The brain is a high-energy demanding organ, consuming around 20% of the metabolic energy generated. To fulfill this demand, cerebral blood flow(CBF) supplies oxygen and glucose continuously through the intricate network of cerebral blood vessels. Although for many years brain activity and blood flow were conceived as independent processes, MRI-based functional brain imaging demonstrated that there is a coupling between them,

Faith and Belief in Autism in Cote d’Ivoire: About Judith, God’s Strange Gift

引用

Case Reports in Clinical Medicine 2024年第1期13卷 1-11页

作者： anna-Corinne Bissouma Lawrence Yapi Center Marguerite Té Bonle National Institut of Public Health Abidjan Cote d’Ivoire Psychology department Felix Houphouet-Boigny University Abidjan Cote d’Ivoire

Faced with autism, motherhood and parenthood are turned upside down in many ways. Coping with stress and mental health problems, continuing to assume a rewarding parental role and finding suitable care are the trials and tribulations that mark out the journey of African parents. Faith and belief have been described as providing meaning and coping mechanisms in the frightening ordeal of disability. An encounter with a young girl and her parents provided an opportunity to analyse the mother’s experience and the impact of beliefs and discourses on her commitment to care. Based on this clinical story, we discuss the place of other-actors (parents and carers) and the Other-God in relation to the psychopathological dynamics of the mother.

Cu/TiO_(2) Photocatalysts for CO_(2) Reduction: Structure and Evolution of the Cocatalyst Active Form

Transactions of Tianjin University 2024年第2期30卷 140-151页

Extensive work on a Cu-modified TiO_(2) photocatalyst for CO_(2) reduction under visible light irradiation was conducted. The structure of the copper cocatalyst was established using UV-vis diff use refl ectance spectroscopy, high-resolution transmis- sion electron microscopy, X-ray absorption spectroscopy, and X-ray photoelectron spectroscopy. It was found that copper exists in different states (Cu 0 , Cu^(+) , and Cu^(2+) ), the content of which depends on the TiO_(2) calcination temperature and copper loading. The optimum composition of the cocatalyst has a photocatalyst based on TiO_(2) calcined at 700℃ and modified with 5 wt% copper, the activity of which is 22 μmol/(h·g cat ) (409 nm). Analysis of the photocatalysts after the photocatalytic reaction disclosed that the copper metal on the surface of the calcined TiO_(2) was gradually converted into Cu_(2) O during the photocatalytic reaction. Meanwhile, the metallic copper on the surface of the noncalcined TiO_(2) did not undergo any trans- formation during the reaction.
