Biochemical identification and tissue-specific expression patterns of keratins in the zebrafish Danio rerio
1998
We have identified a number of type I and type II keratins in the zebrafish Danio rerio by two-dimensional polyacrylamide gel electrophoresis, complementary keratin blot-binding assay and immunoblotting. These keratins range from 56 kDa to 46 kDa in molecular mass and from pH 6.6 to pH 5.2 in isoelectric point. Type II zebrafish keratins exhibit significantly higher molecular masses (56-52 kDa) compared with the type I keratins (50-48 kDa), but the isoelectric points show no significant difference between the two keratin subclasses (type II: pH 6.0-5.5; type I: pH 6.1-5.2). According to their occurrence in various zebrafish tissues, the identified keratins can be classified into "E" (epider…
Nachweis von alpha1-Fetoprotein an Blutspuren mit Hilfe der Celluloseacetatfolien-(CAF)-Elektrophorese
1977
Die von Patzelt, Geserick und Lignitz fur Agargelelektrophorese zum Nachweis von alpha1-Fetoprotein beschriebene Technik konnte mit Erfolg auf das Celluloseacetatfolien-(CAF)-System ubertragen werden. Die Unterscheidbarkeit von Neugeborenen- oder Fetalblut und Erwachsenenblut wurde an 219 Neugeborenenbluten gepruft, die auf verschiedenen Spurentragern (Glas, Holz, Filterpapier und Leinen) getrocknet worden waren und gelang ausnahmslos nach Lagerung bei Zimmertemperatur bis zu einem Spurenalter von 8 Monaten. Die Spurentrager beeinflusten die Darstellung nicht.
Einflu� von Medikamenten auf den Acetaldehydspiegel im Blut nach Alkoholzufuhr (enzymatische Bestimmung des Acetaldehyd)
1957
Mit einer enzymatischen und damit spezifischen Bestimmung des Acetaldehyd in Korperflussigkeiten konnte folgendes festgestellt werden. 1. Im Blutserum von Ratten konnte in der Mehrzahl der Falle keine Acetaldehydkonzentration bestimmt werden, im Einzelfall jedoch bis zu 0,09 mg- %. Die bisher in der Literatur angegebenen Normwerte hinsichtlich des Acetaldehydgehaltes, die aber mit relativ unspezifischen Methoden bestimmt worden waren, liesen sich an Ratten nicht bestatigen. 2. Die bisher mitgeteilten Konzentrationen an Acetaldehyd nach Verabreichung einer Sattigungsdosis von Antabus und Alkohol liegen uber 2 mg- %. Auch bei Uberprufung dieser Versuchsanordnung konnte niemals die Hohe dieser…

Hating Adolescents Test (HAT): a preliminary development of a measure to assess hating among adolescents
2020
The phenomenon of haters is becoming common among adolescents. The aims of the present research were to evaluate the preliminary psychometric properties of the Hating Adolescents Test (HAT), an ad hoc questionnaire created to evaluate online and offline hate (Study 1), and possible risk factors connected with hate (Study 2). Participants (202 female and 200 male) of this study completed the HAT, the How I Think Questionnaire, the Buss–Perry Aggression Questionnaire, and the Penn State Worry Questionnaire. Descriptive statistics were calculated, and exploratory factor analysis and confirmatory factor analysis were applied. Preliminary data suggest how males reported higher level of hate than…
Comparing deep‐end confinement in England & Wales and Norway
2022
Extreme forms of custody represent the boundary points of state power. The configuration of the most restrictive corners of prison systems, and what goes on within them, is highly instructive in exposing the objectives, limits, and implications of state coercion at its most severe. Based on data collected in England & Wales and Norway, this article has two main aims. The first is to explore the degree to which “deep-end” confinement differs between jurisdictions with different penal philosophies. The second is to understand how the most extreme form of confinement in each jurisdiction differs from the more typical carceral experiences within each system and its overall penal ethos. Empirica…
Fabry Disease With Concomitant Lewy Body Disease
2019
AbstractAlthough Gaucher disease can be accompanied by Lewy pathology (LP) and extrapyramidal symptoms, it is unknown if LP exists in Fabry disease (FD), another progressive multisystem lysosomal storage disorder. We aimed to elucidate the distribution patterns of FD-related inclusions and LP in the brain of a 58-year-old cognitively unimpaired male FD patient suffering from predominant hypokinesia. Immunohistochemistry (CD77, α-synuclein, collagen IV) and neuropathological staging were performed on 100-µm sections. Tissue from the enteric or peripheral nervous system was unavailable. As controls, a second cognitively unimpaired 50-year-old male FD patient without LP or motor symptoms and 3…
B and T lymphocytes are affected in lysosomal disorders--an immunoelectron microscopic study.
1991
Circulating lymphocytes of four patients with mucopolysaccharidoses II and IIIA, four patients with juvenile neuronal ceroid-lipofuscinosis, one patient each with glycogenosis type II, infantile neuronal ceroid-lipofuscinosis, and Gaucher disease were classified by immunoelectron microscopy as B or T lymphocytes. Disease-specific lysosomal inclusions as well as non-specific lysosomal organelles, especially Gall bodies were identified in B and T lymphocytes. These non-quantitative studies indicate that both B and T lymphocytes participate in the lysosomal storage process.
Leishmania tarentolae and Leishmania infantum in humans, dogs and cats in the Pelagie archipelago, southern Italy.
2021
Visceral leishmaniasis (VL) caused by Leishmania infantum is endemic in the Mediterranean basin with most of the infected human patients remaining asymptomatic. Recently, the saurian-associated Leishmania tarentolae was detected in human blood donors and in sheltered dogs. The circulation of L. infantum and L. tarentolae was investigated in humans, dogs and cats living in the Pelagie islands (Sicily, Italy) by multiple serological and molecular testing. Human serum samples (n = 346) were tested to assess the exposure to L. infantum by immunofluorescence antibody test (IFAT), enzyme-linked immunosorbent assay (ELISA) and Western blot (WB) and to L. tarentolae by IFAT. Meanwhile, sera from do…
Tumor de células de la granulosa extraovárico con mutación FOXL2. Diagnóstico diferencial morfológico e inmunohistoquímico
2020
Extraovarian granulosa cell tumor is a very uncommon tumor and the identification of a recurrent mutation in FOXL2 may be used as another diagnostic tool along with the classical morphological and immunohistochemical findings. Here, we report a new case of extraovarian granulosa cell tumor in a 57 years old female patient presented with a sub-hepatic mass and abdominal pain. Histopathological examination of the excised mass showed features of adult-type granulosa cell tumor with α-inhibin, calretinin, WT1, S100, CD99 and progesterone receptor immunoreactivity. A FOXL2 mutation was detected on molecular biology study. A final diagnosis was an extraovarian adult-type granulosa cell tumor. We …
