Letter from [William] J. Fujimoto, from the stockade, to Mr. [Raymond R.] Best, Project Director, February 23, 1944
No full textDescribes Fujimoto's imprisonment, for 34 days at the time of writing; Fujimoto states that the cause for his arrest has never been made clear, especially given that he has "never entertained radical ideas" and has been cooperative with authorities, and requests a meeting with Best to review his case.The Willard Schmidt collection, documents some of the administrative duties of Willard Schmidt, the Chief of Internal Security for the War Relocation Authority and the Tule Lake incarceration/segregation camp. This collection contains administrative records and photos documenting the Tule Lake camp, the largest incarceration camp with a peak population of 18,789 and with the most turbulent history. In 1943, the camp was turned into a segregation center to house "disloyal" Japanese Americans relocated from other camps based on their answers to a confusing loyalty questionnaire. The camp endured martial law from November 1943- Jan 1944 after escalating protests and unrest. The hostile environment of the camp lead to many incarcerees renouncing their American citizenship upon the end of incarceration, a process which took 14 years to reverse if they did not wish to be deported to Japan
Doença de Kikuchi e Fujimoto
No full textA doença de Kikuchi e Fujimoto, também conhecida como Linfadenite Histiocítica
Necrosante, é uma entidade clínico-patológica rara cuja etiologia permanece
desconhecida; tem sido sugerida a possibilidade de uma etiologia auto-imune, mas também tem sido descrita a associação com algumas infecções víricas.
Os autores apresentam o caso clínico de uma adolescente de 14 anos internada por
febre persistente, volumosa tumefacção cervical e alteração do estado geral.
Dos exames complementares efectuados a citologia aspirativa e a biopsia ganglionar
levaram ao diagnóstico da doença de Kikuchi e Fujimoto.
Após a instituição da corticoterapia, verificou-se uma notória melhoria do quadro clínico
Commodity Content in a General Input-Output Model
No full textThis technical paper provides a definition of ‘commodity content’ in extended von Neumann–
Morishima models of production. Our definition admits as special cases the classical definition of
‘labour values’ in Leontief models, as well as Morishima’s definition of ‘optimal values’ in a von
Neumann model. Proper joint production, heterogeneous labour, durable consumption goods, household
activities and disposal processes are all allowed for. We also propose a tentative mathematical
criterion for defining bads and for distinguishing between unskilled and skilled labour
COMMODITY CONTENT IN A GENERAL INPUT-OUTPUT MODEL: A REPLY TO BELLINO, YOSHIHARA AND VENEZIANI
No full textEnfermedad de Kikuchi-Fujimoto: presentación de un caso pediátrico
No full textLa enfermedad de Kikuchi-Fujimoto, o linfadenitis necrosante histiocítica, es una afección benigna, poco frecuente, generalmente de resolución espontánea, en un periodo de seis meses. La presentación
clínica característica incluye linfadenopatía cervical, leucopenia y síndrome febril prolongado. Se presenta con mayor frecuencia en mujeres asiáticas jóvenes y existen pocas descripciones de esta
enfermedad en la población pediátrica.
Frecuentemente simula linfadenitis tuberculosa, linfoma maligno, lupus eritematoso sistémico y muchas otras condiciones benignas y malignas. La etiología es desconocida; sin embargo, se ha sugerido un origen viral o autoinmunitario. Los hallazgos de laboratorio generalmente son inespecíficos, siendo los más frecuentes la leucopenia, el aumento de la sedimentación globular, la anemia y la presencia de anticuerpos antinucleares.
En vista de lo inespecífico de las manifestaciones clínicas y de laboratorio, el hallazgo histológico es lo que permite definir el diagnóstico. El diagnóstico temprano es importante, entre otras razones para evitar el uso inapropiado de antibióticos.
Se describe el caso de una paciente de 10 años, con síndrome febril prolongado y adenopatías cervicales secundarias a enfermedad de Kikuchi-Fujimoto
Immunohistochemical localization of interferon-gamma in normal human ovary
No full textThere is increasing evidence that cytokines are important intraovarian non-steroidal regulators. The aim of the present study was to evaluate the presence in the human ovary of interferon (IFN)-gamma, a cytokine produced by T lymphocytes after mitogenic or antigenic stimulation. Very low levels of IFN-gamma (0.025-0.057 IU/ml) were found in follicular fluid of large spontaneously maturing follicles, in the ovarian vein (< 0.01-0.079 IU/ml) or peripheral blood (< 0.01-0.06 IU/ml). The avidin-biotin immunocytochemical technique, with appropriate monoclonal antibodies, was used to localize IFN-gamma-positive cells, human leukocyte antigen (HLA)-DR molecules, activated T cells, T helper/inducer cells and T cytotoxic/suppressor cells. IFN-gamma-positive cells were only detected in preovulatory follicles, associated with the follicular basal lamina, thecal vessels and interstitial tissue. In the same large follicles very few T helper/inducer cells were detected, but a high proportion of T lymphocytes expressed the CD8 phenotype in the theca, interstitial tissue and follicular cavity. No IFN-gamma-positive cells were observed in preantral and small antral follicles. The results indicate that the human ovary contains immunoreactive IFN-gamma, suggesting that the cytokine plays a paracrine role in human ovarian function
Nonlinear input-normal realizations based on the differential eigenstructure of hankel operators
No full textThis paper investigates the differential eigenstructure of Hankel operators for nonlinear systems. First, it is proven that the variational system and the Hamiltonian extension with extended input and output spaces can be interpreted as the Gâteaux differential and its adjoint of a dynamical input-output system, respectively. Second, the Gâteaux differential is utilized to clarify the main result the differential eigenstructure of the nonlinear Hankel operator which is closely related to the Hankel norm of the original system. Third, a new characterization of the nonlinear extension of Hankel singular values are given based on the differential eigenstructure. Finally, a balancing procedure to obtain a new input-normal/output-diagonal realization is derived. The results in this paper thus provide new insights to the realization and balancing theory for nonlinear systems.
Patientin mit hypopharyngealer Kikuchi-Fujimoto-Lymphadenopathie (KFD)
No full textEinleitung: Die Kikuchi-Fujimoto-Lymphadenopathie ist eine kaum bekannte, selbstlimitierende, unterdiagnostizierte Erkrankung mit exzellenter Prognose. Die Differentialdiagnostik unklarer rundlicher Veränderungen im Bereich der zervikalen Lymphknoten läßt bei Patienten jenseits des 40. Lebensjahres an Malignome oder Metastasen von solchen denken, während beim Alterssegment vom 16.-40. Lebensjahr am ehesten ein Lymphom ausgeschlossen werden muss. Methoden: Eine 30-jährige Patientin stellte sich mit seit 4 Wochen bestehenden Schluckbeschwerden. Es bestand kein allgemeines Krankheitsgefühl mit Abgeschlagenheit und Leistungsknick. Eine antibiotische Therapie hatte keine Besserung erbracht. Endoskopisch zeigten sich zwei, mehr als 1,5 cm große kugelige Vorwölbungen im Bereich des Zungengrundes auf der lingualen Epiglottisfläche aufliegend. Laborchemisch und insbesondere serologisch ergab sich kein kausaler Hinweis für die Befunde. Bei Verdacht auf das Vorliegen eines Malignoms/malignen Lymphoms erfolgte eine Panendoskopie mit vollständiger Abtragung beider Befunde. Ergebnisse: Die Histologie und die Immunhistochemie ergaben die Diagnose einer subakuten histiozytär-nekrotisierenden Lymphadenitis (Kikuchi-Fujimoto-Lymphadenitis). Schlussfolgerung: Die Kikuchi-Fujimoto-Lymphadenitis ist eine in Mitteleuropa seltene Differentialdiagnose bei unklaren Raumforderungen im Bereich der Halslymphknoten. Der klinische Befund läßt bei der Seltenheit der Inzidenz in Mitteleuropa schneller an Malignome, Malignommetastasen oder maligne Lymphome denken. Eine Diagnosesicherung läßt sich durch eine Lymphknotenexstirpation erreichen. Bei guter Prognose ist diese symptomatische Behandlung gleichzeitig auch die Therapie.Der Erstautor gibt keinen Interessenkonflikt an
Clonal T-cell proliferations occasionally occur in Kikuchi–Fujimoto disease
No full textKikuchi-Fujimoto disease (KFD) is a benign self-limiting disorder that frequently leads to swelling of cervical lymph nodes in young women. It has a characteristic histologic appearance with sharply demarcated foci containing apoptotic debris, histiocytes, and proliferating large T-cells. Since in the past years, core needle biopsies have been increasingly used for diagnostic work-up, a small biopsy of the pathognomonic proliferating T-cell foci may lead to misinterpretation as a large T-cell neoplasia. The aim of the present study therefore was to analyze how frequently clonal T-cell receptor (TCR) amplificates may be obtained in KFD using a commonly used TCR gamma rearrangement clonality assay. In 88 KFD cases, TCR gamma clonality assays could be successfully applied. Clonal peaks of TCR gamma in front of a polyclonal background were observed in 15 cases (18%). The investigated clinical parameters (age, gender, extent of infiltration of the lymph node, percentage of proliferative compart-ment) did not differ between patients with detectable TCR gamma clones from those patients who had polyclonal TCR gamma results
