Characterization of nodular neuronal heterotopia in children. (1/605)

Neuronal heterotopia are seen in various pathologies and are associated with intractable epilepsy. We examined brain tissue from four children with subcortical or periventricular nodular heterotopia of different aetiologies: one with severe epilepsy following focal brain trauma at 17 weeks gestation, one with hemimegalencephaly and intractable epilepsy, one with focal cortical dysplasia and intractable epilepsy, and one dysmorphic term infant with associated hydrocephalus and polymicrogyria. The connectivity of nodules was investigated using histological and carbocyanine dye (DiI) tracing techniques. DiI crystal placement adjacent to heterotopic nodules revealed numerous DiI-labelled fibres within a 2-3 mm radius of the crystals. Although we observed labelled fibres closely surrounding nodules, the majority did not penetrate them. Placement of DiI crystals within nodules also identified a limited number of projections out of the nodules and in one case there was evidence for connectivity between adjacent nodules. The cellular and neurochemical composition of nodules was also examined using immunohistochemistry for calretinin and neuropeptide Y (NPY), which are normally expressed in GABAergic cortical interneurons. Within heterotopic nodules from all cases, numerous calretinin-positive neurons were identified, along with a few cell bodies and many processes positive for NPY. Calretinin-positive neurons within nodules were less morphologically complex than those in the cortex, which may reflect incomplete differentiation into an inhibitory neuronal phenotype. There were also abnormal clusters of calretinin-positive cells in the overlying cortical plate, indicating that the migratory defect which produces heterotopic nodules also affects development of the cortex itself. Thus, heterotopic nodules consisting of multiple neuronal cell types are associated with malformation in the overlying cortical plate, and have limited connectivity with other brain regions. This abnormal development of connectivity may affect neuronal maturation and consequently the balance of excitation and inhibition in neuronal circuits, leading to their epileptogenic potential.  (+info)

Spatiotemporal pattern of the mouse chondromodulin-I gene expression and its regulatory role in vascular invasion into cartilage during endochondral bone formation. (2/605)

During endochondral bone formation, vascular invasion into cartilage initiates the replacement of cartilage by bone. Chondromodulin-I, a 25 kDa glycoprotein purified from bovine epiphyseal cartilage, was recently identified as a novel endothelial cell growth inhibitor. Here we cloned the mouse chondromodulin-I cDNA from a mouse whole embryo cDNA library. Northern blot analysis revealed that the chondromodulin-I transcripts were expressed in association with the formation of cartilage expressing type II collagen from days 11 to 17 of gestation in mouse embryos, at which time cartilaginous bone rudiments were gradually replaced by bone. Chondromodulin-I mRNA was also detected in the thymus and eyes at a lower level. In situ hybridization revealed significant expression in all cartilaginous tissues in the embryos at days 13.5 and 16 of gestation. However, the expression was completely abolished in the hypertrophic cartilage zone prior to calcification. Upon chondrogenic differentiation of mouse ATDC5 cells in vitro, the expression of chondromodulin-I transcripts was induced concomitantly with the formation of type II collagen-expressing chondrocytes. The expression of the transcripts then declined as type X collagen-expressing hypertrophic chondrocytes appeared in the culture. Purified chondromodulin-I protein inhibited the vascular invasion into cartilage ectopically induced by demineralized bone matrix in nude mice, leading to the suppression of bone formation in vivo. These results suggest that chondromodulin-I is involved in the anti-angiogenic property of cartilage, and that the withdrawal of its expression allows the vascular invasion which triggers the replacement of cartilage by bone during endochondral bone development.  (+info)

Reversion of the differentiated phenotype and maturation block in Sertoli cells in pathological human testis. (3/605)

To study the relationship between abnormal Sertoli cell differentiation and spermatogenic impairment, we examined the expression of Sertoli cell markers normally lost at puberty, cytokeratin 18 (CK18), anti-Mullerian hormone (AMH) and M2A antigen, in three children (aged 1-2 years), 50 adults (aged 19-45 years) with obstructive or non-obstructive azoospermia or oligozoospermia, and six patients (aged 1-18 years) with 5 alpha-reductase deficiency. There was CK18 and/or AMH expression, but never M2A antigen expression, associated with spermatogonial arrest or Sertoli cell-only (SCO) syndrome in infertile men. Loss of M2A antigen suggests the transition of Sertoli cells to an adult phenotype, while CK18 and/or AMH expression may be a manifestation of de-differentiation of Sertoli cells. In 5 alpha-reductase deficiency, there was a sequential loss of CK18, M2A antigen and AMH around puberty, associated with partial spermatogenesis. The persistence of immature Sertoli cells expressing M2A antigen was associated with prepubertal seminiferous cords and SCO syndrome. Therefore, 5 alpha-reductase deficiency may prevent the maturation of Sertoli cells, resulting in impairment of spermatogenesis, and loss of M2A antigen expression coincides with a critical step in the Sertoli cell maturation. High follicle stimulating hormone concentrations due to failure of normal Sertoli cell differentiation indicate a normal development pattern of the hypothalamic-pituitary-gonadal axis.  (+info)

Possible mechanisms by which pro- and prebiotics influence colon carcinogenesis and tumor growth. (4/605)

Oligofructose and inulin, selective fermentable chicory fructans, have been shown to stimulate the growth of bifidobacteria, which are regarded as beneficial strains in the colon. Studies were designed to evaluate inulin (Raftiline) and oligofructose (Raftilose) for their potential inhibitory properties against the development of colonic aberrant crypt foci (ACF) in rats. ACF are putative preneoplastic lesions from which adenomas and carcinomas may develop in the colon. The results of this study indicate that dietary administration of oligofructose and inulin inhibits the development of ACF in the colon, suggesting the potential colon tumor inhibitory properties of chicory fructans. The degree of ACF inhibition was more pronounced in animals given inulin than in those fed oligofructose. Because these prebiotics selectively stimulate the growth of bifidobacteria, ornithine decarboxylase (ODC) activities, ras-p21 ontoprotein expressions and tumor inhibitory activity of lyophilized cultures of Bifidobacterium longum against chemically induced colon and mammary carcinogenesis and against colonic tumor cell proliferation were examined. Dietary administration of lyophilized cultures of B. longum strongly suppressed colon and mammary tumor development and tumor burden. Inhibition of colon carcinogenesis was associated with a decrease in colonic mucosal cell proliferation and activities of colonic mucosal and tumor ornithine decarboxylase and ras-p21. Human clinical trials are likely to broaden our insight into the importance of the pre- and probiotics in health and disease.  (+info)

The effect of synbiotics on colon carcinogenesis in rats. (5/605)

Evidence indicates that consumption of probiotic microorganisms such as bifidobacteria reduces the risk of colon cancer in animal models. Feeding certain fructans such as oligofructose and inulin, which are thought to selectively increase the growth of intestinal bifidobacteria (i.e., a prebiotic effect), also has been shown to reduce colon cancer risk. The objective of our study was twofold, i. e., to determine whether the combination of bifidobacteria and oligofructose would have an additive effect (i.e., synbiotic) in reducing colon cancer risk in rats, and to determine whether other oligosaccharides would also be effective as part of a synbiotic combination. The development of colonic preneoplastic lesions (aberrant crypts) was used as an index of colon cancer risk. In one series of experiments, rats were given the carcinogen 1, 2-dimethylhydrazine (DMH) and administered one of the following treatments: skim milk (control), bifidobacteria (bifido), oligofructose (OF) or bifido + OF. Neither bifido nor OF alone significantly reduced aberrant crypt number. Bifido + OF reduced aberrant crypt number in five of six experiments, although the reduction was significant in only one. However, a paired comparison of the six experiments indicated a significant overall reduction in aberrant crypts by bifido + OF (P = 0.039). Soybean oligosaccharide (SBO) and wheat bran oligosaccharide (WBO) were also fed in combination with bifidobacteria. In two other experiments, SBO did not alter the number of aberrant crypts compared with the control, whereas WBO reduced aberrant crypt number in one experiment but not in another. Of OF, SBO and WBO, only SBO reduced the colonic mucosa proliferation compared with the control. These results suggest that the combination of bifidobacteria and oligofructose reduces colon cancer risk in carcinogen-treated rats, but the effect of other oligosaccharides is uncertain.  (+info)

Adult-onset neurologic dysfunction associated with cortical malformations. (6/605)

BACKGROUND AND PURPOSE: Malformations of cerebral cortical development are common anomalies of the brain, typically causing developmental delay or seizures that are classically thought to begin in childhood. We present clinical and MR imaging data of 16 patients with cortical malformations in whom evidence of neurologic dysfunction was first noted in adulthood, and attempt to determine whether these malformations had any differentiating features from those presenting in childhood. METHODS: Imaging studies and clinical records of 16 patients with adult-onset neurologic dysfunction were reviewed retrospectively. The patients ranged in age from 17 to 64 years (mean age, 35 years) at the time of imaging. Imaging findings were correlated with seizure history. RESULTS: Fourteen patients had subependymal heterotopia (seven women, seven men), and two patients had closed-lip schizencephalies. Eleven patients had epilepsy, with age of onset ranging from 14 to 45 years (mean age, 22 years); four of them were successfully controlled by medication. The remaining five patients had no seizure disorder. All patients, except one, had normal intelligence. The bilaterality or multiplicity of location of heterotopias was not associated with the presence or absence of seizures, seizure frequency, or electroencephalographic results. CONCLUSION: Subependymal heterotopia and small closed-lip schizencephaly may have minor clinical manifestations that are not evident until adulthood, or may, occasionally, never cause neurologic signs or symptoms whatsoever.  (+info)

Pax6 induces ectopic eyes in a vertebrate. (7/605)

We report here that misexpression of the transcription factor Pax6 in the vertebrate Xenopus laevis leads to the formation of differentiated ectopic eyes. Multiple molecular markers indicated the presence of mature lens fiber cells, ganglion cells, Muller cells, photoreceptors and retinal pigment epithelial cells in a spatial arrangement similar to that of endogenous eyes. Lineage tracing experiments showed that lens, retina and retinal pigment epithelium arose as a consequence of the cell-autonomous function of Pax6. These experiments also reveal that the cell autonomous activity of misexpressed Pax6 causes the ectopic expression of a number of genes including Rx, Otx2, Six3 and endogenous Pax6, each of which has been implicated in eye development. The formation of ectopic and endogenous eyes could be suppressed by coexpression of a dominant-negative form of Pax6. These data show that in vertebrates, as in the invertebrate Drosophila melanogaster, Pax6 is both necessary and sufficient to trigger the cascade of events required for eye formation.  (+info)

Cerebral amyloid induces aberrant axonal sprouting and ectopic terminal formation in amyloid precursor protein transgenic mice. (8/605)

A characteristic feature of Alzheimer's disease (AD) is the formation of amyloid plaques in the brain. Although this hallmark pathology has been well described, the biological effects of plaques are poorly understood. To study the effect of amyloid plaques on axons and neuronal connectivity, we have examined the axonal projections from the entorhinal cortex in aged amyloid precursor protein (APP) transgenic mice that exhibit cerebral amyloid deposition in plaques and vessels (APP23 mice). Here we report that entorhinal axons form dystrophic boutons around amyloid plaques in the entorhinal termination zone of the hippocampus. More importantly, entorhinal boutons were found associated with amyloid in ectopic locations within the hippocampus, the thalamus, white matter tracts, as well as surrounding vascular amyloid. Many of these ectopic entorhinal boutons were immunopositive for the growth-associated protein GAP-43 and showed light and electron microscopic characteristics of axonal terminals. Our findings suggest that (1) cerebral amyloid deposition has neurotropic effects and is the main cause of aberrant sprouting in AD brain; (2) the magnitude and significance of sprouting in AD have been underestimated; and (3) cerebral amyloid leads to the disruption of neuronal connectivity which, in turn, may significantly contribute to AD dementia.  (+info)

Development of SCN in tissues other than the pancreas has been never reported. Here we present the first reported case of SCN in an intrapancreatic accessory spleen (IPAS). A 54-year-old female patient with von Hippel-Lindau (VHL) syndrome was found to have pancreatic tail mass. Pathologically the 25-mm solid mass was an IPAS showing proliferation of clear cuboidal tumor cells without atypia, forming numerous small cysts. The tumor cells were rich in cytoplasmic glycogen and distributed in the splenic tissue almost diffusely. Immunohistochemically, tumor cells were positive for cytokeratins, MUC6, and neuron-specific enolase, and negative ...
Nasal glial heterotopia refers to congenital malformations of displaced normal, mature glial tissue, which are no longer in continuity with an intracranial component. This is distinctly different from an encephalocele, which is a herniation of brain tissue and/or leptomeninges, that develops through a defect in the skull, where there is a continuity with the cranial cavity. While nasal glial heterotopia (NGH) is the preferred term, synonyms have included nasal glioma. However, this term is to be discouraged, as it implies a neoplasm or tumor, which it is not. By definition, nasal glial heterotopia is a specific type of choristoma. It is not a teratoma, however, which is a neoplasm comprising all three germ cell layers (ectoderm, endoderm, mesoderm). As a congenital malformation or ectopia, it is distinctly different from the trauma or iatrogenic development of an encephalocele. Patients come to clinical attention early in life (usually at birth or within the first few months), with a firm ...
We report a rare case of nasal glial heterotopia in an adult. After the surgery, frontal lobe cerebral hemorrhage developed. A 58-year-old man had unilateral nasal obstruction that progressed for one year. He had been treated for hypertension, chronic heart failure, and cerebral infarction with aspirin and warfarin. A computed tomography scan showed that the tumor occupied the right nasal cavity and the sinuses with small defect in the cribriform plate. The tumor was removed totally with endoscopy. After the operation, the patient developed convulsions and frontal lobe cerebral hemorrhage. The hemorrhage site was located near a defect in the cribriform plate. Nasal glial heterotopia is a rare developmental abnormality, particularly rare in adult. Only few cases were reported. We could not find any report of adult nasal glial heterotopias that developed cerebral hemorrhage as a complication of the surgery.
The development of pancreatic tissue outside the confines of the main gland, without anatomic or vascular connections between them, is a congenital abnormality referred to as heterotopic pancreas. A heterotopic pancreas in the gastrointestinal tract is usually discovered incidentally and the risk of its malignant transformation is extremely low. In this study, we describe the first case of endoepithelial carcinoma arising in a gastric heterotopic pancreas of a 56-year old woman in Greece. She presented with epigastric pain, periodic nausea and vomiting. Esophagogastroduodenoscopy revealed an ulcerated lesion in the gastric antrum, biopsies of which showed intense epithelial dysplasia with incipient malignant degeneration. The pathology report of the distal gastrectomy specimen demonstrated a 2 cm in diameter ulcerative mass in the gastric antrum. Microscopically, an endoepithelial (in situ) carcinoma of the gastric antrum was determined, which in places turned into an microinvasive endomucosal

Introduction: Heterotopias, which are also referred to as choristomas and ectopias, are characterized by the presence of normal-appearing tissue in an anatomical location in which they are normally not found. Clinicopathological aspects of Heterotopias of the Head and neck from our institute is presented in this study. Materials and methods: This study is conducted in a tertiary care center for Head and neck diseases. The Heterotopic lesions occurring in head and neck reported between 2008 and 2016 were included in the study. 24 cases of Head and neck heterotopias were identified. Clinical findings, radiological, cytological and histopathological aspects were analysed. Results: Heterotopias constituted 0.17% of all head and neck lesions. A total of 24 cases of heterotopias were analysed. Thyroid heterotopias constituted majority, 13 cases (54.16%). There were 5 cases of Glial heterotopias (20.83%), 3 Salivary gland heterotopias (12.5%), 2 gastric heterotopias (8.33%) (one single tissue type and ...
Pancreatic heterotopia (PH) is defined as ectopic pancreatic tissue outside the normal pancreas and its vasculature and duct system. Most frequently, PH is detected incidentally by histopathological examination. The aim of the present study was to analyze a large single-center series of duodenal PH with respect to the clinical presentation. A prospective pancreatic database was retrospectively analyzed for cases of PH of the duodenum. All pancreatic and duodenal resections performed between January 2000 and October 2015 were included and screened for histopathologically proven duodenal PH. PH was classified according to Heinrichs classification (Type I acini, ducts, and islet cells; Type II acini and ducts; Type III only ducts). A total of 1274 pancreatic and duodenal resections were performed within the study period, and 67 cases of PH (5.3%) were identified. The respective patients were predominantly male (72%) and either underwent pancreatoduodenectomy (n = 60); a limited pancreas resection with

In a retrospective study, 37 male and 19 female inbred laboratory mice, from 1 to 36 weeks of age, were diagnosed with lipomatous hamartomas or choristomas from nearly 10,000 mice examined at necropsy over a 24-month period. Hamartomas and choristomas were found to be rare, noninherited tumor-like conditions that occurred spontaneously in 18 inbred strains of mice with a predominance of the conditions in the C3H/HeJ and C57BL/6J strains. Prevalence between strains ranged from 0.6 to 6.2 cases per hundred thousand mice. The 56 cases studied had soft, raised masses that arose on the dorsal midline, primarily above the sutures of the skull. The lesions were prominent on gross examination due to abnormally long hair, change in direction of the hairs, and a change in hair color compared to the normal pelage. Microscopically, the masses consisted of normal adipose tissue in the reticular dermis and subcutis that sometimes extended through the cranial sutures, entering the brain, or expanding
ear a bony deficit with consequent herniation of brain tissue into the middle ear should be ruled out [53]. Three cases of heterotopic brain tissue in the middle ear associated with cholesteatoma have been reported [62]. It is possible that in all three, brain herniation occurred as a result of inflammatory damage to the tegmen tympani. Spontaneous herniations of brain (encephaloceles) may occur into the middle ear through a congenital deficiency of the tegmen or other sites [47]..

The previously reported prevalence of gastric heterotopia in the cervical esophagus, also termed inlet patch (IP), varies substantially, ranging from 0.18 to 14%. Regarding cases with adenocarcinoma within IP, some experts recommend to routinely obtain biopsies from IP for histopathology. Another concern is the reported relation to Barretts esophagus. The objectives of the study were to prospectively determine the prevalence of IP and of preneoplasia within IP, and to investigate the association between IP and Barretts esophagus. 372 consecutive patients undergoing esophagogastroduodenoscopy were carefully searched for the presence of IP. Biopsies for histopathology were targeted to the IP, columnar metaplasia of the lower esophagus, gastric corpus and antrum. Different definitions of Barretts esophagus were tested for an association with IP. At least one IP was endoscopically identified in 53 patients (14.5%). Histopathology, performed in 46 patients, confirmed columnar epithelium in 87% of cases,

Aberrations of p53 occur in most, if not all, human cancers. In breast cancer, p53 mutation is the most common genetic defect related to a single gene. Immortalized human mammary epithelial cells resemble the earliest forms of aberrant breast tissue growth but do not express many malignancy-associated phenotypes. We created a model of human mammary epithelial tumorigenesis by infecting hTERT-HME1 immortalized human mammary epithelial cells expressing wild-type p53 with four different mutant p53 constructs to determine the role of p53 mutation on the evolution of tumor phenotypes. We demonstrate that different mutant/wild-type p53 heterozygous models generate loss of function, dominant negative activity, and a spectrum of gain of function activities that induce varying degrees of invasive potential. We suggest that this model can be used to elucidate changes that occur in early stages of human mammary epithelial tumorigenesis. These changes may constitute novel biomarkers or reveal novel ...
Dickkopf-1 (Dkk1), which inhibits canonical Wnt/β-catenin signaling by binding to the Wnt coreceptors LDL-related protein 5 (LRP5) and LRP6 through its carboxy-terminal cysteine-rich domain (C1), induces heart and head cell fates in Xenopus laevis embryos more potently than do other Wnt antagonists, suggesting that it may have additional roles. Korol et al. report that the amino-terminal cysteine-rich domain (N1) of Dkk1 is required for its maximal induction of cell fate and functions independently of canonical Wnt signaling. Overexpression of Dkk1 alone induces ectopic cement gland, the most anterior structure in the embryo, and heart tissues in embryos, and co-overexpression of Dkk1 with a truncated receptor that inhibits bone morphogenetic protein signaling induces the formation of a secondary body axis. When tested in these overexpression assays, the N1 domain did not induce ectopic tissues, the C1 domain induced some ectopic tissues, and N1 + C1 induced more ectopic tissues than C1 alone ...

We recently identified Eml1, a protein binding to microtubules, mutated in subcortical heterotopia (SH) featuring many mis-positioned neurons in the white matter (Kielar* Phan Dinh Tuy*, in press). Eml1s role in cortical development was never previously studied and little is known about the biochemical pathways in which it acts. We study Eml1 in mouse neuronal progenitors and post-mitotic neurons and question novel mechanisms leading to SH (Project 1). Defects in the CNTNAP2 gene, coding for the adhesion protein Caspr2, have also recently been characterized in a wide and expanding spectrum of neurodevelopmental disorders, including cortical dysplasia-focal epilepsy syndrome (CDFE)5 and autism6. Caspr2 is well-known for its roles in axo-glial contacts at the Nodes of Ranvier7, but its neurodevelopmental functions are little-studied. We question molecular and cellular functions of Caspr2 during neuronal migration and synaptogenesis, and the consequences of CNTNAP2 variants identified in patients ...

Software Packages for Holonomic Gradient Method. The numerical evaluation of the normalizing constant for a given statistical distribution is a fundamental problem in statistics. For example, the normalizing constant of the Gaussian distribution is expressed in terms of a rational expression of a parameter of the distribution named as the standard deviation. However, normalizing constants of many interesting stasistical distributions do not have such closed expressions. The holonomic gradient method, HGM in short, is a general method to evaluate normalizing constant numerically for several parameters in the framework of Zeilbergers holonomic systems approach. In fact, broad classes of normalizing constants are holonomic functions with respect to parameters. Then, such normalizing constants satisfy holonomic systems of linear partial differential equations. The HGM consists of three steps for a given normalizing constant. (1) Find a holonomic system satisfied by the normalizing constant. We may use
Polymicrogyria (PMG) and periventricular nodular heterotopia (PNH) are two developmental brain malformations that have been described independently in multiple syndromes. Clinically, they present with epilepsy and developmental handicaps in both children and adults. Here we describe their occurrence together as the two major findings in a group of at least three cortical malformation syndromes. We identified 30 patients as having both PNH and PMG on brain imaging, reviewed clinical data and brain imaging studies (or neuropathology summary) for all, and performed mutation analysis of FLNA in nine patients. The group was divided into three subtypes based on brain imaging findings. The frontal-perisylvian PNH-PMG subtype included eight patients (seven males and one female) between 2 days and 10 years of age. It was characterized by PNH lining the lateral body and frontal horns of the lateral ventricles and by PMG most severe in the posterior frontal and perisylvian areas, occasionally with ...

CONTEXT: Acute pancreatitis in ectopic pancreatic tissue is an uncommon cause of acute abdominal pain and can be difficult to diagnose on imaging. Our aim is to raise awareness and aid in the diagnosis of this entity by highlighting helpful dynamic contrast-enhanced MRI imaging findings. CASE REPORT: We report a 51-year-old man with acute onset epigastric pain presented to ER. With the presence of elevated serum lipase, the clinical diagnosis of acute pancreatitis was made. Contrast enhanced CT demonstrated normal pancreas and a focal mass at the duodenojejunal flexure, mimicked a neoplasm. Subsequent dynamic contrast enhanced MR images demonstrated enhancement pattern of the lesion similar to the native pancreatic tissue enhancement, a finding raised the possibility of acute pancreatitis in ectopic pancreatic tissue, but tumor was not excluded. Finally, patient undergone surgical bowel resection including the suspected mass that was proved as an ectopic pancreatic tissue on microscopic examination.
The butterfly effect is defined as the sensitive dependence on initial conditions, where a small change at one place in a deterministic nonlinear system can result in large differences to a later state. In medicine, the identification of a rare disease or a genetic mutation may provide insights that spread well beyond the initial discovery.. And in genetics, scientists are learning just how widespread the effects are for mutations in one gene: filaminA (FLNA).. FLNA is a common cause of periventricular nodular heterotopia (PVNH), a disorder of neuronal migration during brain development. The syndrome was first described by the late Peter Huttenlocher, MD, and the gene was identified by Christopher Walsh, MD, PhD, of Boston Childrens Hospital.. In normal brain development, neurons form in the periventricular region, located around fluid-filled ventricles near the brains center, then migrate outward to form six onion-like layers. In PVNH, some neurons fail to migrate to their proper position ...

OP28 The complement component C3 is expressed by the endometrial ectopic tissue and is involved in the endometriotic lesion formation C. Agostinis 1, G. Zito 1, D. De Santo1, R. Vidergar2, O. Radillo 1, F. Bossi 1, S. Zorzet2, G. Ricci 1, R. Bulla 2 1 Institute for Maternal and Child Health, IRCCS Burlo Garofolo, Trieste, Italy 2 Department of Life Sciences, University of Trieste, Trieste, Italy E-mail address: [email protected] (C. Agostinis). Background: The complement (C) system is one of the major components of humoral innate immunity, acting as the first lines of defence against microbes. The principal roles of C system are the opsonization and lysis of pathogens, but new roles in inflammatory and immunological processes are emerging. It is involved in numerous inflammatory diseases, such as SLE, PNH and endometriosis (EM). Several groups have been demonstrated that the glandular epithelial cells found in endometriotic implants produce and secrete the C component C3. The aim ...
CONCLUSIONS: We report the clinical and mutation spectrum as well as MR imaging for a large cohort of 47 patients with Filamin A associated PVNH including two adult males. Our data are reassuring in regard to psychomotor and cognitive development, which is within normal range for the majority of patients. However, a concerning median diagnostic latency of 17 to 20 years was noted between seizure onset and the genetic diagnosis, intensely delaying appropriate medical surveillance for potentially life threatening cardiovascular complications as well as genetic risk assessment and counseling prior to family planning for this X-linked dominant inherited disorder with high perinatal lethality in hemizygous males. ...
Since the observation that malformed brain structure is associated with intractable forms of epilepsy, there has been a great deal of interest in trying to understand the function of dysplastic neurons. Here we performed experiments to investigate the influence of GABAergic inhibition on hippocampal heterotopic neurons in an animal model of malformation-associated epilepsy, e.g., rats exposed to MAM in utero. Our main findings in these animals include the following: (1) an alteration in the decay kinetics of evoked and spontaneous IPSCs recorded on heterotopic neurons, (2) normal inhibitory responses for heterotopic neurons after exogenous GABA application, (3) an inability to alter IPSC decay kinetics when heterotopic neurons are exposed to GABA transport inhibitors, and (4) a low level of GAT expression in heterotopic cell regions. Together, these results suggest altered inhibitory synaptic function at heterotopic synapses in the MAM model.. Abnormal electrical discharges, the hallmark of ...

Aphanitic Singularity [abstrakt Alisa Andrasek + Netochka Nezvanova All possible branches are real (Borges, J.L. The Garden of Forking Paths) Gardens were always optimistic reflections of the world, the liminal spaces between the known and unknown, matter and aether. Foucault describes gardens as the oldest form of heterotopias, a microcosm of species, the smallest parcel of the world in its totality: The heterotopia is capable of juxtaposing in a single real place several spaces, several sites that are in themselves incompatible ... the oldest example of these heterotopias that take the form of contradictory sites is the garden. Shifting away from millennia old, rigid and static instrumentalities of control on the one side and fictional representational effects on the other, this paper discusses genware, a computational system employing dynamically relational assemblages for analysis, synthesis and cataloguing of regional folkloric and cultural artifacts phenotypes into a library of ...
Most of us are born with two ureters, one to drain the urine from each kidney into the bladder. But some babies are born with 2 ureters that drain a single kidney. In these cases, one ureter drains the upper part of the kidney and the second ureter drains the lower part of the kidney. As long as they both enter the bladder, this extra ureter is usually not a problem.
