The smooth pebbled appearance of the CEREBRAL CORTEX with a thickened cortex and reduced and abnormal white matter, which results from migration of heterotopic neurons beyond the marginal zone into the leptomeninges through gaps in the external BASEMENT MEMBRANE. There is also enlarged ventricles, underdeveloped BRAINSTEM and cerebellum, and absence of the CORPUS CALLOSUM. These abnormalities occur as a syndrome without other birth defects (cobblestone complex) or in other syndromes associated with congenital MUSCULAR DYSTROPHY, often involving the eye, such as the Walker-Warburg Syndrome, Fukuyama congenital muscular dystrophy, and muscle-eye-brain disease.
A "smooth brain" malformation of the CEREBRAL CORTEX resulting from abnormal location of developing neurons during corticogenesis. It is characterized by an absence of normal convoluted indentations on the surface of the brain (agyria), or fewer and shallower indentations (pachygryia). There is a reduced number of cortical layers, typically 4 instead of 6, resulting in a thickened cortex, and reduced cerebral white matter that is a reversal of the normal ratio of cerebral white matter to cortex.

These include malformations arising from abnormal neuronal and glial CELL PROLIFERATION or APOPTOSIS (Group I); abnormal neuronal migration (Group II); and abnormal establishment of cortical organization (Group III). Many INBORN METABOLIC BRAIN DISORDERS affecting CNS formation are often associated with cortical malformations. They are common causes of EPILEPSY and developmental delay.
A disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns (e.g., nocturnal epilepsy). (From Adams et al., Principles of Neurology, 6th ed, p313)
Conditions characterized by recurrent paroxysmal neuronal discharges which arise from a focal region of the brain. Partial seizures are divided into simple and complex, depending on whether consciousness is unaltered (simple partial seizure) or disturbed (complex partial seizure). Both types may feature a wide variety of motor, sensory, and autonomic symptoms. Partial seizures may be classified by associated clinical features or anatomic location of the seizure focus. A secondary generalized seizure refers to a partial seizure that spreads to involve the brain diffusely. (From Adams et al., Principles of Neurology, 6th ed, pp317)

Disorders comprising a spectrum of brain malformations representing the paradigm of a diffuse neuronal migration disorder. They result in cognitive impairment; SEIZURES; and HYPOTONIA or spasticity. Mutations of two genes, LIS1, the gene for the non-catalytic subunit of PLATELET-ACTIVATING FACTOR ACETYLHYDROLASE IB; and DCX or XLIS, the gene for doublecortin, have been identified as the most common causes of disorders in this spectrum. Additional variants of classical (Type I) lissencephaly have been linked to RELN, the gene for reelin, and ARX, the gene for aristaless related homeobox protein. (From Leventer, R.J., et al, Mol Med Today. 2000 Jul;6(7):277-84 and Barkovich, A.J., et al, Neurology. 2005 Dec 27;65(12):1873-87.)
A lipoprotein-associated PHOSPHOLIPASE A2 which modulates the action of PLATELET ACTIVATING FACTOR by hydrolyzing the SN-2 ester bond to yield the biologically inactive lyso-platelet-activating factor.

Abnormal posttranslational processing of dystroglycan is associated with congenital muscular dystrophies with CNS involvement ranging from mental retardation to structural defects, including cobblestone (type II) lissencephaly and hydrocephalus (Muntoni and Voit, 2004; Barresi and Campbell, 2006). Defects in neuron migration that resemble cobblestone lissencephaly also occur in mice with tissue-specific deletion of dystroglycan (Moore et al., 2002; Satz et al., 2008). Prior studies indicate that dystroglycan is broadly expressed in neurons and glia of the developing and adult brain (Zaccaria et al., 2001; Henion et al., 2003; Ohtsuka-Tsurumi et al., 2004); however, little is known about its cellular functions. In this study we provide genetic evidence of distinct roles for glial dystroglycan in development, and for neuronal dystroglycan in synaptic plasticity.. We previously showed that MOX2-Cre mediated deletion of dystroglycan (MORE-DG-null) in all epiblast-derived tissues produces severe ...

TY - JOUR. T1 - Expression of p73 and Reelin in the Developing Human Cortex. AU - Meyer, Gundela. AU - Perez-Garcia, Carlos Gustavo. AU - Abraham, Hajnalka. AU - Caput, Daniel. PY - 2002/6/15. Y1 - 2002/6/15. N2 - Cajal-Retzius (CR) cells of the developing neocortex secrete Reelin (Reln), a glycoprotein involved in neuronal migration. CR cells selectively express p73, a p53 family member implicated in cell survival and apoptosis. Immunocytochemistry in prenatal human telencephalon reveals a complex sequence of migration waves of p73- and Reln-immunoreactive (IR) neurons into the cortical marginal zone (MZ). At early preplate stages, p73/Reln-IR cells arise in distinct sectors of the telencephalon, including cortical primordium and ganglionic eminences. After the appearance of the cortical plate, further p73/Reln-IR cells originate in the medial periolfactory forebrain. In addition, p73 marks a novel cell population that appears at the choroid-cortical junction or cortical hem before the ...

This is an important paper, which reports relevant information to understand the functional role of the Fe65 proteins. The results clearly demonstrate that the knockout of two members of the Fe65 protein family results in a phenotype similar to that observed in the APP/APLP1/APLP2 triple knockout, thus indicating that the APP-Fe65 complex plays a crucial role during development, as previously suggested by knockout experiments in the worm (Zambrano et al., 2002).. Although the molecular mechanism of the APP-Fe65 machinery is still unclear, two conclusions can be drawn:. 1. The observed phenotype does not depend on misexpression or mislocalization or altered processing of APP induced by the absence of two Fe65s (the marginal decrease of Aβ42 seems to appear only in male mice and no difference between males and females in the brain phenotype is reported).. 2. While the APP knockout phenotype was observed only in the triple knockout (Herms et al., 2004), Fe65L2 alone is unable to compensate for the ...
The search for truly rich and delicious eggs has been quite a little journey. It began well over a year ago, and since then I have searched grocery stores, farmers markets, roadside signs, and private farms. And while I did find some amazing eggs, nothing sparked the A-ha, Eureka, Ive Found it! moment. The eggs that have come the closest are from two local farms, Tomatero Farm in Watsonville, CA and Soul Food Farm in Vacaville, CA. Both farms feature their extremely good eggs in some of the highest end, sustainability-focused restaurants such as Nopa, Chez Panisse, Coi, and Frances. Yet still, something was lacking. The richest orange-yolk shades continued to elude me. And the prices (usually around $7/dozen) were seriously straining my struggling writer / wine-slinger budget. So whats a bona-fide egg fanatic to do? Crazy as it sounds, we decided to go straight to the source. Well, actually, we brought the source to us. ...

Fukuyama congenital muscular dystrophy is an inherited condition that predominantly affects the muscles, brain, and eyes. Congenital muscular dystrophies are a group of genetic conditions that cause muscle weakness and wasting (atrophy) beginning very early in life.. Fukuyama congenital muscular dystrophy affects the skeletal muscles, which are muscles the body uses for movement. The first signs of the disorder appear in early infancy and include a weak cry, poor feeding, and weak muscle tone (hypotonia). Weakness of the facial muscles often leads to a distinctive facial appearance including droopy eyelids (ptosis) and an open mouth. In childhood, muscle weakness and joint deformities (contractures) restrict movement and interfere with the development of motor skills such as sitting, standing, and walking.. Fukuyama congenital muscular dystrophy also impairs brain development. People with this condition have a brain abnormality called cobblestone lissencephaly, in which the surface of the brain ...
Bilateral frontoparietal polymicrogyria (BFPP) is a genetic disorder with autosomal recessive inheritance that causes a cortical malformation. Our brain has folds in the cortex to increase surface area called gyri and patients with polymicrogyri have an increase number of folds and smaller folds than usual. Polymicrogyria is defined as a cerebral malformation of cortical development in which the normal gyral pattern of the surface of the brain is replaced by an excessive number of small, fused gyri separated by shallow sulci and abnormal cortical lamination. From ongoing research, mutation in GPR56, a member of the adhesion G protein-coupled receptor (GPCR) family, results in BFPP. These mutations are located in different regions of the protein without any evidence of a relationship between the position of the mutation and phenotypic severity. It is also found that GPR56 plays a role in cortical pattering. The GPR56 is grouped in the B family of GPCRs. This GPCR group have long N termini ...

We have embryonic cells in our eyes, but theyre not embryonic stem or pluripotent cells. Theyre restricted to making a few cell types, Dr. Temple said as she sketched cells, something that developmental biology lends itself to and that she does when talking about her work.. The researchers obtained human RPEs from eye banks that harvest corneas and then discard whats left. In a body, RPE cells are quiescent, but in culture they divide like crazy, forming coatings of cobblestone-like cells festooned with RPE markers.. To show that an RPE cell could be a stem cell, the researchers gently removed one at a time and transferred it to its own dish, giving it space to divide. This would reveal the defining characteristic of a stem cell: the ability to self-renew, to copy itself. (If all a stem cell could do was turn into any cell type, as theyre often defined, the culture would soon poop out. I see this oversimplification in news releases and media reports on a near-daily basis.). Most of the ...
In the present study, we examined the consequences of FE65 and FE65L1 deficiencies on mammalian brain development in mice. Until now, our understanding of the function of the FE65 family in vivo was limited to its role at the C. elegans neuromuscular junction (Zambrano et al, 2002; Bimonte et al, 2004). We report that the FE65 and FE65L1 proteins are required for integrity of the pial basement membrane, neuronal positioning and the establishment of normal axonal projections during cortical development. Furthermore, the phenotypes of the FE65 and FE65L1 double knockout share remarkable similarities with that reported for mutant mice lacking FE65‐binding partners, the three members of the APP gene family, that is APP, APLP1 and APLP2 (Herms et al, 2004), and the Ena/Vasp protein family (Lanier et al, 1999).. Molecules implicated in neuronal migration such as those necessary for locomotion, nucleokinesis and adhesion of migrating neurons along radial glia contribute to cortical development (Marin ...

Endothelial cells plated on two-dimensional (2-D) substrata proliferate until they form a tightly apposed confluent monolayer of quiescent cells that display a typical cobblestone morphology. When added to proliferating cultures TGF beta-1 (transforming growth factor beta-1) inhibited cell growth and caused marked morphological changes, with the cells becoming enlarged and ragged. These effects were dose-dependent and reversible. TGF beta-1 also reduced the cloning efficiency and colony size of these cells, indicating that TGF beta-1 is cytotoxic and cytostatic for endothelial cells. By contrast, TGF beta-1 added to quiescent cobblestone cultures did not affect cell morphology or cell numbers. In the presence of 20% serum, the level of total protein synthesis per cell was significantly increased by TGF beta-1 in a dose-dependent manner when the cells were cultured on a 2-D substratum, regardless of whether the cells were proliferating or cobblestone quiescent. The level of plasminogen ...

I mentioned in another thread that I dont think a component used by a pro in a race implies that the component is good enough. If say a carbon frame is used in Paris Roubaix, Im pretty sure that thats a brand new frame and it probably wont be used again after the race. Cracks can develop during the course of the race, but not grow over that relatively short period of time and so nothing goes wrong on TV. For stage races, the mechanics most likely thoroughly check each bike and replace where they suspect there might be issues. Contrast with normal consumers who usually ride a frame for at least a couple of years: theyre going to continue using that frame after riding on the same cobblestones, giving any cracks formed the chance to develop and result in the component ultimately becoming unusable ...

When we started working on the landscaping for our cottage in the woods, we were unsure of how to handle the hill that joined the side of the house with our country lane.

They are the Alberta government. Its flu season here in Alberta.. Last year we had a dismal 25% of the population take the flu shot. When the government saw that people were not initially lining up like obedient little children to get a flu shot, they put out the word that there was a very limited amount of vaccine available. People got panicky, and even though they had to pay out of pocket, often stood in line for hours to get the vaccination.

From our preliminary observation, it appears that GE cavitations are an aspect of more complex conditions associated with severe cerebral structural derangement. The awareness of this rare developmental abnormality involving the GE region may have implications in better understanding of the complex malformations caused by defective cellular proliferation and migration, such as lissencephalies. The fact that the lesions were bilateral and symmetric with an inverted regular open C shape, an epithelium-like lining, regular margins, and no apparent signs of hemorrhage (including the 2 cases with T1-weighted images) suggests a malformative rather than necrotic-clastic origin. Familial recurrence in 2 cases and the presence of frontal band heterotopias in 1 case further support such a hypothesis. Although the data are not extensive enough to conclude a statistical significance, the available ADC values (cases 1 and 4), albeit showing a slight trend toward mild reduction (0.85 SD, 0.09 m2/s), ...
My lab is interested in several aspects of the development of the cerebral cortex. We are interested in how the different levels of organization in the cortex, from global to cellular and synaptic organization and from neural to vascular patterning, arise during normal development and how they may be affected in and contribute to brain neural and vascular diseases. To investigate how the exquisite layer organization of the cortex arises, we focus on the question of how the generation and migration of neurons and glia are regulated. We employ mouse genetics approaches and use tissue specific gene knockout technology to answer this question. Among the genes of interest to us is a gene involved in G protein coupled receptor (GPCR) signaling. We have found that mutation in this gene, ric-8a, which encodes a guanine nucleotide exchange factor (GEF) for heterotrimeric G proteins, results in cobblestone lissencephaly-like malformation in the cerebral cortex as well as lobule formation defects in the ...

In any case, we had to stop and ask what would we do if we ever did get there? Preventing the G8 from meeting would never, alone, create the world we wanted. After Genoa, our direct action summit blockade tactics, which just two years before had shut down Seattle, could never happen again in the same way. The next step if we followed that path - really a cul de sac - which they want us to take was to declare all out war in a military battle we could never win. But as the blood dried on the cobblestones and white walls of the raided Diaz school, we realized that the struggle needed, once again, to be on our terms, not theirs. We needed to ...
In reviewing Courtneys analysis in preparation for writing this post, it occurred to me that there is a fourth type of information. Imagine, for example, that my players have entered a room. It would be trivial of me to mention that the cobblestone floors have cracks in a few of the stones. I could mention to the players that the room smells so bad they can taste the pungent air on their tongues. Its not vital for me to do so, since the smell does not affect the game, but it does help the players to imagine their environment, which is fun, so why not. It is crucial that I tell the players there are two exits on the north wall, and that theres a large pile of stones in the corner.. 4. Hidden information.. I should probably not tell the players that theres a pile of gold under the stones. If they want to learn about that, then theyre going to need to do some work. Like maybe digging through the pile of stones.. There are two types of hidden information. The kind which can be modeled at the ...
Spring. It should have meant boat launches on the river, tulips opening in Richters Park, the brick townhouse facades and red cobblestones of Laum Street washed clean and smooth. The air should have been filled with voices and flowers and the far-off scent of rain.. But for the last three years, since the soldiers came, spring in the Reich had meant something else.. I saved you a place, Hermine said. She had been an acquaintance of mine before the revolution: now, when it was safest to surround oneself with patriots and zealots, she was my closest friend. Right below the scaffold. Theyre sure to see you there.. I swallowed past the lump in my throat and followed her though the crowd, gripping her hand when the press became too tight. In this crowd of red and white and gold, we could all-too-easily be separated.. We heard that you were raided, she said as we parted a group of tricolor-wielding schoolchildren. There was a sticky trace of gloating in her voice; she was reassured by the ...
Neil has posted here several times about the Northern Lights, and each time he does, I am reminded of the fact that I have never seen them. This bothers me. Seeing the Northern Lights, in fact photographing them, has long been a life list goal of mine, and the fact Ive never seen anything other than pictures bothers me. Well, pictures is what I have, so for now I have to stick to them. As you probably know, to see the Northern Lights, you have to go North. Easy enough, right. But where? Well, Canada is a good start. But another place, where you can get not just a wonderful full of the lights, but also have a wonderful travel experience, is Finland. Finland has long long been on my list of MUST-VISIT countries. No question about it. Ive wanted to walk the cobblestone roads of Helsinki and sip aquavit there (not to mention check out the lovely Finnish women) for much of my life. And as I say, now I have another reason to go. Here, see what I mean. Check out this series of amazing photos of the ...

What the heck does a minimalist fashion and lifestyle blog have to do with science? Thats what youll be wondering quite soon, which is completely understandable as it was the question that was repeatedly popping up over and over again while posing for the picture above in the lobby of one of the worlds largest PR firms for a supremely over-my-level-of-comprehension conference event for ViaCord. But as with most things judged based on ignorance with just a smidgin of self-absorption, my mind was blown that there was a whole industry I knew nothing about that was saving as many lives as stilettos were tripping up not so effortless fashionistas strolling on cobblestone streets. Is it that we all have our heads to far up our you know whats, or is it more than that? When I mused about my minimalist number (a number thats so much less embarrassing for people to proclaim than the other number, cough cough) I posed a question to you all: what would life loom like if we werent spending 70% of our ...
