Impact of CT and MR on the Diagnostic Evaluation of Neurologic and Neurosurgical Diseases

1989

Today CT and MR are considered to be the most important and most reliable methods for the diagnosis of brain tumors. The sensitivity of these modalities in the detection of intracranial tumors approaches 100%. The extraordinary value of both methods is based not only on this high detection rate but also on their ability to localize tumors in relation to vital centers, assess their mass effect, and establish the tissue type of the lesion (= specificity).

Oral findings in Midline Syndrome: a case report and literature review

2010

We describe a female patient with a midline syndrome. The patient presents agenesis of the corpus callosum, encephalocele, iris coloboma, hypertelorism, submucosal cleft palate and dental anomalies. Despite being very characteristic, her phenotypical traits do not coincide exactly with those reported to date in the literature. The karyotype and the molecular cytogenetic study do not show mutations. We identify the presence of dental anomalies in the mother and other family members, not being identified MSX1 and PAX9 mutations that could the related with their etiology. Despite the fact that dental agenesis has been related to a large number of other malformation syndromes and congenital con…

Impaired border zone formation and adverse remodeling after reperfused myocardial infarction in cannabinoid CB2 receptor deficient mice.

2014

Abstract Aims Reperfusion of myocardial infarction is associated with inflammatory reaction and subsequent myocardial remodeling with a rapid scar formation in mice. The cannabinoid receptor CB2 has been associated with cardioprotection and regulation of macrophage function. We investigated its role in remodeling of reperfused infarction. Main methods One hour LAD-occlusion was followed by reperfusion over 6 h and 1, 3 and 7 days in wild-type C57/BL6J (WT) and CB2 receptor-deficient (Cnr2 −/− ) mice (n = 8/group). Hearts were processed for functional, morphological and mRNA/protein analysis, and tissue concentration of endocannabinoids was determined using liquid chromatography-multiple rea…

CYTOGENETICS OF THE AMPHIPOD JASSA MARMORATA (COROPHIOIDEA: ISCHYROCERIDAE): KARYOTYPE MORPHOLOGY, CHROMOSOME BANDING, FLUORESCENTIN SITUHYBRIDIZATIO…

2000

Abstract Developing embryos proved to be a suitable source of cells for advanced cytological investigations on Amphipods. Conventional karyotyping, Ag- and fluorochrome-staining, C-banding, endonuclease digestion, fluorescent in situ hybridization (FISH) and nuclear DNA flow cytometric assay were tested in the Ischyroceridae Jassa marmorata. The karyotype consists of 6 chromosome pairs of which 5 are metacentric and 1 subtelocentric. The rDNA/FISH revealed that major ribosomal cistrons are located on the telomeric regions in the short arm of pair 6. A marked size variation of hybridization signals was observed. Silver and fluorochrome staining enhanced no chromosome regions. Constitutive he…

The phototransduction cascade in the isolated chick pineal gland revisited.

2003

It is well established that the isolated chick pineal gland is directly light sensitive and that melatonin synthesis of the gland can be inhibited by exposing the gland to light during scotophase. Since not all the steps of the phototransduction cascade have been clarified to the same extent as in the retina, we have treated isolated chick pineal glands with 90 min of light during scotophase and with drugs that affect key-components of vertebrate phototransduction, i.e., cyclic guanosine monophosphate (cGMP) phosphodiesterase 6 (PDE6), cGMP levels and cGMP-gated calcium channels. The endpoint measured was the activity of the rate-limiting enzyme of melatonin synthesis, arylalkylamine N-acet…

Genetic variation at the perilipin (PLIN) locus is associated with obesity-related phenotypes in White women

2004

Perilipin coats intracellular lipid droplets and modulates adipocyte lipolysis. We have evaluated the association between several polymorphisms at the perilipin (PLIN) locus (PLIN1 : 6209T > C, PLIN4 : 11482G > A, PLIN5 : 13041A > G, and PLIN6 : 14995A > T) with obesity-related phenotypes in 1589 White subjects randomly selected from a general Spanish population. In women (n = 801), the less common alleles of PLIN1 and PLIN4, in strong linkage disequilibrium (D' : 0.96), were significantly associated with lower body mass index. Carriers of the allele 2 (6209C) at the PLIN1 locus weighed significantly less (-2.2 kg; p = 0.007) than women homozygotes for the wild-type genotype. The same was t…

Six new loci associated with blood low-density lipoprotein cholesterol, high-density lipoprotein cholesterol or triglycerides in humans

2008

Blood concentrations of lipoproteins and lipids are heritable1 risk factors for cardiovascular disease2,3. Using genome-wide association data from three studies (n = 8,816 that included 2,758 individuals from the Diabetes Genetics Initiative specific to the current paper as well as 1,874 individuals from the FUSION study of type 2 diabetes and 4,184 individuals from the SardiNIA study of aging-associated variables reported in a companion paper in this issue4) and targeted replication association analyses in up to 18,554 independent participants, we show that common SNPs at 18 loci are reproducibly associated with concentrations of low-density lipoprotein (LDL) cholesterol, high-density lipo…

Islet beta-cell apoptosis triggered in vivo by interleukin-1beta is not related to the inducible nitric oxide synthase pathway: evidence for mitochon…

2003

IL-1beta is recognized as an effector cytokine contributing to islet beta-cell destruction during diabetes. We have previously shown in vitro that IL-1beta induces nitric oxide (NO) and beta-cell damage. Here, we show that IL-1beta administration in vivo to Wistar rats transiently increases manganese superoxide dismutase activity, whereas inducible NO synthase is not detected, and the levels of nitrate+nitrate do not change. Moreover, a significant decrease of mitochondrial aconitase, leading to a rise of hydroperoxides, and islet beta-cell apoptosis, involving caspase-3 and -8, is observed. Analysis of adhesion molecules in beta-cells showed that intercellular adhesion molecule-1 is highly…
