Comparative expression of cyclooxygenase 2 and Ki67 in amelanotic and conventional oral melanomas

2020

Background Oral melanomas have some histopathological resemblance with its cutaneous counterpart; however, an aggressive behavior is more common in tumors that occur in the oral cavity. Several markers have been suggested as indicative of tumoral progression and aggressiveness, such as cyclooxygenase 2 (COX-2) and Ki67. Material and Methods In this study, we have compared the expression of COX-2 and Ki67 in a series of amelanotic (n=7) and melanotic oral melanomas (n=22). The cases were selected from 4 pathology laboratories and submitted to the immunohistochemical (IHC) reactions. We analyzed the IHC staining based on a qualitative – using visual scores; and a computer-assisted method (qua…

The Vascularization of Experimental and Human Primary Tumors: Comparative Morphometric and Morphologic Studies

1998

The importance of the blood vessel system in solid tumors has given rise to an increasing interest in this system as a direct target for tumor therapy, i.e. vascular targeting (Denekamp, 1984). Furthermore, its importance as a route for delivery of anticancer drugs (chemo- and immunotherapies) or photosensitizers (photodynamic laser therapy), as well as its modulatory influences on radiotherapy and hyperthermia — the former greatly depending on the amount of oxygen available, the latter on heat transfer — are evident. Numerous studies on the energy metabolism of solid tumors (Vaupel et al., 1987, 1989) have pointed out the functional importance of the blood vessel system and stress the need…

Electronic structure, lattice dynamics and thermodynamic stability of paramelaconite Cu4O3

2014

Abstract An ab initio study of the electronic structure, lattice dynamic and thermodynamic properties of paramelaconite Cu 4 O 3 is reported. The insulating, mixed-valence character of Cu 4 O 3 is elucidated by analyzing the band structure and the spin-orbital symmetry of the Cu-3 d hole states. Exchange coupling constants between Cu 2+ ions are computed which confirm the frustrated antiferromagnetism of the spin lattice. The lattice dynamics is studied from first principles and main features of the vibrational spectrum are assigned to the different chemical species Cu + , Cu 2+ and O. The thermodynamic stability of Cu 4 O 3 is investigated by calculating the free energy of the decompositio…

Ses racines et son développement de 1820 à 1920

2017

The aim of the study is to examine the Saami book history in the context of Finland in order to understand its evolution from 1820 to 1920. The study focuses on books and other printed materials in Saami language(s) (or idioms) and it looks into archival documents to throw light on their intellectual history. The Saami book history has unfolded slowly, and occasionally, it has appeared to fall into decline. The present study follows the French school of book history that uses multidisciplinary methods to examine books as a reflection of ideology in the context of a given culture at a given time. Such an approach allows us to see how a minority can express itself, what possibilities there ar…

German and Austrian occupant literature on the Sami in Norway and Lapland – “Harmless” minority, a resource, and well-off “reindeer kings”

2020

Source at http://urn.fi/URN:NBN:fi:jyu-202006234344. In previous research on the history of the Second World War in Finland and Norway, relations between the German and Austrian occupying forces and the Sami people have generally been considered to be good. The occupant gaze upon the Sami has been interpreted as exoticizing and “touristic”. Historical encounters and the Sami position in the literary discourse are discussed and explained in this article, using a selection of German and Austrian wartime and post-war literature. The discursive reading the sources bear evidence of multiple ways of relating to the Sami, from benign to racializing; from demeaning to one filled with surprise at un…

Ziliarkörpermetastase als Ersthinweis auf ein kleinzelliges Bronchialkarzinom1

2000

BACKGROUND About 3-10% of patients suffering from metastatic disease develop metastatic choroidal tumors. In this case report ocular symptoms were the first sign of a systemic malignancy. CASE REPORT A 65-year old man complained of an increasing painful redness of his left eye. He showed a white mass with 10 mm in thickness in the temporal chamber angle with "pseudohypopyon" and secondary glaucoma. Because of increasing pain the eye was removed. Histologic examination showed a small cell carcinoma of the ciliary body with high malignancy, which most probably has to be seen as a metastasis of a carcinoma of the lung, which was detected by internal examination concurrently. In addition, a met…

Saamenkielinen kirjahistoria Suomessa

2017

Suomessa kirjahistoria on pyrkinyt tarkastelemaan vanhaa suomenkielistä kirjallisuutta. Sen sijaan Suomen saamelainen kirjahistoria on jäänyt varjoon. Syynä voi olla sen hidas kehitys, joka alkoi paljon myöhemmin ja katkonaisemmin. Ensimmäisille saamennetuille kirjoille myönnettiin painolupa vasta kaksi sataa vuotta ensimmäisten saamenkielisten teosten julkaisemisen jälkeen. nonPeerReviewed
