Distribution of keratin subtypes in the thymus of Japanese black calves during acute thymic involution.

Immunohistochemistry for keratins 5, 8, 14, and 18 was performed on Japanese Black calf thymuses at various stages of acute thymic involution. Keratins 5 and 14 were predominantly localized in the thymic medulla, while keratins 8 and 18 were broadly distributed throughout the parenchyma. Despite thymic involution, the distribution patterns of these keratins remained consistent.

[The role of psychiatrists in cooperative activity with school staff in school mental health].

Although it was started some ten years ago in Japan that psychiatrists should be involved as specialists in mental health activity in schools, what was expected at most was to give some therapeutic suggestions on inquiry by teachers in relation to desirable solutions to reduce problem behaviors as pathological symptoms. However, it is now beginning to be acknowledged by psychiatrists that they should not only help to reduce the already appearing severe symptoms, but also to maintain and even promote the mental health conditions of all school children and adolescents irrespective of whether symptoms are already present or not. The most useful activity for school teachers to be engaged in regarding both therapeutic and preventive mental health activities with certain positive results is to learn from case consultation in schools that they belong to with the attendance of psychiatrists about single symptoms after identifying them by themselves, and to know whether the single symptom really exists alone or is a component of a certain disorder, and also the cause of the symptom or the disorder.

A study of executive functions in delinquents with developmental disabilities within a Japanese reformatory.

Many attempts have been made to address the relation between antisocial behavior and executive function deficits. The purpose of this paper is to evaluate executive functions in juvenile delinquents with developmental disabilities by using the Behavioral Assessment of the Dysexecutive Syndrome (BADS), and then cross referencing this to their performance on Wechsler IQ Test, Das Naglieri Cognitive Assessment System (DN-CAS), and Rey's Auditory Verbal Learning Test (AVLT). The data was collected from 164 participants with Mental Retardation (MR), Pervasive Developmental Disorder (PDD), and Attention Deficit-Hyperactivity Disorder (ADHD), and a factor analysis was applied to results of the BADS.

Risk group stratification to predict recurrence after transurethral resection in Japanese patients with stage Ta and T1 bladder tumours: validation study on the European Association of Urology guidelines.

Objective: • To validate the European Association of Urology (EAU) guidelines on risk group stratification to predict recurrence in Japanese patients with stage Ta and T1 bladder tumours.

Patients And Methods: • A cohort of 592 Japanese patients who were treated with transurethral resection (TUR) and histopathologically diagnosed with Ta and T1 urothelial carcinoma of the bladder were enrolled in this retrospective study. • The primary endpoint of the present study was recurrence-free survival, and the median follow-up duration was 37 months in recurrence-free survivors.
