Od 21 do 27 VIII 2022 r. odbywał się w Poznaniu XXIII Międzynarodowy Kongres Nauk Historycznych. Wydarzenie to miało ogromne znaczenie dla wszystkich naukowców zajmujących się przeszłością. Od 1900 r. historycy z całego świata organizują kongresy w celu przedyskutowania najbardziej palących tematów, przedstawienia wyników swoich badań i budowania sieci międzynarodowej współpracy. W 1926 r. powołali do życia Międzynarodowy Komitet Nauk Historycznych (ICHS) jako organizację pozarządową, którą tworzą komitety narodowe reprezentujące kraje członkowskie oraz komisje specjalistyczne zajmujące się konkretnymi dziedzinami badań. Głównym celem Komitetu jest promowanie nauk historycznych przez współpracę międzynarodową. Komitetowi powierzono organizowanie co pięć lat kolejnych kongresów we współpracy z historykami z kraju-gospodarza. Jak dotąd kongres odbył się
Introduction. Autoimmune blistering diseases are mediated by autoantibodies directed against structural proteins of the skin. Pemphigus vulgaris (PV) is the most common type of pemphigus. The main auto-antigen in PV is desmoglein 3, although other antigens such as desmoglein 1, desmocollins, plakoglobin and pemphaxin may also be involved. More than 50% of cases begin with oral lesions. Skin lesions on the face appear occasionally. Objective. To present an unusual clinical manifestation of pemphigus vulgaris. Case report. We present a case of a 54-year-old female patient with skin lesions localized on the nose, who due to suspicion of skin cancer not confirmed by histopathology was referred to us by an oncologist. Pemphigus vulgaris was suspected when erosions on the oral mucosa were observed, and this diagnosis was established on the basis of immunological tests. The patient was treated with prednisone and azathioprine, with very good results. Conclusions. We present the case owing to the difficulties in the diagnostic process and, moreover, due to spectacular clinical improvement after the treatment. streszczenie Wprowadzenie. Pęcherzyca zwykła jest najczęstszą autoimmunologiczną odmianą pęcherzycy. Charakteryzuje ją obecność autoprzeciwciał skierowanych przeciwko strukturalnym białkom naskórka. Ponad 50% przypadków rozpoczyna się zmianami w obrębie błony śluzowej jamy ustnej, natomiast zmiany skórne zlokalizowane na twarzy obserwuje się rzadko. Cel pracy. Przedstawienie przypadku nietypowej manifestacji klinicznej pęcherzycy zwykłej. Opis przypadku. Przedstawiamy przypadek pacjentki skierowanej do Kliniki Dermatologii w Zabrzu z Centrum Onkologii w Gliwicach z podejrzeniem raka podstawnokomórkowego skóry nosa z prośbą o konsultację dermatologiczną. U pacjentki był planowany zabieg usunięcia chirurgicznego zmiany, ale ze względu na niejasny obraz histopatologiczny skierowano ją do dermatologa. Pogłębiona diagnostyka, jak również zmiany, które pojawiły się na błonach śluzowych jamy ustnej, pozwoliły na ustalenie rozpoznania pęcherzycy zwykłej.
There is experimental evidence of high vibronic activity that accompanies the strongly allowed transition between the ground state and the lowest electronic singlet excited state of oligofurans that contain 2,3, and 4 furan rings. The absorption and emission spectra of the three lowest oligofurans measured in liquid nitrogen temperature show distinct fine structures that are reproduced using the projection-based model of vibronic coupling (with Dushinsky rotation included) parameterized utilizing either DFT (with several different exchange-correlation functionals) or ab initio (CC2) quantum chemistry calculations. Using as reference the experimental data concerning the electronic absorption and fluorescence for the 8 lowest oligofurans we first analyze the performance of the exchange-correlation functionals for the electronic transition energies and the reorganization energies. Subsequently, we use the best functionals alongside the CC2 method to explore how the reorganization energies are distributed among the totally symmetric vibrations, identify the normal modes that dominate in the fine structures present in the absorption and emission bands, and trace their evolution with the increasing number of rings in the oligofuran series. Confrontation of the simulated spectra with the experiment allows for verification of the performance of the selected DFT functionals and the CC2 method.
