Motoneurons of the stapedius muscle in the guinea pig middle ear: Afferent and efferent transmitters
2008
The objective of the present study was to identify efferent and afferent transmitters of motoneurons of the stapedius muscle of the middle ear in order to gain more insight into the neuronal regulation of the muscle. To identify motoneurons, we injected the fluorescent neuronal tracer Fluorogold (FG) into the muscle after preparation of the middle ear in adult guinea pigs. Upon terminal uptake and retrograde neuronal transport, we observed FG in neurons located medial and ventral to the nucleus of the facial nerve ipsilateral to the injection site. Immunohistochemical studies of these motoneurons showed that the majority contains calcitonin gene-related peptide. Our data further demonstrate…
Comparative Chemical Characterisation of Soils at Cypripedium Calceolus Sites in Latvia
2017
Abstract The main aim of the study was to evaluate the soil chemical characteristics of Cypripedium calceolus sites in Latvia for understanding of the species ecology, and its conservation problems and possibilities. Soil for 27 C. calceolus sites in Latvia was analysed during 2007-2015. The concentration of plant available essential nutrients (N, P, K, Ca, Mg, S, Fe, Mn, Zn, Cu, Mo, B), soil pH, electrical conductivity and concentration of organic matter were determined. Nutrient concentration of C. calceolus leaf samples from six sites were determined. The results demonstrated high heterogeneity in soil chemical composition with high variation for Ca, Mg, and Mn. The results suggest some …
Dzeltenās dzegužkurpītes Cypripedium calceolus L. demogrāfisko parametru ietekmējošie faktori Ķemeru Nacionālajā parkā
2017
Orhidejas, kā piemēram, dzeltenā dzegužkurpīte Cypripedium calceolus, ir viena no apdraudētākajām augu grupām pasaulē, jo tās ir šauri specializējušās un ļoti jutīgas pret izmaiņām biotopā. Līdz ar to, šo augu pētījumi mūsdienās ir arvien aktuālāki. Ķemeru Nacionālā parka trijās atradnēs 2016. gadā no maija līdz oktobrim tika ievākti dati, lai realizētu veiktā pētījuma mērķi – noskaidrot apgaismojuma un veģetācijas seguma ietekmi uz Cypripedium calceolus demogrāfiskajiem parametriem. Dati ievākti, izmantojot transekšu/parauglaukumu metodi, kur apļveida parauglaukumos (1,5 m rādiuss) noteica paaugā un pamežā esošās sugas un skaitu dažādās augstuma klasēs, kā arī vaskulāro augu un sūnu sugas …

Riflessioni sulla conventio in D. 2.14.1.3
2019
The author proposes a new interpretation of the well-known Ulpian’s and Pedius’ words contained in D. 2.14.1.3, which is based on the idea that ‘conventio’, despite its common assumption as equivalent of ‘consensus’ (in the abstract sense of subjective element of a contract), rather alludes to the content of the ‘consensus’ as the objective result of a coinciding perception and will (‘in idem sentire’) between the contracting parties.
