Colonization of adrenal glands and ovaries of mice by variants of HSV 1 and 2

1991

The herpes simplex virus (HSV)-infected mouse model was used to correlate histopathological lesions in adrenal glands and ovaries with the localisation of viral nucleic acids and viral antigens, employing in situ hybridization and immunohistochemistry. In the adrenals, the lesions were mainly restricted to the zona fasciculata and the zona reticularis, sometimes extending to the medulla. In the ovaries, lesions were detected in follicles and in the stroma. During the course of infection, HSV nucleic acids could be detected earlier than HSV proteins. Next to the center of necrotic foci mainly HSV proteins were detected, whereas peripheral cells were found to contain viral nucleic acids. In s…

Ortho -Functionalized Aryltetrazines by Direct Palladium-Catalyzed C−H Halogenation: Application to Fast Electrophilic Fluorination Reactions

2016

International audience; A general catalyzed direct C-H functionalization of s-tetrazines is reported. Under mild reaction conditions, N-directed ortho-C-H activation of tetrazines allows the introduction of various functional groups, thus forming carbon-heteroatom bonds: C-X (X=I, Br, Cl) and C-O. Based on this methodology, we developed electrophilic mono- and poly-ortho-fluorination of tetrazines. Microwave irradiation was optimized to afford fluorinated s-aryltetrazines, with satisfactory selectivity, within only ten minutes. This work provides an efficient and practical entry for further accessing highly substituted tetrazine derivatives (iodo, bromo, chloro, fluoro, and acetate precurso…

Īpašuma tiesību aprobežojumi īpaši aizsargajāmās dabas teritorijās.

2021

Maģistra darba tēma "Īpašuma tiesību aprobežojumi īpaši aizsargājamās dabas teritorijās". Latvijas valsts teritorijā ir liela dabas daudzveidība, kura sevī ietver īpaši aizsargājamas dabas teritorijas. Īpaši aizsargājamas dabas teritorijas noteiktas ar mērķi aizsargāt esošo dabas daudzveidību. Taču, aizsargājot dabas vērtības, tiek ierobežotas īpašuma tiesības personām, kuru īpašumi atrodas īpaši aizsargājamajās dabas teritorijās. Lai vienlaicīgi saglabātu personas tiesības uz īpašumu un dabas daudzveidību , ir noteikti kompensāciju mehānismi, kas atvieglo noteiktos īpašuma tiesību aprobežojumus. Nosakot īpašuma tiesību aprobežojumu apmēru īpaši aizsargājamās dabas teritorijās ,ir jāvērtē t…
