of germinal regions in the postnatal brain containing neuronal stem and progenitor cell populations has led to the hypothesis that these cells may themselves serve as an origin of brain tumors. Stem cells th...

Regulation of subventricular zone-derived cells migration in the adult brain.
The subventricular zone of the lateral ventricles (SVZ) is the largest source of neural stem cells (NSCs) in the adult mammalian brain. Newly generated neuroblasts from the SVZ form cellular chains that migrate through the rostral migratory stream (RMS) into the olfactory bulb (OB), where they become mature neurons. Mi...

The Infundibular Recess Passes through the Entire Pituitary Stalk.
The infundibular recess (IR), commonly illustrated as a V-shaped hollow in the sagittal view, is recognized as a small extension of the third ventricle into the pituitary stalk. The precise morphology of the human IR is unknown. The present study sought to delineate the morphology of the IR using magnetic resonance ima...

Atypical extraventricular neurocytoma in a 3-year-old girl: case report with radiological-pathological correlation.
Extraventricular neurocytoma (EVN) is a rare neuronal tumor histologically similar to central neurocytoma but arising in the brain parenchyma outside the ventricles. The minority of EVNs show atypical features including increased proliferative index, microvascular proliferation, or necrosis, and are called atypical EVN...

Analysis of frequency of deep white matter metastasis on cerebral MRI.
Supratentorial white matter is an important part of the brain and a major site of detrimental effects after whole brain radiotherapy (WBRT). It is not known if prevalence of metastases in white matter justifies standard inclusion of white matter in whole brain treatment. In this retrospective analysis we examined the f...

Electrophysiological effect and the gating mechanism of astragaloside IV on L-type Ca(2+) channels of guinea-pig ventricular myocytes.
Astragaloside IV (AS-IV) is one of the main active ingredients of Astragalus membranaceus. This study is aimed to investigate AS-IV&#x5f3;s effects on Ca(2+) channel activity of single cardiomyocytes and single Ca(2+) channels. Whole-cell Ca(2+) currents in freshly dissociated cardiomyocytes were measured using the who...

Insulin improves memory and reduces chronic neuroinflammation in the hippocampus of young but not aged brains.
The role of insulin in the brain is still not completely understood. In the periphery, insulin can decrease inflammation induced by lipopolysaccharide (LPS); however, whether insulin can reduce inflammation within the brain is unknown. Experiments administrating intranasal insulin to young and aged adults have shown th...

An intraventricular meningioma and recurrent astrocytoma collision tumor: a case report and literature review.
Intracranial meningioma and glioma collision tumors are relatively uncommon and are even more rarely located within the ventricles.</AbstractText>Here, we report a case of a patient with an intraventricular meningioma and astrocytoma collision tumor. A 39-year-old man previously underwent excision of an astrocytoma in ...

Long-term temozolomide might be an optimal choice for patient with multifocal glioblastoma, especially with deep-seated structure involvement: a case report and literature review.
Multifocal glioblastoma is an uncommon and refractory subtype of high-grade glioma since the burden of masses could not be eliminated simply by operation, and it is getting even harder to control if some deep structures, like thalamus and pineal region, are involved.</AbstractText>Here we report a case of a 30-year-old...

Effects of sodium butyrate on aversive memory in rats submitted to sepsis.
Epigenetic mechanisms are involved in normal behavior and are implicated in several brain neurodegenerative conditions, psychiatric and inflammatory diseases as well. Moreover, it has been demonstrated that sepsis lead to an imbalance in acetylation of histones and that histone deacetylase inhibitors (HDACi) can revers...

Lumican deficiency results in cardiomyocyte hypertrophy with altered collagen assembly.
The ability of the heart to adapt to increased stress is dependent on the modification of its extracellular matrix (ECM) architecture that is established during postnatal development as cardiomyocytes differentiate, a process that is poorly understood. We hypothesized that the small leucine-rich proteoglycan (SLRP) lum...

Lin41/Trim71 is essential for mouse development and specifically expressed in postnatal ependymal cells of the brain.
Lin41/Trim71 is a heterochronic gene encoding a member of the Trim-NHL protein family, and is the original, genetically defined target of the microRNA let-7 in C. elegans. Both the LIN41 protein and multiple regulatory microRNA binding sites in the 3' UTR of the mRNA are highly conserved from nematodes to humans. Funct...
