Effect of Studentsā Reflection on their Teaching Practice Experiences: Discussions during Case Conferences in Teaching Practice
The purpose of this study was to clarify the effect of reflecting by student A, who participated in a teaching practice. As a result, the following three points were clarified. First, student A made more comments at case conferences than student teacher B. Moreover, student A made more comments concerning āalternativesā in which studentsā reflections appear in case conferences than student teacher B. Second, the studentsā reflections at case conferences revealed a commonly shared viewpoint on āteaching skillsā. Student A also held the viewpoint of an āapproach to the objectiveā and that the content of the class was appropriate to the goal of the lesson. Regarding the difference between student A and student teacher B, it was suggested that the mentoring received by student A from mentor D during the teaching practice had some degree of influence. Third, both student A and student teacher B has difficulties with āschoolchild understandingā despite mentor D talking at case conferences about this issue. Based on these findings, it is suggested that it is difficult to engage in reflection that enables student to comprehend āschoolchild understandingā in teaching practice
Successful Allogeneic Bone Marrow Transplantation Using Immunosuppressive Conditioning Regimen for a Patient with Red Blood Cell Transfusion-Dependent Pyruvate Kinase Deficiency Anemia
Pyruvate kinase deficiency (PKD) is the rare glycolytic enzyme defect causing hemolytic anemia. Treatments are mainly red cell transfusion and/or splenectomy, leading to iron overload. Allogeneic bone marrow transplantation (BMT) is alternatively curative treatment for severe PKD. The intensity of conditioning is often controversial because of higher risk of graft failure and organ damage. Here, we present a transfusion-dependent PKD patient undergoing BMT from an HLA-identical sibling using intensively immunosuppressive conditioning regimen. This report suggests that BMT using immunosuppressive conditioning regimen may be a feasible and effective treatment for patients with severe PKD with iron overload. We suggest the timing of the transplantation at an earlier age in severe PKD predicted from gene mutation is preferred before cumulative damage of transfusion
A Single Neonatal Injection of Ethinyl Estradiol Impairs Passive Avoidance Learning and Reduces Expression of Estrogen Receptor Ī± in the Hippocampus and Cortex of Adult Female Rats.
Although perinatal exposure of female rats to estrogenic compounds produces irreversible changes in brain function, it is still unclear how the amount and timing of exposure to those substances affect learning function, or if exposure alters estrogen receptor Ī± (ERĪ±) expression in the hippocampus and cortex. In adult female rats, we investigated the effects of neonatal exposure to a model estrogenic compound, ethinyl estradiol (EE), on passive avoidance learning and ERĪ± expression. Female Wistar-Imamichi rats were subcutaneously injected with oil, 0.02 mg/kg EE, 2 mg/kg EE, or 20 mg/kg 17Ī²-estradiol within 24 h after birth. All females were tested for passive avoidance learning at the age of 6 weeks. Neonatal 0.02 mg/kg EE administration significantly disrupted passive avoidance compared with oil treatment in gonadally intact females. In a second experiment, another set of experimental females, treated as described above, was ovariectomized under pentobarbital anesthesia at 10 weeks of age. At 15-17 weeks of age, half of each group received a subcutaneous injection of 5 Ī¼g estradiol benzoate a day before the passive avoidance learning test. Passive avoidance learning behavior was impaired by the 0.02 mg/kg EE dose, but notably only in the estradiol benzoate-injected group. At 17-19 weeks of age, hippocampal and cortical samples were collected from rats with or without the 5 Ī¼g estradiol benzoate injection, and western blots used to determine ERĪ± expression. A significant decrease in ERĪ± expression was observed in the hippocampus of the estradiol-injected, neonatal EE-treated females. The results demonstrated that exposure to EE immediately after birth decreased learning ability in adult female rats, and that this may be at least partly mediated by the decreased expression of ERĪ± in the hippocampus
A rare case of allergic bronchopulmonary mycosis complicating pulmonary pleomorphic carcinoma
Abstract A 72āyearāold man with productive cough and wheezing was referred to our institution for a growing mass shadow and central bronchiectasis in the right lower lobe on computed tomography. Based on the symptoms, elevated Aspergillusāspecific immunoglobulin E levels, and radiological findings, allergic bronchopulmonary mycosis (ABPM) was suspected according to the Japanese clinical diagnostic criteria. The patient refused bronchoscopic examination, and oral prednisolone (0.5āmg/kg/day) improved the symptoms; however, the mass shadow continued to grow. Subsequently, bronchoscopy revealed mucus plugs and an endobronchial tumour with a whitish surface. The tumour was surgically resected, and the pathological diagnosis was a coexistence of ABPM and pulmonary pleomorphic carcinoma. To the best of our knowledge, this is the first case of ABPM developing at the site of pulmonary pleomorphic carcinoma. Careful bronchoscopic examinations and histopathological evaluations of the surgical specimen led to a prompt and accurate diagnosis
