Children evoke similar affective and instructional responses from their teachers and mothers

2015

In the present study, we examined the extent to which the responses of teachers and mothers toward a particular child are similar in respect to their instructional support and affect, and whether child characteristics predict these responses. The data of 373 Finnish child–teacher–mother triads (178 girls, 195 boys) were analysed. Teachers and mothers reported their instructional support and affective responses toward a child in the school/homework context in Grades 1, 2, 3, and 4. At the beginning of Grade 1, the children’s performance in reading and math was tested, and teachers evaluated the children’s externalizing and internalizing problem behaviour. The results demonstrated that mothe…

Expression of Toll-Like Receptors in the Developing Brain

2012

Toll-like receptors (TLR) are key players of the innate and adaptive immune response in vertebrates. The original protein Toll in Drosophila melanogaster regulates both host defense and morphogenesis during development. Making use of real-time PCR, in situ hybridization, and immunohistochemistry we systematically examined the expression of TLR1-9 and the intracellular adaptor molecules MyD88 and TRIF during development of the mouse brain. Expression of TLR7 and TLR9 in the brain was strongly regulated during different embryonic, postnatal, and adult stages. In contrast, expression of TLR1-6, TLR8, MyD88, and TRIF mRNA displayed no significant changes in the different phases of brain develop…

Protein kinase activities associated with ribosomes of developing rat brain. Identification of eukaryotic initiation factor 2 kinases.

1986

Protein kinases associated with ribosomes in the brains of suckling (4-10 days) and adult (2 months) rats were extracted from ribosomal fraction with 0.5 M KCl. The different protein kinase activities were characterized by their ability to phosphorylate three exogenous substrates: casein, histone IIs and histone IIIs in the presence of different modulators. Ribosomal salt wash fractions contain a high casein kinase activity which was partially inhibited by heparin and stimulated by calmodulin in the presence of Ca2+, indicating the presence of casein kinase I and II and calcium/calmodulin-dependent kinases. Cyclic AMP and cyclic GMP-dependent kinases and protein kinase C (calcium/phospholip…

Recent patents and advances in hepatocyte-like cells differentiation by mesenchymal stem cells

2013

Chronic liver diseases constitute one of the main causes of death in western countries. Orthotopic liver transplantation still remains the final therapeutic approach to these diseases, but alternative therapeutic strategies are actively researched. Hepatocyte transplantation is considered a promising approach, even if this technique presents many limitations. These factors boosted the research for alternative cell sources to derive functional hepatocytes. In the last years, research on basic biology and differentiative ability of adult, embryonic and perinatal stem cells has constantly increased. The term "perinatal" indicates stem cell populations derived from foetal sources such as placen…

Antioxidant and glutathione-related enzymatic activities in rat sciatic nerve

1990

Abstract The present work tries to establish the antioxidant capacity of the peripheral nervous tissue of the rat, in terms of the enzymatic activities present in this tissue that either prevent the formation of activated species as the semiquinone radical (DT-diaphorase), protect against activated oxygen species (superoxide dismutase, glutathione peroxidase), conjugate natural toxic products or xenobiotics (glutathione S-transferases, especially the activity conjugating 4-hydroxy-nonenal), or complete the glutathione system metabolism (glutathione disulfide reductase, γ-glutamyl transpeptidase). All the activities studied are lower in this tissue than they are in liver, except for γ-glutam…

Resveratrol and stroke: from chemistry to medicine.

2014

Stroke is one of the most common cardiovascular diseases and is known as a leading cause of death in the world. Despite to its high prevalence, there are limited effective therapeutic strategies for stroke till now. However, oxidative stress plays an important role in the pathogenesis of stroke and therefore, antioxidant therapy could be used as a new therapeutic strategy. Among the antioxidants, some natural compounds are very interesting due to their low adverse effects. Resveratrol (3, 5, 4'-trihydroxystilbene) is a natural polyphenolic antioxidant found in grape skin, grape products, and peanuts as well as in red wine. In recent years, much attention has been paid to resveratrol due to …

Transcriptomic metaanalyses of autistic brains reveals shared gene expression and biological pathway abnormalities with cancer

2019

Este es el artículo que se ha publicado de forma definitiva en: https://molecularautism.biomedcentral.com/articles/10.1186/s13229-019-0262-8 En este artículo también participa Joan Climent, Vera Pancaldi, Lourdes Fañanás, Celso Arango, Mara Parellada, Anaïs Baudot, Daniel Vogt, John L. Rubenstein, Alfonso Valencia y Rafael Tabarés-Seisdedos. Background: Epidemiological and clinical evidence points to cancer as a comorbidity in people with autism spectrum disorders (ASD). A significant overlap of genes and biological processes between both diseases has also been reported. Methods: Here, for the first time, we compared the gene expression profiles of ASD frontal cortex tissues and 22 cancer t…

Prenatal cocaine exposure alters spontaneous and cocaine-induced motor and social behaviors.

2005

The abuse of cocaine in pregnant women could affect emotional behaviors in their descendents. The aim of this work was to evaluate the effects of prenatal cocaine exposure on spontaneous and cocaine-induced motor and social behaviors in mice. Three kinds of prenatal treatment were used: non-treated animals; mice treated daily with physiological saline during the last week of pregnancy; and finally, those treated with cocaine (25 mg/kg) during the same period. Behavioral studies took place on adult males, which were housed in two different conditions: grouped (non-aggressive), or isolated (aggressive). Cocaine-pretreated animals exhibited slight differences in spontaneous motor activity, but…
