Motivational and Methodological Factors Involved in the Helping Behavior Test in laboratory Rodents

引用

Journal of Behavioral and Brain Science 2024年第8期14卷 240-254页

作者： Gabriela F. Marinho jaqueline M. Wuo João Paulo Kurita Alvaro c. lima Regina H. Silva Pharmacology Department Federal University of So Paulo So Paulo Brazil

Empathy allows humans and other animals to share the emotional state of another, adopting that individual’s perspective on a given situation. This ability is fundamental for species living in groups. Helping behavior in laboratory animals has been used to study empathy. In this test, subjects are exposed to a conspecific that is trapped and learn to open the cage to release the other animal. However, the interpretation of helping behavior as an emphatically motivated action is still controversial. Here we review the studies that use the helping behavioral test proposed by Ben-Ami Bartal and colleagues in 2011 to better understand motivational factors for this behavior. In addition, we compare methodological aspects of these studies. In conclusion, helping behavior can be driven by empathy, but other factors such as the desire for social contact and learning components cannot be ruled out as motivators. In addition, studies focused on evaluating neurobiological mechanisms underlying helping behavior in laboratory rodents can help elucidate the factors involved in releasing the trapped co-specific.

Analysis of the genotoxic potential of low concentrations of Malathion on the Allium cepa cells and rat hepatoma tissue culture

引用

Journal of Environmental Sciences 2015年第10期27卷 102-111页

作者： jaqueline Bianchi Mario Sérgio Mantovani Maria Aparecida Marin-Morales Department of Biology Institute of BiosciencesSao Paulo State University(UNESP) Department of General Biology Biological Science CentreUniv Estadual de Londrina

Based on the concentration of Malathion used in the field, we evaluated the genotoxic potential of low concentrations of this insecticide on meristematic and F1 cells of Allium cepa and on rat hepatoma tissue culture（HTc cells）. In the A. cepa, chromosomal aberrations（cAs）, micronuclei（MN）, and mitotic index（MI） were evaluated by exposing the cells at 1.5,0.75, 0.37, and 0.18 mg/m l of Malathion for 24 and 48 hr of exposure and 48 hr of recovery time. The results showed that all concentrations were genotoxic to A. cepa cells. However,the analysis of the MI has showed non-relevant effects. chromosomal bridges were the cA more frequently induced, indicating the clastogenic action of Malathion. After the recovery period, the higher concentrations continued to induce genotoxic effects, unlike the observed for the lowest concentrations tested. In HTc cells, the genotoxicity of Malathion was evaluated by the MN test and the comet assay by exposing the cells at 0.09, 0.009, and0.0009 mg/5 m l culture medium, for 24 hr of exposure. In the comet assay, all the concentrations induced genotoxicity in the HTc cells. In the MN test, no significant induction of MN was observed. The genotoxicity induced by the low concentrations of Malathion presented in this work highlights the importance of studying the effects of low concentrations of this pesticide and demonstrates the efficiency of these two test systems for the detection of genetic damage promoted by Malathion.

Development of Biobased Poly(lactic Acid)/Epoxidized Natural Rubber Blends Processed by Electrospinning: Morphological, Structural and Thermal Properties

引用

Materials Sciences and Applications 2016年第4期7卷 210-219页

作者： jaqueline G. l. cosme Vanessa M. Silva Regina R. c. Nunes Paulo H. S. Picciani Institute of Macromolecules Federal University of Rio de Janeiro Rio de Janeiro Brazil

This article reports the production of electrospun fibers from blends of poly(lactic acid) (PlA) and epoxidized natural rubber (ENR) solutions. The produced fibers were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSc), thermogravimetric analysis (TGA) and dynamic mechanical analysis (DMA). SEM images showed the reduction in fiber size with ENR content of up to 25% in the mixture PlA/ENR. FTIR analysis revealed a possible interaction between carboxylic group of PlA and epoxi group of ENR. Thermal analysis showed the increase of the crystallinity fraction with ENR content and a decrease in thermal stability of eletrospun mats with the addition of ENR. The dynamic mechanical properties showed an enhancement of the stiffness of PlA/ENR blends with the increase of ENR content, which can support the production of interesting materials for tissue engineering based on renewable and biocompatible polymers. The reported properties indicate the possibility to use such fiber mats as potential materials in tissue engineering.

Background: Identifying factors associated with physical activity(PA) is useful in planning interventions and policies. The aim of this study was to identify sociodemographic, biological, and psychosocial factors associated with PA performed in school ***: Data collected for the present study included gender, age, socioeconomic status, body fat percentage, aerobic fitness, self-efficacy, attitudes,peer and parental support, and perception of school environment. Dependent variables were light-intensity PA(lPA) and moderate-to-vigorousintensity PA(MVPA) performed during school time, recesses, and physical education(PE) classes. Multiple regression analyses were ***: Participating adolescents(n = 567, 53% female, 12.9 ± 5.3 years) spent 5% of school time in MVPA and 27% in lPA, 15% of recesses in MVPA and 44% in lPA, and 16% of PE classes in MVPA and 41% in lPA. Boys engaged in more MVPA in all categories. Age was inversely related with MVPA and lPA in all periods, whereas body fat percentage was inversely related with MVPA in school time and PE classes. Attitude was inversely related with MVPA in all periods and with lPA in recesses. considering PA to be good and enjoyable was positively associated with MVPA in school ***: Adolescents spent little time in PA during school. Future interventions should implement enjoyable activities at school.
