Humoral immunity and retrobulbar fibroblasts in endocrine ophthalmopathy

1992

The exact role of retrobulbar fibroblasts in the immunopathogenesis of endocrine ophthalmopathy still remains to be elucidated. To evaluate the in vitro influence of humoral immunity on retrobulbar fibroblasts, the effects of immunoglobulin G as well as of the sera of 50 euthyroid patients with endocrine ophthalmopathy and 30 controls on both porcine and human (patients' and controls') retrobulbar fibroblasts were measured by means of several assays: a colorimetric test involving a heterocyclic chemical, a tetrazolium bromide, was applied to quantify the activity of mitochondrial dehydrogenases; the incorporation of 3H-thymidine was determined as a sensitive parameter for cell proliferation…

Developmental and content effects in reasoning with causal conditionals.

2002

Abstract Two predictions derived from Markovits and Barrouillet's (2001) developmental model of conditional reasoning were tested in a study in which 72 twelve-year-olds, 80 fifteen-year-olds, and 104 adults received a paper-and-pencil test of conditional reasoning with causal premises (“if cause P then effect Q”). First, we predicted that conditional premises would induce more correct uncertainty responses to the Affirmation of the consequent and Denial of the antecedent forms when the antecedent term is weakly associated to the consequent than when the two are strongly associated and that this effect would decrease with age. Second, uncertainty responding to the Denial of the antecedent f…

Inhibition of Fcγ Receptors in the Plasma of Subjects with Down's Syndrome

1993

Abstract Subjects with Down's syndrome have several immunological abnormalities. We examined the sera of 29 subjects with Down's syndrome for the presence of Fcγ receptor blocking and for the presence of anti-ssDNA antibodies by EA rosette inhibition. Fifty-five percent of Down subjects had levels of inhibition above the upper limit of normality in comparison to 7% of normal controls. The finding that after polyethylene glycol precipitation of selected sera giving high levels of EA rosette inhibition there was a reduction or a disappearance of the EA rosette inhibition could indicate that the blocking factors detected behaved as immune complexes. Since almost all subjects with anti-ssDNA an…

A Validation Study of the Spanish Version of the Hypersexual Behavior Inventory (HBI): Paper-and-Pencil Versus Online Administration.

2019

Hypersexuality is a problematic behavior characterized by the combination of an excessive sexual desire and the pathological inability to control it. This study presents the psychometric properties of the Spanish paper-and-pencil and online versions of the Hypersexual Behavior Inventory (HBI), one of the most popular scales to assess this issue. 2250 participants (1070 men) completed a translated version of the HBI (1450 in paper-and-pencil; 800 online). The EFA yielded three factors that explained 67.53% of total variance for the HBI paper-and-pencil version. This factor structure was confirmed in the HBI online version through CFA. Factorial, structural, scalar and error variance invarian…

Increased accessibility of semantic concepts after (more or less) subtle activation of related concepts: support for the basic tenet of priming resea…

2019

Increasingly remote concepts and behaviors have been primed, which have come under increasing criticism. In this present experiment, we take a step back and try to strengthen the roots of priming research. In this experiment, we systematically varied the activation or priming of a concept in six experiments (

Phonological-Lexical Feedback during Early Abstract Encoding: The Case of Deaf Readers.

2016

In the masked priming technique, physical identity between prime and target enjoys an advantage over nominal identity in nonwords (GEDA-GEDA faster than geda-GEDA). However, nominal identity overrides physical identity in words (e.g., REAL-REAL similar to real-REAL). Here we tested whether the lack of an advantage of the physical identity condition for words was due to top-down feedback from phonological-lexical information. We examined this issue with deaf readers, as their phonological representations are not as fully developed as in hearing readers. Results revealed that physical identity enjoyed a processing advantage over nominal identity not only in nonwords but also in words (GEDA-GE…

Temporal dynamics of hippocampal neurogenesis in chronic neurodegeneration.

2014

Increased neurogenesis has been reported in neurodegenerative disease, but its significance is unclear. In a mouse model of prion disease, Gomez-Nicola et al. detect increased neurogenesis in the dentate gyrus that partially counteracts neuronal loss. Targeting neurogenesis may have therapeutic potential.

Structure, chromosomal localization, and brain expression of human Cx36 gene

1999

Rat connexin-36 (Cx36) is the first gap junction protein shown to be expressed predominantly in neuronal cells of the mammalian central nervous system. As a prerequisite for studies devoted to the investigation of the possible role of this connexin in human neurological diseases, we report the cloning and sequencing of the human Cx36 gene, its chromosomal localization, and its pattern of expression in the human brain analyzed by radioactive in situ hybridization. The determination of the human gene sequence revealed that the coding sequence of Cx36 is highly conserved (98% identity at the protein level with the mouse and rat Cx36 and 80% with the ortholog perch and skate Cx35), and that the…

Animacy matters: ERP evidence for the multi-dimensionality of topic-worthiness in Chinese

2013

Abstract An event-related potential (ERP) study was conducted to investigate how animacy interacts with givenness during topic processing. Both animacy and givenness have been considered as within-discourse factors that contribute to an element׳s potential to form an optimal topic (i.e., topic-worthiness). ERPs were recorded while participants read question–answer pairs, of which the target sentence induced either a continuation or an alternation of a previously introduced topic (i.e., given vs. new). Depending on the context, a potential topic further differed in its animacy from the preceding one (i.e., animate vs. inanimate). The data revealed a robust givenness effect with an N400 reduc…
